摘要 目的:探讨中晚期宫颈癌同步放化疗的耐受性和毒副反应。方法:2004年2005年我院开展了中晚期宫颈癌同步放化疗治疗患者54例,组织学类型为鳞癌81.48%(44/54),腺癌18.51%(10/54),Ⅱb期34例,Ⅲ期18例,Ⅳ期2例。全部病例采用体外照射和腔内近距离照射的联合放疗方案,同步应用DF化疗方案。体外照射采用6MV-X线,前后野对穿照射,常规分割每周5次,每次2Gy,外照射全盆腔剂量24Gy^30Gy/2W^3W,盆腔野挡铅4×10 cm^17 cm,加腔内近距离治疗。腔内近距离治疗每次A点剂量5Gy^6Gy,腔内照射当日不作体外照射,共5次~7次,腔内照射A点总量25Gy^42Gy。体外和腔内照射A点总量为70Gy^82Gy,B点总剂量50Gy^70Gy,总疗程6周~8周。与放化疗开始之日常规应用升白胺3片,3次/天,至疗程结束。结果:达CR者49/54(90.74%),PR者5/54(9.25%)。放疗结束宫颈刮片阴性52/54(96.29%)。本组病例治疗后均满2年,2年总生存率77.78%。本组宫颈癌患者同步放化疗副反应主要为肠道反应、泌尿系统反应、血液学毒性。急性放射性直肠反应全组发生率为46.30%(25/54),其中18例(72%)为轻度,7例(24%)为中度,全组病例无直肠阴道瘘发生。血液学毒性主要表现为白细胞下降,RTO G1级9例(16.67%),RTO G2级5例(9.25%),无3级以上毒性反应。结论:中晚期宫颈癌同步放化疗具有较好的临床耐受性,两年生存率达77.78%。通过改进外照射方式(如IMRT),降低单次腔内治疗剂量(小于6Gy),将会减轻肠道副反应。
