RESUMEN
AIMS: Hepatocellular carcinoma (HCC) develops even in patients with hepatitis C virus (HCV) eradication by direct-acting antiviral agents. Fatty liver and metabolic dysfunction are becoming major etiologies of HCC. We aimed to evaluate the impact of metabolic dysfunction-associated steatotic liver disease (MASLD), a new definition of steatotic liver disease, on the development of HCC after HCV eradication. METHODS: We enrolled 1280 elderly patients with HCV eradication and no history of HCC. We evaluated α-fetoprotein (AFP), Fibrosis-4 index and MASLD after 24 weeks of sustained virological response. Decision tree analysis was used to investigate factors associated with HCC development after HCV eradication. RESULTS: A total of 86 patients (6.7%) developed HCC during the follow-up period (35.8 ± 23.7 months). On multivariate analysis, serum AFP level (HR 1.08, CI 1.04-1.11, P = 0.0008), Fibrosis-4 index (HR 1.17, CI 1.08-1.26, P = 0.0007), and MASLD (HR 3.04, CI 1.40-6.58, P = 0.0125) at 24 weeks of sustained virological response were independent factors associated with HCC development. In decision tree analysis, the initial classifier for HCC development was AFP ≥7 ng/mL. However, in patients with AFP <7 ng/mL, MASLD, rather than Fibrosis-4 index, was the classifier for HCC development. No significant difference was observed in the cumulative incidence of HCC between patients with AFP ≥7 ng/mL and patients with AFP <7 ng/mL and MASLD. CONCLUSION: MASLD at 24 weeks of sustained virological response is a risk factor for HCC development in elderly patients with HCV eradication. Additionally, decision tree analysis revealed that MASLD was associated with HCC development, even in patients with serum AFP levels <7 ng/mL.
RESUMEN
AIM: The aim of this study was to evaluate the long-term outcome of elderly patients with hepatocellular carcinoma (HCC) aged 75 years or older. METHODS: The study included 422 patients with HCC, who were divided into two age groups: 75 years or older (n = 140) and younger than 75 (n = 282). Outcomes were compared between the two groups. RESULTS: The number of elderly patients treated with supportive care alone (33 patients; 24%) was significantly higher than younger patients (30 patients; 11%, P < 0.01). The 1-, 3-, 5- and 7-year overall survival rates of the elderly patients (81%, 55%, 39% and 23%, respectively) were worse than those of younger patients (85%, 64%, 49% and 36%, respectively, P = 0.042). However, the overall survival rate of the elderly group after excluding 63 patients treated with supportive care alone, was similar to that of the younger group (P = 0.615). Multivariate analysis identified age, total bilirubin levels, albumin levels, serum des-γ-carboxy prothrombin levels, tumor size, number of HCC nodules, vascular invasion, extrahepatic metastasis and treatment modality as independent and significant factors of overall survival. CONCLUSION: Advanced age is a negative prognostic factor in patients with HCC due to the tendency for frequent use of conservative treatment rather than locoregional or surgical treatment.
RESUMEN
AIM: Radiofrequency ablation therapy (RFA) combined with transarterial chemoembolization (TACE) (combination therapy) is effective for early-stage hepatocellular carcinoma (HCC). The aim of this study was to compare the long-term effects of combination therapy with supportive care alone for intermediate HCC. METHODS: The study included 58 patients with intermediate HCC who received combination therapy (n = 34) or supportive care alone (n = 24). The inclusion criteria were a single nodule of more than 50 mm in diameter or two to three nodules, each measuring more than 30 mm in diameter, or more than three nodules, no vascular invasion and no extrahepatic metastasis. RESULTS: The overall survival rates at 1, 2, 3 and 5 years of the combination therapy group (91%, 65%, 53% and 27%, respectively) were significantly better (P < 0.0001) than those of the supportive care group (42%, 8%, 8% and 0%, respectively). Multivariate analysis identified treatment modality (combination therapy vs supportive care alone: P < 0.0001, risk ratio [RR] = 4.290 [95% confidence interval [CI] = 2.157-8.529]) and serum α-fetoprotein (P = 0.017, RR = 2.318 [95% CI = 1.166-4.610]) as independent and significant factors of overall survival. CONCLUSION: The combination of TACE and RFA is a safe and effective therapy in patients with intermediate HCC.
