The world of researching cures for cancer is a harrowing and interesting one. Every other week there appears to be new promises towards a cure highlighted in the headlines. This story is unfortunately not about any kind of success rate but rather, the death of three Leukemia patients receiving an immunotherapy clinical test. What’s interesting about the story isn’t the immunotherapy but the chemo used in tandem. They inject chemo to kill of any healthy white blood cells to give the new improved engineered cells a fresh platform to fight from. The researchers believe the chemo is what led to the deaths of the three patients. I am a very biased person against chemo after watching what it did to a friend of mine. And after realizing it exists because of mustard gas. I’m all for kicking chemo out of the equation. The research will continue without the chemo. I hope it helps.
