title: [Malignant tumours of the pharynx in the years 1992-2001].
abstract: All cases of malignant tumours of the pharynx (excluding tumours of the tongue) were analyzed based on the retrospective data from the 5 clinical centers in Poland from the years 1992-2001. A considerable--over 50% increase in morbidity was found out regarding particularly tumours of the oropharynx. In the analyzed material there is a predominance of males (3:1) and the peak of morbidity significantly falls. The subjects with advanced tumours of the pharynx made 26% of the studied group. The most common histopathological diagnosis was squamous cell carcinoma and the most common site--the oropharynx, in particularly the tonsil. The data the center in Katowice, where tumours of the hypopharynx have been predominant in the last few years, may point a similar tendency in the other centers in the future.
