Nutritional status and incidence of hepatocellular carcinoma in patients with compensated liver cirrhosis.

Background: Malnutrition in patients with liver cirrhosis (LC) and/or hepatocellular carcinoma (HCC) has been associated with adverse outcomes. However, there is little information on the incidence of HCC during the compensated phase of LC in relation to the nutritional status.

Aim: To evaluate the association between the incidence of HCC in compensated LC and their nutritional status.

Methods: Patients with compensated liver cirrhosis with no previous history of ascites, hepatic encephalopathy, or variceal bleeding attending the Gastroenterology outpatient service at Centro Medico Nacional Siglo XXI were included in a prospective cohort. Clinical and nutritional parameters were collected, including the Royal Free Hospital Subjective Global Assessment (RFH-SGA) as an indicator of protein-calorie malnutrition and the triceps skinfold thickness, which classified patients as having normal subcutaneous adipose tissue (SAT), above average SAT, and below average SAT. Follow-up was censored at the time of HCC diagnosis or LC decompensation.

Results: About 31/187 (16.0 %) and 22/187 (11.8 %) patients were categorized as having above- or below-average SAT at baseline, respectively. 10/187 patients (5.3 %) developed HCC during the compensated phase of LC at a median of 22 months (IQR: 10.0-36.75). A higher risk of HCC was observed in subjects below average SAT (HR: 4.064, CI 95 %: 1.012-16.317, p = 0.048). After adjusting the Cox models for age and α-fetoprotein at baseline, the statistical significance of the association between SAT and HCC was not modified.

Conclusion: These results suggest that decreased SAT may precede the diagnosis of HCC in compensated LC.
