Elacestrant/Orserdu
1QT.2024 My TM CA-15-3 went up. I am very nervous. I just started Elacestrant its my 2nd week and i am getting mixed messages here about that it causes spikes in tumormarkers activity for some patients and not so much for others. I was taken off my previous meds Kisqali+Letrozole on Jan 5th after PET scan that showed new progression in liver. On Jan 5 my CA-15 =67. Today ITS = 126! There's no way of knowing whether this activity happened when I was off meds from Jan 5 - Feb20 while sorting out NGS and deciding on the new treatment or just now on my 2nd week of taking Elacestrant.In addition I have ESR1 RNA FUSION nor the actual mutation. Please share your experience on this drug.. THANK YOU!
