Abstract
Modern systemic therapies provide a significant survival benefit in metastatic colorectal
cancer. Despite these advances, the durability of response remains limited and nearly
all patients progress on systemic treatment. Colorectal liver metastases (CLM) develop
in approximately half of patients with metastatic disease and contribute to mortality
in most patients. In selected patients, surgical resection of hepatic metastases prolongs
survival, indicating the benefits of the targeted treatment of CLM through alternate
means. Minimally invasive interventional treatments offer the promise of treating
CLM in a wider range of patients than those eligible for surgical resection. Thermal
ablation and intra-arterial therapies, including chemoembolization and radioembolization,
are commonly used in the treatment of CLM. Each of these treatment modalities will
be discussed in detail with an emphasis on the available clinical data for each interventional
treatment for CLM.
