Jeffrey K. Lee, MD, MPH, 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.

Current Position(s):

  • Research Scientist I, Division of Research, Kaiser Permanente Northern California

      Comparison of Survival Rates Across Racial/Ethnic Groups Among Young Adults Diagnosed with Early-Onset Colorectal Cancer in a Large, Community-Based Population.

      This study will examine racial differences in overall survival among young adults 50 years of age diagnosed with early-onset colorectal cancer in a large, community- based, fully insured population with access to complete primary and specialty care to identify differences in risk factors, access to care, and treatment effectiveness and adherence.

      COmprehensive risk Model for Predicting Advanced neoplasia on Surveillance Study (COMPASS)

      The goals of this project are to develop and validate a colorectal neoplasia risk prediction model among average-risk patients who underwent a baseline colonoscopy; estimate the risk of advanced neoplasia among patients with newly diagnosed Lynch Syndrome; and develop and validate a colorectal neoplasia risk prediction model among patients with newly diagnosed Lynch Syndrome.

      Rates and Risk Factors of Post-Colonoscopy Colorectal Cancer in a Large, United States Population-based Cohort Study

      Colorectal cancer (CRC) is the third leading cause of cancer death in the United States. Colonoscopy can reduce CRC incidence and deaths through removal of precancerous adenomatous polyps (adenomas) and detection of cancer at an earlier, more treatable stage. However, some patients develop CRC after a colonoscopy in which no cancer is diagnosed. The World Endoscopy Organization (WEO) defines post-colonoscopy colorectal cancers (PCCRCs) as CRC diagnosed 6 months after a colonoscopy that did not detect cancer. PCCRC is poorly understood as there is uncertainty about how often these cancers occur, their likely etiologies, the risk factors for these cancers, and whether they are more lethal than detected CRCs. To address these uncertainties, the WEO published a consensus statement to provide comprehensive guidance for the investigation of PCCRC cases. Their recommendations include a standardized definition for PCCRC, a defined method for calculating PCCRC rates, and standardized methods for performing qualitative reviews of cases to determine their likely etiology. The primary goal of the proposed study is to use recently published WEO methods to determine PCCRC rates, the likely etiologies for these cancers, their risk factors, and prognoses for PCCRC in the large integrated healthcare setting of Kaiser Permanente Northern California (KPNC).

      De-Implementation of Outdated Colonoscopy Surveillance Interval Recommendations among Patients with Low-Risk Adenomas (DESIRE)

      Recent guidelines have extended surveillance intervals for patients with low-risk adenomas from 5 years to 10. However, it remains unclear how to implement this change. In a pragmatic randomized 2-arm study of 1,000 patients with a history of low-risk adenomas and a standing 5-year surveillance recommendation, we will compare the effectiveness of secure messaging versus mailed outreach for adopting the new 10-year surveillance interval recommendation, continuing with the standing 5-year recommendation, or requesting a provider encounter (e.g., clinic or virtual visit) for shared decision making.

      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.
