[Course and outcome of treatment of synovial sarcoma].

The results of exploration of 126 patients with synovial sarcoma are reported; males -- 70, females -- 54, aged from 4 to 74 years old. The tumor was found to be localized as follows: the extremities -- 117 (upper -- 33, lower -- 84), and the body -- 9 patients. Seven structural variants of synovial sarcoma were differentiated: 1) alveolar -- 19, 2) adenomatous -- 10, 3) histioid -- 65, 4) perithelial --3, 5) fibrous -- 6, 6) gigantic-cell -- 3 and 7) mixed -- 20 patients. The patients were treated surgically (56 patients) and using the combined technics (70 patients). The most favourable results were noted in treatment of patients with adenomatous and fibrous types of synovial sarcoma, worse issues -- in patients with gigantic-cell and perithelial forms. Synovial sarcomas of histioid and mixed types occupy the intermediate place. The most malignant character of the neoplasm was observed in patients with alveolar tumor.
