Impact of alcohol abstinence on survival after hepatic resection for hepatocellular carcinoma in patients with alcohol-related liver disease

Background

This study aimed to evaluate the prognostic impact of alcohol abstinence on survival after hepatic resection for hepatocellular carcinoma (HCC) in patients with alcohol-related liver disease (ALD).

Patients and methods

In total, 92 patients with ALD-HCC who underwent initial and curative hepatic resection were identified, including 56 and 36 patients with and without alcohol abstinence, respectively.

Results

The 3-, 5-, and 7-year recurrence-free survival (RFS) were 46%, 43%, and 37% in the abstinence group, and 61%, 36%, and 36% in the non-abstinence group, respectively (p = 0.71). The 3-, 5-, and 7-year overall survival (OS) were 91%, 76%, and 66% in the abstinence group, and 87%, 57%, and 44% in the non-abstinence group, respectively (p = 0.023). Multivariate analysis revealed that non-abstinence was an independent prognostic factor for OS (P = 0.026). The incidence rate of liver-related death including HCC-specific death, liver failure, and renal failure in cirrhosis (hepatorenal syndrome) between the non-abstinence and abstinence groups were 41.7% vs. 19.6% (p = 0.032). Worsening of the Child–Pugh grade at intrahepatic recurrence was more frequently observed in the non-abstinence (33.3%) than that in the abstinence group (6.5%) (p = 0.039).

Conclusions

Alcohol abstinence might improve the long-term survival of patients with ALD-HCC undergoing hepatic resection.

•

Non-abstinence after surgery was an independent prognostic factor for overall survival with a 2.2-fold increased risk.

•

Worsening of Child–Pugh grade at intrahepatic recurrence was less frequently observed in the abstinent patients.

•

Hepatic resection tended to be more frequently performed for the treatment of HCC recurrence in the abstinent patients.

•

The incidence rate of liver-related death was significantly lower in the abstinent patients.
