Abstract

Objective: The objective of this study was to identify the prognostic factors of secondary cytoreductive surgery on survival in patients with recurrent epithelial ovarian cancer.
Methods: The medical records of all patients who underwent secondary cytoreductive surgery between May 2001 and October 2007 at the National Cancer Center, Korea were reviewed. Univariate and multivariate analyses were executed to evaluate the potential variables for overall survival.
Results: In total, 54 patients met the inclusion criteria. Optimal cytoreduction to <0.5 cm residual disease was achieved in 87% of patients who had received secondary cytoreductive surgery. Univariate analysis revealed that site of recurrence (median survival, 53 months for the largest tumors in the pelvis vs. 24 months for the largest tumors except for the pelvis; p=0.007), progression free survival (PFS) (median survival, 43 months for PFS≥12 months vs. 24 months for PFS<12 months; p=0.036), and number of recurrence sites (median survival, 49 months for single recurred tumor vs 29 months for multiple recurred tumors; p=0.036) were significantly associated with overall survival. On multivariate analysis, prognostic factors that correlated with improved survival were site of recurrence (p=0.013), and PFS (p=0.043).
Conclusion: In the author’s analysis, a significant survival benefit was identified for the recurred largest tumors within the pelvis and PFS≥12 months. Secondary cytoreductive surgery should be offered in selected patients and large prospective studies are needed to define the selection criteria for secondary cytoreductive surgery.
