C-reactive protein in liver cancer surgery

Abstract Aims The aim of this article is to review the current state of knowledge with regard to the importance of C-reactive protein (CRP) in patients undergoing hepatic resection for malignancy both in terms of its role as an acute phase reactant and predictor of outcome. Methods An electronic search was performed of the medical literature using the MEDLINE database to identify relevant articles that included the search terms: C-reactive protein; CRP; hepatocellular carcinoma; colorectal liver metastases; hepatic resection; and liver resection. Results The limited published data in relation to CRP and liver resection is contradictory. There are studies correlating an acute phase reactant-type postoperative rise in CRP with both good and poor outcome following colorectal liver metastases resection. In relation to prognosis, the only available publication indicates that a high preoperative CRP is a poor prognostic indicator in relation to patient survival. Data for CRP and resection of HCC is equally as limited with early evidence suggesting a correlation between CRP and stage of disease, and documenting an acute temporary elevation in CRP following resection. Conclusions The importance of CRP as a marker of both early postoperative outcome and long-term prognosis in patients with hepatic malignancies is at present unclear. Further studies are required to clarify the changes and more accurately define the mechanism by which CRP is being up-regulated.
