Calculator: Mayo chronic myelomonocytic leukemia (CMML) prognostic model in adults (conventional and SI units)


Calculator: Mayo chronic myelomonocytic leukemia (CMML) prognostic model in adults (conventional and SI units)

 
Input
 
White blood cell count  
Percent monocytes   %
Circulating immature cells No (0)

Yes (defined as: myeloblasts, myelocytes, metamyelocytes, and/or promyelocytes) (1)
Decreased hemoglobin No (0)

Yes (<10 g/dL [<100 g/L]) (1)
Decreased platelets No (0)

Yes (<100 x 103/microliter [<100 x 109/L]) (1)

 
Results
 
Important: Inputs must be complete to perform calculation.

 
 
Absolute monocyte count  
Score   points
 

 

 

CMML prognosis score interpretation

 
0 points: Low risk; 32 months median survival
1 point: Intermediate risk; 18.5 months median survival
2 to 4 points: High risk; 10 months median survival

 
 

 
Notes
  • Absolute monocyte counts >10,000/microL [>10 x 109/L] contribute one point to the CMML prognosis score.

 
Equations used
 
Absolute_monocyte_count = White_blood_cell_count * Percent_monocytes / 100
Score = (1 if the following expression is true, 0 if false)(Absolute_monocyte_count > 10000) + Circulating_immature_cells + Decreased_hemoglobin + Decreased_platelets

 

 
Equation parameters, such as Circulating immature cells, have two or more discrete values that may be used in the calculation. The numbers in the parentheses, eg, (0), represent the values that will be used.
 

 
Only digits 0 to 9 and a single decimal point (".") are acceptable as numeric inputs. Attempted input of other characters into a numeric field may lead to an incorrect result.
