When looking at polycythemia vera (PV), essential thrombocythemia (ET), and myelofibrosis (MF), how is risk determined? Dr. Brady Stein explains factors he examines when assessing risk to provide ideal care for each patient. 

Dr. Brady Stein is a hematologist focusing on myeloproliferative neoplasms (MPNs) at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University. Learn more about Dr. Stein, here.

Dr. Stein:                  

For ET and PV, when we talk about high versus low risk, we’re talking about vascular complications, risk of having a blood clot. We’re not really talking about risk of transformation. We don’t have, I think, wonderful, widely used toolkits to predict those things. We know they can happen, but our treatment is still really based on clotting for ET and PV.

And, MF – each couple of years, the tools that are available to assess prognosis become more and more. So, in MF, we’re using the most comprehensive approach – of course, taking into account things like age and demographics, but also, looking at symptoms, looking at the depth and severity of blood count changes, looking at bone marrow features like the degree of scarring, looking at the rise in blast counts, and then, looking at chromosomes and novel genetic markers. So, we’re definitely the most comprehensive in myelofibrosis at assessing prognosis.
