Adenoma detection rate benchmarks are currently set at 25 percent for male and 15 percent for female colonoscopy patients. A new study published in The New England Journal of Medicine suggests that these benchmarks may need to be higher, according to a Gastroenterology & Endoscopy News report.
Researchers from Kaiser Permanente Northern California analyzed 264,000 colonoscopies performed by 136 gastroenterologists between 1998 and 2010. Researchers found 712 cases of interval colorectal cancer. Of the interval cases, 147 deaths occurred. Here are six things to know about the study.
• The median interval between colonoscopy and subsequent colorectal cancer diagnosis was 39 months.
• Physicians' ADRs ranged from 7.4 percent to 52.5 percent.
• ADRs for male patients ranged from 9.7 percent to 60.5 percent.
• ADRs for female patients ranged from 3.9 percent to 45.9 percent.
• The risk of interval cancer diagnosis was 0.52 for patients of physicians in the highest quintile of ADR compared to physicians in the lowest quintile.
• For each 1 percent increase in ADR, the corresponding risk of interval cancer decreases by 3 percent.
"As we continue to build evidence that colonoscopy with polypectomy reduces CRC incidence, and even more importantly, reduces mortality from CRC, the focus will turn to ways to enhance the effectiveness of the procedure," said Peter P. Stanich, MD, assistant professor at The Ohio State University in Columbus, according to the report.
