 The usual treatment for sarcomas that spread to the lungs is to remove the cancer with surgery. Patients who cannot have surgery or prefer not to have surgery, can receive radiation therapy. Standard radiation therapy involves several weeks of daily treatment sessions, although it is not as effective as surgery and may seriously damage normal surrounding lung tissue. Stereotactic body radiation therapy SBRT is a radiation treatment that gives fewer but higher doses of radiation than standard radiation. SBRT is used to treat metastases to the lung from many types of cancer but has not been used very often with patients who have metastatic disease to their lungs from sarcomas.
