Current prognostics tests (excluding PraediCare Dx) for AML fall far short of clinical utility: “Resistance Prediction in AML”. Roland Walter. Leukemia, 2014.

“The AUC of a bootstrap-corrected multivariable model predicting this outcome was only 0.78, indicating only fair predictive ability. Removal of FLT3-ITD and NPM1 information only slightly decreased the AUC (0.76). Prediction of resistance, defined as primary refractoriness or short relapse-free survival, was even more difficult.”
