The levels of liver function tests (LFTs) are often used to assess liver injury and non-liver disease-related mortality. In our study, the relationship between pretreatment serum LFTs and overall survival (OS) was evaluated in esophageal squamous cell carcinoma (ESCC) patients. | Prognostic value of pretreatment serum alanine aminotransferase aspartate aminotransferase ALT AST ratio and gamma glutamyltransferase GGT in patients with esophageal squamous cell carcinoma
