Colleagues worked in some project for cancer research where they connected terminally ill patient with certain studies. Most of these studies did the same thing, sequencing DNA of the cancer and then finding the right combination of medicines. It turned out that sometimes the treatment was too successful with the right combination, and it killed all cancer cells in a very short time. This was also bad outcome as it was very toxic. Anyway a bunch of people with very late stages did survive all of this and are now cancer free. So now the researchers try to match the DNA with the right amount of treatment to strike a balance.
