If you have PV, your prognosis depends on many factors inclucing your age, other illnesses you have, and PV complications you may develop with PV. Blood clots (thrombosis) are common and are frequently serious; the risk of these events increases with age and previous episodes. The goal of PV treatment is to reduce the risk of complications and prolong your life.

Patients who suffer no other diseases (especially myelofibrosis or acute myeloid leukaemia) have a normal to slightly reduced life expectancy.

About 15% of people with PV develop a complication of the disease known as myelofibrosis. To read more about myelofibrosis, please click here:

Some patients with PV transform to acute myeloid leukaemia (AML). The onset of AML is rare but can have a poor outlook, as this form of leukaemia is often resistant to treatment. If this is a concern for you, please discuss with your haematologist.
