Hi, I also have TNBC after my initial cancer being estrogen positive (4yrs ago). It’s now in my bones, 5 tumours. I did have a significant tumour marker jump, up to about 300 back in June 2021 and yes did all the CT and Pet scans to find out what was going on. The waiting is the hardest, but now that I am down the track, it was critical because the oncologist consult their networks and try to work out the best available treatment.
I went on oral chemo first - Capecitabine - and that did help reduce the markers initially. But then I was able to access Trodelvy, which is a new drug for TNBC and apparently has amazing results! So ask your onco about Trodelvy.
For both, the side effects are manageable. Capecitabine was definitely easier, ver time convenient as no hospitals and IV. Check out the other chat on Capecitabine; it can have some yukky side effects.
Trodelvy is early days but definitely harsher - nausea, fatigue, lost my hair.
But if it works! 🤞
