RE:RE:RE:OVs improve cancer immunotherapy by reprogramming TME Why would they only prefer one? There are currently 50 kinds of chemotherapy divided into 4 types and chosen according to the patient, their cancer, previous treatments, stage, age, etc.... why it would be different for immunotherapies. As long as it works positively in synergy with something else (chemotherapy or whatever), there are companies that will want to have it in their choice of possibilities. I have never heard of an anti-cancer treatment that works well (better than the current choices), but which is not used, unless this treatment costs a fortune....and even then some people will want to get it.
