Background: Bladder cancer is a common urinary cancer, and most patients suffer tumor recurrence after surgery. Identifying more prognostic biomarkers is an essential task for precious treatment.
Objective: To evaluate the expression and clinical significance of GPR123, Angiotensin-I a type of adhesion G protein-coupled receptors (aGPCRs), in bladder cancer.
Methods: The expressions of GPR123 in two retrospective cohorts comprised of 150 and 56 patients with bladder cancer respectively, were detected with and immunohistochemistry (IHC). Moreover, GPR123 mRNAs in 11 non-muscle-invasive bladder cancers (NMIBCs) and 11 muscle-invasive bladder cancers (MIBCs) were detected with qRT-PCR. The correlation between GPR123 and the clinicopathological characters was estimated by Chi-square test. The significance of GPR123 and other clinicopathological characters in recurrence and prognosis of bladder cancer was evaluated by univariate and multivariate analyses.
Results: GPR123 was mainly expressed in the cell membrane of bladder cancer. The percentages of high GPR123 expression in NMIBC and MIBC were 38.32 and 55.81?% in cohort 1, and 16.00 and 43.90?% in cohort 2. With qRT-PCR and IHC, we showed that GPR123 expression in MIBC was significantly higher than that in NMIBC. GPR123 was significantly associated with T and M stage of bladder cancer. GPR123 expression was all correlated with recurrence (disease-free survival rate), and prognosis (overall survival rate). High GPR123 expression was identified as independent biomarker indicating easier recurrence and poorer prognosis.
Conclusions: GPR123 was an independent biomarker of bladder cancer for recurrence and prognosis, indicating that GPR123 detection with IHC after operation could help find the high-risk patients and direct the post-operational surveillance.
