Abstract
Objective
To identify clinical prognostic factor improving survival of recurrent epithelial ovarian cancer (EOC) patients treated with secondary cytoreductive surgery (SCS).
Methods
The indications of SCS were as follows; 1) complete response (CR) after primary cytoreductive surgery and adjuvant chemotherapy, 2) disease-free survival (DFS) (≥6 months). Clinical data of 17 patients including age, DFS, peritoneal seeding identified during SCS, the number of recurrent tumors (≥1 cm), serum CA-125 levels and maximal diameter of residual tumor after SCS were reviewed retrospectively between January 1990 and March 2007. Survival analyses were performed using Kaplan-Meier method with log-rank test and univariate Cox's regression analysis.
Results
Mean age of them was 51.7 years. No peritoneal seeding identified during SCS was a prognostic factor improving progression-free survival after SCS (PFS-SCS) (30 vs. 6 months, p<.01 hazard ratio 0.099, 95% confidence interval 0.011-0.929, p=.043). Furthermore, serum CA-125 level (≤37 U/ml) after SCS was a significant prognostic factors improving overall survival (51 vs. 19 months, p=.033; hazard ratio 0.212, 95% confidence interval 0.045-0.983, p=.045).
