Oral tongue cancer in public hospitals in Madrid, Spain (1990-2008).
BACKGROUND
The cancer which appears in the mobile portion of the tongue is the most common neoplasm of the oral cavity. The objective of this study was to analyse oral tongue cancer epidemiology in a population of 610 patients diagnosed between 1990 and 2008 and detailed in the Tumour Registry of the Madrid region.


METHODS
A retrospective analysis based on the following variables provided in the Tumour Registry was achieved: age, gender, histology, stage, location, treatment. Descriptive and analytic statistics with these variables, using Pearson's Chi-square test to study the relationship between the qualitative variables.


RESULTS
Patients' mean age was 61.53±13.95 years, with a gender ratio of 2.09:1 (413 males vs 197 females). The lesion was mainly localized in the lateral border of tongue, with other sites (dorsal face, ventral face, lingual tonsil, contiguous sites, tongue NOS) represented at lower rates. Squamous cell carcinomas (94.9%) far outweighted other histologies (salivary gland tumours, soft tissue tumours, haematolymphoid tumours). 59% of the cases appeared in localized stages, versus 35.2% in regional and 4.8% in distant stages. Surgery was the most frequently used treatment, followed by surgery in combination with radiotherapy.


CONCLUSIONS
Oral tongue cancer is a disease of the elderly, with a male predominance. It mainly appears in its lateral border, localized squamous cell carcinomas representing the great majority of lingual neoplasms.
