Research/ Clinical Interests

Dr. Jocelyn Chapman brings expertise in computational genomics to the gynecologic oncology division and collaborates with UCSF cancer center researchers to understand the genetic vulnerabilities in gynecologic cancer that can be exploited for therapeutic targeting. Her current work focuses on the molecular signals in circulation that might be used to detect early ovarian cancers. She has a clinical trial ongoing to gain insights into these molecular fingerprints with a goal to develop a non-invasive ovarian cancer detection test. She also collaborates with the immuno-oncology program to understand the immunologic responses induced by mutationally complex tumors and how this signaling interacts with the mutational processes driving tumorigenesis in gynecologic malignancies. Understanding the immune signaling between gynecologic cancer cells and their microenvironment components will help illuminate how anti-tumor immune signaling is propagated, how it may be short-circuited and may reveal mechanisms to control or interrupt this signaling for therapeutic benefit.

Dr. Chapman's clinical research interests involve optimizing the rational and economical delivery of medical care to our gynecologic oncology patients. To this end, she has successfully implemented post-operative immunonutrition with a demonstrable reduction in post-operative wound complications and post-surgical pathways with a demonstrable reduction in hospital length of stay. She has also improved peri-operative education to facilitate improved recovery and patient satisfaction. Current efforts are focused at developing a tool to improve our post-operative opioid prescribing patterns to minimize the impact of opioid over prescribing in our community. Her research has been published in Science Immunology, Clinical Cancer Research, Gynecologic Oncology, Journal of the National Comprehensive Cancer Network and Nature Biotechnology.
