In this episode, we discuss the diagnosis and management of Essential Thrombocythemia with Dr. Raajit Rampal. Here are the shownotes:1.     IPSET (revised) system, risk categories are defined by the presence of a prior thrombosis, age, and JAK2 mutation status:
·        Very low risk: No prior thrombosis, age ≤60 years, JAK2-unmutated
·        Low risk: No prior thrombosis, age ≤60 years, JAK2-mutated
·        Intermediate risk: No thrombosis, age >60 years, JAK2-unmutated
·        High risk: History of thrombosis (any age/genotype), or age >60 years with JAK2 mutation

5.    Ruxolitinib  
In a randomized study phase 2 study (MAJIC-ET), ruxolitinib treatment did not deliver better rates of hematological response than best-available therapy, although symptoms did improve. 
 
·        MAJIC-ET study which is a randomized phase 2 trial 
·        ET patients resistant/intolerant to HU were randomized to receive RUX or standard treatment (HU 71%, anagrelide 48%, IFN 40%). The primary study outcome was CR, defined by normal platelet and white cell counts and normal spleen size.  
·        At 1 year, response was achieved in 46% of patients in the RUX group and in 44% in the standard arm, without statistically significant difference between the two groups.  
·        In addition, no difference was observed in the rates of thrombosis, hemorrhage, and disease transformation after 2 years of follow-up.  
·        MRs were also uncommon. RUX was superior, however, in symptom control.
