Gastrointestinal stromal tumors.

In the last 3 years 9 patients with gastrointestinal stromal tumors (GIST) underwent surgery at our department. All cases were with very atypical process. From these patients 3 interesting cases are described in more details. A 75-years-old woman with gastroscopically verified endoluminal tumour in the proximal third of stomach, 6x7 cm, 76-years-old man with a large endoluminal tumour in D2-D3 part of the duodenum, 4x4 cm, and 62-years-old man with verified extraluminal tumour by CT examination in the middle part of stomach. In all cases, gastrointestinal stromal tumour was histologically confirmed. Work is well photo-documented pre-surgically with endoscopic and CT-findings and during surgery: individual steps during the removal of these tumours. In assessment of the size and number of mitoses, tumours belonged to a group with highly malignant potential. Patients are regularly checked in 3-months intervals and also examination by positron emission tomography was performed--it seems to have the best demonstrability of possible relapse. All three patients live and are subjectively and objectively without significant problems (Tab. 5, Fig. 5, Ref. 7). Full Text (Free, PDF) www.bmj.sk.
