摘要 目的探讨同步放化疗治疗局部晚期表皮生长因子受体(epidermal growth factor receptor,EGFR)野生型非小细胞肺癌(non-small cell lung cancer,NSCLC)合并慢性阻塞性肺病(chronic obstructive pulmonary disease,COPD)和肺不张患者的近期疗效及毒副反应。方法对42例局部晚期EGFR野生型NSCLC合并COPD和肺不张的患者给予低分割大剂量调强放射治疗,Dt:5Gy/次,隔日一次,3次/周,总剂量达到50~60Gy/10~12次,同步EP方案依托泊苷50 mg/m^2d1~5,顺铂d1~5(总量70 mg/m^2)化疗,每四周为一周期,共化疗两周期后评估患者疗效。结果治疗结束后复查患者胸部CT评估患者肺部原发肿块及纵膈阳性淋巴结退缩情况完全缓解(complete remission,CR)6例(14.3%),部分缓解(partial remission,PR)31例(73.8%),稳定(stable disease,SD)5例(11.9%),进展(progressive disease,PD)0例;毒副反应情况:毒性反应主要表现为放射性肺炎,其中0级16例(38.1%),Ⅰ~Ⅱ级21例(50%),Ⅲ级5例(12%)。结论对于局部晚期EGFR野生型NSCLC合并COPD和肺不张的患者低分割调强放射治疗同步EP方案化疗安全有效,毒副反应可以耐受。 Objective To explore the recent therapeutic effect and adverse reactions of chemoradiation for epidermal growth factor receptor( EGFR) wild-type LA-non-small cell lung cancer( NSCLC) patients with chronic obstructive pulmonary disease( COPD) and atelectasis. Methods 42 patients receive hypofractionation Intensity-modulated radiotherapy, 5 Gy/fraction, three times/week, total dose 50-60Gy/10-12 fractions,Concurrent chemotherapy with etoposide 50 mg/m^2 on days1 to 5 and cisplatin on days 1 to 5( total 70 mg/m^2)every 4 weeks for two cycles. Result After treatment,42 patients complete remission( CR) 6 cases( 14.3%),partial remission( PR) 31 cases( 73.8%),stable disease( SD) 5 cases( 11. 9%),progressive disease( PD) 0case; Toxic effects mainly for radioactive pneumonia,of which the 0 level 16 cases( 38.1%),Ⅰ-Ⅱ level 21cases( 50%),Ⅲ level 5 cases( 12%). Conclusion hypofractionation Intensity-modulated radiotherapy Concurrent EP chemotherapy is effective and well-tolerated for EGFR wild-type LA-NSCLC patients with COPD and atelectasis.
