Correlation of ultrasonic characteristics, clinicopathological features, and biological risk classification in gastric gastrointestinal stromal tumors and construction of a preoperative prediction model: a feasibility study

Key Points

• The model demonstrates excellent predictive performance for gastric GIST risk classification, enhancing clinical assessments.
• Ultrasound-based tumor size and echogenicity operate as strong indicators for preoperative evaluation in gastric GISTs.
• Using ultrasound characteristics, the study constructs a prediction model to assess biological risk classification effectively.
• Identifying robust preoperative indicators supports the feasibility of the model for real-world clinical applications.
