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 II trial to compare the effectiveness of two combination chemotherapy regimens in treating patients who have extensive-stage small cell lung cancer.
- Evaluate the response frequency of patients with extensive stage small cell lung cancer treated with topotecan, cisplatin, and etoposide and with irinotecan, cisplatin, and etoposide.
- Evaluate the toxic effects of these regimens in these patients.
- Evaluate the duration of response and survival of patients treated with these regimens.
- Correlate the occurrence of various BRCP polymorphisms with clinical response and toxicity in patients treated with these regimens.
OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive topotecan IV over 30 minutes on days 1-3; etoposide IV over 60 minutes immediately followed by cisplatin IV over 60 minutes on days 8-10; and filgrastim (G-CSF) subcutaneously daily beginning on day 11 and continuing until blood counts recover.
- Arm II: Patients receive irinotecan IV over 90 minutes and cisplatin IV over 60 minutes on days 1 and 8 and oral etoposide twice daily on days 3 and 10.
In both arms, treatment repeats every 3 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.
Patients are followed every 3 months for 2 years and then every 6 months for 1 year.
PROJECTED ACCRUAL: A total of 60-140 patients (30-70 per treatment arm) will be accrued for this study within 7-16 months.
Allocation: Randomized, Control: Active Control, Primary Purpose: Treatment

A pharmaceutical preparation of sitagliptin phosphate and metformin hydrochloride that is used in the treatment of TYPE 2 DIABETES.
A quinazoline derivative and ANTINEOPLASTIC AGENT that functions as a PROTEIN KINASE INHIBITOR for EGFR associated tyrosine kinase. It is used in the treatment of NON-SMALL CELL LUNG CANCER.
A semisynthetic derivative of PODOPHYLLOTOXIN that exhibits antitumor activity. Etoposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent entry into the mitotic phase of cell division, and lead to cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle.
A benzamide derivative that is used as a dopamine antagonist.
Used in the form of the hydrochloride as a reagent in ANALYTICAL CHEMISTRY TECHNIQUES.
