Cardiac events after NSCLC radiotherapy occur early
Cardiac events are “relatively common,” affecting 23% of patients, and occur earlier than previously thought following radiotherapy for non–small-cell lung cancer (NSCLC), according to a report in the Journal of Clinical Oncology.
Radiation-associated cardiac toxicity has long been recognized in patients treated for other thoracic cancers, but the conventional wisdom has been that it isn’t a consideration in patients with stage III NSCLC because “there are few long-term survivors to experience toxicity, given the typically long latency of radiotherapy-associated heart injury and the poor prognosis” of this cancer. However, the findings “challenge the perception that minimizing heart dose is not important in the treatment of patients with stage III NSCLC,” said Kyle Wang, MD, of University of North Carolina Hospitals, Chapel Hill, and his associates.
“Our data support minimization of heart radiation exposure whenever possible to doses lower than commonly recommended in patients with stage III NSCLC, to reduce risks of [cardiac] toxicity,” they noted.
Dr. Wang and his associates performed a retrospective post hoc analysis of data pooled from six prospective phase I and II trials that the University of North Carolina was involved in between 1996 and 2009. The studies assessed both dose-escalated radiotherapy and various chemotherapeutic regimens in 112 patients who were followed for a median of 8.8 years (range, 2.3-17.3 years). All the patients received induction chemotherapy, 90% received concurrent chemotherapy, and 25% received consolidation chemotherapy.
A total of 26 patients (23%) had at least one symptomatic cardiac event following radiotherapy: pericardial effusion (7 patients), MI (5 patients), unstable angina (3 patients), pericarditis (2 patients), significant arrhythmia (12 patients), and heart failure (1 patient). After the data were adjusted to account for competing risks of death, the 2-year rate of symptomatic cardiac toxicity was 10% and the 4-year rate was 18%. The first adverse cardiac event occurred at a median of 26 months (range, 1-84 months).
The risk of cardiac toxicities rose with increasing radiation exposure: At 2 years, the rate of cardiac events was 4% for those exposed to less than 10 Gy, 7% for those exposed to 10-20 Gy, and 21% for those exposed to greater than 20 Gy. At 4 years, those rates were 4%, 13%, and 41%, respectively. Patients whose hearts were exposed to greater than 20 Gy had a significantly higher rate of cardiac events than did those exposed to less than 10 Gy (HR, 5.47) or to 10-20 Gy (HR, 2.76).
Even though the prognosis may be poor in patients with stage III NSCLC, “they generally receive higher heart doses and may also have more comorbidities and smoking history, thus increasing risk and perhaps shortening the latency between radiotherapy and resultant heart disease,” Dr. Wang and his associates said (J Clin Oncol. 2017 Jan 23 [doi: 10.1200/JCO.2016.70.0229]).
“In our opinion, tumor coverage should rarely be compromised to meet a heart dose constraint. However, it would be reasonable to try to limit heart mean dose to less than 20 Gy (lower if possible) on the basis of the high event rate we observed in patients exceeding this dose (21% at 2 years and 41% at 4 years). Sophisticated radiation treatment planning techniques (e.g., [intensity-modulated radiation therapy]) and charged-particle therapy with protons or carbon ions may provide increased flexibility to generate more conformal treatment plans and reduce heart dose, which could potentially improve the clinical outcomes in patients with stage III NSCLC,” they added.
This is the first report to clearly associate radiation doses with clinically significant cardiac events in patients with locally advanced NSCLC treated with modern radiotherapy techniques, and it suggests that these events happen much earlier than conventionally believed.
Perhaps cardiac risk didn’t matter so much when, historically, the life expectancy of this patient population was only 2 years. But given the improvements in survival over the last 2 decades, together with the findings of Wang et al., the era of indiscriminate irradiation to the heart should end.

Judge blocks Aetna-Humana merger
A federal judge has blocked a megamerger between health insurance giants Aetna and Humana, ruling that the consolidation would violate antitrust laws and reduce competition.
In a Jan. 23 decision, Judge John D. Bates of the U.S. District Court for the District of Columbia denied Aetna’s $37 billion plan to purchase Humana, following a month-long trial that began in early December. The court was unpersuaded that the efficiencies generated by the merger would be “sufficient to mitigate the anticompetitive effects for consumers in the challenged markets,” Judge Bates said in his opinion.
The U.S. Department of Justice, which challenged the merger, called the ruling a victory for patients, particularly seniors and working families.
“Competition spurs health insurers to offer higher quality and more affordable health insurance to seniors who choose Medicare Advantage plans and to low-income families and individuals who purchase insurance from public exchanges,” Brent Snyder, deputy assistant attorney general, said in a statement. “Aetna attempted to buy a formidable rival, Humana, instead of competing independently to win customers. Millions of consumers have benefited from competition between Aetna and Humana, and will continue to benefit because of today’s decision to block this merger.”
The Department of Justice, eight states, and the District of Columbia sued Aetna and Humana after an investigation into their proposed July 2015 merger. The government argued that the companies compete head-to-head in the Medicare Advantage and public exchange markets, and that such competition would be lost following the merger to the significant detriment of patients. Aetna and Humana argued their proposed merger would not substantially lessen competition because of the government’s regulatory authority over Medicare Advantage, the threat of entry by new competitors, and the defendants’ proposed divestiture of a portion of their Medicare Advantage business to insurer Molina Healthcare. The insurers also asserted that no current competition between the two companies exists in the 17 complaint counties because Aetna has decided not to compete in those counties in 2017. Judge Bates disagreed.
“The merger would likely substantially lessen competition in the market for individual Medicare Advantage in all 364 complaint counties,” Judge Bates said in his opinion. “This conclusion is based on identification of the proper product market, the overwhelming market concentration figures generated by the merger, and the considerable evidence of valuable head-to-head competition between Aetna and Humana, which the merger would eliminate. The companies’ rebuttal arguments are unpersuasive.”
The American Medical Association praised the ruling.
“Elderly patients were the big winners today as a federal court imposed an injunction on Aetna’s $37 billion acquisition of Humana,” AMA president Andrew W. Gurman, MD, said in a statement. “Aetna’s strategy to eliminate head-to-head competition with rival Humana posed a clear and present threat to the quality, accessibility, and affordability of health care for millions of seniors. The AMA applauds the extraordinarily well-documented, comprehensive, fact-based ruling of U.S. District Judge John D. Bates, which acknowledged that meaningful action was needed to preserve competition and protect high-quality medical care from unprecedented market power that Aetna would acquire from the merger deal.”
Another ruling is expected soon in the $48 billion planned merger between Anthem and Cigna, which is also being challenged by the Justice department. A trial in that case wrapped up in late December in front of U.S. District Court for the District of Columbia Judge Amy Berman.

AAP: Teen access to abortion care is a right
.
“Genuine concern for the best interests of minors argues strongly against mandatory parental consent and notification laws,” the statement authors wrote in the updated policy statement, “The Adolescent’s Right to Confidential Care When Considering Abortion,” published online in Pediatrics.
The AAP Committee on Adolescence, which wrote the policy statement, encourages adolescents to voluntarily involve their parents – or other adults they trust – in decisions surrounding an unintended pregnancy, stating that teens who do will “likely benefit from adult experience, wisdom, emotional support, and financial support.” However, the policy statement also stresses that legally emphasizing parental involvement over a teen’s autonomy can result in barriers to care when timely access is most crucial, especially if a teen is reluctant to tell her parents of the situation (Pediatrics. 2017. doi: 10.1542/peds.2016-3861).
Currently, 37 states require some level of parental involvement in an adolescent’s decision to pursue an abortion. Most of these states will allow a minor to terminate a pregnancy without parental consent in the case of a medical emergency; about half waive the parental involvement requirement when there is evidence of incest, abuse, or neglect. All states with parental involvement laws also have a so-called judicial bypass, allowing a minor to obtain an abortion with a court’s approval; however, because the process can take as long as several weeks, access to medical treatment can be delayed, upping the risk of complications from later-term abortions. Data cited in the statement indicate that following the enactment of parental involvement laws in three states, second-trimester abortion rates increased by as much as 21% (N Engl J Med. 2006;354[10]:1031-8; Fam Plann Perspect. 1995;27[3]:120-2; Women Health. 1995;22[3]:47-58.
Even when a judicial bypass is obtained, a study of 12,000 such petitions obtained in Minnesota and Massachusetts showed that only 21 of them were denied, and half of those were overturned, meaning the outcome was the same, but the potential risks of delaying care were higher (J Adolesc Health. 1991;12[2]:143-7). The AAP statement suggests physicians learn their state requirements for judicial bypass, if any.
The updated statement also refutes the notion that parental involvement laws improve communication within families and lead to better health outcomes for teens facing an unintended pregnancy. Instead, the statement says that on average, minors who discuss pregnancy termination with their parents do so at the same rate as in states with and without such laws, and that a teen is more likely to involve her parents than not, a likelihood that increases the younger a teen is. When she doesn’t choose to discuss it with parents, fear of some sort of danger such as an escalation in any ongoing family tensions, coercion into a decision, or abuse of some kind is often why (Contraception. 2010 Oct;82[4]:310-3; Fam Plann Perspect. 1992 Jul-Aug;24[4]:148-54, 173).
“In a perfect world of butterflies and unicorns, parents and kids have a perfect relationship, but we know that’s not always true. There can be significant discord in families, and parental notification could result in harm to the adolescent, or risk to the family’s tapestry with significant consequences for the family and the adolescent,” Dr. Breuner said.
Dr. Beers argued that while she believed most parents would rather be the one their teen turns to for advice in such a situation, it’s not possible to legislate trust within families, each of which has its own history and unique family culture and style of communication. “This is the type of conversation that doesn’t begin with the acute event. This is the kind of conversation that should begin [at] a very early age between a parent and a child,” she said.
The physician’s role, according to Dr. Beers, is to ensure parents and their children have “a shared understanding of the facts to [rely on] when they talk about what is important to their family and what their family values are.”
The updated statement, originally issued in 1993, roughly coincides with the release of a new Guttmacher Institute report indicating that abortion rates in the United States are at their lowest since passage of Roe v. Wade in 1973. The report credits lower unintended pregnancy rates and better access to contraception, not restrictive abortion legislation, for the drop. The AAP’s updated statement also comes within days of the inauguration of President Donald Trump, whose run-up to election featured rhetoric challenging the status quo of federal abortion laws.
Dr. Breuner said the timing was a coincidence, and that plans to reissue the statement began over 3 years ago as she and her colleagues drew up plans to recommit their membership to protecting the reproductive rights of their patients. “With all of the regulations, restrictions, and decreased access to [abortion] care that are occurring, the academy wanted members to know just how much more difficult it is to obtain an abortion,” she said, noting that access and confidentiality are not the same. “If you can’t get an abortion, what difference does confidentiality make?”
Last year, the Supreme Court reversed a law that would have greatly limited access to abortion in Texas by closing all but nine clinics statewide, burdening them with care for tens of thousands of women annually. Also in 2016, citing a Constitutional violation of a woman’s right to privacy, a federal judge blocked an Indiana law signed by then governor and now vice president Mike Pence, that restricted the reasons a woman could cite to seek an abortion.
Dr. Breuner views this as an erosion of the rights of all women to comprehensive reproductive care, including those of adolescents. “You can’t ‘Google Map’ how to figure this out anymore. The roads are closed and all the ways people say you can get there don’t really lead you there,” she said, noting that the AAP’s statement is in line with several other professional medical societies, including the American College of Obstetricians and Gynecologists and the American Medical Association.
Regardless of timing, the statement should be viewed not through a political – or even partisan – lens, but as a reaffirmation of “core values,” according to Dr. Beers. “We do live in divided times. I think it’s important to circle back to our core values as pediatricians. That’s the agenda – making sure adolescents are healthy, safe, and supported.”

Dr. Breuner said the timing was a coincidence, and that plans to reissue the statement began over 3 years ago as she and her colleagues drew up plans to recommit their membership to protecting the reproductive rights of their patients. “With all of the regulations, restrictions, and decreased access to [abortion] care that are occurring, the academy wanted members to know just how much more difficult it is to obtain an abortion,” she said, noting that access and confidentiality are not the same. “If you can’t get an abortion, what difference does confidentiality make?”
Last year, the Supreme Court reversed a law that would have greatly limited access to abortion in Texas by closing all but nine clinics statewide, burdening them with care for tens of thousands of women annually. Also in 2016, citing a Constitutional violation of a woman’s right to privacy, a federal judge blocked an Indiana law signed by then governor and now vice president Mike Pence, that restricted the reasons a woman could cite to seek an abortion.
Dr. Breuner views this as an erosion of the rights of all women to comprehensive reproductive care, including those of adolescents. “You can’t ‘Google Map’ how to figure this out anymore. The roads are closed and all the ways people say you can get there don’t really lead you there,” she said, noting that the AAP’s statement is in line with several other professional medical societies, including the American College of Obstetricians and Gynecologists and the American Medical Association.
Regardless of timing, the statement should be viewed not through a political – or even partisan – lens, but as a reaffirmation of “core values,” according to Dr. Beers. “We do live in divided times. I think it’s important to circle back to our core values as pediatricians. That’s the agenda – making sure adolescents are healthy, safe, and supported.”

“Genuine concern for the best interests of minors argues strongly against mandatory parental consent and notification laws,” the statement authors wrote in the updated policy statement, “The Adolescent’s Right to Confidential Care When Considering Abortion,” published online in Pediatrics.
The AAP Committee on Adolescence, which wrote the policy statement, encourages adolescents to voluntarily involve their parents – or other adults they trust – in decisions surrounding an unintended pregnancy, stating that teens who do will “likely benefit from adult experience, wisdom, emotional support, and financial support.” However, the policy statement also stresses that legally emphasizing parental involvement over a teen’s autonomy can result in barriers to care when timely access is most crucial, especially if a teen is reluctant to tell her parents of the situation (Pediatrics. 2017. doi: 10.1542/peds.2016-3861).
Currently, 37 states require some level of parental involvement in an adolescent’s decision to pursue an abortion. Most of these states will allow a minor to terminate a pregnancy without parental consent in the case of a medical emergency; about half waive the parental involvement requirement when there is evidence of incest, abuse, or neglect. All states with parental involvement laws also have a so-called judicial bypass, allowing a minor to obtain an abortion with a court’s approval; however, because the process can take as long as several weeks, access to medical treatment can be delayed, upping the risk of complications from later-term abortions. Data cited in the statement indicate that following the enactment of parental involvement laws in three states, second-trimester abortion rates increased by as much as 21% (N Engl J Med. 2006;354[10]:1031-8; Fam Plann Perspect. 1995;27[3]:120-2; Women Health. 1995;22[3]:47-58.
Even when a judicial bypass is obtained, a study of 12,000 such petitions obtained in Minnesota and Massachusetts showed that only 21 of them were denied, and half of those were overturned, meaning the outcome was the same, but the potential risks of delaying care were higher (J Adolesc Health. 1991;12[2]:143-7). The AAP statement suggests physicians learn their state requirements for judicial bypass, if any.
The updated statement also refutes the notion that parental involvement laws improve communication within families and lead to better health outcomes for teens facing an unintended pregnancy. Instead, the statement says that on average, minors who discuss pregnancy termination with their parents do so at the same rate as in states with and without such laws, and that a teen is more likely to involve her parents than not, a likelihood that increases the younger a teen is. When she doesn’t choose to discuss it with parents, fear of some sort of danger such as an escalation in any ongoing family tensions, coercion into a decision, or abuse of some kind is often why (Contraception. 2010 Oct;82[4]:310-3; Fam Plann Perspect. 1992 Jul-Aug;24[4]:148-54, 173).
“In a perfect world of butterflies and unicorns, parents and kids have a perfect relationship, but we know that’s not always true. There can be significant discord in families, and parental notification could result in harm to the adolescent, or risk to the family’s tapestry with significant consequences for the family and the adolescent,” Dr. Breuner said.
Dr. Beers argued that while she believed most parents would rather be the one their teen turns to for advice in such a situation, it’s not possible to legislate trust within families, each of which has its own history and unique family culture and style of communication. “This is the type of conversation that doesn’t begin with the acute event. This is the kind of conversation that should begin [at] a very early age between a parent and a child,” she said.
The physician’s role, according to Dr. Beers, is to ensure parents and their children have “a shared understanding of the facts to [rely on] when they talk about what is important to their family and what their family values are.”
The updated statement, originally issued in 1993, roughly coincides with the release of a new Guttmacher Institute report indicating that abortion rates in the United States are at their lowest since passage of Roe v. Wade in 1973. The report credits lower unintended pregnancy rates and better access to contraception, not restrictive abortion legislation, for the drop. The AAP’s updated statement also comes within days of the inauguration of President Donald Trump, whose run-up to election featured rhetoric challenging the status quo of federal abortion laws.

Symptoms don’t worsen during pregnancy in most PsA patients
Psoriatic arthritis disease activity tended to improve or stabilize during pregnancy and the first year after giving birth, even outpacing controls, in a small retrospective cohort study.
“The outcome of pregnancy in PsA [psoriatic arthritis] patients is excellent,” investigators from the University of Toronto Psoriatic Arthritis Program reported. They found that “arthritis activity has a favorable course during pregnancy in almost 60% of the pregnancies, while the skin disease shows a favorable course in close to 90% of the pregnancies.”
According to the researchers, led by Ari Polachek, MD, of the Centre for Prognosis Studies in the Rheumatic Diseases at Toronto Western Hospital, previous research has found that rheumatoid arthritis improves in most pregnant women with the condition but then worsens in the year after birth, while most patients with ankylosing spondylitis don’t get better or worse. Limited research suggests psoriasis tends to improve during pregnancy and then flares afterward.
For the new study, researchers tracked 29 pregnant PsA patients with 42 total pregnancies who had a mean age of about 34 years at the beginning of pregnancy and matched them with 67 control patients with PsA who were not pregnant and had an average age of about 35 years. They had all visited the University of Toronto Psoriatic Arthritis Clinic during 1990-2015 (Semin Arthritis Rheum. 2017 Jan 16. doi: 10.1016/j.semarthrit.2017.01.002).
Among the 41 pregnancies in women who began follow-up prior to pregnancy, 13 (32%) had an unfavorable course of disease activity marked by worsening during 8 (20%) of the pregnancies or stable high disease activity during 5 (12%). The course of disease activity was more favorable for 24 (59%) pregnancies, in which it improved in 11 (27%) and stayed stable at a low disease level in 13 (32%). Four pregnancies (10%) had a mixed pattern of improvement followed by worsening.
The 1-year postpartum period during 40 pregnancies showed that stable or worsening symptoms were most common: 8 (20%) had improvement and 13 (32.5%) had stable low disease activity, while another 16 (4%) worsened and 3 (8%) had a mixed course of improvement followed by worsening.
After they controlled the results to account for various factors, the researchers found that pregnancy appeared to be especially beneficial for skin-related PsA symptoms. The likelihood of improved skin activity during pregnancy rose significantly (odds ratio, 7.7; 95% confidence interval, 1.8-23.5; P = .004) when compared with a matched period among controls, but this was no longer the case during the year after birth (OR, 0.4; 95% CI, 0.2-1.4; P = .60).
The likelihood of improved joint symptoms during pregnancy also rose, but not to a significant extent (OR, 2.1; 95% CI, 0.8-5.1; P = .10), and the effect on joints was not significant in the year after pregnancy (OR, 1.4; 95% CI, 0.5-3.4; P = .50).
There was a declining use of medications among the patients during pregnancy, particularly in the second and third trimesters, but two-thirds of the patients were treated with medications for PsA during this time, including NSAIDs (41%), disease-modifying antirheumatic drugs (35%), and biologic agents (26%).
The researchers speculated that hormonal changes during pregnancy may explain the improvement in skin activity. However, they noted that women with PsA who have multiple pregnancies don’t tend to have the same experiences each time: “Most of the women with more than one pregnancy had different joint disease course during their own different pregnancies and postpartum periods. Accordingly, this suggests that each woman needs specific evaluation and treatment adjustment during each pregnancy.”

Lyme arthritis changes its immune response profile if it persists after antibiotics
The persistence of Lyme arthritis after treatment with antibiotics comes with a shift from an immune response expected for bacterial infection to one characterized by chronic inflammation, synovial proliferation, and breakdown of wound repair processes, according to an analysis of microRNA expression in patients before, during, and after infection.
Based on the findings, investigators led by Robert B. Lochhead, PhD, of Massachusetts General Hospital, Boston, said that they “suspect that, in humans, genetic variables determine whether the response to B. burgdorferi infection elicits an appropriate wound repair response … or a maladaptive inflammatory cellular response and arrest of wound repair processes.”
The investigators studied synovial fluid or tissue from 32 patients with LA who were representative of the spectrum of disease severity and treatment responses seen in this disease. In 18 patients for whom synovial fluid samples were available, 5 illustrated the differences in miRNA expression that occur from the time before any antibiotic treatment to the time after antibiotic treatment that successfully resolves arthritis symptoms, and 13 showed how an incomplete response to antibiotic treatment can affect miRNA expression. The expression profile of miRNA in synovial tissue samples from another 14 patients who underwent arthroscopic synovectomies 4-48 months after oral and intravenous antibiotics demonstrated the change in immune response seen in postinfectious LA.
The group of five patients with synovial fluid samples who were referred prior to antibiotic therapy when they had active B. burgdorferi infection (group 1) had a history of mild to severe knee swelling and pain for a median duration of 1 month prior to evaluation and the start of antibiotic treatment. A 1-month course of oral doxycycline resolved arthritis in three of the patients, and the other two continued to have marked knee swelling that later resolved after 1 month of IV ceftriaxone. Of six different miRNAs that the investigators measured, five were at low levels in these patients. The lone exception was a hematopoietic-specific miRNA, miR-223, which is abundantly expressed in polymorphonuclear lymphocytes (PMNs) and is associated with downregulation of acute inflammation and tissue remodeling.
In the group of 13 who still had joint swelling despite oral or IV antibiotics (group 2), only 2 had resolution of their swelling after IV antibiotics. Most of the remaining 11 had successful treatment with methotrexate. The synovial fluid samples for seven patients were collected after oral antibiotics but before IV antibiotics, and in the other six the samples were collected after both therapies. These 13 patients had significantly lower white blood cell counts in synovial fluid, fewer PMNs, and greater percentages of lymphocytes and monocytes than did group 1 patients. The five miRNAs that were found at low levels among the patients in group 1 were higher in these patients, which “suggested that the nature of the arthritis had changed after spirochetal killing.” The higher miR-223 levels seen in group 1 also occurred in group 2.
A separate analysis of synovial fluid samples from four patients with osteoarthritis and six patients with RA showed that levels of the six miRNAs from RA patients were similar to those of patients from group 2, and the low levels that were observed for most of the miRNAs in group 1 were similar to those seen in OA patients.
The investigators found that the five miRNAs with elevated levels in group 2 patients, but not miR-223, were positively correlated with arthritis duration after start of oral antibiotic therapy. B. burgdorferi IgG antibody titers negatively correlated with some of the elevated miRNAs in group 2.
The investigators analyzed a larger set of miRNAs in the synovial tissue samples obtained from 14 patients who underwent synovectomies for treatment of persistent synovitis a median of 15.5 months after they had undergone 2-3 months of antibiotic therapy (group 3). Some of the miRNAs overexpressed in these postinfectious LA samples, relative to samples from five OA patients, were associated with proliferative, tumor-associated responses and regulation of inflammatory processes. However, miRNAs overexpressed in tissues from OA patients relative to postinfectious LA patients were thought to affect genes that control tissue remodeling and cell proliferation, but not inflammation. The “distinct oncogenic miRNA profile” exhibited by postinfectious synovial tissue, according to the investigators, showed that “in these patients, the transition to the postinfectious phase was blocked by chronic inflammation, which stalled the wound repair process.”
The investigators concluded that “miRNAs hold promise as potential biomarkers to identify LA patients who are developing maladaptive immune responses during the period of infection. In such patients, it will be important to learn whether simultaneous treatment with antibiotics and DMARDs, rather than sequential treatment with these medications, will reduce the period of therapy and improve outcome, creating a new paradigm in treatment of this form of chronic inflammatory arthritis.”

Ohio progestogen program reduced early preterm births
A statewide progestogen promotion program that aimed to reduce early premature births in Ohio by 10% is exceeding its goals, thanks to a joint effort of maternity hospitals and clinics, Ohio’s Medicaid program, Medicaid insurers, and service agencies.
The organizations joined forces via the Ohio Perinatal Quality Collaborative (PQC) beginning in 2014, and by February 2016 a sustained reduction in singleton births before 32 weeks of gestation was evident. The reduction was particularly pronounced among women with a prior preterm birth, African American women, and women on Medicaid, with reductions of 20.5%, 20.3%, and 17.1%, respectively, according to Jay D. Iams, MD, the obstetrics lead for the collaborative and emeritus professor at Ohio State University; Mary S. Applegate, MD, medical director for the Ohio Department of Medicaid; and their colleagues.
What was the key driver of their success? A collaborative effort among local- and system-level organizations and individuals to overcome the numerous barriers to providing the preventive, highly effective progestogen treatments to at-risk women, according to Dr. Iams and Dr. Applegate.
“Ohio has one of the worst rates of infant mortality and a high rate of premature birth – especially very early premature birth [before 32 weeks],” Dr. Iams said in an interview.
Those very early births account for more than half of infants who die before their first birthday, so while 13% may seem like a small number, it has the potential to have a very large effect on long-term health and infant mortality, he said.
The Ohio program was developed in the wake of practice guidelines from the Society for Maternal-Fetal Medicine and the American College of Obstetricians and Gynecologists, both issued in 2012, on the use of progestogens to reduce the incidence of preterm birth (Am J Obstet Gynecol 2012;206:376-86 and Obstet Gynecol 2012;120:964-73).
Large, high-quality, randomized placebo-controlled trials supported the use of 17-alpha hydroxyprogesterone caproate (17-p) injections or progesterone administered vaginally, and the Ohio Department of Medicaid and Ohio Department of Health asked the Ohio PQC – a volunteer network of stakeholders dedicated to improving perinatal health outcomes – to design a statewide quality improvement project to promote progestogen prescribing for eligible women.
To facilitate identification and management of women at risk for preterm birth, clinicians were asked to notify the Ohio Medicaid agency when a patient became pregnant so that a care manager could be assigned to help remove barriers to care.
“It turned out that piece of it was key,” she said. “It was the communication between these two, and then just dealing with whatever the issues were that actually made the difference.”
Care managers helped the patients navigate the system by notifying the county to make sure they didn’t “fall off Medicaid,” by addressing transportation issues to ensure patients could get to their weekly treatment visits, and by addressing cultural issues, for instance.
“It never really occurred to clinicians that Medicaid could actually be helpful in finding women and actually doing the right thing for them,” Dr. Applegate said, explaining that most only thought of Medicaid as “after the fact ... the doctors do what they need to and afterward we pay claims.”
“So this was kind of a new concept to them,” she added.
In fact, a quality improvement plan was structured on the managed care plan side, just like one was structured on the clinical side, she said. “In essence we have these parallel systems that were actually connecting, identifying barriers as we went,” Dr. Applegate said.
In the article in Obstetrics & Gynecology, the investigators describe the quality improvement processes, including training, evidence reviews, and strategy sharing. Steps toward efficient identification of eligible patients and prescription of progestogens were developed, and participating sites were encouraged to follow them.
At the system level, efforts focused on maintaining the patient’s Medicaid coverage, expanding eligibility for Medicaid, and streamlining forms and processes to improve efficiency and improve data collection.
The effects of these cumulative efforts emerged over time, with the drop in early premature births becoming apparent about 16-18 months after the project started. The investigators reviewed other possible causes for the decrease, such as an increase in the rate of cervical cerclage, but confirmed that the change was likely the result of the progestogen promotion program, Dr. Iams said.
In all, 2,562 women were eligible for progestogen at participating clinics between Jan. 1, 2014, and Nov. 30, 2015. Most (93%) were eligible because of a prior preterm birth, and the remainder had a short cervix on ultrasound. A progestogen was prescribed at or before 20 6/7 weeks of gestation in 64%, and at or before 24 6/7 weeks gestation in 72%. Injections were prescribed in 65%, and vaginal preparations in 30%; 5% were prescribed both or had no documentation of the formulation.
The progestogen program had no effect on the overall rate of births before 37 weeks. “So we can’t say that we changed the prematurity rate, but we changed the rate of births that are most likely to result in infant death and we were pretty excited about that,” Dr. Iams said.
Next steps for the program include expansion to rural areas and development of an electronic notification system to further streamline communication between the various players (pharmacies, insurance companies, Medicaid, etc.). Dr. Applegate said she also hopes to harness the lessons of this program for use in other high-risk scenarios, such as pregnancies complicated by substance abuse.
As for whether other states will follow Ohio’s lead, Dr. Iams said almost all the states are involved in quality improvement efforts, including several with programs similar to Ohio’s.
In fact, the Centers for Disease Control and Prevention is currently providing support to PQCs in California, Illinois, Massachusetts, North Carolina, and New York, in addition to the Ohio PQC, according to Zsakeba Henderson, MD, a medical officer on the CDC division of reproductive health in Atlanta.
“CDC has developed a resource guide to help develop and advance the work of state PQCs, and in collaboration with March of Dimes has spearheaded the development and launch of the National Network of Perinatal Quality Collaboratives,” she said. “This network is a consultative resource for state PQCs, with a mission is to support the development and enhance the ability of state perinatal quality collaboratives to make measurable improvements in statewide maternal and infant health care and health outcomes.”
Dr. Applegate stressed the importance of collaboration in achieving results.
“I think the message is you can’t do it in a silo. It really has taken this collaborative and fairly comprehensive approach to understand not only how complex the system is, but how complicated people’s lives are. You just have to hang in there over lots and lots of weeks to get the outcome you want,” she said, adding that the effort is well worth it.
“These are babies that are born weighing less than a pound and a half. When we’re helping them be born closer to term that changes the next 60 years of their life,” she said. “It totally changes not just that baby’s life, but the hardship that comes to that family as well, so the impact is actually huge.”

2-week left-sided pelvic pain
(A) Simple ovarian cyst INCORRECT
Here is an example of a well circumscribed round or oval anechoic, avascular simple ovarian cyst with posterior acoustic enhancement and thin smooth walls.1 No septations or solid components are identified.
(B) Hemorrhagic cyst CORRECT
This type of cyst is well circumscribed and hypoechoic, with posterior acoustic enhancement and demonstrates a lacy reticular pattern of internal echoes due to fibrin strands (long arrow). The internal echoes also may be solid appearing with concave margins (short arrow) due to retractile hemorrhagic clot.1 The absence of internal vascular flow on color Doppler helps differentiate it from the solid components seen in ovarian neoplasm.
(C) Endometrioma INCORRECT
This mass is a well-circumscribed hypoechoic cyst with homogeneous ground glass or low level echoes and increased through transmission.1 It is also avascular without solid components.
(D) Dermoid INCORRECT
This common benign ovarian tumor has varying appearances. The most common appearance is a cystic lesion with a focal echogenic nodule (long arrow) protruding into the cyst (Rokitansky nodule).2 The second most common appearance is a focal or diffuse hyperechoic mass with areas of acoustic shadowing (arrowhead) from the sebaceous material and hair (tip of the iceberg sign). A third common appearance is a cystic lesion with multiple thin echogenic bands (lines and dots), which are hair floating within the cyst (short arrow). There is no internal vascular flow identified.
(E) Cystic ovarian neoplasm INCORRECT
These are large complex masses with both cystic and solid components demonstrating internal vascular flow. They usually demonstrate a thick irregular wall, multiple septations, and nodular papillary projections.3

Building a cancer genetics and prevention program
Gastroenterologists offer more than just high-quality colonoscopy for colon cancer prevention. We often are the specialists who first recognize a genetic cancer syndrome during our endoscopy or clinic sessions. The patient who piqued my interest in colon cancer genetics was a 24-year-old woman who was referred for postoperative nausea after a hysterectomy for early stage uterine cancer (that alone should have raised alarm bells). Endoscopy revealed (by happenstance) a stomach coated with polyps. This led to a colonoscopy and diagnosis of familial adenomatous polyposis (uterine cancer within FAP is unusual but reported, for those of you studying for boards). In 1991, no coordinated genetics program existed within my practice so I arranged referrals to genetic counselors, surgeons, and pathologists. This led to the discovery of FAP and early stage (and curable) cancers in her two brothers and her father, in addition to extended pedigree analysis that established multi-organ cancer risks in other relatives. Years later, she brought her two adopted children to meet me and told me of lighting candles in my honor during an American Cancer Society walk. This is why we become doctors.
In this column, Dr. Xavier Llor describes the cancer genetics program he and others have built at Yale. It provides practical steps that can be taken by health system or community-based gastroenterologists to recognize and manage these complex syndromes. We are the specialists on the front lines and Dr. Llor helps us provide the coordinated care our patients expect from us.

Among all common cancers, breast and colon have the highest percentage of cases that are due to hereditary syndromes. Many of the responsible genes have been identified, and the last few years have seen an increase in uptake of genetic testing supported by the refinement of the clinical criteria suggestive of these syndromes as well as the clear improvement in outcomes as a result of the adoption of cancer preventive measures in mutation carriers.1 In spite of this, genetic testing for colorectal cancer (CRC) syndromes is not ordered as often as it should be according to the prevalence of these syndromes.2 In contrast, testing for hereditary breast cancer has become more generalized, and the threshold for ordering genetic testing in the latter is often lower than for CRC. The are several reasons for this: 1) much greater awareness, by both providers and the general public, of hereditary breast cancer conditions; 2) fewer providers with expertise in CRC genetics; 3) lack of a systematic approach to identify patients with potential CRC syndromes; and 4) absence of a clear premorbid phenotype for the most common of all CRC syndromes, Lynch syndrome.3
The recent recommendation in practice guidelines to screen all CRC tumors for Lynch syndrome either with immunohistochemistry to evaluate mismatch repair (MMR) protein expression or through tandem repeat analysis to test for microsatellite instability4 has highlighted that about 10% of all CRCs (a percentage consistently seen in different ethnic groups5) need further cancer genetic evaluation, and many will require sequencing of germline DNA. Although data on cost-effectiveness of this approach are somewhat conflicting,6,7 it is sensible because it is systematic, and studies have shown an increase in diagnostic yield through universal tumor screening.8 Unfortunately, in practice, often suspicious tumor testing results are not followed up by cancer genetics referrals, and many patients with CRC syndrome remain undiagnosed.
Patients with oligopolyposis (fewer than 100 polyps over time) also present diagnostic challenges. Some have attenuated familial adenomatous polyposis because of an APC mutation or MUTYH-associated polyposis. Recent findings have revealed other less commonly mutated genes that also result in oligopolyposis and a significant CRC risk: polymerases POLE and POLD1, GREM1, MCM9, or NTHL1. Because of the relatively low number of polyps in many of these syndromes and the lack of a systematic strategy to add up all polyps diagnosed over time, we not uncommonly fail to suspect some polyposis syndromes. Furthermore, the mixed pattern of polyps that is often associated with some of the mentioned mutated genes adds an extra challenge to diagnosing these cases.
Once individuals with CRC syndromes are identified, the challenge is to provide them with the care that they need, because many gastroenterologists, oncologists, and other health care providers are not extremely familiar with the current options for these patients.
In summary, there is a need to find systematic ways to triage and appropriately refer patients with a potential CRC syndrome to cancer genetics specialists so patients and their families can benefit from proper diagnosis and cancer preventive measures.
Building a comprehensive cancer genetics program
Although implementing systematic approaches is key to selecting individuals at risk, the complexity of caring for these patients demands a service that can stand up to the multiple challenges. For instance, most CRC syndromes are in fact multi-cancer syndromes with an increased risk of cancer and other pathologies in different organs beside the colon. Furthermore, the psychological implications of having a heritable cancer condition often take an important toll on affected families, with common feelings of guilt for having passed the mutated genes to the offspring.
Thus, to provide the best care to affected families, there is a tremendous need for well-organized and comprehensive cancer genetics services that are capable of responding to the multiple needs of these families so state-of-the-art cancer preventive measures can be carried out and multilevel support can be provided. The mentioned considerations were the guiding force in the creation of the Smilow Cancer Genetics and Prevention Program (SCGPP) at Yale. Thus, we established a comprehensive program that brings together health professionals specializing in different aspects of these patients’ care that ensures their proper attention in a longitudinal fashion, making the program their home for health care. We integrated in the program, among others, physician leaders in gastrointestinal (GI), breast, gynecological, endocrine, and genitourinary high-risk malignancies; genetic counselors; an advanced practice registered nurse specializing in cancer prevention and risk reduction; and a scientific director who leads the Clinical Laboratory Improvement Amendments–certified laboratory at Yale that offers in-house genetic testing, including full exome sequencing. The SCGPP was started in July 2015, and it currently provides more than 250 new consultations per month.
The following are several key elements that I consider important for a cancer genetics program and how they have been addressed at the SCGPP.
Identification through risk stratification
Because the identification of all individuals who can benefit from cancer genetics consultation is complex yet essential, a comprehensive approach with different strategies is often necessary.9 Universal tumor testing is an effective tool, but other complementary approaches such as the use of questionnaires can also contribute to identifying patients in need for cancer genetics assessment. In our program, the pathology department tests for MMR protein expression in all bowel and endometrial tumors. The ones that have loss of expression of an MMR protein are reported to the SCGPP, which contacts the patient’s providers to request a referral. In a relatively short implementation time, this has already resulted in a significant increase in the number of patients referred for cancer genetics consultation and new Lynch syndrome diagnosis. On the other hand, two brief and simplified questionnaires have been developed and distributed in clinics, one for health providers and one administered directly to patients. The questionnaires contain questions related to the patient’s own cancer history, polyp history, cancer screening tests, and family history. The first one assists health care providers in identifying individuals. The second one is completed by patients, collected, and reviewed by a genetic counselor. Suitable patients are invited to a cancer genetics consultation through their primary health care providers. A third questionnaire directed to endoscopy services will be rolled out soon. This collects information on completed endoscopy procedures, polyps and cancers found, and family history.
The program is currently working with information technology to develop a system to pull from the electronic medical record (EMR) relevant information on the patient’s own medical history, family history, and endoscopy findings. A set of criteria has been established so relevant information will generate an alert for prompt referral for the SCGPP.
Because education of health care providers about these conditions is essential to foster collaboration and to help them better understand about cancer risk assessment, genetics, and what the SCGPP can offer to some of their patients, sessions are routinely held with some of them to discuss different aspects on cancer genetics.
In summary, a comprehensive and coordinated approach is key to substantially expand the number of individuals identified and referred for cancer genetics assessment.
Genetic testing
During the last few years we have witnessed changes at different levels around genetic testing that are having a tremendous impact. Some of these changes pose significant new challenges that require rapid adaptation on the providers’ side. Thus, we are quickly moving from single gene testing to panels of genes tested at once. This has resulted in unexpected findings such as mutated genes not initially suspected or variants of unknown significance that often should be interpreted in the context of the personal and family history of cancer because of the lack of definite information on their potential pathogenicity.10 Adding to that, genome-scale tumor sequencing is becoming more common as it increasingly informs on the types of anti-tumor therapies to be selected for a specific patient (precision medicine). This approach is revealing some unexpected information because in some cases it has helped identify significant mutations in the germline.11
Finally, the increasing number of commercial laboratories offering genetic testing has resulted in more competition and lower prices, in some cases to a point that direct-to-consumer charges may be even lower than insurance copayments. This is contributing to a rapid increase in individuals being tested including patients who otherwise would unlikely have been tested in the past because of lack of fulfillment of insurance criteria. The challenge for us is to be ready to help navigate the increasing amount of information obtained as a result of all these changes.
Integration of electronic platforms
In an era of full implementation of EMRs, a cancer genetics program should not simply adapt to the new environment but fully embrace it and explore the possibilities that come with it. Thus, from its inception, the SCGPP has been embracing the electronic platforms to the maximum extent so the clinical operation is streamlined and documentation is well-displayed and accessible in the EMR. The Yale health care system uses EPIC (Epic Systems, Verona, WI) as its EMR, and the SCGPP uses Progeny (Progeny Genetics LLC, Delray Beach, FL) to collect data, construct family pedigrees, and build the research registry of the Program. A joint effort by the developers of both systems has resulted in integration at different levels. Thus, after a referral is received, patients are called, registered, and asked several questions including their own cancer and polyp history as well as their family history of cancer. This assists in triaging patients to the most appropriate SCGPP provider: a genetic counselor, a disease physician leader, or a combined visit according to the established internal protocol. In all cases, for new patients with GI cancer syndromes, a combined appointment of a genetic counselor and the GI physician leader is scheduled. At the same time, patients are sent an email with a link to the Progeny online questionnaire that includes personal and family history of cancer as well as extensive clinical information. Once the questionnaire is completed, the program generates a preliminary pedigree that patients can print, and the SCGPP gets a message communicating that the patient has completed this questionnaire. Therefore, when patients are seen on consultation, providers already have the provisional data and pedigree. During the visit, information is verified and edited as needed, and the finalized pedigree goes live through a hyperlink in the EMR. Every revision results in an updated pedigree visible through the mentioned hyperlink. This process saves a considerable amount of time to the providers and increases clinic efficiency.
Informed consent for the research registry is also fully electronic, with signatures recorded in tablets that transmit the signed document to a secure server.
The necessary team approach
Another essential component of a cancer genetics program like this is the integrated and comprehensive approach to patients. Thus, in our Program, the combined appointments for GI patients with the genetic counselor and the physician leader cover all different aspects of care, and a complete plan is suggested and discussed. Once the initial assessment is finalized and genetic testing results (if ordered) are completed, patients are followed prospectively to ensure that prophylactic and cancer prevention measures are undertaken according to the updated standards of care. Complex cases are discussed with the entire team in the weekly case conference that is always followed by a scientific conference with alternating topics such as journal club, practice improvement, ongoing research projects, and extensive case reviews.
Network integration
Although the needs for cancer genetics can be found in any corner of the map, it is not realistic to believe that services like this can be provided in a consistent fashion without being part of a bigger program umbrella. In our case, Yale’s Smilow Cancer Center charged the SCGPP with the duty to provide high quality and consistent cancer genetics services to the entire network that currently includes a total of 5 affiliated hospitals and 10 care centers. To do so, all cases seen outside the main campus are brought up for discussion in the weekly case conference. Furthermore, counselors distributed throughout the network routinely also see patients in the main office, and when away, they participate in case conference and scientific conference via teleconference or videoconference. All this is considered critical to facilitate a cohesive and state-of-the-art program that extends beyond the main campus. Recently, telemedicine is used to provide consultations directly to patients so the program’s services are brought to the most remote locations. A senior genetic counselor is in charge of the network operations to facilitate all these services and help engage providers in the corresponding facilities. She regularly attends tumor board meetings in the local hospitals to help disseminate knowledge in cancer genetics as well as to assist in the identification of patients who can benefit from referral to the SCGPP.
Surveillance and recall program
Key to the success of a cancer genetics program is successfully coordinating care so preventive tests and measures are performed to decrease cancer risk. The SCGPP aims to be the home for familial and hereditary cancer patients. For these patients, this implies a strong commitment to their needs, with a special emphasis on the appropriate prophylactic and cancer surveillance measures. The registry database provides an extremely useful tool to track scheduled tests and procedures and to generate reminders. The advanced practice registered nurse meticulously follows them and ensures proper completion and review. She follows up on the scheduling of the specific tests, reviews results once these tests are completed, and brings them back to discussion with the physician leader. She also follows up on incomplete tests and helps to bring down potential barriers in the performance of these tests. Another key aspect of her job consists of facilitating the assistance of psychological support or risk reduction through lifestyle changes, such as smoking cessation or weight reduction, to patients in need of such services.
Cancer genetics research
Key to an academic program in cancer genetics like this one is to facilitate the study of familial and syndromic cancers, including aspects such as phenotype characterization or the efficacy of chemopreventive approaches. To accomplish this, a patient registry is essential. Registries are extremely useful tools that facilitate data accrual and analysis. The SCGPP registry is based on the Progeny suite that incorporates not only clinical and pedigree building components but also the genotype and sample management systems (LAB and LIMS). Thus, a fully searchable and robust database and biological sample repository have been created, and all patients are approached about participating in this institutional review board–approved registry.
Cancer prevention in nonfamilial, nonsyndromic cases
Some nongenetic factors such as diet, physical activity, or toxic exposure seem to underlie the important differences seen in CRC incidence around the world.12 Thus, interventions at this level can potentially have a very high impact for cancer prevention in all individuals. In fact, even individuals with genetic mutations that carry a high risk for developing malignancies can see their risk modified by addressing lifestyle/environmental factors.13 Thus, the SCGPP has created tools for assessment and risk stratification that take the mentioned factors into account and create a roadmap for primary prevention. The tools include questionnaires on all environmental exposures, lifestyle factors, and medications the patient is exposed to and that can influence cancer risk. The information is reviewed in a special clinic session, and all services to help modify risk factors are offered to the patient.
Conclusions
There is a clear need for GI cancer genetics services to reach all patients who can benefit from them, and at the same time the field is rapidly growing in complexity. More than ever, these services demand a multidisciplinary approach, with experts leading the care of these patients in a coordinated fashion with the rest of the health care community. However, payers have not fully recognized these complexities, and some critical aspects such as genetic counseling services are not always properly reimbursed. As we shape up the present and future of health care that should be fully personalized and patient-centered, embracing new ways of delivering it, we need to engage all the players and help them understand what this takes and the rewards in the form of better outcomes that will come with it.

Gastroenterologists offer more than just high-quality colonoscopy for colon cancer prevention. We often are the specialists who first recognize a genetic cancer syndrome during our endoscopy or clinic sessions. The patient who piqued my interest in colon cancer genetics was a 24-year-old woman who was referred for postoperative nausea after a hysterectomy for early stage uterine cancer (that alone should have raised alarm bells). Endoscopy revealed (by happenstance) a stomach coated with polyps. This led to a colonoscopy and diagnosis of familial adenomatous polyposis (uterine cancer within FAP is unusual but reported, for those of you studying for boards). In 1991, no coordinated genetics program existed within my practice so I arranged referrals to genetic counselors, surgeons, and pathologists. This led to the discovery of FAP and early stage (and curable) cancers in her two brothers and her father, in addition to extended pedigree analysis that established multi-organ cancer risks in other relatives. Years later, she brought her two adopted children to meet me and told me of lighting candles in my honor during an American Cancer Society walk. This is why we become doctors.

Among all common cancers, breast and colon have the highest percentage of cases that are due to hereditary syndromes. Many of the responsible genes have been identified, and the last few years have seen an increase in uptake of genetic testing supported by the refinement of the clinical criteria suggestive of these syndromes as well as the clear improvement in outcomes as a result of the adoption of cancer preventive measures in mutation carriers.1 In spite of this, genetic testing for colorectal cancer (CRC) syndromes is not ordered as often as it should be according to the prevalence of these syndromes.2 In contrast, testing for hereditary breast cancer has become more generalized, and the threshold for ordering genetic testing in the latter is often lower than for CRC. The are several reasons for this: 1) much greater awareness, by both providers and the general public, of hereditary breast cancer conditions; 2) fewer providers with expertise in CRC genetics; 3) lack of a systematic approach to identify patients with potential CRC syndromes; and 4) absence of a clear premorbid phenotype for the most common of all CRC syndromes, Lynch syndrome.3
The recent recommendation in practice guidelines to screen all CRC tumors for Lynch syndrome either with immunohistochemistry to evaluate mismatch repair (MMR) protein expression or through tandem repeat analysis to test for microsatellite instability4 has highlighted that about 10% of all CRCs (a percentage consistently seen in different ethnic groups5) need further cancer genetic evaluation, and many will require sequencing of germline DNA. Although data on cost-effectiveness of this approach are somewhat conflicting,6,7 it is sensible because it is systematic, and studies have shown an increase in diagnostic yield through universal tumor screening.8 Unfortunately, in practice, often suspicious tumor testing results are not followed up by cancer genetics referrals, and many patients with CRC syndrome remain undiagnosed.
Patients with oligopolyposis (fewer than 100 polyps over time) also present diagnostic challenges. Some have attenuated familial adenomatous polyposis because of an APC mutation or MUTYH-associated polyposis. Recent findings have revealed other less commonly mutated genes that also result in oligopolyposis and a significant CRC risk: polymerases POLE and POLD1, GREM1, MCM9, or NTHL1. Because of the relatively low number of polyps in many of these syndromes and the lack of a systematic strategy to add up all polyps diagnosed over time, we not uncommonly fail to suspect some polyposis syndromes. Furthermore, the mixed pattern of polyps that is often associated with some of the mentioned mutated genes adds an extra challenge to diagnosing these cases.
Once individuals with CRC syndromes are identified, the challenge is to provide them with the care that they need, because many gastroenterologists, oncologists, and other health care providers are not extremely familiar with the current options for these patients.
In summary, there is a need to find systematic ways to triage and appropriately refer patients with a potential CRC syndrome to cancer genetics specialists so patients and their families can benefit from proper diagnosis and cancer preventive measures.
Building a comprehensive cancer genetics program
Although implementing systematic approaches is key to selecting individuals at risk, the complexity of caring for these patients demands a service that can stand up to the multiple challenges. For instance, most CRC syndromes are in fact multi-cancer syndromes with an increased risk of cancer and other pathologies in different organs beside the colon. Furthermore, the psychological implications of having a heritable cancer condition often take an important toll on affected families, with common feelings of guilt for having passed the mutated genes to the offspring.
Thus, to provide the best care to affected families, there is a tremendous need for well-organized and comprehensive cancer genetics services that are capable of responding to the multiple needs of these families so state-of-the-art cancer preventive measures can be carried out and multilevel support can be provided. The mentioned considerations were the guiding force in the creation of the Smilow Cancer Genetics and Prevention Program (SCGPP) at Yale. Thus, we established a comprehensive program that brings together health professionals specializing in different aspects of these patients’ care that ensures their proper attention in a longitudinal fashion, making the program their home for health care.

The SCGPP was started in July 2015, and it currently provides more than 250 new consultations per month.

Many of the responsible genes have been identified, and the last few years have seen an increase in uptake of genetic testing supported by the refinement of the clinical criteria suggestive of these syndromes as well as the clear improvement in outcomes as a result of the adoption of cancer preventive measures in mutation carriers.1 In spite of this, genetic testing for colorectal cancer (CRC) syndromes is not ordered as often as it should be according to the prevalence of these syndromes.2 In contrast, testing for hereditary breast cancer has become more generalized, and the threshold for ordering genetic testing in the latter is often lower than for CRC. The are several reasons for this: 1) much greater awareness, by both providers and the general public, of hereditary breast cancer conditions; 2) fewer providers with expertise in CRC genetics; 3) lack of a systematic approach to identify patients with potential CRC syndromes; and 4) absence of a clear premorbid phenotype for the most common of all CRC syndromes, Lynch syndrome.3
The recent recommendation in practice guidelines to screen all CRC tumors for Lynch syndrome either with immunohistochemistry to evaluate mismatch repair (MMR) protein expression or through tandem repeat analysis to test for microsatellite instability4 has highlighted that about 10% of all CRCs (a percentage consistently seen in different ethnic groups5) need further cancer genetic evaluation, and many will require sequencing of germline DNA. Although data on cost-effectiveness of this approach are somewhat conflicting,6,7 it is sensible because it is systematic, and studies have shown an increase in diagnostic yield through universal tumor screening.8 Unfortunately, in practice, often suspicious tumor testing results are not followed up by cancer genetics referrals, and many patients with CRC syndrome remain undiagnosed.
Patients with oligopolyposis (fewer than 100 polyps over time) also present diagnostic challenges. Some have attenuated familial adenomatous polyposis because of an APC mutation or MUTYH-associated polyposis. Recent findings have revealed other less commonly mutated genes that also result in oligopolyposis and a significant CRC risk: polymerases POLE and POLD1, GREM1, MCM9, or NTHL1. Because of the relatively low number of polyps in many of these syndromes and the lack of a systematic strategy to add up all polyps diagnosed over time, we not uncommonly fail to suspect some polyposis syndromes. Furthermore, the mixed pattern of polyps that is often associated with some of the mentioned mutated genes adds an extra challenge to diagnosing these cases.
Once individuals with CRC syndromes are identified, the challenge is to provide them with the care that they need, because many gastroenterologists, oncologists, and other health care providers are not extremely familiar with the current options for these patients.
In summary, there is a need to find systematic ways to triage and appropriately refer patients with a potential CRC syndrome to cancer genetics specialists so patients and their families can benefit from proper diagnosis and cancer preventive measures.
Building a comprehensive cancer genetics program
Although implementing systematic approaches is key to selecting individuals at risk, the complexity of caring for these patients demands a service that can stand up to the multiple challenges. For instance, most CRC syndromes are in fact multi-cancer syndromes with an increased risk of cancer and other pathologies in different organs beside the colon. Furthermore, the psychological implications of having a heritable cancer condition often take an important toll on affected families, with common feelings of guilt for having passed the mutated genes to the offspring.
Thus, to provide the best care to affected families, there is a tremendous need for well-organized and comprehensive cancer genetics services that are capable of responding to the multiple needs of these families so state-of-the-art cancer preventive measures can be carried out and multilevel support can be provided. The mentioned considerations were the guiding force in the creation of the Smilow Cancer Genetics and Prevention Program (SCGPP) at Yale. Thus, we established a comprehensive program that brings together health professionals specializing in different aspects of these patients’ care that ensures their proper attention in a longitudinal fashion, making the program their home for health care. We integrated in the program, among others, physician leaders in gastrointestinal (GI), breast, gynecological, endocrine, and genitourinary high-risk malignancies; genetic counselors; an advanced practice registered nurse specializing in cancer prevention and risk reduction; and a scientific director who leads the Clinical Laboratory Improvement Amendments–certified laboratory at Yale that offers in-house genetic testing, including full exome sequencing. The SCGPP was started in July 2015, and it currently provides more than 250 new consultations per month.
The following are several key elements that I consider important for a cancer genetics program and how they have been addressed at the SCGPP.
Identification through risk stratification
Because the identification of all individuals who can benefit from cancer genetics consultation is complex yet essential, a comprehensive approach with different strategies is often necessary.9 Universal tumor testing is an effective tool, but other complementary approaches such as the use of questionnaires can also contribute to identifying patients in need for cancer genetics assessment. In our program, the pathology department tests for MMR protein expression in all bowel and endometrial tumors. The ones that have loss of expression of an MMR protein are reported to the SCGPP, which contacts the patient’s providers to request a referral. In a relatively short implementation time, this has already resulted in a significant increase in the number of patients referred for cancer genetics consultation and new Lynch syndrome diagnosis. On the other hand, two brief and simplified questionnaires have been developed and distributed in clinics, one for health providers and one administered directly to patients. The questionnaires contain questions related to the patient’s own cancer history, polyp history, cancer screening tests, and family history. The first one assists health care providers in identifying individuals. The second one is completed by patients, collected, and reviewed by a genetic counselor. Suitable patients are invited to a cancer genetics consultation through their primary health care providers. A third questionnaire directed to endoscopy services will be rolled out soon. This collects information on completed endoscopy procedures, polyps and cancers found, and family history.
The program is currently working with information technology to develop a system to pull from the electronic medical record (EMR) relevant information on the patient’s own medical history, family history, and endoscopy findings. A set of criteria has been established so relevant information will generate an alert for prompt referral for the SCGPP.
Because education of health care providers about these conditions is essential to foster collaboration and to help them better understand about cancer risk assessment, genetics, and what the SCGPP can offer to some of their patients, sessions are routinely held with some of them to discuss different aspects on cancer genetics.
In summary, a comprehensive and coordinated approach is key to substantially expand the number of individuals identified and referred for cancer genetics assessment.
Genetic testing
During the last few years we have witnessed changes at different levels around genetic testing that are having a tremendous impact. Some of these changes pose significant new challenges that require rapid adaptation on the providers’ side. Thus, we are quickly moving from single gene testing to panels of genes tested at once. This has resulted in unexpected findings such as mutated genes not initially suspected or variants of unknown significance that often should be interpreted in the context of the personal and family history of cancer because of the lack of definite information on their potential pathogenicity.10 Adding to that, genome-scale tumor sequencing is becoming more common as it increasingly informs on the types of anti-tumor therapies to be selected for a specific patient (precision medicine). This approach is revealing some unexpected information because in some cases it has helped identify significant mutations in the germline.11
Finally, the increasing number of commercial laboratories offering genetic testing has resulted in more competition and lower prices, in some cases to a point that direct-to-consumer charges may be even lower than insurance copayments. This is contributing to a rapid increase in individuals being tested including patients who otherwise would unlikely have been tested in the past because of lack of fulfillment of insurance criteria. The challenge for us is to be ready to help navigate the increasing amount of information obtained as a result of all these changes.
Integration of electronic platforms
In an era of full implementation of EMRs, a cancer genetics program should not simply adapt to the new environment but fully embrace it and explore the possibilities that come with it. Thus, from its inception, the SCGPP has been embracing the electronic platforms to the maximum extent so the clinical operation is streamlined and documentation is well-displayed and accessible in the EMR. The Yale health care system uses EPIC (Epic Systems, Verona, WI) as its EMR, and the SCGPP uses Progeny (Progeny Genetics LLC, Delray Beach, FL) to collect data, construct family pedigrees, and build the research registry of the Program. A joint effort by the developers of both systems has resulted in integration at different levels. Thus, after a referral is received, patients are called, registered, and asked several questions including their own cancer and polyp history as well as their family history of cancer. This assists in triaging patients to the most appropriate SCGPP provider: a genetic counselor, a disease physician leader, or a combined visit according to the established internal protocol. In all cases, for new patients with GI cancer syndromes, a combined appointment of a genetic counselor and the GI physician leader is scheduled. At the same time, patients are sent an email with a link to the Progeny online questionnaire that includes personal and family history of cancer as well as extensive clinical information. Once the questionnaire is completed, the program generates a preliminary pedigree that patients can print, and the SCGPP gets a message communicating that the patient has completed this questionnaire. Therefore, when patients are seen on consultation, providers already have the provisional data and pedigree. During the visit, information is verified and edited as needed, and the finalized pedigree goes live through a hyperlink in the EMR. Every revision results in an updated pedigree visible through the mentioned hyperlink. This process saves a considerable amount of time to the providers and increases clinic efficiency.
Informed consent for the research registry is also fully electronic, with signatures recorded in tablets that transmit the signed document to a secure server.
The necessary team approach
Another essential component of a cancer genetics program like this is the integrated and comprehensive approach to patients. Thus, in our Program, the combined appointments for GI patients with the genetic counselor and the physician leader cover all different aspects of care, and a complete plan is suggested and discussed. Once the initial assessment is finalized and genetic testing results (if ordered) are completed, patients are followed prospectively to ensure that prophylactic and cancer prevention measures are undertaken according to the updated standards of care. Complex cases are discussed with the entire team in the weekly case conference that is always followed by a scientific conference with alternating topics such as journal club, practice improvement, ongoing research projects, and extensive case reviews.
Network integration
Although the needs for cancer genetics can be found in any corner of the map, it is not realistic to believe that services like this can be provided in a consistent fashion without being part of a bigger program umbrella. In our case, Yale’s Smilow Cancer Center charged the SCGPP with the duty to provide high quality and consistent cancer genetics services to the entire network that currently includes a total of 5 affiliated hospitals and 10 care centers. To do so, all cases seen outside the main campus are brought up for discussion in the weekly case conference. Furthermore, counselors distributed throughout the network routinely also see patients in the main office, and when away, they participate in case conference and scientific conference via teleconference or videoconference. All this is considered critical to facilitate a cohesive and state-of-the-art program that extends beyond the main campus. Recently, telemedicine is used to provide consultations directly to patients so the program’s services are brought to the most remote locations. A senior genetic counselor is in charge of the network operations to facilitate all these services and help engage providers in the corresponding facilities. She regularly attends tumor board meetings in the local hospitals to help disseminate knowledge in cancer genetics as well as to assist in the identification of patients who can benefit from referral to the SCGPP.
Surveillance and recall program
Key to the success of a cancer genetics program is successfully coordinating care so preventive tests and measures are performed to decrease cancer risk. The SCGPP aims to be the home for familial and hereditary cancer patients. For these patients, this implies a strong commitment to their needs, with a special emphasis on the appropriate prophylactic and cancer surveillance measures. The registry database provides an extremely useful tool to track scheduled tests and procedures and to generate reminders. The advanced practice registered nurse meticulously follows them and ensures proper completion and review. She follows up on the scheduling of the specific tests, reviews results once these tests are completed, and brings them back to discussion with the physician leader. She also follows up on incomplete tests and helps to bring down potential barriers in the performance of these tests. Another key aspect of her job consists of facilitating the assistance of psychological support or risk reduction through lifestyle changes, such as smoking cessation or weight reduction, to patients in need of such services.
Cancer genetics research
Key to an academic program in cancer genetics like this one is to facilitate the study of familial and syndromic cancers, including aspects such as phenotype characterization or the efficacy of chemopreventive approaches. To accomplish this, a patient registry is essential. Registries are extremely useful tools that facilitate data accrual and analysis. The SCGPP registry is based on the Progeny suite that incorporates not only clinical and pedigree building components but also the genotype and sample management systems (LAB and LIMS). Thus, a fully searchable and robust database and biological sample repository have been created, and all patients are approached about participating in this institutional review board–approved registry.
Cancer prevention in nonfamilial, nonsyndromic cases
Some nongenetic factors such as diet, physical activity, or toxic exposure seem to underlie the important differences seen in CRC incidence around the world.12 Thus, interventions at this level can potentially have a very high impact for cancer prevention in all individuals. In fact, even individuals with genetic mutations that carry a high risk for developing malignancies can see their risk modified by addressing lifestyle/environmental factors.13 Thus, the SCGPP has created tools for assessment and risk stratification that take the mentioned factors into account and create a roadmap for primary prevention. The tools include questionnaires on all environmental exposures, lifestyle factors, and medications the patient is exposed to and that can influence cancer risk. The information is reviewed in a special clinic session, and all services to help modify risk factors are offered to the patient.
Conclusions
There is a clear need for GI cancer genetics services to reach all patients who can benefit from them, and at the same time the field is rapidly growing in complexity. More than ever, these services demand a multidisciplinary approach, with experts leading the care of these patients in a coordinated fashion with the rest of the health care community. However, payers have not fully recognized these complexities, and some critical aspects such as genetic counseling services are not always properly reimbursed. As we shape up the present and future of health care that should be fully personalized and patient-centered, embracing new ways of delivering it, we need to engage all the players and help them understand what this takes and the rewards in the form of better outcomes that will come with it.

Mortality may be reduced when surgical ablation for AF is done with mitral operations
HOUSTON – At the time of mitral valve repair or replacement operations, the addition of surgical ablation to treat atrial fibrillation (AF) can be performed without increased risk of mortality, results from a large cohort study has demonstrated.
“Surgical ablation for atrial fibrillation performed concomitant to mitral valve repair or replacement is accepted to reduce long-term AF rates and improve quality of life, and has recently attained a class I, level of evidence A recommendation in the recent Society of Thoracic Surgeons Guidelines,” Vinay Badhwar, MD, said in an interview. Dr. Badhwar is the lead author of the STS Guidelines and senior author of the current study on mortality following surgical ablation of AF. “Nevertheless, the direct impact of surgical ablation on operative mortality has not been studied on a large scale using robust registry data.”
In an effort to examine the impact of performing or not performing surgical ablation (SA) on mortality of contemporary mitral valve repair or replacement (MVRR) operations, Dr. Badhwar, Gordon F. Murray Professor and Chair, department of cardiovascular and thoracic surgery at West Virginia University, Morgantown, W.Va., and his associates at eight other leading centers nationwide evaluated the medical records of 88,765 MVRR patients in the STS Adult Cardiac Surgery Database between July 2011 and June 2014.
The research, presented as the Richard E. Clark award winning paper in adult cardiac surgery by study leader J. Scott Rankin, MD, professor of surgery in the department of cardiovascular and thoracic surgery at West Virginia University, included cases of tricuspid repair and coronary artery bypass grafting and assessed all STS comorbid risk variables and mitral etiology for predictors of mortality. After performing multivariable logistic regression, the researchers compared risk-adjusted odds ratios for mortality by AF type at operation and SA performance: group 1 (no AF plus no SA), group 2 (no AF plus SA), group 3 (AF plus no SA), group 4 (AF plus SA), group 5 (persistent AF plus no SA), and group 6 (persistent AF plus SA).
The median age of patients ranged from 63 to 72 years. Compared with their counterparts in other groups, patients in groups 3 and 5 were older (median age of 71 and 72 years, respectively), had worse symptoms (50% in each group had NYHA class III or IV disease), had more reoperations (30% vs. 32%), and had higher unadjusted mortalities (6.7% vs. 6.6%).
Following multivariable risk adjustment, groups 2-6 with AF history plus or minus SA were referenced to group 1 patients without AF or SA. Groups 2-4 represented the overall population, and groups 5 and 6 were patients with persistent AF. Patients with AF at the time of operation not receiving SA (groups 3 and 5) had odds ratios of 1.16 and 1.17, respectively, or an increase of 16% and 17% in relative risk of mortality (P = .004 and P = .01, respectively). In groups 4 and 6, concomitant SA reduced the AF-related mortality to a level that was statistically comparable to reference baseline group 1 without a history of AF (P = .13 and P = .21, respectively).
“The present study appears to clearly illustrate the adverse effects of AF on operative mortality following MVRR,” Dr. Badhwar said. “After thorough risk adjustment, we were impressed to learn that the relative mortality risk of mitral procedures increased by nearly 15% for either paroxysmal or persistent AF, and results were similar for the two AF types. A remote history of AF with preoperative sinus rhythm immediately prior to surgery had little effect on prognosis, and these patients appeared to have outcomes more like those without AF. In patients with active AF at the time of mitral operation, SA reduced the AF-related mortality and decreased operative mortality to levels not statistically different from patients without AF.” He added that the findings of this study support the recent STS Guidelines on Surgical Ablation published in the January 2017 edition of Annals of Thoracic Surgery (Ann Thorac Surg. 2017 Jan;103[1]:329-41). “However, the ultimate decision on whether or not to add surgical ablation must always remain between the surgeon and the patient,” he said.
Dr. Badhwar acknowledged that the study is limited by the information available in version 2.73 of the STS Adult Cardiac Surgery Database. “This does highlight the ongoing need for participants in the database to provide as much complete information as possible for all patients undergoing cardiac operations, especially those involving surgical ablation,” he said.
Dr. Badhwar reported having no financial disclosures. Dr. Rankin disclosed ties with Admedus, AtriCure, and BioStable Science and Engineering.

Early, in-hospital shunt failure common among infants
HOUSTON – Among neonates and infants who underwent shunt construction as a source of pulmonary blood flow, early, in-hospital shunt failure occurred in 7.3% of cases, results from a large retrospective study showed.
“Approximately one in seven patients who experiences cardiac surgery in the first year of life undergoes construction of a systemic to pulmonary artery shunt of some type,” one of the study investigators, Marshall L. Jacobs, MD, said in an interview. The study was presented at the annual meeting of the Society of Thoracic Surgeons.
“Early failure of such shunts is an incompletely understood phenomenon which accounts for important morbidity and mortality among infants and neonates. Much of what is known about shunt failure is based on experiences reported from individual institutions. The few multicenter studies to date have been clinical trials that focused primarily on pharmacologic strategies intended to reduce the risk of shunt failure due to thrombosis. Their utility for guiding clinical decision making has been limited. Some have been underpowered; some have had limited risk adjustment of subjects.”
Dr. Do, who presented the findings at the meeting and is currently a Congenital Heart Surgery Fellow at the Children’s Hospital of Philadelphia, and a team of 11 other investigators utilized the STS Congenital Heart Surgery Database to identify 9,172 neonates and infants who underwent shunt construction as a source of pulmonary blood flow at 118 institutions from 2010 to 2015. Criteria for shunt failure included a documented diagnosis of in-hospital shunt failure, shunt revision, or catheter-based shunt intervention. The investigators used multivariable logistic regression to evaluate risk factors for in-hospital shunt failure.
Of the 9,172 at-risk neonates and infants, 674 (7.3%) experienced early, in-hospital shunt failure. “The observed rate of early shunt failure varied across the many specific types of shunts, and was lower with systemic ventricle to pulmonary artery shunts (as in the Sano modification of the Norwood procedure) than with the systemic artery to pulmonary artery shunts,” said Dr. Jacobs, who is a cardiothoracic surgeon at Johns Hopkins University, Baltimore.
In multivariable analysis, risk factors for in-hospital shunt failure included lower weight at operation for both neonates and infants, preoperative hypercoagulable state, and the collective presence of any other STS Congenital Heart Surgery Database preoperative risk factors. Neither cardiopulmonary bypass nor single ventricle diagnosis were risk factors for shunt failure. The investigators also observed that patients with in-hospital shunt failure had significantly higher rates of operative mortality (31.9% vs. 11.1%) and major morbidity (84.4% vs. 29.4%), and longer postoperative length of stay among survivors (a median of 45 vs. 22 days).
“Understanding the characteristics of the patient groups found to be at highest risk for early shunt failure is helpful in identifying individual patients that may warrant expectant surveillance, enhanced pharmacologic management, or other strategies to reduce the risk of shunt failure,” Dr. Jacobs concluded.
“But perhaps more importantly it provides key information that may be helpful in the design and development of future clinical trials and/or collaborative quality improvement initiatives designed to reduce the cost in lives and resources that is associated with early shunt dysfunction.”
He acknowledged certain limitations of the study, including its retrospective observational design and the voluntary nature of the STS Congenital Heart Surgery Database. “In addition, some potentially important variables, such as detailed data concerning preoperative test results of coagulation assays are not collected in the STS Congenital Heart Surgery Database,” he said.

HOUSTON – Among neonates and infants who underwent shunt construction as a source of pulmonary blood flow, early, in-hospital shunt failure occurred in 7.3% of cases, results from a large retrospective study showed.
“Approximately one in seven patients who experiences cardiac surgery in the first year of life undergoes construction of a systemic to pulmonary artery shunt of some type,” one of the study investigators, Marshall L. Jacobs, MD, said in an interview. The study was presented at the annual meeting of the Society of Thoracic Surgeons.
“Early failure of such shunts is an incompletely understood phenomenon which accounts for important morbidity and mortality among infants and neonates. Much of what is known about shunt failure is based on experiences reported from individual institutions. The few multicenter studies to date have been clinical trials that focused primarily on pharmacologic strategies intended to reduce the risk of shunt failure due to thrombosis. Their utility for guiding clinical decision making has been limited. Some have been underpowered; some have had limited risk adjustment of subjects.”
Dr. Do, who presented the findings at the meeting and is currently a Congenital Heart Surgery Fellow at the Children’s Hospital of Philadelphia, and a team of 11 other investigators utilized the STS Congenital Heart Surgery Database to identify 9,172 neonates and infants who underwent shunt construction as a source of pulmonary blood flow at 118 institutions from 2010 to 2015. Criteria for shunt failure included a documented diagnosis of in-hospital shunt failure, shunt revision, or catheter-based shunt intervention. The investigators used multivariable logistic regression to evaluate risk factors for in-hospital shunt failure.
Of the 9,172 at-risk neonates and infants, 674 (7.3%) experienced early, in-hospital shunt failure. “The observed rate of early shunt failure varied across the many specific types of shunts, and was lower with systemic ventricle to pulmonary artery shunts (as in the Sano modification of the Norwood procedure) than with the systemic artery to pulmonary artery shunts,” said Dr. Jacobs, who is a cardiothoracic surgeon at Johns Hopkins University, Baltimore.
In multivariable analysis, risk factors for in-hospital shunt failure included lower weight at operation for both neonates and infants, preoperative hypercoagulable state, and the collective presence of any other STS Congenital Heart Surgery Database preoperative risk factors. Neither cardiopulmonary bypass nor single ventricle diagnosis were risk factors for shunt failure. The investigators also observed that patients with in-hospital shunt failure had significantly higher rates of operative mortality (31.9% vs. 11.1%) and major morbidity (84.4% vs. 29.4%), and longer postoperative length of stay among survivors (a median of 45 vs. 22 days).
