Observations on 73 cases of Ewing's tumor confirmed that this neoplasm occurs in twice as many males as females, mostly between the ages of 11 and 20. In contrast with other reported series, 61.6% of lesions in our patients were in the flat bones. Definite diagnosis cannot be based solely on clinical and radiological changes, and no patient suspected of suffering from Ewing's tumor should receive x-ray treatment or any other kind of therapy unless the diagnosis has been proved histologically, by means of open biopsy. Supervoltage radiation therapy combined with chemotherapy produces better results than other kinds of treatment. |
