Implication

Observational study reveals cholestasis and glutamine synthetase expression identify beta-catenin-mutated hepatocellular carcinoma, indicating distinct metabolic alterations in liver tumors.

Key Points

To correlate glutamine synthetase immunostaining and beta-catenin mutations with clinicopathological characteristics in hepatocellular carcinoma.
Evaluated the diagnostic sensitivity and specificity of glutamine synthetase immunostaining and beta-catenin immunostaining against sequence analysis.
Profiled clinicopathological characteristics, including cell differentiation and bile accumulation, across 190 hepatocellular carcinoma cases using glutamine synthetase as a biomarker.
Glutamine synthetase immunostaining achieved 90% sensitivity and 98% specificity for identifying beta-catenin mutations, outperforming beta-catenin immunostaining (63% sensitivity, 98% specificity).
Wnt/beta-catenin pathway activation occurred in 68 of 190 tumors (36%) and significantly correlated with a well-differentiated microtrabeculo-acinar pattern, low-grade cellular atypia, and cholestasis.
