High STAT4 Expression is a Better Prognostic Indicator in Patients with Hepatocellular Carcinoma After Hepatectomy

Background Signal transducer and activator of transcription 4 (STAT4) mediates the intracellular effects of interleukin-12, leading to the production of interferon gamma (IFN-γ) and natural killer cells cytotoxicity. However, the clinical significance of STAT4 expression in patients with hepatocellular carcinoma (HCC) remains virtually unknown.
