Validation of Tumor-Infiltrating T-Cells as a Biomarker for Advanced Epithelial Ovarian Cancer
This research study is looking at tumor tissue samples from patients who have undergone surgery for advanced stage III or stage IV ovarian epithelial cancer. Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn how tumor infiltrating T cells can predict how patients will respond to treatment.
• Diagnosis of stage III or IV ovarian epithelial cancer and enrolled on Gynecologic Oncology Group (GOG)-0136 and a GOG front-line platinum/taxol chemotherapy trial (GOG-0114, GOG-132, GOG-0158, or GOG-0162)
• Must have fixed and paraffin-embedded tissue from primary surgery available from 1 of the following sources:
‣ Patients enrolled on GOG-0136 and a GOG front-line platinum/taxol chemotherapy trial(GOG-0114, GOG-0132, GOG-0158, and GOG-0162)
⁃ Patients who have had either optimal or suboptimal cytoreductive surgery
⁃ Patients for whom adequate demographic data, including major prognostic factors and follow-up information, were collected
• Evaluable patients must have had measurable or nonmeasurable disease
• Demographic and follow-up data available
