Background/Aim:
The prognostic outcome of the controlling nutritional status (CONUT) score in patients with colorectal liver metastases (CRLM) who underwent hepatectomy has not been investigated. The aim of this study was to investigate the prognostic value of preoperative CONUT score and other systemic inflammation-related biomarkers in patients who underwent hepatectomy for CRLM.
Patients And Methods:
The subjects included 145 patients with CRLM who underwent hepatectomy and retrospectively investigated the association of preoperative CONUT score with disease-free survival (DFS), surgical failure-free survival (SFS), and overall survival (OS) using univariate and multivariate analyses.
Results:
In this study, the cut-off of the CONUT score was 4. In the univariate analysis, the high CONUT score was associated with worse SFS and OS (p=0.01, 0.01). The multivariate analysis showed significant and independent predictors of OS were lymph node metastases (p=0.03) and a high CONUT score (p=0.04). In patients with a high CONUT score, postoperative complications due to infections were significantly more than in those with a low CONUT score (27% vs. 9%, p=0.04).
Conclusion:
The CONUT score can be useful for predicting not only short-term but also long-term outcomes in patients with CRLM after hepatectomy.
