Overview
The incidence of polycythemia vera is approximately 0.8 to 2.6 per 100,000 individuals per year in the US. The prevalence of polycythemia vera is 48 to 57 cases per 100,000 individuals in the United States. Males are more commonly affected than females. The life expectancy is variable but is typically more than 10 years for patients who have uncomplicated polycythemia vera and is significantly shorter in the case of post-PV myelofibrosis or post-PV acute myeloid leukemia.
Epidemiology and Demographics
Incidence
- The incidence of polycythemia vera is approximately 0.8 to 2.6 per 100,000 individuals per year in the US.
Prevalence
- The prevalence of PV is estimated to be 44 to 57 cases per 100,000 persons, and approximately 148,000 persons are living with PV in the United States.[1][2]
Age
- Polycythemia vera occurs in all age groups (including children), the incidence increases with age.
- The median age at diagnosis is 61 years but has been diagnosed in all age groups (including children).[3]
- Younger patients have comparable rates of vascular complications compared to older patients. However, splanchnic vein thrombosis occur more frequently in younger patients.[4]
- Younger patients are more likely to develop unusual complications such as mesenteric venous thrombosis. The rate of transformation to acute leukemia is similar as that of older adults.[3]
Gender
- Males are more commonly affected with polycythemia vera than females. However, about 75% of patients less than 40 years who are diagnosed are females.[3]
Life expectancy
- The life expectancy after diagnosis is 13.5 years.[5] For patients who develop post-PV myelofibrosis or post-PV acute myeloid leukemia, the life expectancy is significantly shorter. Please see Natural History, Complications, and Prognosis section.
