Osterroos et al reported a score for predicting early mortality for a patient with acute promyelocytic leukemia. This can help to identify a patient who may require more aggressive management. The authors are from multople institutions in Sweden.
Patient selection: acute promyelocytic leukemia
Outcome: early death (death within 30 days)
Parameters:
(1) age in years
(2) WBC count in 10^9/L
(3) platelet count in 10^9/L
