摘要

Background

Risk factors for intrahepatic recurrence after hepatectomy for HCC are incompletely understood. Intrahepatic lymphatic drainage through the Glisson’s sub-serosal system may represent a pathway favoring intrahepatic spread of cancer cells. This study investigates the prognostic role of Glisson’s capsule invasion by hepatocellular carcinoma (HCC) after hepatectomy.

Methods

Of 192 patients undergoing curative hepatectomy at a single institution between 2010 and 2023, 84 met the inclusion criteria and were retrospectively analyzed. Primary endpoints of intra-hepatic recurrence rate and pattern, and secondary survival endpoints were analyzed between patients with microscopic presence vs. absence of Glisson’s capsule invasion by HCC.

Results

Microscopic tumor invasion of the Glisson’s capsule was found in 39 (46.4%) patients. After a median follow-up of 36 months, 44 (52.4%) patients developed intrahepatic recurrent disease, and most cases (n = 32, 72.7%) occurred as early recurrence (within 15 months). Glisson’s capsule invasion was associated with higher overall (73.5% vs. 56.8%, p = 0.114) and early (55.9% vs. 35.1%, p = 0.079), recurrence rates, and more frequently demonstrated a multifocal pattern of tumor recurrence (75.0% vs. 40.0%, p = 0.019). Glisson’s capsule invasion was the only histopathologic risk factor of multifocal relapse (odds ratio: 4.5, p = 0.022). Kaplan–Meier survival estimates returned an unfavorable median DFS (15.1 vs. 47.6 months, p = 0.034) and OS (50.4 vs. 76.3 months, p = 0.074) in case of Glisson’s capsule invasion.

Conclusions

Glisson’s capsule invasion by the primary HCC is associated with a pattern of multifocal intrahepatic recurrence and unfavorable survival. Further studies are required to validate its prognostic role and surgical implications.
