[Clinical x-ray characteristics and growth kinetics of Ewing's tumor].

The clinico-roentgenological peculiarities of the course of Ewing's sarcoma depending on tumor localisation were studied in 66 patients (29 in diaphysis and 37 in metaphysis). Tumor growth rates versus localisation (43 cases) and end results (55 cases) wee compared. The malignancy and growth rate of diaphysic tumors appeared to be higher. This was matched by lower survival rates. Statistical data on growth rates of tumor and survival are presented.
