    2010-01-01

    Introduction Non-Hodgkin’s lymphoma (NHL) is the sixth most common cancer in the UK; 9443 new cases were diagnosed in the UK in 2002, and it caused 4418 UK deaths in 2003. Incidence rates show distinct geographical variation, with age-standardised incidence rates ranging from 17 per 100,000 in northern America to 4 per 100,000 in south-central Asia. NHL occurs more commonly in males than in females, and the age-standardised UK incidence increased by 10.3% between 1993 and 2002. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of first-line treatments for aggressive, or for relapsed aggressive, non-Hodgkin's lymphoma (diffuse large B-cell lymphoma)? We searched: Medline, Embase, The Cochrane Library, and other important databases up to January 2010 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 26 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: allogeneic stem-cell support, chemotherapy (conventional dose salvage, high-dose plus autologous transplant stem-cell support, conventional dose in people with chemosensitive disease), CHOP 14, CHOP 21, CHOP 21 with radiotherapy, CHOP 21 with rituximab, ACVBP, MACOP-B, m-BACOD, PACEBOM, and ProMACE-CytaBOM.

    Management of PCNSL occurring after successful treatment of systemic non-Hodgkin's lymphoma (NHL) is poorly defined. Illustrate a treatment approach for PCNSL following prior treatment of a systemic NHL. A retrospective case series of 6 patients (mean age 60 years; range 46-65) diagnosed with a diffuse large B cell lymphoma of the CNS following prior successful treatment of a systemic NHL (low-grade in 2; high-grade in 4). Mean interval to diagnosis of PCNSL after diagnosis of systemic NHL was 12 months (range 7-18). In 4/6 patients in whom genetic analysis could be performed, the PCNSL and NHL differed. Treatment utilized high-dose methotrexate and rituximab (immunochemotherapy) followed in patients with a radiographic complete response by autologous peripheral stem cell transplant (ASCT) with total body irradiation (TBI) and multi-agent conditioning chemotherapy (BEAM: carmustine, etoposide, cytarabine, melphalan). 5/6 patients had a radiographic complete response to immunochemotherapy and were treated with ASCT. 4/5 patients were free of disease following ASCT with a mean follow-up of 3 years (range 0.5-4 years). There were no toxic deaths and all patients transplanted successfully engrafted within 28 days (mean 18). Using a treatment paradigm similar to that utilized for recurrent systemic NHL (induction chemotherapy followed by ASCT) for PCNSL occurring metachronously after successful treatment of systemic NHL appears safe and effective.

    Non-Hodgkin's lymphoma (NHL) is rarely found in the jaw. We present 16 cases and the purpose of this study was to analyze the clinical signs and symptoms. The treatment and the progression evolution are also mentioned. The diagnosis was usually difficult and was often misleading and so delays before the first bone biopsy were frequent. The therapy of this rare, diffuse, large cell lymphoma was very variable from one case to another but the majority of the patients were treated with a combination of chemotherapy and radiotherapy.

    Burkitt lymphoma (BL) is the most frequent B-cell lymphoma in childhood. Genetically, it is characterized by the presence of an IG-MYC translocation which is supposed to be an initiating but not sufficient event in Burkitt lymphomagenesis. In a recent whole-genome sequencing study of four cases, we showed that the gene encoding the ras homolog family member A (RHOA) is recurrently mutated in pediatric BL. Here, we analyzed RHOA by Sanger sequencing in a cohort of 101 pediatric B-cell lymphoma patients treated according to Non-Hodgkin's Lymphoma Berlin-Frankfurt-Münster (NHL-BFM) study protocols. Among the 78 BLs in this series, an additional five had RHOA mutations resulting in a total incidence of 7/82 (8.5%) with c.14G>A (p.R5Q) being present in three cases. Modeling the mutational effect suggests that most of them inactivate the RHOA protein. Thus, deregulation of RHOA by mutation is a recurrent event in Burkitt lymphomagenesis in children.

    There are few studies examining complementary and alternative medicine (CAM) use and beliefs among non-Hodgkin lymphoma (NHL) survivors. 719 NHL patients from the University of Iowa/Mayo Clinic Molecular Epidemiology Resource who completed the 3-year post-diagnosis questionnaire were included in this study. 636 (89%) reported ever using CAM, with 78% utilizing vitamins, 54% alternative therapies and 45% herbals. Female gender was associated with increased overall CAM use (P<.0001) as well as use of vitamins (P<.0001), herbals (P=.006) and alternative therapy (P=.0002) for cancer. Older age (>60) was associated with increased vitamin use (P=.005) and decreased herbal use (P=.008). Among users, 143 (20%) believe CAM assists healing, 123 (17%) believe CAM relieves symptoms, 122 (17%) believe CAM gives a feeling of control, 110 (15%) believe CAM assists other treatments, 108 (15%) believe CAM boosts immunity, 26 (4%) believe CAM cures cancer, and 36 (5%) believe CAM prevents the spread of cancer.

    Fifty-two cases of non-Hodgkin's lymphoma (NHL) in the oral and maxillofacial region, comprising 31 submucosal (extra-nodal) and 21 cervical node NHLs, were investigated. The patients' ages ranged from 5 to 86 years, with a bimodal age distribution among young people below 12 years of age (average 8 years) and in those aged 30 years or older (average 60.3 years). The male-to-female gender difference ratio was 1.3:1. Patients presented with swelling as the major symptom. Histologically, diffuse, large cell malignant lymphoma was the most frequent type and 67.9% of lymphomas were of intermediate malignancy as defined by the Working Formulation for Clinical Usage. All submucosal lymphomas showed diffuse proliferation patterns, although follicular proliferation was identified in 5 of the 21 nodal lymphomas. Immunohistochemistry showed that the B-cell type was predominant, especially in nodal lymphomas. PMID:9234189

    Background There are several suspected environmental risk factors for non-Hodgkin lymphoma (NHL). The associations between NHL and environmental chemical exposures have typically been evaluated for individual chemicals (i.e., one-by-one). Objectives We determined the association between a mixture of 27 correlated chemicals measured in house dust and NHL risk. Methods We conducted a population-based case–control study of NHL in four National Cancer Institute–Surveillance, Epidemiology, and End Results centers—Detroit, Michigan; Iowa; Los Angeles County, California; and Seattle, Washington—from 1998 to 2000. We used weighted quantile sum (WQS) regression to model the association of a mixture of chemicals and risk of NHL. The WQS index was a sum of weighted quartiles for 5 polychlorinated biphenyls (PCBs), 7 polycyclic aromatic hydrocarbons (PAHs), and 15 pesticides. We estimated chemical mixture weights and effects for study sites combined and for each site individually, and also for histologic subtypes of NHL. Results The WQS index was statistically significantly associated with NHL overall [odds ratio (OR) = 1.30; 95% CI: 1.08, 1.56; p = 0.006; for one quartile increase] and in the study sites of Detroit (OR = 1.71; 95% CI: 1.02, 2.92; p = 0.045), Los Angeles (OR = 1.44; 95% CI: 1.00, 2.08; p = 0.049), and Iowa (OR = 1.76; 95% CI: 1.23, 2.53; p = 0.002). The index was marginally statistically significant in Seattle (OR = 1.39; 95% CI: 0.97, 1.99; p = 0.071). The most highly weighted chemicals for predicting risk overall were PCB congener 180 and propoxur. Highly weighted chemicals varied by study site; PCBs were more highly weighted in Detroit, and pesticides were more highly weighted in Iowa. Conclusions An index of chemical mixtures was significantly associated with NHL. Our results show the importance of evaluating chemical mixtures when studying cancer risk.

    A role for genetic susceptibility in non-Hodgkin lymphoma (NHL) is supported by the accumulating evidence of common genetic variations altering NHL risk. However, the pattern of NHL heritability remains poorly understood. We conducted a pooled analysis of 10 211 NHL cases and 11 905 controls from the International Lymphoma Epidemiology Consortium (InterLymph) to evaluate NHL risk among those with hematopoietic malignancies in first-degree relatives. Odds ratios (ORs) and 95% confidence intervals (CIs) of NHL and its subtypes were estimated from unconditional logistic regression models with adjustment for confounders. NHL risk was elevated for individuals who reported first-degree relatives with NHL (OR = 1.5; 95% CI = 1.2-1.9), Hodgkin lymphoma (OR = 1.6; 95% CI = 1.1-2.3), and leukemia (OR = 1.4; 95% CI = 1.2-2.7). Risk was highest among individuals who reported a brother with NHL (OR = 2.8; 95% CI = 1.6-4.8) and was consistent for all NHL subtypes evaluated. If a first-degree relative had Hodgkin lymphoma, NHL risk was highest if the relative was a parent (OR = 1.7; 95% CI = 1.0-2.9). If a first-degree relative had leukemia, NHL risk was highest among women who reported a sister with leukemia (OR = 3.0; 95% CI = 1.6-5.6). The pattern of NHL heritability appeared to be uniform across NHL subtypes, but risk patterns differed by specific hematopoietic malignancies and the sex of the relative, revealing critical clues to disease etiology.

    Non-Hodgkin lymphomas (NHL) disproportionately affect older patients who uncommonly receive allogeneic hematopoietic cell transplantation (HCT). We analyzed CIBMTR data on 1248 patients ≥40 years receiving reduced-intensity conditioning (RIC) or non-myeloablative (NMA) HCT for aggressive (n=668) and indolent (n=580) NHL. Aggressive lymphoma was more frequent in the oldest cohort [(age 40–54) 49% vs. (55–64) 57% vs. (≥65) 67% p=0.0008]; fewer patients ≥65 had prior autografting [26% vs. 24% vs. 9%; p=0.002)]. Rates of relapse, acute and chronic GVHD and non-relapse mortality (NRM) at one year were similar [22%, 95% confidence interval (CI) 19–26%; 27%, 95% CI 23–31%; 34%, 95% CI 24–44%]. Progression-free (PFS) and overall (OS) survival at 3 years was slightly lower in older cohorts [OS:54%, 95% CI 50–58%; 40%, 95% CI 36–44%; 39%, 95% CI 28–50%; p<0.0001]. Multivariate analysis revealed no significant effect of age on acute or chronic GVHD or relapse. Age ≥55 years, Karnofsky performance status <80, and HLA-mismatch adversely impacted NRM, PFS, and OS. Disease status at HCT, but not histologic subtype, worsened NRM, relapse, PFS and OS. Even for patients ≥55 years, OS still approached 40% at 3 years suggesting HCT effects long-term remissions and remains underutilized in qualified older patients with NHL. PMID:24641829

    Gene amplification characterized by distinct cytogenetic structures, such as homogeneously stained regions (hsrs), aberrantly banded marked chromosomes (abms), and double minutes (dmins) chromosomes is commonly found in tumor cells, and is considered as an important mechanism by which tumor cells gain increased levels of expression of critical genes. Very little is known about gene amplification in NHL. So far, no commonly amplified gene(s) have been identified in NHL. DNA in-gel renaturation assay provided evidence for the presence of amplified DNA fragments in NHL. In order to identify the gene(s) amplified in NHL we performed a modified form of CGH (hybridization and normal chromosomes with biotin labeled tumor DNA) to a panel of 10 NHL, which showed cytogenetic evidence for gene amplification in the form of hsrs and dmins. A number of chromosomal regions were found to be non-randomly amplified: 1p32-36(9/10), 1q32-44(6/10), 6p(9/10), 6q26-27(5/10), 16(8/10), 19(7/10) and 22q(7/10). Amplification of DNA from specific chromosomal bands was noted at 4p16(8/10), 11q13(10/10), and 12q24(8/10). Tumor L-10 showed specific amplification of 2p13. This study details the first CGH study performed on a panel of NHLs to identify gene amplification and chromosomal origin of hsrs and dmins identified by conventional cytogenetic analysis. The modified CGH employed in this study indicated that gene amplification is a frequent genetic alteration in NHL.

    The objective of this study was to assess the impact of the primary prophylaxis of granulocyte colony-stimulating factor (G-CSF) in the management of childhood B-cell non-Hodgkin lymphoma (B-NHL). Patients with advanced-stage mature B-NHL were randomized to receive prophylactic G-CSF (G-CSF+) or not receive G-CSF (G-CSF-) based on protocols of the B-NHL03 study. The G-CSF group received 5 μg/kg/d Lenograstim from day 2 after each course of six chemotherapy courses. Fifty-eight patients were assessable, 29 G-CSF + and 29 G-CSF-. G-CSF + patients showed a positive impact on the meantime to neutrophil recovery and hospital stay. On the other hand, they had no impact in the incidences of febrile neutropenia, serious infections, stomatitis and total cost. Our study showed that administration of prophylactic G-CSF through all six chemotherapy courses for childhood B-NHL showed no clinical and economic benefits for the management of childhood B-NHL treatment.

    The aim of this study was to investigate serum levels of IL-2, IL-6 and IL-10 in the pretreatment period and to determine if high IL-2, IL-6, IL-10 levels correlate with the outcome in patients with Non-Hodgkin's Lymphoma (NHL) in the post treatment period. Forty-three patients with the diagnosis of aggressive NHL were included in our study. In all cases initial treatment consisted of CHOP. Patients who failed initial therapy and relapsed from CR were treated with the ESHAP regimen or autologous bone marrow transplantation. The median follow-up duration was 127 weeks (20-228 weeks). There was a negative relationship between the failure-free survival and IL-2 levels (p<0.01). IL-2 levels were negatively correlated with overall survival (p<0.02). There was no relationship between the failure-free survival and IL-6 and IL-10 levels. IL-6 and IL-10 levels did not affect overall survival. In conclusion, in patients with lymphoma, the immune system tries to control the progression of tumor thus leading to high IL-2 levels. PMID:15595640

    Background: Acute lymphoblastic leukemia (ALL) and non-Hodgkin's lymphoma (NHL) are the most common malignancies in children and adolescents. Therapies such as corticosteroids, cytotoxic and radiotherapy will have harmful effect on bone mineral density (BMD) which can lead to increased possibility of osteoporosis and pathological fractures. Subjects and methods: This 3-year cross-sectional study was performed in 50 children with ALL (n=25) and NHL (n=25) at Dr. Sheikh Children's Hospital in Mashhad. Half the patients received chemotherapy alone (n=25), while the other half received chemotherapy plus radiotherapy (n=25). We assessed them in the remission phase by DEXA bone mineral densitometry at the lumbar spine and femoral neck (hip). The survey results were adjusted in accordance with age, height, sex and Body Mass Index. Results : The mean age was 3.93± 8.28 years. There was no significant difference in bone biomarkers (Ca, P, ALP, PTH) among ALL, NHL and also the two treatment groups. Children with ALL had lower density at the hip and lumbar spine (p-value<0.001 and p-value=0.018, respectively). Among the total of 50 patients, 3 patients had normal results for detected hip BMD (6%), while 14 (28%) had osteopenia and 33 had osteoporosis (66%). Only one patient had normal BMD among all the patients who received chemotherapy plus radiotherapy, whereas 2 patients had normal BMD with just chemotherapy treatment. Conclusion : Given that 94% of our patients had abnormal bone density, it seems to be crucial to pay more attention to the metabolic status and BMD in children with cancer. PMID:27489591

    Background Phenoxy herbicides have been used widely in agriculture, forestry, parks and domestic gardens. Early studies linked them with soft tissue sarcoma (STS) and non-Hodgkin lymphoma (NHL), but when last reviewed by the International Agency for Research on Cancer in 1986, the evidence for human carcinogenicity was limited. Sources of data We searched Medline and Embase, looking for cohort or case-control studies that provided data on risk of STS and/or NHL in relation to phenoxy herbicides, and checked the reference lists of relevant publications for papers that had been missed. Areas of agreement, areas of controversy The extensive evidence is not entirely consistent, and a hazard of STS or NHL cannot firmly be ruled out. However, if there is a hazard, then absolute risks must be small. Growing points, areas timely for developing research Extended follow-up of previously assembled cohorts may be the most efficient way of further reducing uncertainties. PMID:25790819

    Three diffuse centroblastic lymphomas developed at the site of previous surgery. Two were preceded by atypical lymphoid infiltrates. Clinical data, microscopic features, and immunophenotypic studies were reviewed. All three patients presented with soft tissue masses at the site of previous surgery and metallic implants, with no evidence of lymphadenopathy, hepatosplenomegaly, or bone marrow involvement. There was no history of immunosuppression or risk factors. In two cases the initial diagnosis was of atypical lymphoid infiltrate progressing to lymphoma. Pathological examination showed a diffuse centroblastic lymphoma with an angiocentric pattern in one case. Phenotypic studies confirmed B cell origin. Soft tissue malignant lymphoma, though uncommon, can occur at the site of previous orthopaedic surgery, in particular joint replacement. Atypical lymphoid infiltrate may signal such an event.

    The Japan Association of Childhood Leukemia Study (JACLS) NHL-98 is a multicenter study designed to evaluate treatment outcomes in Japanese children with B-cell non-Hodgkin lymphoma (B-NHL) and mature B-cell acute lymphoblastic leukemia (B-ALL). The study was supported by a central pathology review system and used a new, standardized protocol with short, intensive treatment regimens. From April 1998 to May 2002, 69 patients with B-NHL and B-ALL up to 16 years of age were enrolled in the NHL-98 study. Treatment was stratified by risk group; patients with limited disease were in groups A and B, and those with extensive disease were in groups C and D. Patients in groups B, C, and D received consolidation phases with high-dose methotrexate (HDMTX) followed by other multi-agent chemotherapy. Patients in group A did not receive either MTX or etoposide. Only patients in group D received etoposide. The event-free survival rates were 100% in groups A and B, 75.1% in group C, and 66.2% in group D. Overall, patients with limited disease had favorable results. For patients with extensive disease, additional treatment options such as increased doses of anticancer drugs warrant further investigation. PMID:21261497

    We report here on treatment results of consecutive CCLSG NHL studies (NHL855, 1985-1989; NHL890, 1989-1996). The NHL855 protocol consisted of an induction phase of five drugs (VCR, PRD, CPM, DXR, and high-dose MTX) and a maintenance phase of 7 drugs. The probabilities of EFS at 7 years were 78% (SE, 10%) for the patients with localized disease, and 38% (SE, 7%) for those with advanced disease. In the NHL 890 protocol, the patients were assigned to two different treatment groups according to their histology and received different consolidation therapy; non-lymphoblastic subtype was treated almost identically to NHL855 while LASP and VP-16 were newly added for the lymphoblastic subtype. The 7-year EFS improved to 91% (SE, 6%) for localized disease, and 61% (SE, 6%) for advanced disease. A remarkable improvement was particularly evident for lymphoblastic type with mediastinal mass. Optional trial of high-dose sequential chemotherapy and peripheral blood progenitor cell auto grafting resulted in an unfavorable outcome. The 7-year EFS according to main histological subgroups were as follows: 84% (10%) for large cell type, 67% (11%) for Burkitt's-type, 58% (10%) for lymphoblastic type. Secondary cancer occurred in two of the 163 patients studied. Both patients were AML (M0/M4) and MLL rearrangement was detected in the M4 case. PMID:9597895

    Objectives To provide further information on the possible carcinogenicity of phenoxy herbicides, and in particular their relationship to soft tissue sarcoma (STS), non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukaemia (CLL). Methods We extended follow-up to December 2012 for 8,036 men employed at five factories in the UK which had manufactured phenoxy herbicides, or in a contract spraying business. Mortality was compared with that for England and Wales by the person-years method. Nested case-control analyses compared men with incident or fatal STS (n=15) or NHL/CLL (n=74) and matched controls (up to 10 per case). Results 4,093 men had died, including 2,303 since the last follow-up. Mortality from all causes and all cancers was close to expectation, but an excess of deaths from NHL was observed among men who had worked for ≥ 1 year in jobs with more than background exposure to phenoxy herbicides (19 deaths, standardised mortality ratio 1.85, 95% confidence interval (CI) 1.12-2.89). Four deaths from STS occurred among men potentially exposed above background (3.3 expected). In the nested case-control analyses, there were no significantly elevated risks or consistent trends across categories of potential exposure, for either STS or NHL/CLL. The highest odds ratio (for STS in men who had worked for ≥1 year in potentially exposed jobs) was only 1.30 (95%CI 0.30-5.62). Conclusions Our findings are consistent with the current balance of epidemiological evidence. If phenoxy herbicides pose a hazard of either STS or NHL then any absolute increase in risk is likely to be small. PMID:25694496

    Mature (peripheral) T-cell lymphoma (PTCL) other than anaplastic large cell lymphoma is a heterogeneous group of diseases and exceedingly rare in children and adolescents. Survival rates range between 46% and 85%. This study reports the disease characteristics, treatment and outcome of all patients with the diagnosis of mature TCL registered in the Berlin-Frankfurt-Munster non-Hodgkin lymphoma database between 1986 and 2012. All diagnoses were centrally reviewed and revised by clinico-pathological correlation according to the criteria of the current World Health Organization classification. Of the 69 patients originally registered as having PTCL, the diagnosis was confirmed in 38 of them. Most patients were treated with an anaplastic large cell lymphoma (ALCL)-like therapy regimen. Patients with PTCL-not otherwise specified comprised the largest group and showed a 5-year event-free survival rate of 61 ± 11%. Patients suffering from Natural Killer/T-cell- and hepatosplenic TCL had the poorest outcome. Our results suggest that the outcomes of children with mature TCL other than ALCL depend on the subtype and are worse than in all other paediatric lymphomas. The clinical experience presented in this largest study on paediatric mature TCL may serve as basis for future collaborative international prospective clinical trials. PMID:25395120

    Lymphoma is the third most common pediatric neoplasm. Non-Hodgkin lymphoma (NHL) accounts for nearly half of cases and commonly involves extranodal sites. Compared with adults, this histologic spectrum of pediatric NHL is very narrow and consists of aggressive tumors. Patients typically present with widespread disease. Generally, NHL occurring in children includes Burkitt lymphoma, lymphoblastic lymphoma, diffuse large B-cell lymphoma, and anaplastic large cell lymphoma. Staging and assessment of therapeutic response are usually based on FDG-PET/CT. Due to the increased susceptibility of young patients to the effects of ionizing radiation, alternative methods of imaging are being explored. PMID:27265605

    From June 1990 to February 1996, 35 patients with B-cell acute lymphoblastic leukaemia (B-ALL) 13 of whom had CNS disease and 28 patients with stage IV B-cell non-Hodgkin's lymphoma (B-NHL) 22 of whom had CNS involvement were treated with a short, intensive multiagent chemotherapy regimen (UKCCSG 9003 protocol) based on the French LMB 86 regimen. Fifty-five were boys. The age range was 11 months to 16.5 years (median 8.4 years). Chemotherapy included cyclophosphamide, vincristine, daunorubicin, high-dose methotrexate (COPADM) and etoposide/high-dose cytarabine (CYVE) with frequent intrathecal (i.t.) triple therapy (methotrexate, cytarabine and hydrocortisone). Cranial irradiation (24 Gy in 15 fractions) was recommended in patients with overt CNS disease. One patient with Wiskott-Aldrich syndrome was withdrawn after entry and has been excluded from the analysis. Ten patients (16%) have relapsed (CNS, four; BM, two; combined CNS and BM, three; and jaw, one) 4-11 months after diagnosis and two patients never achieved complete remission (CR). All have died. In seven of the patients who relapsed, treatment had been modified or delayed because of poor clinical condition. Seven patients (11%) died of toxicity 11 days to 4 months after diagnosis. The cause of death was sepsis (n = 5) or sepsis with renal failure (n = 2). With a median follow-up of 3.1 years from diagnosis (range 9 months to 6.3 years), 43 patients (69%) survive in CR. This study confirms the effectiveness of this regimen with regard to the relapse rate (16%), although the rate of toxic death is of concern. PMID:9649146

    A population-based case-control study evaluated the relationship between soft tissue sarcoma and non-Hodgkin's lymphoma and past exposure to phenoxy herbicides and chlorophenols in western Washington state. A major purpose of the study was to determine if the risk of cancer was elevated in relation to chemicals potentially contaminated with 2,3,7,8-tetra-chlorodibenzo-p-dioxin (TCDD). A total of 160 men with soft tissue sarcoma and 581 men with non-Hodgkin's lymphoma were group-matched with 694 randomly selected controls and were interviewed in person. Among the general population, no increased risks for either cancer were seen in relation to intensity or duration of past exposure to phenoxy herbicides or chlorophenols. Preliminary risk estimates for specific occupations that involve phenoxy herbicide or chlorophenol exposure included: farmer, herbicide formulator, applicator, forest sprayer, farmland sprayer, work in sprayed area, and work with or manufacture chlorophenyls. In addition, the risks of both soft tissue sarcoma and non-Hodgkin's lymphoma were elevated among men with past exposure to various insecticides, organic solvents and metals, and among those with preexisting compromise of the immune system. Multivariate studies are in progress to ascertain the contribution of diverse factors to the risks of soft tissue sarcoma or non-Hodgkin's lymphoma in association with phenoxy herbicides, chlorophenols, and/or TCDD.

    With the recent success of the Bruton's tyrosine kinase (BTK) inhibitor, ibrutinib, and the phosphoinositide-3-kinase (PI3K) inhibitor, idelalisib, in the treatment of patients with relapsed or refractory non-Hodgkin's lymphoma (NHL), a number of new agents targeting the B-cell receptor (BCR) pathway are in clinical development. In addition, multiple trials combining these agents with conventional cytotoxic chemotherapy, immunomodulatory agents, monoclonal antibodies, or other kinase inhibitors are underway. This review will summarize the current data with the use of single agent and combination therapy with BCR inhibitors in NHL. In addition, commonly encountered as well as serious toxicities and hypothesized resistance mechanisms will be discussed. Lastly, this review will examine the future of these agents and opportunities to maneuver them into the front-line setting in selected NHL subtypes. PMID:26637705

    Introduction Anaplastic large cell lymphoma (ALCL) is a type of non-Hodgkin lymphoma that has strong expression of CD30. ALCL can sometimes involve the bone marrow, and in advanced stages, it can produce destructive extranodal lesions. But anaplastic large cell lymphoma kinase (ALK)+ ALCL with soft tissue involvement is very rare. Case report A 35-year-old woman presented with waist pain for over 1 month. The biopsy of soft tissue lesions showed that these cells were positive for ALK-1, CD30, TIA-1, GranzymeB, CD4, CD8, and Ki67 (90%+) and negative for CD3, CD5, CD20, CD10, cytokeratin (CK), TdT, HMB-45, epithelial membrane antigen (EMA), and pan-CK, which identified ALCL. After six cycles of Hyper-CVAD/MA regimen, she achieved partial remission. Three months later, she died due to disease progression. Conclusion This case illustrates the unusual presentation of ALCL in soft tissue with a bad response to chemotherapy. Because of the tendency for rapid progression, ALCL in young adults with extra-nodal lesions are often treated with high-grade chemotherapy, such as Hyper-CVAD/MA. PMID:27445489

    The Authors present three cases of Non-Hodgkin's Lymphoma (NHL) in pregnancy and discuss about problem of diagnosis and management of NHL in this condition. They stress that the diagnosis of NHL in pregnancy is delayed and the clinical progression of lymphoma is probably influenced by hormonal and immunological changes occurring during pregnancy. On the other hand the management of NHL is problematic because radiotherapy is potentially teratogenic. (By editorial staff). PMID:2776787

    Background Classical Hodgkin lymphoma (cHL) survivors are at increased risk to develop secondary non-Hodgkin lymphomas (sNHL). The outcome of patients with sNHL relative to their de novo counterparts (dnNHL) is unknown. Methods We utilized data of 26,826 HL cases from the Surveillance Epidemiology and End Results (SEER) program diagnosed between 1992 and 2009 to obtain the risk of further development of different subtypes of sNHL. We then compared survival of sNHL with the survival of matched dnNHL patients. Results The estimated cumulative incidence of sNHL was 2.50% (95% C.I. 2.10-2.89) after 15 years from the diagnosis of cHL. The standardized incidence ratio (SIR) was 10.5 (95% C.I. 8.9-12.4) for aggressive B-cell NHL, 4.0 (95% C.I. 3.1-5.1) for indolent B-cell NHL and 14.6 (95% C.I. 10.3-20.1) for T cell NHL. Patients with indolent B-cell sNHL had worse OS than their dnNHL counterparts (HR of death 2.7, 95% CI 1.3-5.7). Survival was not significantly different between sNHL and dnNHL for aggressive B-cell NHL (HR 1.3, 95% C.I. 0.6-2.7) or T-cell NHL (HR 0.8, 95% C.I 0.3-1.8). Conclusions The risk of developing sNHL after cHL is substantial. While patients with indolent B-cell sNHL have inferior survival, patients with aggressive B-cell sNHL and T-cell sNHL have survival comparable to their de novo counterparts. PMID:23797978

    Introduction: Primary musculoskeletal extranodal non-Hodgkin lymphoma is a rare presentation and account for 5% of all primary extranodal non-Hodgkin lymphomas. Treatment uses a combination of chemotherapy and radiotherapy with good prognosis in unifocal manifestation. We report an unusual case of primary musculoskeletal extranodal lymphoma presenting as a soft tissue swelling around the wrist. Case Report: A 75 year old lady was referred to the Orthopaedic Outpatients Department with a painless, slowly growing mass on the dorsum of the right wrist. Clinical examination revealed a 6 X 9 cm round painless mass on the dorsum of the distal radius adherent to both the underlying structures and skin. MRI of the wrist showed a large mass causing extensive osteolysis of the distal radius and extending proximally with abnormal replacement of the marrow. The patient was brought to theatre for biopsy and subsequent histopathological examination confirmed a B-cell non-Hodgkin lymphoma. The patient was referred to the Haematology Service for further treatment and follow-up. She received chemotherapy and radiotherapy with satisfactory results. Conclusion: Lymphoma presenting as a soft tissue mass is relatively uncommon and can easily be confused with a wide variety of inflammatory conditions, more common neoplasias as well as infectious diseases (tuberculosis). Though rare, extranodal lymphoma should be regularly included in the differential diagnosis of mass lesions. PMID:27299029

    The head and neck region is the second most common site for the development of extranodal lymphomas. Richter's syndrome (RS) involves the transformation of B-cell chronic lymphocytic leukemia (B-CLL) to an aggressive lymphoma, most commonly, diffuse large B-cell lymphoma (DLBCL). We report the case of a 62-year-old man who developed DLBCL in the periorbital region 2 months after blunt trauma to the site. The patient lacked other physical symptoms at the time of presentation. Bone marrow biopsy and immunophenotypic analysis revealed a Richter transformation of unknown B-CLL. RS frequently arises in lymph nodes or bone marrow and rarely presents with extranodal involvement. Chemotherapy resulted in total remission of the lymphoma and no relapse was observed in the 6-month follow-up period. This case demonstrates that the clinician must recognize that unresolved soft tissue swelling after a trauma may be caused by NHL. PMID:20451833

    Although malignant lymphoma is split in over 60 distinct entities, four of them, diffuse large B cell lymphoma, follicular-, Hodgkin's- and mantle cell lymphoma constitute more than half of all new cases. A recent major revision of the Ann Arbor staging system restricts the suffix “A” and “B” just to Hodgkin's lymphoma. Bone marrow exams are abandonned in Hodgkin's and restricted in DLBCL. PET exams at different time points are crucial. PET guided therapy will lead to a reduction of the use of chemo- and radiation therapy. Many new targeted drugs have been introduced. Their therapeutic index is impressive as is their price tag. The radiation and chemotherapy free treatment of malignant lymphoma is within reach. PMID:26732717

    Non Hodgkin's lymphomas (NHL) constitute a heterogeneous group of neoplasm of the lymphoid system. There are many histological subtype of NHL based on WHO classification of hematopoietic and lymphoid neoplasm. This cross-sectional study was carried out in the department of Pathology, Dhaka Medical College, Dhaka from January 2009 to December 2010 to observe the different subtypes of NHL using immunohistochemistry (IHC) with CD3. A total of 50 microscopically diagnosed case of NHL irrespective of age and sex were included in the study. The diagnostic morphologic criteria of each lymphoma subcategory were compiled and diagnosis was made. Mean age of the study subjects were 42.0±19.7 years with range 3-75 years and male female ratio was 1.8:1. Nodal NHL was 66% and extranodal cases were 34%. Maximum number of histolgic subtypes belonged to diffuse large B-cell lymphoma (DLBCL) and male was predominant in all histological subtypes, except peripheral T-cell lymphoma (PTCL). DLBCL was predominant in all B-cell NHL whereas PTCL was predominant in all T-cell NHL. The most childhood patients belonged to lymphoblastic lymphoma. Regarding cell lineage B-cell NHL was more common than T-cell NHL (88% vs. 12%), but high grade pattern was more predominant in T-cell type (83.3% vs. 65.9%). Among 50 study subjects histological (H & E) diagnosis reveals 46 cases as B-cell NHL and 4 as T-cell NHL but IHC confirms 6 cases as T-cell NHL. PMID:25725676

    Background Non-Hodgkin lymphoma (NHL), the most common hematologic malignancy, consists of numerous subtypes. The etiology of NHL is incompletely understood, and increasing evidence suggests that risk factors may vary by NHL subtype. However, small numbers of cases have made investigation of subtype-specific risks challenging. The International Lymphoma Epidemiology Consortium therefore undertook the NHL Subtypes Project, an international collaborative effort to investigate the etiologies of NHL subtypes. This article describes in detail the project rationale and design. Methods We pooled individual-level data from 20 case-control studies (17471 NHL cases, 23096 controls) from North America, Europe, and Australia. Centralized data harmonization and analysis ensured standardized definitions and approaches, with rigorous quality control. Results The pooled study population included 11 specified NHL subtypes with more than 100 cases: diffuse large B-cell lymphoma (N = 4667), follicular lymphoma (N = 3530), chronic lymphocytic leukemia/small lymphocytic lymphoma (N = 2440), marginal zone lymphoma (N = 1052), peripheral T-cell lymphoma (N = 584), mantle cell lymphoma (N = 557), lymphoplasmacytic lymphoma/Waldenström macroglobulinemia (N = 374), mycosis fungoides/Sézary syndrome (N = 324), Burkitt/Burkitt-like lymphoma/leukemia (N = 295), hairy cell leukemia (N = 154), and acute lymphoblastic leukemia/lymphoma (N = 152). Associations with medical history, family history, lifestyle factors, and occupation for each of these 11 subtypes are presented in separate articles in this issue, with a final article quantitatively comparing risk factor patterns among subtypes. Conclusions The International Lymphoma Epidemiology Consortium NHL Subtypes Project provides the largest and most comprehensive investigation of potential risk factors for a broad range of common and rare NHL subtypes to date. The analyses contribute to our understanding of the multifactorial nature of NHL

    Non-Hodgkin lymphomas (NHLs) are often present outside the lymph nodes. Although primary extranodal NHLs (PE-NHL) form a substantial part of all NHLs, reports on oral PE-NHLs are rare. Forty patients with PE-NHL of the oral cavity have been studied for the distribution of gender, age, oral subsite and presenting complaint, histological subtype according to the WHO classification, clinical stage, treatment, and follow-up. The data are reviewed against the background of the literature. Furthermore, the International Prognostic Index has been taken into consideration. All patients had a lymphoma of B-cell lineage. Two-thirds of patients presented with locoregional disease. Mean survival time was 38 months, with a mean recurrence-free survival time of 31 months. There was no statistically significant difference in survival time between patients with bone versus soft tissue localisation of the PE-NHL. In view of the rarity of PE-NHL involving the oral region multicenter studies are needed for evaluation of the usefulness of the International Prognostic Index for non-Hodgkin lymphoma in this particular part of the body.

    2014-01-01

    Background NHL (non-Hodgkin lymphoma) consists of over 60 subtypes, ranging from slow-growing to very aggressive. The three largest subtypes are DLBCL (diffuse large B-cell lymphoma), FL (follicular lymphoma), and CLL/SLL (chronic lymphocytic leukemia/small lymphocytic lymphoma). For each subtype, different racial groups have different presentations, etiologies, and prognosis patterns. Methods SEER (Surveillance, Epidemiology, and End Results) data on DLBCL, FL, and CLL/SLL patients diagnosed between 1992 and 2010 were analyzed. Racial groups studied included NHW (non-Hispanic whites), HW (Hispanic whites), blacks, and API (Asians and Pacific Islanders). Patient characteristics, age-adjusted incidence rate, and survival were compared across races. Stratification and multivariate analysis were conducted. Results There are significant racial differences for patients’ characteristics, including gender, age at diagnosis, stage, lymph site, and age, and the patterns vary across subtypes. NHWs have the highest incidence rates for all three subtypes, followed by HWs (DLBCL and FL) and blacks (CLL/SLL). The dependence of the incidence rate on age and gender varies across subtypes. For all three subtypes, NHWs have the highest five-year relative survival rates, followed by HWs. When stratified by stage, racial difference is significant in multiple multivariate Cox regression analyses. Conclusions Racial differences exist among DLBCL, FL, and CLL/SLL patients in the U.S. in terms of characteristics, incidence, and survival. The patterns vary across subtypes. More data collection and analysis are needed to more comprehensively describe and interpret the across-race and subtype differences. PMID:25560974

    BACKGROUND Genetic susceptibility studies of lymphoma may serve to identify at risk populations and to elucidate important disease mechanisms. METHODS This review considered all studies published through October 2006 on the contribution of genetic polymorphisms in the risk of lymphoma. RESULTS Numerous studies implicate the role of genetic variants that promote B-cell survival and growth with increased risk of lymphoma. Several reports including a large pooled study by InterLymph, an international consortium of non-Hodgkin lymphoma (NHL) case-control studies, found positive associations between variant alleles in TNF -308G>A and IL10 -3575T>A genes and risk of diffuse large B-cell lymphoma. Four studies reported positive associations between a GSTT1 deletion and risk of Hodgkin and non-Hodgkin lymphoma. Genetic studies of folate-metabolizing genes implicate folate in NHL risk, but further studies that include folate and alcohol assessments are needed. Links between NHL and genes involved in energy regulation and hormone production and metabolism may provide insights into novel mechanisms implicating neuro- and endocrine-immune cross-talk with lymphomagenesis, but will need replication in larger populations. CONCLUSIONS Numerous studies suggest that common genetic variants with low penetrance influence lymphoma risk, though replication studies will be needed to eliminate false positive associations.

No definite difference was observed both in actuarial and relapse-free five-year survival rate between stage I and II. There was a high survival rate with orbital NHL in which most of the patients occupied with favorable histology. Prognosis of the disease was highly influenced by the histologic subtype; five-year survival was 91.4% in DWDL, 77.2% in the DM, 52.0% in DPDL and 51.7% in DH. Application of histologic classification with the Working Formulation was also recommended. There was a high incidence of extranodal relapses to bone and/or soft tissue from the lesions with nasal cavity, paranasal sinus and oral cavity. PMID:3385929

    Non-Hodgkin lymphoma (NHL) comprises numerous biologically and clinically heterogeneous subtypes, with limited data examining risk factors for these distinct disease entities. Many limitations exist when studying lymphoma epidemiology, therefore until recently little was known regarding the etiology of NHL subtypes. This review highlights the results of recent pooled analyses examining risk factors for NHL subtypes. We outline heterogeneity and commonality among risk factors for NHL subtypes, with proposed subtype-specific as well as shared etiologic mechanisms. In addition, we describe how the study of lymphoma epidemiology may translate into prevention or therapeutic targeting as we continue to explore the complexities of lifestyle and genetic factors that impact lymphomagenesis.

    Comparative data on the distribution of non-Hodgkin lymphoma (NHL) subtypes in Southern Africa (SAF) is scarce. In this study, five expert haematopathologists classified 487 consecutive cases of NHL from SAF using the World Health Organization classification, and compared the results to North America (NA) and Western Europe (WEU). Southern Africa had a significantly lower proportion of low-grade (LG) B-NHL (34·3%) and a higher proportion of high-grade (HG) B-NHL (51·5%) compared to WEU (54·5% and 36·4%) and NA (56·1% and 34·3%). High-grade Burkitt-like lymphoma was significantly more common in SAF (8·2%) than in WEU (2·4%) and NA (2·5%), most likely due to human immunodeficiency virus infection. When SAF patients were divided by race, whites had a significantly higher frequency of LG B-NHL (60·4%) and a lower frequency of HG B-NHL (32·7%) compared to blacks (22·5% and 62·6%), whereas the other races were intermediate. Whites and other races had a significantly higher frequency of follicular lymphoma and a lower frequency of Burkitt-like lymphoma compared to blacks. The median ages of whites with LG B-NHL, HG B-NHL and T-NHL (64, 56 and 67 years) were significantly higher than those of blacks (55, 41 and 34 years). Epidemiological studies are needed to better understand these differences. PMID:26898194

    Primary lymphoma of bone and soft tissue is rare and almost invariably of B-cell origin. Osseous lymphoma usually reveals aggressive bone destruction and associated soft tissue extension. Soft tissue involvement is optimally depicted by MR imaging. Cortical destruction allowing communication between the intraosseous and soft tissue components may be subtle with small striations of extension. Lymphoma of the deep soft tissues usually reveals long cones of intramuscular or intermuscular tumor again best depicted by MR imaging. Cutaneous or subcutaneous lymphoma demonstrates multiple nodules and plaquelike thickening. PMID:27265608

    Diffuse large B-cell lymphoma is extranodal in approximately 40% of cases, arising in nearly any organ system. DLBCL involvement of soft tissue and in particular skeletal muscle is extremely rare, comprising less than 1% of all extranodal non-Hodgkin lymphomas (NHL). We report a case of a 79-year-old man that presented with a DLBCL of the left triceps. In particular, we describe an unusual histologic appearance of pseudoglandular structures, resembling adenocarcinoma. We performed a review of lymphoma cases involving skeletal muscle diagnosed at our institution over the past 15 years as well as thorough PubMed review of the literature. We discuss the features of lymphoma involving skeletal muscle as it pertains to clinical characteristics, histologic subtype, tumor localization, diagnostic studies, therapy, and outcome. Finally, we highlight the diagnostic difficulties that can present in these rare and often challenging cases. PMID:27247818

    The relative frequency of the non-Hodgkin lymphoma (NHL) subtypes varies around the world. The objective of this study was to describe the general features of patients with lymphoma in Colombia. A total of 819 patients with a new diagnosis of lymphoma were included. Nighty-nine (12 %) of them had Hodgkin lymphoma (HL) and 720 (88 %) had NHL. Most cases had advanced stage disease at presentation (63.6 %). Diffuse large B cell lymphoma (DLBCL) was the most frequent diagnosis; it was seen in 40 % of patients with NHL and in 35 % of patients in the whole series. Overall survival rates at 3 years were 77 % for HL and follicular lymphoma, 54 % for DLBCL, and 45 % for T cell lymphomas. In conclusion, the distribution of specific NHL subtypes is similar to what has been reported previously in other tropical countries. PMID:25645655

    Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma, with about 30% of new cases presenting with extranodal disease. Lesions originating from soft tissues of the upper extremities are extremely rare and may mimic other malignancies like sarcoma. We present a case of an elderly patient with right upper extremity (RUE) mass which was proven to be DLBCL instead of sarcoma. We emphasize the increasing need for investigating new therapeutic options for patients of extreme age and/or with underlying heart disease. PMID:27486587

    With a lifetime risk of 1% and 700 new cases per year, Non-Hodgkin lymphoma (NHL) is the seventh most frequent type of cancer in Denmark. The incidence of NHL has increased considerably in Western countries over the last decades; consequently, NHL is an increasing clinical problem. Ophthalmic lymphoma, (lymphoma localized in the ocular region, i.e. eyelid, conjunctiva, lacrimal sac, lacrimal gland, orbit, or intraocularly) is relatively uncommon, accounting for 5%-10% of all extranodal lymphomas. It is, however, the most common orbital malignancy. The purpose of this thesis was to review specimens from all Danish patients with a diagnosis of ophthalmic lymphoma during the period 1980-2005, in order to determine the distribution of lymphoma subtypes, and the incidence- and time trends in incidence for ophthalmic lymphoma. Furthermore, an extended analysis of the most frequent subtype, extranodal marginal zone lymphoma (MALT lymphoma), was done to analyse clinical factors and cytogenetic changes with influence on prognosis. A total of 228 Danish patients with a biopsy-reviewed verified diagnosis of ocular adnexal-, orbital-, or intraocular lymphoma were identified. We found that more than 50% of orbital- and ocular adnexal lymphomas were of the MALT lymphoma subtype, whereas diffuse large B-cell lymphoma (DLBCL) predominated intraocularly (Sjo et al. 2008a). Furthermore, lymphoma arising in the lacrimal sac was surprisingly predominantly DLBCL (Sjo et al. 2006). Incidence rates were highly dependent on patient age. There was an increase in incidence rates for the whole population from 1980 to 2005, corresponding to an annual average increase of 3.4% (Sjo et al. 2008a). MALT lymphoma arising in the ocular region was found in 116 patients (Sjo et al. 2008b). One third of patients had a relapse or progression of disease after initial therapy and relapses were frequently found at extra-ocular sites. Overall survival, however, was not significantly poorer for patients

    Some autoimmune disorders are increasingly recognized as risk factors for non-Hodgkin lymphoma (NHL) overall, but large-scale systematic assessments of risk of NHL subtypes are lacking. We performed a pooled analysis of self-reported autoimmune conditions and risk of NHL and subtypes, including 29 423 participants in 12 case-control studies. We computed pooled odds ratios (OR) and 95% confidence intervals (CI) in a joint fixed-effects model. Sjögren syndrome was associated with a 6.5-fold increased risk of NHL, a 1000-fold increased risk of parotid gland marginal zone lymphoma (OR = 996; 95% CI, 216-4596), and with diffuse large B-cell and follicular lymphomas. Systemic lupus erythematosus was associated with a 2.7-fold increased risk of NHL and with diffuse large B-cell and marginal zone lymphomas. Hemolytic anemia was associated with diffuse large B-cell NHL. T-cell NHL risk was increased for patients with celiac disease and psoriasis. Results for rheumatoid arthritis were heterogeneous between studies. Inflammatory bowel disorders, type 1 diabetes, sarcoidosis, pernicious anemia, and multiple sclerosis were not associated with risk of NHL or subtypes. Thus, specific autoimmune disorders are associated with NHL risk beyond the development of rare NHL subtypes in affected organs. The pattern of associations with NHL subtypes may harbor clues to lymphomagenesis. PMID:18263783

    Lymphomas of the ocular adnexa and intraocular tissue include a wide range of lymphoproliferative neoplastic disorders. They are predominantly extranodal non-Hodgkin lymphomas (NHL). The World Health Organization (WHO) classification of lymphoid neoplasm and individual morphological, immunophenotypical, and molecular genetic features, indicate that they may be divided into B-cell (approximately 80 % of all NHL) and T-cell lymphomas (approximately 10-20 % of all NHL). The most common forms of ocular NHL are extranodal marginal zone lymphoma (EMZL) of the mucosa-associated lymphoid tissue (MALT-type), follicular lymphoma (FL), diffuse large B-cell lymphoma, and mantel cell lymphoma. The clinical signs and symptoms are usually very unspecific and depend on the location, size, and extent of the underlying lymphoma subtype. Typical low grade lymphomas have an indolent clinical course and often remain unrecognized for many years. On the other hand, high grade NHLs, such as DLBCL or MCL, are frequently aggressive, with rapid tumour growth and poor prognosis, despite early detection. Histopathology is still the gold standard in the diagnosis of ocular lymphomas. Basic understanding of the principal pathophysiological and clinical aspects of the development and progression of orbital and ocular lymphomas seems to be mandatory for optimal diagnosis and treatment and for improving survival and prognosis. Both residents in training and board certified ophthalmologists should be aware of these problems. PMID:27468099

    Summary Indolent lymphoma comprises a unique and challenging subset of non-Hodgkin lymphoma (NHL). While definitions of indolence will vary, the most common indolent NHL subtypes include follicular lymphoma, marginal zone lymphoma, and small lymphocytic lymphoma. Patients with indolent NHL (iNHL) excluding those with rare localized presentations are often met with an incurable but highly treatable NHL. In the rituximab era, response rates are approaching 90% with rituximab plus chemotherapy and time to next treatment are beginning to be measured in years. As a result of a prolonged natural history, we are encountering a gridlock of novel regimens and agents that appropriately fill peer-reviewed journals. In this review, we tackle a spectrum of topics in the management of indolent lymphoma including the initial approach to the newly diagnosed patient, approaches to first cytotoxic chemotherapy, maintenance and consolidation techniques, as well as highlight promising treatments on the horizon in iNHL. Clinicians continue to face tough choices in the management of iNHL. Through well-thought out clinical trials and peer-reviewed vetting of data we will continue to determine how to best manage the clinical continuum that is iNHL. PMID:23063143

    Background and Aim Retrospective evaluation of hepatitis C virus (HCV) prevalence in lymphoma tissues has important applications in clarifying the contribution of viral factors to the pathogenesis. Trials for detection of HCV at the cellular level in lymphoma tissues are, so far, minimal with unsatisfactory results. We aimed to study the detection and localization of HCV in the tissues of B-cell non-Hodgkin lymphoma (NHL) patients. Design We performed immunohistochemistry to detect the HCV nonstructural 3 protein in paraffin-embedded tissue specimens of B-cell NHL patients, in 39 serum HCV-RNA positive samples and 35 serum HCV-RNA negative samples as controls. The serum analysis was carried out for HCV antibodies using enzyme-linked immunoassay and for HCV-RNA using reverse transcription-polymerase chain reaction. Reverse transcription-polymerase chain reaction was used to detect the HCV-RNA in tissues in immunohistochemically positive cases. We correlated the results with the clinicopathologic characteristics of the patients. Results A diffuse cytoplasmic immunohistochemical staining for HCV in the lymphoid cells was detected in 8 of 39 serum positive cases (20.5%), all of which were genotype 4, which is the most prevalent HCV genotype in Egypt. Only 2 out of 35 serum negative control samples showed positive staining and in 1 of them HCV-RNA was detected in tissue. No significant correlation was detected between HCV positive cases and the clinicopathologic features of the patients. Conclusions Immunohistochemical detection of HCV proteins in lymphoma tissues supports a potential role of viral replication in lymphomagenesis. The low number of cases showing expression of viral proteins may represent a low viral load in lymphoid tissue and/or restriction of HCV protein expression to certain subtypes of B-cell NHL. Immunohistochemistry can be used as a complementary tool for specific HCV detection in the paraffin-embedded material of lymphoma tissues not suitable for

    The records of 95 consecutive children less than or equal to 21 years of age with previously untreated diffuse histology NHL registered in our protocols from 1978 to 1983 were reviewed. Seventy-nine patients were considered eligible for analysis. The histologic subtypes represented included lymphoblastic (LB) 37%; histiocytic (DHL) 29%; undifferentiated (DU) 19%; poorly differentiated (DPDL) 9%; and unclassified (UNHL) 6%. Distribution of the patients according to stage showed Stage I, 0%; Stage II, 11%; Stage III, 53%; Stage IV, 36%. Four different Memorial Hospital protocols for systemic chemotherapy were used (LSA2L2 73%; L10 9%; L17 10%; L17M 8%); however, the IT (intrathecal) chemotherapy was uniform (Methotrexate: 6.0-6.25 mg/M2 per treatment course) and was included in the induction, consolidation, and maintenance phases of all treatment protocols. Cranial radiation was included in the induction, consolidation, and maintenance phases of all treatment protocols. Cranial radiation was not included in the CNS prophylaxis program. The overall median time of follow-up was 43 months. The overall CNS relapse rate was 6.3%; however, the incidence of CNS lymphoma presenting as the first isolated site of relapse in patients in otherwise complete remission (minimum follow-up of 19 months with 97% of patients off treatment) was only 1/58 (1.7%). Our data suggest that IT chemotherapy when given in combination with modern aggressive systemic combination chemotherapy, and without cranial radiation appears to be a highly effective modality for CNS prophylaxis regardless of stage, histology, or bone marrow or mediastinal involvement.

    Mature B-cell non-Hodgkin lymphoma (B-NHL) comprises more than 50% of all non-Hodgkin lymphoma (NHL) in children and adolescents. Many B-NHL subtypes frequently observed in adults are rarely diagnosed in children and adolescents. In this age group, Burkitt lymphoma (BL), Burkitt leukemia or FAB L3 leukemia (B-AL), diffuse large B-cell lymphoma (DLBCL), primary mediastinal large B-cell lymphoma (PMLBL), follicular lymphoma (FL), and aggressive mature B-NHL not further classifiable (B-NHL nfc) are the most common subtypes. Diverse clinical trials demonstrated similar results of current combination chemotherapy regimens succeeding in overall survival rates of more than 80%. However, treatment-related toxicity and the poor prognosis of relapse are serious concerns. Furthermore, specific histological B-NHL subtypes are rare in children and optimal treatment is not established. New treatment modalities are urgently needed for these patient groups. Rituximab, a monoclonal antibody that is already established in the treatment of adults with mature B-NHL, demonstrated promising results in pediatric patients. The definitive role of rituximab in the treatment of children and adolescents with B-NHL needs to be evaluated in prospective controlled clinical trials. This review provides a comprehensive overview of chemotherapy regimens and the perspectives for children and adolescents with mature B-cell lymphoma and leukemia. PMID:23570584

    Pediatric patients with newly diagnosed, non-Hodgkin Lymphoma (NHL) have an excellent overall survival. However, therapy regimens are associated with acute toxicity and late effects. Furthermore, patients with relapsed or refractory disease have relatively few options with proven clinical benefit. Both histologic and molecular differences exist between adult and pediatric NHL preventing simple translation of adult NHL successes into improvements in pediatric NHL treatment. This review summarizes the introduction of targeted therapies into frontline treatments for patients with anaplastic large-cell lymphoma and CD20-positive tumors, with the goal of improving overall survival while limiting both short- and long-term toxicities. In addition, newer approaches that have limited data in children but may have a significant role in how we treat pediatric NHL in the future are reviewed, which include CD19 directed therapy, Notch inhibition, the tri-functional antibody, FBTA05, and EZH2 inhibition.

    Differences in quality of life (QOL) of long-term survivors of aggressive or indolent subtypes of non-Hodgkin lymphoma (NHL) have not been frequently evaluated. We assessed these differences by analyzing results of a large QOL survey of long-term NHL survivors. We hypothesized that the incurable nature of indolent NHL would relate to worse QOL in long-term survivors while the potentially cured long-term survivors of aggressive lymphoma would have better QOL. We found that QOL was similar between the two groups. Results suggest that patients with indolent NHL are coping well with their disease, yet experience some overall feelings of life threat.

    Non-Hodgkin lymphoma (NHL) is a heterogeneous group of lymphoid malignancies accounting for a significant portion of cancers occurring in children, adolescents and young adults with an increasing incidence with age. The adolescent and young adult (AYA) population presents a specific set of characteristics and challenges. The most common diseases occurring in adolescents and young adults include Burkitt lymphoma, lymphoblastic lymphoma, diffuse large B-cell lymphoma, anaplastic large cell lymphoma and primary mediastinal B-cell lymphoma. There is also a higher incidence of primary central nervous system lymphoma in AYA patients. Cure rates largely depend on risk-stratification, and are generally superior to outcomes in comparison to older adult data but less than in younger children. Here, we review the unique clinical and biological characteristics of NHL occurring in the AYA population with a focus on how to achieve similar curative outcomes in AYA that have been established in younger cohorts.

    1990-02-01

    Some case-control studies have reported a significant association between occupational use of phenoxy herbicides and chlorophenols and soft-tissue sarcomas and malignant lymphomas. However, persons who spray or apply these substances are concomitantly exposed to other potentially carcinogenic chemicals and oncogenic viruses, which have been found or suspected to play a role in the etiology of these tumors. No study has thoroughly controlled for these other exposures, some of which have been shown to be independently associated with these tumors even after controlling for exposure to phenoxy acids or chlorophenols. On the other hand, it has been found that an observed risk from exposure to phenoxy herbicides disappeared on controlling for some of these concomitant exposures in the rare instance this was attempted. Also, on several occasions, an association has been observed with occupations in which exposure to phenoxys and chlorophenols may occur, but not with the compounds themselves. Accordingly, a detailed review of the evidence from occupational cohort studies was conducted, to see if it corroborates that from case-control studies. It was found that the evidence does not unequivocally incriminate phenoxys and chlorophenols as a cause of these tumors. The results obtained with cohort studies of sprayers and applicators do not corroborate the association reported among this occupational group, in case-control studies. It is possible that the suspected association may well be due, partly or wholly, to one or more of the other concomitant exposures. However, in view of the fact that the majority of the cohorts need further follow-up to be informative, it is concluded that further studies of these cohorts are required before it can be determined whether or not these tumors are caused by exposure to phenoxy acids and chlorophenols. 124 references.

    Many epidemiological studies provide solid evidence for an association of chronic hepatitis C virus (HCV) infection with B-cell non-Hodgkin's lymphoma (B-NHL). However, the most convincing evidence for a causal relationship between HCV infection and lymphoma development is the observation of B-NHL regression after HCV eradication by antiviral therapy (AVT). We conducted a literature search to identify studies that included patients with HCV-associated B-NHL (HCV-NHL) who received AVT, with the intention to treat lymphoma and viral disease at the same time. The primary end point was the correlation of sustained virological response (SVR) under AVT with lymphoma response. Secondary end points were overall lymphoma response rates and HCV-NHL response in correlation with lymphoma subtypes. We included 20 studies that evaluated the efficacy of AVT in HCV-NHL (n = 254 patients). Overall lymphoma response rate through AVT was 73% [95%>confidence interval, (CI) 67-78%]. Throughout studies there was a strong association between SVR and lymphoma response (83% response rate, 95%>CI, 76-88%) compared to a failure in achieving SVR (53% response rate, 95%>CI, 39-67%, P = 0.0002). There was a trend towards favourable response for AVT in HCV-associated marginal zone lymphomas (response rate 81%, 95%>CI, 74-87%) compared to nonmarginal zone origin (response rate 71%, 95%>CI, 61-79%, P = 0.07). In conclusion, in the current meta-analysis, the overall response rate of HCV-NHL under AVT justifies the recommendation for AVT as first-line treatment in patients who do not need immediate conventional treatment. The strong correlation of SVR and lymphoma regression supports the hypothesis of a causal relationship of HCV and lymphomagenesis. PMID:26924533

    Disorders of the cell cycle regulatory machinery play a key role in the pathogenesis of cancer. Over-expression of cyclin D1 protein has been reported in several solid tumors and certain lymphoid malignancies, but little is known about the effect of its expression on clinical behavior and outcome in B-cell Non-Hodgkin lymphoma (NHL). In this study, we investigated the expression of cyclin Dl in group of patients with NHL and correlated the results with the clinical and laboratory data. The degree of expression of cyclin Dl protein was evaluated by flow cytometry in a group of NHL patients (n = 46) and in normal control group (n = 10). Cyclin Dl over expression was detected in 10 out of 46 (21.7%) patients; they were 5/5-mantle cell lymphoma (MCL) (100%) and 5/28 large B-cell lymphoma (17.8%). All other NHL subtypes showed normal cyclin D1 expression. The clinical signs (hepatomegaly, splenomegaly and B-symptoms, clinical staging) and laboratory data (hemoglobin, white cell count (WBCs), platelet count, and bone marrow infiltration) were not significantly different between NHL subgroup with cyclin Dl over expression and that with normal cyclin Dl expression. Serum lactic dehydrogenase (LDH) levels and lymphadenopathy were significantly higher in NHL group with cyclin D1 over expression as compared to those without. Also, cyclin D1 over expression is associated with poor outcome of NHL patients. Cyclin Dl over expression was evident among all cases of MCL and few cases of large B-cell lymphoma. Cyclin Dl over expression might be used as adjuvant tool for diagnosis of MCL; has role in NHL biology and is bad prognostic index in NHL. PMID:17607588

Serum HBV and serum hepatitis C virus were measured in 471 NHL patients and 1,013 non-lymphoma cancer patients enrolled between February 2000 and March 2007. Furthermore, nested polymerase chain reaction of HBV-DNA was used to examine the sera from selected patients in these two populations and healthy volunteers for the presence of occult HBV infection. The infection rates (as indicated by the rates of HBsAg and occult HBV) were compared between different groups. There was a higher incidence of HBV infection in B cell NHL patients (23.5%), especially patients with diffuse large B lymphoma, than solid tumor patients (15.6%, P = 0.001). Among HbsAg-negative patients, those with B cell NHL had a higher prevalence of occult HBV infection (6%) than those with non-lymphoma solid tumors and healthy volunteers, 0% and 0.9%, respectively (P = 0.005). B cell NHL patients, even HBsAg-negative B cell NHL patients, but not T cell NHL patients, have a higher incidence of HBV infection than patients with solid tumors. Our findings support the etiologic role of HBV infection in B cell NHL. PMID:18327583

    Background To show magnetic resonance imaging (MRI) texture appearance change in non-Hodgkin lymphoma (NHL) during treatment with response controlled by quantitative volume analysis. Methods A total of 19 patients having NHL with an evaluable lymphoma lesion were scanned at three imaging timepoints with 1.5T device during clinical treatment evaluation. Texture characteristics of images were analyzed and classified with MaZda application and statistical tests. Results NHL tissue MRI texture imaged before treatment and under chemotherapy was classified within several subgroups, showing best discrimination with 96% correct classification in non-linear discriminant analysis of T2-weighted images. Texture parameters of MRI data were successfully tested with statistical tests to assess the impact of the separability of the parameters in evaluating chemotherapy response in lymphoma tissue. Conclusion Texture characteristics of MRI data were classified successfully; this proved texture analysis to be potential quantitative means of representing lymphoma tissue changes during chemotherapy response monitoring.

    Most national lymphoma registers rely on broad classifications which include Hodgkin and non-Hodgkin lymphomas (NHL), multiple myeloma and leukaemia. In Poland the National Histopathological Lymphoma Register project (NHLR) was implemented by hematopathologists in accordance with the 2008 WHO classification into haematopoietic and lymphoid tissues. We present the NHLR data and compare lymphoma distribution in Poland, Europe, as well as in North Central and South America. Records of 11718 patients diagnosed in 24 pathology departments from all over the country were retrieved and reclassified into indolent and aggressive lymphomas according to the 2008 revised WHO classification system. DLBCL (32.9%; 2587), CLL/SLL (31.84%; 2504) and MCL (9.04%; 711) were the three most frequent NHL. The ratio of indolent to aggressive NHL was 1.72; 63.25% (4809) to 36.25% (2794) of cases respectively. Multiple myeloma was less frequent as compared to the data from population-based national cancer register (13.32% vs. 28.94%). Major differences between NHLR and European and American data on NHL subtypes concered: higher incidence of aggressive B-cell lymphomas including DLBCL, lower FL and MALT incidence rate. The percentage of unclassified lymphomas in the study was minimal due to participation of hematopathologists. PMID:25031749

    Background The relative age effect (RAE) has been reported for a number of different activities. The RAE is the phenomena whereby players born in the first few months of a competition year are advantaged for selection to elite sports. Much of the literature has identified elite male athletics, such as the National Hockey League (NHL), as having consistently large RAEs. We propose that RAE may be lessened in the NHL since the last examination. Methods We examined demographic and selection factors to understand current NHL selection biases. Results We found that RAE was weak and was only evident when birth dates were broken into year halves. Players born in the first half of the year were relatively advantaged for entry into the NHL. We found that the RAE is smaller than reported in previous studies. Intraplayer comparisons for multiple factors, including place of birth, country of play, type of hockey played, height and weight, revealed no differences. Players who were not drafted (e.g., free agents) or who played university hockey in North America had no apparent RAE. Conclusion We found little evidence of an RAE in the current NHL player rosters. A larger study of all Canadian minor hockey intercity teams could help determine the existence of an RAE. PMID:24869606

    The mean nuclear area, maximum nuclear diameter (Dmax) and form factor (FF) have been measured in 30 specimens of non-Hodgkin's lymphoma (NHL) and 10 reactive lymph nodes, using the Reichert-Jung (Kontron) MOP-AMO3 image analyzer. Nuclear area and Dmax were found to be greater in high-grade NHL than in low-grade lymphomas and reactive nodes. In addition, there was close correlation between nuclear area and Dmax, especially for low-grade NHL and reactive specimens. As a means of distinguishing between high- and low-grade lymphomas, however, the FF appears to be of little value. PMID:6338055

    Diffuse Large B Cell Lymphomas (DLBCL) encompasses a heterogeneous group of tumors that together constitute the commonest of all Non Hodgkin Lymphoma (NHL) and the proclivity of DLBCL to oral cavity is unknown. They mostly arise from soft tissues as asymptomatic lesions, mostly without ‘B’ symptoms and involvement of jaw bones is uncommon. Most studies and case reports of oral DLBCL’s are based on, manifestation of primary extra-nodal disease or a component of a disseminated disease process involving regional lymph nodes. Many investigators have proposed that patients with this cell type who maintain a complete response for 24 consecutive months are cured because late relapses seldom occur. With advances in treatment modalities, many patients with NHL become long-term survivors and the risk of relapses or second tumors are of growing concern. We present a case of DLBCL which relapsed after five years of initial lesion in a 41 year old female patient and presented as a nonspecific bilateral anterior maxillary radiolucency. DLBCL usually express pan-B markers with small percentage expressing T-cell markers. Few rare cases of DLBCL have shown CD3 expression, which is a most sensitive T-cell marker which was focally expressed in the present case. PMID:27190967

    TRIM-NHL proteins are key regulators of developmental transitions, for example promoting differentiation, while inhibiting cell growth and proliferation, in stem and progenitor cells. Abnormalities in these proteins have been also associated with human diseases, particularly affecting muscular and neuronal functions, making them potential targets for therapeutic intervention. The purpose of this review is to provide a systematic and comprehensive summary on the most studied TRIM-NHL proteins, highlighting examples where connections were established between structural features, molecular functions and biological outcomes.

    Non-Hodgkin's lymphoma (NHL) is a rare tumor of the skull base. As the incidence of primary central nervous system (CNS) lymphoma has increased, atypical presentations involving the skull or cranial base exclusively have been reported. In immunocompetent patients with no previous history or predisposing factors, the diagnosis of primary NHL of the skull base may be delayed. We present four cases of nasal and paranasal sinus NHL with both skull base and intracranial involvement in immunocompetent patients. Clinicopathologic correlation suggests that cranial base and intracranial involvement with NHL represents advanced-stage primary sinonasal disease. Surgical biopsy before definitive treatment is recommended. Radiation therapy provides local control; adjuvant chemotherapy after primary radiation therapy may be required for recurrent disease.

    Primary lymphoma of the parotid gland is relatively rare and constitutes about 4-5% of extranodal lymphomas. The majority of them is non-Hodgkin lymphoma (NHL) and is B cell in nature. We report a case of primary diffuse large B-cell lymphoma (DLBCL) of the parotid gland in an elderly male. The case was diagnosed on fine needle aspiration cytology (FNAC) of the right parotid gland as high grade B-cell NHL and confirmed on histopathology as DLBCL. In correlation with the clinicoradiological findings, the case was diagnosed as primary parotid DLBCL. The case highlights the role of FNAC as a timely and useful diagnostic tool. PMID:27279690

    Except in primary effusion lymphoma (PEL), serous effusions with lymphomatous cells in non-Hodgkin lymphoma (NHL) are not frequently seen as first manifestation of disease. In NHL lymphoplasmacytic lymphoma (LPL) the spleen, lymph nodes, and bone marrow are frequently sites of disease and this type of NHL is usually associated with a serum paraprotein of IgM type accompanied by the clinical syndrome of Waldenström macroglobulinemia. Our patient with NHL LPL type presented in this report had less frequently seen involvement of gastrointestinal tract and clinically was first manifested as effusion in Douglas space. Cytological evaluation as well immunoanalyses of effusion in such cases is essential, and various ancillary studies, because of differential diagnostic problems of lymphomas in serous effusions, first include reactive lymphocytoses and small round-cell tumors (SRCT). In our patient, cytology of effusion revealed cytomorphologically atypical lymphomatous cells with plasmocytoid differentiation. Immunocytochemical and flow cytometry analysis confirmed lymphoid cell differentiation and pathohistological diagnosis of CD20(+) LPL was set after pathohistological analysis of resected ileum.

    Large and systematic studies of non-Hodgkin lymphoma (NHL) in the Far East (FE) with good comparative data are scarce in the literature. In this study, five expert hematopathologists classified 730 consecutive cases of newly-diagnosed NHL from four sites in the FE (excluding Japan) using the World Health Organization classification. The results were compared to 399 cases from North America (NA). We found a significantly higher male to female ratio in the FE compared to NA (1.7 versus 1.1; p < 0.05). The median ages of patients with low-grade (LG) and high-grade (HG) B-NHL in the FE (58 and 51 years, respectively) were significantly lower than in NA (64 and 68 years, respectively). The FE had a significantly lower relative frequency of B-NHL and a higher frequency of T-NHL (82 vs. 18 %) compared to NA (90.5 vs. 9.5 %). Among mature B cell lymphomas, the FE had a significantly higher relative frequency of HG B-NHL (54.8 %) and a lower frequency of LG B-NHL (27.2 %) than NA (34.3 and 56.1 %, respectively). Diffuse large B cell lymphoma was more common in the FE (49.4 %) compared to NA (29.3 %), whereas the relative frequency of follicular lymphoma was lower in the FE (9.4 %) compared to NA (33.6 %). Among T-NHL, nasal NK/T cell NHL was more frequent in the FE (5.2 %) compared to NA (0 %). Peripheral T cell lymphoma was also more common in the FE (9.1 %) than in NA (5.3 %). Further epidemiologic studies are needed to better understand the pathobiology of these differences. PMID:26537613

    The rationale to treat lymphomas with immunotherapy comes from long-standing evidence on their distinctive immune responsiveness. Indolent B-cell non-Hodgkin lymphomas, in particular, establish key interactions with the immune microenvironment to ensure prosurvival signals and prevent antitumor immune activation. However, reports of spontaneous regressions indicate that, under certain circumstances, patients develop therapeutic antitumor immunity. Several immunotherapeutic approaches have been thus developed to boost these effects in all patients. To date, targeting CD20 on malignant B cells with the antibody rituximab has been the most clinically effective strategy. However, relapse and resistance prevent to cure approximately half of B-NHL patients, underscoring the need of more effective therapies. The recognition of B-cell receptor variable regions as B-NHL unique antigens promoted the development of specific vaccines to immunize patients against their own tumor. Despite initial promising results, this strategy has not yet demonstrated a sufficient clinical benefit to reach the regulatory approval. Several novel agents are now available to stimulate immune effector functions or counteract immunosuppressive mechanisms, such as engineered antitumor T cells, co-stimulatory receptor agonist, and immune checkpoint-blocking antibodies. Thus, multiple elements can now be exploited in more effective combinations to break the barriers for the induction of anti-lymphoma immunity. PMID:26388871

    An otherwise healthy 57-year-old man was found to have an early stage, high-grade, non-Hodgkin's lymphoma (NHL) of the spermatic cord. A plan of treatment involving surgery, radiation therapy, combination chemotherapy, and central nervous system prophylaxis was recommended. He did not complete the recommended treatment plan, and subsequently returned with recurrent tumor in his brain. This case highlights the similarity of spermatic cord NHL to primary NHL of the testicle, and the propensity of both to progress or relapse in nodal and extranodal patterns. PMID:8604473

    Introduction B-cell Non-Hodgkin lymphomas (B-NHLs) include a number of disease subtypes, each defined by the tempo of disease progression and the identity of the cancerous cell. Idelalisib is a potent, selective inhibitor of the delta isoform of phosphatidylinositol-3-kinase (PI3K), a lipid kinase whose over-activity in B-NHL drives disease progression. Idelalisib has demonstrated activity in indolent B-NHL (iB-NHL) and is approved for use as monotherapy in patients with follicular lymphoma and small lymphocytic lymphoma and in combination with rituximab in patients with chronic lymphocytic leukemia. Areas Covered Herein we review the development and pharmacology of idelalisib, its safety and efficacy in clinical studies of iB-NHL, and its potential for inclusion in future applications in iB-NHL and in combination with other therapies. Expert Opinion Idelalisib adds to the growing arsenal of iB-NHL pharmacotherapeutics and to the progression of the field toward precision agents with good efficacy and reduced toxicities. Nevertheless, idelalisib carries important risks that require careful patient counseling and monitoring. The appropriate sequencing of idelalisib with other proven treatment options in addition to its potential for combination with established or novel drugs will be borne out in ongoing and planned investigations.

    Although agents targeting B-cell receptor signaling have provided practice-changing results in relapsed chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma (NHL), they require prolonged administration and provide incomplete responses. Given synergistic preclinical activity with phosphatidylinositol 3-kinase δ and spleen tyrosine kinase inhibition, this phase 2 study evaluated the safety and efficacy of the combination of idelalisib and entospletinib. Eligible patients with relapsed or refractory CLL or NHL underwent intrapatient dose escalation with each agent. With a median treatment exposure of 10 weeks, 60% and 36% of patients with CLL or follicular lymphoma, respectively, achieved objective responses. However, the study was terminated early because of treatment-emergent pneumonitis in 18% of patients (severe in 11 of 12 cases). Although most patients recovered with supportive measures and systemic steroids, 2 fatalities occurred and were attributed to treatment-emergent pneumonitis. Increases of interferon-γ and interleukins 6, 7, and 8 occurred over time in patients who developed pneumonitis. Future studies of novel combinations should employ conservative designs that incorporate pharmacodynamics/biomarker monitoring. These investigations should also prospectively evaluate plasma cytokine/chemokine levels in an attempt to validate biomarkers predictive of response and toxicity. This trial was registered at www.clinicaltrials.gov as #NCT01796470. PMID:26968534

    Myeloablative autologous hematopoietic stem cell transplantation (HSCT) is a mainstay of therapy for relapsed intermediate-grade B-cell non-Hodgkin lymphoma (NHL); however, relapse rates are high. In phase 1 studies designed to improve long-term remission rates, we administered adoptive T-cell immunotherapy after HSCT, using ex vivo-expanded autologous central memory-enriched T cells (TCM) transduced with lentivirus expressing CD19-specific chimeric antigen receptors (CARs). We present results from 2 safety/feasibility studies, NHL1 and NHL2, investigating different T-cell populations and CAR constructs. Engineered TCM-derived CD19 CAR T cells were infused 2 days after HSCT at doses of 25 to 200 × 10(6) in a single infusion. In NHL1, 8 patients safely received T-cell products engineered from enriched CD8(+) TCM subsets, expressing a first-generation CD19 CAR containing only the CD3ζ endodomain (CD19R:ζ). Four of 8 patients (50%; 95% confidence interval [CI]: 16-84%) were progression free at both 1 and 2 years. In NHL2, 8 patients safely received T-cell products engineered from enriched CD4(+) and CD8(+) TCM subsets and expressing a second-generation CD19 CAR containing the CD28 and CD3ζ endodomains (CD19R:28ζ). Six of 8 patients (75%; 95% CI: 35-97%) were progression free at 1 year. The CD4(+)/CD8(+) TCM-derived CD19 CAR T cells (NHL2) exhibited improvement in expansion; however, persistence was ≤28 days, similar to that seen by others using CD28 CARs. Neither cytokine release syndrome nor delayed hematopoietic engraftment was observed in either trial. These data demonstrate the safety and feasibility of CD19 CAR TCM therapy after HSCT. Trials were registered at www.clinicaltrials.gov as #NCT01318317 and #NCT01815749. PMID:27118452

    Dramatic increase in hand-held cellular telephone use since the 1980s and excess risk of lymphoproliferative malignancies associated with radio-frequency radiation (RFR) exposures in epidemiological and experimental studies motivated assessment of cellular telephones within a comprehensive US case-control investigation of non-Hodgkin lymphoma (NHL). A questionnaire ascertained cellular telephone use in 551 NHL cases and 462 frequency-matched population controls. Compared to persons who had never used cellular telephones, risks were not increased among individuals whose lifetime use was fewer than 10 (odds ratio (OR) = 0.9, 95% confidence intervals (CI): 0.6, 1.3), 10-100 (OR = 1.0, 95 % CI: 0.7, 1.5) or more than 100 times (e.g., regular users, OR = 0.9, 95% CI: 0.6, 1.4). Among regular users compared to those who had never used hand-held cellular telephones, risks of NHL were not significantly associated with minutes per week, duration, cumulative lifetime or year of first use, although NHL was non-significantly higher in men who used cellular telephones for more than 8 years. Little evidence linked use of cellular telephones with total, diffuse large B-cell lymphoma or follicular NHL. These findings must be interpreted in the context of less than 5% of the population reporting duration of use of 6 or more years or lifetime cumulative use of 200 or more hours. PMID:16894556

    CD43 expression on B cells is an immunophenotypic feature suggestive of malignancy. In the light of its diagnostic importance, we performed a comprehensive survey of CD43 expression in various types of non-Hodgkin lymphoma (NHL) and determined the frequency of its expression in routinely fixed paraffin-embedded tissues. Tissue sections in 742 cases of NHL, pretreated by the heat-induced epitope retrieval technique, were immunostained using an anti-CD43 antibody. Three categories of CD43 positivity were found: (1) more than 90% of T-cell lymphoma, mantle cell lymphoma, B-cell small lymphocytic lymphoma, and Burkitt lymphoma cases were positive; (2) 20% to 40% of nodal and extranodal marginal zone lymphoma (MZL), diffuse large B-cell lymphoma, Burkitt-like B-cell lymphoma, and lymphoplasmacytoid lymphoma cases were positive; and (3) 0% to 6% of primary splenic MZL and various types of follicular lymphoma cases were positive. Most CD43+ follicular lymphomas were predominantly large cell type with focally diffuse areas; their follicular center cell origin in 4 of 8 cases was supported by the presence of CD10 immunoreactivity and/or t(14;18) fusion gene product. CD43 is frequently detectable in a subset of B-NHL, and, thus, it seems to be a highly sensitive marker for these tumors. CD43 also may be a useful marker for classifying B-cell NHLs by virtue of its differential expression in these tumors. PMID:10191768

    Introduction Bortezomib, the first proteasome inhibitor (PI) to be evaluated in humans, is approved in the USA and Europe for the treatment of patients with multiple myeloma, and in the USA for patients with relapsed mantle cell lymphoma (MCL). Areas covered This review examines the role of bortezomib in the therapy of non-Hodgkin’s lymphoma (NHL). Bortezomib may be particularly effective against the NF-κB-dependent activated B-cell subtype of diffuse large B-cell lymphoma. The combination of bortezomib with rituximab and dexamethasone represents a standard approach for the treatment of Waldenström’s macroglobulinemia, and that with bendamustine and rituximab has demonstrated excellent efficacy in follicular lymphoma. Combinations with other novel agents, such as inhibitors of cyclin-dependent kinases or histone deacetylases, also hold substantial promise in NHL. Unmet needs in NHL, competitor compounds, chemistry, pharmacokinetics, pharmacodynamics and safety and tolerability of bortezomib are also discussed. Expert opinion The success of bortezomib in MCL has validated the proteasome as a therapeutic target in NHL. Rational combinations, for example, with Bruton’s tyrosine kinase inhibitors or BH3-mimetics, may hold the key to optimizing the therapeutic potential of PIs in NHL. Future trials are likely to involve newer agents with improved pharmacodynamic (e.g., carfilzomib, marizomib) or pharmacokinetic (e.g., ixazomib, oprozomib) properties. PMID:25263936

    Reports of the presence of Borrelia burgdorferi DNA in malignant lymphomas have raised the hypothesis that infection with B burgdorferi may be causally related to non-Hodgkin lymphoma (NHL) development. We conducted a Danish-Swedish case-control study including 3055 NHL patients and 3187 population controls. History of tick bite or Borrelia infection was ascertained through structured telephone interviews and through enzyme-linked immunosorbent assay serum analyses for antibodies against B burgdorferi in a subset of 1579 patients and 1358 controls. Statistical associations with risk of NHL, including histologic subtypes, were assessed by logistic regression. Overall risk of NHL was not associated with self-reported history of tick bite (odds ratio [OR] = 1.0; 95% confidence interval: 0.9-1.1), Borrelia infection (OR = 1.3 [0.96-1.8]) or the presence of anti-Borrelia antibodies (OR = 1.3 [0.9-2.0]). However, in analyses of NHL subtypes, self-reported history of B burgdorferi infection (OR = 2.5 [1.2-5.1]) and seropositivity for anti-Borrelia antibodies (OR = 3.6 [1.8-7.4]) were both associated with risk of mantle cell lymphoma. Notably, this specific association was also observed in persons who did not recall Borrelia infection yet tested positive for anti-Borrelia antibodies (OR = 4.2 [2.0-8.9]). Our observations suggest a previously unreported association between B burgdorferi infection and risk of mantle cell lymphoma. PMID:18424667

    T lymphocyte non-Hodgkin's lymphoma (T-NHL) represents an aggressive and largely therapy-resistant subtype of lymphoid malignancies. As deregulated apoptosis is a frequent hallmark of lymphomagenesis, we analyzed gene expression profiles and protein levels of primary human T-NHL samples for various apoptotic regulators. We identified the apoptotic regulator MCL-1 as the only pro-survival BCL-2 family member to be highly expressed throughout all human T-NHL subtypes. Functional validation of pro-survival protein members of the BCL-2 family in two independent T-NHL mouse models identified that the partial loss of Mcl-1 significantly delayed T-NHL development in vivo. Moreover, the inducible reduction of MCL-1 protein levels in lymphoma-burdened mice severely impaired the continued survival of T-NHL cells, increased their susceptibility to chemotherapeutics and delayed lymphoma progression. Lymphoma viability remained unaffected by the genetic deletion or pharmacological inhibition of all alternative BCL-2 family members. Consistent with a therapeutic window for MCL-1 treatment within the context of the whole organism, we observed an only minimal toxicity after systemic heterozygous loss of Mcl-1 in vivo. We conclude that re-activation of mitochondrial apoptosis by blockade of MCL-1 represents a promising therapeutic strategy to treat T-cell lymphoma. PMID:27055871

    Relation between Epstein-Barr virus (EBV) and nasopharyngeal carsinoma, Burkitt's lymphoma, and lymphomas in immunosupressed patients have been shown previously in different studies. The same relationship was also shown in Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) by some researchers. The aim of this study was to demonstrate EBV nucleic acids in tissue sections of adult patients with lymphoma. The presence of EBV encoded RNA (EBER) were investigated with in situ hybridization and EBV-DNA with PCR method in 29 formalin-fixed paraffin-embedded tissue sections (19 lymph nodes, the others being gastric, orbital, skin, salivary gland, testicle, small intestinal, tongue root, bone marrow and gingival tissues) of 8 patients with HL and 21 patients with NHL who were followed-up in Haematology Clinics of our university hospital. EBER and EBV-DNA positivity rates were found as follows respectively; 50% (n: 4) and 37.5% (n: 3) of 8 HL patients, and 23.8% (n: 5) and 47.6% (n: 10) of 21 NHL patients. In total evaluation EBER and/or EBV-DNA were positive in 5 of 8 (62.5%) HL, and 12 of 21 (57.1%) NHL tissue sections. There was no significant difference in EBER and EBV-DNA positivity between HL and NHL groups. As a result, our study emphasize a possible EBV related aetiology in HL and NHL. PMID:16544549

    Lymphomas are one of the commonest malignancies in adolescents and young adults (AYA) accounting respectively for 22% of all cancers in patients aged 15-24 years (16% for Hodgkin lymphoma (HL) and 6% for non-HL (NHL)). The distribution of NHL subtypes in this age group differs strikingly from the distribution in children and in older adults with 4 main subtypes accounting for the majority of the cases: diffuse large B-cell lymphoma (DLBCL) including primary mediastinal B-cell lymphoma, Burkitt lymphoma, lymphoblastic lymphoma or anaplastic large cell lymphoma. Age-related differences in tumor biology have been demonstrated mainly in DLBCL but there is still a need for biological studies to better understand age-related differences in this age group. AYA patients currently diagnosed with HL and NHL have 5-year survival expectations exceeding 90 and 75%, respectively. Different therapeutic strategies are often used in children and adult lymphoma and the dispersion of lymphoma care between adult and pediatric hematologist-oncologists results in heterogeneous strategies for each subgroup according to age. The impact of these different strategies on outcomes is not easy to evaluate given the paucity of population-based data focused on this age group, taking into account tumor biology and the lack of a uniform staging system. Given the excellent results obtained with current therapies, the challenge now is to develop strategies aimed at reducing acute and long-term toxicity in most patients while maintaining high cure rates and to identify patients at high risk of failure requiring new strategies including more selective targeted therapies.

    Follicular lymphomas (FL) are among the most common non-Hodgkin's lymphoma (NHL) in adults. However, they are rare in children making up less than 3% of paediatric NHL cases. They occur most commonly in the head and neck region, lymph nodes or tonsils, with occasional extra-nodal occurrences. Distinction of FL from potentially clonal but, reactive follicular hyperplasia is important. We report a case of a 6-year-old male child presenting with night stridor since 6 months. Clinical examination revealed asymmetrical enlargement of the left tonsil. Routine left tonsillectomy was performed and the specimen was sent for histopathological examination. Diagnosis of follicular lymphoma was made on histopathological examination and further confirmed by immunohistochemistry. PMID:23188842

    The aim of the present study was to investigate the expression and localization of B-cell lymphoma-2 (Bcl-2) in the oviduct of the Chinese soft-shelled turtle, Pelodiscus sinensis, during the reproductive cycle to analyze the relationship between Bcl-2 and sperm storage. Bcl-2 expression was confirmed in the P. sinensis oviduct by western blot analysis. Hematoxylin-eosin staining showed that female P. sinensis stored sperm from November to April of the following year. The oviduct showed positive immunostaining for Bcl-2 of epithelial ciliated cells, gland ducts, and gland cells. Bcl-2 expression in the oviduct was associated with sperm storage occurrence. This indicates that the survival factor Bcl-2 may play a role in P. sinensis sperm storage. PMID:26285642

    Agent Orange was the most common herbicide used in the Second Indochina War in the course of military operations in the former South Vietnam. Agent Orange is contaminated by the carcinogen 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD) in mean concentrations of 2 mg/kg. After much dispute of a causal association between exposure to herbicides containing TCDD and occurrence of soft-tissue sarcoma and non-Hodgkin lymphoma, two simultaneous case-control studies were set up in Vietnam to examine possible relationships. Subject recruitment is ongoing, with target numbers of 150 cases of soft-tissue sarcoma and 150 cases of non-Hodgkin lymphoma and diagnoses at the Cancer Center at Ho Chi Minh City, Vietnam. Two hospital controls are matched to each case. As in other studies of cancer in persons occupationally or otherwise exposed to herbicides and their contaminants, evaluation of past exposure of the recruited subjects is among the most complicated issues. Because accurate records are usually unavailable, surrogate measures of likely exposure are often calculated. As a first approach in our studies we used the Stellman and Stellman exposure index. The index is based on matching subjects' history of residence and the information on times and locations of Agent Orange spraying recorded on HERBS tape by the U.S. Army and taking into account the distance from the spraying as well as environmental and biologic half-life of TCDD. The exposure index is calculated in two centers, New York and Hanoi, with slightly different assumptions. In addition, samples of body tissues from the subjects (20 ml blood, 2 g adipose tissue, and tumor sections in paraffin blocks) are taken and stored. Their future analysis will provide additional source of exposure assessment. Strengths and weaknesses of both exposure measures are discussed in this paper. PMID:9599715

    Intrabony oral non-Hodgkin lymphoma (NHL) is rare. We report 2 cases of NHL of the maxilla that initially presented as apical abscesses in endodontically treated teeth. Radiographic findings were nondescript, but tissue biopsy revealed diffuse large B-cell NHL in both instances. No other sites of disease were found. Both patients were treated by chemotherapy and radiation with good results. As primary NHL of the maxilla can mimic a dental inflammatory lesion, tissue biopsy is mandatory in cases where symptoms do not resolve after specific treatment. PMID:24059491

    Farming and pesticide use have previously been linked to non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL) and multiple myeloma (MM). We evaluated agricultural use of specific insecticides, fungicides, and fumigants and risk of NHL and NHL-subtypes (including CLL and MM) in a U.S.-based prospective cohort of farmers and commercial pesticide applicators. A total of 523 cases occurred among 54,306 pesticide applicators from enrollment (1993–97) through December 31, 2011 in Iowa, and December 31, 2010 in North Carolina. Information on pesticide use, other agricultural exposures and other factors was obtained from questionnaires at enrollment and at follow-up approximately five years later (1999–2005). Information from questionnaires, monitoring, and the literature were used to create lifetime-days and intensity-weighted lifetime days of pesticide use, taking into account exposure-modifying factors. Poisson and polytomous models were used to calculate relative risks (RR) and 95% confidence intervals (CI) to evaluate associations between 26 pesticides and NHL and five NHL-subtypes, while adjusting for potential confounding factors. For total NHL, statistically significant positive exposure-response trends were seen with lindane and DDT. Terbufos was associated with total NHL in ever/never comparisons only. In subtype analyses, terbufos and DDT were associated with small cell lymphoma/chronic lymphocytic leukemia/marginal cell lymphoma, lindane and diazinon with follicular lymphoma, and permethrin with MM. However, tests of homogeneity did not show significant differences in exposure-response among NHL-subtypes for any pesticide. Because 26 pesticides were evaluated for their association with NHL and its subtypes, some chance finding could have occurred. Our results showed pesticides from different chemical and functional classes were associated with an excess risk of NHL and NHL subtypes, but not all members of any single class of pesticides were

    The non-Hodgkin lymphomas (NHLs) of childhood include high-grade mature B cell lymphoma [Burkitt lymphoma (BL), diffuse large B cell lymphoma (DLBCL), and primary mediastinal large B cell lymphoma (PMLBCL)], anaplastic large cell lymphoma (ALCL), and lymphoblastic lymphoma (LL). The prognosis for children with NHL is generally excellent, although there are some higher risk groups. In this regard, PMLBCL is generally associated with a poorer outcome than BL or DLBCL of comparable stage. The long-term event-free survival for children with ALCL is approximately 70 %. Novel biological agents, including those that target CD-30 or ALK, may hold promise for improving treatment results. Children with LL are treated with regimens derived from those used to treat acute lymphoblastic leukemia (ALL). Recent biological study of LL may provide insights into revising treatment stratification. The challenge in pediatric NHL, a group that already has a relatively good prognosis, is to improve treatment outcome without increasing concerning late effects. PMID:26174528

    2014-01-01

    Non-Hodgkin lymphoma (NHL) is one of the most common hematologic malignancies worldwide. The incidence of NHL has been rising for several decades; however, in the last 20 years, it reached a plateau. NHL incidence among males is significantly higher than in females. In addition to gender itself, gravidity has a protective role against NHL occurrence. Gender also matters in terms of NHL clinical characteristics. For example, female predominance was found in three extra-nodal sites (the breast, thyroid, and the respiratory system) occasionally involved in NHL. The diagnosis of NHL during pregnancy is associated with a unique clinical behavior. It is usually diagnosed in the second or third trimester and in advanced stage. Furthermore, the histological subtype is highly aggressive, and reproductive organ involvement is common. The reduced rate of NHL among females may be explained by direct effects of estrogens on lymphoma cell proliferation or by its effect on anti-tumor immune response. Gender has an important role in responsiveness to standard B cell NHL treatment. Among older adults, women benefited more from the addition of the anti-CD20 antibody rituximab to standard chemotherapy regimens. This phenomenon can be explained by the difference in clearance rate of rituximab that was found to be significantly lower among older females than older males. In mantle cell lymphoma, women receiving lenalidomide have higher rates of response. An understanding of the mechanisms responsible for gender-associated NHL differences will ultimately improve the clinical approach, allowing for a more accurate assessment of prognosis and patient-tailored treatment.

    To evaluate the efficacy and feasibility of upfront high-dose chemotherapy (HDCT) and rituximab (R) followed by autologous peripheral blood stem cell transplantation (auto-PBSCT) in patients with newly diagnosed high-intermediate(HI)-, and high(H)-risk diffuse large B-cell lymphoma (DLBCL), we conducted a multicenter prospective phase II trial. In 15-60-year-old patients with H- or HI-risk DLBCL, after three courses of (R-)CHOP14, high-dose etoposide was given prior to peripheral blood stem cell harvesting. After an additional three courses of (R-)CHOP14, auto-PBSCT was performed following HDCT. The primary endpoint of the study is progression-free survival (PFS) at 2 years after registration in eligible patients. The expected PFS and the threshold PFS were estimated to be 70 and 50 %, respectively. Among 40 eligible patients registered, 30 patients completed treatment. With a median observation period in surviving eligible patients of 63 months, the 2- and 4-year PFS after registration were 79.9 and 72.0 %, respectively. The 2- and 4-year overall survival (OS) were 92.5 and 84.6 %, respectively. In 30 patients who completed treatment, the 4-year PFS and OS after auto-PBSCT were 79.2 and 85.9 %, respectively. In conclusion, the results of our study suggest that upfront HDCT and auto-PBSCT combined with rituximab is highly effective as an initial treatment for HI-, and H-risk DLBCL. PMID:27084252

    Primary hepatic lymphoma (PHL) is a lymphoproliferative disorder confined to the liver without evidence of involvement of spleen, lymph nodes, bone marrow or other lymphoid structures. This is in contrast to Non Hodgkin's Lymphoma (NHL) that often involves the liver as a secondary manifestation. PHL is a rare disease and constitutes 0.016% of all cases of NHL. PHL typically occurs in middle aged men, and usually the chief presenting symptoms are non specific which includes right upper quadrant pain, B symptoms like fever and weight loss and constitutional symptoms. Most frequent physical finding is hepatomegaly which occurs in 75% of patients. Jaundice is rare and present only in less than 5% of patients. Majority of PHL originates from B cells. The blood investigations and imaging findings are nonspecific. Histopathology is essential and confirms the diagnosis. Treatment modalities include combination of surgical resection, chemotherapy and radiotherapy. The prognosis without therapy is grim. The prognosis and management of PHL is different from hepatocellular carcinoma or metastatic disease, hence it is essential to differentiate it from these diseases. The purpose of this review is to emphasize the importance of accurate diagnosis before implementing therapeutic plan for any hepatic space occupying lesion in liver. PMID:26591949

The majority of the HIV-infected patients with NHL present with advanced stage extranodal disease of the B-cell phenotype. Lymphomas are the second most common tumors involving the heart in HIV-infected patients. Although the heart may serve as the primary focus of the lymphoma, in most HIV-related cases, cardiac lymphomatous involvement is part of a metastatic process that originated elsewhere.

    Non-Hodgkin B-cell lymphoma (B-NHL) are aggressive lymphoid malignancies that develop in patients due to oncogenic activation, chemo-resistance, and immune evasion. Tumor biopsies show that B-NHL frequently uses several immune escape strategies, which has hindered the development of checkpoint blockade immunotherapies in these diseases. To gain a better understanding of B-NHL immune editing, we hypothesized that the transcriptional hallmarks of immune escape associated with these diseases could be identified from the meta-analysis of large series of microarrays from B-NHL biopsies. Thus, 1446 transcriptome microarrays from seven types of B-NHL were downloaded and assembled from 33 public Gene Expression Omnibus (GEO) datasets, and a method for scoring the transcriptional hallmarks in single samples was developed. This approach was validated by matching scores to phenotypic hallmarks of B-NHL such as proliferation, signaling, metabolic activity, and leucocyte infiltration. Through this method, we observed a significant enrichment of 33 immune escape genes in most diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL) samples, with fewer in mantle cell lymphoma (MCL) and marginal zone lymphoma (MZL) samples. Comparing these gene expression patterns with overall survival data evidenced four stages of cancer immune editing in B-NHL: non-immunogenic tumors (stage 1), immunogenic tumors without immune escape (stage 2), immunogenic tumors with immune escape (stage 3), and fully immuno-edited tumors (stage 4). This model complements the standard international prognostic indices for B-NHL and proposes that immune escape stages 3 and 4 (76% of the FL and DLBCL samples in this data set) identify patients relevant for checkpoint blockade immunotherapies.

    A variety of evidence suggests that estrogens may induce non-Hodgkin lymphoma (NHL). The reaction of catechol estrogen quinones with DNA to form depurinating estrogen-DNA adducts is hypothesized to initiate this process. These adducts are released from DNA, shed from cells into the bloodstream and excreted in urine. The aim of this study was to determine whether or not the depurinating estrogen-DNA adducts might be involved in the aetiology of human NHL. Estrogen metabolites, conjugates and depurinating DNA adducts were identified and quantified in spot urine samples from 15 men with NHL and 30 healthy control men by using ultraperformance liquid chromatography/tandem mass spectrometry. The levels of estrogen-DNA adducts were significantly higher in the men with NHL than in the healthy control men. Thus, formation of estrogen-DNA adducts may play a critical role in the aetiology of NHL, and these adducts could be potential biomarkers of NHL risk. PMID:19863189

    Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) often present with systemic symptoms such as fatigue, shortness of breath and night sweats, mimicking pregnancy-related features which may result in delayed disease diagnosis. Furthermore, the wish to avoid investigational imaging, aiming to protect the fetus from radiation exposure, may lead to a further delay, which does not often result in significant changes in HL clinical nature and patient outcome. In contrast, a more aggressive behavior (i.e., advanced disease stage and reproductive organ involvement) of most NHL types diagnosed in pregnancy may require urgent therapeutic intervention to prevent disease progression. Current management of pregnancy-associated NHL depends on histological subtype of the disease, gestational stage at diagnosis and the urgency of treatment for a specific patient. Patients diagnosed with indolent lymphoma may often be just followed, whereas those presenting with aggressive or highly aggressive disease need to be urgently treated with chemoimmunotherapy, either after undergoing an elective pregnancy termination if diagnosed at an early gestational stage, or with pregnancy preservation, if diagnosed later. Supportive care of NHL is also important; however, granulocyte colony stimulating factor (G-CSF) which is commonly used outside of pregnancy, should be cautiously employed, considering its established teratogenicity in animals, though this is less proven in humans. In conclusion, given the paucity of studies prospectively evaluating the outcome of pregnant women with NHL, international efforts are warranted to elucidate critical issues and develop guidelines for the management of such patients.

    The association of a monoclonal gammopathy (MG) with a B cell non-Hodgkin's lymphoma (NHL) is a well-known phenomenon. It has been recognized in many subtypes of primary gastrointestinal lymphoma but its association with primary colonic mantle cell lymphoma has never been yet described. We report a 65-year-old man who presented with an exudative ascites and constipation. Serum electrophoresis showed a monoclonal peak in the gamma region of 45g/L and immunoelectrophoresis confirmed the presence of monoclonal gammopathy of IgM kappa type. Bone marrow aspirate was normal. Radiologic and endoscopic investigations evidenced a primary colonic mantle cell lymphoma. Although the association of an MG with an NHL and, in particular, to a primitive digestive location appears a rare phenomenon, endoscopic investigations in patients with MG appears legitimate in the presence of any digestive sign.

    Objective: To report an unusual case of systemic non-Hodgkin lymphoma (NHL) with repeated relapse in the lacrimal glands, in spite of complete remission for several years after treatment. Methods: A 78-year-old male with small lymphocytic B cell NHL, stage IV disease (lung invasion), was submitted to surgery and chemotherapy in 2001, with complete remission of the disease. In 2003 he developed a nodular lesion in the right lacrimal fossa. Pathology results revealed a local relapse of NHL. Radiation and chemotherapy were initiated and complete remission was again achieved. In 2012 the patient developed a new nodular lesion located in the left lacrimal fossa, resulting in diplopia, ptosis and proptosis of the left eye. Orbital computerized tomography (CT), ocular ultrasound and incisional biopsy were performed. Results: Orbital CT revealed a lesion infiltrating the left lacrimal gland and encircling the globe. Biopsy results confirmed a local relapse of B cell NHL. The patient was submitted to local radiation therapy with progressive resolution of ptosis, proptosis and diplopia. Response to treatment was monitored with ocular ultrasound. Conclusions: Patients with NHL diagnosis should be immediately investigated if ophthalmic or orbital symptoms develop. NHL extension to the orbit and adnexa is infrequent (5% of NHL cases) but may occur at any stage of the disease, including as a relapse site. In such cases, radiation and chemotherapy achieve good results, inducing long periods of remission.

    B-cell non-Hodgkin's lymphoma (B-NHL) is a well-documented complication of hepatitis C virus (HCV) infection. Marginal zone (mucosa-associated lymphoid tissue; MALT) lymphomas constitute a less common type of B-NHL. In this article, we report a case of liver MALT in a cirrhotic patient, incidentally discovered after liver transplantation (LT). We discuss pertinent diagnostic and management strategies in this clinical setting. PMID:15973702

    Non-Hodgkin’s lymphomas (NHL) are a heterogeneous group of lymphoproliferative disorders originating in B lymphocytes, T lymphocytes, or natural killer cells. Mantle cell lymphoma (MCL) accounts for approximately 6% of all newly diagnosed NHL cases. Radiation therapy with or without systemic therapy is a reasonable approach for the few patients who present with early-stage disease. Rituximab-based chemoimmunotherapy followed by high-dose therapy and autologous stem cell rescue (HDT/ASCR) is recommended for patients presenting with advanced-stage disease. Induction therapy followed by rituximab maintenance may provide extended disease control for those who are not candidates for HDT/ASCR. Ibrutinib, a Bruton tyrosine kinase inhibitor, was recently approved for the treatment of relapsed or refractory disease. This manuscript discusses the recommendations outlined in the NCCN Guidelines for NHL regarding the diagnosis and management of patients with MCL. PMID:25190696

    The current study reports the case of a patient with Philadelphia chromosome-negative (Ph−) non-Hodgkin's lymphoma (NHL) and chronic phase (CP) Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML) that also possessed characteristic enlarged lymph nodes. A lymph node biopsy resulted in the diagnosis of CP-CML, in addition to T-lymphoblastic cell NHL with negative break point cluster/Abelson tyrosine kinase fusion genes in the lymph node of the patient, which was diagnosed as Ph− NHL. A review of the literature was performed in the present study to investigate the genetic differences between Ph− NHL and Ph+ NHL in patients with CML. The median age of patients with NHL and CML was 41 years. The follow-up time of patients with Ph+ NHL was significantly shorter (mean, <6 months) compared to the follow-up time of patients with Ph− NHL (mean, >15 months). Therefore the present study concludes that Ph+ NHL may be more aggressive compared with Ph+ NHL. The present study suggests that additional studies are required to assess the clinical and genetic characteristics of NHL patients with CML. PMID:27073575

    Great advances have been made in the treatment of paediatric non-Hodgkin lymphoma (NHL). In high-income countries (HIC), cure rates now exceed 85%. However, in low- and middle-income countries (LMIC), cure rates remain less than 50%. It is estimated that over 90% of paediatric NHL worldwide occur in LMIC; therefore, even modest improvements in outcome would have significant impact in reducing the burden of paediatric NHL globally. This article will discuss some of the issues required to improve the outcome of paediatric NHL in LMIC using data presented at the Fifth International Symposium on Childhood, Adolescent and Young Adult Non-Hodgkin Lymphoma held in Varese, Italy, 2015 to illustrate these issues. Additionally, potential bi-directional benefits for patients in both LMIC and HIC from future collaborations will be discussed. PMID:27098084

    Ocular adnexal non-Hodgkin’s lymphoma (NHL), the most common form of ophthalmic NHL, has a unique incidence pattern showing a steady and rapid increase in the past few decades, nearly equal rates among both genders, and predominance among Asians/Pacific Islanders. No major cause for ocular adnexal NHL has been identified, although infectious agents, immune disorders and genetic/epigenetic factors have all been implicated in its etiology. Identifying putative risk factors and biologic mechanisms leading to carcinogenesis in ocular adnexal NHL may enable implementation of effective preventive and/or therapeutic approaches for this malignancy. This article summarizes current knowledge on epidemiology of ocular adnexal NHL and the role of various potential risk factors in its etiology. PMID:23976898

    Non-Hodgkin lymphomas (NHLs) are a diverse group of blood cancers derived from lymphocytes that vary significantly in their severity. Surgery is not often used as a treatment because of the efficacy of chemotherapy, biological therapy, radiotherapy and hematopoietic stem cell transplantation. We reviewed the natural history and possible role of surgery for NHL. Surgery may be useful in confirming or refuting an equivocal radiological diagnosis through biopsy, removing symptomatic limited disease from an affected organ and in splenectomy for primary splenic lymphoma. Emergency abdominal surgery for acute complications of NHL provides palliation and diagnosis. There is as yet no consensus as to the optimum treatment for symptomatic limited disease affecting an organ and timing of chemotherapy perioperatively. Prospective randomized trials are required.

    Evidence from a small number of studies suggests that longer telomere length measured in peripheral leukocytes is associated with an increased risk of non-Hodgkin lymphoma (NHL). However, these studies may be biased by reverse causation, confounded by unmeasured environmental exposures and might miss time points for which prospective telomere measurement would best reveal a relationship between telomere length and NHL risk. We performed an analysis of genetically inferred telomere length and NHL risk in a study of 10 102 NHL cases of the four most common B-cell histologic types and 9562 controls using a genetic risk score (GRS) comprising nine telomere length-associated single-nucleotide polymorphisms. This approach uses existing genotype data and estimates telomere length by weighing the number of telomere length-associated variant alleles an individual carries with the published change in kb of telomere length. The analysis of the telomere length GRS resulted in an association between longer telomere length and increased NHL risk [four B-cell histologic types combined; odds ratio (OR) = 1.49, 95% CI 1.22-1.82,P-value = 8.5 × 10(-5)]. Subtype-specific analyses indicated that chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL) was the principal NHL subtype contributing to this association (OR = 2.60, 95% CI 1.93-3.51,P-value = 4.0 × 10(-10)). Significant interactions were observed across strata of sex for CLL/SLL and marginal zone lymphoma subtypes as well as age for the follicular lymphoma subtype. Our results indicate that a genetic background that favors longer telomere length may increase NHL risk, particularly risk of CLL/SLL, and are consistent with earlier studies relating longer telomere length with increased NHL risk.

    We performed a pooled analysis of data on atopic disease and risk of non-Hodgkin lymphoma (NHL) from 13 case-control studies, including13,535 NHL cases and 16,388 controls. Self-reported atopic diseases diagnosed two or more years before NHL diagnosis (cases) or interview (controls) were analyzed. Pooled odds ratios (OR) and 95% confidence intervals were computed in two-stage random-effects or joint fixed-effects models, adjusted for age, sex, and study center. When modeled individually, lifetime history of asthma, hay fever, a specific allergy (excluding hay fever, asthma and eczema), and food allergy were associated with a significant reduction in NHL risk, and there was no association for eczema. When each atopic condition was included in the same model, reduced NHL risk was only associated with history of allergy (OR 0.80, 95% CI 0.68–0.94), and reduced B-cell NHL risk was associated with history of hay fever (OR 0.85, 95% CI 0.77–0.95) and allergy (OR 0.84, 95% CI 0.76–0.93). Significant reductions in B-cell NHL risk were also observed in individuals who were likely to be truly or highly atopic - those with hay fever, allergy or asthma and at least one other atopic condition over their lifetime. The inverse associations were consistent for the diffuse large B-cell and follicular subtypes. Eczema was positively associated with lymphomas of the skin; misdiagnosis of lymphoma as eczema is likely, but progression of eczema to cutaneous lymphoma cannot be excluded. This pooled study demonstrates evidence of a modest but consistent reduction in the risk of B-cell NHL associated with atopy. PMID:19654312

    The two genes, named BnNHL18A and BnNHL18B, showing sequence homology with Arabidopsis NDR1/HIN1-like (NHL) genes, were isolated from cDNA library prepared with oilseed rape (Brassica napus) seedlings treated with NaCl. The transcript level of BnNHL18A was increased by sodium chloride, ethephon, hydrogen peroxide, methyl jasmonate, or salicylic acid treatment. The coding regions of BnNHL18A and BnNHL18B contain a sarcolipin (SLN)-like sequence. Analysis of the localization of smGFP fusion proteins showed that BnNHL18A is mainly localized to endoplasmic reticulum (ER). This result suggests that the SLN-like sequence plays a role in retaining proteins in ER membrane in plants. In response to NaCl, hydrogen peroxide, ethephon, and salicylic acid treatments, the protein localization of BnNHL18A was changed. Our findings suggest a common function of BnNHL18A in biotic and abiotic stresses, and demonstrate the presence of the shared mechanism of protein translocalization between the responses to plant pathogen and to osmotic stress.

    Objectives: As an uncommon neoplasm, parotid non-Hodgkin lymphoma (NHL) comprises mucosa-associated lymphoid tissue (MALT) and non-MALT lymphomas. Both types of lymphoma vary in prognosis and treatment. The aim of this study was to explore CT and MRI characteristics of these two types of lymphoma. Methods: 61 cases of parotid NHL, 34 MALT and 27 non-MALT lymphomas with histopathological confirmation were examined with routine CT and MR scans prior to treatment, and retrospectively reviewed. Results: On CT and MRI, 34 MALT lymphomas presented with 11 solid and 23 solid-cystic forms, whereas 27 non-MALT lymphomas presented with 25 solid and 2 solid-cystic forms (p < 0.01). Conclusions: Parotid MALT lymphoma is characterized mainly by the solid-cystic form, whereas non-MALT lymphoma is characterized mainly by the solid form. The differences on CT and MRI can offer helpful information for differentiation of both types of parotid NHL. PMID:23975113

    Background Non-Hodgkin lymphoma (NHL) comprises biologically and clinically heterogeneous subtypes. Previously, study size has limited the ability to compare and contrast the risk factor profiles among these heterogeneous subtypes. Methods We pooled individual-level data from 17 471 NHL cases and 23 096 controls in 20 case–control studies from the International Lymphoma Epidemiology Consortium (InterLymph). We estimated the associations, measured as odds ratios, between each of 11 NHL subtypes and self-reported medical history, family history of hematologic malignancy, lifestyle factors, and occupation. We then assessed the heterogeneity of associations by evaluating the variability (Q value) of the estimated odds ratios for a given exposure among subtypes. Finally, we organized the subtypes into a hierarchical tree to identify groups that had similar risk factor profiles. Statistical significance of tree partitions was estimated by permutation-based P values (P NODE). Results Risks differed statistically significantly among NHL subtypes for medical history factors (autoimmune diseases, hepatitis C virus seropositivity, eczema, and blood transfusion), family history of leukemia and multiple myeloma, alcohol consumption, cigarette smoking, and certain occupations, whereas generally homogeneous risks among subtypes were observed for family history of NHL, recreational sun exposure, hay fever, allergy, and socioeconomic status. Overall, the greatest difference in risk factors occurred between T-cell and B-cell lymphomas (P NODE < 1.0×10−4), with increased risks generally restricted to T-cell lymphomas for eczema, T-cell-activating autoimmune diseases, family history of multiple myeloma, and occupation as a painter. We further observed substantial heterogeneity among B-cell lymphomas (P NODE < 1.0×10−4). Increased risks for B-cell-activating autoimmune disease and hepatitis C virus seropositivity and decreased risks for alcohol consumption and occupation as a

    The etiology of non-Hodgkin lymphoma (NHL) is poorly understood. Obesity is associated with inflammation, a cytokine milieu conducive to lymphocyte proliferation, and has been associated with NHL risk in some epidemiologic studies. To prospectively examine NHL risk in relation to adult and earlier life obesity, we documented 635 incident NHL diagnoses among 46,390 men in the Health Professionals Follow-up Study and 1254 diagnoses among 116,794 women in the Nurses’ Health Study over 22–32 years of follow-up. Using multivariable Cox proportional hazards models we estimated cohort-specific incidence rate ratios (RRs) and 95% confidence intervals (CI) for risk of NHL and major histologic subtypes associated with cumulative average middle and young adult (ages 18–21) body mass index (BMI) and adolescent and childhood somatotype. NHL risk was modestly increased in men (but not women) with a cumulative average middle adult BMI ≥30 kg/m2 (vs. 15–22.9 kg/m2; RR: 1.28; 95% CI: 0.92, 1.77; P-trend=0.05). In meta-analyses across cohorts, higher young adult BMI was associated with increased risk of all NHL (pooled RR per 5 kg/m2: 1.19; 95% CI: 1.05, 1.37), diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL) (all P-trend≤0.02). Adolescent somatotype was also positively associated with all NHL, DLBCL, and FL in pooled analyses (all P-trend ≤0.03) while childhood somatotype was positively associated with NHL overall among women only (P-trend <0.01). These findings in two large prospective cohorts provide novel evidence that larger body size in childhood, adolescence, and young adulthood predicts increased risk of NHL, and particularly of DLBCL and FL.

    Three patients developed non-Hodgkin's lymphoma (NHL) 3 to 6 years after treatment for Hodgkin's disease (HD). In no instance was there evidence of recurrence of HD following the initial chemotherapy or radiotherapy. None of these patients had received both radiation therapy and chemotherapy. All patients responded well to conventional chemotherapy for NHL and are alive at 23 +, 37 +, and 65+ months after that secondary diagnosis. This report, when coupled with at least ten other such reported patients, suggests that NHL may be a relatively uncommon but significant complication of therapy for HD and must be distinguished for recurrence of HD.

    Non-Hodgkin lymphoma (NHL) represents a heterogeneous group of diseases that are known to carry a considerable risk of second primary cancer (SPC). However, little attention has been paid to SPC risk assessment according to NHL subtypes. Data from 10 French population-based cancer registries were used to establish a cohort of 7546 patients with a first diagnosis of NHL (eight subtypes) between 1989 and 2004. Standardized incidence ratios (SIRs) of metachronous SPC were estimated. Among the 7546 patients diagnosed with a NHL, the overall SPC risk was 25% higher than that in the reference population (SIR = 1.25, 95% confidence interval 1.15-1.36). In univariate analysis, the SPC risk differed by lymphoma subtype. Interestingly, multivariate analysis showed that SPC risk did not differ significantly across NHL subtypes after adjustment for the other covariates (p = 0.786). Patients with NHL have an increased risk of SPC that is not influenced by the histological NHL subtype. PMID:25641432

    Context: Non-Hodgkin's lymphoma (NHL) is a group of highly diverse malignancies whose prognosis depends on the histologic type and associated factors like HIV positivity. Aims: The aim of this study was to evaluate eight cases of NHL for their histologic type and HIV positivity, since both are major prognostic factors for NHL. Settings and Design: Eight cases of primary NHL of the oral cavity were evaluated for age, sex, clinical presentation, and the histologic type, along with immunohistochemistry. These cases were also evaluated for HIV positivity. Materials and Methods: NHL cases which were diagnosed through the dental OPD and subsequent biopsy procedure were chosen. The patient data, including age, sex, location, clinical presentation, radiographic presentation, metastasis, and histologic subtype, according to the World Health Organization (WHO) classification were tabulated. Immunohistochemical markers were used to confirm the cell type. CD20 and CD3 were used for B cell and T cell, respectively. Subsequent western blot analysis was carried out for HIV detection. Results: 75% of the NHL was of B-cell type; of this, 83% was found to be diffuse large B-cell lymphoma, which is an aggressive variant. 62.5% of cases were found to be HIV positive. Conclusions: This study emphasizes the need for HIV investigation in NHL cases and the need to determine the histologic type, both of which significantly affect the treatment outcome and prognosis.

We report a case of primary Non-Hodgkin’s Lymphoma (NHL) of left ovary in a 52-year-old female presented with distension of abdomen and lower abdominal back pain. USG and CT-scan imaging suggested provisional diagnosis of ovarian tumour. The diagnosis of malignant lymphoma was made by histopathological examination of the excised tissue along with immunohistochemistry by using LCA, CD20, cytokeratin & CD3. The tumour was classified as diffuse large B cell lymphoma. Rarity of this lesion warrants its mention. PMID:27437236

Here we present a case of advanced primary Pancoast-like left apical lung lymphoma incidentally diagnosed in a 72 year old asymptomatic woman after a routine, prophylactic chest X-ray performed in June 2005. FNB was not diagnostic therefore an open lung biopsy was attempted. Histopathological examination of the excised specimen was consistent with B-cell low-grade marginal zone extranodal NHL (BALTL); CD20+, CD3-. Treatment combined of 9 cycles of chemotherapy followed by radiotherapy of the residual mass allowed to achieve a long-term complete remission. PMID:17973229

    Peripheral T-cell and NK-cell lymphomas are uncommon disorders accounting for 10-15% of all non-Hodgkin lymphomas (NHL). The NHL classification project represents the first attempt to systematically study the distribution of NHL subtypes based on a collaborative international effort and it confirmed the wide geographic variation in the frequency of different subtypes of PTCL. Subsequently, the International T-cell Lymphoma Project (ITLP), the largest collaborative international effort to date, reported prevalence and outcomes of 1314 cases of PTCL from 22 institutions worldwide with central pathology review. The ITLP consortium launched a prospective study, the T-cell project, in September 2006 aimed at collecting an exhaustive clinical and biologic data set on 1000 patients with PTCL for better definition of prognostic factors that would influence outcomes of these patients. This review aims to describe the difference in frequency and outcomes for various subtypes of PTCL based on these studies. PMID:23768638

    Acquired immune deficiency syndrome increases the risk of developing non-Hodgkin's B-cell lymphoma (NHL) (relative risk over 100). NHL tend to be high-grade and to affect the central nervous system and digestive tract. Biliary tract compression is usually due to external compression from enlarged lymph nodes, but is not usually the first manifestation.We describe 2 cases of bile duct obstruction secondary to NHL in patients diagnosed with HIV infection. Histological diagnosis of the lymphoma can be difficult but is necessary so that these patients do not undergo highly aggressive surgical treatment instead of chemotherapy, which currently produces the best results. Therefore, we emphasize the importance of including lymphomas in the differential diagnosis of bile duct obstruction in patients with HIV infection. PMID:14670238

    There is paucity of data on non Hodgkin's lymphoma (NHL) from our population in North-East India. In this retrospective study, patients were consecutively followed-up to see the clinic-pathological pattern of NHL, various responses, and pattern of relapses to first line treatment with chemotherapy. All patients in the present study received standard regimen of cyclophosphamde, doxorubicin, vincristine, prednisolone (CHOP) with or without rituximab (R-CHOP) as per our institutional protocol as first line therapy. Our study has shown that, in our adult population, the majority of NHL cases present with stage II and stage III disease and extra nodal involvement, B-cell lymphomas and diffuse large cell lymphomas being the most common subtypes. International prognostic index was a significant factor for varied responses to treatment. The majority of relapses after complete remission occurred in the first year. PMID:25854376

    Background: Primary CNS lymphoma (PCNSL), a rare form of aggressive extranodal non-Hodgkin's lymphoma (NHL), has increased in incidence during the last three decades and occurs in both immune compromised and immune competent hosts. It has an overall poor prognosis. Objective: This study attempts to further delineate the clinico-pathological, immunohistochemical and radiological profile of PCNSL at Jeddah to King Faisal Hospital and Research Center. Methods: Computerized search through the archives of King Faisal Hospital and Research Centre between July 2000- December 2012 identified 15 patients with pathologically confirmed PCNSL. These were analyzed retrospectively. Their clinico-pathological, immunohistochemical and radiological data were analyzed. Results: Of the 15 PCNSL patients, 8 (53.3%) were females and 7 (46.6%) were males. There was female predilection especially in the age group of 40-59 years. Mean age at diagnosis for all patients was 50.4 years. There was no patient in the pediatric age group. The most common location in the brain was the frontal region in 7 patients (46.6%), 7 (46.6%) had multiple intracranial masses; all 15 (100%) were Non Hodgkin B-cell lymphomas, among which 13 (86.6%) were diffuse large B-cell lymphomas. All 15 (100%) cases showed diffuse and strong positivity for CD 45, and CD 20. Fourteen patients were immune competent while one was immune compromised. Conclusions: PCNSL often occurs in middle-aged and aged patients. There is female predilection especially in the middle age. Frontal region is the most common location with diffuse large B-cell lymphoma being the predominant subtype. PMID:27366250

    2016-07-01

    Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare subtype of Hodgkin lymphoma with distinct clinicopathologic features. It is typified by the presence of lymphocyte predominant (LP) cells, which are CD20(+) but CD15(-) and CD30(-) and are found scattered amongst small B lymphocytes arranged in a nodular pattern. Despite frequent and often late or multiple relapses, the prognosis of NLPHL is very favorable. There is an inherent risk of secondary aggressive non-Hodgkin lymphoma (NHL) and studies support that risk is highest in those with splenic involvement at presentation. Given disease rarity, the optimal management is unclear and opinions differ as to whether treatment paradigms should be similar to or differ from those for classical Hodgkin lymphoma (CHL). This review provides an overview of the existing literature describing pathological subtypes, outcome and treatment approaches for NLPHL. PMID:27496311

    Primary extranodal Non-Hodgkin lymphoma (NHL) is a non epithelial tumours that accounts for 40% of cases of NHL. Spread of nodal lymphomas to the gastrointestinal tract (GIT) is the most common location. Within the GIT is the stomach the most affected organ (60%). We report the case of 52-year- old man , mining company worker for over 10 years, which is derived to the Service of Gastroenterology with history of epigastric pain, nausea, vomiting and weight loss. Upper gastrointestinal endoscopic examination revealed an ulcerated lesion on greater curve of stomach and histopathological examination and subsequent immunohistochemical analysis showed diffuse large B cell gastric NHL. Also, the patient had multiple organ involvement in relation to chronic exposure to heavy metals, which was found in the mineralograma, with the highest concentration of uranium, thallium, arsenic, lead and mercury. The literature has described the association of chronic occupational exposure to uranium and arsenic with NHL presenting gastrointestinal involvement. Therefore, gastric commitment can not be considered as an isolated injury, but rather part of systemic involvement associated with elevated concentrations of metals. Mining is a key driver of income for Peru; however, there are no reports to date of the association of gastrointestinal NHL commitment regarding occupational exposure to heavy metals. PMID:23307094

    The World Health Organization classification of non-Hodgkin lymphoma (NHL) was introduced in 2001. However, its incorporation into clinical practice is not well-described. We studied the distribution of NHL subtypes in adults diagnosed from 1998 to 2011, evaluated time trends, geo-demographic correlates, and changes in 5-year overall survival (OS). We obtained data prospectively collected by the National Cancer Data Base, which covers 70% of US cancer cases. There were 596,476 patients diagnosed with NHL. The major subtypes were diffuse large B-cell (32.5%), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL; 18.6%), follicular (17.1%), marginal zone (8.3%), mantle cell (4.1%), peripheral T-cell not-otherwise-specified (1.7%), Burkitt (1.6%), hairy cell (1.1%), lymphoplasmacytic (1.1%), and NHL not-otherwise-specified (10.8%). Over the study period, the proportion of NHL not-otherwise-specified declined by half, while marginal zone lymphoma doubled. The distribution of major and rare NHL subtypes varied according to demographics but less so geographically or by type of treatment facility. We noted several novel findings among Hispanics (lower proportion of CLL/SLL, but higher Burkitt lymphoma and nasal NK/T-cell lymphoma), Asians (higher enteropathy-associated T-cell and angioimmunoblastic T-cell lymphomas), Blacks (higher hepatosplenic T-cell lymphoma), and Native Americans (similar proportions of CLL/SLL and nasal NK/T-cell lymphoma as Asians). With the exception of peripheral T-cell not-otherwise-specified and hairy cell leukemia, 5-year OS has improved for all the major NHL subtypes. PMID:26096944

    The methylenetetrahydrofolate reductase (MTHFR) gene codes for the MTHFR enzyme which plays a key role in the pathway of folate and methionine metabolism. Polymorphisms of genes in this pathway affect its regulation and have been linked to lymphoma. In this study we examined whether we could detect an association between two common non-synonymous MTHFR polymorphisms, 677C > T (rs1801133) and 1298A > C (rs1801131), and susceptibility to non-Hodgkin lymphoma (NHL) in an Australian case–control cohort. We found no significant differences between genotype or allele frequencies for either polymorphisms between lymphoma cases and controls. We also explored whether epigenetic modification of MTHFR, specifically DNA methylation of a CpG island in the MTHFR promoter region, is associated with NHL using blood samples from patients. No difference in methylation levels was detected between the case and control samples suggesting that although hypermethylation of MTHFR has been reported in tumour tissues, particularly in the diffuse large B-cell lymphoma subtype of NHL, methylation of this MTHFR promoter CpG island is not a suitable epigenetic biomarker for NHL diagnosis or prognosis in peripheral blood samples. Further studies into epigenetic variants could focus on genes that are robustly associated with NHL susceptibility. PMID:26629414

    Follicular lymphoma and diffuse large B cell lymphomas comprise the main entities of adult B cell malignancies. Although multiple disease driving gene aberrations have been identified by gene expression and genomic studies, only a few studies focused at the protein level. We applied 2 dimensional gel electrophoresis to compare seven GC B cell non Hodgkin lymphoma (NHL) cell lines with a lymphoblastoid cell line (LCL). An average of 130 spots were at least two folds different in intensity between NHL cell lines and the LCL. We selected approximately 38 protein spots per NHL cell line and linked them to 145 unique spots based on the location in the gel. 34 spots that were found altered in at least three NHL cell lines when compared to LCL, were submitted for LC-MS/MS. This resulted in 28 unique proteins, a substantial proportion of these proteins were involved in cell motility and cell metabolism. Loss of expression of B2M, and gain of expression of PRDX1 and PPIA was confirmed in the cell lines and primary lymphoma tissue. Moreover, inhibition of PPIA with cyclosporine A blocked cell growth of the cell lines, the effect size was associated with the PPIA expression levels. In conclusion, we identified multiple differentially expressed proteins by 2-D proteomics, and showed that some of these proteins might play a role in the pathogenesis of NHL. PMID:26752561

    Non-Hodgkin lymphoma (NHL) of the breast is a rare disease. Herein, we report a rare case of secondary involvement of the breast by NHL in a male patient and the ultrasound imaging findings. A 70-year-old man noticed an induration of the subareolar region of the right breast. He had been diagnosed as having mantle cell lymphoma 5 years before and treated with several series of chemoradiotherapy. On supine examination, palpation revealed bilateral breast enlargement, but detection of a lump was difficult. Ultrasonography showed a hypoechoic non-mass image-forming lesion in the subareolar region of the right breast. The final pathological diagnosis was recurrence of mantle cell lymphoma in the right breast. The diagnosis of malignant lymphoma of the breast by imaging modalities is difficult because there are no specific features. Breast lymphoma should be included with gynecomastia and breast cancer in the differential diagnosis of male patients with breast enlargement. PMID:22396322

    Follicular lymphoma (FL) is a common form of non-Hodgkin's lymphoma (NHL) with the ability to transform into a more aggressive disease, frequently to B cell-lymphoblastic lymphoma. Diffuse large B-cell lymphoma (DLBCL) is a subtype of NHL, which is characterized by diffuse proliferation of large neoplastic B-lymphocytes. It accounts for 30% of all NHL and its occurrence in the mandible is very rare. It is often seen in young adults, but in the present case, a 50-year-old male patient presented with painless swelling in left lower jaw since 25 days following extraction of left lower molar teeth. There was a history of fever and submandibular lymph nodes were enlarged. On incisional biopsy, features of NHL-like lesion were observed and confirmed by immunohistochemistry using CD20, bcl-2, CD10, CD3, CD5, Ki67 markers to be FL (3A) lymphoma transforming into DLBCL. This is a very uncommon presentation. PMID:26980969

    Between 1973 and 1989, 16 children with non-Hodgkins lymphoma (NHL) with a mediastinal mass (MM) were treated at our institution with multi-agent chemotherapy and radiotherapy. They also received central nervous system (CNS) prophylaxis including intrathecal methotrexate administration (14 cases) and cranial irradiation (7 cases). Twelve were boys and 4 girls. Median age was 11 +/- 3. One patient died of air way obstruction one day after admission. Fourteen of 15 patients entered into complete remission (CR) and one patient partial remission. Five remains in CR 7 to 175 months after diagnosis (median 76 months). Nine patients relapsed in the bone marrow (3 cases), CNS (3), testicles (1), neck lymph node (1) and bones plus kidneys (1). Of these, 7 patients died within 13 months after initial relapse. The disease free survival (DFS) and overall survival of all patients were 27% and 33%, respectively. Analysis of the prognostic factors among patients with MM+ -NHL revealed that the serum LDH level below 1,000IU/l was a good prognostic sign. Other factors such as age, stage, initial WBC count, size of MM and response of the MM to the initial treatment did not correlate with DFS. Because of its rarity and the poor treatment result, we need more aggressive treatment program by a multiinstitutional study for MM+ -NHL. PMID:2287064

    Systemic non-Hodgkin lymphoma (S-NHL) is a common malignancy during HIV infection, and it is hypothesized that infectious agents may be involved in the etiology. Epstein-Barr virus DNA is found in <40% of patients with AIDS-related S-NHL, suggesting that other oncogenic viruses, such as polyomaviruses, may play a role in pathogenesis. We analyzed AIDS-related S-NHL samples, NHL samples from HIV-negative patients, peripheral blood leukocytes from HIV-infected and -uninfected patients without NHL, and lymph nodes without tumors from HIV-infected patients. Specimens were examined by polymerase chain reaction analysis with use of primers specific for an N-terminal region of the oncoprotein large tumor antigen ( T-ag ) gene conserved among all three polyomaviruses (simian virus 40 [SV40], JC virus, and BK virus). Polyomavirus T-ag DNA sequences, proven to be SV40-specific, were detected more frequently in AIDS-related S-NHL samples (6 of 26) than in peripheral blood leukocytes from HIV-infected patients (6 of 26 vs. 0 of 69; p =.0001), NHL samples from HIV-negative patients (6 of 26 vs. 0 of 10; p =.09), or lymph nodes (6 of 26 vs. 0 of 7; p =.16). Sequences of C-terminal T-ag DNA from SV40 were amplified from two AIDS-related S-NHL samples. Epstein-Barr virus DNA sequences were detected in 38% (10 of 26) AIDS-related S-NHL samples, 50% (5 of 10) HIV-negative S-NHL samples, and 57% (4 of 7) lymph nodes. None of the S-NHL samples were positive for both Epstein-Barr virus DNA and SV40 DNA. Further studies of the possible role of SV40 in the pathogenesis of S-NHL are warranted.

    A case report of boutonneuse fever with pulmonary complications in a patient with non-Hodgkin's lymphoma (NHL) is described. The patient was hospitalized for persistent hypertermia and marked dyspnea, with radiographic findings of bilateral involvement of the lungs. The confirmation of the diagnosis was obtained by means of serum analyses (Weil-Felix serodiagnosis and IFA); the patient responded to doxycycline with progressive improvement of her general health condition. In this case the occurrence of a NHL could justify the lower reactivity and the facilitated diffusion of rickettsiosis in the patient. PMID:9250284

    Children with human immunodeficiency virus (HIV) have an increased risk of developing Kaposi Sarcoma (KS) and non-Hodgkin lymphoma (NHL) compared to HIV-negative children. We compiled currently published epidemiologic data on KS and NHL among children in sub-Saharan Africa (SSA). Among countries with available data, the median incidence of KS was 2.05/100,000 in the general pediatric population and 67.35/100,000 among HIV-infected children. The median incidence of NHL was 1.98/100,000 among the general pediatric population, while data on NHL incidence among HIV-infected children were lacking. Larger regional studies are needed to better address the dearth of epidemiologic information on pediatric KS and NHL in SSA. PMID:27082516

    Mantle cell lymphoma (MCL) is an infrequent subtype of non-Hodgkin’s lymphoma (NHL) and represents between 4–8% of adult lymphomas. Recently an increase in its incidence to 1–2 cases/100,000 inhabitants/year has been observed. The first line of treatment is based on chemoimmunotherapy and depends on age and the initial stage at diagnosis. There are no second line or successive treatments. There are currently several drugs available that provide acceptable results. PMID:27110283

    Nutritional status is known to alter immune function, a suspected risk factor for non-Hodgkin lymphoma (NHL). To investigate whether long-term over, or under, nutrition is associated with NHL self-reported anthropometric data on weight and height from over 10000 cases of NHL and 16000 controls were pooled across 18 case-control studies identified through the International Lymphoma Epidemiology Consortium. Study-specific odds ratios (OR) were estimated using logistic regression and combined using a random-effects model. Severe obesity, defined as BMI of 40 kg m−2 or more, was not associated with NHL overall (pooled OR=1.00, 95% confidence interval (CI) 0.70–1.41) or the majority of NHL subtypes. An excess was however observed for diffuse large B-cell lymphoma (pooled OR=1.80, 95% CI 1.24–2.62), although not all study-specific ORs were raised. Among the overweight (BMI 25–29.9 kg m−2) and obese (BMI 30–39.9 kg m−2), associations were elevated in some studies and decreased in others, while no association was observed among the underweight (BMI<18.5 kg m−2). There was little suggestion of increasing ORs for NHL or its subtypes with every 5 kg m−2 rise in BMI above 18.5 kg m−2. BMI components height and weight were also examined, and the tallest men, but not women, were at marginally increased risk (pooled OR=1.19, 95% CI 1.06–1.34). In summary, whilst we conclude that there is no evidence to support the hypothesis that obesity is a determinant of all types of NHL combined, the association between severe obesity and diffuse large B-cell lymphoma may warrant further investigation.

    Exposure to traffic noise may result in stress and sleep disturbances, which have been associated with impairment of the immune system. People with weakened immune systems are known to have a higher risk for non-Hodgkin lymphoma (NHL). We aimed to determine whether traffic noise was associated with risk for NHL in a nationwide case-control study. We identified 2753 cases aged 30-84 years with a primary diagnosis of NHL in Denmark between 1992 and 2010. For each case we selected two random population controls, matched on sex and year of birth. Road traffic and railway noise were calculated, and airport noise was estimated for all present and historical residential addresses of cases and controls from 1987 to 2010. Associations between traffic noise and risk for NHL were estimated using conditional logistic regression, adjusted for disposable income, education, cohabiting status and comorbidity. We found that a 5-year time-weighted mean of road traffic noise above 65 dB was associated with an 18% higher risk for NHL (95% confidence interval (CI) 1.01-1.37) when compared to road traffic noise below 55 dB, whereas for exposure between 55 and 65 dB no association was found (odds ratio: 0.98; 95% CI: 0.88-1.08). In analyzes of NHL subtypes, we found no association between road traffic noise and risk for T-cell lymphoma, whereas increased risks for B-cell lymphoma and unspecified lymphomas were observed at exposures above 65 dB. In conclusion, our nationwide study may indicate that high exposure to traffic noise is associated with higher NHL risk. PMID:26113038

    The purpose of this article is to review the literature for clinical presentation, treatment, outcome and complications of using radiotherapy for the treatment of orbital lymphoma. For this, MEDLINE, EMBASE, and the Cochrane Library were searched through January 2007 for published data on primary non-Hodgkin's lymphoma (NHL) of the orbit. The search was conducted in all document types, using the following terms “Non-Hodgkin's lymphoma, MALT (mucosa associated lymphoid tissue) and orbit”. Data extracted were based on age, sex, therapeutic methods and outcome of treatment. When full articles were not available, abstracts were used as a source of information. Only those articles whose abstracts or full text were available in English were included in table. The review of reports of NHL of the orbit, in general, served as a source of information about its clinical behavior, treatment and overall prognosis. Fifty-six publications were identified, including six in languages other than English. There was no randomized trial. All the studies were retrospective. The studies were heterogeneous in patient number (3 to 112), histology, disease stage (IE to IV), radiotherapy doses used (4 to 53.8Gy), local control rates (65 to 100%), distant relapse rates (0 to 67%, from low grade to high grade) and five-year survival rates (33 to 100%). Three of the studies with a good number of patients also demonstrated clinical benefit with radiotherapy in terms of superior efficacy or less toxicity. Available data support the acceptance of radiotherapy as a standard therapeutic option in patients with low to intermediate grade orbital lymphoma. Toxicity of radiotherapy is mild if delivered precisely. PMID:19237780

    Background Various infectious agents like Ebstein Barr Virus (EBV), HTLV-1 and Helicobacter pylori have known as etiologic factors in different sub-types of lymphoma. Although Hepatitis C virus (HCV) has not only been important for its hepatotropism and hepatitis development, but also in recent years its association with some forms of non- Hodgkin’s lymphoma (NHL), especially B cell NHL, has reported.In some countries, the rate of B cell NHL development in HCV infected patients was four times more than general population, and then association between HCV infection and B-NHL has proposed in many studies. Methods To assess this relationship in our geographic region, in a descriptive study; we have evaluated patients with B-NHL in an oncology center in northeast of Iran for HCV infection. Results Out of 128 B-NHL patients, HCV Antibody test (with third generation ELISA method) was positive in only one patient, which confirmed with Nested PCR technique. Then the frequency of HCV infection in our patients was 0.7%. Conclusion Respecting to the incidence of HCV infection in general population in Iran, which is between 0.5-1%, we couldn’t show higher prevalence of HCV infection in NHL patients than general population, and hence couldn’t confirm relation between HCV infection and B-NHL in our region.

    The risk of second malignancies following non-Hodgkin's lymphoma (NHL) was estimated in 29,153 patients diagnosed with NHL between 1973 and 1987 in one of nine areas participating in the National Cancer Institute's Surveillance, Epidemiology, and End Results Program. Compared with the general population, NHL patients were at a significantly increased risk of developing second cancers (observed/expected (O/E) = 1.18; O = 1231). The O/E ratio increased significantly with time to reach 1.77 in 10-year survivors. Significant excesses were noted for acute nonlymphocytic leukemia (O/E = 2.88), cancers of the bladder (O/E = 1.30), kidney (O/E = 1.47), and lung (O/E = 1.57), malignant melanoma (O/E = 2.44), and Hodgkin's disease (O/E = 4.16). Chemotherapy appeared related to subsequent acute nonlymphocytic leukemia (ANLL) and bladder cancer. Radiation therapy was associated with ANLL and possibly cancers of the lung, bladder, and bone. Malignant melanoma was not clearly related to initial NHL treatment.

    Little is known about the risk of non-Hodgkin lymphoma (NHL) in nonsmokers who are exposed to environmental tobacco smoke (ETS). Previous research on NHL and ETS has not included men or examined doses of ETS exposure during childhood. The Cancer Prevention Study II Nutrition Cohort collected information on smoking habits and exposure to ETS during childhood and adulthood. Among 61,326 never-smoking men and women, 884 incident cases of NHL were identified between 1992 and 2009. Multivariable-adjusted relative risks and 95% confidence intervals were calculated using Cox proportional hazards regression to identify associations between ETS and NHL risk. Compared with no exposure to ETS as a child or an adult, childhood and/or adult ETS exposure was not associated with NHL overall. There was a positive association between the number of smokers in the house as a child (P for trend = 0.05) and exposure to 6 or more hours per week of ETS as an adult (relative risk = 2.37, 95% confidence interval: 1.12, 5.04) with follicular lymphoma risk. Adult ETS exposure was associated with a lower risk of diffuse large B-cell lymphoma (relative risk = 0.68, 95% confidence interval: 0.48, 0.97). This study suggests that adult and childhood ETS exposure may affect the risk of NHL, and that the associations differ by histological subtype. PMID:24569639

    The spectrum of non-Hodgkin's lymphomas (NHL) that occurs in children differs markedly from that in adults. This is probably a consequence of differences in the proportions of precursor and mature lymphoid cells in the immune systems of children and adults, and the greater emphasis on the development of an immunologic repertoire in the child. Childhood NHL can be classified into three main types based on histology, all of them diffuse: lymphoblastic, small noncleaved cell, and large cell. The majority of lymphoblastic lymphomas are of immature T cell (thymocyte) origin, although a few have a B cell precursor phenotype. All express the enzyme terminal transferase. Small noncleaved lymphomas express B cell characteristics, as do the majority do the majority of large cell lymphomas, although a small proportion of the latter express T cell characteristics. Very few are of true histiocytic origin. Little is known of the epidemiology of lymphoblastic and large cell lymphomas. However, using histology as a diagnostic criterion, both occur throughout the world and occur primarily, as do all childhood NHL, in the first two decades of life. There appear to be at least two types of small noncleaved cell lymphomas, both of which are associated with specific chromosomal translocations. An endemic form occurs at high frequency in equatorial Africa, and a sporadic form occurs at low frequency throughout the world. The endemic tumor is associated with the Epstein-Barr virus, it has a high incidence of jaw tumors, and has a breakpoint on chromosome 8 that is usually some distance upstream of the c-myc oncogene. The sporadic tumor is only occasionally associated with EBV, it often involves the bone marrow, particularly at relapse, and has a breakpoint on chromosome 8 that is usually very close to or within the c-myc oncogene. Childhood NHL is rarely truly localized, and treatment regimens are always based on chemotherapy. There is no evidence that radiation is beneficial when modern

    Lymphomas are subdivided into HL and NHL and are more specifically classified into subtypes of HL or NHL according to the WHO classification. HLs involve the lymph nodes predominantly and only approximately 5% arise in extranodal sites, whereas 30% of NHLs present in extranodal sites. Imaging studies, including CT and MR imaging, cannot distinguish [figure: see text] HL from NHL, and cannot differentiate their various subtypes, necessitating a pathologic diagnosis. Clinical parameters, however, can be helpful in differentiating the two broad categories of lymphomas, and subtypes of lymphomas have predilections for different sites within the head and neck. HL is most commonly located in the lymph nodes of the neck and mediastinum. Marginal-zone lymphoma has an affinity for the ocular adnexa, salivary glands, larynx, and the thyroid gland. Diffuse large B-cell lymphoma is commonly encountered in the paranasal sinuses, mandible, maxilla, and Waldeyer ring. Burkitt lymphoma occurs more frequently in children and young adults and frequently affects the maxilla and mandible, with a greater distribution of involvement at a lower frequency. On imaging studies, the lymph nodes of HL and NHL are homogeneous and variable in size, with an average diameter from 2 to 10 cm. They may enhance slightly to moderately, display necrosis before and after treatment, and display calcification post-treatment. NHL in extranodal sites in the head and neck (nasopharynx, Waldeyer ring, oral cavity, and larynx) manifests frequently as a submucosal mass accompanied [figure: see text] by polypoid, bulky masses with a smooth mucosal surface. Clinically aggressive lymphomas, such as Burkitt lymphoma, diffuse large B-cell lymphoma, and NK-/T-cell lymphomas are characterized by destruction of the maxilla, mandible, and bones around the paranasal sinuses, which is indistinguishable from bony destruction in other malignant tumors, such as SCC. Contrast CT is indicated for evaluation of cervical lymph

    HIV-associated lymphoproliferative disorders represent a heterogeneous group of diseases, arising in the presence of HIV-associated immunodeficiency. The overall prevalence of HIV-associated lymphoma is significantly higher compared to that of the general population and it continues to be relevant even after the wide availability of highly active antiretroviral therapy (HAART) (1). Moreover, they still represent one of the most frequent cause of death in HIV-infected patients. Epstein–Barr virus (EBV), a γ-Herpesviruses, is involved in human lymphomagenesis, particularly in HIV immunocompromised patients. It has been largely implicated in the development of B-cell lymphoproliferative disorders as Burkitt lymphoma (BL), Hodgkin disease (HD), systemic non Hodgkin lymphoma (NHL), primary central nervous system lymphoma (PCNSL), nasopharyngeal carcinoma (NC). Virus-associated lymphomas are becoming of significant concern for the mortality of long-lived HIV immunocompromised patients, and therefore, research of advanced strategies for AIDS-related lymphomas is an important field in cancer chemotherapy. Detailed understanding of the EBV lifecycle and related cancers at the molecular level is required for novel strategies of molecular-targeted cancer chemotherapy The linkage of HIV-related lymphoma with EBV infection of the tumor clone has several pathogenetic, prognostic and possibly therapeutic implications which are reviewed herein.

    Idelalisib is a first-in-class, oral, selective phosphatidylinositol 3-kinase δ inhibitor that offers a chemotherapy-free option for patients with relapsed or refractory (R/R) indolent non-Hodgkin lymphoma (iNHL). Clinical trials in iNHL have evaluated idelalisib as monotherapy and as combination therapy with rituximab, bendamustine, and rituximab + bendamustine. When administered to heavily pretreated patients with R/R iNHL, idelalisib monotherapy or combination therapy showed durable antitumor activity accompanied by sustained or improved quality-of-life outcomes. Idelalisib has an acceptable safety profile; however, serious or fatal diarrhea/colitis, hepatoxicity, pneumonitis, and intestinal perforation have occurred in treated patients. Selective inhibition of phosphatidylinositol 3-kinase δ with idelalisib is a valuable addition to available treatment options for patients with iNHL, many of whom do not respond to or cannot tolerate chemoimmunotherapy. Two Phase III, randomized, placebo-controlled trials of idelalisib as combination therapy with rituximab or bendamustine + rituximab and a Phase I trial of idelalisib in combination with the Bruton’s tyrosine kinase inhibitor ONO/GS-4059 in R/R B-cell malignancies are currently ongoing. A Phase III monotherapy trial in previously treated follicular lymphoma or small lymphocytic lymphoma is planned. The development of other kinase inhibitors for the treatment of iNHL raises the potential for new treatment combinations. Additional research is needed to determine optimal therapy (monotherapy vs combination regimens), treatment sequencing, and long-term management. PMID:27274288

    Breast lymphoma is a rare condition, both as a primary and a metastatic manifestation. The primary form has an incidence ranging from 0.04% to 0.5% of all breast neoplasms, whereas the metastatic form has an incidence of 0.07%. We hereby report a clinical case of a patient who presented with cutaneous non-Hodgkin lymphoma (NHL) in the left scapulohumeral region treated with surgery followed by radiotherapy (40 Gy total). Three years following radiotherapy, the patient was diagnosed with a left breast infiltrating ductal carcinoma, treated with conservative surgery and adjuvant therapy. The following year, i.e. four years after the initial diagnosis of NHL, two lymphoproliferative relapses occurred: in the left cutaneous scapulohumeral region at the original site of disease, and in the right breast. The aim of this paper is to highlight an uncommon oncologic disorder such as breast lymphoma, highlighting its clinical and radiological manifestations. Some studies reported a possible aetiological role of radiotherapy in the development of breast cancer following treatment of NHL, and in the development of breast cancer following treatment of Hodgkin lymphoma, which could potentially explain our findings.

    Iatrogenic immunosuppression is a strong risk factor for non-Hodgkin lymphoma (NHL) but the dose-related association between individual immunosuppressive agents and NHL risk is unknown. We conducted a population-based cohort study of 4131 adult Australian liver, heart and lung transplant recipients (1984-2006). We ascertained NHL incidence by probabilistic record linkage between transplant registries and the Australian Cancer Database, and abstracted risk factor data at transplantation and at regular intervals thereafter from medical records. We estimated adjusted hazard ratios (HR) for early (<1 year after transplantation; n = 29) and late (≥1 year; n = 61) NHL using the Fine and Gray proportional subdistribution hazards model that accounted for death as a competing risk. After adjustment for immunosuppression, the risk of both early and late NHL did not significantly differ by organ type. In final models, higher mean daily doses of azathioprine were associated with increased risk of both early [HR 2·20, 95% confidence interval (CI): 1·21-4·01] and late NHL (HR 1·78, 95% CI: 1·12-2·84). There was no association between any other maintenance immunosuppressive agent and NHL risk. This study provides evidence that differences in immunosuppression may explain variation in NHL incidence by organ type, and high doses of azathioprine may independently predict NHL risk.

    Phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) signaling pathway is extensively explored in cancers. It functions as an important regulator of cell growth, survival and metabolism. Activation of this pathway also predicts poor prognosis in numerous human malignancies. Drugs targeting this signaling pathway have been developed and have shown preliminary clinical activity. Accumulating evidence has highlighted the important role of PI3K in non-Hodgkin lymphoma (NHL), especially in the disease initiation and progression. Therapeutic functions of PI3K inhibitors in NHL have been demonstrated both in vivo and in vitro. This review will summarize recent advances in the activation of PI3K signaling in different types of NHL and the applications of PI3K inhibitors in NHL treatment. PMID:24252186

    Malignant non Hodgkin lymphomas (NHL) are fairly frequent, but involvement of the bony cavities of the face is less common than invasion of the cervical lymph nodes and the lymphoid components of Waldeyer's ring. In connection with a series of 17 personal observations, the authors discuss the main features of NHL and review the diagnostic problems and therapeutic alternatives. Two histologic-clinical entities can be defined: orbital NHL: generally stage I, with a low or intermediate histoprognostic grade and a good prognosis; naso-sinusal NHL: often locally advanced, these lesions are often associated with other visceral disease sites; the prognosis for these intermediate or high histo-prognostic grade lesions is much more somber.

    Early therapy response assessment with metabolic imaging is potentially useful to determine prognosis in aggressive lymphoma and, thus, can guide first-line therapy. Forty-eight patients with aggressive lymphoma [24 Hodgkin's disease (HD); 24 non-Hodgkin's lymphoma (NHL)] underwent fluoro-deoxyglucose positron emission tomography (FDG-PET) before chemotherapy (PET1) and at mid-treatment (PET2). Therapeutic response was evaluated using conventional methods at mid-treatment. PET2 results were related to event-free survival (EFS) and overall survival (OS) using Kaplan-Meier analyses. PET1 was positive in all patients. PET2 was negative in 38 patients (18 NHL-20 HD) and positive in 10 (6 NHL-4 HD). Of the PET-negative patients, 61 and 65% achieved complete remission, and only 50 and 25% of PET-positive patients, respectively, for NHL and HD, achieved complete remission. Significant associations were found between PET2 and EFS (p = 0.0006) and OS (p = 0.04) for NHL, and EFS (p < 0.0001) for HD (but not for OS, because no HD patient died). FDG-PET at mid-treatment can predict the outcome of patients with aggressive lymphoma and should be a useful tool to modify an ineffective therapy. PMID:16871391

    This study aims to examine the levels of circulating endothelial progenitor cells (cEPCs) in the peripheral blood of patients with non-Hodgkin lymphoma (NHL) and their correlation with the tumor stage. Forty-one patients with biopsy-proven NHL and 16 healthy individuals were recruited. Peripheral blood mononuclear cells (PBMCs) were isolated by density gradient centrifugation, and cEPCs were characterized by triple staining using antibodies against CD133, CD34 and vascular endothelial growth factor receptor-2 (VEGFR-2, CD309) and quantified by flow cytometry. In NHL patients, the number of cEPCs was significantly greater than in control group (P=0.000). The cEPCs counts in patients with NHL of stage III-IV were significantly greater than in stage I-II (P=0.010). FACS analysis revealed that the number of cEPCs in NHL patients had no correlation with the gender (P=0.401) or the pathological category (P=0.852). It was suggested that the over-expression of cEPCs in NHL patients may serve as a novel biomarker for disease progression in NHL. PMID:23592145

    Non-Hodgkin lymphoma (NHL) is the most common hematologic malignancy worldwide. Interleukin-2 (IL-2) plays a key role in the proliferation of T cells and natural killer cells. It has been reported that polymorphisms in the IL-2 gene are associated with various cancers. The aim of this study was to examine the effect of polymorphisms in the IL-2 gene on the development of NHL in the Chinese population. IL-2-330T/G and +114T/G polymorphisms were detected by polymerase chain reaction–restriction fragment length polymorphism in 438 NHL cases and 482 age-matched healthy controls. Data were analyzed using the Chi-square test. Results showed that individuals with −330TG genotype or −330GG genotype had significantly increased susceptibility to NHL (Odds ratio [OR]=1.40, 95% confidence interval [CI]: 1.05–1.85, p=0.020 and OR=2.04, 95%CI: 1.28–3.24, p=0.002). Meanwhile, the +114T/G polymorphism did not show any correlation with NHL. When analyzing the haplotypes of these two polymorphisms, the prevalence of −330G/+114T haplotype was significantly higher in NHL cases than in controls (OR=1.45, 95%CI: 1.12–1.88, p=0.005). These data indicate that IL-2 gene polymorphisms may be new risk factors for NHL. PMID:22472080

    The purpose of this paper was to define the histologic distribution, clinical features, and treatment response of childhood non-Hodgkin lymphoma (NHL) in northeastern Brazil. We reviewed medical records and histopathologic studies of 98 children treated for NHL from 1980 to 1987 at a major pediatric cancer center in Recife, Brazil. Treatment outcome was evaluated in relation to tumor burden (stage and serum LDH) and type of therapy (LSA2L2 vs other multiagent chemotherapy). There was a striking predominance of the small noncleaved cell (Burkitt) subtype, which occurred in 92 of the 98 children and adolescents diagnosed with NHL. Subsequent analyses focused on these patients. The majority (n = 84) had advanced (stage III/IV) disease at diagnosis. The abdomen was the most common site of disease (84 cases); jaw involvement was rare (three cases). Five-year event-free survival (excluding treatment refusals) was significantly better for patients with limited vs advanced stage disease (75 +/- 14% vs 42 +/- 6%; P < 0.04). Elevated serum LDH (>500 U/l) was associated with a poorer outcome (P = 0.008). The type of chemotherapy did not affect EFS (P = 0.95). Only 39% of patients are long-term survivors, reflecting the high rate of septic deaths (25% of patients) and parental refusal/abandonment of therapy (10%). Epstein-Barr virus (EBV) was detected in tumor cells from eight of the 11 cases studied. In clinical presentation, these cases resemble sporadic Burkitt lymphoma, yet in their apparent responsiveness to LSA2L2 therapy and association with EBV, they do not. Childhood NHL in northeastern Brazil is predominantly of the Burkitt subtype, and is associated with clinical features that appear to distinguish it from the endemic and sporadic forms of this tumor. These cases may represent a third or intermediate subtype of Burkitt lymphoma. PMID:9180301

    Non-Hodgkin's lymphoma constitutes a group of disorders originating from the malignant transformation of lymphocytes and involving either the lymph nodes or extranodal sites. NHL commonly presents in the sixth to seventh decade of life with a male preponderance (50-75 %). Recent studies have shown importance of serum LDH in prognosis of NHL. Authors report a case of a 63 year old male presenting with complaints of fever and backache for past 4 months. General and systemic examination revealed bilateral axillary lymphadenopathy and splenomegaly respectively. Serum LDH level was highly elevated (3441 U/l). Excisional axillary and bone marrow biopsy were done before oncology referral. Complete workup revealed diffuse Non-Hodgkin's lymphoma with bone marrow infiltration. Patient died because of acute renal failure due to NHL and DM 2 (Type 2 diabetes mellitus). PMID:27069334

    Joints and larynx are uncommonly involved by non-Hodgkin's lymphoma (NHL). Synovial involvement has been reported in only 7 cases, mainly located in the knees. When this is the first location of NHL it is usually misdiagnosed. The treatment of choice is local radiotherapy followed by systemic chemotherapy. Laryngeal lymphoma can be either primary or forming part of multifocal disease. The prognosis of the primary form is usually good only with radiotherapy, whereas the prognosis of the laryngeal location of advanced disease is rather poor. The symptoms include dysphonia and slowly progressive dyspnea. A case of NHL is presented who showed initial arthritis of the knee, later evolving into severe laryngeal obstruction, an association not previously reported. PMID:1585240

    Paediatric B-cell non-Hodgkin lymphoma (B-NHL) compromises a heterogeneous group of histological entities of which Burkitt lymphoma is the most common. In resource-rich countries, the expected cure rate is in excess of 85% with application of risk-adapted short intensive chemotherapy. In recent years, large paediatric cooperative group trials have sought to improve upon outcomes by decreasing the intensity of cytotoxic treatment as well as introducing targeted therapies, such as rituximab. These efforts have resulted in excellent outcomes, however there remains a group of high-risk patients for whom novel treatment approaches are needed. In this review, we will summarize the recent paediatric clinical trials in B-NHL as well as compare treatment approaches across the major cooperative groups. We will also highlight our current understanding of the molecular biology of paediatric B-NHL with a focus on how this may help guide future rational targeted therapy. PMID:26996160

    Infections and malignancies are common causes of pleural effusion. Among infectious causes, hyperinfection syndrome of Strongyloides stercoralis may occur in immunosuppressive patient. A 62-year-old man, known case of Non-Hodgkin lymphoma (NHL) was presented with recurrent NHL stage IV and had undergone salvage chemotherapy. Patient subsequently developed pneumonia with bilateral pleural effusion and ascites. We reported rhabditiform larvae of S. stercoralis in pleural fluid of both lungs without infiltration by lymphoma cells. Stool for microscopic examination also revealed rhabditiform larvae of S. stercoralis. This patient was a known case of NHL receiving chemotherapy resulting in immunosuppression state. Although S. stercoralis infection is not very common compared to other parasitic infections, it is common in immunosuppressive patients and may present with hyperinfection. Therefore, awareness of this parasite should be kept in mind in immunosuppressive patients. PMID:21602770

    PURPOSE HIV-infected persons have an elevated risk of developing non-Hodgkin's lymphoma (NHL); this risk remains increased in the era of effective HIV therapy. We evaluated serum immunoglobulin (Ig) proteins as predictors of NHL risk among HIV-infected individuals. PATIENTS AND METHODS By using three cohorts of HIV-infected persons (from 1982 to 2005), we identified 66 individuals who developed NHL and 225 matched (by cohort, sex, ethnicity, age, and CD4 count), HIV-infected, lymphoma-free controls who had available stored prediagnostic blood samples. Serum/plasma samples obtained 0 to 2 years and 2 to 5 years before diagnosis/selection were assayed for IgG, IgM, and IgA levels; monoclonal (M) Igs; and kappa and lambda free light chain (FLC) levels. Patients and matched controls were compared by using conditional logistic regression. Results The kappa and lambda FLCs were both significantly higher in patients (eg, in 2- to 5-year window: median kappa, 4.24 v 3.43 mg/dL; median lambda, 4.04 v 3.09 mg/dL) and strongly predicted NHL in a dose-response manner up to 2 to 5 years before diagnosis/selection (eg, NHL risk 3.76-fold higher with kappa concentration at least 2.00 times the upper limit of normal, and 8.13-fold higher with lambda concentration at least 2.00 times the upper limit of normal compared with normal levels). In contrast, IgG, IgM, and IgA levels were similar in patients and controls. M proteins were detected in only two patients with NHL (3%) and in nine controls (4%), and they were not significantly associated with NHL risk. CONCLUSION Elevated FLCs may represent sensitive markers of polyclonal B-cell activation and dysfunction and could be useful for identifying HIV-infected persons at increased NHL risk. PMID:20048176

    Purpose Previous studies have reported that survivors of non-Hodgkin lymphoma (NHL) have an increased risk of developing cutaneous melanoma; however, risks associated with specific treatments and immune-related risk factors have not been quantified. Patients and Methods We evaluated second melanoma risk among 44,870 1-year survivors of first primary NHL diagnosed at age 66 to 83 years from 1992 to 2009 and included in the Surveillance, Epidemiology, and End Results-Medicare database. Information on NHL treatments, autoimmune diseases, and infections was derived from Medicare claims. Results A total of 202 second melanoma cases occurred among survivors of NHL, including 91 after chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) and 111 after other NHL subtypes (cumulative incidence by age 85 years: CLL/SLL, 1.37%; other NHL subtypes, 0.78%). Melanoma risk after CLL/SLL was significantly increased among patients who received infused fludarabine-containing chemotherapy with or without rituximab (n = 18: hazard ratio [HR], 1.92; 95% CI, 1.09 to 3.40; n = 10: HR, 2.92; 95% CI, 1.42 to 6.01, respectively). Significantly elevated risks also were associated with T-cell activating autoimmune diseases diagnosed before CLL/SLL (n = 36: HR, 2.27; 95% CI, 1.34 to 3.84) or after CLL/SLL (n = 49: HR, 2.92; 95% CI, 1.66 to 5.12). In contrast, among patients with other NHL subtypes, melanoma risk was not associated with specific treatments or with T-cell/B-cell immune conditions. Generally, infections were not associated with melanoma risk, except for urinary tract infections (CLL/SLL), localized scleroderma, pneumonia, and gastrohepatic infections (other NHLs). Conclusion Our findings suggest immune perturbation may contribute to the development of melanoma after CLL/SLL. Increased vigilance is warranted among survivors of NHL to maximize opportunities for early detection of melanoma. PMID:26240221

    Epidemiological studies performed over the last decade have demonstrated a positive association between persistent, hepatitis B surface antigen (HBsAg)-positive hepatitis B virus (HBV) infection and B-cell non-Hodgkin lymphoma (NHL), with HBV-infected patients having a 2-3-fold higher risk to develop NHL than non-infected patients. Moreover, there is evidence that also occult HBV infection (HBsAg-negative, HBV DNA-positive) associates with NHL. An association with HBV infection may exist also for other hematological malignancies, but available evidence is much less persuasive than for NHL. In this review article we will discuss available results on the association between HBsAg-positive HBV infection and NHL, as well as the significance of other serological markers of HBV infection in these subjects. We will also discuss the possible etiopathogenic role of HBV, and propose a multifactorial model for lymphomagenesis. Experimental evidence for multifactorial etiopathogenesis has been obtained in recent years for HBV-associated hepatocellular carcinoma (HCC), and we suggest that a similar model may apply to HBV-associated lymphoma as well. Eventually, we will also address some unresolved questions. Two of these are of particular relevance. First, do HBV-positive NHL patients show regression of their hematologic malignancy upon antiviral therapy? A positive answer would represent a direct demonstration of the necessary etiological role of the virus in the development of NHL, as has been shown previously for HCV-associated lymphomas. Second, if HBV plays a necessary role in lymphomagenesis, then expansion of HBV vaccination is expected to reduce the number of incident NHL cases, even though this effect might become evident only after a long time interval. Studies in those countries which have introduced universal HBV vaccination about two decades ago, like Italy, may soon provide results on this important point. PMID:22432084

    Non-Hodgkin lymphoma (NHL) is the most commonly diagnosed hematologic cancer of adults in the United States, with the vast majority of NHLs deriving from malignant B lymphocytes that express cell surface CD20. CD20 immunotherapy (rituximab) is widely used to treat NHL, even though the initial effectiveness of rituximab varies widely among patients and typically wanes over time. The mechanisms through which lymphomas initially resist or gain resistance to immunotherapy are not well established. To address this, a preclinical mouse model system was developed to comprehensively identify lymphoma transcriptomic changes that confer resistance to CD20 immunotherapy. The generation of spontaneous primary and familial lymphomas revealed that sensitivity to CD20 immunotherapy was not regulated by differences in CD20 expression, prior exposure to CD20 immunotherapy, or serial in vivo passage. An unbiased forward exome screen of these primary lymphomas was used to validate the utility of this expansive lymphoma cohort, which revealed that increased lymphoma galectin-1 (Gal-1) expression strongly correlated with resistance to immunotherapy. Genetically induced lymphoma Gal-1 expression ablated antibody-dependent lymphoma phagocytosis in vitro and lymphoma sensitivity to CD20 immunotherapy in vivo. Human NHLs also express elevated Gal-1 compared with nonmalignant lymphocytes, demonstrating the ability of this preclinical model system to identify molecular targets that could be relevant to human therapy. This study therefore established a powerful preclinical model system that permits the comprehensive identification of the dynamic lymphoma molecular network that drives resistance to immunotherapy.

    A retrospective study of head and neck lymphomas in Papua Newguinean children between the age of 0 and 12 years for a 10-year period has been attempted. A total of 67 cases are recorded. This constitutes approximately 23% of all lymphomas seen during this period. There was a male predominance in all groups. Non-Hodgkin's lymphomas (NHL) comprised of 92% of which Burkitt's lymphomas (BL) predominate (64%). Almost 50% of these cases seen were in the age group of 5-8 years. In BL, cheek swelling and upper jaw involvement are the common modes of presentation, however, in 23% of cases advanced disease with multiple sites of involvement are noted. In other NHL cases, approximately 55% presented with cervical lymphadenopathy only, maxillary sinus was affected in four cases and orbit in two cases. Histological evaluation of NHL cases excluding BL revealed two high grade, nine intermediate grade and seven low grade tumours. Hodgkin's lymphoma (HL) comprised of 8%. All cases of HL presented with cervical lymphadenopathy. Standard therapeutic modalities for lymphomas with multidrug chemotherapy, surgery and radiotherapy were followed. Proper prognostic evaluation following the treatment had not been possible in view of poor patient compliance and lack of follow up. PMID:9663945

    Purpose: Standards for the reporting of radiotherapy details in randomized controlled trials (RCTs) are lacking. Although radiotherapy (RT) is an important component of curative therapy for Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL), we postulated that RT reporting may be inadequate in Phase III HL and NHL trials. Methods and Materials: We searched PubMed and the Cochrane registry for reports of RCTs involving RT and either HL or NHL published between 1998 and 2007. We screened 133 titles and abstracts to identify relevant studies. We included a total of 61 reports. We assessed these reports for the presence of six quality measures: target volume, radiation dose, fractionation, radiation prescription, quality assurance (QA) process use, and adherence to QA (i.e., reporting of major or minor deviations). Results: Of 61 reports, 23 (38%) described the target volume. Of the 42 reports involving involved-field RT alone, only 8 (19%) adequately described the target volume. The radiation dose and fractionation was described in most reports (54 reports [89%] and 39 reports [64%], respectively). Thirteen reports specified the RT prescription point (21%). Only 12 reports (20%) described using a RT QA process, and 7 reports (11%) described adherence to the QA process. Conclusion: Reporting of RT in HL and NHL RCTs is deficient. Because the interpretation, replication, and application of RCT results depend on adequate description and QA of therapeutic interventions, consensus standards for RT reporting should be developed and integrated into the peer-review process.

    The effectiveness of the novel hematopoietic stem cell mobilizing agent plerixafor was evaluated in nationwide compassionate use programs in 13 European countries. A total of 580 poor mobilizers with non-Hodgkin's lymphoma (NHL), Hodgkin's lymphoma (HL) and multiple myeloma (MM) were enrolled. All patients received plerixafor plus granulocyte CSF with or without chemotherapy. Overall, the collection yield was significantly higher in MM patients (>2.0 × 10(6) CD34+ cells/kg: 81.6%; >5.0 × 10(6) CD34+ cells/kg: 32.0%) than in NHL patients (>2.0 × 10(6) CD34+ cells/kg: 64.8%; >5.0 × 10(6) CD34+ cells/kg: 12.6%; P<0.0001) and also significantly higher in HL patients (>2.0 × 10(6) CD34+ cells/kg: 81.5%; >5.0 × 10(6) CD34+ cells/kg: 22.2%) than in NHL patients (P=0.013). In a subgroup analysis, there were no significant differences in mobilization success comparing patients with diffuse large B-cell lymphoma, follicular lymphoma and mantle cell lymphoma. Our data emphasize the role of plerixafor in poor mobilizers, but further strategies to improve the apheresis yield especially in patients with NHL are required. PMID:22080971

    Peripheral T-cell lymphomas (PTCL) are a diverse group of rare non-Hodgkin lymphomas (NHL) that carry a poor prognosis and are in need of effective therapies. Alisertib (MLN8237) an investigational agent that inhibits Aurora A Ser/Thr kinase has shown activity in PTCL patients. Here we demonstrate that aurora A and B are highly expressed in T-cell lymphoma cell lines. In PTCL patient samples aurora A was positive in 3 of 24 samples and co-expressed with aurora B. Aurora B was positive in tumor cells in 22 of 32 samples. Of the subtypes of PTCL, aurora B was over-expressed in PTCL (NOS) [73%], T-NHL (100%), ALCL (Alk-Neg) [100%] and AITL [100%]. Treatment with MLN8237 inhibited PTCL cell proliferation in CRL-2396 and TIB-48 cells with an IC50 of 80-100 nM. MLN8237 induced endo-reduplication in a dose and time dependent manner in PTCL cell lines leading to apoptosis demonstrated by flow cytometry and PARP-cleavage at concentrations achieved in early phase clinical trials. Moreover, inhibition of HisH3 and aurora A phosphorylation was dose dependent and strongly correlated with endo-reduplication. The data provide a sound rationale for aurora inhibition in PTCL as a therapeutic modality and warrants clinical trial evaluation. PMID:23153524

    Laboratory (LTLS) and clinical (CTLS) tumour lysis syndrome (TLS) are frequent complications in newly diagnosed children with advanced mature B cell non-Hodgkin lymphoma (B-NHL). Rasburicase, compared to allopurinol, results in more rapid reduction of uric acid in paediatric patients at risk for TLS. However, the safety and efficacy of rasburicase for the treatment or or prevention of TLS has not been prospectively evaluated. Children with newly diagnosed stage III-IV, bone marrow(+) and/or central nervous system(+) mature B-NHL received hydration and rasburicase prior to cytoreductive therapy. Rasburicase was safe and well-tolerated and there were no grade III-IV toxicities probably or directly related to rasburicase. Patients with an initial lactate dehydrogenase ≥2× upper limit of normal had a significantly elevated uric acid level (P = 0·005), increased incidence of TLS (P-0·005) and lower glomerular filtration rate (GFR; P < 0·001). Following rasburicase, there was only a 9% and 5% incidence of LTLS and CTLS, respectively. Furthermore, there was a significant improvement in estimated GFR from Day 0 to Day 7 following rasburicase (P = 0·0007) and only 1·3% of patients required new onset renal assisted support after rasburicase administration. A TLS strategy incorporating rasburicase prior to cytoreductive chemotherapy proved safe and effective in preventing new onset renal failure and was associated with a significant improvement in GFR.

    Cutaneous lymphomas are uncommon. They must be distinguished from secondary skin manifestations of primary nodal lymphomas. Primary cutaneous lymphomas are divided into B-cell- and T-cell cutaneous lymphoma and commonly have good prognosis. Therapy is based on the stage of the disease. Since cure is not possible, the aim of treatment is to control the disease and reduce symptoms. A variety of new and promising therapeutic modalities have been introduced in recent years.

    Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma (NHL), representing approximately 25% of diagnosed NHL. DLBCL is heterogeneous disease both clinically and genetically. The 3 most common chromosomal translocations in DLBCL involve the oncogenes BCL2, BCL6, and MYC. Double hit (DH) DLBCL is an aggressive form in which MYC rearrangement is associated with either BCL2 or BCL6 rearrangement. Patients typically present with a rapidly growing mass, often with B symptoms. Extranodal disease is often present. Though there is a paucity of prospective trials in this subtype, double hit lymphoma (DHL) has been linked to very poor outcomes when patients are treated with standard R-CHOP. There is, therefore, a lack of consensus regarding the standard treatment for DHL. Several retrospective analyses have been conducted to help guide treatment of this disease. These suggest that DA EPOCH-R may be the most promising regimen and that achievement of complete resolution predicts better long-term outcomes. PMID:27115017

    Because of their remarkable effectiveness in radioimmunotherapy (RIT), 2 anti-CD20 monoclonal antibody (MAb) drugs, one labeled with indium 111 for imaging or yttrium 90 for therapy, and another labeled with iodine I 131 for imaging and therapy, have been approved for use in patients with non-Hodgkin's lymphoma (NHL). Successful RIT for lymphomas is due in large part to the rapid and efficient binding of the targeted MAb to lymphoma cells. Carcinomas are more difficult to access, necessitating novel strategies matched with radionuclides with specific physical properties. Because there are many radionuclides from which to choose, a systematic approach is required to select those preferred for a specific application. Thus far, radionuclides with g emissions for imaging and particulate emissions for therapy have been investigated. Radionuclides of iodine were the first to be used for RIT. Many conventionally radioiodinated MAbs are degraded after endocytosis by target cells, releasing radioiodinated peptides and amino acids. In contrast, radiometals have been shown to have residualizing properties, advantageous when the MAb is localized in malignant tissue. b-emitting lanthanides like those of 90Y, lutetium 177, etc. have attractive combinations of biologic, physical, radiochemical, production, economic, and radiation safety characteristics. Other radiometals, such as copper-67 and copper-64, are also of interest. a-emitters, including actinium-225 and bismuth-213, have been used for therapy in selected applications. Evidence for the impact of the radionuclide is provided by data from the randomized pivotal phase III trial of 90Y ibritumomab tiuxetan (Zevalin) in patients with NHL; responses were about 2 times greater in the 90Y ibritumomab tiuxetan arm than in the rituximab arm. It is clear that RIT has emerged as a safe and efficient method for treatment of NHL, especially in specific settings. PMID:15498149

    Background/Objectives To understand the possible effect of modifiable health behaviors on the prognosis of the increasing number of non-Hodgkin lymphoma (NHL) survivors, we examined the pre-diagnostic intake of major food groups with all-cause and NHL-specific survival in the Multiethnic Cohort (MEC). Subjects/Methods This analysis included 2,339 participants free of NHL at cohort entry and diagnosed with NHL as identified b cancer registries during follow-up. Deaths were ascertained through routine linkages to state and national death registries. Cox proportional hazards regression was applied to estimate hazard ratios (HR) and 95% confidence intervals (CI) for overall and NHL-specific mortality according to prediagnostic intake of vegetables, fruits, red meat, processed meat, fish, legumes, dietary fiber, dairy products, and soy foods assessed by food frequency questionnaire. Results The mean age at diagnosis was 71.8±8.5 years. During 4.5±4.1 years of follow-up, 1,348 deaths, including 903 NHL-specific deaths, occurred. In multivariable models, dairy intake was associated with higher all-cause mortality (highest vs. lowest tertile: HR=1.14, 95% CI 1.00–1.31, ptrend=0.03) and NHL-specific (HR=1.16, 95% CI 0.98–1.37) mortality. Legume intake above the lowest tertile was related to significant 13–16% lower all-cause and NHL-specific mortality, while red meat and fish intake in the intermediate tertiles was associated with lower NHL-specific mortality. No association with survival was detected for the other food groups. Conclusion These data suggest that pre-diagnostic dietary intake may not appreciably contribute to NHL survival although the higher mortality for dairy products and the better prognosis associated with legumes agree with known biologic effects of these foods.

    Gastrointestinal lymphoma is the most common form of extranodal lymphoma, accounting for 30%–40% of cases. The most commonly involved site is the stomach (60%–75% of cases), followed by the small bowel, ileum, cecum, colon and rectum. The most common histological subtypes are diffuse large B-cell lymphoma (DLBCL) and marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT). Helicobacter pylori infection has been implicated in the pathogenesis of MALT gastric lymphoma, but its role in gastric diffuse large B-cell non-Hodgkin's lymphoma (NHL) is controversial. The therapeutic approach for patients with gastric NHL has been revised over the last 10 years. Conservative treatment with anthracycline-based chemotherapy alone or in combination with involved-field radiotherapy has replaced gastrectomy as standard therapy in cases with DLBCL. Additionally, MALT lymphomas are mainly treated with antibiotics alone, which can induce lasting remissions in those cases associated with H. pylori infection. Nevertheless, various therapeutic aspects for primary gastric lymphomas are still controversial and several questions remain unanswered. Among others, the role of rituximab, consolidation radiotherapy as well as H. pylori eradication in histological aggressive subtypes warrants better clarification. PMID:18647965

    Results of pediatric lymphoma treatment have improved markedly over the past 30 years. In Hodgkin's lymphoma, the 5 year event-free survival (EFS) was 81.5% in a retrospective study. In the ALB-NHL03 study, the 5 year EFS according to clinical stage in patients with lymphoblastic T-cell lymphoma (T-LBL) was 70.6% for stage III and 88.9% for stage IV. In mature B-cell lymphoma, the B-NHL03 study indicated that the 4 year EFS according to treatment group was 94% for group 1, 98% for group 2, 84% for group 3, and 78% for group 4. Moreover, the 2 year EFS rate was 81% in Japanese advanced stage patients based on the international ALCL99 study. Thus, EFS >80% was achieved in any subtype of pediatric lymphoma. With regard to refractory or recurrent lymphoma, however, treatment methods for improvement of the survival rate in these patients still need to be developed. Also the difference between child, and adolescent and young adult patients still needs to be clarified, and treatment protocols developed. Although lymphoma treatment does not greatly change according to country, it does differ between other countries and Japan for some subtypes of lymphoma. In particular, the results of treatment of stage III T-LBL in Japan are worse than those in the USA and Europe. The priority in future studies will be to collect data on these differences, and the reasons for these differences. PMID:26096060

    Canine breast cancer (BC) and human BC are the most prevalent tumors in female dogs and humans, respectively. Several studies have indicated that canine BC is a good model for human BC. Unlike breast carcinomas, human primary breast lymphoma (PBL) is a rare tumor, but no case of canine PBL has been reported thus far. The current study presents a case of canine MC of the primary non-Hodgkin lymphoma (NHL) type for the first time and subsequently questions the theory of considering it as a model for human PBL. A 2-cm tumor was surgically removed from the left caudal abdominal mammary gland of a 6-year-old female dog of the terrier breed. Microscopic examination did not show any sign for the epithelial origin of the tumor. By contrast, histomorphological view and molecular pathological evaluation by immunohistochemistry showed that the tumor was of the diffuse large B-cell lymphoma (DLBCL) type [cluster of differentiation 19(+) (CD19(+)), CD20(+), CD10(+), B-cell lymphoma 6(+), CD3(-), CD15(-)]. According to the World Health Organization classification, DLBCL is considered to be an NHL. Canine NHL is common in dogs and certain investigators believe that the biological behavior and clinical course is extremely similar to human NHL, and therefore, consider it as a model of human NHL. To the best of our knowledge, the current study is the first report of canine PBL. As the most significantly reported human PBL histotype is the DLBCL type, the histomorphological and immunophenotyping characteristics of canine PBL in the study considerably match with human PBL and raise the hypothesis that it can be a model for human PBL.

    The prevalence of lymphoma in primary immunodeficiency cases and autoimmune diseases, as well as on a background of immunodeficiency following organ transplants, is increasing. The lymphoma treatment success rate is known to be a low prognosis. Our study aimed to emphasize the low survival rates in immunodeficient vs. immunocompetent lymphoma patients and also to investigate the effect of rituximab in patients with ataxia telangiectasia and other immunodeficiencies. We summarized the clinical characteristics and treatment results of 17 cases with primary immunodeficiency that developed non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) retrospectively. Seven patients were diagnosed with ataxia-telangiectasia, two with common variable immunodeficiency, two with selective IgA deficiency, one with X-related lymphoproliferative syndrome, one with Wiskott-Aldrich syndrome, one with Epstein-Barr virus-related lymphoproliferative syndrome, one with interleukin-2-inducible T-cell kinase (ITK) deficiency, and one with lymphoma developing after autoimmune lymphoproliferative syndrome (ALPS). One patient underwent a renal transplant. Of the nine males and eight females (aged 3-12 years, median = 7) that developed lymphoma, seven were diagnosed with HL and ten with NHL (seven B-cell, three T-cell). The NHL patients were started on the Berlin-Frankfurt-Münster, POG9317, LMB-96, or R-CHOP treatment protocols with reduced chemotherapy dosages. HL cases were started on the doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and/or cyclophosphamide, vincristine, procarbazine, and prednisone (COPP) protocol, also with modified dosages. Importantly, all seven cases of HL are alive and in remission, while six of the ten NHL patients have died. Primary immunodeficiency is a strong predisposing factor for developing lymphoma. Low treatment success rates relative to other lymphomas and difficulties encountered during treatment indicate that new treatment agents are needed

    Trim-NHL proteins are defined by RING, B-Box and Coiled-coil protein motifs (referred to collectively as the Trim domain) coupled to an NHL domain. The C. elegans, D. melanogaster, mouse and human Trim-NHL proteins are potential and in several cases confirmed, E3 ubiquitin ligases. Current research is focused on identifying targets and pathways for Trim-NHL-mediated ubiquitination and in assessing the contribution of the NHL protein-protein interaction domain for function and specificity. Several Trim-NHL proteins were discovered in screens for developmental genes in model organisms; mutations in one of the family members, Trim32, cause developmental disturbances in humans. In most instances, mutations that alter protein function map to the NHL domain. The NHL domain is a scaffold for the assembly of a translational repressor complex by the Brat proto-oncogene, a well-studied family member in Drosophila. The link to translational control is common to at least four Trim-NHLs that associate with miRNA pathway proteins. So far, two have been shown to repress (Mei-P26 and Lin41) and two to promote (NHL-2, Trim32) miRNA-mediated gene silencing. In this chapter we will describe structure-function relations for each of the proteins and then focus on the lessons being learned from these proteins about miRNA functions in development and in stem cell biology.

    The results of many laboratory studies suggest that amphetamine use may lead to altered immune function and cytokine expression, both of which are implicated in HIV-related lymphomagenesis. We examined the hypothesis that use of amphetamines modifies risk of non-Hodgkin lymphoma (NHL) in HIV-infected men in the Multicenter AIDS Cohort Study. Data on amphetamine use were collected every six months during the follow-up period between 1984 and 2002. A total of 171 NHL cases were diagnosed from the 19,250 person-years accrued. Multivariable Cox models were used to estimate the effects of baseline exposures, time-varying recent exposures, and three years lagged exposures on risk of NHL adjusting for potential confounders such as demographics, use of other substances, and risky sexual behaviors. We found that weekly or more frequent use of amphetamines was associated with an increased risk of NHL, with hazard ratios of 1.75 (95% CI = 0.81–3.77) for use at baseline, 4.73 (1.41–15.81) for recent use, and 3.05 (1.19–7.82) for three years prior use. Similar associations were observed when we separately examined systemic NHL and diffuse large B-cell lymphoma. Given these observations, the impact of amphetamines on lymphomagenesis among HIV-infected populations should be assessed more thoroughly. PMID:19011979

    Summary This study described long-term outcomes of autologous hematopoietic-cell transplantation (HCT) for advanced Hodgkin (HL) and non-Hodgkin lymphoma (NHL). The study included recipients of autologous HCT for HL (N=407) and NHL (N=960) from 1990–98 who were in continuous complete remission for at least 2 years post-HCT. Median follow-up was 104 months for HL and 107 months for NHL. Overall survival at 10-years was 77% (72–82%) for HL, 78% (73–82%) for diffuse large-cell NHL, 77% (71–83%) for follicular NHL, 85% (75–93%) for lymphoblastic/Burkitt NHL, 52% (37–67%) for mantle-cell NHL and 77% (67–85%) for other NHL. On multivariate analysis, mantle-cell NHL had the highest relative-risk for late mortality (2.87 (1.70–4.87)), while the risks of death for other histologies were comparable. Relapse was the most common cause of death. Relative mortality compared to age, race and gender adjusted normal population remained significantly elevated and was 14.8 (6.3–23.3) for HL and 5.9 (3.6–8.2) for NHL at 10-years post-HCT. Recipients of autologous HCT for HL and NHL who remain in remission for at least 2-years have favorable subsequent long-term survival but remain at risk for late relapse. Compared to the general population, mortality rates continue to remain elevated at 10-years post-transplantation. PMID:19573079

    B-cell non-Hodgkin's lymphoma (B-NHL) is one of the most common types of cancer in the world, with half of the patients dying due to the resistance or tolerance against the treatment. Thus, a novel therapeutic approach for B-NHL treatment was urgently needed. In this study, we investigated the potential of co-inhibition of Hedgehog signaling pathway (Hh) and autophagy in B-NHL therapy. We reported that vismodegib, an inhibitor of Hedgehog signaling pathway, could block the Hh pathway and induce cytotoxicity and apoptosis in B-NHL Raji cells. During this process, autophagy was activated as a response to Hh inhibition. Importantly, inhibition of autophagy potentiated the cytotoxicity and caspase 3-dependent apoptosis induced by vismodegib in B-NHL cells. Furthermore, clearance of ROS generation caused a decreased activity of autophagy and attenuated cytotoxicity in vismodegib-treated cells, while inhibition of autophagy accelerated the formation of ROS, indicating that ROS was required for vismodegib-induced autophagy and cytotoxicity in B-NHL cells. Our results demonstrated that co-inhibition of Hh pathway and autophagy could potently kill B-NHL cells and highlighted a novel approach for B-NHL therapy by co-inhibition of Hh pathway and cytoprotective autophagy.

    We evaluated the association between common immune system-altering experiences and non-Hodgkin lymphoma (NHL) risk using a case-control study of 162 like-sex twin pairs discordant for NHL, identified from the International Twin Study. Information on medical history and evidence of childhood exposure to microbes was obtained by questionnaire from 1998 to 2002. Conditional logistic regression was used to estimate odds ratios and 95% confidence intervals. Intra-twin-pair agreement between twins on individual exposures was high (76%-97%). A negative association between NHL and seasonal hay fever (odds ratio (OR) = 0.28, 95% confidence interval (CI): 0.10, 0.75) and certain allergies (OR = 0.29, 95% CI: 0.13, 0.68) was observed. The number of atopic diseases was negatively associated with NHL (P for trend = 0.0003). A history of infectious mononucleosis was negatively associated with NHL risk (OR = 0.35, 95% CI: 0.14, 0.90). NHL risk was associated with more frequent childhood exposure to microbes during early life (P for trend = 0.04). No differences in association by NHL subtype were observed, although statistical power for these comparisons was low. These observations support the hypothesis that immune-related exposures, especially atopy, are associated with decreased NHL risk. Use of the within-twin-pair study design mitigates confounding by genome, family structure, and unmeasured characteristics of early childhood factors. PMID:26271116

    Indolent Non-Hodgkin Lymphomas (iNHL) are typically B-cell malignancies and are incurable with current standard approaches. Thus, there is a demand for novel agents specific for this group of disorders. In a phase II study published by Gopal et al. in the New England Journal of Medicine, idelalisib, a small molecule inhibitor of PI3Kδ that was FDA approved in July of 2014, was shown to be effective when combined with rituximab in patients who cannot tolerate chemotherapy and as last line therapy in patients with iNHL refractory to 2 prior systemic therapies. Idelalisib demonstrated tolerable diarrhea, fatigue, nausea, pyrexia, and cough. While this novel agent is a clinically significant addition to the iNHL arsenal, further research is needed to determine its most appropriate place in iNHL therapy. PMID:25756507

    Here, we report and investigate the genomic alterations of two novel cases of Non-Hodgkin Lymphoma (NHL) in children with Williams-Beuren syndrome (WBS), a multisystem disorder caused by 7q11.23 hemizygous deletion. Additionally, we report the case of a child with NHL and a somatic 7q11.23 deletion. Although the WBS critical region has not yet been identified as a susceptibility locus in NHL, it harbors a number of genes involved in DNA repair. The high proportion of pediatric NHL reported in WBS is intriguing. Therefore, the role of haploinsufficiency of genes located at 7q11.23 in lymphomagenesis deserves to be investigated.

    The incidence rates of non-Hodgkin lymphoma (NHL) have steadily increased over the last several decades in the United States, and the temporal trends in incidence can only be partially explained by the HIV epidemic. In 1992, an international workshop sponsored by the United States National Cancer Institute concluded that there was an “emerging epidemic” of NHL and emphasized the need to investigate the factors responsible for the increasing incidence of this disease. Over the past two decades, numerous epidemiological studies have examined the risk factors for NHL, particularly for putative environmental and lifestyle risk factors, and international consortia have been established in order to investigate rare exposures and NHL subtype-specific associations. While few consistent risk factors for NHL aside from immunosuppression and certain infectious agents have emerged, suggestive associations with several lifestyle and environmental factors have been reported in epidemiologic studies. Further, increasing evidence has suggested that the effects of these and other exposures may be limited to or stronger for particular NHL subtypes. This paper examines the progress that has been made over the last twenty years in elucidating the etiology of NHL, with a primary emphasis on lifestyle factors and environmental exposures.

    Richter's transformation induces an aggressive clinical course in chronic lymphocytic leukemia (CLL). In the majority of cases, Richter's transformation manifests itself as a high-grade B-cell non-Hodgkin's lymphoma (B-NHL). However, other histological types, such as classical Hodgkin lymphoma (cHL), lymphoblastic lymphoma, hairy cell leukemia and high-grade T-cell NHL have been described previously. The present study reports a rare case of CLL with transformation into classical Hodgkin's lymphoma (cHL). The common clonal origin of CLL and cHL was documented by immunoglobulin gene rearrangement analysis performed using multiplex polymerase chain reaction. Following a review of the literature, treatment of secondary Hodgkin's lymphoma is discussed, and prognosis is often poor. PMID:26998289

    Genes encoding for arylamine N-acetyltransferase 1 and 2 (NAT1 and NAT2) have been investigated with alternate findings in relation to risk of non-Hodgkin lymphoma (NHL). We tested functional haplotype-based NAT1 and NAT2 gene polymorphisms in relation to risk of lymphoma overall and its major B cell subtypes, diffuse large B cell lymphoma (DLBCL), follicular lymphoma (FL) and chronic lymphocytic leukaemia (CLL). We used allele specific primers and multiplex PCR to detect NAT1 and NAT2 haplotypes in 248 patients with incident lymphoma and 208 population controls. We inferred the NAT1 rapid and slow acetylator and the NAT2 rapid, intermediate or slow acetylator phenotype, based on published functional data on the respective genotypes. Odds ratios and 95% confidence intervals (95% CIs) for lymphoma, B-NHL, DLBCL, FL, CLL, and other B-NHL combined associated with the inferred rapid NAT1 acetylator and with the intermediate and slow NAT2 acetylator phenotypes were estimated with unconditional and polytomous logistic regression analysis, adjusting for age, gender and education. NAT1 rapid acetylators showed a 2.8-fold excess risk (95% CI 1.5-5.2) for lymphoma (all subtypes combined). Risk was highest for CLL and FL, with significant heterogeneity detected across subtypes. Risk also increased with decreasing NAT2 acetylating capacity with no heterogeneity detected across B cell lymphoma subtypes. Risks did not vary by gender. Although poor statistical power was a major limitation in our study, larger studies and pooled analyses are warranted to test whether NAT1 and NAT2 gene polymorphisms might modulate risk of specific lymphoma subtypes through the varying metabolic activity of their products.

    Infectious etiologies have been hypothesized for Hodgkin and non-Hodgkin lymphoma (HL and NHL) in early life, but findings to date for specific lymphomas and periods of susceptibility are conflicting. We conducted the first national cohort study to examine whether season of birth, a proxy for infectious exposures in the first few months of life, is associated with HL or NHL in childhood through young adulthood. A total of 3,571,574 persons born in Sweden in 1973–2008 were followed up through 2009 to examine the association between season of birth and incidence of HL (943 cases) or NHL (936 cases). We found a sinusoidal pattern in NHL risk by season of birth (P=0.04), with peak risk occurring among birthdates in April. Relative to persons born in fall (September-November), odds ratios for NHL by season of birth were 1.25 (95% CI, 1.04–1.50; P=0.02) for spring (March-May), 1.22 (95% CI, 1.01–1.48; P=0.04) for summer (June-August), and 1.11 (95% CI, 0.91–1.35; P=0.29) for winter (December-February). These findings did not vary by sex, age at diagnosis, or major subtypes. In contrast, there was no seasonal association between birthdate and risk of HL (P=0.78). In this large cohort study, birth in spring or summer was associated with increased risk of NHL (but not HL) in childhood through young adulthood, possibly related to immunologic effects of delayed infectious exposures compared with fall or winter birth. These findings suggest that immunologic responses in early infancy may play an important role in the development of NHL. PMID:24752499

    Little information is available on cytogenetic abnormalities and their prognostic importance in childhood mature B-cell non-Hodgkin lymphoma (B-NHL). We performed a review of 79 abnormal karyotypes in childhood B-NHL treated by a uniform protocol. Del(17p) was independently associated with significantly inferior event-free survival in Burkitt or Burkitt-like lymphoma. The adverse prognosis of MYC/8q24 rearrangement, +7q or del(13q), was not observed, which had been suggested as risk factors in FAB/LMB96. Our results imply the possible existence of a biological difference among ethnicities and should be useful to narrow down the gene causing poor prognosis in childhood B-NHL. PMID:25790170

    B-cell activation biomarkers have been associated with increased risk of non-Hodgkin lymphoma (NHL) in HIV-infected populations. However, whether a similar association may exist in general populations has not been established. We conducted a case-control study within the Women’s Health Initiative Observational Study cohort to measure the B-cell activation biomarkers sCD23, sCD27, sCD30, sCD44, and CXCL13 in serum samples collected an average of 6 years before NHL diagnosis, in 491 cases and 491 controls. Using logistic regression to estimate odds ratios, we observed strong associations between NHL and markers, for all B-cell NHL and for major subtypes. Women with marker levels in the highest-versus-lowest quartile categories of CD23, CD27, CD30, or CXCL13 were at 2.8 to 5.5-fold increased risk of B-NHL. Additionally, there were significant trends of risk with increasing levels of these markers present. Associations were strongest for cases with shortest lag times between blood draw and diagnosis (<3 years). However, there were also significant associations for cases with the longest prediagnostic lag (9–13 years). Taken together, our findings indicate a prominent role for B-cell activation among postmenopausal women in the etiology of B-cell NHL and/or in processes reflective of early disease development, as early as 9 years before diagnosis.

    Background The objective was to study the association between Non-Hodgkin's Lymphoma (NHL) and occupational exposures related to long held occupations among males in six provinces of Canada. Methods A population based case-control study was conducted from 1991 to 1994. Males with newly diagnosed NHL (ICD-10) were stratified by province of residence and age group. A total of 513 incident cases and 1506 population based controls were included in the analysis. Conditional logistic regression was conducted to fit statistical models. Results Based on conditional logistic regression modeling, the following factors independently increased the risk of NHL: farmer and machinist as long held occupations; constant exposure to diesel exhaust fumes; constant exposure to ionizing radiation (radium); and personal history of another cancer. Men who had worked for 20 years or more as farmer and machinist were the most likely to develop NHL. Conclusion An increased risk of developing NHL is associated with the following: long held occupations of faer and machinist; exposure to diesel fumes; and exposure to ionizing radiation (radium). The risk of NHL increased with the duration of employment as a farmer or machinist. PMID:18687133

    A population based case-control study was conducted to determine whether risk of non-Hodgkin's lymphoma (NHL) in the absence of HIV infection is related to the previous use of tobacco, alcohol or recreational drugs. A total of 378 residents of Los Angeles County who were diagnosed with high- or intermediate-grade NHL were compared with individually age-, race- and sex-matched neighbourhood control subjects with regard to history of use of tobacco products, alcohol and ten specific recreational drugs. Risk of NHL among women decreased with increased consumption of alcoholic beverages (trend P = 0.03), with risk 50% lower among those consuming five or more drinks per week than among non-drinkers. Cocaine, amphetamines, Quaaludes and lysergic acid diethylamide (LSD) were each associated with a significantly increased risk of NHL in men with risk greater among those with more frequent use of these drugs. Confounding factors could not be excluded in these findings. The use of multiple types of drugs was also associated with a significantly increased risk of NHL in men (trend P = 0.005) with risk greatest among those using five or more types of drugs (odds ratio = 5.8, 95% confidence limits = 1.2-28.4); among these drugs, cocaine use appeared to account for the elevated risk of NHL among men based on multivariable analyses.

    Polychlorinated biphenyls (PCBs) are synthetic chlorinated hydrocarbons that have extensively polluted the environment and bioaccumulated in the food chain. PCBs have been deemed to be probable carcinogens by the Environmental Protection Agency, and exposure to high levels of PCBs has been consistently linked to increased risk of non-Hodgkin lymphoma (NHL). In the present article we present a forensic epidemiologic evaluation of the causal relationship between NHL and elevated PCB levels via application of the Bradford-Hill criteria. Included in the evaluation is a meta-analysis of the results of previously published case-control studies in order to assess the strength of association between NHL and PCBs, resulting in an odds ratio in which the lowest percentile PCB concentration (quartile, quintile, or tertile) has been compared with the highest percentile concentration in the study groups. The weight-adjusted odds ratio for all PCB congeners was 1.43 with a 95% confidence interval of 1.31 to 1.55, indicating a statistically significant causal association with NHL. Because of the lack of an unexposed comparison group, a rationale for the use of a less than 2.0 relative risk causal contribution threshold is presented herein, including an ecologic analysis of NHL incidence and PCB accumulation (as measured by sales volume) over time. The overall results presented here indicate a strong general causal association between NHL and PCB exposure. PMID:22577404

    The establishment of Clusters of Differentiation for T- and B-lymphoid cells during International Workshops on Human Leukocyte Differentiation Antigens prompted the authors to evaluate the immunophenotypes in 160 cases of non-Hodgkin's lymphoma (NHL). In this group, 130 were of B-lymphocyte lineage (117 by monotypic immunoglobulin expression), and 30 of T-cell lineage. In the B-NHL series the expression of immunoglobulin isotypes, B-cell maturation/differentiation antigens of CD9, CD10, CD19-24, CD37, and CD38 (OKT10), HLA-DR and peanut agglutinin binding showed no significant relationship with histopathologic diagnosis as defined by the Kiel classification. Of the T-cell markers, CD5, CD6, and CD7 showed lineage promiscuity by their presence on some B-NHL. Conversely, the authors grouped the cases according to phenotypes (either CD antigens or immunoglobulin isotypes) which occur in distinct stages of (physiologic) B-cell maturation/differentiation. Eighty-six of the 130 cases could be fitted according to CD phenotype expression. This approach did not yield a significant relationship between phenotype and individual histopathologic categories either. The staging by CD phenotype and by immunoglobulin isotype yielded different results in this respect. Most B-NHL had an intermediate stage of B-cell maturation/differentiation. In the T-NHL series most cases showed a phenotype (CD1-CD8, CD38, TdT, and peanut agglutinin binding capacity) compatible with mature T-lymphocyte characteristics. The exceptions were lymphoblastic convoluted lymphomas, which exhibited an immature immunophenotype. It is concluded that NHL in distinct histopathologic categories are heterogeneous in immunologic phenotypes, and that the immunophenotype of lymphoma cells has no evident association with that of their presumed counterparts in physiologic cell maturation/differentiation.

    There are no prospective studies of aggressive non-Hodgkin lymphoma (NHL) treated with CHOP in sub-Saharan Africa. We enrolled adults with aggressive NHL in Malawi between June 2013 and May 2015. Chemotherapy and supportive care were standardized, and HIV+ patients received antiretroviral therapy (ART). Thirty-seven of 58 patients (64%) were HIV+. Median age was 47 years (IQR 39–56), and 35 (60%) were male. Thirty-five patients (60%) had stage III/IV, 43 (74%) B symptoms, and 28 (48%) performance status ≥2. B-cell NHL predominated among HIV+ patients, and all T-cell NHL occurred among HIV- individuals. Thirty-one HIV+ patients (84%) were on ART for a median 9.9 months (IQR 1.1–31.7) before NHL diagnosis, median CD4 was 121 cells/μL (IQR 61–244), and 43% had suppressed HIV RNA. HIV+ patients received a similar number of CHOP cycles compared to HIV- patients, but more frequently developed grade 3/4 neutropenia (84% vs 31%, p = 0.001), resulting in modestly lower cyclophosphamide and doxorubicin doses with longer intervals between cycles. Twelve-month overall survival (OS) was 45% (95% CI 31–57%). T-cell NHL (HR 3.90, p = 0.017), hemoglobin (HR 0.82 per g/dL, p = 0.017), albumin (HR 0.57 per g/dL, p = 0.019), and IPI (HR 2.02 per unit, p<0.001) were associated with mortality. HIV was not associated with mortality, and findings were similar among patients with diffuse large B-cell lymphoma. Twenty-three deaths were from NHL (12 HIV+, 11 HIV-), and 12 from CHOP (9 HIV+, 3 HIV-). CHOP can be safe, effective, and feasible for aggressive NHL in Malawi with and without HIV. PMID:26934054

Twenty-three deaths were from NHL (12 HIV+, 11 HIV-), and 12 from CHOP (9 HIV+, 3 HIV-). CHOP can be safe, effective, and feasible for aggressive NHL in Malawi with and without HIV. PMID:26934054

    Genetic variations in human leukocyte antigens (HLA) are critical in host responses to infections, transplantation, and immunological diseases. We previously identified associations with non-Hodgkin lymphoma (NHL) and the HLA-DRB1*01:01 allele and extended ancestral haplotype (AH) 8.1 (HLA-A*01-B*08-DR*03-TNF-308A). To illuminate how HLA alleles and haplotypes may influence NHL etiology, we examined potential interactions between HLA-DRB1*01:01 and AH 8.1, and a wide range of NHL risk factors among 685 NHL cases and 646 controls from a United States population-based case-control study. We calculated odds ratios and 95% confidence intervals by HLA allele or haplotype status, adjusted for sex, age, race and study center for NHL and two major subtypes using polychotomous unconditional logistic regression models. The previously reported elevation in NHL risk associated with exposures to termite treatment and polychlorinated biphenyls were restricted to individuals who did not possess HLA-DRB1*01:01. Previous associations for NHL and DLBCL with decreased sun exposure, higher BMI, and autoimmune conditions were statistically significant only among those with AH 8.1, and null among those without AH 8.1. Our results suggest that NHL risk factors vary in their association based on HLA-DRB1*01:01 and AH 8.1 status. Our results further suggest that certain NHL risk factors may act through a common mechanism to alter NHL risk. Finally, control participants with either HLA-DRB1*01:01 or AH 8.1 reported having a family history of NHL twice as likely as those who did not have either allele or haplotype, providing the first empirical evidence that HLA associations may explain some of the well-established relationship between family history and NHL risk.

    Targeted radiation therapy or radioimmunotherapy has been an important recent advance in the treatment of patients with B-cell non-Hodgkin's lymphoma (NHL). Yttrium 90-labeled ibritumomab tiuxetan (Zevalin) comprises the murine monoclonal antibody ibritumomab, the linker chelator tiuxetan, and the radiolabeled isotope yttrium 90. Yttrium 90 ibritumomab tiuxetan has been shown to be efficacious in the treatment of B-cell NHL. Initial phase I/II trials established the therapeutic dose of ibritumomab tiuxetan for low-grade NHL to be 0.4 mCi/kg, or 0.3 mCi/kg for patients with mild thrombocytopenia. Currently, there are many ongoing trials of ibritumomab tiuxetan with different dose schedules and dose intensities in combination with chemotherapy and autologous or allogeneic stem cell transplantation in an attempt to improve response rate and duration and to study its effectiveness in other B-cell lymphomas including mantle cell lymphoma, and chronic lymphocytic leukemia. This article reviews the ongoing trials with 90Y ibritumomab tiuxetan. Radioimmunotherapy has great promise, and the safe incorporation of 90Y ibritumomab tiuxetan into treatment will hopefully result in improved survival for patients with NHL. PMID:15498147

    Abstract As normal healthy skeletal muscle does not contain lymphoid tissue, extra nodal lymphoma involving multiple muscles is rare, as well. This study reports a case of non-Hodgkin's lymphoma (NHL) of multiple skeletal muscles involvement and a review of differential diagnosis of it. A 37-year-old female presented to our hospital after being diagnosed with NHL for 7 months. She had received six courses of cyclophosphamide hydroxydaunorubicin oncovin prednisolone etoposide (CHOPE) chemotherapy. Then she felt pain and noticed swelling on her left calf. The fluorodeoxyglucose (18FDG) positron emission tomography (PET)/computed tomography (CT) image showed abnormal focal FDG uptake in hypo-pharynx, which was the primary NHL and also in multiple groups of muscles in whole body. As the patient has history NHL, lymphoma of multiple muscle involvement was suspected. Finally, an ultrasound-guided tissue biopsy was performed on the left calf and histological examination yielded lymphomatous cells infiltration in the left gastrocnemius. Through this report, we emphasize that a multidisciplinary team approach with clinician, radiologist, and pathologist is essential for proper diagnosis, staging, and management of such rare lesions.

    We conducted a population-based case-control study in Connecticut women to test the hypothesis that genetic variations in DNA repair pathway genes may modify the relationship between body mass index (BMI) and risk of non-Hodgkin lymphoma (NHL). Compared to those with BMI < 25, women with BMI ≥ 25 had significantly increased risk of NHL among women who carried BRCA1 (rs799917) CT/TT, ERCC2 (rs13181) AA, XRCC1 (rs1799782) CC, and WRN (rs1801195) GG genotypes, but no increase in NHL risk among women who carried BRCA1 CC, ERCC2 AC/CC, XRCC1 CT/TT, and WRN GT/TT genotypes. A significant interaction with BMI was only observed for WRN (rs1801195, P=0.004) for T-cell lymphoma and ERCC2 (rs13181, P=0.002) for diffuse large B-cell lymphoma. The results suggest that common genetic variation in DNA repair pathway genes may modify the association between BMI and NHL risk. PMID:23619945

    Lymphoma is a malignant disease with two forms: Hodgkin’s lymphoma (HL) and non-Hodgkin’s lymphoma (NHL). Non-Hodgkin’s lymphoma is diagnosed in extranodal sites in 40% of cases, and the head and neck region is the second most affected, with an incidence of 11–33%, while HL has a very low incidence in extranodal sites (1–4%). The aim of this study was to identify the oral manifestations of lymphoma through a systematic literature review, which we conducted using the PubMed, Lilacs, Embase, and Cochrane Library databases. We found 1456 articles, from which we selected 73. Among the intraoral findings, the most frequent were ulcerations, pain, swelling, and tooth mobility, while the extraoral findings included facial asymmetry and cervical, submandibular, and submental lymphadenopathy. Among the few studies reporting imaging findings, the most cited lesions included hypodense lesions with diffuse boundaries, bone resorptions, and tooth displacements. The publications reviewed highlight gaps in the areas of early detection, diagnosis, and proper treatment. PMID:27594910

    Prospective studies of lifestyle and non-Hodgkin lymphoma (NHL) are conflicting, and some are inconsistent with case-control studies. The Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial was used to evaluate risk of NHL and its subtypes in association with anthropometric factors, smoking, and alcohol consumption in a prospective cohort study. Lifestyle was assessed via questionnaire among 142,982 male and female participants aged 55–74 years enrolled in the PLCO Trial during 1993–2001. Hazard ratios and 95% confidence intervals were calculated using Cox proportional hazards regression. During 1,201,074 person-years of follow-up through 2006, 1,264 histologically confirmed NHL cases were identified. Higher body mass index (BMI; weight (kg)/height (m)2) at ages 20 and 50 years and at baseline was associated with increased NHL risk (Ptrend < 0.01 for all; e.g., for baseline BMI ≥30 vs. 18.5–24.9, hazard ratio = 1.32, 95% confidence interval: 1.13, 1.54). Smoking was not associated with NHL overall but was inversely associated with follicular lymphoma (ever smoking vs. never: hazard ratio = 0.62, 95% confidence interval: 0.45, 0.85). Alcohol consumption was unrelated to NHL (drinks/week: Ptrend = 0.187). These data support previous studies suggesting that BMI is positively associated with NHL, show an inverse association between smoking and follicular lymphoma (perhaps due to residual confounding), and do not support a causal association between alcohol and NHL.

    Comparative data regarding the distribution of non-Hodgkin lymphoma (NHL) subtypes in North Africa, the Middle East and India (NAF/ME/IN) is scarce in the literature. In this study, we evaluated the relative frequencies of NHL subtypes in this region. Five expert haematopathologists classified 971 consecutive cases of newly-diagnosed NHL from five countries in NAF/ME/IN. After review, 890 cases (91·7%) were confirmed to be NHL and compared to 399 cases from North America (NA). The male-to-female ratio was significantly higher in NAF/ME/IN (1·8) compared to NA (1·1; P< 0·05). The median ages of patients with low-grade (LG) and high-grade (HG) B-NHL in NAF/ME/IN (56 and 52 years, respectively) were significantly lower than in NA (64 and 68 years, respectively). In NAF/ME/IN, a significantly lower proportion of LG B-NHL (28·4%) and a higher proportion of HG B-NHL (58·4%) were found compared to NA (56·1% and 34·3%, respectively). Diffuse large B-cell lymphoma was more common in NAF/ME/IN (49·4%) compared to NA (29·3%), whereas follicular lymphoma was less common in NAF/ME/IN (12·4%) than in NA (33·6%). In conclusion, we found significant differences in NHL subtypes and clinical features between NAF/ME/IN and NA. Epidemiological studies are needed to better understand the pathobiology of these differences. PMID:26684877

    Animal and human studies support a protective effect of Vitamin D sufficiency related to malignancy by uncovering paracrine and autocrine effects of extra-renal 25(OH)D activation including: regulation of cell cycle proliferation, apoptosis induction, and increased cell differentiation signaling. Recent epidemiologic studies demonstrate a reduction in non-Hodgkin lymphoma (NHL) risk with increased sunlight exposure. As sunlight is a major vitamin D source, it has been suggested that vitamin D status may mediate this observed association. This review provides a comprehensive discussion of the current epidemiologic evidence with regard to the investigation of an association between vitamin D status and NHL risk. PMID:19832043

    Pediatric Non-Hodgkin Lymphomas (NHL) are a diverse group of malignancies and as such treatment can vary based on the different biological characteristics of each malignancy. Significant advancements are being made in the treatment and outcomes of this group of malignancies. This is in large part due to novel targeted drug therapies that are being used in combination with traditional chemotherapy. Here, we discuss several new lines of therapy that are being developed or are in current use for pediatric patients with NHL. PMID:27213405

    Lymphoma of the heart and pericardium may develop in up to 25% of patients with disseminated nodal disease, but primary cardiac lymphoma is rare. The majority are diffuse large B-cell lymphomas, which arise in immunocompetent older individuals, men twice as often as women. Subsets are found in immunocompromised patients, including those with HIV-AIDS or allograft recipients. Cardiac lymphomas tend to arise in the wall of the right heart, especially right atrium, with contiguous infiltration of epicardium and pericardium. Pericardial implants and effusions are common. The disease is often multifocal in the heart, but cardiac valves are usually spared. PMID:27265603

    Background: Exposure to organochlorines has been examined as a potential risk factor for non-Hodgkin lymphoma (NHL), with inconsistent results that may be related to limited statistical power or to imprecise exposure measurements. Objective: Our purpose was to examine associations between organochlorine concentrations in prediagnostic adipose tissue samples and the risk of NHL. Methods: We conducted a case–cohort study using a prospective Danish cohort of 57,053 persons enrolled between 1993 and 1997. Within the cohort we identified 256 persons diagnosed with NHL in the population-based nationwide Danish Cancer Registry and randomly selected 256 subcohort persons. We measured concentrations of 8 pesticides and 10 polychlorinated biphenyl (PCB) congeners in adipose tissue collected upon enrollment. Associations between the 18 organochlorines and NHL were analyzed in Cox regression models, adjusting for body mass index. Results: Incidence rate ratios and confidence intervals (CIs) for interquartile range increases in concentrations of dichlorodiphenyltrichlorethane (DDT), cis-nonachlor, and oxychlordane were 1.35 (95% CI: 1.10, 1.66), 1.13 (95% CI: 0.94, 1.36), and 1.11 (95% CI: 0.89, 1.38), respectively, with monotonic dose–response trends for DDT and cis-nonachlor based on categorical models. The relative risk estimates were higher for men than for women. In contrast, no clear association was found between NHL and PCBs. Conclusion: We found a higher risk of NHL in association with higher adipose tissue levels of DDT, cis-nonachlor, and oxychlordane, but no association with PCBs. This is the first study of organochlorines and NHL using prediagnostic adipose tissue samples in the exposure assessment and provides new environmental health evidence that these organochlorines contribute to NHL risk.

    Background B cell non Hodgkin lymphomas account for the majority of lymphomas in Uganda. The commonest is endemic Burkitt lymphoma, followed by diffuse large-B-cell lymphoma (DLBCL). There has been an increase in incidence of malignant lymphoma since the onset of the HIV/AIDS pandemic. However, the possible linkages of HHV8 and EBV to the condition of impaired immunity present in AIDS are still not yet very clearly understood. Objectives 1. To describe the prevalence of Epstein-Barr virus, Human Herpes virus 8 and Human Immunodeficiency Virus-1 in B cell non Hodgkin lymphoma biopsy specimens in Kampala, Uganda. 2. To describe the histopathology of non Hodgkin lymphoma by HIV serology test result in Kampala, Uganda Method Tumour biopsies specimens from 119 patients with B cell non Hodgkin lymphoma were classified according to the WHO classification. Immunohistochemistry was used for detection of HHV8 and in situ hybridization with Epstein Barr virus encoded RNA (EBER) for EBV. Real time and nested PCR were used for the detection of HIV. The patients from whom the 1991-2000 NHL biopsies had been taken did not have HIV serology results therefore 145 patients biopsies where serology results were available were used to describe the association of HIV with non Hodgkin lymphoma type during 2008-2009. Results In this study, the majority (92%) of the Burkitt lymphomas and only 34.8% of the diffuse large B cell lymphomas were EBV positive. None of the precursor B lymphoblastic lymphomas or the mantle cell lymphomas showed EBV integration in the lymphoma cells. None of the Burkitt lymphoma biopsies had HIV by PCR. Of the 121 non Hodgkin B cell lymphoma patients with HIV test results, 19% had HIV. However, only 1(0.04%) case of Burkitt lymphoma had HIV. All the tumours were HHV8 negative. Conclusions The majority of the Burkitt lymphomas and two fifths of the diffuse large B cell lymphomas had EBV. All the tumours were HHV8 negative. Generally, the relationship of NHL and HIV

    Background The incidence of non-Hodgkin lymphoma (NHL) in early life has increased in recent decades, but the relevant risk factors remain largely unknown. We examined perinatal and family risk factors for NHL in childhood through young adulthood. Methods We conducted a national cohort study of 3 571 574 individuals born in Sweden in 1973–2008 who were followed for incidence of NHL through 2009 (ages 0–37 years). Detailed information on perinatal and family characteristics and NHL diagnoses were obtained from national birth and cancer registries. Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between perinatal and family variables and NHL; P values are from two-sided tests. Results There were 936 NHL case patients identified in 66.3 million person-years of follow-up. Independent risk factors for NHL included family history of NHL in either a sibling (adjusted HR = 9.84; 95% CI = 2.46 to 39.41; P = .001) or parent (adjusted HR = 2.36; 95% CI = 1.27 to 4.38; P = .007); high fetal growth (for ≥2 SDs relative to 0 to <1 SD from the mean: adjusted HR = 1.64; 95% CI = 1.19 to 2.25; P = .002); older maternal age (adjusted HR for each 5-year increment = 1.11; 95% CI = 1.04 to 1.19; P trend = .004); low birth order (adjusted HR for each increment of one birth = 0.91; 95% CI = 0.84 to 0.99; P trend = .02); and male sex (adjusted HR = 1.58; 95% CI = 1.38 to 1.80; P < .001). Male sex was associated with onset of NHL before 15 years of age but not with later-onset NHL, whereas the other risk factors did not vary by age at diagnosis. No association was found between gestational age at birth, twinning, paternal age, or parental education and NHL. Conclusion In this large national cohort study, family history of NHL, high fetal growth, older maternal age, low birth order, and male sex were independent risk factors for NHL in early life.

    Non-Hodgkin lymphoma (NHL) accounts for 8–10% of all childhood cancers. NHL collectively represents various lymphoid malignancies with diverse clinicopathological and biological characteristics. In this study, we aimed to describe the epidemiological and clinicopathological characteristics and treatment outcomes of pediatric NHL patients treated at the Pediatric Oncology Unit of Zagazig University Hospital and the Benha Specialized Pediatric Hospital. We conducted a cross-sectional retrospective study by reviewing the medical records of 142 patients admitted with a diagnosis of NHL over a period of 8 years (February, 2004 to February, 2012) in these two Oncology Units. The age at presentation ranged between 2 and 15 years, with a mean ± standard deviation (SD) of 6.1±2.8 years and a male:female ratio of 1.7:1. Abdominal involvement was the most common presentation (73.2%). Burkitt's lymphoma (BL) was the most common NHL subtype (69%), followed by lymphoblastic lymphoma, diffuse large B-cell lymphoma and anaplastic large-cell lymphoma, accounting for 18.3, 10.6 and 2.1% of the cases, respectively. The majority of the patients (88.7%) had been diagnosed with advanced disease (Murphy stage III/IV). Complete remission was achieved in 120 cases (84.5%). A total of 16 patients (11.3%) succumbed to the disease during the first few months and 6 patients (4.2%) remained alive following relapse. The mean follow-up duration ± SD was 34.6±25.1 months (range, 3–84 months). The 5-year overall survival (OS) and event-free survival (EFS) rates were 88.7 and 85.1%, respectively. None of the clinical, epidemiological or pathological variables exhibited a statistically significant association with the OS or EFS. In conclusion, NHL occurs at a younger age, with a higher incidence of BL and advanced-stage disease. The outcome of NHL in our two centers was satisfactory, approaching the international rates.

    In the present study, our aim was to assess the incidence of BCL-1 gene rearrangements in formalin-fixed paraffin embedded (FFPE) tissue in patients with non-Hodgkin lymphomas (NHL). The BIOMED-2 protocol was applied to assess the BCL-1 gene rearrangements in NHL patients. PCR amplification was carried out on FFPE in 100 patients with B-cell lymphoma including 89 cases with diffused large B-cell lymphoma (DLBCL) (15 cases under 18 years old) and 11 cases with mantle cell lymphoma (MCL). Out of the 100 patients, 19 cases (19%) were identified to have concurrent translocation involving BCL-1. The significant association was seen between BCL-1 gene rearrangements and the lymphomas in patients older than 55 years (P<0.05). Out of 100 cases, 80 cases were positive and 20 cases were negative regarding CD20. No significant association was found between DLBCL lymphoma in patients under 18 years old and BCL-1 gene rearrangements (P>0.05). In addition, the positive and negative expressions of LCA/CD45 marker were 76% (76/100) and 26% (26/100), respectively. Our findings revealed that BCL-1 gene rearrangement assays using BIOMED-2 protocol can be considered as a valuable approach in detection of the lymphomas. PMID:27045402

    A retrospective analysis of 1,792 solid tissues suggestive of lymphoma, submitted over a 12-year period, was carried out and flow cytometry (FC) results were compared with histologic findings. The final histologic diagnosis of cases documented in this report is as follows: 1,270 non-Hodgkin's lymphomas (NHL); 17 composite lymphomas; four NHL plus carcinomas; five post-transplant lymphoproliferative disorders; 105 Hodgkin's lymphomas (HL); eight acute leukemias; 42 tissue cancers; and 341 non-neoplastic diseases. A strong correlation between morphology and FC data was observed among hematological malignancies (1,268/1,304, 97.2%) with the exception of HL. Among B-NHL, FC detection of clonally restricted B-cell allowed the identification of lymphomas that were not histologically clear and the differential diagnosis between follicular lymphoma and reactive hyperplasia. A high correlation level (r = 0.83; P < 0.0001) was obtained in comparing proliferation results obtained by FC and immunohistochemistry. Among T-NHL, FC detection of an aberrant phenotype direct histologic diagnosis in cases having less than 20% of neoplastic cells. In nine cases, FC suggested the need to evaluate a neoplastic population, not morphologically evident. Results show that FC routinely performed on tissue samples suspected of lymphomas is a fundamental adjunct to morphology in the diagnosis of NHL and may enhance the performance of the histologic evaluation so as to achieve the final diagnosis. To the best of our knowledge, this is the first report in the literature of a wide series of tissues also studied by FC. PMID:23325563

    Mantle cell lymphoma (MCL) is a subtype of non-Hodgkin's lymphoma (NHL) comprising around 7% of adult NHL. It is characterized by a chromosomal translocation t(11:14) and overexpression of Cyclin D1. The incidence of secondary gastrointestinal tract involvement in MCL ranges from 10 to 28% in various series. However primary gastrointestinal MCL is very rare, accounting for only 1 to 4% of primary gastrointestinal lymphomas. The most common endoscopic feature of primary intestinal MCL is multiple lymphomatous polyposis. In rare cases it presents as protruded lesions or superficial lesions. Single colonic mass presentation is an extremely infrequent presentation. MCL has an aggressive course with quick progression, and most cases are discovered in the advanced stages. Colonic biopsies with histologic examination and specific immunohistochemical staining are the gold standard for a proper diagnosis. We report a case of a single mass forming mantle cell lymphoma of the ascending colon in a 57-year-old female patient with unusual colonoscopic and radiologic features and describe the therapy the patient received, thereby adding to the spectrum of clinical presentations of this aggressive lymphoproliferative disorder.

    With the widespread use of highly active antiretroviral therapy (HAART) the incidence of systemic non-Hodgkin lymphoma (NHL) in patients infected with the Human Immunodeficiency Virus (HIV) has declined. HAART has also modified the clinical manifestations of these tumors, with a lower frequency of involvement of the central nervous system (CNS). Currently, the frequency of meningeal involvement at the time of diagnosis of NHL in HIV-infected patients varies between 3% and 5%. These figures are similar to those observed among immunocompetent hosts. The diagnosis of meningeal lymphoma relies in clinical findings, imaging techniques, and cerebrospinal fluid (CSF) examination. Flow cytometry is a diagnostic technique with a higher sensitivity and specificity than conventional cytology for the diagnosis of meningeal lymphoma. However, flow cytometry is not yet considered to be the gold standard for this purpose. Until recently, most experts recommended neuromeningeal prophylaxis for all HIV-infected patients with aggressive NHL. However, at present this prophylaxis is recommended only in patients with higher risk of CNS relapse according to different sites of involvement, stage and histological subtype. There are different regimens of prophylaxis and treatment for meningeal lymphoma. The drugs most commonly used for this purpose are methotrexate and cytosine arabinoside. However, there are other alternatives such as liposomal cytosine arabinoside that requires fewer spinal taps for drug administration and whose results are very promising. In summary, in the context of an effective HAART, HIV infected patients with NHL have a frequency of CNS involvement by lymphoma similar to that found among immunocompetent hosts. Consequently, indications and regimens for CNS prophylaxis in HIV-infected patients with NHL should not be different than those employed in the general population. Universal CNS prophylaxis should be reserved for the few patients unable to receive an

    Extranodal lymphomas (ENLs) comprise about a third of all non-Hodgkin lymphomas (NHL). Radiation therapy (RT) is frequently used as either primary therapy (particularly for indolent ENL), consolidation after systemic therapy, salvage treatment, or palliation. The wide range of presentations of ENL, involving any organ in the body and the spectrum of histological sub-types, poses a challenge both for routine clinical care and for the conduct of prospective and retrospective studies. This has led to uncertainty and lack of consistency in RT approaches between centers and clinicians. Thus far there is a lack of guidelines for the use of RT in the management of ENL. This report presents an effort by the International Lymphoma Radiation Oncology Group (ILROG) to harmonize and standardize the principles of treatment of ENL, and to address the technical challenges of simulation, volume definition and treatment planning for the most frequently involved organs. Specifically, detailed recommendations for RT volumes are provided. We have applied the same modern principles of involved site radiation therapy as previously developed and published as guidelines for Hodgkin lymphoma and nodal NHL. We have adopted RT volume definitions based on the International Commission on Radiation Units and Measurements (ICRU), as has been widely adopted by the field of radiation oncology for solid tumors. Organ-specific recommendations take into account histological subtype, anatomy, the treatment intent, and other treatment modalities that may be have been used before RT.

    ATM gene alterations and impaired ATM protein expression have been described in various adult lymphoproliferative malignancies, suggesting that ATM contributes to lymphomagenesis. The present study investigated the prevalence of ATM gene and ATM protein expression alterations in sporadic childhood non-Hodgkin lymphoma (NHL). Twenty-seven cases of NHL were screened for ATM mutations by denaturing high-performance liquid chromatography (DHPLC). Direct and indirect criteria, including in silico tools, were used to classify the gene alterations. The methylation status of the ATM promoter CpG island was determined in 25 samples; ATM protein expression was assessed by Western blot in 9 lymphomas. ATM alterations were detected in 12 NHLs (44%). Ten different heterozygous base substitutions were identified in 10 NHLs (37%). Five samples (19%) were found to harbor a gene alteration considered to be a mutation or a rare variant potentially pathogenic. In one case, an ATM mutation was found in the germline. Four NHLs (44%) showed reduced or absent ATM protein expression. Except for one sample, no definite genetic or epigenetic alteration was identified to account for impaired ATM protein expression. These observations document a high prevalence of ATM gene and protein expression alterations, suggesting that ATM is involved in childhood NHL. PMID:16631465

    B cell non-Hodgkin lymphomas (B-NHLs) are the most common adult hematological cancers and many remain incurable. Development of chemotherapy regimens is confounded by the prevalence of B-NHL in older, frailer patients and the chemo-protective tumor microenvironment. Although biological therapies such as rituximab have significantly improved outcomes and selective kinase inhibitors are showing promise, the rate of new drug discovery remains disappointing, the treatments expensive and long-term benefits uncertain. An alternative strategy is redeployment of available, inexpensive and non-toxic drugs. Here, we demonstrate the antiproliferative and mitochondrial superoxide (MSO) driven pro-apoptotic activities of bezafibrate (BEZ) and medroxyprogesterone acetate (MPA) against B-NHL cells, with a bias toward MZL, in the presence and absence of the microenvironmental signal CD40L. Our study is the first to confirm the presence of CD40L within the lymph node of B-NHL and its capacity to drive B-NHL proliferation. These findings implicate BEZ + MPA as a potential therapeutic strategy in B-NHL. PMID:24996440

    2014-01-01

    This paper describes results from a systematic review and a series of meta-analyses of nearly three decades worth of epidemiologic research on the relationship between non-Hodgkin lymphoma (NHL) and occupational exposure to agricultural pesticide active ingredients and chemical groups. Estimates of associations of NHL with 21 pesticide chemical groups and 80 active ingredients were extracted from 44 papers, all of which reported results from analyses of studies conducted in high-income countries. Random effects meta-analyses showed that phenoxy herbicides, carbamate insecticides, organophosphorus insecticides and the active ingredient lindane, an organochlorine insecticide, were positively associated with NHL. In a handful of papers, associations between pesticides and NHL subtypes were reported; B cell lymphoma was positively associated with phenoxy herbicides and the organophosphorus herbicide glyphosate. Diffuse large B-cell lymphoma was positively associated with phenoxy herbicide exposure. Despite compelling evidence that NHL is associated with certain chemicals, this review indicates the need for investigations of a larger variety of pesticides in more geographic areas, especially in low- and middle-income countries, which, despite producing a large portion of the world’s agriculture, were missing in the literature that were reviewed.

    B cell non-Hodgkin's lymphomas (B-NHLs) consist of a wide spectrum of entities and consequently have varied clinical courses. Like many other malignancies, each of the B-NHL depend on their microenvironment for growth and survival; therefore, understanding the factors involved in their tissue localisation is likely to have implications for therapies designed to treat B-NHL. This review summarises the chemokines, integrins and sphingosine-1 phosphate receptors involved in normal B cell location and distribution within the lymphoid tissues (lymph nodes, spleen and bone marrow). It also provides a précis of what is known about these factors in the disease state: i.e., in some subtypes of B-NHL. PMID:24788871

    2013-01-01

    Background Non-Hodgkin’s Lymphomas (NHL) are common in African children, with endemic Burkitt’s lymphoma (BL) being the most common subtype. While the role of Epstein-Barr Virus (EBV) in endemic BL is known, no data are available about clinical presentations of NHL subtypes and their relationship to Human Immunodeficiency Virus (HIV) infection and Epstein Barr Virus (EBV) load in peripheral blood of children in north-western, Tanzania. Methods A matched case control study of NHL subtypes was performed in children under 15 years of age and their respective controls admitted to Bugando Medical Centre, Sengerema and Shirati district designated hospitals in north-western, Tanzania, between September 2010 and April 2011. Peripheral blood samples were collected on Whatman 903 filter papers and EBV DNA levels were estimated by multiplex real-time PCR. Clinical and laboratory data were collected using a structured data collection tool and analysed using chi-square, Fisher and Wilcoxon rank sum tests where appropriate. The association between NHL and detection of EBV in peripheral blood was assessed using conditional logistic regression model and presented as odds ratios (OR) and 95% confidence intervals (CI). Results A total of 35 NHL cases and 70 controls matched for age and sex were enrolled. Of NHLs, 32 had BL with equal distribution between jaw and abdominal tumour, 2 had large B cell lymphoma (DLBCL) and 1 had NHL-not otherwise specified (NHL-NOS). Central nervous system (CNS) presentation occurred only in 1 BL patient; 19 NHLs had stage I and II of disease. Only 1 NHL was found to be HIV-seropositive. Twenty-one of 35 (60%) NHL and 21 of 70 (30%) controls had detectable EBV in peripheral blood (OR = 4.77, 95% CI 1.71 – 13.33, p = 0.003). In addition, levels of EBV in blood were significantly higher in NHL cases than in controls (p = 0.024). Conclusions BL is the most common childhood NHL subtype in north-western Tanzania. NHLs are not associated

    A significant association between lymphomas and HLA alleles has been shown in previous studies. However, the frequency of HLA alleles and haplotypes has not been studied in Turkish lymphoma patients. We studied HLA-A, -B, -DRB1 alleles and haplotypes in 80 adult lymphomas and 360 unrelated normal subjects by PCR-SSOP method using Luminex technology. The allele frequencies of HLA-A*29, B*07, and DRB1*11 were higher in patients with Hodgkin's lymphoma (HL) compared with the controls [OR; 5.65 (95%CI; 2.16-14.81), P=0.001], [OR; 3.00 (95%CI; 1.50-5.99), P=0.003)], and [OR; 1.80 (95%CI; 1.08-3.01), P=0.002); respectively]. In patients with non-Hodgkin's lymphoma (NHL) HLA-B*51 and DRB1*04 allele frequencies were higher than controls [OR; 2.25 (95%CI; 1.27-4.00), P=0.007] and [OR; 2.14 (95%CI; 1.20-3.78), P=0.01]. The most frequently observed haplotypes were A*02 B*35 DRB1*11 (7.50% vs. 1.89%) in HL patients, A*02 B*51 DRB1*11 (5.00% vs. 1.96%) in NHL patients, and A*02 B*35 DRB1*13 (2.19%) in the controls. We detected four haplotypes specific to NHL, five haplotypes to HL patients. Seven haplotypes were unique to controls. Our findings suggest that in HL patients, HLA-A*29, B*07, and DRB1*11 alleles, and in NHL patients, HLA-B*51 and DRB1*04 alleles might be presumptive predisposing factors. PMID:27063556

    ONC201/TIC10 is a small molecule initially discovered by its ability to coordinately induce and activate the TRAIL pathway selectively in tumor cells and has recently entered clinical trials in adult advanced cancers. The anti-tumor activity of ONC201 has previously been demonstrated in several preclinical models of cancer, including refractory solid tumors and a transgenic lymphoma mouse model. Based on the need for new safe and effective therapies in pediatric non-Hodgkin's lymphoma (NHL) and the non-toxic preclinical profile of ONC201, we investigated the in vitro efficacy of ONC201 in non-Hodgkin's lymphoma (NHL) cell lines to evaluate its therapeutic potential for this disease. ONC201 caused a dose-dependent reduction in the cell viability of NHL cell lines that resulted from induction of apoptosis. As expected from prior observations, induction of TRAIL and its receptor DR5 was also observed in these cell lines. Furthermore, dual induction of TRAIL and DR5 appeared to drive the observed apoptosis and TRAIL expression was correlated linearly with sub-G1 DNA content, suggesting its potential role as a biomarker of tumor response to ONC201-treated lymphoma cells. We further investigated combinations of ONC201 with approved chemotherapeutic agents used to treat lymphoma. ONC201 exhibited synergy in combination with the anti-metabolic agent cytarabine in vitro, in addition to cooperating with other therapies. Together these findings indicate that ONC201 is an effective TRAIL pathway-inducer as a monoagent that can be combined with chemotherapy to enhance therapeutic responses in pediatric NHL.

    The prognosis of non-Hodgkin's lymphoma (NHL) in childhood has improved steadily in the last 2 decades. This is primarily the result of increasingly effective chemotherapy regimens tailored to defined and relatively homogeneous prognostic categories and tested in prospective clinical trials. Surgical excision remains of prognostic benefit only when near-total resection can be performed without delay of chemotherapy. The role of radiation therapy is now limited to the treatment of overt central nervous system (CNS) lymphoma, disease unresponsive to chemotherapy, and certain emergencies. Effective 'prophylactic' treatment of the CNS has been achieved in most series by intrathecal and systemic chemotherapy alone. The most relevant modality of treatment is chemotherapy and a very large number of protocols have been published. The origins of current multi-agent regimens stem both from early experience with cyclophosphamide in endemic Burkitt's lymphoma and from therapeutic studies of acute lymphoblastic leukaemia. Sub-stratification of non-localized NHL has produced protocols designed for either lymphoblastic (mostly T cell) or non-lymphoblastic (mostly B cell) categories. While the cure rate for lymphoblastic lymphoma now exceed 70%, the non-localized non-lymphoblastic disease remains a major obstacle to cure. These patients frequently present with large abdominal primaries and are prone to regional as well as hematogenous dissemination. In particular, involvement of the CNS is now considered to be the most adverse prognostic variable in this group. Recently, highly intensive regimens are addressing these obstacles. On the other hand, NHL defined as localized has been shown to be curable in up to 95% of children with the use of simple chemotherapy regimens as short as 6 months in duration. Salvage of patients who relapse during or after chemotherapy remains bleak but cures are possible with regimens incorporating bone marrow transplantation from either an autologous or

    Purpose Genetic polymorphisms in DNA repair genes and hair dye use may both have a role in the development of non-Hodgkin lymphoma (NHL). We aimed to examine the interaction between variants in DNA repair genes and hair dye use with risk of NHL in a population-based case– control study of Connecticut women. Methods We examined 24 single nucleotide polymorphisms in 16 DNA repair genes among 518 NHL cases and 597 controls and evaluated the associations between hair dye use and risk of overall NHL and common NHL subtypes, stratified by genotype, using unconditional logistic regression. Results Women who used hair dye before 1980 had a significantly increased risk of NHL, particularly for the follicular lymphoma (FL) subtype, but not for diffuse large B-cell lymphoma. The following genotypes in combination with hair dye use before 1980 were associated with FL risk: BRCA2 rs144848 AC+CC [odds ratio (OR) (95 % confidence interval (CI)) 3.28(1.27–8.50)], WRN rs1346044 TT [OR(95 % CI) 2.70(1.30–5.65)], XRCC3 rs861539 CT+TT [OR(95 % CI) 2.76(1.32–5.77)], XRCC4 rs1805377 GG [OR(95 % CI) 2.07(1.10–3.90)] and rs1056503 TT [OR(95 % CI) 2.17(1.16–4.07)], ERCC1 rs3212961 CC [OR(95 % CI) 1.93(1.00–3.72)], RAD23B rs1805329 CC [OR(95 % CI) 2.28(1.12–4.64)], and MGMT rs12917 CC, rs2308321 AA, and rs2308327 AA genotypes [OR(95 % CI) 1.96(1.06–3.63), 2.02(1.09–3.75), and 2.23(1.16–4.29), respectively]. In addition, a significant interaction with risk of overall NHL was observed between WRN rs1346044 and hair dye use before 1980 (pinteraction = 0.032). Conclusions Our results indicated that genetic variation in DNA repair genes modifies susceptibility to NHL in relation to hair dye use, particularly for the FL subtype and in women who began using hair dye before 1980. Further studies are needed to confirm these observations. PMID:25178586

    Background Benzene is a known occupational carcinogen associated with increased risk of hematologic cancers, but the relationships between quantity of passive benzene exposure through residential proximity to toxic release sites, duration of exposure, lag time from exposure to cancer development, and lymphoma risk remain unclear. Methods We collected release data through the Environmental Protection Agency’s Toxics Release Inventory (TRI) from 1989 to 2003, which included location of benzene release sites, years when release occurred, and amount of release. We also collected data on incident cases of non-Hodgkin lymphoma (NHL) from the Georgia Comprehensive Cancer Registry (GCCR) for the years 1999–2008. We constructed distance-decay surrogate exposure metrics and Poisson and negative binomial regression models of NHL incidence to quantify associations between passive exposure to benzene and NHL risk and examined the impact of amount, duration of exposure, and lag time on cancer development. Akaike’s information criteria (AIC) were used to determine the scaling factors for benzene dispersion and exposure periods that best predicted NHL risk. Results Using a range of scaling factors and exposure periods, we found that increased levels of passive benzene exposure were associated with higher risk of NHL. The best fitting model, with a scaling factor of 4 kilometers (km) and exposure period of 1989–1993, showed that higher exposure levels were associated with increased NHL risk (Level 4 (1.1–160 kilograms (kg)) vs. Level 1: risk ratio 1.56 [1.44–1.68], Level 5 (>160 kg) vs. Level 1: 1.60 [1.48–1.74]). Conclusions Higher levels of passive benzene exposure are associated with increased NHL risk across various lag periods. Additional epidemiological studies are needed to refine these models and better quantify the expected total passive benzene exposure in areas surrounding release sites. PMID:26949112

    Background: Although case–control studies conducted to date have largely affirmed the relationship between polychlorinated biphenyls (PCBs) and non-Hodgkin lymphoma (NHL), occupational cohort studies of PCB-exposed workers have been generally interpreted as negative, thereby raising doubts about a potential causal association. A common theme of immune dysregulation unifies many of NHL’s strongest risk factors, and several authors have posited that subclinical immune dysregulation may increase NHL risk by decreasing host resistance, reducing control of cellular proliferation and differentiation, and diminishing tumor surveillance mechanisms. Objectives: The goals of this review were a) to evaluate the epidemiological research examining the association between PCB exposure and NHL and discuss the contribution to the weight of evidence of case–control studies and occupational cohort studies; and b) to summarize the evidence for immune dysregulation as a means by which PCBs may cause NHL. Methods: We performed a literature search using PubMed and seven additional online biomedical and toxicological referencing libraries to identify literature published through August 2011. Discussion and Conclusions: Overall, we conclude that the weight of evidence supports a causal role of PCBs in lymphomagenesis. The strongest epidemiological evidence for the relationship between PCBs and NHL comes from case–control studies conducted among the general population. Epidemiological and toxicological data demonstrating immunosuppressive and inflammatory effects of PCBs further contribute to the weight of evidence by providing a plausible explanation for how PCBs can cause NHL through immune dysregulation.

    Checkpoint with FHA and Ring Finger (CHFR) is a checkpoint protein that reportedly initiates a cell cycle delay in response to microtubule stress during prophase in mitosis, which has become an interesting target for understanding cancer pathogenesis. Recently, aberrant methylation of the CHFR gene associated with gene silencing has been reported in several cancers. In the present study, we examined the expression of CHFR in B-cell non-Hodgkin lymphoma (B-NHL) in vitro and in vivo. Our results showed that the expression level of CHFR mRNA and protein was reduced in B-NHL tissue samples and B cell lines. Furthermore, CHFR methylation was detected in 39 of 122 B-NHL patients, which was not found in noncancerous reactive hyperplasia of lymph node (RH) tissues. CHFR methylation correlated with the reduced expression of CHFR, high International Prognostic Index (IPI) scores and later pathologic Ann Arbor stages of B-NHL. Treatment with demethylation reagent, 5-Aza-dC, could eliminate the hypermethylation of CHFR, enhance CHFR expression and cell apoptosis and inhibit the cell proliferation of Raji cells, which could be induced by high expression of CHFR in Raji cells. Our results indicated that aberrant methylation of CHFR may be associated with the pathogenesis, progression for B-NHL, which might be a novel molecular marker as prognosis and treatment for B-NHL.

    Hepatitis C virus (HCV) is a global health problem affecting a large fraction of the world’s population: This virus is able to determine both hepatic and extrahepatic diseases. Mixed cryoglobulinemia, a B-cell “benign” lymphoproliferative disorders, represents the most closely related as well as the most investigated HCV-related extrahepatic disorder. Since this virus is able to determine extrahepatic [non-Hodgkin’s lymphoma (NHL)] as well as hepatic malignancies (hepatocellular carcinoma), HCV has been included among human cancer viruses. The most common histological types of HCV-associated NHL are the marginal zone, the lymphoplasmacytic and diffuse large cell lymphomas. The role of the HCV in the pathogenesis of the B-cell lymphoproliferative disorders is confirmed also by the responsiveness of the NHL to antiviral therapy. The purpose of this review is to provide an overview of the recent literature and a meta analysis of the epidemiology data, to explain the role of HCV in the development of NHL’s lymphoma. Furthermore, the possibility to treat these HCV-related NHL with the antiviral therapy or with other therapeutic options, like chemotherapy, is also discussed. PMID:26807206

    Objective To describe cases of lymphoma associated with anti-TNF therapy, identify risk factors, estimate the incidence and compare risks for different anti-TNF agents. Methods We designed a national prospective registry (RATIO) from 2004 to 2006, for collecting all cases of lymphoma in French patients receiving anti-TNF therapy, whatever the indication. We conducted a case-control analysis including two controls treated with anti-TNF per case and an incidence study of lymphoma with the French population used as reference.. Results We collected 38 cases of lymphoma, 31 non-Hodgkin’s lymphoma (NHL) (26 B-cell and 5 T-cell), 5 Hodgkin’s lymphoma (HL) and 2 Hodgkin’s-like lymphoma. Epstein-Barr virus (EBV) was detected in 2 of 2 Hodgkin’s-like lymphoma, 3 of 5 HL and one NHL. Patients receiving adalimumab or infliximab had a higher risk than those treated with etanercept: SIR = 4.1 (2.3–7.1) and 3.6 (2.3–5.6) versus 0.9 (0.4– 1.8). The exposure to adalimumab or infliximab versus etanercept was an independent risk factor for lymphoma in the case-control study: odds ratio=4.7 (1.3– 17.7) and 4.1 (1.4–12.5), respectively. The sex and age- adjusted incidence rate of lymphoma was 42.1 per 100,000 patient-years. The standardized incidence ratio (SIR) was 2.4 (95% confidence interval [CI] 1.7–3.2). Conclusion Some lymphomas associated with immunosuppression may occur in patients receiving anti TNF therapy, and the risk of lymphoma is higher with monoclonal-antibody therapy than with soluble-receptor therapy.

    Although initial rituximab-containing chemotherapies achieve high response rates, indolent B-cell non-Hodgkin lymphoma (B-NHL), such as follicular lymphoma (FL), is still incurable. Therefore, new effective agents with novel mechanisms are anticipated. In this multicentre phase II study, patients with relapsed/refractory indolent B-NHL and mantle cell lymphoma (MCL) received vorinostat 200 mg twice daily for 14 consecutive days in a 21-d cycle until disease progression or unacceptable toxicity occurred. The primary endpoint was overall response rate (ORR) in FL patients and safety and tolerability in all patients. Secondary endpoints included progression-free survival (PFS). Fifty-six eligible patients were enrolled; 50 patients (39 with FL, seven with other B-NHL, and four with MCL) were evaluable for ORR, and 40 patients had received rituximab-containing prior chemotherapeutic regimens. For the 39 patients with FL, the ORR was 49% [95% confidence interval (CI): 32·4, 65·2] and the median PFS was 20 months (95% CI: 11·2, 29·7). Major toxicities were manageable grade 3/4 thrombocytopenia and neutropenia. Vorinostat offers sustained antitumour activity in patients with relapsed or refractory FL with an acceptable safety profile. Further investigation of vorinostat for clinical efficacy is warranted.

    The ESHAP regimen, a combination of the chemotherapeutic drugs etoposide, methylprednisolone (solumedrol), high-dose cytarabine (ara-C), and cisplatin, has been shown to be active against refractory or relapsed non-Hodgkin's lymphoma (NHL) in therapeutic trials. We undertook this study to determine whether this regimen would be effective and tolerable in Korean patients. A total of 40 patients with refractory or relapsed NHL (8 indolent and 32 aggressive) were enrolled in this study. The overall response rate was 70% (95% confidence interval; 59.8-89.7%); 22.5% of patients achieved a complete response and 47.5% a partial response. The median survival duration was 12 months (95% confidence interval; 5.9-18.1 months) and the median duration of progression-free survival was 9 months (95% confidence interval; 1.1-16.9 months). The median survival duration of patients with relapsed NHL was longer than that of patients with refractory lymphoma (15 months vs 4 months, p=0.02). Myelosuppression was the most frequent complication and treatment-related mortality was noted in two patients. These results suggest that the ESHAP regimen is effective in patients with relapsed NHL who have a sensitive disease. The role of ESHAP chemotherapy in discriminating patients who are more likely to benefit from a subsequent transplant should be evaluated in the future. PMID:12378012

    Transplant outcomes of autologous or allogeneic stem cell transplantation (SCT) have not been elucidated as a single cohort in non-Hodgkin lymphoma (NHL). We analyzed the outcomes of 270 adult recipients receiving auto (n=198) or allo-SCT (n=72) for NHL between year 2000 and 2010. Five-year overall survival for B-cell and T-cell NHL were 58% and 50%, respectively (allo-SCT 51% vs. 54% for B and T-cell NHL, and auto-SCT 60% vs. 47% for B and T-cell lymphoma, respectively) (p=NS). In multivariate analysis, number of chemotherapy regimens and disease status pre-SCT were independently associated with long-term outcome after SCT (for both auto and allo-SCT). We conclude that based on patient selection and disease related factors, the type of transplantation offered to patients can achieve long term survival highlighting the importance of further improvement in disease control and reducing procedure related mortality. The role of transplantation needs to be reevaluated in the era of targeted therapy. PMID:24096123

    Abstract The association between consumption of red and processed meat and non-Hodgkin lymphoma (NHL) remains unclear. We performed a meta-analysis of the published observational studies to explore this relationship. We searched databases in MEDLINE and EMBASE to identify observational studies which evaluated the association between consumption of red and processed meat and risk of NHL. Quality of included studies was evaluated using Newcastle-Ottawa Quality Assessment Scale (NOS). Random-effects models were used to calculate summary relative risk (SRR) and the corresponding 95% confidence interval (CI). We identified a total of 16 case–control and 4 prospective cohort studies, including 15,189 subjects with NHL. The SRR of NHL comparing the highest and lowest categories were 1.32 (95% CI: 1.12–1.55) for red meat and 1.17 (95% CI: 1.07–1.29) for processed meat intake. Stratified analysis indicated that a statistically significant risk association between consumption of red and processed meat and NHL risk was observed in case–control studies, but not in cohort studies. The SRR was 1.11 (95% CI: 1.04–1.18) for per 100 g/day increment in red meat intake and 1.28 (95% CI: 1.08–1.53) for per 50 g/day increment in processed meat intake. There was evidence of a nonlinear association for intake of processed meat, but not for intake of red meat. Findings from our meta-analysis indicate that consumption of red and processed meat may be related to NHL risk. More prospective epidemiological studies that control for important confounders and focus on the NHL risk related with different levels of meat consumption are required to clarify this association.

    Background Non-Hodgkin lymphoma (NHL) is the most common AIDS-related malignancy in developed countries. An elevated risk of developing NHL persists among HIV-infected individuals in comparison to the general population despite the advent of effective antiretroviral therapy. The mechanisms underlying the development of AIDS-related NHL (A-NHL) are not fully understood, but likely involve persistent B-cell activation and inflammation. Methods This was a nested case-control study within the ongoing prospective Multicenter AIDS Cohort Study (MACS). Cases included 47 HIV-positive male subjects diagnosed with high-grade B-cell NHL. Controls were matched to each case from among participating HIV-positive males who did not develop any malignancy. Matching criteria included time HIV+ or since AIDS diagnosis, age, race and CD4+ cell count. Sera were tested for 161 serum biomarkers using multiplexed bead-based immunoassays. Results A subset of 17 biomarkers, including cytokines, chemokines, acute phase proteins, tissue remodeling agents and bone metabolic mediators was identified to be significantly altered in A-NHL cases in comparison to controls. Many of the biomarkers included in this subset were positively correlated with HIV viral load. A pathway analysis of our results revealed an extensive network of interactions between current and previously identified biomarkers. Conclusions These findings support the current hypothesis that A-NHL develops in the context of persistent immune stimulation and inflammation. Further analysis of the biomarkers identified in this report should enhance our ability to diagnose, monitor and treat this disease. PMID:24922518

    A population-based, incidence case–control study was conducted among women in upstate New York to determine whether pesticide exposure is associated with an increase in risk of non-Hodgkin lymphoma (NHL) among women. The study involved 376 cases of NHL identified through the State Cancer Registry and 463 controls selected from the Medicare beneficiary files and state driver’s license records. Information about history of farm work, history of other jobs associated with pesticide exposure, use of common household pesticide products, and potential confounding variables was obtained by telephone interview. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using an unconditional logistic regression model. The risk of NHL was doubled (OR = 2.12; 95% CI, 1.21–3.71) among women who worked for at least 10 years at a farm where pesticides were reportedly used. When both farming and other types of jobs associated with pesticide exposure were combined, there was a progressive increase in risk of NHL with increasing duration of such work (p = 0.005). Overall cumulative frequency of use of household pesticide products was positively associated with risk of NHL (p = 0.004), which was most pronounced when they were applied by subjects themselves. When exposure was analyzed by type of products used, a significant association was observed for mothballs. The associations with both occupational and household pesticides were particularly elevated if exposure started in 1950–1969 and for high-grade NHL. Although the results of this case–control study suggest that exposure to pesticide products may be associated with an increased risk of NHL among women, methodologic limitations related to selection and recall bias suggest caution in inferring causation.

    Approximately 30,000 cases of non-Hodgkin lymphoma (NHL) occur in the equatorial belt of Africa each year. Apart from the fact that Burkitt lymphoma (BL) is very common among children and adolescents in Africa and that an epidemic of human immunodeficiency virus (HIV) infection is currently ongoing in this part of the world, very little is known about lymphomas in Africa. This review provides information regarding the current infrastructure for diagnostics in sub-Saharan Africa. The results on the diagnostic accuracy and on the distribution of different lymphoma subsets in sub-Saharan Africa were based on a review undertaken by a team of lymphoma experts on159 fine needle aspirationsamples and 467 histological samples during their visit to the African centres is presented. Among children (<18 years of age), BL accounted for 82% of all NHL, and among adults, diffuse large B-cell lymphoma accounted for 55% of all NHLs. Among adults, various lymphomas other than BL, including T-cell lymphomas, were encountered. The review also discusses the current strategies of the International Network of Cancer Treatment and Research on improving the diagnostic standards and management of lymphoma patients and in acquiring reliable clinical and pathology data in sub-Saharan Africa for fostering high-quality translational research.

    The chaperonin containing t-complex polypeptide 1 (CCT) is known to mediate folding of proteins. CCT, subunit 8 (CCT8), is the θ subunit of CCT complex chaperonin. CCT8 has been reported to be dysregulated in several tumor tissues. In this study, we investigated the role of CCT8 in B-cell non-Hodgkin's lymphoma (NHL). Clinically, the expression levels of CCT8 in reactive lymphoid hyperplasia (RLH) and B-cell NHL specimens were investigated using immunohistochemical analysis. We found that CCT8 was highly expressed in proliferating germinal center cells compared with the quiescent cells of the follicular mantle zone. Furthermore, CCT8 was highly expressed in progressive lymphomas than in indolent lymphomas. Kaplan-Meier curve showed that high expression of CCT8 was significantly associated with shorter overall survival in patients with diffuse large B-cell lymphoma. Moreover, we demonstrated that CCT8 could promote the proliferation of B-cell NHL cells. In addition, we found that CCT8 could accelerate the G1/S transition in B-cell NHL. Finally, we demonstrated that overexpression of CCT8 could reverse cell adhesion-mediated drug resistance (CAM-DR) phenotype. Our study may shed new insights into the important role of CCT8 in cancer development. PMID:27101149

    The increase in the incidence of non-Hodgkin's lymphoma (NHL) that has occurred over recent decades is expected to continue. Therapeutic options for patients with NHL have improved over the past 20 years, but almost all patients with low-grade lymphoma and approximately 50% of patients with high-grade lymphoma eventually die of their disease, regardless of the regimen used. Thus, there is a continuing need for novel therapeutic options. One such strategy is targeted radioimmunotherapy, which is an attractive approach because lymphoma cells are inherently sensitive to radiation. 90 Y-ibritumomab tiuxetan (Zevalin; Biogen Idec Inc, San Diego, CA, and Schering AG, Berlin, Germany) was the first radioimmunotherapy agent to be approved by the US Food and Drug Administration for the treatment of patients with relapsed, low-grade B-cell NHL. 90Y-ibritumomab tiuxetan comprises the murine IgG1 anti-CD20 antibody ibritumomab, covalently linked to the beta-emitter 90 Y by a chelator tiuxetan. A prospective trial comparing 90Y-ibritumomab tiuxetan with single-agent rituximab showed an overall response rate (ORR) to 90Y-ibritumomab tiuxetan of 80% (34% complete response [CR]/unconfirmed CR [CRu]) compared with 56% (20% CR/CRu) with rituximab (P = .002). Of patients achieving a CR/CRu, 32% were still in remission at 3 to 4 years of follow-up. Similar efficacy (83% ORR, 43% CR/CRu) has been reported with 90 Y-ibritumomab tiuxetan in patients with relapsed or refractory low-grade NHL with mild thrombocytopenia (platelet counts 100,000 to 149,000/mm3 ), and in patients with rituximab-refractory NHL (ORR 74% [CR 15%] compared with an ORR 32% to last rituximab treatment). Safety data compiled from patients entered into five studies have confirmed initial observations that the toxicities encountered with 90Y-ibritumomab tiuxetan therapy are mainly hematologic and transient. As part of a consolidated clinical approach to the ongoing development of 90Y-ibritumomab tiuxetan, studies are

    Oxidative damage caused by reactive oxygen species (ROS) and other free radicals is involved in carcinogenesis. It has been suggested that high vegetable and fruit intake may reduce the risk of non-Hodgkin lymphoma (NHL) as vegetables and fruit are rich in antioxidants. The aim of this study is to evaluate the interaction of vegetable and fruit intake with genetic polymorphisms in oxidative stress pathway genes and NHL risk. This hypothesis was investigated in a population-based case-control study of NHL and NHL histological subtype in Connecticut women including 513 histologically confirmed incident cases and 591 randomly selected controls. Gene-vegetable/fruit joint effects were estimated using unconditional logistic regression model. The false discovery rate method was applied to adjust for multiple comparisons. Significant interactions with vegetable and fruit intake were mainly found for genetic polymorphisms on nitric oxide synthase (NOS) genes among those with diffuse large B-cell lymphoma (DLBCL) and Follicular lymphoma (FL). Two single nucleotide polymorphisms (SNPs) in the NOS1 gene were found to significantly modify the association between total vegetable and fruit intake and risk of NHL overall, as well as the risk of follicular lymphoma (FL). When vegetables, bean vegetables, cruciferous vegetables, green leafy vegetables, red vegetables, yellow/orange vegetables, fruit, and citrus fruit were examined separately, strong interaction effects were narrowed to vegetable intake among DLBCL patients. Our results suggest that genetic polymorphisms in oxidative stress pathway genes, especially in the nitric oxide synthase genes, modify the association between vegetable and fruit intake and risk of NHL.

    Objective: Positron emission tomography and computed tomography (PET/CT) has become an important part of staging and treatment evaluation algorithms of lymphoma. We aimed to compare the results of PET/CT with bone marrow biopsy (BMB) with respect to bone marrow involvement (BMI) in patients with Hodgkin’s lymphoma (HL) and aggressive non-Hodgkin’s lymphoma (aNHL). Materials and Methods: The medical files of a total of 297 patients diagnosed with HL or aNHL and followed at the hematology clinics of 3 major hospitals in İstanbul between 2008 and 2012 were screened retrospectively and 161 patients with classical HL and aNHL were included in the study. The patients were referred for PET/CT and BMB at the initial staging. BMB was performed as the reference standard for the evaluation of BMI. Results: There were 61 (38%) HL and 100 (62%) aNHL patients. Concordant results were revealed between PET/CT and BMB in 126 patients (78%) (52 HL, 74 aNHL), 20 with positive PET/CT and BMB results and 106 with negative PET/CT and BMB results. There were discordant results in 35 patients (9 HL, 26 aNHL), 16 of them with positive BMB and negative PET/CT results and 19 of them with negative BMB and positive PET/CT results. Conclusion: We observed that PET/CT is effective to detect BMI, despite it alone not being sufficient to evaluate BMI in HL and aNHL. Bone marrow trephine biopsy and PET/CT should be considered as mutually complementary methods for detection of BMI in patients with lymphoma. In suspected focal involvement, combining biopsy and PET/CT might improve staging results. PMID:25912844

    Diffuse large B cell lymphoma (DLBCL) is recognized as the most common form of non-Hodgkin lymphoma (NHL), accounting for about 40 % of all cases of NHL. Among the cellular components of the tumor inflammatory infiltrate, T cells and mast cells have been demonstrated to be correlated with tumor angiogenesis. In this report, we have investigated CD3 and tryptase expression and their relationship with microvascular density (MVD) in DLBCL patients. Moreover, we determined the significance of CD3 expression in bulky and non-bulky disease. CD3 expression was significantly lower in bulky disease patients when compared to non-bulky ones. CD3 showed a positive correlation with tryptase and MVD, while multiple regression analysis efficaciously predicted MVD depending on CD3 and tryptase as predictors, supporting a complex interplay between these cells in sustaining tumor angiogenesis in DLBCL patients.

    Non-Hodgkin’s lymphomas (NHL) are an important variety of gastrointestinal tumors with increasing incidence and prevalence. Traditional management of NHL with chemotherapy is challenging and expanding evidence points to significant tumor response to radiation therapy (RT). However, there exists a wide range of radiation-related toxicities. Optimization of exact tumor marking coupled with minimization of the radius of radiation delivery is essential to increase patient’s tolerance and decrease side effects of the treatment. We report our experience with mantle cell lymphoma of the colon treated with precision RT after endoscopic placement of resolution clips in a “shooting target” fashion in a patient who failed conventional chemotherapy. Fourteen months after completion of RT, the patient remains in complete remission. PMID:25330785

    Plasmablastic lymphoma (PL) is a type of non-Hodgkin's lymphoma (NHL) having a strong association with immunosuppression, especially, human immunodeficiency virus (HIV) infection. It generally has a poor prognosis with most patients dying within 2 years from initial presentation, and long-term survivors are very few. We report the case of a 10-years-old child, presenting in 2003 with swelling on the right side of the face and fever of 2 months. Evaluation revealed a mass in the right palatal and upper alveolar region with extensive spread and bone destruction, regional adenopathy, mass lesion in the liver and hepatosplenomegaly without bone marrow involvement. Histopathology was suggestive of the PL and patient tested positive for HIV. He was started on high grade NHL chemotherapy protocol along with highly-active anti-retroviral therapy HAART. He responded well and is in complete remission since 8 years of completion of treatment and is on HAART. PMID:24049295

  11. Ecological study of dietary and smoking links to lymphoma

    The ecological approach is used to investigate dietary and smoking links to lymphoma. International mortality rate data for 1986 and 1994 by gender and age group are compared with national dietary supply values of various food components for up to 10 years prior to the mortality data as well as per capita cigarette consumption rates 5 and 15 years earlier. The non-fat portion of milk, 3-9 years prior to the 1986 mortality data and 4 years prior to the 1994 data, was found to have the highest association with lymphoma, with r as high as 0.89. The results imply that 70 percent of lymphoma mortality may be related to this dietary component. Cigarette smoking in 1980 was found to have a weaker association with 1994 lymphoma mortality rates, being most important for younger men and statistically insignificant for younger women. The non-fat milk result is consistent with both case-control studies and a Norwegian prospective study, and with the often-observed finding that abnormal calcium metabolism, hypercalciuria, and dysregulated calcitriol production are common in normocalcemic patients with non-Hodgkin's lymphoma (NHL). It is hypothesized that excess dietary calcium from milk is a significant risk factor for lymphoma.

    Coinciding with the increased incidence of non-Hodgkin's lymphoma (NHL) during the past decades, there has been a significant increase in the prevalence of diabetes mellitus in mainland China. We therefore evaluated whether type 2 diabetes (T2D) is associated with the risk of NHL using data from the Shanghai Men's Health Study (SMHS) and the Shanghai Women's Health Study (SWHS). The SMHS and SWHS are two on-going, prospective, population-based cohorts of more than 130 000 Chinese adults in urban Shanghai. Self-reported diabetes was recorded on the baseline questionnaire and updated in follow-up surveys. Cox regression models with T2D as a time-varying exposure were used to estimate hazard ratios and 95% confidence intervals, adjusting for covariates. After a median follow-up of 12.9 years for SWHS and 7.4 years for SMHS, 172 NHL cases were identified. Patients with T2D have a higher risk of incident NHL with a hazard ratio of 2.00 (95% confidence interval: 1.32-3.03) compared with those without diabetes. This positive association remained when the analysis was restricted to untreated diabetes or after excluding NHL cases that occurred within 3 years after the onset of diabetes. No interaction effect was found in the development of NHL between T2D and other potential risk factors. A linear inverse association was found between T2D duration and the risk of NHL in both men and women (Pfor linearity<0.01), with a highest risk of incident NHL in the first 5 years after the diagnosis of diabetes. Our study suggested that T2D might be associated with an increased risk of NHL. PMID:25793918

    Canine lymphoma has served as the ''workhorse'' for the development of veterinary oncology and as an important animal model for human non-Hodgkins lymphomas. Significant advances have been achieved in understanding the biological behavior of the disease and in its treatment. Although it is unlikely that a cure for lymphoma will be achieved, owners should be encouraged to treat their pets, provided they understand that only prolonged remissions and survivals are likely to result. Cooperative studies, employing large numbers of dogs, are needed to optimize and refine the classification scheme to provide a system with diagnostic and prognostic correlates and derive maximum benefit from therapeutic regimens. Such studies need to be prospective in nature, with a solid statistical base incorporated into their design. Rather than being content with what we have accomplished to date in treatment of canine lymphoma, the opportunity exists for the veterinary profession to make further significant contributions to the understanding and treatment of lymphoma in the dog. 10 refs., 4 tabs.

    The use of anti-CD20 monoclonal antibodies (mAbs), such as rituximab, in CD20-positive B-cell malignancies has dramatically improved the outcome of chronic lymphoid leukemia and non-Hodgkin’s lymphomas (NHL). However, the occurrence of relapse and development of rituximab-refractory disease highlight the need to develop novel anti-CD20 mAbs, with improved mechanisms of action. Obinutuzumab is the first humanized type II glycoengineered anti-CD20 mAb. In vitro and in vivo data suggested several differences compared with rituximab, including a low level of complement-dependent cytotoxicity and an increased direct nonapoptotic cell death. Moreover, the glycoengineered Fc-linked nonfucosylated oligosaccharide enhanced the Fc–Fcγ receptor (FcγR) IIIa interaction, resulting in improved antibody-dependent cellular cytotoxicity and phagocytosis. Preclinical models suggested that these differences translate into superior survival in murine lymphoma models. Phase I/II trials in monotherapy in relapsed or refractory B-cell NHL demonstrated that obinutuzumab has an acceptable safety profile, infusion-related reactions being the most common adverse event. In rituximab-refractory indolent NHL, the recent randomized phase III GADOLIN study demonstrated an improved median progression-free survival for patients treated with obinutuzumab plus bendamustine rather than bendamustine alone. Further trials are ongoing to determine the role of obinutuzumab as a first-line agent in the treatment of follicular lymphoma. PMID:27054024

    Diffuse large B-cell lymphoma (DLBCL) is the most common type of Non-Hodgkin lymphoma (NHL). DLBCL is clinically, pathologically and molecularly heterogeneous disease. Various clinical, pathological and molecular markers have been developed to characterize the disease. Based on these characterizations, new targeted agents are being investigated to optimize the treatment and improve the outcomes of DLBCL. Enhanced molecular understanding, invention of targeted agents and immunotherapy has opened the doors for improvement in the treatment of DLBCL. In this review, we will discuss various prognostic markers of DLBCL and their potential therapeutic implications. PMID:26808217

  16. The role of mitoxantrone in non-Hodgkin's lymphoma.

    The development of doxorubicin was an important advance in the treatment of patients with non-Hodgkin's lymphoma (NHL). Alternatives to doxorubicin, such as mitoxantrone (Novantrone), have less nonhematologic toxicity and could offer a therapeutic advantage in some situations if similar antilymphoma activity exists. Several combination regimens that include mitoxantrone have been shown to be active. These include mitoxantrone/ifosfamide (Ifex) and mitoxantrone/etoposide combinations as salvage therapy for aggressive lymphomas. Mitoxantrone in combination with fludarabine (Fludara) for the treatment of newly diagnosed follicular lymphomas and in combination with fludarabine and dexamethasone for relapsed/refractory follicular lymphomas has produced high complete response rates. Other evolving uses of mitoxantrone include combination therapy with cladribine (Leustatin) or rituximab (Rituxan), and as part of conditioning regimens for hematopoietic stem cell transplantation. In diffuse aggressive lymphoma, mitoxantrone, 10 mg/m2, substituted for doxorubicin, 50 mg/m2, results in a poorer response when CNOP (cyclophosphamide [Cytoxan, Neosar], mitoxantrone [Novantrone], vincristine [Oncovin], prednisone) is compared to CHOP (cyclophosphamide, doxorubicin HCl vincristine, prednsione); however, increasing the mitoxantrone dose to 12 mg/m2 in either the CNOP or CMP-BOP (cyclophosphamide, mitoxantrone, procarbazine [Matulane], bleomycin [Blenoxane], vincristine, prednisone) regimens yields results comparable to those achieved with the doxorubicin-containing regimen. Comparable results have also been observed when 10 mg/M2 of mitoxantrone was substituted for 45 mg/M2 of doxorubicin in the m-BACOD (methorexate, bleomycin, doxorubicin [Adriamycin], cyclophosphamide, vincristine, dexamethasone) regimen. Mitoxantrone is active in NHL, and combinations including mitoxantrone can be used effectively and may provide an advantage in the elderly. PMID:12017536

    Non-Hodgkin's lymphoma (NHL), which includes diffuse large B-cell lymphoma (DLBCL) and peripheral T-cell lymphoma, is a refractory malignant tumor originated from the lymphatic system. TNFAIP8L2 (TIPE2 or tumor necrosis-alpha-induced protein-8 like 2) is a negative regulator for inflammation and an inhibitor for carcinogenesis. However, whether TIPE2 plays a role in lymphomagenesis is unknown. In this study, we determined TIPE2 expression in NHL by immunohistochemistry and investigated its clinicopathological significance in DLBCL. We found that TIPE2 expression was upregulated in both DLBCL and peripheral T-cell lymphoma. But the expression of TIPE2 in T lymphomas was weaker than that in DLBCL. Interestingly, among DLBCL, TIPE2 expression was significantly stronger in the germinal center B-cell (GCB) type than in the non-GCB type. These results suggest that the expression of TIPE2 protein could be a predictor of better prognosis for DLBCL. PMID:27578327

    SUMMARY Pre-existing central nervous system (CNS) involvement may influence referral for autologous haematopoietic cell transplantation (AHCT) for patients with non-Hodgkin lymphoma (NHL). The outcomes of 151 adult patients with NHL with prior secondary CNS involvement (CNS+) receiving an AHCT were compared to 4688 patients without prior CNS lymphoma (CNS−). There were significant baseline differences between the cohorts. CNS+ patients were more likely to be younger, have lower performance scores, higher age-adjusted international prognostic index scores, more advanced disease stage at diagnosis, more aggressive histology, more sites of extranodal disease, and a shorter interval between diagnosis and AHCT. However, no statistically significant differences were identified between the two groups by analysis of progression-free survival (PFS) and overall survival (OS) at 5 years. A matched pair comparison of the CNS+ group with a subset of CNS− patients matched on propensity score also showed no differences in outcomes. Patients with active CNS lymphoma at the time of AHCT (n=55) had a higher relapse rate and diminished PFS and OS compared with patients whose CNS lymphoma was in remission (n=96) at the time of AHCT. CNS+ patients can achieve excellent long-term outcomes with AHCT. Active CNS lymphoma at transplant confers a worse prognosis. PMID:23829536

    High-dose chemotherapy and autologous stem cell transplant (ASCT) is the standard approach for chemosensitive, relapsed aggressive non-Hodgkin's lymphoma (NHL). Various conditioning regimens have been used as treatment before ASCT and disease-free (DFS) and overall survival (OS) rates range from 34 to 60% and 26 to 46%, respectively. To date, few comparative randomized trials have been performed and no regimen has demonstrated superiority to another. Reduction of disease relapse remains the major hurdle for improving patient outcome and in vitro and in vivo purging of lymphoma cells has not necessarily enhanced results. Rituximab pre-mobilization and post-transplant appear to provide better response rates with OS approaching 87-91% at 2-3 years. Newer approaches with radioimmunotherapy may raise DFS to 78% and OS to 93%, albeit with short follow-up. Advances in the conditioning regimens and supportive care have reduced transplant-related mortality to less than 10%. In this review we discuss commonly utilized conditioning regimens, describe their pros and cons and address purging and present conditioning strategies. Owing to the poor outcome with conventional chemotherapy in mantle cell, Burkitt's and T-cell lymphoma, we propose the standard approach of front-line ASCT for these high-risk lymphoma patients. Finally, we will present novel strategies, which can enhance the anti-lymphoma effect, at the same time reducing toxicity, to improve the outcome of ASCT in NHL patients. PMID:17589535

    Non-Hodgkin lymphoma (NHL) constitutes a collection of lymphoproliferative disorders with widely varying biological, histological, and clinical features. For the B cell NHLs, great progress has been made due to the addition of monoclonal antibodies and, more recently, other novel agents including B cell receptor signaling inhibitors, immunomodulatory agents, and proteasome inhibitors. Autologous hematopoietic cell transplantation (auto-HCT) offers the promise of cure or prolonged remission in some NHL patients. For some patients, however, auto-HCT may never be a viable option, whereas in others, the disease may progress despite auto-HCT. In those settings, allogeneic HCT (allo-HCT) offers the potential for cure. Over the past 10 to 15 years, considerable progress has been made in the implementation of allo-HCT, such that this approach now is a highly effective therapy for patients up to (and even beyond) age 75 years. Recent advances in conventional lymphoma therapy, peritransplantation supportive care, patient selection, and donor selection (including the use of alternative hematopoietic cell donors), has allowed broader application of allo-HCT to patients with NHL. As a result, an ever-increasing number of NHL patients over age 60 to 65 years stand to benefit from allo-HCT. In this review, we present data in support of the use of allo-HCT for patients with diffuse large B cell lymphoma, follicular lymphoma, and mantle cell lymphoma. These histologies account for a large majority of allo-HCTs performed for patients over age 60 in the United States. Where possible, we highlight available data in older patients. This body of literature strongly supports the concept that allo-HCT should be offered to fit patients well beyond age 65 and, accordingly, that this treatment should be covered by their insurance carriers.

    We reported that IL-2 activated autologous NK cells can induce, but not maintain durable remissions in lymphoma patients. We hypothesized that allogeneic NK cells may overcome class I MHC-mediated inhibition of NK cell killing. In a pilot study we evaluated infusion of haploidentical donor NK cells for anti-tumor efficacy. Six patients with advanced B-cell non-Hodgkin lymphoma (NHL) received rituximab, cyclophosphamide, and fludarabine as immunosupression to permit homeostatic NK cell expansion, followed by CD3-depleted NK cell enriched cell products followed by subcutaneous IL-2 administration (10×106 units every other day × 6 doses). At 2 months, four patients showed an objective clinical response. We observed early donor cell persistence in 2 patients (blood and in tumor-bearing node), but this was not detectable beyond 7 days. All patients demonstrated substantial increases in host regulatory T cells (Treg) after NK cell and IL-2 therapy (180±80 cells/μl vs baseline: 58±24 cells/μl, p=0.04) which may have limited donor cell expansion in vivo. These findings suggest safety and feasibility of allogeneic NK cell therapy in patients with lymphoma; however host Treg and inadequate immunodepletion may contribute to a hostile milieu for NK cell survival and expansion. Cell therapy trials should incorporate novel strategies to limit Treg expansion. PMID:20680271

    Cancer survivors are at risk of experiencing adverse physical and psychosocial effects of their cancer and its treatment. Both Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL) survivors face problems that can affect their health-related quality of life (HRQoL). The authors systematically reviewed the literature on HRQoL among HL and NHL survivors. A PubMed and PsychINFO literature search for original articles published until May 2011 was performed. Twenty-four articles, which met the predefined inclusion criteria, were subjected to a quality checklist. HL survivors showed the most problems in (role) physical, social and cognitive functioning, general health, fatigue and financial problems. In addition, HL survivors treated with a combination of therapies, with older age and female sex reported worse HRQoL. NHL survivors showed the most problems in physical functioning, appetite loss, vitality and financial problems. Having had chemotherapy was negatively associated with HRQoL, but no differences in chemotherapy regimens were found. Furthermore, in NHL survivors not meeting public exercise guidelines, HRQoL is low but can be improved with more exercise. More research on the longitudinal comparison between HL and NHL survivors and healthy controls should be performed in order to better understand the long-term (side) effects of treatment on HRQoL and possibilities to alleviate these.

    Trimodal or bimodal age-specific incidence rates for Burkitt lymphoma (BL) were observed in the United States general population, but the role of immunosuppression could not be excluded. Incidence rates, rate ratios, and 95% confidence intervals for BL and other non-Hodgkin lymphoma (NHL), by age and CD4 lymphocyte count categories, were estimated using Poisson regression models using data from the United States HIV/AIDS Cancer Match study (1980-2005). BL incidence was 22 cases per 100 000 person-years and 586 for non-BL NHL. Adjusted BL incidence rate ratio among males was 1.6× that among females and among non-Hispanic blacks, 0.4× that among non-Hispanic whites, but unrelated to HIV-transmission category. Non-BL NHL incidence increased from childhood to adulthood; in contrast, 2 age-specific incidence peaks during the pediatric and adult/geriatric years were observed for BL. Non-BL NHL incidence rose steadily with decreasing CD4 lymphocyte counts; in contrast, BL incidence was lowest among people with ≤ 50 CD4 lymphocytes/μL versus those with ≥ 250 CD4 lymphocytes/μL (incidence rate ratio 0.3 [95% confidence interval = 0.2-0.6]). The bimodal peaks for BL, in contrast to non-BL NHL, suggest effects of noncumulative risk factors at different ages. Underascertainment or biological reasons may account for BL deficit at low CD4 lymphocyte counts. PMID:20813897

    Sjogren's syndrome (SS) is characterized by an increased risk of developing non-Hodgkin's lymphoma (NHL). Optimal treatment for NHL-complicating SS is not clearly established. NHL, which expresses the CD20 antigen on tumor cell surfaces, is a disease entity candidate to treatment with anti-CD20 monoclonal antibodies. We report clinical and immunological data of a patient with SS and NHL who was treated with a regimen consisting of cyclophosphamide/vincristine/prednisone (CVP) plus rituximab. A 68-year-old women had a 26-year history of SS and autoimmune thyroiditis. The clinical course of SS was complicated with severe splenomegaly. An increased percentage of CD19+ B cells (up to 30%) was detected in peripheral blood during follow-up. Clonal rearrangement of immunoglobulin heavy chain was detected. Low-grade B marginal zone lymphoma was diagnosed (peripheral blood immunophenotype: CD19+CD20+CD23+sIg+Kappa; bone marrow immunophenotype: 25% lymphocytes; CD19+CD20+CD79A/BCL2+). She received a total of six cycles of CVP plus rituximab (375 mg/m2). Therapy was well tolerated, and B lymphocytes were depleted from the peripheral blood. Splenomegaly normalized. No evidence of neoplastic infiltration was detected in bone marrow after completion of therapy, while certain symptoms of SS (sicca and arthralgia) improved with treatment. CVP plus rituximab proved effective in a patient with SS with NHL. PMID:18270861

    It has been known that regulatory T (Treg) cells and mast cells (MCs) are involved in tumor immunity regulation, but the exact roles and mechanisms of Treg cells and MCs in B-cell non-Hodgkin's lymphoma (NHL) are incompletely defined. In the present study, we found that the number of Foxp3(+) Treg cells and CD117(+) MCs increased in B-cell NHL patients. Concomitantly, a high level of interleukin (IL)-9 was observed in the sera from B-cell NHL patients. Neutralizing IL-9 significantly inhibited tumor growth in the lymphoma model of murine, and this process was associated with down-regulation of Treg cells and MCs. Furthermore, IL-9 was also demonstrated to induce expression of MC-related genes and proliferation of MCs from the bone marrow stem cells. Collectively, our results indicate that Treg cell and MCs are involved in immunosuppression in B-cell NHL, and IL-9 is a key mediator of Treg cells and MCs in that process. These findings provide novel insight for the pathogenesis and possible therapeutic strategy of B-cell NHL. PMID:21898141

    A very unusual radiographic presentation of non-Hodgkin lymphoma (NHL) involving the maxilla is described. The patient was initially managed with antibiotics prescribed to treat what was thought to represent an odontogenic infection. After unsuccessful antibiotic therapy, the patient was referred to an oral surgery clinic where CBCT was performed. CBCT revealed an atypical generalized sclerosis of the affected bone rather than the usual lytic radiographic pattern associated with NHL. Destruction of the sinus floor with infiltration of the sinus was also present. This rare radio-opaque radiographic presentation is described in detail together with the clinical presentation and histopathological findings. The important radiographic features suggesting malignancy that were present in this atypical case of NHL are discussed. A differential diagnosis highlighting the differences between NHL, osteomyelitis and osteosarcoma is also provided. PMID:25421808

    Background: Various occupations have been associated with an elevated risk of non-Hodgkin lymphoma (NHL), but results have been inconsistent across studies. Objectives: We investigated occupational risk of NHL and of four common NHL subtypes with particular focus on occupations of a priori interest. Methods: We conducted a pooled analysis of 10,046 cases and 12,025 controls from 10 NHL studies participating in the InterLymph Consortium. We harmonized the occupational coding using the 1968 International Standard Classification of Occupations (ISCO-1968) and grouped occupations previously associated with NHL into 25 a priori groups. Odds ratios (ORs) adjusted for center, age, and sex were determined for NHL overall and for the following four subtypes: diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), and peripheral T-cell lymphoma (PTCL). Results: We confirmed previously reported positive associations between NHL and farming occupations [field crop/vegetable farm workers OR = 1.26; 95% confidence interval (CI): 1.05, 1.51; general farm workers OR = 1.19; 95% CI: 1.03, 1.37]; we also confirmed associations of NHL with specific occupations such as women’s hairdressers (OR = 1.34; 95% CI: 1.02, 1.74), charworkers/cleaners (OR = 1.17; 95% CI: 1.01, 1.36), spray-painters (OR = 2.07; 95% CI: 1.30, 3.29), electrical wiremen (OR = 1.24; 95% CI: 1.00, 1.54), and carpenters (OR = 1.42; 95% CI: 1.04, 1.93). We observed subtype-specific associations for DLBCL and CLL/SLL in women’s hairdressers and for DLBCL and PTCL in textile workers. Conclusions: Our pooled analysis of 10 international studies adds to evidence suggesting that farming, hairdressing, and textile industry–related exposures may contribute to NHL risk. Associations with women’s hairdresser and textile occupations may be specific for certain NHL subtypes. Citation: ‘t Mannetje A, De Roos AJ, Boffetta P, Vermeulen R, Benke G

    Estrogens are important immunomodulators, exerting significant effects on cell proliferation, apoptosis, cytokine production and differentiation of hematopoietic cells. Estrogen receptors are expressed on normal B and T lymphocytes, bone marrow and in leukemia and lymphoma cell lines. Epidemiologic evidence for the association of menopausal hormone use with risk of non-Hodgkin's lymphoma (NHL) has been mixed; however, all of the investigations have been observational. We analyzed the data from Women's Health Initiative hormone therapy trials where conjugated equine estrogens (CEE; 0.625 mg/d) plus medroxyprogesterone acetate (MPA; 2.5 mg/d) (n = 16,654) or CEE alone (women with prior hysterectomy) (n = 10,685) were tested against placebos and the intervention lasted a median of 5.6 years in the CEE + MPA trial and 7.2 years in the CEE alone trial. During 13 years of follow-up through September 20, 2013 383 incident NHL cases were identified. We used the intent-to-treat approach to calculate incidence rates of NHL, hazards ratios (HR) and 95% confidence intervals (CI) by treatment group. Incidence of NHL was virtually the same in the treatment and placebo groups. The HR was 1.02 (95%CI 0.74-1.39) for CEE alone, 0.98 (95% CI 0.76-1.28) for CEE+MPA, and 1.00 (95% CI 0.82-1.22) for both combined. There were no specific NHL subtypes associated with either type of the treatment, except a marginally decreased risk of plasma cell neoplasms (HR= 0.53 95% CI 0.27-1.03) in the CEE-alone group. These results do not support a role of estrogen alone or combined with progestin in the development of NHL among postmenopausal women. PMID:26365326

    Radioimmunotherapy of indolent non-Hodgkin lymphoma (NHL) has achieved objective response rates in clinical trials comparable with standard rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy, but is relatively underused in routine practice. In this article, we report our clinical experience in 142 consecutive patients who received iodine-131 rituximab radioimmunotherapy for low-grade, predominantly follicular, relapsed NHL. Objective response rates of 67%, with complete response (CR) in 50% and median overall survival of 32 months, matched the response rates in a phase 2 clinical trial of (131)I-rituximab radioimmunotherapy and compares favorably with those reported for (131)I-tositumomab or (90)Y-ibritumomab tiuxetan. Progression-free survival was 18 months overall and 32 months in CR or CR-unconfirmed patients. Our patients comprised 107 (75%) follicular lymphoma, 21 (15%) small lymphocytic lymphoma, 6 (4%) mucosa-associated lymphoid tissue/marginal zone lymphoma, and 8 (6%) mantle-cell lymphoma, with median follow-up of 32 months and 8-year overall survival of 48%. Toxicity was limited to hematologic grade 4 neutropenia, occurring in 10% and thrombocytopenia in 6%. There were no episodes of bleeding or infection requiring hospital admission. Radioimmunotherapy with (131)I-rituximab in routine clinical outpatient practice provides cost-effective, safe treatment of relapsed/refractory indolent NHL, with half of patients achieving durable, complete remission with potential for repeat radioimmunotherapy on relapse.

    In a series of 31 patients with NHL presenting in the oral region, nine lesions were in the maxilla and 5 were in the mandible, for a total of 14 (45%) lesions that arose in bone. The most common locations were the posterior regions of the maxilla (7 cases) and mandible (4 cases). Diffuse subtypes clearly predominated, 13 out of 14 cases demonstrating this pattern. Six of the cases were in children, and 4 of these qualified as Burkitt's lymphoma. In general, it was found that the statistics relating to survival of patients with jawbone lymphoma correspond closely to the findings reported for skeletal lymphomas. Despite the high incidence of diffuse patterns, 6 of these 14 patients with NHL in bone were alive with no evidence of disease 3 years or longer. PMID:6584818

    Strong evidence indicates that tumor growth can be actively controlled by the immune system, and interleukins (ILs) are known to play an influential role in immune response regulation. Moreover, inflammatory cytokines are significantly involved in lymphoma pathogenesis. We aimed to investigate serum levels of IL-4 and IL-18 in aggressive non-Hodgkin's lymphoma (A-NHL) patients and their relationship with prognostic parameters and therapy outcome. These serum factors were measured by enzyme-linked immunosorbent assay in 46 patients with pathologically verified A-NHL before and after chemotherapy, and in 20 healthy controls. No significant difference in serum IL-4 (P = 0.11) and IL-18 (P = 0.261) levels was observed between the A-NHL and controls groups. None of the prognostic parameters analyzed significantly correlated with serum IL-4 concentration, while only lactate dehydrogenase (LDH) measurements were associated with IL-18 values. Serum IL-18 was elevated in the patients with high LDH levels compared to those exhibiting normal values (P = 0.045). In addition, no correlation was found between the concentrations of serum IL-4 and IL-18 in A-NHL patients (r = 0.188, P = 0.187). While IL-18 values did not change, serum IL-4 levels decreased following chemotherapy, independently from treatment response (P = 0.002). Our study is the first to report the response of serum IL-4 levels to chemotherapy. In conclusion, although IL-4 serum concentration has no diagnostic role, it is sensitivite to standard chemotherapy in A-NHL. However, serum IL-18 measurements have no diagnostic or prognostic role in this disease. PMID:27525895

    Previous epidemiological studies suggest an inverse association between allergies, marked by elevated immunoglobulin (Ig) E levels, and non-Hodgkin lymphoma (NHL) risk. The evidence, however, is inconsistent and prospective data are sparse. We examined the association between prediagnostic total (low: <20; intermediate: 20-100; high >100 kU/l) and specific IgE (negative: <0.35; positive ≥0.35 kU/I) concentrations against inhalant antigens and lymphoma risk in a study nested within the European Prospective Investigation into Cancer and Nutrition cohort. A total of 1021 incident cases and matched controls of NHL, multiple myeloma (MM) and Hodgkin lymphoma with a mean follow-up time of 7 years were investigated. Multivariate-adjusted odds ratios (ORs) with 95% confidence intervals (CI) were calculated by conditional logistic regression. Specific IgE was not associated with the risk of MM, B-cell NHL and B-cell NHL subtypes. In contrast, total IgE levels were inversely associated with the risk of MM [high level: OR = 0.40 (95% CI = 0.21-0.79)] and B-cell NHL [intermediate level: OR = 0.68 (95% CI = 0.53-0.88); high level: OR = 0.62 (95% CI = 0.44-0.86)], largely on the basis of a strong inverse association with chronic lymphocytic leukemia [CLL; intermediate level: OR = 0.49 (95% CI = 0.30-0.80); high level: OR = 0.13 (95% CI = 0.05-0.35)] risk. The inverse relationship for CLL remained significant for those diagnosed 5 years after baseline. The findings of this large prospective study demonstrated significantly lower prediagnostic total IgE levels among CLL and MM cases compared with matched controls. This corresponds to the clinical immunodeficiency state often observed in CLL patients prior to diagnosis. No support for an inverse association between prediagnostic levels of specific IgE and NHL risk was found. PMID:25269801

    Objective(s): The aim of this study is to evaluate the role of PET-CT in identification of different patterns of extranodal involvement in Hodgkin’s disease (HD) and Non-Hodgkin’s Lymphoma (NHL) and to enlist the common sites of extranodal involvement in each histological type and compare our results with the existing literature. Methods: In this retrospective study of 281 cases of lymphomas of various histologies, we illustrate the spectrum of PET/CT features of extranodal lymphoma (ENL) of commonly involved organs and compare our result with the literature. Result: Extranodal appearance in lymphoma is strikingly varied. Diffuse large B cell lymphoma (DLBCL) is the commonest histological subtype and gastrointestinal tract is the commonest anatomical subsite in NHL. Skeletal system is the commonest site for involvement in HD. Conclusion: A broad spectrum of extranodal organs is involved in various subtype of lymphoma which can be depicted in PET-CT in the most appropriate manner. Familiarity with the pattern of involvement is essential for comprehensive management. PMID:27408858

    Hepatosplenic T-cell lymphoma (HSTCL) is a rare type of Non-Hodgkin Lymphoma (NHL), grouped under the mature or peripheral T-cell lymphomas. It is characterised by extranodal infiltration and proliferation of malignant T-cells within the sinusoids of the liver, sinuses and red pulp of the spleen, and the bone marrow. The tumour cells express CD2 and CD3, but are CD4, CD5 and CD8 negative and express a clonally restricted gamma-delta (or less commonly alpha-beta) T-cell receptor. The disease has an aggressive clinical course associated with a poor prognosis. We highlight and report three patients from South Africa with HSTCL, all of whom had hepatosplenomegaly and cytopaenias, and despite being HIV seronegative and immunocompetent, had a poor outcome, with a mean survival of 7.5 months in the two evaluable patients. This rare entity has not previously been reported from South Africa and as yet needs to be adequately characterised in a population where lymphoma is the most common haematological malignancy in adults, and where approximately two thirds of the adult lymphoma population are HIV seropositive.

    We determined treatment-related mortality (TRM), progression free survival (PFS), and overall survival (OS) after a second autologous HCT (HCT2) for patients with lymphoma relapse after a prior HCT (HCT1). Outcomes for patients with either Hodgkin lymphoma (HL, n=21) or non-Hodgkin lymphoma (NHL, n=19) receiving HCT2 reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) were analyzed. The median age at HCT2 was 38 years (range, 16–61) and 22 (58%) patients had a Karnofsky performance score less than 90. HCT2 was performed >1 year after HCT1 in 82%. The probability of TRM at day 100 was 15% (95% CI, 3–22%). The 1, 3 and 5 yr probabilities of PFS were 50% (95% CI, 34–66%), 36% (95% CI, 21–52%) and 30% (95% CI, 16–46%), respectively. Corresponding probabilities of survival were 65% (95% CI, 50–79%), 36% (95% CI, 22–52%) and 30% (95% CI, 17–46%), respectively. At a median follow up of 72 months (range, 12–124 months) after HCT2, 29 patients (73%) have died, 18 (62%) secondary to relapsed lymphoma. The outcomes of patients with HL and NHL were similar. In summary, this series represents the largest reported group of patients with relapsed lymphomas undergoing SCT2 following failed SCT1, and with long-term follow-up. Our series suggests that SCT2 is feasible in patients relapsing after prior HCT1, with a lower TRM than that reported for allogeneic transplant in this setting. HCT2 should be considered for patients with relapsed HL or NHL after HCT1 without alternative allogeneic stem cell transplant options. PMID:18640574

    >A study of drinking water contamination and leukemia and non-Hodgkin's lymphoma (NHL) incidence (1979-1987) was conducted in a 75-town study area. Comparing incidence in towns in the highest trichloroethylene (TCE) stratum (>5 microg/l) to towns without detectable TCE yielded an age-adjusted rate ratio (RR) for total leukemia among females of 1.43 (95% CI 1.07-1.90). For females under 20 years old, the RR for acute lymphocytic leukemia was 3.26 (95% CI 1.27-8.15). Elevated RRs were observed for chronic myelogenous leukemia among females and for chronic lymphocytic leukemia among males and females. NHL incidence among women was also associated with the highest TCE stratum (RR = 1.36; 95% CI 1.08-1.70). For diffuse large cell NHL and non-Burkitt's high-grade NHL among females, the RRs were 1.66 (95% CI 1.07-2.59) and 3.17 (95% CI 1.23-8.18), respectively, and 1.59 (95% CI 1.04-2.43) and 1.92 (95% CI 0.54-6.81), respectively, among males. Perchloroethylene (PCE) was associated with incidence of non-Burkitt's high-grade NHL among females, but collinearity with TCE made it difficult to assess relative influences. The results suggest a link between TCE/PCE and leukemia/ NHL incidence. However, the conclusions are limited by potential misclassification of exposure due to lack of individual information on long-term residence, water consumption, and inhalation of volatilized compounds.

    Background Previous epidemiologic findings suggest an association between exposure to trichloroethylene (TCE), a chlorinated solvent primarily used for vapor degreasing of metal parts, and non-Hodgkin lymphoma (NHL). Objectives We investigated the association between occupational TCE exposure and NHL within a population-based case–control study using detailed exposure assessment methods. Methods Cases (n = 1,189; 76% participation rate) and controls (n = 982; 52% participation rate) provided information on their occupational histories and, for selected occupations, on possible workplace exposure to TCE using job-specific interview modules. An industrial hygienist assessed potential TCE exposure based on this information and a review of the TCE industrial hygiene literature. We computed odds ratios (ORs) and 95% confidence intervals (CIs) relating NHL and different metrics of estimated TCE exposure, categorized using tertiles among exposed controls, with unexposed subjects as the reference group. Results We observed associations with NHL for the highest tertiles of estimated average weekly exposure (23 exposed cases; OR = 2.5; 95% CI, 1.1–6.1) and cumulative exposure (24 exposed cases; OR = 2.3; 95% CI, 1.0–5.0) to TCE. Tests for trend with these metrics surpassed or approached statistical significance (p-value for trend = 0.02 and 0.08, respectively); however, we did not observe dose–response relationships across the exposure levels. Overall, neither duration nor intensity of exposure was associated with NHL, although we observed an association with the lowest tertile of exposure duration (OR = 2.1; 95% CI, 1.0–4.7). Conclusions Our findings offer additional support for an association between high levels of exposure to TCE and increased risk of NHL. However, we cannot rule out the possibility of confounding from other chlorinated solvents used for vapor degreasing and note that our exposure assessment methods have not been validated.

    Objectives Benzene is a widely recognised cause of leukaemia but its association with non-Hodgkin’s lymphoma (NHL) is less well established. The goal of this project is to review the current published literature on this association. Methods We performed a meta-analysis of cohort and case-control studies of benzene exposure and NHL and a meta-analysis of NHL and refinery work, a potential source of benzene exposure. Results In 22 studies of benzene exposure, the summary relative risk for NHL was 1.22 (95% CI 1.02 to 1.47; one-sided p value = 0.01). When studies that likely included unexposed subjects in the “exposed” group were excluded, the summary relative risk increased to 1.49 (95% CI 1.12 to 1.97, n = 13), and when studies based solely on self-reported work history were excluded, the relative risk rose to 2.12 (95% CI 1.11 to 4.02, n = 6). In refinery workers, the summary relative risk for NHL in all 21 studies was 1.21 (95% CI 1.00 to 1.46; p = 0.02). When adjusted for the healthy worker effect, this relative risk estimate increased to 1.42 (95% CI 1.19 to 1.69). Conclusions The finding of elevated relative risks in studies of both benzene exposure and refinery work provides further evidence that benzene exposure causes NHL. In addition, the finding of increased relative risks after removing studies that included unexposed or lesser exposed workers in “exposed” cohorts, and increased relative risk estimates after adjusting for the healthy worker effect, suggest that effects of benzene on NHL might be missed in occupational studies if these biases are not accounted for.

    Non-Hodgkin lymphoma (NHL) is a frequent cancer and incidence rates have increased markedly during the second half of the 20th century; however, the few established risk factors cannot explain this rise and still little is known about the aetiology of NHL. Spatial analyses have been applied in an attempt to identify environmental risk factors, but most studies do not take human mobility into account. The aim of this study was to identify clustering of NHL in space and time in Denmark, using 33 years of residential addresses. We utilised the nation-wide Danish registers and unique personal identification number that all Danish citizens have to conduct a register-based case-control study of 3210 NHL cases and two independent control groups of 3210 each. Cases were identified in the Danish Cancer Registry and controls were matched by age and sex and randomly selected from the Civil Registration System. Residential addresses of cases and controls from 1971 to 2003 were collected from the Civil Registration System and geocoded. Data on pervious hospital diagnoses and operations were obtained from the National Patient Register. We applied the methods of the newly developed Q-statistics to identify space-time clustering of NHL. All analyses were conducted with each of the two control groups, and we adjusted for previous history of autoimmune disease, HIV/AIDS or organ transplantation. Some areas with statistically significant clustering were identified; however, results were not consistent across the two control groups; thus we interpret the results as chance findings. We found no evidence for clustering of NHL in space and time using 33 years of residential histories, suggesting that if the rise in incidence of NHL is a result of risk factors that vary across space and time, the spatio-temporal variation of such factors in Denmark is too small to be detected with the applied method.

    58-year old Caucasian woman was diagnosed with sarcoidosis. Low immunoglobulin levels were found and common variable immunodeficiency (CVID) was diagnosed 1year later. Laboratory tests and clinical course at this time revealed thrombotic microangiopathy (TMA). Therapeutic plasma exchange was started and her clinical status and laboratory parameters improved. According to CVID she received human immunoglobulin intravenously. Four months later we noticed swelling of the parotid glands and generalized lymphadenopathy. Histology of cervical lymph node confirmed large B-cell non-Hodgkin lymphoma (B-cell NHL). To the best of our knowledge, TMA complicating the course of sarcoidosis, CVID and B-cell NHL has never been reported. PMID:23619325

    Cogan’s syndrome is a rare disorder characterized by ocular and audiovestibular manifestations in its typical form and caries a wide variety of atypical manifestations. It is considered as an autoimmune disease. We present the first case in the literature of a 67 year old woman with the development of low grade non-Hodgkin lymphoma (NHL) in the mastoid bone in a pre-existing history of atypical Cogan’s syndrome. The anatomical development of NHL was to a “target” organ of Cogan’s syndrome, which is the inner ear. PMID:26257951

    2014-01-01

    Background Occult HBV infection (OBI) is defined by the persistence of HBV in the liver without serum HBsAg and HBVDNA. It represents a life-threatening event during immunosuppressive chemotherapies. An OBI occurs in approximately 18% of HBcAb + patients. International guidelines suggest surveillance for HBV markers in immunosuppressed patients. In Non-Hodgkin Lymphoma (NHL), the prevalence of OBI reactivation remains to be established. Methods In order to determine the prevalence of occult HBV reactivation in a large cohort of patients during chemotherapy for NHL, we analysed 498 NHL patients in a centre of Southern Italy. We evaluated HBV markers, NHL type, treatment type and occurrence of HBV reactivation. Results Forty % of patients were treated with monoclonal antibodies and 60.3% without. Ninety-six patients were HBcAb+, HBsAg-. HBV reactivation occurred in ten subjects of this subgroup. All of them were successfully treated with Lamivudine. None of the patients experienced liver-related death. The prevalence of OBI reactivation was of 10.42% in HBcAb + HBsAb- patients. This event occurred in 50% of patients treated with mild immunosuppressive therapies. Each reactivation was treated with Lamivudine. Discussion This report suggests that a strict surveillance is important and cost-effective in HBcAb + HBsAg- NHL patients treated with mild immunosuppressive therapies, in order to detect an occult HBV reactivation.

    The toxicity of low-dose total body irradiation (LTBI), the prognostic factors related to survival and relapse-free survival, and the efficacy of treatment given for relapse after LTBI were analyzed in 68 patients with non-Hodgkin lymphoma (NHL) treated at the Rotterdamsch Radiotherapeutisch Instituut. All patients received LTBI between 1973 and 1979. The patient material was heterogeneous with respect to malignancy grade, stage, age, and therapy given before or after LTBI; the unifying principle was that all patients received LTBI and had symptomatic NHL. Analysis of prognostic variables with Cox's model revealed grade (p less than 0.001) and age (p = 0.004) as predictors for survival and grade (p less than 0.001) and dose of LTBI (p = 0.056) as predictors for relapse-free survival after LTBI. No subjective toxicity was observed during or after LTBI treatment. Hematologic toxicity was dose-limiting and was increased if patients had received cytotoxic treatment before LTBI. LTBI-related hematologic toxicity was lower in patients with low-grade NHL than in those with intermediate or high-grade NHL, was limited in time, and recovered in all patients. Patients relapsing after LTBI received a variety of therapies. Response rates were high, but of short duration, especially in intermediate or high-grade NHL. Duration of response was progressively shorter after multiple relapses.

    NHL (NDR1/HIN1-like) genes play crucial roles in pathogen induced plant responses to biotic stress. Here, we report the possible function of NHL6 in plant response to abscisic acid (ABA) and abiotic stress. NHL6 was highly expressed in non-germinated seeds, and its expression was strongly induced by ABA and multiple abiotic stress signals. Loss-of-function of NHL6 decreased sensitivity to ABA in the early developmental stages including seed germination and post-germination seedling growth of the nhl6 mutants. However, overexpression of NHL6 increased sensitivity to ABA, salt and osmotic stress of the transgenic plants. Further studies indicated that the increased sensitivity in the 35S::NHL6 overexpressing plants could be a result of both ABA hypersensitivity and increased endogenous ABA accumulation under the stress conditions. It was also seen that the ABA-responsive element binding factors AREB1, AREB2 and ABF3 could regulate NHL6 expression at transcriptional level. Our results indicate that NHL6 plays an important role in the abiotic stresses-induced ABA signaling and biosynthesis, particularly during seed germination and early seedling development in Arabidopsis.

    Background The proper histopathological characterization of malignant lymphomas requires the use of immunohistochemistry along with other molecular pathology techniques. Materials and Methods Malignant lymphomas histologically diagnosed in our hospital were reclassified according to the WHO scheme using immunohistochemistry while in-situ hybridization was performed for the detection of Epstein-Barr virus encoded RNA. Results There were 83 cases of lymphoma. The male to female ratio was 1.9:1 while the overall mean age was 41.7 years. Non-Hodgkin lymphomas (NHL) constituted about 79.5% of cases. The majority of cases (98.8%) were B-cell lymphomas. Nine subtypes of lymphomas were identified with diffuse large B-cell lymphomas (56.4% of which were of the germinal centre type) constituting the largest group (47.0%). Intermediate and high grade subtypes were more common. The majority of cases (72.3%) were nodal lymphomas with cervical lymph node being the commonest site (48.2%). Only classical Hodgkin lymphoma (HL) (20.5%) was seen of which the mixed cellularity subtype was the most common. Epstein Barr virus (EBV) encoded ribonucleic acid was detected in 7 cases (8.4%) including 4 cases of HL, 2 cases of Burkitt lymphoma and the only case of plasmablastic lymphoma. About five cases were reclassified as non-lymphoid malignant lesions. Conclusion Immunohistochemistry is vital to the proper classification of lymphomas even in a resource poor environment. Although nine subtypes of lymphomas were identified, diffuse large B-cell lymphomas formed the largest single group. Epstein-Barr virus probably plays an important role in lymphomatogenesis in this environment. A larger multicentre study is required to prove this. PMID:26266128

    Hepatitis C Virus (HCV) infection is associated with the B-cell non-Hodgkin lymphomas (NHL), preferentially marginal zone lymphomas (MZL) and diffuse large B-cell lymphomas (DLBCL). While chronic antigenic stimulation is a main determinant of lymphomagenesis in marginal zone lymphomas (MZL), a putative role of HCV infection of B-cells is supported by in vitro studies. We performed a pathological study within the "ANRS HC-13 LymphoC" observational study focusing on in situ expression of the oncogenic HCV non structural 3 (NS3) protein. Lympho-C study enrolled 116 HCV-positive patients with B-NHL of which 86 histological samples were collected for centralized review. Main histological subtypes were DLBCL (36%) and MZL (34%). Almost half of DLBCL (12/26) were transformed from underlying small B-cell lymphomas. NS3 immunostaining was found positive in 17 of 37 tested samples (46%). There was a striking association between NS3 detection and presence of high grade lymphoma features: 12 out of 14 DLBCL were NS3+ compared to only 4 out of 14 MZL (p = 0.006). Moreover, 2 among the 4 NS3+ MZL were enriched in large cells. Remarkably, this study supports a new mechanism of transformation with a direct oncogenic role of HCV proteins in the occurrence of high-grade B lymphomas. PMID:27257992

    Outcomes in pediatric B-Non-Hodgkin Lymphoma (B NHL) have improved with intensive chemotherapy protocols, with long-term survival now over 80%. However, long-term adverse effects of therapy and poor outcomes for patients who relapse remain challenges. In this study, we aimed to evaluate the potential risks and benefits of routine relapse surveillance imaging after the completion of therapy. We reviewed 44 B NHL patients diagnosed and treated at Texas Children's Cancer Center in the period between 2000 to 2011. All cross-sectional diagnostic imaging examinations performed for disease assessment after completion of chemotherapy were reviewed and cumulative radiation dosage from these examinations and the frequency of relapse detection by these examinations were recorded. Only 3 patients of the 44 relapsed (6.8%), though none of the relapses were initially diagnosed by computed tomography (CT) or fludeoxyglucose positron emission tomography (FDG-PET) scans. Median effective dose of ionizing radiation per patient was 40.3 mSv with an average of 49.1 mSv (range 0-276 mSv). This single-institution study highlights the low relapse rate in pediatric B-NHL with complete response at the end of therapy, the low sensitivity of early detection of relapse with surveillance CT or FDG-PET imaging, and the costs and potential increased risk of secondary malignancies from cumulative radiation exposure from surveillance imaging. We propose that routine surveillance CT or FDG-PET scans for these patients may not be necessary. PMID:24087880

    Many epidemiologic studies have explored the association between dairy product consumption and the risk of non-Hodgkin lymphoma (NHL), but the results remain controversial. A literature search was performed in PubMed, Web of Science and Embase for relevant articles published up to October 2015. Pooled relative risks (RRs) with 95% confidence intervals (CIs) were calculated with a random-effects model. The dose-response relationship was assessed by restricted cubic spline. A total of 16 articles were eligible for this meta-analysis. The pooled RRs (95% CIs) of NHL for the highest vs. lowest category of the consumption of total dairy product, milk, butter, cheese, ice cream and yogurt were 1.20 (1.02, 1.42), 1.41 (1.08, 1.84), 1.31 (1.04, 1.65), 1.14 (0.96, 1.34), 1.57 (1.11, 2.20) and 0.78 (0.54, 1.12), respectively. In subgroup analyses, the positive association between total dairy product consumption and the risk of NHL was found among case-control studies (RR = 1.41, 95% CI: 1.17–1.70) but not among cohort studies (RR = 1.02, 95% CI: 0.88–1.17). The pooled RRs (95% CIs) of NHL were 1.21 (1.01, 1.46) for milk consumption in studies conducted in North America, and 1.24 (1.09, 1.40) for cheese consumption in studies that adopted validated food frequency questionnaires. In further analysis of NHL subtypes, we found statistically significant associations between the consumption of total dairy product (RR = 1.73, 95% CI: 1.22–2.45) and milk (RR = 1.49, 95% CI: 1.08–2.06) and the risk of diffuse large B-cell lymphoma. The dose-response analysis suggested that the risk of NHL increased by 5% (1.05 (1.00–1.10)) and 6% (1.06 (0.99–1.13)) for each 200 g/day increment of total dairy product and milk consumption, respectively. This meta-analysis suggested that dairy product consumption, but not yogurt, may increase the risk of NHL. More prospective cohort studies that investigate specific types of dairy product consumption are needed to confirm this conclusion

    Non-Hodgkin lymphoma (NHL) is one of the most common hematologic malignancies among adults for which the chimeric monoclonal anti-CD20 antibody (Ab) rituximab (RTX) is used as first-line therapy. As RTX itself is not directly cytotoxic but relies on host immune effector mechanisms or chemotherapeutic agents to attack target cells, its therapeutic capacity may become limited when host effector mechanisms are compromised. Currently, refractory disease and relapse with NHL are still common, highlighting the need for novel anti-CD20 antibody strategies with superior therapeutic efficacy over current protocols. We hypothesized that making RTX directly cytotoxic might improve the therapeutic efficacy. Graphene oxide (GO) has recently emerged as a highly attractive nanomaterial for biomedical applications; and several studies have reported cytotoxic effect of GO on benign and malignant cells in vitro. Herein, we report that RTX can be stably associated with GO, and that GO-associated RTX (RTX/GO) demonstrates remarkably high avidity for CD20. Binding of GO-associated RTX to CD20-positive lymphoma cells induces CD20 capping and target cell death through an actin dependent mechanism. In vivo, GO-associated RTX, but not free RTX, quickly eliminates high-grade lymphomas in the absence of host effector mechanisms in a xenograft lymphoma mouse model. Our findings represent the first demonstration of using GO-associated antibody as effective cytotoxic therapy for human B cell malignancies in the absence of chemotherapy, and these findings could have important clinical implications.

    The use of effective combination chemotherapy for all stages and subtypes of non-Hodgkin"s lymphoma (NHL) in children has resulted in a striking improvement in cure rates. Event-free survival now ranges from 70% to 90%, depending on the stage of disease and the NHL subtype. Risk-adapted therapy has resulted in a dramatic improvement in outcome for high-risk patients, at the cost of significantly increased short-term toxicity, and a reduction of therapy and toxicity for the lower-risk patient, while maintaining the excellent cure rate. Successful risk allocation of patients is dependent on the identification and continual validation of prognostic factors. The specific treatment protocol is the single most important factor predicting outcome today. Traditional prognostic factors such as stage and tumor burden are useful in selecting the intensity and length of therapy, rather than as a major indicator of likelihood of survival. In order to further improve cure rates and decrease toxicity, new biologic prognosticators need to be found and validated. Some promising avenues for study appear to be the presence or absence of adhesion molecules and of aberrant proteins that are specific to subtypes of lymphomas, such as soluble CD30 and anaplastic lymphoma kinase (ALK), the molecular classification of lymphomas on the basis of gene expression, and the evaluation of biologic markers for measuring early response to therapy.

    We studied the outcome of allogeneic transplantation after lower-intensity conditioning regimens (reduced-intensity [RIC] and non-myeloablative [NST]) in non-Hodgkin lymphoma (NHL) relapsing after autologous transplantation. Non-relapse mortality (NRM), lymphoma progression/relapse, progression-free survival (PFS) and overall survival (OS) were analyzed in 263 NHL patients. All had relapsed after a prior autologous transplant and then received allogeneic transplantation from related (n = 26) or unrelated donors (n= 237) after RIC (n = 128) or NST (n = 135), and were reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) between 1996 and 2006. Median follow-up of survivors was 68 months (range, 3–111). Three-year NRM was 44% (95% CI, 37%–50%). Lymphoma progression/relapse at three years was 35% (95% CI, 29%–41%). Three-year probabilities of PFS and OS were 21% (95% CI, 16%–27%) and 32% (95% CI, 27%–38%) respectively. Superior performance score, longer interval between transplants, total-body irradiation-based conditioning regimen and lymphoma remission at transplantation correlated with improved PFS. Allogeneic transplantation after lower-intensity conditioning is associated with significant NRM, but can result in long-term PFS. We describe a quantitative risk model based on pretransplant risk factors in order to identify those likely to benefit from this approach. PMID:22198543

    We analyzed the outcomes of 283 patients receiving unrelated donor allogeneic hematopoietic cell transplantation for non-Hodgkin lymphoma (NHL) facilitated by the Center for International Blood & Marrow Transplant Research /National Marrow Donor Program (CIBMTR/NMDP) between 1991 and 2004. All patients received myeloablative conditioning regimens. The median follow-up of survivors is 5 years. Seventy-three (26%) patients are alive. The day 100 probability of death from all causes is estimated at 39%. The cumulative incidence of developing grade III-IV acute graft-versus-host disease (GVHD) at day 100 is 25%. The estimated five-year survival and failure free survival are 24% (95% CI; 19–30) and 22% (95% CI; 17–28) respectively. Factors adversely associated with overall survival included increasing age, decreased performance status, and refractory disease. Follicular lymphoma and Peripheral T-cell lymphoma had improved survival compared to aggressive B-cell lymphomas. Factors adversely associated with progression free-survival included performance status, histology and disease status at transplant. Long-term failure-free survival is possible following unrelated donor transplantation for NHL, although early mortality was high in this large cohort. PMID:19361747

    Hematopoietic stem cell transplant (HSCT) is recommended for pediatric patients with relapsed/refractory lymphoma even though the evidence for this is limited. We retrospectively reviewed records of 57 patients (29 Hodgkin lymphoma [HL], 28 non-Hodgkin lymphoma [NHL]) who underwent HSCT between 1995 and 2012. All demonstrated chemoresponsiveness prior to HSCT and 44 patients had a complete response. All underwent myeloablative conditioning, 38 chemotherapy-based and 19 total body irradiation-based. Forty-one patients received autologous and 16 allogeneic HSCT. Twelve (21%) died within 100 days post-HSCT, and 25 patients relapsed at a median of 1.6 months post-HSCT. Three patients developed second malignant neoplasms. Five-year overall survival (OS) was 50.5% and event-free survival (EFS) was 43.4%. Outcomes for HL were significantly better than those for NHL (OS 61.9% vs. 38.7% [p = 0.005] and EFS 60.4% vs. 26% [p = 0.008]). In summary, approximately half of all pediatric patients with lymphoma who failed first-line therapy and demonstrated chemosensitivity to second-line therapy can be salvaged with HSCT. PMID:25139691

Owing to the rarity, there is a lack of consensus about underlying mechanism as well as optimal treatment strategy, and diagnosing both malignancies together without a delay remains a complex clinical challenge. We report a case of synchronous presentation of IDC and MCL in a 67-year-old female patient whose MCL diagnosis was delayed due to a misinterpretation of her B symptoms as postmenopausal, with a review of the literature on concurrently occurring breast carcinoma and NHL.

    Lenalidomide, an immunomodulatory drug that the US Food and Drug Administration (FDA) approved for the treatment of multiple myeloma, 5q- myelodysplasia and mantle-cell lymphoma (MCL), has encouraging efficacy in other B-cell malignancies. Its unique mechanism of action is in part due to altering the tumor microenvironment and potentiating the activity of T and natural-killer (NK) cells. Impressive clinical activity and excellent tolerability allows broad applicability. Lenalidomide has been used in a wide range of B-cell malignancies for years, but in 2013, the FDA marked its approval as a single agent only in relapsed/refractory mantle-cell lymphoma. Perhaps most impressive is the efficacy of lenalidomide when combined with monoclonal antibodies. Impressive efficacy and toxicity profiles with the combination of lenalidomide and rituximab in B-cell lymphomas in both the upfront and relapsed/refractory setting may allow a shift in our current treatment paradigm in both indolent and aggressive non-Hodgkin lymphoma (NHL). This review will summarize the current data in the relapsed/refractory and front-line setting of NHL with single-agent lenalidomide as well as its use in combination with other agents. PMID:27493711

    Non-Hodgkin's lymphoma (NHL), a disease which may involve the spine, is frequently associated with advanced disease. Radiculopathy caused by spinal root compression as the initial presentation in patients with NHL is very rare and thought to occur in less than 5% of cases. A 69-year-old woman complained of a history of low back pain with right sciatica for 1 month prior to admission. Computed tomography and magnetic resonance imaging of the lumbar spine showed a dumbbell-shape epidural mass lesion extending from L2 to L3, which was suggestive of a neurogenic tumor. After paraspinal approach and L2 lower half partial hemilaminectomy, total excision of the tumor was achieved, followed by rapid improvement of back pain and radiating pain. The lesion was confirmed to be Burkitt's lymphoma by histopathological examination. We then checked whole-body PET-CT, which showed multifocal malignant lesions in the intestine, liver, bone and left supraclavicular lymph node. Although a rare situation, Burkitt's lymphoma should be considered in the differential diagnosis for patients presenting with back and lumbar radicular pain without a prior history of malignancy. Burkitt's lymphoma could be the cause of dumbbell-shape spinal tumor. PMID:26512290

    Radioimmunotherapy, an emerging treatment option for certain patients with non-Hodgkin's lymphoma (NHL), enables the targeting of cytotoxic radiation to tumor cells with minimal irradiation of normal cells. Yttrium 90 ibritumomab tiuxetan (Zevalin; Biogen Idec Inc, Cambridge, MA) was approved in February 2002 for the treatment of patients with relapsed or refractory low-grade, follicular, or transformed B-cell NHL, including patients with rituximab-refractory NHL. Yttrium 90 ibritumomab tiuxetan is an effective treatment with a consistent overall response rate of 73% to 83%. It has a good safety profile and is generally well tolerated in the indicated population. The results of clinical trials show that (90)Y ibritumomab tiuxetan can be used effectively and safely in many patients with NHL, including those with mild thrombocytopenia and those with disease that is refractory to rituximab, without the adverse events associated with conventional chemotherapy and external beam radiation therapy. The use of (90)Y ibritumomab tiuxetan does not preclude subsequent therapy with other conventional treatment options. PMID:14710398

    Background and objectives: Numerous studies have focused on the role of survivin in non-Hodgkin’s lymphomas (NHLs), but evidence regarding the prognostic value of survivin with respect to overall survival (OS) in NHL remains controversial. The aim of this study is to gain a better insight about the direct relationship between survivin expression and patients’ survival statuses. Materials and methods: Relevant publications addressing the association between survivin expression and OS in NHL patients were selected from PubMed, Embase, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure Database (CNKI), China Science and Technology Journal Database (VIP), Wanfang Database and the Cochrane library. Studies were pooled and summary hazard ratios (HR) were calculated. Sensitivity analyses and publication bias were also conducted. Statistical analysis was performed by STATA 12.0 software. Results: 12 studies met the inclusion criteria. Combined HRs suggested that survivin overexpression had an unfavorable impact on NHL patients’ survival (HR=1.55, 95% CI=1.12-2.13, P=0.008). Subgroup analyses according to the studies categorized by histological type, ethnicity, cutoff scores and follow-up period were also conducted, and all the above analyses supported the stability of the prognostic role of survivin. Conclusion: Our findings suggest that survivin high expression might be a poor prognostic factor for patients with NHL. However, further large scale studies are needed to confirm these findings.

    Growing evidence indicates that exposure to organochlorine pesticides (OCPs) could increase non-Hodgkin lymphoma (NHL) risk. However, results from epidemiological studies investigating this association remain controversial. We thus conducted a meta-analysis to quantitatively evaluate the association between OCP exposure and NHL risk. Relevant publications were searched in PubMed, Web of Science, and Embase and identified according to the inclusion criteria. Thirteen studies (6 nested case-control, 1 case-cohort, and 6 case-control) were selected for this meta-analysis. We used odds ratios (ORs) with 95% confidence intervals (CIs) to estimate the relationship between OCPs exposure and NHL risk. The summary OR for included studies was 1.40 (95% CI 1.27 to 1.56). No overall significant heterogeneity in the OR was observed (Ph = 0.253, I2 = 12.6%). Furthermore, OR estimates in subgroup analyses were discussed, and strong associations were observed for dichlorodiphenyldichloroethylene (DDE, OR = 1.38, 95% CI 1.14 to 1.66), hexachlorocyclohexane (HCH, OR = 1.42, 95% CI 1.08 to 1.87), chlordane (OR = 1.93, 95% CI 1.51 to 2.48), and hexachlorobenzene (HCB, OR = 1.54, 95% CI 1.20 to 1.99). This meta-analysis had suggested that total OCPs of interest was significantly positively associated with NHL risk. PMID:27185567

    2016-05-01

    Non-Hodgkin lymphoma (NHL) is the third most common malignancy in children, adolescents and young adults (CAYA). NHL is a diverse set of diseases that arise at key regulatory checkpoints during B or T cell development in the bone marrow, germinal centre or thymus. While advances in the use of conventional cytotoxic agents have led to dramatic improvements in survival, these cures are associated with significant acute and long-term toxicities. Moreover, the prognosis for CAYA patients with relapsed or refractory NHL remains dismal, with the vast majority dying of their disease. Thanks to a large number of candidate-based biological studies, together with large-scale sequencing efforts, there has been an explosion of knowledge regarding the molecular pathophysiology of B- and T-NHL. This has ushered development of a flurry of novel therapeutic approaches that may simultaneously provide new hope for relapsed patients and an opportunity to reduce the therapeutic burden in newly diagnosed CAYA. Here we review a selection of the most promising new therapeutic approaches to these diseases. While the vast majority of these agents are untested in children, on-going work from many cooperative groups will soon explore their use in paediatric disease, in hope of further improving outcomes while maximizing quality of life.

Furthermore, OR estimates in subgroup analyses were discussed, and strong associations were observed for dichlorodiphenyldichloroethylene (DDE, OR = 1.38, 95% CI 1.14 to 1.66), hexachlorocyclohexane (HCH, OR = 1.42, 95% CI 1.08 to 1.87), chlordane (OR = 1.93, 95% CI 1.51 to 2.48), and hexachlorobenzene (HCB, OR = 1.54, 95% CI 1.20 to 1.99). This meta-analysis had suggested that total OCPs of interest was significantly positively associated with NHL risk. PMID:27185567

    We conducted a preliminarily study on the clinical characteristics of chronic lung injury (CLI) in patients with non-Hodgkin lymphoma (NHL) after CHOP chemotherapy and observed the effects of this injury on CHOP treatment efficacy. Sixty patients who were diagnosed as NHL and received CHOP chemotherapy in hospital were enrolled for this clinical trial. CLI was assessed by clinical symptoms and computed tomography (CT) scan conducted before and after chemotherapy. The effect of CLI on the efficacy of CHOP chemotherapy in patients with NHL was evaluated by comparing treatment response and recurrence rate to patients with no signs of lung injury. Our CT scans revealed multiple signs of CLI in 35 patients (56.67 %), such as pulmonary diffuse, limited infiltration shadow or ground glass-like changes. Among them, 23 patients (38.33 %) showed bilateral diffuse lung injury and 12 (20.00 %) showed topical lung injury. Most patients suffering from 6 to 12 months delayed recurrence exhibited signs of CLI. The inflammatory response of CLI may increase the risk of disease progression and recurrence. Therefore, early diagnosis and intervention, which play a positive role in the clinical treatment and the long-term efficacy, are critical for patients with NHL. PMID:25201066

    Purpose: The aim of this study was to review advances in radioimmunotherapy (RIT) for non-Hodgkin's lymphoma (NHL) and to discuss the role of Radiation oncologist in administering this important new form of biologically targeted radiotherapy. Methods and Materials: A review of articles and abstracts on the clinical efficacy, safety, and radiation safety of yttrium Y 90 ({sup 9}Y) ibritumomab tiuxetan (Zevalin) and iodine I 131 tositumomab (Bexxar) was performed. Results: The clinical efficacy of RIT in NHL has been shown in numerous clinical trials of {sup 9}Y ibritumomab tiuxetan and {sup 131}I tositumomab. Both agents have produced significant responses in patients with low-grade, follicular, or transformed NHL, including patients with disease that had not responded or had responded poorly to previous chemotherapy or immunotherapy. Reversible toxicities such as neutropenia, thrombocytopenia, and anemia are the most common adverse events with both agents. Conclusions: Radioimmunotherapy is safe and effective in many patients with B-cell NHL. {sup 9}Y ibritumomab tiuxetan and {sup 131}I tositumomab can produce clinically meaningful and durable responses even in patients in whom chemotherapy has failed. Treatment with RIT requires a multispecialty approach and close communication between Radiation oncologist and other members of the treatment team. Radiation oncologist plays an important role in treating patients with RIT and monitoring them for responses and adverse events after treatment.

    Primary pulmonary non-Hodgkin's lymphoma (NHL) is very rare. It represents less than 1% of all NHL, and 0.5-1% of all primary pulmonary malignancies. Almost all cases of primary pulmonary NHL originate from B-cell lineage. We present a case of a 53-year-old man with primary extranodal NK/T-cell lymphoma of the bronchus and lung, presented progressive dyspnea caused by right lower lung consolidation, and pleural effusion. Initial chest computed tomography suggested advanced lung cancer. Bronchofiberscopy showed a polypoid tumor on which a biopsy was performed. Histologically, the diffusely infiltrative atypical cells were positive for cytoplasmic CD3, CD56, granzyme B, and negative for cytokeratin, CD20 immunostains, suggesting NK/T cell lineages. In situ hybridization for Epstein-Barr virus encoded ribonucleic acid (EBER) was positive. Herein, we discuss the clinicopathological features of this case and review the literature on primary extranodal NK/T-cell lymphoma of the lung. Compared with other patients, who died after the first cycle of chemotherapy and/or within three months, our patient had longer survival under aggressive chemotherapy and auto-peripheral blood stem cell transplantation.

    2013-01-01

    Background Residence near municipal solid waste incinerators, a major historical source of dioxin emissions, has been associated with increased risk of non-Hodgkin lymphoma (NHL) in European studies. The aim of our study was to evaluate residence near industrial combustion facilities and estimates of dioxin emissions in relation to NHL risk in the United States. Methods We conducted a population-based case–control study of NHL (1998–2000) in four National Cancer Institute-Surveillance Epidemiology and End Results centers (Detroit, Iowa, Los Angeles, Seattle). Residential histories 15 years before diagnosis (similar date for controls) were linked to an Environmental Protection Agency database of dioxin-emitting facilities for 969 cases and 749 controls. We evaluated proximity (3 and 5 km) to 10 facility types that accounted for >85% of U.S. emissions and a distance-weighted average emission index (AEI [ng toxic equivalency quotient (TEQ)/year]). Results Proximity to any dioxin-emitting facility was not associated with NHL risk (3 km OR = 1.0, 95% CI 0.8-1.3). Risk was elevated for residence near cement kilns (5 km OR = 1.7, 95% CI 0.8-3.3; 3 km OR = 3.8, 95% CI 1.1-14.0) and reduced for residence near municipal solid waste incinerators (5 km OR = 0.5, 95% CI 0.3-0.9; 3 km OR = 0.3, 95% CI 0.1-1.4). The AEI was not associated with risk of NHL overall. Risk for marginal zone lymphoma was increased for the highest versus lowest quartile (5 km OR = 2.6, 95% CI 1.0-6.8; 3 km OR = 3.0, 95% CI 1.1-8.3). Conclusions Overall, we found no association with residential exposure to dioxins and NHL risk. However, findings for high emissions and marginal zone lymphoma and for specific facility types and all NHL provide some evidence of an association and deserve future study. PMID:23433489

    Abstract Hepatitis B virus (HBV) infection remains an endemic disease in most parts of the world despite available prophylactic vaccines. Non-Hodgkin’s lymphoma is the most common hematological malignancy, and certain patients undergoing therapy are at increased risk of HBV reactivation. Rituximab, a monoclonal antibody, is well studied in HBV reactivation, but newer agents have been implicated as well. Here, we review novel agents suspected in HBV reactivation and effective strategies to prevent HBV reactivation. Fifteen years of literature were reviewed in order to better understand the reactivation rates of hepatitis B in patients with non-Hodgkin’s lymphoma. Anti-CD20 antibodies continue to be the main medications that can lead to HBV reactivation, and HBV reactivation rates have decreased with increased awareness. HBV reactivation is uncommon when using other novel agents. Entecavir and lamivudine remain the agents of choice to prevent HBV reactivation in high risk patients. In conclusion, the immunosuppressive effect of NHL and its therapy provide a pathway for HBV reactivation, especially in patients treated with anti-CD20 antibody. Since many HBV positive patients are often excluded from clinical trials of novel agents in NHL, more aggressive post-market surveillance of new agents, well-designed best practice advisories, and timely case reports are needed to reduce the incidence of HBV reactivation. Lastly, large prospective investigations coupled with well-utilized best practice advisories need to be conducted to understand the impact of more potent novel NHL therapy on HBV reactivation.

    Rituximab pharmacokinetics are affected by gender, age and weight and can affect outcomes in aggressive B cell lymphoma. Less is known about the pharmacokinetics of rituximab in indolent B cell lymphoma (iNHL). We analysed the effects of gender, age, weight and body surface area on the outcomes of 303 patients treated with first line rituximab-based regimens for iNHL. The patients were divided into 3 treatment cohorts: rituximab only, rituximab + chemotherapy (R-CTX) and R-CTX followed by rituximab maintenance; furthermore, each cohort was subdivided as follicular (FL) or non-FL, based on histology. Older males and patients with higher weight had worse outcomes when treated with R-CTX, probably due to faster rituximab clearance. Our results concur with studies of R-CTX for DLBCL. As this effect was not observed in patients treated with rituximab alone or R-CTX followed by rituximab maintenance, we hypothesize that higher rituximab levels reached with weekly rituximab and/or prolonged exposure achieved with maintenance therapy exceed the therapeutic threshold, even with faster clearance, which nullifies the negative effect of higher weight and male gender. In conclusion, under current practices, a subset of patients with iNHL, i.e., FL treated with R-CTX, may be sub-optimally dosed with rituximab. PMID:27136331

    Systemic AL amyloidosis (AL) is a disorder in which light chains form fibrillar deposits, leading to organ dysfunction and death. Rarely, AL has been associated with non-Hodgkin's lymphoma (NHL), although this association has not been well characterized. We report a series of six patients with AL associated with NHL, primarily lymphoplasmacytic lymphoma. Organ involvement was variable, with frequent bulky lymphadenopathy and visceral cavity deposits, but no cardiac involvement. Positron emission tomography scans were negative. Bone marrow and lymph node biopsies showed a mixed population of CD20+ lymphoid and CD138+ plasma cells. Serum free light chains were elevated, and correlated with response to therapy. Immunoglobulin light chain variable region (Ig VL) germline gene use was typical for AL, reflecting previously observed correlations between germline gene use and organ tropism. Five patients received rituximab-based therapies with two responses. Two patients underwent autologous stem cell transplantation with one complete haematological response. Four patients survive at 10-132 months from diagnosis. AL with NHL has distinctive clinical features but employs the same Ig VL gene repertoire as AL with clonal plasma cell dyscrasias. Serial serum free light chain levels are useful for tracking response to therapy. Treatments aimed at both lymphoid and plasma cell components appear warranted. PMID:14717777

    Indolent non-Hodgkin's lymphoma (iNHL) describes a group of B-cell lymphomas with a long median survival and a relapsing-remitting clinical course. Although existing treatments are initially effective, patients often relapse, demonstrating decreasing efficacy with successive treatment courses. Alternative treatments are needed. PI3Kδ plays an essential, non-redundant role in B-cell receptor signaling critical to the pathogenesis of iNHL. It is expressed predominantly in hematopoietic cells, making PI3Kδ an attractive therapeutic target. Idelalisib is an oral PI3Kδ inhibitor approved in 2014 in the USA and the EU as monotherapy in relapsed follicular lymphoma or relapsed small lymphocytic lymphoma previously treated with two or more prior systemic therapies, or as part of combination therapy with rituximab in patients with chronic lymphocytic leukemia, for whom rituximab monotherapy would be considered appropriate due to the presence of comorbidities. Herein, we review the available data for idelalisib, with an emphasis on relapsed/refractory B-cell iNHL. PMID:26343890

    Primary thyroid lymphomas are rare, and the majority are B-cell lymphoma. Primary Burkitt’s lymphoma (BL) of the thyroid is much less common than the other types of lymphoma. The current study presents the case of an eight-year-old male with a mass in the right lobe of the thyroid, which was detected by B-ultrasound. The patient was diagnosed with BL by immunohistochemistry, fluorescence in situ hybridization analysis of MYC (8q24) and immunoglobulin rearrangement assays. Furthermore, subsequent positron emission tomography-computed tomography scans revealed no abnormal metabolites in the left lobe of the thyroid or in other parts of the body following surgery. The patient underwent alternate R-B-NHL-BFM-90-A and R-B-NHL-BFM-90-B treatment for four cycles each following the thyroidectomy. The patient is well and remains free of disease recurrence following almost four years follow-up. The present study discusses this rare case of primary BL of the thyroid and presents a review of the literature. This case report provides evidence that the immediate diagnosis and treatment of primary Burkitt’s lymphoma of the thyroid is likely to improve patient outcome. PMID:24765169

    Background We evaluated the influence of folate pathway polymorphisms on high-dose methotrexate (HD-MTX) related toxicity in paediatric patients with T-cell non-Hodgkin lymphoma (NHL). Patients and methods In total, 30 NHL patients were genotyped for selected folate pathway polymorphisms. Results Carriers of at least one MTHFR 677T allele had significantly higher MTX area under the time-concentration curve levels at third MTX cycle (P = 0.003). These patients were also at higher odds of leucopoenia (P = 0.006) or thrombocytopenia (P = 0.041) and had higher number of different HD-MTX-related toxicity (P = 0.035) compared to patients with wild-type genotype. Conclusions Our results suggest an important role of MTHFR 677C>T polymorphism in the development of HD-MTX-related toxicity in children with NHL. PMID:25177243

    The aim of this study was to evaluate the risk of non-Hodgkin's lymphoma (NHL) in an adult population residing in an area in northern Italy exposed to industrial air pollution from a big power plant, a coke oven, 2 chemical factories, and some minor plants. The design was a population-based case-control study and information about residential history and the main risk factors for NHL was obtained interviewing 133 cases and 279 controls using a structured questionnaire. Three exposure categories (heavy, moderate, and slight) were defined on the basis of the location of the major facilities with respect to the subject residence. NHL risk was not associated either with location or duration of residence in the heavily polluted area. However, the unavoidable limitations of this study prevent us from drawing definitive conclusions. PMID:24325744

    Background Epstein-Barr virus (EBV) infection has been associated with lymphoma development. EBV latent membrane protein 1 (LMP1) is essential for EBV-mediated transformation and progression of different human cells, including lymphocytes. This meta-analysis investigated LMP1 expression with prognosis of patients with lymphoma. Methods The electronic databases of PubMed, Embase, and Chinese Biomedicine Databases were searched. There were 15 published studies available for a random effects model analysis. Quality assessment was performed using the Newcastle-Ottawa Quality Assessment Scale for cohort studies. A funnel plot was used to investigate publication bias, and sources of heterogeneity were identified by meta-regression analysis. The combined hazard ratios (HR) and their corresponding 95% confidence intervals of LMP1 expression were calculated by comparison to the overall survival. Results Overall, there was no statistical significance found between LMP1 expression and survival of lymphoma patients (HR 1.25 [95% CI, 0.92–1.68]). In subgroup analyses, LMP1 expression was associated with survival in patients with non-Hodgkin lymphoma (NHL) (HR  = 1.84, 95% CI: 1.02–3.34), but not with survival of patients with Hodgkin disease (HD) (HR  =  1.03, 95% CI: 0.74–1.44). In addition, significant heterogeneity was present and the meta-regression revealed that the outcome of analysis was mainly influenced by the cutoff value. Conclusions This meta-analysis demonstrated that LMP1 expression appears to be an unfavorable prognostic factor for overall survival of NHL patients. The data suggested that EBV infection and LMP1 expression may be an important factor for NHL development or progression. PMID:23613723

    Precursor B-cell lymphoblastic lymphoma (PBLL) is a rare subtype of childhood non-Hodgkin lymphoma (NHL). Most lymphoblastic lymphomas have a T-cell immunophenotype, but a small distinct proportion is of precursor B-cell origin. Skin and bone involvement is seen more commonly in this clinical variant. Primary cutaneous PBLL is rare. We describe an 8-year-old girl who presented with an asymptomatic nodule on the left upper arm. Histopathological features were consistent with pre-B-cell lymphoblastic lymphoma, and staging investigations excluded extracutaneous disease, resulting in a diagnosis of primary cutaneous PBLL. The child was started on induction chemotherapy, UKALL 2003 regimen B. She developed disseminated varicella zoster virus and died despite treatment. We discuss previously reported cases of primary cutaneous PBLL and their outcomes. PMID:25959984

    Every patient in every part of the world has the right to expect the best possible quality of care from health care providers. Non-Hodgkin's lymphomas (NHL) are an extremely heterogeneous group of conditions which require important decisions to be taken at many points along the treatment pathway. To get this right every time requires that high-quality standards are instituted and adhered to, so that the best possible outcome is achieved. In the past this has not always been the case because of the failure of clinicians sometimes to adhere to an optimal management plan. In 1995, the UK government commissioned an inquiry into the running of cancer services in the United Kingdom, which culminated in a series of recommendations to improve them. Subsequently, these recommendations were implemented as objectives of the NHS Cancer Plan which is the framework by which the UK government wishes to improve cancer services. Concurrently another general concept has emerged which is designed to ensure that the highest quality standards may be achieved for all patients across the whole National Health Service (NHS). This concept, termed 'clinical governance', brings together a corporate responsibility of all health care workers to deliver high quality standards, in the hope that this will translate into better long-term survival of patients with malignant disease. This chapter focuses on the issues surrounding clinical governance and how the principles of this concept relate to non-Hodgkin's lymphomas. PMID:12468407

    A 56-year-old male admitted with haematemesis and epigastric pain and severe weight loss on a background of coeliac disease. Computed tomography (CT) abdomen revealed a thickening of the mucosal folds of a short segment of jejunum. He deteriorated and had an exploratory laparotomy and bowel resection with side-side jejojejunal stapled anastomosis and extended right hemicolectomy and ileocolic anastomosis. Histology demonstrated multifocal high-grade malignant T cell lymphoma. Coeliac disease is a very common lifelong disorder. It is associated with osteoporosis, infertility, autoimmune disorders and increased risk of malignancy including an increased risk of non-Hodgkin's lymphoma (NHL) especially of the T cell type. Enteropathy-type T cell lymphoma is associated with a very poor prognosis. There is significant evidence that adherence to a gluten-free diet decreases the risk of developing enteropathy-type T cell lymphoma and helps to prevent development of autoimmune diseases, diabetes mellitus and osteoporosis in patients with coeliac disease.

    Background: The correlation between efficacy end points in randomized controlled trials (RCTs) of systemic therapy for non-Hodgkin's lymphoma (NHL) was investigated to identify an appropriate surrogate end point for overall survival (OS). Methods: RCTs of previously untreated NHL published from 1990 to 2009 were identified. Associations between absolute differences in efficacy end points were determined using nonparametric Spearman's rank correlation coefficients (rs). Results: Thirty-eight RCTs representing 85 treatment arms for aggressive NHL and 20 RCTs representing 42 arms for indolent NHL were included. For aggressive NHL, differences in 3-year progression-free survival (PFS)/event-free survival (EFS) were high correlated with differences in 5-year OS {rs of 0.90 [95% confidence interval (CI) 0.73–0.96]} and linear regression determined that a 10% improvement in 3-year EFS or PFS would predict for a 7% ± 1% improvement in 5-year OS. For indolent histology disease, differences in complete response were strongly correlated with differences in 3-year EFS [rs 0.86 (95% CI 0.35–0.97)], but there was no correlation between 3-year time-to-event end points and 5-year OS. Conclusions: Improvements in 3-year EFS/PFS are highly correlated with improvements in 5-year OS in aggressive NHL and should be explored as a candidate surrogate end point. Definition of these relationships may inform future clinical trial design and interpretation of interim trial data. PMID:21266519

    Is there anything that we can learn from each other regarding paediatric and adult non-Hodgkin Lymphoma (NHL) management? Do we treat the same patients? Are there differences in lymphoma biology in the different age groups? Are the procedures of decision making and the infrastructure comparable? Is the weighing of toxicity and outcome aspects in the benefit and risk assessments prior to treatment decisions comparable? Interestingly, the proportional distribution of the NHL subtypes and the spectrum of NHL occurring in children and adolescents differs significantly from that in adults. This observation might motivate biological studies aiming to elucidate the pathomechanisms of lymphomagenesis. Concerning NHL diagnosis and staging, the comparison of outcome data reported for paediatric and adult patient series is often impaired by the use of different staging systems. However, the impact of reference laboratories supporting correct subtyping and the advantages of population-based patient recruitment are experiences that might be transferable between paediatric and adult oncologists. Interestingly, the process of implementing new drugs into current treatment strategies and making these drugs available to patients varies substantially across patient's age groups. The far lower absolute number of patients, especially of relapsed patients, and the favorable outcome with current standard treatment may contribute to the marked differences in the kinetic of implementing new compounds comparing adult with paediatric NHL patients. Also, the basis for the conduction of cooperative clinical trials with pharmaceutical companies needs to be strengthened in paediatric clinical trial groups. In conclusion, both paediatric and adult oncologists benefit from the interdisciplinary discussion with each other, not only concerning results and experiences in clinical trials but also with respect to critical aspects of infrastructure.

    Non-Hodgkin’s lymphoma (NHL) represents a heterogeneous group of malignancies with high diversity in terms of biology, clinical responses, and prognosis. Standard therapy regimens produce a 5-year relative survival rate of only 69%, with the critical need to increase the treatment-success rate of this patient population presenting at diagnosis with a median age of 66 years and many comorbidities. The evidence that an impaired immune system favors the development of NHL has opened the stage for new therapeutics, and specifically for the adoptive transfer of ex vivo-expanded antigen-specific T-cells. In this review, we discuss how T-cells specific for viral-associated antigens, nonviral-associated antigens expressed by the tumor, T-cells redirected through the expression of chimeric antigen receptors, and transgenic T-cell receptors against tumor cells have been developed and used in clinical trials for the treatment of patients with NHLs.

    Non-Hodgkin's lymphomas include malignant conditions developing within lymphoid tissue, both lymph nodes and extranodal lymphoid tissue. Due to its rich lymphatic supply, the cervico-facial region is frequently involved: 10 to 15% of all NHL (1, 2, 8, 15), i.e. a similar incidence to primary GI involvement (4). The cervical glands and lymphatic structures of the Waldeyer ring are most often and most classically involved. The nasosinusal cavities may be involved, producing diagnostic problems which have to be resolved by the specialist (6). Between 1972 and 1989, 20 cases of NHL involving the bony cavities of the face were seen at the Centre Antoine-Lacassagne. These include the 15 cases reported below involving the naso-sinusal cavities. PMID:2130452

    Marginal zone lymphoma represents about 10% of all non-Hodgkin lymphomas (NHLs). 33% of patients with acquired angioedema (AAE) due to acquired C1-inhibitor (C1-INH) deficiency (C1-INH-AAE) have or will develop NHLs. C1-INH-AAE is a rare condition. We report the follow-up of 72 C1-INH-AAE patients, followed for a median of 15 years (range 1-24). Median age was 71 (range 64-79) years; median age at onset of angioedema symptoms was 57·5 (range 50-66) years and it was 63 [range 45-80) years at diagnosis]. Twenty patients were diagnosed with low-grade non-follicular B-cell lymphomas (75% were splenic MZL), one with follicular and three with high-grade lymphomas (two diffuse large B-cell lymphomas and one mantle cell lymphoma). Fifteen NHLs were diagnosed at onset of AAE or thereafter (3 months to 7 years), eight had already been diagnosed at onset of angioedema. Two of 24 patients remain on watchful wait. Thirthen of 24 received chemotherapy, two received rituximab. Three underwent splenectomy. All 18 patients receiving therapy for NHL experienced post-treatment reduction in AAE symptoms. Our study suggests that clonal B-cell proliferation is the pathology underlying AAE leading to production of C1-INH-neutralizing autoantibodies and to NHLs. The post-germinal centre origin of NHL suggests that immune stimulation may contribute to lymphomagenesis. PMID:26728240

    Relative age effects (RAEs) occur when those who are relatively older for their age group are more likely to succeed. RAEs occur reliably in some educational and athletic contexts, yet the causal mechanisms remain unclear. Here we provide the first direct test of one mechanism, selection bias, which can be defined as evaluators granting fewer opportunities to relatively younger individuals than is warranted by their latent ability. Because RAEs are well-established in hockey, we analyzed National Hockey League (NHL) drafts from 1980 to 2006. Compared to those born in the first quarter (i.e., January–March), those born in the third and fourth quarters were drafted more than 40 slots later than their productivity warranted, and they were roughly twice as likely to reach career benchmarks, such as 400 games played or 200 points scored. This selection bias in drafting did not decrease over time, apparently continues to occur, and reduces the playing opportunities of relatively younger players. This bias is remarkable because it is exhibited by professional decision makers evaluating adults in a context where RAEs have been widely publicized. Thus, selection bias based on relative age may be pervasive. PMID:23460902

    Background: Non-Hodgkin's lymphomas (NHL) have a great tendency to affect organs and tissues that do not ordinarily contain lymphoid cells. Involvement of the oral cavity by NHL is very rare. Materials and Methods: Retrospective analysis was carried out by chart review of patients who presented to our hospital between 1990 and 2008. All those patients whose histopathology at our hospital was confirmed as lymphoma were included. Results: Although we register nearly 2000 new oral cancers every year, most of which are squamous cell cancers, we could trace only 15 cases of oral lymphoma in the last 18 years. Of these, hard palate and alveolus were most common sites (5 each). The median age at presentation was 42.6 years. A vast majority (12/15) were NHL. Most patients (70%) reported with painless progressive swelling without systemic signs, such as fever, weight loss, and so on. Only 2 patients were HIV positive. Nearly two thirds received combinations of CT and RT. Cyclophosphamide, hydroxydaunorubicin, oncovin (vincristine), prednisolone regime was the most common regime offered (12/15). Most of them (67%) had good response to 6 cycles of CT that was followed by RT. 10/15 patients completed treatment. Follow-up data of more than 2 years of follow-up was present in 11/15 patients. With median follow-up of 27 months, 5 were disease free, 5 died, and 1 controlled following 2nd line of CT, 2 were lost to follow-up and 2 were alive with disease. Discussion: Head and neck lymphoma is the second most common region for extranodal lymphoma. The nasopharynx, tonsils, and base tongue are most often involved. Unlike the western world, oral cavity involvement is extremely rare. Interestingly, only 2 patients tested positive for HIV and most were young patients. Oral lymphoma may mimic benign oral conditions that often lead to misdiagnosis. Conclusion: Although oral cavity may be the preferred site of NHL in immunocompromised patients it does occur in immunocompetent patients as

    Purpose Few studies to date have evaluated factors associated with the development of radiation pneumonitis (RP) in patients with Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL), especially in patients treated with contemporary radiation techniques. These patients represent a unique group owing to the often large radiation target volumes within the mediastinum and to the potential to receive several lines of chemotherapy that add to pulmonary toxicity for relapsed or refractory disease. Our objective was to determine the incidence and clinical and dosimetric risk factors associated with RP in lymphoma patients treated with intensity modulated radiation therapy (IMRT) at a single institution. Methods We retrospectively reviewed clinical charts and radiation records of 150 consecutive patients who received mediastinal IMRT for HL and NHL from 2009 through 2013. Clinical and dosimetric predictors associated with RP per the Radiation Therapy Oncology Group (RTOG) acute toxicity criteria were identified in univariate analysis using the Pearson χ2 test and logistic multivariate regression. Results Mediastinal radiation was administered as consolidation therapy in 110 patients with newly diagnosed HL or NHL and in 40 patients with relapsed or refractory disease. The overall incidence of RP (RTOG grade 1–3) was 14% in the entire cohort. Risk of RP was increased for patients who received radiation for relapsed or refractory disease (25%) versus those who received consolidation (10%, P=0.019). Several dosimetric parameters predicted RP, including mean lung dose (MLD) >13.5 Gy, V20 >30%, V15 >35%, V10 >40% and V5>55%. The likelihood ratio (LR) χ2 value was highest for V5< 55% (LR χ2=19.37). Conclusions In using IMRT to treat mediastinal lymphoma, all dosimetric parameters predicted RP, although small doses to large volumes of lung had the greatest influence.

    Objective(s): Non- Hodgkin lymphoma (NHL) and acute lymphoblastic leukemia (ALL) are two main hematological malignances which have been driven from lymphoid tissue. Genetic polymorphisms in tumor necrosis factor-α (TNF-α) -308 and lymphotoxin-α (LT-α) +252 may affect their transcription and expression which leads to their high plasma level. The frequency of the TNF-α (-308) and LT-α (+ 252) polymorphisms are different for NHL and ALL cases in various populations with different ethnicity. This research is designed to investigate the prevalence and association of TNF-α (-308) and LT-α (+ 252) polymorphisms from NHL and ALL in Azarian patients and healthy individuals from Northwestern part of Iran. Materials and Methods: Seventy subjects with ALL and 68 NHL, along with another 130 healthy subjects as control group took part in this study. Genomic DNA was extracted, then genetic polymorphisms in TNF-α and LT-α genes were analyzed with the PCR-RFLP and NCOI as restriction enzyme. A statistical analysis was performed by chi-square test using SPSS software. A P-value of <0.05 was considered statistically significant. Results: A statistically significant difference of LT-α polymorphism was in NHL patients and control (P-value= 0.008) but there was not any association of TNF-α polymorphism between NHL patients and control group. A significant association for TNF-a variant was in ALL and control (P-value =0.005), however, there was no relationship about LT variant between ALL and control. Conclusion: The results show that there are significant differences between TNF-α (-308) and LT-α (+252) genetic polymorphisms respectively in ALL and NHL patients with control group from Northwestern part of Iran.

    The association between consumption of red and processed meat and non-Hodgkin lymphoma (NHL) remains unclear. We performed a meta-analysis of the published observational studies to explore this relationship.We searched databases in MEDLINE and EMBASE to identify observational studies which evaluated the association between consumption of red and processed meat and risk of NHL. Quality of included studies was evaluated using Newcastle-Ottawa Quality Assessment Scale (NOS). Random-effects models were used to calculate summary relative risk (SRR) and the corresponding 95% confidence interval (CI).We identified a total of 16 case-control and 4 prospective cohort studies, including 15,189 subjects with NHL. The SRR of NHL comparing the highest and lowest categories were 1.32 (95% CI: 1.12-1.55) for red meat and 1.17 (95% CI: 1.07-1.29) for processed meat intake. Stratified analysis indicated that a statistically significant risk association between consumption of red and processed meat and NHL risk was observed in case-control studies, but not in cohort studies. The SRR was 1.11 (95% CI: 1.04-1.18) for per 100 g/day increment in red meat intake and 1.28 (95% CI: 1.08-1.53) for per 50 g/day increment in processed meat intake. There was evidence of a nonlinear association for intake of processed meat, but not for intake of red meat.Findings from our meta-analysis indicate that consumption of red and processed meat may be related to NHL risk. More prospective epidemiological studies that control for important confounders and focus on the NHL risk related with different levels of meat consumption are required to clarify this association.

    Although in decline after successful anti-HIV therapy, B-cell lymphomas are still elevated in HIV-1-seropositive (HIV+) persons, and the mechanisms are obscure. The HIV-1 matrix protein p17 persists in germinal centers long after HIV-1 drug suppression, and some p17 variants (vp17s) activate Akt signaling and promote growth of transformed B cells. Here we show that vp17s derived from four of five non-Hodgkin lymphoma (NHL) tissues from HIV+ subjects display potent B-cell growth-promoting activity. They are characterized by amino acid insertions at position 117–118 (Ala–Ala) or 125–126 (Gly–Asn or Gly–Gln–Ala–Asn–Gln–Asn) among some other mutations throughout the sequence. Identical dominant vp17s are found in both tumor and plasma. Three of seven plasma samples from an independent set of NHL cases manifested multiple Ala insertions at position 117–118, and one with the Ala–Ala profile also promoted B-cell growth and activated Akt signaling. Ultradeep pyrosequencing showed that vp17s with C-terminal insertions are more frequently detected in plasma of HIV+ subjects with than without NHL. Insertion of Ala–Ala at position 117–118 into reference p17 (refp17) was sufficient to confer B-cell growth-promoting activity. In contrast, refp17 bearing the Gly–Asn insertion at position 125–126 did not, suggesting that mutations not restricted to the C terminus can also account for this activity. Biophysical analysis revealed that the Ala–Ala insertion mutant is destabilized compared with refp17, whereas the Gly–Asn form is stabilized. This finding provides an avenue for further exploration of structure function relationships and new treatment strategies in combating HIV-1–related NHL. PMID:26578780

    Patients with primary progressive or refractory Hodgkin's disease (HD) or aggressive non-Hodgkin's lymphoma (NHL) have a particularly poor prognosis. Here we report the results of autologous tandem transplantation in these patients. Patients aged 18-55 years with primary progressive or refractory relapsed HD and aggressive NHL were included. Patients received high-dose etoposide (2000 mg/m(2)) followed by peripheral blood stem cell harvest (PBSC). The first high-dose chemotherapy (TMC) consisted of thiotepa (750 mg/m(2)), mitoxantrone (40 mg/m(2)), and carboplatin (990 mg/m(2)). Patients with no change (NC), partial remission (PR), or complete remission (CR) after TMC then received BEAM with carmustine (300 mg/m(2)), etoposide (1200 mg/m(2)), cytarabine (1600 mg/m(2)), and melphalan (140 mg/m(2)). Patients with bulky disease (>5 cm) or residual lymphoma received involved field radiotherapy. Twenty-five patients were included (HD=10, NHL=15, median age 34 years). Two patients with HD achieved a CR and five patients a PR [response rate (RR) 70%]. Three patients (30%) experienced treatment failure including two deaths due to peritransplant complications. Five patients with aggressive NHL were in CR and two patients in PR (RR 46%). Of the eight patients (56%) with treatment failure, three had progressive disease and five died from peritransplant complications. Freedom from treatment failure (FFTF) and overall survival (OS) for all patients after 12 months was 28% and 40%, respectively. Tandem HDCT followed by autologous stem cell transplantation (ASCT) offers a chance of cure in these poor prognostic patients, but is associated with risks. PMID:15759115

    Several small studies suggest a link between environmental exposure to organochlorine compounds and risk of non Hodgkin's lymphoma (NHL). Because NHL is uncommon, studies of the topic often use a population-based case-control design, in which cases generally are enrolled after treatment has begun. If chemotherapy affects blood levels of organochlorines, exposure will be misclassified and findings distorted. To determine whether chemotherapy alters serum levels of organochlorines in NHL cases, we compared serum samples before and after treatment in 22 cases diagnosed with NHL between March 1994 and August 1995 and enrolled in a clinical trial at the United States National Cancer Institute's Clinical Center. The time difference between pretreatment and posttreatment samples ranged from 15 to 27 months with an average of 20 months. Laboratory analyses were conducted in blinded pretreatment and posttreatment pairs of the subjects. Pretreatment and posttreatment organochlorine serum levels were compared using Pearson correlation coefficient (r) and paired t test. The pretreatment and posttreatment serum levels were highly correlated for 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (DDE) and polychlorinated biphenyls (PCBs) PCB-138, PCB-153, PCB-156, and total PCBs (ranging from 0.78 to 0.93). Serum levels of all of these organochlorines significantly decreased between initiation and completion of chemotherapy, 25% for total PCB (P = 0.0044), 28% for DDE (P = 0.0014), 25% for PCB-138 (P = 0.0053), 27% for PCB-153 (P = 0.0031), and 29% for PCB-156 (P = 0.045). Neither weight change nor lipid change was correlated with changes in chemical levels. There was no association between the length of time between blood draws and changes in chemical levels. Our data raise the possibility that lymphoma treatment depresses serum organochlorine levels. PMID:10698481

    The US and Queensland populations both demonstrate an increased risk of secondary malignancies following the diagnosis of Merkel cell carcinoma (MCC). A recent Queensland study failed to demonstrate a significantly increased risk of developing non-Hodgkin lymphoma (NHL) or chronic lymphocytic leukaemia (CLL) in these patients. In contrast, using the US Surveillance, Epidemiology, and End Results database, we demonstrate there is an increased risk in CLL and NHL following the diagnosis of MCC in the USA. We hypothesise that this difference may be a result of a differing pathogenesis. PMID:25801041

    Is the decline of the increasing incidence of non-Hodgkin lymphoma (NHL) in Sweden and other countries a result of cancer preventive measures? The yearly age-standardized incidence of NHL increased significantly in Sweden during 1971-1990, for men an average of 3.2% and for women 3.1%. The corresponding figures for 1991-2000 were -0.8% and -0.2%, respectively. A decline of the increasing incidence has also been seen in other countries, such as the United States, Finland, and Denmark. Immunosuppression is one established risk factor for NHL, possibly with interaction with Epstein-Barr virus. Phenoxyacetic acids and chlorophenols, both pesticides, have been associated with NHL. Use of these chemicals was banned in Sweden in 1977 and 1978, respectively. Also, persistent organic pollutants such as polychlorinated biphenyls, hexachlorobenzene, chlordanes, and dioxins have been shown to increase the risk. Exposure of the whole population occurs predominantly through the food chain. Exposure to such chemicals was highest in the 1960s and 1970s. Because of regulation in the 1970s, exposure has declined substantially in the population. The change in incidence of NHL in Sweden and other countries may serve as a good example of how prohibition and limitation of exposure may be reflected in cancer statistics some decades later.

    Veltuzumab is a humanized, second-generation anti-CD20 mAb currently under development by Immunomedics Inc for the potential treatment of B-cell non-Hodgkin's lymphoma (NHL) and chronic lymphocytic leukemia (CLL). Licensee Nycomed is developing veltuzumab for the potential treatment of rheumatoid arthritis and immune thrombocytopenic purpura (ITP). Veltuzumab contains 90 to 95% human antibody sequences with identical antigen framework regions to epratuzumab (a humanized anti-CD22 mAb) and similar antigen-binding determinants to rituximab (chimeric, anti-CD20 mAb and the first-line treatment of aggressive and indolent NHL). In vitro studies have demonstrated that veltuzumab has enhanced binding avidities and a stronger effect on complement-dependent cytotoxicity compared with rituximab in selected cell lines. In dose-finding phase I/II clinical trials in patients with low-grade NHL, intravenous veltuzumab demonstrated a substantial rate of complete responses in concurrence with shorter and more tolerable infusions compared with rituximab. Currently there has been no evidence of an immune response to repeated administrations, and no serious adverse events related to veltuzumab treatment in patients with NHL. Veltuzumab is undergoing clinical trials using a low-dose subcutaneous formulation in patients with NHL, CLL and ITP. Prospective, randomized clinical trials are needed to clarify the role veltuzumab will play in a market where the therapy of B-cell lymphoproliferative disorders is dominated by rituximab.

    Aims To identify occupations and industries associated with non-Hodgkin lymphoma in a large population-based case-control study in the United States. Methods Cases (n = 1,189) of histologically confirmed malignant NHL ages 20–74 were prospectively identified in four geographic areas covered by the National Cancer Institute SEER Program. Controls (n = 982) were selected from the general population by random digit dialing (< 65 years of age) and from residents listed in Medicare files (65–74 years of age). Odds ratios and 95% confidence intervals for occupations and industries were calculated by unconditional logistic regression analyses, adjusting for age, gender, ethnicity, and study center. Further analyses stratified for gender and histological subtype were also performed. Results Risk of NHL was increased for a few occupations and industries. Several white collar occupations, with no obvious hazardous exposures, had elevated risks, including purchasing agents and buyers, religious workers, physical therapists, and information clerks. Occupations with excesses that may have exposures of interest include launderers and ironers, service occupations, food/beverage preparation supervisors, hand packers and packagers, roofing and siding, leather and leather products, transportation by air, nursing and personal care facilities, and specialty outpatient clinics. Significantly decreased risks of NHL were found for a number of occupations and industries including post secondary teachers and chemical and allied products. Conclusions The results of this study suggest that several occupations and industries may alter the risk of NHL. Our results support previously reported increased risks among farmers, printers, medical professionals, electronic workers, and leather workers. These findings should be evaluated further in larger studies that have the power to focus on specific exposures and histologic subtypes of NHL. PMID:18805886

    In this nested case-control study we examined the relationship between non-Hodgkin's lymphoma (NHL) and organochlorine pesticide exposure. We used a data set originally collected between 1969 and 1983 in the U.S. Environmental Protection Agency National Human Adipose Tissue Survey. Adipose samples were randomly collected from cadavers and surgical patients, and levels of organochlorine pesticide residues were determined. From the original study population, 175 NHL cases were identified and matched to 481 controls; 173 controls were selected from accident victims, and 308 from cases with a diagnosis of myocardial infarction. Cases and controls were mainly from cadavers (> 96%) and were matched on sex, age, region of residence within the United States, and race/ethnicity. Conditional logistic regression showed the organochlorine pesticide residue heptachlor epoxide to be significantly associated with NHL [compared with the lowest quartile: third quartile odds ratio (OR) = 1.82, 95% confidence interval (CI), 1.01-3.28; fourth quartile OR = 3.41, 95% CI, 1.89-6.16]. The highest quartile level of dieldrin was also associated with elevated NHL risk (OR = 2.70; 95% CI, 1.58-4.61), as were higher levels of oxychlordane, p,p'-DDE [p,p'-1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene], and ss-benzene hexachloride (ORs = 1.79, 1.99, and 2.47, respectively). The p-values for trends for these associations were significant. In models containing pairs of pesticides, only heptachlor epoxide and dieldrin remained significantly associated with risk of NHL. Limitations of this study include collection of samples after diagnosis and a lack of information on variables affecting organochlorine levels such as diet, occupation, and body mass index. Given the persistence of pesticides in the environment, these findings are still relevant today. PMID:15175172

    Exposure to diagnostic x-rays and the risk of leukemia, non-Hodgkin's lymphoma (NHL), and multiple myeloma were studied within two prepaid health plans. Adult patients with leukemia (n = 565), NHL (n = 318), and multiple myeloma (n = 208) were matched to controls (n = 1390), and over 25,000 x-ray procedures were abstracted from medical records. Dose response was evaluated by assigning each x-ray procedure a score based on estimated bone marrow dose. X-ray exposure was not associated with chronic lymphocytic leukemia, one of the few malignant conditions never linked to radiation (relative risk (RR), 0.66). For all other forms of leukemia combined (n = 358), there was a slight elevation in risk (RR, 1.17) but no evidence of a dose-response relationship when x-ray procedures near the time of diagnosis were excluded. Similarly, patients with NHL were exposed to diagnostic x-ray procedures more often than controls (RR, 1.32), but the RR fell to 0.99 when the exposure to diagnostic x-ray procedures within 2 years of diagnosis was ignored. For multiple myeloma, overall risk was not significantly high (RR, 1.14), but there was consistent evidence of increasing risk with increasing numbers of diagnostic x-ray procedures. These data suggest that persons with leukemia and NHL undergo x-ray procedures frequently just prior to diagnosis for conditions related to the development or natural history of their disease. There was little evidence that diagnostic x-ray procedures were causally associated with leukemia or NHL. The risk for multiple myeloma, however, was increased among those patients who were frequently exposed to x-rays.

    This Swedish nationwide cohort study aims to examine the role of maternal characteristics (maternal age, education, smoking, BMI, diabetes, and preeclampsia) and multiple intrauterine growth measures on the risk of childhood lymphomas. A total of 3 444 136 singleton live births registered in the Swedish Medical Birth Register were analyzed, among whom there were 515 incident non-Hodgkin lymphoma (NHL) cases and 169 Hodgkin lymphoma (HL) cases aged 0-14 years at diagnosis (1973-2007) identified through linkage with the Swedish Cancer Register. Proportional hazards models were used to estimate the hazard ratio (HR) and 95% confidence intervals (95% CI) of NHL and HL. Male sex (HR=2.00, 95% CI: 1.66-2.41), older maternal age (HR=1.03, 95% CI: 1.00-1.06, per 1-year increase), and large for gestational age compared with appropriate for gestational age (AGA) birth weight (HR=1.83, 95% CI: 1.20-2.79) were correlated with the risk of NHL; of note, in subanalysis by sex, the latter association was confined to girls (HR=3.37, 95% CI: 1.90-5.97, Pinteraction by sex=0.008). The risk of childhood HL overall was more evident among boys (HR=2.03, 95% CI: 1.46-2.81), whereas indices of accelerated fetal growth were not convincingly associated with the risk of HL. Apart from the established association with sex, the findings point to accelerated intrauterine growth as a risk factor for childhood NHL that may differ by sex. Given the rarity of this condition at birth, however, further studies with more elaborate indices are needed to conclude on its association with rare diseases such as HL. PMID:25569452

    High-dose therapy and autologous stem cell transplantation (HDT-ASCT) can offer potential long-term remission or cure in patients with non-Hodgkin lymphoma (NHL). Limited experience is available on the safety and efficacy of HDT-ASCT in elderly patients. This is a single-center, retrospective study examining outcomes of HDT-ASCT for 202 NHL patients, ages 60 years and older, between January 2001 and December 2012. Overall survival (OS) and progression-free survival (PFS) were analyzed according to age at HDT-ASCT, hematopoietic cell transplantation comorbidity index (HCT-CI), NHL histology, and remission status at the time of HDT-ASCT. The median age was 65 years (range, 60 to 74) and the majority had either diffuse large B cell lymphoma (n = 73, 37%) or mantle cell lymphoma (n = 69, 34%). One hundred and fifteen patients (57%) had high HCT-CI scores at the time of HDT-ASCT. With a median follow-up of 3.6 years (range, 4 to 11.9 years) for survivors, PFS and OS at 3 years were 60% (95% confidence interval [CI], 53% to 68%) and 73% (95% CI, 67% to 80%), respectively. Transplantation-related mortality (TRM) was 4% both at 100 days and at 1 year after HDT-ASCT. Age and HCT-CI score were not associated with OS or PFS, and high HCT-CI did not correlate with TRM. Seven patients (4%) developed secondary myelodysplastic syndrome or acute myeloid leukemia at a median of 35 months (range, 6 to 48) after HDT-ASCT. In this single-center cohort of elderly patients with NHL undergoing HDT-ASCT, this intervention was proven tolerable and effective, with results similar to those of historic controls in younger patients. Our data suggest that age alone should not preclude HDT-ASCT in elderly patients. PMID:25175794

    A secondary analysis of 1999–2002 Nebraska case-control data was conducted to assess the risk of non-Hodgkin lymphoma (NHL) associated with exposure to nitrate- and atrazine-contaminated drinking water. Water chemistry data were collected and weighted by well contribution and proximity of residence to water supply, followed by logistic regression to determine odds ratios (OR) and 95% confidence intervals (CI). We found no association between NHL risk and exposure to drinking water containing atrazine or nitrate alone. Risk associated with the interaction of nitrate and atrazine in drinking water was elevated (OR, 2.5; CI, 1.0–6.2). Risk of indolent B-cell lymphoma was higher than risk of aggressive B-cell lymphoma (indolent: OR, 3.5; CI, 1.0–11.6 vs. aggressive: OR, 1.9; CI, 0.6–5.58). This increased risk may be due to in vivo formation and subsequent metabolism of N-nitrosoatrazine. A larger study is warranted to confirm our findings. PMID:23515852

    18F-Fluorodeoxyglucose (FDG) PET has become an important tool in the management of non-Hodgkin’s lymphoma (NHL), but its role in the evaluation of primary CNS lymphoma (PCNSL) has not been established. We investigated the ability of body FDG PET to detect systemic disease in the staging and restaging of PCNSL. The records of 166 PCNSL patients seen at Memorial Sloan-Kettering Cancer Center were examined. Forty-nine patients who underwent body FDG PET for staging of PCNSL were identified. Clinical data were reviewed to determine FDG PET results and their influence on therapy. Body FDG PET disclosed a systemic site of malignancy in 15% of patients. NHL was found in 11% of all patients, 7% of patients at diagnosis, and 27% of patients at CNS relapse. Four percent had a second systemic neoplasm. Workup with conventional staging did not reveal systemic disease, and in 8% of patients, body FDG PET was the only abnormal diagnostic exam suggestive of lymphoma. FDG PET findings altered patient treatment and resulted in additional chemotherapy, surgery, or radiotherapy. Our findings suggest that FDG PET may be more sensitive than conventional body staging and may disclose higher rates of concomitant systemic disease at PCNSL diagnosis. Body FDG PET may be an important noninvasive adjunct to conventional PCNSL staging, and its utility should be evaluated prospectively. PMID:18287338

    We report a 72-year-old female patient with diffuse large B cell non-Hodgkin's lymphoma (NHL) with previous treatment with standard chemotherapy presenting as an acute, ascending, sensorimotor polyneuropathy. Nerve conduction studies and lumbar puncture supported a rare, but ominous, axonal variant of Guillain-Barré Syndrome (GBS) known as acute motor and sensory axonal neuropathy (AMSAN), which is distinguished from the more common, acute demyelinating forms of GBS. Previous reports have largely focused on toxicities secondary to chemo- or radiotherapy as a major contributor to the development of acute neuropathies in malignancy. Clinicians should also be mindful of direct neoplastic invasion or, less commonly, paraneoplastic phenomenon, as alternative mechanisms, the latter possibly reflecting immune dysregulation in particularly aggressive lymphomas. At the time of writing, this is the first report in the literature of an axonal variant of GBS in a patient with diffuse large B cell NHL. A discussion regarding common and uncommon neuropathies in haematological malignancies is made, with a brief review of the anecdotal evidence supporting a paraneoplastic association with GBS or its variant forms in the setting of lymphoma.

    PCNA is a 36-KD proliferating cell nuclear antigen associated with the cell cycle. The immunocytochemical detection of PCNA represents a useful tool for the study of tumor proliferation activity. This study documents the detection of PCNA, using antibody PC 10 in formalin-fixed, paraffin-embedded tissue, and correlates the proliferative activity of the non-Hodgkin's lymphomas (NHL) with histological grading assessed by the International Working Formulation (WF) and Kiel classification. In 92 cases of NHLs we found a strong correlation between the PCNA index and lymphoma grading. Statistically significant differences were also found between the proliferative index (PI) in low and high grade lymphomas according to the Kiel classification (t = 9.519; p < 0.001) and between low, intermediate and high grade lymphomas according to the WF classification (F = 79.01; p < 0.001). In the Kiel classification the mean of low grade lymphomas was 39.5% and of high grade 75.7%. In the WF the average of low grade lymphomas was 29.7%, intermediate 53.1% and high 75.1%. Although the differences among the groups had been significant, we found variations inside each histological subgroup in both classifications. The intermediate lymphomas were the most heterogeneous group, with PI inside the same histologic subtypes coincident with low and high grade lymphomas. Since PCNA may be used as a marker of cell proliferation in clinical studies to estimate the biological aggressiveness of lymphomas, its determination in intermediate grade NHL could be very useful to evaluate individual cases in this group and determine prognosis and probably the appropriate therapy.

    Non-Hodgkin lymphomas include a biologically and clinically heterogeneous group of cancers distinguished by genetics, histology, and treatment outcomes. New discoveries regarding the genomic alterations and epidemiological exposures associated with these lymphomas have enhanced our understanding of factors that contribute to lymphomagenesis for specific subtypes. We explore the impact of normal B-cell biology engineered for recognizing a wide variety of antigens on the development of specific lymphoma subtypes, review lymphoma genetics, and examine the epidemiology of B-cell NHLs including recent investigations of risk factors for particular lymphoma subtypes based on large pooled analyses. Burkitt lymphoma, an aggressive form of B-cell NHL involving translocation of the MYC gene and an immunoglobulin gene has been associated with a history of eczema, hepatitis C, and occupation as a cleaner. Increased risk of diffuse large B-cell lymphoma has been associated with increased young adult body mass index, history of B-cell-activating autoimmune diseases, hepatitis C, and several single nucleotide variants involving the human leukocyte antigen (HLA) region of chromosome 6 and non-HLA loci near EXOC2, PVT1, MYC, and NCOA1. Tumor sequencing studies suggest that multiple pathways are involved in the development of DLBCL. Additional studies of epidemiological exposures, genome wide associations, and tumor sequencing in follicular, lymphoplasmacytic, marginal zone, and mantle cell lymphoma demonstrate overlapping areas of increased risk factors and unique factors for specific subtypes. Integrating these findings is important for constructing comprehensive models of NHL pathogenesis, which could yield novel targets for therapy and strategies for lymphoma prevention in certain populations.

    Objective The development of non-Hodgkin's lymphoma (NHL) confers a high risk of mortality in primary Sjögren's syndrome (pSS) patients, but the sensitivity and specificity of proposed lymphoma predictors are insufficient for practical use. The performance of lymphoid organisation in the form of germinal centre (GC)-like lesions was evaluated in labial salivary gland biopsies taken at pSS diagnosis as a potential lymphoma-predicting biomarker. Methods Labial salivary gland tissue biopsies available from two Swedish pSS research cohorts (n=175) were re-evaluated by light microscopy in a blind study in order to identify GC-like structures as a sign of ectopic lymphoid tissue formation and organisation. A linkage study was performed with the Swedish Cancer Registry for lymphoma identification. The risk of developing NHL in GC-positive patients in comparison with GC-negative patients was evaluated using Kaplan–Meier statistics and log-rank test. Associations between GC-like structures and clinical and/or laboratory disease markers were also determined using χ2 or Fisher's exact tests. Results At diagnosis, 25% of pSS patients had GC-like structures in their salivary glands. Seven of the 175 patients studied (14% GC+ and 0.8% GC−) developed NHL during 1855 patient-years at risk, with a median onset of 7 years following the initial diagnostic salivary gland biopsy. Six of the seven patients had GC-like structures at diagnosis; the remaining patient was GC negative at the time of diagnosis (p=0.001). Conclusions The detection of GC-like structures by light microscopy in pSS diagnostic salivary biopsies is proposed as a highly predictive and easy-to-obtain marker for NHL development. This allows for risk stratification of patients and the possibility to initiate preventive B-cell-directed therapy. PMID:21715359

    Restricted T-cell receptor (TCR) Vα/Vβ repertoire expression and clonal expansion of αβ T cells especially for putative tumor-associated antigens were observed in patients with hematological malignancies. To further characterize the γδ T-cell immune status in B-cell non-Hodgkin lymphoma (B-NHL), we investigated the distribution and clonality of TCR Vγ/Vδ repertoire in peripheral blood (PB), bone marrow (BM), and lymph node (LN) from patients with B-NHL. Four newly diagnosed B-NHL cases, including three with diffuse large B-cell lymphoma (DLBCL) and one with small lymphocytic lymphoma (SLL), were enrolled. The restrictive expression of TCR Vγ/Vδ subfamilies with different distribution patterns could be detected in PB, BM, or LN from all of four patients, and partial subfamily T cells showed clonal proliferation. At least one clonally expanded Vδ subfamily member was found in PB from each patient. However, the expression pattern and clonality of TCR Vγ/Vδ changed in different immune organs and showed individual feature in different patients. The clonally expanded Vδ5, Vδ6, and Vδ8 were detected only in PB but neither in BM nor LN while clonally expanded Vδ2 and Vδ3 could be detected in both PB and BM/LN. In conclusion, the results provide a preliminary profile of distribution and clonality of TCR γ/δ subfamilies T cells in PB, BM, and LN from B-NHL; similar clonally expanded Vδ subfamily T cells in PB and BM may be related to the same B-cell lymphoma-associated antigens, while the different reactive clonally expanded Vγ/Vδ T cells may be due to local immune response.

    The goal of this study was to investigate damaged liver function after chemotherapy in hepatitis B virus (HBV) carriers with non-Hodgkin lymphoma (NHL) and to evaluate risk factors associated with a high risk of damaged liver function. Clinical histories of 134 HBV carriers with NHL who were treated with chemotherapy were obtained and analyzed for the occurrence of damaged liver function and other related high-risk factors. Analysis showed that 76 patients (56.7%) had damaged liver function after chemotherapy: 6 patients (7.9%) had I degree, 17 patients (22.4%) had II degree, 20 patients (26.3%) had III degree, and 33 patients (43.4%) had IV degree damage. After treatment, 18 patients (23.7%) continued to receive chemotherapy according to their original schedule, 39 patients (51.3%) delayed chemotherapy, 16 patients (21.1%) stopped chemotherapy, and 3 patients (3.9%) died. Analysis of a binary multivariate logistic regression model showed that administration of steroids was a high-risk factor for damaged liver function after chemotherapy in NHL patients. The incidence of damaged liver function after chemotherapy is high among HBV carriers with NHL; therefore, administration of steroid chemotherapy is a high-risk factor. PMID:25867413

    We performed a pooled analysis of data on self-reported history of infections in relation to the risk of non-Hodgkin lymphoma (NHL) from 17 case-control studies that included 12,585 cases and 15,416 controls aged 16–96 years at recruitment. Pooled odds ratios (OR) and 95% confidence intervals (95% CI) were estimated in two-stage random-effect or joint fixed-effect models, adjusting for age, sex and study centre. Data from the two years prior to diagnosis (or date of interview for controls) were excluded. A self-reported history of infectious mononucleosis (IM) was associated with an excess risk of NHL (OR=1.26, 95% CI=1.01–1.57 based on data from 16 studies); study-specific results indicate significant (I2=51%, p=0.01) heterogeneity. A self-reported history of measles or whooping cough was associated with an approximate 15% reduction in risk. History of other infection was not associated with NHL. We find little clear evidence of an association between NHL risk and infection although the limitations of data based on self-reported medical history (particularly of childhood illness reported by older people) are well recognised.

    Aurora kinases are oncogenic serine/threonine kinases that play key roles in regulating the mitotic phase of the eukaryotic cell cycle. Auroras are overexpressed in numerous tumors including B-cell non-Hodgkin's lymphomas and are validated oncology targets. AT9283, a pan-aurora inhibitor inhibited growth and survival of multiple solid tumors in vitro and in vivo. In this study, we demonstrated that AT9283 had potent activity against Aurora B in a variety of aggressive B-(non-Hodgkin lymphoma) B-NHL cell lines. Cells treated with AT9283 exhibited endoreduplication confirming the mechanism of action of an Aurora B inhibitor. Also, treatment of B-NHL cell lines with AT9283 induced apoptosis in a dose and time dependent manner and inhibited cell proliferation with an IC(50) < 1 μM. It is well known that inhibition of auroras (A or B) synergistically enhances the effects of microtubule targeting agents such as taxanes and vinca alkaloids to induce antiproliferation and apoptosis. We evaluated whether AT9283 in combination with docetaxel is more efficient in inducing apoptosis than AT9283 or docetaxel alone. At very low doses (5 nM) apoptosis was doubled in the combination (23%) compared to AT9283 or docetaxel alone (10%). A mouse xenograft model of mantle cell lymphoma demonstrated that AT9283 at 15 mg/kg and docetaxel (10 mg/kg) alone had modest anti-tumor activity. However, AT9283 at 20 mg/kg and AT9283 (15 or 20 mg/kg) plus docetaxel (10 mg/kg) demonstrated a statistically significant tumor growth inhibition and enhanced survival. Together, our results suggest that AT9283 plus docetaxel may represent a novel therapeutic strategy in B-cell NHL and warrant early phase clinical trial evaluation. PMID:21796626

    Prognosis is poor for patients with biologically aggressive Non-Hodgkin lymphoma (NHL), refractory to chemotherapy or relapsed after autologous transplantation, especially when no disease control before allogeneic transplantation is achieved. In 16 patients (median age 53, median prior regimes 5) with relapsed or refractory non-remission NHL, we analysed retrospectively the efficacy of a sequential therapy comprising clofarabine re-induction followed by a reduced-intensity conditioning with fludarabine, CY and melphalan, and T-cell-replete HLA-haploidentical transplantation. High-dose CY was utilized post-transplantation. All patients engrafted. Early response (day +30) was achieved in 94%. Treatment-related grade III-IV toxicity occurred in 56%, most commonly transient elevation of transaminases (36%), while there was a low incidence of infections (19% CMV reactivation, 19% invasive fungal infection) and GVHD (GVHD: acute III-IV: 6%; mild chronic: 25%). One-year non-relapse mortality was 19%. After a median follow-up of 21 months, estimated 1- and 2-year PFS was 56 and 50%, respectively, with 11 patients (69%) still alive after 2 years. In summary, sequential therapy is feasible and effective and provides an acceptable toxicity profile in high-risk non-remission NHL. Presumably, cytotoxic reinduction with clofarabine provides enough remission time for the graft-versus lymphoma effect of HLA-haploidentical transplantation to kick in, even in lymphomas that are otherwise chemo-refractory.

    With the introduction of newer therapeutic approaches, survival in indolent non-Hodgkin's lymphoma (NHL) appears to be improving. Mitoxantrone (Novantrone; Serono, Inc.; Rockland, MA, http://www.seronousa.com), an anthracenedione with low cardiotoxic potential, has demonstrated activity in indolent NHL in combination with fludarabine (Fludara; Berlex Laboratories; Wayne, NJ, http://www.berlex.com) and other agents. In a Southwest Oncology Group trial (SWOG 9501), treatment with fludarabine and mitoxantrone (FM) induced a complete remission (CR) rate of 44% and a partial remission (PR) rate of 50% in untreated patients. The estimated 4-year progression-free survival (PFS) rate was 38%. In a multicenter Italian trial comparing the efficacy of FM with that of cyclophosphamide, doxorubicin (Adriamycin; Bedford Laboratories; Bedford, OH, http://www.bedfordlabs.com), vincristine (Oncovin; Eli Lilly and Company; Indianapolis, IN, http://www.lilly.com), and prednisone (Deltasone; Pfizer Pharmaceuticals; New York, NY, http://www.pfizer.com), CHOP, followed by rituximab (Rituxan; Genentech, Inc.; South San Francisco, CA, http://www.gene.com) for patients with incomplete clinical or molecular responses, the CR and molecular response rates were significantly higher in the FM arm, but the PFS and overall survival (OS) rates did not differ between the two arms. However, FM was also significantly less toxic than CHOP. The administration of rituximab following chemotherapy resulted in higher clinical and molecular response rates in both arms. In a separate trial, FM plus dexamethasone (Decadron; Merck and Co., Inc.; Whitehouse Station, NJ, http://www.merck.com), FND, plus concurrent rituximab produced a CR rate of 92%. In a randomized German study, patients with indolent lymphomas received FM plus cyclophosphamide (FCM) or FCM with rituximab. PFS and OS times were significantly better for patients who received combined chemoimmunotherapy. Mitoxantrone-based regimens are highly

    Mantle cell lymphoma (MCL) is an aggressive B-cell non-Hodgkin's lymphoma (NHL). In cancers, tumor suppressive microRNAs may be silenced by DNA hypermethylation. By microRNA profiling of representative EBV-negative MCL cell lines before and after demethylation treatment, miR-155-3p was found significantly restored. Methylation-specific PCR, verified by pyrosequencing, showed complete methylation of miR-155-3p in one MCL cell line (REC-1). 5-aza-2′-deoxycytidine treatment of REC-1 led to demethylation and re-expression of miR-155-3p. Over-expression of miR-155-3p led to increased sub-G1 apoptotic cells and reduced cellular viability, demonstrating its tumor suppressive properties. By luciferase assay, lymphotoxin-beta (LT-β) was validated as a miR-155-3p target. In 31 primary MCL, miR-155-3p was found hypermethylated in 6(19%) cases. To test if methylation of miR-155-3p was MCL-specific, miR-155-3p methylation was tested in an additional 191 B-cell, T-cell and NK-cell NHLs, yielding miR-155-3p methylation in 66(34.6%) including 36(27%) non-MCL B-cell, 24(53%) T-cell and 6(46%) of NK-cell lymphoma. Moreover, in 72 primary NHL samples with RNA, miR-155-3p methylation correlated with miR-155-3p downregulation (p = 0.024), and LT-β upregulation (p = 0.043). Collectively, miR-155-3p is a potential tumor suppressive microRNA hypermethylated in MCL and other NHL subtypes. As miR-155-3p targets LT-β, which is an upstream activator of the non-canonical NF-kB signaling, miR-155-3p methylation is potentially important in lymphomagenesis. PMID:25211095

  7. Improvement of hospital care for patients with non-Hodgkin’s lymphoma: protocol for a cluster randomized controlled trial (PEARL study)

    2013-01-01

    Background Malignant lymphomas constitute a diverse group of cancers of lymphocytes. One well-known disease is Hodgkin’s lymphoma; the others are classified as non-Hodgkin’s lymphoma (NHL). NHLs are the most common hematologic neoplasms in adults worldwide, and in 2012 over 170,000 new cases were estimated in the United States and Europe. In previous studies, several practice gaps in hospital care for patients with NHL have been identified. To decrease this variation in care, the present study aims to perform a problem analysis in which barriers to and facilitators for optimal NHL care will be identified and, based on these findings, to develop (tailored) improvement strategies. Subsequently, we will assess the effectiveness, feasibility and costs of the improvement strategies. Methods/design Barriers and facilitators will be explored using the literature, using interviews and questionnaires among physicians involved in NHL care, and patients diagnosed with NHL. The results will be used to develop a tailored improvement strategy. A cluster randomized controlled trial involving 19 Dutch hospitals will be conducted. Hospitals will be randomized to receive either an improvement strategy tailored to the barriers and facilitators found or, a standard strategy of audit and feedback. The effects of both strategies will be evaluated using previously developed quality indicators. Adherence to the indicators will be measured before and after the intervention period based on medical records from newly diagnosed NHL patients. To study the feasibility of both strategies, a process evaluation will be additionally performed. Data about exposure to the different elements of the strategies will be collected using questionnaires. Economic evaluation from a healthcare perspective will compare the two implementation strategies, where the costs of the implementation strategy and changes in healthcare consumption will be assessed.

    Background Non-Hodgkin’s lymphoma (NHL) has been reported to be associated with autoimmune and pro-inflammatory response, and genetic polymorphisms of candidate genes involved in autoimmune and pro-inflammatory response may influence the susceptibility to NHL. To evaluate the role of such genetic variations in risk of NHL, we conducted a case-control study of 514 NHL patients and 557 cancer-free controls in a Chinese population. Method We used the Taqman assay to genotype six potentially functional single nucleotide polymorphisms (SNPs) in six previously reported inflammation and immune-related genes (TNF rs1799964T>C, LTA rs1800683G>A, IL-10 rs1800872T>G, LEP rs2167270G>A, LEPR rs1327118C>G, TNFAIP8 rs1045241C>T). Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (95% CI). Results We observed a significantly increased risk of NHL associated with the TNFAIP8 rs1045241C>T polymorphism (adjusted OR = 3.03; 95% CI = 1.68–5.45 for TT vs. CC and adjusted OR = 2.03; 95% CI = 1.53–2.69 for CT/TT vs. CC). The risk associated with the T allele was more evident in subgroups of 40–60 year-old, non-smokers or light-smokers (less than 25 pack-years), and subjects with normal weight or overweight. Risk for both B and T cell non-Hodgkin’s lymphoma was elevated for CT/TT genotypes (adjusted OR = 1.95, 95% CI = 1.41–2.70 for B cell NHL and adjusted OR = 2.22, 95% CI = 1.49–3.30 for T cell NHL), particularly for DLBCL (adjusted OR = 2.01, 95%CI = 1.41–2.85) and FL (adjusted OR = 2.53, 95% CI = 1.17–5.45). These risks were not observed for variant genotypes of other five SNPs compared with their common homozygous genotypes. Conclusions The polymorphism of TNFAIP8 rs1045241C>T may contribute to NHL susceptibility in a Chinese population. Further large-scale and well-designed studies are needed to confirm these results.

    Radioimmunotherapy (RIT) is an attractive therapy for non-Hodgkin's lymphoma (NHL) as it allows targeted tumor irradiation which provides a cytotoxic effect significantly greater than that of the immune-mediated effects of a non-radioactive, or 'cold', antibody alone. Anti-CD20 antibodies such as rituximab are ideal for RIT, as not only is it easily iodinated, but the CD20 antigen is found on more than 95% of B-cell NHL. A standard operating procedure (SOP) has been formulated for personalized prospective dosimetry for safe, effective outpatient (131)I-rituximab RIT of NHL. Over five years, experience of treatment of outpatients with (131)I-rituximab was analyzed with respect to critical organ radiation dose in patients and radiation exposure of their carers. This radiation safety methodology has been refined; and offers the potential for safe, practical application to outpatient (131)I-rituximab RIT of lymphoma in general and in developing countries in particular. Given endorsement and sanction of this SOP by local regulatory authorities the personalized dosimetry paradigm will facilitate incorporation of RIT into the routine clinical practice of therapeutic nuclear oncology worldwide.

    Auroras (A and B) are oncogenic serine/threonine kinases that play key roles in the mitotic phase of the eukaryotic cell cycle. Analysis of the leukemia lymphoma molecular profiling project (LLMPP) database indicates Aurora over-expression correlates with poor prognosis. A tissue microarray (TMA) composed of 20 paired mantle cell lymphoma (MCL) patients demonstrated >75% of patients had high levels Aurora expression. Aurora A and B were also found elevated in 13 aggressive B-NHL cell lines. MLN8237, an Aurora inhibitor induced G2/M arrest with polyploidy and abrogated Aurora A and histone-H3 phosphorylation. MLN8237 inhibited aggressive B-NHL cell proliferation at an IC(50) of 10-50 nM and induced apoptosis in a dose- and time-dependent manner. Low dose combinations of MLN8237+docetaxel enhanced apoptosis by ~3-4-fold in cell culture compared to single agents respectively. A mouse xenograft model of MCL demonstrated that MLN8237 (10 or 30 mg/kg) or docetaxel (10mg/kg) alone had modest anti-tumor activity. However, MLN8237 plus docetaxel demonstrated a statistically significant tumor growth inhibition and enhanced survival compared to single agent therapy. Together, our results suggest that MLN8237 plus docetaxel may represent a novel therapeutic strategy that could be evaluated in early phase trials in relapsed/refractory aggressive B-cell NHL.

    Acute liver failure is a rare presentation of hematologic malignancy. Acute on chronic liver failure (ACLF) is a newly recognized clinical entity that describes acute hepatic decompensation in persons with preexisting liver disease. Diffuse large B-cell lymphoma (DLBCL) is an aggressive non-Hodgkin’s lymphoma (NHL) with increasing incidence in older males, females and blacks. However, it has not yet been reported, to present with acute liver failure in patients with preexisting chronic liver disease due to human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection. We describe a case of ACLF as the presenting manifestation of DLBCL in an elderly black man with HIV/HCV co-infection and prior Hodgkin’s disease in remission for three years. The rapidly fatal outcome of this disease is highlighted as is the distinction of ACLF from decompensated cirrhosis. Due to the increased prevalence of HIV/HCV co-infection in the African American 1945 to 1965 birth cohort and the fact that both are risk factors for chronic liver disease and NHL we postulate that the incidence of NHL presenting as ACLF may increase.

    Background Animal studies suggest that lymphomagenesis can be induced by exposure to carcinogenic aromatic and heterocyclic amines found in diet, cigarette smoke, and the environment, but human epidemiologic investigations of these exogenous exposures have yielded conflicting results. As part of our evaluation of the role of aromatic and heterocyclic amines, which are metabolized by N-acetyltransferase (NAT) enzymes, in the etiology of non-Hodgkin lymphoma (NHL), we examined NHL risk in relation to genetic variation in NAT1 and NAT2 and exposure to cigarette smoke and dietary heterocyclic amines and mutagens. Methods We genotyped ten common single nucleotide polymorphisms (SNPs) in NAT1 and NAT2 among 1136 cases and 922 controls from a population-based case–control study in four geographic areas of the US. Relative risk of NHL for NAT1 and NAT2 genotypes, NAT2 acetylation phenotype, and exposure to cigarette smoke and dietary heterocyclic amines and mutagens was estimated using odds ratios (ORs) and 95% confidence intervals (CIs) derived from unconditional logistic regression models. Results We observed increased risk of NHL among individuals with the NAT1*10/*10 genotype compared with individuals with other NAT1 genotypes (OR=1.60, 95% CI 1.04–2.46, p=0.03). We also observed increased NHL risk in a dose-dependent model among NAT2 intermediate- and rapid-acetylators in comparison with slow-acetylators, although only the trend was statistically significant (intermediate: OR=1.18, 95% CI 0.97–1.44, p=0.1; rapid: OR=1.43, 95% CI 0.97–2.14, p=0.07; p for linear trend=0.03). Compared with nonsmokers, NHL risk estimates for current cigarette smoking were increased only among NAT2 intermediate/rapid-acetylators (OR=2.44, 95% CI 1.15–5.20, p=0.02). Conclusions Our data provide evidence that NAT1 and NAT2 genotypes are associated with NHL risk and support a contributory role for carcinogenic aromatic and/or heterocyclic amines in the multi-factorial etiology of

    The objective of this study was to evaluate the health-related quality of life (HRQOL) of lymphoma survivors, to compare it with that of the general population, and to identify its predictors in lymphoma survivors. We enrolled 837 participants (mean age, 54.6 years; mean time since diagnosis, 6.3 years) with a history of Hodgkin's lymphoma (HL) (n = 58) or non-Hodgkin's lymphoma (NHL) (n = 779) who had been treated at any of three Korean hospitals from 1989 through 2010. For controls, we selected 1,000 subjects randomly from a representative Korean population. We administered the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and the Hospital Anxiety and Depression Scale. Overall, the HRQOL in both groups of survivors and the general population were comparable, but we observed clinically meaningful worse social functioning in NHL survivors (p < 0.001) and more severe fatigue in HL survivors (p < 0.001) than in the general population. Analysis of covariance revealed no clinically meaningful difference in HRQOL associated with age or sex. Survivors who received peripheral blood stem cell transplants showed clinically meaningful worse role (p = 0.001) and social (p < 0.001) functioning than those who were treated with first-line chemotherapy alone. In multivariate analyses, fatigue, depression, and financial difficulties emerged as the strongest predictors for almost all subscales of functioning and global quality of life. Interventions for alleviating fatigue, depression, and financial difficulties are needed to enhance the HRQOL of Korean lymphoma survivors. PMID:24947794

    Acalabrutinib (ACP-196) is a second-generation inhibitor of Bruton agammaglobulinemia tyrosine kinase (BTK) with increased target selectivity and potency compared to ibrutinib. In this study, we evaluated acalabrutinib in spontaneously occurring canine lymphoma, a model of B-cell malignancy similar to human diffuse large B-cell lymphoma (DLBCL). First, we demonstrated that acalabrutinib potently inhibited BTK activity and downstream effectors in CLBL1, a canine B-cell lymphoma cell line, and primary canine lymphoma cells. Acalabrutinib also inhibited proliferation in CLBL1 cells. Twenty dogs were enrolled in the clinical trial and treated with acalabrutinib at dosages of 2.5 to 20mg/kg every 12 or 24 hours. Acalabrutinib was generally well tolerated, with adverse events consisting primarily of grade 1 or 2 anorexia, weight loss, vomiting, diarrhea and lethargy. Overall response rate (ORR) was 25% (5/20) with a median progression free survival (PFS) of 22.5 days. Clinical benefit was observed in 30% (6/20) of dogs. These findings suggest that acalabrutinib is safe and exhibits activity in canine B-cell lymphoma patients and support the use of canine lymphoma as a relevant model for human non-Hodgkin lymphoma (NHL).

    Diffuse large B-cell lymphomas (DLBCLs) are defined as neoplasms of large transformed B cells, i.e. with nuclear diameter more than twice that of a normal lymphocyte. These account for 30-40% of all adult non-Hodgkin's lymphomas (NHL). Intraoral lymphomas are relatively rare and often difficult to diagnose in clinical settings. In this case report, we describe a case of primary DLBCL affecting the anterior part of the hard palate of an elderly male patient. DLBCL of anterior part of hard palate is yet to be reported in the English literature, even though DLBCL cases involving the posterior palate have been recorded, thus making the present case to be first of its kind. Emphasis has also been given on the subclassification, differential diagnosis and prognostic antibody factors determining the outcome of DLBCL. PMID:24959047

    Numerous management options are available to patients with advanced-stage or relapsed/refractory indolent non-Hodgkin lymphomas (NHLs). These include observation in patients with low-volume disease, systemic therapy including radioimmunotherapy, and high-dose therapy with stem cell transplant. In selected patients with localized symptomatic disease, local radiation therapy to sites of involvement can offer effective palliation. However, systemic therapy and standard-dose radiation therapy can be associated with significant toxicities. Over the past 15 years, several groups have investigated the role of low-dose radiation therapy--typically 4 Gy in two fractions--to an involved-field as an option for palliation in patients with NHL. Overall response rates of more than 80% have been consistently reported with local control maintained for 2 years. In this review, we outline the clinical experience with this approach in NHL of various histologies. PMID:19883306

    Acquired generalized lipodystrophy (AGL) is a rare disease thought to result from autoimmune destruction of adipose tissue. Peripheral T-cell lymphoma (PTCL) has been reported in two AGL patients. We report five additional cases of lymphoma in AGL, and analyze the role of underlying autoimmunity and recombinant human leptin (metreleptin) replacement in lymphoma development. Three patients developed lymphoma during metreleptin treatment (two PTCL and one ALK-positive anaplastic large cell lymphoma), and two developed lymphomas (mycosis fungoides and Burkitt lymphoma) without metreleptin. AGL is associated with high risk for lymphoma, especially PTCL. Autoimmunity likely contributes to this risk. Lymphoma developed with or without metreleptin, suggesting metreleptin does not directly cause lymphoma development; a theoretical role of metreleptin in lymphoma progression remains possible. For most patients with AGL and severe metabolic complications, the proven benefits of metreleptin on metabolic disease will likely outweigh theoretical risks of metreleptin in lymphoma development or progression.

    Involvement of the lower urinary tract by advanced non-Hodgkin’s lymphoma (NHL) has been reported in up to 13% of cases, but primary NHL of the urinary bladder is very rare. A 35-year-old man was admitted to our hospital with a chief complaint of gross hematuria with left flank pain on April 12, 2001. Cystoscopy revealed an edematous broad-based mass on the left lateral wall of the bladder, and transurethral biopsy showed NHL, diffuse large B-cell type. Abdomino-pelvic CT scan demonstrated left-side hydronephrosis and hydroureter with left proximal ureter infiltration and thickening of the left lateral wall of the bladder with perivesical fat infiltration without lymph node enlargement. Full-scale staging work-up revealed the bone marrow as the solely involved site. The lesions of the bladder and left urinary tract were nearly completely regressed after two cycles of systemic cyclophosphamide, doxorubicin, vincristine and predinisone (CHOP) chemotherapy with simultaneous restoration of urinary function.

    The relative distribution of non-Hodgkin lymphoma (NHL) subtypes differs markedly around the world. The aim of this study was to report this distribution in Algeria. A panel of four hematopathologists classified 197 consecutive cases according to the World Health Organization classification, including 87.3% B-cell and 12.7% T- or natural killer (NK)-cell NHLs. This series was compared with similar cohorts from Western Europe (WEU) and North America (NA). Algeria had a significantly higher frequency of diffuse large B-cell lymphoma (DLBCL: 52.8%) and a lower frequency of follicular lymphoma (FL: 13.2%) compared with WEU (DLBCL: 32.2%; FL: 20.0%) and NA (DLBCL: 29.3%; FL: 33.6%). The frequency of mantle cell lymphoma was lower in Algeria (2.5%) compared with WEU (8.3%). Smaller differences were also found among the NK/T-cell lymphomas. In conclusion, we found important differences between Algeria and Western countries, and further epidemiologic studies are needed to explain these differences. PMID:25012941

    bcl-2 expression is associated with the expression of the multidrug resistance molecule (p-gp) and the resistance of leukaemia cells to the induction of apoptosis. The activity of p-gp is the main mechanism of resistance of leukaemia cells to chemotherapy. This study assessed the induction of apoptosis of acute lymphoblastic leukaemia (ALL) and non-Hodgkin's lymphoma (NHL) blastic cells following in vitro treatment with dexamethasone (DXM), vincristine (VCR), and tumour necrosis factor (TNF) in relation to the expression of bcl-2 and p-gp. Common ALL (cALL; n = 24 patients), common ALL with co-expression of myeloid antigens (cALL + My; n = 9), ALL-T (n = 9), and NHL [n = 6 (T type, n = 2; B type, n = 4)] were included. The expression of bcl-2 and p-gp and apoptosis were assayed by flow cytometry. Spontaneous apoptosis was low (< 5%) in cALL and ALL-T and higher (> 8%) in NHL and cALL + My. A high frequency of bcl-2 expression was noted in cALL and cALL + My. A high frequency of p-gp expression was observed in cALL + My, ALL-T, and NHL. There was a reverse association between bcl-2 expression and spontaneous apoptosis. DXM-induced apoptosis was observed in 52.63%, TNF-induced in 42.85%, VCR-induced in 36.36%, and GM-CSF-induced in 33.3% of leukaemia and lymphoma cases. DXM and GM-CSF-driven apoptosis was reversibly associated with bcl-2-expression (bcl-2-dependent mechanism). VCR and TNF-driven apoptosis was not associated with bcl-2 expression, suggesting a different, bcl-2-independent, mechanism(s) of its induction. The in vitro induction of apoptosis was not associated with expression of p-gp. PMID:11855781

    Background Epidemiologic studies of companion animals offer an important opportunity to identify risk factors for cancers in animals and humans. Canine malignant lymphoma (CML) has been established as a model for non-Hodgkin’s lymphoma (NHL). Previous studies have suggested that exposure to environmental chemicals may relate to development of CML. Methods We assessed the relation of exposure to flea and tick control products and lawn-care products and risk of CML in a case-control study of dogs presented to a tertiary-care veterinary hospital (2000–2006). Cases were 263 dogs with biopsy-confirmed CML. Controls included 240 dogs with benign tumors and 230 dogs undergoing surgeries unrelated to cancer. Dog owners completed a 10-page questionnaire measuring demographic, environmental, and medical factors. Results After adjustment for age, weight, and other factors, use of specific lawn care products was associated with greater risk of CML. Specifically, the use of professionally applied pesticides was associated with a significant 70% higher risk of CML (odds ratio(OR)=1.7; 95% confidence interval (CI)=1.1–2.7). Risk was also higher in those reporting use of self-applied insect growth regulators (OR = 2.7; 95% CI=1.1–6.8). The use of flea and tick control products was unrelated to risk of CML. Conclusions Results suggest that use of some lawn care chemicals may increase the risk of CML. Additional analyses are needed to evaluate whether specific chemicals in these products may be related to risk of CML, and perhaps to human NHL as well. PMID:22222006

    OBJECTIVE: This study provides the clinical pathological characteristics of 1301 cases of pediatric/adolescent lymphomas in patients from different geographic regions of Brazil. METHODS: A retrospective analyses of diagnosed pediatric lymphoma cases in a 10‐year period was performed. We believe that it represents the largest series of pediatric lymphomas presented from Brazil. RESULTS: Non‐Hodgkin lymphomas represented 68% of the cases, including those of precursor (36%) and mature (64%) cell origin. Mature cell lymphomas comprised 81% of the B‐cell phenotype and 19% of the T‐cell phenotype. Hodgkin lymphomas represented 32% of all cases, including 87% of the classical type and 13% of nodular lymphocyte predominant type. The geographic distribution showed 38.4% of the cases in the Southeast region, 28.7% in the Northeast, 16.1% in the South, 8.8% in the North, and 8% in the Central‐west region. The distribution by age groups was 15–18 years old, 33%; 11–14 years old, 26%; 6–10 years old, 24%; and 6 years old or younger, 17%. Among mature B‐cell lymphomas, most of the cases were Burkitt lymphomas (65%), followed by diffuse large B‐cell lymphomas (24%). In the mature T‐cell group, anaplastic large cell lymphoma, ALK‐positive was the most prevalent (57%), followed by peripheral T‐cell lymphoma, then not otherwise specified (25%). In the group of classic Hodgkin lymphomas, the main histological subtype was nodular sclerosis (76%). Nodular lymphocyte predominance occurred more frequently than in other series. CONCLUSION: Some of the results found in this study may reflect the heterogeneous socioeconomical status and environmental factors of the Brazilian population in different regions. PMID:21340214

    Chemotherapy-induced nausea and vomiting (CINV) is a serious problem for cancer patients receiving chemotherapy. The CHOP regimen is the standard treatment for non-Hodgkin's lymphoma (NHL) and is categorized as highly or moderately emetogenic in the CINV guidelines. The efficacy of oral 5-HT3 receptor antagonists is equivalent to that of the intravenous form in patients with solid tumors, but there is no clear comparative data for the use of these agents NHL patients receiving CHOP. We analyzed retrospective CINV data from medical records of 72 NHL patients who received CHOP or rituximab-combined CHOP therapy (R-CHOP). All patients received 5-HT3 receptor antagonists alone for prevention of CINV; 39 of the patients received an intravenous form (mostly granisetron) and 33 an oral form (all ramosetron). Complete response (CR: defined as no vomiting and no rescue therapy) was observed in 58 of 72 patients (80.6 %) overall (0-120 h post-CHOP). The CR rate was not statistically different in patients treated with oral or intravenous 5-HT3 receptor antagonists (82.1 vs 78.8 %, P = 0.77). These findings suggest that oral 5-HT3 receptor antagonists represent a good alternative to intravenous forms in NHL receiving CHOP/R-CHOP chemotherapy. Further studies are needed to identify the optimal anti-emetic supportive therapy for NHL. PMID:27312042

    To compare the clinical outcomes of older (age ≥ 55 years) non-Hodgkin’s lymphoma (NHL) patients with younger NHL patients (< 55 years) receiving autologous hematopoietic cell transplantation (HCT) while adjusting for patient-, disease-, and treatment-related variables. We compared autologous HCT outcomes in 805 NHL patients age ≥ 55 years to 1,949 NHL patients < 55 years during the years 1990–2000 using data reported to the Center for International Blood and Marrow Transplant Research (CIBMTR). In multivariate analysis, older patients with aggressive histologies were 1.86 times [95% confidence interval (CI) 1.43–2.43, p<0.001] more likely than younger patients to experience treatment-related mortality. Relative death risks were 1.33 times (CI 1.04–1.71, p=0.024) and 1.50 times (CI 1.33–169, p<0.001) higher in older compared to younger patients with follicular grade I/II and aggressive histologies, respectively. Autologous HCT in older NHL patients is feasible but most disease-related outcomes are statistically inferior to younger patients. Studies addressing supportive care particular to older patients who are most likely to benefit from this approach are recommended. PMID:19041053

    Non-Hodgkin lymphoma (NHL) has been linked to several agricultural exposures, including some commonly used pesticides. Although there is a significant body of literature examining the effects of exposure to individual pesticides on NHL, the impact of exposure to multiple pesticides or specific pesticide combinations has not been explored in depth. Data from a six-province Canadian case-control study conducted between 1991 and 1994 were analyzed to investigate the relationship between NHL, the total number of pesticides used and some common pesticide combinations. Cases (n = 513) were identified through hospital records and provincial cancer registries and controls (n = 1,506), frequency matched to cases by age and province of residence, were obtained through provincial health records, telephone listings, or voter lists. In multiple logistic regression analyses, risk of NHL increased with the number of pesticides used. Similar results were obtained in analyses restricted to herbicides, insecticides and several pesticide classes. Odds ratios increased further when only ‘potentially carcinogenic’ pesticides were considered (OR[one pesticide] = 1.30, 95% CI = 0.90–1.88; OR[two to four] = 1.54, CI = 1.11–2.12; OR[five or more] = 1.94, CI = 1.17–3.23). Elevated risks were also found among those reporting use of malathion in combination with several other pesticides. These analyses support and extend previous findings that the risk of NHL increases with the number of pesticides used and some pesticide combinations. PMID:21776232

    To evaluate the clinical benefit of the prophylactic use of urate oxidase in children with non-Hodgkin's lymphoma (NHL), we analyzed the incidence and complications of tumor lysis syndrome (TLS) in children with B-cell acute lymphoblastic leukemia (B-ALL) or stage III/IV Burkitt's lymphoma and a lactate dehydrogenase (LDH) level > or =500 U/l before and after the introduction of a protocol amendment to use urate oxidase for the prophylaxis of TLS. Data from 1791 children with NHL enrolled in the two subsequent multicenter studies NHL-BFM 90 and 95 were evaluated. The presence of the side effects TLS, anuria, sepsis, and other complications during the first 2 weeks after admission were registered. Until March 1996, no urate oxidase was used (period 1). From November 1997 all children with B-ALL or stage III and IV B-NHL and LDH > or =500 U/l should receive urate oxidase prophylactically (period 3). In between (period 2), urate oxidase was given in a minority of hospitals therapeutically. Initial chemotherapy was identical. Altogether, 78 children (4.4%) developed a TLS. Patients with B-ALL had the highest risk to develop a TLS (26.4%) followed by B-ALL/Burkitt's lymphoma and a LDH > or =500 U/l (14.9%). In period 1, 16.1% and 9.2% of the latter children developed a TLS or anuria, respectively, compared to 12.3% and 6.2% in period 3 ( p=NS). The incidence of sepsis remained unchanged (5.0% vs 4.6%). In children with B-ALL the differences in the incidence of TLS and anuria between period 3 and period 1 were more pronounced, reaching significance for anuria (15.4% vs 3.8%, p=0.03). Our results suggest that patients with the highest risk to develop a TLS might benefit from the prophylactic use of urate oxidase. PMID:12634948

    No effective salvage regimen has been defined for patients with AIDS-related non-Hodgkin's lymphoma (AIDS-NHL) who do not respond to first-line chemotherapy that contains anthracycline. Combined dexamethasone, cytosine arabinoside, and cisplatin (DHAP) and etoposide, methylprednisolone, cytosine arabinoside, and cisplatin (ESHAP) have shown good response rates in HIV-negative patients with relapsed lymphomas. We retrospectively analyzed patients with refractory or relapsed AIDS-NHL who had been treated with either DHAP or ESHAP to evaluate the feasibility and efficacy of these regimens. Twenty-six patients with refractory or relapsed AIDS-NHL were treated between 1990 and 1999 either with DHAP ( n = 13) or with ESHAP ( n = 13). Only 1 patient from each group (8%) had achieved complete remission with any previous therapy, and most had progressive disease after the regimen immediately preceding DHAP or ESHAP. In the ESHAP group, 4 patients (31%) achieved complete remission (CR) and 3 patients (23%) attained partial remission (PR) for an overall response rate of 54%. The median survival was 7.1 months (range, 1-58.9+ months) from the time ESHAP was begun. Among the 3 patients with primary refractory lymphoma, there was 1 CR, 1 PR, and one patient with stable disease. In contrast, only 1 PR (7%) was observed with DHAP; the median survival was 3 months. Myelosuppression was the most significant toxicity with grade 4 neutropenia occurring in all who received ESHAP and in 54% of patients treated with DHAP. Neutropenic fever occurred in 8 (62%) ESHAP-treated and 6 (46%) DHAP-treated patients. Although hematologic toxicity is profound, ESHAP appears to be an active salvage regimen for patients with relapsed or refractory AIDS-NHL. PMID:11744828

    Understanding of the lymphoma tumor microenvironment is poised to expand in the era of next-generation sequencing studies of the tumor cells themselves. Successful therapies of the future will rely on deeper appreciation of the interactions between elements of the microenvironment. Although the phenotypic, cytogenetic, and molecular characterization of tumor cells in lymphomas has progressed faster than most other solid organ tumors, concrete advancements in understanding the lymphoma microenvironment have been fewer. This article explores the composition of the lymphoma tumor microenvironment; its role in immune surveillance, evasion, and drug resistance; and its potential role in the development of targeted therapies.

    Peripheral T-cell lymphomas (PTCLs) comprise a rare and heterogeneous subset of non-Hodgkin’s lymphomas (NHLs) that arise from post-thymic T-cells or natural killer (NK)-cells at nodal or extranodal sites. Worldwide, PTCLs represent approximately 12% of all NHLs and the 2008 World Health Organization (WHO) classification includes over 20 biologically and clinically distinct T/NK-cell neoplasms that differ significantly in presentation, pathology, and response to therapy. Because of the rarity and heterogeneity of these diseases, large clinical trials have not been conducted and optimal therapy is not well defined. Most subtypes are treated with similar combination chemotherapy regimens as used for aggressive B-cell NHL, but with poorer outcomes. New treatment combinations and novel agents are currently being explored for PTCLs and this review highlights a number of options that appear promising. PMID:22287871

    Cold agglutinin disease (CAD) is an autoimmune hemolytic anemia (AIHA) generally caused by IgM autoantibodies which exhibit maximal reactivity at 4°C. CAD can be idiopathic or secondary to some diseases and/or conditions. Only a minority of cases of secondary AIHA in non-Hodgkin's lymphoma (NHL) are associated with cold antibodies. Diffuse large B cell lymphoma (DLBCL) is the most common subtype of NHLs with a proportion of nearly 30% of all adult cases. 40% of patients with DLBCL have an extranodal disease or at least disease initially confined to extranodal sites. The most common extranodal site is the gastrointestinal tract. We present a patient with primary gastrointestinal DLBCL who presented with CAD and was treated with a CHOP-Rituximab regimen.

    Peripheral T-cell lymphomas (PTCLs) represent a relatively uncommon heterogeneous group of non-Hodgkin's lymphomas (NHLs) with an aggressive clinical course and poor prognosis. Anthracycline-based multiagent chemotherapy with or without radiation therapy followed by first-line consolidation with high-dose therapy followed by autologous stem cell rescue (HDT/ASCR) is the standard approach to most of the patients with newly diagnosed PTCL. Relapsed or refractory disease is managed with second-line systemic therapy followed by HDT/ASCR or allogeneic stem cell transplant, based on the patient's eligibility for transplant. In recent years, several newer agents have shown significant activity in patients with relapsed or refractory disease across all 4 subtypes of PTCL. These NCCN Guideline Insights highlight the important updates to the NCCN Guidelines for NHL, specific to the management of patients with relapsed or refractory PTCL. PMID:27587620

    The risk of second cancers (SCs) was assessed in 744 patients with Hodgkin's disease (HD) admitted to The Netherlands Cancer Institute from 1966 to 1983. Sixty-nine SCs were observed one month or more after start of first treatment. These included 14 cases of lung cancer, nine cases of non-Hodgkin's lymphoma (NHL), 16 cases of leukemia, and six cases of the myelodysplastic syndrome (MDS). The median interval between the diagnosis of HD and that of second lung cancer, NHL, and leukemia was 8.1, 13.3, and 5.7 years, respectively. The overall relative risks (RR) (observed/expected (O/E) ratios) of developing lung cancer, NHL, and leukemia were 4.9 (95% confidence limit (CL), 2.7 to 8.2), 31.0 (95% CL, 14.2 to 58.9) and 45.7 (95% CL, 26.1 to 74.2), respectively. At 15 years the cumulative risk of developing an SC amounted to 20.6% +/- 2.9%. The 15-year estimates of lung cancer, NHL, and leukemia were 6.2% +/- 1.9%, 5.9% +/- 2.1% and 6.3% +/- 1.7%, respectively. Increased lung cancer risk following HD has not frequently been clearly demonstrated before; that we were able to demonstrate such risk may be due to the completeness of follow-up over long periods that could be achieved in this study. Excess lung cancer risk was only noted in treatment regimens with radiotherapy (RT); also, all lung cancers arose in irradiation fields. Excess risk of leukemia was only found in treatment regimens involving chemotherapy (CT). For NHL, combined modality treatment was shown to be the most important risk factor. Risk of lung cancer and NHL increased with time since diagnosis. A time-dependent covariate analysis (Cox model) performed on leukemia and MDS showed an increasing risk with intensity of CT, age (greater than 40 years), and a splenectomy.

    Combination chemotherapy regimen incorporating CD20 antibodies are commonly used in the treatment of CD20-positive non-Hodgkin's lymphoma (NHL). Fludarabine phosphate (F-araAMP), cyclophosphamide, and CD20 antibodies (Rituximab) constitute the FCR regimen for treating selected NHL, including aggressive mantle cell lymphoma (MCL). As an alternative to the CD20 antibody, we generated a CD20-targeted measles virus (MV)-based vector. This vector was also armed with the prodrug convertase purine nucleoside phosphorylase (PNP) that locally converts the active metabolite of F-araAMP to a highly diffusible substance capable of efficiently killing bystander cells. We showed in infected cells that early prodrug administration controls vector spread, whereas late administration enhances cell killing. Control of spread by early prodrug administration was also shown in an animal model: F-araAMP protected genetically modified mice susceptible to MV infection from a potentially lethal intracerebral challenge. Enhanced oncolytic potency after extensive infection was shown in a Burkitt's lymphoma xenograft model (Raji cells): After systemic vector inoculation, prodrug administration enhanced the therapeutic effect synergistically. In a MCL xenograft model (Granta 519 cells), intratumoral (i.t.) vector administration alone had high oncolytic efficacy: All mice experienced complete but temporary tumor regression, and survival was two to four times longer than that of untreated mice. Cells from MCL patients were shown to be sensitive to infection. Thus, synergy of F-araAMP with a PNP-armed and CD20-targeted MV was shown in one lymphoma therapy model after systemic vector inoculation. PMID:18006839

    Radioimmunodetection (RAID) with 99m technetium labelled B cell lymphoma monoclonal antibody (MAb) (IMMU-LL2 Fab`, Immunomedics, Inc., Morris Plains, N.J.) was investigated in 8 patients (5 female and 3 male; age range 20-72 years) with histologically proven non-Hodgkin`s lymphoma (NHL). Of the 8 lymphomas, 5 were intermediate grade and 3 low grade. Whole body images with multiple planar views were obtained at 30 min, 4-6 and 24 hours after the I.V. injection of 1 mg LL2-Fab` labelled with 20-25 mCi (740-925 MBq) {sup 99}Tc. SPECT of chest or abdomen was performed at 5-8 hours after injection in all patients. No adverse reactions were observed in any patient after MAb infusion and no appreciable changes were seen in the blood counts, renal and liver function tests. A total of 17 of 18 (94.4%) lymphoma lesions were detected by RAID. All the tumor localizations were confirmed by clinical examination and with other imaging techniques, such as CT scan, MRI or gallium scan. In this series of patients no false positive results were noted and only 1 false negative resulted in a patient who had a mediastinal bulky disease. As regard the biodistribution of the immunoreagent we can make the following conclusions: (1) no appreciable bone marrow activity was seen, (2) splenic targeting was demonstrated in all patients, (3) tumor-to-non tumor ratios ranged from 1.2 to 2.8 as measured by ROI technique, (4) no difference of uptake was noted for different tumor grades. The images performed 24 hours after injection did not detect new lesions, but areas of doubtful uptake were seen as positive focal areas in the delayed scan. In these preliminary results the LL2-Fab` MAb seems to be useful for detection, staging and follow up of NHL patients.

    Purpose: Low-dose radiation has become increasingly used in the management of indolent non-Hodgkin lymphoma (NHL), but has not been studied specifically for cases of ocular adnexal involvement. The objective of this study is to investigate the effectiveness of low-dose radiation in the treatment of NHL of the ocular adnexa. Methods and Materials: We reviewed the records of 20 NHL patients with 27 sites of ocular adnexal involvement treated with low-dose radiation consisting of 2 successive fractions of 2 Gy at our institution between 2005 and 2011. The primary endpoint of this study is freedom from local relapse (FFLR). Results: At a median follow-up time of 26 months (range 7-92), the overall response rate for the 27 treated sites was 96%, with a complete response (CR) rate of 85% (n=23) and a partial response rate of 11% (n=3). Among all treated sites with CR, the 2-year FFLR was 100%, with no in-treatment field relapses. The 2-year freedom from regional relapse rate was 96% with 1 case of relapse within the ipsilateral orbit (outside of the treatment field). This patient underwent additional treatment with low-dose radiation of 4 Gy to the area of relapse achieving a CR and no evidence of disease at an additional 42 months of follow-up. Orbital radiation was well tolerated with only mild acute side effects (dry eye, conjunctivitis, transient periorbital edema) in 30% of treated sites without any reports of long-term toxicity. Conclusions: Low-dose radiation with 2 Gy × 2 is effective and well tolerated in the treatment of indolent NHL of the ocular adnexa with high response rates and durable local control with the option of reirradiation in the case of locoregional relapse.

    The complex process of phloem sugar transport involves symplasmic and apoplasmic events. We characterized Arabidopsis thaliana lines ectopically expressing a phloem-specific gene encoding NDR1/HIN1-like26 (NHL26), a putative membrane protein. NHL26 overexpressor plants grew more slowly than wild-type plants, accumulated high levels of carbohydrates in mature leaves, and had a higher shoot biomass, contrasting with slower root growth and a lower seed yield. Similar effects were observed when NHL26 was overexpressed in companion cells, under the control of a companion cell–specific promoter. The soluble sugar content of the phloem sap and sink organs was lower than that in the wild type, providing evidence of a sugar export defect. This was confirmed in a phloem-export assay with the symplastic tracer carboxyfluorescein diacetate. Leaf sugar accumulation was accompanied by higher organic acid, amino acid, and protein contents, whereas analysis of the metabolite profile of phloem sap exudate revealed no change in amino acid or organic acid content, indicating a specific effect on sugar export. NHL26 was found to be located in the phloem plasmodesmata and the endoplasmic reticulum. These findings reveal that NHL26 accumulation affects either the permeability of plasmodesmata or sugar signaling in companion cells, with a specific effect on sugar export. PMID:23715470

    The International Diabetes Federation Diabetes Atlas estimates a staggering 590 million people affected with diabetes mellitus (DM) within the next two decades globally, of which Type 2 DM will constitute more than 90%. The associated insulin resistance, hyperinsulinemia, and hyperglycemia pose a further significant risk for developing diverse malignant neoplasms. Diabetes and malignancy are multifactorial heterogeneous diseases. The immune dysfunction secondary to Type 2 diabetes also reactivates latent infections with high morbidity and mortality rates. Epstein-Barr virus (EBV), a ubiquitous human herpes virus-4, is an oncogenic virus; its recrudescence in the immunocompromised condition activates the expression of EBV latency genes, thus immortalizing the infected cell and giving rise to lymphomas and carcinomas. Extranodal natural killer/T-cell lymphoma (ENKTCL), common in South-East Asia and Latin America; is a belligerent type of non-Hodgkin lymphoma (NHL) almost invariably associated with EBV. An analysis of articles sourced from the PubMed database and Google Scholar web resource until February 2014, suggests an increasing incidence of NHL in Asia/India and of ENKTCL in India, over the last few decades. This article reviews the epidemiological evidence linking various neoplasms with Type 2 DM and prognosticates the emergence of ENKTCL as a common lymphoreticular malignancy secondary to Type 2 diabetes, in the Indian population in the next few decades.

    CD20, a membrane protein highly expressed on most B-cell lymphomas, is an effective target demonstrated in clinical practice for treating B-cell non-Hodgkin's lymphoma (NHL). Rituximab is a monoclonal antibody against CD20. In this work, we applied atomic force microscopy (AFM) to map the nanoscale distribution of CD20 molecules on the surface of cancer cells from clinical B-cell NHL patients under the assistance of ROR1 fluorescence recognition (ROR1 is a specific cell surface marker exclusively expressed on cancer cells). First, the ROR1 fluorescence labeling experiments showed that ROR1 was expressed on cancer cells from B-cell lymphoma patients, but not on normal cells from healthy volunteers. Next, under the guidance of ROR1 fluorescence, the rituximab-conjugated AFM tips were moved to cancer cells to image the cellular morphologies and detect the CD20-rituximab interactions on the cell surfaces. The distribution maps of CD20 on cancer cells were constructed by obtaining arrays of (16×16) force curves in local areas (500×500 nm{sup 2}) on the cell surfaces. The experimental results provide a new approach to directly investigate the nanoscale distribution of target protein on single clinical cancer cells. - Highlights: • Cancer cells were recognized from healthy cells by ROR1 fluorescence labeling. • The nanoscale distribution of CD20 on cancer cells was characterized. • The distribution of CD20 was non-uniform on the surface of cancer cells.

    Burkitt lymphoma (BL) is a highly aggressive non-Hodgkin lymphoma (NHL) with endemic, sporadic and immunodeficiency-associated clinical variants composed of monomorphic medium-size B-cells with a high proliferation rate and a translocation involving the C-MYC locus. Classically the immunophenotype of Burkitt lymphoma has been considered to be of germinal center type. In most reports, all cases of BL are reported to be MUM1 negative. MUM1 expression is seen in plasma cells and in a small fraction of B cells located in the light zone of germinal centers corresponding to the final step of intra-germinal center (GC) B-cell differentiation, and in activated T-cells. Therefore, MUM1 expression may denote the final step of intra-GC B-cell differentiation at centrocyte stage, as well as the subsequent steps of B-cell maturation towards plasma cells. Unlike most normal GC B-cells, in which the expression of MUM1 and bcl-6 are mutually exclusive, the tumor cells in approximately 50% of MUM1 positive DLBCL show co-expression of bcl-6, suggesting that the expression of these proteins may be deregulated. In one of the few studies in the literature, 25 BL-cases, including 19 associated with HIV; two of these cases showed occasional MUM1+ cells, less than the 20% cut-off for positivity. We studied 222 cases of well-characterized Burkitt lymphoma with the classic phenotype and C-MYC translocation, and found 90 cases (40.5%) with MUM1 nuclear expression suggesting a late germinal center stage of differentiation.

    Corroborating evidence related to the role of aberrations on one-carbon metabolism (OCM) genes has been inconsistent. We evaluated the association between polymorphisms in 12 single nucleotide polymorphisms (SNPs) in 8 OCM genes (CBS, FPGS, FTHFD, MTRR, SHMT1, SLC19A1, TCN1, and TYMS), and non-Hodgkin lymphoma (NHL) risk in a multi-ethnic population which includes Malay, Chinese and Indian ethnic subgroups.

Our results of the pooled subjects showed a significantly enhanced NHL risk for CBS Ex9 + 33C > T (T versus C: OR 1.55, 95% CI 1.22-1.96, P = 0.0003), CBS Ex18-319G > A (A versus G: OR 1.15, 95% CI 1.14-1.83; P = 0.002), SHMT1 Ex12 + 236 T > C (T versus C: OR 1.44, 95% CI 1.15-1.81, P = 0.002), and TYMS Ex8 + 157C > T (T versus C: OR 1.29, 95% CI 1.06-1.57, P = 0.01). Haplotype analysis for CBS SNPs showed a significantly decreased risk of NHL in subjects with haplotype CG (OR 0.69, 95% CI 0.56-0.86, P = <0.001). The GG haplotype for the FTHFD SNPs showed a significant increased risk of NHL (OR 1.40, 95% CI 1.12-1.76, P = 0.002). For the TYMS gene, haplotype CAT at TYMS (OR 0.67, 95% CI 0.49-0.90, P = 0.007) was associated with decreased risk of NHL, while haplotype TAC (OR 1.29, 95% CI 1.05-1.58, P = 0.01) was found to confer increased risk of NHL. Our study suggests that variation in several OCM genes (CBS, FTHFD, SHMT1, TCN1, and TYMS) may influence susceptibility to NHL. PMID:25384508

    Src kinases are involved in multiple cellular contexts such as proliferation, adhesion, tumor invasiveness, angiogenesis, cell cycle control and apoptosis. We here demonstrate that three newly developed dual selective Src/Abl kinase inhibitors (SrcK-I) (AZM559756, AZD0530 and AZD0424) are able to induce apoptosis and cell cycle arrest in BCR-ABL, c-KIT and platelet-derived growth factor-negative lymphoma cell lines. Treatment of DOHH-2, WSU-NHL, Raji, Karpas-299, HUT78 and Jurkat cells with SrcK-I revealed that the tested substances were effective on these parameters in the cell lines DOHH-2 and WSU-NHL, whereas the other tested cell lines remained unaffected. Phosphorylation of Lyn and in particular Lck were affected most heavily by treatment with the SrcK-I. Extrinsic as well as intrinsic apoptosis pathways were activated and elicited unique expressional patterns of apoptosis-relevant proteins such as downregulation of survivin, Bcl-XL and c-FLIP. Protein levels of c-abl were downregulated and Akt phosphorylation was decreased by treatment with SrcK-I. Basal expression levels of c-Myc were notably lower in sensitive cell lines as compared with nonsensitive cell lines, possibly providing an explanation for sensitivity versus resistance against these novel substances. This study provides the first basis for establishing novel SrcK-I as weapons in the arsenal against lymphoma cells. PMID:17704648

    Relapse continues to be the primary cause of treatment failure in patients with non-Hodgkin's lymphomas (NHL) undergoing high-dose therapy and autologous stem cell transplantation. The anti-CD20 radioimmunoconjugates, Y-90 ibritumomab tiuxetan (Zevalin; Biogen Idec, Inc., Cambridge, MA, USA) and I-131 tositumomab (Bexxar; Corixa, Seattle, WA; and Glaxo Smith Kline; Philadelphia, PA, USA) have been associated with high response rates, durable remissions and limited toxicity apart from myelosuppression, making them ideal candidates for use in autotransplantation. Tested first as single agents in relapsed patients with indolent and transformed NHL, and then at much higher doses with stem cell support, these agents have now been combined with high-dose chemotherapy prior to autologous stem cell transplant. Radioimmunoconjugates have been used to replace total body irradiation (TBI) in some studies and to augment standard chemotherapy regimens in others. Thus far the results are promising, with combinations of radioimmunoconjugates and chemotherapy producing long-lasting responses in high-risk patients with no more toxicity than that caused by standard conditioning regimens. These results are notable in light of the fact that the dose of radiation delivered to the tumor is 10-fold higher than the dose achievable with TBI. Whether this increase in radiation dose to the targeted lymphoma translates into more durable remissions and an improvement in overall survival requires further investigation. PMID:16434379

    Diffuse large B-cell lymphoma (DLBCL), an aggressive non-Hodgkin lymphoma (NHL), is the most-common subtype of NHL. DLBCL can be classified into at least 3 major immunologically distinct types, which contributes to considerable variation in disease prognosis and response to treatment. DLBCL potentially is curable, even when diagnosed at advanced stages. The current standard of care for most patients with untreated or relapsed/refractory DLBCL is chemoimmunotherapy containing rituximab, an anti-CD20 monoclonal antibody. With advanced understanding of the molecular mechanisms involved in the pathogenesis of DLBCL and specific signaling pathways that are activated in different subtypes, potential new therapeutic targets have been identified, some of which are at the late stages of clinical development. This review summarizes the critical role of rituximab in the current standard of care treatment for DLBCL and discusses why rituximab is likely to remain an important component of treatment options for DLBCL in the foreseeable future. In addition, current and emerging therapeutic agents, including potential benefits of rituximab biosimilars, for patients with DLBCL are discussed. The advent of rituximab biosimilars may facilitate accessibility of rituximab-based chemotherapies to patients with DLBCL and has potential cost-saving benefits for healthcare systems globally.

    Although the anti-CD20 antibody Rituximab has revolutionized the treatment of Non-Hodgkin Lymphoma (NHL), resistance to treatment still existed. Thus, strategies for suppressing Rituximab-resistant NHLs are urgently needed. Here, an anti-CD20 nanocluster (ACNC) is successfully constructed from its type I and type II mAb (Rituximab and 11B8). These distinct anti-CD20 mAbs are mass grafted to a short chain polymer (polyethylenimine). Compared with parental Rituximab and 11B8, the ACNC had a reduced “off-rate”. Importantly, ACNC efficiently inhibited Rituximab-resistant lymphomas in both disseminated and localized human NHL xenograft models. Further results revealed that ACNC is significantly potent in inducing caspase-dependent apoptosis and lysosome-mediated programmed cell death (PCD). This may help explain why ACNC is effective in suppressing rituximab-resistant lymphoma while Rituximab and 11B8 are not. Additionally, ACNC experienced low clearance from peripheral blood and high intratumor accumulation. This improved pharmacokinetics is attributed to the antibody-antigen reaction (active targeting) and enhanced permeability and retention (ERP) effect (passive targeting). This study suggested that ACNC might be a promising therapeutic agent for treatment of rituximab-resistant lymphomas. PMID:26284588

    The CD20 cell surface antigen is expressed at high levels by over 90% of B cell non-Hodgkin lymphomas (NHL), and is the target of the anti-CD20 monoclonal antibody rituximab. To provide more sensitive, tumor-specific positron emission tomography (PET) imaging of NHL, we sought to develop PET imaging agents targeting CD20. Methods Two recombinant anti-CD20 rituximab fragments, a minibody (scFv-CH3 dimer, 80 kDa) and a modified scFv-Fc fragment (105 kDa), designed to clear rapidly, were generated. Both fragments were radiolabeled with 124I, and the minibody was additionally radiometal labeled with 64Cu following conjugation to 1,4,7,10-tetraazacyclododecane-N,N’,N’’,N’’’-tetraacetic acid (DOTA). The radioiodinated fragments and the radiometal labeled minibody were evaluated in mice as microPET imaging agents for in vivo imaging of human CD20-expressing lymphomas. Results Rapid and specific localization to CD20-positive tumors was observed with the radioiodinated fragments. However, their tumor uptakes and blood activities differed, resulting in different levels of contrast in the images. The best candidate was the minibody, with superior uptake (2-fold higher than the scFv-Fc) in CD20-positive tumor and low uptake in CD20-negative tumor. Positive tumor to negative tumor ratios were 7.0(±3.1) and 3.9(±0.7) for the minibody and scFv-Fc, respectively at 21 hours. About a 5-fold lower ratio was achieved with the 64Cu-DOTA-minibody at 19 hours due to higher residual background activity in CD20 negative tumor. Conclusion Radioiodinated minibody and scFv-Fc fragment produced excellent, high-contrast images in vivo. These new immunoPET agents may prove useful for the imaging CD20 positive lymphomas in preclinical models and in humans with NHL. PMID:19690034

    There are limited data to guide the choice of high-dose therapy (HDT) regimen prior to autologous hematopoietic cell transplantation (AHCT) for patients with Hodgkin (HL) and non-Hodgkin lymphoma (NHL). We studied 4,917 patients (NHL n=3,905; HL n=1,012) who underwent AHCT from 1995-2008 using the most common HDT platforms: BEAM (n=1730), CBV (n=1853), BuCy (n=789), and TBI-containing (n=545). CBV was divided into CBVhigh and CBVlow based on BCNU dose. We analyzed the impact of regimen on development of idiopathic pulmonary syndrome (IPS), transplant-related mortality (TRM), progression free and overall survival (PFS and OS). The 1-year incidence of IPS was 3-6% and was highest in recipients of CBVhigh (HR 1.9) and TBI (HR 2.0) compared to BEAM. 1-year TRM was 4-8% and was similar between regimens. Among patients with NHL, there was a significant interaction between histology, HDT regimen, and outcome. Compared to BEAM, CBVlow (HR 0.63) was associated with lower mortality in follicular lymphoma (p<0.001), and CBVhigh (HR1.44) with higher mortality in diffuse large B-cell lymphoma (p=0.001). For patients with HL, CBVhigh (HR1.54), CBVlow (HR1.53), BuCy (HR1.77) and TBI (HR 3.39) were associated with higher mortality compared to BEAM (p<0.001). The impact of specific AHCT regimen on post transplant survival is different depending on histology; therefore, further studies are required to define the best regimen for specific diseases.

    Radiation therapy (RT) is the most effective single modality for local control of non-Hodgkin lymphoma (NHL) and is an important component of therapy for many patients. Many of the historic concepts of dose and volume have recently been challenged by the advent of modern imaging and RT planning tools. The International Lymphoma Radiation Oncology Group (ILROG) has developed these guidelines after multinational meetings and analysis of available evidence. The guidelines represent an agreed consensus view of the ILROG steering committee on the use of RT in NHL in the modern era. The roles of reduced volume and reduced doses are addressed, integrating modern imaging with 3-dimensional planning and advanced techniques of RT delivery. In the modern era, in which combined-modality treatment with systemic therapy is appropriate, the previously applied extended-field and involved-field RT techniques that targeted nodal regions have now been replaced by limiting the RT to smaller volumes based solely on detectable nodal involvement at presentation. A new concept, involved-site RT, defines the clinical target volume. For indolent NHL, often treated with RT alone, larger fields should be considered. Newer treatment techniques, including intensity modulated RT, breath holding, image guided RT, and 4-dimensional imaging, should be implemented, and their use is expected to decrease significantly the risk for normal tissue damage while still achieving the primary goal of local tumor control.

    Contamination of autologous blood cell transplants with cells of follicular non-Hodgkin's lymphoma (F-NHL) may contribute to relapse of the malignancy after potentially curative high doses of chemotherapy and radiotherapy. In an attempt to circumvent this limitation, we have evaluated various techniques of selection of CD34+ cells to eliminate malignant cells from blood cell transplants of five patients with F-NHL undergoing high-dose sequential therapy. The contamination of F-NHL cells was evaluated using a nested PCR assay for the detection of bcl-2-IgH rearrangement with a sensitivity of one F-NHL cell in 10(5) normal cells. In two experiments with blood cell transplant fractions of 0.5 x 10(9) nucleated cells, negative selection of CD34+ cells by removal of B cells and other mature cells that naturally adhere to nylon wool fibers decreased the number of CD19+ B cells detectable by flow cytometry but failed to eliminate bcl-2-IgH-positive F-NHL cells detectable by PCR. In contrast, positive selection of CD34+ cells by the Miltenyi MiniMACS high gradient magnetic cell sorting system in five separate experiments resulted in: (1) the elimination of F-NHL cells in four out of five cases as detected both flow cytometry and bclk-2-IgH PCR; (2) a highly purified population of hematopoietic progenitors comprising 90.8% +/- 2.3% CD34+ cells; and (3) the recovery of 77.9% +/- 3.2% CD34+ cells. These favorable results were confirmed on a large-scale with a blood cell transplant comprising 5.8 x 10(9) nucleated cells in which positive selection of CD34+ cells by the Miltenyi SuperMACS system resulted in: (1) the elimination of F-NHL cells as detected both by flow cytometry and bcl-2-IgH PCR; (2) a highly purified population of hematopoietic progenitors comprising 94.6% CD34+ cells; and (3) the recovery of 62.7% CD34+ cells. These results, attained with the newly available Super MACS system, compare favorable with previous techniques because they show the feasibility of

    Radioimmunotherapy (RIT) is an emerging treatment option for non-Hodgkin lymphoma (NHL) producing higher overall response and complete remission rates compared with unlabelled antibodies. However, the majority of patients treated with conventional or myeloablative doses of radiolabelled antibodies relapse. The development of RIT with alpha-emitters is attractive for a variety of cancers because of the high linear energy transfer (LET) and short path length of alpha-radiation in human tissue, allowing higher tumour cell kill and lower toxicity to healthy tissues. In this study, we investigated the molecular effects of the alpha-emitter Bi-213 labelled to anti-CD20 antibodies ([Bi-213]anti-CD20) on cell cycle and cell death in sensitive and radio-/chemoresistant NHL cells. [Bi-213]anti-CD20 induced apoptosis, activated caspase-3, caspase-2 and caspase-9 and cleaved PARP specifically in CD20-expressing sensitive as well as in chemoresistant, beta-radiation resistant and gamma-radiation resistant NHL cells. CD20 negative cells were not affected by [Bi-213]anti-CD20 and unspecific antibodies labelled with Bi-213 could not kill NHL cells. Breaking radio-/chemoresistance in NHL cells using [Bi-213]anti-CD20 depends on caspase activation as demonstrated by complete inhibition of [Bi-213]anti-CD20-induced apoptosis with zVAD.fmk, a specific inhibitor of caspases activation. This suggests that deficient activation of caspases was reversed in radioresistant NHL cells using [Bi-213]anti-CD20. Activation of mitochondria, resulting in caspase-9 activation was restored and downregulation of Bcl-xL and XIAP, death-inhibiting proteins, was found after [Bi-213]anti-CD20 treatment in radio-/chemosensitive and radio-/chemoresistant NHL cells. [Bi-213]anti-CD20 seems to be a promising radioimmunoconjugate to improve therapeutic success by breaking radio- and chemoresistance selectively in CD20-expressing NHL cells via re-activating apoptotic pathways through reversing deficient

    Background This study describes epidemiological data of non-Hodgkin’s lymphoma (NHL) diagnosed from 2001 to 2008 among Saudi men. Materials and methods Retrospective data from all NHL cancer cases among Saudi men recorded in the Saudi Cancer Registry (SCR) between January 2001 and December 2008 were used. Descriptive statistics, analysis of variance, Poisson regression, and simple linear regression were also used. Results In total, 2,555 new cases of NHL were recorded between January 2001 and December 2008. The region of Riyadh, Saudi Arabia had the highest overall age-standardized incidence rate (ASIR) at 7.8, followed by the Eastern region at 6.8, and Makkah at 6.1 per 100,000 men; however, Jazan, Hail, and Baha had the lowest average ASIRs at 2.5, 3.7, and 3.9 per 100,000 men, respectively. The incidence-rate ratio for the number of NHL cases was significantly higher in Riyadh (4.68, 95% confidence interval [CI] 4.11–5.32), followed by Makkah (4.47, 95% CI 3.94–5.07), and the Eastern region of Saudi Arabia (3.27, 95% CI 2.90–3.69) than that in the reference region of Jazan. Jouf had the highest changes in the ASIRs of NHL among Saudi men from 2001 and 2008 (5.0 per 100,000 men). Conclusion A significant increase in the crude incidence rate and ASIR for NHL in Saudi Arabia between 2001 and 2008 was found. Riyadh, the Eastern region, and Makkah had the highest overall ASIR in Saudi Arabia. Jazan, Hail, and Baha had the lowest rates. Additionally, Riyadh, Makkah, and the Eastern region had the highest incidence-rate ratio for the number of NHL cases. Finally, Jouf had the highest changes in crude incidence rate and ASIR from 2001 to 2008. Further analytical studies are needed to determine the potential risk factors of NHL among Saudi men.

    Enolases are glycolytic enzymes responsible for the ATP-generated conversion of 2-phosphoglycerate to phosphoenolpyruvate. In addition to the glycolytic function, Enolase 1 (ENO1) has been reported up-regulation in several tumor tissues. In this study, we investigated the expression and biologic function of ENO1 in Non-Hodgkin's Lymphomas (NHLs). Clinically, by western blot analysis we observed that ENO1 expression was apparently higher in diffuse large B-cell lymphoma than in the reactive lymphoid tissues. Subsequently, immunohistochemical staining of 144 NHLs suggested that the expression of ENO1 was significantly lower in the indolent lymphomas compared with the progressive lymphomas. Further, we identified ENO1 as an independent prognostic factor, and it was significantly correlated with overall survival of NHL patients. In addition, we found that ENO1 could promote cell proliferation, regulate cell cycle associated gene and PI3K/AKT signaling pathway in NHLs. Finally, we verified that ENO1 participated in the process of lymphoma cell adhesion mediated drug resistance (CAM-DR). Adhesion to FN or HS5 cells significantly protected OCI-Ly8 and Daudi cells from cytotoxicity compared with those cultured in suspension, and these effects were attenuated when transfected with ENO1-siRNA. Based on the study, we propose that inhibition of ENO1 expression may be a novel strategy for therapy for NHLs patients, and it may be a target for drug resistance. - Highlights: • ENO1 expression is reversely correlated with clinical outcomes of patients with NHLs. • ENO1 promotes the proliferation of NHL cells. • ENO1 regulates cell adhesion mediated drug resistance.

    Toxic epidermal necrolysis (TEN) is a disease which is characterized by fever and desquamation of the skin and mucosal membranes. It is usually related with drugs, especially aromatic anticonvulsants which are recognized as the most common cause of this disorder. Cranial irradiation may act as a precipitating factor along with anticonvulsants for the development of TEN. We report a 28-year-old patient with central nervous system (CNS) relapsed non-Hodgkin lymphoma (NHL) who developed TEN after cranial radiotherapy and concurrent phenytoin treatment. PMID:26900363

    The outcome of children, adolescents and young adults (CAYA) with poor-risk recurrent/refractory lymphoma is dismal (⩽30%). To overcome this poor prognosis, we designed an approach to maximize an allogeneic graft vs lymphoma effect in the setting of low disease burden. We conducted a multi-center prospective study of myeloablative conditioning (MAC) and autologous stem cell transplantation (AutoSCT), followed by a reduced intensity conditioning (RIC) and allogeneic hematopoietic cell transplantation (AlloHCT) in CAYA, with poor-risk refractory or recurrent lymphoma. Conditioning for MAC AutoSCT consisted of carmustine/etoposide/cyclophosphamide, RIC consisted of busulfan/fludarabine. Thirty patients, 16 Hodgkin lymphoma (HL) and 14 non-Hodgkin lymphoma (NHL), with a median age of 16 years and median follow-up of 5years, were enrolled. Twenty-three patients completed both MAC AutoSCT and RIC AlloHCT. Allogeneic donor sources included unrelated cord blood (n=9), unrelated donor (n=8) and matched siblings (n=6). The incidence of transplant-related mortality following RIC AlloHCT was only 12%. In patients with HL and NHL, 10 year EFS was 59.8% and 70% (P=0.613), respectively. In summary, this approach is safe, and long-term EFS with this approach is encouraging considering the poor-risk patient characteristics and the use of unrelated donors for RIC AlloHCT in the majority of cases.

    Most non-Hodgkin lymphomas (NHLs) are of B-cell origin, but the tumor tissue can be variably infiltrated with T cells. In the present study, we have identified a subset of CD4+CD25+ T cells with high levels of CTLA-4 and Foxp3 (intratumoral Treg cells) that are overrepresented in biopsy specimens of B-cell NHL (median of 17% in lymphoma biopsies, 12% in inflammatory tonsil, and 6% in tumor-free lymph nodes; P = .001). We found that these CD4+CD25+ T cells suppressed the proliferation and cytokine (IFN-γ and IL-4) production of infiltrating CD4+CD25- T cells in response to PHA stimulation. PD-1 was found to be constitutively and exclusively expressed on a subset of infiltrating CD4+CD25- T cells, and B7-H1 could be induced on intratumoral CD4+CD25+ T cells in B-cell NHL. Anti-B7-H1 antibody or PD-1 fusion protein partly restored the proliferation of infiltrating CD4+CD25- T cells when cocultured with intratumoral Treg cells. Finally, we found that CCL22 secreted by lymphoma B cells is involved in the chemotaxis and migration of intratumoral Treg cells that express CCR4, but not CCR8. Taken together, our results suggest that Treg cells are highly represented in the area of B-cell NHL and that malignant B cells are involved in the recruitment of these cells into the area of lymphoma.

    Under the generic diagnosis of angiocentric and intravascular lymphomas are included several subtypes of lymphomas histopathologically characterized either by the predominantly endovascular-endoluminal presence of neoplastic lymphocytes of B-T or NK/T cell origin, or by a pathologic process centered around a blood vessels secondarily infiltrated and invaded by the spreading infiltrate. This group of lymphoproliferative disorders is heterogeneous regarding phenotype, but they share common features that are multiorgan involvement, worse prognosis, and, frequently Ebstein-Barr virus (EBV) genomic integration. At onset, some of these rare lymphomas, e.g. intravascular large cell lymphoma or lymphomatoid granulomatosis (Liebow dieases), are misdiagnosed as inflammatory diseases. The actual treatments of these disorders are based upon chemotherapy and/or chemotherapy plus bone marrow transplantation with variable results. Therapeutic approaches for EBV related angiocentric and intravascular lymphomas, similarly to those employed for other viral induced lymphoproliferative disease would comprise the employment of chemotherapy together with drugs able to interfere with viral infection. Such an approach has been used in rare cases of EBV-positive diffuse large B-cell lymphoma of the elderly, a lymphoproliferative disorders which development is linked to immunosuppression due to senescence. The present review will focus on intravascular and angiocentric lymphomas providing histopathologic, immunophenotypical and molecular data useful to overcome to a specific diagnosis and to differentiate them from other lymphoproliferative disorders showing a secondary vascular engulfment and infiltration and some vasculitides showing overlapping histopathologic features.

    Primary central nervous system lymphoma (PCNSL) has long been associated with an inferior prognosis compared to other aggressive non-Hodgkin’s lymphomas (NHLs). However, during the past 10 years an accumulation of clinical experience has demonstrated that long-term progression-free survival (PFS) can be attained in a major proportion of PCNSL patients who receive dose-intensive consolidation chemotherapy and avoid whole brain radiotherapy. One recent approach that has reproducibly demonstrated efficacy for newly diagnosed PCNSL patients is an immunochemotherapy combination regimen used during induction that consists of methotrexate, temozolomide, and rituximab followed by consolidative infusional etoposide plus high-dose cytarabine (EA), administered in first complete remission (CR). Other high-dose chemotherapy-based consolidative regimens have shown efficacy as well. Our goal in this review is to update principles of diagnosis and management as well as data regarding the molecular pathogenesis of PCNSL, information that may constitute a basis for development of more effective therapies required to make additional advances in this phenotype of aggressive NHL.

    Plasmablastic lymphoma (PBL) is an aggressive subtype of non-Hodgkin's lymphoma (NHL), which frequently arises in the oral cavity of human immunodeficiency virus (HIV) infected patients. PBL shows diffuse proliferation of large neoplastic cells resembling B-immunoblasts/plasmablasts, or with plasmacytic features and an immunophenotype of plasma cells. PBL remains a diagnostic challenge due to its peculiar morphology and an immunohistochemical profile similar to plasma cell myeloma (PCM). PBL is also a therapeutic challenge with a clinical course characterized by a high rate of relapse and death. There is no standard chemotherapy protocol for treatment of PBL. Cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP-like regimens have been the backbone while more intensive regimens such as cyclophosphamide, vincristine, doxorubicin, high-dose methotrexate/ifosfamide, etoposide, high-dose cytarabine (CODOX-M/IVAC), or dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (DA-EPOCH) are possible options. Recently, a few studies have reported the potential value of the proteasome inhibitor bortezomib and thalidomide in PBL patients. The introduction of genes encoding artificial receptors called chimeric antigen receptors (CARs) and CAR-modified T cells targeted to the B cell-specific CD19 antigen have demonstrated promising results in multiple early clinical trials. The aim of this paper is to review the recent advances in epidemiology; pathophysiology; clinical, pathologic, and molecular characteristics; therapy; and outcome in patients with PBL. PMID:26357515

    Bendamustine (Treanda, Ribomustin) was recently approved by the US Food and Drug Administration (FDA) for treatment of patients with rituximab refractory indolent lymphoma and is expected to turn into a frontline therapy option for indolent lymphoma. This compound with amphoteric properties was designed in the former Germany Democratic Republic in 1960s and re-discovered in 1990s with multiple successive well-designed studies. Bendamustine possesses a unique mechanism of action with potential antimetabolite properties, and only partial cross-resistance with other alkylators. Used in combination with rituximab in vitro, bendamustine shows synergistic effects against various leukemia and lymphoma cell lines. In clinical studies, bendamustine plus rituximab is highly effective in patients with relapsed-refractory indolent lymphoma, inducing remissions in 90% or more and a median progression-free survival of 23–24 months. The optimal dosing and schedule of bendamustine administration is largely undecided and varies among studies. Results of ongoing trials and dose-finding studies will help to further help ascertain the optimal place of bendamustine in the management of indolent NHL. PMID:21695099

    There is warranted interest in assessing the association between residential radon exposure and the risk of childhood cancer. We sought to evaluate the association between residential radon exposure and the incidence of childhood lymphoma in Texas. The Texas Cancer Registry (n = 2147) provided case information for the period 1995–2011. Denominator data were obtained from the United States Census. Regional arithmetic mean radon concentrations were obtained from the Texas Indoor Radon Survey and linked to residence at diagnosis. Exposure was assessed categorically: ≤25th percentile (reference), >25th to ≤50th percentile, >50th to ≤75th percentile, and >75th percentile. Negative binomial regression generated adjusted incidence rate ratios (aIRR) and 95% confidence intervals (CI). We evaluated lymphoma overall and by subtype: Hodgkin (HL; n = 1248), Non-Hodgkin excluding Burkitt (non-BL NHL; n = 658), Burkitt (BL; n = 241), and Diffuse Large B-cell (DLBCL; n = 315). There was no evidence that residential radon exposure was positively associated with lymphoma overall, HL, or BL. Areas with radon concentrations >75th percentile had a marginal increase in DLBCL incidence (aIRR = 1.73, 95% CI: 1.03–2.91). In one of the largest studies of residential radon exposure and the incidence of childhood lymphoma, we found little evidence to suggest a positive or negative association; an observation consistent with previous studies.

    Highlights: • CD9 is differentially expressed in human Burkitt’s lymphoma cells. • We found that CD9 expression promotes these cells proliferation. • CD9 expression also increases HDAC activity. • HDAC inhibition decreased both cell proliferation and importantly CD9 expression. • CD9 may dictate HDAC efficacy and play a role in HDAC regulation. - Abstract: Non-Hodgkin Lymphoma (NHL) is a type of hematological malignancy that affects two percent of the overall population in the United States. Tetraspanin CD9 is a cell surface protein that has been thoroughly demonstrated to be a molecular facilitator of cellular phenotype. CD9 expression varies in two human lymphoma cell lines, Raji and BJAB. In this report, we investigated the functional relationship between CD9 and cell proliferation regulated by histone deacetylase (HDAC) activity in these two cell lines. Introduction of CD9 expression in Raji cells resulted in significantly increased cell proliferation and HDAC activity compared to Mock transfected Raji cells. The increase in CD9–Raji cell proliferation was significantly inhibited by HDAC inhibitor (HDACi) treatment. Pretreatment of BJAB cells with HDAC inhibitors resulted in a significant decrease in endogenous CD9 mRNA and cell surface expression. BJAB cells also displayed decreased cell proliferation after HDACi treatment. These results suggest a significant relationship between CD9 expression and cell proliferation in human lymphoma cells that may be modulated by HDAC activity.

    Primary ovarian lymphoma is a rare entity. We submit a case of a 34-year-old black patient presenting with a bilateral adnexal tumor. She underwent hysterectomy with double salpingo-oophorectomy followed by polychemotherapy treatment. Histology confirmed Epstein-Barr virus-positive bilateral Burkitt's lymphoma. The patient died from septic shock after a month of treatment. Endemic Burkitt's lymphoma has a predilection for the female genital tract, manifesting itself clinically as a pelvic mass and less frequently as a menstrual disorder. It is a rare entity in our environment but should be kept in mind when treating patients of African origin. PMID:19480266

    Nine cases of oral extranodal lymphomas are described. Histologically, 6 cases were histiocytic, 2 lymphocytic and 1 Burkitt's lymphoma. According to the criteria of the Japanese Lymphoma Study Group, 8 cases seemingly belonged to the B-cell lymphoma classification, and one was unclassified. Geographical differences in the distribution of oral extranodal lymphomas between Japan and western countries were surveyed. A review of our cases and those in the literature revealed no significant difference in sex, age, frequency of B-cell lymphomas or site of predilection. In Japan, histiocytic lymphomas were the most common type of extranodal oral lymphomas. The most prevalent type of oral extranodal lymphomas in western countries could not be determined from the literature. PMID:6808100

    Recovery rates for B-cell Non-Hodgkin’s Lymphoma (NHL) are up to 70% with current standard-of-care treatments including rituximab (chimeric anti-CD20 monoclonal antibody) in combination with chemotherapy (R-CHOP). However, patients who do not respond to first-line treatment or develop resistance have a very poor prognosis. This signifies the need for the development of an optimal treatment approach for relapsed/refractory B-NHL. Novel CD19- chimeric antigen receptor (CAR) T-cell redirected immunotherapy is an attractive option for this subset of patients. Anti-CD19 CAR T-cell therapy has already had remarkable efficacy in various leukemias as well as encouraging outcomes in phase I clinical trials of relapsed/refractory NHL. In going forward with additional clinical trials, complementary treatments that may circumvent potential resistance mechanisms should be used alongside anti-CD19 T-cells in order to prevent relapse with resistant strains of disease. Some such supplementary tactics include conditioning with lymphodepletion agents, sensitizing with kinase inhibitors and Bcl-2 inhibitors, enhancing function with multispecific CAR T-cells and CD40 ligand-expressing CAR T-cells, and safeguarding with lymphoma stem cell-targeted treatments. A therapy regimen involving anti-CD19 CAR T-cells and one or more auxiliary treatments could dramatically improve prognoses for patients with relapsed/refractory B-cell NHL. This approach has the potential to revolutionize B-NHL salvage therapy in much the same way rituximab did for first-line treatments. PMID:27186412

    The purpose of this work was to modernize recommendations for evaluation, staging, and response assessment of patients with Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL). A workshop was held at the 11th International Conference on Malignant Lymphoma in Lugano, Switzerland, in June 2011, that included leading hematologists, oncologists, radiation oncologists, pathologists, radiologists, and nuclear medicine physicians, representing major international lymphoma clinical trials groups and cancer centers. Clinical and imaging subcommittees presented their conclusions at a subsequent workshop at the 12th International Conference on Malignant Lymphoma, leading to revised criteria for staging and of the International Working Group Guidelines of 2007 for response. As a result, fluorodeoxyglucose (FDG) positron emission tomography (PET)–computed tomography (CT) was formally incorporated into standard staging for FDG-avid lymphomas. A modification of the Ann Arbor descriptive terminology will be used for anatomic distribution of disease extent, but the suffixes A or B for symptoms will only be included for HL. A bone marrow biopsy is no longer indicated for the routine staging of HL and most diffuse large B-cell lymphomas. However, regardless of stage, general practice is to treat patients based on limited (stages I and II, nonbulky) or advanced (stage III or IV) disease, with stage II bulky disease considered as limited or advanced disease based on histology and a number of prognostic factors. PET-CT will be used to assess response in FDG-avid histologies using the 5-point scale. The product of the perpendicular diameters of a single node can be used to identify progressive disease. Routine surveillance scans are discouraged. These recommendations should improve evaluation of patients with lymphoma and enhance the ability to compare outcomes of clinical trials. PMID:25113753

    Treatment regimens involving obinutuzumab (GA101) demonstrated increased efficacy to rituximab in clinical trials for non-Hodgkin's lymphoma (NHL) and chronic lymphocytic leukemia (CLL). However, the pharmacokinetic (PK) properties and the exposure-response relationships of obinutuzumab still need to be fully described. Data from four clinical trials of obinutuzumab were analyzed to describe the PK properties in patients with NHL or CLL and the pharmacodynamic (PD) properties in patients with CLL. A population PK model with linear time-dependent clearance described the obinutuzumab concentration-time course. Diagnosis, baseline tumor size (BSIZ), body weight, and gender were the main covariates affecting obinutuzumab exposure. In patients with CLL, exposure was not associated with safety but showed positive trends of correlation with efficacy. Although efficacy correlated positively with exposure, since both efficacy and exposure correlated negatively with BSIZ, it was not possible to determine with certainty whether it would be beneficial to adjust the dose according to BSIZ.

    We analyzed the outcomes of 248 (61% male) adult recipients of HLA-matched unrelated and HLA-mismatched related donor hematopoietic cell transplantation (HCT) for non-Hodgkin lymphoma (NHL) after reduced or lower intensity conditioning (RIC), reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) from 1997 to 2004. Median age was 52 (range, 18–72 yrs); 31% had a Karnofsky performance score <90. Follicular NHL (43%) was the major histology. Incidence of grades II–IV acute graft-versus-host disease (GVHD) was 43% at 100 days; and chronic GVHD was 44% at three years. Treatment-related mortality (TRM) at 100 days was 24%. Three-year overall survival (OS) and progression-free survival (PFS) were 41% and 32%, respectively. In multivariate analysis, use of anti-thymocyte globulin (ATG) and HLA mismatch were associated with increased TRM. High-grade histology, ATG use and chemotherapy resistance were associated with lower progression-free survival (PFS). Older age, shorter interval from diagnosis to HCT, non-TBI conditioning regimens, ex vivo T-cell depletion and HLA-mismatched unrelated donors were associated with mortality. GVHD did not influence relapse or PFS. Older age, aggressive histology and chemotherapy resistance correlated with poorer survival. For selected patients with NHL, lack of an available sibling donor should not be a barrier to allogeneic HCT. PMID:22155506

    In order to improve the prognosis of patients with localized non-Hodgkin's lymphomas (NHL) who are treated with radiotherapy (RT), a prospective controlled study utilizing a combined modality approach was carried out in patients with pathologic Stage I-II NHL. After treatment with regional RT, patients in complete remission were randomized to receive either no further therapy or 6 cycles of cyclophosphamide, vincristine and prednisolone (CVP). At 5 years from completion of irradiation, the relapse-free survival was 46.3% after RT and 72.1% after RT plus CVP (P=0.005). The corresponding findings for the overall survival calculated from the beginning of irradiation were 55.8 and 82.8% respectively (P=0.03). The favorable effects of adjuvant chemotherapy on relapse-free survival were statistically significant only in the subgroup with diffuse histology. In patients who relapsed after RT alone, the salvage therapy failed to induce a high incidence of second durable remission. Adjuvant chemotherapy is indicated to improve the curve rate in pathologic stage I-II NHL with diffuse histology when regional RT is utilized.

    To investigate the range of pathology shown by acquired immune deficiency syndrome (AIDS)-related lymphomas arising in an epidemiologically well-defined group of patients, all cases of lymphoma recognized in Danish human immunodeficiency virus (HIV)-infected individuals up to the end of 1988 were studied. Twenty-seven cases (26 high-grade non-Hodgkin's lymphoma [NHL], 1 Hodgkin's disease) were found, to give a cumulative incidence rate of 8% among Danish AIDS patients. Morphologically most NHL patients were classified into two groups: 1) high-grade tumors with a predominant population of immunoblasts, either monomorphic or more often polymorphic with plasmacytic differentiation; 2) Burkitt-type. Of 26 NHLs, 22 had a B-cell paraffin-section immunophenotype and 4 were non-B, non-T. Epstein-Barr virus (EBV) DNA was demonstrated in tumor cells of 12 of 24 cases (50%) using in situ nucleic acid hybridization with a 35S-labeled probe in paraffin sections. Epstein-Barr virus DNA was found in 65% of group 1 and 20% of group 2 tumors. This study suggests the existence of two main groups of AIDS-related lymphoma with different pathogeneses. First there are immunoblast-rich lesions, which usually are associated with EBV and morphologically resemble lymphomas described in immunosuppressed organ-transplantation patients. Second there are Burkitt-type tumors in which EBV sequences are less common and that may be pathogenetically analogous to sporadic Burkitt's lymphoma.

    Lymphomas are malignant neoplasms of the lymphoid lineage. They are broadly classified as either Hodgkin disease or as non-Hodgkin lymphoma (NHL). Burkitt's lymphoma, a variety of NHL, is significantly most common in sub-Saharan Africa, where it accounts for approximately one half of childhood cancers. Lymphoblastic lymphoma is less common. A case of paravertebral high grade non-Hodgkin's lymphoma (lymphoblastic lymphoma) “masquerading” as Pott's disease in a 13-year-old child is reported. The present report was informed by the unusual presentation of this case and the intent of increasing the index of diagnostic suspicion. A brief appraisal is provided of the clinical parameters, management strategies and challenges. AT was a 13-year boy that presented on account of a slowly evolving and progressively increasing hunch on the back and inability to walk over 4 and 8 months duration, respectively. There was subsequent inability to control defecation and urination. There was no history of cough. He and his twin brother lived with their paternal grandfather who had chronic cough with associated weight loss. The grandfather died shortly before the child's admission. The child had no BCG immunization. The essential findings on examination were in keeping with lower motor neurons (LMN) paralysis of the lower limbs. The upper limbs appeared normal. There was loss of cutaneous sensation from the umbilicus (T10) downward. There was a firm, (rather tense), non-tender non-pulsatile, smooth swelling over the mid-third of the back (T6-L1) the mass had no differential warmth. It measures about 20×12 cm.

    Introduction Extranodal non-Hodgkin lymphomas (NHLs) are commonly described in patients with acquired immunodeficiency syndrome (AIDS) and are related with an atypical morphology and aggressive clinical course. AIDS-associated lymphomas are characterized by their rapid progression, frequent extranodal manifestations, and poor outcome. Objective The aim of this article is to remake the clinical features of head and neck (HN) NHL in patients with AIDS to facilitate early diagnosis and treatment. Methods We evaluated the epidemiologic, clinical, immunologic, virologic, and histopathologic characteristics of 24 patients with human immunodeficiency virus (HIV)/AIDS with primary HN NHL treated at a single institution between 2002 and 2012. Histopathologic diagnosis was made according to the criteria of the World Health Organization Classification of Tumors of Hematopoietic and Lymphoid Tissues. Additional immunohistochemical stains were applied in all cases. Results Eighteen patients (75%) were men and the median of age was 39 years. The gingiva and the hard palate were the most common sites of the lesions (15 patients, 62.5%). Lactate dehydrogenase levels were elevated in 16 cases (84%). Bone marrow infiltration was detected only in 4 cases (16.6%). The median CD4 T-cell count was 100 cells/µL. According to the histopathologic evaluation, the most common subtype was diffuse large B-cell lymphoma (12 cases, 50%), followed by plasmablastic lymphoma (9 cases, 37.5%) and Burkitt lymphoma (3 cases, 12.5%). Conclusion HN NHL is a severe complication of advanced HIV/AIDS disease. Early diagnosis followed by chemotherapy plus highly active antiretroviral treatment is necessary to improve the prognosis and the survival of these patients. PMID:25992103

Clinical, paraclinical, and radiological data was collected from medical records of the patients. Results: Out of the 30 patients with primary GI lymphoma in the study, 12 were female (40%) and 18 were male (60%) (male to female ratio: 3/2). B symptoms were present in 27 patients (90%). Antidiuretic hormone (LDH) levels were elevated in 9 patients (32.1%). The most common primary site was stomach in 14 cases (46.7%). Other common sites included small intestine and colon each in 8 patients (26.7%). All patients had histopathologically proven non-Hodgkin's lymphoma. The most common histologic subtype was diffuse large B-cell lymphoma (DLBL) in 16 patients (53.3%). In addition, 28 patients (93.3%) received chemotherapy with cyclophosphamide, vincristine, doxorubicin, prednisolone (CHOP regimen). The median course of chemotherapy was 6 cources. Moreover, 8 patients (26.7%) received radiotherapy with cobalt 60. The median follow-up time was 26 months. The overall 5-year survival rate was 53% and the median survival time was 60 months. Conclusion: Primary GI lymphoma is commonly seen in stomach and small intestine and mostly is DLBCL or mucosa-associated lymphoid tissue (MALT) lymphoma. PMID:23626617

    Busulfan, cyclophosphamide, and etoposide (BuCyE) is a commonly used conditioning regimen for autologous stem cell transplantation (ASCT). This multicenter, phase II study examined the safety and efficacy of BuCyE with individually adjusted busulfan based on preconditioning pharmacokinetics. The study initially enrolled Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) patients ages 18 to 80 years but was amended due to high early treatment-related mortality (TRM) in patients > 65 years. BuCyE outcomes were compared with contemporaneous recipients of carmustine, etoposide, cytarabine, and melphalan (BEAM) from the Center for International Blood and Marrow Transplant Research. Two hundred seven subjects with HL (n = 66) or NHL (n = 141) were enrolled from 32 centers in North America, and 203 underwent ASCT. Day 100 TRM for all subjects (n = 203), patients > 65 years (n = 17), and patients ≤ 65 years (n = 186) were 4.5%, 23.5%, and 2.7%, respectively. The estimated rates of 2-year progression-free survival (PFS) were 33% for HL and 58%, 77%, and 43% for diffuse large B cell lymphoma (DLBCL; n = 63), mantle cell lymphoma (MCL; n = 29), and follicular lymphoma (FL; n = 23), respectively. The estimated rates of 2-year overall survival (OS) were 76% for HL and 65%, 89%, and 89% for DLBCL, MCL, and FL, respectively. In the matched analysis rates of 2-year TRM were 3.3% for BuCyE and 3.9% for BEAM, and there were no differences in outcomes for NHL. Patients with HL had lower rates of 2-year PFS with BuCyE, 33% (95% CI, 21% to 46%), than with BEAM, 59% (95% CI, 52% to 66%), with no differences in TRM or OS. BuCyE provided adequate disease control and safety in B cell NHL patients ≤ 65 years but produced worse PFS in HL patients when compared with BEAM. PMID:27040394

    The usefulness of multiparameter flow cytometric (FC) analysis of cerebrospinal fluid (CSF) was evaluated in leukemia/lymphoma patients having central nervous system (CNS) involvement of the disease. In 12 specimens of 8 patients with different types of leukemia/lymphoma (one case of T-ALL, 3 cases of early B-cell ALL, one case of AML, and 3 proven or suspicious NHL cases) the presence of pathological clone in CSF has been confirmed or excluded. The phenotypic patterns of CSF cells were defined according to those of bone marrow (BM)/peripheral blood (PB) at diagnosis or during follow-up of the same patients. Furthermore, in one case of suspicious CNS infiltration of NHL, the pathological clone was characterized as a highly suspicious of solid tumor and was proved to be a lung cancer metastasis. The definition was made on the basis of CD45 (common leukocyte antigen) and other studied CD markers negativity. The exact comparison of immunophenotypic profiles of specimens from different sites (CSF, BM, PB) of the same patient has been performed and no phenotypic changes were found. In some CSF specimens, where no cells of suspicious pathological clone were detected, in 4-color analysis only normal lymphocyte population was found even in small cell samples (even if the cellularity was < than 0.3x10-6). In these populations the high values of T-cells (CD3+) predominated and the high prevalence of CD4+ over CD8+ cells, and an almost total lack of B-lymphocytes was found. Our results suggest that positive CSF immunology is a useful indicator of malignancy and reflects leptomeningeal involvement. Simultaneously we demonstrated that FC analysis of CSF in the aim to detect possible CSF seeding of leukemia/lymphoma is a reliable and quick technique. PMID:15640938

    Nasal-paranasal oropharyngeal (NPOP) non-Hodgkin's lymphoma (NHL) is a disease of the very young (median age, 5 years) and of the aging adult (median age, 50-60 years). Of a total of 208 pediatric patients with NHL studied, 20 (9.6%) had primary NPOP. Sixty percent of the patients had Stage I and II disease. Primary sites were maxillary sinus in eight patients; tonsils in eight; posterior pharynx in two; mandible in one; and orbit in one patient. Histologically, the disease is different than that of the adults since most patients had B-cell lymphomas of the diffuse undifferentiated type (Rappaport) or small cell non-cleaved types (Lukes-Collins, Kiel, and Working Formulation). None of these patients had gastrointestinal involvement. All patients were treated with the LSA2-L2 regimen and radiation therapy was given to primary unresectable tumors and regional metastases. The lymphoma event-free survival was 75%, with a median observation period of 99+ months. In staging systems that refer mostly to amount of disease outside of the primary (such as ours, Murphy's, and the Ann Arbor staging systems) stage did not correlate well with disease-free survival. In the TNM staging of 1977, a staging system that refers to size of primary tumor as well as regional and systemic disease, stage correlated better with prognosis and survival. In our staging system, eight of 12 patients (66.7%) with Stage I and II disease; four of four with Stage III; two of two with Stage IVA; and zero of two with Stage IVB survived. In the TNM staging system, three of three patients with Stage II and III disease and 12 of 18 patients (67%) with Stage IV disease survived. All recurrences occurred early suggesting that early intensification of chemotherapy may produce better results. PMID:2306688

    Background: Primary lymphoma of bone is a rare disease. There is yet no systematical evaluation of primary lymphoma of bone in Korea. Here we report our experience of sixteen cases with primary lymphoma of bone focusing on the survival. Methods: Sixteen cases, collected for 13 years, were evaluated on the clinical presentation, histologic subtype, stage and treatment outcomes of the primary bone lymphoma. Results: The most common presenting complaint was bone pain. Malignant lymphoma of bone involved a wide variety of sites, the most prevalent site of which in this study was the spine. Most of the cases were in the diffuse large B-cell category. The clinical stage of lymphoma was IEA in two cases, IIEA in three cases, IVEA in five cases and IVEB in three cases. All treated cases received systemic chemotherapy and ten cases among them were treated with combined modality therapy. Median overall survival was not reached after median follow-up period of 28 months and five-year overall survival rate was 54%. Conclusion: More promising therapeutic strategies are needed for survival improvement on more accumulated cases. PMID:12298430

    The incidence of lymphoma in patients with HIV infection greatly exceeds that of the general population. The increased risk for lymphoma appears related to multiple factors, including the transforming properties of the retrovirus itself, the immunosuppression and cytokine dysregulation that results from the disease, and, most importantly, opportunistic infections with other lymphotrophic herpes viruses such as Epstein–Barr virus and human herpesvirus 8. Histologically lymphomas fall into three groups: (1) those also occurring in immunocompetent patients; (2) those occurring more specifically in HIV‐positive patients; and (3) those also occurring in patients with other forms of immunosuppression. Aggressive lymphomas account for the vast majority cases. They frequently present with advanced stage, bulky disease with high tumour burden and, typically, involve extranodal sites. Clinical outcome appears to be worse than in similar aggressive lymphomas in the general population. However, following the introduction of highly active antiretroviral therapy, the risk for developing lymphoma in the context of HIV infection has decreased and the clinical outcome has improved.

    Autophagy is a lysosomal degradation process that may act as a mechanism of survival in a variety of cancers. While pharmacologic inhibition of autophagy with hydroxychloroquine (HCQ) is currently being explored in human clinical trials, it has never been evaluated in canine cancers. Non-Hodgkin lymphoma (NHL) is one of the most prevalent tumor types in dogs and has similar pathogenesis and response to treatment as human NHL. Clinical trials in canine patients are conducted in the same way as in human patients, thus, to determine a maximum dose of HCQ that can be combined with a standard chemotherapy, a Phase I, single arm, dose escalation trial was conducted in dogs with spontaneous NHL presenting as patients to an academic, tertiary-care veterinary teaching hospital. HCQ was administered daily by mouth throughout the trial, beginning 72 h prior to doxorubicin (DOX), which was given intravenously on a 21-d cycle. Peripheral blood mononuclear cells and biopsies were collected before and 3 d after HCQ treatment and assessed for autophagy inhibition and HCQ concentration. A total of 30 patients were enrolled in the trial. HCQ alone was well tolerated with only mild lethargy and gastrointestinal-related adverse events. The overall response rate (ORR) for dogs with lymphoma was 93.3%, with median progression-free interval (PFI) of 5 mo. Pharmacokinetic analysis revealed a 100-fold increase in HCQ in tumors compared with plasma. There was a trend that supported therapy-induced increase in LC3-II (the cleaved and lipidated form of microtubule-associated protein 1 light chain 3/LC3, which serves as a maker for autophagosomes) and SQSTM1/p62 (sequestosome 1) after treatment. The superior ORR and comparable PFI to single-agent DOX provide strong support for further evaluation via randomized, placebo-controlled trials in canine and human NHL. PMID:24991836

    The purpose was study the feasibility of ESHAP + G-CSF for peripheral blood hematopoietic progenitor cell (PBPC) mobilisation in resistant/relapsed Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL). Twenty-two consecutive patients with HD (8) and N-HL (14) received ESHAP chemotherapy and G-CSF (5 microg/Kg/d). When a minimum number of 10,000 peripheral blood CD34+ cells/mL was observed patients underwent leukapheresis until a CD34+ cell dose > or = 2.5x10(6)/Kg was collected or the PBPC peak was lost. Blood cells kinetics and toxicity were analysed. Data concerning the day of first apheresis, number of procedures per patient, and cellular yield of the aphereses were recorded. Correlation between the CD34+ cell content in the apheresis product and the two diagnosis groups was attempted. Twelve patients (54%) developed short-lived severe neutropenia (<0.5x10(9)/L). Thrombocytopenia (<25x10(9)/L) had a median duration of 1 day. Fever appeared in 4 patients and CN Staph bacteriemia in 2 cases. Bleeding events did not supervene and no deaths occurred. Aphereses started at day +15 (median) and the median number of apheresis/patient was 2. Seventeen patients underwent 1 or 2 leukaphereses. Thirteen patients (59%) achieved the CD34+ cell target in the first apheresis. NHL patients obtained statistically significant better CD34+ cell collections than HD. Only 2 HD patients failed to mobilise, 1 previously treated with high-dose therapy and autologous bone marrow transplantation. ESHAP + G-CSF has been shown to be feasible for PBPC mobilisation in resistant/relapsed lymphoma. Toxicity was low and CD34+ cell yield high, especially in N-HL. This mobilisation regimen should be further explored in a larger patient population. PMID:10350339

    Primary mediastinal B-Cell lymphoma (PMBL) is a recently defined entity comprising ~2–10% non-Hodgkin lymphomas (NHL). Unlike most NHL subtypes, PMBL lacks recurrent gene rearrangements to serve as biomarkers or betray target genes. While druggable, late chemotherapeutic complications warrant the search for new targets and models. Well characterized tumor cell lines provide unlimited material to serve as preclinical resources for verifiable analyses directed at the discovery of new biomarkers and pathological targets using high throughput microarray technologies. The same cells may then be used to seek intelligent therapies directed at clinically validated targets. Four cell lines have emerged as potential PMBL models: FARAGE, KARPAS-1106P, MEDB-1 and U-2940. Transcriptionally, PMBL cell lines cluster near c(lassical)-HL and B-NHL examples showing they are related but separate entities. Here we document genomic alterations therein, by cytogenetics and high density oligonucleotide/SNP microarrays and parse their impact by integrated global expression profiling. PMBL cell lines were distinguished by moderate chromosome rearrangement levels undercutting cHL, while lacking oncogene translocations seen in B-NHL. In total 61 deletions were shared by two or more cell lines, together with 12 amplifications (≥4x) and 72 homozygous regions. Integrated genomic and transcriptional profiling showed deletions to be the most important class of chromosome rearrangement. Lesions were mapped to several loci associated with PMBL, e.g. 2p15 (REL/COMMD1), 9p24 (JAK2, CD274), 16p13 (SOCS1, LITAF, CIITA); plus new or tenuously associated loci: 2p16 (MSH6), 6q23 (TNFAIP3), 9p22 (CDKN2A/B), 20p12 (PTPN1). Discrete homozygous regions sometimes substituted focal deletions accompanied by gene silencing implying a role for epigenetic or mutational inactivation. Genomic amplifications increasing gene expression or gene-activating rearrangements were respectively rare or absent. Our findings

    The blastic variant (BV) form of mantle cell lymphoma (MCL) is considered to be a very aggressive subtype of non-Hodgkin's lymphoma (NHL). In order to determine its clinico-biological features and response to therapy we studied 33 patients (17%) out of 187 suffering from MCL who were diagnosed with a BV of MCL. Blastic variant wa
