RESUMEN
Antecedentes Los tumores del estroma gastrointestinal (TEG) son los tumores mesenquimales más comunes del tracto gastrointestinal (TGI), se considera que surgen de las células de Cajal, ocurren principalmente en adultos mayores (60-65 años) y se localizan en estómago (50%-70%), intestino delgado (25%-35%), colon-recto (5%-10%) y esófago (<5%). La mayoría se presenta de manera esporádica y hasta el 70% son clínicamente sintomáticos. El diagnóstico definitivo se realiza en el estudio anatomopatológico. El pronóstico de estos tumores se determina por el tamaño, recuento mitótico y localización del tumor, clasificandose riesgo muy bajo, riesgo bajo, riesgo intermedio y riesgo alto. La cirugía es la opción terapéutica principal...
ABSTRACT

Background:

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract (GI), areconsidered to arise from the Cajal cells. Theyoccur mainly in older adults, 60-65 years. Theypresent in the stomach (50%-70%), small intestine (25%-35%), colon and rectum (5%-10%)and esophagus (<5%). Most GISTs are sporadicand are clinically symptomatic. The definitivediagnosis is made through anatomic pathology study. To determine the prognosis of this type of tumors we use the size, mitotic count and location of the tumor, classified them in very low risk, low risk, intermediate risk and high risk. Surgery is the main treatment...
