Core Tip: Gastric stromal tumors (GSTs) are all malignant, but generally, the smaller the diameter, the more likely the tumor is inert. However, GSTs smaller than 2 cm in diameter are also at risk of growing and becoming more malignant. Endoscopic treatment of GSTs smaller than 5 cm in diameter is comparable to surgical treatment. Early endoscopic resection is safe and effective when there are high risk factors for GSTs smaller than 2 cm in diameter or the patients cannot be followed regularly, and different endoscopic treatment methods can be selected according to the tumor site and depth.
