Fig. 3. Kaplan-Meier curves for the OS of patients with stage IVB endometrial cancer with or without intra-abdominal residual disease after surgery. R (0): no macroscopic residual tumor; R (1): with macroscopic residual tumor. R (0) vs. R (1): HR (95% CI)=3.02 (1.53–5.94). R (0) vs. Without surgery: HR (95% CI)=3.83 (1.79–8.17).
CI, confidence interval; HR, hazard ratio; OS, overall survival.
