Jeffrey K. Lee, MD, MAS, is a Research Scientist I at the Kaiser Permanente Northern California Division of Research and an attending gastroenterologist at Kaiser Permanente San Francisco Medical Center. His clinical focus is in general gastroenterology, colorectal cancer prevention, and hereditary gastrointestinal cancer syndromes. His research interests include: colorectal cancer prevention, gastrointenstinal cancer prevention, pharmacoepidemiology, diagnostic testing for gastrointestinal cancers, and improving the quality and safety of endoscopy and colonoscopy. He holds a Bachelor of Arts from the University of California, Berkeley, a Masters in Clinical Research from the University of California, San Diego, and a Doctorate in Medicine, also from UCSD. After medical school, he completed an internal medicine residency at UCSD; and a gastroenterology fellowship at the University of California, San Francisco. Prior to joining Kaiser Permanente, he practiced gastroenterology at UCSF Medical Center for several years.

Studies

Optimizing Long-Term Post-Polypectomy Surveillance for Colorectal Cancer Prevention Using a Prediction Rule Developed from a Large, Community-Based Cohort

Screening has been shown to reduce colorectal cancer incidence and mortality. However, screening has resulted in a growing cohort of patients with adenomatous polyps (adenomas), and little is known about effectively managing their post-polypectomy surveillance. With limited data available in the literature to determine the appropriate timing and frequency of follow-up colonoscopy for patients after adenoma removal, recommendations for post-polypectomy surveillance from our national guidelines have been imprecise at best. To fill this knowledge gap, this project aims to: 1) determine the long- term colorectal cancer risk in patients after colonoscopic polypectomy in a very large “real world” community-based population; 2) identify patient-, polyp-, and exam-related risk factors associated with incident colorectal cancer in these patients; and 3) develop a risk prediction model that will identify post- polypectomy patients at high and low risk for developing subsequent colorectal cancer.
