Abstract
This study is to examine the impact of perioperative (intraoperative/postoperative) blood transfusion on the outcomes of curative hepatectomy for hepatocellular carcinoma. Hepatectomy is a well-established curative treatment for hepatocellular carcinoma, and blood transfusion cannot always be avoided in treating the disease. A retrospective study of patients having curative hepatectomy for hepatocellular carcinoma from January 2010 to December 2019 at a single center was conducted. The patients were stratified by their disease stage. Patients with and without perioperative blood transfusion were matched by propensity-score matching and compared for each disease stage. Univariate and multivariate analyses were performed to identify prognostic factors for overall survival for each stage. A total of 846 patients were studied. Among them, 125 received perioperative blood transfusion and 720 did not. Patients with blood transfusion had worse disease-free and overall survival. After stratification and matching, the ratios of transfusion to non-transfusion were 33:165 (stage 1), 28:140 (stage 2), and 45:90 (stage 3). Perioperative blood transfusion was associated with a higher incidence of postoperative complications in all three disease stages (p = 0.004/0.006/0.017), and hence longer hospitalization (p < 0.001 in all stages), but had no significant impact on hospital mortality (p = 0.119/0.118/0.723), 90-day mortality (p = 0.259/0.118/0.723), disease-free survival (p = 0.128/0.826/0.511), or overall survival (p = 0.869/0.122/0.122) in any disease stage. Prognostic factors for overall survival included tumor size, tumor number, alpha-fetoprotein level, and postoperative complication of grade ≥ 3A. Perioperative blood transfusion was associated with a higher incidence of complications but had no significant impact on survival after curative hepatectomy for hepatocellular carcinoma.
