Chemoembolization with CalliSpheres drug-eluting beads loaded with irinotecan in the treatment of unresectable colorectal cancer liver metastases: preliminary results in 16 cases.

Background: To analyze the perioperative safety and effectiveness of chemoembolization with CalliSpheres drug-eluting beads (DEBs) loaded with irinotecan (DEBIRI) in the treatment of unresectable colorectal cancer liver metastases (CRCLM).

Methods: The clinical data of 16 colorectal cancer patients with postoperative liver metastases who were treated with chemoembolization using DEBIRI in our center from March 2017 to December 2018 were retrospectively analyzed. The treatment responses 3 and 6 months after the chemoembolization was evaluated with the modified Response Evaluation Criteria in Solid Tumors (mRECIST).
