Taxotere and Abraxane are potentially active taxanes after Taxol exposure. Gemzar and Abraxane may be a very good combination. Ixempra, Halaven, Pemetrexed, Xeloda...various endocrine therapies still untouched...could be combined with some of those chemos and/or Her2 therapies. Metronomic dosing options of same chemos. Maybe Everolimus soon...Metformin
A single spot in liver could be cryoablated. Same with small spots in lung.
Hopefully in the meantime advancements in immuno therapies.
