AbstractWe report a phase II study to evaluate the survival rate, response rate and toxicity of concurrent chemoradiation therapy (CCRT) followed by consolidation chemotherapy (CT) with oral etoposide and cisplatin for patients with locally advanced inoperable non-small cell lung cancer (NSCLC). Fifty-four patients with locally advanced inoperable NSCLC who had received no prior therapy were enrolled into this trial between May 1995 and December 2000. Treatment consisted of two cycles of concurrent CT and four cycles of consolidation CT with oral etoposide (50 mg/m2) on days 1-14 during the CCRT courses and on days 1-21 during the consolidation CT courses, plus cisplatin (75 mg/m2 i.v.) on day 1 of a 28-day cycle. Conventional radiotherapy (1.8 Gy/fraction, 63 Gy over 7 weeks) was delivered from day 1 of the CT. Fifty-two patients were evaluable for response. Twelve patients (22%) achieved complete responses, and 32 patients (60%) achieved partial responses, for an overall response rate of 82% with a median duration of response of 9.1 months. Forty-three per cent developed grade 4 haematological toxicity, 11% grade 3 or 4 oesophagitis and 7% grade 3 or 4 lung toxicity. There were two treatment-related deaths, one from radiation pneumonitis and the other from sepsis. After a median follow-up duration of 50 months (range 20-85), the median overall survival time was 15.3 months (95% CI, 9.7-20.8), and the 1-, 2-, 3-, and 5 year overall survival rates were 62, 40, 30 and 16%, respectively. The duration of median progression-free survival was 12.3 months (95% CI, 7.4-17.3), and the 1-, 2-, 3-, and 5-year progression-free survival rates were 47, 40, 29 and 23%, respectively. Thus, concurrent conventional chest radiotherapy with oral etoposide plus cisplatin followed by consolidation CT led to an encouraging survival rate and prolongation of the time to progression, with moderate toxicity in patients with locally advanced inoperable NSCLC.
