Thymic Epithelial Tumor
Conditions
Brief summary
The purpose of this study is to determine whether stereotactic body radiotherapy (SBRT) combined with recombined human granulocyte-macrophage colony stimulating factor(rhGM-CSF) and Peginterferon alfa-2b is safe, effective in the treatment of patients with metastatic thymic epithelial tumors.
Interventions
DRUGrhGM-CSF，Peginterferon alfa-b2，radiation
Radiation: If there are two measurable lesions totally, One lesion received radiotherapy for 30 Gy in 5 fractions and rested for one week; If there are three measurable lesions totally, two lesion received radiotherapy for 30 Gy in 5 fractions separately. drug: Patients were injected subcutaneously rhGM-CSF 125mg/m2 per day from day1 to day 14, every three weeks, concurrent with radiotherapy. Peginterferon alfa-b2 90 ug in d8 in each cycle. And the 1 month after the end of all radiotherapy courses, 4 weeks as a course of treatment, once per course of treatment, each dose is 90μg until desease progress.
