OBJECTIVES:
Primary
* To evaluate the efficacy of induction chemotherapy comprising irinotecan hydrochloride and cisplatin in patients with locally advanced, unresectable stage III non-small cell lung cancer.
* To evaluate the feasibility of radiotherapy administered concurrently with etoposide and cisplatin chemotherapy after induction chemotherapy in these patients.
Secondary
* To evaluate the toxicity of induction chemotherapy comprising irinotecan hydrochloride and cisplatin in these patients.
* To assess whether this induction chemotherapy regimen will improve patient survival when compared with outcomes from the predecessor study, SWOG-9019.
OUTLINE: Patients receive dose-dense induction chemotherapy comprising irinotecan hydrochloride IV and cisplatin IV on days 1 and 8. Treatment repeats every 21 days for up to 2 courses.
After completion of induction chemotherapy, patients undergo radiotherapy five days a week for approximately 7 weeks. Patients receive concurrent chemotherapy comprising cisplatin IV on days 1, 8, 29, and 36 and etoposide IV on days 1-5 and 29-33.
After completion of study therapy, patients are followed at 6 weeks.
