These tumors typically express the phenotype CD117/KIT + and CD34 +. To evaluate epidemiologic, clinical, pathologic, therapeutic, characteristics and evaluative pattern of gastrointestinal tumor treated in our surgical department. We collected 24 cases of GIST (confirmed by the positivity of CD 117 and/or CD 33) treated between 1997 and 2010 in the department of surgery B of Charles Nicolle's Hospital.

We calculated the survival rate and identified prognostic predictive factors of survival. Our retrospective study interested, during 13 years, 24 patients presenting GIST with a median age of 66 years and a sex ratio of 0.8. The median time for diagnosis was two months (3 days to 24 months). Abdominal pain, gastrointestinal bleeding and vomiting were the most common symptoms.
