Overview
If left untreated, patients with polycythemia vera may progress to develop headache, fatigue, and dyspnea. Common complications of polycythemia vera include bleeding, thrombosis, tinnitus , and splenomegaly. Prognosis is generally good with treatment, and the median survival for patients with polycythemia vera is around 10.9 to 27.8 years.[1]
Natural History
The symptoms of polycythemia vera usually develop in the sixth decade of life and start with symptoms such as headache and fatigue.[2] If left untreated, the natural history of polycythemia vera will result in post-polycythemia vera (post-PV) myelofibrosis and acute myeloid leukemla (AML).[3] The median time to development of myelofibrosis is 8-20 years.
- The cumulative risk of developing myelofibrosis is 6% at 10 years, 14% at 15 years, and 26% at 20 years from the initial diagnosis of polycythemia vera.[3]
- The risk of developing acute myeloid leukemia is 2% at 10 years, 5% at 15 years, and greater than 10% at 20 years from the initial diagnosis of polycythemia vera.[3]
Complications
Polycythemia vera may lead to the following complications:[2][4][5][6][7][8]
- Thrombosis: Clot formation occurs in 15% of patients with polycythemia vera.
- Deep venous thrombosis: Clots can develop in the deep veins of the lower extremities, such as the popliteal vein or femoral vein.
- Pulmonary embolism: Clots can develop in the segmental or subsegmental arteries of the pulmonary vasculature.
- Myocardial infarction: Clots can develop within the coronary arteries, and this is usually exacerbated by underlying cardiac risk factors.
- Stroke: Clots can develop in the anterior or posterior circulation in the brain.
- Budd-Chiari syndrome: Clots can develop in the hepatic vein.
- Splanchnic vein thrombosis: Clots can develop in mesenteric vasculature like the splenic vein, superior mesenteric vein, inferior mesenteric vein, or portal vein.
- Epistaxis: Bleeding can occur in the anterior or posterior circulation of the nasal cavity.
- Gingival gums: Bleeding gums is typically seen after brushing teeth.
- Menorrhagia: Pelvis bleeding commonly occurs in pre-menopausal females.
- Metrorrhagia: Irregular pelvic bleeding can occur in pre-menopausal females.
- Petechiae: Pinpoint hemorrhages can occur in the skin.
- Splenomegaly: Extramedullary hematopoiesis occurs when the bone marrow is unable to sustain normal cell production.
- Gout
- Peptic ulcer
- Myelofibrosis: This is a condition in which the bone marrow becomes replaced by collagen and reticulin fibers. When myelofibrosis occurs in the setting of polycythemia vera, it is referred to as post-polycythemia vera (post-PV) myelofibrosis. Myelofibrosis carries an overall poor prognosis given that collagen fibers preclude normal hematopoiesis, resulting in infections, bleeding, and fatigue.
- Acute myeloid leukemia: This is a malignancy of the hematopoietic stem cell (specifically myeloid precursors). It is characterized by clonal proliferation and resultant cytopenias and ineffective hematopoiesis. Patients typically die as a result of infections and/or bleeding.
- Hearing impairment
- Visual impairment
- Paresthesia
- Headache
Prognosis
The prognosis of polycythemia vera is good with treatment. Without treatment, polycythemia vera will result in death.[1] Once myelofibrosis or acute myeloid leukemia ensues, the prognosis is very poor.
