Hi David,
The radiotherapy in 18 months or so is not such a long shot as it first seems.
Say you get 12 to 18 months from the Velcade (it's usually a pre-cursor to a 2nd SCT but gives you a fair remission on its own merits) by that time, as you get ready for the next step to Revlimid (and Dex of course) the newly licensed drug therapies from the US of A – Kyprolis (Carfilzomib) and Pomalyst (Pomalidomide) should both be up and running as available treatments, both running with Revlimid and Dex. Early indications look really good and 18 to 24 months look like being the median.:-)
So there could be 3 years on offer (perhaps more as further results come in from trials and early treatments – I wouldn't be surprised at 36 months from the combinations) which I think would put MM as the safer bet to run with as the main treatment, with the radiotherapy to keep the prostrate at bay. Who knows what else might be being prepared or even licensed in those 3 years? 😀
I'm still hoping to get a shot at Kyprolis (I missed the trial by 7 days:-P)… it was licensed last June so it can't be far off being licensed in Europe and the UK… I hope!
Regards and best wishes for whatever course you choose.8-)
Dai.
