{Abstract}: <B>BACKGROUND: </B>Still now, the efficacy of anatomic resection (AR) for hepatocellular carcinoma (HCC) is controversial. The aim of this study is to examine it in our cohort and detect an optimal indicator for AR.<BR><B>METHODS: </B>The present study included 656 patients with primary HCC within Milan criteria who underwent hepatectomy from 2000 to 2019. Our cohort was divided into AR (n = 378) and non-anatomic resection (NAR) (n = 278) groups, and 1:1 propensity score matching (PSM) was performed to minimize the effect of potential confounders. Recurrence-free survival (RFS), overall survival (OS), and a preoperative indicator for AR were examined.<BR><B>RESULTS: </B>210 patients from each group were well-matched, and preoperative confounding factors were balanced between the two groups. There was no significant difference in RFS and OS between the two groups before (RFS; HR = 0.89 P = 0.25, OS; HR = 1.08 P = 0.64) and after PSM (RFS; HR = 0.93 P = 0.60, OS; HR = 1.07 P = 0.75). Subgroup analysis showed that the survival improvement effect of AR was observed in cases with a fucosylated fraction of alfa-fetoprotein (AFP-L3) > 10% and poorly differentiation (P for interaction <0.05). Moreover, the logistic regression analysis showed that preoperative AFP-L3 > 10% was an independent predictor for poorly differentiation (OR = 2.58, P = 0.03).<BR><B>CONCLUSIONS: </B>The efficacy of AR for patients with primary HCC within Milan criteria was not shown. But it was suggested that AFP-L3 > 10% might be a preoperative indicator of AR for HCC within Milan criteria.
