Effect of different chemotherapy regimens for concurrent chemoradiotherapy on locally advanced non-small cell lung cancer / 中华肿瘤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To retrospectively analyze the effects of different chemotherapy regimens for concurrent chemoradiation on locally advanced non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>The data from 106 patients diagnosed as locally advanced NSCLC (IIIa 29, IIIb 77), who received various chemotherapy regimens for concurrent chemoradiotherapy, were retrospectively analyzed. Paclitaxel-based chemotherapy regimen was administered in 55 patients, topotecan regimen in 21 patients, PE (cisplatin and etopside) regimen in 26 patients, and other regimens in the remaining 4 patients. The effect of different chemotherapy regimens on overall survival and toxicity was analyzed.</p><p><b>RESULTS</b>The median survival time was 18.6 months, and the overall 1- and 3-year survival rates were 72.2% and 27.5%, respectively. The median survival time of 102 patients treated with paclitaxel-containing, topotecan-containing or PE regimens was 16.3, 27.3 and 29.1 months, respectively. The overall survival times of topotecan and PE groups were superior to that of paclitaxol-based group, but not significantly different (P = 0.32). Both univariate and multivariate analysis showed that paclitaxol-based chemotherapy regimen was significantly associated with a poorer survival (P < 0.05). N stage was another significant prognostic factor determined by COX multivariate regression model. Compared with the other regimens (10.6%), paclitaxel-based regimen (27.3%) had more acute radiation pneumonitis (grade >or= 2, P = 0.03), but no significant differences were observed in blood toxicity and esophagitis.</p><p><b>CONCLUSION</b>There is a correlation between different chemotherapy regimens for concurrent chemoradiotherapy and the overall survival and acute radiation pneumonitis in patients with locally advanced NSCLC.</p>
