Uveal mealnoma: Immunoembolization – pro

Uveal melanoma is a very difficult disease to treat and it has a poor prognosis. An approach developed at Jefferson University in Philadelphia has been termed Immunoembolization(IE) of the hepatic artery and it has been used to treat primary liver cancer (hepatoma), as well as liver metastases from uveal melanoma, neuroendocrine tumors, colorectal cancer and leiomyosarcoma. The rationale for this approach is that liver tumors receive their blood supply mainly from the hepatic artery, while normal liver is supplied with blood from the portal vein. The cytokines that have been used for immunoembolization at Thomas Jefferson University Hospital include GM-CSF, interleukin 2 (IL-2) and interferon alpha (IFN-alpha).
A phase II study by Yamamoto in 2009 cpmpared chemoembolization(CE) and IE. It concluded that treatment with high-dose IE prolonged survival of patients with uveal melanoma who received embolization of hepatic metastases and possibly delayed progression of extrahepatic metastases. This is a very interesting result but true comparative studies with more patients are needed before this coclusion will be widely accepted.
