Aims: This retrospective study compared the survival between elderly and non‐elderly patients. Methods: A total of 5545 treatment‐naive patients with hepatocellular carcinoma (HCC) who visited 7 different hospitals from January 2000 to December 2018 were included. Patients ≥80 years old were defined as elderly patients. We divided the patients into three groups based on the timing of the initial treatment: Early, middle, and late periods defined as 2000 to 2005, 2006 to 2012, and 2013 to 2018, respectively. Results: There were 132 (8.9%), 405 (17.5%), and 388 (22.2%) elderly patients in the early, middle, and late period, respectively, showing a significant increase over time (p < 0.001). In both elderly and non‐elderly patients, the median albumin‐bilirubin score significantly improved over time and the diagnosis of HCC was made slightly earlier over time. The median overall survival (OS) in elderly patients was 52.8, 42.0, and 45.6 months in the early, middle, and late period, respectively, without a significant improvement (p = 0.17) whereas the OS in non‐elderly patients was significantly improved (p < 0.001). The percentage of elderly patients receiving curative treatments did not significantly increase (p = 0.43), while that of non‐elderly patients did (p = 0.017). Non‐liver‐related death in elderly patients significantly differed among periods (p = 0.023), while liver‐related death did not (p = 0.050). Liver‐ and non‐liver‐related death in non‐elderly patients significantly differed among periods (p < 0.001, p = 0.005). Conclusions: Survival in elderly patients was not improved despite an improvement in their liver function. Curative treatments should be conducted when appropriate after evaluating each elderly patient. [ABSTRACT FROM AUTHOR]

Summary: Background: While surveillance improves the early detection of hepatocellular carcinoma (HCC), it is unclear whether this has improved prognosis in clinical practice. Aims: To investigate the characteristics and prognoses of patients with viral versus non‐viral HCC over the previous two decades in Japan, while HCC surveillance has been active. Methods: This multi‐centre study enrolled 6007 patients initially diagnosed with HCC between 2000 and 2020 at seven high‐volume academic centres. Patients were categorised based on dates of diagnosis: 2000–2006, 2007–2013 and 2014–2020. HCC characteristics and post‐diagnosis survival rates were compared between periods in patients with viral and non‐viral HCC. Results: The percentage of patients with non‐viral HCC increased during the study period. The maximal tumour size and percentage of patients with multinodular HCC decreased significantly over time in the viral HCC group but remained unchanged in the non‐viral HCC group. Liver function at diagnosis improved over time in both groups, but to a greater extent in the viral HCC group. Survival rates increased significantly with time in the viral HCC group, but not in the non‐viral HCC group. Conclusions: The prevalence of non‐viral HCC is increasing. Although the survival of patients with viral HCC improved significantly over the past two decades, there was no improvement in patients with non‐viral HCC. This was presumably due mainly to lower surveillance among patients with non‐viral HCC and failure to diagnose early‐stage HCC. [ABSTRACT FROM AUTHOR]
