Abstract

Upper tract urothelial carcinoma (UTUC) is a relatively rare and highly aggressive tumor. However, the prognosis of UTUC is rarely predicted accurately due to the lack of reliable biomarkers. C‑reactive protein (CRP) has been found to be correlated with several types of cancer. In this study, we performed a systematic review and meta‑analysis to determine the association between CRP levels and prognosis in UTUC. a computerized search was conducted through PubMed, Embase, Web of Science, the Cochrane Library and CBM databases to identify clinical studies that have evaluated the association between preoperative CRP levels and prognosis of UTUC. The prognostic outcomes included recurrence‑free survival (RFS), cancer‑specific survival (CSS) and overall survival (OS). We extracted and synthesized corresponding hazard ratios (HRs) and confidence intervals (CIs) using Review Manager 5.3 software. We identified 7 retrospective cohort studies including a total of 1,919 patients and analyzed these studies using univariate and multivariate models. Our meta‑analysis results revealed that RFS and CSS were significantly different between patients with elevated CRP levels and those with low CRP levels (P<0.0001 and P<0.00001, respectively); however, that was not the case for OS (P=0.22) in the multivariate or the univariate model. The pooled HR of RFS was 2.90 (95% CI: 1.87‑4.51, P<0.00001) in the univariate analysis and 1.57 (95% CI: 1.26‑1.97, P<0.0001) in the multivariate analysis. The pooled HRs of CSS were 2.78 (95% CI: 1.75‑4.43, P<0.0001) and 1.64 (95% CI: 1.32‑2.03, P<0.00001) in the univariate and multivariate analysis, respectively. However, the pooled HRs of OS were not significant in the univariate [1.24 (95% CI: 0.72‑2.15, P=0.43)] or the multivariate analysis [1.24 (95% CI: 0.88‑1.75, P=0.22)]. In conclusion, our meta‑analysis results suggested that CRP level may be a prognostic predictor in UTUC.
