Gastrointestinal stromal tumors (GISTs) are rare soft tissue tumors. Despite their rarity, these tumors are the most common gastrointestinal (GI) mesenchymal tumors. They can involve various parts of the gastrointestinal tract. GISTs growth can be intramural, intraluminal or exophytic. Symptoms are usually related to GI bleeding and to adjacent organ compression by the tumor. Endoscopy can sugg...
AIMS AND BACKGROUND Even though the standard treatment of patients affected by gastrointestinal stromal tumors has been well defined by clinical trials and clinical guidelines, in practice it may be different from those proposed in the literature. This paper reports and comments on a critical picture of the management of patients with gastrointestinal stromal tumors who received at least one tr...
BACKGROUND: Gastrointestinal stromal tumors (GIST) constitute a large majority of mesenchymal tumors of the gastrointestinal (GI) tract, which express the c-kit proto-oncogene protein, a cell membrane receptor with tyrosine kinase activity. GI stromal tumors of the stomach are usually associated with bleeding, abdominal pain or a palpable mass. CASE PRESENTATION: A 75-year-old male presented wi...
Ung thư biểu mô tuyến (adenocarcinomas) và u đệm đường tiêu hóa (GIST- gastrointestinal stromal tumors) là hai loại riêng biệt có nguồn gốc từ các tế bào khác nhau. Số trường hợp sự cùng phát triển của cả 2 này ở dạ dày hiếm gặp. Chúng tôi thông báo tồn tại ung GIST dày. Bệnh nhân nam, 61 tuổi, nội soi vùng hang vị loét sùi 2x3cm dưới niêm mạc kính 3cm, bệnh được phẫu thuật cắt đoạn cực dưới, m...
Gastrointestinal stromal tumors (GISTs) originate from interstitial Cajal cells on intestinal pacemaker cells that arise from the muscularis propria of the gastrointestinal tract wall. GISTs are characterized by the expression of c-KIT protein (CD 117, stem cell factor receptor) and are the most common mesenchymal tumors of the digestive tract. That protein, which is detected via immunohistoche...
Gastrointestinal (GI) mesenchymal tumors other than gastrointestinal stromal tumor (GIST) are rare neoplasms, but they often enter the differential diagnosis of more common GI lesions. Some of these mesenchymal tumors in the GI tract have well understood molecular pathologic aspects, including desmoid tumors, inflammatory myofibroblastic tumor (IMT), clear cell sarcoma (CCS), inflammatory fibro...
