The aim of this study is to evaluate the immunocytochemical (ICC) expression of CD30, CD15, and PAX5 in Hodgkin's cells (HC) and Reed-Sternberg cells (RSC) on smears and cell-blocks (CB) of HL and to compare the performance of each antibody on smears and CB.
We sought to determine the utility of the novel YE361 STAT6 rabbit monoclonal antibody in Hodgkin lymphoma and diagnostically challenging B- and T-cell non-Hodgkin lymphoma entities with Hodgkin-like features.
Thirty-five patients diagnosed with HL who underwent <sup>18</sup>F-FDG PET/CT scans before and during chemotherapy were retrospectively enrolled in this investigation.
During characterization of a cDNA library from the Hodgkin lymphoma (HL) cell line L-1236, we discovered a new transcript derived from chromosome 1 at the long intergenic non-protein coding RNA 1768 (LINC01768)/colony stimulating factor 1 (CSF1) region.
The upregulated expression of the JAK/STAT pathway promotes tumor growth in Hodgkin lymphoma (HL) and primary mediastinal large B-cell lymphoma (PMBCL).
In addition, EBV-positive and -negative HL cases express survival, but not death signals of ER stress at similar levels and EBV-LMP1 transfection increases expression of survival signals in HL cell lines.
Patients respond well to chemotherapy with cure rates of 80-90% and the recent finding of PD-L1 expression, an immune checkpoint, warrants the use of immunotherapy for some patients with recurrent and/or refractory HL.
This patient is one of the five CD70 deficient individuals described to date, and presented hypogammaglobulinemia, EBV associated Hodgkin's lymphoma and susceptibility to other viral infections.
We evaluated clinical features and survival among patients ≤21 years of age diagnosed with stage I-IVHL from 2004 to 2015 from the National Cancer DataBase (NCDB) using a multivariable Cox proportional hazards model.
Interestingly, cells from the triplet treated for Hodgkin lymphoma in 1985 contained two subpopulations: one with high expression of CD11a that behaved like control cells and the other with low expression of CD11a that formed large tumors in vivo similar to cells from the undiagnosed triplet.
While cells from the Hodgkin lymphoma treated patients had a phenotype close to healthy controls, cells from the undiagnosed triplet had increased MKL1 mRNA, increased MKL1 protein, and elevated expression of MKL1-dependent genes.
Of note, brentuximab vedotin is an antibody-drug conjugate that targets CD30, another lymphocyte antigen expressed on the cell surface of both Hodgkin lymphoma (a variant of B-cell lymphoma) and some T-cell lymphomas.
