Patient Selection Factors for Stereotactic Body Radiotherapy and Radioembolization for Hepatic Metastases

Abstract

Liver metastases are a common source of morbidity and mortality. Despite significant improvements in outcome with systemic therapy in recent years, it is infrequent that liver metastases or sites of macrometastatic disease are controlled permanently. Furthermore, most liver metastases are not amenable to what is considered the gold standard locally ablative therapy, surgical resection and consequently there has been a surge in interest in non surgical ablative therapies. Review of patient selection factors for two such liver directed radiation therapies, radioembolization and stereotactic body radiation therapy (SBRT) will be addressed.
