[TNM system: presentation of graphic classification of T laryngeal cancer]

Using the most recent TNM revision as a basic framework to build upon, the Authors set up a graphic representation of the larynx on the basis of data gathered using clinical-instrumental examination. This graph, which allows automatic extrapolation of the degree of T, represents various sites and subsites of the larynx (including the pre-epiglottic area, the retro-cricoid area and the piriform sinus) which are divided by different coloured lines. This simple graphic representation of cancerous tumours, whose various colours indicate tumor extension in depth (data had with CT and RM), allows for automatic T classification of larynx cancer on the basis of T extension as well as on that of the degree of vocal cord impairment. Particularly useful for students in memorizing TNM classification, this graph, furthermore, groves to be a means of facilitating under standing the disease as well as opinion exchange among members of the medical staff. As furthermore proves of utmost value in patient management in that it may be fed into computerized management programmes containing individual patient's records thereby permitting a more rapid classification of the tumor. Moreover, the data easily stored in the programme are readily accessible for eventual statistical elaboration. The Authors conclude with a proposal of the eventual use of a similar graph of other sites in the body which may be adapted in the event of future TNM revisions.
