ERICH5 and esophageal squamous cell carcinoma: ESCC tumor tissues exhibited markedly decreased AMN and ERICH5 expression but increased HRG compared to normal controls.<h4>Conclusion</h4>This study identified prognostic signature genes associated with CRT and PS in ESCC and constructed a risk model that may predict patient survival, which could provide valuable insights for future research on ESCC diagnosis and treatment.
