Core Tip

Core Tip: The use of endoscopic surgery in gastrointestinal stromal tumors (GISTs) between 2 and 5 cm remains controversial considering the potential risk of metastasis and recurrence. Also, surgeons are facing great difficulties and challenges in assessing the malignant potential of 2-5 cm gastric GISTs. This study aimed to develop and evaluate computerized tomography-based radiomics for predicting the malignant potential of primary 2-5 cm gastric GISTs.
