| Sumario: | Based on a personal series of 11 cases of Ewing’s sarcoma of bone, all with histological examination, the author discusses its histogenesis and main subjective symptoms e. g. pain, tumor and fever. He also studies the radiologic appearence of the tumor presenting pictures of several cases. The microscopic features are described. The roentgentherapy technics followed in the various cases are related. The tumor dose when the treatment preceded the operation varied between 1.200 to 1.600 r and in cases where it was used solely 3.000 to 4.200 r. In the 10 cases treated ths following results were obtained: of the 7 patients tre»ted by X-Ray, 2 are alive and free from smptoms, one of them with a survival of 5 years and 10 months and the other 10 months only; the other five died with generalised metastases. The 3 cases treated surgically died, the longest survival being 1 year and 3 months. Based on the experience acquired the A. believes that roentgentherapy must be the treatment of choice for these tumors. Surgery would be indicated in the cases of tumors localised in the limbs, when it’s not possible to imobilize the patient during the X-Ray treatment. Surgery would be contraindicated in the tumors localised in other bones. |
