Colorectal Cancer

Healio Gastroenterology and Liver Disease presents the following reports on the most recent research in colorectal cancer and screening for colorectal polyps.

Using a multitarget stool DNA test helped improve the sensitivity for detecting precancerous colorectal lesions compared with fecal immunochemical tests alone in an average-risk population, according to study results.

Low-volume, split-dose bowel preparations were just as effective as high-volume preps with the added benefit of being better tolerated by patients, according to the results of a metanalysis.

Omega-3 supplementation of 1 g per day did not appear to reduce the risk for colorectal cancer precursors among the average-risk U.S. population, according to results of an ancillary study of the randomized VITAL trial published in JAMA Oncology.

Individuals are more likely to participate in colorectal cancer screening if their family physician has undergone screening, according to study results.

Laparoscopic resection conferred a long-term survival advantage compared with open hepatectomy for patients with liver metastases from colorectal cancer, according to findings from a patient-level meta-analysis published in Annals of Surgery.

SAN ANTONIO — A higher serrated polyp detection rate was associated with a decreased incidence of post-colonoscopy colorectal cancer, according to study results presented at the American College of Gastroenterology Annual Meeting.

A video Will Smith recently posted about his colonoscopy in which he walked viewers through the entire process earned praise from physicians for helping to normalize the procedure. It was the week’s top story in gastroenterology.

SAN ANTONIO — The increased prevalence of advanced adenoma and clinically significant serrated polyps was similar among age groups on both sides of age 50 years, suggesting that screening at 45 years optimizes colorectal cancer prevention, according to study results presented at the American College of Gastroenterology Annual Meeting.

SAN ANTONIO — Obesity and underweight were associated with worse colorectal cancer outcomes, recurrence and mortality, compared with normal weight, according to results of a meta-analysis presented at the American College of Gastroenterology Annual Meeting.
