About
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 extensive-stage small cell lung cancer.
PURPOSE: Randomized phase III trial to compare different chemotherapy regimens in treating patients who have extensive-stage small cell lung cancer.
Full description
OBJECTIVES:
- Compare the overall survival of patients with chemotherapy-naive extensive stage small cell lung cancer treated with cisplatin and oral topotecan vs cisplatin and etoposide.
- Compare the response rates, response duration, and time to progression in patients treated with these regimens.
- Compare the tolerability of these regimens in these patients.
- Compare the patient-perceived disease status and well being in patients treated with these regimens.
OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to gender, ECOG performance status (0 vs 1 vs 2), lactate dehydrogenase (less than 1.5 times upper limit of normal (ULN) vs 1.5 times ULN or greater), and country. Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive oral topotecan once daily on days 1-5 and cisplatin IV on day 5.
- Arm II: Patients receive cisplatin IV on day 1 and etoposide IV over at least 30 minutes on days 1-3.
Treatment in both arms repeats every 21 days for at least 4 courses in the absence of disease progression or unacceptable toxicity.
Quality of life is assessed at baseline, prior to each course, at 4 weeks after study, and then every 4 weeks for 16 weeks.
Patients are followed at 4 weeks, every 4 weeks for 16 weeks, and then every 3 months thereafter.
PROJECTED ACCRUAL: Approximately 760 patients (380 per treatment arm) will be accrued for this study within 18 months.
