Abstract: Liver is the most common site of colorectal cancer metastasis. Patients with oligometastasis may achieve long-term survival after local ablative therapy within the context of improved systemic therapy. Stereotactic radiotherapy (SRT) can deliver radical ablative doses in a small number of fractions precisely. We will discuss the safety and efficacy of SRT for liver oligometastatic disease, compare with other local treatment modality, and how to choose patients who can real benefit from SRT. We represent target volume delineation and dose limitation standard. Finally, we discuss the development of new radiotherapy technology and possibility of SRT to combined with systemic therapy.
