Second Sigmoid Study Ups Early Cancer Detection
Repeat flexible sigmoidoscopy increased detection of colorectal cancer or advanced adenoma by one-fourth in women and one-third in men, according to the latest results from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial.
Among nearly 78,000 enrollees, the second flexible sigmoidoscopy exam increased the screening yield by 26% in women, 34% in men, and 32% overall, reported Joel L. Weissfeld, MD, MPH, from the University of Pittsburgh Medical Center, and colleagues in the Journal of the National Cancer Institute.
