Hi and welcome to OCF

Thats a lot to deal with in such a short space of time,and it must be very difficult to get your head round.If i am honest it doesn't sound the most encouraging news,but in view of the extensive treatment she has undergone the medics must have felt that there was hope for a good outcome when they undertook the surgery.I am surprised they didn't scan her body for spread before the treatment plan was started in view of the already recognized aggressive nature of the disease,but this particular form of cancer can run a very unpredictable course.

What exactly is the "antibody treatment " she is having?

In terms of what to expect,that depends very much on the doctors opinion on what the likely outcome is going to be,so i would get some more detailed information,and then ask the questions.Is this curable,or treatable ,and what are the options?Whatever the answers there will be someone here who's had trodden the same path and will be able to help.
