an·a·plas·tic large cell lym·pho·ma

Synonym(s): Ki-1+ lymphoma

anaplastic large cell lymphoma

A primary non-B cell non-Hodgkin lymphoma, usually of T cell lineage, which is immunoreactive for CD30 and often ALK (anaplastic lymphoma kinase) and characterised by scattered to abundant “hallmark cells”—medium-sized cells with abundant cytoplasm and kidney-shaped nucleus, which tend to aggregate around blood vessels. ALCLs arise either as a primary neoplasm in a node or lymphoid tissue, soft tissue, lung, or skin, or secondary to the transformation of a lymphoproliferative disorder (e.g., mycosis fungoides), T-cell lymphoma, lymphomatoid papulosis or Hodgkin lymphoma.
DiffDx Classical Hodgkin lymphoma.
Clinical findings Often a late-presenting lymphoma with “B symptoms” including night sweating and weight loss.
Molecular >90% have rearrangement of T cell receptor, chromosomal translocation involving the nucleophosmin gene on chromosome 5.
Management CHOP, radiation for bulky disease.

anaplastic large cell lymphoma

Abbreviation: ALCL
A rare form of non-Hodgkin, T-cell lymphoma that may behave indolently when limited to the skin or may be more aggressive and spread to lymph nodes throughout the body.

Anaplastic large cell lymphoma (ALCL) was first described in 1985 by Stein et al as a unique lymphoma characterized by large pleomorphic lymphoid cells, often with horseshoe-shaped nuclei and a sinusoidal growth pattern1.

The distribution of these subtypes includes 40% Burkitt lymphoma, 20% diffuse large cell lymphoma, 30% lymphoblastic lymphoma, and 10% anaplastic large cell lymphomas (1).
Biotechnology company Seattle Genetics Inc (NasdaqGS:SGEN) reported on Friday the receipt of approval from the Japanese Ministry of Health, Labour and Welfare (MHLW) for ADCETRIS (brentuximab vedotin) for the treatment of patients with CD30-positive relapsed or refractory Hodgkin lymphoma (HL) and anaplastic large cell lymphoma (ALCL).

Nasdaq:SGEN) today announced that Health Canada has issued a Notice of Compliance with conditions (NOC/c), authorizing marketing of ADCETRIS for two lymphoma indications: (1) the treatment of patients with Hodgkin lymphoma (HL) after failure of autologous stem cell transplant (ASCT) or after failure of at least two multi-agent chemotherapy regimens in patients who are not ASCT candidates, and (2) the treatment of patients with systemic anaplastic large cell lymphoma (sALCL) after failure of at least one multi-agent chemotherapy regimen.
Adcetris previously received approval with conditions in Canada for two lymphoma indications: HL patients who relapse after ASCT or relapse after at least two multi-agent chemotherapy regimens in patients who are not ASCT candidates; and for systemic anaplastic large cell lymphoma (sALCL) patients who relapse after at least one multi-agent chemotherapy regimen.
Takeda Pharmaceutical Company Limited today announced that the European Commission (EC) has approved a Type II variation for ADCETRIS (brentuximab vedotin) to include data on the retreatment of adult patients with relapsed or refractory (R/R) Hodgkin lymphoma or R/R systemic anaplastic large cell lymphoma (sALCL) who previously responded to ADCETRIS and who later relapse.
Although the diagnosis of entities characterized by specific genetic lesions, such as mantle cell lymphoma and ALK-positive anaplastic large cell lymphoma, has been simplified by ancillary testing modalities, other entities (such as nodal marginal zone lymphoma) lack such pathognomonic features.
