Prognostic factors were identified in 2000 by the Italian Group for Adult Hematologic Diseases (GINEMA) and Spanish PETHEMA group in a 217-patient multivariate analysis. [26] These researchers proposed risk stratification based on WBC and platelet count, as follows:

  • Low risk - WBC < 10,000/μL and platelets >40,000/μL

  • Intermediate risk - WBC < 10,000/μL and platelets < 40,000/μL

  • High risk - WBC >10,000/μL and platelets < 40,000/μL
