Sumario:PURPOSE: The influence of resection margin (RM) width on the prognosis of solitary hepatocellular carcinoma (HCC) following anatomical resection (AR) has yet to be determined. Therefore, we conducted a real-world study to identify the optimal RM width and assess its impact on the outcomes of solitary HCC patients undergoing AR. METHODS: The data pertaining to patients diagnosed with solitary HCC who underwent AR between December 2012 and December 2015 were retrospectively collected. The optimal cutoff value for the width of the RM was determined using X-tile software. The Kaplan-Meier method was utilized to compare the overall survival (OS) and disease-free survival (DFS) between the narrow and wide RM groups. Additionally, propensity score matching (PSM) was performed to minimize potential bias in the data. RESULTS: Of the 1033 patients who met the inclusion criteria, 293 (28.4%) were categorized into the narrow RM group (≤4 mm) and 740 (71.6%) into the wide RM group (> 4mm). Before and after PSM, there were no significant differences in OS and DFS between the two groups (before PSM: OS, HR=0.78, P=0.071; DFS, HR=0.95, P=0.620; after PSM: OS, HR=0.77, P=0.150; DFS, HR=0.90, P=0.470). Multivariate analysis demonstrated that RM width was not an independent risk factor for DFS and OS both before and after PSM (all P>0.05). However, subgroup analyses revealed that patients with ALBI grade 1, absence of cirrhosis, and AJCC stage II significantly benefited from wide RM in OS (all P< 0.05). Similarly, patients without HBV infection and absence of cirrhosis also exhibited significant benefits from wide RM in DFS (both P< 0.05). CONCLUSION: In patients with solitary HCC undergoing AR, the width of the RM does not appear to have a significant impact on their prognosis. However, in certain selected patients, a wider RM may confer benefits.
