Abstract:
Objective:To study the predictive value of systemic immune-inflammation index (SII), alpha-fetoprotein (AFP) and tumor diameter on microvascular invasion (MVI) in patients with resectable hepatocellular carcinoma (HCC), with an aim to establish a preoperative prediction model.Methods:The clinical data of 283 patients who underwent hepatectomy at the First Affiliated Hospital of Nanchang University from September 2017 to September 2020 were retrospectively analyzed. In the 283 patients with HCC who were included into this study, 249 were males and 34 were females, aged (53.7±11.0) years. Using postoperative pathology findings, these patients were divided into two groups: the MVI negative group ( n=140) and the MVI positive group ( n=143). Correlation between MVI and related indicators was analyzed using logistic regression analysis. The prediction model of MVI was then established by selecting independent risk factors. Univariate and multivariate analysis of recurrence-free survival (RFS) were performed using the Cox proportional hazards regression model. Results:Multivariate logistic regression analysis showed that AFP>400 ng/ml ( OR=2.304, 95% CI: 1.329-3.995, P=0.003), SII>376.30×10 9/L ( OR=2.249, 95% CI: 1.299-3.894, P=0.004) and tumor diameter>5 cm ( OR=2.728, 95% CI: 1.587-4.687, P<0.001) were independent risk factors for MVI. The Cox proportional hazards regression model showed that AFP ( HR=1.663, 95% CI: 1.063-2.602, P=0.026) and SII ( HR=1.851, 95% CI: 1.173-2.920, P=0.008) were independent risk factors for RFS in HCC patients. The sensitivity and specificity of the model based on SII, AFP and tumor diameter were 59.4% and 75.7%, respectively. Conclusions:SII, AFP and tumor diameter were closely related to occurrence of MVI in patients with HCC. AFP and SII were independent prognostic factors of RFS. This prediction model has certain predictive values for occurrence of MVI and prognosis of HCC patients.
