I expect they will try it in liver cancer with Nexavar. There is a PEG-Interferon Alfa trial ongoing in liver cancer - <a href="http://www.clinicaltrials.gov/ct2/show/NCT00375661?term=PEG-Interferon+Alfa-2b+liver+cancer&rank=4" target="_blank">http://www.clinicaltrials.gov/ct2/show/NCT00375661?term=PEG-Interferon+Alfa-2b+liver+cancer&rank=4</a> and kidney cancer with Nexavar - <a href="http://www.clinicaltrials.gov/ct2/show/NCT00589550?term=PEG-Interferon+Alfa-2b+kidney+cancer&rank=1" target="_blank">http://www.clinicaltrials.gov/ct2/show/NCT00589550?term=PEG-Interferon+Alfa-2b+kidney+cancer&rank=1</a> I am not knowledgeable about the differences in the interferons. I have recently been diagnosed with liver cancer and intend to share my "findings" with the board if I live long enough to write a 1000 words.
