Abstract

Objectives: Evaluation of post-operative radiotherapy results for thymic cancer by IMRT technique at national cancer hospital. Subjects and Methods:Including 45 patients with thymic cancer stage II, III, IVA. Postoperative radiotherapy by IMRT with radiation dose of 50-60 Gy. Result: Patients with thymic cancer stage II 37.8%(n=17), stage III 57.8%(n=22), stage IVA 4.4%(n=6), in which type Thymoma accounted for 60%(n=27), Thymic carcinoma accounts for 40%(n=18). The disease-free overall survival rate after 2 year is 100% in stage II, 95.5% in stage III and 16.7% in stage IVA. Type Thymoma has a 100% disease-free overall survival rate, and the rate of thymic carcinoma is only 66.7%. Recurrence, distant metastases were found in patients with stage III, IVA in thymic carcinoma type. Conclusion: Stage II gives 100% disease-free survival, III  95,5%, and IVA 16,7%. Thymoma type 100%, Thymic carcinoma  66,7%.
