Research conducted at Roswell Park Comprehensive Cancer Center shows that the types of T cells circulating in the blood of patients with recurrent ovarian cancer may predict the likelihood that their disease will respond to an anti-PD1 immunotherapy. The findings, which grew out of a phase 2 clinical trial led by Emese Zsiros, MD, PhD, FACOG, Chair and Director of Research, Department of Gynecologic Oncology, will be highlighted at the Society of Gynecologic Oncology (SGO) Annual Meeting on Women’s Cancer, March 25-28 in Tampa, Florida.
