Abstract
Purpose: To evaluate the concordance between computed tomography (CT) findings and surgical and pathological results in gastrointestinal stromal tumors (GISTs) regarding tumor location and invasiveness. Additionally, to determine the relationship between CT-based tumor shape quantification and the malignant risk based on the modified NIH criteria.
Methods: From January 2021 to January 2024, we conducted a retrospective study on 51 patients with GISTs. The patients underwent CT imaging and surgery at Ho Chi Minh City Oncology Hospital.
Results: GISTs were most common in the stomach and in patients over 50 years of age. CT findings correlated with surgical pathology in tumor location and invasiveness. There was a statistically significant difference between the long-axis diameter, short-axis diameter, small angle, and the large-to-small angle ratio of the tumors and their NCAT, which was classified into three groups: very low–low risk, intermediate risk, and high risk. The long-axis diameter, short-axis diameter, and large-to-small angle ratio were able to differentiate high NCAT tumors from the remaining groups.
Conclusion: CT is a highly valuable tool for diagnosing the location, and invasiveness of GISTs. The short-axis diameter, long-axis diameter, and the large-to-small angle ratio can differentiate tumors with high NCAT from the other groups.
