I am writing for my mother who has mbc. So far she has received anastozole, nolvadex for the early stage, and for mbc fulvestrant +ibrance, paclitaxel, capecitabine, she is currently on vinorelbine iv. He has metastases on the liver and bones, so far he is stable. liver biopsy: er 70%, pr 0%, her2 1+, ki67 18%; pik3ca negative, brca negative. eribulin, halaven, orserdu, enhertu are not available here. So we need a suggestion of what other therapies (perhaps older chemo) would come into consideration? The oncologist says he has nothing another to give her. Help, suggest what to do next...
