Surgery in platinum-resistant recurrent epithelial ovarian carcinoma

Figure 3 Kaplan-Meier survival curves for subgroup analysis of overall survival. The absence of residual lesions after cytoreductive surgery (P = 0.021) and postoperative chemotherapy (P < 0.001) were associated with improved overall survival. A: Age (P = 0.405); B: Eastern collaborative oncology group score (P = 0.505); C: Pathological type (P = 0.079); D: Tumor differentiation (P = 0.826); E: Absence of residual lesions after cytoreductive surgery (P = 0.021); F: Postoperative chemotherapy (P < 0.001); G: the number of chemotherapy lines (P = 0.296); H: The number of previous surgeries (P = 0.230); I: Targeted drugs (P = 0.249). ECOG: Eastern collaborative oncology group.
