Abstract
Background and Aim Diffuse large B-cell lymphoma (DLBCL) has been classified using various parameters, including the site of origin. Studies have reported conflicting outcomes when DLBLC patients were stratified according to the site of origin. This study aimed to investigate the response rate and survival outcomes in nodal versus extranodal DLBCL and compare the results to a region-matched study covering the 1988 - 2005 period. Methods A single-center retrospective cohort study was conducted on all patients diagnosed with DLBCL and treated in a tertiary care hospital in Pakistan during 2014 - 2019. We calculated the mean and median for continuous variables and frequency and percentages for all categorical variables. Progression-free survival (PFS) and overall survival (OS) were calculated using Kaplan-Meier survival curves. A Cox proportional hazards model was used to determine the hazard ratio (HR) for OS. Results Of the 118 patients, 49 patients (41.5%) had nodal disease and 69 patients (58.5%) were diagnosed with extranodal DLBCL. The majority of patients in the nodal and extranodal cohorts presented with Stages III and IV disease (73.4% and 62.3%, respectively). A complete response to (immuno) chemotherapy was achieved in 71.4% of nodal DLBCL patients and 65.2% of extranodal DLBCL patients. The 5-year PFS and median PFS in the entire cohort were 0.8% and 17 m, respectively. The PFS and median PFS in the nodal and extranodal DLBCL cohort were 0% and 1.4%, respectively, and 15 m and 19 m, respectively. The 5-year OS and median OS in the entire cohort were 16.1% and 19 m, respectively. The OS and median OS in the nodal and extranodal DLBCL cohort were 8.2% and 21.7%, respectively, and 19 m and 21 m, respectively. Multivariable linear regression revealed that the ABC phenotype (nodal, HR = 1.37, 95% CI = 1.37 - 3.20; extranodal, HR = 1.65, 95% CI = 1.46 - 3.17; GBC as reference) and double and triple hit DLBCL (nodal, HR = 1.29, 95% CI = 1.19 - 2.81; extranodal, HR = 1.87, 95% CI = 1.28 - 2.43; and non-expressors as reference) are independent negative predictors of OS. Conclusions DLBCL incidence in the Karachi region has remained comparable but patient composition in the extranodal DLBCL cohort has shifted to predominantly advanced stage. Nodal and extranodal DLBCL were associated with similar PFS and OS profiles and first- and second-line treatment responses. Cell of origin and antigen expression status was independent negative predictors of OS, disfavoring the ABC phenotype and lesions with c-MYC and BCL2 and/or BCL6 overexpression. Relevance for Patients DLBCL is an aggressive type of non-Hodgkin's lymphoma, however; patients respond well to standard systemic chemotherapy. Extranodal type of DLBCL patients tend to have more residual disease after first-line systemic chemotherapy, but physicians should keep in mind that the subsequent line treatment mitigates its negative impact on survival.

Abstract
INTRODUCTION Leukemic involvement in high grade B cell lymphoma (L-HGBL) is rare and has been sparsely described in the literature. We report our experience in a large single institution multicenter academic setting. MATERIALS AND METHODS Medical records of patients with HGBL who received care at Mayo Clinic between 2003 and 2020 were reviewed. L-HGBL was confirmed by peripheral blood smear and flow cytometry with corroboration from tissue and bone marrow biopsy findings. RESULTS Twenty patients met inclusion criteria. All patients had significant bone marrow involvement by HGBL. Leukemic involvement presented in 11 of 20 (55%) in the de novo and 9 of 20 (45%) in the relapsed setting. Seven of 20 patients had DLBCL, NOS, 6 of 20 had transformation (t-DLBCL), 3 of 20 had transformed double/triple hit lymphoma (t-DHL/THL), 2 of 20 had double hit lymphoma (DHL), and 2 of 20 had HGBL with intermediate features between DLBCL and Burkitt lymphoma. Nine of 15 patients had MYC translocation. Based on Hans criteria, 11 of 20 had germinal center B-cell (GCB) cell of origin (COO) and 9/20 had non-GCB COO. Five of 11 de novo patients experienced CNS relapse/progression. All de novo patients received anthracycline-based chemoimmunotherapy. Eighteen of 20 patients died of progressive disease. Median overall survival was significantly better in the de novo compared to relapsed group (8.9 months vs. 2.8 months, P = .01). COO, MYC status, DHL/THL status, HGBL subtype, or treatment group did not demonstrate a significant effect on overall survival. CONCLUSION L-HGBL carries a poor prognosis and is associated with MYC translocation, DHL/THL status, transformation, and high CNS risk. Novel therapeutic approaches are needed for L-HGBL.

Abstract
High-grade B-cell lymphoma with translocations involving MYC and BCL2 or BCL6, usually referred to as double hit lymphoma (DHL), is an aggressive hematological malignance with distinct genetic features and poor clinical prognosis. Current standard chemoimmunotherapy fails to confer satisfying outcomes and few targeted therapeutics are available for the treatment against DHL. Recently, the delineating of the genetic landscape in tumors has provided insight into both biology and targeted therapies. Therefore, it is essential to understand the altered signaling pathways of DHL to develop treatment strategies with better clinical benefits. Herein, we summarized the genetic alterations in the two DHL subtypes (DHL-BCL2 and DHL-BCL6). We further elucidate their implications on cellular processes, including anti-apoptosis, epigenetic regulations, B-cell receptor signaling, and immune escape. Ongoing and potential therapeutic strategies and targeted drugs steered by these alterations were reviewed accordingly. Based on these findings, we also discuss the therapeutic vulnerabilities that coincide with these genetic changes. We believe that the understanding of the DHL studies will provide insight into this disease and capacitate the finding of more effective treatment strategies.

Abstract
Double hit lymphomas (DHL) and double expresser lymphomas (DEL) are subsets of diffuse large B cell lymphomas (DLBCL) which are being increasingly recognised as cause of treatment failure. This emphasizes the need for their separation from other DLBCL cases in order to prognosticate and administer more aggressive treatment to this set of patients. The present study was conducted with the aim to identify the DHL/DEL patients and study their distinctive clinicopathological profile and overall survival. This retrospective analysis involved 172 cases of DLBCL sub-classified on the basis of cell of origin. Immunohistochemical (IHC) analysis for MYC, BCL2, BCL6, MUM1 and CD10 was performed. Rearrangement studies were performed using break apart Fluorescent in situ hybridization. Overall survival (OS) was also evaluated. Distinctive clinical and pathological features of DHL and DEL were identified. Rearrangement study by FISH revealed seven cases of DHL (MYC + BCL2 &/or BCL6 rearrangement). Also, 20 patients (11.6%) showed a concurrent expression of BCL2 and MYC oncoproteins (DEL) on IHC. Most (6/7) DHL patients were double expressors also. The DHL patients demonstrated a significant association with female gender, high serum LDH levels (> 750 U/L) and GCB phenotype. DEL patients contrarily predominated amongst males, had intermediate LDH levels (251-500 U/L) and non GCB phenotype. The OS of the patients was 63.8% at 4 years. The OS of the DLBCL, DEL and DHL patients was 71.9%, 46.9%, and 0%, respectively at 4 years (p value 0.010). In case of DEL subtype, factors such as age < 60 years (66.7%), male sex (60.8%), nodal localization (52.5%), early disease stage (84.6%), low IPI score (60%), absence of B symptoms (50%), LDH < 250 U/L (80%) and GCB phenotype (53.3%) were associated with better OS. Further, the OS of DHL cases was 0% at 4 years. Double hit and double expresser lymphomas have poor prognostic outcomes and should be separated from DLBCL. All DELs should be tested for DHLs and especially those with immunoblastic morphology. DHL and DEL subtypes delineate the subtypes with inferior OS and reinstate the need for aggressive interventions.

Abstract
Introduction: Double hit lymphoma (DHL) represents a new diagnostic category with genetic, immunohistochemical and clinical characteristics intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma. Patients with DHL usually experience poor survival after frontline R-CHOP treatment and require alternative therapies. However, the ideal therapeutic options remain undefined. Areas covered: Traditional therapies for the treatment of DHL are discussed, including intensive induction, hematopoietic stem cell transplantation (HSCT), methotrexate CNS-directed prophylaxis, and radiation therapy. The authors further introduce small-molecule inhibitors targeting myc or bcl-2 signaling pathways, chimeric antigen receptor T-cell therapy, programmed death-1 monoclonal antibody and immunomodulatory drugs as novel approaches. Expert opinion: No standard treatment exists for DHL. At present, DA-EPOCH-R exhibits an upfront induction option. Central nervous system prophylaxis with methotrexate is recommended as part of the induction therapy. For those who do not obtain complete remission, HSCT or clinical trials should be considered. Targeted approaches, especially chimeric antigen receptor T-cell therapies and small-molecule inhibitors targeting myc or bcl-2, exhibit the potential of improving outcomes for patients with DHL. High-throughput sequencing is a promising technique both at diagnosis and relapse, in order to predict outcomes and potential novel therapies.

Abstract
OPINION STATEMENT The 2016 revision of the WHO classification of lymphoid neoplasms includes new entities along with a clearer definition of provisional and definitive subtypes based on better understanding of the molecular drivers of lymphomas. These changes impact current treatment paradigms and provide a framework for future clinical trials. Additionally, this update recognizes several premalignant or predominantly indolent entities and underscores the importance of avoiding unnecessarily aggressive treatment in the latter subsets.

Abstract
Diffuse large B-cell lymphoma (DLBCL) is one of the most common causes of non-Hodgkin’s lymphoma (NHL). Some of these DLBCLs can have genetic mutations as well as protein overexpression. The genes involved are MYC, BCL-2 and BCL-6. These are very aggressive and do not respond well to standard chemotherapy regiment. Lymphomas usually show classic signs and symptoms but rarely can present with little or no symptoms or even mimic other disease processes. Here we will present a case where a spinal lymphoma mimicked a hematoma and the patient developed signs and symptoms only after mechanical fall and hitting his back.

Abstract
INTRODUCTION The designation high-grade B-cell lymphoma (HGBL) has been incorporated into the 2016 Revision of the WHO classification of lymphoid neoplasms and includes two types: (1) HGBL, not otherwise specified; and (2) HGBL with MYC and BCL2 and/or BCL6 rearrangements, also known as double or triple hit lymphoma (DHL/THL). These categories of lymphomas represent 1-2% of non-Hodgkin lymphomas and a considerable portion of DLBCL patients who are primary refractory to R-CHOP therapy. It corresponds to the designation 'B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and Burkitt lymphoma' in the 2008 WHO classification. Areas covered: This paper provides an update of HGBL, focusing on their pathologic features, prognosis, and diagnostic workup. It highlights advances in our understanding of DHL/THL. Expert commentary: The diagnosis relies on FISH testing and the major controversial question is when to perform it to diagnose virtually all DHL/THL cases, but also being cost effective. Currently there is no consensus. Considering the high refractory rate of these patients to standard R-CHOP induction, the authors recommend FISH testing in all newly diagnosed large B-cell lymphoma by using our stepwise test strategy. With the progress of molecular genetics, the prognosis will be further stratified and HGBL-NOS maybe further evolve too.

Abstract
High grade B-cell lymphoma (HGBCL) by WHO 2016 classification requires rearrangements of MYC and BCL2 and/or BCL6, practically covering the so called "double-hit" or "triple hit" lymphomas. We report a case of HGBCL "triple-hit" lymphoma in a 64-year old female. Cytogenetic and fluorescence in situ hybridization (FISH) studies revealed complex karyotype including rearrangement of MYC to a novel, non-IG partner on chromosome 18, and rearrangement of BCL2, BCL6 and IGH as well as ins(3)(q21q27.3q25.1) among other abnormalities. FISH studies showed five copies of MYC and 3-8 copies of BCL2. Gene expression analysis by RNA sequencing showed that MYC, BCL2 and MECOM genes were overexpressed whereas BCL6 was under-expressed. BCL6 was fused to MBNL1 gene due to complex structural rearrangement. MYC was expressed in >70% of cells and BCL2 was diffusely but highly expressed by immunohistochemistry. No pathogenic mutations were identified by sequencing a 26-gene panel including TP53. The patient has unexpectedly been in complete remission for 12 months after diagnosis after intensive chemotherapy including DA-EPOCH regimen despite having HGBCL. The prognostication of HGBCL patients may further be improved by the sub-categorization of these lymphomas on the basis of more detailed genomic markers than merely the WHO 2016 classification.

Abstract
High-grade B cell lymphoma with MYC and BCL2 rearrangements (double hit) has a poor prognosis with standard R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone). We report here a treatment algorithm of DA-EPOCH-R (dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, rituximab) followed by BEAM (carmustine, etoposide, cytarabine, melphalan) autologous transplant in 36 cases of previously untreated double hit lymphoma (DHL) from 2010 to 2015. A high risk International Prognostic Index (IPI) was present in 42% of cases. At median follow-up of 38 months, the 2-year progression free survival (PFS) and overall survival (OS) were 69% (95% CI 54-84%) and 71% (95% CI 56-86%). Eight cases were refractory to induction with 1-year OS 20%, and no factors were predictive for primary refractory disease. Of 28 responders, 17 proceeded to transplant while 11 were observed, primarily due to age and co-morbidities. By 24-week landmark analysis after diagnosis, the 2-year PFS and OS were both 94% (95% CI 83-100%) vs 79% (95% CI 52-100%) for transplant vs observation (p = .59 for both PFS and OS). There was no significant benefit to consolidative transplant in our series, and primary refractory DHL needs novel approaches.

Abstract
B cells lymphoma is one of the most challenging extra-hepatic manifestations of hepatitis C virus (HCV). Recently, a new kind of B-cell lymphoma, named double-hit B (DHL), was characterized with an aggressive clinical course whereas a potential association with HCV was not investigated. The new antiviral direct agents (DAAs) against HCV are effective and curative in the majority of HCV infections. We report the first case, to our knowledge, of DHL and HCV-infection successfully treated by new DAAs. According to our experience, a DHL must be suspected in case of HCV-related lymphoma, and an early diagnosis could direct towards a different hematological management because a worse prognosis might be expected. A possible effect of DAAs on DHL regression should be investigated, but eradicating HCV would avoid life-threatening reactivation of viral hepatitis during pharmacological immunosuppression in onco-haematological diseases.

Abstract
Diffuse large B-cell lymphomas with aberrations in MYC, BCL2 and/or BCL6 by genetic alterations or protein expression represent a group of high grade B-cell lymphomas with inferior outcomes when treated with standard RCHOP chemotherapy. As a result, intensified induction regimens have been suggested in an effort to improve outcomes. Conclusions to date have largely been drawn from retrospective data although prospective data is slowly starting to emerge. Chemoimmunotherapy refractoriness is problematic and relapse rates are high. Patients with double hit lymphoma appear to have increased risk of CNS involvement and prophylaxis is recommended. There is insufficient evidence available to date to strongly recommend for or against consolidative stem cell transplant in this population. Collaborative clinical trials will be needed to establish a preferred therapeutic regimen and an appropriate standard of care in this unique group of patients with DLBCL.

Abstract
A cohort comprising 156 patients with B-cell neoplasms harboring an MYC rearrangement was analyzed with respect to phenotypic presentation, molecular markers (TP53, MYC and ID3) and additional cytogenetic abnormalities (concomitantly occurring BCL2, BCL6 and/or CCND1 rearrangements; double, triple or quadruple hit lymphomas = multiple hit lymphomas). MYC translocations occurred as single hit (only MYC rearranged, 63%) or multiple hit lymphoma (37%) and presented as acute leukemia (AL) (14%), Burkitt lymphoma (30%), chronic lymphocytic leukemia (CLL) (21%) or other mature B-cell neoplasms (35%). Multiple hit lymphomas more frequently showed a complex karyotype compared to single hit lymphomas (62% vs. 28%, p < 0.001). Single hit Burkitt lymphomas presented with specific characteristics, by translocation of MYC to an immunoglobulin locus, predominantly a non-complex karyotype (23% vs. 67%, p = 0.012) and a significantly higher ID3 and TP53 mutation frequency (ID3mut: 49% vs. 0%, p = 0.002; TP53mut: 69% vs. 33%, p = 0.045). Additionally, MYC rearranged CLL presented as outstanding group by often showing a non-complex karyotype (85%), absence of ID3 mutations, a high frequency of SF3B1 mutations, and a frequent involvement of non-immunoglobulin loci as MYC-partner genes (61%). Consequently, genetic characteristics distinguish different subgroups of MYC rearranged B-cell neoplasms and therefore may contribute to a new classification system.

Abstract
Double-hit lymphomas (DHL) are defined as B-cell lymphoma with a chromosomal breakpoint affecting the MYC/8q24 locus in combination with rearrangement at (14;18)(q32;q21). We recently observed three cases of B-cell lymphoma with an extra intact MYC signal in association with the t(14;18)(q32;q21) translocation. The impact of an extra copy of MYC to the clinical course and prognosis of one patient with Diffuse Large B Cell Lymphoma (DLBCL) and two patients with Follicular Lymphoma (FL) was evaluated. Flow cytometry in all cases demonstrated lambda- or kappa-light chain restricted CD20 and CD10 positive neoplastic B cells. FISH analysis was negative for MYC gene rearrangement but demonstrated an extra copy of intact MYC. Tissue sections displayed typical starry sky "gray zone" lymphoma morphology in case of DLBCL and FL morphology in cases 2 and 3, with high Ki67 labeling in all three cases. All patients responded well to initial chemotherapy although displayed variant outcome after initial remission. The patient with DLBCL deceased within a year of diagnosis while the other two patients with FL showed much better overall survival. Our limited experience showed that additional copy of intact MYC may be equivalent to "classic" DHL on the background of DLBCL with additional cytogenetic abnormalities, however isolated t(14;18)(q32;q21) translocation in combination with additional copy of intact MYC may demonstrate histology and clinical outcome more comparable with "classic" low grade follicular lymphoma, albeit with more aggressive morphology.

Abstract
Approximately 30% of patients with follicular lymphoma (FL) transform to a more aggressive malignancy, most commonly diffuse large B cell lymphoma. Rarely, FL transformation results in clinical findings, histology, and immunophenotype reminiscent of B-lymphoblastic leukemia/lymphoma. We report the largest series to date with detailed analysis of 7 such patients. Lymphoblastic transformation occurred on average 2 years after initial diagnosis of FL. Five patients had prior intensive chemotherapy. Two patients developed mature high-grade lymphoma, followed by the lymphoblastic transformation. FL had BCL2 gene rearrangement in 4 of 5 cases. High-grade transformation was accompanied by MYC gene rearrangement (5 of 5). Transformation was characterized by expression of TdT, loss of Bcl6, variable loss of immunoglobulin light chain, and persistence of Pax-5, Bcl2, and CD10. Whole-exome sequencing in 1 case revealed presence of several actionable mutations (CD79B, CCND3, CDK12). FL, aggressive mature B cell lymphoma, and lymphoblastic transformation were clonally related in 6 evaluable cases. After transformation, survival ranged from 1 to 14 months. Four patients died of disease, 2 were in remission after stem cell transplant, and 1 was alive with disease.

Abstract
MYC is one of the most frequently deregulated oncogenes in human malignancies. It encodes a leucine zipper transcription factor that modulates a broad spectrum of cellular genes responsible for enhancing cell proliferation, cellular metabolism, growth, angiogenesis, metastasis, genomic instability, stem cell self-renewal and reduced differentiation. MYC functions predominantly as an amplifier of expression of already active genes, potentiating the pre-existing transcriptional program, although it can also repress certain transcriptional targets. In mouse models, MYC induces lymphomas, but requires cooperation with other lesions, including inactivation of the p53 pathway, structural alterations of BCL2 family members, or increased PI3K activity. In human B-cell tumors, MYC rearrangements involving the 8q24 region and immunoglobulin heavy or light genes are a hallmark of Burkitt lymphoma (BL), but can also occur in other lymphoid malignancies, that include diffuse large B-cell lymphoma (DLBCL), B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and Burkitt lymphoma (BCLU), plasma cell myeloma (PCM), mantle cell lymphoma (MCL) and plasmablastic lymphoma. For non-BL lymphoid malignancies, MYC fusions represent secondary genetic events and exist in the context of complex karyotypes. Regardless of the mechanism deregulating MYC, lymphomas over-expressing MYC are addicted to this oncogene, highlighting the potential clinical utility of MYC targeting strategies. Several promising approaches for pharmaceutical intervention have been suggested which are now in preclinical or clinical development. Herein, we therefore review the molecular pathogenetic mechanisms associated with MYC deregulation in human B-cell lymphomas and their implications for therapies targeting MYC.

Abstract
A 50-year-old woman who presented with a mass in the thyroid gland was diagnosed as having diffuse large B-cell lymphoma (DLBCL) by biopsy in August 2011. The tumor had a complex chromosomal karyotype, including 8q24 (C-MYC) and 18q21(BCL-2), and fluorescence in situ hybridization confirmed split signals of C-MYC and BCL-2. BCL-2/IgH and C-MYC/IgH fusion signals were also observed. Three courses of rituximab, cyclophosphamide, doxorubicin, vincristine, prednisolone (R-CHOP) therapy were given, followed by thyroid gland irradiation. She was achieved complete remission (CR). In January 2012, a mass appeared in the right breast, which was diagnosed as relapse by biopsy. CR was achieved again after the 4th course of R-CHOP therapy, and one course of rituximab, etoposide, methylprednisolone, cytarabine, cisplatin (R-ESHAP) therapy was given. Thereafter, CR has been maintained after high-dose chemotherapy and autologous peripheral blood stem cell transplantation. There have been only 3 reported cases of primary thyroid C-MYC and BCL-2 double-hit lymphoma, including the present case; 2 of the cases were cases of DLBCL. R-CHOP therapy, irradiation and autologous peripheral blood stem cell transplantation are expected to be effective for such patients.
