I was first diagnosed Stage3 in Aug. 2014, ER+PR+Her2-. Found metastases in bones and lymph nodes in Dec. 2023, bioposied one node, same biomarkers. I was put on Tamoxifen which shrank many lesions, except for one. After that, I went through Tamoxifen, Letrozole + Kisqali, Faslodex + Kisqali, have scan every 3 months. Every time, there are lesions shrinking and others growing. I start to think the metastases are heterogenous -- the responding lesions are ER+PR+Her2-, the non-responding lesions might be Her2+ or triple negative. I did a quick online research, apparently heterogenous metastases is a well-documented, common phenomenon. So, my questions is: has anyone had similar experience? what's the treatment strategy for those patients who have different biomarkers from different sites?
I received my PET scan result today, seeing my onc tomorrow. Praying for strength and guidance from God...
