LAS VEGAS – Is the relationship between major depressive disorder and the development of cancer, cardiovascular disease, and other medical conditions a coincidence, or is there more at play?

According to Charles B. Nemeroff, MD, PhD, a host of circumstances potentially underlies this association, including treatment of the medical disorder itself.

“The best example of that is probably the use of interferon-alpha for the treatment of malignant melanoma,” Dr. Nemeroff, professor and chair of the department of psychiatry and behavioral sciences at the University of Texas at Austin, said during an annual psychopharmacology update held by the Nevada Psychiatric Association. “Many patients treated with interferon-alpha ended up with very severe depression, including several documented suicides. Another possibility of the relationship between depression and medical disorders is that treating a patient for depression could result in a medical disorder. The best example of this is the use of 20 mg of olanzapine to augment the effects of an antidepressant, resulting in a 50-pound weight gain and the development of type 2 diabetes and metabolic syndrome. Both of those scenarios are well understood.”

Then there’s the behavioral aspects of the relationship, he continued, in which patients adopt the mindset that “I’m depressed. I don’t want to exercise. I’m a couch potato. I have been gaining a lot of weight. It’s bad for my heart.”

Converging biology is another possibility. “Is it possible that the biology of depression is linked to the biology of other disorders?” asked Dr. Nemeroff, who directs the university’s Institute for Early Life Adversity Research. “We can talk about this in relation to thyroid disease, a well known cause of depression, but we can also talk about the relationship to other disorders. There’s amazing epidemiologic evidence that patients with PTSD are much more likely to develop Alzheimer’s disease than patients without PTSD.”

Psychosocial issues also play a role. He recalled seeing patient in a clinic for the underserved who had underlying severe ulcerative colitis and anemia and couldn’t afford medical treatment. “The patient had a low hemoglobin, so it was impossible to distinguish between that and whether they had a primary depressive disorder or not,” he said.

In a study that explored the relationship between major depression and cancer, Dr. Nemeroff and colleagues found that the prevalence was highest in those with pancreatic cancer (50%), followed by oropharyngeal (40%), colon (13-25%), breast (18-25%), and gynecologic (23%), and Hodgkin’s lymphoma (17%) (Arch Gen Psychiatry 1995;52[2]:89-99). “Not all cancers have the same rate of depression,” he said. “One of the central questions is, not so much is the cancer patient depressed, but is depression a risk factor for developing cancer? The answer is a resounding yes. But what we don’t know is if you treat the depression aggressively, can you reduce that risk of either developing cancer or the progression of cancer?”

Dr. Nemeroff spotlighted several studies largely from the oncology literature, including a prospective survival analysis of 578 women with early-stage breast cancer (Lancet 1999;354:1331-6). After 5 years, 395 were alive and without relapse, 50 were alive with relapse, and 133 had died. The researchers found a significantly increased risk of death from all causes by 5 years in women with a high depression score (HR 3.59). There was a significantly increased risk of relapse or death at 5 years in women with high scores on helplessness and hopelessness measures.

In an analysis of the association between breast cancer and traumatic events, women who had severe stress or a traumatic event had lower rates of disease-free intervals (J Psychosomatic Res 2007;63:233-9). Another study by the same investigators found that a decrease in depression symptoms is associated with longer survival in patients with metastatic breast cancer (J Clin Oncol 2010;29:413-20). The median survival was 53.6 months for women with decreasing depression scores over 1 year and 25.1 months for women with increasing depression scores.

A more recent study of cervical cancer patients found that those exposed to psychological stress had an increased risk of cancer-specific mortality (HR 1.33) (Cancer Res 2019;79:3965-72). The association was mainly driven by distress experienced within 1 year before or after diagnosis (HR 1.30) but not afterward (HR 1.12). In addition, data from the large longitudinal Nurses’ Health Study II found that women with high PTSD symptoms had a twofold greater risk of ovarian cancer compared with women who had no trauma exposure (Cancer Res 2019;79:5113-20).

Authors of a separate study analyzed data from the Women’s Health Initiative to examine if depression precedes the development of a cancer diagnosis. They found that depression 3 years before a diagnosis of breast cancer was associated with all-cause mortality (HR 1.35) (Cancer 2017;123[16]:3107-15). Meanwhile, among women with late-stage breast cancer, newly developed depression at year 3 was significantly associated with all-cause mortality (HR 2.0) and breast cancer-specific mortality (HR 2.42). “That’s a pretty amazing finding,” Dr. Nemeroff said. “We have to think about depression as a systemic illness. What is depression doing that’s creating a fertile environment for cancer or worsening of cancer?”

He then discussed the risk of suicide in patients who are newly diagnosed with cancer. “No one ever talks about this, and I can’t get anybody to support research in this area,” he said. In one of the first studies on the topic, researchers conducted a case-control study of Medicare patients and determined risk of suicide among those with cancer was 2.3-fold higher compared with controls, even after adjustment for psychiatric illness and the risk of dying within a year (J Clin Oncol 2008;26[29]:4720-4). More recently, authors of a large population-based study in England found that the overall standardized mortality ratio for suicide was 1.20 (JAMA Psychiatry 2019;76[1]51-60). The risk was highest among patients with mesothelioma, with a 4.51-fold risk, followed by pancreatic (3.89-fold), esophageal (2.65-fold), lung (2.57-fold), and stomach cancer (2.20-fold). “They reported that the first 6 months after the diagnosis is associated with an increased risk of suicide – unrelated to prognosis,” Dr. Nemeroff said.

A separate analysis of SEER data from 1973-2014 and comprising more than 8.6 million cancer patients found that newly diagnosed cancer patients are 4.4 times more likely to die from suicide than patients in the same age group without cancer (Nat Commun 2019;10[1]:207). The highest risk was in lung cancer, followed by head and neck, testes, bladder, and Hodgkin’s lymphoma.

According to Dr. Nemeroff, the association between depression and the risk of certain forms of cancer or with a poor cancer prognosis “may have to do with immune function. Depression is associated with a change in inflammatory markers that very likely control the microenvironment of the tumor.” For example, he said, if the depressed environment is associated with a marked increase in tumor necrosis factor, interleukin 6, and other inflammatory markers, “that probably contributes to the body’s ability to fight disease. Ironically, depression is associated with an increase in inflammation but a decreased in T cell function. Remember, there are two fundamental types of immunity: the antibody response and the cellular response. What’s odd about depression is that there’s an increase in inflammatory markers but a decrease in the ability of T cells to function in terms of cellular immunity.”

Dr. Nemeroff disclosed that he has served as a consultant and/or scientific adviser for numerous pharmaceutical companies. He has received research and grant support from the National Institutes of Health.

A new meta-analysis provides more evidence that taller people may be more likely than their shorter peers to develop colorectal cancer (CRC) or colon polyps.

“There are well-known modifiable dietary associations for colorectal cancer, such as processed red meats and smoking, but guidelines currently are fixated on family history, and height is clinically neglected when it comes to risk screening,” study investigator Gerard Mullin, MD, with Johns Hopkins University, Baltimore, said in a news release. This large study “builds on evidence that taller height is an overlooked risk factor and should be considered when evaluating and recommending patients for colorectal cancer screenings.”

The study was published online March 1 in Cancer Epidemiology, Biomarkers & Prevention.
 

The evidence: Height and cancer risk

Height has been actively studied as a potential nonmodifiable risk factor for a range of cancers, including CRC.

In one large prospective study of postmenopausal women, researchers found a modest but statistically significant positive association between height and risk for any cancer and for melanoma, multiple myeloma, and cancers of the thyroid, ovary, colorectum, and endometrium. 

A separate study found that tall men, especially those who are long-legged, may be at increased risk for prostate cancer, including high-grade tumors, relative to men of more modest stature.

However, the study authors point out, past studies have also produced mixed results, used inconsistent measures of height, and failed to include the risk of adenomas.  

In the current meta-analysis, the investigators included 47 international, observational studies involving 280,644 adults with CRC and 14,139 cases of colorectal adenoma.

Because the definition of tallness differs around the world, the researchers compared the highest versus the lowest height percentile of various study groups. The findings were adjusted for demographic, socioeconomic, behavioral, and other known risk factors for CRC.

Overall, the investigators found that the tallest individuals within the highest percentile of height had a 24% higher risk of developing CRC compared to the shortest individuals within the lowest percentile (hazard ratio [HR], 1.24; P < .001).

In addition, they found that every 10-cm increase (about 4 inches) in height was associated with a 14% increased risk of developing CRC (HR, 1.14; P < .001) and a 6% increased likelihood of adenomas (odds ratio [OR], 1.06; P = .03).

In the United States, the average height for men is 5 feet, 9 inches, and for women it is 5 feet, 4 inches, which means men who are 6 feet, 1 inch and women who are 5 feet, 8 inches or taller have a 14% increased risk of CRC and a 6% increased risk of adenomas, the researchers explained.

According to co–first author Elinor Zhou, MD, also with Johns Hopkins University, a potential explanation for this link “is that adult height correlates with body organ size. More active proliferation in organs of taller people could increase the possibility of mutations leading to malignant transformation.”

The study authors said more research is needed to identify particular subgroups of tall people at risk for CRC.

“For instance, tall athletes and individuals with inherited tallness, such as those with Marfan syndrome, could be screened earlier and the impact of height further explored,” Dr. Zhou said.

Plus, Dr. Zhou added, more studies are needed to “definitively say at what height you would need earlier colorectal cancer screening.”

The current study was supported by grants from Bloomberg Philanthropies, intramural funds, and the Johns Hopkins Cancer Center Support Grant. The authors declared no conflicts of interest.

All 15 members of Wake Forest Baptist Comprehensive Cancer Center’s external advisory board (EAB) resigned on February 18 and withdrew their endorsement for renewal of the center’s National Cancer Institute comprehensive cancer center support grant.

The move was prompted by the abrupt firing of center director Boris Pasche, MD, PhD, on February 10, one day after NCI renewed a multimillion dollar grant.

The Cancer Letter broke the story and published the resignation letter from the EAB. It was signed by board chair Gerold Bepler, MD, PhD, CEO and director of the Karmanos Cancer Institute, Detroit, on behalf of the board.

The mass resignation of an EAB, a panel of outside experts that help shepherd cancer centers through the NCI grant process, is “highly unusual,” according to The Cancer Letter. It also raises concerns about the “immediate future” of Wake Forest’s cancer center, the publication added.

Numerous people involved with the situation did not respond or declined to comment when this news organization requested additional information and updates, including questions about the reason for Dr. Pasche’s termination; whether or not withdrawal of the endorsement puts Wake’s NCI designation in jeopardy; and if the EAB is being reconstituted.

A written statement from Wake Forest simply said that “the situation involving Dr. Pasche is an administrative decision. Various administrative changes occur regularly in organizations across the country. Dr. Pasche remains employed by Atrium Health Wake Forest Baptist. We are very grateful to Dr. Pasche for his years of service and many contributions to the mission and vision of our NCI-designated Comprehensive Cancer Center in Winston-Salem.”

Wake’s cancer center is in the process of combining with the Atrium Health Levine Cancer Center, which is not NCI-designated, following Atrium Health system’s recent acquisition of the Wake Forest Baptist Medical Center.

The NCI renewal notice, dated February 9, states that Dr. Pasche “and his leadership team have built a robust, transdisciplinary center that includes 140 scientists.”

Dr. Pasche was fired a day later.

The EAB resignation letter states that during Wake Forest’s recent NCI review process, “leadership gave their glowing endorsement of Dr. Pasche...This endorsement included unequivocal statements of support for Dr. Pasche’s oversight of the combined Atrium-Wake Forest cancer program.”

“What followed was his rapid dismissal after the...notice of award was issued, following a period during which the approach to integration was apparently being revisited,” Dr. Bepler said on behalf of the board.

“It is with sadness and dismay that we witnessed the change in approach by the institutional leadership towards” the merger, he wrote.

The Cancer Letter quotes an unnamed board member as saying, “EABs for cancer centers can only provide value to the center when there is openness and transparency in the process. In the absence of such, I believe the members felt that there was no further utility in providing guidance to the organization.”

The resignation letter was sent to the interim director of Wake’s cancer center, radiation oncologist William Blackstock, Jr, MD, and also copied to Atrium-Wake and NCI leadership.

The resignation letter endorsed Dr. Blackstock’s qualifications to run the center, and noted that as the board is reconstituted, “some of us would be honored to discuss participation...if there is unequivocal evidence from the health system’s senior management for support of a single, academically driven, comprehensive, and integrated cancer center.”

Among women with ATM, CHEK2, or PALB2 pathogenic variants, annual MRI screening beginning at age 30 or 35, followed by concomitant MRI and mammography at age 40, could significantly reduce breast cancer mortality, according to a new model.

Adjunct screening with MRI is already recommended among women with the BRCA1 or BRCA2 mutations. ATM, CHEK2, and PALB2 are the most common of a more recently discovered group of pathogenic variants that confer a moderate to high risk of breast cancer.

In a study published online Feb. 17, 2022, in JAMA Oncology, researchers used two simulation models and risk estimates from the Cancer Risk Estimates Related to Susceptibility Consortium to predict that MRI screening at age 35 would produce a 54.4%-57.6% reduction in breast cancer mortality, with an estimated 4,661-5,001 false positive screenings and 1,280-1,368 benign biopsies per 1,000 women. At age 30, the model predicted 55.4-59.5% reduction in risk, 5,075-5,415 false positives, and 1,439-1,528 benign biopsies. Annual mammography at age 40 alone could reduce risk by 36%-39%.

The false positives and benign biopsies represent cumulative lifetime results.

“We’ve known for a long time that mammography is less sensitive in younger women than in older women and, of course, when women have a genetic predisposition, we’re very concerned about early-onset cancer. We’ve also known that when you do MRI at the same time as mammography, you find a lot more cancers. [There are] more false positives, but there is clearly a greater yield of cancer in that setting, and the cancers are found earlier,” senior author Mark Robson, MD, said in an interview.

The model showed that mammography screening in women under 40 added no survival benefit, and led to additional false positives and benign biopsies.

“We know that MRI’s detection rate for cancers in a head-to-head comparison with mammography is extremely high, and so I’m not surprised that there was such a difference from a mammography strategy. What I was excited by is just how impactful the MRI screen was in terms of projected reduction in the risk of death. I thought that great,” said Dr. Robson, who is chief of the breast medicine service at Memorial Sloan Kettering Cancer Center, New York.

The balance of mortality reduction versus false positives and benign biopsies will need to be weighed by others. “We didn’t feel like we could make those judgments, but what we were presenting was for people who do make these kinds of policies. The reason that we said 30-35 years (for MRI initiation) is because at that point, the false positive versus life-years gained curve starts to plateau. For instance, when we look at strategies of starting MRI at 25, you we don’t get significantly more life years gained, but we do get more false positives,” Dr. Robson said.

The researchers did not conduct a former cost-benefit analysis for initiating MRI screening at age 30-35.

The study “reinforces the value of MRI for women with these variants that are really just entering the clinical consciousness, and affirms that we need to be doing that in young women to help prevent death from breast cancer. I also think that we need to look at really what mammogram is adding in young women and consider whether or not we really need it at the policy level,” he said.

The study was funded by the National Cancer Institute and the Breast Cancer Research Foundation. Dr. Robson has conducted clinical trials with AstraZeneca, Merck, and Pfizer.

A study of testicular cancer mortality finds worse outcomes among Hispanic men, but better outcomes among Black men.

The findings were reported at the American Society of Clinical Oncology Genitourinary Cancers Symposium.

Incidence rates for testicular cancer in the United States have increased slowly in recent decades, said Anushka Ghosh, a clinical research coordinatory with Massachusetts General Hospital, Boston. Her analysis found mortality increases from 1999 to 2019 to be significantly greater among Hispanic men. The increase was 0.0019 per 100,000, compared with a 0.0003 per 100,000 decrease among non-Hispanic men (comparison P = .010).

Among Black men, testicular cancer–specific mortality rates declined by 0.0007 per 100,000, compared with a marginally significant increase of 0.0006 per 100,000 among White men (P =.049).

“Given that testicular cancer generally has a favorable prognosis, it is concerning that the mortality rate for this disease is increasing,” said Sophia C. Kamran, MD, the study’s lead author and a radiation oncologist at Massachusetts General Hospital.

Dr. Kamran urged new efforts to understand these trends and to make testicular cancer care more accessible for all patients.

Ms. Ghosh said that other researchers have identified the same disparity among Hispanic men with prostate cancer. “Even though testicular cancer is a rare, our finding warrants further investigation to find the basis of these disparities to better serve the Hispanic community.”

Other studies have shown higher likelihood of later stage diagnosis and worse survival outcomes among Black patients.

No funding sources were reported for this study.

Unless air pollution and smoking patterns are reversed, lung cancer cases and deaths will grow unabated in some countries, according to estimates of lung cancer incident cases, deaths, and their age-standardized rates.

The findings, based on recently released data from GLOBOCAN 2020 projected to the year 2050, suggest that the lung cancer epidemic will continue to unfold, according to Rajesh Sharma, PhD, et al., in a study published in the International Journal of Clinical Oncology. GLOBOCAN 2020 is an online database produced by the International Agency for Research on Cancer. It provides global cancer statistics from 185 countries for 36 cancer types.

The increase in lung cancer, the leading cancer worldwide in terms of deaths, is generally attributed to increases in cigarette smoking, Sharma et al. wrote. They point out that, while cigarette smoking is expected to have peaked in industrialized countries in the latter half of the twentieth century, the tobacco smoking epidemic is unfolding in regions of Asia and Africa with concomitant increases in lung cancer burden in several countries. Smoking is the most significant lung cancer risk factor, followed by air pollution (especially particulate matter, passive smoking, and occupational exposure to radon and asbestos).

The authors investigated bivariate associations between smoking prevalence and age-standardized rates of lung cancer, and projected lung cancer incident cases and deaths to 2050. They also looked at mortality-to-incidence, considered to be a proxy indicator of 5-year survival, and at human development index, a measure including life expectancy at birth, years of schooling, and standard of living. The results, they state, are expected to aid in policy formulation to combat the lung cancer burden at global, regional, and national levels.

Tobacco smoking prevalence was 21.9% worldwide in 2016, with tobacco smoking prevalence exceeding 25% in 57/149 countries. It was high in European countries with 5 of the top-10 countries among the 149 countries within Europe. Prevalence was greater than 10% in all European countries. Notably, 11/33 countries in Africa had a smoking prevalence less than 10%.

Analysis showed 2.21 million new lung cancer cases and 1.8 million deaths attributed to lung cancer worldwide in 2020, with males accounting for about two-thirds of the burden. The analysis projection for 2050 was for 3.8 million incident cases of lung cancer and 3.2 million lung cancer deaths globally. In 2050, lung cancer cases and deaths are projected to be more than 100,000 in 10/21 regions, led by Eastern Asia, projected to record 1.7 million incident cases and 1.5 million deaths.

The burden of lung cancer in regions of Asia and Africa is expected to increase at least twofold from 2020 to 2050, surpassing European regions that are expected to have the smallest increases. Also, while incident cases will remain much higher in Northern America than in Southeastern Asia and South-Central Asia, the number of lives lost is projected to be similar. The age-specific incidence and death rates rose with age such that the oldest age groups had the highest age-specific rates. With the human development index, mortality-to-incidence showed a negative correlation.

The authors wrote that worsening smoking and pollution levels in developing countries may push the future lung cancer burden much higher than these projections. Unless reversed, cases and death will grow unabated.

“Countering the burden of lung cancer also requires curtailment of other risk factors such as air pollution and exposure to carcinogens,” the authors wrote.

This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors. The authors stated that they have no conflicts of interest.

In 2050, lung cancer cases and deaths are projected to be more than 100,000 in 10/21 regions, led by Eastern Asia, projected to record 1.7 million incident cases and 1.5 million deaths.

The burden of lung cancer in regions of Asia and Africa is expected to increase at least twofold from 2020 to 2050, surpassing European regions that are expected to have the smallest increases. Also, while incident cases will remain much higher in Northern America than in Southeastern Asia and South-Central Asia, the number of lives lost is projected to be similar. The age-specific incidence and death rates rose with age such that the oldest age groups had the highest age-specific rates. With the human development index, mortality-to-incidence showed a negative correlation.

The authors wrote that worsening smoking and pollution levels in developing countries may push the future lung cancer burden much higher than these projections. Unless reversed, cases and death will grow unabated.

“Countering the burden of lung cancer also requires curtailment of other risk factors such as air pollution and exposure to carcinogens,” the authors wrote.

This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors. The authors stated that they have no conflicts of interest.

The rate of recurrence of the rare but aggressive skin cancer Merkel cell carcinoma (MCC) is markedly higher than that for invasive melanoma, squamous cell carcinoma, or basal cell carcinoma, and more than half of all patients with stage IV disease will have a recurrence within 1 year of definitive therapy, results of a new study show.

A study of 618 patients with MCC who were enrolled in a Seattle-based data repository shows that among all patients the 5-year recurrence rate was 40%. The risk of recurrence within the first year was 11% for patients with pathologic stage I disease, 33% for those with stage IIA/IIB disease, 45% for those with stage IIIB disease, and 58% for patients with pathologic stage IV MCC.

Approximately 95% of all recurrences happened within 3 years of the initial diagnosis, report Aubriana McEvoy, MD, from the University of Washington in Seattle, and colleagues.

“This cohort study indicates that the highest yield (and likely most cost-effective) time period for detecting MCC recurrence is 1-3 years after diagnosis,” they write in a study published online in JAMA Dermatology.

The estimated annual incidence of MCC in the United States in 2018 was 2,000 according to the American Cancer Society. The annual incidence rate is rising rapidly, however, and is estimated to reach 3,284 by 2025, McEvoy and colleagues write.

Although MCC is known to have high recurrence rates and is associated with a higher mortality rate than malignant melanoma, recurrence rate data are not captured by either the Surveillance, Epidemiology, and End Results (SEER) database or by the National Cancer Database. As a result, estimates of recurrence rates with MCC have been all over the map, ranging from 27% to 77%, depending on the population studied.

But as senior author Paul Nghiem, MD, PhD, professor and chair of dermatology at the University of Washington, Seattle, told this news organization, recurrence rates over time in their study were remarkably consistent.

“The biggest surprise to me was that, when we broke our nearly 20-year cohort into three 5- or 6-year chunks, every one of the groups had a 40% recurrence rate, within 1%. So we feel really confident that’s the right number,” he said.

Dr. Nghiem and colleagues report that, in contrast to patients with MCC, approximately 19% of patients with melanoma will have a recurrence, as will an estimated 5%-9% of patients with squamous cell carcinoma and 1%-10% of patients with basal cell carcinoma.

The fact that recurrence rates of MCC have remained stable over time despite presumed improvements in definitive therapy is disappointing, Dr. Nghiem acknowledged. He noted that it’s still unclear whether immunotherapy will have the same dramatic effect on survival rates for patients with MCC as it has for patients with malignant melanoma.

The high recurrence rates following definitive therapy for patients with early-stage disease was a novel finding, commented Shawn Demehri, MD, PhD, director of the high-risk skin cancer clinic at Massachusetts General Hospital in Boston.

“When you’re looking at patients with stage I or stage II, and they have definitive surgery but still have recurrences at a higher rate than melanoma, it brings home the point that these are among the most aggressive tumors of the skin,” he said in an interview.

The high recurrence rates seen with MCC are attributable to a variety of factors.

“This is a rare cancer of mostly older individuals with a lot of comorbidities, and also a cancer that, even though it is a primary cancer, might be detected a little later than even a melanoma primary tumor, just because of the nature of the neuroendocrine tumor cells,” he said.

Dr. Demehri was not involved in the study.
 

Prospective cohort

The study cohort consisted of 618 patients with MCC. The median age of the patients was 69, and 227 (37%) were women. The patients were enrolled within 6 months of their diagnosis in the prospective data repository from 2003 through 2019. Of this group, 223 had a recurrence of MCC.

As noted, there was a high risk of recurrence within 1 year, ranging from 11% for patients with pathologic stage I tumors to 58% for those with stage IV disease, and 95% of all recurrences occurred within 3 years of definitive therapy.

To get a better picture of the natural history of MCC recurrence, the investigators studied a cohort of patients with pathologically confirmed MCC who were prospectively enrolled from January 2003 through April 2019 in a data repository maintained at the University of Washington.

In addition to disease stage, factors associated with increased recurrence risk in univariable analyses include immunosuppression (hazard ratio, 2.4; P < .001), male sex (HR, 1.9; P < .001), known primary lesion among patients with clinically detectable nodal disease (HR, 2.3; P = .001), and older age (HR, 1.1, P = .06 for each 10-year increase).

Of the 187 patients in the cohort who died during the study, 121 died from MCC. At 4 years after diagnosis, MCC-specific survival rates were 95% for patients with pathologic stage I, 84% with stage IIA/IIB, 80% with stage IIIA, 58% with stage IIIB, and 41% with stage IV.

Evidence supports close monitoring within the first 3 years for patients with stage I-II MCC. Local recurrence within or adjacent to the primary tumor scar was associated with a 5-year MCC-specific survival rate of 85%, compared with 88% of patients with stage I or II disease who did not have recurrences.

“Because more than 90% of MCC recurrences arise within 3 years, it is appropriate to adjust surveillance intensity accordingly. Stage- and time-specific recurrence data can assist in appropriately focusing surveillance resources on patients and time intervals in which recurrence risk is highest,” the authors wrote.

“If you’re a patient who has not had your cancer come back for 3, 4, or 5 years, you can really cut down on the intensity of your follow-up and scans,” Dr. Nghiem said.

“We do now have two excellent blood tests that are working very well, and we have really good ways to detect the cancer coming back early, and that’s important, because we have potentially curative therapies that tend to work better if you catch the cancer early,” he said.

The study was supported by the National Institutes of Health. Dr. Nghiem reported personal fees and institutional support outside the study from several companies and patents for Merkel cell therapies with the University of Washington and University of Denmark. Dr. Demehri has disclosed no relevant financial relationships.

PHOENIX – A liquid biopsy test may accurately predict recurrence of human papillomavirus (HPV)–driven oropharyngeal squamous cell carcinoma (OPSCC) earlier than standard clinical and imaging assessments, a new analysis indicates.

Of 80 patients who tested positive for circulating tumor tissue–modified viral (TTMV)-HPV DNA during surveillance, 74% (n = 59) had no other evidence of disease or had indeterminate disease status.

And of those patients, 93% (n = 55) “later had proven recurrent, metastatic disease on imaging and/or biopsy,” according to Glenn Hanna, MD, from the Dana-Farber Cancer Institute, Boston, who presented the results Feb. 24 at the 2022 Multidisciplinary Head and Neck Cancers Symposium.

“This is the first study to demonstrate broad clinical utility and validity of the biomarker in HPV-driven oropharyngeal cancer,” Dr. Hanna said in a press release.

Although patients with HPV-driven OPSCC generally have favorable outcomes, up to 25% will experience recurrence after treatment.

Post-treatment surveillance currently relies on physical examinations and imaging, but Dr. Hanna and colleagues wanted to determine whether a routine circulating cell-free TTMV-HPV DNA test could detect occult recurrence sooner.

Dr. Hanna and colleagues analyzed the records of 1,076 patients with HPV-driven OPSCC at 118 sites in the U.S. who had completed therapy more than 3 months previously and undergone an TTMV-HPV DNA test (NavDx, Naveris) between June 2020 and November 2021.

The results of the test, which used ultrasensitive digital droplet PCR to identify HPV subtypes 16, 18, 31, 33, and 35, were compared with subsequent clinical evidence of OPSCC via nasopharyngolaryngoscopy, radiologic evaluations, or tissue biopsy.

Approximately 7% of the patients tested positive (n = 80) for circulating TTMV-HPV DNA. Of those, 26.2% (n = 21) had known clinical recurrence, while 73.8% (n = 59) had no other evidence of disease or an intermediate disease status.

Among those with no clinical evidence of recurrence, 93.2% (n = 55) had their recurrence subsequently confirmed using imaging or biopsy. Of the 4 remaining patients, 2 had clinically suspicious lesions, and 2 had no other evidence of disease.

Overall, the data indicate that the biomarker test demonstrated a 95% positive predictive value (76 of 80 patients) for recurrence or persistence of HPV-driven OPSCC.

According to Dr. Hanna, a positive TTMV-HPV DNA test was the first indicator of recurrence for 72% of patients, and almost half of recurrences were detected more than 12 months after completing therapy.

“Incorporating a test for TTMV-HPV DNA into routine post-treatment follow-up can enable physicians to detect recurrent cancers earlier and allow us to start recommended interventions more quickly to improve outcomes,” Dr. Hanna said in the release.

The study was supported by Naveris, which developed the TTMV-HPV DNA test studied. Dr. Hanna declares relationships with Actuate Therapeutics, Altor BioScience, Bicara, BMS, GSK, Merck, Regeneron, Sanofi/Genzyme, and others.

Incidence rates for testicular cancer have been rising in the United States, as have related mortality rates, but there are wide variations by race/ethnicity and geographic location, a new analysis shows.

Testicular cancer is the most common type of malignancy in young men between the ages of 20 and 34 years, although overall, it is relatively uncommon and represents only 0.5% of all new cancer cases in the U.S.

The new analysis shows that age-adjusted testicular cancer–specific mortality rates in the United States increased from 1999-2019, particularly among Hispanic men. During the same period, mortality rates declined somewhat among Black men as compared to White men.

“Given that testicular cancer generally has a favorable prognosis, it is concerning that mortality rates for this disease are increasing,” said lead author Anushka Ghosh, BS, a clinical research coordinator at Massachusetts General Hospital, Boston. “It is crucial to understand these trends and make targeted efforts to address any geographic, racial, and ethnic gaps in testicular cancer care.”

She presented the findings at the Genitourinary Cancers Symposium (GUCS) 2022.

“Testicular cancer is a rare but very curable disease,” said Daniel Geynisman, MD, associate professor in the Department of Hematology/Oncology at Fox Chase Cancer Center, Philadelphia, who was approached for comment. “The increase in testicular cancer deaths for Hispanic men is concerning.”

“Whether this change relates to suboptimal access to appropriate care or change in biology as a result of socioeconomic or geographic changes in Hispanic men over the recent years is unknown but needs to be urgently explored and addressed,” he added.
 

Details of the new findings

For their analysis, Ms. Ghosh and colleagues assessed recent changes in testicular cancer mortality rates over time in the United States with respect to race, ethnicity, and geography. They used the Centers for Disease Control’s Wide-Ranging Online Data for Epidemiologic Research database to obtain the number of age-adjusted death rates for individuals across all U.S. counties over a 21-year period (1999-2019).

During this period, overall age-adjusted testicular cancer mortality rates rose slowly but not significantly, with an overall increase of 0.0002 per 100,000 population per year. This increase was significantly worse among Hispanic men, among whom the increase was 0.0019 per 100,000, compared with a 0.0003 per 100,000 decrease among non-Hispanic men (comparison P = .010).

But when stratified by race (Black vs. White), the authors saw that Black men had somewhat improved rates. Among Black men, the rate decreased by 0.0007 per 100,000, compared with an increase of 0.0006 per 100,000 among White men, a difference that reached statistical significance (P = .049).

“We also observed significant geographical differences in mortality rates,” said Ms. Ghosh.

They divided the U.S. into four regions: the Northeast, the Midwest, the South, and the West. There were no differences in the South and the Midwest, but mortality rates decreased in the Northeast by 0.00092 per 100,000 and rose in the West by 0.00086 per 100,000 (P for difference between slopes = .032).

The authors also looked at differences in urbanization categories or population density and found that large central metro regions (central counties in metro areas with population greater than 1 million) and small metro regions (counties with population 50,000-249,999) were significantly different. While testicular cancer mortality rates decreased slightly in large central metropolitan regions by 0.0004, rates increased slightly in small metropolitan regions (0.0022; P for difference = .048). No other significant differences based on urbanization were noted.

Also approached for comment, Matt D. Galsky, MD, director of genitourinary medical oncology at the Tisch Cancer Institute at Mount Sinai, noted that the finding that testicular cancer mortality rates increased from 1999-2019 was not statistically significant.

However, there were significant trends among subgroups. Testicular cancer mortality increased during this period among Hispanic men, he pointed out. “Importantly, while statistically significant, the differences are numerically small. That said, testicular cancer is a generally a highly curable malignancy, so any disparities related to mortality may be notable and worth further investigation.

“There are several potential underlying causes of such disparities, some of which could be probed with additional clinical details, and some of which might involve a more complex interplay of access and tumor biology,” he continued. “For example, testicular cancers are broadly separated into two subtypes: seminoma and nonseminoma. Whether the trends in these two subtypes in Hispanic men are different compared to non-Hispanic men could be one clue into the observed disparities.”

Ms. Ghosh, Dr. Geynisman, and Dr. Galsky have disclosed no relevant financial relationships.

Incidence rates for testicular cancer have been rising in the United States, as have related mortality rates, but there are wide variations by race/ethnicity and geographic location, a new analysis shows.

Testicular cancer is the most common type of malignancy in young men between the ages of 20 and 34 years, although overall, it is relatively uncommon and represents only 0.5% of all new cancer cases in the U.S.

The new analysis shows that age-adjusted testicular cancer–specific mortality rates in the United States increased from 1999-2019, particularly among Hispanic men. During the same period, mortality rates declined somewhat among Black men as compared to White men.

“Given that testicular cancer generally has a favorable prognosis, it is concerning that mortality rates for this disease are increasing,” said lead author Anushka Ghosh, BS, a clinical research coordinator at Massachusetts General Hospital, Boston. “It is crucial to understand these trends and make targeted efforts to address any geographic, racial, and ethnic gaps in testicular cancer care.”

She presented the findings at the Genitourinary Cancers Symposium (GUCS) 2022.

“Testicular cancer is a rare but very curable disease,” said Daniel Geynisman, MD, associate professor in the Department of Hematology/Oncology at Fox Chase Cancer Center, Philadelphia, who was approached for comment. “The increase in testicular cancer deaths for Hispanic men is concerning.”

“Whether this change relates to suboptimal access to appropriate care or change in biology as a result of socioeconomic or geographic changes in Hispanic men over the recent years is unknown but needs to be urgently explored and addressed,” he added.
 

Details of the new findings

For their analysis, Ms. Ghosh and colleagues assessed recent changes in testicular cancer mortality rates over time in the United States with respect to race, ethnicity, and geography. They used the Centers for Disease Control’s Wide-Ranging Online Data for Epidemiologic Research database to obtain the number of age-adjusted death rates for individuals across all U.S. counties over a 21-year period (1999-2019).

During this period, overall age-adjusted testicular cancer mortality rates rose slowly but not significantly, with an overall increase of 0.0002 per 100,000 population per year. This increase was significantly worse among Hispanic men, among whom the increase was 0.0019 per 100,000, compared with a 0.0003 per 100,000 decrease among non-Hispanic men (comparison P = .010).

But when stratified by race (Black vs. White), the authors saw that Black men had somewhat improved rates. Among Black men, the rate decreased by 0.0007 per 100,000, compared with an increase of 0.0006 per 100,000 among White men, a difference that reached statistical significance (P = .049).

“We also observed significant geographical differences in mortality rates,” said Ms. Ghosh.

There were no differences in the South and the Midwest, but mortality rates decreased in the Northeast by 0.00092 per 100,000 and rose in the West by 0.00086 per 100,000 (P for difference between slopes = .032).

The U.S. Preventive Services Task Force (USPSTF) criteria for lung cancer screening should be expanded to include more women, especially those with a history of breast cancer, according to a new study published in BJS Open.

The 2021 screening guidelines include adults aged between 50 and 80 years who have a 20–pack-year smoking history and currently smoke or have quit within the past 15 years, but the guidelines do not include nonsmokers or patients with a history of previous malignancies, such as breast cancer.

Led by Daniela Molena, MD, a thoracic surgeon and director of esophageal surgery at Memorial Sloan Kettering Cancer Center, New York, researchers conducted an analysis of 2,192 women with first-time lung cancer who underwent lung resections at Memorial Sloan Kettering between January 2000 and December 2017. The study’s objective was to determine stage at diagnosis, survival, and eligibility for lung cancer screening among patients with lung cancer who had a previous breast cancer diagnosis and those who did not have a history of breast cancer.

Only 331 (15.1%) patients were previously diagnosed with breast cancer, which was not statistically significant. “Overall, there were no statistically significant differences in genomic or oncogenic pathway alterations between the two groups, which suggests that lung cancer in patients who previously had breast cancer may not be affected at the genomic level by the previous breast cancer,” the authors wrote.

However, at 58.4%, more than half of patients in the study (1,281 patients) were prior smokers and only 33.3% met the USPSTF criteria for lung cancer screening, which the authors said was concerning.

“The most important finding of the study was that a high percentage of women with lung cancer, regardless of breast cancer history, did not meet the current USPSTF criteria for lung cancer screening. This is very important given the observation that nearly half of the women included in the study did not have a history of smoking. As such, the role of imaging for other causes, such as cancer surveillance, becomes especially important for early cancer diagnosis,” Dr. Molena and colleagues wrote. “To reduce late-stage cancer diagnoses, further assessment of guidelines for lung cancer screening for all women may be needed.”

Instead, for almost half of women in the study group with a history of breast cancer, the lung cancer was detected on a routine follow-up imaging scan.

USPSTF guidelines for lung cancer screening do not include previous malignancy as a high-risk feature requiring evaluation, which may explain why so few women in this study were screened for lung cancer, even though lung cancer is more common in breast cancer survivors than the general population. Approximately 10% of women who have had breast cancer will develop a second malignancy within 10 years and in most cases, it will be lung cancer. Plus, according to the National Cancer Institute, breast, lung, and colorectal cancers are the three most common cancers in women and account for approximately 50% of all new cancer diagnoses in women in 2020.

A 2018 analysis published in Frontiers in Oncology found that, of more than 6,000 women with secondary primary lung cancer after having had breast cancer, 42% had distant-stage disease at the time of diagnosis which, Dr. Molena and colleagues said, suggests an ongoing need to update screening recommendations.

“Given that lung cancer has a 5-year overall survival rate of less than 20% (highlighting the benefits of early-stage diagnosis), a better understanding of lung cancer in women with a history of breast cancer could have important implications for screening and surveillance,” the authors wrote.

Estrogen is known to play a role in the development of lung cancer by activating the epidermal growth factor receptor (EGFR). Previous research has shown an increased risk of lung cancer in patients with estrogen receptor–negative, progesterone receptor–negative, HER2-negative, or triple-negative breast cancer.

“Antiestrogen treatment has been demonstrated to decrease the incidence of lung cancer and has been associated with improved long-term survival in patients with lung cancer after breast cancer. Future studies should seek to identify high-risk populations on the basis of hormone receptor status and antiestrogen therapy use,” the authors wrote.

The authors noted a number of limitations to the study, including the single hospital as the sole source of data, plus, the analysis did not account for the length of time since patients quit smoking and a lung cancer diagnosis. Nor did it consider other risk factors, such as radiation, chemotherapy, or antiestrogen therapies.

The authors did not disclose any study-related conflicts of interests.
