目的

探讨核苷酸切除修复交错互补基因1(ERCC1)和核糖核苷酸还原酶M1(RRM1)基因在膀胱肿瘤的表达情况及其与非肌层浸润性膀胱癌肿瘤经膀胱灌注吉西他滨的疗效的关系。

方法

回顾性总结2014年07月至2018年07入我院经病理证实膀胱癌患者共86例,其中非浸润型50例,浸润型36例,同期选择30例膀胱良性肿瘤;采用实时荧光定量PCR检测膀胱癌组织ERCC1和RRM1 mRNAs定量表达水平。随访时间15~63个月,中位时间41.5个月,记录非浸润型患者的无进展生存时间(PFS)、中位生存期、总复发率和生存率,分析ERCC1和RRM1基因表达与灌注效果的相关性。

结果

与膀胱良性肿瘤组患者比较,膀胱癌患者肿瘤组织RRM1呈高表达,ERCC1呈低表达,并且浸润型患者RRM1明显高于非浸润型,ERCC1明显低于非浸润型(P<0.05)。并且,肿瘤组织ERCC1和RRM1表达水平与肿瘤分期和分级密切相关(P<0.05),而与患者性别、年龄、肿瘤直径无关(P>0.05)。针对非浸润型患者灌注后共复发7例(14.0%),复发组患者肿瘤组织RRM1表达水平明显高于无复发组,而ERCC1水平明显低于无复发组(P<0.05)。

结论

膀胱癌患者肿瘤组织ERCC1低表达和RRM1高表达不仅与肿瘤分期和病理分级密切相关,还与吉西他滨的灌注疗效有关;检测ERCC1和RRM1表达对早期预测灌注效果,延长患者生存时间具有重要的参考价值。

Objective

To explore the expression of excision repair cross complementing one (ERCC1) and ribonucleotide reductase M1(RRM1) genes in bladder cancer and the relationship with the chemotherapy efficacy of gemcitabine intravesical infusion in non-muscle invasive bladder cancer.

Methods

A total of 86 patients diagnosed as bladder cancer from July 2014 to July 2018 were enrolled in the retrospective study, including 50 patients with nonmuscle-invasive type and 36 patients with invasive bladder cancer, at the same time 30 cases of benign bladder tumor were enrolled. For patients with non-invasive cancer, transurethral resection of bladder tumor and bladder perfusion of gemcitabine chemotherapy were used. The quantitative expressions of ERCC1 and RRM1 mRNAs were detected by real-time fluorescence quantitative PCR. The follow-up time was 15-63 months, median time was 41.5 months. Progression free survival time(PFS), median survival time, total recurrence rate and survival rate were recorded. The correlation between ERCC1 and RRM1 gene expressions and perfusion effect were analyzed.

Results

Compared with patients with benign bladder tumor, RRM1 was higher expressed and ERCC1 was lower in patients with bladder cancer, and RRM1 was significantly higher in invasive patients than non-invasive patients (P<0.05), ERCC1 was lower than non-invasive patients (P<0.05). Moreover,expression levels of ERCC1 and RRM1 were closely related to tumor stage and grade, but not related to patient's gender, age and tumor diameter (P<0.05). 7 cases (7/50) after perfusion recurred. The expression level of RRM1 was significantly higher in recurrence group than non-recurrence group, while ERCC1 was lower than non-recurrence group (P<0.05).

Conclusion

The low expression of ERCC1 and high expression of RRM1 in bladder cancer are not only closely related to tumor stage and pathological grade, but also to perfusion effect of gemcitabine. The detection of ERCC1 and RRM1 expressions has important reference value for early prediction of chemotherapy effect, and prolonging survival time of patients.
