[Current remarks for use of the TNM classification on head and neck (author's transl)]

The revised rules of classifications of UICC (1973) for the field trail 1974-1977 will be published (nasopharynx, oropharynx, hypoparynx; larynx; oral cavity); own recommendations for the organs inner nose and sinuses, salivary glands and skin (head and neck) are added. In the enlarged TMN-key identification number, date of diagnosis, number of localisation, symbol c (certainty) and number of histology are mainly taken into consideration; stage and staging remain secondary. Checklists and proformas prepared for use in a computer simplify the documentation.
