膀胱肿瘤化疗药物敏感性试验对个体化治疗的指导作用

目的探讨药物敏感性试验对膀胱肿瘤灌注化疗药物选择的指导价值。方法将82例非肌层浸润膀胱尿路上皮癌患者非随机分为两组，药敏组34例行膀胱肿瘤细胞原代培养＋药物敏感性试验（MTT法），并根据药物敏感结果选择化疗药物行膀胱灌注，对照组48例按经验选择药物行灌注化疗。结果药物敏感试验结果显示对表柔比星敏感19例，敏感率59．4％；吡柔比星16例，敏感率47．6％；丝裂霉素20例，敏感率41．2％；羟基喜树碱30例，敏感率88．2％；平均随访22．3个月，药敏组复发率为11．7％（4／34），对照组复发率为31．2％（15／48），两组相比差异有统计学意义（P〈0．05）。结论膀胱肿瘤药物敏感性试验可以有效指导膀胱灌注用药，降低非肌层浸润膀胱尿路上皮癌远期复发率。

Direction effect of drug sensitivity test of bladder cancer and the individual choice of chemotherapy

Objective To evaluate the direction effect of drug sensitivity test of bladder cancer and the individual choice of chemotherapy. Methods MTT was used to determine chemotherapy and all 34 patients were followed up for 6-43 months. 48 cases were based on the experience of doctors control. Results The sensitive cases were ADM19, THP16, MMC20, OPT30. The sensitive rate was epi-ADM 59.4 %, THP 47.6 %, MMC 41.2 %, OPT 88.2 %. The recurrence rate was 8.82 % in drug sensitivity group, 31.2 % in control group, the result of experiment group was perfect to the control.group. Conclusion The difference of the individual chemotherapy sensitivity is significant. The drug sensitivity test can improve the therapeutic effect of bladder cancer.
