Overview
The incidence of polycythemia vera is approximately 0.7 to 2.6 per 100,000 individuals in the US.[1]
Epidemiology and Demographics
Incidence
The incidence of polycythemia vera is approximately 0.7 to 2.6 per 100,000 individuals in the US.[1]
Prevalence
The prevalence of polycythemia vera is 48 to 57 cases per 100,000 individuals in the United States. This represents the age-adjusted prevalence as of 2010. The prevalence of polycythemia vera is 5 to 30 cases per 100,000 individuals in Europe.[2] Approximately 148,000 persons are living with polycythemia vera currently.[3] It is likely that this is an underestimate of the true prevalence, as many patients are asymptomatic.[3]
Age
The median age of polycythemia vera is 61 years.[3][2] Polycythemia vera occurs in all age groups (including children). The incidence increases with age. Polycythemia vera commonly affects people older than 60 since mutations are more likely to develop with aging.[1][4][5] 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, with a male to female ratio of 6.5:3.5.[1][2][2] However, in patients under age 40, there is a female predominance of 7.5:2.5.
Life expectancy
The life expectancy after diagnosis is 13.5 years.[2]
