Paclitaxel and cisplatin as salvage treatment in patients with non-seminomatous germ cell tumour who failed to achieve a complete remission on induction chemotherapy.
The purpose of this study was to evaluate the efficacy and toxicity of paclitaxel and cisplatin combination chemotherapy as salvage treatment in patients with non-seminomatous germ cell tumour. Sixteen patients with histologically proven germ cell tumour, measurable disease and/or elevated serum tumour markers were eligible for the protocol. All patients had previously not achieved a complete remission (CR) to platinum-based induction chemotherapy and cytoreductive surgery. The treatment consisted of paclitaxel 175-225 mg/m2 as a 3-hour infusion, followed by cisplatin 100 mg/m2, repeated every 3 weeks for up to four cycles. Seven patients achieved a marker-positive partial remission (PR) by the end of the cisplatin-based induction chemotherapy; the remainder had disease progression at the start of the paclitaxel plus cisplatin treatment. One (6%) CR and 3 (19%) PRs were achieved, with an overall response rate of 25% (90% confidence interval 7-43). The duration of the CR is currently 9+ months; two PRs lasted 2 months. One patient with a PR has been lost to follow-up. During a median follow-up of 8 months (range 1-11), 12 patients died from the disease progression. The median survival for the whole group was 7 months. Toxicity was moderate, with neutropenia grade 3 occurring in 29% of patients, thrombocytopenia grade 1-3 in 29%, creatinine > 130 mmol/l in 36%, peripheral neuropathy grade 1-2 in 50%, and nausea and vomiting in 43%. Paclitaxel plus cisplatin showed modest activity, with an overall response rate of 31% in patients with poor prognosis who had not achieved a CR on induction chemotherapy.
