Stereotactic Ablative Radiation Therapy for Colorectal Liver Metastases.

Introduction: Stereotactic Ablative Radiation Therapy (SABR) is a therapeutic option for patients with inoperable oligometastatic colorectal carcinoma (CRC). Given the scarcity of prospective data on outcomes of SABR for metastatic CRC, this study aims to review SABR outcomes and determine predictive factors of local control (LC) and survival in patients with liver metastases from CRC.

Materials And Methods: A retrospective review of SABR for CRC liver metastases between 2011 and 2019 was undertaken.
