Daily times four vinorelbine plus cisplatin in advanced non-small-cell lung cancer: A phase II trial of a novel schedule

Purpose: To evaluate the efficacy of a novel multiday schedule of vinorelbine and cisplatin in patients with advanced NSCLC. Patients and methods: Thirty patients were enrolled, includ-ing 27 patients with stage IV disease, and 11 patients with performance status of 2. They received a maximum of four chemotherapy cycles with cisplatin 20 mg/m2/day and vinorel-bine 15 mg/m2/day intravenously (i.v.) for four consecutive days, every three weeks, with prophylactic filgrastim. Results: Sixteen patients responded (53%, 95 % confidence interval (95 % CI): 34%-72%), including two complete and fourteen partial confirmed responses. Median survival for all patients was 8.1 months, with actuarial one-year and two-year survival rates of 40 % and 15%. Despite prophylactic filgrastim, the delivered vinorelbine dose intensity of 16.8 mg/m2/week caused febrile neutropenia in 48 % of patients (16 % of cycles), resulting in one treatment-related death. Common nonhema-tologic toxicities included delayed emesis, asthenia, and consti-pation. Conclusions: This multiday vinorelbine-cisplatin schedule is highly active against advanced NSCLC but results in fre-quent neutropenic complications. The myelotoxicity and anti-tumor efficacy of vinorelbine in NSCLC patients may be schedule-dependent
