Diagnostic value of urine cyclic RNA-0071196 for bladder urothelial carcinoma

Objective To investigate the diagnostic value of urine cyclic RNA-0071196 (circRNA-0071196) in the patients with bladder urothelial carcinoma (BUC).

Method The expression of circRNA-0071196 was detected in the urine samples using qRT-PCR from 40 BUC patients and 30 non-UBC patients at our department from December 2018 to September 2021.

The expression difference of circRNA-0071196 was compared between the two groups, and the relationship between the expression of circRNA-0071196 in the urine of UBC patients and the clinical pathological characteristics was analyzed.

Results (1) The expression of circRNA-0071196 in the urine of BUC group was significantly higher than that in the non-BUC group ( P  < 0.05).

(2) The expression of circRNA-0071196 in the urine of BUC group was not related to age, sex, or lymph node metastasis ( P  > 0.05).

(3) The expression of circRNA-0071196 in the urine of BUC group was related to tumor T stage, tumor grade and muscle invasion.

(4) The urine circRNA-0071196 expression effectively distinguished BUC patients from non-BUC patients.

Conclusion The elevated expression of urine circRNA-0071196 in BUC patients indicates that circRNA-0071196 has promising potential as a non-invasive urinary biomarker for detecting BUC.
