Prognostic value of ferroptosis‐related genes in patients with lung adenocarcinoma
Abstract Background The prevalence of lung adenocarcinomas (LUADs) has dramatically increased in recent decades. Ferroptosis is a process of iron‐dependent regulatory cell death. It is still unclear whether the expression of ferroptosis‐related genes (FRGs) is involved in the pathogenesis and surviv...
