Sequential chemoradiotherapy compared with concurrent chemoradiotherapy in locally advanced non-small cell lung cancer: our experience.

From November 2005 to October 2008, 93 patients were enrolled. Eight patients were not eligible, seven had stage IV and one had pleural effusion. All these were initially considered to have stage IIIB disease. The median survival was 13 months for the patients in the sequential group and 22 months in the concurrent treatment group. The difference was statistically significant (log-rank test p = 0.001). The disease-free survival was 9 months in the sequential group and 17 months in the concurrent treatment group. The difference was statistically significant (log-rank test p = 0.001) The 1and 2-year survival rates were 73.6% and 39.7% in the concurrent group and 54.9% and 13.7% in the sequential group, respectively (log-rank test, p = 0.0011). Treatment-related toxicities were assessed according the RTOG/EORTC criteria. Acute esophagitis and incidence of neutropenia were higher with the concurrent than with the sequential treatment. Grade 3 esophagitis was characteristic only of concurrent treatment and it was a reason for radiotherapy interruption, but no longer than 7 days. Secondary anaemia was more frequent in the sequential treatment group. 198 Crvenkova S., Krstevska V. Contributions, Sec. Biol. Med. Sci., XXX/2 (2009), 197–207 The statistical significant differences in survival sugest that concurrent chemotherapy and conformal three-dimensional radiotherapy is the optimal strategy for patients with locally advanced NSCLC.
