OBJECTIVES: Microvascular invasion (MVI) has previously been reported to be related to cancer prognosis; however, its significance in patients with dual-phenotype hepatocellular carcinoma (DPHCC) remains uncharacterized. We studied the role of MVI in the survival of patients diagnosed with DPHCC in Fujian, China, which has a high incidence of HCC.
METHODS: Patients with DPHCC (n = 84) who had undergone surgical interventions at the 900th Hospital of the Joint Logistic Support Force between 2013 and 2019 were retrospectively analyzed using the log-rank test and Kaplan-Meier method. Univariate and multivariate Cox model analyses were also conducted to further understand the correlation between MVI and patient survival.
RESULTS: Our results indicated that MVI was related to poor survival. According to the univariate analysis, MVI, the number of tumor lesions, necrosis, differentiation, peripheral hepatic fibrosis, the expression of cytokeratin 19 (CK19), and serum levels of both ɑ-fetoprotein (AFP) and cancer antigen-199 showed a strong correlation with overall survival. Necrosis and serum AFP levels were strongly related to an increased risk of death, according to the multivariate analysis. Tumor size; the number of tumor lesions; differentiation; peripheral hepatic fibrosis; liver capsule invasion; and expression of CK19, vascular endothelial growth factor, CK7, and mucin 1 showed a correlation with MVI, per the outcomes of χ2 tests.
CONCLUSIONS: Microvascular invasion may correlate with the survival of patients with DPHCC and could potentially serve as a prognostic predictor of survival.
