CELF4 (rs1786814) gene polymorphism and speckle-tracking Echocardiography for cardiovascular complications in childhood cancer survivors.

Background: Despite a well-known dose-dependent association between the risk of cardiac dysfunction and anthracycline, the risk of cardiac dysfunction for any given anthracycline dose varies between patients. So, we assessed CELF4 (rs1786814) gene polymorphism on anthracycline-related cardiotoxicity in childhood cancer survivors (CCS).

Methods: This comparative cross-sectional study included 53 CCS who had regular follow-up visits at the Pediatric Oncology Unit, Menoufia University Hospital.
