Approche epidemiologique des cancers du cavum au Maroc

ABSTRACT

412 cases of nasopharyngeal carcinomas were seen in Bergonie's Center of Casablanca [the only center in function], between 04/01/80 to 08/31/83. It represents 4,76% of all malignant tumors diagnosed in the same period. This percentage seems to us very low, but, the majority of these tumors are not diagnosed, outside the big towns. We just try to study the epidemiological aspect of our series; there is a predominance of males [sex-ratio is 2,25], middle-age is 43 years with a big proportion of young people [24,6% are less than 30 years old]. The high "incidence" is observed in the north of the country. Advanced tumors are more common, 15% are with no possibility of treatment, 32.5% are T4, and 70% have had cervical nodes. 90% of our cancer are U.C.N.T. The results of the immunologic study do not exclude a viral [E.B.V] contribution. Prospective epidemiologic studies are indispensable to know the exact profile of this cancer in our country
