Abstract
BACKGROUND: With the advent of AJCC 8th edition, Depth of Invasion (DOI) is given significance for T staging of oral tongue cancers. AIM and OBJECTIVE: To compare the accuracy of depth of invasion in tongue carcinoma measured by MRI and intraoral USG and correlating it with histopathological examination as gold standard. MATERIALS AND METHODS: A comparative cross sectional study designed to compare the value of depth of invasion measured on T2 weighted MR images in Siemens 1.5T Avanto and intraoral USG using high frequency transducer ( 3 – 16 Mhz) in Samsung HS 40. The parameters assessed were depth of invasion, tumour thickness and pre operative T staging was given based on DOI value in accordance with the AJCC 8th edition. Study population was 76 and study period was from December 2020 to November 2021. All cases with stage T4 were excluded from our study. RESULTS: The statistical analyses were performed using SPSS and a ‘p’ value of <0.05 was considered significant. Bland Altman plots were utilised and for USG, P value in regression is 0.001 which is less than significant p value of 0.05 which means that there is no significant difference. For MRI, P value in regression is 0.158 which is more than significant p value of 0.05 at 95% confident interval which means that there is significant difference. CONCLUSION: Hence DOI measured by intraoral USG is correlating well with the post surgical HPE DOI and can be used as an effective imaging tool for staging.
