Background: The clinical value of the controlling nutritional status (CONUT) score in hepatocellular carcinoma (HCC) has increased. The aim of this meta-analysis was to systematically review the association between the CONUT score and outcomes in patients undergoing hepatectomy for HCC. Methods: Embase, Medline Ovid, Web of Science, Cochrane CENTRAL, and Google Scholar were systematically searched. Random effects meta-analyses were conducted to examine the prognostic value of the CONUT score in HCC patients. Results: A total of five studies including 4679 patients were found to be eligible and analyzed in the meta-analysis. The CONUT score was significantly associated with overall survival (HR 1.78, 95%CI = 1.20-2.64, P = 0.004, I 2 = 79%), recurrence-free survival (HR 1.34, 95%CI = 1.17-1.53, P < 0.001, I 2 = 16%) and postoperative major complications (OR 1.85, 95%CI: 1.19-2.87, P = 0.006, I 2 = 72%) in HCC patients. Moreover, the CONUT score was associated with the Child-Pugh classification, liver cirrhosis, ICGR15, and tumor differentiation. However, it was not associated with tumor size, tumor number, and microvascular invasion. Conclusions: The CONUT score is an independent prognostic indicator of the prognosis and is associated with postoperative major complications and hepatic functional reserve in HCC patients.
