Group Profile

Our research group's central purpose is to reduce the burden of gastrointestinal cancers, including colorectal cancer, across all populations. This work includes utilizing large-scale healthcare and cancer registry data, such as from the Department of Veterans Affairs Healthcare System, to examine the epidemiology of gastrointestinal cancers, as well as prospective randomized trials of strategies to increase colorectal cancer screening rates among underserved populations. Current funded initiatives include a National Cancer Institute-funded R37 award supporting a large-scale case-cohort study to determine whether exposure to surveillance colonoscopy after colorectal polypectomy reduces colorectal cancer incidence or mortality (Gupta, PI), as well as a National Cancer Institute Cancer Moonshot Accelerating Colorectal Cancer Screening and follow-up through Implementation Science (ACCSIS) award to conduct a 4-year prospective randomized trial of regional implementation of a mailed outreach program offering the fecal immunochemical test for colorectal cancer screening, as well as in-clinic best practices for promoting colorectal cancer screening and abnormal test follow up at multiple Federally Qualified Health Center systems (Martínez, Gupta, Casteñeda, MPI).

Future funded work will include a large-scale cohort study to evaluate the risks vs. benefits of exposing older adults age >75 years with prior polypectomy to colonoscopy surveillance. Our work has informed national practice guidelines, such as the US Multi-Society Task Force recommendations for follow-up after colonoscopy with polypectomy, as well as guidance by the Centers for Disease Control and others on strategies for improving colorectal cancer screening participation rates. Key collaborators at UC San Diego include Drs. Lin Liu, Shailja Shah, and Elena Martinez, among others. Our group has supported the careers of a range of clinical scientists in training, from undergraduate students through post-doctoral fellows.
