International Prognostic Score of Thrombosis in World Health Organization–Essential Thrombocythemia (IPSET-Thrombosis)

The primary objective of essential thrombocythemia (ET) management is to prevent thromboembolic complications. In this regard, advanced age and thrombosis history were used to assess this risk. More recently, JAK2V617F and cardiovascular (CV) risk factors were identified as additional modifiers, leading to the development of a 3-tiered International Prognostic Score of Thrombosis for ET (IPSET-thrombosis): “low,” “intermediate,” and “high”.

Total 6 points (Age 1, H/O Thrombosis 2, Cardiovascular risk factor 1 and JAK2V617F – 2 points)
