Abstractor Notes

(This code is effective for cases diagnosed 2010 and later. For cases diagnosed prior to 2010, see code 9684/3.)

Most patients present with Stage III/IV. Because these tumors are negative for CD20 antigen, they are insensitive to rituximab.

Diagnostic Confirmation

This histology can be determined by positive histology (including peripheral blood) with or without genetics and/or immunophenotyping. Review the Definitive Diagnostic Methods, Immunophenotyping and Genetics Data sections below, and the instructions in the Hematopoietic Manual for further guidance on assigning Diagnostic confirmation.

Definition

ALK-positive large B-cell lymphoma (LBCL) is an aggressive neoplasm of ALK-positive monomorphic large immunoblast-like B cells, which usually have a plasma cell phenotype.

Definitive Diagnostic Methods

Genetic testing
Histologic confirmation
Immunophenotyping
Karyotyping

Immunophenotyping

ALK protein positive
CD3- (no expression/negative)
CD20- (no expression/negative)
CD30- (no expression/negative)
CD45- (no expression/negative) or weak
CD79a- (no expression/negative)
