Classical Hodgkin lymphoma (cHL) is characterized by nearly universal genetic alterations in 9p24.1, resulting in constitutive expression of PD-1 ligands. This likely underlies the unique sensitivity of cHL to PD-1 blockade, with response rates of ∼70% in relapsed/refractory disease. There are now numerous clinical trials testing PD-1 inhibitors in earlier stages of treatment and in combination with many other therapies. In general, non-Hodgkin lymphomas (NHLs) do not display a high frequency of 9p24.1 alterations and do not share cHL's vulnerability to PD-1 blockade...

Gray zone lymphoma (GZL) is described as sharing features with classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL). However, there remains complexity in establishing diagnosis, delineating prognosis, and determining optimum therapy. Sixty-eight cases diagnosed as GZL across 15 North American academic centers were evaluated by central pathology review to achieve consensus. Of these, only 26 (38%) were confirmed as GZL. Morphology was critical to GZL consensus diagnosis (eg, tumor cell richness); immunohistochemistry showed universal B-cell derivation, frequent CD30 expression, and rare Epstein-Barr virus (EBV) positivity (CD20+, 83%; PAX5+, 100%; BCL6+, 20%; MUM1+, 100%; CD30+, 92%; EBV+, 4%)...

Background In a phase 1 trial, axicabtagene ciloleucel (axi-cel), an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy, showed efficacy in patients with refractory large B-cell lymphoma after the failure of conventional therapy. Methods In this multicenter, phase 2 trial, we enrolled 111 patients with diffuse large B-cell lymphoma, primary mediastinal B-cell lymphoma, or transformed follicular lymphoma who had refractory disease despite undergoing recommended prior therapy. Patients received a target dose of 2×106 anti-CD19 CAR T cells per kilogram of body weight after receiving a conditioning regimen of low-dose cyclophosphamide and fludarabine...

Primary mediastinal B-cell lymphoma (PMBCL) is recognized as a distinct clinicopathologic entity that predominantly affects adolescents and young adults and is more common in female subjects. Although PMBCL is considered to be a subtype of diffuse large B-cell lymphoma, its clinical, morphologic, and biological characteristics overlap significantly with those of nodular sclerosing Hodgkin lymphoma (NSHL). Over the past few years, the shared biology of these 2 entities has been highlighted in several studies, and mediastinal gray zone lymphoma, with features intermediate between PMBCL and NSHL, has been recognized as a unique molecular entity...

In the present article, the authors reviewed the rationale of FDG-PET/CT performed at an interim time point during therapy (iPET), focusing on the transition from standard, anatomical assessment of tumor shrinkage with CT to document a chemotherapy response, to the use of functional imaging with PET to assess chemosensitivity of the individual tumor. The prognostic or predictive role of iPET in different lymphoma subsets has been reviewed, with particular emphasis on early and advanced-stage Hodgkin lymphoma, diffuse large B-cell lymphoma, peripheral T-cell lymphoma, extranodal natural killer/T-cell lymphoma, and primary mediastinal B-cell lymphoma...

AIMS: Mediastinal gray zone lymphoma (MGZL) is a rare entity with morphologic, immunophenotypic, and genetic features intermediate between classic Hodgkin lymphoma (CHL) and primary mediastinal large B-cell lymphoma (PMBL). It is challenging to differentiate from CHL and PMBL. A specific dendritic cell gene expression profile can distinguish CHL and MGZL from PMBL. We hypothesized that the dendritic markers fascin and CD123 may be helpful in distinguishing MGZL from CHL and PMBL. We also investigated programmed death-ligand 1 (PD-L1) expression in MGZL, which may have therapeutic significance in this difficulty to treat tumor...

The management of diffuse large B-cell lymphoma (DLBCL) has been gradually evolving since the discovery of its 2 major forms, the germinal center B-like (GCB) and activated B-cell (ABC) types. Although the reference standard for the identification of these cell types is considered gene expression profiling (GEP), currently the only method commercially available is immunohistochemistry (IHC). The application of various IHC-based algorithms and their correlation with GEP and clinical outcome are discussed. Because of the adverse prognostic implications of the non-GCB type and its potential effects on treatment selection, the recently revised World Health Organization classification has included these biologic cell types...

The success of immunotherapy using immune checkpoint blockade in solid tumors and in relapsed/refractory classical Hodgkin lymphoma and chronic lymphocytic leukemia holds promise for targeted therapy in hematologic malignancies. Since efficacy of immunomodulatory therapy is correlated with numbers of cells that express programmed death (PD-1) ligands, we evaluated the expression of PD-L1 and PD-L2 proteins using immunohistochemistry in over 702 diagnostic lymphoma biopsies. In classical Hodgkin lymphoma, PD-L1 and PD-L2 were expressed in 82% and 41% of cases respectively, and PD-L1 but not PD-L2 expression correlated with Epstein Barr Virus in tumor cells...

Over the period 2010-2012, maternal mortality linked to anesthesia accounted for 2% of maternal deaths, with no significant change since 2007-2009. Of the 7 maternal deaths analyzed by the expert committee, anesthetic complications were in 5 cases the main cause of death: 4 attributed to direct causes related to anesthetic procedures during childbirth and 1 to indirect cause in connection with an ENT complication during pregnancy. The anesthetic causes of maternal mortality were for the 2010-2012 period: cardiac arrest under spinal anesthesia during caesarean section, local anesthetic intoxication with unsuccessful resuscitation after cardiac arrest without intralipid administration, acute respiratory distress syndrome in the postpartum period after pulmonary aspiration during caesarean section, cardiac arrest during caesarean section under general anesthesia in a context of non-Hodgkin lymphoma with mediastinal syndrome, unsuccessful endotracheal intubation in a context of cellulitis of the oral cavity floor...

PD-1 blockade targeting the PD-1 immune checkpoint has demonstrated unprecedented clinical efficacy in the treatment of advanced cancers including hematologic malignancies. This article reviews the landscape of PD-1/PD-L1 expression and current PD-1 blockade immunotherapy trials in B-cell lymphomas. Most notably, in relapsed/refractory classical Hodgkin lymphoma, which frequently has increased PD-1+ tumor-infiltrating T cells, 9p24 genetic alteration and high PD-L1 expression, anti-PD-1 monotherapy has demonstrated remarkable objective response rates (ORR) of 65-87% and durable disease control in phase I/II clinical trials...

Treatment with dose-adjusted EPOCH (etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone) chemotherapy and rituximab (DA-EPOCH-R) has become the standard of care for primary mediastinal B-cell lymphoma (PMBCL) at many institutions despite limited data in the multi-centre setting. We report a large, multi-centre retrospective analysis of children and adults with PMBCL treated with DA-EPOCH-R to characterize outcomes and evaluate prognostic factors. We assessed 156 patients with PMBCL treated with DA-EPOCH-R across 24 academic centres, including 38 children and 118 adults...

The development of clinically functional chimeric antigen receptor (CAR) T cell therapy is the culmination of multiple advances over the last three decades. Axicabtagene ciloleucel (formerly KTE-C19) is an anti-CD19 CAR T cell therapy in development for patients with refractory diffuse large B cell lymphoma (DLBCL), including transformed follicular lymphoma (TFL) and primary mediastinal B cell lymphoma (PMBCL). Axicabtagene ciloleucel is manufactured from patients' own peripheral blood mononuclear cells (PBMC) during which T cells are engineered to express a CAR that redirects them to recognize CD19-expressing cells...

Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma. It includes three major subtypes termed germinal center B-cell-like, activated B-cell-like, and primary mediastinal B-cell lymphoma. With the emergence of novel targeted therapies, accurate methods capable of interrogating this cell-of-origin classification should soon become essential in the clinics. To address this issue, we developed a novel gene expression profiling DLBCL classifier based on reverse transcriptase multiplex ligation-dependent probe amplification...

Between 2007 and 2013, 13 children diagnosed with primary mediastinal large B-cell lymphoma (PMLBL) were treated according to a modified version of AIEOP (Associazione Italiana Ematologia Oncologia Pediatrica) LNH-97 protocol based on high-dose methotrexate, anthracyclines, and addition of anti-CD20. Ten patients achieved a continuous complete remission with front-line therapy. The overall 5-year survival was 91.7%, and event-free survival was 83.9%, with only one patient dying of progressive disease. Despite the few cases, these results demonstrate that this therapy, which includes anti-CD20, given in a multicenter setting, is feasible with acceptable toxicity in children with PMLBL...

Diffuse large B-cell lymphoma (DLBCL), a high-grade lymphoproliferative disease, is the most common lymphoma in adults, representing 31% of non-Hodgkin lymphomas (NHL). In elderly patients treatment is problematic because of the high toxicity of standard chemotherapy protocols, especially in relapsed cases, where high-dose chemotherapy and haematopoietic stem cell transplantation would be the best choice. More and more data is becoming available on alternative treatment of refractory/relapsed NHL, including studies on the positive effect of thalidomide and second generation IMiDs in DLBCL, which are already part of the standard treatment protocol in myeloma multiplex and myelodysplasia...
