HAI-Floxuridine, or Liver-Tx, Combined With 2nd Line Chemotherapy Versus 2nd Line Chemotherapy Alone for Patients With Colorectal Liver Metastases and Heavy Tumour Burden.

Patients with colorectal livermetasteses and heavy tumour burden and progression on 1st line chemotherapy have no other available treatment in Norway today other than 2nd line chemotherapy. The Investigators will randomize patients to HAI-floxuridine (FUDR), or liver-Tx, in addition to 2nd line chemotherapy versus 2nd line chemotherapy alone (Excalibur 1) or systemic chemotherapy with HAI/FUDR versus systemic chemotherapy alone (Excalibur 2). Primary endpoint is overall survival at 2yrs.
