BACKGROUND: In an effort to confirm the efficacy of mitomycin Cagainst metastatic squamous cell lung carcinoma and to compare the efficacy of single-agent therapy with a combination containing cisplatin, the authors conducted a randomized Phase III trial of mitomycin C alone versus mitomycin C, vinblastine, and cisplatin (MVP). METHODS: All patients had advanced squamous cell lung carcinoma, and survival was the primary end point. There were 133 eligible patients who received eithermitomycin C alone (n = 64) or MVP (n = 69). The two groups were similar with respect to performance score, disease status, age, sex, and stage. RESULTS: The major objective response rates were 30% (95% confidence interval [CI], 18-41%) and 43% (95% CI, 32-55%) for mitomycin C alone and MVP, respectively (P = 0.1). The median time to progression was 83 days for mitomycin C alone, compared with 119 days for MVP (P = 0.026). The median survival time was 114 days for mitomycin C and 163 days for MVP (P = 0.09). The 1-year survival rates were equivalent. Myelosuppression was the major toxicity, and there were significantly greater leukocyte nadirs with MVP therapy (P < 0.001). CONCLUSION:Mitomycin C has antitumor activity against squamous cell lung carcinoma when used alone or in combination with MVP. The regimen containing cisplatin had marginally increased activity that did not translate into a clinically significant survival advantage.
