Because of physiological changes with aging and differences in cancer biology, caring for older adults (OAs) with cancer requires careful assessment and planning.

Clark Dumontier, MD, of Brigham and Women’s Hospital in Boston, and colleagues sought to define the meaning of the terms “undertreatment” and “overtreatment” for OAs with cancer in a scoping literature review published in the Journal of Clinical Oncology.

Though OAs are typically defined as adults aged 65 years and older, in this review, the authors defined OAs as patients aged 60 years and older.

The authors theorized that a scoping review of papers about this patient population could provide clues about limitations in the oncology literature and guidance about patient management and future research. Despite comprising the majority of cancer patients, OAs are underrepresented in clinical trials.
 

About scoping reviews

Scoping reviews are used to identify existing evidence in a field, clarify concepts or definitions in the literature, survey how research on a topic is conducted, and identify knowledge gaps. In addition, scoping reviews summarize available evidence without answering a discrete research question.

Industry standards for scoping reviews have been established by the Johanna Briggs Institute and Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping reviews. According to these standards, scoping reviews should:

• Establish eligibility criteria with a rationale for each criterion clearly explained
• Search multiple databases in multiple languages
• Include “gray literature,” defined as studies that are unpublished or difficult to locate
• Have several independent reviewers screen titles and abstracts
• Ask multiple independent reviewers to review full text articles
• Present results with charts or diagrams that align with the review’s objective
• Graphically depict the decision process for including/excluding sources
• Identify implications for further research.

In their review, Dr. DuMontier and colleagues fulfilled many of the aforementioned criteria. The team searched three English-language databases for titles and abstracts that included the terms undertreatment and/or overtreatment, and were related to OAs with cancer, inclusive of all types of articles, cancer types, and treatments.

Definitions of undertreatment and overtreatment were extracted, and categories underlying these definitions were derived. Within a random subset of articles, two coauthors independently determined final categories of definitions and independently assigned those categories.
 

Findings and implications

To define OA, Dr. DuMontier and colleagues used a cutoff of 60 years or older. Articles mentioning undertreatment (n = 236), overtreatment (n = 71), or both (n = 51) met criteria for inclusion (n = 256), but only 14 articles (5.5%) explicitly provided formal definitions.

For most of the reviewed articles, the authors judged definitions from the surrounding context. In a random subset of 50 articles, there was a high level of agreement (87.1%; κ = 0.81) between two coauthors in independently assigning categories of definitions.

Undertreatment was applied to therapy that was less than recommended (148 articles; 62.7%) or less than recommended with worse outcomes (88 articles; 37.3%).

Overtreatment most commonly denoted intensive treatment of an OA in whom harms outweighed the benefits of treatment (38 articles; 53.5%) or intensive treatment of a cancer not expected to affect the OA during the patient’s remaining life (33 articles; 46.5%).

Overall, the authors found that undertreatment and overtreatment of OAs with cancer are imprecisely defined concepts. Formal geriatric assessment was recommended in just over half of articles, and only 26.2% recommended formal assessments of age-related vulnerabilities for management. The authors proposed definitions that accounted for both oncologic factors and geriatric domains.
 

Care of individual patients and clinical research

National Comprehensive Cancer Network (NCCN) guidelines for OAs with cancer recommend initial consideration of overall life expectancy. If a patient is a candidate for cancer treatment on that basis, the next recommended assessment is that of the patient’s capacity to understand the relevant information, appreciate the underlying values and overall medical situation, reason through decisions, and communicate a choice that is consistent with the patient’s articulated goals.

In the pretreatment evaluation of OAs in whom there are no concerns about tolerance to antineoplastic therapy, NCCN guidelines suggest geriatric screening with standardized tools and, if abnormal, comprehensive geriatric screening. The guidelines recommend considering alternative treatment options if nonmodifiable abnormalities are identified.

Referral to a geriatric clinical specialist, use of the Cancer and Aging Research Group’s Chemo Toxicity Calculator, and calculation of Chemotherapy Risk Assessment Scale for High-Age Patients score are specifically suggested if high-risk procedures (such as chemotherapy, radiation, or complex surgery, which most oncologists would consider to be “another day in the office”) are contemplated.

The American Society of Clinical Oncology (ASCO) guidelines for geriatric oncology are similarly detailed and endorse similar evaluations and management.

Employing disease-centric and geriatric domains

Dr. DuMontier and colleagues noted that, for OAs with comorbidity or psychosocial challenges, surrogate survival endpoints are unrelated to quality of life (QOL) outcomes. Nonetheless, QOL is valued by OAs at least as much as survival improvement.

Through no fault of their own, the authors’ conclusion that undertreatment and overtreatment are imperfectly defined concepts has a certain neutrality to it. However, the terms undertreatment and overtreatment are commonly used to signify that inappropriate treatment decisions were made. Therefore, the terms are inherently negative and pejorative.

As with most emotionally charged issues in oncology, it is ideal for professionals in our field to take charge when deficiencies exist. ASCO, NCCN, and the authors of this scoping review have provided a conceptual basis for doing so.

An integrated oncologist-geriatrician approach was shown to be effective in the randomized INTEGERATE trial, showing improved QOL, reduced hospital admissions, and reduced early treatment discontinuation from adverse events (ASCO 2020, Abstract 12011).

Therefore, those clinicians who have not formally, systematically, and routinely supplemented the traditional disease-centric endpoints with patient-centered criteria need to do so.

Similarly, a retrospective study published in JAMA Network Open demonstrated that geriatric and surgical comanagement of OAs with cancer was associated with significantly lower 90-day postoperative mortality and receipt of more supportive care services (physical therapy, occupational therapy, speech and swallow rehabilitation, and nutrition services), in comparison with management from the surgical service only.

These clinical and administrative changes will not only enhance patient management but also facilitate the clinical trials required to clarify optimal treatment intensity. As that occurs, we will be able to apply as much precision to the care of OAs with cancer as we do in other areas of cancer treatment.

A global analysis of premature deaths from noncommunicable diseases (NCDs) has shown mixed results for gastrointestinal (GI) cancers.

The data suggest fewer people are dying from stomach cancer, but in some countries, the risk of colorectal cancer death is increasing or declining much more slowly than other causes of premature death.

As for other cancers, in more than half of the countries analyzed, the risk of liver and prostate cancer death is on the rise in men, and the risk of lung cancer death is on the rise in women.

The global decrease in the risk of stomach cancer death may be explained by the fact that stomach cancer’s main cause is Helicobacter pylori infection, which correlates with general food hygiene, the study’s corresponding author Majid Ezzati, PhD, professor of global environmental health at Imperial College London, said in an interview.

“Factors such as more widespread electrification and refrigeration tend to drive the rates down,” he explained.

Dr. Ezzati and colleagues detailed their findings in the second edition of the NCD Countdown 2030 report, recently published in The Lancet.

The report revolves around the Sustainable Development Goal (SDG) target 3.4, which is to reduce premature deaths from NCDs by one-third between 2015 and 2030. The causes of death include cancer, cardiovascular disease, chronic respiratory disease, and diabetes, which are collectively known as NCD4. “Premature” deaths are defined as deaths in people aged 30-70 years.

SDG target 3.4 is still attainable, according to Dr. Ezzati and colleagues. However, their report showed that many countries are falling short of this goal.

The findings come from an analysis of 2016 World Health Organization global estimate data on age-, sex-, and cause-specific mortality for 176 countries and territories with at least 200,000 inhabitants. Mathematical modeling was used to assess the number of approaches countries used to accelerate declines in mortality.
 

Results of the analysis

“Trends in the risk of death from 2010 to 2016 varied considerably among NCD4 causes of death,” Dr. Ezzati and colleagues wrote.

Stomach cancer, ischemic and hemorrhagic stroke, ischemic heart disease, and chronic respiratory diseases had the fastest rates of decline among risks of premature death.

In fact, stomach cancer was the fastest declining cause of death in 45 countries (25.6%) among men and in 40 countries (22.7%) among women.

On the other hand, the risk of premature death from colorectal, liver, breast, prostate, and other cancers declined more slowly than the risk of premature death from other NCDs.

The risk of death from colorectal, liver, and prostate cancers in men and lung cancer in women rose in more than 50% of the countries surveyed.

“The median annual rate of change in the probability of dying prematurely from various causes ranged from +0.2% per year for lung cancer to –2.5% per year for hemorrhagic stroke in women, and from +0.5% per year for colorectal cancer to –1.8% per year for hemorrhagic stroke in men,” the investigators summarized.
 

Explaining the GI cancer results

“There are dramatic differences between the upper and lower GI tract, both in terms of anatomy/embryologic origin but also in terms of exposures,” observed Mark Lewis, MD, medical director of the gastrointestinal oncology program at Intermountain Healthcare in Salt Lake City, in an interview.

H. pylori infection, family history, and diet factor into stomach cancer risk, Dr. Lewis said.

While family history isn’t modifiable, “we are much better now at identifying and eradicating the potentially carcinogenic H. pylori bacterium. In terms of diet, the advent of modern refrigeration has made the prevalence of heavily salted/preserved foods decline,” he added.

A 14-day course of treatment (with a proton pump inhibitor and antibiotics) can eliminate H. pylori, Dr. Lewis continued. “The prophylactic effect against gastric cancer is massive, cutting risk by roughly half,” he said.

At least in the United States, colorectal cancer rates have declined in people 50 years and older, but rates have risen sharply in younger age groups, increasing by 2% annually in the last decade, according to statistics in CA: A Cancer Journal for Clinicians.

“One prevailing theory is prior antibiotic prescriptions [even in childhood] might perturb the microbiome of the lower GI tract and predispose to cancer,” Dr. Lewis said, pointing to a recent study in the British Journal of Cancer that identified an association between repeated antibiotic use and colorectal cancer.
 

Reducing NCD deaths

Dr. Ezzati and colleagues said six high-income countries – Denmark, Luxembourg, New Zealand, Norway, Singapore, and South Korea – are likely to meet SDG target 3.4 if they maintain or exceed average rates of decline seen during 2010-2016. Seventeen countries are on track to reach the target for women, and 15 countries are on track for men.

High-income countries in Asia-Pacific, western Europe, Australasia, and Canada have seen the lowest NCD4 mortality risk, whereas low- and middle-income countries in sub-Saharan Africa and men in central Asia and eastern Europe have seen the highest risk.

“To move forward, we must learn from those countries that are doing well and replicate their strategies to NCD prevention and healthcare,” Dr. Ezzati said in a statement. “Our analysis shows that every country still has options to achieve SDG target 3.4, but they need to address multiple diseases and have strong health systems.”

Increasing access to effective cancer screening and diagnosing and treating cancers earlier could help reduce long-term health consequences and premature deaths from cancer, according to Dr. Ezzati and colleagues. Screening would help even the playing field on cancer diagnosis and survival rates between higher-income countries and low- and middle-income countries.

“This approach will allow earlier diagnosis during precancerous or early stages of disease, followed by treatment of those cancers with effective treatment,” the authors stated.

Tobacco and alcohol interventions and increasing access to quality primary care would also help tamp down on NCD-related deaths.

The authors acknowledged that low-income countries, which may be struggling with other health crises such as COVID-19 and Ebola, may find it a challenge to stage such interventions.

“COVID-19 has exposed how a failure to invest in effective public health to prevent NCDs and provide health care for people living with NCDs can come back to bite us,” said Katie Dain, CEO of the NCD Alliance.

“The good news is that all countries can still meet the 2030 targets, with sound policies and smart investments. NCD prevention and treatment can no longer be seen a ‘nice to have.’ It must be considered as part of pandemic preparedness,” she added.

COVID-19 should serve as an impetus for governments to invest in healthier lifestyle and diet habits and curb alcohol and tobacco use, according to an editorial in The Lancet related to the analysis.

The current report updates 2018’s first NCD Countdown Report, which linked NCD4 conditions to approximately 32 million or 80% of NCD deaths. Unlike the recent report, 2018’s data didn’t focus on specific diseases.

The current report was funded by Research England. Dr. Ezzati received a charitable grant from the AstraZeneca Young Health Programme and personal fees from Prudential and Scor, outside of this report. None of the other authors reported competing interests. Dr. Lewis has no relevant disclosures except that he is a commentator for Medscape, which is owned by the same parent company as MDedge.

A global analysis of premature deaths from noncommunicable diseases (NCDs) has shown mixed results for gastrointestinal (GI) cancers.

The data suggest fewer people are dying from stomach cancer, but in some countries, the risk of colorectal cancer death is increasing or declining much more slowly than other causes of premature death.

As for other cancers, in more than half of the countries analyzed, the risk of liver and prostate cancer death is on the rise in men, and the risk of lung cancer death is on the rise in women.

The global decrease in the risk of stomach cancer death may be explained by the fact that stomach cancer’s main cause is Helicobacter pylori infection, which correlates with general food hygiene, the study’s corresponding author Majid Ezzati, PhD, professor of global environmental health at Imperial College London, said in an interview.

“Factors such as more widespread electrification and refrigeration tend to drive the rates down,” he explained.

Dr. Ezzati and colleagues detailed their findings in the second edition of the NCD Countdown 2030 report, recently published in The Lancet.

The report revolves around the Sustainable Development Goal (SDG) target 3.4, which is to reduce premature deaths from NCDs by one-third between 2015 and 2030. The causes of death include cancer, cardiovascular disease, chronic respiratory disease, and diabetes, which are collectively known as NCD4. “Premature” deaths are defined as deaths in people aged 30-70 years.

SDG target 3.4 is still attainable, according to Dr. Ezzati and colleagues. However, their report showed that many countries are falling short of this goal.

The findings come from an analysis of 2016 World Health Organization global estimate data on age-, sex-, and cause-specific mortality for 176 countries and territories with at least 200,000 inhabitants. Mathematical modeling was used to assess the number of approaches countries used to accelerate declines in mortality.
 

Results of the analysis

“Trends in the risk of death from 2010 to 2016 varied considerably among NCD4 causes of death,” Dr. Ezzati and colleagues wrote.

Stomach cancer, ischemic and hemorrhagic stroke, ischemic heart disease, and chronic respiratory diseases had the fastest rates of decline among risks of premature death.

In fact, stomach cancer was the fastest declining cause of death in 45 countries (25.6%) among men and in 40 countries (22.7%) among women.

On the other hand, the risk of premature death from colorectal, liver, breast, prostate, and other cancers declined more slowly than the risk of premature death from other NCDs.

The risk of death from colorectal, liver, and prostate cancers in men and lung cancer in women rose in more than 50% of the countries surveyed.

“The median annual rate of change in the probability of dying prematurely from various causes ranged from +0.2% per year for lung cancer to –2.5% per year for hemorrhagic stroke in women, and from +0.5% per year for colorectal cancer to –1.8% per year for hemorrhagic stroke in men,” the investigators summarized.
 

Explaining the GI cancer results

“There are dramatic differences between the upper and lower GI tract, both in terms of anatomy/embryologic origin but also in terms of exposures,” observed Mark Lewis, MD, medical director of the gastrointestinal oncology program at Intermountain Healthcare in Salt Lake City, in an interview.

H. pylori infection, family history, and diet factor into stomach cancer risk, Dr. Lewis said.

While family history isn’t modifiable, “we are much better now at identifying and eradicating the potentially carcinogenic H. pylori bacterium. In terms of diet, the advent of modern refrigeration has made the prevalence of heavily salted/preserved foods decline,” he added.

A 14-day course of treatment (with a proton pump inhibitor and antibiotics) can eliminate H. pylori, Dr. Lewis continued. “The prophylactic effect against gastric cancer is massive, cutting risk by roughly half,” he said.

At least in the United States, colorectal cancer rates have declined in people 50 years and older, but rates have risen sharply in younger age groups, increasing by 2% annually in the last decade, according to statistics in CA: A Cancer Journal for Clinicians.

“One prevailing theory is prior antibiotic prescriptions [even in childhood] might perturb the microbiome of the lower GI tract and predispose to cancer,” Dr. Lewis said, pointing to a recent study in the British Journal of Cancer that identified an association between repeated antibiotic use and colorectal cancer.
 

Reducing NCD deaths

Dr. Ezzati and colleagues said six high-income countries – Denmark, Luxembourg, New Zealand, Norway, Singapore, and South Korea – are likely to meet SDG target 3.4 if they maintain or exceed average rates of decline seen during 2010-2016. Seventeen countries are on track to reach the target for women, and 15 countries are on track for men.

High-income countries in Asia-Pacific, western Europe, Australasia, and Canada have seen the lowest NCD4 mortality risk, whereas low- and middle-income countries in sub-Saharan Africa and men in central Asia and eastern Europe have seen the highest risk.

“To move forward, we must learn from those countries that are doing well and replicate their strategies to NCD prevention and healthcare,” Dr. Ezzati said in a statement. “Our analysis shows that every country still has options to achieve SDG target 3.4, but they need to address multiple diseases and have strong health systems.”

Increasing access to effective cancer screening and diagnosing and treating cancers earlier could help reduce long-term health consequences and premature deaths from cancer, according to Dr. Ezzati and colleagues. Screening would help even the playing field on cancer diagnosis and survival rates between higher-income countries and low- and middle-income countries.

“This approach will allow earlier diagnosis during precancerous or early stages of disease, followed by treatment of those cancers with effective treatment,” the authors stated.

Tobacco and alcohol interventions and increasing access to quality primary care would also help tamp down on NCD-related deaths.

The authors acknowledged that low-income countries, which may be struggling with other health crises such as COVID-19 and Ebola, may find it a challenge to stage such interventions.

“COVID-19 has exposed how a failure to invest in effective public health to prevent NCDs and provide health care for people living with NCDs can come back to bite us,” said Katie Dain, CEO of the NCD Alliance.

“The good news is that all countries can still meet the 2030 targets, with sound policies and smart investments. NCD prevention and treatment can no longer be seen a ‘nice to have.’ It must be considered as part of pandemic preparedness,” she added.

COVID-19 should serve as an impetus for governments to invest in healthier lifestyle and diet habits and curb alcohol and tobacco use, according to an editorial in The Lancet related to the analysis.

The current report updates 2018’s first NCD Countdown Report, which linked NCD4 conditions to approximately 32 million or 80% of NCD deaths. Unlike the recent report, 2018’s data didn’t focus on specific diseases.

Prognoses for patients with AIDS-associated, non-Hodgkin lymphomas (AIDS-NHLs) have improved dramatically as HIV/AIDS has become easier to treat, and “we’re actually seeing patients with long-term remissions that are translating to cure,” a hematologist told colleagues at the virtual 2020 annual meeting of the Association of VA Hematology/Oncology (AVAHO).

“Even those with low CD4 counts initially have more chance of survival compared to the historic patients in the pre-HAART [highly active antiretroviral therapy] era,” explained Erin Reid, MD, MS, of the University of California at San Diego Moores Cancer Center. “They’re seeing complete-response rates and overall-survival rates that are nearly matching what we’re seeing in the non-HIV lymphoma cases. And aggressive infection prophylaxis has seemed to mitigate some of the infectious complications.”

Still, Reid said, a severe form of AIDS-NHL continues to have very poor outcomes, although specific regimens appear to be brightening the picture somewhat.

According to Dr. Reid, AIDS-NHLs are the most common malignancy in the HIV-positive population, and patients with these cancers are more likely to have aggressive lymphomas. These patients are also more likely to have lymphomas associated with Epstein-Barr virus—40 to 80%, depending on the subtype of lymphoma—and Kaposi sarcoma-associated herpesvirus (also known as human herpesvirus-8, or HHV8).

“These viruses are driving these cancers, and it begs the question of whether there’s something we can do to target these viruses within these cancer cells in a way that’s therapeutic,” she said.

Compared with the non-HIV population, patients with AIDS-NHL “are much more likely to present with advanced stage, extranodal disease and central nervous system involvement,” she said.

HAART Benefits

It’s become clear that HIV control via HAART has benefits in terms of higher tolerance of chemotherapy doses—“we’re able to use more full or traditional dose regimens”—and perhaps cancer suppression too, she said. A 2013 meta-analysis “favored concurrent therapy with chemotherapy [and HAART]. This has become our recommended standard of care for virtually all cases, except the very rare ones where you cannot find a regimen that is compatible from a PK [pharmacokinetics] standpoint.”

Reid also noted that the HAART era has changed the role of CD4 counts in AIDS-NHLs. “While CD4 count still has some predictive value, its impact on mortality appears attenuated,” she said.

EPOCH Treatment

With regard to treatment, she emphasized the importance of HAART: “We would recommend concurrent HAART whenever possible with chemotherapy, or start it immediately afterward.”

Aggressive infection prophylaxis also is recommended through granulocyte colony-stimulating factor and agents to target threats from pneumocystis jiroveci pneumonia, gram negative rods, and varicella-zoster virus. “I’ve moved away from fungal prophylaxis over the years, only dealing with it if there’s a known fungal infection,” she said.

As for treatment of AIDS-NHL, Reid Suggested that research supports the EPOCH regimen --etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin. However, “we still need strategies for refractory and relapsed disease,” she said.

Reid noted that she has started to see more plasmablastic cases, although her experience is anecdotal. Plasmablastic lymphoma is much more common in the HIV-positive setting, she said.

Lifespans are poor for these patients, with many failing to live for a year. But research hints that the prognosis in AIDS-NHL patients on HAART may actually be better than in the non-HIV population, she said.

A trial published in September 2020, in fact, reports that 87% of 15 patients with AIDS-associated plasmablastic lymphoma survived for at least one year on the EPOCH regimen. Overall, the study found that “people with a collection of HIV-associated lymphomas were doing well overall with the EPOCH backbone,” Reid explained.

Reid reported no relevant disclosures.

Although it may seem that veterans would have a very low risk of bleeding disorders since they were medically cleared for military service, a hematologist/oncologist cautioned that veterans might indeed suffer from both inherited and noninherited forms of these conditions. At the virtual 2020 annual meeting of the Association of VA Hematology/Oncology (AVAHO) Bethany Samuelson Bannow, MD, of Oregon Health & Science University’s Knight Cancer Institute urged colleagues to understand the diagnosis and treatment of bleeding disorders.

            “Most importantly, even though these are patients you probably don’t see on a regular basis, you are never alone,” since colleagues are available to help, she said. Samuelson Bannow treats patients at US Department of Veterans Affairs (VA) Portland Health Care System and used her presentation to focus on 4 types of bleeding disorders. A summary of her perspective and recommendations follows.

Acquired hemophilia: Watch for Infections

Acquired hemophilia affects only an estimated 1.3 to 1.5 in 1 million people, but VA physicians may see it more often since it affects an older population (median age is 78 years), Samuelson Bannow said. “I’ve seen about 4 cases in the last 2 years,” she said. “I’m not sure if we’re a magnet, but it does come up.”

The diagnosis is based on laboratory findings, and a lack of personal or family history of coagulopathy is key, she said. Twenty percent or more of patients older than 65 years die from the disorder, but bleeding usually isn’t the cause. Instead, patients tend to die from infections, she said.

Initial treatment must focus on stopping the bleeding, she said. The new drug porcine antihemophilic factor (recombinant)—Obizur—“is very helpful” and is Samuelson Bannow’s first choice, but it may not widely available at all VA medical centers. Recombinant FVIIa (NovoSeven) and activated prothrombin complex concentrate (Feiba) also are options.

            “The goal is to overpower the clotting cascade and get that burst of thrombin generation that you need to get the bleeding under control. Titrate to the amount of bleeding the patient is having, and make sure you’re doing local control as well,” Samuelson Bannow said. She added that the 2 agents may not work depending on the patient. Neither is preferred and both may be appropriate. “There’s no real reason to pick one over the other beyond convenience and availability.”

            There’s another “equally important component of management,” she said: Inhibitor eradication. “The only way to do this is with immune suppression. You’re going to have to suppress the immune system to get rid of the inhibitor. That’s why we see such high rates of death because we have to use heavy-hitter immunosuppressants.”

            Treatment options include steroids and cyclophosphamide (a common first-line option), rituximab, calcineurin inhibitors, and mycophenolate mofetil. “Just be aware that there is an increased risk of infection with these agents,” she said. “You want to see a decrease in the titer of your inhibitor. This can take 3 or more weeks, and it can take longer for it to disappear entirely. Look for normalized factor VIII level and absent inhibitor.”

            She added: “I tend to do a slow taper, one agent at a time, over the course of weeks. If you see a return of the inhibitor, you can ramp back up as needed. Continue to monitor for a year or more since patients are at high risk of recurrence.”

Acquired von Willebrand Syndrome: Fix the Associated Conditions

Acquired von Willebrand Syndrome is another rare bleeding disorder that may appear in veterans “since it’s associated with a lot of conditions that we see in the VA,” such as heart disorders, solid tumors, vascular malformations, and lymphoproliferative and myeloproliferative disorders, Samuelson Bannow said.

            As with acquired hemophilia, the key is to focus on controlling the bleeding, she said. Then, she advised, focus on the associated condition: “Correct the underlying disorder: Treat the malignancy, address the [cardiac] shear stress, correct hypothyroidism, correct the cardiac defects.”

Inherited Hemophilia: Don’t Rule It Out

It’s possible to “sneak through” military medical screening with undiagnosed inherited bleeding disorders, Dr. Samuelson Bannow said. That’s because service members may have never had an injury that triggered abnormal bleeding, she said. “You can see how someone could slip into the military with a [low clotting factor level]. The classic presentation is going to be joint bleeds and abnormalities. These can be traumatic and spontaneous without any kind of an injury,” she said.

            A general rule for these patients is to “replace what’s missing, and 100% is always normal.” The 100% refers to clotting factor level. She recommended reviewing 2013 guidelines for the treatment of the disorder.

Inherited von Willebrand Syndrome: Ask About Tonsillectomies

Inherited von Willebrand Syndrome is more common in women than it is in men. Bleeding “will primarily be mucocutaneous and trauma-induced,” said. Samuelson Bannow. She recommended asking patients if they have had a tonsillectomy and, if so, did they suffer from unusual bleeding. “If they did not have excessive bleeding, it’s a pretty good sign their hemostasis is good.”

            She recommends a nasal spray drug called desmopressin (DDAVP, Stimate) for management. “It’s critical to know that you must test for efficacy first,” she said. “One of the most common mistakes that people make is that they may give patients DDAVP before surgery without knowing if it works or not. It doesn’t work for every patient.” She typically avoids this drug in patients aged > 65 years, or even > 60 years, due to increased thrombosis risk.

            Recombinant von Willebrand factor (Vonvendi) is a “very helpful drug at patients at increased risk of thrombosis,” she said. However, she noted that the drug, at last check, is not on the VA’s formulary.

            At the end of her presentation, Samuelson Bannow urged colleagues to contact specialized Hemophilia Treatment Centers (HTCs) near them: “Follow this link, find an HTC [Hemophilia Treatment Center] near you, and create a partnership.”

Samuelson Bannow reported no relevant disclosures.

            Treatment options include steroids and cyclophosphamide (a common first-line option), rituximab, calcineurin inhibitors, and mycophenolate mofetil. “Just be aware that there is an increased risk of infection with these agents,” she said. “You want to see a decrease in the titer of your inhibitor. This can take 3 or more weeks, and it can take longer for it to disappear entirely. Look for normalized factor VIII level and absent inhibitor.”

            She added: “I tend to do a slow taper, one agent at a time, over the course of weeks. If you see a return of the inhibitor, you can ramp back up as needed. Continue to monitor for a year or more since patients are at high risk of recurrence.”

Acquired von Willebrand Syndrome: Fix the Associated Conditions

Acquired von Willebrand Syndrome is another rare bleeding disorder that may appear in veterans “since it’s associated with a lot of conditions that we see in the VA,” such as heart disorders, solid tumors, vascular malformations, and lymphoproliferative and myeloproliferative disorders, Samuelson Bannow said.

            As with acquired hemophilia, the key is to focus on controlling the bleeding, she said. Then, she advised, focus on the associated condition: “Correct the underlying disorder: Treat the malignancy, address the [cardiac] shear stress, correct hypothyroidism, correct the cardiac defects.”

Inherited Hemophilia: Don’t Rule It Out

It’s possible to “sneak through” military medical screening with undiagnosed inherited bleeding disorders, Dr. Samuelson Bannow said. That’s because service members may have never had an injury that triggered abnormal bleeding, she said. “You can see how someone could slip into the military with a [low clotting factor level]. The classic presentation is going to be joint bleeds and abnormalities. These can be traumatic and spontaneous without any kind of an injury,” she said.

            A general rule for these patients is to “replace what’s missing, and 100% is always normal.” The 100% refers to clotting factor level. She recommended reviewing 2013 guidelines for the treatment of the disorder.

Inherited von Willebrand Syndrome: Ask About Tonsillectomies

Inherited von Willebrand Syndrome is more common in women than it is in men. Bleeding “will primarily be mucocutaneous and trauma-induced,” said. Samuelson Bannow. She recommended asking patients if they have had a tonsillectomy and, if so, did they suffer from unusual bleeding. “If they did not have excessive bleeding, it’s a pretty good sign their hemostasis is good.”

            She recommends a nasal spray drug called desmopressin (DDAVP, Stimate) for management. “It’s critical to know that you must test for efficacy first,” she said. “One of the most common mistakes that people make is that they may give patients DDAVP before surgery without knowing if it works or not. It doesn’t work for every patient.” She typically avoids this drug in patients aged > 65 years, or even > 60 years, due to increased thrombosis risk.

            Recombinant von Willebrand factor (Vonvendi) is a “very helpful drug at patients at increased risk of thrombosis,” she said. However, she noted that the drug, at last check, is not on the VA’s formulary.

            At the end of her presentation, Samuelson Bannow urged colleagues to contact specialized Hemophilia Treatment Centers (HTCs) near them: “Follow this link, find an HTC [Hemophilia Treatment Center] near you, and create a partnership.”

Samuelson Bannow reported no relevant disclosures.

Two new protein biomarkers may serve as prognostic indicators for outcomes in chronic lymphocytic leukemia (CLL) patients, according to the results of a proteomic assessment of patients’ serum compared to their event-free survival (EFS).

The results were published in Experimental Hematology.

The study attempted to validate the prognostic ability of known proteomic markers measured pretreatment and to search for new proteomic markers that might be related to treatment response in CLL, according to Fatemeh Saberi Hosnijeh, MD, of Erasmus MC, University Medical Center, Rotterdam, The Netherlands, and colleagues.

Baseline serum samples were taken from 51 CLL patients who were then treated with chemoimmunotherapy. The samples were analyzed for 360 proteomic markers, and those results were compared with patient EFS.

Study subjects were selected from patients enrolled in the HOVON 109 clinical trial, a phase 1/2 trial designed to assess the efficacy and safety of first-line therapy involving chlorambucil, rituximab,and lenalidomide in elderly patients and young frail patients with advanced CLL.

The patients assessed comprised 30 men and 21 women, and the median EFS for all patients was 23 months (ranging from 1.25 to 60.9 months).
 

Promising biomarkers

The researchers found that patients who had high serum levels of the proteins sCD23 (P = .026), sCD27 (P = .04), the serine peptidase inhibitor SPINT1 (P = .001), and the surface antigen protein LY9 (P = .0003) had a shorter EFS than those with marker levels below the median.

“Taken together, our results validate the prognostic impact of sCD23 and highlight SPINT1 and LY9 as possible promising markers for treatment response in CLL patients,” the researchers stated.

“Despite the relatively small number of available cases, which had an impact on statistical power, our pilot study identified SPINT1 and LY9 as promising independent prognostic proteomic markers next to sCD23 and sCD27 in patients treated for CLL. Further studies with larger sample sizes are required to validate these results,” the researchers concluded.

This research was supported by a grant from Gilead Sciences and an EU TRANSCAN/Dutch Cancer Society grant. The authors declared that they had no conflicts of interest.

First-line lorlatinib significantly prolonged progression-free survival (PFS) when compared with crizotinib in advanced ALK-positive non–small cell lung cancer (NSCLC), according to an interim analysis of the phase 3 CROWN trial.

Lorlatinib also produced a higher overall and intracranial response rate, prolonging progression to CNS disease.

These findings “support the use of lorlatinib as a highly effective first-line therapy for patients with advanced ALK-positive NSCLC,” said Benjamin Solomon, MBBS, PhD, of the Peter MacCallum Cancer Centre in Melbourne.

“The CROWN study clearly establishes lorlatinib as another option” among other first-line ALK inhibitors, Dr. Solomon said when presenting the findings at the European Society for Medical Oncology Virtual Congress 2020.

“We now have multiple options for first-line treatment of patients with ALK-positive lung cancer,” noted study discussant Christine Lovly, MD, PhD, a medical oncologist and associate professor at Vanderbilt University Medical Center in Nashville, Tenn.

The question now, she said, is how to choose among these options. The drugs have all bested crizotinib in trials but haven’t gone head to head against one another.
 

Lorlatinib and CROWN

Lorlatinib is currently approved in the United States to treat ALK-positive metastatic NSCLC that has progressed on crizotinib and at least one other ALK inhibitor. Lorlatinib was granted accelerated approval for this indication based on response rate and duration.

The CROWN study was intended to support the conversion to full approval, according to Pfizer, which is developing both lorlatinib and crizotinib. Pfizer also plans to use the results of CROWN to seek a first-line indication for lorlatinib in NSCLC.

CROWN enrolled 296 patients with stage IIIB/IV ALK-positive NSCLC who had received no prior systemic treatment. Patients with asymptomatic treated or untreated CNS metastases were eligible.

There were 149 patients randomized to lorlatinib at 100 mg daily and 147 randomized to crizotinib at 250 mg twice daily. Five patients in the crizotinib arm were included in the analysis but were not treated, Dr. Solomon said.

The median age was 61 years in the lorlatinib arm and 56 years in the crizotinib arm. Nearly all patients were White (48% in the lorlatinib arm and 49% in the crizotinib arm) or Asian (44% in both arms). A majority of patients were women (56% in the lorlatinib arm and 62% in the crizotinib arm), and more than half said they never smoked (54% in the lorlatinib arm and 64% in the crizotinib arm).
 

Response and PFS

According to blinded independent central review, the objective response rate was 76% with lorlatinib (113/149) and 58% with crizotinib (85/147). There were four complete responses with lorlatinib and none with crizotinib.

Among patients who had measurable or nonmeasurable brain metastases at baseline, the intracranial ORR was 66% with lorlatinib (25/38) and 20% (8/40) with crizotinib. In patients with only measurable brain metastases at baseline, the intracranial ORR was 82% with lorlatinib (14/17) and 23% with crizotinib (3/13).

The 12-month PFS rate was 78% in the lorlatinib arm and 39% in the crizotinib arm. The median PFS was 9.3 months in the crizotinib arm but was not reached in the lorlatinib arm, which “corresponded to a 72% reduction in the risk of death or progression [hazard ratio, 0.21; P < .001],” Dr. Solomon said.

“[T]he PFS for alectinib in the first line is approximately 3 years,” Dr. Lovly noted. “We anxiously await additional data for lorlatinib to see how long the PFS will be.”

The median time to intracranial progression was 16.6 months in the crizotinib arm but was not reached in the lorlatinib arm (HR, 0.07; P < .001).

“These data indicate the ability of lorlatinib not only to delay the progression of existing brain metastases, but also to prevent the development of new brain metastases,” Dr. Solomon said.

Dr. Lovly noted that the efficacy of lorlatinib in the brain is “quite compelling,” but other ALK inhibitors have demonstrated similar results.

As for overall survival, the data are still immature. The median overall survival was not reached with lorlatinib or crizotinib (HR, 0.72).
 

Toxicity

Dr. Solomon noted that lorlatinib “does have a different toxicity profile, compared to other ALK inhibitors.” Specifically, lorlatinib is associated with hypercholesterolemia and hypertriglyceridemia, which have not been seen with other ALK inhibitors.

Lorlatinib is also associated with neurocognitive problems, including inattention, memory impairment, and mild confusion. Mood effects include emotional lability – “someone watching a movie might burst into tears when they wouldn’t have otherwise,” Dr. Solomon said – as well as anxiety and depression.

“So it’s important to tell not just the patient but their family about these things so that they identify when [the events] happen,” Dr. Solomon said. “That’s key because [the events are] completely reversible when you stop the drug. With dose interruption, those effects will resolve.”

Other adverse events that were more common with lorlatinib (a 10% or greater difference in frequency from crizotinib) included edema, weight gain, and peripheral neuropathy. Diarrhea, nausea, fatigue, vision disorders, constipation, and increased liver enzymes were more common with crizotinib. Grade 3-4 adverse events led to discontinuation in fewer than 10% of patients in each arm.

The study was funded by Pfizer, and the investigators included employees. Dr. Solomon is an adviser for Pfizer and other companies, and Dr. Lovly’s industry ties included being both an advisor and speaker for Pfizer.

An international survey provides new insights into how COVID-19 has affected, and may continue to affect, the field of oncology.

The survey showed that “COVID-19 has had a major impact on the organization of patient care, on the well-being of caregivers, on continued medical education, and on clinical trial activities in oncology,” stated Guy Jerusalem, MD, PhD, of Centre Hospitalier Universitaire de Liège (Belgium).

Dr. Jerusalem presented these findings at the European Society for Medical Oncology Virtual Congress 2020.

The survey was distributed by 20 oncologists from 10 of the countries most affected by COVID-19. Responses were obtained from 109 oncologists representing centers in 18 countries. The responses were recorded between June 17 and July 14, 2020.

The survey consisted of 95 items intended to evaluate the impact of COVID-19 on the organization of oncologic care. Questions encompassed the capacity and service offered at each center, the magnitude of COVID-19–based care interruptions and the reasons for them, the ensuing challenges faced, interventions implemented, and the estimated harms to patients during the pandemic.

The 109 oncologists surveyed had a median of 20 years of oncology experience. A majority of respondents were men (61.5%), and the median age was 48.5 years.

The respondents had worked predominantly (62.4%) at academic hospitals, with 29.6% at community hospitals. Most respondents worked at general hospitals with an oncology unit (66.1%) rather than a specialized separate cancer center (32.1%).

The most common specialty was breast cancer (60.6%), followed by gastrointestinal cancer (10.1%), urogenital cancer (9.2%), and lung cancer (8.3%).
 

Impact on treatment

The treatment modalities affected by the pandemic – through cancellations or delays in more than 10% of patients – included surgery (in 34% of centers), chemotherapy (22%), radiotherapy (13.7%), checkpoint inhibitor therapy (9.1%), monoclonal antibodies (9%), and oral targeted therapy (3.7%).

Among oncologists treating breast cancer, cancellations/delays in more than 10% of patients were reported for everolimus (18%), CDK4/6 inhibitors (8.9%), and endocrine therapy (2.2%).

Overall, 34.8% of respondents reported increased use of granulocyte colony–stimulating factor, and 6.4% reported increased use of erythropoietin.

On the other hand, 11.1% of respondents reported a decrease in the use of double immunotherapy, and 21.9% reported decreased use of corticosteroids.

Not only can the immunosuppressive effects of steroid use increase infection risks, Dr. Jerusalem noted, fever suppression can lead to a delayed diagnosis of COVID-19.

“To circumvent potential higher infection risks or greater disease severity, we use lower doses of steroids, but this is not based on studies,” he said.

“Previous exposure to steroids or being on steroids at the time of COVID-19 infection is a detrimental factor for complications and mortality,” commented ESMO President Solange Peters, MD, PhD, of Centre Hospitalier Universitaire Vaudois in Lausanne, Switzerland.

Frontline Medical News

Dr. Peters noted that the observation was based on lung cancer registry findings. Furthermore, because data from smaller outbreaks of other coronavirus infections suggested worse prognosis and increased mortality, steroid use was already feared in the very early days of the COVID-19 pandemic.

Lastly, earlier cessation of palliative treatment was observed in 32.1% of centers, and 64.2% of respondents agreed that undertreatment because of COVID-19 is a major concern.

Dr. Jerusalem noted that the survey data do not explain the early cessation of palliative treatment. “I suspect that many patients died at home rather than alone in institutions because it was the only way they could die with their families around them.”
 

Telehealth, meetings, and trials

The survey also revealed rationales for the use of teleconsultation, including follow-up (94.5%), oral therapy (92.7%), immunotherapy (57.8%), and chemotherapy (55%).

Most respondents reported more frequent use of virtual meetings for continuing medical education (94%), oncologic team meetings (92%), and tumor boards (82%).

While about 82% of respondents said they were likely to continue the use of telemedicine, 45% said virtual conferences are not an acceptable alternative to live international conferences such as ESMO, Dr. Jerusalem said.

Finally, nearly three-quarters of respondents (72.5%) said all clinical trial activities are or will soon be activated, or never stopped, at their centers. On the other hand, 27.5% of respondents reported that their centers had major protocol violations or deviations, and 37% of respondents said they expect significant reductions in clinical trial activities this year.

Dr. Jerusalem concluded that COVID-19 is having a major, long-term impact on the organization of patient care, caregivers, continued medical education, and clinical trial activities in oncology.

An international survey provides new insights into how COVID-19 has affected, and may continue to affect, the field of oncology.

The survey showed that “COVID-19 has had a major impact on the organization of patient care, on the well-being of caregivers, on continued medical education, and on clinical trial activities in oncology,” stated Guy Jerusalem, MD, PhD, of Centre Hospitalier Universitaire de Liège (Belgium).

Dr. Jerusalem presented these findings at the European Society for Medical Oncology Virtual Congress 2020.

The survey was distributed by 20 oncologists from 10 of the countries most affected by COVID-19. Responses were obtained from 109 oncologists representing centers in 18 countries. The responses were recorded between June 17 and July 14, 2020.

The survey consisted of 95 items intended to evaluate the impact of COVID-19 on the organization of oncologic care. Questions encompassed the capacity and service offered at each center, the magnitude of COVID-19–based care interruptions and the reasons for them, the ensuing challenges faced, interventions implemented, and the estimated harms to patients during the pandemic.

The 109 oncologists surveyed had a median of 20 years of oncology experience. A majority of respondents were men (61.5%), and the median age was 48.5 years.

The respondents had worked predominantly (62.4%) at academic hospitals, with 29.6% at community hospitals. Most respondents worked at general hospitals with an oncology unit (66.1%) rather than a specialized separate cancer center (32.1%).

The most common specialty was breast cancer (60.6%), followed by gastrointestinal cancer (10.1%), urogenital cancer (9.2%), and lung cancer (8.3%).
 

Impact on treatment

The treatment modalities affected by the pandemic – through cancellations or delays in more than 10% of patients – included surgery (in 34% of centers), chemotherapy (22%), radiotherapy (13.7%), checkpoint inhibitor therapy (9.1%), monoclonal antibodies (9%), and oral targeted therapy (3.7%).

Among oncologists treating breast cancer, cancellations/delays in more than 10% of patients were reported for everolimus (18%), CDK4/6 inhibitors (8.9%), and endocrine therapy (2.2%).

Overall, 34.8% of respondents reported increased use of granulocyte colony–stimulating factor, and 6.4% reported increased use of erythropoietin.

On the other hand, 11.1% of respondents reported a decrease in the use of double immunotherapy, and 21.9% reported decreased use of corticosteroids.

Not only can the immunosuppressive effects of steroid use increase infection risks, Dr. Jerusalem noted, fever suppression can lead to a delayed diagnosis of COVID-19.

“To circumvent potential higher infection risks or greater disease severity, we use lower doses of steroids, but this is not based on studies,” he said.

“Previous exposure to steroids or being on steroids at the time of COVID-19 infection is a detrimental factor for complications and mortality,” commented ESMO President Solange Peters, MD, PhD, of Centre Hospitalier Universitaire Vaudois in Lausanne, Switzerland.

Dr. Peters noted that the observation was based on lung cancer registry findings. Furthermore, because data from smaller outbreaks of other coronavirus infections suggested worse prognosis and increased mortality, steroid use was already feared in the very early days of the COVID-19 pandemic.

Lastly, earlier cessation of palliative treatment was observed in 32.1% of centers, and 64.2% of respondents agreed that undertreatment because of COVID-19 is a major concern.

Dr. Jerusalem noted that the survey data do not explain the early cessation of palliative treatment. “I suspect that many patients died at home rather than alone in institutions because it was the only way they could die with their families around them.”
 

Telehealth, meetings, and trials

The survey also revealed rationales for the use of teleconsultation, including follow-up (94.5%), oral therapy (92.7%), immunotherapy (57.8%), and chemotherapy (55%).

Most respondents reported more frequent use of virtual meetings for continuing medical education (94%), oncologic team meetings (92%), and tumor boards (82%).

While about 82% of respondents said they were likely to continue the use of telemedicine, 45% said virtual conferences are not an acceptable alternative to live international conferences such as ESMO, Dr. Jerusalem said.

Finally, nearly three-quarters of respondents (72.5%) said all clinical trial activities are or will soon be activated, or never stopped, at their centers. On the other hand, 27.5% of respondents reported that their centers had major protocol violations or deviations, and 37% of respondents said they expect significant reductions in clinical trial activities this year.

Dr. Jerusalem concluded that COVID-19 is having a major, long-term impact on the organization of patient care, caregivers, continued medical education, and clinical trial activities in oncology.

He cautioned that “the risk of a delayed diagnosis of new cancers and economic consequences of COVID-19 on access to health care and cancer treatments have to be carefully evaluated.”

One year into the implementation of the Mission Act, the US Department of Veterans Affairs (VA) continues to expand a wide-ranging third-party-administered program to boost the access of veterans to the civilian medical system, a VA official told colleagues at the virtual 2020 annual meeting of the Association of VA Hematology/Oncology (AVAHO). “VA has given to the third-party administrators what they do well, which is payment of claims, and VA has taken back what we think we can do better—scheduling, care coordination, and customer service,” said Elizabeth Brill, MD, MBA, chief medical officer and senior adviser to the acting assistant undersecretary for Health for Community Care.

            The 2 third-party contractors that run the Community Care Network (CCN) are Optum and TriWest. Both companies now proces patients at all VA medical facilities in the continental US. Optum serves all the states that are entirely (or mainly) in the Central and Eastern Time Zones—except for Texas—plus Puerto Rico, Washington D.C., and the US Virgin Islands. TriWest serves Texas, Hawaii, and the states that are entirely (or mainly) in the Mountain and Pacific Time Zones. The VA has not yet assigned any contractor for Alaska, Guam, American Samoa, and the Northern Mariana Islands.

“We have tried to consolidate as much as possible into the Community Care Network, pulling in a lot of services that were not previously covered, but it’s still not covering 100% of all services that veterans need outside VA medical centers,” said Brill.

Although the VA continues to rely on Veterans Care Agreements, in which health care providers contract directly with the VA, “the main focus of community care is the Community Care Network.” Said Brill. In a pair of regions—encompassing the Midwest, Northeast, and a few other states—90% of private health services are now provided through the network, she said.

One benefit of the new system is a better experience for the health care providers who work with Optum and TriWest. These administrators are responsible for finding providers and providing them with credentials based on appropriate criteria, Brill said. “In prior days, VA paid community providers directly, and some of you may be familiar with the delays that occurred in the system,” she said. “In the new system, we have third-party administrators who pay the providers quickly, and then VA pays them.”

Urgent care services are now available through CCN in most of the continental US and will be expanded to Texas, the Mountain region and the West by the end of September, she said. “We’ve been very pleased to see the response.” Meanwhile, flu shots for enrolled veterans are now available through the system via 60,000 locations.

There are requirements for private health care providers: They must meet new training requirements and submit claims within 180 days. Patients also must meet standards to get community care. For example, patients are eligible for access if the VA can’t serve them within a 30-minute drive time for primary care and mental health care and a 60-minute drive time for specialty care. Similarly, veterans are eligible if they cannot get an appointment within 20 days for primary and mental health care and 28 days for specialty care.

However, Brill insisted, the Mission Act is “not a move toward privatization. Internal VA care is just as important as external VA care,” she said. “This just gives them more choice.”

Brill also noted that there’s more to the Mission Act than expanded access. For example, an expansion of the Program of Comprehensive Assistance for Family Caregivers Program “will start kicking in this fall and the winter,” she said. It will include families of veterans from all eras of service.

The act also is designed to improve infrastructure, although the coronavirus pandemic may disrupt timing, she said. And, she added, it will strengthen the VA’s ability to recruit and keep health care providers through projects like a new scholarship program and more access to medical education debt reduction.

Human papilloma virus (HPV)-mediated squamous cell carcinoma of the head and neck is on the rise, and the lack of herd immunity in young people will ensure growth for many years to come. “We’re really looking at another 30 to 40 years of HPV and oropharynx cancer growth,” said head and neck cancer surgeon Joseph Califano, MD, deputy director of the Moores Cancer Center at the University of California at San Diego, at the virtual 2020 annual meeting of the Association of VA Hematology/Oncology (AVAHO).

            Califano highlighted a 2019 study that estimated the number of diagnoses of oropharynx cancer cases in the US will grow by half to 30,000 by 2030, with the wide majority (about 25,000) in men. In 2016, the annual number of oropharynx cancer cases was 20,124. “The exponential increase in oropharynx cancer incidence in young white US men has ebbed, and modest increases are occurring/anticipated in cohorts born after 1955,” the study authors wrote.

            “Currently in the United States, we don't have adequate vaccine efficiency to provide herd immunity, particularly for young boys,” said Califano. He added that although HPV vaccinations may create herd immunity in 5 to 10 years, the cancers associated with HPV can take decades to develop so a dip in rates won’t come for many years.

            HPV-associated head and neck squamous cell cancer (HNSCC) affects people at a younger age when compared with other head and neck cancers—a decade or 2 earlier, according to Califano. Many patients are nonsmokers and nondrinkers, he said, and tumors may be painless and asymptomatic.

            It’s also becoming clear that the HPV-associated HNSCC can strike across a widespread area of the oropharynx, including the palatine and lingual tonsils, the nasal cavity, nasopharynx, and hypopharynx (the lower part of the voice box), he said. “It has an even larger footprint than we originally supposed when we realized HPV was a dominant mechanism for development of oropharyngeal cancer,” said Califano.

            Describing the extent of these cancers as an “epidemic,” Califono said a turning point in the understanding of HPV’s role in oropharynx cancers came in a “definitive” 2001 study that reported that HPV-positive patients were much more likely to develop oropharynx cancer (adjusted odds ratio, 14.4). Later research found that HPV-associated oropharynx cancers were more common than HPV-associated cervical cancer. Higher lifetime numbers of vaginal sex and oral sex partners are linked to higher risk of HPV-mediated HNSCC, he said, as is prolonged daily marijuana use.

            Califano emphasized the importance of counseling patients about sexual behaviors linked to the cancers, although it’s also important to consider that “the majority of patients don’t have these risk factors.”

            “The diagnosis is not an indication of infidelity or promiscuity,” he added, recalling that he saw at least one marriage dissolve because of “misunderstandings” regarding how the cancer is caused.  

            There are multiple treatment options. Early-stage oropharynx cancers can be treated with primary excision and staging neck dissection or radiotherapy. Multimodality therapy is appropriate for late-stage cancer and can include concurrent chemotherapy and radiation, primary excision, and treatment with concurrent cisplatinum, depending on the case. Also, “patients do really benefit if they’re enrolled in clinical trials.”

The good news is that HPV-positivity is associated with improved survival in oropharynx cancer, he said. He highlighted a 2019 study that said radiotherapy and cisplatin improve survival in HPV-positive oropharynx cancer patients. “This has become the de-facto standard of care for locally advanced, low-risk HPV-positive oropharynx cancer,” he said.

Califano reported no relevant disclosures.

Proton pump inhibitors may short-circuit the benefits of atezolizumab (Tecentriq) in patients with advanced/metastatic urothelial cancer, according to a post hoc analysis of 1,360 subjects from two atezolizumab trials.

Proton pump inhibitor (PPI) use was associated with worse overall and progression-free survival among patients on atezolizumab, but there was no such association in a matched cohort receiving chemotherapy alone. In short, concomitant “PPI users had no atezolizumab benefit,” wrote the investigators led by Ashley Hopkins, PhD, a research fellow at Flinders University in Adelaide, Australia.

This is the first time that PPI use has been shown to be an independent prognostic factor for worse survival in this setting with atezolizumab use – but not with chemotherapy, wrote the authors of the study, published online in Clinical Cancer Research.

“PPIs are overused, or inappropriately used, in patients with cancer by up to 50%, seemingly from a perspective that they will cause no harm. The findings from this study suggest that noncritical PPI use needs to be approached very cautiously, particularly when an immune checkpoint inhibitor is being used to treat urothelial cancer,” Hopkins said in a press release.

Although about one third of cancer patients use PPIs, there has been growing evidence that the changes they induce in the gut microbiome impact immune checkpoint inhibitor (ICI) effectiveness. A similar study of pooled trial data recently found that PPIs, as well as antibiotics, were associated with worse survival in advanced non–small cell lung cancer treated with atezolizumab, while no such tie was found with chemotherapy (Ann Oncol. 2020;31:525-31. doi: 10.1016/j.annonc.2020.01.006).

The mechanism is uncertain. PPIs have been associated with T-cell tolerance, pharmacokinetic changes, and decreased gut microbiota diversity. High diversity, the investigators noted, has been associated with stronger ICI responses in melanoma. Antibiotics have been associated with similar gut dysbiosis.

“It is increasingly evident that altered gut microbiota impacts homeostasis, immune response, cancer prognosis, and ICI efficacy. The hypothetical basis of [our] research is that PPIs are associated with marked changes to the gut microbiota, driven by both altered stomach acidity and direct compound effects, and these changes may impact immunotherapy,” Hopkins said in an email to Medscape.

The associations with urothelial cancer hadn’t been investigated before, so Hopkins and his team pooled patient-level data from the single-arm IMvigor210 trial of atezolizumab for urothelial cancer and the randomized IMvigor211 trial, which pitted atezolizumab against chemotherapy for the indication.

The investigators compared the outcomes of the 471 subjects who were on a PPI from 30 days before to 30 days after starting atezolizumab with the outcomes of 889 subjects who were not on a PPI. Findings were adjusted for tumor histology and the number of prior treatments and metastases sites, as well as age, body mass index, performance status, and other potential confounders.

PPI use was associated with markedly worse overall survival (hazard ratio, 1.52; 95% confidence interval, 1.27-1.83; P < .001) and progression-free survival (HR, 1.38; 95% CI, 1.18-1.62; P < .001) in patients on atezolizumab but not chemotherapy. PPI use was also associated with worse objective response to the ICI (HR, 0.51; 95% CI, 0.32-0.82; P = .006).

In the randomized trial, atezolizumab seemed to offer no overall survival benefit versus chemotherapy when PPIs were onboard (HR, 1.04; 95% CI, 0.81-1.34), but atezolizumab offered a substantial benefit when PPIs were not in use (HR, 0.69; 95% CI, 0.56-0.84). Findings were consistent when limited to the PD-L1 IC2/3 population.

It seems that PPIs negate “the magnitude of atezolizumab efficacy,” the investigators wrote.

Concomitant antibiotics made the effect of PPIs on overall survival with atezolizumab even worse (antibiotics plus PPI: HR 2.51; 95% CI, 1.12-5.59; versus no antibiotics with PPI: HR, 1.44; 95% CI, 1.19-1.74).

The investigators cautioned that, although “the conducted analyses have been adjusted, there is the potential that PPI use constitutes a surrogate marker for an unfit or immunodeficient patient.” They called for further investigation with other ICIs, cancer types, and chemotherapy regimens.

The dose and compliance with PPI therapy were unknown, but the team noted that over 90% of the PPI subjects were on PPIs for long-term reasons, most commonly gastric protection and gastroesophageal reflux disease (GERD). Omeprazole, pantoprazole, and esomeprazole were the most frequently used. 

There were no significant associations between PPI use and the first occurrence of atezolizumab-induced adverse events.

The study was funded by the National Breast Cancer Foundation (Australia) and the Cancer Council South Australia. Hopkins has disclosed no relevant financial relationships. Multiple study authors have financial ties to industry, including makers of ICIs. The full list can be found with the original article.
