Impairment of perioperative activities of daily living is associated with poor prognosis following hepatectomy for hepatocellular carcinoma.

ABSTRACT

BACKGROUND: The number of cancer patients with impairment of activities of daily living (ADLs) has increased. This study aimed to examine associations of perioperative Barthel index score, a validated measure of ADLs, with survival outcomes following hepatectomy for hepatocellular carcinoma (HCC). METHODS: We analyzed data of 492 consecutive patients who underwent hepatectomy for HCC between 2010 and 2018. Pre- and postoperative ADLs were assessed using the Barthel index (range, 0-100; higher scores indicate greater independence). Preoperative Barthel index score ≤85 or postoperative Barthel index score ≤85 was defined as impairment of perioperative ADLs. Cox proportional hazards regression was used to calculate hazard ratios (HRs) after adjusting for potential confounders. RESULTS: Among the 492 patients, 26 (5.2%) had a preoperative Barthel index score ≤85 and 95 (19%) had a postoperative Barthel index score ≤85. Impairment of perioperative ADLs was independently associated with shorter overall survival (multivariable HR 1.75, 95% confidence interval [CI] 1.06-2.81, p = 0.028). The association of impairment of perioperative ADLs with recurrence-free survival was not statistically significant. CONCLUSION: Impairment of perioperative ADLs is associated with poor prognosis following hepatectomy for HCC. Maintenance and improvement of perioperative ADLs would be important to provide favorable long-term outcomes in patients with HCC.
