Abstract: | Twenty-five patients with myeloproliferative diseases were treated with pegylated interferon alpha-2b. Prior to therapy, 15/25 patients had a JAK2(V617F) mutation. Eight JAK2-positive patients were on therapy in hematological complete remission at 24 months. Five of eight patients demonstrated a 1.2-3.6 fold reduction in the percentage of JAK2(V617F) cells. |
