Abstractor Notes

(This code is effective for cases diagnosed 2010 and later. For cases diagnosed prior to 2010, see codes: 9728/3 [lymphoma] or 9836/3 [leukemia].)

The specific etiology of leukemia with MLL translocations is unknown; however, it may occur in utero, with a short latency between the translocation and development of neoplasm. Evidence for this statement includes the fact that these leukemias are frequent in very young infants.

Diagnostic Confirmation

This histology can only be determined by positive genetics and/or immunophenotyping, diagnostic confirmation will always be 3.

B lymphoblastic leukemia/lymphoma with t(v;11q23); MLL-rearranged

Definition

B-lymphoblastic leukemia/lymphoma with t(v;11q23.3) is a neoplasm of lymphoblasts committed to the B-cell lineage in which the blasts harbor a translocation between KMT2A (also called MLL) at band 11q23/3 and any of a large number of fusion partners. Leukemias that have deletions of 11q23.3 without KMT2A rearrangement are not included in this group.

Definitive Diagnostic Methods

Bone marrow biopsy
Genetic testing
Immunophenotyping

Genetics Data

AFF1 (AF4) on chromosome 4q21
FLT-3 overexpression
KMT2A gene on chromosome 11q23.3
KMT2A MLLT1 fusions
KMT2A-rearranged
MLLT1 (ENL) on chromosome 19p13
MLLT3 (AF9) on chromosome 9p21.3
t(v;11q23.3)

Immunophenotyping

CD10- (no expression/negative)
CD15+ (expression/positive)
CD19+ (expression/positive)
CD24- (no expression/negative) pro-B immunophenotype
NG2 homologue encoded by CSPG4

Treatments

Chemotherapy
Hematologic Transplant and/or Endocrine Procedures
