Abstract
This retrospective study evaluated the efficacy, safety, and factors affecting the prognosis of transarterial chemoembolisation with irinotecan-eluting beads with CalliSpheres (DEB-TACE) for intrahepatic cholangiocarcinoma (ICC). We retrospectively collected data on 39 patients with unresectable ICC who received DEB-TACE therapy. We assessed the indicators of tumour response, progression-free survival (PFS), overall survival (OS), and the incidence of adverse events. PFS and OS were analysed using Kaplan-Meier curves, while Cox analysis was used to identify factors affecting the prognosis. The 3-month objective response rate (ORR) and disease control rate (DCR) of the 39 patients with unresectable ICC were 35.9% and 56.4%, respectively, while the 6-month ORR and DCR were 23.0% and 40.9%, respectively. The median OS and PFS were 11.0months and 8.0months, respectively. Cox analysis demonstrated that combined therapy (adjuvant sorafenib after DEB-TACE) and a low cancer antigen (CA) 125 level (≤ 35 U/ml) were independent favourable prognostic factors. Transient elevation of the aminotransferase level, nausea, vomiting, abdominal pain, fever, and hyper-bilirubinaemia were common adverse events in patients with unresectable ICC treated with DEB-TACE with CalliSphere beads (CBs). Hepatic abscess was the most serious complication, observed in one patient. DEB-TACE with CBs is a safe and well-tolerated therapy in patients with unresectable ICC with a low incidence of adverse events and relatively prolonged survival. Combined therapy and low CA125 are prognostic factors associated with longer survival.
