Secondary cytoreductive surgery for recurrent epithelial ovarian carcinoma: Proposal for patients selection

Abstract

The value of secondary cytoreductive surgery (SCS) for recurrent ovarian cancer is still controversial. The aim of this study was to clarify candidates for SCS. Between January 1987 and September 2000, we performed SCS in 44 patients with recurrent ovarian cancer, according to our selection criteria, disease-free interval (DFI) > 6 months, performance status < 3, no apparent multiple diseases, age < 75 years and no progressive disease during preoperative chemotherapy, if undertaken. The variables were investigated by univariate and multivariate analyses. Of 44 patients, 26 (59.1%) achieved complete removal of all visible tumours at SCS. Secondary cytoreductive surgery outcome, complete or incomplete resection, was significantly related to overall survival (P = 0.0019). As for variables determined before SCS, DFI > 12 months, no liver metastasis, solitary tumour and tumour size < 6 cm were independently associated with favourable overall survival after recurrence in the multivariate analysis. Patients with three or all four variables (n = 31) had significantly better survival compared with the other patients (n = 13) (47 vs 20 months in median survival, P < 0.0001). In these patients, fairly good median survival (40 months) was obtained even in patients with incomplete resection. Secondary cytoreductive surgery had a large impact on survival of patients with recurrent ovarian cancer when they had three or all of the above-mentioned four factors at recurrence. These patients should be considered as ideal candidates for SCS. © 2005 Cancer Research UK.
