title: Gastrointestinal malignancies in infancy, childhood, and adolescence.
abstract: Gastrointestinal and hepatobiliary malignancies in the pediatric age group are rare tumors and are usually treated with frustratingly poor results because of late diagnosis. Current efforts to improve treatment are directed at earlier diagnosis of these tumors in combination with aggressive surgery and adjuvant therapy.
