OBJECTIVE: This meta-analysis evaluates the prognosis value of C-reactive protein to albumin ratio (CAR) in colorectal cancer. METHODS: Embase, PubMed, and Web of Science were searched. Pooled hazard ratios (HRs) with their corresponding 95% confidence intervals (CIs) were used as effective values. RESULTS: A total of 6 studies with 1942 patients were included in this study. Pooled results revealed that elevated pretreatment CAR was related with poorer overall survival (OS) (HR: 2.09, 95%CI: 1.78-2.45, P < .001) in colorectal cancer. CONCLUSION: Elevated CAR was associated with poor prognosis in colorectal cancer. Thus CAR might be used as a prognostic system and classification of colorectal patients in clinical potential.
