    Abstract:
    To evaluate safety, efficacy of drug-eluting beads with irinotecan (DEBIRI) on local response and survival of patients affected by colorectal liver metastases (CRLM) progressing during or after second line was evaluated. Sixty-two patients, with colorectal liver metastases, not suitable for surgery or thermal ablation treatments, progressing during or within 6 month from the end of second-line chemotherapy, were treated with DEBIRI chemoembolization between February 2009 and July 2014. CRLM were histologically confirmed. Exclusion criteria were considered. The DEBIRI technique consists in intrahepatic embolization of metastases with non-absorbable beads (75-150 μm and 100-300 μm) preloaded with irinotecan, carried near tumour using a selective catheterization of the right or of the left hepatic artery. To control pain associated with treatment, we use a specific schedule. Efficacy of treatment, defined as lack of disease progression and reduction in size of metastasis according to RECIST 1.1 criteria, was evaluated after two treatments with contrast-enhanced computed tomography (CT) at 4 months. If necessary, more treatments are repeated. A total of 191 procedures were performed. No intra-/peri-procedural death occurred. Pain and post-embolization syndrome were generally controlled by medications. Overall, the efficacy of treatment, evaluated in terms of stability and remission of the disease, was 37.1%. In our experience, DEBIRI technique results as a safe and effective procedure, with good intra- and peri-procedural tolerability.
