Abstract:

PURPOSE: C-reactive protein (CRP) is widely known as a major nonspecific systemic inflammatory marker. A number of previous studies have suggested that elevated preoperative CRP is associated with poor prognosis in colorectal cancer. We aimed to explore the effects of preoperative CRP on colorectal cancer survival through a meta-analysis.

METHODS: A total of 21 studies, including a total of 3934 colorectal cancer patients, were eligible. The multivariate-adjusted hazard ratios (HRs) and 95 % confidence intervals (CIs) of selected studies were used to assess the summary estimates of the association between preoperative CRP and colorectal cancer survival.

RESULTS: The pooled HRs of elevated preoperative CRP for earlier stage patients were 2.04 (95 % CI 1.45-2.86) for OS, 4.37 (95 % CI 2.63-7.27) for CSS, and 1.88 (95 % CI 0.97-3.67) for DFS. The pooled HRs of a higher Glasgow Prognostic Score (GPS)/modified GPS (mGPS) for earlier stage patients were 2.20 (95 % CI 1.61-3.02) for OS and 1.80 (95 % CI 1.37-2.37) for CSS. The association between elevated preoperative CRP and poor survival was observed in patients with advanced cancer. Elevated CRP and GPS/mGPS were significantly associated with poor survival.

CONCLUSION: Preoperative CRP and its related markers, GPS and mGPS, were significantly associated with the survival of colorectal cancer surgery patients. The HRs of GPS and mGPS were highly homogeneous across studies for all survival types. Thus, GPS and mGPS may serve as stable predictors of the survival of colorectal cancer surgery patients.
