Lyn..too bad we don't know if those 37% women in the study were HER2. (The % is right.) I have posted before that I am ER/PR negative and have taken estriol cream from a compouding pharmacy for a year. I can only say that my hot flashes vanished, I sleep soundly and my sex life is good thanks to the cream. I wouldn't want to go back to my life as it was before. The only thing it hasn't helped with is my chemo brain.
My internist has done this for me once the onc told me it was okay, I had complained about not being able to have sex anymore. The vanishing hot flashes and great sleeping were a surprise to everyone. I had a hormone profile done by ZRT labs 3 months after taking it and will have one done every year. This I do on my own.
If I were ER/PR positive... I would be confused too. I have read articles stating that some estrogen may be beneficial when taking those estrogen inhibitors. They were posted a few months ago. Anyone have those saved? Good luck with all of this.
