Patients with a confirmed diagnosis of High-grade serous EOC, primary peritoneal cancer, or fallopian tube cancer 3. Patients willing to submit a neutral buffered formalin-fixed paraffin-embedded (FFPE) block of tumor tissue for storage or a newly prepared FFPE thin section with a designated glass slide 4. Enrollment Criterion A only: Patients with platinum-resistant disease: a. Patients who have only had 1 line of platinum based therapy must have received at least 4 cycles of platinum, must have had a response (CR or PR) and then progressed between > 3 months and <= 6 months after the date last dose of platinum b. Patients who have received 2 or 3 lines of platinum therapy must have progressed on or within 6 months after the date of the last dose of platinum. Note: Progression should be calculated from the date of the last administered dose of platinum therapy to the date of the radiographic imaging showing progression Note: Patients who are platinum-refractory during front-line treatment are excluded (see exclusion criteria). 5. Enrollment Criterion B only: Patients with platinum-sensitive disease: a. Patients undergoing platinum-containing chemotherapy in combination with bevacizumab after platinum-sensitive recurrence 6.

Patients who are able to sign and date the Informed consent form prior to enrollment in the study
