OS Risk of AML Time-dependent WPSS
Both from IPSS and WPSS, the estimated OS is about 2 yrs, and 5-yr survival probability is about 15-25% • Therefore, further treatment other than BSC is indicated. • ATG/CsA • Azacitidine/Decitabine • Allo-SCT
Will respond to immunosuppression? • NIH. A simple method to predict response to immunosuppressive therapy in patients with myelodysplastic syndrome. Blood. 2003; 102: 3025-3027. • ATG + CsA (regardless of blast percentage)
