Gastric GIST Clinical Trial
Official title:
Clinicopathological Characteristics and Prognostic Factors of Gastrointestinal Stromal Tumors Located in the Stomach in Tunisian Patients
Gastrointestinal stromal tumor (GIST) is the most common non-epithelial mesenchymal tumor of the gastrointestinal tract. Surgical treatment is the only curative therapy for primary localized GIST. This study aimed to identify the clinicopathological characteristics of gastric GISTs and to study the predictive factors for recurrence in Tunisian patients.
The prognosis of gastric GIST depends on various tumor factors with the most important being
the mitotic index and tumor necrosis. Imatinib therapy has revolutionized the treatment of
advanced GIST.
They have been the subject of much controversy in terms of their histogenesis,
classification, treatment and prognosis. GISTs are histologically similar to smooth muscle
and nerve tumors such as leiomyomas, leiomyosarcomas or schwannomas. Currently they are well
characterized with the recent discovery of the C-KIT gene mutation and the expression by
tumor cells of the C-KIT protein.
Moreover, the discovery of this receptor is at the origin of the introduction of a "targeted
therapy": an anti-tyrosine kinase molecule having revolutionized the therapeutic management
of these tumors. However, the standard curative treatment of GIST remains complete surgical
resection with negative margin from the tumor.
