Nutritional status in patients with hepatocellular carcinoma: Potential relevance for clinical outcome.

BACKGROUND

Impaired nutritional status is a risk factor for unfavorable outcome in cirrhosis.

METHODS

In this prospective cohort study in hepatocellular carcinoma patients referred for tumor-specific therapy, nutritional status was assessed before and 3 months post-treatment using 4 complementary tools: hand-grip strength (HGS), Liver Frailty Index (LFI), Patient-Generated Subjective Global Assessment (PG-SGA) and skeletal muscle index (L3-SMI). Uni- and multivariable analyses were performed using Kaplan Meier curves and Cox's regression analyses with correction for Barcelona Clinic Liver Cancer (BCLC) stage, alpha-fetoprotein and age.

RESULTS

56 patients were evaluated at baseline and 38 patients 3 months post-treatment. Baseline BCLC stage was 0 in 14%, A in 27%, B in 36%, C in 21%, and D in 2%. HGS, LFI, PG-SGA and L3-SMI were impaired in 13%, 95%, 21% and 71% respectively. Of all patients, 52% died after (median, range) 373 (32-962) days. Of the nutritional assessment tools, only HGS was independently associated with complication-free survival (HR 0.304, 95%CI 0.10-0.88: p = 0.028) and, approaching significance, with overall survival (HR 0.323, 95%CI 0.103-1.008: p = 0.052). Tumor-specific therapy was administered in 50 patients (20% radiofrequency / microwave ablation, 4% resection, 74% transarterial radio- or chemoembolization, 2% sorafenib). Three months post-treatment, complete response occurred in 44%, partial response in 20%, stable disease in 20% and progressive disease in 16%. Child-Pugh scores deteriorated and such deterioration was independently associated with reduced overall and complication-free survival.

CONCLUSIONS

reduced baseline HGS and deteriorated post-treatment Child-Pugh score are associated with reduced overall and complication-free survival in HCC.
