The goal of this non-randomized prospective study is to use 18F-EF5-PET/CT imaging to identify and locate intraabdominal hypoxic ovarian cancer lesions. With targeted surgical sampling, precisely obtain hypoxic and potentially chemoresistant cancer tissue for our analyses and identify key molecular differences between hypoxic and non-hypoxic tumors within the same patient.
A portion of advanced stage EOC are inoperable at diagnosis and can be treated with neoadjuvant chemotherapy (NACT) before surgery. This approach offers a unique opportunity to study how hypoxic tumor areas respond to treatment.

Experimental: PDS
18F-EF5 PET/CT and 18F-FDG PET/CT scan prior to primary cytoreductive surgery and targeted sample collection during primary cytoreductive surgery
|
Device: Imaging with 18F-EF5 PET/CT
Both 18F-FDG PET/CT and 18F-EF5 PET/CT imaging are performed in 1) preoperative work-up to clarify the disease distribution, 2) before IDS to evaluate treatment response to NACT (IDS arm); targeted samples from hypoxic and non-hypoxic tumors are collected during surgery
Other Name: Collection of targeted samples during surgery

Experimental: IDS
18F-EF5 PET/CT and 18F-FDG PET/CT scans prior to diagnostic laparoscopy and after neoadjuvant chemotherapy before interval cytoreductive surgery . Targeted sample collection during diagnostic laparoscopy and interval cytoreductive surgery |
