Microscopic vascular invasion may not be associated with survival of patients undergoing resection for solitary hepatoma of ≤ 2 cm.

ABSTRACT:

Background/objective

To determine the impact of microvascular invasion (MVI) on outcome in patients with solitary hepatocellular carcinoma (HCC) of ≤ 2 cm undergoing liver resection (LR).

Methods

This retrospective study enrolled consecutive patients between 2007-2019 with newly diagnosed solitary HCC ≤ 2 cm who were undergoing LR at our institution. Overall survival (OS) and recurrent-free survival (RFS) were compared between patients with or without MVI.

Results

Of the 229 patients included in this study, 71 had MVI. The median follow-up period was 28.8 months (interquartile range: 13.5-70.1). Although the 90-day mortality rate was 0, 18 deaths occurred during the study, and the 5-year survival rate was 87.1%. Tumor recurrence occurred in 45 cases, and 5-year RFS wa
