Cathy's advice should be heeded,
and is probably the best advice for you at this time...... we all know cancer is very sneaky and always seems to have a plan "B", meaning it seems to change pathways such as HER2, E, VGEF, EGFR, etc. Even the triple negative cancers have some kind of pathway.... still unknown so far. This thing does not follow the rules and if you have a stubborn tumor, get the molecular / proliferation profile done so you can target the therapy. As Cathy so wisely suggested, the HER2 serum test is one and probably one of the least invasive. Another way is try different targetted drugs, if your doctor's progressive. For example, taking tarceva or iressa will first cause rashes and then tumor shrinkage, if you are HER1 +, the more the rash, the stronger HER1+ the better the drug. The problem is that many oncs, will stop all treatments rather than attempt an innovative salvage regimes. The trick is to get the pathways re-tested as soon as and however possible.
Good luck,
Al
