Research Abstract
Peritoneal carcinomatosis is an extremely challenging clinical problem and is associated with dismal prognosis. One of the current challenges with peritoneal carcinomatosis is lack of sensitive markers for early diagnosis and prognostication. Dr. Senthil's basic science research work is focused on developing a liquid biopsy by utilizing blood- based Exosomal bio-markers in patients with peritoneal carcinomatosis to serve as a predictive and prognostic tool. The advantage of liquid biopsy is that it's a non-invasive tool that has the potential to replace tumor biopsies and invasive diagnostic testing to detect cancer.
On the clinical side, she conducts investigator-initiated clinical trials to change the treatment paradigm of peritoneal carcinomatosis. A phase-II clinical trial to test the efficacy of intraperitoneal chemotherapy in gastric peritoneal carcinomatosis is currently under review to be opened at UCI.
