I came across a study today, which was published a few weeks ago and clarifies this with even more recent information. This is more important, now that I am scheduled with Stem Cell transplant.

MM, without stem cell transplant and chemotherapy, the median life expectancy is 50 months from diagnosis.

MM with stem cell transplant, and reduced chemotherapy, life expectancy is 70 months from diagnosis.

More adverse reactions in group 1 and more complications.

So, I think stem cell transplantation is the right choice.
