The prognostic value and non-invasive predictors of splenomegaly in cirrhotic patients with hepatocellular carcinoma following curative resection.

BACKGROUND
The prognostic value and non-invasive predictors of splenomegaly in cirrhotic patients with hepatocellular carcinoma (HCC) after curative resection remain unknown.


OBJECTIVES
To investigate the prognostic value and non-invasive predictors of splenomegaly in cirrhotic patients with HCC after curative resection.


MATERIAL AND METHODS
The medical records of 78 patients with HCC and liver cirrhosis who underwent curative resection were retrospectively reviewed. The influence of spleen size, measured with clinically routine ultrasonography (USG), on overall and disease-free survival was evaluated using univariate and multivariate analyses. The efficiency of some frequently used blood-derived liver function parameters and non-invasive fibrosis markers to predict splenomegaly was also assessed.


RESULTS
It was shown that tumor size >5 cm, the presence of microvascular invasion, tumor-node metastasis (TNM) stage III-IVA of the tumor, spleen size >11.45 cm, and age ≤52 years were associated with poor overall survival and/or disease-free survival in univariate analyses (all p < 0.05). In multivariate analyses, spleen size was identified as an independent predictor for both overall and disease-free survival (p < 0.001 and p = 0.012, respectively). On the other hand, platelet count, aspartate aminotransferase (AST) to platelet ratio index (APRI) and Fibrosis-4 index (FIB-4) scores were significantly different between small and large spleen groups (p = 0.026, 0.003 and 0.003, respectively), while statistical differences for albumin, alanine aminotransferase (ALT), AST, total bilirubin, AST to ALT ratio (AAR), and age-platelet index (API) were not found. Using receiver operating characteristic (ROC) curves, high powers of platelet count, APRI and FIB-4 in splenomegaly prediction were confirmed.


CONCLUSIONS
Splenomegaly, which can be predicted by some non-invasive variables, serves as a strong determinant for postresectional prognoses of cirrhotic patients with HCC.
