Changes to This Summary (07/03/2014)

The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.

Polycythemia Vera

Added Quintás-Cardama et al. as reference 21.

Primary Myelofibrosis

Added text to state that about 60% of patients with primary myelofibrosis carry a JAK2 mutation, and about 5% to 10% of the patients have activating mutations in the thrombopoietin receptor gene, MPL. Also added that almost 90% of the patients without JAK2 or MPL carry a somatic mutation of the calreticulin gene, which is associated with a more indolent clinical course than is seen with JAK2 or MPL mutations (cited Klampfl et al. and Nangalia et al. as references 6 and 7, respectively).

Essential Thrombocythemia

Added text to state that about 60% of patients with primary myelofibrosis carry a JAK2 mutation, and about 5% to 10% of the patients have activating mutations in the thrombopoietin receptor gene, MPL. Also added that almost 90% of the patients without JAK2 or MPL carry a somatic mutation of the calreticulin gene, which is associated with a more indolent clinical course than is seen with JAK2 or MPL mutations (cited Klampfl et al. and Nangalia et al. as references 7 and 8, respectively).

Added Quintás-Cardama et al. as reference 23.
