Cisplatin-based chemotherapy combinations improve quality of life and survival in advanced nonsmall cell lung carcinoma (NSCLC). The emergence of new active drugs might translate into more effective regimens for the treatment of this disease.
The objective of this study was to determine the feasibility, response rate, and toxicity of a paclitaxel, cisplatin, and gemcitabine combination to treat metastatic NSCLC. Thirty-five consecutive chemotherapy-naive patients with Stage IV NSCLC and an Eastern Cooperative Oncology Group performance status of 0-2 were treated with a combination of paclitaxel (135 mg/m(2) given intravenously in 3 hours) on Day 1, cisplatin (120 mg/m(2) given intravenously in 6 hours) on Day 1, and gemcitabine (800 mg/m(2) given intravenously in 30 minutes) on Days 1 and 8, every 4 weeks. Although responding patients were scheduled to receive consolidation radiotherapy and 24 patients received preplanned second-line chemotherapy after disease progression, the response and toxicity rates reported refer only to the chemotherapy regimen given.
All the patients were examined for toxicity; 34 were examinable for response. An objective response was observed in 73.5% of the patients (95% confidence interval [CI], 55.6-87.1%), including 4 complete responses (11.7%). According to intention-to-treat, the overall response rate was 71.4% (95% CI, 53. 7-85.4%). After 154 courses of therapy, the median dose intensity was 131 mg/m(2) for paclitaxel (97.3%), 117 mg/m(2) for cisplatin (97.3%), and 1378 mg/m(2) for gemcitabine (86.2%). World Health Organization Grade 3-4 neutropenia and thrombocytopenia occurred in 39.9% and 11.4% of patients, respectively. There was one treatment-related death. Nonhematologic toxicities were mild. After a median follow-up of 22 months, the median progression free survival rate was 7 months, and the median survival time was 16 months.
The combination of paclitaxel, cisplatin, and gemcitabine is well tolerated and shows high activity in metastatic NSCLC. This treatment merits further comparison with other cisplatin-based regimens.
