Abstract
OBJECTIVE Primary extranodal non-Hodgkin's lymphoma (PE-NHL) of the head and neck is the second common site of extranodal lymphoma, accounting for approximately one-third of all extranodal non-Hodgkin's lymphoma (E-NHL). However, in recent years, large-scale PE-NHL case studies in China and worldwide are rare and not comprehensive enough. This work analyzed the clinical manifestations, pathological features, immunophenotypes and diagnosis of PE-NHL, as well as the factors affecting the treatment and prognosis. METHODS A retrospective study was performed on 74 patients who were diagnosed with head and neck PE-NHL and treated for the first time. The clinical manifestations, pathological features, and immunophenotypes were summarized, and the factors related to the treatment and prognosis were analyzed. RESULTS The most common site of this disease was the Waldeyer's ring, followed by the nasal cavity. Diffuse large B-cell lymphoma was the most common type, followed by extranodal NK T-cell lymphoma nasal type. The 1-year, 2-year, and 5-year progression-free survival (PFS) rates were 76.4%, 67.9%, and 59.3%. The 1-year, 2-year, and 5-year overall survival (OS) rates were 89.4%, 85.6%, and 63.2%. ECOG score ≥ 2, Ann Arbor stage III or IV and IPI risk stratification identifying patients as the high-risk group were independent risk factors affecting the OS of patients with PE-NHL of the head and neck. CONCLUSIONS The most common site of PE-NHL in these Chinese patients was the Waldeyer's ring, but the incidence in the nasal cavity was higher than that reported in Western countries. Radiotherapy combined with chemotherapy had better efficacy than chemotherapy alone, and the prognosis depended on the ECOG score and clinical stage. IPI had a better prognostic value in patients in the high-risk group of head and neck PE-NHL.

Abstract
Purpose The pharmacology, pharmacokinetics, pharmacodynamics, clinical efficacy, and safety of zanbrutinib are described. Summary Mantle cell lymphoma (MCL) is a mature B-cell lymphoma that is typically associated with unfavorable outcomes, and virtually all patients with MCL have refractory or relapsed disease despite aggressive treatment. The treatment paradigm for MCL has transformed dramatically over the past decade owing to rapid advancements in immunotherapy and molecular-targeted therapies. Zanubrutinib, a second-generation Bruton's tyrosine kinase inhibitor (BTKI) designated for mature B-cell non-Hodgkin's lymphoma (NHL), has drastically improved the survival outcomes in relapsed/refractory (R/R) MCL patients. This selective BTKI is a small molecule that functions by forming a covalent bond in the active site of BTK. The inhibition of BTK activity is essential for the signaling of B-cell antigen receptor (BCR) and cytokine receptor pathways. In a preclinical study, zanubrutinib inhibited malignant B-cell proliferation and reduced tumor growth. Zanubrutinib was granted FDA-accelerated approval based on the results of Phase I and II trials. The investigator-assessed overall response rate was 83.7%, of which 78% of patients achieved complete response. The median duration of response was 19.5 months, and the median progression-free survival was 22.1 months. The most common (≥20%) all-grade adverse events were low neutrophil count (46.5%), upper respiratory tract infection (38.4%), rash (36.0%), low white blood cell count (33.7%), and low platelet count (32.6%). Conclusion Zanubrutinib is a selective, next-generation, orally active, irreversible BTK inhibitor. The selectivity of zanubrutinib and its superior efficacy, with a well-tolerated safety profile, have proven to be attractive options for other malignancies.

Abstract
This report describes the case of a 73-year-old female patient who presented with abdominal symptoms. A colonoscopy identified a cecal mass confirmed as mantle cell lymphoma (MCL). Imaging showed extensive lymph node involvement. The patient received rituximab, cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisone (R-CHOP) chemotherapy, resulting in tumor reduction and adenopathy resolution. Despite a typically unfavorable prognosis associated with a high Ki-67 index, the patient responded well to chemotherapy and achieved a favorable outcome. This case highlights the importance of early detection, appropriate treatment which in our case was R-CHOP, and personalized management approaches in addressing MCL.

Abstract
The field of mantle cell lymphoma (MCL) has witnessed remarkable progress due to relentless advances in molecular pathogenesis, prognostication, and newer treatments. MCL consists of a spectrum of clinical subtypes. Rarely, atypical cyclin D1-negative MCL and in situ MCL neoplasia are identified. Prognostication of MCL is further refined by identifying somatic mutations (such as TP53, NSD2, KMT2D), methylation status, chromatin organization pattern, SOX-11 expression, minimal residual disease (MRD), and genomic clusters. Lymphoid tissue microenvironment studies demonstrated the role of B-cell receptor signaling, nuclear factor kappa B (NF-kB), colony-stimulating factor (CSF)-1, the CD70-SOX-11 axis. Molecular mechanism of resistance, mutation dynamics, and pathogenic pathways (B-cell receptor (BCR), oxidative phosphorylation, and MYC) were identified in mediating resistance to various treatments (bruton tyrosine kinase (BTK) inhibitors [ibrutinib, acalabrutinib]. Treatment options range from conventional chemoimmunotherapy and stem cell transplantation (SCT) to targeted therapies against BTK (covalent and noncovalent), Bcl2, ROR1, cellular therapy such as anti-CD19 chimeric antigen receptor therapy (CAR-T), and most recently bispecific antibodies against CD19 and CD20. MCL patients frequently relapse. Complex pathogenesis and the management of patients with progression after treatment with BTK/Bcl2 inhibitors and CAR-T (triple-resistant MCL) remain a challenge. Next-generation clinical trials incorporating newer agents and concurrent translational and molecular investigations are ongoing.

Abstract
Chromosomal translocations arising from aberrant repair of multiple DNA double-strand breaks (DSBs) are a defining characteristic of many cancers. DSBs are an essential part of physiological processes in antibody-producing B cells. The B cell environment is poised to generate genome instability leading to translocations relevant to the pathology of blood cancers. These are a diverse set of cancers, but limited data from under-represented groups have pointed to health disparities associated with each. We focus on the DSBs that occur in developing B cells and propose the most likely mechanism behind the formation of translocations. We also highlight specific cancers in which these rearrangements occur and address the growing concern of health disparities associated with them.

Abstract
Mantle cell lymphoma is typically an aggressive, rare form of non-Hodgkin lymphoma that arises from cells originating in the “mantle zone.” Here, we describe a case of mantle cell lymphoma associated with gastrointestinal bleeding, which was worked up as a possible gastrointestinal lesion or intraluminal pathology. The patient presented with symptomatic microcytic anemia associated with a positive guaiac fecal test. However, after an extensive workup to elucidate the symptomatic anemia’s etiology, mantle cell lymphoma associated with a positive guaiac test was the culprit. Usually, mantle cell lymphoma is diagnosed at a later stage involving the bone marrow and gastrointestinal tract.

Abstract
OBJECTIVES To describe disease characteristics and treatment and to analyze survival and mortality for extranodal mantle cell lymphoma (MCL) of the head and neck. METHODS Patients with extranodal MCL-excluding primary sites in the salivary glands, eye, and adnexa-were identified from the Surveillance, Epidemiology, and End Results (SEER) 18 Registries (2000-2015). Overall survival (OS) and cumulative incidence of MCL and non-MCL mortality were calculated. Factors associated with MCL and non-MCL mortality were analyzed with cause-specific hazard models. RESULTS Five hundred nine patients met criteria for descriptive analysis and 294 patients met criteria for survival analysis, with a median follow-up of 58 months. The most common sites for MCL were the oropharynx (66.0%), nasopharynx (19.1%), and oral cavity (8.4%). The most common treatment received was chemotherapy alone (48.9%), followed by chemoradiation therapy (16.9%), and radiation therapy alone (10.4%). The proportion of cases diagnosed as early-stage disease ranged from 31% of sinonasal MCLs to 83% of laryngeal MCLs. At 5 years, OS was 63% (95% CI: 57%-69%). There was no significant difference in OS (P = .79), cumulative incidence of MCL mortality (P = .76), or cumulative incidence of non-MCL mortality (P = .98) by anatomic site. Comparing early-stage to late-stage disease, there was no significant difference in OS (P = .38), cumulative incidence of MCL mortality (P = .07), or cumulative incidence of non-MCL mortality (P = .14). Multivariate analysis showed increased hazard of MCL mortality for patients that were older or that presented with stage III or stage IV disease. CONCLUSION The oropharynx is the most common subsite of head and neck MCLs, followed by the nasopharynx. Primary head and neck MCLs appear to present at an earlier stage than MCLs of other regions. In particular, laryngeal and hypopharyngeal MCLs may present as stage I or II disease.

Abstract
Introduction: The therapeutic options for mantle cell lymphoma (MCL) include traditional chemo-immunotherapy for newly diagnosed cases, and targeted treatments including the bruton tyrosine kinase inhibitors in the relapsed/refractory (R/R) disease setting. The advent of commercially available chimeric antigen receptor (CAR) T-cell therapy in the last three years has dramatically improved the outcomes of patients with R/R large B-cell lymphoma.Areas covered: This review is an in-depth evaluation and appraisal of brexucabtagene autoleucel (brexu-cel), the first anti-CD19 CAR T-cell therapy to be approved for patients with R/R MCL, after the results of a Phase II (ZUMA-2) trial.Expert opinion: In the absence of head-to-head comparison studies with Btk inhibitors, up-front use of brexu-cel in patients with high-risk MCL and poor prognostic features may be advantageous, possibly even before exposure to Btk inhibitor, and further study of this approach is warranted. While data on long-term outcomes of CAR T-cell therapy in MCL patients are needed, brexu-cel has shown remarkable clinical activity and its regulatory approval has immediate practice-changing implications in this highly aggressive malignancy.

Abstract
Purpose: The treatment paradigm for mantle cell lymphoma (MCL), a B-cell malignancy, has shifted considerably during the past decades. This study aimed to evaluate time trends in overall survival (OS) and disease-specific mortality (DSM) of younger (age ≤ 65 years) patients with MCL from 1995 to 2016. Methods: We used the Surveillance, Epidemiology, and End Results database. Year of diagnosis was divided into three eras: the chemotherapy-alone era (1995–2000), intensified-immunochemotherapy era (2001–2012), and targeted-therapy era (2013–2016). We used the Kaplan–Meier method, log-rank test, and subdistribution proportional hazard regression in the analysis. Results: A total 4,892 patients were identified. Median OS increased from 67 months in the chemotherapy-alone era to 107 months in the intensified-immunochemotherapy era (P < 0.001). The DSM rate decreased significantly from 1995 to 2016 (P < 0.001); the adjusted hazard ratios of MCL-specific death were 0.589 (P < 0.001) for the intensified-immunochemotherapy era and 0.459 (P < 0.001) for targeted-therapy era, as compared with the chemotherapy-alone era. Patients with advanced-stage MCL exhibited lowering risk of death across the three eras (P < 0.001). Conclusions: During 1995–2016, survival in younger patients with MCL increased significantly, especially those with advanced-stage disease, potentially reflecting the impact of advancement in treatment modalities on MCL outcome.

Abstract
Background: Mantle cell lymphoma (MCL), a rare and aggressive disease, accounts for approximately 5% of all B-cell non-Hodgkin's lymphomas. Evidence on the burden of this disease, for patients and healthcare providers, is scarce.Methods: Four systematic literature reviews were developed to identify epidemiological, real-world clinical, economic and humanistic burden data on patients with MCL. Electronic databases searched included MEDLINE and Embase, NHS EED and Econlit.Results: Eight epidemiological studies, 19 clinical burden, 2 economic impact and 0 quality of life studies were identified. The range of standardized MCL incidence rates was 0.1-1.27/100,000. Overall survival rates of patients at 3 years differed by age at diagnosis (≤65 years: 76-81%, >65 years: 46-64%) and disease stage (stage I: 73-80%, stage IV: 48-53%). Outcomes were poorer in previously treated patients, and those with later stage or blastoid disease, and improved with more recent diagnosis/treatment. Hospitalization is a major contributor to healthcare cost and differs by therapy toxicity.Conclusions: We identified significant data gaps for many G20 countries for epidemiology, real-world clinical, economic and humanistic burden. These literature reviews demonstrate the ongoing unmet need for MCL patients globally. Future research to further understand the real-world impact of MCL is needed along with new therapeutic options to improve patient outcomes.

Abstract
Intrahepatic cholangiocarcinoma (ICC) is an aggressive malignancy with poor prognosis and increasing incidence. Due to its asymptomatic manifestation, ICC often progresses to a metastatic stage on diagnosis. The current study attempted to evaluate the prognostic value of site-specific metastases in patients with metastatic ICC.Surveillance, Epidemiology, and End Results (SEER) database (2010-2015) was queried and metastatic ICC patients were classified according to the metastatic sites. Kaplan-Meier analysis was used for survival comparisons and multivariate analysis was performed to elicit characteristics independently associated with survival.A total of 1567 patients were identified and included in the analysis. Compared with those with multiple-site metastases, patients with single-site metastases had better prognostic outcomes. Among the single-site metastases, regional lymph nodes metastases had the best prognosis; liver metastases had better prognostic outcomes than bone metastases; no significant difference was found between lung and bone or liver metastasis. Local treatment of primary tumor might benefit patients with isolated lymph nodes metastases and few exceptional cases of patients with liver metastases.Different metastatic sites have distinct impact on the survival outcomes of patients with advanced ICC and highly selected subset of them might benefit from the local treatment of the primary tumor.

Abstract
Unprecedented advances in our understanding of the pathobiology, prognostication, and therapeutic options in mantle cell lymphoma (MCL) have taken place in the last few years. Heterogeneity in the clinical course of MCL-indolent vs aggressive-is further delineated by a correlation with the mutational status of the variable region of immunoglobulin heavy chain, methylation status, and SOX-11 expression. Cyclin-D1 negative MCL, in situ MCL neoplasia, and impact of the karyotype on prognosis are distinguished. Apart from Ki-67% and morphology pattern (classic vs blastoid/pleomorphic), the proliferation gene signature has helped to further refine prognostication. Studies focusing on mutational dynamics and clonal evolution on Bruton's tyrosine kinase (BTK) inhibitors (ibrutinib, acalabrutinib) and/or Bcl2 antagonists (venetoclax) have further clarified the prognostic impact of somatic mutations in TP53, BIRC3, CDKN2A, MAP3K14, NOTCH2, NSD2, and SMARCA4 genes. In therapy, long-term follow-up on chemo-immunotherapy studies has demonstrated durable remissions in some patients; however, long-term toxicities, especially from second cancers, are a serious concern with chemotherapy. The therapeutic options in MCL are constantly evolving, with dramatic responses from nonchemotherapeutic agents (ibrutinib, acalabrutinib, and venetoclax). Chimeric antigen receptor therapy and combinations of nonchemotherapeutic agents are actively being studied and our focus is shifting toward making the treatment of MCL chemotherapy-free. Still, MCL remains incurable. The following aspects of MCL continue to pose a challenge: disease transformation, role of the cytokine-microenvironmental milieu, incorporation of positron emission tomography-computerized tomography imaging, minimal residual disease in the prognosis, circulating tumor DNA testing for clonal evolution, predicting resistance to BTK inhibitors, and optimal management of patients who progress on BTK/Bcl2 inhibitors. Next-generation clinical trials should incorporate nonchemotherapeutic agents and personalize the treatment based upon the genomic profile of individual patient. Recent advances in the field of MCL are reviewed.

[PMID: 31029647 DOI: 10.1016/j.clml.2019.03.006] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2018] [Revised: 02/21/2019] [Accepted: 03/03/2019] [Indexed: 12/20/2022]
Abstract
BACKGROUND Although race and socioeconomic factors are associated with outcome in many malignancies, few studies have examined the effect of race and socioeconomic status on patients with mantle cell lymphoma (MCL). PATIENTS AND METHODS We used the National Cancer Database to identify patients with MCL diagnosed between 2004 and 2013. We used χ2 and analysis of variance to assess associations of covariates with race/ethnicity. For univariate and multivariable analyses of overall survival (OS) we used Cox proportional hazards models. OS from the time of diagnosis was the primary end point. RESULTS Of 18,120 MCL patients, 14,984 (83%) were white non-Hispanic (NH), 709 (4%) black NH, and 1096 (6%) Hispanic. Of these patients, 6798 (39%) had private insurance, 9520 (55%) Medicare, and 635 (4%) Medicaid. Compared with white NH race, black race was associated with treatment at an academic/research program (347 of 681 patients [51%] vs. 5577 of 14,851 [38%]), B symptoms (196 patients [28%] vs. 3 [25%]), Medicaid/uninsured status (101 patients [15%] vs. 642 [5%]), and residence in regions with lower average education and income (all P < .001). Compared with NH black and Hispanic patients, more white NH patients received stem cell transplantation (73 patients [10%] vs. 114 [10%] vs. 1891 [13%]; P < .001). In multivariable analysis, Hispanic ethnicity, private insurance, and treatment at an academic center were associated with better OS (5-year OS 55.8%, 66.2%, and 56.6%, respectively), whereas black race was associated with inferior OS (5-year OS 46.8%). CONCLUSION We identified disparities according to race and ethnicity in OS, independent of insurance and socioeconomic status. Further assessment of treatment patterns might elucidate new targets for improving access to care and health outcomes for rare cancers.

Abstract
Multiple myeloma (MM) is two- to three-fold more common in African Americans (AAs) compared to European Americans (EAs). This striking disparity, one of the highest of any cancer, may be due to underlying genetic predisposition between these groups. There are multiple unique cytogenetic subtypes of MM, and it is likely that the disparity is associated with only certain subtypes. Previous efforts to understand this disparity have relied on self-reported race rather than genetic ancestry, which may result in bias. To mitigate these difficulties, we studied 881 patients with monoclonal gammopathies who had undergone uniform testing to identify primary cytogenetic abnormalities. DNA from bone marrow samples was genotyped on the Precision Medicine Research Array and biogeographical ancestry was quantitatively assessed using the Geographic Population Structure Origins tool. The probability of having one of three specific subtypes, namely t(11;14), t(14;16), or t(14;20) was significantly higher in the 120 individuals with highest African ancestry (≥80%) compared with the 235 individuals with lowest African ancestry (<0.1%) (51% vs. 33%, respectively, p value = 0.008). Using quantitatively measured African ancestry, we demonstrate a major proportion of the racial disparity in MM is driven by disparity in the occurrence of the t(11;14), t(14;16), and t(14;20) types of MM.

Abstract
Urinary bladder cancer (UBC) has a high incidence rates in many southern and eastern European countries, in parts of Africa and the Middle East, and in North America. It exhibits a wide variety of histological types that goes from less aggressive to rapid-growing ones. In order to compare the different presentations, etiologies, and prognoses among racial groups, including NHW (non-Hispanic white), HW (Hispanic white), blacks, and API (Asian and Pacific Islander), we analyzed the UBC patients diagnosed between 1973 and 2014 using SEER (Surveillance, Epidemiology, and End Results) database. Patient characteristics, age-adjusted incidence rates, and survival were compared across races. There are significant racial differences in patients' characteristics, including gender, marital status, age at diagnosis, treatment strategies, grade, stage, survival time, and so on. Overall, non-Hispanic whites have the highest incidence rate, followed by blacks, Hispanic whites, and APIs. In the analysis of survival, significant racial differences exist when stratified by gender, age group, histological type, stage, location and treatment strategies. Racial differences exist among UBC patients in the United States in terms of characteristics, incidence, and survival. Future studies may collect and analyze more data for comprehensive description and interpretation of the racial differences.

Abstract
Background Few studies have assessed mantle cell lymphoma (MCL) incidence trends in the U.S. National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) areas. Previous studies were 5 to 9 years old and MCL incidence in Texas remains unknown. This study updated the temporal trends and variations of MCL incidence in the SEER areas and compared them with counterpart data in Texas. Results From 1995 to 2013, there were 2, 435 and 5, 193 newly diagnosed MCL patients in Texas and SEER areas. Age-adjusted MCL incidence was 0.91 per 100,000 persons per year in Texas and 1.01 in SEER areas. MCL incidence increased steadily with an annual percent change (APC) of 2.56% in SEER areas and an APC of 2.16% in Texas. In SEER areas, APCs for MCL incidence were significantly different from zero in patients with advanced stage tumor (3.33%), male (2.71%), elderly patients ≥ 80 years old (4.21%) and non-Hispanic white patients (2.83%) (all P < 0.05). Similar patterns were found in Texas for both incidence rates and APCs. Materials and methods We identified all adult patients with newly diagnosed MCL in Texas Cancer Registry and SEER databases from 1995 to 2013. Age-adjusted incidence rates were calculated and negative binomial regression model was used to assess the factors associated with MCL incidence. Conclusions MCL incidence rates increased over time in both Texas and SEER areas, with increases being greater in male, non-Hispanic white, and elderly patient ≥70 years with advanced stage tumors. Texas has similar MCL incidence trends and disparities as the national SEER areas.

Abstract
The aim of this study is to investigate the incidence and clinical outcomes of primary mediastinal large B-cell lymphoma (PMBL).Here we did a retrospective analysis using the surveillance, epidemiology, and end results (SEER) database to analyze the incidences and survival of patients with PMBL diagnosed during 2001-2012 among major ethnic groups.During 2001-2012, a total of 426 PMBL patients were identified, including 336 whites, 46 blacks, and 44 others. The incidence rates of female to male ratios in white, black, and other were 1.4938, 1.1202, and 1.7303 respectively, suggesting that the female-prominent disease occurrence was seen only in whites and others, but not in black population. Compared to white, the other had a worse 5-year overall survival (OS); however, factors including age, race, socioeconomic status, and stage associated with OS showed no significant difference among ethnic groups; thus, biology factors should be explored to explain the racial difference in OS.In conclusion, our findings revealed diversities in demographic features and prognosis among different racial groups.

Abstract
We evaluated the association of baseline prognostic factors with conditional net survival among survivors of six subtypes non-Hodgkin lymphoma using the SEER program data from 2000-2012. Among 2-year survivors, further prognosis markedly improved in Burkitt's (BL) and diffuse large B-cell lymphoma (DLBCL), and became the same as for follicular lymphoma (5-year net survival ≥ 85%). Mantle cell lymphoma (MCL) demonstrated the worst prognosis of all studied histologies up to 5 years of survivorship. Age and stage lost prognostic significance in BL within 2 years from diagnosis. Racial disparities in net survival disappeared within 2 years for all subtypes, except in chronic lymphocytic leukemia, where black patients had persistently worse prognosis, and in MCL, where they had unexpectedly better prognosis than other races after 2 years. Many baseline factors may lose their initial prognostic value for lymphoma survivors, which should be considered when counseling patients about their prognosis and long-term surveillance.

Abstract
Mantle cell lymphoma (MCL) is an incurable, typically aggressive subtype of non-Hodgkin lymphoma, accounting for 4%–7% of newly diagnosed non-Hodgkin lymphoma cases. Chemoresistance commonly ensues in MCL, and patients with this heterogeneous disease invariably relapse, underscoring the unmet need for better therapies. Over the past few years, several novel agents with promising activity and unique mechanisms of action have been deemed effective in MCL. Bortezomib is a reversible proteasome inhibitor, approved as a single agent for patients with relapsed/refractory MCL who have received at least one prior line of therapy. Addition of bortezomib to chemoimmunotherapies has demonstrated good tolerability and superior efficacy, both in the upfront and salvage settings, and recently one such combination of bortezomib plus rituximab, cyclophosphamide, doxorubicin, and prednisone was approved as a frontline regimen in untreated patients with MCL. This review examines the role of bortezomib in a multitude of clinical settings and ongoing clinical trials designed to optimize its integration in the current treatment paradigms of MCL.
