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][3]
  • 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

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.[4]
  • Thrombotic complications were the most common cause of death followed by hematologic malignancy.

Age

  • It has been noted that PV is more common in the age group >75.[5]
  • Median age of diagnosis is 60.[6]

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.[7]
  • In the analysis for the 7 MM countries, the percentage of prevalent males was higher than prevalent females.

Region

  • Incidence of cases is higher in the United States and Europe than in Japan.[8][9]
