Patnaik et al reported a simple score for evaluating patients with chronic myelomonocytic leukemia (CMML). The authors are from the Mayo Clinic.
Patient selection: CMML
Parameters:
(1) absolute monocyte count in 10^9/L
(2) circulating immature myeloid cells
(3) hemoglobin in g/dL
(4) platelet count in 10^9/L

Interpretation:
• minimum score: 0
• maximum score: 4
• The higher the score the greater the risk.
