ROLE OF PERCUTANEOUS ULTRASOUND IN cT1-3 BUCCAL MUCOSAL CARCINOMAS

Le résumé fourni par la source

BACKGROUNDThe staging of buccal carcinomas has been expanded in the AJCC 8 th edition to include depth.We analysed the role of percutaneous ultrasound in the evaluation of cT1-3 buccal carcinomas.Most buccal carcinomas are commonly assessed by CT scans where the tumour may be isodense to the adjacent muscles making accurate assessment of tumour thickness difficult.There have been a few studies investigating the role of intraoral ultrasound in the assessment of thickness of oral cancers, but most of these had larger number of tongue tumours as compared to buccal lesions.We wanted to assess the correlation of thickness of buccal mucosal carcinoma by ultrasound and histopathology and its impact on the staging as per AJCC 8 th edition.
