Medical journalist Hiroo Matsui talked about Keytruda (Merck), a cancer drug for dreams, on radio of this morning. The system to kill cancer cells by losing efficacy of PD-1 is the same as pioneeer Opsibo (Ono Pharmaceutical Co.), but before using Opsibo we must use anticancer drugs, Keytruda do not need it and had a much higher effectiveness, so he talked as a dream cancer treatment agent. It is expected that similar more effective drugs will come out one after another, and it seems that the time when cancer is cured with medicine is close.
