I am posting on behalf of my husband Chris, diagnosed last April with Multiple Myeloma,no organ damage or lesions or symptoms,just picked up on a routine blood test. He is 67.Following very successful induction treatment last year and excellent care at Addenbrookes in Cambridge, he was very much on the Stem cell transplant trajectory. He was undecided for many of the reasons you have mentioned. In the end he went ahead with the collection of the stem cells which was very successful and these can be stored for up to 10 years. He agreed a break from treatment to consider his next steps and after a couple of months break when he generally felt well, he decided not to go for the STC but to try the Lenalidomide maintenance regime. We also felt there was little information about the prognosis without the transplant but I am guessing that is because in the UK, there is not much research data available as most patients have the treatment. Unfortunately the first dose of the Lenalidomide treatment made him very unwell and his consultant agreed for him to stop, have more blood tests and maybe go back to the treatment but on a lower dose of 5 mg. That is where we are at the moment. I think there is also the option to “Watch and wait” ie have no treatment but regular blood tests and resume treatment if there are indicators that the Myeloma has returned. I agree that quality of life is very important and my husband found it very hard to go from feeling perfectly well to suffering the various and prolonged side effects of the treatment. He could not face another year written off with no guarantee of a positive outcome. It is important to recognise that Myeloma is a very individual disease and different people react differently both physically and mentally and it is a big adjustment to make.
