Comparative Analysis of the Efficacy of Irinotecan-loaded Drug-eluting Beads (DEBIRI) in Combination With Systemic Chemotherapy Versus Chemotherapy Alone in Unresectable Colorectal Cancer Liver Metastases: a Randomized Clinical Trial
A total of 116 patients who meet the inclusion criteria and are chemotherapy-naïve for their metastatic disease, will be randomly assigned to either the treatment group (DEBIRI plus systemic chemotherapy) or the control group (systemic chemotherapy alone). After 4 cycles of chemotherapy and 2 cycles of DEBIRI, patient reassessment to evaluate treatment response, based on RECIST criteria, will be performed using MRI or CT scan within 1-3 months of treatment initiation. The feasibility of secondary tumor resection, as primary endpoint, will be reassessed at a three-month follow-up multidisciplinary team (MDT) meeting, guided by established clinical guidelines.
