Abstract:
The incidence of gastrointestinal stromal tumor(GIST) is 1-2 per 100 000. Micro GIST with a size less than 1 cm are found in 3%-35% elderly population. These small-size GIST are usually located in the middle or upper stomach, with gain-function KIT or PDGFRA mutation. In this review, the clinicopathological features and management of these small-size GISTs are discussed.
Insights
Micro gastrointestinal stromal tumors (GISTs), smaller than 1 cm, are common in the elderly. This review covers their features and management, focusing on KIT or PDGFRA mutations.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Gastrointestinal stromal tumors (GISTs) affect 1-2 individuals per 100,000 people.
- Micro GISTs (<1 cm) are incidentally found in 3%-35% of the elderly population, often in the upper/middle stomach.
Discussion:
- This review focuses on the clinicopathological characteristics of small GISTs.
- Management strategies for these micro GISTs are critically examined.
Key Insights:
- Micro GISTs frequently harbor gain-function mutations in KIT or PDGFRA genes.
- Understanding these mutations is key to managing small GISTs.
Outlook:
- Further research into the specific behavior and optimal surveillance or treatment for micro GISTs is warranted.
- Personalized management approaches based on mutational status may evolve.
