Hepatic intra-arterial injection of Yttrium-loaded microspheres for liver metastasis secondary to colorectal cancer: best soups are sometimes made from old recipies.
Colorectal cancer is a severe disease with a significant incidence in Western world. In the course of disease, about 40% of patients will eventually develop metastases to the liver. The majority of them will never be candidate for curative surgical management. For those patients, systemic or intra-hepatic chemotherapy is the treatment's cornerstone. Unfortunately, despite evident improvements and apparition of several active new agents, no hope of cure emerges on the agenda for now. Hepatic intra-arterial injections of radioactive devices have since a long time drawn interest from the medical community. An anti-tumoural activity has been demonstrated with Yttrium-loaded microspheres injected in the hepatic artery for several liver neoplasms including metastases from colorectal cancer. We lack however the results of large randomized phase III trials to define clearly the place of those interventional therapies in the management of colorectal cancer metastatic to the liver.
