Cochrane Collaboration: Interval debulking surgery for advanced epithelial

* Rates of toxic reactions to chemotherapy were similar in both arms (RR = 1.3, 95%CI: 0.4 to 3.6), but little information is available for other adverse events.
* Only one trial reported quality of life (QOL), which was generally similar in both treatment arms.
* No conclusive evidence was found to determine whether IDS between cycles of chemotherapy would improve or decrease the survival rates of women with advanced ovarian cancer, compared with conventional treatment of primary surgery followed by adjuvant chemotherapy. IDS appeared to yield benefit only in the patients whose primary surgery was not performed by gynecologic oncologists or was less extensive.
