ASSESSMENT OF DEPTH OF INVASION (DOI) OF ORAL TONGUE CANCER WITH MRI AT UNIVERSITY MEDICAL CENTER – HO CHI MINH CITY FROM 2022 TO 2023
Main Article Content
Abstract
Objectives: To evaluate the relationships between depth of invasion (DOI) of tongue cancer as measured with preoperative magnetic resonance imaging (MRI) and postoperative histopathologic (Path) specimens. Methods: This cross-sectional study was undertaken on 30 patients with clinical diagnosis of tongue cancer, referred for MRI at University Medical Center – Ho Chi Minh City from December 2022 to August 2023. Results: DOIs on T1WGd MRI were significantly larger than the pathological DOI (p<0.001). DOIs on CE-MRI correlated well with pathological DOI (r=0.825, p<0.001). For oral tongue cancer, the best accuracy is obtained by measuring depth of invasion on axial images. Substantial agreement (k = 0.618) was noted for T staging between clinical and MRI staging assessments. Conclusions: MRI can determine the DOI value accurately and may be valuable for the preoperative staging.
