[Registry of cancers of the upper aero-digestive tract in departments of the North and Pas-de-Calais. Report for the year 1984].

The authors give the results of the head and neck carcinoma registry in the Northern France at the end of the first registration year. This registration was easily carried out with a pathologic diagnosis known in 99% cases. The carcinoma incidence is rather high in this French country: 1 636 new cases, i.e. an incidence about 79.5/100 000 males. The most frequent are buccopharyngeal carcinoma. It seems to exist some differences between different Northern districts which shows the necessity of epidemiologic studies and of such a registry.
