对甲苯磺酰胺瘤内注射结合放疗及化疗治疗裸鼠移植性肝癌的实验观察

目的 观察放疗及化疗结合对甲苯磺酰胺(PTS)瘤内局部注射对裸鼠移植性肝癌的治疗作用,为临床应用提供实验依据.方法 制作裸鼠皮下移植性肿瘤模型,将60只Balb/c(nu/nu)裸鼠随机分为6组,即PTS组、放疗组、放疗+PTS组、化疗组、化疗+PTS组和对照组,分别经皮瘤内注射PTS、局部肿瘤单纯放疗、瘤内注射PTS+局部肿瘤放疗、局部肿瘤经尾静脉注射丝裂霉素化疗、瘤内注射PTS+局部肿瘤经尾静脉注射丝裂霉素化疗、生理盐水,观察各组抑瘤率和生存期.结果 (1)放疗、化疗、PTS和放疗、化疗分别结合PTS局部肿瘤注射明显抑制肿瘤生长,而放疗、化疗结合局部肿瘤注射PTS抑制肿瘤生长又优于单纯化疗,与单纯放疗相比无统计学意义;(2)放疗、化疗、PTS和放疗、化疗分别结合PTS局部肿瘤注射裸鼠生存时间无统计学差别.结论 放疗、化疗结合局部肿瘤注射PTS治疗裸鼠移植性肝癌,疗效优于单纯放疗或单纯化疗.

Terapeutic effect of para-toluenesulfonamide on transplanted hepatocarcinoma in nude mice

Objective To study the effect of of percutaneous para-toluenesulfonamide (PTS) injection on transplanted hepatocarcinoma in nude mice. Methods Sixty nude mice with subcutaneous transplanted hepatocarcinoma were randomized into 6 groups,namely PTS,chemotherapy,radiotherapy,PTS+chemotherapy,PTS+radiotherapy and control groups. PTS were injected into the tumor in the nude mouse models as indicated,and the tumor growth rate and survival time of the mice were recorded. Results All the treatments resulted in effe...
