Finazzi G et al. - Low-risk PV patients should be managed only with phlebotomy and aspirin, whereas high-risk patients should also receive cytotoxic therapy. Regarding the management of ET, there is no clear indication for intervention in low-risk patients, whereas high-risk patients should be managed with chemotherapy. Other therapeutic options, such as interferon- or anagrelide, may find place in selected patients including those who are resistant/intolerant to hydroxyurea. Finally, there is great expectation for novel drugs targeting the constitutively active JAK2/STAT pathway.
