Results: Of 59 superficial bladder cancer samples, sensitivity tests were successfully performed in 45 samples, and the others failed, the successful rate was 76.3%.Diversity of inhibiting rates of antitumor drugs was observed in samples from different individuals. Except MTX in stage of G1 and G3, no correlation has been found between the phenotype of sensitivity assay and the pathological grade and stage. Sensitivity and mean inhibiting rates of antitumor drugs in the primary group were notedly higher than that in the recurrent group.The combination of two therapy agents, which have different mechanisms or different cell-cycle targets, showed significantly more sensitivity and higer mean inhibiting rates than single one in superficial bladder cancer in different individuals.

结果：14例失败，45例获得成功，总体可评价率为76.3％，不同抗癌药物对不同个体膀胱癌的抑制率存在明显差异；除MTX对膀胱癌G1和G3级平均抑制率差异有统计学意义外，其它抗癌药物对不同个体膀胱癌细胞的平均抑制率与膀胱癌的病理分级、分期均无关；抗癌药物对初发膀胱癌的敏感率和平均抑制率均高于复发膀胱癌；两种不同作用机制的抗癌药物联合应用对不同个体膀胱癌细胞的敏感率和平均抑制率均高于单一药物，二者敏感率和平均抑制率差异有统计学意义。
