ABSTRACT
Tumors of the nervous system are the third most common malignant disease in Cuban children, after leukemia and lymphoma. In 138 patients with the diagnosis of brain tumor results of treatment by surgery and radiation were studied. The survival rate at 1, 3 and 5 years was 50, 40 and 37.6%. The best results were achieved in astrocytomas, mid grain and brain stem tumors and oligodendrogliomas.

Treatment results in 391 patients with oral carcinoma after radiation therapy are reported. In the total series 5- and 10-year actuarial survival were 30.8 and 25.2 per cent, respectively. After irradiation alone the corresponding figures were 21.5 and 18.5 per cent, after combined radiologic and surgical treatment 33.3 and 28.7 per cent, and after interstitial radium therapy 56.1 and 43.8 per cent, respectively. These differences were mainly an expression of selection factors. Tumor doses above 60 Gy gave a higher survival than lower doses. The presence of neck node metastases was prognostically unfavourable.

Survival data in 1 106 patients with cervical carcinoma treated between 1967 and 1972 are presented. Survival figures decrease when doubtful or evident activity of the tumor persists at the end of the irradiation.

The types and frequency of complications in 2248 patients irradiated for carcinoma of the cervix using different techniques are reported. Proctitis was the most frequent complication. Severe complications, such as fistulas, ureteral stenosis with hydronephrosis, enterocolitis, sigmoiditis, intestinal obstruction and skin necrosis occurred in 81 patients (3.6%). Only 36 patients (1.6%) developed fistulas.

Data on the survival of 2 248 patients with cervical carcinoma, treated between1966 and 1972 at 3 oncologic centers in Cuba, are presented. Intracavitary radium application combined with external 60Co irradiation was the main treatment method. The most frequent complication was radiation proctitis, but fistulas occurred only in 1.6 per cent.
