Thank you so very much for the clarification. I want to get on Herceptin/trastuzumab because my HER 2 score is 3+ , the worst. Insurance wouldn't approve it and won't until other treatments have proved useless. Right now I have "mixed results." My oncologist tried hard to get it for me, and also appealed to the drug company for compassionate freebie, but no luck. The justification for denial is that it isn't yet approved for uterine cancer - just breast cancer. I have Untited Health Medicare. Would love to hear from others if you got approved for Herceptin/trastuzumab with your insurance, and what insurance you have. Maybe I could use that to make an appeal. "All these other companies approve it, so join the club." I haven't seen PD-1 on my lab report. I'll look again. There is a study on using Ivermectin against PD one at Cedar Sinai in LA . Not sure how it worked out. Any know anything about Ivermectin use? It doesn't cost much so there isn't any incentive for drug companies to spend a lot of dollars to study it. No return on investment. If I'm pMMR how does that connect with PD -1, if at all?
