Gene expression analysis and the risk of relapse in favorable histology Wilms' tumor.

Introduction And Objectives: Wilms' tumor (WT) relapse occurs in 15% of patients. We aim to investigate the association between the expression of several genetic markers and WT relapse risk.

Materials And Methods: The study included 51 children treated for WT at a tertiary center between 2001 and 2019: 23 patients had disease relapse (group A) and 28 remained relapse-free after at least 2 years of follow-up (group B).
