| ABSTRACT |
|
Myasthenia gravis (MG) is relatively rare occuring as one of important autoimmune disease to affect neuromuscular junction. This study was clinically to evaluate total body irradiation (TBI) against two patients including 33-year and 39-year females for chronic MG with thymoma who hospitalized in the St. Mary's Hospital, Catholic University since 1994 as well as who showed no response by thymectomy, immunotherapy and hormonal therapy. TBI designed by the dose of 150~180 cGy consisting of 10 cGy per fraction, three times a week, for 5~6 weeks using linear accelerator of 6 MV. During the treatment of TBI, they did complain acute side effect such as vomiting and also appear improved physical condition from 4~6 weeks after TBI. Through the follow-up period of 18 or 42 months after TBI, they did not have any symptomatic recurrence. Consequently, the results suggest that TBI can be used as an alternative tool for the patients concurrently for MG with thymoma who had been refractory to various conventional therapies like thymectomy, immunotherapy and hormonal therapy. |
