Overview
- Not usually diagnosed in individuals below 60 years of age. Slightly more prevalent in men than in women according to some studies.
Epidemiology and Demographics
Incidence
- The incidence of polycythemia vera is approximately 1.9 per 100,000 individuals in the United States.[1][2]
- Taking into account all races and ethnicities, the incidence is approximately 2.8 per 100,000 males and 1.3 per 100,000 in females.
Prevalence
- The prevalence of polycythemia vera in the 7 MM countries was 283,442 in 2017.
- Prevalence of polycythemia vera was the highest in the US in 2017 at 157,290, out of which 62,916 cases were asymptomatic and 94,374 were symptomatic.
- 22 cases per 100,000 people.
Case-fatality rate/Mortality rate
- 4-year mortality rate is >10%.
- On average patients lived with the disease for 8.6 years (mean), the cases that were fatal were approximately 77.1 years of age on average.
- Comorbidities such as cardiovascular diseases, other blood, and lymphatic disorders, vascular disorders, mass occupying lesions in the thorax, respiratory system, infections, etc. accounted for more deaths more often.[3]
- Thrombotic complications were the most common cause of death followed by hematologic malignancy.
Age
Race
- Jews of Eastern European descent have a higher number of cases as compared to other Europeans or Asians.
Gender
- Generally, there is no sex predilection.[6]
- In the analysis for the 7 MM countries, the percentage of prevalent males was higher than prevalent females.
