The diagnosis and treatment plans of GISTs are relied on pathological confirmation, yet the biopsy for unresectable GISTs cannot always provide comprehensive information, which will have an impact on the treatment plan and duration. Radiomics features based on whole tumor analysis have been confirmed as a robust imaging biomarkers with good repeatability in some solid tumors. The present study using the method described above to analyze a group of patients with pathological confirmed GISTs, to determine which radiomics features are useful for stratification and monitoring purpose.
