Transarterial chemoembolisation of colorectal liver metastases with irinotecan-loaded beads: What every interventional radiologist should know.

The last decade has seen important developments in the treatment of metastatic colorectal cancer (mCRC). In this scenario, interventional locoregional treatments could play an expanding role offering safe and effective integrated options in the continuum-of-care offering curative as well as palliative approaches. Based on ESMO guidelines, the toolbox of ablative treatments also includes intra-arterial palliative options, like chemoembolization, that can be offered as an alternative option in patients failing the available chemotherapeutic regimens. However, to date, there is still a limited use of chemoembolization in clinical practice. Based on this background, a comprehensive review of the methodologic and technical considerations as well as clinical indications and future perspectives seems to be useful with the aim to demonstrate the field's value of the procedure, highlight their advantages, and ensure an increased role in treatment management of patients with colorectal liver metastases.
