Initial WBC of > 100,000 was seen in 19% of patients. The most common FAB subtype was M4 39%. Twenty three patients underwent treatment out of which 12 patients are alive and in remission. Majority were followed up around 2 years and 6 months. Out of the 11 patients who died three had resistant disease, four relapsed and rest died due to sepsis mostly during induction.
