Tóm tắt

 OBJECTIVES: To define how dynamic changes in pre versus postoperative serum aspartate aminotransferase (AST) and alanine transaminase (ALT) levels may impact postoperative morbidity after curative-intent resection of hepatocellular carcinoma (HCC). BACKGROUND: Hepatic ischemia/reperfusion can occur at the time of liver resection and may be associated with adverse outcomes after liver resection. METHODS: Patients who underwent curative resection for HCC between 2010 and 2020 were identified from an international multi-institutional database. Changes in AST and ALT (CAA) on postoperative day 3 versus preoperative values ( ) were calculated using the formula: based on a fusion index through the Euclidean norm, which was examined relative to the Comprehensive Complication Index (CCI). The impact of CAA on CCI was assessed by the restricted cubic spline regression and Random Forest analyses. RESULTS: A total of 759 patients were included in the analytic cohort. Median CAA was 1.7 (range: 0.9-3.25)
  431 (56.8%) patients had a CAA <
 2 215 (28.3%) patients with CAA 2 to 5, and 113 (14.9%) patients had CAA ≥5. The incidence of postoperative complications was 65.0% (n = 493) with a median CCI of 20.9 (interquartile range: 20.9-33.5). Spline regression analysis demonstrated a nonlinear incremental association between CAA and CCI. The optimal cutoff value of CAA was 5, identified by the recursive partitioning technique. After adjusting for other competing risk factors, CAA ≥5 remained strongly associated with the risk of postoperative complications (reference CAA <
 5, odds ratio: 1.63, 95% CI: 1.05-2.55, P = 0.03). In fact, the use of CAA to predict postoperative complications was very good in both the derivative (area under the curve: 0.88) and external (area under curve: 0.86) cohorts (n = 1137). CONCLUSIONS: CAA was an independent predictor of CCI after liver resection for HCC. The use of routine laboratories, such as AST and ALT, can help identify patients at the highest risk of postoperative complications after HCC resection.
