“…In such a state an effective local therapy such as SBRT should, in theory, arrest the disease's progression and extend life.

The use of modern imaging to detect smaller lesions and the combined use with surgical and chemotherapeutic approaches makes SBRT a powerful tool to control disease progression in the oligometastatic state.…”
