[Prognostic criteria of survival in the treatment of Ewing's sarcoma, reticulosarcoma and myeloma].

The data are reported on the 3- and 5-year survival in 177 patients with Ewing's sarcoma, reticulosarcoma and myeloma. Better late results were gained under the repeat course of chemo-hormonal and radiation therapy. In male patients with Ewing's sarcoma the survival rate is found to be reliably higher; the prognosis is better with tumors located in flat bones (excluding the pelvis) and upper extremities, the age having no influence on issues. No correlation was found between the survival of patients with reticulosarcoma and their age and tumor localization, the prognosis being more favourable in aged subjects. Sex and age do not effect the prognosis in patients with melanoma, the results being better in case of a solitary myeloma, located in the spine, and worse--in pelvic bones.
