The combination of ifosfamide with oral etoposide appears to have significant but manageable toxicity and encouraging efficacy in platinum resistant ovarian cancer .
Ifosfamide plus oral etoposide salvage chemotherapy for platinum-resistant paclitaxel-pretreated ovarian cancer. The prognosis of platinum resistant ovarian cancer is very poor and the treatment of choice has not been clearly defined. ### Patients And Methods We conducted a phase II study with the combination of ifosfamide i.v. at 2.25 g/m2 (days 1, 2) and etoposide per os at 100 mg daily (days 1-10) every four weeks. To be eligible for the study patients had to be resistant to platinum and paclitaxel pretreated. ### results Forty-one patients entered the study. The median interval from the previous chemotherapy was 3.9 months. The median number of previous chemotherapeutic regimens was 2. Severe toxicities included neutropenia (41% of patients), leukopenia (29%) and thrombocytopenia (13%). Thirty-five patients are assessable for response. Nine patients responded (22% of the eligible, 26% of the assessable), four of them demonstrated complete response to chemotherapy (10% and 12%, respectively), while three patients demonstrated stabilization of their progressive disease. After a median follow-up of 18 months, time to progression is 3 months (range 0.9-14.4), duration of response is 9 months (2.5-11) and median survival is 13 months (2.5-37.4+). ### conclusions The combination of ifosfamide with oral etoposide appears to have significant but manageable toxicity and encouraging efficacy in platinum resistant ovarian cancer .
