[Diagnosis and treatment of mesenchymal chondrosarcoma].

Eight cases of mesenchymal chondrosarcoma (3 males and 5 females aged 15-65) are described. Morphological examination revealed in all cases biphasal tumor consisting of the chondroid tissue of varying maturity and undifferentiated tissue. Combination and complex treatment was given to 6 patients. In 4 cases, radiotherapy was carried out in combination with chemotherapy and local electromagnetic hyperthermia. Out of 8 patients, seven are still alive and are examined at 4 month - 11 year intervals (average of 39.7 months). One female patient died 12 months after the beginning of treatment. Combined and complex procedures should be recommended for treatment of such patients.
