Regimens with intraperitoneal cisplatin plus intravenuous cyclophosphamide and intraperitoneal carboplatin plus intravenuous cyclophosphamide are equally effective in second line intraperitoneal chemotherapy for advanced ovarian cancer

ABSTRACTPurposeWe compared response, survival and side effects of regiments with intravenous cyclophosphamide followed by intraperitoneal cisplatin versus intravenous cyclophosphamide followed by intraperitoneal carboplatin as second line treatment in one center retrospective study.Material and MethodsInclusion criteria were: relapse or recurrence of the disease after surgery and first line treatment; stage III histologicaly documented serous epithelial ovarian cancer after one or more prior regiments of chemotherapy. Recurrence were confirmed throughout restaging laparotomy or second look laparotomy. Patients from one of the groups received 90mg/m2 cisplatin on the first day and 750mg/m2 cyclophosphamide intravenously, while the second group members AUC 6 carboplatin intraperitoneally and 750mg/m2 cyclophosphamide intravenously. Four courses were administrated for each patient.ResultsOf the 49 patients in the cisplatin group the response rates were 21 (43%), 10 (20%) and 18 (37%) in the groups of pathologic complete response, pathologic partial response and progressive disease, respectively. The median survival from the initiation of intraperitoneal chemotherapy was 59 months. Of the 25 patients in the carboplatin group the response rates were 10 (40%), 4 (16%) and 11 (44%) respectively. The median survival -51 months. The differences between the groups were not statistically significant p>0.05 either in response or in toxicity.ConclusionsThe results of our research including relatively long survival from intraperotoneal chemotherapy initiation confirm that carboplatin treatment is as good as cisplatin in second line intraperitoneal chemotherapy for ovarian cancer.
