Gastrointestinal tumors in children

Abstract

Gastrointestinal tumors in children and adolescents are very rare. They differ from the adult gastrointestinal cancer in different histological types of tumors, their incidence, etiology and clinical symptoms. Experience with their diagnosis and treatment in children are limited. The fundamental difference from the adult gastrointestinal cancer is absence of pediatric clinical trials. An exception is the treatment of pediatric abdominal non-Hodgkin lymphoma. Cooperation and experience of adults oncology are therefore necessary.
