Background: The aim of this study is to determine feasibility and efficacy of the combination regimen oxaliplatin and paclitaxel in patients with cisplatin (CDDP)-refractory germ-cell tumors (GCT).
Patients and methods: Patients with either a cisplatin absolute-refractory GCT defined as progressive disease (PD) during or within 1 month of CDDP administration or with a poor prognosis relapse, defined as PD between the second and the sixth month after CDDP administration, were treated with a combination of oxaliplatin (130 mg/m2) and paclitaxel (175 mg/m2) administered every 21 days. Primary end point was efficacy.
Results: Twenty-seven patients were included. Patients were pretreated with a median of two lines of cisplatin-based chemotherapy (range 1–5). Sixteen patients were absolute refractory. Five patients had relapsed after high-dose chemotherapy plus stem-cell support. There were no complete responses but there was one marker-positive partial response and nine disease stabilization (34, 6%). After a median follow-up of 65 months, two patients are disease-free survivors. Main toxicity was leucocytopenia grade 3/4 in 30% of the patients.
Conclusion: Combination chemotherapy with oxaliplatin and paclitaxel is feasible with acceptable toxicity and may be effective if combined with additional treatment in patients with CDDP-refractory GCT.
