BACKGROUND: We herein retrospectively analyzed the clinicopathologic features from a large cohort of GAS patients to provide real-world evidence for optimizing the diagnosis and treatment. RESEARCH DESIGN AND METHODS: One hundred and fifty-seven GAS patients from three hospitals were recruited for analysis. We extracted clinical and pathologic information from patient medical records and performed regular follow-up. Logistic regression and Kaplan - Meier analyses were conducted to identify the prognostic factors. RESULTS: 31.2% exhibited stage I tumor, and 11.5%, 33.1%, and 24.2% manifested tumors at stages II, III, and IV, respectively. For the entire group, the median progression-free survival (PFS) and overall survival (OS) were 22 and 33 months, respectively. Multivariate analysis showed tumor stage and ovarian metastasis were predictors for PFS
and that ovarian metastasis and small tumor diameter were independent prognostic factors for OS. We determined an abnormal elevation of tumor abnormal protein (TAP) in 76% GAS patients, which could serve as a sensitive marker for tumor recurrence/metastasis. CONCLUSIONS: We demonstrated that ovarian metastasis and FIGO stage (including tumor diameter) were independent prognostic predictors for GAS patients. Moreover, we were the first to report that TAP constituted a potent marker for GAS surveillance, thus warranting further investigation.
