Advances in Targeted Therapy for Breast Cancer
It is estimated that there were more than 3.1 million women living in the U.S. with a history of invasive breast cancer as of January 1, 2014, and an additional 231,840 women will be newly diagnosed with invasive breast cancer in 2015.1,2 The median age at the time of breast cancer diagnosis is 61 years. About 20% of breast cancers occur among women aged < 50 years, and 43% occur in women aged > 65 years.
The treatment and prognosis for breast cancer depend on the stage at diagnosis, the biologic characteristics of the tumor, and the age and health of the patient. The overall 5-year relative survival rate for female patients with breast cancer has improved from 75% to 90% from 1975 to 1977 and from 2003 to 2009, respectively, largely due to improvements in treatment (ie, chemotherapy, hormone therapy, and targeted drugs) and because of earlier diagnosis resulting from the widespread use of mammography and other screening tools.2
Estrogen Receptor-Positive Therapies
Women with breast cancer who test positive for hormone receptors are candidates for treatment with hormone therapy to reduce the likelihood of recurrence or as a core component of treatment for advanced disease. Currently available endocrine strategies for the treatment of estrogen receptor- (ER) positive breast cancer include targeting the ER with the antiestrogen drug tamoxifen. Another option is suppressing the amount of available ligand (estrogen) for the receptor either with gonadal suppression in premenopausal oophorectomy, or luteinizing hormonereleasing hormone agonists, or with the aromatase inhibitors (AIs) anastrozole, exemestane, and letrozole in postmenopausal women and by downregulating the receptor with fulvestrant. Given their proven efficacy and generally favorable adverse effect (AE) profile, these endocrine therapies are widely used in the treatment of both early-stage and recurrent and/or metastatic breast cancer.
Recent studies have offered new treatments for patients with hormone receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer. Innovative hormonal and targeted therapies for advanced disease as well as new data on adjuvant hormonal therapy for young high-risk patients are changing the available therapeutic options.
Advanced Metastatic Treatments
Treatment for metastatic hormone receptor-positive breast cancer has shifted from traditional cytotoxic chemotherapies to targeted therapeutic options. Most treatment guidelines, including the National Comprehensive Cancer Network guidelines, recommend targeted therapy with AIs or selective ER modulators rather than chemotherapy, except in the case of visceral crisis.3
Until recently, there had been relatively little guidance to inform which hormonal therapy was most appropriate. Aromatase inhibitors were generally reserved for postmenopausal women, whereas tamoxifen was preferred in premenopausal women.
Fulvestrant
The FDA initially approved fulvestrant, a hormone receptor downregulator, in 2002 at a 250-mg dose, following progression on an anti-estrogen therapy, such as tamoxifen in postmenopausal women with stage IV breast cancer. The FDA approval was based on similar response rates for the already approved agent anastrozole.4 However, pharmacokinetic findings from the phase 3 EFECT trial in 2008 prompted researchers to explore a 500-mg dose of fulvestrant.5
The recently published FIRST study is a phase 2, randomized, open-label study comparing fulvestrant 500 mg with anastrozole 1 mg as first-line hormonal therapy for postmenopausal women with hormone receptorpositive advanced breast cancer. Fulvestrant was given 500 mg once monthly with an extra dose given on day 14 of month 1. The trial enrolled 233 patients. The median time to progression was 23.4 months for fulvestrant and 13.1 months for anastrozole. These results translate into a 34% reduction in the risk of progression.6
These outcomes suggest that fulvestrant is as viable and perhaps even preferred first-line therapy for postmenopausal women with hormone receptor-positive, HER2-negative advanced breast cancer. The impressive results from this trial are likely, because the study used the 500-mg dose of fulvestrant, which is twice the dose used in the original trials. However, the 500-mg dose has previously been studied, and long-term outcome data suggest both safety and efficiency. The large randomized, double-blinded phase 3 CONFIRM trial, published in 2013, compared the 250-mg dose with the 500-mg dose and found that the higher dose was associated with a 19% reduction in the risk of death and a 4.1 month increase in median overall survival (OS) without any new safety concerns.5
Palbociclib
The FDA recently granted accelerated approval to palbociclib in combination with letrozole for the first-line therapy of advanced hormone receptor-positive, HER2-negative breast cancer in postmenopausal women. Palbociclib is an oral small-molecular inhibitor of cyclindependent kinases 4 and 6. Preclinical data suggested synergy with anti-estrogen therapies and inhibition of breast cancer cell growth.7
A phase 2, open-label randomized trial (PALOMA-1/TRIO-18) enrolled 165 patients. Progression-free survival (PFS) was 20.2 months for the palbociclib plus letrozole arm and 10.2 months for the letrozole alone arm. Significant toxicities were noted in the palbociclib arm, including 54% of people experiencing grade 3 to 4 neutropenia (vs 1% in the letrozole arm), leukopenia in 19% (vs 0%) and fatigue in 4% (vs 1%). A phase 3 trial is currently enrolling patients.7 While we await the results of the phase 3 trial and long-term follow-up data, palbociclib plus letrozole is a new, viable option for metastatic hormone receptor-positive advanced breast cancer.
Although many practitioners will continue to reasonably use any AI or selective ER modulator when treating metastatic breast cancer, both fulvestrant and palbociclib in combination with letrozole are new evidence-based, first-line options worth considering.
Early-Stage Treatment Options
There are many acceptable therapeutic options for treating early stage breast cancer. Tamoxifen has traditionally been used in the adjuvant setting for premenopausal women, whereas AIs are often used in postmenopausal women. There has also been a long-standing debate about the role of ovarian suppression in premenopausal women.
The recently published phase 3 TEXT and SOFT trials attempted to provide answers to these long-standing therapeutic dilemmas. The SOFT trial randomly assigned 3,066 premenopausal women to 5 years of tamoxifen, 5 years of tamoxifen plus ovarian suppression, or exemestane plus ovarian suppression. The TEXT trial randomly assigned 2,672 women to receive either exemestane plus ovarian suppression or tamoxifen plus ovarian suppression. The studies showed that subjecting all women receiving tamoxifen to ovarian suppression did not provide any significant benefit.8,9
However, the subgroup of women with high-risk disease who required adjuvant chemotherapy and remained premenopausal experienced improved outcomes from ovarian suppression. This high-risk subgroup when given tamoxifen plus ovarian suppression had a 4.5% absolute reduction in breast cancer recurrence at 5 years compared with the group that received tamoxifen alone. When this high-risk subgroup was given exemestane plus ovarian suppression, the women had a 7.7% absolute reduction in breast cancer recurrence at 5 years compared with the group that received tamoxifen alone.8
Ovarian suppression resulted in significant additional AEs, including depression and menopausal symptoms. The authors of the study also pointed out the additional risk of hypertension, musculoskeletal AEs, and decreased bone density. Furthermore, the OS data from these studies are premature, because the patients had fewer AEs than initially anticipated; this resulted in an only 5% mortality at publication.
The study design also raised several interesting questions. The primary endpoint was disease-free survival. The authors defined this as the time from randomization to the first appearance of invasive recurrence of breast cancer (local, regional, or distant), invasive contralateral breast cancer, second (non-breast) invasive cancer, or death without breast cancer recurrence or second invasive cancer. When studying adjuvant therapy for diseases, such as breast cancer, which carry long-term survival, studies often use PFS with various modified definitions as a surrogate marker for OS. Clinicians are then left to decide whether this surrogate marker is an accurate predictor of OS or other important clinical outcomes.
In the combined analysis of the TEXT and SOFT trials, only 60% of the first recurrences, second invasive cancers, or deaths involved recurrence of breast cancer
at a distant site.9 Because locally recurrent breast cancer is highly treatable and often curable, clinicians must ask whether the increased toxicities of ovarian suppression are worth the large number of women who experienced local recurrence given the still relatively small absolute reduction in recurrence risk.
Last, the study authors retrospectively reviewed data from the International Breast Cancer Study Group and U.S. Intergroup trials and concluded that women aged < 35 years were most likely to be at high-risk for AEs.10,11 A subgroup analysis of women aged < 35 years in the SOFT trial noted that breast cancer recurred within 5 years in one-third of women receiving tamoxifen alone, whereas only in one-sixth of women receiving exemestane plus ovarian suppression.8 This is the basis for the conclusion that premenopausal women, particularly those aged < 35 years, with high-risk disease who receive chemotherapy and remain premenopausal after chemotherapy, benefit from ovarian suppression in combination with tamoxifen, and even more impressively from ovarian suppression combined with exemestane.
The problem is that the study did not risk-stratify patients based on those aged < 35 years, and the conclusion is based on a subgroup analysis using a primary endpoint that may not accurately predict OS. Nonetheless, although not definitive, the data from the TEXT and SOFT trials raise interesting therapeutic questions that require further study and certainly provide tempting therapeutic options in patients who are clinically at high risk for recurrence.
HER2-Positive Breast Cancer
Up to 20% of invasive breast cancers are a result of HER2 gene amplification or overexpression of the HER2 protein, a tyrosine kinase transmembrane receptor, resulting in a more aggressive phenotype and a poor prognosis. Anti-HER2 drugs have changed the landscape of the disease previously known as aggressive breast cancer with a poor survival rate.
Treatment with the anti-HER2 humanized monoclonal antibody trastuzumab in addition to chemotherapy, compared with chemotherapy alone, significantly improves PFS and OS among patients with HER2-positive metastatic as well as early breast cancer. However, in most patients with HER2-positive metastatic breast cancer, the disease progresses, highlighting the need for new, targeted therapies for advanced disease.
New Standard of Care
The original studies of trastuzumab showed improved OS in late-stage (metastatic) breast cancer from 20.3 to 25.1 months, and in early-stage breast cancer, it reduced the risk of cancer returning after surgery by an absolute risk of 9.5% and the risk of death by an absolute risk of 3%.
New therapies directed at HER2 are being developed, among them pertuzumab, a humanized monoclonal antibody that binds HER2 at a different epitope of the HER2 extracellular domain (subdomain 2) than that at which trastuzumab binds. Pertuzumab prevents HER2 from dimerizing with other ligand-activated HER receptors, most notably HER3. Like trastuzumab, pertuzumab stimulates antibody-dependent, cell-mediated cytotoxicity. Because pertuzumab and trastuzumab bind to different HER2 epitopes and have complementary mechanisms of action, these 2 agents, when given together, provide a more comprehensive blockade of HER2 signaling and result in greater antitumor activity than does either agent alone in HER2-positive tumor models.12 In phase 2 studies, a pertuzumab–trastuzumab regimen has shown activity in patients with HER2-positive metastatic breast cancer and in patients with early breast cancer.13
In the phase 3 CLEOPATRA study, the combination of pertuzumab plus trastuzumab plus docetaxel, used as first-line treatment for HER2-positive metastatic breast cancer compared with placebo plus trastuzumab plus docetaxel, significantly prolonged PFS (18.5 months vs 12.4 months), with no increase in cardiac toxic effects.12 In a recent updated follow-up of the CLEOPATRA study, the addition of pertuzumab to trastuzumab and docetaxel showed a significantly better median OS (56.5 months vs 40.8 months; hazard ratio, 0.68; P < .001).14 From these results, this combination regimen is now considered a first-line therapy for patients with HER2-positive metastatic breast cancer.
However, the cost of cancer treatment has become a mounting concern during the past decade, as new therapies come down the pipeline with ever-increasing price tags. Trastuzumab costs about $4,500 a month, and the newer pertuzumab runs about 30% higher, at $6,000 a month. For a full course of treatment, the cost of the pertuzumab and trastuzumab combination could go as high as $195,000, depending on the duration of therapy and the choice of taxanes.
Conclusions
The landscape of therapeutic options in high-risk, young patients with early-stage breast cancer as well as patients with advanced or metastatic disease is changing rapidly.
Clinicians now have 2 new first-line options for the treatment of advanced hormone receptor-positive, HER2-negative breast cancer. A phase 3 trial demonstrated that fulvestrant monotherapy offers improved PFS and some improvement in OS compared with anastrazole in postmenopausal women. A phase 2 trial showed that palbociclib plus letrozole offers improved PFS in postmenopausal women. Based on the SOFT and TEXT trials, clinicians treating high-risk premenopausal women now have some data to inform the debate about whether ovarian suppression should be added to hormone therapy.
Based on the CLEOPATRA trial, clinicians can now consider combination pertuzumab and trastuzumab and docetaxel as first-line therapy for patients with HER2-positive metastatic breast cancer.

Treatment for metastatic hormone receptor-positive breast cancer has shifted from traditional cytotoxic chemotherapies to targeted therapeutic options. Most treatment guidelines, including the National Comprehensive Cancer Network guidelines, recommend targeted therapy with AIs or selective ER modulators rather than chemotherapy, except in the case of visceral crisis.3
Until recently, there had been relatively little guidance to inform which hormonal therapy was most appropriate. Aromatase inhibitors were generally reserved for postmenopausal women, whereas tamoxifen was preferred in premenopausal women.
Fulvestrant
The FDA initially approved fulvestrant, a hormone receptor downregulator, in 2002 at a 250-mg dose, following progression on an anti-estrogen therapy, such as tamoxifen in postmenopausal women with stage IV breast cancer. The FDA approval was based on similar response rates for the already approved agent anastrozole.4 However, pharmacokinetic findings from the phase 3 EFECT trial in 2008 prompted researchers to explore a 500-mg dose of fulvestrant.5
The recently published FIRST study is a phase 2, randomized, open-label study comparing fulvestrant 500 mg with anastrozole 1 mg as first-line hormonal therapy for postmenopausal women with hormone receptorpositive advanced breast cancer. Fulvestrant was given 500 mg once monthly with an extra dose given on day 14 of month 1. The trial enrolled 233 patients. The median time to progression was 23.4 months for fulvestrant and 13.1 months for anastrozole. These results translate into a 34% reduction in the risk of progression.6
These outcomes suggest that fulvestrant is as viable and perhaps even preferred first-line therapy for postmenopausal women with hormone receptor-positive, HER2-negative advanced breast cancer. The impressive results from this trial are likely, because the study used the 500-mg dose of fulvestrant, which is twice the dose used in the original trials. However, the 500-mg dose has previously been studied, and long-term outcome data suggest both safety and efficiency. The large randomized, double-blinded phase 3 CONFIRM trial, published in 2013, compared the 250-mg dose with the 500-mg dose and found that the higher dose was associated with a 19% reduction in the risk of death and a 4.1 month increase in median overall survival (OS) without any new safety concerns.5
Palbociclib
The FDA recently granted accelerated approval to palbociclib in combination with letrozole for the first-line therapy of advanced hormone receptor-positive, HER2-negative breast cancer in postmenopausal women. Palbociclib is an oral small-molecular inhibitor of cyclindependent kinases 4 and 6. Preclinical data suggested synergy with anti-estrogen therapies and inhibition of breast cancer cell growth.7
A phase 2, open-label randomized trial (PALOMA-1/TRIO-18) enrolled 165 patients. Progression-free survival (PFS) was 20.2 months for the palbociclib plus letrozole arm and 10.2 months for the letrozole alone arm. Significant toxicities were noted in the palbociclib arm, including 54% of people experiencing grade 3 to 4 neutropenia (vs 1% in the letrozole arm), leukopenia in 19% (vs 0%) and fatigue in 4% (vs 1%). A phase 3 trial is currently enrolling patients.7 While we await the results of the phase 3 trial and long-term follow-up data, palbociclib plus letrozole is a new, viable option for metastatic hormone receptor-positive advanced breast cancer.
Although many practitioners will continue to reasonably use any AI or selective ER modulator when treating metastatic breast cancer, both fulvestrant and palbociclib in combination with letrozole are new evidence-based, first-line options worth considering.
Early-Stage Treatment Options
There are many acceptable therapeutic options for treating early stage breast cancer. Tamoxifen has traditionally been used in the adjuvant setting for premenopausal women, whereas AIs are often used in postmenopausal women. There has also been a long-standing debate about the role of ovarian suppression in premenopausal women.
The recently published phase 3 TEXT and SOFT trials attempted to provide answers to these long-standing therapeutic dilemmas. The SOFT trial randomly assigned 3,066 premenopausal women to 5 years of tamoxifen, 5 years of tamoxifen plus ovarian suppression, or exemestane plus ovarian suppression. The TEXT trial randomly assigned 2,672 women to receive either exemestane plus ovarian suppression or tamoxifen plus ovarian suppression. The studies showed that subjecting all women receiving tamoxifen to ovarian suppression did not provide any significant benefit.8,9
However, the subgroup of women with high-risk disease who required adjuvant chemotherapy and remained premenopausal experienced improved outcomes from ovarian suppression. This high-risk subgroup when given tamoxifen plus ovarian suppression had a 4.5% absolute reduction in breast cancer recurrence at 5 years compared with the group that received tamoxifen alone. When this high-risk subgroup was given exemestane plus ovarian suppression, the women had a 7.7% absolute reduction in breast cancer recurrence at 5 years compared with the group that received tamoxifen alone.8
Ovarian suppression resulted in significant additional AEs, including depression and menopausal symptoms. The authors of the study also pointed out the additional risk of hypertension, musculoskeletal AEs, and decreased bone density. Furthermore, the OS data from these studies are premature, because the patients had fewer AEs than initially anticipated; this resulted in an only 5% mortality at publication.
The study design also raised several interesting questions. The primary endpoint was disease-free survival. The authors defined this as the time from randomization to the first appearance of invasive recurrence of breast cancer (local, regional, or distant), invasive contralateral breast cancer, second (non-breast) invasive cancer, or death without breast cancer recurrence or second invasive cancer. When studying adjuvant therapy for diseases, such as breast cancer, which carry long-term survival, studies often use PFS with various modified definitions as a surrogate marker for OS. Clinicians are then left to decide whether this surrogate marker is an accurate predictor of OS or other important clinical outcomes.
In the combined analysis of the TEXT and SOFT trials, only 60% of the first recurrences, second invasive cancers, or deaths involved recurrence of breast cancer
at a distant site.9 Because locally recurrent breast cancer is highly treatable and often curable, clinicians must ask whether the increased toxicities of ovarian suppression are worth the large number of women who experienced local recurrence given the still relatively small absolute reduction in recurrence risk.
Last, the study authors retrospectively reviewed data from the International Breast Cancer Study Group and U.S. Intergroup trials and concluded that women aged < 35 years were most likely to be at high-risk for AEs.10,11 A subgroup analysis of women aged < 35 years in the SOFT trial noted that breast cancer recurred within 5 years in one-third of women receiving tamoxifen alone, whereas only in one-sixth of women receiving exemestane plus ovarian suppression.8 This is the basis for the conclusion that premenopausal women, particularly those aged < 35 years, with high-risk disease who receive chemotherapy and remain premenopausal after chemotherapy, benefit from ovarian suppression in combination with tamoxifen, and even more impressively from ovarian suppression combined with exemestane.
The problem is that the study did not risk-stratify patients based on those aged < 35 years, and the conclusion is based on a subgroup analysis using a primary endpoint that may not accurately predict OS. Nonetheless, although not definitive, the data from the TEXT and SOFT trials raise interesting therapeutic questions that require further study and certainly provide tempting therapeutic options in patients who are clinically at high risk for recurrence.
HER2-Positive Breast Cancer
Up to 20% of invasive breast cancers are a result of HER2 gene amplification or overexpression of the HER2 protein, a tyrosine kinase transmembrane receptor, resulting in a more aggressive phenotype and a poor prognosis. Anti-HER2 drugs have changed the landscape of the disease previously known as aggressive breast cancer with a poor survival rate.
Treatment with the anti-HER2 humanized monoclonal antibody trastuzumab in addition to chemotherapy, compared with chemotherapy alone, significantly improves PFS and OS among patients with HER2-positive metastatic as well as early breast cancer. However, in most patients with HER2-positive metastatic breast cancer, the disease progresses, highlighting the need for new, targeted therapies for advanced disease.
New Standard of Care
The original studies of trastuzumab showed improved OS in late-stage (metastatic) breast cancer from 20.3 to 25.1 months, and in early-stage breast cancer, it reduced the risk of cancer returning after surgery by an absolute risk of 9.5% and the risk of death by an absolute risk of 3%.
New therapies directed at HER2 are being developed, among them pertuzumab, a humanized monoclonal antibody that binds HER2 at a different epitope of the HER2 extracellular domain (subdomain 2) than that at which trastuzumab binds. Pertuzumab prevents HER2 from dimerizing with other ligand-activated HER receptors, most notably HER3. Like trastuzumab, pertuzumab stimulates antibody-dependent, cell-mediated cytotoxicity. Because pertuzumab and trastuzumab bind to different HER2 epitopes and have complementary mechanisms of action, these 2 agents, when given together, provide a more comprehensive blockade of HER2 signaling and result in greater antitumor activity than does either agent alone in HER2-positive tumor models.12 In phase 2 studies, a pertuzumab–trastuzumab regimen has shown activity in patients with HER2-positive metastatic breast cancer and in patients with early breast cancer.13
In the phase 3 CLEOPATRA study, the combination of pertuzumab plus trastuzumab plus docetaxel, used as first-line treatment for HER2-positive metastatic breast cancer compared with placebo plus trastuzumab plus docetaxel, significantly prolonged PFS (18.5 months vs 12.4 months), with no increase in cardiac toxic effects.12 In a recent updated follow-up of the CLEOPATRA study, the addition of pertuzumab to trastuzumab and docetaxel showed a significantly better median OS (56.5 months vs 40.8 months; hazard ratio, 0.68; P < .001).14 From these results, this combination regimen is now considered a first-line therapy for patients with HER2-positive metastatic breast cancer.
However, the cost of cancer treatment has become a mounting concern during the past decade, as new therapies come down the pipeline with ever-increasing price tags. Trastuzumab costs about $4,500 a month, and the newer pertuzumab runs about 30% higher, at $6,000 a month. For a full course of treatment, the cost of the pertuzumab and trastuzumab combination could go as high as $195,000, depending on the duration of therapy and the choice of taxanes.
Conclusions
The landscape of therapeutic options in high-risk, young patients with early-stage breast cancer as well as patients with advanced or metastatic disease is changing rapidly.
Clinicians now have 2 new first-line options for the treatment of advanced hormone receptor-positive, HER2-negative breast cancer. A phase 3 trial demonstrated that fulvestrant monotherapy offers improved PFS and some improvement in OS compared with anastrazole in postmenopausal women. A phase 2 trial showed that palbociclib plus letrozole offers improved PFS in postmenopausal women. Based on the SOFT and TEXT trials, clinicians treating high-risk premenopausal women now have some data to inform the debate about whether ovarian suppression should be added to hormone therapy.
Based on the CLEOPATRA trial, clinicians can now consider combination pertuzumab and trastuzumab and docetaxel as first-line therapy for patients with HER2-positive metastatic breast cancer.

Psyllium cut frequency of abdominal pain in pediatric IBS trial
Consuming psyllium fiber significantly reduced the frequency, but not the severity, of abdominal pain in children with irritable bowel syndrome in a randomized, double-blind, placebo-controlled trial reported in the May issue of Clinical Gastroenterology and Hepatology (2016 Nov;14[11]:1667).
Psyllium therapy did not reduce the self-reported severity of abdominal pain, Robert J. Shulman, MD, of Baylor College of Medicine in Houston reported with his associates in Clinical Gastroenterology and Hepatology. Psyllium was associated with shifts in intestinal microbiota, compared with baseline, although the changes did not reach statistical significance when compared with placebo, the researchers added. “Further studies are needed to investigate the potential mechanism whereby psyllium decreases abdominal pain frequency in children with irritable bowel syndrome [IBS],” they wrote.
IBS affects up to 20% of school-aged children. Consuming psyllium is thought to improve abdominal pain and stooling symptoms in adults with IBS, but data are inconclusive, and few randomized trials have evaluated fiber in childhood IBS. Therefore, the investigators randomly assigned 103 children (average age, 13 years; standard deviation, 3 years) with IBS who had responded inadequately to an 8-day carbohydrate elimination diet to receive a single daily dose of either psyllium or placebo maltodextrin for 6 weeks. Children aged 7-11 years received 6 g of fiber, while those aged 12-18 years received 12 g of fiber. Patients filled out a daily pain and stool diary during a 2-week baseline assessment period and again during the final 2 weeks of the trial. They also underwent breath hydrogen and methane testing, gut permeability testing, and a stool microbiota assessment during the final weekend of treatment.
At baseline, the trial arms resembled each other in terms of frequency and severity of abdominal pain, psychological characteristics, percentage of normal stools, baseline hydrogen production, and gastrointestinal permeability, the researchers said. During the final 2 weeks of treatment, the psyllium arm reported an average of 8.2 (standard deviation, 1.2) fewer episodes of abdominal pain, compared with baseline, while the control arm reported a mean reduction of 4.1 (SD, 1.3) episodes of abdominal pain (P = .03). At the end of treatment, the arms did not significantly differ in percentage of breath hydrogen or methane production, gastrointestinal permeability, or percentage of normal stools or diarrhea. However, controls had a significantly greater reduction in constipation compared with the psyllium group (P = .048).
Stool microbiome assessments of 33 children revealed a trend toward a greater increase in Bacteroidetes and a greater decrease in Firmicutes bacteria in the fiber group, compared with the control group (P = .068). The fiber group was also “marginally enriched” in bacteria of class Bacteroidia, while the placebo group was enriched in bacteria of class Clostridia (P = .094). However, the groups did not differ at narrower taxonomic levels, the researchers said. A larger sample size might have facilitated better detection of differences between groups, such as in breath hydrogen production or interactions between abdominal pain and psychological symptoms, they added.
The study was supported in part by the National Institutes of Health, the Daffy’s Foundation, and the USDA/ARS. The investigators reported having no conflicts of interest.

Everything We Say and Do: Discussing advance care planning
Editor’s note: “Everything We Say and Do” is an informational series developed by the Society of Hospital Medicine’s Patient Experience Committee to provide readers with thoughtful and actionable communication tactics that have great potential to positively impact patients’ experiences of care. Each article will focus on how the contributor applies one or more of the “key communication” tactics in practice to maintain provider accountability for “everything we say and do that affects our patients’ thoughts, feelings, and well-being.”
What I say and do
I empower all of my patients by giving them the opportunity to consider advance care planning.
Why I do it
Everyone deserves advance care planning, and every health care encounter, including a hospitalization, is an opportunity to better identify and document patients’ wishes for care should they become unable to express them. If we wait for patients to develop serious advanced illness before having advance care planning conversations, we risk depriving them of the care they would want in these situations. Additionally, we place a huge burden on family members who may struggle with excruciatingly difficult decisions in the absence of guidance about their loved one’s wishes.
How I do it
I start by identifying which components of advance care planning each patient needs, using a simple algorithm (see figure). All of my patients are queried about code status, and I give them the opportunity to better understand the value of having a healthcare proxy and advance directives, if they are not already in place.
For the remainder of this column, I’m going to focus on patients who have an acute and/or chronic treatable illness – those who require simpler advance-care-planning conversations.
To comfortably initiate the conversation about advance care planning, I always start by asking permission. I commonly say, “There are a couple of important items I discuss with all of my patients to make sure they get the care they want. Would it be okay for us to talk about those now?” This respectfully puts the patient in control. I then initiate a discussion of code status by saying, “It’s important that all of us on your care team know what you would like us to do if you got so sick that we couldn’t communicate with you. I’m not expecting this to happen, but I ask all my patients this question so that we have your instructions.” From there, the conversation evolves depending on whether the patient has any familiarity with this question and its implications.
To introduce the concept of a health care proxy and advance directives, I ask, “Have you ever thought about who you might choose to make medical decisions on your behalf if you became too sick to make those decisions yourself?” Then, finally, I share the following information, usually referring to the blank advance directives document they received in their admission packet: “There is a valuable way to put your wishes about specific care options in writing so others will know your wishes if you’re unable to communicate with them. Would you like to talk about that right now?” Again, this gives the patient control of the situation and an opportunity to decline the conversation if they are not interested or comfortable at that time.
It’s important to document the nature and outcome of these conversations. Keep in mind, advance care planning discussions need not occur at the time of admission. In fact, admission may be the worst time for some patients, further underscoring the importance of documentation so that subsequent providers can see whether advance care planning has been addressed during the hospital stay.
Note: For useful educational resources that address goals-of-care conversations in patients toward the end of life, the Center to Advance Palliative Care (www.capc.org) has a number of educational courses that address these important communication skills.

Celebrating our accomplishments
I recently had the good fortune to read a commentary written by Dr. Peter Angelos in ACS Surgery News entitled, The Right Choice? Surgeons, confidence, and humility (2017, February, p. 11). The essay touches on the philosophy, psychology, and attitudes that surgeons adopt and express in their daily interactions with the public.
The article refers to “the balance between lack of confidence and overconfidence, and between thoughtful introspection and paralyzing fear of future complications.” This is a critically important struggle in the mind of the surgeon. I would like to propose an exercise to bolster self-esteem in the psyche of the surgeon, particularly in the formative stages of one’s career, without fostering false or pathological bravado.
I certainly see the benefit in this tradition of analyzing and reviewing surgical misadventures and discussing the proper management of uninvited complications. It is a process rooted in the concepts of honesty, transparency, introspection, reflection, collaboration, and trust.
What I would like to propose is not the cessation of the M & M conference, but the addition of a complementary conference, which I refer to as Success and Survival conference. This meeting would showcase clinical scenarios in which a given patient should have succumbed to his illness but, instead, thrived as a result of the exemplary care provided by the surgical team involved. This would shine a bright spotlight on what it is that we do, and why our profession is so extraordinary. It would serve as a wonderful reminder for surgeons at all stages of their careers as to why we chose such a rigorous, challenging, and difficult vocation as our life’s work.
Such a venue would provide young surgeons an opportunity – not to flaunt – but to share and take well-deserved pride in their victories. I believe this conference would be as effective in terms of its educational value as the M & M, but it would not be associated with negative emotions of guilt, shame, and fear. The S & S would be a setting in which the young surgeon could shine in front of his or her peers as well as the attending staff and faculty.
The academic culture that prides itself on adages such as, “Whatever doesn’t kill you makes you stronger,” “The only problem with being on call every other night is that you miss half the pathology,” and “Eat when you can, sleep when you can, and don’t mess with the pancreas,” is long overdue in celebrating the accomplishments of surgeons publicly and on a regular basis
In the end, we should want to promote future generations of surgeons who are technically sound, demonstrate excellent judgment under the most difficult circumstances, and who are able to achieve, ideally, their full surgical potential by arriving at a true harmony between self-assurance and uncertainty.

QI enthusiast turns QI leader
Editor’s note: This new series highlights the professional pathways of quality improvement leaders. This month features the story of Kevin O’Leary, MD, MS, SFHM, chief of hospital medicine at Northwestern University Feinberg School of Medicine in Chicago.
Kevin O’Leary, MD, MS, SFHM, chose a career path in hospital medicine for the reasons that attract many to the specialty – a love of “a little bit of everything, clinically” and the opportunity to problem-solve a diverse range of professional challenges on a daily basis.
“I was frustrated with our internal inefficiencies, and motivated by wanting to provide optimal care to patients,” Dr. O’Leary said, recalling his entry into the world of quality improvement. “It was the first time as a physician that I felt like quality was a problem that I owned – and if anyone was going to address it, it would have to be a hospitalist.”
That epiphany 16 years ago led Dr. O’Leary, now chief of hospital medicine at the same institution, on a path of enacting change. He began volunteering on small improvement projects around the hospital, which led to an invitation to chair the Quality Management Committee in the hospital medicine department. He continued to build his skills by enrolling in Six Sigma training and in Northwestern University’s Master in Healthcare Quality and Patient Safety program.
“That was transformative,” Dr. O’Leary said. “The master’s program, coupled with performance training, changed the trajectory of my career in quality improvement.”
While he encourages anyone with an interest in QI to seek additional training opportunities, he says personal qualities – tenacity, curiosity, and a willingness to collaborate—are better predictors of success. For those wondering how to get started, “look for a niche, an unmet need that is valuable to your organization, and fill it,” he advised. “You don’t have to be an expert in that area, but you can become one.”
Making strong connections within the hospital system is essential. Reach out to the contacts you know, he said, and if they are not the ones to help you solve the problem, they often know who can.
“That’s key to quality improvement success, as well as career success,” he said. “Find a mentor. It might be someone who is more senior within the hospitalist group, in medicine, or even outside the hospital. Meet with them regularly and ask them for feedback on your ideas.”
Newcomers to QI should embrace opportunities to change care and not get discouraged when a project has unintended outcomes.
“Failure is when a team never gets to the point of implementing the intervention or when a team doesn’t know whether the intervention has actually changed results,” he said. “Learning why an intervention isn’t effective can be as valuable as implementing one that is. If every project is successful, it just means that you’re not taking enough risks.”
Dr. O’Leary spends about 25% of his professional time providing clinical care, and another 15% meeting his responsibilities as division chief. He uses the other protected time in his schedule to lead QI and teach QI skills in programs like Northwestern Medicine’s Academy for Quality and Safety Improvement (AQSI).
As a former faculty member in SHM’s Quality and Safety Educator’s Academy (QSEA), he has trained medical educators to develop curricula in quality improvement and patient safety. He says both AQSI and QSEA are especially effective because they encourage interaction, which is valuable to professionals at all levels looking to advance their skill in QI.
“Even in a teaching capacity,” he noted, “what I learned from other faculty and participants in QSEA was critical.”
Residents and junior hospitalists often have the impression that they lack the skills to lead quality initiatives, but Dr. O’Leary says medical school provides the nuts and bolts – analytical skills, statistical knowledge, critical thinking. He encouraged hospitalists to move ahead, even without formal QI training.
“If you have strong interpersonal skills – the willingness to make friends and build connections – you will be successful,” he said.
It’s also an excellent way to learn about the ins and outs of the hospital system and the work of other departments and specialties. Dr. O’Leary especially enjoys that aspect of his work, as well as the ability to address systemic issues that he values.
“I get the greatest fulfillment from the opportunity to be creative … and to implement projects that are important to me and help patients,” he said. “As long as the projects align with organizational goals, I can usually find the support we need to be successful.”

“That was transformative,” Dr. O’Leary said. “The master’s program, coupled with performance training, changed the trajectory of my career in quality improvement.”
While he encourages anyone with an interest in QI to seek additional training opportunities, he says personal qualities – tenacity, curiosity, and a willingness to collaborate—are better predictors of success. For those wondering how to get started, “look for a niche, an unmet need that is valuable to your organization, and fill it,” he advised. “You don’t have to be an expert in that area, but you can become one.”
Making strong connections within the hospital system is essential. Reach out to the contacts you know, he said, and if they are not the ones to help you solve the problem, they often know who can.
“That’s key to quality improvement success, as well as career success,” he said. “Find a mentor. It might be someone who is more senior within the hospitalist group, in medicine, or even outside the hospital. Meet with them regularly and ask them for feedback on your ideas.”
Newcomers to QI should embrace opportunities to change care and not get discouraged when a project has unintended outcomes.
“Failure is when a team never gets to the point of implementing the intervention or when a team doesn’t know whether the intervention has actually changed results,” he said. “Learning why an intervention isn’t effective can be as valuable as implementing one that is. If every project is successful, it just means that you’re not taking enough risks.”
Dr. O’Leary spends about 25% of his professional time providing clinical care, and another 15% meeting his responsibilities as division chief. He uses the other protected time in his schedule to lead QI and teach QI skills in programs like Northwestern Medicine’s Academy for Quality and Safety Improvement (AQSI).
As a former faculty member in SHM’s Quality and Safety Educator’s Academy (QSEA), he has trained medical educators to develop curricula in quality improvement and patient safety. He says both AQSI and QSEA are especially effective because they encourage interaction, which is valuable to professionals at all levels looking to advance their skill in QI.
“Even in a teaching capacity,” he noted, “what I learned from other faculty and participants in QSEA was critical.”
Residents and junior hospitalists often have the impression that they lack the skills to lead quality initiatives, but Dr. O’Leary says medical school provides the nuts and bolts – analytical skills, statistical knowledge, critical thinking. He encouraged hospitalists to move ahead, even without formal QI training.
“If you have strong interpersonal skills – the willingness to make friends and build connections – you will be successful,” he said.
It’s also an excellent way to learn about the ins and outs of the hospital system and the work of other departments and specialties. Dr. O’Leary especially enjoys that aspect of his work, as well as the ability to address systemic issues that he values.
“I get the greatest fulfillment from the opportunity to be creative … and to implement projects that are important to me and help patients,” he said. “As long as the projects align with organizational goals, I can usually find the support we need to be successful.”

Marijuana abuse linked to increased MI risk
Washington – Marijuana abuse was independently associated with an eye-opening doubled risk of acute MI in a large, retrospective, age-matched cohort study, Ahmad Tarek Chami, MD, reported at the annual meeting of the American College of Cardiology.
The link was strongest by far in young adult marijuana abusers, with an adjusted 3.2-fold increased risk of MI in 25- to 29-year-olds with marijuana abuse noted in their medical records, compared with age-matched controls and a 4.56-fold greater risk among the 30- to 34-year-old cannabis abusers, according to Dr. Chami of Case Western Reserve University in Cleveland.
These data constitute a signal warranting further research. Public opinion regarding potheads has undergone a huge shift. Medical and/or recreational marijuana is now legal in 28 states and the District of Columbia. Surveys indicate that, in 2015, 8.3% of Americans aged 12 years and older had used marijuana during the previous month, and 13.5% had used it within the past year.
“Cardiologists and other physicians are more likely than ever before to encounter patients who use marijuana or even ask them to prescribe it,” Dr. Chami said.
The cannabis plant contains more than 60 cannabinoids. Although marijuana is widely prescribed for treatment of nausea, anorexia, neuropathic pain, glaucoma, seizure disorders, and other conditions, the long-term effects of marijuana on the cardiovascular system are largely unknown, he continued.
This ambiguity was the impetus for Dr. Chami’s study. In it, he utilized a database incorporating 26 health care systems across the United States with nearly 50 million patients, which is maintained by Explorys, an 8-year-old Cleveland-based company.
Dr. Chami identified 210,700 patients with cannabis abuse noted in their medical records, covering provider/patient encounters between October 2011 and September 2016. Their mean age was 36.8 years. The abusers were age-matched to 10,395,060 non–marijuana abuser controls.
The 5-year cumulative incidence of MI in this skewed–young patient population was significantly higher than in the marijuana abuser group: 1.28%, compared with 0.89%, for a 44% increase in relative risk.
However, the marijuana abusers also had a significantly higher burden of cardiovascular risk factors than did their non–cannabis abusing counterparts. They were 2.85 times more likely to have hypertension, 1.59 times more likely to be dyslipidemic, and 7.2 times more likely to be cigarette smokers, and they had a 2.8 times greater prevalence of diabetes. Of note, they were also 17.6 times more likely to have been diagnosed with alcohol abuse, and 61 times more likely to abuse cocaine.
In a multivariate analysis adjusted for these and other potential confounders, marijuana abuse remained independently associated with a 1.73-fold increased risk of acute MI. Moreover, after eliminating patients with known coronary artery disease, the strongest risk factor for MI, from the analysis, marijuana abuse was independently associated with a twofold increased risk of MI.
This was a retrospective study, one limitation of which was the standard caveat regarding the possibility of unrecognized confounders that couldn’t be taken into account.
Another study limitation is the uncertainty regarding the diagnosis of “cannabis abuser” in patients’ charts. The Explorys cloud-based database relies on ICD codes to capture data. It doesn’t include specific information on how much marijuana a patient who was labeled as an abuser was actually using. This limitation raises an unanswered question: Were young adults who abused marijuana at highest risk for MI because of heavier use, or are younger patients’ coronary arteries somehow more vulnerable to marijuana’s potential adverse cardiovascular effects?
Several audience members called Dr. Chami’s study “very provocative.” Aaron D. Kugelmass, MD, said that the fundamental question in his mind is whether the cardiovascular hazard of marijuana identified in this study is the result of the practice of smoking the raw product, usually associated with illicit marijuana abusers.
Today, legalized marijuana is often consumed in the form of edible products, tinctures, and other derivatives that don’t involve inhalation of smoke. Whether these alternative forms of consumption pose any cardiovascular risk is an important unresolved issue in this era of widespread decriminalization of cannabis, noted Dr. Kugelmass, chief of cardiology and medical director of the Heart and Vascular Center at Baystate Medical Center in Springfield, Mass.
Dr. Chami reported having no financial conflicts regarding his study.

A Game for All Seasons
Sports and sports figures provide both a welcome relief from the stress of dealing with life and death in the ED and memorable ways of characterizing serious health care issues. When the Institute of Medicine issued its 2006 report “Hospital-Based Emergency Care: At the Breaking Point,” we thought that a quote about a popular restaurant by the late, great New York Yankees catcher Yogi Berra better described the severely overcrowded EDs and ambulance diversion: “Nobody goes there anymore—it’s too crowded.”
In late winter and early spring of this year, after vigorous attempts to repeal/revise the 2010 Affordable Care Act (ACA), a replacement bill was withdrawn immediately prior to a Congressional vote on March 24 due to a lack of support. Seven years earlier, when President Obama also seemed to have little chance of getting the ACA through Congress, we thought that there would be “many more balks before the president and Congress finally pitched a viable health care package to the nation.” Only a month later, however, with the ACA now the law, we suggested that our erroneous prediction was similar to that of “a father who convinces his son to leave for the parking lot during the bottom of the ninth inning of a 3-0 game only to hear the roar of the crowd from the exit ramp as the rookie batter hits a grand-slam home run to win the game.”
In June 2012, when the Supreme Court ruled on the constitutionality of the ACA, many reporters quickly read the Court’s rejection of the first two arguments defending the ACA, and rushed to report that it was dead, without considering that the government had “one more out to go…[the one] casting ACA as a tax—considered to be the weakest player in the lineup—[which] managed to score the winning run to uphold ACA. Game over. Final score: ACA wins 5 to 4.”
But with the 2017 baseball season finally underway, it is a recent football game that provides the perfect paradigm for emergency medicine (EM) and emergency physicians (EPs). The New England Patriots were slight favorites to win Super Bowl 51 over the Atlanta Falcons on February 5,and the first quarter ended with no score. But by halftime, Atlanta was leading 21-3. In 50 years of Super Bowls, no team had ever overcome more than a 10-point deficit to win the game, and with a little over 8 minutes left in the third quarter, the deficit had widened even further to 28-3. Then the Patriots began to turn things around. Though the Patriots never led during regulation play, and no Super Bowl had ever gone into overtime, the fourth quarter ended in a 28-28 tie, and the Patriots went on to win 34-28 in overtime.
Coming out of the locker room to play the second half of that game in front of over 111 million viewers must have been a daunting experience for the Patriots, but no more so than the experience depicted in EP/cinematographer Ryan McGarry’s award-winning documentary “Code Black,” in which he shows young EM residents walking through a packed waiting room to begin their shift, realizing that in the next 12 hours, they could never treat all of the ill patients waiting to be seen. But the young residents proceeded to treat one patient after another without ever giving up or losing their idealism, until in the end, they, too, had won the game against all odds.
Many patients arrive in EDs so ill that there is no reasonable expectation any intervention can save them, but we nevertheless try and sometimes succeed in doing the seemingly impossible. It is the type of medicine we have chosen to devote our careers to, and we are no less heroes than were the Patriots on February 5, 2017. Each time we go out to “play ball” in our overcrowded EDs, it is worth remembering another famous Yogi Berra quote: “It ain’t over till it’s over.”
