Hi Airlie. Everyone is treated differently at Hallwang according to testing that they carry out. My treatment would be different to everyone else's. If you Google Hallwang, they have a website with all their contact details, they also have a Facebook site. I contacted them by email, then the doctor called me to discuss treatment, they wanted to source my tumour tissue from here to see what treatment they could offer me, I had to sign an authority which they emailed to me to allow them to contact the pathology lab here. They also wanted a description of my diagnosis and treatment here, which I asked my oncologist to do and he did, so I emailed this to Hallwang. Then they came up with a treatment plan with costs for me to accept. It's quite expensive but different for everyone, so I really can't give you a ballpark figure. The reason for the cost is that Hallwang source there medicine from MDAnderson in America, and because it's off label, the medicine costs Hallwang a lot as well. Anyway google Hallwang or look at their Facebook site and you will see all kinds of information, and contact details. But most of all they are truly professional and very caring and test you before giving you any medicine, so it's not the same for everyone.
i hope I have been helpful. Oh and the oncologist there who I saw is Dr Nolting, he does research and is the most caring doctor I have ever met.
hugs to you
