Very few members have had Lu 177 and those that have in various countries, so not entirely surprised at lack of replies with regard to this type of treatment in Germany. As you will doubtless have established, there are a number of hospitals offering this treatment and Germany has a good record of providing advanced treatment. (I had rare RT treatment in Germany and my UK second opinion who had experience of German Hospitals had been impressed by them). My understanding is that the cost will vary most depending on the number of infusions a patient is given but also local hospital costs, so you would need to check this with several of the hospitals and seek opinions on their reputations. It would certainly be very expensive regardless. The effectiveness of this treatment seems to vary considerably and NICE considered it was not cost effective, although this was due for a review in January and is currently underway. I understand you are desperate for a treatment to buy more time having been told there are no other possibilities. A patient has first to establish he is suitable for this form of treatment as you are most probably aware.
I would be less concerned between which of a number of leading German Hospitals to choose between as to how many infusions were to be given but how successful the treatment itself might be, weighed against the total experience and cost
