Additionally, we advocate use of consolidative radiotherapy for localized and/or bulky disease. Interestingly, gain of Xq coincided with gain of 9p. 1. - Confirmed diagnosis of B-cell lymphoma, relapsed from or refractory to prior: - Cohort 1: B-cell lymphoma, unclassifiable, with features intermediate between. The aim of this subgroup analysis of the Mabthera International Trial Group study was to evaluate the impact of chemotherapy and rituximab in primary mediastinal B-cell lymphoma (PMBCL) in comparison to other diffuse large B-cell lymphoma (DLBCL). The overall response rate (ORR) and complete remission (CR) rate were both 75% (6/8) for all treated patients The median overall survival (OS) and progression-free survival (PFS) was 40.7 and 3.9 months, respectively. The immunophenotype is frequently discordant. However, as diagnostic criteria are imprecise, reliable identification of GZL cases remains challenging. Gray Zone Lymphoma. Mediastinal gray zone lymphoma (MGZL) has immunopathologic features between classical Hodgkin lymphoma (cHL) and primary mediastinal thymic B-cell lymphoma (PMBL), leading to uncertainty regarding its biological relationship to these entities. In young patients with PMBCL (age-adjusted International Prognostic Index 0-1), rituximab added to six cycles of CHOP-like chemotherapy increases response rate and EFS to the same extent as other DLBCL. Mediastinal gray zone lymphoma (MGZL) is an extremely rare type of Non-Hodgkin lymphoma with a predominance in young men [1]. No abnormality was found in cytogenetic analysis on tumor cells. We strongly recommend you discuss this information with your doctor. 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). GZL is a rare lymphoma with intermediate features between classical Hodgkin lymphoma (cHL) and Diffuse Large B-cell Lymphoma (DLBCL), but cannot be classified as one or the other [Evans, 2015]. Expression pattern of PD-L1 and PD-L2 in classical Hodgkin lymphoma, primary mediastinal large B-cell lymphoma, and gray zone lymphoma Eur J Haematol. Atlas Genet Cytogenet Oncol Haematol. Histologically, a lymphocytic infiltrate composed of monotonous small cells with scant cytoplasm was seen as well as calcification and fibrosis. Primary mediastinal B-cell lymphoma (PMBL) is a subtype of diffuse large B-cell lymphoma (DLBCL) that is putatively derived from a thymic B-cell. This resulted in a copy number increase of putative oncogenes, e.g., JAK2 (9p24) in 3 cell lines, FGFR3 (4p16) and CCND2 (12p13) in 2 cell lines as well as MYC (8q24) in 1 cell line. Gray zone lymphoma is a rare type of lymphoma, cancer of a part of the immune system called the lymph system.It is called "gray zone" lymphoma because it has features intermediate between classical Hodgkin lymphoma and diffuse large B-cell lymphoma (DLBCL), but cannot be assigned specifically to either type. 19, No. It is challenging to differentiate from CHL and PMBL. Seeing gray zone lymphoma not only as a cancer of the lymph nodes, but as one in a larger class of cancers dependent on use of the protein PD-L1 to … Gray-zone lymphoma (GZL), or B-cell lymphoma unclassifiable with features intermediate between diffuse large B-cell lymphoma (DLBCL) and classical Hodgkin lymphoma (CHL), is a diagnosis that spans the biologic spectrum between DLBCL, namely primary mediastinal large B-cell lymphoma (PMBL), and CHL, particularly nodular sclerosis (NS) subtype, encompassing tumors that … Tanaka Y, Maeshima AM, Nomoto J, et al.

Gray zone lymphoma with features intermediate between classical Hodgkin lymphoma and diffuse large B-cell lymphoma: characteristics, outcomes, and prognostication among a large multicenter cohort. Marginal zone lymphoma (MZL) is a group of indolent (slow growing) NHL B-cell lymphomas, which account for approximately eight percent of all NHL cases. Treatment with DLBCL-based therapy appears most effective for GZL (including R-CHOP); however, new therapies are needed to improve outcomes. We aimed at investigating the relationship between classical Hodgkin lymphoma (cHL ), primary mediastinal large B‐cell lymphoma (PMBL ), and gray zone lymphoma (GZL ) with intermediate characteristics between cHL and PMBL , from the perspective of the aberration in programed cell death 1 and the programed death ligands (PDL s) network. ?ller P, and Lichter P. Primary mediastinal (thymic) B-cell lymphoma is characterized by gains of chromosomal material including 9p and amplification of the REL gene. tic of Epstein-Barr virus–negative gray zone lymphoma cervical and tonsillar involvement. 1: 2600–2609. … Particularly striking was the finding that the median PFS of patients who received R-CHOP frontline chemotherapy was 11.4 months, which was superior to the median PFS of patients who did not receive R-CHOP. However, as to the latter, a longer follow-up period may be needed before stating the absolute equivalence of the two regimens used. 21. Recently, the recognition that mediastinal radiation is associated with significant long-term toxicities has led to the development of novel approaches for PMBL that have shown excellent efficacy and challenge the need for routine mediastinal radiation. Objectives. Overall survival benefit was similar for DLBCL (93% versus 85%, P < 0.001) and PMBCL (89% versus 78%, P = 0.158). Grossly, the specimen consisted of a trileaflet valve with multiple yellow-white focally hemorrhagic and calcified nodules over its surface. diffuse large B-cell lymphoma and classical Hodgkin lymphoma (i.e., Gray-zone. Introduction. However, this diagnostic gray zone is not just of theoretical interest: it presents a practical problem, as the treatment approaches for CHL traditionally differ from those for aggressive B-cell lymphomas. Each line was characterized by a highly heterogeneous pattern of karyotypic changes with a large spectrum of different translocated chromosomes (range 22-57). double hit lymphoma, there is a synergistic effect between MYC, BCL6 or/and BCL-2 as well as CD20, and every one of them draw its own gray zone in the field of diffuse large B-cell lymphoma. for the pathogenesis of MGZL is still unknown. 30: 1251–1260.

Expression pattern of PD-L1 and PD-L2 in classical Hodgkin lymphoma, primary mediastinal large B-cell lymphoma, and gray zone lymphoma. A recurrent finding in all cell lines was the presence of chromosomal rearrangements of the short arm of chromosome 2 involving the REL oncogene locus. Gray zone, grayzone, grey zone, or greyzone may refer to: . A specific dendritic cell gene expression profile can distinguish CHL and MGZL from PMBL. Primary Mediastinal Large B-Cell Lymphoma, Classic Hodgkin Lymphoma Presenting in the Mediastinum, and Mediastinal Gray Zone Lymphoma: What is the Oncologist To Do? Rarely, a lymphoma has features of both classical Hodgkin lymphoma and diffuse large B-cell lymphoma (DLBCL), particularly a type of DLBCL called ‘primary mediastinal B-cell lymphoma (PMBL)’. The probability of relapse-free survival, projected at 32 months, was 94% for the MACOP-B subset and 91% for the ABVD subset. It is important to highlight that diagnosis of this entity is complex and involvement, Our objective was to review clinical presentation, treatment protocol used and its efficacy and effectiveness in patients of grey zone lymphoma during last 5 years at our centre. 2005;29(11): 1411-1421. (Dunleavy K, et al., 2013; Wilson W, et al., 2014). Checkpoint inhibitors, which are cancer immunotherapies, constitute a new type of treatment for gray zone lymphoma, a rare subtype that combines the characteristics of both Hodgkin's and non-Hodgkin's forms of the disease. 01.24.18 Post Chemo.

Chronic lymphocytic leukemia/small lymphocytic lymphoma is a neoplasm composed of monomorphic small B lymphocytes in the peripheral blood, bone marrow, spleen, and lymph nodes, forming proliferation centers in tissue infiltrates (Muller-Hermelink HK, Montserrat E, Catovsky D, et al. Copyright © 2014 American Society of Hematology. In addition, they provide evidence for a novel cytogenetic pathomechanism leading to increased copy numbers of putative oncogenes from terminal chromosomal regions, most probably in the course of chromosomal stabilization by telomeric capture. All patients with bulky disease in the mediastinum at diagnosis underwent local radiotherapy after the chemotherapeutic program. This article reviews the treatment approach for mediastinal lymphomas, including CHL of the nodular sclerosis subtype (CHL-NS), PMBL, and mediastinal GZL. The average age at diagnosis is 60 years, and it is slightly more common in women than in men. Primary mediastinal (thymic) B-cell lymphoma is a high-grade non-Hodgkin's lymphoma with unique features. Hodgkin-like anaplastic large cell lymphoma ... Mediastinal cases are often referred to as mediastinal grey-zone lymphoma (MGZL) and non-mediastinal cases are grey-zone lymphoma (GZL). Introduction. Int J Hematol. We performed gene expression profiling from patients with MGZL (20), cHL (18), and PMBL (17) and show MGZL clusters between cHL and PMBL. This lymphoma is called a Gray Zone Lymphoma because it has features of both primary mediastinal large B-cell lymphoma and classical Hodgkin’s lymphoma. Grey zone lymphoma. Epub 2018 May 21. No patient died of the disease or any complication and all are well on their latest follow ups. Five-year progression-free and overall survival were 67% (95% confidence interval, 54-77) and 81% (95% confidence interval, 68-89), respectively, for all patients. At the Chicago Lymphoma Rounds on January 17, 2018, physicians from the Rush University Medical Center presented a case of gray zone lymphoma. Upon viewing this session, you will be able to: describe the presentation of patients with gray zone lymphomas (including B-cell lymphoma unclassifiable with features between BL and DLBCL, and gray zone lymphoma between PMBCL and HL) discuss the clinical and biologic features, and prognosis and therapeutic options Introduction.

However, exome sequencing in peripheral blood DNA revealed a germline mutation in TP53. There are no standardized guidelines; however, evidence strongly suggests that DLBCL-based regimens are effective in the treatment of GZL. 1. From September 1994 to July 1997, during the course of an Italian multicentric trial, 40 ALCL-HLs were randomized to receive as front-line chemotherapy MACOP-B (methotrexate with leucovorin, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin-a third-generation HG-NHL regimen) or ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine-a scheme specific for HD). 1.

Its clinical and molecular characteristics are distinct from other subtypes of DLBCL and in fact, closely resemble those of nodular sclerosing Hodgkin lymphoma (NSHL). Accounting for up to 10% of cases of DLBCL, this subtype predominantly affects females in the third and fourth decades of life. Compared with PMBL, MGZL patients were more likely to be male, express CD15, have lower expression of CD20, and have a worse outcome. Am J Hematol. Because these lymphomas are treated differently, the optimal therapy for gray zone lymphoma is unclear. 180-182). - Confirmed diagnosis of B-cell lymphoma, relapsed from or refractory to prior: - Cohort 1: B-cell lymphoma, unclassifiable, with features intermediate between. 2018; 100(5):511-517 Related Publications Introduction.

Our data confirm previous cytogenetic results from primary Hodgkin's tumors suggesting an important pathogenic role of REL and JAK2 in this disease. We analyzed biomarkers of outcome and compared their clinical and biological characteristics to PMBL. GZL is a rare lymphoma with intermediate features between classical Hodgkin lymphoma (cHL) and Diffuse Large B-cell Lymphoma (DLBCL), but cannot be classified as one or the other [Evans, 2015]. Long-term complete remission following tandem autologous stem cell transplantation and consolidative radiotherapy for refractory mediastinal gray-zone lymphoma. It affe… Further strengthening this relationship is the identification of lymphomas with clinical and morphologic features transitional between the two, known as gray zone lymphomas (GZL). Gray zone lymphoma shares features with two other types of lymphoma, classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL). It is recognized now that patients with GZL may present clinically with primary mediastinal localization or systemic disease without mediastinal involvement. The term “Gray Zone L y mphoma ” was firstly used in 1998 at the “W orkshop on Hodgkin ’ s disease and related diseases” to desig nate lymphomas at the Grant C, Dunleavy K, Eberle FC, Pittaluga, to do? Finally, continued biological and pathologic examination of this unique disease entity is warranted as well as exploration towards the integration of targeted therapeutic agents (e.g., brentuximab vedotin, programmed cell death 1inhibitors, B-cell receptor inhibitors, proteasome inhibitors, etc.) Case Report Long-term Remission by Brentuximab Vedotin for Non-mediastinal Gray Zone Lymphoma Refractory to Autologous Stem Cell Transplantation Kazutoshi Ebisawa,1 Yosuke Masamoto,1 Junji Koya,1 Arika Shimura,1 Aya Shinozaki-Ushiku,2 Kazuhiro Toyama,1 Kumi Nakazaki,1 Mineo Kurokawa1,3 Clinical Lymphoma, Myeloma & Leukemia, Vol. This disease exhibits transitional features between nodular sclerosis classical Hodgkin lymphoma (cHL) and primary mediastinal B-cell lymphoma (PMBL) [2, 3]. Though several trials have evaluated different regimens with or without radiation in PMBL and CHL-NS, there is a lack of prospective experience in treating GZL because of the rarity of these tumors. GZL is a rare lymphoma that presents with a wide spectrum of morphologies and immunohistochemical feature characteristics of both cHL and DLBCL in the same tumor tissue sample, thus necessitating extensive sampling to make the correct diagnosis [1–3].GZL often presents at an early stage with B symptoms and mediastinal mass in males aged 20-40 years [1, 2, 4, 5]. You may have a gray-zone lymphoma or primary mediastinal B-cell lymphoma, [so it’s important] to have additional markers more in the space of diffuse large B-cell lymphoma to make sure. So called “Double-hit lymphoma” (DHL) or Gray zone lymphomas are referred to mature B-cell lymphomas often bearing concurrent chromosomal rearrangement of MYC/8q24 locus in association with t(14;18)(q32;q21) translocation involving BCL2 gene at 18q21 [1,2].The t(14;18)(q32;q21) translocation can be detected in low grade FL as well as in some high grade FL and … Clinically, the initial case descriptions of GZL were primarily with mediastinal presentation; however, a nonmediastinal (systemic) clinical subtype is now recognized. Efficacy of High-Dose Therapy and Autologous Hematopoietic Cell Transplantation in Gray Zone Lymphoma: A US Multicenter Collaborative Study Biol Blood Marrow Transplant . In this case, we discuss an individual with HL in remission for over a decade, who was found to have Gray Zone Lymphoma (GZL). Mediastinal gray zone lymphoma: the missing link between classic Hodgkin’s lymphoma and mediastinal large B-cell lymphoma. We aimed at investigating the relationship between classical Hodgkin lymphoma (cHL), primary mediastinal large B‐cell lymphoma (PMBL), and gray zone lymphoma (GZL) with intermediate characteristics between cHL and PMBL, from the perspective of the aberration in programed cell death 1 and the programed death ligands (PDLs) network. Traverse-Glehen A, Pittaluga S, Gaulard P, et al. Types of MZL. Tumour lysis syndrome was not observed in any child. Mediastinal gray zone lymphoma (MGZL) shares clinical characteristics with primary mediastinal B-cell lymphoma (PMBCL) and nodular sclerosing Hodgkin lymphoma (NSHL). In retrospect, one patient most likely had a mediastinal gray zone lymphoma due to CD15 positivity and another diffuse large B cell, not otherwise specified, at pathologic review. … The term “Gray Zone L y mphoma ” was firstly used in 1998 at the “W orkshop on Hodgkin ’ s disease and related diseases” to desig nate lymphomas at the During the last few years, morphological, immunohistochemical, and genetic findings have placed anaplastic large cell lymphoma (ALCL) as a distinct clinicopathologic entity, and several reports have focused on the existence of different subtypes of the tumor. Introduction. Department of Health and Social Care written question – answered on 25th January 2018. Four Hodgkin's lymphoma cell lines (KM-H2, HDLM-2, L428, L1236) were analyzed for cytogenetic aberrations, applying multiplex fluorescence in situ hybridization, chromosome banding and comparative genomic hybridization. We performed gene expression profiling from patients with MGZL (20), cHL (18), and PMBL (17) and show MGZL clusters between cHL and … Gray Zone Lymphoma. Off of a clinical trial, we recommend R-CHOP (rituximab, cyclophosphamide, doxorubicin, oncovin, prednisolone) or dose-adjusted EPOCH-R (etoposide, prednisolone, oncovin, cyclophosphamide, doxorubicin, rituximab) for frontline treatment of GZL. Gray zone lymphoma shares features with two other types of lymphoma, classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL). With a median observation time of 34 months, 3-year event-free survival (EFS) was improved by rituximab for PMBCL (78% versus 52%, P = 0.012) and for DLBCL (81% versus 61%, P < 0.001). Chronic lymphocytic leukemia/small lymphocytic lymphoma involving the aortic valve. 2005; 29 (11):1411–1421. 2018 Oct;108(4):452-455. doi: 10.1007/s12185-018-2471-x.
