Hi Wherenext,
To follow the response you have to look at the counts as you already have understood. The important counts are HGB, WBC, ANC and platelets.
Your mother's HGB has decreased, her WBC has increased, her ANC is very low at 0.18 - 0.42. Look out for infections! We don't know anything about her platelets. Hopefully they are OK.
Most doctors wait 6 months before they evaluate the effects of Vidaza treatment.
Since you mention the BCL2L10 gene I think you perhaps can understand quite complicated info. Here are the response criteria for MDS patients:

Many patients respond even if they don't meet the IWG criteria.
Kind regards
