ARTICLE HIGHLIGHTS
Research background
Clinical decision-making depends on preoperative assessment of the likelihood of malignancy and prognosis of these gastrointestinal stromal tumors (GISTs). Correlation between computed tomography (CT) image features of GIST and pathological risk grade has been previously reported in several publications. However, only a few studies have attempted to correlate CT features with histologic grading or prediction of gastric malignancy.
Research motivation
The research is to explore the multi-slice CT imaging features for predicting risk stratification in patients with primary gastric GISTs, and to give clinicians a straightforward yet useful tool to use in choosing the best surgical approach and preoperative neoadjuvant therapy.
Research objectives
The purpose of this study was to identify the CT imaging characteristics for predicting risk stratifications in patients with primary gastric GISTs.
Research methods
This retrospective analysis of clinicopathological and CT imaging data for 147 patients with gastric GISTs. The association between malignant potential and CT features was analyzed using univariate analysis and multivariate logistic regression analysis, receiver operating curve was used to evaluate the predictive value of tumor size, and the multinomial logistic regression model for risk classification.
Research results
Tumor size, tumor contours, lesion growth patterns, ulceration, cystic degeneration or necrosis, lymphadenopathy, and contrast enhancement patterns, were associated with the risk stratification; tumor size, contours and growth pattern were independent predictors for risk stratification of gastric GISTs.
Research conclusions
CT features, including tumor size, growth patterns, and lesion contours, were predictors of malignant potential for primary gastric GISTs.
Research perspectives
The CT characteristics could offer clinicians a straightforward yet useful tool for making smart clinical judgments.
