Randomized Study With New Combination Chemotherapies in Advanced Non-Small Cell Lung Cancer
Randomized Study With New Combination Chemotherapies in Advanced 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. Combining more than one drug may kill more tumor cells. It is not yet known which combination chemotherapy regimen is more effective in treating advanced non-small cell lung cancer.
PURPOSE: Randomized phase III trial to compare the effectiveness of three different combination chemotherapy regimens in treating patients who have advanced non-small cell lung cancer.
OBJECTIVES: I. Compare the overall survival between paclitaxel/cisplatin (arm I), gemcitabine/cisplatin (arm II), and paclitaxel/gemcitabine (arm III) in patients with advanced non-small cell lung cancer. II. Determine the response rate, duration of response, progression-free survival, toxicity, and quality of life of these patients randomized in these three treatment arms.
OUTLINE: This is randomized, multicenter study. Patients are stratified according to performance status (0-1 vs 2) and stage of disease (locally advanced vs metastatic). Patients are randomized to receive paclitaxel IV over 3 hours on day 1 followed by cisplatin IV on day 1 every 3 weeks (arm I), gemcitabine IV over 30-60 minutes on days 1 and 8 and cisplatin IV on day 1 every 3 weeks (arm II), or paclitaxel IV over 3 hours on day 1 followed by gemcitabine IV over 30-60 minutes on days 1 and 8 every 3 weeks (arm III). Patients receive at least 2 courses of treatment. In the absence of unacceptable toxicity and disease progression, patients may receive up to 6 courses of treatment. Quality of life is assessed before, during, and at the end of treatment, then every 6 weeks until disease progression, and then every 3 months until death. Patients are followed every 6 weeks until disease progression, then every 3 months until death.
PROJECTED ACCRUAL: A total of 450 patients (150 patients per arm) will be accrued into this study over 36 months.
DISEASE CHARACTERISTICS: Histologically confirmed advanced non-small cell lung cancer that is progressive within 2 months prior to study entry Stage IIIB due to malignant pleural effusion or supraclavicular lymph node involvement only Stage IV At least 1 bidimensionally or unidimensionally measurable target lesion Brain metastases or leptomeningeal disease that have been treated with radiotherapy, is stable without medications (e.g., steroids), and asymptomatic are allowed
