About Polycythemia Vera
Polycythemia Vera is one of the myeloproliferative neoplasms, a group of blood cancers in which bone marrow cells multiply uncontrollably. In PV, the overproduction of red blood cells increases blood volume and viscosity (thickness), which impairs blood flow and oxygen delivery despite elevated hemoglobin levels. The high blood viscosity also increases risk of blood clots (thrombosis) and bleeding complications. About 95% of PV patients carry the JAK2 V617F mutation, with most remaining cases having mutations in CALR or MPL genes.
These mutations cause uncontrolled cell growth independent of normal growth signal regulation. Patients often present with constitutional symptoms including fatigue, headaches, and visual disturbances. The pathognomonic symptom of aquagenic pruritus (itching triggered by water contact) occurs in about half of patients. Splenomegaly (enlarged spleen) occurs in 75% of patients. Long-term complications include risk of thrombotic events (stroke, heart attack, deep vein thrombosis) and potential transformation to myelofibrosis or acute leukemia.
Common Symptoms of Polycythemia Vera
Recognizing the signs of Polycythemia Vera early can lead to faster diagnosis and better outcomes. Symptoms may vary in severity from person to person. If you or a loved one are experiencing any of the following, consider speaking with a specialist.
- Fatigue and weakness
- Headaches and dizziness
- Vision disturbances or blurred vision
- Itching, especially after bathing
- Burning sensations in the hands and feet
- Easy bruising or bleeding
Who Polycythemia Vera Affects
Polycythemia Vera typically affects older adults, with median age of diagnosis around 65 years, though it can occur at younger ages. It affects males and females approximately equally. The disease occurs across all racial and ethnic groups. Approximately 95% of PV patients carry the JAK2 V617F mutation, which can be detected through blood testing.
