Paclitaxel and Carboplatin Chemotherapy Compared With Standard Chemotherapy in Treating Patients With Stage III or Stage IV Non-small Cell Lung Cancer That Cannot Be Removed During Surgery

A Randomized Phase III Comparative Study of Paclitaxel With Carboplatin Versus Mitomycin, Ifosfamide, Cisplatin (MIC) Chemotherapy in Inoperable Advanced Stage Non-Small Cell Lung Cancer

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether paclitaxel and carboplatin is more effective than standard chemotherapy for advanced non-small cell lung cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of paclitaxel and carboplatin chemotherapy with that of standard chemotherapy in treating patients who have stage III or stage IV non-small cell lung cancer that cannot be removed during surgery.

OBJECTIVES:

• Compare the one and two year survival of patients with inoperable advanced non-small cell lung cancer treated with paclitaxel and cisplatin versus standard platinum therapy.
• Compare the toxic effects of these two regimens in this patient population.
• Compare the performance status, tumor response, and quality of life in these patients after these treatment regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to center, stage of disease (IIIA vs IIIB vs IV), or performance status (ECOG O vs 1 vs 2 vs 3).

Patients are randomized to one of two treatment arms:

• Arm I: Patients receive paclitaxel IV over 3 hours, followed by carboplatin IV over 30 minutes on day 1.
• Arm II: Patients receive mitomycin IV, ifosfamide IV over 3 hours, and cisplatin IV over 1 hour on day 1 OR mitomycin IV, vinblastine IV, and cisplatin IV over 4 hours on day 1.

Treatment continues every 3 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.

Quality of life is assessed before each treatment course.

Patients are followed for survival.

PROJECTED ACCRUAL: Approximately 300 patients (150 per treatment arm) will be accrued for this study.
