Vinorelbine, ifosfamide, and cisplatin combination as salvage chemotherapy in advanced non-small cell lung cancer

Platinum-based chemotherapy improves survival and quality of life as compared with the best supportive care alone in advanced non-small cell lung cancer. In addition, several recent studies using new drugs such as docetaxel have demonstrated that second-line chemotherapy may be of value.

We studied the efficacy of combination treatment with vinorelbine, ifosfamide, and cisplatin (NIP) as salvage chemotherapy in patients with advanced non-small cell lung cancer (NSCLC). From March 1998 to December 1999, 44 previously treated patients (etoposide/cisplatin (EP): 36, EP--> taxane/cisplatin: 8) were treated with a chemotherapy regimen consisting of vinorelbine (25 mg/m(2) i.v. on days 1, 15 and 12.5 mg/m(2) i.v. on day 8), ifosfamide (3 g/m(2) i.v. on day 1 with mesna) and cisplatin (60 mg/m(2) i.v. on day 1). The cycles were repeated every 4 weeks.

All patients were evaluable for response. The median follow-up duration was 19.1 months (range, 4.4-28.3 months). The objective response rate was 27.3% (95% CI, 14.1%-40.5%) with one complete response and 11 partial responses. The median response duration was 4.1 months (range, 1.5-13 months). The median time to progression was 2.9 months (range, 0.7-15.3 months). The main toxicity was hematologic in the 138 evaluable courses, granulocytopenia (>or=grade III) and anemia (>or=grade III) were observed in 3.6% and 0.7% of the patients, respectively. Non-hematologic toxicities were minor and easily controlled. Four episodes of febrile neutropenia were reported. There were no treatment-related deaths.

In this study, the combination of vinorelbine, ifosfamide and cisplatin showed a significant efficacy with acceptable toxicities as salvage chemotherapy in previously treated advanced NSCLC patients.
