[Experience in staging malignant tumors of the orofacial area].

The paper reports the authors experience at the Regina Elena Institute for the Study and Treatment of Tumours in Rome during the period 1987-1989 concerning the setting up of a register for primary malignant tumours of the head and neck. This experience has allowed various parameters to be assessed from the initial diagnosis through the subsequent diagnostic and therapeutic procedures [correction of iter]. The stage of disease was assessed in 134 patients using a TNM system proposed by UICC for tumours located in the oral cavity, oro- and hypo-pharynx and maxillary sinuses. At the end of the period a complete definition was made of some typical aspects of the disease in question: firstly, the high incidence of patients with advanced stages of disease found at the first diagnosis, and secondly, the significant delay in confirming the diagnosis of the tumour in spite of the ease with which the area may be explored. In conclusion, the authors comment on current systems of TNM classification, underlining the need for a more correct interpretation and assessment of findings related to neoplastic orofacial pathologies.
