AI Article Synopsis
- The study aimed to investigate the causes of hepatocellular carcinoma (HCC) in Japanese patients with non-viral liver diseases, focusing on factors like obesity, lifestyle diseases, and alcohol consumption.
- A survey of 14,530 HCC patients revealed differing characteristics among three groups: those with alcoholic liver disease (ALC-HCC), nonalcoholic fatty liver disease (NAFLD-HCC), and chronic liver disease of unknown cause.
- The findings showed that ALC-HCC and unknown HCC had distinct clinical profiles, suggesting that even moderate alcohol consumption could play a significant role in the development of liver cancer.
Article Abstract
Purpose: To clarify the etiology of hepatocellular carcinoma (HCC) in Japanese patients with non-viral liver disease, we performed a nationwide survey. The influence of obesity, lifestyle-related diseases, and alcohol consumption was focused on.
Methods: A nationwide survey of 14,530 HCC patients was conducted in 2009. Clinical features were studied for HCC patients with nonalcoholic fatty liver disease (NAFLD-HCC; n = 292), alcoholic liver disease (ALC-HCC; n = 991), and chronic liver disease of unknown etiology (unknown HCC; n = 614). The unknown HCC was divided into two subgroups, a no alcohol intake group and a modest alcohol intake group.
Results: ALC-HCC accounted for 7.2% of all HCC, followed by unknown HCC (5.1%) and NAFLD-HCC (2.0%). The characteristics of these three groups were clearly different (median age was 72 years for NAFLD-HCC, 68 years for ALC-HCC, and 73 years for unknown HCC, p < 0.01; female gender was 38, 4, and 37%, respectively, p < 0.01). Obesity and lifestyle-related diseases were significantly more frequent in NAFLD-HCC than in ALC-HCC and unknown HCC. The no alcohol intake subgroup of unknown HCC showed female predominance (58%) and was older, without a high prevalence of obesity and lifestyle-related diseases. In contrast, the modest alcohol intake subgroup showed the same trends regarding gender, body mass index, prevalence of lifestyle-related diseases, and liver function as the ALC-HCC group.
Conclusions: The clinical features of ALC-HCC, NAFLD-HCC, and unknown HCC were clearly different. Modest intake of alcohol might have a more significant role in hepatic carcinogenesis than is presently thought.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) has become the most common chronic liver disease worldwide. The pan-immune-inflammation value (PIV) has been proposed as a biomarker for assessing immune status and inflammation. There is currently no evidence regarding the effect of PIV on the risk of MASLD.

Background: Mucopolysaccharidosis type I (MPS I - IDUA gene) is a rare autosomal recessive lysosomal storage disorder. Clinical symptoms, including visceral overload, are progressive and typically begin postnatally. Descriptions of hepatosplenomegaly associated with lysosomal pathology are uncommon during the prenatal period.

Purpose Of Review: Review the latest data regarding the intersection of adipose tissue (AT) and iron to meet the needs of AT metabolism and the progression of related diseases.
Recent Findings: Iron is involved in fundamental biological metabolic processes and is precisely fine-tuned within the body to maintain cellular, tissue and even systemic iron homeostasis. AT not only serves as an energy storage depot but also represents the largest endocrine organ in the human body, maintaining systemic metabolic homeostasis.

Lysine lactylation plays critical roles in various diseases, including cancer. Our previous study showed that lactylation of non-histone ABCF1 may be involved in hepatocellular carcinoma (HCC) progression. In this study, we evaluated the prognostic value of ABCF1-K430la in HCC using immunohistochemical staining and performed amino acid point mutations, multi-omics crossover, and biochemical experiments to investigate its biological role and underlying mechanism.
