Gastrointestinal Stromal Tumour Management at the Bouake University Hospital

Gastric GISTs are rare tumours that are often detected late. The aim of this study was to describe the different treatment modalities for gastric GISTs at Bouake University Hospital. It was retrospective study of 17 patients with gastric GIST between January 2013 and December 2023. GISTs accounted for 4.2% of all gastric tumours. The main reason for consultation was an abdominal mass. The average duration of progression was 10.9 months ± 2.1 months. FOGD, performed in 7 patients, suspected GIST in only one case. Abdominal CT scan, performed in 15 patients, was suggestive of GIST in 8 cases. The tumour was located in the antrum in 11 cases. There was extension to neighbouring organs in 5 cases. The tumours were classified as stage III in 9 cases. Immunohistochemistry confirmed the diagnosis of GIST with expression of C-KIT (CD117) antibodies in all cases. GIST is most often diagnosed at the stage of a large abdominal mass. Immunohistochemistry, which allows for diagnostic confirmation, is not accessible to most patients.
