Core Viewpoint - The report published in The Lancet highlights the urgent need for comprehensive strategies to prevent and treat hepatocellular carcinoma (HCC), predicting a doubling of global cases by 2025 if no action is taken [2][6]. Group 1: Current Situation and Statistics - HCC is the sixth most common cancer globally and the third leading cause of cancer-related deaths, with 870,000 new cases and 760,000 deaths reported in 2022. Projections indicate that by 2050, new cases could rise to 1.52 million, and deaths could reach 1.37 million [8]. - The report indicates that over 70% of HCC patients are diagnosed at an advanced stage, resulting in a 5-year survival rate of only 5%-30% [13]. Group 2: Causes and Trends - By 2050, hepatitis B virus (HBV) will remain the primary cause of HCC, but its proportion is expected to decrease from 39.0% in 2022 to 36.9%. Conversely, alcohol-related HCC cases are projected to increase from 18.8% to 21.1%, and cases related to metabolic dysfunction-associated fatty liver disease (MASH) are expected to rise from 8% to 10.8% [10][11]. Group 3: Prevention and Early Detection - The report emphasizes that over 60% of HCC cases are preventable through the control of HBV, HCV, alcohol consumption, and fatty liver disease. For instance, in 2022, more than 540,000 of the 870,000 new cases were avoidable [15]. - Early screening can triple survival rates, as demonstrated in Japan, where 68% of HCC cases are detected at an early stage, leading to an 80% 5-year survival rate [17]. Group 4: Recommendations and Strategies - The committee has outlined ten actionable recommendations, including strengthening viral hepatitis prevention, reducing alcohol consumption, and improving early detection of HCC [19]. - Specific strategies include universal HBV vaccination, government-led measures to reduce alcohol consumption, and tailored national strategies to address the rising incidence of MASH [20]. Group 5: Stakeholder Involvement - The report stresses that reducing the global burden of HCC will require collaborative efforts from policymakers, healthcare providers, international organizations, researchers, and patient advocacy groups [21].

Core Viewpoint - Spinocerebellar ataxia type 3 (SCA3) is a common hereditary disorder with no effective treatment, leading to significant burdens on patients and healthcare systems [1][2]. Recent research indicates that transcranial alternating current stimulation (tACS) may provide a safe and effective intervention for improving symptoms in SCA3 patients [3][11]. Summary by Sections Disease Overview - SCA3 is caused by the expansion of CAG repeats in the ATXN3 gene, leading to progressive cerebellar ataxia, which manifests as unsteady gait, speech difficulties, swallowing problems, and poor motor accuracy [1]. - Most SCA3 patients lose mobility within 10-20 years of onset, with a survival period of 20-25 years from onset to death [2]. Recent Research Findings - A randomized controlled trial published in Cell Reports Medicine demonstrated that tACS is safe, effective, and well-tolerated, improving the severity of ataxia by modulating brain functional connectivity in SCA3 patients [3][11]. - The study involved 82 SCA3 patients, randomly assigned to receive either active tACS or sham stimulation for 2 weeks, with significant improvements observed in the active group [8]. Clinical Trial Details - The trial was a triple-blind, parallel-group, sham-controlled study assessing the effects of tACS on ataxia severity and quality of life, using functional MRI to evaluate changes in brain connectivity [7]. - Results showed that 80% of participants in the active tACS group met the primary outcome measure, compared to only 10% in the sham group, with significant reductions in SARA scores [8]. Implications for Future Treatment - The findings suggest that tACS could be a promising intervention for SCA3 and potentially other cerebellar disorders, highlighting the need for further research into its long-term effects [11].
