The C-reactive protein to albumin ratio, albumin-bilirubin index and platelet-albumin-bilirubin index have emerged as prognostic scores in hepatocellular carcinoma, although their clinical utility remains unclear, with ongoing investigation in multiple patient populations. This study aims to report survival outcomes and evaluate these indices in a cohort of patients undergoing liver resection for hepatocellular carcinoma in a tertiary Australian centre. This retrospective study reviewed data from the Department of Surgery at Austin Health and electronic health records (Cerner corporation). The impact of pre, intra and post-operative parameters on post-operative complications, overall and recurrence free survival were analyzed. 163 liver resections were performed in 157 patients between 2007 and 2020. Post-operative complications occurred in 58 patients (35.6%), with pre-operative albumin < 36.5 g/L (3.41(1.41-8.29),p = 0.007) and open liver resection (3.93(1.38-11.21),p = 0.011) demonstrating independent predictive significance. 1,3 and 5-year overall survival was 91.0%, 76.7% and 66.9% respectively, with a median survival time of 92.7 months (81.3-103.9). Hepatocellular carcinoma recurred in 95 patients (58.3%) with a median time to recurrence of 27.8 months (15.6-39.9). 1,3 and 5 year recurrence-free survival rates were 94.0%, 73.7% and 55.1% respectively. Pre-operative C-reactive protein-albumin ratio > 0.034 was significantly associated with reduced overall (4.39(1.19-16.16),p = 0.026) and recurrence-free (2.53(1.21-5.30),p = 0.014) survival. C-reactive protein-albumin ratio > 0.034 is a strong predictor of poor prognosis following liver resection for hepatocellular carcinoma. In addition, pre-operative hypoalbuminemia was associated with post-operative complications, and future studies are required to assess the potential benefits of albumin replacement in reducing post-surgical morbidity. |
