I certainly have my fingers crossed for good Pet/CT and MRI reports.
You have more options than you think you have.
Pertuzamab was approved the beginning of June. It can be used off label for other uses than it was intended.
It is most often used as a first line therapy with Herceptin or TDM1, but I heard some doctors are using it for second as third line therapies.
Also Tykerb can be used with other drugs like Abraxane, Taxol, Navelbine and Iexmpra. It does not always have to be used with Xeloda or Herceptin.
My doctor in Hong Kong recently told me he has been having alot of success recently with Tykerb and Taxol or Abraxane.
Sometimes combining drugs in different combinations allows better synergy than in combinations they were originally approved for.
If your doctor seems to think your options are limited it may be time to consider a second opinion.
All the best to you. Take good care of yourself and get a little more sleep. You earned it.
