Calculation of Relative Risk of CML Patients

 

CHRONIC MYELOID LEUKEMIA
CALCULATION OF RELATIVE RISK (RR)
Age:   years
Spleen:   max. distance from costal margin cm x 10 (e.g. 6 cm = 60)
Platelet:   Plt 109 L  ( e.g 350000 ml = 350 )
Blood Basophils:   % x 10 ( e.g. 1.5% = 15 )
Blood Eosinophils:   % x 10 ( e.g 2.6% = 26 )
Blood Myeloblasts:   % x 10 ( e.g 0.7% = 7 )
 
 
Sokal RR: 
Hasford RR: 
 
  • Sokal JE et al, Blood 1984; 63: 789-799
  • Hasford J et al, JNTL Cancer Inst 1998; 90: 850-858
Notice
Spleen size, platelet count and differential must be measured and performed before any treatment No calculation should be made to assess the RR of pretreated or late chronic phase patients
