Jason A Zell

Jason A. Zell is an Associate Professor in the Division of Hematology and Oncology at the University of California, Irvine School of Medicine. He serves as Program Director of the Hematology/Oncology Fellowship Training Program and Vice Chief for Academic Affairs in his division. His research focuses on colorectal cancer treatment outcomes, adjuvant chemotherapy timing, and the impact of lifestyle factors like NSAID use and meat consumption on cancer survival. Dr. Zell’s work utilizes large databases like the National Cancer Database (NCDB) to analyze treatment efficacy and disparities in care.

His studies have examined how delays in adjuvant chemotherapy correlate with reduced survival in rectal cancer patients and how pre-diagnosis NSAID use may improve survival in low-meat consumption groups. He has also contributed to understanding classification changes in lung cancer subtypes and their epidemiological implications. Dr. Zell’s research emphasizes evidence-based practice and disparities in oncology care, with a focus on translating findings into clinical guidelines.
