Background
The purpose of this study was to observe the role of secondary cytoreductive surgery in platinum-resistant recurrent ovarian cancer (OC) patients.
Methods
We collected data of patients affected by recurrent OC treated between 1995 and 2013. Inclusion criteria were: invasive epithelial OC histologically documented, cytoreductive surgery and platinum-based chemotherapy at first-line treat
ment with evidence of complete response to treatment, disease-free interval <6 months, and no concomitant neoplasia. Patients considered susceptible of cytoreductive surgery (group A) were compared with a historical series of patients with similar characteristics but not eligible for surgery (group B).
Results
Of 122 platinum-resistant patients, 18 met the inclusion criteria for the study and were enrolled. They were compared with a historical series of 18 patients not surgically treated with analogous clinical and pathological features. The most frequent sites of relapse included pelvic and aortic lymph nodes (39 %), peritoneum (33 %), bowel (28 %), and pelvis (22 %). A low rate of intraoperative and postoperative complications was reported. No deaths were recorded. Overall survival was significantly longer in cytoreductive group when compared with the control group (P = 0.035). Median overall survival was 44 months. Estimated 5-year overall survival rates were 57 versus 23.5 % for groups A and B, respectively.
Conclusions
Surgery could represent a useful adjunct to chemotherapy in the management of platinum-resistant recurrent OC patients, carefully selected, in highly selected centers. Larger prospective trials are needed to further confirm our experience.
