Table 3.

Prognostic factors for long-term survival. The Cox regression analysis was stratified by the histological type/grade of the ovarian cancers. Covariates were patient age (≥ versus <55), FIGO (IIA and IIIB versus IIIc versus IV), residual disease after surgery (yes versus no), peritoneal carcinosis (yes versus no), progression-free interval (< versus ≥18 months), and the combined CTC approach (CTC^combo-positive versus -negative) at baseline and follow-up. CI, confidence interval; HR, adjusted hazard ratio (HGSOC versus LGSOC and other types).
