Despite your dismissivness gnu, this is a unique approach which has not "been done before", at least not on solid tumours. If it proves to be as effective in humans as it is in the mouse model then it will be very promising indeed. It is quite an elegant system in that it utilizes the host's immune system to eliminate the tumour by neutralizing it's defense against this happening. The use of the word "drug" in the article is somewhat of a misnomer in that it is not a drug in the sense of being a chemical formulation but rather it is a normal human protein in the form of an antibody. This should significantly decrease much of the unwelcome side effects of conventional anti-cancer chemotherapy.

Oh, and thank you for you tip on how to find other threads but I am quite familiar with that function.
