jack14 Posted February 20, 2021 Share Posted February 20, 2021 Does anyone know if Keytruda can shrink a tumor for awhile, and after another set of infusions, have no effect on it, and then after another round, shrink it again, or show no growth again? In other words, can it's effects be intermittent? The side effects certainly vary and are intermittent. Anyway, I asked my PA Oncologist and all she said was "if Keytruda stops working, and we discontinue it, we never return to it". So, I guess that suggests that once it stops working, it is no longer effective? Of course, at 15 thousand dollars a dose, or whatever it is, I bet the insurance carrier is all for "moving on". I would like to add that, although my knowledge of pharmacology is somewhat limited, what I do know, tells me that drug efffects can be easily altered by storage temps, preparation, manufacturing snafus, and sometimes they just don't result in the same effects or actions that we desire. I also know that Keytruda for instance, is mixed up a few minutes prior to infusion and that it is not to be shaken, and even when it isn't, it can form air bubbles in it and that is something that the maker has warned about. Maybe, there are some things that are happening behind the scenes that are causing this drug to not work as it should. I once asked the RN who was terminating my infusion if I could have the infusion set for a momento and she said said "sure" let me disconnect the bag and you can have the set. I said, it was the empty bag that I wanted, and she replied, "oh, no, that has to be turned in to the pharmacy". She added, that it was policy. .
