尿肝细胞生长因子和核基质蛋白22含量与膀胱尿路上皮癌分期和分级的关系

 摘要] 目的 探讨膀胱癌患者尿中肝细胞生长因子（HGF）和核基质蛋白22（NMP22）表达水平与膀胱癌分期和分级的关系。方法 膀胱移行细胞癌（TCC）接受保留膀胱手术的患者48例，其中19例灌注卡介苗（BCG）联合白介素2（IL-2）；29例灌注吡柔比星（THP）。采用酶联免疫吸附法（ELISA）分别检测灌注前、灌注后6月尿中HGF和NMP22的含量。结果 术后12个月复发率12.5%。灌注前尿HGF水平与肿瘤的分级、分期呈正相关（p＜0.05），NMP22与肿瘤的分级呈正相关。HGF、NMP22和尿细胞学对膀胱癌术后复发的敏感性分别为100% ,83.3%和66.7%；特异性分别为62%, 57.1%和97.6%。结论 HGF和NMP22均为膀胱癌患者尿中良好肿瘤标志物，与肿瘤的分期和分级密切相关，结合尿细胞学检测可以作为膀胱癌早期筛查和诊断的有效指标。

Relationship between content of hepatocyte growth factor and nuclear matrix protein 22 in urine and the stage and grade of bladder uroepithelium carcinoma

Objective To evaluate the relationship of the hepatocyte growth factor (HGF) and the nuclear matrix protein 22 (NMP22) in urine and the stage and grade of bladder uroepithelium carcinoma.Methods A total of 48 post-operative patients (males 39, females 9) with bladder cancer enrolled in this study were perfused with THP. The voided urine of all the patients before and 6 months after perfusion were recovered selectively. HGF and NMP22 ELISA kits were used to detect bladder cancer. Results The recurrence rate was 12.5 %. The HGF level had positive correlation with the stage and grade of bladder uroepithelium carcinoma (P ＜0.05). The NMP22 level had positive correlation with the grade of bladder cancer. The sensitivity and specificity of HGF, NMP22 and cytology were 100 % (6/6), 83.3 % (5/6), 66.7 %(4/6) and 61.9 % (26/42), 57.1% (24/42), 97.6 % (41/42), respectively. Conclusion The HGF and NMP22 are both valuable tumor markers in the urine of bladder uroepithelium carcinoma. They have intimate relation with the stage and grade of bladder uroepithelium carcinoma. Hence combined with cytology, they could be selected as the significance level of early screening and diagnosing.
