Since the T classification of laryngeal tumours involves assessment of vocal cord fixation, does it mean that pT is not possible without such information given by the clinician?
For pathological classification concerning impaired mobility or fixation of vocal cords, the information from the clinical T is used for the pathologic T. This is in accordance with TNM rule No. 2, pathological classification “is based on the evidence acquired before treatment, supplemented or modified by the additional evidence acquired from surgery and from pathological examination”.
