Author Interviews, Brigham & Women's - Harvard, Colon Cancer, JAMA, Omega-3 Fatty Acids / 26.11.2019 Interview with: MINGYANG SONG, MD, ScD Assistant Professor, Epidemiology Harvard T.H. Chan School Of Public Health Assistant Professor of Medicine Clinical and Translational Epidemiology Unit Massachusetts General Hospital What is the background for this study? Response: Increasing data indicate that high intake of omega-3 fatty acid may reduce the risk of colorectal cancer. Since effects of nutritional factors on risk of cancer, a slow-developing disease, typically emerge only after several years, it is useful to study the effect of preventive agents on cancer precursors such as colorectal polyps. Colorectal polyps are small growths on the lining of the colon or rectum. Most polyps are harmless, but some can become cancerous. (more…)
AACR, Author Interviews, Colon Cancer / 20.03.2018 Interview with: Darren D. Browning, PhD | Professor Department of Biochemistry and Molecular Biology, Medical College of Georgia at Augusta University Georgia Cancer Center, Augusta, Georgia 30912-2100 What is the background for this study? What are the main findings? Response: Cancer of the colon and rectum is one of the most commonly diagnosed and has a high mortality because it is often identified at an advanced stage. In the United States the average overall risk of having to deal with this disease at some point is around one in twenty-five, but the risk is much higher for people who have previously had polyps removed or if a close relative was diagnosed with colon cancer. The risk is even higher for patients with inflammatory bowel disease or heritable disorders such as familial adenomatous polyposis and lynch syndrome. While chemoprevention is clearly warranted, there are currently no drugs available that can reduce the risk for those predisposed to colorectal cancer. Previous work from our laboratory has shown that drugs like sildenafil that inhibit phosphodiesterase 5 (PDE5), have a profound effect on the epithelial lining of the intestine. Our recent work has shown that these drugs can prevent intestinal cancers in two different mouse models of human disease. While this class of drugs is best known for treating erectile dysfunction, due to a low side-effect profile they are also prescribed for long-term daily use to treat pulmonary arterial hypertension (PAH) and benign prostate hyperplasia (more…)

Jenifer I Fenton Assistant Professor Department of Food Science and Human Nutrition Michigan State University East Lansing, MI Interview with: Jenifer I Fenton Assistant Professor Department of Food Science and Human Nutrition Michigan State University East Lansing, MI 48824 What are the main findings of the study? Dr. Fenton: This was a cross-sectional study, and thus, a snapshot in time. Although it cannot infer cause or temporality of obesity and colon polyp risk in men, it does show that obese men were more likely to have a polyp than their lean counterpart. In addition, there were serum biomarkers also associated with this risk. This could eventually lead to future blood tests to identify individuals at greater risk for polyps and inform screening recommendations. (more…)
