Small intestine GIST associated with better prognosis in younger patients

Gastrointestinal stromal tumors (GIST) are tumors that arise is the wall of the digestive tract, and most often occur in the stomach or small intestine. Though more common in later in life, GISTs can occur in adolescents and young adults (AYA) under 40 years old as well. Researchers report findings from the first population-based analysis of AYA patients with GIST.
