[Loco-regional therapy for liver malignancy in Iceland].
Transarterial chemoembolization (TACE) is a loco-regional therapy performed to treat tumors in the liver. The branch of the hepatic artery supplying the tumor is catheterized and a mixture of iodized oil, chemotherapeutic agents and PVA embolic materials infused. TACE is a palliative treatment of unresectable cancer in the liver but can also be employed as adjunctive therapy to liver resection and/or radiofrequency ablation. The procedure can in certain instances downstage the disease and provide a bridge to liver transplantation. The aim of this study was to evaluate outcome in patients that have undergone loco-regional therapy in Iceland and the frequency and severity of complications related to the procedure.



All Icelandic patients that had undergone TACE, transarterial chemotherapy or bland embolization of liver tumors between 1 May 2007 and 1 March 2011 were included in the study.



Eighteen TACE, six transarterial chemotherapy treatments and two bland embolizations were performed on nine patients with hepatocellular carcinoma (HCC), and three patients with carcinoid metastases in the liver. Mean-survival of patients with HCC was 15.2 months. Survival of patients with carcinoid metastases was between 61 and 180 months. Complete response was achieved twice and partial response four times. The disease remained stable after eleven procedures but progressed after three procedures. Minor complications were diagnosed in 6 of 26 procedures and one major complication. No patient suffered from liver failure due to the procedure. Of the 9 HCC patients, 1 patient was on the liver transplant list before TACE and later underwent successful transplantation. Additionally, 3 of the remaining 8 patients were downstaged and put on to the transplant list.
