Diagrammatic recording of head and neck tumours.

The increasing demands of clinical audit have resulted in the need for accurate data collection. The use of tumour maps allows standardization of the records of patients with head and neck cancer, which facilitates collation of data in multicentre studies and makes interdepartmental comparisons more meaningful. The aim of this study was to develop an improved standard set of tumour maps for recording the stage of head and neck tumours. A review of the existing tumour diagrams was performed to identify those anatomical areas that are not adequately represented or where ambiguity exists. The areas where improvements could be made were identified as: (1). the anterior commissure of the larynx; (2). axial and sagittal views of the larynx; (3). the pyriform fossa and cervical oesophagus; (4). the oropharynx and vallecula; (5). the nasal cavity and paranasal sinuses; and (6). cervical nodal involvement. A new set of tumour maps is presented in an attempt to correct some of the limitations of the existing diagrams.
