Brief summary
Single arms prospective phase II study of SBRT for oligometastatases from colorectal cancer
Detailed description
Single arms prospective phase II study of SBRT for oligometastatases from colorectal cancer, the primary concerns are treatment efficacy and toxicities.
Interventions
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
