- Arm I: Patients receive induction with cisplatin IV over 1 hour on days 1 and 8 and etoposide IV over 1 hour on days 1-5. Treatment continues every 4 weeks for 2 courses in the absence of disease progression or unacceptable toxicity. Beginning within 24 hours of the first dose of chemotherapy, patients undergo induction radiotherapy 5 days a week for 5 weeks in the absence of disease progression or unacceptable toxicity. Patients without local progression or distant metastases at 2-4 weeks after completion of course 2 undergo resection approximately 3-5 weeks after completion of course 2. All visible, accessible bronchopulmonary, hilar, and mediastinal lymph nodes are excised. The choice of surgical procedure (thoracotomy, lobectomy, or pneumonectomy with en bloc resection of tumor extending into the parietal pleura, chest wall, pericardium, or diaphragm) is at the discretion of the surgeon. Patients who undergo resection receive 2 additional courses of chemotherapy alone beginning 4-6 weeks postoperatively. Patients with unresectable disease or who are medically unfit for or refuse resection receive 2 additional courses of chemotherapy alone beginning immediately after completion of course 2.
