Abstract:
Objective To study the half quantitative diagnostic method of the high-risk gastrointestinal stromal tumors (GISTs) with analyzing the characteristic of high-risk and lower risk GISTs with multi-slice spiral CT (MSCT). Methods CT findings of 46 patients with 51 GIST lesions were retrospectively analyzed. The location, size, shape, boundary, growth pattern and other specialties of the tumors in high-risk and lower risk GISTs were studied, moreover statistical analysis was conducted, logistic regression equation was obtained. Results Significant difference was found in tumors' location, size, shape, boundary and distant metastasis between the two types of GISTs. There were obvious correlation between the risk level and tumors' size and boundary which could be used to build the diagnostic equation of high-risk GISTs. Conclusion The equation ln [P/(1-P)]=-2.612X_3+0.371X_5 (X_3:tumors' boundary, X_5:tumors' size) is valuable in the diagnosis of high-risk GISTs.
