I've had the JAK2 mutation with essential thrombocytosis for the past 8 years. Started treatment with hydroxyurea but it gave me bad mouth sores so my doctor switched me to Anagrlide, which I've tolerated very well. But my hemoglobin started dropping and after lots of tests he did another bone marrow biopsy and found that it had morphed into myelofibrosis. Says I may have 4-5 years left if I do nothing and that the only possible cure is a complete bone marrow transplant. It scares me to think about it. He also said there may be some kind of JAK2 pill. Does anyone know anything about that? Thanks.
