Chrisy had some wonderful suggestions Sheila.
It might be time to talk to some other oncologists about other options. Doctors are human beings. One doctor cannot be all things to all people no matter how smart or wonderful he or she is. One doctor cannot know everything about everything.
I alternate between two oncologists and a nurse practioner in the same office. I also keep in touch with my former oncologist who is now practicing medicine in Asia. All three doctors have different knowledge bases, experiences and have worked with different patients, so they each have something very valueable to contribute, suggest or share with me. The nurse practioner is also very helpful, because she has a wide knowledge base. I learn so much every time I see them.
It also helps to help cover all bases and make sure nothing is left on the table or forgotten.
The chemo sensitivity testing seems like a good idea too.
I think it can be done if there are several skin mets are one large skin met.
If your insurance won't approve Pertuzamab you may be able to get help from the drug company that makes it or a cancer organization that can put you in touch with an organization that provides financial assistance or grants to patients for medicines.
Hang in there Sheila. Take good care of yourself.
