Malignant tumors in Cuban children. Fourth triennial 1973-1975 of the national cancer registry.
The incidence of malignant tumors in children is not as high as that in adults, though in Cuba and other countries they are the most frequent causes of death in this age group. Data of the fourth triennial of the Registro Nacional del Cáncer (Cuban Cancer Registry) in the period 1973-1975 are presented. In the age group 0-14 years, 1038 new cases were diagnosed and registered; this figure represented 2.5% of the total of tumors in the period studied; the mean annual rate was 11.3% per 100 000 population. Male patients were more frequently affected. Morbidity decreased in 0-4 year group and increased in 10-14 year group. As in the first, second and third triennials, malignant diseases as leukemia, lymphoma and tumors of the nervous system prevailed among children: these accounted for a little more than 2/3 of the total of tumors followed by tumors of the kidney and eye.
