Myelofibrosis is a serious bone marrow disorder that disrupts your body's normal production of blood cells. The result is extensive scarring in your bone marrow, leading to severe anemia, weakness, fatigue, and often, an enlarged spleen and liver. Myelofibrosis is an uncommon type of chronic leukemia — a cancer that affects the blood-forming tissues in the body. Myelofibrosis belongs to a group of diseases called myeloproliferative disorders.
Somatic mutation in the exon 14 of Janus Kinase 2 gene is an established diagnostic marker in bcr-abl negative myeloproliferative neoplasms. Clinical and hematologic features were reviewed for 68 patients with primary idiopathic myelofibrosis (PIMF). JAK2V617F mutation status was analyzed by amplification refractory mutation screening-polymerase chain reaction. The JAK2V617F mutation was detected in 58.8% patients.
In the past, the treatment of myelofibrosis has depended on the symptoms and degree of the low blood counts. A long-term remission is possible for some patients with bone marrow transplantation. Such treatment should be considered for younger patients and some others. Other treatment may involve:Blood transfusions and medicines to correct anemia, Radiation and chemotherapy, Medicines to target a genetic mutation, Splenectomy if swelling causes symptoms, or to help with anemia.
