| Stereotactic body radiotherapy | Radiation | All patients will undergo planning CT simulation. 4-dimensional CT will be used for tumors in the lungs or liver. For all lesions, the gross tumor volume (GTV) will be defined as the visible tumor on CT and/or MRI imaging +/- PET. A Planning Target Volume (PTV) margin of 3-5 mm will be added depending on site of disease, immobilization, and institutional set-up accuracy. The prescirbe dosage was as following: Lung lesion DT50-60 Gy/5 fractions; liver 50-60Gy/5-8 fractions; brain DT 40Gy/4-5fractions. All will be treated with SBRT |
