ABSTRACT
We have carried out a survey on larynx cancer for the Cartagena region between the years 1972 and 1984 out of a population that varies from 210,944 to 250,233 inhabitants and a total number of 207 cases with histopathology control. The average incident valuation per every 100,000 inhabitants is 6.9 for the total population and 13.74 for males. An important fact is the amount of supraglottical carcinomas which have been discovered, meaning 51.08%; more common in males under 60, which has a very close connection with the consumption of black tobacco. The glottical carcinoma represents 46.80% of the cases, more common in males over 60 not related to a smoking habit. The high risk population is formed by males between 55 and 65 who are heavy smokers and drinkers and do manual labour.

We have carried out a research into the clinicopathological characteristics of the cancer of larynx between 1972 and 1984 in the area of Cartagena, with a populations that oscillated between 210,944 and 250,233 inhabitants, and over a number of 207 cases. We observe that the symptom to which the patients attach most importance and the reason why they most often consult is dysphonia or voice-alteration, and that its clinical development average time until diagnosis is of 6.08 months. It is to be pointed out the proportion of supraglottic carcinomas which at the moment of diagnosis usually show a T3 or a T4 stage and palpable adenopathies in a third of the patients. On the contrary, glottic carcinomas are usually T1 lesions and without satellite adenopathies. With regard to the histologic type, the great majority of cases belong to epidermoid carcinomas, followed at a great distance by warty carcinomas and finally by pseudosarcomas.
