A prospective study of head and neck cancer patients was started to gather information about topographic and clinical characteristics of head and neck cancer, alcohol and nicotine abuse and the delay in diagnosis.
More than half of the patients consulted our institution with an advanced stage of disease.
As was expected, we found a positive association between the size of the tumour and the clinical stage of the neck.
Concerning nicotine and alcohol abuse, our results support the hypothesis that tobacco smoking is more strongly associated with lesions in sites heavily exposed to inhaled smoke, whereas alcohol consumption has a stronger effect on structures belonging to the'food channel'and reservoir systems.
We found no association between delay and tumour stage at diagnosis, but a statistically significant correlation was found between the delay and the tumour site.
This leads us to conclude that the tumour stage is determined mostly by the biology of the tumour.
