B-ALL with BCR-ABL11


B-lymphoblastic leukemia/lymphoma (B-ALL/LBL) with t(9;22)(q34.1;q11.2); BCR-ABL1 is a neoplasm of lymphoblasts committed to the B-cell lineage in which the blasts harbor a translocation between BCR on chromosome 22 and the ABL1 oncogene on chromosome 9.

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].)

This neoplasm occurs in both children and adults. Children usually have a better outcome.

This neoplasm is confirmed by immunological markers and/or ultrastructural cytochemistry.

Definitive Diagnostic Methods

Bone marrow biopsy
Genetic testing
Peripheral blood smear

Genetics Data

ABL1 at 9q34.1
Fusion of BCR at 22q11.2
