New research sheds light on how chronic heavy alcohol use may contribute to colorectal cancer (CRC) development and how quitting may lower the risk for precancerous colorectal adenomas.

In a large US cancer screening trial, current heavy drinkers — with an average lifetime alcohol intake of 14 or more drinks per week — had a 25% higher risk for CRC and an almost twofold higher risk for rectal cancer than light drinkers averaging less than one drink per week.

When the research team further considered drinking consistency, steady heavy drinking throughout adulthood was associated with a 91% higher risk for CRC than consistent light drinking. 

Additionally, no increased risk for CRC was found among former drinkers, and former drinkers were less likely than light drinkers to develop nonadvanced colorectal adenomas.

This analysis “adds to the growing amount of concerning literature showing that chronic heavy alcohol use can potentially contribute to colorectal cancer development,” Benjamin H. Levy III, MD, gastroenterologist and clinical associate of medicine at UChicago Medicine in Chicago, who wasn’t involved in the study, told Medscape Medical News.

The study’s co-senior author, Erikka Loftfield, PhD, MPH, also noted that the study “provides new evidence indicating that drinking cessation, compared to consistent light drinking, may lower adenoma risk.”

Current cancer prevention guidelines recommend limiting alcohol intake or ideally not drinking at all, and “our findings do not change this advice,” said Loftfield, with the National Cancer Institute (NCI) in Bethesda, Maryland. 

The study was published online on January 26 in the journal Cancer.

Addressing a Data Gap

Alcoholic beverages are classified as carcinogenic to humans and are causally associated with CRC, Loftfield told Medscape Medical News. However, much of the evidence for this comes from cohort studies that only measure recent drinking patterns, generally among older adults, at study baseline. Fewer studies have looked at how drinking over a person’s lifetime and alcohol consumption patterns relate to colorectal adenoma and CRC risk, she explained.

To address these gaps, Loftfield and colleagues leveraged data on alcohol intake gathered as part of the NCI’s Prostate, Long, Colorectal, and Ovarian Cancer Screening Trial.

Average lifetime alcohol intake was calculated as drinks per week from age 18 through study baseline, and drinking patterns were further classified based on consistency and intensity over time. 

During 20 years of follow-up, 1679 incident CRC cases occurred among 88,092 study participants. In multivariable-adjusted analyses, current heavy drinkers had a higher risk for CRC than those averaging less than one drink per week (hazard ratio [HR], 1.25), with the strongest association observed for rectal cancer (HR, 1.95).

“The increase in rectal cancer risk for heavy drinkers seen in this 20-year observational study was especially concerning,” Levy told Medscape Medical News.

What About Moderate Drinking?

Perhaps counterintuitively, moderate current drinkers (those consuming an average of 7 to less than 14 drinks per week) had a lower risk for CRC (HR, 0.79), especially distal colon cancer (HR, 0.64), than light drinkers.

Loftfield said that research in rodents suggests moderate alcohol intake may reduce inflammation and lower DNA damage, but it’s possible that the observed inverse association is due to residual confounding by unmeasured or poorly measured confounders, such as socioeconomic status.

She said it’s also important to note that the inverse association of moderate alcohol intake was strongest for distal colon cancer and in the screening arm of the trial. Those in the screening arm who screened positive with flexible sigmoidoscopy had polyps removed and were referred for colonoscopy during the trial period, making screening a potential intervention as well.

“Screening with flexible sigmoidoscopy has previously been found to decrease CRC incidence, specifically distal colon cancer, in this population. Thus, it is possible that better adherence to screening among moderate drinkers over the course of follow-up contributed to this finding,” Loftfield explained.

When looking at consistency of drinking, her team found that current drinkers who were consistent heavy drinkers throughout adulthood had a higher risk for CRC than consistent light drinkers (HR, 1.91).

Separate analyses of incident colorectal adenomas were directionally consistent with the CRC findings. These analyses included 12,327 participants with a negative baseline sigmoidoscopy, among whom 812 adenomas were detected on repeat screening.

Compared with current light drinkers, former drinkers had significantly lower odds of nonadvanced adenomas (odds ratio [OR], 0.58), but no significant association was observed for advanced adenomas (OR, 1.08; 95% CI, 0.62-1.90). The authors cautioned, however, that overall adenoma case numbers were limited, and estimates for advanced lesions were imprecise.

Educating Patients

Reached for comment, William Dahut, chief scientific officer for the American Cancer Society, told Medscape Medical News that this “very well done, large perspective study clearly demonstrates the significant increased risk of colorectal cancer for those that are heavy drinkers.”

He noted that the nearly twofold increased risk for rectal cancer among heavy drinkers “makes biological sense because the rectum is the area of the body where the toxins produced by alcohol potentially spend the most period of time.” 

Heavy drinkers are at the highest risk, Dahut said, and “for them, screenings are particularly important.”

Even with this growing body of evidence, Levy noted that many patients in America and worldwide “have not been educated yet about the potential carcinogenic dangers of chronic alcohol use.”

Levy recommended that physicians get “accurate social histories about alcohol use” and “spend several minutes educating patients about their increased risk of cancer and liver problems from heavy alcohol use.”

Dahut encouraged health providers to tell patients that the risk for CRC from alcohol is also based on one’s lifetime alcohol consumption, “not simply what they had last weekend.”

Overall, this important research study, along with the Surgeon General’s recent publication about Alcohol and Cancer Risk, will hopefully “encourage physicians to have important conversations about alcohol reduction with their patients,” Levy said. 

The study had no commercial funding. Loftfield, Dahult, and Levy reported no relevant disclosures.

TOPLINE:

New research examining recreational physical activity’s relationship with breast tissue composition, oxidative stress, and inflammation in adolescent girls revealed potential pathways for cancer risk reduction.

METHODOLOGY:

• Recent research shows 12-22% lower risk for breast cancer among highly active women, but the biological mechanisms explaining this remain unclear. Breast tissue composition, particularly mammographic density, is one of the strongest predictors of breast cancer risk, and breast tissue composition tracks across the life course.
• Researchers analyzed data from a population-based urban cohort of 191 Black/African American and Hispanic (Dominican) adolescent girls aged 11-20 years.
• Participants reported organized and unorganized recreational physical activity in the past week, categorized as none, < 2 hours, or ≥ 2 hours.
• Optical spectroscopy measured breast tissue composition through chromophores that are positively (percent water content and percent collagen content) or negatively (percent lipid content) correlated with mammographic breast density.
• Analysis included urinary concentrations of 15-F2-isoprostane for oxidative stress and blood biomarkers of inflammation including TNF-alpha, interleukin-6, and high-sensitivity C-reactive protein.

TAKEAWAY:

• Fifty-one percent of adolescent girls reported no past-week engagement in any type of recreational physical activity, with 73% reporting no participation in organized activities and 66% reporting no participation in unorganized activities.
• Girls engaging in at least 2 hours of organized recreational physical activity vs none showed lower percent water content in breast tissue (beta coefficient, -0.41; 95% CI, -0.77 to -0.05) and lower urinary concentrations of 15-F2-isoprostane (beta coefficient, -0.50; 95% CI, -0.95 to -0.05).
• Higher urinary concentrations of 15-F2-isoprostane were associated with higher percent collagen content in breast tissue (beta coefficient, 0.15; 95% CI, 0.00-0.31).
• No associations were found between recreational physical activity and inflammatory biomarkers, and these biomarkers showed no association with breast tissue composition after adjusting for percent body fat.

IN PRACTICE:

“These findings support that recreational physical activity is associated with breast tissue composition and oxidative stress in adolescent girls, independent of body fat. Additional longitudinal research is needed to understand the implications of these findings regarding subsequent breast cancer risk,” the authors of the study wrote.

SOURCE:

The study was led by Rebecca D. Kehm, PhD, Department of Epidemiology, Mailman School of Public Health, Columbia University, New York City. It was published online in Breast Cancer Research.

LIMITATIONS:

Recreational physical activity was assessed using self-reported data capturing only a 1-week timeframe, which may not fully reflect habitual patterns and is susceptible to measurement error. The cross-sectional nature of the analysis prevented establishing temporal relationships or causal inferences. The relatively small sample size limited statistical power, though researchers were able to detect modest associations. The findings may not be generalizable to populations with different demographics or higher levels of physical activity because recreational physical activity was notably low in this cohort. Additionally, while several validated biomarkers were examined, other mechanisms such as hormonal regulation and insulin sensitivity may also be important for understanding the relationship between adolescent physical activity and breast cancer risk.

DISCLOSURES:

The study received support from the National Institute of Environmental Health Sciences through grants U01ES026122 and P30ES009089, as well as grant ROICA263024 from the National Cancer Institute.

Insights from phase 3 trials presented at the 2025 American Society of Hematology Annual Meeting may expand treatment options for veterans with chronic lymphocytic leukemia (CLL), as discussed by Dr Nicholas Burwick from University of Washington, Seattle.

Dr Burwick begins with the CLL17 trial examining continuous treatment vs fixed-duration therapy in previously untreated patients. The fixed-duration therapy showed noninferior results. Research pertaining to the veterans population in the phase 2 Benefit VA study may offer further insight on these results.

He next discusses the first study comparing the noncovalent BTKi pirtobrutinib to covalent ibrutinib in both treatment-naive patients and those with relapsed/refractory CLL. Pirtobrutinib demonstrated noninferiority in each subgroup. 

Pirtobrutinib was compared to bendamustine plus rituximab in the treatment-naive setting in the next study, showing favorable progression-free survival and a notable trend in overall survival. These two trials could lead to use of a noncovalent BTKi as frontline therapy.

Dr Burwick then turns to 6-year follow-up in the SEQUOIA trial, in which zanubrutinib showed sustained superiority over bendamustine and rituximab. He notes that acalabrutinib is currently the preferred BTKi therapy for veterans with CLL.

Finally, he discusses a study examining combination acalabrutinib and venetoclax, to which obinutuzumab was added either early or late. The rate of infections was significantly higher in the early group, an issue of particular concern in the veterans population.

TOPLINE:

A systematic review of 69 economic evaluations revealed that adjuvant immunotherapy was cost-effective in 58% of studies, with higher Quality-Adjusted Life-Year gains reported in 91% of cases. Cost-effectiveness varied significantly by cancer type, treatment strategy, and healthcare system context, with industry-funded studies more likely to report favorable outcomes.

METHODOLOGY:

• Multiple phase 3 trials have shown improved survival and reduced recurrence with adjuvant immunotherapy in various cancers. But the high cost of immunotherapy treatments, often exceeding $100,000 per patient, has raised questions about their economic value and affordability across different healthcare systems.
• Researchers conducted a systematic review of 69 economic evaluations published between January 2015 and January 2025, focusing on adjuvant immunotherapy across various cancer types.
• Analysis included studies from PubMed, Embase, Scopus, Web of Science, and Cochrane Library, with most evaluations conducted in the US (26 studies) and China (20 studies).
• Quality assessment utilized the Criteria for Health Economic Quality Evaluation tool, evaluating 48 attributes across methodologic and reporting quality dimensions.
• Markov modeling dominated the analytical approach (46 studies [67%]), with EuroQol Five-Dimensions being the most commonly used health utility instrument (56 studies [81%]).

TAKEAWAY:

• Of 69 studies analyzed, 58% concluded that adjuvant immunotherapy was cost-effective, with stronger evidence in non-small cell lung cancer and melanoma, particularly in early-stage and high-risk populations.
• Industry-funded studies more frequently reported cost-effective outcomes (17 of 20 studies [85%]) than nonindustry funded studies (13 of 28 studies [46%]).
• Higher Quality-Adjusted Life-Year/Life-Year gains were consistently reported in the adjuvant immunotherapy group (63 studies [91%]), especially for non-small cell lung cancer and combination regimens.
• Cost-effectiveness results varied significantly by cancer type, model assumptions, drug pricing, funding organizations, and country-specific willingness-to-pay thresholds.

IN PRACTICE:

“From a policy standpoint, the findings of this systematic review support the use of structured, context-specific health technology assessment frameworks to evaluate adjuvant immunotherapies. For health systems under financial constraints, prioritizing subgroups with the highest absolute benefit may be a viable approach to ensure sustainable access,” the authors of the review wrote.

SOURCE:

The systematic review was led by Rashidul Alam Mahumud, PhD, MCncrSc, MPH, MSc, Health Economics and Health Technology Assessment Unit, National Health and Medical Research Council Clinical Trials Centre, The University of Sydney in Camperdown, Australia. It was published online on January 22 in JAMA Oncology.

LIMITATIONS:

The methodologic heterogeneity across studies presents a significant limitation, with variations in time horizons, discounting methods, survival data extrapolation, and health utility measurements affecting result comparability. Geographic distribution primarily focused on high-income countries, limiting generalizability to low- and middle-income settings. Few evaluations incorporated adaptive pricing schemes or managed entry agreements that increasingly influence clinical reimbursement decisions.

DISCLOSURES:

Mahumud had full access to all study data and takes responsibility for data integrity and analysis accuracy. The authors reported having no relevant conflicts of interest.

TOPLINE:

A systematic review of 69 economic evaluations revealed that adjuvant immunotherapy was cost-effective in 58% of studies, with higher Quality-Adjusted Life-Year gains reported in 91% of cases. Cost-effectiveness varied significantly by cancer type, treatment strategy, and healthcare system context, with industry-funded studies more likely to report favorable outcomes.

METHODOLOGY:

• Multiple phase 3 trials have shown improved survival and reduced recurrence with adjuvant immunotherapy in various cancers. But the high cost of immunotherapy treatments, often exceeding $100,000 per patient, has raised questions about their economic value and affordability across different healthcare systems.

The Centenarian Program at the US Department of Veterans Affairs (VA) has expanded to begin honoring veterans for special occasions, such as birthdays, as well as veterans with very limited life expectancy. 

Initially launched in 2020 as a special initiative that awarded commemorative coins to American heroes aged 100 years, the program recognizes each individual’s service to the country. 

“This program symbolizes the commitment that we promise to our veterans,” said Center for Development and Civic Engagement (CDCE) Chief Dennis Montgomery in West Palm Beach, Florida. “They are never forgotten. No matter the years since time of service, the VA will always honor and remind them of the gratitude we proudly hold in our hearts for their bravery and sacrifice.”

Eligible veterans receive a personalized letter from the VA Secretary, a commemorative coin, and public recognition from their local VA facility, which often includes a celebration. To be eligible, veterans must be enrolled and receiving care through the VA health care systems. 

Coins are customized for each veteran with unique attributes, including the veteran’s name, branch of service, military occupational specialty, and years of service.

“I originally learned of the program in 2022, and I explored the possibilities to expand the reach of active engagement from the Center of Development and Civic Engagement and the VA Secretary’s office,” said Saraswathy Battar, MD, a geriatrician at the Thomas H. Corey VA Medical Center (VAMC) Community Living Center in West Palm Beach, who oversaw the program until her retirement in November 2025. The program is currently administered by the office of VA Secretary Douglas Collins.

Between August 2022 and October 15, 2025, 1182 centenarian veterans and 285 special recognition honorees received commemorative coins. 

“As our local veteran population grows within the centenarian coin eligibility criteria,” Montgomery said, “I know this program will continue to grow as well and gain more popularity to honor our veterans as they have earned and deserved.”  

The VA conducts outreach through local health care professionals to identify veterans eligible for the program. This allows for veterans admitted to the VA to be identified, leading to activation of the ceremony process. 

If veterans are in declining health, they become eligible to receive recognition at age 95, Montgomery said.

TOPLINE:

Spleen volume larger than the 99th percentile was associated with an 11-fold increased risk for hematologic cancer compared with normal volumes, with 5-year risks as high as 46% among men aged 70 years or older. Significant risks for cirrhosis and liver cancer were also seen.

METHODOLOGY:

• Splenomegaly is often detected incidentally during imaging, but guidelines vary as to the threshold that should prompt evaluation — ranging from a spleen length of 120 mm to 150 mm. However, up to 21% of healthy individuals have spleen lengths > 120 mm, which could lead to unnecessary follow-up of low-risk patients.
• Researchers used data from two general population cohorts to evaluate the relative and absolute risks for hematologic cancer and liver disease (two common causes of spleen enlargement) among individuals with incidentally detected splenomegaly. They included 8459 Danish adults (57% female; median age, 61 years) and 38,607 UK adults (51.9% female; median age, 65 years) who underwent CT or MRI scans as part of study procedures.
• Spleen length and volume measurements were available from the Danish cohort, while only spleen volume was available from the UK group.
• Participants were followed for a median of 5 years after imaging to assess the incidence of hematologic cancers (both cohorts) and cirrhosis and liver cancer (UK cohort only). Hazard ratios were adjusted for age, sex, smoking status, alcohol consumption, comorbidities, and C-reactive protein levels.

TAKEAWAY:

• In the Danish cohort, the relative risk for any hematologic cancer was significantly increased among individuals with spleen lengths above the 99th percentile (≥ 135 mm) compared with those with spleen lengths in the 26th-74th percentile (hazard ratio [HR], 5.11; P < .001). Among individuals with a spleen length ≥ 140 mm, absolute 5-year risks reached 23% for men aged 70 years or older and 12% for women in that age group.
• Risks were even more pronounced for Danish adults with a spleen volume above the 99th percentile — > 433 mL. Relative to the 26th-74th percentile, their risk for any hematologic cancer was 11-fold higher (HR, 11.08; P < .001). Among people with a spleen volume ≥ 500 mL, 5-year risks reached 46% for men aged 70 years or older and 27% for women in that age group.
• Findings were similar in the UK cohort. Among individuals with a spleen volume above the 99th percentile (> 386 mL), the risk for hematologic cancer increased nearly 12-fold (HR, 11.82; P < .001). With a spleen volume ≥ 500 mL, 5-year risks reached 21% for men aged 70 years or older and 18% for women in that age group. Relative risks were also elevated — by 1.55-2.94 — among individuals in the 75th-99th percentile (199 mL-386 mL).
• The risks for liver disease began to rise substantially at a spleen volume ≥ 400 mL. Absolute 5-year risks for cirrhosis reached 10.8% for men and 9.3% for women aged 70 years or older with a spleen volume ≥ 500 mL. For liver cancer, 5-year risks reached 3.2% and 1.2% for men and women in that age group with a spleen volume ≥ 400 mL.

IN PRACTICE:

“To our knowledge, no previous studies have examined risk of hematologic cancers by spleen length or volume in incidentally detected splenomegaly,” the authors of the study wrote. “Risk was moderately increased at spleen length of 130-139 mm or spleen volume of 400-499 mL, where diagnostic workup may be considered, and more pronounced at spleen length of 140 mm or greater or spleen volume of 500 mL or greater, supporting that diagnostic workup may likely be relevant.”

They stressed, however, that the study participants were asymptomatic, and the underlying reason for imaging should always be considered.

Tightened Medicaid eligibility rules under the 2025 Budget Reconciliation Bill could result in more than 1 million missed cancer screenings within 2 years and over 150 avoidable cancer deaths, new findings suggested.

“Clinicians should be genuinely concerned,” corresponding author Adrian Diaz, MD, MPH, a surgical oncology fellow at the University of Chicago, Chicago, told Medscape Medical News. “These projections suggest that Medicaid eligibility restrictions are likely to translate into delayed diagnoses, more advanced disease at presentation, and worse outcomes.”

The new law, which significantly reduces federal Medicaid funding, introduces mandatory work or community-engagement requirements for working-age adults as well as more frequent recertification starting in 2027.

In the study, a Research Letter published online on January 8 in JAMA Oncology, Diaz and Sarah Shubeck, MD, also from the University of Chicago, drew on data from Arkansas to model how these 2025 federal Medicaid eligibility restrictions could lead to loss of Medicaid coverage and consequently missed cancer screenings, especially in states that expanded Medicaid.

Diaz and Shubeck then paired coverage losses with state-level self-reported screening prevalences and estimated incident breast, colorectal, and lung cancers using 2-year risks.

In the first 2 years after implementation, the researchers predicted that 7.5 million adults (range, 5.0-10.8 million) will lose Medicaid coverage due to the new provisions.

This coverage loss will lead to an estimated 405,706 missed mammograms, 679,745 missed colorectal screenings, and 67,213 missed lung cancer screenings.

As a result, 1055 breast cancers, 748 colorectal cancers, and 538 lung cancers will go undetected, with excess deaths totaling 155 — 70 for breast, 50 for colorectal, and 35 for lung cancers.

Predicted missed screenings and related cancer outcomes varied considerably by state, with missed screening rates generally lower in states that didn’t expand Medicaid.

“Importantly, our estimates focus on missed screening and do not account for patients already undergoing cancer treatment whose coverage could be interrupted, meaning the real-world impact is likely larger,” Diaz said.

Farhad Islami, MD, PhD, senior scientific director of Cancer Disparity Research at the American Cancer Society, said the estimated coverage losses are “consistent with the number” — 7.8 million — “estimated by the nonpartisan Congressional Budget Office.”

Islami also stressed that the harm caused by the new restrictions would be “far greater” than what the study reports, with coverage losses leading to delays in care seeking for cancer symptoms of all kinds “and consequently, delayed diagnosis for many more cancer cases.”

“Moreover,” he added, “the restrictions can reduce the utilization of preventive care (eg, counselling and pharmacotherapy for smoking cessation among people who smoke, counselling for reducing weight, and so on) and receipt of guideline-concordant cancer treatments among those who will lose Medicaid coverage.”

In Diaz’ view, clinicians can help mitigate the adverse effects of the new provisions.

“For example, proactively identifying patients at risk of coverage loss, engaging financial counselors and social workers early, and connecting uninsured or underinsured patients to safety-net screening and treatment programs,” he said. “At a systems level, clinicians also have an important role in documenting and communicating these downstream clinical consequences to health systems and policymakers.”

In the first 2 years after implementation, the researchers predicted that 7.5 million adults (range, 5.0-10.8 million) will lose Medicaid coverage due to the new provisions.

This coverage loss will lead to an estimated 405,706 missed mammograms, 679,745 missed colorectal screenings, and 67,213 missed lung cancer screenings.

As a result, 1055 breast cancers, 748 colorectal cancers, and 538 lung cancers will go undetected, with excess deaths totaling 155 — 70 for breast, 50 for colorectal, and 35 for lung cancers.

Predicted missed screenings and related cancer outcomes varied considerably by state, with missed screening rates generally lower in states that didn’t expand Medicaid.

“Importantly, our estimates focus on missed screening and do not account for patients already undergoing cancer treatment whose coverage could be interrupted, meaning the real-world impact is likely larger,” Diaz said.

Farhad Islami, MD, PhD, senior scientific director of Cancer Disparity Research at the American Cancer Society, said the estimated coverage losses are “consistent with the number” — 7.8 million — “estimated by the nonpartisan Congressional Budget Office.”

Islami also stressed that the harm caused by the new restrictions would be “far greater” than what the study reports, with coverage losses leading to delays in care seeking for cancer symptoms of all kinds “and consequently, delayed diagnosis for many more cancer cases.”

“Moreover,” he added, “the restrictions can reduce the utilization of preventive care (eg, counselling and pharmacotherapy for smoking cessation among people who smoke, counselling for reducing weight, and so on) and receipt of guideline-concordant cancer treatments among those who will lose Medicaid coverage.”

In Diaz’ view, clinicians can help mitigate the adverse effects of the new provisions.

“For example, proactively identifying patients at risk of coverage loss, engaging financial counselors and social workers early, and connecting uninsured or underinsured patients to safety-net screening and treatment programs,” he said. “At a systems level, clinicians also have an important role in documenting and communicating these downstream clinical consequences to health systems and policymakers.”

Tightened Medicaid eligibility rules under the 2025 Budget Reconciliation Bill could result in more than 1 million missed cancer screenings within 2 years and over 150 avoidable cancer deaths, new findings suggested.

“Clinicians should be genuinely concerned,” corresponding author Adrian Diaz, MD, MPH, a surgical oncology fellow at the University of Chicago, Chicago, told Medscape Medical News. “These projections suggest that Medicaid eligibility restrictions are likely to translate into delayed diagnoses, more advanced disease at presentation, and worse outcomes.”

The new law, which significantly reduces federal Medicaid funding, introduces mandatory work or community-engagement requirements for working-age adults as well as more frequent recertification starting in 2027.
