BACKGROUND AND PURPOSE: Extrinsic @entity11090 in @entity1697 upstages the @entity5 to a @entity6461 . Despite this American Joint Committee on @entity5 staging criterion, no studies have investigated the accuracy or prognostic importance of radiologic extrinsic @entity11090 , the feasibility of standardizing extrinsic @entity11090 reporting, or the degree of agreement across different disciplines: radiology, surgery, and pathology. The purpose of this study was to assess the agreement among radiology, surgery, and pathology for extrinsic @entity11090 and to determine the imaging features most predictive of extrinsic @entity11090 with surgical/pathologic confirmation. MATERIALS AND METHODS: Thirty-three @entity1 with untreated primary @entity1697 were included. Two head and neck radiologists, 3 otolaryngologists, and 1 pathologist prospectively evaluated extrinsic @entity11090 . RESULTS: Fourteen of 33 @entity1 had radiologic extrinsic @entity11090 ; however, only 8 extrinsic tongue muscle invasions were confirmed intraoperatively. Pathologists were unable to determine extrinsic @entity11090 in post- @entity406 -fixed samples. Radiologic extrinsic @entity11090 had 100% sensitivity, 76% specificity, 57% positive predictive value, and 100% negative predictive value with concurrent surgical-pathologic evaluation of extrinsic @entity11090 as the criterion standard. On further evaluation, the imaging characteristic most consistent with surgical-pathologic evaluation positive for extrinsic @entity11090 was masslike enhancement. CONCLUSIONS: Evaluation of extrinsic @entity11090 is a subjective finding for all 3 disciplines. For radiology, masslike enhancement of extrinsic @entity11090 most consistently corresponded to concurrent surgery/pathology evaluation positive for extrinsic @entity11090 . Intraoperative surgical and pathologic evaluation should be encouraged to verify radiologic extrinsic @entity11090 to minimize unnecessary upstaging. Because this process is not routine, imaging can add value by identifying those cases most suspicious for extrinsic @entity11090 , thereby prompting this more detailed evaluation by surgeons and pathologists.
