Bossywife, I apologize that I can't remember your husband's total experience. From everything (studies) I have followed is that Vidaza (or Dacogen) and perhaps a combination with lenalidomide followed by a stem cell transplant are the only paths of treatment that have quality results for RAEB II. What have your husband's doctors suggested about this path? I have always been prescribed Vitamins D and B12, but these are nothing that will turn around genetic mutations. The "extra stuff" just helps in general health support.
age 70, dx RAEB-2 on 11-26-2013 w/11% blasts. 8 cycles Vidaza 3w/Revlimid. SCT 8/15/2014, relapsed@Day+210 (AML). Now(SCT-Day+1005). Prepping w/ 10 days Dacogen for DLI on 6/9/2017.
