Summary

Patients with intrahepatic cholangiocarcinoma (IHC) have relatively aggressive tumors, and the prognosis for most of these patients is dismal. Surgery is the only option that can offer potential cure, but only an estimated 20-25 % are amenable to resection. Down-staging conventional chemotherapy has a relatively low response rate (\< 50 %). Patients will be included into the respective treatment arms based on their tumour characteristics and disease stage, but also based on their ability/preferences, as HAI-FUDR/DEX requires going to Oslo every fortnight for the duration of the treatment and SIRT has some limitations regarding tumour distribution.

Data from the MSKCC has suggested a clinically relevant benefit from adding intrahepatic chemotherapy to systemic therapy. HAI-FUDR/DEX is not approved in Norway and can only be evaluated in a protocolized trial. Given the risk of distant disease progression with IHC, the addition of conventional systemic chemotherapy makes good clinical sense, and data from MSKCC supports this approach. SIRT is another modality also applied trans-arterially and directly into the tumour. This treatment is approved in Norway and available in Bergen and in Oslo. It is far less cumbersome to deliver and maintain than HAI-FUDR/DEX. The efficacy and safety of the two treatment groups, HAI-FUDR/DEX and SIRT, will be compared in a parallel cohort (non-randomized) design

Conditions

  • Intrahepatic Cholangiocarcinoma
  • Chemotherapy Effect

Interventions

DRUG

Floxuridine

A laparotomy will be performed and a catheter placed in the hepatic artery Connected to a subcutaneous pump. This pump will be percutaneously filled with Floxuridine 6 times in 2 weeks cycles, alternating with heparin-solution. The patients in this arm will also be given GemOX as systemic chemotherapy

PROCEDURE

Selective Internal Radiation Therapy (SIRT)

Radioactive Yttrium 90 (Y-90) labeled particles are injected selectively into the feeding arteries of the tumour(s). This allows a high radiation dose in the lesions while limiting systemic side effects.
