A patient came in anemic with a hemoglobin of 6.9 and was transfused after 6 days. Over six days hemoglobin dropped to 6.1 (scoped found polyps/removed) then gradually began to climb up to 6.3 at which time he was transfused; now at 9.5 and stable. No alternatives were explored.

Now he is diagnosed with myelodysplasia currently being treated with vitamin B-12.

Could you provide some treatment options?
