Study: Most respond well to genetic testing results

People at high risk for psychological distress respond positively to receiving results of personalized genetic testing, according to new research at Washington University School of Medicine in St. Louis. More than 60 percent of subjects in the genetic study wanted information about their test results, and 95 percent said they appreciated receiving the information, regardless of whether the results were good or bad news.

Poor colonoscopy prep hides pre-cancerous polyps

What happens on the day before a colonoscopy may be just as important as the colon-screening test itself. Gastroenterologists at Washington University School of Medicine in St. Louis have found that when patients don’t adequately prep for the test by cleansing their colons, doctors often can’t see potentially dangerous pre-cancerous lesions.

James Fleshman, MD, is a highly regarded surgeon known for developing laparoscopic techniques for colorectal surgery. In a landmark clinical trial, his research helped to establish that laparoscopic surgery is as safe and effective as conventional surgery for removing colon tumors.

Scientists identify cells in fruit fly gut that start tumors

Tumor growth can start from stem cells in the gut, say researchers studying fruit flies at the School of Medicine. They found that tumors can grow from adult stem cells that have lost a specific tumor-suppressor gene. The gene, Apc, has previously been implicated in human gastrointestinal cancers, including colon cancer.
