we collected fecal samples from 382 female patients from Zhejiang Cancer Hospital in China, including 239 patients with OTs (148 patients with OC and 91 with BOTs), 90 patients with OBTs, and 53 with HCs. All subjects provided written informed consent, and the study was approved by our local ethics committee. The following patients were excluded: those who did not sign a consent form and those with other malignant tumors. Stool samples were freshly collected and immediately frozen for follow-up analysis. Subject clinical data were collected by consulting medical records, including factor such as age, and FIGO stage.
