From: GIPSS: genetically inspired prognostic scoring system for primary myelofibrosis

Genetically inspired prognostic scoring system (GIPSS)-stratified survival data in 641 patients with primary myelofibrosis. Median survivals were 2 years for GIPSS high risk, 4.2 years for intermediate-2, 8 years for intermediate-1, and 26.4 years for low risk. The number of patients at risk for high, intermediate-2, intermediate-1, and low risk GIPSS at 5 years were 15, 61, 150, and 41; at 10 years 4, 15, 41, and 17; and at 15 years 2, 5, 16, and 10
