A Pilot Study Investigating the Effect of Chemotherapy on the Tumoral Immunoprofile of Gynecologic Cancers

This is a single-institution, non-interventional prospective observational study allowing for specimen and data collection. All participants will receive standard of care surgery and chemotherapy, determined by the gynecologic oncologist and per institutional protocols. Patients with a presumed diagnosis of an eligible gynecologic malignancy (epithelial ovarian, fallopian tube, primary peritoneal, or uterine endometrial cancer) who are being considered for neoadjuvant chemotherapy prior to confirmatory biopsy will be given the option to enroll on this study. Patients will undergo standard biopsy or endometrial curettage to confirm diagnosis. Additional tumor tissue for research purposes will be collected at the time of biopsy (if safely available). Patients who are undergoing diagnostic or therapeutic paracentesis will have the option to consent to allow excess ascites to be evaluated in this research protocol. Additionally, a research blood sample will be collected on the same day as the biopsy/curettage. After confirmation of diagnosis, chemotherapy administration will proceed per standard institutional protocol and surgical planning will be performed by the treating gynecologic oncologist. Excess tumor tissue and ascites from the cytoreductive surgery will be collected for immune profiling. An additional vial of blood for research will be collected within 3 days prior to surgery. Post-surgical treatment and chemotherapy will proceed per standard procedures. After completion of post-surgical adjuvant therapy, an additional vial of blood for research will be collected (at next scheduled clinic visit).
