Objectives

Narrative objectives1

This multicenter study aims to evaluate the short- and long-term outcomes of laparoscopic and open surgery in patients aged 80 years or older with newly diagnosed hepatocellular carcinoma. Regarding prognosis, the study will investigate not only cancer recurrence and treatment outcomes for recurrent hepatocellular carcinoma, but also details of other causes of death, which are more common in elderly patients.
