Embryonal Tumors of Infancy & Childhood: South Egypt Cancer Institute Experience

Background: Embryonal tumors arise from cells that are normally present in the developing embryo and originate in developing tissues and organ systems. These tumors occur almost exclusively in children, and are usually diagnosed in children before age 5 years. The group is heterogeneous and includes relatively common pediatric tumors as well as rare tumors. Three common types of embryonal tumors in children are neuroblastoma, Wilms tumor (WT), and retinoblastoma. Other embryonal tumors, include medulloblastoma and rhabdomyosarcoma. Patients \& Methods: From January 2001 to December 2015, retrieval \& analysis of the medical records of pediatric patients with embryonal tumors will be made at the pediatric oncology department, South Egypt Cancer Institute which represents the largest referral center in Upper Egypt. These data will be categorized according to demographic characteristics, clinico-pathologic features, treatment modalities received, and outcomes of treatments in these patients.
