Hi Chirley,
As far as I understand metamyelocytes can be found in blood in infections or other causes of "marrow stress". Perhaps the marrow stress is increased in the beginning of treatment with Vidaza when all counts can decrease before Vidaza kicks in and as you know that can take up to 6 cycles.

How are you? We have not got any info from you during the last days though it is a good sign that you are able to follow yor counts so closely.
Kind regards
