Abstract:
BACKGROUND:The effect of adjuvant chemotherapy after resection of nonsmall cell lung cancer (NSCLC) remains an unresolved question. METHODS:From October, 1982, to November, 1986, 267 patients with resected NSCLC were included in a randomized trial. The adjuvant allocated treatments were either postoperative radiotherapy, 60 Gy in 6 weeks (radiotherapy group = 129 patients), or three courses of postoperative COPAC (cyclophosphamide, doxorubicin, cisplatin, vincristine, lomustine) chemotherapy followed by a similar radiotherapy schedule (chemotherapy/radiotherapy group = 138 patients). RESULTS:The sex ratio (M:F) was 19/1; mean age was 57 +/- 9 years. According to postoperative staging, 8 patients were Stage I, 70 were Stage II, and 189 were Stage III. The histologic type was squamous cell carcinoma in 175 patients, adenocarcinoma in 57, and large cell carcinoma in 35. The minimum follow-up was 6 years. Four patients were lost to follow-up. Death was recorded in 233 patients. No significant difference was observed in terms of disease free interval (P = 0.47, log-rank test), or overall survival (P = 0.68, log-rank test). With respect to the first site of relapse, distant metastasis occurred more frequently in the radiotherapy group (P = 0.09, log-rank test) whereas local relapse occurred similarly in both groups (P = 0.27). An interaction was observed between lymph node involvement and treatment in terms of overall survival. CONCLUSIONS:The COPAC chemotherapy as postoperative treatment failed to improve overall survival in patients with resected NSCLC receiving postoperative radiotherapy but decreased the pattern of metastatic progression, mainly in the N2 patients.
