The prognosis of elderly patients with hepatocellular carcinoma: A multi-center 19-year experience in Japan

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.

Automated summary

This retrospective study compared the survival of elderly and non-elderly patients with hepatocellular carcinoma (HCC) and found that despite improvement in liver function, survival in elderly patients did not improve. The study suggests that curative treatments should be evaluated and conducted when appropriate for each elderly patient.
