Elliott et al developed a simple risk score for evaluating patients with primary myelofibrosis. This is a modification of the Dupriez prognostic score and incorporates the monocyte count. The authors are from the Mayo Clinic and the MD Anderson Cancer Center in Houston.
Patient selection: age <= 60 years with primary myelofibrosis
Parameters:
(1) hemoglobin
(2) leukocyte count
(3) platelet count
(4) absolute monocyte count

where:
• The text refers to the absolute monocyte count as ">=" and ">" 1,000.
total score =
= SUM(points for all 4 parameters)
Interpretation:
• minimum score: 0
• maximum score: 4
• The higher the score the worse the survival.
