Re: Why Capecitabine and Exemestane?
Affinitor is used in combination with Aromosin because in ER+/Her2 negative bc when Armidex or Femara has failed. It's the way the study was run and nothing more. Generally, the biochemical reaction in the body to inhibit the conversion androgens to estrogen is by inhibiting aromotase ( the catalyst for this reaction). Armidex and Femara use the same mechanism for this. Aromosin inhibits in a different mechanism.
I think your Xeloda question has a similar answer. Xeloda inhibits the synthesis of dna by inhibiting a chemical needed. It works differently than the other drugs mentioned and so the combo has a bigger punch by shutting down multiple mechanisms on reproduction.
