Abstract:
Objective:To study the efficacy of stereotactic radiotherapy (SRT) combined with gemcitabine plus cisplatin (GP)-based chemotherapy on local recurrent non-small-cell lung cancer (NSCLC) after radiotherapy. Methods:Thirty-eight patients with local recurrent NSCLC were treated with SRT(3.00-4.85 Gy per fraction, five times every week, totally 8-12 fractions, total course of 2-3 weeks). Before SRT the patients were given two cycles of GP-based chemotherapy (gemcitabine 1 000 mg/m~2 d 1 and d 8;cisplatin 30 mg/m~2 d 1-3) and at the end of SRT they were given 4 cycles of GP-based chemotherapy. Results:Of the 38 patients,7 patients had complete response, and 23 patients achieved partial response. The overall immediate response rate was 78.95% (30/38). The 6-month and 12-month total survival rates were 71.05% and 10.53%,respectively. The median survival time was 7.8 months. Conclusion:SRT combined with GP-based chemotherapy had better short-term efficacy and the patients were tolerable. No severe short-term radiation-induced injury was observed. The long-term radiation-induced injury and long-term efficacy need further investigation.
