Dear Linda,
How sad that Al's blast cells have increased! If this depends on Promacta the blast cells will hopefully decrease when the drug is stopped.
Induction chemotherapy means only treatment with drugs aimed at inducing a remission. Many drugs can be used but in MDS they often use Cytarabine. Then there are many trials where they combine different drugs for better effect:
