Thirty-nine previously untreated small cell lung cancer patients received cyclophosphamide (CTX) + adriamycin (ADM) + vincristine (VCR) (CAV). The doses initially used were CTX 1,000 mg/body day 1, ADM 50 mg/body day, VCR 1 mg/body day, 8, 15 or 2 mg/body day(group A). Later, CTX 1,000 mg/m2 day, ADM 60 mg/m2 day, VCR 1.4 mg/m2 day were used. All patients had PS 0-3, 24 had limited disease (LD) and 15, extensive disease (ED). The overall response rate and the complete response (CR) rates were 63% (15/24) and 21% (5/24) for LD, and 21% (3/14) and 0% (0/14) for ED, respectively. The median response durations were 22 weeks for LD and 33 weeks for ED. The median CR duration in LD patients was 23 weeks. Twelve LD and 1 ED patient received thoracic radiotherapy (RT) optionally after 2-4 courses of CAV therapy. Eventually, 8 patients achieved CR. The median survival for LD, ED and all cases were 43 weeks, 37 weeks and 41 weeks, respectively. The 1, 2 and 3-year survival rates were 42, 25 and 21% for LD, and 40, 7 and 0% for ED. Three patients were long-term disease-free survivors (greater than 3 years), and these had LD and received RT. There were 3 chemotherapy-related deaths (2 patients with leukopenia + infection, 1 patient with drug-induced pneumonitis). The survival results of CAV therapy in our hospital were comparable with the recent results of chemotherapies available against small cell lung cancer.
