Question:

Reportability--Heme & Lymphoid Neoplasms: Is polycythemia, NOS reportable? See Discussion.

Discussion:

The physician states the patient has polycythemia. There is no confirmation of primary polycythemia nor is there mention of polycythemia vera. JAK2 was negative.

Answer:

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Polycythemia, NOS is not reportable. Polycythemia, NOS is not a synonym for polycythemia vera and, therefore, is not reportable. To be reportable the diagnosis must be polycythemia vera, or one of the other terms listed in the Alternate Names section of the Heme DB.

Polycythemia (also known as erythrocytosis) is a disease state in which the proportion of blood volume that is occupied by red blood cells increases. Blood volume proportions can be measured as a hematocrit level. It can be due to an increase in the mass of red blood cells ("absolute polycythemia"); or to a decrease in the volume of plasma ("relative polycythemia").

History:

This SINQ question has been updated to the Hematopoietic & Lymphoid Neoplasm Manual & Database published January 2014.

The original answer below was written based on the rules in 2012

No, this case is not reportable. Polycythemia (also known as polycythemia or erythrocytosis) is a disease state in which the proportion of blood volume that is occupied by red blood cells increases. Blood volume proportions can be measured as hematocrit level. It can be due to an increase in the mass of red blood cells; "absolute polycythemia"; or to a decrease in the volume of plasma ("relative polycythemia").

To be reportable the diagnosis must be polycythemia vera, or some of the other alternate names listed in the 2012 database.
