[Impact of Postoperative Inflammatory Status on Colorectal Cancer Prognosis].

To clarify the prognostic impact of postoperative inflammatory status, serum CRP levels on POD3 after radical resection (POD3 CRP)were evaluated as an indicator of inflammatory response after surgery in patients with colorectal cancer. Of the colorectal cancer patients who underwent radical resection at our department between 2000 and 2015, 916 patients with Stage Ⅰto Ⅳdisease were included in the analyses. The patients were divided into 2 groups according to high and low POD3 CRP levels. The POD3 CRP levels of the patients were analyzed for the 75th percentile that was 12.16mg/dL(range, 0.06- 33.78). The cancer-specific 5-year survival rate was 80.6%in patients in the high group and 90.5%in those in the low group, indicating poor prognosis in patients with high values. POD3 CRP levels were an independent prognostic factor in the multivariate analysis. It was suggested that the degree of inflammation after surgery influences the postoperative prognosis after radical resection for colorectal cancer.
