Patients were divided into training (n=441) and validation (n=217) cohorts according to surgical data. Independent risk factors for MVI were identified via univariate and multivariate logistic regression analyses in the training cohort. A novel nomogram was developed based on the independent risk factors identified. Its accuracy was evaluated using a calibration curve and concordance index (C-index). The predictive value was evaluated using the receiver operating characteristic (ROC) curve and decision curve analysis (DCA).Results: Preoperative alpha-fetoprotein > 969 μg/L (P 1.8× 109/L (P=0.002), gamma-glutamyl transpeptidase-to-platelet ratio (GPR) > 0.32 (P=0.001), aspartate aminotransferase-to-platelet ratio (APR) > 0.18 (P 2.30 (P=0.001), and gamma-glutamyl transpeptidase-to-lymphocyte ratio > 29.58 (P 0.32, APR > 0.18, and GAR > 2.30 were independent risk factors for MVI in patients with solitary primary HCC, suggesting their utility as preoperative predictors of MVI. The novel nomogram developed and validated in this study may aid in determining optimal therapeutic approaches for patients with solitary HCC at risk for MVI.Keywords: hepatocellular carcinoma, microvascular invasion, preoperative prediction, nomogram
