Salvage therapy with ifosfamide and mitoxantrone in advanced ovarian cancer

To evaluate the anti-tumour activity and toxicity of ifosfamide (5 g/m2 continuous infusion) and mitoxantrone (10 mg/m2) given in combination every 3 weeks in patients with ovarian cancer resistant to at least two previous regimens which included platinum.

Objective: To evaluate the anti-tumour activity and toxicity of ifosfamide (5 g/m2 continuous infusion) and mitoxantrone (10 mg/m2) given in combination every 3 weeks in patients with ovarian cancer resistant to at least two previous regimens which included platinum. Patients and methods: Additional eligibility criteria were an ECOG performance status ≤2 and measurable disease. Of 47 patients entered in the study, 8 were defined as platinum-resistant and 39 as potentially sensitive according to Markman's criteria. Thirty-five patients had also received paclitaxel as last treatment before entering this study. Tumour response was evaluated every three cycles. Results: One complete and 11 partial responses were reported, for an overall response rate of 25% (95% CI: 14%-40%). Three of the partial responders were resistant to platinum. None of the 7 partial responders pretreated with taxol had responded to it. The overall median survival was 11 months. Neutropenia G4 was reported in 18 pati...
