非肌层浸润膀胱癌组织中ROC1,UBC9水平表达与临床病理学特征及肿瘤电切术预后的相关性研究
Expression of ROC1,UBC9 in Non-muscle Invasive Bladder Cancer Tissues and Their Correlation with Clinicopathological Characteristics and Prognosis of Tumor Resection
摘要
Abstract
Objective To study the expression of regulator of cullins-1(ROC1)and ubiquitin binding enzyme 9(UBC9)in non-muscle invasive bladder cancer(NMIBC)and their relationship with clinicopathological features and prognostic value of transurethral resection of bladder tumor(TURBT).Methods Retrospective analysis was conducted on 104 patients with NMIBC who underwent TURBT at Northwest University First Hospital from April 2018 to February 2021.Immunohistochemistry was used to detect the expression of ROC1 and UBC9 in tissues.Follow-up was conducted for 3 years,and Kaplan-Meier curve analysis and COX regression analysis were used to identify factors affecting the prognosis of NMIBC patients.Results The positive rates of ROC1(67.31%)and UBC9(69.23%)in NMIBC cancer tissues were higher than those in adjacent tissues(9.62%,7.69%),and the differences were statistically significant(χ2=73.125,83.200,all P<0.001).There was a positive correlation between the expression of ROC1 and UBC9 in NMIBC cancer(r=0.719,P<0.001).The positivity rates of ROC1(87.23%,90.00%)and UBC9(89.36%,88.33%)in cancer tissues with a maximum tumor diameter of≥2cm,T1 stage were higher than those in cancer tissues with a maximum tumor diameter of<2cm(50.88%,52.63%),Ta/Tis stage(36.36%,43.18%),and the difference were statistically significant(χ2=15.474～33.188,all P<0.05).After TURBT surgery,there were 29 cases of local recurrence,10 cases of metastasis,and 2 deaths of bladder cancer,the 3-year progression-free survival(PFS)rate was 60.58%(63/104).The 3-year PFS of NMIBC patients in the ROC1 positive and negative groups was 47.14%(33/70)and 88.24%(30/34),and the 3-year PFS of patients in the UBC9 positive and negative groups was 47.22%(34/72)and 90.63%(29/32),the differences were statistically significant(Log-rank χ2=15.341,15.931,all P<0.001).Multivariate COX regression analysis showed that ROC1 positivity,UBC9 positivity,maximum tumor diameter≥2cm and T1 phase were risk factors affecting the prognosis of NMIBC patients(all P<0.001).Conclusion The expression of ROC1 and UBC9 is elevated in NMIBC,which is related to the maximum diameter and stage of the tumor.Combined detection of ROC1 and UBC9 can help evaluate the prognosis of NMIBC patients.关键词
