The Freiburg cases of chronic neutrophilic leukaemia, arranged in chronological order

Patient	Sex	Age (years)	BCR/ABL-status	WBC (×10⁹/l)	% N	Hb (g/l)	Plt. ×10³	F-Up (months)	SpM	NAP	Outcome
In patients 2–8, 10, 11 and 13 the outcome was fatal. Haematological data are those found at the time of diagnosis. *, indicates that the patient is alive and the number indicates the number of months since diagnosis; †, indicates that the patient is dead and the number indicates the number of months after diagnosis.
BMT, bone marrow transplantation; CR, complete remission; F-Up, follow up period; Hb, haemoglobin; IF-α, interferon α; %N, % of neutrophils; NAP, neutrophil alkaline phosphatase score (normal range, 20–120); NI, not investigated; Plt., platelet count; SpM, splenomegaly; WBC, leucocyte count; (+), mild form.
