BACKGROUND AND OBJECTIVE:Sequential and concurrent chemoradiotherapy were widely studied in locally advanced non-small cell lung cancer (NSCLC), but the reports of induction chemotherapy followed concurrent chemoradiotherapy are rare so far. The little side effects of paclitaxel liposme may be convenient to carry out induction chemotherapy followed concurrent chemoradiotherapy. The aim of this study is to compare the effects and side effects of TP regimen (Paclitaxel liposme and cisplatin) induction chemotherapy followed concurrent chemoradiotherapy with sequential radiotherapy on locally advanced NSCLC. METHODS:Sixty locally advanced NSCLC patients were randomly divided into group A, induction chemotherapy followed concurrent chemoradiotherapy and group B, sequential radiotherapy group. The patients in group A received 2-3 cycles of induced chemotherapy included of Paclitaxelliposme 135 mg/m²-175 mg/m², d1 and cisplatin 70 mg/m²-80 mg/m², d2, 3 weeks repeat and after 2-3 cycles followed by concurrent chemoradiotherapy. The patients in group B received chemotherapy, (as described above in group A) 4-6 cycles of chemotherapy followed one cycle of radiotherapy. The three-dimensional conformal radiotherapy at the total dose of 56 Gy-70 Gy was applied in all patients. RESULTS: The response rate in group A and group B were 80.3% and 60%, respectively (P=0.042). 1-year survival rates were 71.4% and 53.2%, respectively (P=0.18). And there were no significant difference of myelosuppression, radiation esophagitis and pulmonary fibrosis between the two groups (P=0.09, P=0.147, P=0.276, respectively). CONCLUSIONS: The recent effects of induction chemotherapy followed by concurrent chemoradiotherapy group were better than sequential radiotherapygroup on locally advanced NSCLC and there was no significant difference in side effects between the two groups.
