Patients risk classification in HMs.

Risk group Type of HMs

High risk(i) Advanced stage Burkitt’s lymphoma/leukemia (B-ALL)
(ii) Lymphoblastic lymphoma with LDH ≥ 2 × ULN
(iii) Early stage Burkitt’s lymphoma/leukemia with LDH ≥ 2 × ULN
(iv) ALL with WBC count ≥ /L or less if the baseline elevation of LDH is twice ULN
(v) AML with WBC count ≥/L
(vi) Diffuse large B-cell lymphoma (DLBCL) with an elevated baseline LDH of twice ULN, and bulky disease

Intermediate risk(i) AML with a WBC between /l and /l or <25 × 109/L if the baseline elevation of LDH is twice ULN
(ii) ALL with WBC < /L and an LDH of less than twice ULN
(iii) Early stage Burkitt lymphoma/leukemia with an LDH of less than twice ULN
(iv) DLBCL with a baseline increase in LDH of twice ULN but nonbulky disease
(v) CLL with WBC ≥ /L
