Abstract Forty-one patients with marginally resectable stage III M0 non-small cell lung cancer (NSCLC) were entered into a study evaluating neoadjuvant cyclophosphamide, adriamycin, and cisplatin chemotherapy (CAP) followed by radiotherapy and subsequent resection. Postoperative radiotherapy and additional CAP were also administered. The objective disease regression rate prior to surgery was 72\% (2 complete, 12 partial, and 7 minimal responses). Thoracotomy was carried out in 37 patients (90\%), with resection of all gross disease in 36 patients (97\%). Relapse occurred in 22 (61\%) of the resected patients, involving chest only (four patients), chest and extra thoracic (nine patients), and extra thoracic only (nine patients). Subsequent CNS relapse developed in 9 (25\%) of 36 postop patients in association with other sites of relapse (five patients) or as a solitary location (four patients). Only one of seven patients receiving prophylactic cranial irradiation (PCI) developed CNS relapse compared with 7 (26\%) of 27 patients not receiving PCI. The median long-term follow-up for 14 living patients is 53+ months, with a rang of 38+ to 71+ months. Median survival for all patients is 32 months, with 1-year survival being 75\%. The survival curve shows a plateau of 31\% from 3 to 5+ years. Using a log rank test, no prognostic subgroups could be identified that significantly affected response rate, disease-free survival, or overall survival. While neoadjuvant CAP followed by radiotherapy appears to improve survival, more effective chemotherapy along with randomized studies are needed to determine the role of initial chemotherapy in marginally resectable NSCLC.
