Purpose: Little is known about liver resection (LR) in hepatocellular carcinoma (HCC) patients older than 75 years of age. This study aimed to compare the postoperative and long-term outcomes of hepatectomy in this patient population according to operation period.
Methods: This study included 130 elderly patients who underwent LR for solitary treatment-naive HCC between November 1998 and March 2020. Group 1 included patients who underwent LR before 2016 (n = 68) and group 2 included those who underwent LR during or after 2016 (n = 62).
Results: The proportion of major LR, anatomical LR, and laparoscopic LR (LLR) in group 1 was significantly lower than those in group 2. Also, the median operation time, amount of blood loss, hospitalization length, rates of intraoperative blood transfusion, and complications in group 2 were less than those in group 1. In the subgroup analysis of group 1, high proteins induced by vitamin K absence or antagonist-II, long hospitalization, and LLR were closely associated with mortality. In the subgroup analysis of group 2, however, none of the factors increased mortality. Nevertheless, the presence of tumor grade 3 or 4 and the incidence of microvascular invasion were higher in group 1 than in group 2, and the disease-free survival and overall survival were better in group 2 than in group 1 because of minimized blood loss and quicker recovery period by increased surgical techniques and anatomical approach, and LLR.
Conclusion: LR in elderly HCC patients has been frequently performed recently, and the outcomes have improved significantly compared to the past.
