Worsley et al modified the original Bournemouth score to predict survival in patients with chronic myelomonocytic leukemia. The authors are from Royal Victoria Hospital in Bournemouth.
> 10 g/dL
<= 10 g/dL
> 100,000 /µL
<= 100,000 /µL
bone marrow blasts
> 16,000 /µL
2,500 to 16,000 per µL
< 2,500 /µL
• For the original Bournemouth score, a neutrophil score = 2,500 would be scored 1 point (<= 2,500).
total score =
= (points for hemoglobin) + (points for platelet count) + (points for bone marrow blasts) + (points for neutrophil count)
• minimum score: 0
• maximum score: 4
• The lower the score the better the survival.
An additional risk factor was absolute monocyte count > 2,600 per µL. However, analysis of this factor did not reach the same significance as including the increase in the absolute neutrophil count.
