    To study the anatomical and histomorphological pattern of extranodal non Hodgkins lymphoma (NHL). Study Design: Descriptive study Place and Duration of Study: The study was carried out at Oncology department Combined Military Hospital Rawalpindi during July 2012 to April 2013. Materials and Methods: All newly diagnosed patients of NHL with extranodal involvement were included in the study. They were categorized as primary extranodal or secondary extranodal lymphomas. Histological pattern and site of involvement were studied. Results: The male to female ratio was 2.2:1 (Male 31, Female 14), and the mean age was 48.16 years (SD=13.40). Primary extranodal involvement was seen in 55.6% of patients. Secondary extranodal involvement was seen in 44.4% of patients. Diffuse large B-cell lymphoma (DLBCL) was the most common type of NHL observed in both primary and secondary extranodal involvement. Gastrointestinal tract was the most common site for primary extranodal involvement and bone marrow was the most common site for secondary extranodal involvement. Conclusion: High frequency of primary extranodal involvement was noted in our study. DLBCL was the most common morphological type observed. Gastrointestinal tract and secondary bone marrow involvement were the most common anatomical sites for primary and secondary extranodal involvement respectively. (author)

    Malignant lymphomas are differentiated into Hodgkin's and non-Hodgkin's-lymphoma (NHL). The following article discusses the imaging of extranodal NHL in supradiaphragmatic localizations. Lymphoma can affect nearly all tissues, and represent a rare entity as primary extranodal NHL. A secondary involvement of non-nodal tissue as consequence of a generalized lymphoproliferative disease is more common,and may be seen as well in HIV-positive patients defining AIDS. As extranodal lymphoma mimick the radiologic appearance of other malignant tumors, direct diagnosis without histologic analysis is often impossible. The article describes typical manifestations of lymphoma of the lungs, the head and neck area including the large glands, and rare localizations as the heart or the breast. (orig.) [de

    Objective: To review the approach to the diagnosis, classification, assessment, treatment and continuing management of patients with primary extranodal non-Hodgkin's lymphoma, and the management of generalized disease with the emphasis on the current role of salvage treatment with high dose chemotherapy and stem cell/bone marrow support strategies. Non-Hodgkin's lymphoma may involve any part of the body. Many lymphomas, such as MALT, angiocentric T-cell, etc., commonly present in extranodal sites. Lymphomas presenting in the GI tract, and head and neck, are most common with the single most common site being the stomach. Gastric lymphoma is associated with Helicobacter pylorii and is most common in areas endemic for Helicobacter pylorii infection. Recent advances in the understanding of the etiology of gastric MALT, thyroid, and intestinal lymphomas present new opportunities for the application of novel therapeutic approaches e.g. antibiotic therapy for Helicobacter pylori and early stage IPSID. Lymphomas presenting in the orbit, thyroid, breast, bone, extradural and skin are of interest because of the importance of expert RT in securing local control. Primary brain lymphomas present a particular challenge to the radiation oncologist. Although localized, primary brain lymphomas are extremely difficult to control. Rare sites of extranodal lymphoma include testis, female genital tract, and lung. Extranodal lymphomas are often localized and cure with RT or CMT is possible. They represent a assorted group of diseases with diverse presentations, prognosis, sensitivity to RT and expected outcome. They are of particular importance to radiation oncologists as they require special attention to patterns of spread and treatment planning. The principles of management of primary extranodal lymphoma, however, follow those applicable to localized nodal presentations. Although primary extranodal lymphomas are highly curable, a proportion of patients will fail with disseminated

    Full Text Available Abstract Diffuse large B-cell lymphoma usually starts as a rapidly growing mass in an internal lymph node and can grow in other areas such as the bone or intestines. About 1/3 of these lymphomas are confined to one part of the body when they are localized. In the case of a 78-year-old man, an extensive tumour was located on the right thigh. Biopsies of the tumour revealed diffuse proliferation of large lymphoid cells which have totally affected the normal architecture of striated muscle. The patient received multimodality treatment including chemotherapy of the CHOP regimen and adjuvant radiotherapy. Despite this being a fast growing lymphoma, about 3 out of 4 people will have no signs of disease after initial treatment, and about half of all people with this lymphoma are cured with therapy.

    Non-Hodgkin's lymphomas are a varied and complex group of diseases that must be distinguished from Hodgkin's disease. The latter almost always begins in lymph nodes and spreads primarily in an axial fashion; non-Hodgkin's lymphomas may begin either in lymph nodes or in extranodal tissue and can spread both in an axial fashion and centrifugally. Because of changes in pathology terminology and the introduction of a classification using cell surface markers, many prognostic groups of patients with lymphomas have evolved. Therapeutic choices and prognosis are greatly influenced by variations in anatomic sites and extent of disease. Currently, the decisions on management require a balancing of radiation therapy with systemic chemotherapy. In some cases, radiation therapy alone may be sufficient; however, because most patients with non-Hodgkins's lymphomas tend to have advanced disease, a large percentage of patients will be managed with chemotherapy alone or in combination with radiation therapy

    Full Text Available Waldeyer's ring is the primary site of Non-Hodgkin's Lymphoma (NHL involvement in approximately 5 to 10% of all lymphoma patients. Of all Waldeyer's ring NHLs, the tonsil is the most frequent site,followed by the nasopharynx. Lymphomas arising from base of the tongue are less frequent, accounting for 7% of all primary Waldeyer's ring NHLs. The possible differential diagnosisincludes Squamous Cell Carcinoma (SCC, which is the most common malignancy of the tongue base, salivary gland malignancy, (adenoid cystic carcinoma or mucoepidermoidcarcinoma and infection processes, such as tuberculosis. Here we present a case of 43 year old male presenting with mass lesion of the base of tongue and odynophagia. The diagnosis was initially made by ne needle aspiration of this lesion. Subsequent imaging investigations revealed a lobulated mass inltrating bowel loop in the right iliac fossa. Histopathological and immunohistochemistry tests for both lesions conrmed extra-nodal, primary NHL Bcell diffuse, large cell type.

    Extra-nodal lymphomas may arise in any organ, and different histological subtypes occur in distinct patterns. Prognosis and treatment depend not only on the histological subtype and disease extent, but also on the particular involved extra-nodal organ. The clinical course and response to treatment...... for the more common extra-nodal organs, e.g. stomach, Waldeyer's ring, skin and brain, are fairly well known and show significant variation. A few randomised trials have been carried out testing the role of radiotherapy in these lymphomas. However, for most extra-nodal lymphomas, randomised trials have...... not been carried out, and treatment decisions are made on small patient series and extrapolations from nodal lymphomas. Hopefully, wide international collaboration will make controlled clinical trials possible in the less common extra-nodal lymphomas. Modern highly conformal radiotherapy allows better...

    Primary non-Hodgkin's lymphoma occurs quite seldom in the nasopharynx, therefore reports on this topic are rare in medical literature. The treatment results of 30 irradiated patients (40 to 60 Gy) are presented. The period of the study ranges from 1960 to 1985. 13 patients with low grade lymphoma and 17 patients with high grade lymphoma according to the Kiel classification form the basis of this study. The overall actuarial 5-year survival rate is 24%. This also applies for the subgroups of low grade and high grade lymphomas with a 5-year survival rate of 24%, respectively. The evaluation of the patients without generalization in the course of disease shows that the prognosis of stage IE patients with 43% was superior to the one of stage IIE patients with 25% (p [de

    Between January 1986 and August 1993, 63 patients with primary extranodal Non-Hodgkin lymphoma of head and neck region, stages IE and IIE were treated with radiotherapy. The histological classification followed the Kiel classification, staging the Ann Arbor classification. Patient characteristics: 33 Male, 30 female; age 18 to 84 years; tumor localisation: Tonsils 26, nasopharynx 7, oropharynx 8, paranasal sinus 11, salivary glands 7, floor of mouth/gingiva 3, larynx 1. Mean follow-up is 74 months. Low-grade lymphoma in stages I and II CS were treated with definitive radiation therapy according to the concepts of epithelial tumors of the same localisation (target volume and technique).The adjuvant dose was 30 Gy and in the tumor volume 40 Gy, 2 Gy daily. 28 patients were registered, 18 in stage I and 10 in stage II. High-grade lymphoma were treated with definitive radiation therapy according to the concepts of epithelial tumors of the same localisation, too. The dose was 40 respectively 50 Gy, followed by 4 course of adjuvant chemotherapy with CHOP. Thirty-five patients were enrolled, of whom only 10 received chemotherapy. The overall 5-year survical rates were for low-grade 67% and for high grade lymphoma 88%. The corresponding relapse-free survival rates were 54/68%, respectively. Only 1 patient failed within the irradiated target volume. Recurrences occurred at sites distant to the irradiated volume in nodal and extranodal regions. Prognosis was influenced by histologic grade. Significant trends were not observed for other potential pretreatment parameters (age, stage, localisation, bulk). (orig./MG) [de

    Full Text Available Background/Aim. Bronchus-associated lymphoid tissue (BALT lymphoma is a rare subtype of low grade marginal zone B cell lymphoma representing 10% of all MALT lymphomas. The purpose of this study was to analyze the outcome of this group of patients comparing prognostic parameters and therapy modalities. Methods. A total of eight patients with BALT lymphoma had diagnosed between January 1998 - April 2008 at the Institute of Hematology, Clinical Center of Serbia, Belgrade, and they were included in this retrospective analysis. Results. Male/female ratio was 2/6, the median age was 64 years (range 37-67 years. Six patients had nonspecific respiratory symptoms and all of them had B symptoms. The patients were seronegative for HIV, HCV and HBsAg. Three patients had Sjogren's syndrome, rheumatoid arthritis and pulmonary tuberculosis, respectively. Seven patients were diagnosed by transbronchial biopsy and an open lung biopsy was done in one patient. Patohistological findings revealed lymphoma of marginal zone B cell lymphoma: CD20+/CD10-/CD5-/CyclinD1- /CD23-/IgM- with Ki-67+<20% of all cells. According to the Ferraro staging system, five patients had localized disease (CS I-IIE and three had stage IVE; bulky tumor mass had 3 patients. All patients had Eastern Cooperative Oncology Group (ECOG performance status (PS 0 or 1. Five patients received monochemotherapy with chlorambucil and 3 were treated with CHOP regimen (cyclophosphamide, doxorubicin, vincristine and prednisone. A complete response (CR was achieved in 5 patients and a partial response (PR in 3 of them, treated with chlorambucil monotherapy and CHOP regimen. All patients were alive during a median follow-up period of 49 months (range 6- 110 months. Three patients relapsed after monochemotherapy into the other extranodal localization. They were treated with CHOP regimen and remained in stable PR. Conclusion. BALT lymphoma tends to be localised disease at the time of diagnosis, responds well

    Follicular non-Hodgkin's lymphoma (NHL) is a unique subtype of NHL, which is indolent, incurable with a high prevalence of residual mass after treatment, and may transform to more aggressive NHL. The aim of this review is to (1) describe the histological and flow cytometry characteristics of follicular NHL; (2) introduce the Follicular Lymphoma International Prognostic Index 2 (FLIPI-2), which allows better treatment selection and patient stratification for clinical trials; (3) illustrate the classic and atypical ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and positron-emission tomography (PET)/CT appearance of follicular NHL; and (4) characterize the appearance of nodal and extranodal follicular NHL with pathological correlation. Imaging is essential in every step of the management of patients with follicular lymphoma. Overall survival is improved with better predictive tools and new targeted biological therapies. Radiologists should be aware of possible active residual mass, indolent recurrence, transformation, and association with other primary cancers in patients treated for follicular lymphoma.

    Full Text Available Objective: Our aim was evaluate the role the PET/CT in the assessment of response to therapy in patients with Non-Hodgkin extra-nodal lymphoma: in particular, a five-point scale (Deauville criteria, which can be employed for early- and late-therapeutic response assessment. Methods: Sixty patients with pathologically confirmed Non-Hodgkin lymphoma (NHL were enrolled in this prospective study. All patients underwent the following PET/CT examinations: initial PET/CT for staging, interim PET/CT and end of treatment PET/CT. Response assessment was done using new Cheson’s guidelines and five-point scale (Deauville criteria. Results: All patients were evaluated for response to therapy in the early interim, followed by late interim, as well as end treatment assessment for the overall response. We found good concordance of response assessment according to the Deauville criteria classification with International Harmonization Project (IHP classification. After early interim 48/60 patients had concordant designations (91.7%, 83.3%, 70%, and 33.3% and 12 patients had discordant designations. After late interim, 56/60 patients had concordant designations (100%, 100%, 80%, and 50% and four patients had discordant designations. After end of treatment, 54/60 patients had concordant designations (100%, 100% and 71.4% and six patients has discordant designations. Conclusion: Response assessment according to the Deauville criteria classification showed good concordance with IHP classification. According to our findings, we recommend the use of Deauville criteria in reporting of PET/CT for staging and assessment of response to treatment.

    Non-Hodgkin's lymphomas are a heterogeneous group of malignancies of the lymphoid system. The exact etiology for most lymphomas has not been determined, but both viral and bacterial infections have been shown to be important etiologic factors. The WHO classification of hematopoietic and lymphoid tumours classifies lymphomas into B-cell and T-cell neoplasms. B-cell lymphomas account for more than 85% of all lymphomas. The Ann Arbor staging classification has been adopted by the AJCC and UICC as a standard for classifying extent of anatomic disease. The two most common histologic disease entities are follicular lymphomas and diffuse large B-cell lymphomas. The management of follicular lymphomas is used as a paradigm for the management of all indolent lymphomas. Radiation therapy is used for stage I and II disease, while alkylating agent chemotherapy, immunotherapy and radioimmunotherapy are most frequently used in stage III and IV disease that requires treatment. Most patients with follicular lymphoma enjoy prolonged survival, but at present there is no evidence that those with stage III and IV follicular lymphoma can be cured. Diffuse large B-cell lymphomas serve as a paradigm for treating aggressive lymphomas. Stage I and II diffuse large cell lymphomas are generally treated with combined modality therapy with doxorubicin-based chemotherapy followed by involved field radiation therapy, while those with stage III and IV disease are treated with chemotherapy alone. Patients who fail initial management are treated with further chemotherapy. High-dose chemotherapy with stem cell rescue has been shown to be particularly effective as salvage treatment for diffuse large cell lymphomas. The management of a heterogeneous group of primary extranodal lymphomas in general follows the above treatment principles, with additional treatment being required for those with a high risk of CNS failures, or involvement of contralateral paired organs. The management of MALT lymphomas

    duration of chemotherapy is related to the bulk of tumour at presentation and anatomic extent of the disease. The recently completed ECOG randomized trial of chemotherapy and radiation versus chemotherapy alone confirmed benefit of RT in the localized lymphomas. Non-Hodgkin's lymphoma may involve any part of the body. Presentation in extranodal sites is common. Primary extranodal lymphomas are often localized, highly curable with RT or combined modality therapy. These diseases are of particular importance to radiation oncologists as they require a special attention to patterns of spread and treatment planning. However, the principles of management of extranodal lymphoma follow those applicable to nodal presentations

    Full Text Available Non-Hodgkin's lymphomas are extremely rare among all tumors of female reproductive system. Diagnostic mistakes and inadequate therapeu- tic tactics in these diseases are results of usual absence of alertness of gynecologists. The aims are to analyze reasons of diagnostic mistakes in patients with non-Hodgkin's lymphomas of female reproductive system and to discover definitive clinical and morphological characteristics of female reproductive system lymphoid tumors. During the period between 1989 and 2006, 305 cases of primary extranodal non-Hodgkin's lym- phomas were detected; female reproductive system was affected in 7% of patients (totally 40 patients, which were included in investigated group. In the whole analyzed group of women (n=40, median age 43 yrs, range 17-84 yrs, patients with primary lesion of female reproductive system had median age of 40 yrs and with secondary involvement - 46 yrs. Most of patients were fertile (60%, n=24. Such tumors was localized in breast in 40% of cases (n=16, in ovaries - 20% (n=8, in uterine corpus - 12,5% (n=5, in uterine cervix - 15% (n=6, and in vagina - remaining 12,5% (n=5. Average time from diagnosis to beginning of the treatment was 7,5 months. As a result, the onset of specific therapy was delayed in 65% cases (n=26 and 50% (n=20 underwent unneeded surgery. Diagnostic mistakes lead to inadequate treatment. Extranodal non-Hodgkin’s lymphomas of female reproductive system, both primary and secondary, are rare pathology. Primary lesion is more typical for older women, sec- ondary is mainly affecting younger women (in reproductive period. Chemotherapy response and prognosis are better in primary cases.

    Optimal lymphoma management requires accurate pretreatment staging and reliable assessment of response, both during and after therapy. Positron emission tomography with computerized tomography (PET/CT) combines functional and anatomical imaging and provides the most sensitive and accurate methods...... for lymphoma imaging. New guidelines for lymphoma imaging and recently revised criteria for lymphoma staging and response assessment recommend PET/CT staging, treatment monitoring, and response evaluation in all FDG-avid lymphomas, while CT remains the method of choice for non-FDG-avid histologies. Since...... interim PET imaging has high prognostic value in lymphoma, a number of trials investigate PET-based, response-adapted therapy for non-Hodgkin lymphomas (NHL). PET response is the main determinant of response according to the new response criteria, but PET/CT has little or no role in routine surveillance...

    From 1972 to 1982, 563 patients with Stage I and II non-Hodgkin's lymphoma received radiation therapy in the department of radiology which belongs to the JLRTS group. Local control failures were seen in only 5 cases (0.9 %). The regional recurrences were found in 30 cases (5 %). 17 of recurrences occured during the first 5 years. 17 cases had remissions again, and 5 cases had 5 year survivals. (author)

    The role of radiotherapy in the treatment of nodal non-Hodgkin's lymphoma has been modified by the introduction of efficient chemotherapy and the development of different pathological classifications. The recommended treatment of early-stage aggressive lymphomas is primarily a combination chemotherapy. The interest of adjuvant radiotherapy remains unclear and has to be established through large prospective trials. If radiation therapy has to be delivered, the historical results of exclusive radiation therapy showed that involved-fields and a dose of 35-40 Gy (daily fraction of 1.8 Gy, 5 days a week) are the optimal schedule. The interest of radiotherapy in the treatment of advanced-stage aggressive lymphoma is yet to be proven. Further studies had to stratify localized stages according to the factors of the International Prognostic Index. For easy-stage low-grade lymphoma, radiotherapy remains the standard treatment. However, the appropriate technique to use is controversial. Involved-field irradiation at a dose of 35 Gy seems to be the optimal schedule, providing a 10 year disease-free survival rate of 50 % and no major toxicity. There is no standard indication of radiotherapy in the treatment advanced-stage low-grade lymphoma. For 'new' nodal lymphoma's types, the indication of radiotherapy cannot be established (mantle-zone lymphoma, marginal zone B-cell lymphoma) or must take into account the natural history (Burkitt's lymphoma, peripheral T-cell lymphoma) and the sensibility to others therapeutic methods.

    Peritoneal spread of non-Hodgkin lymphoma is rare: fewer than three percent of persons afflicted with this disease develop peritoneal spread. Pericardial involvement by non-Hodgkin lymphoma is equally rare. We report an instance of peritoneal and pericardial spread in a patient with non-Hodgkin lymphoma that was detected only by CT scan. The peritoneal lesions were not visible by ultrasound examination. A pertinent review of the literature is presented. (author)

    2002-09-01

    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.

    The clinical course and biopsy specimens from 515 consecutive non-Hodgkin's lymphoma patients was evaluated retrospectively in an attempt to determine the clinical importance of documented changes in histology over time. Two-hundred and five of these patients has an initial diagnosis of nodular lymphoma and were reviewed for this anaysis. Sixty-three underwent a repeat biopsy greater than 6 mo after initial diagnosis. In 23 patients, these repeat biopsies revealed a change in histology to a diffuse pattern and/or a change to a larger ''histiocytic'' cell type, while repeat biopsies for the other 40 (63%) disclosd persistence of a nodular pattern and no clear change in basic cell type. Progression from nodular lymphoma to diffuse histiocytic, mixed, or undifferentiated types of lymphomas of Rappaport was found in repeate biopsies obtained from 19 patients (30%). Prognosis for survival following a biopsy that demonstrated histologic change was related to the histology demonstrated at the most recent biopsy and to the response to subsequent drug treatment. Survival following repeat biopsy for these 19 patients was significantly shorter than for the 40 patients whose histology remained nodular (p < 0.001). However, attainment of a complete remission with intensive combination chemotherapy was associated with prolonged survival in eight patients and prolonged disease-free survival in one patient. Since prior treatment may compromise the ability to achieve a complete response to chemotherapy in patients with nodular lymphoma who develop an aggressive diffuse histology, the likelihood of histologic progression must be considered in the design of future clinical trials in nodular lymphoma. Histologic progression does not preclude attainment of a complete response to intensive chemotherapy

    Full Text Available Diffuse large-cell B lymphoma of the pancreas is a rare disease, representing less than 1% of all non-Hodgkin's lymphomas and less than 0.9% of all malignant tumors of the pancreas. About 150 cases of the disease have been observed so far. The tumors are more frequent in the head of the pancreas then in other parts of the organ. They are usually larger (average size of 8 cm and are non-resectionable. As a rule, exact diagnosis is based on the histology and the immunohistology of the specimen taken during open surgery performed for general diagnosis of the pancreatic tumor. Very rarely can a very reliable and experienced cytopathologist establish a proper diagnosis based on material obtained from a fine needle biopsy. The disease usually responds positively to immunochemotherapy according to protocol R-CHOP. Occasionally, additional radiotherapy may be required. We present two women, 66 and 49 years old, in whom a diagnosis of large-cell B lymphoma of the pancreas was established, based on the histology and the immunohistochemistry of a specimen taken during open surgery performed in order to remove pancreatic tumors, which turned out to be non-resectionable. After immunochemotherapy, the symptoms disappeared and the tumors shrank, in one patient after additional radiotherapy. The authors would like to point out the importance of a proper histological diagnosis, which permitted the application of immunochemotherapy alone or together with additional radiotherapy with at least temporarily favorable results.

    Thirty-two confirmed cases of non -Hodgkin's lymphoma (NHL) were examined for cutaneous manifestations for a period of 2 years from November 1998 in KMC Hospital Attavar, Mangalore. Cutaneous manifestations in the study group were compared to a control group of 32 patients. Specific infiltrates were present in all (5/5) CTCL patients and one out of twenty-seven patients with low grade NHL. Morphologically they presented as papules, plaques, nodules and erythroderma. Infective conditions seen in the study group were superficial fungal (7/32) and viral infections (2/ 32). Non-infective conditions were acquired ichthyosis (10/32), generalised pruritus (5/32), insect bite reaction (1/32) and drug eruption (1/32). When compared to control patients only acquired ichthyosis and generalised pruritus were found to be statistically significant. The study group also showed changes due to chemotherapy like diffuse alopecia (24/29), bluish pigmentation of proximal part of nail (4/29), localised pigmentation of palms and soles (1 /29), diffuse pigmentation at injection site (1 /29), pigmentation at scar site (1 /29) and stomatitis (4/29).

    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

    Lymphomas are classified based on the normal counterpart, or cell of origin, from which they arise. Because lymphocytes have physiologic immune functions that vary both by lineage and by stage of differentiation, the classification of lymphomas arising from these normal lymphoid populations is complex. Recent genomic data have contributed additional complexity. Areas covered: Lymphoma classification follows the World Health Organization (WHO) system, which reflects international consensus and is based on pathological, genetic, and clinical factors. A 2016 revision to the WHO classification of lymphoid neoplasms recently was reported. The present review focuses on B-cell non-Hodgkin lymphomas, the most common group of lymphomas, and summarizes recent changes most relevant to hematologists and other clinicians who care for lymphoma patients. Expert commentary: Lymphoma classification is a continually evolving field that needs to be responsive to new clinical, pathological, and molecular understanding of lymphoid neoplasia. Among the entities covered in this review, the 2016 revision of the WHO classification particularly impact the subclassification and genetic stratification of diffuse large B-cell lymphoma and high-grade B-cell lymphomas, and reflect evolving criteria and nomenclature for indolent B-cell lymphomas and lymphoproliferative disorders.

    Computer Tomographic (CT) study is crucial for defining distribution, characteristics and staging of primary gastrointestinal lymphomas. The presence of multifocal sites, the wall thickening with diffuse infiltration of the affected gastrointestinal (GI) segment in association with regional adenopathies, permit the orientation of the CT diagnosis for primary GI lymphomas. The gold standard for diagnosis remains, in all cases of digestive tract non-Hodgkin lymphomas (NHL), the histological examination, which allows a tissue diagnosis, performed preferably by transmural biopsy.

    BACKGROUND: Non-Hodgkin lymphoma has increased in frequency over the past 30 years, and is a common cancer in HIV-1-infected patients. Although no definite risk factors have emerged, a viral cause has been postulated. Polyomaviruses are known to infect human beings and to induce tumours in laboratory animals. We aimed to identify which one of the three polyomaviruses able to infect human beings (simian virus 40 [SV40], JC virus, and BK virus) was associated with non-Hodgkin lymphoma. METHODS: We analysed systemic non-Hodgkin lymphoma from 76 HIV-1-infected and 78 HIV-1-uninfected patients, and non-malignant lymphoid samples from 79 HIV-1-positive and 107 HIV-1-negative patients without tumours; 54 colon and breast carcinoma samples served as cancer controls. We used PCR followed by Southern blot hybridisation and DNA sequence analysis to detect DNAs of polyomaviruses and herpesviruses. FINDINGS: Polyomavirus T antigen sequences, all of which were SV40-specific, were detected in 64 (42%) of 154 non-Hodgkin lymphomas, none of 186 non-malignant lymphoid samples, and none of 54 control cancers. This difference was similar for HIV-1-infected patients and HIV-1-uninfected patients alike. Few tumours were positive for both SV40 and Epstein-Barr virus. Human herpesvirus type 8 was not detected. SV40 sequences were found most frequently in diffuse large B-cell and follicular-type lymphomas. INTERPRETATION: SV40 is significantly associated with some types of non-Hodgkin lymphoma. These results add lymphomas to the types of human cancers associated with SV40.

    Lymphomas are the most common non-epithelial tumors of the head and neck and its incidence has increased in recent decades. Around 10% are extranodal lymphomas, and in more than half of the cases are located in Waldeyer's lymphatic ring. The most common presenting symptoms are odynophagia and dysphagia (68%), and symptoms suggestive of oropharyngeal cancer such as cough, hoarseness, earache, feeling of occupation in the back of the mouth, throat or neck. In non-Hodgkin lymphomas in this location, B symptoms (weight loss, fever and sweating) are rare (5%). The histological subtype of each individual lymphoma affects the evaluation, therapy and prognosis. Copyright © 2012 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

The estimated 5 and 10-year disease-free survival rates (DFS) were 63% and 60% and the survival rates at 5 and 10 years 82% and 76% respectively. Lymphomas arising from gut-associated lymphoid tissue, i.e. Waldeyer's ring, the thyroid and the gastrointestinal tract had a more favourable clinical course (10-year projected DFS 83%) than nodal (50%) and other extranodal lymphomas. Although the number of patients with other extranodal sites was small, sites such as testis, nasal cavity, paranasal sinus and extradural space seemed to have a high relapse rate. Unfavourable clinical courses were also observed among nodal high-grade NHL if the lymph nodes were larger than 5 cm in diameter. Chemotherapy before radiotherapy may be recommended in NHL subgroups with a high relapse rate and which today are potentially curable with chemotherapy, i.e. high-grade NHL. This study indicates that large nodal lymphomas and some extranodal sites belong to this group. (orig.)

    Objective: To analyze the frequencies of histological types of lymphoma, diagnosed with complete immunohistochemical profile in younger and older age group. Study Design: Cross-sectional analytical study. Place and Duration of Study: Dow Diagnostic Research and Reference Laboratory, Dow University of Health Sciences, Karachi, from January 2009 to September 2013. Methodology: Consecutive cases of lymphomas, which were diagnosed using immunohistochemistry, were analyzed according to WHO classification. Frequency and percentages for different types of lymphomas were calculated. Hodgkin and non-Hodgkin lymphomas characteristics in two age groups of less than and more than 40 years were compared, applying chi-square test. Results: Out of the 318 cases, 79 (25 percentage) were Hodgkin Lymphomas (HL) and 239 (75 percentage) were Non-Hodgkin Lymphomas (NHL). Mixed Cellularity Hodgkin Lymphoma (MCHL) was the commonest (n=48). Amongst the NHL, 215 (89.95 percentage) were B cell lymphomas and 24 (10.05percentage) were T-cell lymphomas. Diffuse Large B-Cell Lymphoma (DLBCL) was the commonest lymphoma (n=165, 69.95 percentage of NHL). Anaplastic T-Cell Lymphoma (ALCL, n=10) was the commonest T-cell lymphoma. The frequency of HL was significantly higher in the younger age group and that of NHL was higher in the older age group (p < 0.001). Primary lymph node involvement was reported in 175 (55 percentage) and cervical lymph node was the most frequent site. Extra nodal involvement was seen in 93 (29 percentage) of all cases and was reported in 87 (36.4 percentage) of NHL and 6 (7.5 percentage) of HL. The most common extra nodal site was the gastrointestinal tract. Conclusion: Hodgkin lymphoma comprises 25 percentage and non-Hodgkin lymphoma comprises 75 percentage of all lymphomas. Both occur in younger age groups than reported in the West. B-cell NHL is three times more common than T-cell lymphoma. DLBCL is the most frequent lymphoma. ALCL is the most common T-cell, and mixed

    Objective: To analyze the imaging manifestations of primary non-Hodgkin lymphoma of skeletal muscle and improve the recognition of this rare disease. Methods: Five cases of primary non- Hodgkin lymphoma of skeletal muscle proved pathologically underwent imaging exam, including MRI and CT in 3 cases, only MRI in 1 case, only CT in 1 case, X-ray in 2 cases and bone scintigraphy in 2 cases. Results: Diffuse enlargements of involved muscle with presentation of overall configuration were observed in all five cases. All 4 cases manifested as homogeneous soft masses, which is isoattenuating to normal muscle on unenhanced CT images. After intravenous injection of contrast media, the masses enhanced homogeneously and slightly (2 cases) or moderately (1 case) on CT images. The lesions were homogenous and had isointense or slightly low signal intensity compared with that of uninvolved muscle on T 1 -weighted images and high signal intensity on T 2 -weighted images. After intravenous injection of contrast media, all 2 cases enhanced homogeneously and moderately with the enhanced signal intensity of involved muscle greatly higher than that of uninvolved muscle on MR images. Two cases of X-ray plain showed no destruction of bone and 2 cases of bone scintigraphy exams showed increased radiotracer uptake of involved muscle with no infiltration of bone marrow. Conclusion: There are several characteristics on the imaging of primary non-Hodgkin lymphoma of skeletal muscle. MRI is the optimal imaging method for the diagnosis of this disease. (authors)

    To describe the characteristics of CT findings in nasal lymphoma. We retrospectively reviewed CT findings and pathologic findings of eight patients (six males and two females) aged between 24 and 68 years with pathologically-proven nasal lymphoma. We analyzed mass location, laterality, size, margin, mass effect, adjacent bony change and contrast enhancement pattern. All eight cases were non-Hodgkin's lymphoma, intermediate grade, diffuse large cell type. Seven cases were B-cell type and one was T-cell. In all cases, tumors were located in the medial wall of the inferior turbinate. In four cases, they were also found in the anterior ethmoidal sinus, and in one case, in the nasal septum. The mean size of the main mass was 3.3cm. In seven cases, tumors were unilateral (one on the right; six on the left), and in the remaining case, bilateral. In six cases tumor margin was smooth and in two cases focal nodularity was seen. In two cases there was no bony change, and in four, there was mucosal thickening along the nasal septum; in one of these four, minimal bony erosion was also found. In the other two cases, bony destruction was seen, and tumors were very large(7cm in diameter) or bilterally located. In three cases, the nasal septum was displaced by the mass. In all cases with bony change, the nasal septum was involved. All tumors were homogeneously well enhanced after IV contrast administration. The main CT findings of nasal non-Hodgkin's lymphoma were smooth margin, unilateral location (mainly in the medial wall of the inferior turbinate and growing to the medial side without bony destruction) mucosal thickening along the nasal septum and clear homogeneous enhancement after IV contrast administration. These characteristics will help diagnosis, help deter-mine the appropriate region for radiation and other appropriate therapy, and facilitate prognosis in patients with nasal non-Hodgkin's lymphoma.

    A total of 98 patients with malignant tumors of the tonsil (Squamous cell carcinoma, 34 patients, Non-Hodgkin's lymphoma, 64 patients) werw treated with radiation therapy between 1962 and 1979 at the National Cancer Center Hospital. All were staged by the TNM system, using UICC Classification 1978. With regard to stage distribution, Stage III is most frequent (47.1 %) in squamous cell carcinoma, Stage IV is most frequent (48.4 %) in Non-Hodgkin's lymphoma. Much more advanced cases were included in Non-Hodgkin's lymphoma. Five year survival rate for patients with squamous cell carcinoma and Non-Hodgkin's lymphoma were 49 % and 62 %, respectively. 50 % survival months with squamous cell carcinoma and Non-Hodgkin's lymphoma were 58.7 months and 195.5 months, respectively. Better prognosis was observed in Non-Hodgkin's lymphoma than squamous cell cacinoma. (author)

    Full Text Available The head and neck is the second most common region for extranodal lymphomas. The most common site is the Waldeyer's ring, and involvement of the base of tongue is extremely rare. We present a rare case of a young female with primary non-Hodgkin's lymphoma (NHL of the base of tongue. A 23-year-old female presented with a history of foreign body sensation in her throat for a month. Oral examination revealed a lobulated smooth mass at the base of tongue. Contrast-enhanced computed tomography neck shows polypoidal homogeneously enhancing soft tissue lesion in the base of tongue extending till the lateral pharyngeal wall. The biopsy of the lesion was reported as NHL. Hodgkin's lymphoma should be kept in the differential diagnosis of swelling arising from the base of tongue. We report a rare and varied presentation of extranodal lymphoma. A careful clinical evaluation supported by histopathological and radiologic investigations will help in identifying the disease at an early stage, resulting in a better prognosis.

    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.......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]).

    Full Text Available Abstract 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.

    Mediastinal non-Hodgkin's lymphoma in children is known to have an adverse prognosis, that is called ''lymphoblatic lymphoma''. Recently, chemotherapy for leukemia using multiple agents has been applied for non-Hodgkin's lymphoma in children, and this has improved relapse-free survival. Radiotherapy has been employed in order to reduce local recurrence. Two children received whole thoracic irradiation (10 Gy) who had mediastinal mass with malignant pleural effusion, then control of the effusion was achieved. Thereafter, radiation field was decreased in size to mantle field, and main tumor was treated to 30 Gy. In the course of treatment, mediastinal tumor was disappeared. Thereafter, radiation field was decreased in size to mantle field, and main tumor was treated to 30 Gy. In the course of treatment, mediastinal tumor was disappeared. For one child with only a mediastinal mass, mantle field was employed. He was treated to 30 Gy with chemotherapy. but he had CNS relapse. CNS prophylaxis is of considerable importance in this lymphoma according to the protocol of leukemia. (author)

    In an attempt to evaluate characteristic CT features of primary pancreatic involvement in non-Hodgkin lymphoma (NHL), scans of 10 patients were reviewed retrospectively and compared to 50 patients with histologically proved different neoplasms of the pancreas. Setting the correct diagnosis of NHL would be essential for planning of treatment and prognosis. CT findings of NHL were characteristic but not specific. Nevertheless, the presence of a homogeneous pancreatic mass with a diameter of 7 cm or more, infiltrating surrounding tissue accompanied by retroperitoneal and/or mesenteric lymphadenopathy strongly suggests NHL. CT-guided needle biopsy can help to establish the diagnosis of pancreatic NHL. (orig.)

We report a case of a 17-year-old teenager who presented with a 2-month-old ulcerous vegetant lesion in the right inguinal region. The patient was diagnosed with LGV and received erythromycin treatment. Three months after treatment, he presented with a new ulcerous lesion, very similar to the previous one, in the right supraclavicular region. He was diagnosed with a diffuse large B-cell non-Hodgkin lymphoma. Both diseases are rare in Rio de Janeiro City, Brazil, and physicians should not neglect the possibility of STDs in such cases.

    In this retrospective study, 470 patients with non-Hodgkin's lymphoma (NHL) who had been followed in the Hacettepe University Medical Oncology Department between 1973 and 1990, were evaluated to establish their epidemiologic, clinical and therapeutic characteristics. Out of 470 patients, 302 (62.2%) were male and 168 (37.8%) were female. The ages ranged from 16 to 85, with a median of 44 years. Constitutional symptoms were present in 46.4% of the patients. According to the Working Formulation, low, intermediate, and high-grade lymphomas comprised 33.4%, 54.9%, and 12.7%, respectively. The most common extranodal presentation was gastrointestinal. The chemotherapy regimens most commonly used were CVP (cyclophosphamide, vincristine, prednisone), BCNOP (bleomycin, cyclophosphamide, mitoxantrone, vincristine, prednisone), CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) and CHOP-Bleo (cyclophosphamide, doxorubicin, vincristine, prednisone, bleomycin). The response rates and the survival figures attained with these regimens were not statistically significantly different (P > 0.05). In the Cox multivariate model, pathologic grade, leukopenia, responsiveness to chemotherapy, bone marrow involvement and age were the important factors influencing the disease-free survival, while responsiveness to chemotherapy, age, presence of constitutional symptoms, pathologic grade, extranodal presentation and stage were the important factors influencing the overall survival. The distribution of NHL according to grade and stage was similar to that in western societies, while constitutional symptoms and lymphomas of the small intestine including immunoproliferative small intestinal disease were more common in Turkey.

    Objective. To evaluate the signal characteristics of primary non-Hodgkin's lymphoma of bone on MRI. Designs and patients. Ten patients with primary non-Hodgkin's lymphoma of bone were included in the study. T1- and T2-weighted imaging was performed. The signal intensity of the lesions was compared with that of the surrounding muscle. Results. The results of the MRI were compared with the histological findings. In the majority of cases (5/10) the lesion involved the femur. In one case each the tibia, humerus, ileum, sacrum, and skull, respectively, were affected. A soft tissue mass was present in four cases. In nine of ten cases on T1-weighted imaging the lesion was hypointense. On T2-weighted imaging seven of ten lesions were hypointense compared with muscle, one isointense and, in two cases, part of the lesion showed slightly hyperintense signal. In all ten cases the signal pattern appeared inhomogeneous. Pathological examination showed extensive fibrosis in the majority of cases. Conclusion. According to our results there is decreased signal intensity of bone marrow on both T1- and T2-weighted imaging, unlike other primary round cell tumors of bone. Because the diagnoses were established with small tissue biopsies, the reason for these findings is speculative. (orig.)

    2007-03-01

    Exposure to benzene, an important industrial chemical and component of gasoline, is a widely recognized cause of leukemia, but its association with non-Hodgkin lymphoma (NHL) is less clear. To clarify this issue, we undertook a systematic review of all case-control and cohort studies that identified probable occupational exposures to benzene and NHL morbidity or mortality. We identified 43 case-control studies of NHL outcomes that recognized persons with probable occupational exposure to benzene. Forty of these 43 (93%) studies show some elevation of NHL risk, with 23 of 43 (53%) studies finding statistically significant associations between NHL risk and probable benzene exposure. We also identified 26 studies of petroleum refinery workers reporting morbidity or mortality for lymphomas and all neoplasms and found that in 23 (88%), the rate of lymphoma morbidity or mortality was higher than that for all neoplasms. A substantial healthy-worker effect was evident in many of the studies and a comprehensive reevaluation of these studies with appropriate adjustments should be undertaken. Numerous studies have also reported associations between benzene exposure and the induction of lymphomas in mice. Further, because benzene is similar to alkylating drugs and radiation in producing leukemia, it is plausible that it might also produce lymphoma as they do and by similar mechanisms. Potential mechanisms include immunotoxicity and the induction of double-strand breaks with subsequent chromosome damage resulting in translocations and deletions. We conclude that, overall, the evidence supports an association between occupational benzene exposure and NHL.

    Objective: To explore and evaluate MRI in diagnosing primary muscle non-Hodgkin lymphoma. Methods: Six surgically confirmed primary muscle non-Hodgkin lymphoma underwent MR examination including T 1 WI, T 2 WI and T 1 WI enhanced studies. The acquired images date was reviewed and analysed retrospectively in comparison with surgical and pathological results. Results: The locations of 6 cases were cervical part (2), upper extremity (1), lower extremity (3), respectively. All cases involved of more than one anatomical compartment with poorly defined solid masses in 5 cases and well defined in 1 cases, 5 extended to subcutaneous fat and 3 extended along the neurovascular bundle. The mean tumor diameter was 13.9 cm, ranging from 7.3 to 22.5 cm. One was well demarcated and 5 were ill-defined. On T 1 WI, 2 were slightly high signal intensity and 4 were slightly low signal intensity. On T 2 WI, 2 were slightly high signal intensity, 3 were intermediate signal intensity and 1 was high signal intensity. Five were inhomogeneous and 1 was homogeneous. The intrinsic structure such as muscle fiber, tendo, spatium intramuscular were detected on 5 cases. Of the 5 dynamic contrast-enhanced cases, it showed moderate enhancement during arterial phase, 2 were homogeneous and 3 were inhomogeneous. And it showed progressive enhancement during interstitial phase, 3 were homogeneous and 2 were inhomogeneous. Conclusions: Primary muscle lymphoma always originated deep to the fascia showing subcutaneous extension and multiple compartment invasion. Typically from poorly defined solid masses with slightly high in signal intensity on MR T 2 WI and middle degree dynamic delayed contrasted-enhanced in which intrinsic anatomic structure such as muscle fiber, tendo, spatium intramuscular and so on can be discerned, almost all cases involve more than one muscle compartment and some of tumor extend along the neurovascular bundle.

    With approximately 10000 cases per year in France, non-Hodgkin's lymphoma (NHL) represents the most frequent hematological malignancy, and 5 to 10 % of new cases of cancers. NHLs constitute a heterogeneous group of lympho-proliferative diseases, including entities with very different epidemiological and evolutive characteristics, as well as prognosis and treatments. Several classifications exist, but in practice, we individualize aggressive NHL including Diffuse Large B-Cell Lymphomas (DLBCL) which is the most common lymphoma, and indolent NHL including follicular lymphomas and mucosa-associated lymphoid tissue (MALT) lymphomas. The role of the radiotherapy in the management of NHLs varies according to the specific sub-type of lymphoma, but it has become increasingly limited over time. Overall it finds indications with curative intent only in situations of localized LMNH: either associated with chemotherapy as part of a combined modality therapy as for the treatment of localized DLBCL, or as exclusive treatment specially in the rare situations of localized follicular lymphomas. Moreover, lymphocytes being extremely radiosensitive cells, radiotherapy retains excellent indications with palliative intent for the management of symptomatic bulky tumor masses, and that whatever the sub-type of NHLs may be. It is important to remember that even today the 'Involved Field' irradiation type remains the gold standard for the treatment of nodal NHLs, even if we witness at present the emergence of new types of irradiation, which aim to reduce the amount of irradiated tissues to try to limit the risks of delayed radio-induced complications. The purpose of this article is to clarify the specific aspects (epidemiological, radio-anatomical and prognostic characteristics) of each NHLs'sub-types (except primary central nervous system lymphomas), as well as the practical modalities of the irradiation (illustrated by a clinical case record) when an indication of

    Full Text Available Abstract Introduction Pituitary adenomas represent the most frequently observed type of sellar masses; however, the presence of a rapidly growing sellar tumor, diabetes insipidus, ophthalmoplegia and headaches in an older patient strongly suggests metastasis to the pituitary. Since the anterior pituitary has a great reserve capacity, metastasis to the pituitary and pituitary involvement in lymphoma are usually asymptomatic. Whereas diabetes insipidus is the most frequent symptom, patients can present with headaches, ophthalmoplegia and bilateral hemianopsia. Case presentation A 70-year-old woman with no previous history of malignancy presented with headaches, right oculomotor nerve palsy and diabetes insipidus. As magnetic resonance imaging revealed a sellar mass involving the pituitary gland and infundibular stalk, which also extended into the right cavernous sinus and sphenoid sinus, the patient underwent an immediate transsphenoidal decompression surgery. Her prolactin was 102.4 ng/ml, whereas her gonadotropic hormone levels were low. A low level of urine osmolality after overnight water deprivation, along with normal plasma osmolality suggested diabetes insipidus. Histological examination revealed that the mass had been the infiltration of a high grade B-cell non-Hodgkin's lymphoma involving respiratory system epithelial cells. Paranasal sinus computed tomography scanning and magnetic resonance imaging of the thorax and abdomen were performed. Since magnetic resonance imaging did not reveal any abnormality, after paranasal sinus computed tomography was performed, we concluded that the primary lymphoma originated from the sphenoid sinus and infiltrated the pituitary. Chemotherapy and radiotherapy to the sellar area were planned, but the patient died and her family did not permit an autopsy. Conclusion Lymphoma infiltration to the pituitary is difficult to differentiate from pituitary adenoma, meningioma and other sellar lesions. To plan the

    Full Text Available Non-Hodgkin's lymphomas (NHLs embody a diverse group of malignancies that originate from the lymphoid system. NHL often exhibit in an extranodal pattern, pertaining to the head and neck region. Intraoral sites are much less frequent, accounting for approximately 3.5% of all oral malignancies. Although the exact cause of NHL still remains inconspicuous, however, research has focused on some factors that may contribute to the development of lymphoma, including genetic factors, impaired immune system and viruses, such as HIV or EBV. Clinically, the bony lesion may present as localized or diffuse swelling, with low-grade pain, sweating, unexplained weight loss, fever, etc. Radiographically, these lesions resemble osteomyelitis or other malignancies creating a diagnostic dilemma. Microscopically, diffused lymphomas consist of large tumor cells with large nuclei that are more than twice the size of lymphocytes which may either exhibit centroblastic or immunoblastic features. Here, we report a rare case of NHL affecting the jaws of a 60-year-old male patient.

    The incidence of Non-Hodgkin's lymphomas (NHL) is rising worldwide and if not adequately treated carries a high mortality rate. The pattern and frequency of NHL vary in different populations and geographical regions. It has considerable biologic and clinical heterogeneity and a definitive diagnosis can be made only after histopathogical examination. The histology and the extent of the lymphoma are the major determinants of optimal therapeutic regimen and treatment outcome. Additionally, the overall treatment strategies should be tailored according to medical status and preference of the patient. A holistic approach provided by a multi-disciplinary team of health care professionals is the cornerstone of ensuring successful treatment outcome. Importantly, therapy should be expedited and where possible performed in experienced centers. Patients achieving remission would require long-term monitoring for disease recurrence and late effects of cytotoxic chemotherapy and radiotherapy. Hence, clinicians should have a fundamental understanding in the biology and the principles of treatment of NHL. This review provides an evidence-based and systematic approach in designing therapeutic strategies for individual patients with newly diagnosed and relapsed NHL focusing on the common types of NHL with particular reference to the current practice within the local settings. The role of standard and novel therapeutic modalities in treatment will be summarized.

    In the appropriate clinical setting, certain aspects of extranodal abdominal lymphoma, as revealed by current cross-sectional imaging techniques, should be considered potentially diagnostic and can hasten the diagnosis. In addition, diagnostic imaging in the context of biopsy-proven lymphoma can accurately stage the disease for its appropriate treatment. The purpose of this article was to illustrate the various imaging aspects of extranodal lymphoma in the abdomen. (author)

    Primary breast lymphomas, a rare subtype of non-Hodgkin's lymphoma, represent 0.04 to 0.5% of all breast cancers, 0.38 to 0.7% of all lymphomas, and 1.7 to 2.2% of extranodal lymphomas. The treatment choice is based on chemotherapy containing anthracycline and rituximab. Surgery is limited to being less invasive and only for diagnostic purposes. Radiotherapy has an important role as consolidation therapy, particularly in patients with negative nodes. A 70 year old woman with a breast nodule in the left upper outer quadrant, with slow growth, expansive, painless, and accompanied by skin changes, malaise, weight loss, fatigue, chill, and sweating. There was tissue replacement by the mammary gland tumour, skin changes due to invasion, and a 5cm axillary lymphadenopathy. The mammography showed skin thickening and a dense pattern of 80% of breast tissue replacement, and the lymphadenopathy with loss of radiolucent centre and soft tissue invasion. The biopsy confirmed a diffuse high grade large cell lymphoma. She received an Rituximab (R-CHOP) chemotherapy scheme and radiotherapy with tangential and supraclavicular and axillary fields. After completing the chemotherapy, the patient is on follow-up, and at 15 months she is alive without disease activity. Primary lymphoma of the breast is a rare entity. Multimodal treatment with combined chemo-radiotherapy is the cornerstone. Surgery is reserved only for diagnostic purposes. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    This report describes a primary periosteal location of non-Hodgkin's lymphoma, without nodal disease, and without adjacent intramedullary disease at presentation. The clinical and imaging appearance of periosteal lymphoma simulates other neoplastic osseous surface tumors more than that of lymphoma in other locations. Consideration of this rare presentation of non-Hodgkin's lymphoma in the differential diagnosis of periosteal bone lesions can be helpful to ensure proper diagnosis and treatment. (orig.)

    The last 25 years have seen major changes in the imaging investigation and subsequent management of patients with Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL); accurate staging is vital for prognostication and treatment in both, and particularly in HD. The choice of imaging modality for staging depends on its accuracy, impact on clinical decision-making, and availability. Modern CT scanners fulfil most of the desired criteria. The advent of CT scanning, along with the development of ever more effective chemotherapeutic regimens, has resulted in the virtual demise of bipedal lymphangiography (LAG) as a staging tool in patients with lymphoma. It has rendered superfluous a battery of other tests that were in routine use. This contribution reviews the evidence for the use of CT in preference to LAG. CT accurately depicts nodal enlargement above and below the diaphragm, has variable sensitivity for intra-abdominal visceral involvement and is generally outstanding in depicting the extent of disease, especially extranodal extension. Despite the advances in CT technology, there are still areas where CT performs less well (e.g. disease in normal-sized lymph nodes, splenic and bone marrow infiltration). The influence of technical factors, such as the use of intravenous contrast medium, is discussed. In some instances, CT is not the imaging modality of choice and the place of newer techniques such as MRI and endoscopic ultrasound will be reviewed. (orig.)

    Objective: To review the approach to the diagnosis, classification, assessment, treatment and continuing management of patients with non-Hodgkin's lymphoma with an emphasis on the role of radiation therapy and the management of localized disease. Non-Hodgkin's lymphomas are a diverse group of diseases with an age standardized incidence of approximately 17 per 100,000 population. They become more common with increasing age and frequently involve extranodal sites. A number of potential etiological causes have been defined e.g. congenital and acquired immunodeficiency states, viruses, ionizing radiation, chronic inflammatory diseases and environmental toxins. Management is most influenced by the histological type of lymphoma. Numerous classifications have derived from architectural and cytological observations (Rappaport), concepts involving morphologic and phenotypic characterization of lineage and differentiation (Lukes-Collins, Kiel), and grade in the context of cytological differentiation and prognosis (Working Formulation). The introduction of the REAL classification has characterized clinico-pathological entities within a B-cell, T-cell and Hodgkin's disease framework, and recognized histopathologic grade as a variable within each category. The utility of this approach is likely to increase as disease entities become further defined through karyotypic and genotypic characterization. Stage is the other principal determinant of management. Whilst the Ann Arbor staging classification is employed routinely, its limitations in the context of extranodal disease, characterization of local disease extent and bulk have resulted in the incorporation of additional prognostic factors into management policies. Important prognostic factors include patient-related variables (age, performance status), disease-related attributes (bulk, number of involved nodes, B-symptoms) and biological attributes (LDH, ESR, β-2 macroglobulin, soluble CD-30, proliferation indices).

    Full Text Available Introduction. Ecthyma gangrenosum is a rare disease of the skin that causes the localized necrosis of the skin and subcutaneous fat tissue, leading to the multiple ulcerations surrounded by local hyperaemia. The ulcerations are usually localized in groins, and perianal area. In the majority of cases ecthyma is caused by a Pseudomonas aeruginosa sepsis. The disease usually appears in immunocompromized, most frequently hematological patients. Case report. We presented a 78-year-old woman who had been treated for non-Hodgkin lymphoma for the last 18 years. She had recently been given cytotoxics which led to neutropenia. The patient suddenly developed high fever, chill and diarrhea, followed by ecthyma gangrenosum cutaneous lesions in groins, axillas, right side of the neck and umbilicus. Pseudomonas aeruginosa and Proteus mirabilis, that were sensitive to several antibiotics were isolated. The treatment included rehydratation, antibiotics, surgical debridement and regular dressing with antiseptics. The healing of all lesions was achieved after sixteen weeks of the treatment. Conclusion. If haemorrhagic- necrotic lesions of the skin are developed in immunocompromised, usually haematologic patients, an Ecthyma gangrenosum has to be considered immediately, material for identification of a cause has to be taken, followed by immediate administration of antibiotics effective against Pseudomonas aeruginosa. Surgical debridement and other therapeutic modalities are to be considered in some patients. .

    bone marrow autologous transplantation (BMAT) has proven benefits in patients treated for non-Hodgkin's lymphoma (NHL). Plerixafor is an inhibitor of CXCR4 receptor. The aim was to report the raise of hematopoietic cells with plerixafor in patients with NHL. patient 1 with follicular NHL, GI, intermediate FLIPI, CD20+, CD45+, BCL-2+, who reached complete response after three chemotherapy regimes. Mobilization failed after use of filgrastim (G-CSF) alone and G-CSF + cyclophosphamide. A new attempt was made with G-CSF + plerixafor (G-CSF, 10 μg/kg for 7 days + plerixafor, 240 μg/kg in days 4 to 7). Patient 2 with follicular NHL and CD20+ reached complete remission with MINE after therapeutic failure with other regimes, but develops severe marrow toxicity. Mobilization was supported with G-CSF 10 μg/kg/d + plerixafor in days 4 and 5. In case one, proper cell counts where obtained after three aphaeresis. In the second case, two harvests add of 2.7 × 106/kg were obtained. plerixafor raised the hematopoietic stem cells in peripheral blood and improves mobilization of proper cell population.

    Seventeen patients with stage IA non-Hodgkin's lymphoma of the Waldeyer's ring were treated with radiation therapy with or without chemotherapy. All lesions were judged as having intermediate grade malignancy in the Working Formulation. Eight patients received combined treatment with three cycles of cylcophosphamide, doxorubicin, vincristine and prednison (CHOP) and radiation therapy with 30 to 40 Gy. Another 9 patients were treated with radiation therapy 40 to 60 Gy alone. After a median follow-up of 69 months, all 8 patients, treated with combined modality were alive and relapse-free whereas 4 of the 9 treated with irradiation alone had relapsed. All relapses occurred transdiaphragmatically. Two of the 4 relapsing patients were saved, but the other two died of the disease. The 5-year relapse-free and cause-specific survival rates were 100% and 100% in the combined modality group, and 56% and 76% in the radiation therapy alone group (relapse-free: p=0.04, cause-specific: p=0.16). There were no serious complications related to treatment, although most patients complained of mouth dryness and most patients given CHOP had paresthesia. Our opinion was that the total impact of these two side-effects on quality of life was less pronounced after combined modality than after radiation therapy alone. Limited chemotherapy and radiation therapy seemed to be more beneficial than radiation therapy alone not only in relapse-free survival but also in quality of life after treatment. (orig.)

    2007-01-01

    Antibody-based therapeutic approaches have had a significant impact in the treatment of non-Hodgkin's lymphoma (NHL). Rituximab's development as an anti-CD20 antibody heralded a new era in treatment approaches for NHL. While rituximab was first shown to be effective in the treatment of relapsed follicular lymphoma, it is now standard monotherapy for front-line treatment of follicular lymphoma, and is also used in conjunction with chemotherapy for other indolent, intermediate and aggressive B-cell lymphomas. The development of rituximab has led to intense interest in this type of therapeutic approach and to development and approval of the radioimmunoconjugates of rituximab, (90)Y-ibritumomab tiuxetan and (131)I-tositumomab, which have added to the repertoire of treatments for relapsed follicular lymphoma and increased interest in developing other conjugated antibodies. Since rituximab is a chimeric antibody, there is a need to develop fully humanised antibodies, such as IMMU-106 (hA20), in order to minimise infusion reactions and eliminate the development of human antibodies against the drug. Further clinical evaluation of antibodies has been based largely on our knowledge of antigen expression on the surface of lymphoma cells and has led to the development of antibodies against CD22 (unconjugated epratuzumab and calicheamicin conjugated CMC-544 [inotuzumab ozogamicin]), CD80 (galiximab), CD52 (alemtuzumab), CD2 (MEDI-507 [siplizumab]), CD30 (SGN-30 and MDX-060 [iratumumab]), and CD40 (SGN-40). Furthermore, the VEGF (vascular endothelial growth factor) inhibitor bevacizumab, which was first approved for the treatment of colon cancer is currently under investigation in NHL, and agonists rather than antibodies to TRAIL (tumour necrosis factor-related apoptosis-inducing ligand) [rApo2L/TRAIL, HGS-ETR1{mapatumumab}, HGS-ETR2] are currently being investigated as treatments for both advanced solid tumours and NHL.

Os linfomas primários gástricos são comumente LNH, sendo representados em mais de 95% dos casos pelo linfoma difuso de grandes células B e pelo linfoma MALT (mucosa associated lymphoid tissue. De evolução indolente, o linfoma MALT destaca-se por ser um modelo de câncer secundário à estimulação antigênica crônica exercida por uma bactéria denominada Helicobacter pylori (HP. No outro polo, situa-se o linfoma difuso de células B (LDGCB, que, de patogênese duvidosa, pode tratar-se de uma transformação de LNH MALT ou ainda se caracterizar por um linfoma "de novo". Neste estudo, revisamos a literatura, enfatizando aspectos importantes à prática clínica destes linfomas.Extranodal lymphomas account for about 30% of all non-Hodgkin lymphomas (NHL, and although they can originate in any tissue, the gastrointestinal tract is the most commonly affected structure with the stomach being the most common subtype. Diffuse Large B cell lymphoma (DLBCL and MALT (mucosa associated lymphoid tissue lymphoma account for more than 95% of the cases of gastric lymphoma. The indolent development of MALT lymphoma stands out as it is a type of cancer subject to chronic antigen stimulation by the Helicobacter pylori bacteria. Conversely, diffuse large B cell lymphomas, whose pathogenesis is uncertain, can be a transformation from MALT NHL or perhaps a new type of lymphoma. In this study we carried out a review of the literature, stressing the key aspects of these lymphomas in the clinical practice.

    The possibility of using [ 18 F] FDG PET for assessment of tumor extension in primary gastric non-Hodgkin's lymphoma (NHL) was studied in 8 patients (6 high-grade and 2 low-grade, one of the MALT type) and in a control group of 7 patients (5 patients with NHL without clinical signs of gastric involvement, 1 patient with NHL and benign gastric ulcer and 1 patient with adenocarcinoma of the stomach). All patients with gastric NHL and the two with benign gastric ulcer and adenocarcinoma, respectively, underwent endoscopy including multiple biopsies for histopathological diagnosis. All patients with high-grade and one of the two with low-grade NHL and the patient with adenocarcinoma displayed high gastric uptake of [ 18 F] FDG corresponding to the pathological findings at endoscopy and/or CT. No pathological tracer uptake was seen in the patient with low-grade gastric NHL of the MALT type. In 6/8 patients with gastric NHL, [ 18 F] FDG PET demonstrated larger tumor extension in the stomach than was found at endoscopy, and there was high tracer uptake in the stomach in two patients who were evaluated as normal on CT. [ 18 F] FDG PET correctly excluded gastric NHL in the patient with a benign gastric ulcer and in the patients with NHL without clinical signs of gastric involvement. Although the experience is as yet limited, [ 18 F] FDG PET affords a novel possibility for evaluation of gastric NHL and would seem valuable as a complement to endoscopy and CT in selected patients, where the technique can yield additional information decisive for the choice of therapy.

    We present the clinical and magnetic resonance imaging findings of a patient who, following treatment for pancreatic non-Hodgkin's lymphoma (NHL), relapsed with apparently isolated involvement of the right masticator space and left psoas muscles. Non-Hodgkin's lymphoma arising from the masticator space muscles is very rare. In addition, simultaneous lymphomatous involvement of multiple discrete skeletal muscle sites, in the absence of disease elsewhere, has previously only been reported in the limb or limb girdle muscles. Lymphoma should be considered as a cause of isolated enlarged skeletal muscles, even when involving such distant sites. (orig.)

    We report the case of a left laparoscopic nephroureterectomy with the incidental discovery of a non-Hodgkin's lymphoma in one of the lymph nodes of the renal hilum. A laparoscopic nephroureterectomy was decided on for a 64-year-old man. Renal cell carcinoma in the kidney and one lymph node of the renal hilum with non-Hodgkin's lymphoma was found. Chemotherapy was not started for the lymphoma discovery. There are no signs of relapse after two years of follow up. Coexistence in the same patient is an extremely rare condition. We review the literature about this issue to clarify this association.

    Full Text Available Abstract Introduction Primary non-Hodgkin's lymphoma of the small and large bowel presenting as a perforated viscus entity with peritonitis is extremely rare. A thorough literature review did not reveal any cases where primary lymphoma of the jejunum presented with perforation and peritonitis synchronously with primary lymphoma of the descending colon. Case presentation This report concerns a 64-year-old Caucasian woman admitted with severe abdominal pain and fever. An emergency laparotomy revealed a large mass with perforation in the proximal jejunum with intense mesenteric thickening and lymphadenopathy. The descending colon was edematous and covered with fibrinous exudate. Histopathological examination of the resected segment of jejunum revealed a T cell non-Hodgkin's lymphoma. On post-operative day 10, a computed tomography scan of our patient's abdomen and pelvis showed leakage of contrast into the pelvis. Re-exploration revealed perforation of the descending colon. The histopathology of the resected colon also showed T cell non-Hodgkin's lymphoma. Her post-operative course was complicated by acute renal and respiratory failure. The patient died on post-operative day 21. Conclusions Lymphoma of the small intestine has been reported to have a poor prognosis. The synchronous occurrence of lesions in the small intestine or colon is unusual, and impacts the prognosis adversely. Early diagnosis and treatment are important to improve the prognosis of bowel perforation in patients with non-Hodgkin's lymphoma.

    Malignant non-Hodgkin lymphomas are a neoplastic proliferation of lymphoid cells whose clinical manifestations are extremely variable. All tissues can be affected. There may be localization in lymphoid organs (Waldeyer's ring, spleen, digestive tract), other localizations (lungs, pleura, liver, bone marrow, central nervous system) and unusual localizations. Although bone marrow is often affected, bone involvement is very rare in the early stages of the disease. This report concerns the radiological study of two disseminated malignant non-Hodgkin lymphomas affecting only the bone in children. (orig.)

    67 Ga imaging of non-Hodgkin's lymphoma is useful for evaluating the presence of viable tumour in a residual mass after treatment. However, we have frequently seen gallium uptake in the pulmonary hila without other evidence of lymphoma. To study the significance of this finding, 79 patients with intermediate grade non-Hodgkin's lymphoma were reviewed. Thirty-seven (47%) had abnormal hilar gallium uptake. Twenty-three of these could be fully evaluated, and only five (22%) had hilar lymphoma. A pattern of bilateral, symmetric hilar uptake was seen in 19 patients, but only one had evidence of lymphoma. In 15 cases, this pattern was seen only on single photon emission computed tomography (SPECT). The aetiology of this uptake remains unknown. It is not treatment related, as 12 patients had hilar gallium uptake prior to chemotherapy. Unless confirmed by other methods, hilar gallium uptake should not be attributed to lymphoma, and should not influence patient management. (Author)

    2016-09-01

    Full Text Available Mature natural killer /T-cell (NK/T-cell lymphomas are a rarely occurring subgroup of Non Hodgkin Lymphomas (NHL. A large majority of NK/T cell lymphomas are extranodal. Nasal type is the most common one. As clinical symptoms are usually nasal obstruction associated with mass lesion and epistaxis in extranodal NK/T cell lymphomas. Their diagnosis is usually delayed when the disease is advanced, it may have serious consequences. The aim of the present article was to present the clinical, radiological and histopathological findings of a 69-year old female patient who had refractory ulcerated wound on left side of nose and followed for soft tissue infection. It was diagnosed with extranodal NK/T cell lymphoma after deep biopsy was obtained from the lesion and to discuss this rare disease in view of literature data.

    Full text: Chernobyl liquidators were workers involved in the clean-up of contaminated areas around the Chernobyl power plant following the accident on 26 April 1986. These workers form a potentially important population for evaluation of the effects of protracted low doses of ionizing radiation. A collaborative case-control study of leukaemia and non-Hodgkin lymphoma (NHL) was set-up, nested within cohorts of Belarus, Russian and Baltic countries liquidators. The objective was to evaluate the radiation-induced risk of these diseases in this population and to study the effect of exposure protraction and radiation type on the risk of radiogenic cancer in the low to medium (0-500 mSv) radiation dose range. The study population consisted of approximately 66,000 Belarus, 65,000 Russian and 15,000 Baltic countries liquidators who took part in the clean-up activities between 26 April 1986 and 31 December 1987. In Belarus and Russia, liquidators are followed through the Chernobyl Registries and must undergo regular health check-ups, while in the Baltic countries their migration, vital and cancer status are assessed through population, death and cancer registries. The case ascertainment period ranged from 1990 to 2000 with minor differences among the countries. Information on study subjects was obtained through a face-to-face interview with the study subject and/or a proxy (a relative or a colleague), using a standardized questionnaire on demographic factors, time, place and conditions of work as a liquidator and on potential risk and confounding factors for leukaemia. A method of analytical dose reconstruction, entitled RADRUE (Realistic Analytical Dose Reconstruction with Uncertainty Estimation), was developed within the study, validated and applied to estimate individual dose to the bone marrow and related uncertainties for each subject. 117 cases (69 leukaemia, 34 NHL and 14 other malignancies of lymphoid and haematopoietic tissue) and 481 matched controls were

    Full Text Available Context: Incidence of non-Hodgkin's lymphoma (NHL is increasing in all parts of the world, especially over the past few decades. An insight into the clinical presentation may help in the prevention, control, and treatment of NHL. Aim: To observe the clinicopathological patterns of NHL among patients in Northeast India. Subjects and Methods: A retrospective case study on 100 proven cases of NHL registered at the Regional Institute of Medical Sciences, Manipur, during the period January 2013–May 2017 was conducted, and data were reviewed and analyzed. Statistical Analysis Used: Data were analyzed using SPSS-21 and results were presented in percentages and simple frequency. Results: Majority (43.0% of the patients were in the age group of 41 and 60 years. The mean age was 54.01 ± 18.1 years. Male:female ratio was 1.2:1. The most common presenting symptom was neck swelling (57.0%, and peripheral lymphadenopathy (76.0% was the most common sign. Primary site distribution was nodal (57.0% and extra-nodal NHL (43.0%. Most common nodal site involved was cervical lymph nodes (65.0%, and gastrointestinal tract (17.0% was the most common extranodal subsite. Majority of the patients were in stage II (36.0% at the time of diagnosis. B-cell NHL accounts for 66.0% compared to T-cell lymphoma (23.0%. Diffuse large B-cell lymphoma was the most frequent B-cell lymphoma (45.0%, and anaplastic large cell lymphoma was the most common T-cell variant (15.0%. Conclusions: A thorough insight into the clinical spectrum of NHL is necessary for optimum management and improved treatment outcome.

  14. Non-Hodgkin's lymphoma presenting as a primary bladder tumor: a case report

    2010-04-01

    Full Text Available Abstract Introduction Primary lymphoma of the bladder represents 0.2% of all bladder malignancies. Secondary involvement of the bladder by malignant lymphoma occurs in 10% to 50% of cases. Most lymphomas of the bladder are non-Hodgkin's lymphomas of the B-cell type, with preponderance among women. The impact of positron emission tomography (PET on tumor staging has recently become very important due to its use in the study of diagnosis extension and individual therapy design. Case presentation We report the case of a 79-year-old Caucasian man with intermittent haematuria as the presenting symptom of non-Hodgkin's lymphoma of the bladder. He was first diagnosed with primary lymphoma of the bladder using the current staging method, but a positron emission tomography study subsequently revealed that he instead had a secondary involvement of the bladder. Conclusion The staging of non-Hodgkin's lymphomas, which is useful in order to plan accurate therapy, has been changing since the introduction of positron emission tomography scanning. Primary lymphomas of the bladder, although very rare, may be even more uncommon when this imaging technique is used to assess the extension of the disease. Although the interpretation of this technique has some limitations that should be taken into account, the extensive use of positron emission tomography should nonetheless help improve the diagnosis of this disease.

    Objective: To analyze the clinical characteristics, treatment and prognosis of primary parotid non-Hodgkin's lymphoma. Methods: From March 1988 to February 2001, twenty-nine patients with primary parotid non-Hodgkin's lymphoma treated in our hospital were retrospectively analyzed. The data were analyzed according to the following factors: sex, age, stage, pathologic classification, chemotherapy given or not, cycles of chemotherapy, radiotherapy given or not, and the dose at the parotid. Kaplan-Meier method and Log-rank method were used in the statistic analysis. Results: The overall 5-year and 10-year survival rates were 73.3% and 51.0%. Stage and pathologic classification were prognostic factors in our statistic analysis. The 5-year survival rates were 81.6% and 25.0% for early stage (I E + II E) and advanced stage (III E + IV E) patients, with the difference significant (P<0.01). The 5-year survival rate for patients with the pathologic classification of mucosa associated lymphoid tissue (MALT) was 100% as compared to 42.2% for patients with diffused large B cell lymphoma, with the difference also significant (P<0.05). Conclusions: The prognosis of primary parotid non-Hodgkin's lymphoma is satisfactory. Surgery should only be used as a diagnostic method. Radiotherapy should be the first choice for patients with MALT lymphoma and stage I E and II E follicular lymphoma, but comprehensive treatment including chemotherapy is necessary to the diffuse large B cell lymphoma

    261 case historys of malignant non-Hodgkin-lymphomas were analysed in the years from 1969 until 1978 in the 'Radiologische Universitaetsklinik Kiel'/West-Germany. 18 Patients got a central nervous complication of Non Hodgkin-Lymphoma earlier or later, a percentage of about 7. There were 7 cases of lymphoblastic lymphoma (LB), a percentage of 10 for this entity. In the group of immunoblastic lymphoma (IB) 6 cases of central nervous infiltration were detected, that is a ratio of 7.7 percent. 4 case histories M. Brill-Symmers (CC/CB) were complicated by central nervous dissemination, a percentage of 5.3. Patients with lymphoblastic lymphoma have the highest risk of central nervous complication. The beginning of central nervous dissemination in the single case histories is very different between the histological groups. Patients with lymphoblastic lymphoma suffered from central nervous complication in an early phase of history, in cases of M. Brill-Symmers central nervous infiltration can occur also in a late phase. The results may determine the discussion about stratifying of radiotherapy. Early radiotherapy including central nervous system may be discussed and investigated in special histological entities of malignant non-Hodgkin-lymphoma. (orig.) [de

    Primary nonHodgkin's lymphoma of the testis is a localized disease in 50 per cent of the cases. Clinical records and pathological material from 9 stage IE cancer patients treated at our institutions were reviewed. All but 1 patient had B cell type lymphomas of intermediate (6) or high (3) grade according to the Working Formulation. Mean survival was 49 months and actuarial survival was 74 per cent at 5 years. Chemotherapy differed with time and frequently was associated with subdiaphragmatic involved field and prophylactic contralateral testis radiotherapy. In view of the good prognosis of patients receiving doxorubicin-based chemotherapy and recent reports on low stage nonHodgkin's lymphoma we recommend an aggressive brief therapy for stage IE lymphoma of the testis after orchiectomy

    International Nuclear Information System (INIS)

    Montravers, F.; Kerrou, K.; Gutman, F.; Grahek, D.; Talbot, J.N.

    2006-01-01

    As for adult population, FDG PET is recognized as an efficient tool for staging, adaptation of therapy and follow-up of Hodgkin's disease in children. The interpretation of PET needs however to take into account some specificities of imaging as the frequent brown fat activation and the physiologic thymic uptake. The role of FDG PET in non Hodgkin's lymphoma (NHL) in children is less established. Although LNH are more frequent than Hodgkin 's lymphoma in children, FDG PET is rarely performed at diagnosis, probably due to the therapeutic emergency of these aggressive pediatric forms. During follow-up, FDG PET has been however shown to be useful, especially for the characterization of residual masses. (authors)

    Our study aims to compare diagnostic accuracy between 18 F-FDG PET and 67 Ga SPECT in the staging of non-Hodgkin's lymphoma. Twenty-eight patients with non-Hodgkin's lymphoma, underwent 18 F-FDG PET, 67 Ga SPECT and CT for the pretreatment staging of malignant lymphoma between August 1999 and March 2002. 18 F-FDG PET imaging was obtained 60 minutes after the intravenous administration of 185 MBq of 18 F-FDG. 67 Ga SPECT imaging was obtained 2 days after the intravenous administration of 148 MBq of 67 Ga. 18 F-FDG PET and 67 Ga SPECT were performed within one month. Both imagings were performed on the area from the neck to the pelvis. The 18 F-FDG PET and 67 Ga SPECT findings were compared with the CT findings and the clinical course. Sixty-six nodal lesions were clinically confirmed. Of these, 32 were identified by both 18 F-FDG PET and 67 Ga SPECT. The remaining 34 lesions were identified only by 18 F-FDG PET. The mean (±SD) sizes of the nodes were 34.7±32.4 mm for 18 F-FDG-positive and 67 Ga-positive lesions and 15.7±8.3 mm for 18 F-FDG-positive and 67 Ga-negative lesions (p 18 F-FDG PET and 67 Ga SPECT, whereas 6 lesions were identified by only 18 F-FDG PET. Five lesions were not identified by either technique. No 18 F-FDG-negative but 67 Ga-positive nodal or extranodal lesions were observed. The difference in findings between the two studies is related to the difference in the size but not in the histology or site of the lesions. 18 F-FDG PET detected significantly more lesions particularly small lesions than 67 Ga SPECT. Thus, 18 F-FDG PET is considered to be superior to 67 Ga SPECT in the staging of non-Hodgkin's lymphoma. (author)

    2012-01-01

    Full Text Available Primary bilateral non-Hodgkin's lymphoma (NHL of the adrenal gland is a very rare entity. Indeed less than 60 cases have been reported in the literature. Hence, we report a case of high-grade lymphoma of both adrenal glands that was found in a young patient of 32 years of age. The patient was admitted in the emergency department of our hospital with a profile of hemorrhagic shock. After stabilization, the imaging investigations demonstrated large bilateral adrenal masses. The CT-scan guided biopsy of both adrenal glands allowed the diagnosis of primary bilateral adrenal NHL. The patient died after the first chemotherapy session. The presence of bilateral adrenal masses associated with a rapid increase of volume should raise the diagnosis of primary adrenal non-Hodgkin's lymphoma.

    Thirty-four patients with Hodgkin's disease and non-Hodgkin's lymphoma underwent therapeutic splenectomies to improve hematologic tolerance for chemotherapy. The mean age was 40 years; there were 16 males and 18 females. Fourteen had Hodgkin's disease, 19 had non-Hodgkin's lymphoma, and 1 had malignant histocytosis. Nineteen had palpable splenomegaly, 19 had marrow involvement and 20 had splenic involvement by lymphoma. The following data were analyzed before and after splenectomy: mean white blood cell count (WBC) and platelet count on planned first day of cycle, delay ratio of chemotherapy delivery and percent maximal dose rate. Thirteen patients had non-Hodgkin's lymphoma, splenomegaly and positive bone marrow and showed significant benefit in all of the aforementioned parameters. Of the patients with prior irradiation, only those who completed their radiation greater than six months prior to splenectomy showed benefit. Ten patients had Hodgkin's disease, negative bone marrow and no splenomegaly. This group showed significant improvement in mean platelet count but more limited benefit in delay ratio and percent maximal dose rate. Thus, selected patients with lymphoma who are experiencing delays in chemotherapy because of poor count tolerance may benefit from splenectomy

    The purpose of this study was to examine, retrospectively, national-wide clinical data of patients with localized extranodal non-Hodgkin's lymphoma (NHL) who were treated by radiation therapy with or without chemotherapy. The survey was carried out at 25 radiation oncology institutions in Japan in 1998. In 1999, according to the Revised European American Lymphoma (REAL) classification, central pathological review conducted at Aichi cancer center was carried out for the data from 7 radiation oncology institutions. The 5-year progression free survival rates (PFS) were calculated to identify prognostic factors. Survey: Data from 1, 141 patients with stage I and II NHL were recruited from 1988 through 1992. Of them, 787 patients, who were treated using definitive radiotherapy with or without chemotherapy for intermediate and high-grade lymphomas in Working Formulation, constituted the core of this study. Primary tumors arose mainly from extra-nodal organs (71%) in the head and neck (Waldeyer's ring: 41%, thyroid gland: 7%, nasal cavities: 5%, oral cavities: 4%, sinus: 3%, orbital structures: 3%, skin: 2% and etc.). The median age of 60 years for patients with extra-nodal NHL was higher than that of 56 years for patients with nodal NHL (p<0.01). Female were dominant in incidence of extra-nodal NHL arising from the thyroid gland, skin and gastrointestinal tract. The percentage of stage I to the extra-nodal NHL from orbit, sino-nasal presentation was higher than that of other NHLs. The percentage of stage II to the extra-nodal NHL from Waldeyer's ring and thyroid gland was higher than that of other NHLs. Central pathological review was carried out for pathological data from 79 patients (Waldeyer's ring: 45, thyroid gland: 19, sinonasal cavities: 15). Of these, diffuse large B cell lymphoma (DLBCL) composed 63% of all patients, mucosa associated lyumphoid tissue lymphoma (MALT-L): 16%, Natural Killer/T cell lymphoma (NK/T-L): 11%, and mantle cell lymphoma: 5% in REAL

    Full Text Available BackgroundPrimary extranodal marginal zone lymphoma (MZL of the dura is a rare neoplastic entity in the central nervous system (CNS.MethodsWe used literature searches to identify previously reported cases of primary dural MZL. We also reviewed clinical, pathologic, and radiographic data of an adult patient with concurrent dural MZL and chronic lymphocytic leukemia (CLL/small lymphocytic lymphoma (SLL.ResultsWe identified 104 cases of dural MZL in the literature. None of them presented concurrently with another type of non-Hodgkin lymphoma. This is the first report of composite lymphoma consisting of dural MZL and CLL/SLL in the bone marrow and lymph nodes.ConclusionPrimary dural MZL is a rare, indolent low-grade CNS lymphoma, with a relatively good prognosis. Its treatment is multidisciplinary and often requires surgical intervention due to brain compression, along with low to moderate doses of radiotherapy and/or systemic chemotherapy.

    2012-02-01

    We describe the case of a 57-year-old man who was referred to us with persistent sore throat, dysphagia, and enlarged tonsils. He had not responded to earlier treatment with antibiotic therapy and other routine measures. In view of the persistent nature of the patient\\'s symptoms and the tonsillar hypertrophy, we decided to perform a tonsillectomy and to send the excised specimens for pathologic analysis. Histologic evaluation identified non-Hodgkin lymphoma in both tonsils. The patient was treated with postoperative chemo- and radiotherapy, and he was free of symptoms during 18 months of follow-up. To the best of our knowledge, only 4 cases of bilateral non-Hodgkin lymphoma of the tonsils have been reported in the English-language literature. We also discuss the importance of histologic analysis of excised tonsil tissue in selected cases.

    One hundred and eighteen patients with nodular non-Hodgkin's lymphoma were randomized to receive either chemotherapy alone or chemotherapy plus radiotherapy (total nodal or involved field irradiation). Although the complete remission rate was similar in the three programs (about 90%) the relapse-free survival rate (RFS) among patients with complete remission was significantly higher in the groups treated with chemotherapy plus radiotherapy than among those treated with chemotherapy alone. The 7-year RFS in the groups treated with total node irradiation and involved field irradiation was 71% and 66% respectively, compared to only 33% in the group treated by chemotherapy alone (p<0.01). The results suggest that combined chemoradiotherapy may achieve complete long-term remission and potential cure in more than 60% of patients with nodular low-grade non-Hodgkin's lymphoma. Toxicity was moderate in all three arms. Bulky disease and a high level of lactic dehydrogenase were associated with a poor prognosis. (orig.)

    Full Text Available Intestinal intussusception rarely occurs in the adult population and accounts only for 1% to 5% of all the causes of intestinal obstruction. This complication is more frequent in the small bowel and can be due to different aetiologies, including inflammatory, infectious or neoplastic diseases. Malignancies account for 50% to 60% of all cases of colon invagination. The gastrointestinal (GI tract is the most common site for extra-nodal non-Hodgkin lymphomas (NHL, representing 5% to 20% of all the cases. However, primary NHL of the GI tract is a very infrequent clinic-pathological entity and accounts only for 1% to 4% of all the neoplasms of the GI tract. Primary NHL of the colon is a rare disease and it comprises only 0.2% to 1.2% of all colonic malignancies. Here we describe a case of an AIDS adult patient who developed an intussusception secondary to a primary large B cell lymphoma of the transverse colon. English and Spanish literature was reviewed.

    2009-09-01

    Full Text Available Primary non-Hodgkin’s lymphomas (NHL of the sinonasal tract are rather uncommon entities. Morphologically and radiographically, sinonasal lymphomas are difficult to distinguish from other malignant neoplasms or non- neoplastic processes. They have a variable presentation from fulminant destructive manifestations to chronic indolent type of disease and may mimic as carcinomas and invasive fungal infection respectively. We report a case of primary NHL involving sinonasal tract in elderly female, which was clinically and radiologically mimicking as sinonasal malignany and was proven as NHL on histological examination and confirmed by immunohistochemistry. A high index of suspicion, appropriate histopathological examination and immunohistochemistry is necessary to differentiate sinonasal lymphomas from other possibilities. Failure to do so may miss the diagnosis and delay appropriate treatment

    Full Text Available The treatment of patients with non- Hodgkin’s lymphoma (NHL is often the treatment of elderly patients, as most patients are older than 65 years at diagnosis. These elderly patients present particular therapeutic challenges, because they may be more frail and at greater risk of treatment-related toxicity, especially anthracycline-related cardiotoxicity, than younger patients. The following two case studies illustrate the challenges and therapeutic decision-making in managing elderly patients with an aggressive and an indolent form of lymphoma.

    OBJECTIVE: Nasopharyngeal (NP) non-Hodgkin's lymphoma (NHL) is an uncommon tumour. The aim of the study was to describe the appearances on CT and MR imaging, and identify the features which help to distinguish NPNHL from other NP tumours. MATERIALS AND METHODS: The CT (n=8) and MR (n=10) images of 14 patients with NPNHL were reviewed retrospectively. Patients with NPNHL were divided into primary NPNHL, where the primary tumour was in the NP (n=7) and secondary NPNHL where the primary tumour was at another extranodal site in the head and neck (n=7). All NPNHL were assessed for tumour size and distribution, appearance and local tumour invasion, in addition lymphadenopathy was assessed in primary NPNHL. RESULTS: The NPNHL ranged in size from 20-75 mm (mean of 55 mm for primary and 30 mm for secondary NHL) and were homogeneous on CT in eight (100%) and MR in seven (70%) and mildly heterogeneous on MR in three (30%) patients. NPNHL involved all walls of the NP in 10 (71%) and extended in an exophytic fashion to fill the NP cavity in six (43%). Deep tumour invasion was present in two (14%) both patients with primary NHL, the extent and volume of this tumour invasion was small and involved the prevertebral muscles (n=2), parapharyngeal fat space (n=1) and skull base (n=1). Primary NPNHL extended superficially in five (71%) to involve the nasal cavity (n=3) and oropharynx (n=2) and lymphadenopathy was present in five (71%) being bilateral and involving multiple nodal sites (n=4) with necrosis (n=2) and matting (n=3). CONCLUSION: NPNHL is a homogeneous tumour that tends to diffusely involve all walls of the nasopharynx and spread in an exophytic fashion to fill the airway, rather than infiltrating into the deep tissues. Deep tumour infiltration, when it occurs, is found in those patients with primary NHL and is usually limited in extent and of small volume. Primary NHL more commonly spreads superficially to involve the nasal cavity or oropharynx, lymphadenopathy is frequent

    Full Text Available Abstract Background Solitary involvement of the sphenoid sinus has rarely been reported in non-Hodgkin's lymphoma. Isolated oculomotor nerve palsy is uncommon as an initial presentation of malignant tumors of the sphenoid sinus. Case presentation A 53-year-old woman presented with a three-month history of headache and diplopia. Neurological examination revealed complete left oculomotor nerve palsy. Magnetic Resonance Imaging (MRI demonstrated a homogenous soft-tissue lesion occupying the left sphenoid sinus and invading the left cavernous sinus. The patient underwent transsphenoidal biopsy and the lesion was histologically diagnosed as non-Hodgkin's lymphoma, diffuse large B-cell type. Tumor cells were positive for CD20 and negative for CD3. Following six cycles of chemotherapy, the left oculomotor nerve palsy that had been previously observed was completely resolved. There was no enhancing lesion noted on follow-up MRI. Conclusion It is important to recognize that non-Hodgkin's lymphoma of the sphenoid sinus can present with isolated oculomotor nerve palsy, although it is extremely rare. The cranial nerve deficits can resolve dramatically after chemotherapy.

    To describe the success rate and the complications after procedures to diagnose abdominal non-Hodgkin's lymphoma in children and adolescents. A retrospective cross-sectional study was conducted with a population consisting of children and adolescents with abdominal non-Hodgkin's lymphoma diagnosed between September 1994 and December 2012. The sample comprised of 100 patients who underwent 113 diagnostic procedures, including urgent surgery (n=21), elective surgery (n=36), and non-surgical diagnosis (n=56). The most frequent procedures were laparotomy (46.9%) and ultrasound-guided core biopsy (25.6%). The rate of diagnostic success was 95.2% for urgent surgeries; 100% for elective surgeries and 82.1% for non-surgical procedures (p<0.05). The rates of complication during the three diagnosis procedures considered were significant (p<0.001; 95.2% of the urgent surgeries, 83.8% of the elective surgeries, and 10.7% of the non-surgical procedures). The length of time before resuming a full diet and starting chemotherapy was significantly reduced for patients who underwent non-surgical procedures when compared with the other procedures (p<0.001). Non-surgical procedures for the diagnosis of pediatric abdominal non-Hodgkin's lymphoma are an effective option with low morbidity rate, allowing an earlier resumption of a full diet and chemotherapy initiation. Furthermore, non-surgical procedures should also be considered for obtaining tumor samples from patients with extensive disease. Copyright © 2017. Published by Elsevier Editora Ltda.

    Full Text Available Background. Although the patients with diagnosed B-NHL are classified into the same disease stage on the basis of clinical, histopathological, and immunological parameters, they respond significantly different to the applied treatment. This points out the possibility that within the same group of lymphoma there are different diseases at molecular level. For that reason many studies deal with the detection of gene alterations in lymphomas to provide a better framework for diagnosis and treatment of these hematological malignancies. Aim. To define genetic alterations in the B-NHL with highest possibilities for diagnostic purposes and molecular detection of MRD. Methods. Formalin fixed and paraffin embedded lymph node tissues from 45 patients were examined by different PCR techniques for the presence of IgH and TCR γ gene rearrangement; K-ras and H-ras mutations; c-myc amplification and bcl-2 translocation. There were 34 cases of B-cell non-Hodgkin’s lymphoma (B-NHL, 5 cases of T-cell non-Hodgkin’s lymphoma (T-NHL and 6 cases of chronic lymphadenitis (CL. The mononuclear cell fraction of the peripheral blood of 12 patients with B-NHL was analyzed for the presence of monoclonality at the time of diagnosis and in 3 to 6 months time intervals after an autologous bone marrow transplantation (BMT. Results. The monoclonality of B-lymphocytes, as evidenced by DNA fragment length homogeneity, was detected in 88 % (30/34 of B-NHL, but never in CL, T-NHL, or in normal PBL. Bcl-2 translocation was detected in 7/31 (22.6% B-NHL specimens, c-myc amplification 9/31 (29%, all were more than doubled, K-ras mutations in 1/31 (3.23% and H-ras mutations in 2/31 (6.45% of the examined B-NHL samples. In the case of LC and normal PBL, however, these gene alterations were not detected. All the patients (12 with B-NHL had dominant clone of B-lymphocyte in the peripheral blood at the time of diagnosis while only in 2 of 12 patients MRD was detected 3 or 6 months after

    2017-03-01

    Full Text Available We, here, report a case of primary breast lymphoma in a 59 years old female. The diagnosis was suspected on fine needle aspiration cytology and confirmed on excision biopsy of the tumor. Histology and immunophenotyping were in accordance with non-Hodgkin's diffuse large B-cell lymphoma. The patient has been planned for adjuvant chemoradiation. The management and outcome of primary breast lymphoma and carcinoma are totally different. Early and prompt diagnosis of primary breast lymphoma is of utmost importance to avoid unnecessary mastectomies. Fine needle aspiration cytology supplemented by immuno-cytochemistry can be applied as a reliable and cost-effective tool in the early diagnosis of primary breast lymphomas, while histopathology and immunohistochemistry are conclusive.

    lymphoma (HL), RT to residual disease and/or initial bulk benefits some patients, depending on the chemotherapy regimen used. The more intensive the chemotherapy regimen, the fewer patients benefit from RT. In advanced aggressive non-Hodgkin lymphoma (NHL), most of the evidence comes from the most common...... type, the diffuse large B cell lymphoma (DLBCL). In patients treated with modern immunochemotherapy, RT to initial bulky disease or extralymphatic involvement is beneficial. For both HL and aggressive NHL, RT to residual masses after systemic treatment is of benefit. The role of PET in the evaluation......Radiation therapy (RT) is one of the most effective agents available in the treatment of lymphomas. However, it is a local treatment, and today, with systemic treatments assuming a primary role for induction of response, RT is primarily used for consolidation. For advanced stage lymphomas...

METHODS AND RESULTS: We have analysed sequential biopsies from 42 non-Hodgkin's lymphoma patients immunohistochemically for p53 alterations (based on p53 and p21Waf1 expression), as well as for expression of MDM2, p27Kip1 and cyclin D3. Relapse of follicle centre lymphoma was associated with p53...... alterations as 5/6 (83%) follicle centre lymphomas with normal p53 at diagnosis showed p53 alterations at relapse. Of these cases, three showed transformation to diffuse large B-cell lymphoma. p53 alteration was also associated with relapse of de novo diffuse large B-cell lymphoma and T-cell non......-Hodgkin's lymphoma, as 2/5 (40%) diffuse large B-cell lymphomas and 3/9 (33%) T-cell non-Hodgkin's lymphomas with normal p53 at diagnosis showed p53 alterations at relapse. No indolent non-Hodgkin's lymphoma case showed MDM2 over-expression at diagnosis, whereas 4/5 (80%) transformed diffuse large B-cell lymphomas...

    Full Text Available Abstract A family is reported in which three male siblings of Asian descent developed non-Hodgkin's lymphoma (NHL. Case 1 was diagnosed with indolent follicular lymphoma stage IIIA at age 45. Case 2 presented with large B-cell lymphoma stage IIB at age 56. Chromosomal investigation of the peripheral blood did not show abnormalities. Chemotherapy induced a complete remission. However, after a period of nearly ten years he developed acute myeloid leukaemia. Case 3 developed large B-cell lymphoma stage IVA at age 52. Cytogenetic analysis in peripheral blood was normal. Shared genetic and environmental risk factors remain to be identified in this family. Familial aggregation of NHL is uncommon. In some families, various forms of immunodeficiency have been found. In addition to coincidental clustering of cases, and rare cases explained by known tumour syndromes such as Li-Fraumeni (like syndrome, other familial cases may share as yet unknown genetic and/or environmental risk factors.

    Purpose: To identify the prognostic factors that specifically predict survival rates of patients with localized aggressive non-Hodgkin's lymphoma (NHL). Methods and Materials: The survey was carried out at 25 radiation oncology institutions in Japan in 1998. The 5-year event-free (EFS) and overall survival rates (OAS) were calculated, and univariate and multivariate analyses were done to identify which of the following factors, namely, gender, age, performance status (PS), serum lactate dehydrogenase (LDH) level, Stage (I vs. II), tumor bulk (maximum diameter), and treatment, were significant from the viewpoint of prognosis. Results: A total of 1141 patients with Stage I and II NHL were treated by the Japanese Lymphoma Radiation Therapy Group between 1988 and 1992. Of them, 787 patients, who were treated using definitive radiotherapy with or without chemotherapy for intermediate- and high-grade lymphomas in working formulation, constituted the core of this study. Primary tumors arose mainly from extranodal organs (71%) in the head and neck (Waldeyer's ring: 36% and sinonasal cavities: 9%). The factors associated with poorer prognosis were age over 60 years old (p < 0.0001), radiation therapy alone (p < 0.0001), PS = 2-4 (p = 0.0011), (sex male, p = 0.0078), a bulky tumor more than 6 cm in maximum diameter (p 0.0088), elevated LDH (p = 0.0117), and stage II (p = 0.0642). A median dose of 42 Gy was delivered mainly to the involved fields. Short-course chemotherapy was provided in 549 (70%) patients. The 5-year OAS and EFS rates for all patients were 71% and 67%, respectively. According to the stage-modified International Prognostic Index, the 5-year EFS of the patients with risk factors from 0 to 1 was 76%, 61% for patients with two risk factors, and 26% for patients with three or more risk factors. Conclusion: Extranodal presentation, especially Waldeyer's ring and sinonasal cavities, is encountered more frequently in Japan than in Western countries. Tumor bulk is

    Full Text Available Calcitriol-mediated hypercalcemia is a frequent manifestation of hematological malignancies. However, there are a few reports of cases presenting with increased angiotensin-converting enzyme (ACE level, which suggests a possible mechanism similar to that of granulomatous diseases. We present a patient with hypercalcemia, normal parathyroid hormone, and parathyroid hormone-related protein levels but high calcitriol and ACE levels that, after further investigation, was diagnosed with bilateral adrenal non-Hodgkin's B-cell lymphoma. Primary adrenal lymphoma represents only 1% of all non-Hodgkin's lymphomas and is usually asymptomatic but should be considered by clinicians among the malignancies that cause calcitriol-mediated hypercalcemia.

    A differentiated clinical and pathoanatomical classification of non-Hodgkin lymphomas is presented. On this basis, diagnostic, prognostic and pathophysiological information on the main types of lymphoma can be obtained from the measurement of the rosette-forming cell fraction (T-cell fraction) and from the autoradiographic determination of the proliferating cell fraction. This approach under the aspect of proliferation kinetics was employed in 9 patients with chronic B-lymphadenosis, 3 patients with chronic T-lymphadenosis, 14 patients with immunocytoma, 15 patients with different types of non-Hodgkin lymphoma, and 3 patients with angioimmunoblastic lymphadenopathy, both for primary diagnosis and in follow-up examinations.

    Full Text Available We present a woman referred with underlying non-Hodgkin's lymphoma (NHL masquerading clinically with Guillain-Barré syndrome (GBS like syndrome. At first evaluation, chest CT-Scan along with brain and whole spine MRI were normal. Electrodiagnostic studies were in favor of acute generalized polyradiculoneuropathy. Laboratory evaluation revealed hypoglycorrhachia. She treated with plasmapheresis after two weeks; she was discharged from hospital, but neurological recovery was not complete. After 6 months, she came back with acute onset of weakness in lower limbs, back pain, fever and urinary incontinence. Pinprick and light touch complete sensory loss was found beneath umbilicus. Thoracic MRI with contrast revealed a dorsal epidural mass extending smoothly from T8 to T12 (10 cm with spinal cord compression. She underwent urgent laminectomy for spinal cord decompression. Histological examination revealed small round cell tumor suggestive of malignant T-cell type lymphoma. In cases with Guillain-Barré syndrome presentation, systemic hematologic disorders such as non-Hodgkin's lymphoma should be considered as one of the differential diagnosis of underlying disease.

    Full Text Available Hepatobiliary involvement by malignant lymphoma is usually a secondary manifestation of systemic disease, whereas primary non-Hodgkin's lymphoma of the extrahepatic biliary ducts is an extremely rare entity. We describe the case of a 57-year-old man who presented with an acute onset of obstructive jaundice and severe itching. Abdominal ultrasonography and computed tomography revealed intrahepatic and common hepatic ducts dilatation. Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography showed a mid-common bile duct stricture. The patient was presumed to have cholangiocarcinoma of the common bile duct, and an en bloc resection of the tumor with Roux-en-Y hepaticojejunostomy and porta-hepatis lymph nodes dissection was performed. Histopathology and immunohistochemistry revealed a large B cell non-Hodgkin's lymphoma. The patient received six cycles of combination chemotherapy using cyclophosphamide, vincristine, prednisone, and rituximab (CVP-R protocol, and after a 5-year follow-up he is still in complete remission. We also reviewed the cases published from 1982 to 2012, highlighting the challenges in reaching a correct preoperative diagnosis and the treatment modalities used in each case.

    In order to evaluate the possible role of MRI in detecting lymphomatous marrow involvement, a MRI examination was performed in newly diagnosed patients with Hodgkin's disease (HD) and nonHodgkin lymphoma (NHL). From this the authors concluded that MRI should not be used as a replacement for bone marrow biopsies in HD and NHL, but rather as a complementary tool utilizing the panoramic view offered by MRI which permit to disclose focal areas of bone involvement different from the sacrum, thus not valuable with routine biopsies.

    Full Text Available Well differentiated liposarcoma (WDLS is the commonest subtype of liposarcoma. Recognised subtypes of WDLSs are lipoma-like, sclerosing, spindle cell and inflammatory. The inflammatory variant of WDLS also known as “lymphocyte-rich liposarcoma” is rare. We present a case of inflammatory WDLS occurring in the retroperitoneum, in a patient with a past history of non-Hodgkin lymphoma. We outline the histological features, discuss the differential diagnoses and highlight the diagnostic pitfalls in interpretation of this lesion on fine needle biopsy.

    2009-01-01

    There is no consensus on recommendations for the treatment of relapsed and refractory indolent non-Hodgkin lymphoma (NHL). Bendamustine hydrochloride (bendamustine) has recently been approved for treatment of these patients. Bendamustine is a uniquely structured alkylating agent that lacks cross-resistance with other alkylators. This agent has a high degree of activity against a variety of tumor cell lines. Clinically, bendamustine has demonstrated activity against indolent NHL, chronic lymphocytic lymphoma, multiple myeloma and mantle cell lymphoma. Moreover, studies have validated its activity in patients with indolent NHL who are resistant to purine analogs and rituximab. The cytotoxic activity of bendamustine has been shown to be synergistic with rituximab in hematological malignancies. The incidence of alopecia is significantly less than with other alkylating agents. Myelosuppression is the major toxicity associated with bendamustine

    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.

    Whilst many patients with indolent Non-Hodgkin's Lymphoma (NHL) can achieve clinical remissions to first-line chemotherapy and/or radiotherapy, most will relapse. Current treatment options for relapsing patients are limited since most patients become resistant to repeated chemotherapy. Death usually occurs within 10 years of diagnosis. Overall, these disappointing results have not changed significantly in a quarter of a century and clearly advocate the urgent priority to research into potential new therapeutic approaches into this diverse and increasingly prevalent group of human tumours. Radioimmunotherapy (RIT) is currently under investigation as a new approach for the treatment of this disease. In this form of treatment, radionuclide-labeled monoclonal antibodies are able to deliver selective systemic irradiation by recognising tumour-associated antigens. The use of RIT with radiolabeled anti-CD20 antibodies in patients with recurrent B-cell lymphoma has resulted in extremely high rates of durable complete remissions. The optimal approach and mechanisms of action of successful RIT remain however largely unknown. The work described in this thesis has focused on clarifying some of the important determinants and mechanisms of effective RIT of syngeneic B-cell lymphoma, both in vivo and in vitro. A successful animal model of RIT in B cell lymphomas was established by initially generating a panel of antibodies against mouse B cell antigens. The in vitro characteristics of these antibodies have been compared with their subsequent performance, in biodistribution studies and RIT in vivo. For the first time in an in vivo model the relative contributions of antibody and irradiation are described. Some antibodies including anti-MHC Class II were shown to be effective delivery vehicles of low doses of Iodine-131. These antibodies, which appear to be inactive delivery vehicles can cure animals with low burdens of tumour. However antibodies such as anti-idiotype and anti-CD40

    The purpose of this review is to discuss and illustrate the spectrum of appearances of extranodal lymphoma in the thorax, including the lungs, pleura, heart, thymus, chest wall, thoracic spine, and breast, using current cross-sectional imaging techniques, such as multidetector computed tomography, positron-emission tomography/computed tomography, magnetic resonance imaging, and sonography. Extranodal lymphoma can affect any organ or tissue in the thorax, and can be mistaken for other inflammatory or neoplastic conditions. This review should alert the radiologist to consider extranodal lymphoma in the appropriate clinical setting to ensure timely diagnosis, correct staging, and accurate post-treatment evaluation to optimize treatment regimens.

    Non-Hodgkin's lymphomas is a heterogeneous group of neoplasms. The lymphomas have various origins: from B and T cells. REAL/WHO classification system of NHL subdivided these diseases into lymphoma from precursor and peripheral lymphocytes. Clinical course may be: very aggressive and aggressive (generally - curable disease); and indolent lymphoma (generally - curable disease). The treatment of each subtype NHL is different, correct diagnosis is critically important. In the treatment of aggressive NHL are used combined chemotherapy, the addition of monoclonal antibody has greatly increased its efficacy. There are several therapeutic strategies to treat indolent NHL. The treatment of asymptomatic indolent lymphoma offers no benefit, and these patients may be observed. Once symptomatic, front-line therapy consist of single agent or combination chemotherapy, often combined with monoclonal antibody. The monoclonal antibodies have revolutionized the treatment of NHL. Monoclonal antibody fixes the antigen on the membrane o f the lymphoma cells. Monoclonal antibodies there are unconjugated, used alone or combined with chemotherapy (immunochemotherapy) or combined with immunotoxins or radionuclides (radioimmunotherapy). This is the progress in the treatment of lymphoma. (authors)

    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.

    Full Text Available We evaluated the expression of 10 adhesion molecules on peripheral blood tumor cells of 17 patients with chronic lymphocytic leukemia, 17 with mantle-cell lymphoma, and 13 with nodal or splenic marginal B-cell lymphoma, all in the leukemic phase and before the beginning of any therapy. The diagnosis of B-cell non-Hodgkin's lymphomas was based on cytological, histological, immunophenotypic, and molecular biology methods. The mean fluorescence intensity of the adhesion molecules in tumor cells was measured by flow cytometry of CD19-positive cells and differed amongst the types of lymphomas. Comparison of chronic lymphocytic leukemia and mantle-cell lymphoma showed that the former presented a higher expression of CD11c and CD49c, and a lower expression of CD11b and CD49d adhesion molecules. Comparison of chronic lymphocytic leukemia and marginal B-cell lymphoma showed that the former presented a higher expression of CD49c and a lower expression of CD11a, CD11b, CD18, CD49d, CD29, and CD54. Finally, comparison of mantle-cell lymphoma and marginal B-cell lymphoma showed that marginal B-cell lymphoma had a higher expression of CD11a, CD11c, CD18, CD29, and CD54. Thus, the CD49c/CD49d pair consistently demonstrated a distinct pattern of expression in chronic lymphocytic leukemia compared with mantle-cell lymphoma and marginal B-cell lymphoma, which could be helpful for the differential diagnosis. Moreover, the distinct profiles of adhesion molecules in these diseases may be responsible for their different capacities to invade the blood stream.

    We present the clinical and radiological findings in 12 HIV-positive patients with gastrointestinal involvement secondary to non-Hodgkin's lymphoma, focusing on the value of the different diagnostic techniques employed (barium studies, ultrasonography and CT) and the differential diagnosis in view of our findings in these patients. We have reviewed the case histories of 58 HIV-positive patients diagnosed as having non-Hodgkin's lymphoma focusing on the results of barium studies, ultrasonography and CT scanning. According to barium studies, ultrasonography and CT, 12 patients (21%) presented gastrointestinal involvement, located in stomach (n=3D5), duodenum (n=3D2), small bowel (n=3D4), mesentery (n=3D1) and perianal region ( n=3D1). Enlarged abdominal lymph nodes were detected in 10 patients (83%). Six patients (50%) presented extraintestinal lymphomatous involvement and four (30%) had extraabdominal involment. Barium studies and CT were useful in the detection of the lesions of all the patients in whom these techniques were performed. CT also allowed the assessment of extraintestinal involvement. Ultrasonography showed poor sensitivity in the study of gastrointestinal involvement, but was effective in the detection of adenophathy. (Author) 27 refs

    Background: Intramuscular manifestations of malignant immuno proliferative diseases (IMMID) are very rare. Purpose: To determine the prevalence and the clinical features of IMMID in a large series of patients, and to analyze their radiological appearances. Material and Methods: Between 1997 and 2007, 20 patients with IMMID (non-Hodgkin lymphoma [NHL], n=14, and myeloma, n=6) were identified. All patients underwent computed tomography (CT). In five cases, magnetic resonance imaging (MRI) was additionally performed. Results: Clinically, 16 patients presented with local pain and soft-tissue swelling. In four patients, IMMID was found incidentally. The most common site was the erector spinae muscle, followed by the iliopsoas and pelvic muscles. In 13 cases of IMMID, diffuse mass-forming muscle infiltration was found. Focal intramuscular masses were identified in seven cases. Conclusion: NHL mostly manifests as diffuse muscle enlargement, whereas myelomas form focal intramuscular masses. Nevertheless, CT and MR appearances are nonspecific and can be misinterpreted as muscle sarcoma or inflammatory disease. Although rare, muscle involvement should be considered in the differential diagnosis of muscle disorders in patients with non-Hodgkin lymphoma and myeloma

    Full Text Available Despite highly active antiretroviral therapy (HAART, AIDS related lymphoma (ARL occurs at a significantly higher rate in patients infected with the Human Immunodeficiency Virus (HIV than in the general population. HIV-infected macrophages are a known viral reservoir and have been shown to have lymphomagenic potential in SCID mice; therefore, there is an interest in determining if a viral component to lymphomagenesis also exists. We sequenced HIV-1 envelope gp120 clones obtained post mortem from several tumor and non-tumor tissues of two patients who died with AIDS-related Non-Hodgkin's lymphoma (ARL-NH. Similar results were found in both patients: 1 high-resolution phylogenetic analysis showed a significant degree of compartmentalization between lymphoma and non-lymphoma viral sub-populations while viral sub-populations from lymph nodes appeared to be intermixed within sequences from tumor and non-tumor tissues, 2 a 100-fold increase in the effective HIV population size in tumor versus non-tumor tissues was associated with the emergence of lymphadenopathy and aggressive metastatic ARL, and 3 HIV gene flow among lymph nodes, normal and metastatic tissues was non-random. The different population dynamics between the viruses found in tumors versus the non-tumor associated viruses suggest that there is a significant relationship between HIV evolution and lymphoma pathogenesis. Moreover, the study indicates that HIV could be used as an effective marker to study the origin and dissemination of lymphomas in vivo.

    A retrospective analysis was done for 69 patients with Stage I and II non-Hodgkin lymphoma who were treated from May 1981 to December 1990, in the Department of Radiadtion Oncology, Korea University Hospital. We used Ann Arbor Staging system and Working Formulation for histological classification. Forty-three patients(43/69, 62.3%) were Stage I and 26 patients (26/69, 37.7%) were Stage II, and B symptom was found in 10.1%(7/69). Local control rate for all patients was 88.4%(61/69), with 80% (12/15) for nodal lymphoma and 90.7%(49/54) for extra nodal lymphoma. The total failure rate was 34.8%(24/69). Five of 24 (20.8%) patients who were failed developed local failure only, 12.5%(3/24) local failure with distant failure, and distant failure only were found in 66.7%(16/24). Between nodal lymphoma and extra nodal lymphoma, there was no significant survival difference, but extra nodal lymphoma showed higher incidence

    Eighteen children suffering from Non-Hodgkin's lymphoma were studied. Of these eighteen children, eight (44.4 percent) had well differentiated diffuse lymphocytic lymphoma and six (33.3 percent) had poorly differentiated diffuse lymphocytic lymphoma and four (22.3 percent) had histiocytic lymphoma. Histological study was based on the concept of Rappaport (1966). Children belonging to Stage IIB were treated with radiotherapy followed by combination chemotherapy and those with Stage IIIB and Stage IVB were treated with combination chemotherapy utilising cyclophosphamide, oncovin and prednisolone. The result of combination chemotherapy (COP) was dramatic and appears to have resulted in long term disease free survival. In well differentiated diffuse lymphocytic lymphoma in Stage IIB the life expectancy of two children was extended to 12 years with well maintained remission for 9.5 years. Recurrence rate was 44.4 percent. Death rate was 61.1 percent and median survival time was 26.7 months. In histiocytic lymphomas the results were unsatisfactory. Median survival time was 9.5 months.

    Radiation therapy has its major role in the management of patients with localized non-Hodgkin's lymphoma. For patients with stage I-II malignant lymphoma with low-grade malignancy, five-year survival rates after radiation therapy are 75 - 100 %. For patients with intermediate malignancy, five-year survival rates after radiation therapy alone are 70 - 100 % for patients with pathological stage I - II and 45 - 75 % for clinical stage I - II. Radiation dose to the tumor at least 40 Gy was required to produce consistent local control. Initial use of chemotherapy with radiation therapy is indicated to improve relapse-free survival rate for patients with clinical stage I - II, as well as pathological stage I - II. (author)

    Background. Primary lymphoma of the colon is rare, constituting 0.4% of primary colonic malignancies and usually involves cecum or rectum. The aim of this paper is to present the role and the importance of double contrast barium enema (DCBE) in the diagnostic process. Case report. A 77 years old male was admitted because of suspected inflammation in the area of total endoprosthesis of the left hip, inserted ten years before. Listeria monocytogenes was isolated from the aspirate and the patient treated with antibiotics. Twenty years ago the patient underwent nephrectomy because of hypernephroma of left kidney. At the time of admission he had sideropenic anaemia and he was febrile. Conclusion. The patient underwent many diagnostic procedures: ultrasound (US), computed tomography (CT), double contrast barium enema, which showed a tumour in the cecum, small bowel follow-through and scintigraphy. The diagnosis of primary non-Hodgkin lymphoma was established by histology after biopsy at colonoscopy. (author)

    Epidemiologic studies of non-Hodgkin lymphoma (NHL) in Eastern Europe are scarce in the literature. We report the experience of the "Ion Chiricuta" Institute of Oncology in Cluj-Napoca (IOCN), Romania, in the diagnosis and outcome of patients with NHL. We studied 184 consecutive NHL patients diagnosed in the Pathology Department of IOCN during the years 2004-2006. We also obtained epidemiological data from the Northwestern (NW) Cancer Registry. In the IOCN series, the most common lymphoma subtype was diffuse large B-cell lymphoma (43.5%), followed by the chronic lymphocytic leukaemia/small lymphocytic lymphoma (21.2%). T-cell lymphomas represented a small proportion (8.2%). The median age of the patients was 57 years, with a male-to-female ratio of 0.94. Patients with indolent B-cell lymphomas had the best overall survival, whereas those with mantle cell lymphoma had the worst survival. The NW Cancer Registry data showed that the occurrence of NHL in the NW region of Romania was higher in men [world age-standardized incidence rate/100 000 (ASR)-5.9; 95% CI 5.1-6.6] than in women (ASR-4.1; 95% CI 3.5-4.7) with age-standardized male-to-female ratio of 1.44 (p = 0.038). Chronic lymphocytic leukaemia/small lymphocytic lymphoma was the most common NHL in the NW region of Romania, accounting for 43% of all cases, followed by diffuse large B-cell lymphoma (36%). The 5-year, age-standardized cumulative relative survival for NHL in the County of Cluj in NW Romania, for the period of 2006-2010, was 51.4%, with 58.4% survival for men and 43.2% for women. Additional studies of NHL in Eastern Europe are needed. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

    Purpose: To assess the role of radiation therapy in the treatment of primary localized (Stage I: 24 cases and Stage II: 13 cases) non-Hodgkin's Lymphoma (NHL) of the oral cavity. Methods and Materials: In total, 37 patients (27 male, 10 female) with primary localized NHL of the oral cavity have been treated with radiotherapy alone (23 cases) or radiation with chemotherapy (14 cases). The age range was 29 to 86 years (median: 65). Clinical and treatment variables with potential prognostic significance for survival were evaluated by univariate and multivariate analysis. Of the 37 patients, 31 (84%) had intermediate-grade lymphomas and six (14%) had high-grade lymphomas. Four patients showed necrotic ulcer in the central portion of the hard palate. Results: The 5-year actuarial survival rate for all cases was 73%. The 5-year survival rates for intermediate-grade and high-grade lymphoma were 85% and 14%, respectively. Significant prognostic factors identified by the multivariate analysis were histologic grade of malignancy (p = 0.02) and central necrotic ulcer in the tumor (p = 0.02). Chemotherapy did not improve survival (p = 0.41). Conclusions: Our analysis suggests that radiotherapy alone may be approved as the treatment for localized oral NHL with no ulceration and intermediate histology. However, patients with high-grade lymphoma and/or necrotic ulcer are difficult to cure with radiation alone and aggressive treatment should be advocated to improve survival

    The purpose of this study was to explore the association between X-ray repair cross-complementing group 1 (XRCC1)gene polymorphism and non-Hodgkin's lymphoma risk. A total of 282 non-Hodgkin's lymphoma (NHL) patients and 231 normal controls were used to investigate the effect of three XRCC1 gene polymorphisms (rs25487, rs25489, rs1799782) on susceptibility to non-Hodgkin's lymphoma. Genotyping was performed by using SNaPshot method. All statistical analyses were done with R software. Genotype and allele frequencies of XRCC1 were compared between the patients and controls by using the chi-square test. Crude and adjusted odd ratios and 95% confidence intervals were calculated by using logistic regression on the basis of genetic different models. For four kinds of NHL, subgroup analyses were also conducted. Combined genotype analyses of the three XRCC1 polymorphisms were also done by using logistic regression. The results showed that the variant genotype frequency was not significantly different between the controls and NHL or NHL subtype cases. Combined genotype analyses of XRCC1 399-280-194 results showed that the combined genotype was not associated with risk of NHL overall, but the VT-WT-WT combined genotype was associated with the decreased risk of T-NHL (OR: 0.21; 95%CI (0.06-0.8); P = 0.022), and the WT-VT-WT combined genotype was associated with the increased risk of FL(OR:15.23; 95%CI (1.69-137.39); P = 0.015). It is concluded that any studied polymorphism (rs25487, rs25489, rs1799782) alone was not shown to be rela-ted with the risk of NHL or each histologic subtype of NHL. The combined genotype with mutation of three SNP of XRCC1 was not related to the risk of NHL. However, further large-scale studies would be needed to confirm the association of decreased or increased risk for T-NHL and FL with the risk 3 combined SNP mutants of XRCC1 polymorphism.

    The objective was to determine whether population mixing produced by large, non-nuclear construction projects in rural areas is associated with an increase in childhood leukaemia and non-Hodgkin's lymphoma. A study was undertaken of the incidence of leukaemia and non-Hodgkin's lymphoma among children living near large construction projects in Britain since 1945, situated more than 20 km from a population centre, involving a workforce of more than 1000, and built over three or more calendar years. A 37% excess of leukaemia and non-Hodgkin's lymphoma at 0-14 years of age was recorded during construction and the following calendar year. The excesses were greater at times when construction workers and operating staff overlapped (72%), particularly in areas of relatively high social class. For several sites the excesses were similar to or greater than that near the nuclear site of Sellafield (67%), which is distinctive in its large workforce with many construction workers. Seascale, near Sellafield, with a ninefold increase had an unusually high proportion of residents in social class I. The findings support the infection hypothesis and reinforce the view that the excess of childhood leukaemia and non-Hodgkin's lymphoma near Sellafield has a similar explanation. (author)

    Purpose To analyze outcomes of hematopoietic cell transplantation (HCT) in T-cell non-Hodgkin lymphoma. Patients and Methods Outcomes of 241 patients (112 anaplastic large-cell lymphoma, 102 peripheral T-cell lymphoma not otherwise specified, 27 angioimmunoblastic T-cell lymphoma) undergoing autologous HCT (autoHCT; n = 115; median age, 43 years) or allogeneic HCT (alloHCT; n = 126; median age, 38 years) were analyzed. Primary outcomes were nonrelapse mortality (NRM), relapse/progression, progression-free survival (PFS), and overall survival (OS). Patient, disease, and HCT-related variables were analyzed in multivariate Cox proportional hazard models to determine association with outcomes. Results AutoHCT recipients were more likely in first complete remission (CR1; 35% v 14%; P = .001) and with chemotherapy-sensitive disease (86% v 60%; P < .001), anaplastic large-cell histology (53% v 40%; P = .04), and two or fewer lines of prior therapy (65% v 44%; P < .001) compared with alloHCT recipients. Three-year PFS and OS of autoHCT recipients beyond CR1 were 42% and 53%, respectively. Among alloHCT recipients who received transplantations beyond CR1, 31% remained progression-free at 3 years, despite being more heavily pretreated and with more refractory disease. NRM was 3.5-fold higher (95% CI, 1.80 to 6.99; P < .001) for alloHCT. In multivariate analysis, chemotherapy sensitivity (hazard ratio [HR], 1.8; 95% CI, 1.16 to 2.87) and two or fewer lines of pretransplantation therapy (HR, 5.02; 95% CI, 2.15 to 11.72) were prognostic of survival. Conclusion These data describe the roles of autoHCT and alloHCT in T-cell non-Hodgkin lymphoma and suggest greater effectiveness earlier in the disease course, and limited utility in multiply relapsed disease. Notably, autoHCT at relapse may be a potential option for select patients, particularly those with anaplastic large-cell lymphoma histology. PMID:23897963

    Lymphomas are the third malignancy in children, and within them non-Hodgkin lymphoma (NHL) accounts for just 7% of cancers in children under 15 years old. Chemotherapy is currently the treatment of choice. The objective of this study is to analyze the toxicity caused by the treatment in pediatric patients diagnosed with NHL. A retrospective study was conducted on patients diagnosed with mature B-cell NHL, treated according to the LMB protocol 2001, from January 2007 to February 2014. Data concerning the diagnosis, treatment and toxicities that developed in the patients during the same period were collected. A total of 20 mature B-cell NHL cases were diagnosed: 16 Burkitt lymphomas, 2 diffuse large cell lymphomas and 2 mature leukemias. Almost two-thirds (65%) of patients were classified in a high grade stage (iii-iv) at diagnosis. Serious infectious processes, severe myelosuppression, liver abnormalities, and mucositis were the most frequent toxicities. Overall survival was 95% (19/20). One patient died of causes unrelated to the illness. Despite the excellent survival rate, most patients diagnosed with NHL mature B cells experience grade iii and iv toxicities during treatment.

    Full Text Available Abstract Introduction Non-Hodgkin lymphoma primarily originating from the bone is exceedingly rare. To our knowledge, this is the first report of primary bone lymphoma presenting with progressive cord compression from an origin in the cervical spine. Herein, we discuss the unusual location in this case, the presenting symptoms, and the management of this disease. Case presentation We report on a 23-year-old Caucasian-American man who presented with two months of night sweats, fatigue, parasthesias, and progressive weakness that had progressed to near quadriplegia. Magnetic resonance (MR imaging demonstrated significant cord compression seen primarily at C7. Surgical management, with corpectomy and dorsal segmental fusion, in combination with adjuvant chemotherapy and radiation therapy, halted the progression of the primary disease and preserved neurological function. Histological analysis demonstrated an aggressive anaplastic large cell lymphoma. Conclusion Isolated primary bony lymphoma of the spine is exceedingly rare. As in our case, the initial symptoms may be the result of progressive cervical cord compression. Anterior corpectomy with posterolateral decompression and fusion succeeded in preventing progressive neurologic decline and maintaining quality of life. The reader should be aware of the unique presentation of this disease and that surgical management is a successful treatment strategy.

    Lymphomas constitute the second most common indication for high dose therapy (HDT) followed by autologous hematopoietic cell transplantation (auto-HCT). The intent of administering HDT in these heterogeneous disorders varies from cure (e.g., in relapsed aggressive lymphomas) to disease control (e.g., most indolent lymphomas). Regardless of the underlying histology or remission status at transplantation, disease relapse remains the number one cause of post auto-HCT therapy failure and mortality. The last decade has seen a proliferation of clinical studies looking at prevention of post auto-HCT therapy failure with various maintenance strategies. The benefit of such therapies is in turn dependent on disease histology and timing of transplantation. In relapsed, chemosensitive diffuse large B-cell lymphoma (DLBCL), although post auto-HCT maintenance rituximab seems to be safe and feasible, it does not provide improved survival outcomes and is not recommended. The preliminary results with anti- programmed death -1 (PD-1) antibody therapy as post auto-HCT maintenance in DLBCL is promising but requires randomized validation. Similarly in follicular lymphoma, maintenance therapies including rituximab following auto-HCT should be considered investigational and offered only on a clinical trial. Rituximab maintenance results in improved progression-free survival but has not yet shown to improve overall survival in mantle cell lymphoma (MCL), but given the poor prognosis with post auto-HCT failure in MCL, maintenance rituximab can be considered on a case-by-case basis. Ongoing trials evaluating the efficacy of post auto-HCT maintenance with novel compounds (e.g., immunomodulators, PD-1 inhibitors, proteasome inhibitors and bruton’s tyrosine kinase inhibitors) will likely change the practice landscape in the near future for B cell non-Hodgkin lymphomas patients following HDT and auto-HCT.

    Full Text Available Abstract In this study 15 banked samples of HIV-related Non-Hodgkin's Lymphoma (NHL cases were tested for HIV co-receptor usage and SDF1 3'A polymorphism. Reportable tropism from 9 plasma samples had 1 (11.1% HIV case with CXCR4 and 8 (88.9% with CCR5 usage, even though most of the cases occurred at a late stage of HIV (2/3 had CD4 counts below 200, where expected CXCR4 usage would be 60%. Based on the expected proportion of less than 50% CCR5 in chronically infected individuals, this would suggest that in NHL may be associated with CCR5 usage (P = 0.04.

    Evidence is emerging that obesiy and weight gain may affect the prognosis of several types of cancer. We investigated the impact of body mass index (BMI) as well as pre-and postdiagnosis weight changes on non-Hodgkin lymphoma (NHL) prognosis. A cohort of 573 female incident NHL cases diagnosed during 1996-2000 in Connecticut was followed for a median of 7.8 yr. Self-reported height and weight at 3 time points before and after diagnosis were collected. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated using proportional hazard models adjusting for factors believed to be associated with overall survival of NHL. Underweight (BMI treatment were found to have a poorer survival.

    The association between cancer and aids in children is rare. Perhaps non-Hodgkin lymphoma (NHL) is the most common cancer in pediatric HIV positive patients. We report the case of a 5-year-old boy with NHL; stage IV (due to bone-marrow and Central Nervous System involvement). As his parents died of aids, this diagnosis was confirmed in the patient. Medical treatment was difficult because of the severe toxicity of chemotherapy and antiretroviral drugs. The patient presented a relapse during treatment and died. This type of pathology has been increasing in the last few years. Every case provides us with experience and better support to find out guidelines for the diagnosis and therapy for this disease

    Patients with childhood leukemia surviving into adulthood have elevated risk of developing thyroid cancer, brain cancer, and non-Hodgkin lymphoma (NHL); these risks cannot automatically be extrapolated to patients surviving adult leukemia. We tested whether survivors of adult leukemia...... are at increased risk of developing thyroid cancer, brain cancer, and NHL. We included the entire adult Danish population (14 years of age or older), in a 28-year follow-up period from 1980 through 2007, composed of 6 542 639 persons; during this period, 18 834 developed adult leukemia, 4561 developed thyroid...... cancer, 13 362 developed brain cancer, and 15 967 developed NHL. In nested studies using Cox regression models on individual participant data, we found that, after adult leukemia, the multivariate adjusted hazard ratios were 4.9 (95% confidence interval [CI], 2.8-8.5) for thyroid cancer, 1.9 (95% CI, 1...

    In a previous study of 50 patients with non-Hodgkin lymphoma (NHL) it was shown that the inhomogeneous appearance of a tumor at MR imaging strongly indicated a high malignancy grade. In this study of 33 patients with NHL, the administration of an i.v. contrast medium, Gadolinium-DTPA, improved the subjective detectability of the inhomogeneities. A method of quantifying the degree of inhomogeneity in the tumors (inhomogeneity index, IH-index) was developed and tested. The mean value of IH-index in the T2-weighted image before contrast medium administration, and of the T1-weighted image after contrast medium administration, as well as the IH-index value in the T2-weighted image before contrast medium administration alone, was able to discriminate well between low- and high-grade NHL. This method of quantifiying the degree of inhomogeneity in tumors improved sensitivity in detecting high-grade NHL. (orig.)

    Background: Combined modality therapy with chemotherapy and radiotherapy has become increasingly popular in the management of solid malignancies. However, unexpected toxicities may arise from their interactions. Methods and Materials: We report the case of a young woman with a large mediastinal non-Hodgkin's lymphoma who underwent high-dose chemotherapy with autologous bone marrow transplantation and involved field radiotherapy, and who developed radiation myelopathy after a latent period of only 3 months. The spinal cord dose did not exceed 40.3 Gy in 22 fractions over 4.5 weeks, which is well within accepted tolerance limits. She had no other identifiable risk factors for radiation myelopathy, suggesting an adverse drug-radiation interaction as the most likely cause of her injury. Results and Conclusions: This represents the first report of radiation myelopathy at accepted safe radiation doses following high-dose chemotherapy with autologous bone marrow transplantation, and we recommend caution in the choice of radiotherapeutic dose in this setting

    We examined eight patients with primary spinal epidural non-Hodgkin's lymphoma presenting with spinal cord compression and proven histologically after laminectomy (7 cases) or biopsy (1 case) by MRI. The most common findings were an isointense or low signal relative to the spinal cord on T1-weighted images (T1WI) and high signal on T2-weighted images (T2WI). Spinal cord compression, vertebral bone marrow and paravertebral extension were assessed. Contrast enhancement was intense in seven of the eight cases and homogeneous in all of them. T2WI (performed in 2 cases) may be useful to distinguish metastatic carcinomas and sarcomas. T1WI demonstrated the full extent of the epidural lesion, which was well-delineated in all cases. When the paravertebral extension is not well-defined, a study with contrast medium should be performed. (orig.). With 3 figs., 1 tab

    Effective treatment of Hodgkin's disease requires the determination of the extent of the disease. This usually involves staging laparotomy, which includes splenectomy and biopsies of the para-aortic lymph nodes, liver, and bone marrow. Absence of the spleen predisposes a person to fulminant septicemia from encapsulated bacteria, a risk even greater in patients undergoing treatment for Hodgkin's disease. For this reason, some investigators have suggested that spleens not be removed for diagnosis but, rather, that they be included within the fields of radiation, which would preserve normal splenic function. We present a case of fatal spontaneous pneumococcal sepsis in a patient with splenic atrophy; the sepsis occurred 12 years after successful treatment of Hodgkin's disease by total nodal and splenic irradiation. A retrospective study of patients treated for Hodgkin's and non-Hodgkin's lymphomas indicated that atrophy and functional asplenia may be an important sequela of splenic irradiation

    The objective of this study was to examine indirect costs and workplace productivity loss (defined as an aggregate measure of absenteeism, short-term disability, and long-term disability days) associated with non-Hodgkin lymphoma (NHL) from a societal perspective in a commercially insured working-age United States population. The MarketScan(®) Commercial Claims and Encounters and Health and Productivity Management Databases (2007-2013) were used in this study, with controls matched 3:1 to NHL patients. In comparison to controls, NHL patients incurred significantly more workplace productivity loss (31.99 days; 95% CI: 25.24 days, 38.73 days; p workplace productivity and higher associated indirect costs.

    Full Text Available This paper describes primary subcutaneous infection caused by N. abscessus in a 60-year-old male patient with the history of non-Hodgkin’s lymphoma and chronic lymphocytic leukemia. The patient was presented with pain and swelling in his left thigh for 45 days. Soft tissue ultrasonography showed a heterogeneous and hypoechoic mass consistent with an abscess. Gram-positive and branched filamentous bacilli, along with neutrophils, were identified in gram-stained smears of the pus. Pus culture was positive for Gram-positive bacilli, which identified as N. abscessus. Initially, the patient was treated with trimethoprim-sulfamethoxazole. Due to insufficient clinical response, ceftriaxone was added for two weeks. Then, the patient was prescribed a 3-month course of trimethoprim-sulfamethoxazole. It is important to start appropriate and effective treatment as soon as possible in patients with immunosuppression. [Dis Mol Med 2016; 4(3.000: 31-33

    Interstitial lung diseases belong to a group of diseases that typically exhibit a subacute or chronic progression but that may cause acute respiratory failure. The male patient, who was 37 years of age and undergoing therapy for non-Hodgkin's lymphoma, was admitted with cough, fever, dyspnea and acute hypoxemic respiratory failure. Mechanical ventilation and antibiotic therapy were initiated but were associated with unfavorable progression. Thoracic computed tomography showed bilateral pulmonary "ground glass" opacities. Methylprednisolone pulse therapy was initiated with satisfactory response because the patient had used three drugs related to organizing pneumonia (cyclophosphamide, doxorubicin and rituximab), and the clinical and radiological symptoms were suggestive. Organizing pneumonia may be idiopathic or linked to collagen diseases, drugs and cancer and usually responds to corticosteroid therapy. The diagnosis was anatomopathological, but the patient's clinical condition precluded performing a lung biopsy. Organizing pneumonia should be a differential diagnosis in patients with apparent pneumonia and a progression that is unfavorable to antimicrobial treatment. PMID:23917942

  18. Genetic variation in DNA repair pathways and risk of non-Hodgkin's lymphoma.

    Full Text Available Molecular and genetic evidence suggests that DNA repair pathways may contribute to lymphoma susceptibility. Several studies have examined the association of DNA repair genes with lymphoma risk, but the findings from these reports have been inconsistent. Here we provide the results of a focused analysis of genetic variation in DNA repair genes and their association with the risk of non-Hodgkin's lymphoma (NHL. With a population of 1,297 NHL cases and 1,946 controls, we have performed a two-stage case/control association analysis of 446 single nucleotide polymorphisms (SNPs tagging the genetic variation in 81 DNA repair genes. We found the most significant association with NHL risk in the ATM locus for rs227060 (OR = 1.27, 95% CI: 1.13-1.43, p = 6.77×10(-5, which remained significant after adjustment for multiple testing. In a subtype-specific analysis, associations were also observed for the ATM locus among both diffuse large B-cell lymphomas (DLBCL and small lymphocytic lymphomas (SLL, however there was no association observed among follicular lymphomas (FL. In addition, our study provides suggestive evidence of an interaction between SNPs in MRE11A and NBS1 associated with NHL risk (OR = 0.51, 95% CI: 0.34-0.77, p = 0.0002. Finally, an imputation analysis using the 1,000 Genomes Project data combined with a functional prediction analysis revealed the presence of biologically relevant variants that correlate with the observed association signals. While the findings generated here warrant independent validation, the results of our large study suggest that ATM may be a novel locus associated with the risk of multiple subtypes of NHL.

    In 38 patients with non-Hodgkin's lymphoma, involvement of the central nervous system (CNS) by malignant lymphoma developed during an eight year period. All patients had lymphomatous meningitis; clinical involvement of the spinal nerves or cranial nerves suggested the diagnosis. Spinal fluid was abnormal in 97% of the patients although a positive cytology could be documented in only 67% by lumbar puncture. The histology in 82% of the patients was diffuse. Involvement of the CNS in nodular lymphoma was uncommon (3%), and the histology in virtually all of these patients had converted to diffuse. At the time of diagnosis of CNS disease, 95% of the patients had other evidence of advanced disease; 66% had bone marrow involvement. In only 18% of the patients did CNS disease develop while they werin clinical remission. Eighty-five percent of the patients treated with whole brain irradiation and intrathecal chemotherapy had a good clinical response. Knowledge of these risk factors permits definition of a group of patients who may benefit from CNS prophylaxis

    Purpose: The purpose of this study was to assess the efficacy of a 2 Multiplication-Sign 2 Gy (total dose, 4 Gy) palliative radiation therapy (RT) regimen for treating patients with indolent non-Hodgkin lymphoma (NHL) in terms of response rate, response duration, and symptom relief. Methods and Materials: A retrospective chart review was conducted. Between 2003 and 2007, 54 patients with NHL were treated to 85 anatomical sites with a 2 Multiplication-Sign 2 Gy palliative regimen. Local response was assessed by clinical and/or radiographic data. Symptoms before and after treatment for each site treated were obtained from clinical notes in patient medical records. Median follow-up time was 1.3 years. Results: For the 54 patients, the median age at time of treatment was 71.1 years old, and 57% of them were male. Of the 85 disease sites treated, 56% of sites had indolent histology, 28% of sites were diagnosed with chronic lymphocytic leukemia (CLL), 13% of sites had aggressive histology, and 2% of sites were shown to have other histology. Overall response rate (ORR) was 81% (49% complete response [CR], 32% partial response [PR]). The 2-year rate for freedom from local progression was 50% (95% CI, 37%-61%). The ORR for follicular lymphoma, Mucosa associated lymphoid tissue (MALT), and marginal zone lymphoma (MZL) histology was 88%, compared with a 59% rate for CLL histology (p = 0.005). While the ORR was similar for tumors of different sizes, the CR rate for patients with tumors <5 cm tended to be higher than those with tumors >10 cm (CR rate of 57% vs. 27%, respectively; p = 0.06). For the 48 sites with clearly documented symptoms at pretreatment, 92% of sites improved after low-dose RT. Conclusions: Short-course low-dose palliative radiotherapy (2 Multiplication-Sign 2 Gy) is an effective treatment that results in high response rates for indolent non-Hodgkin lymphoma. This treatment regimen provides effective symptomatic relief for tumor bulk of all sizes.

  1. Clinical and economic aspects of the use of rituximab in non-Hodgkin's lymphoma

    2014-09-01

    Full Text Available Non-Hodgkin's lymphoma (NHL consists of a group of neoplasias involving mainly B cells and represents 90% of all lymphomas. The current available therapy is based on chemotherapy associated with the monoclonal antibody rituximab (Mab Thera(r, which targets the CD20 protein, present in over 80% of NHL mature B cells. Recent clinical reports show a preference for combining the benefits of immunotherapy and adjuvant chemotherapy, thus generating safe and effective alternative treatments. The current review aimed at evaluating various aspects related to the use of rituximab for NHL, highlighting the possible inhibitory mechanisms of cell proliferation, the achieved clinical results, and the expected clinical and economic outcomes of treatments. The results from clinical tests indicate the need for a better understanding of the critical mechanisms of action of this antibody, which may maximize its therapeutic efficacy. This therapy not only represents a viable option to treat most types of NHLs, especially when associated with conventional chemotherapy, but also offers cost-utility and cost-effectiveness advantages.

    To evaluate the frequently of low attenuation area in enhanced CT scans of non-Hodgkin lymphoma(NHL) and to find out if there is any pertinent relationship between this and the histopathologic classification. The authors reviewed CT scans in the newly-diagnosed 53 patients with NHL. We defined the low attenuation area as the one with CT attenuation value lower than that of the muscle, surrounding lesion, or other lymph nodes after contrast enhancement. NHL with the low attenuation areas were correlated with the histopathologic findings according to the classification based on the Working Formulation and the frequency of the lesion was evaluated. Of the 53 patients, the low attenuation area was found in 13 patients (25%) at CT. The histopathologic classification could be made in 12 patients, among whom one patient was classified as low-grade, six as intermediate-grade, and five as high-grade. Concerning the specific cell typing, the diffuse large cell type was most common in intermediate-grade NHL seen in five patients and the large cell, immunoblastic type was most common in high-grade NHL seen in three patients. The authors concluded that the low attenuation area within lymphoma is not an infrequent finding at CT, and there was no statistically significant correlation between this finding and the prognostic grading of the Working Formulation.

    Central nervous system (CNS) prophylaxis is required during initial treatment of non-Hodgkin lymphoma (NHL) subtypes that carry a high risk of CNS involvement. Intrathecal (IT) liposomal cytarabine, a formulation with prolonged half-life, has been shown to be safe and effective in the treatment of meningeal disease in patients with high-grade lymphoma. We retrospectively reviewed all adult patients with high-grade NHL that received prophylactic therapy with IT liposomal cytarabine and developed neurologic complications in our institution between April 2007 and May 2009. We recorded information on hospital admission, chemotherapy regimens, clinical features, neuroimaging, cerebrospinal fluid, neurophysiology data, and outcome. Neurotoxicity was graded according to the National Cancer Institute Common Toxicity Criteria (NCI-CTC). Four of fourteen patients (28%) developed moderate or severe neurotoxicity (grades 2 and 3 of the NCI-CTC), manifested as conus medullaris/cauda equine syndrome or pseudotumour cerebri-like syndrome, after a median of 3.5 IT courses of liposomal cytarabine. All patients had received corticosteroids to prevent arachnoiditis. Liposomal cytarabine given via the IT route, even with concomitant corticosteroid administration, can result in significant neurotoxicity in some patients. We discuss the potential pathogenesis of these effects and suggest hypothetical therapeutic measures to prevent these complications. Specialists should be aware of these possible complications when administering prophylactic IT liposomal cytarabine in high-grade NHL patients, and additional prospective studies should be conducted to more clearly delineate the frequency and characteristics of these complications.

    We have previously shown that Salmonella immunotherapy is effective to treat B-cell non-Hodgkin lymphoma (B-NHL) in mice. However, this model involves animals with high tumor burden, whereas in the clinics B-NHL patients are usually treated with chemotherapy (CHOP: cyclophosphamide, doxorubicin, vincristine, and prednisone) as first-line therapy prior to immunotherapy. Recently, we have described a NHL-B preclinical model using CHOP chemotherapy to achieve MRD in immunocompetent animals that closely resemble patients’ conditions. In this work, we assessed the efficacy of Salmonella immunotherapy in B-NHL-bearing mice undergoing chemotherapy. Salmonella administration significantly delayed tumor growth and prolonged survival of chemotherapy-treated NHL-bearing animals. Mice receiving the CHOP–Salmonella combined therapy showed increased numbers of tumor-infiltrating leukocytes and a different profile of cytokines and chemokines expressed in the tumor microenvironment. Further, Salmonella immunotherapy in CHOP-treated animals also enhanced NK cells cytotoxic activity as well as induced systemic lymphoma-specific humoral and cellular responses. Chemotherapy treatment profoundly impacted on the general health status of recipient animals, but those receiving Salmonella showed significantly better overall body condition. Altogether, the results clearly demonstrated that Salmonella immunotherapy could be safely used in individuals under CHOP treatment, resulting in a better prognosis. These results give strong support to consider Salmonella as a neoadjuvant therapy in a clinical setting. PMID:29410666

    The results of radiotherapy in early stage orbital non-Hodgkin's lymphoma are described. From 1970-1985, 33 orbital localizations in 30 patients were treated. Total dose applied ranged from 21-57 Gy (2 Gy/fraction), 2/3 off all patients received a 40 Gy dose. Complete response rate was 94% and 10 years actuarial survival was 90%; between patients with low grade or intermediate grade lymphoma no significant difference in survival was observed. No local recurrence was detected during follow up and 20% of the patients developed generalized disease. Two optic nerve neuropathies and 3 retinopathies were observed in 5 patients, 4 of these occurred at a dose level of less than 43 Gy. Keratitis occurred in 58% of the patients treated, a sicca syndrome in 30% and cataract of different grades in 58%. Although local control was excellent, severe complications were observed in 13% of the patients who received a dose of less than 43 Gy. (author). 35 refs., 4 figs., 5 tabs

    There is inconsistent evidence that increasing birth order may be associated with risk of non-Hodgkin lymphoma (NHL). The authors examined the association between birth order and related variables and NHL risk in a pooled analysis (1983-2005) of 13,535 cases and 16,427 controls from 18 case-control studies within the International Lymphoma Epidemiology Consortium (InterLymph). Overall, the authors found no significant association between increasing birth order and risk of NHL (P-trend = 0.082) and significant heterogeneity. However, a significant association was present for a number of B- and T-cell NHL subtypes. There was considerable variation in the study-specific risks which was partly explained by study design and participant characteristics. In particular, a significant positive association was present in population-based studies, which had lower response rates in cases and controls, but not in hospital-based studies. A significant positive association was present in higher-socioeconomic-status (SES) participants only. Results were very similar for the related variable of sibship size. The known correlation of high birth order with low SES suggests that selection bias related to SES may be responsible for the association between birth order and NHL.

    Sixty-four patients with stages I and II non-Hodgkin's lymphomas (NHL) involving Waldeyer's ring treated between 1970 and 1987 were reviewed. Patients with stage II NHL were subdivided into stage II1 (limited type) and stage II2 (advanced type) from the state of neck nodes. Stage II1 was defined as involvement of unilateral cervical nodes less than 4 cm in diameter as well as Waldeyer's ring involvement. Other stage II cases were classified as stage II2. All 17 patients with stage I HNL were treated with radiation therapy alone. Their diseases were well controlled, and none of them died of causes related to the lymphoma. Among 14 patients with stage II1 NHL, the 5-year survival rate for the 9 patients treated with radiation therapy alone was 87.5%. Until 1982, 19 of 21 patients with stage II2 NHL treated with radiation therapy alone or radiation therapy and adjuvant chemotherapy (VEMP or COPP) died within 5 years mainly of disseminated diseases. Since 1983, CHOP had been used as the main treatment as well as radiotherapy for the 12 stage II2 NHL patients. So far, only 3 of them relapsed and 2 of them died of causes related to the lymphoma. Only 1 of these 12 patients was T-cell lymphoma compared to 7 of 9 stage II2 patients before 1982. This suggests that patients with stage I and those with limited stage II can be safely treated with radiotherapy. Also aggressive chemotherapy as well as radiotherapy should be used for patients with advanced stage II HNL involving Waldeyer's ring. (author)

    Full Text Available The objective of this multicenter prospective study was to determine the clinical efficacy and toxicity of a polychemotherapeutic third generation regimen, VACOP-B, with or without radiotherapy as front-line therapy in aggressive localized non-Hodgkin's lymphoma. Ninety-three adult patients (47 males and 46 females, median age 45 years with aggressive localized non-Hodgkin's lymphoma, 43 in stage I and 50 in stage II (non-bulky, were included in the study. Stage I patients received VACOP-B for 6 weeks plus involved field radiotherapy and stage II patients received 12 weeks VACOP-B plus involved field radiotherapy on residual masses. Eighty-six (92.5% achieved complete remission and 4 (4.3% partial remission. Three patients (3.2% were primarily resistant. Ten-year probability of survival, progression-free survival and disease-free survival were 87.3, 79.9 and 83.9%, respectively. Eighty-four patients are surviving at a median observation time of 57 months (range: 6-126. Statistical analysis showed no difference between stages I and II in terms of response, ten-year probability of survival, progression-free survival or disease-free survival. Side effects and toxicity were negligible and were similar in the two patient groups. The results of this prospective study suggest that 6 weeks of VACOP-B treatment plus radiotherapy may be the therapy of choice in stage I aggressive non-Hodgkin's lymphoma. Twelve weeks of VACOP-B treatment with or without radiotherapy was shown to be effective and feasible for stage II. These observations need to be confirmed by a phase III study comparing first and third generation protocols in stage I-II aggressive non-Hodgkin's lymphoma.

    Full Text Available Lymphomas are solid tumors of immune system and Non-Hodgkin Lymphomas (NHL is the most prevalent lymphomas; with wide ranges of histological and clinical features, it is so difficult to identify them. Herein, various bioinformatics tools (such as gene differential expressions, epigenetics and protein analysis employed to find new treatment approach for NHL based on gene expression variation between classic Hodgkin and B NHL. Microarray libraries GSE20011 downloaded from NCBI database and analyzed with GEO2R software, then differential expression genes analyzed by four databases (DAVID, Wikipathways, BioCarta and KEGG databases. Kinase, transcription factor, microRNA analysis and protein-protein interaction network performed by X2K ,ChEA, microRNA TargetScan and Genes2Networks software respectively. Finally, drug target identified and carried out by Drug Pair Seeker and Connectivity MAP databases. The results showed GATA2 Transcription Factor (TF up-regulates genes while Sox2 down-regulates them.  Functional analysis of up-regulated genes showed highly activation in B cell receptor signaling pathway while programmed cell death and apoptosis program noted in down-regulated genes. Drug discovery facilities revealed that Verteporfin drug induces down-regulated genes while Prochlorperazine represses up-regulated genes. Three microRNA34a34c and miR-449 repressed up-regulated gene networks. The finding paves the roads toward B-NHL therapy with 34a/b and miR-449 microRNAs and Prochlorperazine / Verteporfin drugs.

    As in any medical disorder, in non-Hodgkin lymphomas (NHLs) also, precise analysis of causes of death is needed to focus research efforts and improve morbidity and mortality. The aim of this study was to review the clinical presentation, mode of death and the immunophenotype of the autopsy cases of NHL. Autopsy cases wherein NHL was diagnosed, were selected for study. Autopsy cases which were diagnosed as NHL, either antemortem or after autopsy during a 7 years period at a tertiary care referral centre were studied and reviewed. Descriptive statistical analysis used. The autopsy findings seen in eight cases of NHL were reviewed. Except one, all cases were above 40 years age. Infective etiology (62%) followed by cardiorespiratory failure (38%) was the cause of death observed in these patients. In three cases, the antemortem diagnosis of NHL was missed as the patients were being treated for acute febrile illness and were referred late to the Tertiary Care Centre. One of these was a case of extra-nodal primary splenic lymphoma. As NHL present with nonspecific symptoms, these tumours may not be detected in early stages and hence may not be treated appropriately. These patients have weakened immunity and hence are prone to infection and sepsis which can be a major cause of mortality. This autopsy study experience has shown that NHL can masquerade as acute febrile illness which if not detected early and treated adequately can turn fatal.

    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.

    Non-Hodgkin's lymphoma (NHL) remains the second most common malignant complication in patients with human immunodeficiency virus (HIV) infection. Even though NHL is commonly chemosensitive to primary treatment, failure or relapse still occurs in a large number of patients. We conducted this retrospective study to evaluate the efficacy and safety of gemcitabine, dexamethasone, and cisplatin (GDP) for relapsed or refractory AIDS-related NHL (AIDS-NHL). Forty-eight patients with relapsed or refractory AIDS-NHL were treated with intravenous combination chemotherapy with GDP. The overall objective response rate was 54.1% (95% confidence interval, CI, 40.1-68.3%), with 10 complete responses and 16 partial responses. The 2-year overall survival rate (OS) was 70.8% (95% CI 58.0-83.7%), and the 5-year OS was 41.7% (95% CI 27.7-55.6%). The 2-year progression-free survival rate (PFS) was 37.5% (95% CI 23.8-51.2%), and the 5-year PFS was 25.0% (95% CI 12.8-37.3%). The median progression-free survival was 8.8 months (95% CI 0-20.3 months), and the median overall survival was 40.6 months (95% CI 22.6-58.6 months). Patients with B cell tumors who relapsed but had no B symptoms were clinical stage I/II, had infiltration fewer than two extranodal sites, had CD4⁺ counts >200 cells/μL, and had lactate dehydrogenase (LDH) less than the upper limit of normal benefited from GDP. The level of LDH had a significant impact on the response rate to chemotherapy with GDP (P = 0.015). Myelosuppression was the main side effect; the incidence of grade 3-4 anemia was 8.3%; leukopenia, 37.5%; and thrombocytopenia, 48.3%. Univariate and multivariate analyses were performed to determine variables for OS and PFS. This study confirms that GDP is an effective and safe salvage regimen in relapsed or refractory AIDS-NHL, was associated with modest declines in CD4⁺ lymphocyte counts, and did not promote HIV-1 viral replication.

    A case-control study was performed to examine whether the observed excess of childhood leukaemia and non-Hodgkin's lymphoma in the area around the Dounreay nuclear installation is associated with established risk factors, or with factors related to the plant, or with parental occupation in the nuclear industry. No raised relative risks were found for prenatal exposure to X-rays, social class of parents, employment at Dounreay before conception or diagnosis, father's dose of ionising radiation before conception, or child's residence within 50 m of the path of microwave transmission beams. Results also proved negative for all lifestyle factors except an apparent association with use of beaches within 25 km of Dounreay. However, this result was based on small numbers, arose in the context of multiple hypothesis testing, and is certainly vulnerable to possible systematic bias. It was concluded that the raised incidence of childhood leukaemia and non-Hodgkin's lymphoma around Dounreay cannot be explained by paternal occupation at Dounreay or by paternal exposure to external ionising radiation before conception. The observation of an apparent association between the use of beaches around Dounreay and the development of childhood leukaemia and non-Hodgkin's lymphoma might be an artefact of multiple testing and influenced by recall bias.

    Full Text Available The rate of non-Hodgkin's lymphomas (NHL has increased around the world during the last decades. Apart from the role of the human immunodeficiency virus (HIV infection in the development of NHL, exposure to chemical agents like phenoxyacetic pesticides, hair dyes, metal fumes and organic solvents are suspected to be involved. The present review evaluates the results of studies that directly or indirectly searched for an association between solvent exposure and NHL. The selected studies comprised those published from 1979 to 1997, designed to investigate risk factors for NHL, whether specifically looking for solvent exposure or for general risks in which solvent exposure could be included. In 25 of the 45 reviewed studies (55.5%, fifty-four statistically significant associations between NHL and solvent exposure related occupations or industries were reported. Statistical significance was more frequently shown in studies where solvent exposure was more accurately defined. In eighteen of such studies, 13 (72.2% defined or suggested organic solvents as possible risk factors for NHL.

    Full Text Available Abstract 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.

    Full Text Available Monoclonal antibodies have been the most successful therapeutics ever brought to cancer treatment by immune technologies. The use of monoclonal antibodies in B-cell Non-Hodgkin's lymphomas (NHL represents the greatest example of these advances, as the introduction of the anti-CD20 antibody rituximab has had a dramatic impact on how we treat this group of diseases today. Despite this success, several questions about how to optimize the use of monoclonal antibodies in NHL remain open. The best administration schedules, as well as the optimal duration of rituximab treatment, have yet to be determined. A deeper knowledge of the mechanisms underlying resistance to rituximab is also necessary in order to improve the activity of this and of similar therapeutics. Finally, new antibodies and biological agents are entering the scene and their advantages over rituximab will have to be assessed. We will discuss these issues and present an overview of the most significant clinical studies with monoclonal antibodies for NHL treatment carried out to date.

    Full Text Available Non-Hodgkin's lymphoma (NHL is a lymphatic system tumor originating from either B or T lymphocytes and shows a high malignant potential. In HIV-seropositive patients, NHL of head and neck is mainly found in Waldeyer's ring, oral mucosa, salivary glands, paranasal sinuses, and laryngeal tissue. Primary NHL rarely affects the bone. When the lesion affects the bones of the jaws, it is rare in the mandible when compared to the maxilla. In the reported cases, only 0.6% are found in the mandible. NHL of the mandible can be difficult to diagnose, and so the prime aim of the present case report is to establish appropriate diagnosis of one of such kinds. Clinically, they may imitate a dental infection with symptoms of pain and discomfort. A delay in diagnosis may lead to a poor prognosis. Herewith, we present a case of NHL on the lower-right mandible in a 40-year-old male. A correlation of clinical findings, radiological examination, and histopathological examination enabled us in early diagnosis and differentiating it from other similar conditions, thus aiding in initiation of prompt treatment.

    Full Text Available The aim of this study was to investigate inequalities in survival for non-Hodgkin's lymphoma (NHL, distinguishing between direct and indirect effects of patient, social and process-of-care factors.All cases of NHL diagnosed in Ireland in 2004-2008 were included. Variables describing patient, cancer, stage and process of care were included in a discrete-time model of survival using Structural Equation Modelling software.Emergency admissions were more common in patients with co-morbid conditions or with more aggressive cancers, and less frequent for patients from more affluent areas. Aggressive morphology, female sex, emergency admission, increasing age, comorbidity, treatment in a high caseload hospital and late stage were associated with increased hazard of mortality. Private patients had a reduced hazard of mortality, mediated by systemic therapy, admission to high caseload hospitals and fewer emergency admissions.The higher rate of emergency presentation, and consequent poorer survival, of uninsured patients, suggests they face barriers to early presentation. Social, educational and cultural factors may also discourage disadvantaged patients from consulting with early symptoms of NHL. Non-insured patients, who present later and have more emergency admissions would benefit from better access to diagnostic services. Older patients remain disadvantaged by sub-optimal treatment, treatment in non-specialist centres and emergency admission.

    Non-Hodgkin lymphoma (NHL) incidence rates have increased considerably in New Zealand. Methods. Incidence and mortality rates for NHL from 1981 to 2010 were calculated. Trends in age-specific rates were analysed and age-period-cohort models fitted to explore generation-specific changes in incidence and mortality. Results. NHL incidence increased by 67% for men and 74% for women between the 1981-1985 and 2006-2010 time periods in New Zealand. For women born about 1936 and men born about 1946, NHL incidence and mortality have diverged suggesting an improved prognosis for recent generations. Conclusion. The strong generation effects suggest that an exposure before 25 years of age is of major importance in determining the lifetime risk of NHL in New Zealand. NHL incidence rates in New Zealand will continue to increase in the future and probably more in females than males, as generations with increased risk age. Current hypotheses for the cause of NHL do not explain the trends observed. A decline in the prevalence of a protective factor may have also contributed to these trends. Examination of trends for subtypes of NHL and innovative testable hypotheses that may explain these trends are needed.

    Reports of leukemia and non-Hodgkin lymphoma (NHL), cancers known to have a similar pathophysiology, among workers in the semiconductor industry have generated much public concern in Korea. This paper describes cases reported to the NGO Supporters for the Health and Rights of People in the Semiconductor Industry (SHARPs). We identified demographic characteristics, occupational, and disease history, for 17 leukemia and NHL cases from the Giheung Samsung semiconductor plant, diagnosed from November 2007 to January 2011. Patients were relatively young (mean = 28·5 years, SD = 6·5) at the time of diagnosis and the mean latency period was 104·3 months (SD = 65·8). Majority of the cases were fabrication operators (11 workers among 17) and 12 were hired before 2000. Six cases worked in the etching or diffusion process. The evidence to confirm the causal relationship between exposures in the semiconductor industry and leukemia or NHL remains insufficient and a more formal, independent study of the exposure-disease relationship in this occupation is needed. However, workers should be protected from the potential exposures immediately.

Corresponding hazard ratios after childhood leukemia were 10.4 (95% CI, 0.4-223) for thyroid cancer, 7.2 (95% CI, 2.0-26) for brain cancer, and 6.5 (95% CI, 0.4-110) for NHL. Patients with adult leukemia have excess risk of thyroid cancer, brain cancer......Patients with childhood leukemia surviving into adulthood have elevated risk of developing thyroid cancer, brain cancer, and non-Hodgkin lymphoma (NHL); these risks cannot automatically be extrapolated to patients surviving adult leukemia. We tested whether survivors of adult leukemia...... are at increased risk of developing thyroid cancer, brain cancer, and NHL. We included the entire adult Danish population (14 years of age or older), in a 28-year follow-up period from 1980 through 2007, composed of 6 542 639 persons; during this period, 18 834 developed adult leukemia, 4561 developed thyroid...

    The present study was undertaken to evaluate the frequency, characteristics and actual risk of secondary acute non lymphoid leukemia (s-ANLL) in 141 patients treated for non Hodgkin's lymphoma with different modalities. One hundred and twenty-four patients received chemotherapy according to PROVECIP protocol (9). Of these, 15 also received as induction treatment a local nodal irradiation and 33 an extended field radiotherapy. Seventeen out of 141 were treated by total body irradiation. Of these, 15 relapsed and received salvage chemotherapy. Sixteen of the 124 patients trated with PROVECIP also underwent different chemotherapeutic programs as salvage treatment. Of the entire population studied, 2 patients significantly affected the occurrence of s-ANLL, since both leukemias occurred in patients treated with total body irradiation, given alone or followed by chemotherapy. The actuarial risk at 8 years was 5.24% in the whole group, whereas it greatly increased in the group of patients treated with total body irradiation (24%). Conversely, no risk was found in the group treated with PROVECIP, alone, with additional chemotherapy, or with associated local or extended field radiotherapy

    Yttrium is one of the most useful radionuclides for radioimmunotherapeutic applications, especially labelling with monoclonal antibodies. Rituximab was bound to the DTPA chelating agent using Hnatowich methods. Cyclic anhydride DTPA (cDTPAa, 0.1 mg/ml) was dissolved in chloroform and was degassed under a stream of nitrogen for 30 minutes. Rituximab solution in 0.05 M bicarbonate buffer was immediately added and mixed for one minute at room temperature. The antibody Rituximab at different concentration (5 mg/ml and 10 mg/ml) was coupled with the cDTPAa, at molar ratios (cDTPAa : Rituximab) of 1:1, 3:1, 5:1, 10:1 and 20:1. The conjugation of DTPA-Rituximab mixture was labelled with Y-90, then using Sephadex G25 in order to determine coupling efficiency. Coupling efficiency at a 3:1 mole ratio was 70%. After purification, the conjugation DTPA-Rituximab was labeled with Y-90 in 0.5 M acetate buffer, pH 5, at room temperature. The labeling yield was about 99%. The radiochemical purity of 90 Y-DTPA-Rituximab was more than 98 % which determined by ITLC in 0.1 M acetate at pH 6 as mobile phase. The radiopharmaceuticals have been test for sterility, apyrogenicity and biodistribution. This is a potential radiopharmaceutical for clinical application in therapeutic Non Hodgkin Lymphoma treatments. (author)

    Occupational exposure to solvents has been reported to increase non-Hodgkin lymphoma (NHL) risk in some, but not all, studies. In a population-based case-control study, we examined whether participation in selected hobbies involving solvent exposure increases NHL risk. We identified NHL cases diagnosed at ages 20-74 years between 1998 and 2000 in Iowa or metropolitan Los Angeles, Detroit, and Seattle. Controls were selected using random digit dialing or Medicare files. Computer-assisted personal interviews (551 cases, 462 controls) elicited data on model building, painting/silkscreening/artwork, furniture refinishing, and woodworking/home carpentry. Hobby participation (68% of cases, 69% of controls) was not associated with NHL risk (OR = 0.9, 95% CI = 0.7-1.2). Compared to people with none of the hobbies evaluated, those who built models had significantly lower risk (OR = 0.7, CI = 0.5-1.0), but risk did not vary with the number of years or lifetime hours. Risk estimates for the other hobbies were generally less than one, but the associations were not significant and there were no notable patterns with duration of exposure. Use of oil-based, acrylic, or water-based paints; paint strippers; polyurethane; or varnishes was not associated with NHL risk. We conclude that participation in hobbies involving exposure to organic solvents is unlikely to increase NHL risk.

    Full Text Available Abstract Background We evaluated if the survival benefit of adding rituximab to standard chemotherapy for non-Hodgkin lymphoma (NHL observed in clinical trials has been experienced by an Australian NHL patient population. Methods NHL cases diagnosed in 1985-2004 in New South Wales (NSW were followed-up to the end of 2004. Rituximab prescription data were obtained from Medicare Australia. Using a Poisson regression model adjusted for age group, sex, NHL subtype and time period (1990-1994, 1995-1999 and 2000-2004, we estimated excess risk of death after a diagnosis of NHL. To give context to the survival trend, trends in incidence and mortality were also estimated. Results Compared with 1990-1994, after adjusting for age, sex and NHL subtype the relative excess risk of death was significantly lower (p Conclusion It is likely that some benefit of adding rituximab to the standard chemotherapy for NHL has been experienced at the population level.

    We report a population based case-control study of exposure to pesticides as risk factor for non-Hodgkin lymphoma (NHL). Male and female subjects aged 18-74 years living in Sweden were included during December 1, 1999, to April 30, 2002. Controls were selected from the national population registry. Exposure to different agents was assessed by questionnaire. In total 910 (91 %) cases and 1016 (92%) controls participated. Exposure to herbicides gave odds ratio (OR) 1.72, 95% confidence interval (CI) 1.18-2.51. Regarding phenoxyacetic acids highest risk was calculated for MCPA; OR 2.81, 95% CI 1.27-6.22, all these cases had a latency period >10 years. Exposure to glyphosate gave OR 2.02, 95% CI 1.10-3.71 and with >10 years latency period OR 2.26, 95% CI 1.16-4.40. Insecticides overall gave OR 1.28, 95% CI 0.96-1.72 and impregnating agents OR 1.57, 95% CI 1.07-2.30. Results are also presented for different entities of NHL. In conclusion our study confirmed an association between exposure to phenoxyacetic acids and NHL and the association with glyphosate was considerably strengthened.

    An increased rate of non-Hodgkin's lymphoma (NHL) has been repeatedly observed among farmers, but identification of specific exposures that explain this observation has proven difficult. During the 1980s, the National Cancer Institute conducted three case-control studies of NHL in the midwestern United States. These pooled data were used to examine pesticide exposures in farming as risk factors for NHL in men. The large sample size (n = 3417) allowed analysis of 47 pesticides simultaneously, controlling for potential confounding by other pesticides in the model, and adjusting the estimates based on a prespecified variance to make them more stable. Reported use of several individual pesticides was associated with increased NHL incidence, including organophosphate insecticides coumaphos, diazinon, and fonofos, insecticides chlordane, dieldrin, and copper acetoarsenite, and herbicides atrazine, glyphosate, and sodium chlorate. A subanalysis of these "potentially carcinogenic" pesticides suggested a positive trend of risk with exposure to increasing numbers. Consideration of multiple exposures is important in accurately estimating specific effects and in evaluating realistic exposure scenarios.

    Full Text Available We report a case of multiple autoimmunity consisting of the presence of autoimmune haemolytic anaemia (AIHA, antimitochondrial antibodies (AMAs, and antiphospholipid antibodies (APLAbs as the presenting manifestations of an extrahepatic B-non-Hodgkin lymphoma (B-NHL in a 63-year-old woman. The patient presented with fatigue attributed to severe AIHA. Due to increased serum IgM and -GT levels, an investigation for AMA was performed, which proved positive with anti-M2 specificity. A prolongation of activated partial thromboplastin time (aPTT led to the determination of APLAbs (lupus anticoagulant and other APLAbs which were also positive. Bone marrow biopsy in combination with immmunohistochemical studies established the diagnosis of lymphoplasmacytic B-NHL. Ten months later, B-NHL was in remission while AMA and APLAbs were still positive. In conclusion, we documented the coexistence of multiple autoimmune reactions together with B-NHL highlighting the possible common pathogenetic pathways of the two entities.

    Malignant pleural effusion (MPE) appears in up to 20% of patients with non-Hodgkin's lymphoma (NHL). The present study aimed to assess the efficacy of medical thoracoscopy (MT) in the diagnosis of patients with MPE induced by NHL. Between July 2005 and June 2014, 833 patients with pleural effusions of unknown etiology underwent MT in Beijing Chaoyang Hospital (Beijing, China), where diagnostic thoracocentesis or/and blind pleural biopsy had failed to yield an answer. Demographic, radiographic, thoracoscopic, histological and immunophenotyping data of 10 NHL patients with MPE were then retrospectively analyzed. Under medical thoracoscopy, pleural nodules (in n=6 patients), hyperemia (n=5), plaque-like lesions (n=4), pleural thickening (n=3), cellulose (n=3), ulcer (n=2), adhesion (n=2), and scattered hemorrhagic spots (n=1) were observed on the surface of parietal pleura. Histopathological and immunohistochemical analysis of pleural biopsy samples led to a correct diagnosis of B-cell NHL in 7 patients and T-lymphoblastic NHL in 2 patients. Data from the present study demonstrated that pleural biopsy through MT achieved a definite diagnosis of NHL in 9 out of 10 (90%) patients with MPE induced by NHL. Therefore, MT is a useful method for diagnosing MPE induced by NHL.

    The use of rituximab (RTX) is increasing, even in developing countries. It has become the first-line therapy or adjuvant to chemotherapy (CHOP; cyclophosphamide, hydroxydaunorubicin, oncovin and prednisone) for various diseases, including B cell lymphoma and autoimmune diseases. We describe the infectious diseases and immunological markers associated with RTX treatment of patients with non-Hodgkin lymphoma (NHL). Serum immunoglobulins were determined before and after intravenous immunoglobulin (IVIg) administration. Pneumo-23IgG-specific anti-pneumococcal antibodies were evaluated before and after vaccination. Immunophenotyping and lymphocyte proliferation were determined in the course of the treatment. Seven patients were followed and median age was 56.0 ± 5.0 years (range, 41.9-71.6 years). At baseline, the mean level of IgG was 333.7 ± 40.8 and IgM 40.9 ± 11.3 mg/dL, respectively; immunoglobulin A and E (IgA and IgE) were under the limit of detection. Two patients had reduced or absent B cells and T cell subsets were at normal levels in five patients. All patients failed to mount an efficient post-vaccination immune response against hepatitis B virus, tetanus, diphtheria and against the 23-valent pneumococcal polysaccharide vaccine. During RTX/CHOP treatment, human-IgG-immunoglobulin (IVIg) therapy was introduced in six patients after recurrent infections, including community-acquired pneumonia (85.7%), chronic sinusitis (85.7%) and gastroenteritis (42.9%). Poor response against pneumococcal vaccines increases the susceptibility of respiratory diseases in these patients. In patients with NHL treated with RTX, the benefits achieved with IVIg replacement for the control of recurrent infectious diseases is of paramount importance. Clinicians dealing with monoclonal antibodies against cancer therapy, especially RTX, should be aware of the increasing risks for symptomatic induced hypogammaglobulinemia and respiratory infections.

    Full Text Available 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

At close contact of inoculated baboons with healthy non-inoculated animals, the lymphoma spread between them. The epidemiological analysis, postmortem examination, histological analysis, tissue culturing, and PCR were used for the diagnostics of lymphoma and pre-lymphoma, purification, identification of STLV-1, and HVP viruses. Characteristic clinical and morphological signs designated by us as pre-lymphoma often precede the lymphoma development. In some cases, pre-lymphoma does not develop in lymphoma because animals die from various diseases and do not reach the point of the lymphoma development.

    A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately. This synthesis of the literature on radiation therapy for non-Hodgkin's lymphoma [G1] (NHL) is based on data from seven randomized trials. Moreover, data from 17 prospective studies, 22 retrospective studies and 27 other articles were used. In total, 73 scientific articles are included, involving 13,305 patients. The results were compared with those of a similar overview from 1996 including 14,137 patients. The conclusions reached can be summarized as follows: Indolent lymphomas: Data indicate that one-third to one-half of patients with indolent lymphoma in stage I are cured by radiotherapy (follow-up more than 15 years). Addition of chemotherapy to radiotherapy does not indicate any improvement in overall outcome. Optimal radiation dose is not defined and extended field is not superior to involved field. Aggressive localized lymphomas: Data indicate that half of the patients in stage I are cured by radiotherapy alone. Although randomized and non-randomized studies favour combined modality treatment with chemotherapy followed by radiotherapy instead of radiotherapy or chemotherapy alone in localized disease, no firm conclusions can be drawn. Conflicting data have been published on the value of radiotherapy towards bulky disease and no firm conclusions can be drawn. Optimal dose for radiation alone or after chemotherapy has not been established. Total body irradiation (TBI) The value of TBI for treatment of NHL has not been proven. There is no proof that fractionated TBI in conjunction with high-dose chemotherapy is superior to chemotherapy regimens alone. Primary CNS lymphomas Data show that radiotherapy induces a response of short duration and is associated with major neurotoxicity, especially in elderly patients. High

    After first-line therapy, patients with Hodgkin and aggressive non-Hodgkin lymphomas are followed closely for early signs of relapse. The current follow-up practice with frequent use of surveillance imaging is highly controversial and warrants a critical evaluation. Therefore a retrospective...... multicenter study of relapsed Hodgkin and aggressive non-Hodgkin lymphomas (nodal T-cell and diffuse large B-cell lymphomas) was conducted. All included patients had been diagnosed during the period 2002-2011 and relapsed after achieving complete remission on first-line therapy. Characteristics and outcome...... of imaging-detected relapses were compared to other relapses. A total of 258 patients with recurrent lymphoma were included in the study. Relapse investigations were initiated outside preplanned visits in 52% of the patients. Relapse detection could be attributed to patient-reported symptoms alone...

    Epstein-Barr virus (EBV) has been linked to malignancies and chronic inflammatory conditions. In this study, EBV detection was compared in children with non-Hodgkin's lymphoma and children with chronic inflammatory conditions, using samples and data from a case-control study carried out at the Mulago National Referral Hospital between 2004 and 2008. EBV viral load was measured in saliva, whole blood and white blood cells by real-time PCR. Serological values for IgG-VCA, EBNA1, and EAd-IgG were compared in non-Hodgkin's lymphoma and chronic inflammatory conditions; and in Burkitt's lymphoma and other subtypes of non-Hodgkin's lymphoma. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated. Of the 127 children included (87 males and 40 females; median age 7 years, range 2-17), 96 had non-Hodgkin's lymphoma (46 Burkitt's lymphoma and 50 other non-Hodgkin's lymphoma), 31 had chronic inflammatory conditions, and only 10% were HIV-positive. The most common clinical presentations for all disease categories considered were fever, night sweats, and weight loss. EBV viral load in whole blood was elevated in Burkitt's lymphoma compared to other non-Hodgkin's lymphoma (OR 6.67, 95% CI 1.32, 33.69; P-value = 0.04), but EBV viral loads in saliva and white blood cells were not different in any of the disease categories considered. A significant difference in EAd-IgG was observed when non-Hodgkin's lymphoma was compared with chronic inflammatory conditions (OR 0.19, 95% CI 0.07, 0.51; P-value = 0.001). When compared to chronic inflammatory conditions, EBV viral load was elevated in Burkitt's lymphoma, and EA IgG was higher in non-Hodgkin's lymphoma. This study supports an association between virological and serological markers of EBV and childhood non-Hodgkin's lymphoma, irrespective of subtype, in Uganda. © 2014 Wiley Periodicals, Inc.

    We previously reported a positive association among body mass index, single nucleotide polymorphisms (SNP) in the leptin and leptin receptor genes that are involved in body weight regulation, and non-Hodgkin lymphoma (NHL). Polymorphisms in the ghrelin (GHRL) and neuropeptide Y (NPY) genes were examined in the same population-based case-control study of NHL to further explore the role of genes involved in energy homeostasis and obesity in susceptibility to NHL. Ghrelin is an orexigenic hormone that induces NPY release and inhibits proinflammatory cytokines via its antagonistic relationship with leptin. NPY is a potent appetite stimulator controlled by ghrelin and leptin and also acts as a mediator of immune function. DNA from 458 cases and 812 controls was genotyped. Among genotyped GHRL SNPs, the variant allele for GHRL -4427G>A was inversely associated with all NHL [odds ratios (OR), 0.78; 95% confidence interval (95% CI), 0.59-1.0] and more specifically with diffuse large cell lymphoma (DLCL; homozygous variant: OR, 0.31; 95% CI, 0.13-0.74). Another SNP, GHRL 5179A>G, decreased the risk of DLCL (homozygous variant: OR, 0.35; 95% CI, 0.10-1.2). NPY -485T>C, 1258G>A, and 5671C>T were in total linkage disequilibrium (D' = 0.99) and the homozygous variants were associated with an increased risk of NHL in NPY SNPs -485T>C (OR, 1.7; 95% CI, 1.1-2.5), 1258G>A (OR, 1.7; 95% CI, 1.1-2.5), and 5671C>T (OR, 1.9; 95% CI, 1.3-2.8). When stratified by subtype, the variant allele for NPY 1128T>C was positively associated with follicular lymphoma (OR, 2.3; 95% CI, 1.1-4.9) as were homozygous variants for NPY SNPs -485T>C (OR, 2.4; 95% CI, 1.3-4.4), 1258G>A (OR, 2.0; 95% CI, 1.1-3.5), and 5671C>T (OR, 1.8; 95% CI, 1.1-3.0). These results add further support for the hypothesis that SNPs in energy-regulating genes affect risk of NHL.

    Compromised immunity and chronic inflammation are thought to contribute to the development of non-Hodgkin lymphoma (NHL). Because tocopherols protect cells through antioxidant mechanisms, they may play a role in NHL etiology. This nested case-control study within the Multiethnic Cohort examined the association of prediagnostic serum tocopherols levels measured in 271 NHL cases and 538 matched controls by high-pressure liquid chromatography/photodiode array detection with NHL risk. Conditional logistic regression was used to calculate ORs and 95% confidence intervals (CI). We observed U-shaped associations with NHL for total and α-tocopherols [Ptrend tocopherols, which consisted primarily of α-tocopherol, were 0.41 (0.25-0.68), 0.52 (0.32-0.85), 0.39 (0.23-0.65), and 0.78 (0.47-1.29) for the second to fifth quintiles as compared with the first. The risk estimates were similar for α-tocopherol but nonsignificant for β- and γ-tocopherol combined and for γ-tocopherol. Adjustment for serum lipids strengthened the nonlinear associations for total and α-tocopherols. Serum total tocopherol levels were higher for vitamin E supplement users at cohort entry than nonusers (21.32 ± 9.04 vs. 17.72 ± 7.43 μg/mL; P tocopherols, at levels likely reflecting adequate dietary intakes, may be protective against NHL, whereas higher intakes from supplementation may not be beneficial. The association between serum tocopherol levels and NHL risk provides possible new insights into the etiology of NHL. ©2013 AACR.

    A large body of evidence suggests that being diagnosed with and treated for cancer adversely affects functioning and quality of life, yet less is known about longer term outcomes. Therefore, this study aims to estimate the prevalence of post-traumatic stress disorder (PTSD) symptoms in survivors of adult non-Hodgkin's lymphoma (NHL) who are at least 2 years postdiagnosis and identify the risk factors associated with PTSD symptoms, with a focus on those that are amenable for screening and modifiable. A total of 886 NHL survivors identified from the cancer registries of two hospitals in North Carolina participated, ranging in age from 25 to 92 years old and ranging from 2 to 44 years postdiagnosis. Survivors were mailed a survey that assessed PTSD symptoms and quality of life. Participants averaged 10.2 years postdiagnosis, and most (61%) reported no PTSD symptoms. The adjusted prevalence for full PTSD was 7.9%, with an additional 9.1% meeting criteria for partial PTSD. Modifiable risk factors that were independently associated with PTSD in multiple linear regression included less social support, negative appraisals of life threat and treatment intensity, and more employment and insurance issues. Additionally, several demographic characteristics (nonwhite race, less education, and younger age) and clinical or health-related factors (active disease, more recent diagnosis, and more comorbidity) were independently associated with PTSD. Although only 8% of survivors met PTSD diagnostic criteria, the impact of a cancer diagnosis and treatment persists for many survivors, as evidenced in 39% of this sample. Early identification of those at risk could enable treatment to minimize PTSD symptomatology.

    In the present study, the serum levels of some cytokines and the matrix metalloproteinase-9 (MMP-9) were studied in an attempt to find suitable markers for early diagnosis of non- Hodgkin's lymphoma (NHL) and to assess their role in differentiating between disseminated and non disseminated cases. The present study was conducted on 60 patients with non disseminated NHL, 14 patients with disseminated NHL, in addition to 10 healthy controls. Their sera were used to determine tumor necrosis factor-α (TNF--α), tumor necrosis factor--β (TNF-β), interferon---α), (IFN--α), interferon-γ (IFN--γ) and Matrix Metalloproteinase-9 (MMP-9) using the ELISA technique. The results showed that the serum level of TNF---α), and IFN---α), can be used to differentiate between the control group and the group of NHL patients. However, they could not differentiate between non disseminated NHL (nd- NHL) and disseminated NHL (d- NHL). On the other hand, the serum level of TNF-β) can be used to differentiate between nd- NHL and d- NHL, but not between the control group and nd-NHL. Each of [FN--γ and MMP-9 were not useful in discrimination between the control group and the diseased ones. Our data revealed no correlation between serum level of the parameters investigated and the gender of the patients. The present results revealed that TNF-α) and INF-α), can be used as diagnostic tools for NHL. On the other hand, TNF-β) is useful in the differentiation between nd-NHL and d-NHL

    Objective: To evaluate the effects of nasal non-Hodgkin's lymphoma(N-NHL) treated with chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and autologous peripheral blood stem cell transplantation(APBSCT) combined with total body irradiation(TBI); and to analyze the impact factors of prognosis. Methods: 135 patients were treated between 1980 and 2000. All were confirmed by histopathology as N- NHL, including 122 T cell in origin, 12 B cell and 1 NK cell in origin. The main radiotherapy portal was set in front of the nose with a spade-like protrusion, supplement with a portal next to the ear on one side or both sides. Combined portal in facial cervical area was first used when there was invasion of the oropharynx. The median dose to the nasal cavity was 56.0 Gy with a range of 35.2 to 75.5 Gy, with added 30 Gy to the primary lesion in two patients. Six patients received TBI combined with APBSCT, with 8 Gy in the TBI group. Chemotherapy, given before or during after radiotherapy or alone, consisted of 2-6 cycles of COP, COPP, COMP, CHOP or COBDP. Prognostic factors were analyzed with Cox model. Results: The local control rate was 12%, 69%, 76% and 83% in chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and APBSCT combined with TBI, respectively (P=0.057). The 5-year survival rate was 9%, 52%, 63% and 83%, respectively (P=0.032). Multi- factor analysis showed that tumor extension and treatment methods were the most important prognostic factors be- sides Ann-Arbor stage, but gender, pathology, age and symptoms had little effect on prognosis. Conclusions: Chemotherapy plus radiotherapy group achieves a better survival rate than radiotherapy alone. It is helpful to evaluate prognosis to make more detail subareas on basis of local extensions in Ann Arbor staging system. For some N- NHL patients with good financial condition, APBSCT combined with TBI is a good choice. (authors)

    2006-01-01

    Purpose: To report the tolerability and efficacy of twice-daily whole-abdomen irradiation (WAI) for non-Hodgkin's lymphoma (NHL). Methods and Materials: Of 123 patients treated for NHL with WAI, 37% received previous chemotherapy, 28% received WAI as part of comprehensive lymphatic irradiation (CLI), and 32% received WAI for palliation. The median dose to the whole abdomen was 25.0 Gy, followed by a median tumor boost of 9.8 Gy in 58 patients. Fractionation was 1.0 Gy once daily (54%) or 0.8 Gy twice daily (46%). Blood counts were measured weekly. Results: At a median follow-up of 4.3 years, local control was 72% and overall survival was 55% at 5 years. Median time of WAI was 42 days for once-daily treatment and 32 days for twice-daily treatment. Patients receiving twice-daily WAI did not have a significantly higher rate of acute side effects (e.g., nausea, diarrhea, platelet or red blood cell toxicity). Overall, acute thrombocytopenia was the most frequent side effect of treatment; 24 of 96 patients (25%) with available hematologic data had Grade 3+ toxicity. There was no acute Grade 3 gastrointestinal toxicity and no late small bowel obstruction. Multiple regression indicated that patients with four or less involved sites and disease size ≤6 cm had improved local control and overall survival. Conclusions: Twice-daily WAI using 0.8 Gy/fraction does not appear to have any greater toxicity compared with once-daily treatment using 1 Gy/fraction. Small doses per fraction (0.8-1 Gy/fx) are effective, tolerated well in the acute setting, and associated with a low rate of late toxicity

    Full Text Available Abstract Background Non-Hodgkin's lymphomas (NHLs have been linked to proximity to industrial areas, but evidence regarding the health risk posed by residence near pollutant industries is very limited. The European Pollutant Emission Register (EPER is a public register that furnishes valuable information on industries that release pollutants to air and water, along with their geographical location. This study sought to explore the relationship between NHL mortality in small areas in Spain and environmental exposure to pollutant emissions from EPER-registered industries, using three Poisson-regression-based mathematical models. Methods Observed cases were drawn from mortality registries in Spain for the period 1994–2003. Industries were grouped into the following sectors: energy; metal; mineral; organic chemicals; waste; paper; food; and use of solvents. Populations having an industry within a radius of 1, 1.5, or 2 kilometres from the municipal centroid were deemed to be exposed. Municipalities outside those radii were considered as reference populations. The relative risks (RRs associated with proximity to pollutant industries were estimated using the following methods: Poisson Regression; mixed Poisson model with random provincial effect; and spatial autoregressive modelling (BYM model. Results Only proximity of paper industries to population centres (>2 km could be associated with a greater risk of NHL mortality (mixed model: RR:1.24, 95% CI:1.09–1.42; BYM model: RR:1.21, 95% CI:1.01–1.45; Poisson model: RR:1.16, 95% CI:1.06–1.27. Spatial models yielded higher estimates. Conclusion The reported association between exposure to air pollution from the paper, pulp and board industry and NHL mortality is independent of the model used. Inclusion of spatial random effects terms in the risk estimate improves the study of associations between environmental exposures and mortality. The EPER could be of great utility when studying the effects of

    The relationship between melanoma and chronic lymphocytic leukemia (CLL) or non-Hodgkin lymphoma (NHL) has been minimally investigated. The objective of this study was to examine the incidence of melanoma in patients with a history of CLL or NHL, and their associated mortality. Cohorts of Kaiser Permanente Southern California members with a history of CLL and NHL were identified. Age-adjusted incidence density rates of melanoma among patients with CLL or NHL were compared with rates of melanoma among the general population of Kaiser Permanente Southern California patients. The mortality of patients with melanoma was examined using Cox proportional hazards modeling. The age-adjusted incidence rate per 100,000 person-years for melanoma among patients with either CLL or NHL was 107 (95% confidence interval 84.4-129.6) versus 25.9 among the general population (95% confidence interval 84.4-129.6, P < .001). Patients with melanoma and a history of CLL or NHL had 2.46 greater odds of death compared with those without CLL or NHL (95% confidence interval 1.77-3.41). This study was retrospective in nature; the International Classification of Diseases, Ninth Revision codes used may contain diagnostic errors; and only overall survival was used in our analysis. Patients with a history of CLL or NHL have a higher incidence of melanoma. Patients with CLL or NHL who are subsequently given the diagnosis of melanoma have a higher mortality than patients with melanoma without a preceding diagnosis of CLL.

    The possibility of using [{sup 18}F] FDG PET for assessment of tumor extension in primary gastric non-Hodgkin`s lymphoma (NHL) was studied in 8 patients (6 high-grade and 2 low-grade, one of the MALT type) and in a control group of 7 patients (5 patients with NHL without clinical signs of gastric involvement, 1 patient with NHL and benign gastric ulcer and 1 patient with adenocarcinoma of the stomach). All patients with gastric NHL and the two with benign gastric ulcer and adenocarcinoma, respectively, underwent endoscopy including multiple biopsies for histopathological diagnosis. All patients with high-grade and one of the two with low-grade NHL and the patient with adenocarcinoma displayed high gastric uptake of [{sup 18}F] FDG corresponding to the pathological findings at endoscopy and/or CT. No pathological tracer uptake was seen in the patient with low-grade gastric NHL of the MALT type. In 6/8 patients with gastric NHL, [{sup 18}F] FDG PET demonstrated larger tumor extension in the stomach than was found at endoscopy, and there was high tracer uptake in the stomach in two patients who were evaluated as normal on CT. [{sup 18}F] FDG PET correctly excluded gastric NHL in the patient with a benign gastric ulcer and in the patients with NHL without clinical signs of gastric involvement. Although the experience is as yet limited, [{sup 18}F] FDG PET affords a novel possibility for evaluation of gastric NHL and would seem valuable as a complement to endoscopy and CT in selected patients, where the technique can yield additional information decisive for the choice of therapy.

    We have discussed a unique presentation of primary diffuse large cell B-cell non-Hodgkin (DLBC NHL) hepatic lymphoma involving the porta hepatis and biliary confluence causing obstructive jaundice with contiguous soft tissue involvement of the right lobe of liver extending up to the right renal cortex. This appears to be the only case in literature where primary hepatic lymphoma has shown contiguous localized intra- and extrahepatic tumor infiltration. A 67-year-old gentleman presented with history of significant loss of appetite and weight in 2 months with associated progressive painless cholestatic jaundice. Physical evaluation revealed normal vitals with pallor, deep icterus, scratch marks over the abdomen, generalized muscle wasting, grade II clubbing and a palpable non-tender liver with a globular, firm mass beneath the liver. He had a total serum bilirubin of 15.9 mg/dL and direct bilirubin of 9.24 mg/dL. His liver enzymes were moderately elevated with raised serum creatinine and dyselectrolytemia. Serology for enterohepatic viruses was negative. Contrast-enhanced magnetic resonance imaging (CEMRI) showed poorly enhancing multiple soft tissue masses in both lobes of liver with the largest mass involving, biliary confluence and porta hepatis causing right bile duct and portal vein encasement. The mass occupied the posterior right lobe and extended to the inferior surface of liver with contiguous invasion of the right renal upper pole cortex. The mass was associated with a retracted liver capsule in the involved segments and delayed enhancement, mimicking a cholangiocarcinoma. Tissue biopsy revealed hepatic DLBC type NHL and patient was subsequently treated with a CHOP-R (cyclophosphamide-doxorubicin-vincristine-prednisolone/rituximab) regimen, on which he has shown non-progressive disease at 1-year follow-up. DLBC NHL of the liver is a very rare tumor with propensity for isolated involvement of the liver and minimal extrahepatic spread. This case shows many

    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.

    In 2008, non-Hodgkin lymphoma ranked tenth among other malignancies worldwide with an incidence of around 5 cases per 100,000 in both genders. The latest available rates in Tunisia are from 2006. This study aimed to provide an update about NHL incidence for 2009 and its trend between 1998 and 2009 as well as a projection until 2024, using data from the Salah Azaiz Institute hospital registry and the Noth Tunisia cancer registry. In 2009, the NHL incidence in the north of Tunisia was 4.03 cases per 100,000, 4.97 for men and 3.10 for women. Diffuse large B-cell lymphoma (DLBCL) accounted for 63.2% of all NHL subtypes. Between 1998 and 2009, the overall trend showed no significant change. When we compared the trend between two periods (1998-2005 and 2005-2009), joinpoint regression showed a significant decrease of NHL incidence in the first period with an annual percentage change (APC) of -6.7% (95% CI:[-11.2%;-2%]), then the incidence significantly increased from 2005 to 2009 with an APC of 30.5% (95% CI: [16.1%; 46.6%]. The analyses of the different subtype trends showed a significant decrease in DLBCL incidence between 1998 and 2000 (APC:-21.5; 95% CI: [-31.4%;-10.2%]) then the incidence significantly increased between 2004 and 2007 (APC: 18.5; 95% CI: [3,6%;35.5%]). Joint point analysis of the age-period-cohort model projection showed a significant increase between 2002 and 2024 with an APC of 4.5% (%95 CI: [1.5%; 7.5%]). The estimated ASR for 2024 was 4.55/100 000 (95% CI: [3.37; 6.15]). This study revealed an overall steady trend in the incidence of NHL in northern Tunisia between 1998 and 2009. Projection showed an increase in the incidence in NHL in both genders which draw the attention to the national and worldwide burden of this malignancy.

    Objective: To study the CT manifestations of abdominal and pelvic lymph nodes in non- Hodgkin lymphoma (NHL) of Chinese patients, and to investigate their correlation with pathology subtypes. Methods: The CT images of 241 patients with enlargement of abdominal and pelvic lymph nodes involved by NHL were reviewed. Of them, 96 patients whose clinical and imaging data fulfilled the requirement for analysis were included. According to the Clinical Schema for the Lymphoid System, patients were divided into 3 subtypes, indolent lymphoma (IL; n=31), aggressive lymphoma (AL; n=61), very aggressive lymphoma (VAL; n=2), and unclassified lymphoma (UCL; n=2), respectively. Abdominal and pelvic CT scans were undertaken in 46 patients, abdominal CT only in 47 cases, and pelvic CT only in 3 cases. CT with iv contrast administration was obtained in 80 patients. Anatomic sites involved were nominated as retroperitoneal (i.e. paraaortic), abdominal (including paracardiac, gastrohepatic, hepatic hilar, and mesenteric etc), retrocrural, diaphragmatic, common iliac, internal iliac, external iliac, and inguinal nodes, respectively. Size, number, discreteness, and density of the nodal lesions were analyzed, and correlated with pathology subtypes. The minimal dimension of the largest node was measured. Results: (1) Size: Most of the nodes were ≤2 cm in size, 60.5% (219/362 sites) in IL and AL, 56.6% (77/136 sites) in IL, and 62.8%(142/226 sites) in AL, respectively. There was no statistical significant difference of the nodal size between IL and AL in each location (χ 2 =0.341, P=0.559). (2) Number: Mesentery had the largest number of node involvement (6.5 vs 5 nodes on an median, IL vs AL), with retroperitoneum placed second (4 vs 4 nodes, IL vs AL. (3) Discreteness: Most of the nodes were discrete with an incidence of 77.1% (279/362 sites, IL and AL), and 74.3% (101/136 sites) in IL, 78.8% (178/226 sites) in AL, respectively. No statistical significant discrepancy was found between

    Objectives: To investigate the frequency and possible role of Epstein-Barr virus infection in non-Hodgkin's lymphomas of the oral cavity and maxillofacial region in Khorasan (Northeast of Iran). Methods: The cross-sectional retrospective study assessed the frequency of Epstein-Barr virus infection in non-immunosuppressed non-Hodgkin's lymphoma cases of the oral cavity and maxillofacial region. Formalin-fixed, paraffin-embedded tissue sections from 34 cases of head and neck non-Hodgkin's lymphoma (17 low-grade B-cell lymphoma, 14 diffuse large B-cell lymphoma, and 3 peripheral T cell lymphoma) were selected as a case group, and 10 normal lymph node sections were considered as a control group. Polymerase chain reaction was used to detect the EBV-DNA in tissue specimens. SPSS 16 was used for statistical analysis of the data. Results: EBV-DNA was detected in 26.5% of NHL samples. Among NHLs, Epstein-Barr virus was found to be positive in 50% cases with diffuse large B-cell lymphoma and 11.8% of low grade B-cell lymphomas. Epstein-Barr virus was not detected in any cases of peripheral T-cell lymphoma. Conclusion: Although it seems that Epstein-Barr virus appears to be an etiological factor in some subtypes of non-Hodgkin's lymphomas, especially in diffuse large B-cell lymphoma, more researches should be done to investigate the relationship between Epstein-Barr virus infection and head and neck non-Hodgkin's lymphomas.

  16. Hypercalcemia and huge splenomegaly presenting in an elderly patient with B-cell non-Hodgkin's lymphoma: a case report

    2010-10-01

    Full Text Available Abstract Introduction Hypercalcemia is the major electrolyte abnormality in patients with malignant tumors. It can be due to localized osteolytic hypercalcemia or elaboration of humoral substances such as parathyroid hormone-related protein from tumoral cells. In hematological malignancies, a third mechanism of uncontrolled synthesis and secretion of 1-25(OH2D3 from tumoral cells or neighboring macrophages may contribute to the problem. However, hypercalcemia is quite unusual in patients with B-cell non-Hodgkin's lymphoma. Case presentation An 85-year-old Caucasian woman presented with low grade fever, anorexia, abdominal discomfort and fullness in her left abdomen for the last six months. She was mildly anemic and complained of fatigability. She had huge splenomegaly and was hypercalcemic. After correction of her hypercalcemia, she had a splenectomy. Microscopic evaluation revealed a malignant lymphoma. Her immunohistochemistry was positive for leukocyte common antigen, CD20 and parathyroid hormone-related peptide. Conclusion Immunopositivity for parathyroid hormone-related peptide clearly demonstrates that hypersecretion of a parathyroid hormone-like substance from the tumor had led to hypercalcemia in this case. High serum calcium is seen in only seven to eight percent of patients with B-cell non-Hodgkin's lymphoma, apparently due to different mechanisms. Evaluation of serum parathyroid hormone-related protein and 1-25(OH2D3 can be helpful in diagnosis and management. It should be noted that presentation with hypercalcemia has a serious impact on prognosis and survival.

    Non-Hodgkin lymphoma (NHL) is a frequent cancer and incidence rates have increased markedly during the second half of the 20(th) 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...... 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...

    The cyclin-dependent kinase inhibitor p27Kip1 is a negative cell cycle regulator linking extracellular growth-regulatory signals to the cell cycle machinery in G1. We investigated the pattern and prognostic value of p27Kip1 expression in a population-based group of 203 non-Hodgkin's lymphoma (NHL...... between p27Kip1 and Ki-67 expression. Low expression of p27Kip1, defined as nuclear p27Kip1 expression in lymphomas behaved differently as those with low p27Kip1...... expression tended to do better. Likewise, a high proliferation rate (Ki-67 >40%) was associated with poor survival in indolent and aggressive lymphomas. Multivariate analysis using the proportional hazards model showed that only p27Kip1, and not Ki-67, maintained independent prognostic significance...

    Low-dose radiotherapy over the last decade has been reported to provide effective palliation for patients with low-grade non-Hodgkin's lymphoma. In this retrospective case series of 10 patients, we report our early experience using low-dose radiotherapy (usually 2 x2 Gy) for patients with advanced-stage follicular, mucosal associated lymphoid tissue, mantle cell and small lymphocytic lymphomas. Median follow up was 27 weeks. Response rates were high (complete response, 70%; partial response, 20%), the response durable and the toxicity was minimal (no toxicity greater than grade 1).

    The diagnostic value of computed tomography (CT) was assessed in 17 patients with non-Hodgkin's lymphoma. CT was performed to evaluate the localization and types of pulmonary involvement caused by non-Hodgin's lymphoma. Using CT, it was possible to classify types of pulmonary involvements as hilar and/or mediastinum-nodular (13 cases), hilar and/or mediastinum-diffuse (4 cases), pleural effusion (5 cases), parenchymal-diffuse (1 case), and parenchymal-tumor (1 case). The pattern of hilar and/or mediastinum-diffuse seemed to be specific for lymphoblastic lymphoma. CT is useful to distinguish hilar and/or mediastinum-nodular to hilar and/or mediastinum-diffuse, and to provide better definition of the specific anatomic location of pulmonary involvements.

    Several epidemiological studies show the association between organophosphate pesticides (OPs) and the risk of non-Hodgkin lymphoma (NHL), yet various research results remain controversial. To explore the hazard of OPs exposure to human health, three kinds of OPs (Terbufos, Malathion, and Diazinon) that are non-halogenated aliphatic compounds were included in the meta-analysis. We searched PubMed and Web of Science Databases for articles published from 1985 to February 2017. The databases were also searched for eligible studies through a manual references search. The random-effect model was utilized to compute the odds ratios (ORs) and 95% confident intervals (CIs). A total of ten observational studies (five cohort, four case-control, and one nested case-control) were included in our meta-analysis, with a pooled OR of 1.22 (95% CI 1.04 to 1.43) of Malathion, Terbufos and Diazinion. The general heterogeneity for OR was moderate (P h  = 0.032, I 2  = 41.2%). The OR estimates in the subset analyses were utilized to compare the association between the three kinds of OPs and NHL; Terbufos (OR = 1.07, 95% CI 0.85 to 1.36) and Malathion (OR = 1.17, 95% CI 0.82 to 1.67) had a statistically non-significant relationship, whereas Diazinon (OR = 1.39, 95% CI 1.11 to 1.73) was significantly associated with an increased NHL risk. Because immune dysfunction was thought to increase NHL risk, the toxicity levels in the immune system of the three types of OPs were compared. Malathion attacked immune cells via a direct effect and Diazinon disrupted the neuro-immune system, which involves the cholinergic system of lymphocytes via indirect immune damage, whereas an immunotoxic effect involving Terbufos was not reported. Overall, the present meta-analysis indicated a statistically significant association between Diazinon exposure and NHL risk. - Highlights: • The present meta-analysis indicated a significantly positive association between Diazinon exposure and NHL risk.

    A retrospective analysis was performed about the survivals of 188 patients with non-Hodgkin's lymphoma (NHL) of head and neck who had been treated from April 1975 to March 1997 in the department of radiology and otorhinolaryngology at Kitasato University Hospital. According to the mode of received treatment, they were classified into three categories of time, as the times of radiotherapy only from 1975 to 1985 (n=52), of transition from 1986 to 1989 (n=47), and of chemoradiotherapy from 1990 to 1997 (n=89). The survival was studied about the whole patients and patients' groups of the three times concerning the candidates of prognostic factors, as gender, age, clinical stage, histopathological type, site of origin and initial serum LDH-values, using Kaplan-Meier's method with logrank test. The cause-specific 5-year survival rates were 68.0% for the whole patients (n=188), 80.6% for the patients' group of the time of radiotherapy only, 64.7% for the time of transition (n=47), and 62.6% for the time of chemoradiotherapy. No survival difference of statistical significance was proved between these three times of therapy mode. Except for the clinical stage of the whole patients and of the two times of radiotherapy only and transition, and for the initial serum LDH-value of the whole patients, no survival difference of statistical significance was proved in any time of therapy mode concerning all other prognostic factors enumerated above. The time gap between the practice of biopsy and the start of either radiotherapy or chemotherapy proved to be significantly longer for the time of chemoradiotherapy (10.7±9.1 days) than for that of radiotherapy only (3.2±5.3 days), and also significantly longer in less than 3-year survivors than in more than 5-year ones. In conclusion, radiotherapy only resulted in a better or at least not worse outcome than chemoradiotherapy and the timing of starting treatment came out to be a noticeable prognostic factor for the patients with NHL of

    2016-01-01

    The radioimmunotherapy (RIT) has proven to be a promising therapeutic modality, especially for therapy of hematological malignancies, which has stimulated the development of this type of radiopharmaceutical. Currently, there is one radioimmunoconjugate approved by Food and Drug Administration (FDA) for refractory or relapsed non-Hodgkin lymphoma (NHL) therapy, 90 Y-ibritumomab tiuxetan (Zevalin®), and it has higher overall response and complete remission rates compared to conventional treatments. However, Zevalin® is not commercially available in Brazil. In this context, the goal of this work was to study the steps involved in the process of conjugation and radiolabeling with Lu-177 of anti-CD20 monoclonal antibody, in order to consolidate the in house methodology for development of this radioimmunoconjugate, contributing for the treatment of patients with NHL and also contributing for the future development of other radioimmunoconjugates. In the studies performed to determine the best antibody: chelator (DOTA) molar ratio, the molar ratio 1:50, showed high radiochemical purity (greater than 95% after purification) and the immunoreactivity was higher than many published studies. Additionally, the immunoconjugate was stable for, at least, 3 months under refrigeration when conjugated by two different methods. The study of radiolabeling parameters, produced a radioimmunoconjugate with specific activity of 740 MBq/mg, with adequate stability that allowed the transportation of the radiopharmaceutical to nuclear medicine centers. The biodistribution and pharmacokinetic profiles were consistent with other radioimmunoconjugates in the literature. The radioimmunoconjugate showed tumor uptake and in vivo stability appreciable, the latter evidenced by low bone uptake. The lyophilization studies were performed for the optimized formulation of immunoconjugate that allowed the lyophilization without structural damage, evidenced by polyacrylamide gel electrophoresis, and with

    Full Text Available 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.

    Whilst many patients with indolent Non-Hodgkin's Lymphoma (NHL) can achieve clinical remissions to first-line chemotherapy and/or radiotherapy, most will relapse. Current treatment options for relapsing patients are limited since most patients become resistant to repeated chemotherapy. Death usually occurs within 10 years of diagnosis. Overall, these disappointing results have not changed significantly in a quarter of a century and clearly advocate the urgent priority to research into potential new therapeutic approaches into this diverse and increasingly prevalent group of human tumours. Radioimmunotherapy (RIT) is currently under investigation as a new approach for the treatment of this disease. In this form of treatment, radionuclide-labeled monoclonal antibodies are able to deliver selective systemic irradiation by recognising tumour-associated antigens. The use of RIT with radiolabeled anti-CD20 antibodies in patients with recurrent B-cell lymphoma has resulted in extremely high rates of durable complete remissions. The optimal approach and mechanisms of action of successful RIT remain however largely unknown. The work described in this thesis has focused on clarifying some of the important determinants and mechanisms of effective RIT of syngeneic B-cell lymphoma, both in vivo and in vitro. A successful animal model of RIT in B cell lymphomas was established by initially generating a panel of antibodies against mouse B cell antigens. The in vitro characteristics of these antibodies have been compared with their subsequent performance, in biodistribution studies and RIT in vivo. For the first time in an in vivo model the relative contributions of antibody and irradiation are described. Some antibodies including anti-MHC Class II were shown to be effective delivery vehicles of low doses of Iodine-131. These antibodies, which appear to be inactive delivery vehicles can cure animals with low burdens of tumour. However antibodies such as anti-idiotype and anti

    Full text: In this study, a monoclonal anti-CD20 was developed for radioimmunotherapy of non-Hodgkin's B-cell lymphoma by reacting anti-CD20 with iodine-131 using iodogen procedure. It was found that radiochemical yield was > 95 % independently of incubation time and the antibody could be conjugated with iodine-131 up to 10 mCi/mg. The radiolabeled antibody exhibited excellent retention of immunoreactivity with radio incorporations >95% for 6 hr at 4 o C. In vitro stability tests showed minimal loss of iodine-131 from the conjugate in the presence of cysteine and in human serum at 37 o C. Biodistribution study in normal ICR mice showed higher uptake by the liver, kidney and intestines but lower thyroid uptake compared to 131 I -MIBG. Biodistribution studies confirmed the in vitro stability of 131 I -anti-CD20. In particular, excellent in vivo retention of iodine-131 was demonstrated by lower thyroid accumulation over 48 hr. A favorable biological distribution of 131 I -anti-CD20 suggests this radiopharmaceutical may be effectively used in the therapy of non-Hodgkin's lymphoma

    Full Text Available Lymphoma was a common complication of HIV infection in the pre-antiretroviral era, and the incidence of HIV-associated lymphoma has dropped dramatically since the introduction of combination antiretroviral therapy (cART in resource-rich regions. Conversely, lymphoma is an increasingly common complication of HIV infection in resource-limited settings where the prevalence of HIV infection is high. Relatively little is known, however, about the true incidence and optimal treatment regimens for HIV-associated lymphoma in resource-poor regions. We review the epidemiology, diagnosis, and treatment of HIV-associated non-Hodgkin lymphoma in developing nations and highlight areas for further research that may benefit care in both settings. Examples include risk modification and dose modification of chemotherapy based on HIV risk factors, improving our understanding of the current burden of disease through national cancer registries, and developing cost-effective hematopathological diagnostic strategies to optimize care delivery and maximize use of available chemotherapy.

    Full Text Available Abstract Background Translocations are hallmarks of non-Hodgkin lymphoma (NHL genomes. Because lymphoid cell development processes require the creation and repair of double stranded breaks, it is not surprising that disruption of this type of DNA repair can cause cancer. The members of the MRE11-RAD50-NBS1 (MRN complex and BLM have central roles in maintenance of DNA integrity. Severe mutations in any of these genes cause genetic disorders, some of which are characterized by increased risk of lymphoma. Methods We surveyed the genetic variation in these genes in constitutional DNA of NHL patients by means of gene re-sequencing, then conducted genetic association tests for susceptibility to NHL in a population-based collection of 797 NHL cases and 793 controls. Results 114 SNPs were discovered in our sequenced samples, 61% of which were novel and not previously reported in dbSNP. Although four variants, two in RAD50 and two in NBS1, showed association results suggestive of an effect on NHL, they were not significant after correction for multiple tests. Conclusion These results suggest an influence of RAD50 and NBS1 on susceptibility to diffuse large B-cell lymphoma and marginal zone lymphoma. Larger association and functional studies could confirm such a role.

    Although physical activity is a well-established risk factor for several cancer types, studies evaluating its association with lymphoma have yielded inconclusive results. In such cases where physical activity is not clearly associated with cancer risk in a dose-dependent manner, investigators have begun examining physical inactivity as an independent exposure of interest. Associations of self-reported, lifetime physical inactivity with risk of developing Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) were evaluated in a hospital-based case control study using data from the Patient Epidemiology Data System at Roswell Park Comprehensive Cancer Center. Participants included 87 patients with HL and 236 patients with NHL as well as 348 and 952 cancer-free controls, respectively. Multivariable-adjusted logistic regression models were fit to calculate odds ratios (OR) and 95% confidence intervals (CI) estimating the association between physical inactivity and lymphoma risk. We observed significant, positive associations between lifetime recreational physical inactivity and risk of both HL (OR = 1.90, 95% CI: 1.15-3.15) and NHL (OR = 1.35, 95% CI: 1.01-1.82). The current analysis provides evidence for a positive association between physical inactivity and risk of both HL and NHL. These results add to a growing body of research suggesting that lifetime physical inactivity may be an important independent, modifiable behavioral risk factor for cancer.

    Thirty-nine patients with advanced non-Hodgkin's lymphoma (38 patients with lymphocytic lymphoma and 1 patient with mixed lymphocytic and histiocytic lymphoma) were treated by fractionated low dose whole body irradiation (WBI) with a minimum follow-up of 8 months. Twenty-eight patients had no previous treatment and the other 11 patients were in relapse after previous chemotherapy or regional radiotherapy. There were 20 and 19 patients in stages III and IV groups, respectively. The majority of patients (31) had nodular histology; diffuse lymphocytic lymphoma was present in 8 patients (Rappaport criteria) (9). Constitutional symptoms were present in 10 patients. Thirty-three (85%) attained complete remission (CR) with median duration of remission 24 months. Actuarial survival was 78% and 74% at 3 and 4 years. However, relapse free survival was 26% at 3 and 4 years. A prospective randomized trial to compare 10 vs. 15 rad per fraction of fractionated WBI schedules (the same total dose 150 rad) demonstrated no difference in response rate, response duration, and median nadir platelet or WBC counts between the two schedules. Supplement radiotherapy to bulky tumor site prevented local recurrence, but did not influence survival or duration or remission. Major toxicity was thrombocytopenia with median nadir platelet counts 77,000/mm 3 (11,000 to 170,000/mm 3 ). Five of 6 patients with diffuse lymphocytic poorly differentiated lymphoma attained CR. However, their median survival was 30 months which is much shorter than that of nodular lymphoma. Constitutional symptoms and advanced stage (stage IV) were associated with shorter duration of remission. Response of patients in relapse after WBI to subsequent chemotherapy +- local radiotherapy was CR in 50% and PR in 40%. Fractionated whole body irradiation is an excellent systemic induction agent for advanced lymphocytic and mixed lymphoma

    Rituximab is a patient-paid effective monoclonal-antibody drug for non-Hodgkin lymphoma (NHL). Little is known in China, a country with unequal distribution of wealth and medical insurance systems, about the impact of socioeconomic status (SES) on selecting rituximab therapy in NHL patients. A total of 328 NHL inpatients in 2 public hospitals in Hangzhou were recruited and divided into 2 equal groups: with rituximab therapy and with no rituximab therapy group. Selection and frequency of rituximab therapy increased with duration of education and in urban citizens (P inequality in provision of rituximab therapy among Chinese NHL patients, and this was associated with differences in SES status. Effective measures are suggested to ameliorate the inequality issue.

    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.

    Peripheral blood lymphocytes (PBL) and lymph node lymphocytes (LNL) from non-Hodgkin's lymphoma patients were tested for lymphokine-activated killer cells (LAK) cells cytotoxicity using appropriate targets in a short-term 51 chromium-release assay. The results showed a significant depression in LNL-LAK activity suggesting the reduced capacity of LNL to generate LAK cells. LNL-LAK cells demonstrated significantly low percentages of cells expressing CD16, CD56 and CD25 as compared to PBL-LAK and healthy donors. The reduced capacity to generate LAK cells in lymph nodes could by due to the presence of low numbers of natural killer cells which are thought to be the main precursors of LAK cells. The IL-2 producing ability of lymph node mononuclear cells was found to by significantly higher than that of peripheral blood mononuclear cells from both healthy donors and and NHL patients.

    CT was performed on 72 children with acute lymphoblasitc leukemia or non-Hodgkin's lymphoma. Thirty-two of these patients were investigated prior to CNS radiation and intrathecal methotrexate therapy. Ten of these patients (31%) were known to have hydrocephalic dilatation of the CSF spaces. Clinical data and subsequent observations with analysis of the CT findings show that no difference in the attenuation values of brain tissue occurs in the absence of a CNS relapse. The percentage of abnormal findings before and after therapy remains constant. The adverse late effects described in the CT literature seem principally to be damage diagnosed too late. It is questionable if the CT demonstration of dilated CSF spaces before treatment has a prognostic significance. (orig.)

    Two cases are presented of masses in muscle due to non-Hodgkin lymphoma (NHL) that were homogeneous and isoattenuating to normal muscle on CT. In each case, the mass was clinically suspected of representing soft tissue sarcoma. However, the masses were relatively inapparent on CT, being visible predominantly as mass effect - an appearance unlike that of soft tissue sarcomas. It is important to be aware that NHL in muscle can be difficult to detect at CT, even with intravenous contrast enhancement; therefore, a clinically apparent mass should not be dismissed on the basis of an apparently unremarkable CT scan of the region. Such findings should suggest the diagnosis of NHL rather than sarcoma. (orig.)

    Conjunctival lymphomas constitute 25% of all ocular adnexal lymphomas. The majority are B-cell non-Hodgkin lymphomas (NHLs) (98%), whereas conjunctival T-cell NHLs are rare (2%). The most frequent subtype of conjunctival B-cell lymphoma is extranodal marginal zone lymphoma (EMZL; 81%), followed...... by follicular lymphoma (8%), diffuse large B-cell lymphoma (3%), and mantle cell lymphoma (3%). Extranodal marginal zone lymphoma occurs slightly more often in women and, along with follicular lymphoma, presents late in the seventh decade of life, whereas diffuse large B-cell lymphoma and especially mantle cell...... lymphoma have a predilection for the male gender and typically present in the eighth decade. Extranodal marginal zone lymphoma and follicular lymphoma present most frequently in the forniceal and bulbar conjunctiva.

    Neurological disorders are common in HIV-infected patients. Central nervous system (CNS) lymphoma should always be considered because it is an important cause of morbidity and mortality. To investigate the clinical utility of flow cytometry immunophenotyping (FCI) in diagnosing or discarding leptomeningeal involvement in HIV-infected patients and to compare its sensitivity with that of conventional cytological methods. Fifty-six cerebrospinal fluid (CSF) samples from 29 HIV-infected patients were independently evaluated by flow cytometry and cytology. The description of an aberrant immunophenotype was the criterion used to define the malignant nature of any CSF cell population. FCI and cytology gave concordant results for 48 of the 56 CSF samples studied: 37 were negative for malignancy and 11 had evidence of CNS lymphoma. Discordant results were obtained for eight CSF samples, and the accuracy of the FCI findings could be demonstrated for four CSF samples described as positive for malignancy according to the FCI criteria. A high level of agreement was found between the results obtained using the two methods, but FCI gave at least 25% higher sensitivity than conventional cytomorphological methods for the detection of malignant cells. This advantage suggests that, in case of negative flow cytometry results, disorders other than non-Hodgkin's lymphoma should be strongly considered.

    The combination of cyclophosphamide, adriamycin, vincristine, and prednisone (CHOP) alternating with total body irradiation (TBI) has been shown earlier to be effective therapy in patients with malignant lymphoma who have received prior chemotherapy and/or radiation therapy. A limited institutional pilot study was therefore done by the Southwest Oncology Group between October 1977, and November 1978 to test the benefit of this program in previously untreated persons with Stages 3 and 4 diffuse histology non-Hodgkin's lymphoma. Eleven evaluable patients with the following histologies were treated: 7 poorly differentiated, 2 with histiocytic, 1 with mixed lymphoma and 1 with well-differentiated morphology. Responses were seen in 8/11 patients (6 CR and 2 PR); 5 persons are currently alive and 6 are dead. The median duration of remission is 15 months and the median survival for all patients is 48 months. The therapy was well tolerated with a mean nadir leukocyte count of 3020 x 10 9 /μl (range 1.2 to 5.5) and a mean nadir platelet count of 188 x 10 9 /μl (range 016 to 270). As delivered, this program is capable of producing durable remissions and needs to be verified in a larger series of patients

    Rituximab (RTX), a chimeric human anti-CD20 monoclonal antibody, is currently employed in the treatment of malignant non-Hodgkin's lymphoma (NHL) either alone or in combination with other cytotoxic approaches. The present study examines the effects of ionizing radiation in combination with RTX on proliferation and apoptosis development in B-lymphoma RL and Raji cells. RTX was used at a concentration of 10 μg/mL 24 hours prior to irradiation at a single dose of 9 Gy. CD20 expression, cell viability, apoptosis, mitochondrial membrane potential and apoptosis-related proteins were evaluated in the treated B cells. The constitutive level of CD20 expression in RL and Raji lymphoma cells did not play an essential role in RTX-induced cell growth delay. Both lymphoma cells showed similar inhibition of cell proliferation without apoptosis development in response to RTX treatment. Exposure to ionizing radiation induced cell growth delay and apoptosis in RL cells, whereas Raji cells showed moderate radio-resistance and activation of cell growth at 24 hours after irradiation, which was accompanied by increased radiation-triggered CD20 expression. The simultaneous exposure of lymphoma cells to ionizing radiation and RTX abrogated radioresistance of Raji cells and significantly enhanced cell growth delay and apoptosis in RL cells. X-linked inhibitor of apoptosis protein (XIAP) and the inducible form of heat shock protein 70 (Hsp70) were positively modulated by RTX in combination with ionizing radiation in order to induce apoptosis. Furthermore, it was demonstrated that mitochondrial membrane potential dissipation is not an essential component to induce apoptosis-inducing factor (AIF) maturation and apoptosis. Our results show that RTX-triggered enhancement of radiation-induced apoptosis and cell growth delay is achieved by modulation of proteins involved in programmed cell death. (author)

    Purpose: To evaluate outcomes of patients treated for aggressive non-Hodgkin lymphoma (NHL) with combined modality therapy based on [{sup 18}F]fluoro-2-deoxy-2-D-glucose positron emission tomography (FDG-PET) response. Methods and Materials: We studied 59 patients with aggressive NHL, who received chemotherapy and radiation therapy (RT) from 2001 to 2008. Among them, 83% of patients had stage I/II disease. Patients with B-cell lymphoma received R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone)-based chemotherapy, and 1 patient with anaplastic lymphoma kinase-negative anaplastic T-cell lymphoma received CHOP therapy. Interim and postchemotherapy FDG-PET or FDG-PET/computed tomography (CT) scans were performed for restaging. All patients received consolidated involved-field RT. Median RT dose was 36 Gy (range, 28.8-50 Gy). Progression-free survival (PFS) and local control (LC) rates were calculated with and without a negative interim or postchemotherapy FDG-PET scan. Results: Median follow-up was 46.5 months. Thirty-nine patients had negative FDG-PET results by the end of chemotherapy, including 12 patients who had a negative interim FDG-PET scan and no postchemotherapy PET. Twenty patients were FDG-PET-positive, including 7 patients with positive interim FDG-PET and no postchemotherapy FDG-PET scans. The 3-year actuarial PFS rates for patients with negative versus positive FDG-PET scans were 97% and 90%, respectively. The 3-year actuarial LC rates for patients with negative versus positive FDG-PET scans were 100% and 90%, respectively. Conclusions: Patients who had a positive interim or postchemotherapy FDG-PET had a PFS rate of 90% at 3 years after combined modality treatment, suggesting that a large proportion of these patients can be cured with consolidated RT.

Methodology:Demographics including age, gender, histopathology, stage and outcome data, in biopsy proven NHL patients were analyzed. Burkitts/B Cell and Diffuse Large B Cell lymphoma patients were treated with MCP 842 Protocol while T/B-cell lymphoblastic lymphoma (LL) patients were treated with EURO-LB 02 protocol. Results:Ninety-one patients were treated during the study period at CHL. Data was insufficient in 18 patients, so they were excluded from the study. Patients included were 73. Males were 53 (72.6%). Thirty-seven (50.7%) were 5-10 years of age, and 22 (30.1%) 10-16 years old. Abdominal mass was the commonest presentation seen in 32 (43.8%), lymphadenopathy in 27 (37%), intussusception in 5 (6.8%), while intestinal obstruction, obstructive uropathy, nasopharyngeal mass, gastric mass, primary bone lymphoma, pericardial effusion, jaw swelling, cheek swelling and paraspinal mass present in one (1%) each. Histopathological subtypes consist of Burkitt's lymphoma (BL) in 32 (43.8%), B cell NHL in 10 (13.7%), lymphoblastic lymphoma (LL) in 26 (35.6%), diffuse large B cell lymphoma (DLBCL) in 2 (2.8%), and anaplastic large cell lymphoma (ALCL) in 1 (1.4%). Sixty-seven (91%) presented in stage III, and six (8.4%) in stage IV. Forty-eight (65.8%) patients had completed treatment and are well to date, 16 (21.9%) died, 5 (6.8%) left against medical advice (LAMA), and 4 (5.5%) patients relapsed. Conclusion:Burkitt's lymphoma was the commonest type of NHL seen in this cohort that predominantly presented with an abdominal mass. Children usually presented in advanced stage with delayed diagnosis. Better supportive care can improve the prognosis

    Epigenetic inactivation of tumor suppressor genes (TSG) by promoter CpG island hypermethylation is a hallmark of cancer. To assay its extent in human lymphoma, methylation of 24 TSG was analyzed in lymphoma-derived cell lines as well as in patient samples. We screened for TSG methylation using methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) in 40 lymphoma-derived cell lines representing anaplastic large cell lymphoma, Burkitt lymphoma (BL), diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), Hodgkin lymphoma and mantle cell lymphoma (MCL) as well as in 50 primary lymphoma samples. The methylation status of differentially methylated CD44 was verified by methylation-specific PCR and bisulfite sequencing. Gene expression of CD44 and its reactivation by DNA demethylation was determined by quantitative real-time PCR and on the protein level by flow cytometry. Induction of apoptosis by anti-CD44 antibody was analyzed by annexin-V/PI staining and flow cytometry. On average 8 ± 2.8 of 24 TSG were methylated per lymphoma cell line and 2.4 ± 2 of 24 TSG in primary lymphomas, whereas 0/24 TSG were methylated in tonsils and blood mononuclear cells from healthy donors. Notably, we identified that CD44 was hypermethylated and transcriptionally silenced in all BL and most FL and DLBCL cell lines, but was usually unmethylated and expressed in MCL cell lines. Concordant results were obtained from primary lymphoma material: CD44 was not methylated in MCL patients (0/11) whereas CD44 was frequently hypermethylated in BL patients (18/29). In cell lines with CD44 hypermethylation, expression was re-inducible at mRNA and protein levels by treatment with the DNA demethylating agent 5-Aza-2'-deoxycytidine, confirming epigenetic regulation of CD44. CD44 ligation assays with a monoclonal anti-CD44 antibody showed that CD44 can mediate apoptosis in CD44 + lymphoma cells. CD44 hypermethylated, CD44 - lymphoma cell lines were consistently

    Radioimmunotherapy targeting CD20 receptors in lymphoma using radiolabeled chimeric antibodies may lead to better therapeutic responses than cold anti-CD20 antibodies. This study aimed to assess the biodistribution and present reasonable estimates of normal organ doses, including red marrow using Lu-DOTA-rituximab. Patients with relapsed/refractory CD20+ B-cell non-Hodgkin's lymphoma were recruited into this prospective study. In-house labeling of Lu-DOTA-rituximab was performed and administered after quality assurance. Rituximab (375 mg/m), followed by 50 mCi (1850 MBq) of Lu-DOTA-rituximab was administered as a slow intravenous infusion and emission images were acquired. Regions of interest were drawn for kidney, liver, heart, bladder, spleen, and tumor lesions on both anterior and posterior images. Internal dose estimation was performed using OLINDA v1.0 software. The mean age of the 10 patients (eight men and two women) was 52±13 years. The uptake of radiolabeled antibody was visualized within 30 min of administration in the liver, kidneys, heart, spleen, and bladder. The coefficient of determination (R) was greater than 0.95 for organs and the whole body in all patients. The effective half-life of radioimmunoconjugate was 100±28 h (42-126 h). The critical organ in our study was the red marrow. The average total body dose, effective dose, and effective dose equivalent calculated in all 10 patients were 0.13±0.02, 0.15±0.03, and 0.22±0.04 mGy/MBq, respectively. There may be considerable interindividual differences in absorbed doses of organs and generalization or extrapolation of doses in the clinical setting at present is not feasible with Lu-DOTA-rituximab in non-Hodgkin's lymphoma patients. Patient-specific dosimetry is thus recommended to eliminate the variations and reduce the possibility of dose-limiting toxicity.

    Allo-SCT is used to exploit GVL effect in high-risk relapsed non-Hodgkin's lymphoma (NHL). Here, we retrospectively analyzed 34 high-risk NHL patients who underwent auto-SCT followed closely by reduced-intensity allo-SCT ('tandem auto-allo') from January 2002 to November 2010. The search for an allogeneic donor was started at the beginning of salvage regimen. Median patients' age was 47 (27-68) years; histotypes were: diffuse large B-cell n=5, follicular n=14, transformed follicular n=4, mantle-cell n=5, plasmocytoid lymphoma n=1, anaplastic large T-cell n=2, peripheral T-cell n=3. Donors were HLA-identical siblings (n=29) or 10/10-matched unrelated individuals (n=5). Median interval between auto-SCT and allo-SCT was 77 days (36-197). At a median follow-up of 46 (8-108) months since allo-SCT, 5-year OS is 77% (61-93) and PFS is 68% (51-85). Disease relapse or progression occurred in six patients, 100-day TRM was 0%, 2-year TRM incidence was 6%. In conclusion, tandem transplantation is feasible in high-risk NHL patients having a HLA-identical donor. This approach could represent a suitable therapeutic option for those patients with high-risk NHL potentially benefitting from further therapy after auto-SCT. Donor searches should be started promptly whenever such an approach is chosen.

    Limited comparative data exist for the treatment of HIV-associated non-Hodgkin lymphoma. We analyzed pooled individual patient data for 1546 patients from 19 prospective clinical trials to assess treatment-specific factors (type of chemotherapy, rituximab, and concurrent combination antiretroviral [cART] use) and their influence on the outcomes complete response (CR), progression free survival (PFS), and overall survival (OS). In our analysis, rituximab was associated with a higher CR rate (odds ratio [OR] 2.89; P < .001), improved PFS (hazard ratio [HR] 0.50; P < .001), and OS (HR 0.51; P < .0001). Compared with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), initial therapy with more dose-intense regimens resulted in better CR rates (ACVBP [doxorubicin, cyclophosphamide, vindesine, bleomycin and prednisolone]: OR 1.70; P < .04), PFS (ACVBP: HR 0.72; P = .049; “intensive regimens”: HR 0.35; P < .001) and OS (“intensive regimens”: HR 0.54; P < .001). Infusional etoposide, prednisone, infusional vincristine, infusional doxorubicin, and cyclophosphamide (EPOCH) was associated with significantly better OS in diffuse large B-cell lymphoma (HR 0.33; P = .03). Concurrent use of cART was associated with improved CR rates (OR 1.89; P = .005) and trended toward improved OS (HR 0.78; P = .07). These findings provide supporting evidence for current patterns of care where definitive evidence is unavailable. PMID:24014242

  20. Inherited Inflammatory Response Genes Are Associated with B-Cell Non-Hodgkin's Lymphoma Risk and Survival.

    Full Text Available Malignant B-cell clones are affected by both acquired genetic alterations and by inherited genetic variations changing the inflammatory tumour microenvironment.We investigated 50 inflammatory response gene polymorphisms in 355 B-cell non-Hodgkin's lymphoma (B-NHL samples encompassing 216 diffuse large B cell lymphoma (DLBCL and 139 follicular lymphoma (FL and 307 controls. The effect of single genes and haplotypes were investigated and gene-expression analysis was applied for selected genes. Since interaction between risk genes can have a large impact on phenotype, two-way gene-gene interaction analysis was included.We found inherited SNPs in genes critical for inflammatory pathways; TLR9, IL4, TAP2, IL2RA, FCGR2A, TNFA, IL10RB, GALNT12, IL12A and IL1B were significantly associated with disease risk and SELE, IL1RN, TNFA, TAP2, MBL2, IL5, CX3CR1, CHI3L1 and IL12A were, associated with overall survival (OS in specific diagnostic entities of B-NHL. We discovered noteworthy interactions between DLBCL risk alleles on IL10 and IL4RA and FL risk alleles on IL4RA and IL4. In relation to OS, a highly significant interaction was observed in DLBCL for IL4RA (rs1805010 * IL10 (rs1800890 (HR = 0.11 (0.02-0.50. Finally, we explored the expression of risk genes from the gene-gene interaction analysis in normal B-cell subtypes showing a different expression of IL4RA, IL10, IL10RB genes supporting a pathogenetic effect of these interactions in the germinal center.The present findings support the importance of inflammatory genes in B-cell lymphomas. We found association between polymorphic sites in inflammatory response genes and risk as well as outcome in B-NHL and suggest an effect of gene-gene interactions during the stepwise oncogenesis.

    We conducted a population-based case–control study in Connecticut women to test the hypothesis that genetic variations in Th1 and Th2 cytokine genes modify the relationship between hormone replacement therapy (HRT) and risk of non-Hodgkin lymphoma (NHL). Compared to women without a history of HRT use, women with a history of HRT use had a significantly decreased risk of NHL if they carried IFNGR2 (rs1059293) CT/TT genotypes (OR = 0.5, 95%CI: 0.3–0.9), IL13 (rs20541) GG genotype (OR = 0.6, 95%CI: 0.4–0.9), and IL13 (rs1295686) CC genotype (OR = 0.6, 95%CI: 0.4–0.8), but not among women who carried IFNGR2 CC, IL13 AG/AA, and IL13CT/TT genotypes. A similar pattern was also observed for B-cell lymphoma but not for T-cell lymphoma. A statistically significant interaction was observed for IFNGR2 (rs1059293 P for interaction = 0.024), IL13(rs20541 P for interaction = 0.005), IL13 (rs1295686 P for interaction = 0.008), and IL15RA (rs2296135 P for interaction = 0.049) for NHL overall; IL13 (rs20541 P for interaction = 0.0009), IL13(rs1295686 P for interaction = 0.0002), and IL15RA (rs2296135 P for interaction = 0.041) for B-cell lymphoma. The results suggest that common genetic variation in Th1/Th pathway genes may modify the association between HRT and NHL risk.

    Periodontal disease is a chronic inflammatory condition that has been associated with chronic diseases, including cancer. In an earlier prospective cohort analysis within the Health Professionals Follow-Up Study (HPFS), we observed a 31% higher risk of non-Hodgkin lymphoma (NHL) among participants with severe periodontal disease at baseline. Here, we extend the study with an additional 8 years of follow-up, and conduct analyses with updated periodontal disease status and NHL subtypes. The HPFS is an ongoing prospective cohort study of 51,529 men in the USA Between baseline in 1986 and 2012, 875 cases of NHL were diagnosed, including 290 chronic lymphocytic leukemia/small lymphocytic lymphomas (CLL/SLL), 85 diffuse large B-cell lymphomas and 91 follicular lymphomas. We performed multivariable Cox proportional hazards regression to evaluate associations of interest. History of periodontal disease at baseline was positively associated with risk of NHL overall (hazard ratio (HR) = 1.26, 95% confidence interval (CI): 1.06-1.49) and CLL/SLL (HR = 1.41, 95% CI: 1.04-1.90). With updated periodontal status, HRs were 1.30 (95% CI: 1.11-1.51) for NHL overall and 1.41 (95% CI: 1.08-1.84) for CLL/SLL. In contrast, after adjusting for periodontal disease, tooth loss was inversely associated with NHL, suggesting that other causes or consequences of tooth loss may have different implications for NHL etiology. Our findings suggest that periodontal disease is a risk factor for NHL. Whether periodontal disease is a direct or indirect cause of NHL, or is a marker of underlying systemic inflammation and/or immune dysregulation, warrants further investigation. © 2016 UICC.

    Objective: to describe the main imaging findings of non-Hodgkin's lymphoma presenting as a single liver mass. Materials and methods: a retrospective study was developed with analysis of cases where a single liver mass was observed at ultrasonography, computed tomography and magnetic resonance imaging, and histologically diagnosed as non-Hodgkin's lymphoma. The studies were reviewed by two observers in consensus. Results: three male patients in the fifth decade of life, with non-specific clinical manifestations and single liver mass diagnosed as non-Hodgkin's lymphoma were identified. A hepatic lesion with target sign was observed at ultrasonography in all of the cases. At computed tomography, all the patients presented a heterogeneous, hypodense mass with a ring enhancement. At magnetic resonance imaging, the lesions were heterogeneous and hypointense on T1-weighted and hyperintense on T2-weighted images. Additionally, a ring enhancement was observed in all of the cases after contrast injection. At the moment of the diagnosis, none of the patients presented lymphadenomegaly or involvement of other solid viscera. Conclusion: the diagnosis of hepatic lymphoma should be considered in the presence of a ring-enhanced single liver mass. (author)

    Full Text Available Much has been learned about how HIV-induced immune dysfunction contributes to B cell hyperactivation, and potentially, to the pathogenesis of AIDS-lymphoma. However, further studies are needed to fully understand how HIV infection and immune dysfunction promote B cell hyperactivation and the development/growth of AIDS-lymphoma. In particular, studies are needed to define the role of HHV8 vIL6, IL6 receptor-expression, and lymphocyte surface stimulatory molecules, in promoting B cell hyperactivation or lymphoma cell growth.

    Full Text Available Rituximab enhances treatment efficacy of B-lineage lymphoma by targeting CD20+ B-cells. Such target therapies may compromise the immune system and render patients susceptible to opportunistic infections. We report 2 cases of lymphoma complicated with Pneumocystis jiroveci (previously known as P. carinii pneumonia (PCP while being treated with rituximab-containing chemotherapy regimens. In both cases, PCP developed during the neutropenic period. With timely diagnosis and proper management, both were treated successfully. We searched the literature and found that such opportunistic infection occurred only infrequently in lymphoma patients, and it has not been reported in the large-scale clinical trials of rituximab. Such cases demonstrate the importance of taking PCP into diagnostic consideration in lymphoma patients receiving similar therapies.

    Full Text Available Malignant lymphoma may occur in the oral cavity and oropharynx, but is most commonly located in Waldeyer's ring, particularly in the palatine and lingual tonsil. The occurrence of malignant lymphoma in the tongue is very rare. Clinical features are nonspecific ulcerative lesions that do not heal. In the literature, the majority of casesare non-Hodgkin’s lymphoma, diffuse large B cell type; however T-cell phenotype also may occur. We describe a 60-year-old man who presented with an ulcerative mass in the left lateral aspect of his tongue, unresponsive to medical therapy. After tissue biopsy, histopathological and immunohistochemical analyses confirmed a diagnosis of non-Hodgkin’s lymphoma, diffuse large B cell type.

    To explore the expression and clinical significance of P-glycoprotein (P-gp)/mdr1mRNA, multidrug resistance-associated protein (MRP) and lung resistance protein (LRP) in newly diagnosed non-Hodgkin's lymphoma. mdr1 mRNA of in 41 patients with non-Hodgkin's lymphoma was assayed by semi-quantitative RT-PCR. The expressions of P-gp, MRP and LRP proteins in lymph node viable blasts were identified by flow cytometry. The results were compared with those obtained from control cases, and the correlation of the changes with clinical outcomes was analyzed. (1) Among the 41 cases, the positive expression of P-gp protein was detected in 8 cases, MRP in 7 cases, LRP in 15 cases, and mdr 1 mRNA in 11 cases. (2) The P-gp and LRP levels in NHL were significantly higher than those in control group, but MRP wasn't. The P-gp over-expression was significantly associated with mdr1mRNA (r = 0.396, P = 0.01). No correlation was showed among the expressions of P-gp, MRP and LRP. (3) Patients with P-gp expression had a poorer outcome of chemotherapy than those with P-gp-negative (P = 0.005). P-gp expression was significantly associated with higher clinical stage (P = 0.046) and elevated serum lactate dehydrogenase level (P = 0.032), but not associated with malignant degree (P = 0.298). MRP had no impact on the outcome of chemotherapy (P = 0.212), and wasn't significantly associated with higher clinical stage (P = 0.369), elevated LDH (P = 0.762) and higher malignant degree (P = 0.451). Patients with LRP expression had a poorer outcome of chemotherapy than those LRP-negative (P = 0.012). LRP expression was significantly associated with higher clinical stage (P = 0.0019), elevated LDH (P = 0.02) and higher malignant degree (P = 0.01). The data of this study indicate that P-gp and LRP expressions but not MRP expression are important in the mechanism of drug resistance associated with a poor clinical outcome in previously untreated NHL.

    Full Text Available BACKGROUND: Non-Hodgkin's lymphoma (NHL has been widely 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 survival and prognosis of NHL patients. To evaluate the role of such genetic variations in prognosis of NHL, we conducted this study in a Chinese population. METHODS: We used the TaqMan assay to genotype six single nucleotide polymorphisms (SNPs (TNF rs1799964T>C, LTA rs1800683G>A, IL-10 rs1800872T>G, LEP rs2167270G>A, LEPR rs1327118C>G, TNFAIP8 rs1045241C>T for 215 NHL cases. Kaplan-Meier analysis was performed to compare progression free survival among two common genotypes. Cox proportional hazard models were used to identify independent risk factors. RESULTS: We observed that LTA rs1800683G>A was significantly associated with risk of progression or relapse in NHL patients (HR = 1.63, 95%CI = 1.06-2.51; P = 0.028, particularly in Diffuse large B cell lymphoma (DLBCL cases (HR = 1.50, 95%CI = 1.10-2.04, P = 0.01. Both univariate and multivariate Cox regression analysis showed that in DLBCL patients, Ann Arbor stage III/IV, elevated LDH level before treatment and LTA rs1800683 AA genotype carrier were independent risk factors for progression or relapse. While in NK/T cell lymphoma, Ann Arbor stage III/IV and elevated β2-MG level before treatment indicated poorer prognosis. CONCLUSIONS: The polymorphism of LTA rs1800683G>A contributes to NHL prognosis in a Chinese population. Further large-scale and well-designed studies are needed to confirm these results.

    Anaemia is a common feature of lympho-proliferative disorders and is an important cause of poor quality of life in these patients. When indicated, packed red blood cells (PRBC) units are transfused to treat anaemia. Objective of this study was to identify risk factors associated with PRBC transfusions in lymphoma patients. Methods: This was a retrospective study done on Hodgkin lymphoma (HL) and Non-Hodgkin lymphoma (NHL) patients who had PRBC transfusions during chemotherapy. Information regarding gender, type of lymphoma, stage, baseline haemoglobin, marrow involvement and total number of PRBC units transfused was collected. Results: A total of 481 patients with diagnosis of HL and NHL were registered during one year period. Out of these, 108 (22.4%) had PRBC transfusions during treatment. HL and NHL patients were 30 (27.8%) and 78 (72.2%) respectively. NHL patients were older than HL (37 vs. 32 years), (p=0.03). HL patients had lower mean haemoglobin 9. 2.56 g/dl as compared to NHL 11.33 ± 2.42 g/dl, (p<0.05). There was significant difference in number of PRBC units transfused based on lymphoma type (NHL 6.74 ± 5.69 vs. HL 3.97 ± 3.0 units, p<0.05). Bone marrow involvement resulted in increased transfusion requirements (7.84 ± 4.36 vs. 5.26 ± 5.49 units, p<0.05) while stage of disease didn't affected significantly (I/II-4.88 ± 4.85 and III/IV 6.30 ± 5.33 units p=0.2). Conclusion: A significant number of lymphoma patients need PRBC transfusions during chemotherapy. NHL patients and bone marrow involvement makes patients at higher risk for transfusions. In places, where blood bank support is not adequate, patients should be informed right from beginning to arrange donors for possible transfusions during chemotherapy. (author)

    One hundred sixty-three patients with advanced non-Hodgkin's lymphoma including adult T cell leukemia/lymphoma (ATL) were treated from 1981 to 1983 with VEPA (vincristine, cyclophosphamide, prednisolone, and doxorubicin) or VEPA-M (VEPA plus methotrexate) in randomized fashion after stratification by surface marker. The complete response (CR) rate and the 4-year survival rate of patients treated with VEPA-M was 62.2% and 36.9%, respectively, while for those treated with VEPA the rates were 51.9% and 26.6, respectively. The difference was not statistically significant, but pretreatment characteristics predictive for response and survival were interesting. Three factors, leukemic change, poor performance status (PS), and T cell marker, were negatively associated with both CR and survival rates, and high-grade pathology was adversely associated with survival rate in a multivariate analysis. These prognostic factors are somewhat different from those in Western lymphomas. This may be reflection of major differences in patients' characteristics between Japanese and Western lymphomas: in this study, there was a high incidence of T cell lymphoma/leukemia (50%) including ATL (33%), leukemic manifestation (34%), poor PS (34%), and a low incidence of follicular lymphoma (9%). The statistically significant three factors for both CR and survival rates were used to construct a model containing eight categories of patients at increasing risk for poor response and shortened survival. These categories were divided into four groups, with respective CR and 4-year survival rates of 91% and 73%, 67% and 35%, 27% and 7%, and 10% and 5%. Ninety-three patients in whom CR was induced by VEPA or VEPA-M therapy were evaluated for prognostic factors predictive for disease-free survival. A shorter period (less than 28 days) required to achieve CR, a clinical diagnosis of ATL, and a lower hemoglobin level were found to affect disease-free survival adversely. These results have important

    The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 51-year-old healthy female with good performance status presented for gynecologic surgery for a benign condition. A preprocedure chest x-ray showed a right lower lobe infiltrate. A subsequent computed tomography (CT) scan of the chest with contrast revealed a large consolidative right lower lobe mass with surrounding inflammation ( Fig 1A ). Bronchoscopy with biopsy revealed a low-grade lymphoma with the following immunophenotype: CD45 + , CD20 + , BCL2 + , CD10 negative, CD5 negative, cyclin D1 negative, and Ki-67 index of less than 5%. Morphology and immunohistochemistry were most consistent with pulmonary extranodal marginal zone lymphoma (ENMZL; Fig 2 ). The patient was asymptomatic and denied fevers, sweats, weight loss, shortness of breath or dyspnea on exertion, or cough. Her history was notable for exposure to parrots over several months before presentation. Complete staging with a CT of the chest, abdomen, and pelvis with contrast redemonstrated disease that was localized to the chest with mild compression of the pulmonary vasculature but no other evidence of lymphoma. She was referred to discuss management of stage I AE pulmonary ENMZL lymphoma.

    Outcome of HIV-infected patients with AIDS-related lymphomas has improved during recent years. However, data on incidence, risk factors, and outcome of relapses in AIDS-related lymphomas after achieving complete remission are still limited. This prospective observational multicenter study includes HIV-infected patients with biopsy- or cytology-proven malignant lymphomas since 2005. Data on HIV infection and lymphoma characteristics, treatment and outcome were recorded. For this analysis, AIDS-related lymphomas patients in complete remission were analyzed in terms of their relapse- free survival and potential risk factors for relapses. In total, 254 of 399 (63.7%) patients with AIDS-related lymphomas reached a complete remission with their first-line chemotherapy. After a median follow up of 4.6 years, 5-year overall survival of the 254 patients was 87.8% (Standard Error 3.1%). Twenty-nine patients relapsed (11.4%). Several factors were independently associated with a higher relapse rate, including an unclassifiable histology, a stage III or IV according to the Ann Arbor Staging System, no concomitant combined antiretroviral therapy during chemotherapy and R-CHOP-based compared to more intensive chemotherapy regimens in Burkitt lymphomas. In conclusion, complete remission and relapse rates observed in our study are similar to those reported in HIV-negative non-Hodgkin lymphomas. These data provide further evidence for the use of concomitant combined antiretroviral therapy during chemotherapy and a benefit from more intensive chemotherapy regimens in Burkitt lymphomas. Modifications to the chemotherapy regimen appear to have only a limited impact on relapse rate. Copyright © 2018 Ferrata Storti Foundation.

  14. Absence of annexin I expression in B-cell non-Hodgkin's lymphomas and cell lines

    Full Text Available Abstract Background Annexin I, one of the 20 members of the annexin family of calcium and phospholipid-binding proteins, has been implicated in diverse biological processes including signal transduction, mediation of apoptosis and immunosuppression. Previous studies have shown increased annexin I expression in pancreatic and breast cancers, while it is absent in prostate and esophageal cancers. Results Data presented here show that annexin I mRNA and protein are undetectable in 10 out of 12 B-cell lymphoma cell lines examined. Southern blot analysis indicates that the annexin I gene is intact in B-cell lymphoma cell lines. Aberrant methylation was examined as a cause for lack of annexin I expression by treating cells 5-Aza-2-deoxycytidine. Reexpression of annexin I was observed after prolonged treatment with the demethylating agent indicating methylation may be one of the mechanisms of annexin I silencing. Treatment of Raji and OMA-BL-1 cells with lipopolysaccharide, an inflammation inducer, and with hydrogen peroxide, a promoter of oxidative stress, also failed to induce annexin I expression. Annexin I expression was examined in primary lymphoma tissues by immunohistochemistry and presence of annexin I in a subset of normal B-cells and absence of annexin I expression in the lymphoma tissues were observed. These results show that annexin I is expressed in normal B-cells, and its expression is lost in all primary B-cell lymphomas and 10 of 12 B-cell lymphoma cell lines. Conclusions Our results suggest that, similar to prostate and esophageal cancers, annexin I may be an endogenous suppressor of cancer development, and loss of annexin I may contribute to B-cell lymphoma development.

    Lymphoma is one of the most frequent cancers in adolescent and young adults. Hodgkin Lymphoma is curable in more than 90% of cases. Recent pediatric and adults protocols aimed to decrease long term toxicities (mostly gonadic and cardiovascular) and secondary malignancies, reducing the use of alkylating agents and limiting radiation fields. Risk-adapted strategies, using positron emission tomography staging, are about to become a standard, both in adult and pediatric protocols. These approaches allow obtaining excellent results in adolescents with Hodgkin lymphoma. On the other hand, treatment of adolescents with diffuse large B-cell lymphoma raises some questions. Even through children have good outcomes when treated with risk-adapted strategies, adolescents who are between 15 and 18 years old seem to experience poorer survivals, whereas patients older than 18 years old have globally the same outcome than older adults. This category of patient needs a particular care, based on a tight coordination between adults and pediatric oncologists. Primary mediastinal lymphomas, a subtype of BLDCL frequent in young adult population, exhibits poorer outcomes in children or young adolescent population than in older ones. Taking together, B-cell lymphoma benefited from recent advances in immunotherapy (in particular with the extended utilization of rituximab) and metabolic response-adapted strategies. In conclusion, adolescent and young adult's lymphomas are very curable diseases but require a personalized management in onco-hematological units. Copyright © 2016 Société Française du Cancer.

    Full Text Available In economically developed countries, AIDS-related lymphoma (ARL accounts for a large proportion of malignances in HIV-infected individuals. Since the introduction of highly active anti-retroviral therapy (HAART in 1996, epidemiology and prognosis of ARL have changed. While there is a slight increase in the incidence of Hodgkin’s lymphoma in HIV-infected individuals, use of HAART has contributed to a decline in the incidence of non-Hodgkin’s lymphoma (NHL and also a decrease in the overall incidence of ARL. Strategies that employ HAART, improved supportive care, and the use of Rituximab with multi-agent chemotherapy have contributed to improved rates of complete remission and survival of patients with ARL that rival those seen in stage and histology matched HIV negative NHL patients. Most recent clinical trials demonstrate better outcomes with the use of rituximab in ARL. Tumor histogenesis (germinal center vs. non-germinal center origin is associated with lymphoma-specific outcomes in the setting of AIDS-related diffuse-large B cell lymphoma. High-dose chemotherapy (HDCT and autologous stem cell rescue (ASCT can be effective for a subset of patients with relapsed ARL. HIV sero-status alone should not preclude consideration of ASCT in the setting of ARL relapse. Clinical trials investigating the role of allogeneic hematopoietic stem cell transplant in ARL are currently underway.

    Non-Hodgkin lymphoma of the bone is rare and typically causes an extensive bone lesion. The present study describes a case of diffuse large B-cell primary non-Hodgkin lymphoma of the bone, which occurred in the right femur, and was initially treated with surgery and chemotherapy. Following a 7-year period of complete remission, a new, similar lesion was identified in the left femur. With both lesions, there was no accompanying destruction of any other bones or organ involvement. Metastasis of PLB to the contralateral side is extremely rare and, to the best of our knowledge, this is the first report of this particular presentation in China or worldwide. We hypothesized that the present situation arose due to mechanisms involving the tumor microenvironment, circulating tumor cells, lymphocyte homing and self-seeding. The present report describes the case in detail, and discusses the possible underlying mechanisms and their potential contribution to the treatment of non-Hodgkin lymphoma, as well as the prevention of metastasis and recurrence, which may be of considerable clinical significance.

    Purpose: To examine the usefulness and safety of a new treatment regimen consisting of irradiation to the involved area and adjacent lymph node area, and reduced dose chemotherapy for elderly patients with non-Hodgkin's lymphoma. Methods and Materials: The core of this study was 38 elderly patients older than 65 years old with intermediate or high grade non-Hodgkin's lymphoma, and concomitantly suffering from some other geriatric disease. They received involved area irradiation (40 Gy), adjacent lymph node irradiation (30 Gy), and reduced dose chemotherapy (two cycles of 50-70% ACOP: Doxorubicin, Cyclophosphamide, Vincristine, Prednisone or 70% MACOP-B: Doxorubicin, Cyclophosphamide, Vincristine, Methotrexate, Bleomycin, Prednisone for 4 weeks). Results: The completion rate of the treatment regimen was 100%. The 5-year local control rate was 98%. The 5-year disease-free survival rate and the 5-year cause-specific survival rate for all patients were 70 and 82%, respectively. No treatment deaths were observed, and the rate of serious complications arising from the treatment was 3%. Conclusions: The newly conducted treatment regimen proved to be safe and useful for elderly patients with non-Hodgkin's lymphoma concomitantly suffering from some other geriatric disease

    Substantial heterogeneity has been observed among case-control studies investigating associations between non-Hodgkin's lymphoma and familial characteristics, such as birth order and sibship size. The potential role of selection bias in explaining such heterogeneity is considered within this study. Selection bias according to familial characteristics and socioeconomic status is investigated within a United Kingdom-based case-control study of non-Hodgkin's lymphoma diagnosed during 1998-2001. Reported distributions of birth order and maternal age are each compared with expected reference distributions derived using national birth statistics from the United Kingdom. A method is detailed in which yearly data are used to derive expected distributions, taking account of variability in birth statistics over time. Census data are used to reweight both the case and control study populations such that they are comparable with the general population with regard to socioeconomic status. The authors found little support for an association between non-Hodgkin's lymphoma and birth order or family size and little evidence for an influence of selection bias. However, the findings suggest that between-study heterogeneity could be explained by selection biases that influence the demographic characteristics of participants.

    This case report explores the potential role of FDG PET/CT in HIV -associated systemic non-Hodgkin's lymphoma (HIV-NHLs). In our locality, there are a cumulative total of 5523 reported HIV infections cases since 1984. We reported a case of HIV-related Burkitt's lymphoma (BL) and a case of diffuse large B-cell lymphoma (DLBCL) that underwent PET/CT examination in our PET centre. In HIV-NHLs patients, we must be reminded that not all hypermetabolic foci represent lymphomatous lesions. There is a close correlation between the pattern of lymphoid tissue activation in FDG PET/CT and HIV progression in patients without HIV-related malignancy. The unique patterns of lymphoid tissue activation observed in HIV-infected patients have great clinical implications. Secondly, HIV-infected patients are prone to suffer from opportunistic infections due to immunosuppression, particularly in those with high levels of HIV viral loads. FDG PET/CT cannot reliably differentiate metabolic active lymphoma from other benign diseases such as inflammation in the context of low CD4 count and high viral loads. In those cases, benign markedly hypermetabolic foci can be erroneously interpreted as lymphoma, particularly in those normal-sized lymph nodes. Furthermore, FDG PET/CT may be useful for assessing the efficacy of HAART in suppressing HIV replication and detecting its complication such as lipodystrophy. FDG PET/CT may play a potential useful role in staging and management of HIV -associated systemic non-Hodgkin's lymphoma. Plasma variables such as viral loads and CD4 count must be taken into account during image interpretation. FDG PET/CT as a potential useful tool for diagnosis, treatment response assessment and disease relapse detection in HIV -associated systemic non-Hodgkin's lymphoma worth to be further explored

    2011-06-01

    Full Text Available Abstract Introduction Many cancers are associated with inferior vena cava (IVC obstruction, but very few cancers have the ability to propagate within the lumen of the renal vein or the IVC. Renal cell carcinoma is the most common of these cancers. Renal cancer with IVC extension has a high rate of recurrence and a low five year survival rate. Case presentation A 62-year-old Caucasian woman previously in good health developed the sudden onset of severe reflux symptoms and right-sided abdominal pain that radiated around the right flank. A subsequent ultrasound and CT scan revealed a right upper pole renal mass with invasion of the right adrenal gland, liver, left renal vein and IVC. This appeared to be consistent with stage III renal cancer with IVC extension. Metastatic nodules were believed to be present in the right pericardial region; the superficial anterior abdominal wall; the left perirenal, abdominal and pelvic regions; and the left adrenal gland. The pattern of these metastases, as well as the invasion of the liver by the tumor, was thought to be atypical of renal cancer. A needle biopsy of a superficial abdominal wall mass revealed a surprising finding: The malignant cells were diagnostic of large-cell, B-cell non-Hodgkin's lymphoma. The lymphoma responded dramatically to systemic chemotherapy, which avoided the need for nephrectomy. Conclusion Lymphomas only rarely progress via intraluminal vascular extension. We have been able to identify only one other case report of renal lymphoma with renal vein and IVC extension. While renal cancer would have been treated with radical nephrectomy and tumor embolectomy, large-cell B-cell lymphomas are treated primarily with chemotherapy, and nephrectomy would have been detrimental. It is important to remember that, rarely, other types of cancer arise from the kidney which are not derived from the renal tubular epithelium. These may be suspected if an atypical pattern of metastases or unusual

    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 and Materials: 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 according to Radiation Therapy Oncology Group (RTOG) acute toxicity criteria were identified in univariate analysis using the Pearson χ{sup 2} 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 grades 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 therapy (10%, P=.019). Several dosimetric parameters predicted RP, including mean lung dose of >13.5 Gy, V{sub 20} of >30%, V{sub 15} of >35%, V{sub 10} of >40%, and V{sub 5} of >55%. The likelihood ratio χ{sup 2} value was highest for V{sub 5} >55% (χ{sup 2} = 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. Patients with relapsed

    Full Text Available Primary gastric non-Hodgkin's lymphoma (NHL is a co-morbidity that can be observed during the clinical course of acquired immunodeficiency syndrome (AIDS. We evaluated the prevalence, clinical-evolutive aspects and form of endoscopic presentation of primary gastric NHL associated with AIDS. Two hundred and forty-three HIV patients were submitted to upper digestive endoscopy, with evaluation of clinical, endoscopic and histological data. A CD4 count was made by flow cytometry and viral load was determined in a branched-DNA assay. Six cases (five men; mean age: 37 years; range: 29-46 years of primary gastric NHL were detected. The median CD4 count was 140 cells/mm³ and the median viral load was 40,313 copies/mL. Upper digestive endoscopy revealed polypoid (in four patients ulcero-infiltrative (two patients and ulcerated (two patients lesions and combined polypoid and ulcerated lesions (two patients. Histology of the gastric lesions demonstrated B cell NHL (four patients and T cell NHL (two patients. Five of the six patients died of complications related to gastric NHL. We concluded that primary gastric NHL is an important cause of mortality associated with AIDS.

  10. Autophagy plays a critical role in ChLym-1-induced cytotoxicity of non-hodgkin's lymphoma cells.

    Directory of Open Access Journals (Sweden)

    Jiajun Fan

    Full Text Available Autophagy is a critical mechanism in both cancer therapy resistance and tumor suppression. Monoclonal antibodies have been documented to kill tumor cells via apoptosis, antibody-dependent cellular cytotoxicity (ADCC and complement-dependent cytotoxicity (CDC. In this study, we report for the first time that chLym-1, a chimeric anti-human HLA-DR monoclonal antibody, induces autophagy in Raji Non-Hodgkin's Lymphoma (NHL cells. Interestingly, inhibition of autophagy by pharmacological inhibitors (3-methyladenine and NH4Cl or genetic approaches (siRNA targeting Atg5 suppresses chLym-1-induced growth inhibition, apoptosis, ADCC and CDC in Raji cells, while induction of autophagy could accelerate cytotoxic effects of chLym-1 on Raji cells. Furthermore, chLym-1-induced autophagy can mediate apoptosis through Caspase 9 activation, demonstrating the tumor-suppressing role of autophagy in antilymphoma effects of chLym-1. Moreover, chLym-1 can activate several upstream signaling pathways of autophagy including Akt/mTOR and extracellular signal-regulated kinase 1/2 (Erk1/2. These results elucidate the critical role of autophagy in cytotoxicity of chLym-1 antibody and suggest a potential therapeutic strategy of NHL therapy by monoclonal antibody chLym-1 in combination with autophagy inducer.

    The relationship between nitrate levels in drinking water and increased risk of non-Hodgkin lymphoma (NHL) development has been inconclusive. A matched cancer case-control and a nitrate ecology study was used to investigate the association between mortality attributed to NHL and nitrate exposure from Taiwan's drinking water. All deaths due to NHL in Taiwan residents from 2000 through 2006 were obtained from the Bureau of Vital Statistics of the Taiwan Provincial Department of Health. Controls were deaths from other causes and were pair-matched to the cases by gender, year of birth, and year of death. Each matched control was selected randomly from the set of possible controls for each case. Data on nitrate-nitrogen (NO(3)-N) levels of drinking water throughout Taiwan were collected from the Taiwan Water Supply Corporation (TWSC). The municipality of residence for cancer cases and controls was presumed to be the source of the subject's nitrate exposure via drinking water. The adjusted odds ratios (OR) for NHL death for those with high nitrate levels in their drinking water, as compared to the lowest tertile, were 1.02 (0.87-1.2) and 1.05 (0.89-1.24), respectively. The results of the present study show that there was no statistically significant association between nitrates in drinking water at levels in this investigation and increased risk of death attributed to NHL.

    Background: The potential role of neutron therapy in the management of intermediate-grade non-Hodgkin lymphoma (IGNHL) has not been examined because of the belief that the anticipated radiobiological effectiveness (RBE) would be uniformly very low. Purpose: To determine the fast neutron RBE for two chemotherapy-resistant IGNHL cell lines. Methods and Materials: Conventional soft agar clonogenic survival curves following irradiation by 60 Co and fast neutron were established for two IGNHL cell lines. These cell lines, WSU-DLCL2 and SK-DHL2B, were found in previous studies to be able to repair sublethal damage, and were also resistant to L-Pam and doxorubicin chemotherapy. Results: When the surviving fraction after 2 Gy photon was chosen as the biological endpoint, the RBE for WSU-DLCL2 and SK-DHL2B measured 3.34 and 3.06. Similarly, when 10% survival was considered, the RBE for these two cell lines measured 2.54 and 2.59. The RBE, as measured by the ratios α neutron/α photon, for WSU-DLCL2, SK-DHL2B cell lines are 6.67 and 5.65, respectively. These results indicate that the RBE for these IGNHL cell lines is higher than the average RBE for cell lines of other histological types. Conclusion: Fast neutron irradiation may be of potential value in treating selected cases of IGNHL

    Expression of six proto-oncogenes (fos, myc, myb, Ki-ras, Ha-ras, and N-ras) in 43 cases of non-Hodgkin's lymphoma was analyzed by means of in situ hybridization. Biotinylated DNA probes of the six oncogenes and those of the immunoglobulin H-chain (IgH) gene and the T cell receptor β-chain (TCRβ) gene were used. The results of in situ hybridization performed under blind conditions by IgH and TCRβ gene probes were compatible with those of typing by cell surface markers. The nuclear protein-related proto-oncogenes, fos myc, and myb, were expressed in about 70 % - 80 % of all cases regardless of phenotypes, histology or histologic grade. On the contrary, genes of the ras family were expressed in fewer cases except for the Ki-ras gene which was more frequently expressed by cases of the T cell immunophenotype with a high malignancy grade. The results of dot hybridization with RNA extracted from some cases were compatible with those of in situ hybridization, further demonstrating the specificity of in situ hybridization. (author)

    Salvage reinduction therapy followed by high-dose chemotherapy (HDCT) and auto-SCT is the treatment of choice for fit patients with refractory or relapsed aggressive non-Hodgkin's lymphoma (NHL). We assessed the prognostic value of comorbidity at the time of relapse to predict receipt of auto-SCT and outcome. We analyzed 156 consecutive NHL patients, referred to our center between 1999 and 2007 for salvage reinduction therapy, followed by HDCT and auto-SCT. Comorbidity according to the hematopoietic SCT comorbidity index was scored at relapse and directly before HDCT and auto-SCT. Primary end points were actual receipt of auto-SCT and survival. At relapse, comorbidity scores of 0, 1-2 and ≥3 were found among 64 (41%), 62 (40%) and 30 (19%) patients, respectively. Ultimately, 95 patients received auto-SCT. Higher comorbidity scores at relapse were associated with significantly less chance of receiving auto-SCT and with inferior OS, independently from secondary age-adjusted International Prognostic Index (sAAIPI) scores. For transplanted patients, OS rates at 5 years were 62, 30 and 17% for relapse comorbidity scores of 0, 1-2 and ≥3, respectively. In patients with relapsed NHL, comorbidity at relapse is associated with receipt of auto-SCT and subsequent survival independently from the sAAIPI.

    Etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin (EPOCH)-containing regimens are frequently utilized in non-Hodgkin's lymphoma, however, the incidence of febrile neutropenia (FN) in patients receiving inpatient versus outpatient EPOCH has not been described. Additionally, no comparisons have been made regarding financial implications of EPOCH administration in either setting. This study's primary objective was to compare hospital admissions for FN in patients receiving inpatient or outpatient EPOCH. A single-center, institutional review board-approved review was conducted for adults receiving EPOCH beginning January 2010. Clinical and financial data were collected through chart review and the institution's financial department. Descriptive statistics were utilized for analysis. A total of 25 patients received 86 cycles of an EPOCH-containing regimen (61 [70.9%] inpatient). Five (8.2%) inpatient cycles resulted in an admission for FN compared to 4 (16%) outpatient cycles. Prophylactic antifungal and antiviral agents were prescribed more often after inpatient cycles (>80%) compared to outpatient cycles (cost savings of approximately US$141 116 for both chemotherapy costs and hospital day avoidance. EPOCH-containing regimens can be safely administered in the outpatient setting, which may result in cost savings for healthcare institutions.

    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.

    This study investigated sleep quality and health-related quality of life (HRQOL) among long-term survivors of Hodgkin (HL) and non-Hodgkin lymphoma (NHL). The aim was to explore the impact of personal and health-related factors on sleep quality as well as associations between sleep quality and HRQOL. For the postal survey, participants with a minimum age of 18 years initially treated between 1998 and 2008 were recruited via the population-based cancer registry in Schleswig-Holstein, Northern Germany. Questionnaires included amongst others the Pittsburg Sleep Quality Index (PSQI) and the 36-Item Short Form Health Survey (SF-36v1). Descriptive and comparative statistics were performed. Additionally, a regression analysis was conducted to identify predictors of sleep quality. In total, we recruited 515 participants (398 NHL, 117 HL) with a mean age of 63.1 years. Approximately half of the survivors were classified as good sleepers. HRQOL scores differed between good and poor sleepers with lower scores in poor sleepers. In a prediction model, self-reported depression, exhaustion, higher age, inability to work, endocrinological disorders and female gender classified as predictors of sleep quality. This study highlights the impact of sleep quality on HRQOL in long-term survivors of NHL and HL. Thus, sleep quality should be routinely assessed during follow-up of cancer survivors with special attention to patients with potential risk factors.

    Radioimmunotherapy (RIT) with anti CD20 MoAb conjugated to a β{sup -} emitting radioisotope like {sup 131}I or {sup 90}Y has the added advantage of delivering radiation not only to tumor cells that bind the antibody but also due to a crossfire effect, to neighboring tumor cells inaccessible to the antibody. In order to make available an indigenous radioimmunotherapeutic agent for Non Hodgkin's Lymphoma (NHL), radioiodinated Rituximab has been prepared and evaluated at a clinical scale. Radioiodination of Rituximab was performed by the conventional Chloramine T method using 7.4 GBq Na{sup 131}I in a lead shielded plant. Six batches of radioiodination were prepared and characterized by electrophoresis and HPLC to evaluate the reproducibility of the product. The product remained stable retaining the radiochemical purity > 95% upto 5 days after radioiodination. In vitro cell binding studies and biodistribution studies in normal Swiss mice have indicated the potential of this molecule as a radioimmunotherapeutic agent for NHL. (orig.)

    Tripartite motif containing 28 (TRIM28) as a transcriptional co-repressor has been reported playing a role in regulating DNA damage response (DDR), cell differentiation, immune response, and tumorigenesis. The present study was performed to explore the biological function and clinical significance of TRIM28 in B-cell non-Hodgkin lymphoma (B-NHL). Results of the study displayed that high expression of TRIM28 was positively associated with the poorer survival of B-NHL patients as an independent prognostic factor. In addition, TRIM28 could promote the B-NHL cells proliferation through modulating cell cycle progression. The change of cyclinA, P21, and PCNA expression after TRIM28 expression modified further illustrated the mechanism in which TRIM28 participated in cell proliferation progression. Moreover, inhibition TRIM28 expression in B-NHL cells enhanced the sensibility to Bortezomib by regulating p53-mediated apoptosis pathway. Taken together, the present study showed that TRIM28 functions as a tumor promoter in B-NHL and may be a novel target for drug resistance to Bortezomib.

    Hepatitis C virus (HCV)-infection can cause hepatocellular carcinoma (HCC) and most likely non-Hodgkin lymphoma (NHL). No studies have compared the risk of these cancers between patients with chronic and cleared HCV-infection. The aim of this study was to estimate the 10-year risk of HCC and NHL...... in HCV-infected patients and to compare the risk of these cancers between HCV-infected patients and the general population in Denmark and between patients with chronic and cleared HCV-infection. Nationwide cohorts were used: 11,975 HCV-infected patients in the DANVIR cohort and 71,850 individuals from...... an age- and gender-matched general population cohort. Within DANVIR, 4,158 patients with chronic HCV-infection and 2,427 patients with cleared HCV-infection were studied. The 10-year risks of HCC and NHL in HCV-infected patients were 1.0% (95% confidence interval (CI): 0.8 - 1.3%) and 0.1% (95% CI: 0...

    PET using {sup 18}F-FDG for treatment monitoring in patients with lymphoma is one of the most well-developed clinical applications. PET/CT is nowadays used during treatment to assess chemosensitivity, with response-adapted therapy given according to 'interim' PET in clinical practice to adults and children with Hodgkin lymphoma. PET is also used to assess remission from disease and to predict prognosis in the pretransplant setting. Mature data have been reported for the common subtypes of aggressive B-cell lymphomas, with more recent data also supporting the use of PET for response assessment in T-cell lymphomas. The Deauville five-point scale incorporating the Deauville criteria (DC) is recommended for response assessment in international guidelines. FDG uptake is graded in relation to the reference regions of normal mediastinum and liver. The DC have been validated in most lymphoma subtypes. The DC permit the threshold for adequate or inadequate response to be adapted according to the clinical context or research question. It is important for PET readers to understand how the DC have been applied in response-adapted trials for correct interpretation and discussion with the multidisciplinary team. Quantitative methods to perform PET in standardized ways have also been developed which may further improve response assessment including a quantitative extension to the DC (qPET). This may have advantages in providing a continuous scale to refine the threshold for adequate/inadequate response in specific clinical situations or treatment optimization in trials. qPET is also less observer-dependent and limits the problem of optical misinterpretation due to the influence of background activity.

    The broad category of non-Hodgkin's lymphoma includes a large variety of different diseases including indolent as well as aggressive lymphomas. Mucosa-associated lymphoid tissue (MALT) lymphoma arises in the extranodal mucosal lymphoid tissue and has only been recognised as a distinct entity in recent years. It affects one or several extranodal structures such as the stomach, the lung, the eye and salivary glands. The lymphoma is generally of low grade and has indolent course. The aim of this article is to exemplify the most common radiological patterns of MALT lymphoma. (orig.)

    Full Text Available Angiogenesis is important in development, maintenance and progression of haematological malignancies. Some clinical observations have indicated that in non-Hodgkin's lymphoma (nHL tumour microvessel density (MVD may correlate with tumour staging and outcome. The aim of the study was to examine relationship between MVD as a parameter of tumour angiogenesis measured by expression of CD34 and the grade of nHL histological malignancy as determined by REAL classification. 40 lymph node samples of patients with newly diagnosed nHL (17 women, 23 men; aged 48-70 yrs, median age 64 yrs; stage III and IV and treated at the Department of Haematology, Wrocław Medical University in 1999-2002 were fixed in 10% buffered formalin and embedded in paraffin. In all the studied cases, sections were incubated with antibodies against CD34. The slides were stained with hematoxylin and eosin and evaluated histopathologically. Patients were divided into two groups according to histological malignancy: indolent nHL (19 patients and aggressive nHL (21 patients. Mean MVD measured by expression of CD34 in aggressive and indolent nHL groups amounted to 19.45 +/- 11.24 vessels/0.375 mm2 and 21.7 +/- 12.4 vessels/0.375 mm2, respectively. Statistical analysis of microvessel staining demonstrated no correlation between tumour MVD and grade of histological malignancy in lymph nodes of nHL patients. Nevertheless, angiogenesis observed in nHL provides rationale for use of angiogenesis inhibitors in lymphoma therapy.

    Little is known about the trajectory of post-traumatic stress disorder (PTSD) symptoms in cancer survivors, despite the fact that such knowledge can guide treatment. Therefore, this study examined changes in PTSD symptoms among long-term survivors of non-Hodgkin's lymphoma (NHL) and identified demographic, clinical, and psychosocial predictors and correlates of PTSD symptomatology. Surveys were mailed to 682 NHL survivors who participated in an earlier survey and now were at least 7 years postdiagnosis. Information was obtained regarding PTSD symptoms, positive and negative perceptions of the cancer experience (ie, impact of cancer), and other potential correlates of PTSD. A total of 566 individuals participated (83% response rate) with a median of 12.9 years since diagnosis; respondents were 52% female and 87% white. Although half (51%) of the respondents reported no PTSD symptoms and 12% reported a resolution of symptoms, more than one-third (37%) reported persistence or worsening of symptoms over 5 years. Survivors who reported a low income, stage ≥ 2 at diagnosis, aggressive lymphoma, having received chemotherapy, and greater impact of cancer (both positive and negative) at the initial survey had more PTSD symptoms at follow-up. In multivariable analysis, income and negative impacts of cancer were independent predictors of PTSD symptoms. More than one-third of long-term NHL survivors experience persisting or worsening PTSD symptoms. Providers should be aware of enduring risk; early identification of those at prolonged risk with standardized measures and treatments that target perceptions of the cancer experience might improve long-term outcomes.

    The aim of this study was to evaluate the safety, toxicity and therapeutic response of non-myeloablative radioimmunotherapy using 131 I-rituximab in previously heavily treated patients with B-cell non-Hodgkin's lymphoma (B-NHL). Nine patients with relapsed, refractory or transformed B-NHL received ten radioimmunotherapies. Patients had a median of 5 (range 2-7) prior standard therapies. Four patients had received prior high-dose chemotherapy followed by autologous stem cell transplantation, and eight had received prior rituximab therapy. Histopathology consisted of four mantle cell, one follicular and four diffuse large B-cell lymphomas. Rituximab, a monoclonal chimeric anti-CD20 antibody (IDEC-C2B8), was labelled with 131 I using the Iodogen method. The administered activity (2,200±600 MBq) was based on a dosimetrically calculated 45 cGy total-body radiation dose. All patients received an infusion of 2.5 mg/kg of rituximab prior to administration of the radiopharmaceutical. No acute adverse effects were observed after the administration of 131 I-rituximab. Radioimmunotherapy was safe in our patient group and achieved one complete response ongoing at 14 months and two partial responses progressing at 12 and 13 months after treatment. One partial responder was re-treated with radioimmunotherapy and achieved an additional progression-free interval of 7 months. Four non-responders with bulky disease died 4.8±2.0 months after therapy. Three patients had an elevated serum lactate dehydrogenase (LDH) level prior to radioimmunotherapy and none of the patients responded. Of two patients who received radioimmunotherapy as an additional treatment after salvage chemotherapy, one continues to be disease-free at 9 months and one relapsed at 5 months' follow-up. Reversible grade 3 or 4 haematological toxicity occurred in seven of nine patients. Median nadirs were 35 days for platelets, 44 days for leucocytes and 57 days for erythrocytes. (orig.)

    Available data suggest that respiratory infections are associated with increased morbidity and mortality in patients hospitalized due to acute leukemia and allogeneic stem cell transplantation (allo-SCT). However, the precise incidence, risk factors, and severity of respiratory infection, mainly community-acquired, in patients with lymphoma and multiple myeloma (MM) are not fully determined. The current study aimed to investigate risk factors for respiratory infections and their clinical significance in patients with B cell non-Hodgkin lymphoma (NHL) and multiple myeloma (MM) in the first year of diagnosis. Data of consecutive patients diagnosed with NHL or MM and treated at the Rambam Hematology Inpatient and Outpatient Units between 01/2011 and 03/2012 were evaluated. Information regarding anticancer treatment, incidence and course of respiratory infections, and infection-related outcomes was analyzed. One hundred and sixty episodes of respiratory infections were recorded in 103 (49%) of 211 (73-MM, 138-NHL) patients; 126 (79%) episodes were community-acquired, 47 (29%) of them required hospitalization. In univariate analysis, age respiratory infection risk (P = 0.058, 0.038, and 0.001, respectively). Ninety episodes (56% of all respiratory episodes) were examined for viral pathogens. Viral infections were documented in 25/90 (28%) episodes, 21 (84%) of them were community-acquired, requiring hospitalization in 5 (24%) cases. Anti-flu vaccination was performed in 119 (56%) patients. Two of the six patients diagnosed with influenza were vaccinated. Respiratory infections, including viral ones, are common in NHL and MM. Most infections are community-acquired and have a favorable outcome. Rapid identification of viral pathogens allows avoiding antibiotic overuse in this patient population.

    Abdominal Non-Hodgkin lymphomas (NHL) are the most common extra nodal presentation of pediatric NHL. Our aim is to assess the role of surgery as a risk factor and to evaluate the impact of risk-adjusted systemic chemotherapy on survival of patients with stages II and III disease. This study included 35 pediatric patients with abdominal NHL treated over five years at South Egypt Cancer Institute (SECI), Assiut University, between January 2005 and January 2010. The data of every patient included: Age, sex, and presentation, staging work up to determine extent of the disease and the type of resection performed, histopathological examination, details of chemotherapy, disease free survival and overall survival. The study included 25 boys and 10 girls with a median age of six years (range: 2.5:15). Thirty patients (86%) presented with abdominal pain, 23 patients (66%) presented with abdominal mass and distention, 13 patients (34%) presented with weight loss, and intestinal obstruction occurred in six patients (17%). The ileo-cecal region and abdominal lymph nodes were the commonest sites (48.5%, 21% respectively). Burkitt's lymphoma was the most common histological type in 29 patients (83%). Ten (28.5%) stage II (group A) and 25 (71.5%) stage III (group B). Complete resections were performed in 10 (28.5%), debulking in 6 (17%) and imaging guided biopsy in 19 (54%). A11 patients received systemic chemotherapy. The median follow up duration was 63 months (range 51-78 months). The parameters that significantly affect the overall survival were stage at presentation complete resection for localized disease. In conclusion, the extent of disease at presentation is the most important prognostic factor in pediatric abdominal NHL. Surgery is restricted to defined situations such as; abdominal emergencies, diagnostic biopsy and total tumor extirpation in localized disease. Chemotherapy is the cornerstone in the management of pediatric abdominal NHL.

    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. 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. 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 (1.1-160kilograms (kg)) vs. Level 1: risk ratio 1.56 [1.44-1.68], Level 5 (>160kg) vs. Level 1: 1.60 [1.48-1.74]). 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. Copyright © 2016 The Authors.

    Primary non- Hodgkin's lymphomas of the breast (PNHLB) are an infrequent malignancy. In a review of the literature, in which six Latin American journals are included, approximately 450 cases have been reported during the past two decades. in this paper we present the experience of the national cancer institute of Colombia during the last 23 years. Objective: to carry out a retrospective analysis of the characteristics, natural history, prognostic factors, and outcome of patients with PNHLB at the NCI of Colombia. Methods: the medical histories of patients diagnosed with PNHLB between 1980 and 2003 were reviewed; likewise, the clinical characteristics, treatment protocols, and final outcomes were analyzed. Results: 25 patients were identified as PNHLB. The average follow-up was 57 months. The medium age was 58, ranging from 26 to 83. 84% had diffused large cell lymphoma. The Karnofsky index was over 80 in 92% of the patients. 72% received chop chemotherapy. Two patients received a combination without doxorubicin. 68% received combined chemo- and radiation therapy. Two patients refused therapy. Two patients died before receiving any type of treatment. CNS compromise was observed in 20% of patients during the evolution of their disease. The youngest patient, whose case deserves special comment, obtained a second complete remission with simple mastectomy, after having relapsed after conventional chemotherapy, radiotherapy, and autologous bone marrow transplant. No significant prognostic variables were found using the univariate analysis. Conclusions: a high rate of complete remission can be achieved by using combined treatment in patients with PNHLB. The medium overall survival was not reached after 71 months of follow-up. The most frequent relapse site was the CNS

    Full Text Available Neurolymphomatosis (NL is a rare clinical disease where neoplastic cells invade the cranial nerves and peripheral nerve roots, plexus, or other nerves in patients with hematologic malignancy. Most NL cases are caused by B-cell non-Hodgkin’s lymphoma (NHL. Diagnosis can be made by imaging with positron emission tomography (PET and magnetic resonance imaging (MRI. We experienced two cases of NL involving the brachial plexus in patients with NHL. One patient, who had NHL with central nervous system (CNS involvement, experienced complete remission after 8 cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy but relapsed into NL of the brachial plexus 5 months later. The other patient, who suffered from primary central nervous system lymphoma (PCNSL, had been undergoing chemoradiotherapy but progressed to NL of the brachial plexus.

    Full Text Available We are interested in investigating whether cancer therapy may alter the mitochondrial redox state in cancer cells to inhibit their growth and survival. The redox state can be imaged by the redox scanner that collects the fluorescence signals from both the oxidized-flavoproteins (Fp and the reduced form of nicotinamide adenine dinucleotide (NADH in snap-frozen tissues and has been previously employed to study tumor aggressiveness and treatment responses. Here, with the redox scanner we investigated the effects of chemotherapy on mouse xenografts of a human diffuse large B-cell lymphoma cell line (DLCL2. The mice were treated with CHOP therapy, i.e., cyclophosphamide (C + hydroxydoxorubicin (H + Oncovin (O + prednisone (P with CHO administration on day 1 and prednisone administration on days 1–5. The Fp content of the treated group was significantly decreased (p = 0.033 on day 5, and the mitochondrial redox state of the treated group was slightly more reduced than that of the control group (p = 0.048. The decrease of the Fp heterogeneity (measured by the mean standard deviation had a border-line statistical significance (p = 0.071. The result suggests that the mitochondrial metabolism of lymphoma cells was slightly suppressed and the lymphomas became less aggressive after the CHOP therapy.

    The authors report the findings of a national survey conducted at the request for the French Society for Rheumatology to list the rheumatic manifestations that can be inaugural in Hodgkin's disease on non-Hodgkin's malignant lymphoma. This was an exploratory, retrospective, descriptive study of 146 patients from 22 rheumatology departments. A number of clinical features (young male, nocturnal sweats, generalized pruritus, protracted fever, central or peripheral lymphadenopathy) and laboratory test abnormalities (evidence of severe inflammation) considerably increased the likelihood of Hodgkin's disease rather than malignant lymphoma. The diagnosis of bony involvement requires multidisciplinary studies of tumor specimens. (authors). 4 figs., 7 tabs., 71 refs

    Full Text Available Erythema multiforme major (EMM is a hypersensitivity reaction usually secondary to medications, viruses or other infections. Its presentation is fairly typical with a symmetrical distribution of vesicles, bullae or targeted lesions on the upper body, arms, legs, palms, feet and oral mucosa. The authors present a delineated case of EMM in association with chronic lymphocytic leukemia (CLL and non-Hodgkin′s lymphoma (NHL with a very unusual clinical presentation evolving overtime into a unique, almost dermatomal distribution. Typical therapies were not initially helpful and intravenous immunoglobulin antibody had to be administered.

    Neck pain is a common reason for seeking medical attention. It affects at least 15% of the labor force and up to 40% of individuals whose occupation is hazardous. On the other hand, primary bone lymphoma is a very rare disease (less than 1% of all malignant bone tumors), and the relationship between the 2 has rarely been mentioned. We report the case of a patient who had a 1-month history of neck pain. The main symptom was pain on palpation of C2-C6 cervical spinous processes and contracture of the trapezius muscle that did not cease with conventional treatment. Imaging studies indicated an abnormality. He underwent surgery and the results of vertebral biopsy were compatible with diffuse large B-cell lymphoma. He was treated with radiotherapy with a good outcome. Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología. All rights reserved.

    Full Text Available Imatinib is an important example of tyrosine kinase inhibitors (TKIs used in clinical practice. Imatinib blocks the ATP binding site of the Bcr-Abl fusion protein and selectively inhibits Bcr-Abl tyrosine kinase (TK activity. Treatment of chronic myelocytic leukemia (CML with imatinib is encouraging and it has an acceptable toxicity profile, and as such has changed the management of CML during the last decade. As with all drugs used in clinical practice, side effects of imatinib have been reported in studies with extended follow-up periods. In addition, some neoplastic disorders have been reported to occur during imatinib therapy. Herein we present a CML case that developed non-Hodgkin’s lymphoma (NHL while receiving imatinib treatment.

    Despite complex treatment schedules for cancer, the occurrence of resistances and relapses is a major concern in oncology. Hence, novel treatment options are needed. In this thesis, different approaches using radioimmunotherapy and the opioid D,L-methadone alone or in combination with doxorubicin were analyzed regarding their cytotoxic potential and the triggered signalling pathways in sensitive and resistant leukaemia and non-Hodgkin lymphoma (NHL). The radioimmunoconjugates [Bi-213]anti-CD33 and [Bi-213]anti-CD20 for treatment of acute myeloid leukaemia (AML) or NHL, respectively, were applied exemplary for the use of targeted alpha-therapies (TAT). Depending on the analyzed cell lines, the used activity concentrations and specific activities (MBq/μg antibody) apoptosis was induced abrogating radio- and chemo-cross-resistances specifically. The cell death was caspase-dependent activating the mitochondrial pathway and was executed by downregulation of the anti-apoptotic proteins XIAP and Bcl-xL. D,L-Methadone induces apoptosis in vitro and in vivo in opioid-receptor (OR) expressing cells depending on the OR density and the used concentrations. Resistances could be overcome and proliferation was inhibited. In combination with doxorubicin, a synergistic effect regarding cytotoxicity in ex vivo patient cells and cell lines was observed. This effect depends on the increase of doxorubicin uptake co-administering D,L-methadone whereas doxorubicin enhances OR expression. The activation of OR leads to the downregulation of cAMP playing a pivotal role in apoptosis induction. In vivo, the therapeutic potential of D,L-methadone alone or in combination with doxorubicin could be proven as mice transplanted with human T-ALL-cells could be identified as tumour free. In summary, these studies show that TAT using [Bi-213]anti-CD33 and [Bi-213]anti-CD20 as well as the opioid D,L-methadone harbour the potential to optimize conventional treatment modalities for leukaemia and NHL.

    Full Text Available Abstract Background survivors of non-Hodgkin's lymphoma (NHL are well known to be at an increased risk of second malignancies. In this study, we evaluated the incidence and clinical features of head and neck cancer (HNC occurring after radiotherapy (RT for NHL. Materials and methods We investigated the clinical records of 322 patients who had received RT for early-stage NHL of the head and neck at our institute between 1952 and 2000. Results There were 4 patients with a second HNC developing in the irradiated field, consisting of 2 patients with gum cancer, 1 case with tongue cancer and 1 case with maxillary sinus cancer. The pathological diagnosis in all the 4 patients was squamous cell carcinoma (SCC. Two of the patients (one with gum cancer and one with maxillary sinus cancer died of the second HNC, while the remaining 2 patients are still living at the time of writing after therapy for the second HNC, with neither recurrence of the second tumor nor relapse of the primary tumor. The ratio of the observed to the expected number (O/E ratio of a second HNC was calculated to be 12.7 (95%CI, 4.07–35.0, and the absolute excess risk (AER per 10,000 person-years was 13.3. The median interval between the RT and the diagnosis of the second HNC was 17.0 years (range, 8.7 to 22.7 years. Conlusion The risk of HNC significantly increased after RT for early-stage NHL. These results suggest that second HNC can be regarded as one of the late complications of RT for NHL of the head and neck.

    Mutation analysis of FBXW7 and NOTCH1 genes was performed in 55 T cell acute lymphoblastic leukaemia (T-ALL) and 14 T cell non-Hodgkin lymphoma (T-NHL) patients who were treated on the Japan Association of Childhood Leukaemia Study (JACLS) protocols ALL-97 and NHL-98. FBXW7 and/or NOTCH1 mutations were found in 22 (40.0%) of 55 T-ALL and 7 (50.0%) of 14 T-NHL patients. FBXW7 mutations were found in 8 (14.6%) of 55 T-ALL and 3 (21.4%) of 14 T-NHL patients, and NOTCH1 mutations in 17 (30.9%) of 55 T-ALL and 6 (42.9%) of 14 T-NHL patients. Three (5.4%) T-ALL and two (1.4%) T-NHL patients had mutations in both FBXW7 and NOTCH1. FBXW7 mutations included one insertion, one deletion, one deletion/insertion and nine missense mutations. NOTCH1 mutations were detected in the heterodimerization domain (HD) in 15 cases, in the PEST domain in seven cases, and in both the HD and PEST domains in one case. Five-year event-free survival and overall survival for patients with FBXW7 and/or NOTCH1 mutations were 95.5% (95% CI, 71.9-99.4%) and 100% respectively, suggesting that T-ALL patients with FBXW7 and/or NOTCH1 mutation represent a good prognosis compared to those without FBXW7 and/or NOTCH1 mutations (63.6%, P = 0.007 and 78.8%, P = 0.023, respectively).

    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.

    The objective of this study is to describe the most recent geographical patterns of incidence of AIDS-related cancers, Kaposi's sarcoma (KS), nonHodgkin lymphoma (NHL), and cervical cancer in North African and subSaharan African populations. Data were extracted for the period 1998-2002 from five African population-based cancer registries: Kyadondo, Harare, Setif, Sousse, and Gharbiah. Age-standardized rates were calculated using the African standard population; a comparison was made between these populations by computing the standardized incidence ratio and 95% confidence intervals. The KS rate was found to be significantly higher in men than in women, and higher in Harare (women: 26.3/100,000; men: 50.4/100,000) and Kyadondo (women: 23.6/100,000; men: 30.2/100,000) than in the North African sites for both sexes (HIV/AIDS (15-49 years), and these rates were 4.5-fold higher in subSaharan populations than those in the North African sites. Thus, it was observed that the pattern of HIV prevalence is variable with the lowest prevalence in North African countries, intermediate prevalence in Uganda, and the highest prevalence in Zimbabwe. Our findings show that the incidence of NHL and cervical cancer, considered to be HIV/AIDS-related cancers, does not follow the pattern of HIV prevalence in the five studied African populations. Thus, the highest NHL incidence rate in both sexes in Gambia may be explained, at least in great part, by the highest hepatitis C virus prevalence observed there. Indeed, factors other than HIV infection likely contribute to their geographical patterns.

    Rituximab was the first chimeric monoclonal antibody to be approved for treatment of indolent B-cell non-Hodgkin's lymphoma (NHL). It is directed against the CD20 antigen, which is expressed by 95% of B-cell NHLs. The aim of this study was to explore the possibility of radiolabelling rituximab with 99m Tc for use as an imaging agent in NHL for early detection, staging, remission assessment, monitoring for metastatic spread and tumour recurrence, and assessment of CD20 expression prior to (radio)immunotherapy. Rituximab was purified from Mabthera solution (Roche), photo-activated at 302 nm by UV irradiation and radiolabelled with 99m Tc. The effectiveness of the labelling method was evaluated by determination of the number of free thiol groups per photoreduced antibody, radiochemical purity and in vitro stability of 99m Tc-rituximab. On average, 4.4 free thiol groups per photoreduced antibody were determined. Radiolabelling yields greater than 95% were routinely observed after storage of the photo-activated antibody at -80 C for 195 days. The direct binding assay showed preserved ability of 99m Tc-rituximab to bind to CD20, with an average immunoreactive fraction of 93.3%. The internalisation rate was proven to be low, with only 5.3% of bound 99m Tc-rituximab being internalised over 4 h at 37 C. Our results demonstrate that 99m Tc-rituximab of high radiochemical purity and with preserved binding affinity for the antigen can be prepared by photoreduction and that the method shows good reproducibility. 99m Tc-rituximab will be further explored as an imaging agent applicable in NHL for the purposes mentioned above.

    We evaluated the occurrence of second cancers among 517 patients with non-Hodgkin's lymphoma (NHL) treated at the National Cancer Institute. Nine cases of acute nonlymphocytic leukemia (ANL) were observed compared to 0.08 cases expected (ratio of observed to expected cases, 105; 95% confidence limits, 48; 199). The excess risk of ANL was 4.1 cases per 1000 patients per year; the cumulative risk of ANL at 10 years was 7.9 +/- 3.2% (S.E.). A case-control study within the NHL cohort revealed that patients treated with both radiation and chemotherapy were at greater risk of ANL than were patients who received single-modality therapy (relative risk, 6.0; p less than 0.05), especially if the therapy included total-body or hemibody radiation. A positive correlation between cumulative radiation dose to the bone marrow and risk of ANL was demonstrated, independent of chemotherapy duration. A similar correlation between chemotherapy dose and risk of ANL was suggested but could not be proven with the available data. An apparent association between ANL risk and indolent NHL histological subtypes was due to the significantly larger amounts of potentially leukemogenic therapy to which these patients were repeatedly exposed. Only one case of ANL occurred among NHL patients whose initial therapy produced a durable complete remission. Our data are compatible with a multistep model of leukemogenesis and also underscore the need for curative NHL treatment regimens which minimize the duration and quantity of therapy required for optimum patient management

    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

    The results of 2 consecutive and prospective trials with specifically devised chemotherapy regimens in elderly patients (pts) with non-Hodgkin's lymphoma (NHL) are reported. Between August 1979 and September 1984, 66 pts aged 70 or older (median 75 years) with NHL entered 2 consecutive trials, the former with single agent teniposide 100 mg/m2 i.v. weekly (41 pts), the latter with etoposide and prednimustine (E + P), 100 mg/m p.o. for 5 days every 21 days (25 pts). Forty-five pts were previously untreated, 21 previously treated. Forty-seven pts were of the intermediate and high grade groups according to the Working Formulation; 19 pts were of the low grade; 57 pts were stages III and IV, 9 pts were stages I and II. The median performance status was 70 (range 30-100). The objective response rate in the 66 evaluable pts is 53% with 38% CR; the 3-year overall, disease-free and CR survivals are 21, 12 and 40% respectively. The objective response rate in the 45 previously untreated pts is 58% with 42% CR; the 3-year overall, disease-free and CR survivals are 24, 16 and 58% respectively. The overall toxicity was mild. Severe toxicity (grade III and IV according to WHO criteria) was observed only in 16/498 courses (3.2%), with 1 toxic death (grade IV leucopenia). We experienced the usefulness of a properly orientated clinical approach to elderly pts with NHL. We suggest that a combination regimen like E + P, suitable for oral administration, may be safely employed in a large fraction of pts with NHL.

    Full Text Available Non-Hodgkin lymphoma (NHL is a frequent cancer and incidence rates have increased markedly during the second half of the 20(th 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.

    Radioimmunotherapy (RIT) uses target-specific monoclonal antibodies or fragments labeled with a radioactive isotope to combine humoral and radiolytic functions and has the advantage of targeting not only the cell to which the antibody is bound but also the surrounding tumor cells and microenvironment. The most successful clinical studies of RIT in patients with Non-Hodgkin's Lymphoma (NHL) have targeted CD20+ Bcell tumors. Antibody therapy directed against the CD20 antigen on the surface of B-cells is considered one of the first successful target-specific therapies in oncology. The radionuclide rhenium-188 ( 188 Re) is currently produced from the father nuclide 188 W through a transportable generator system. Because of its easy availability and suitable nuclear properties (E βMAX = 2.1 MeV, t1/2 = 16.9 h, E γ = 155 keV), this radionuclide is considered an attractive candidate for application as therapeutic agent and could be conveniently utilized for imaging and dosimetric purposes. The objective of this work is the optimization of direct radiolabeling method of anti-CD20 with 188 Re using a liquid formulation. Anti-CD20 was reduced by incubation with 2-mercaptoethanol at room temperature. The number of resulting free sulphydryl groups was assayed with Ellman's reagent. Optimization of radiolabeling was achieved by varying parameters: antibody mass, reducing agent mass, tartrate mass, stability and reaction time, 188 Re volume and activity. Radiochemical purity of 188 Re-anti-CD20 was evaluated using instant thin layer chromatography-silica gel (ITLC-SG). Quality control methods for evaluation of radiochemical purity showed good labeling yield of the antibody but further studies will be carried out in order to improve the labeling yields and consequently the specific activity of the product.

    Several randomised comparative trials have shown that granulocyte colony-stimulating factor (G-CSF) reduces the duration of neutropenia, hospitalisation and intravenous antibacterial use in patients with cancer who are receiving high-dosage antineoplastic therapy. However, one area that has received less attention is the role of G-CSF in standard-dosage antineoplastic regimens. One such treatment that is considered to have a low potential for inducing fever and neutropenia is the CHOP regimen (cyclophosphamide, doxorubicin, vincristine and prednisone) for non-Hodgkin's lymphoma. We conducted a cost-benefit analysis from a societal perspective in order to estimate the net cost or benefit of prophylactic G-CSF in this patient population. This included direct costs for hospitalisation with antibacterial support, as well as indirect societal costs, such as time off work and antineoplastic therapy delays secondary to neutropenia. The findings were then tested by a comprehensive sensitivity analysis. The administration of G-CSF at a dosage of 5 micrograms/kg/day for 11 doses following CHOP resulted in an overall net cost of $Can1257. In the sensitivity analysis, lowering the G-CSF dosage to 2 micrograms/kg/day generated a net benefit of $Can6564, indicating a situation that was cost saving to society. The results of the current study suggest that the use of G-CSF in patients receiving CHOP antineoplastic therapy produces a situation that is close to achieving cost neutrality. However, low-dosage (2 micrograms/kg/day) G-CSF is an economically attractive treatment strategy because it may result in overall savings to society.

    The addition of rituximab to doxorubicin-containing standard chemotherapy significantly improves response to therapy and reduces the risk of death in B-cell non-Hodgkin's lymphoma (NHL) patients. However, the impact of this approach on doxorubicin-induced cardiotoxicity has not been elucidated. Patients who had been planned to receive CHOP or rituximab plus CHOP (R-CHOP) combination chemotherapy with a diagnosis of NHL were included in the study. In all patients, systolic and diastolic parameters were measured by using conventional and pulsed-wave tissue Doppler echocardiography, which is more sensitive than conventional lead-dependent techniques, both before and in the sixth month of therapy. There were 28 (M/F; 14/14) patients on CHOP and 33 (M/F; 16/17) patients on R-CHOP. Median age in CHOP and R-CHOP was 49 and 50 years (P = 0.44), respectively. Cumulative doxorubicin doses were 280 and 286 mg/m(2) on CHOP and R-CHOP (P = 0.65), respectively. None of the patients developed clinically evident congestive heart failure. Parameters of systolic function such as LVEF and FS did not significantly change in any patients. In both arms, tissue Doppler parameters of diastolic function such as lateral E and septal E velocity of mitral annulus decreased significantly after therapy (P 0.05). Conventional Doppler echocardiography yielded consistent findings. Both CHOP and R-CHOP cause diastolic dysfunction in the early period following their administration. The addition of rituximab to CHOP chemotherapy does not significantly increase the risk of doxorubicin-induced cardiotoxicity during this period.

    We have reviewed 37 patients with primary orbital lymphoma, using the Ann Arbor criteria and the Working Formulation and its modification. Thirty-one patients had stage I disease, four stage II, one stage III and one stage IV. The male to female ratio was 2.7:1. There were 34 low-grade tumours (including 24 mantle zone) and three intermediate-grade. Patients were divided into three groups according to their primary treatment. Group 1: radiotherapy (17 cases); Group 2: surgery alone (13 cases); Group 3: chemotherapy (seven cases). Patients were followed up from 5 months to 24.3 years, with a mean and median of 7.6 and 6.2 years, respectively. The BMDP software package was used for survival estimation (Kaplan-Meier) and determination of prognostic variable (univariate Cox regression). Local relapse-free survival at 10 years was 100% in Group 1, 0% in Group 2 and 42% in Group 3 with a statistically significant difference (p < 0.01) in favour of radiotherapy. Statistically significant good prognostic features were: complete remission (CR) in response to initial treatment, primary radiotherapy and older age. For stage I cases, there was no difference in distant relapse-free survival in the three groups. The overall cause-specific survival for stage I patients at 10 years was 100% for each group and at 20 years was 100, 67 and 0% for Group 1, 2 and 3. The difference between the primary radiotherapy and chemotherapy-treated groups was significant at the p = 0.08 level. Statistically significant prognostic factors were early stage, low-grade histology and primary radiotherapy. In one patient, ptosis and diplopia appeared after surgery. One case of glaucoma required enucleation, one patient suffered severe dry eye syndrome. All patients ((11(11))) in whom the lens received direct radiation developed cataracts of different degrees if follow-up was long enough. Cataract formation was prevented by adequate lens shielding. One patient in CR from a stage I low-grade tumour died

    Full Text Available Angiogenesis and lymphangiogenesis are important in the proliferation and survival of the malignant hematopoietic neoplasms, including non-Hodgkin’s lymphomas (NHLs. Vascular endothelial growth factor (VEGF and basic fibroblast growth factor (bFGF play an important role in the initiation of angiogenesis. Both VEGF and bFGF have been reported to have prognostic significance in NHL. The present study aimed to determine an association between the VEGF and bFGF gene polymorphisms and disease susceptibility and progression. VEGF (rs3025039; 936 C>T and bFGF (rs308395, −921 G>C variants were determined in 78 NHL patients and 122 healthy individuals by PCR-RFLP technique. The presence of the VEGF 936T allele was found to significantly associate with worse prognosis of the disease (expressed by the highest International Prognostic Index (IPI (0.41 versus 0.20, for IPI 4 among patients having and lacking the T allele. The VEGF 936T variant was also more frequent among patients with IPI 4 than in controls (OR = 3.37, . The bFGF −921G variant was more frequently detected among patients with aggressive as compared to those with indolent histological subtype (0.37 versus 0.18, and healthy individuals (0.37 versus 0.19, OR = 2.51, . These results imply that VEGF and bFGF gene polymorphisms have prognostic significance in patients with NHL.

    We present a 74-year-old male with nonspecific interstitial pneumonia (NSIP) during treatment with ibrutinib for mantle cell lymphoma. Previously, the patient had received six cycles of bendamustine and rituximab and six cycles of R-CHOP, followed by rituximab maintenance therapy. Respiratory tract complications of ibrutinib other than infectious pneumonia have not been mentioned in larger trials, but individual case reports hinted to a possible association with the development of pneumonitis. In our patient, the onset of alveolitis that progressed towards NSIP together with the onset of ibrutinib treatment suggests causality. One week after ibrutinib was discontinued, nasal symptoms resolved first. A follow-up CT showed a reduction in the reticular hyperdensities and ground-glass opacities, suggestive of restitution of the lung disease. To our knowledge, this is the first case showing a strong link between ibrutinib and interstitial lung disease, strengthening a previous report on subacute pneumonitis. Our findings have clinical implications because pulmonary side effects were reversible at this early stage. We, therefore, suggest close monitoring for respiratory side effects in patients receiving ibrutinib.

    Full Text Available BACKGROUND: Although multimodality treatment can induce high rate of remission in many subtypes of non-Hodgkin's lymphoma (NHL, significant proportions of patients relapse with incurable disease. The effect of human bone marrow (BM mesenchymal stem cells (MSC on tumor cell growth is controversial, and no specific information is available on the effect of BM-MSC on NHL. METHODOLOGY/PRINCIPAL FINDINGS: The effect of BM-MSC was analyzed in two in vivo models of disseminated non-Hodgkin's lymphomas with an indolent (EBV(- Burkitt-type BJAB, median survival = 46 days and an aggressive (EBV(+ B lymphoblastoid SKW6.4, median survival = 27 days behavior in nude-SCID mice. Intra-peritoneal (i.p. injection of MSC (4 days after i.p. injection of lymphoma cells significantly increased the overall survival at an optimal MSC:lymphoma ratio of 1:10 in both xenograft models (BJAB+MSC, median survival = 58.5 days; SKW6.4+MSC, median survival = 40 days. Upon MSC injection, i.p. tumor masses developed more slowly and, at the histopathological observation, exhibited a massive stromal infiltration coupled to extensive intra-tumor necrosis. In in vitro experiments, we found that: i MSC/lymphoma co-cultures modestly affected lymphoma cell survival and were characterized by increased release of pro-angiogenic cytokines with respect to the MSC, or lymphoma, cultures; ii MSC induce the migration of endothelial cells in transwell assays, but promoted endothelial cell apoptosis in direct MSC/endothelial cell co-cultures. CONCLUSIONS/SIGNIFICANCE: Our data demonstrate that BM-MSC exhibit anti-lymphoma activity in two distinct xenograft SCID mouse models of disseminated NHL.

    Extranodal NK/T-cell lymphoma, nasal type (ENKTL-NT) is an aggressive extranodal non-Hodgkin lymphoma most commonly occurring in East Asia and Latin America but with increasing incidence in the U.S. Data on epidemiology, disease presentation, and outcome for European and North American (“Western”) cases are very limited. We review published landmark clinical studies on ENKTL-NT in the West and report in detail recent data, including our institutional experience. We highlight key observations in its epidemiology, natural history, and trends in clinical management. In the U.S., ENKTL-NT is more common among Asian Pacific Islanders (API) and Hispanics compared to non-Hispanic whites. Published studies indicate less heterogeneity in clinical presentation in Western ENKTL-NT compared to Asian patients. While there is variation in age at diagnosis, presence of antecedent lymphoproliferative disorders, and outcomes among racial/ethnic groups, the universal association of ENKTL-NT with EBV and the poor response of this neoplasm to anthracycline-based therapy are consistent across all geographic areas.

    The aim of this retrospective study was to define the natural history, clinicopathological findings, prognostic factors, and treatment outcome of 43 patients with localized stages I and II primary non-Hodgkin's lymphoma (NHL) of the nasopharynx, followed up in a single institution over a 17-year period. Forty-three (13 women and 30 men) consecutive patients with localized stages I (N = 12) and II (N = 31) primary nasopharyngeal NHL were treated in our institution between 1990 and 2007. The pathologic reports were classified according to the International Working Formulation (N = 22) or Revised European-American Lymphoma classification (N = 21). The vast majority of patients (88%) were managed with a sequential combination of chemotherapy and radiation therapy. Chemotherapy mainly consisted of 4-8 (median 6) cycles of CHOP regimen (cyclophosphamide, doxorubicin, vincristine and prednisolone). Involved-field radiation therapy with a median dose of 44 Gy was delivered to the primary site and entire cervical lymph nodes. The median age of the patients was 53 years (range, 6 to 86 years). The majority of the patients (70%) had high-grade histology. B-cell types represented 67% of the cases, among which diffuse large B cell was the most common histological subtype. After a median follow-up of 70 months, the 5-year disease-free survival and overall survival were 58.8% and 70.6%, respectively. In multivariate analysis, age less than or equal to 30 years (hazard ratio (HR) = 5.32, 95% confidence interval (CI) = 1.69-16.76), elevated serum lactate dehydrogenase level (HR = 3.69, 95% CI = 1.43-9.51), and modified International Prognostic Index with more than or equal to two risk factors (HR = 17.99, 95% CI = 2.32-139.30) retained statistical significance. Our limited data suggest that primary nasopharyngeal NHL tends to have aggressive histology and unfavorable clinical course with poor outcome, despite a considerably localized disease at the time of presentation and high

    Yin Yang 1 (YY1) is a transcription factor that plays an important role during all stages of B cell differentiation. Several studies reported upregulation of YY1 in B cell derived lymphoma, indicating that it might act as an oncogene. Furthermore, aberrant YY1 expression has been associated with survival in some entities of B cell non-Hodgkin lymphoma (B-NHL), suggesting that YY1 could be a valuable biomarker in B-NHL. However, studies are controversial and methodologically disparate, partially because some studies are based on transcript levels while others rely on YY1 protein data. Therefore, we aimed to investigate the dependence of YY1 protein levels on YY1 transcription. A panel of human cell lines representing different B-NHL subtypes was used to test for the correlation of YY1 mRNA and protein levels which were determined by quantitative PCR and immunoblotting. To analyze YY1 mRNA and YY1 protein stability cells were treated with actinomycin-D and cycloheximide, respectively. siRNAs were transfected to knockdown YY1 . Kaplan-Meier survival analyses were performed with data from published patient cohorts. Pearson's correlation analyses were assessed and statistical power was examined by Student's t-test. In the analyzed panel of B-NHL cell lines YY1 transcript levels do not correlate with their cellular protein amounts. YY1 protein levels were unaffected by transient block of transcription or by targeting YY1 mRNA using siRNA. Additionally, global inhibition of translation up to 48 h did not alter protein levels of YY1, indicating that YY1 is a highly stable protein in B-NHL. Furthermore, in a retrospective analysis of two different B-NHL cohorts, YY1 transcript levels had no impact on patients' survival probabilities. Our results point out the necessity to focus on YY1 protein expression to understand the potential role of YY1 as an oncogene and to unravel its suitability as clinical biomarker in B-NHL.

    Full Text Available Background: Malignant lymphomas arising in extranodal sites are intriguing. The histological types of lymphomas vary from one site to another. This study is undertaken to diagnose and categorize extranodal lymphomas using histochemistry and immunohistochemistry (IHC. Materials and Methods: Formalin processed paraffin blocks and hematoxylin and eosin stained sections were used for routine histology. IHC was done in all cases. Results: We have encountered 31 cases of extra nodal lymphomas over a period of 3 years. The tumors occurred at different sites, including brain, nasopharynx, nose, gastrointestinal tract, thyroid, bone, testis, breast, lung, vagina, and skin. Majority of the cases were B-cell lymphomas, while four cases were T-cell lymphomas. Among the B-cell lymphomas diffuse large B-cell lymphoma was the most common variant. Conclusion: This study reiterates the key role of IHC particularly when the differential diagnosis includes an undifferentiated epithelial malignancy and a high-grade lymphoma in the extranodal sites as the treatment modalities and prognosis are different.

    Extranodal involvement is a well-known prognostic factor in patients with diffuse large B-cell lymphomas (DLBCL). Nevertheless, the prognostic impact of the extranodal scoring system included in the conventional international prognostic index (IPI) has been questioned in an era where rituximab treatment has become widespread. We investigated the prognostic impacts of individual sites of extranodal involvement in 761 patients with DLBCL who received rituximab-based chemoimmunotherapy. Subsequently, we established a new extranodal scoring system based on extranodal sites, showing significant prognostic correlation, and compared this system with conventional scoring systems, such as the IPI and the National Comprehensive Cancer Network-IPI (NCCN-IPI). An internal validation procedure, using bootstrapped samples, was also performed for both univariate and multivariate models. Using multivariate analysis with a backward variable selection, we found nine extranodal sites (the liver, lung, spleen, central nervous system, bone marrow, kidney, skin, adrenal glands, and peritoneum) that remained significant for use in the final model. Our newly established extranodal scoring system, based on these sites, was better correlated with patient survival than standard scoring systems, such as the IPI and the NCCN-IPI. Internal validation by bootstrapping demonstrated an improvement in model performance of our modified extranodal scoring system. Our new extranodal scoring system, based on the prognostically relevant sites, may improve the performance of conventional prognostic models of DLBCL in the rituximab era and warrants further external validation using large study populations.

Solid areas in the background of the non-structural gel are established, hardly to be distinguished from primary mammary lesions. At a control US examination 6 months after the surgical intervention, an increase in new l.n. in the right axilla is established. The biopsy performed discovered the histological features for follicular non-Hodgkin's lymphoma grade 2, CD 20 (+) sex. The links of the lymphoma as a systemic manifestation of the local cytotoxic effect in the C-myc gene expression of the medical polyacrylamide hydrogel is questionable. In all women after Augmentation Mammoplasty with PAAG 6-month follow-ups with US are recommended, completed with MRI if needed and, annual blood tests as well. For equivocal clinical examinations and imaging studies, proceed to a FNB or Cor biopsy under US control. Key words: Mastitis. Augmentation MAMMOPLASTY. PAAG, US. MRT.

    7 children suffering from acute lymphatic leukemia (ALL) and non-Hodgkin's lymphoma, resp., were injected intrathecally with /sup 198/Au colloid for metaphylaxis. The children had been cured of 8 relapses of miningosis and received irregularly intrathecal injections of methotrexate for cerebral maintenance therapy. The median cerebral period of remission was 52 weeks. 1 child suffering from ALL had been free from meningosis relapses for 128 weeks. Continuous cytostatic therapy is necessary for methaphylaxis. However, despite of the good results presented, /sup 198/Au colloid can not be recommended for long-term therapy because radiation injuries are to be expected.

    Immunohistochemistry (IHC) is frequently used to detect plasma cell (PC) or B cell monoclonality in histologic sections, but its interpretation is often confounded by background staining. We evaluated a new automated method for colorimetric in situ hybridization (CISH) detection of clonality in PC dyscrasias and small B cell lymphomas. Cases of PC dyscrasia included multiple myeloma (MM; 31 cases), plasmacytoma (seven cases), or amyloidosis (one case), while cases of lymphoma included small lymphocytic (three cases), marginal zone (four cases), lymphoplasmacytic (three cases), and mantle cell lymphomas (three cases). Tissue sections were stained for kappa and lambda light chains by IHC and for light chain mRNA by automated CISH using haptenated probes. Twenty-eight of 31 MM cases had detectable light chain restriction by IHC. Thirty of 31 MM cases demonstrated light chain restriction by CISH, including 2 cases with uninterpretable IHC and one case of nonsecretory myeloma, which was negative for light chains by IHC. Seven of 7 plasmacytoma cases had detectable light chain restriction by CISH, including one case of nonsecretory plasmacytoma in which IHC was noninformative. Automated CISH demonstrated monoclonality in 9 of 13 cases of B cell non-Hodgkin lymphoma and had a slightly higher sensitivity than IHC (6 of 13 cases), especially in cases of lymphoplasmacytic and marginal zone lymphoma. Overall, there were no discrepancies in light chain restriction results between IHC, CISH, or serum paraprotein analysis. Automated CISH is useful in detecting light chain expression in paraffin sections and appeared superior to IHC for light chain detection in PC dyscrasias and B cell non-Hodgkin lymphomas, predominantly due to lack of background staining.

    The treatment of lymphoma, both Hodgkin as non-Hodgkin, has had irradiation as part of management. The neck and/or mediastinum is irradiated and occurs, inevitably, partial or total irradiation of the thyroid gland. The evaluation that the effect may have on the function of the gland has been the purpose of this study. The risk of hypothyroidism in patients with Hodgkin lymphoma and non-Hodgkin should receive radiation therapy to the head, neck and/or mediastinum was studied. This has represented a first report of a follow-up study, of 2 years, analytical, longitudinal, observational, prospective. This is a first report of a follow-up study, of 2 years, analytical, longitudinal, observational, prospective. Design of cases, controls and a sample of 32 patients were studied; of these 31.25% have developed subclinical hypothyroidism. The subgroup with hypothyroidism was studied and an association was found between thyroid failure and dose, including the possibility of reversion of disorders. Association with the type of lymphoma and received chemotherapy was found, while with age, sex, lymphoma staging and dose received by the lymphoma is found without association. The onset of subclinical hypothyroidism generated by irradiation of the neck and/or mediastinum is associated with the radiation dose received by the thyroid. A relationship, unclear, has existed between the type of lymphoma and chemotherapy indicated as a treatment and should be explored further, a routine basis indicating the evaluation of the thyroid function in all these patients to avoid the development of unmonitored disorders.

    To describe the behavior and variability of methotrexate (MTX) pharmacokinetic parameters in patients with non-Hodgkin lymphoma (NHL) and to suggest a monitoring system to optimize sample collection using a bayesian method. Two adult patient groups diagnosed with different NHL types were studied. Group I was made up of 9 patients aged 53 +/- 16 years who received MTX at a mean dose of 1.652 +/- 327 mg per course. Group II was made up of 7 patients aged 53 +/- 14 years who received MTX at a mean dose of 1.862 +/- 220 mg per course. No statistically significant differences between groups were seen. Serum MTX measurements were performed using polarized immunofluorescence (TDx system). The pharmacokinetic analysis was performed using Abbottbase Pharmacokinetics Systems (PKS) software, adjusting experimental data according to a bicompartmental linear model for intravenous delivery using non-linear regression in Group I and Bayesian estimates in Group II. By estimating mean square error and linear regression between predicted and experimental concentrations, the capability of the Bayesian method implemented in PKS to predict plasma MTX concentration at 48 hours post-infusion was evaluated. The safety of MTX therapy was assessed using patient medical histories and then scoring toxicity using the WHO scale. Pharmacokinetic parameters obtained for group I included: alpha (h(-1)) = 0.38 +/- 0.12; beta (h(-1)) = 0.07 +/- 0.03; K12 (h(-1)) = 0.02 +/- 0.02; K21 (h(-1)) = 0.09 +/- 0.09; K13 (h(-1)) = 0.34 +/- 0.12; Vc (l/kg) = 0.53 +/- 0.23; Vss (l/kg) = 0.62 +/- 0.26; Cl (l/kg.h) = 0.16 +/- 0.06. The error for the PKS population model in measuring plasma MTX concentration at 48 hours post-infusion in Group II was calculated in accordance with three sampling schemes -12 h, 24 h, and both. It was -14.58 x 10(-3), -15.70 x 10(-3) and -14.67 x 10(-3), respectively. Eqm was 9.58 x 10(-3), 2.39 x 10(-3), and 1.02 x 10(-3), respectively. An MTX monitoring scheme is suggested based on

    Purpose: To evaluate the response rate (RR) and time to local recurrence (TTLR) among patients who received salvage radiation therapy for relapsed or refractory aggressive non-Hodgkin lymphoma (NHL) and investigate whether RR and TTLR differed according to disease characteristics. Methods and Materials: A retrospective review was performed for all patients who completed a course of salvage radiation therapy between January 2001 and May 2011 at Brigham and Women's Hospital/Dana-Farber Cancer Institute. Separate analyses were conducted for patients treated with palliative and curative intent. Predictors of RR for each subgroup were assessed using a generalized estimating equation model. For patients treated with curative intent, local control (LC) and progression-free survival were estimated with the Kaplan-Meier method; predictors for TTLR were evaluated using a Cox proportional hazards regression model. Results: Salvage radiation therapy was used to treat 110 patients to 121 sites (76 curative, 45 palliative). Salvage radiation therapy was given as part of consolidation in 18% of patients treated with curative intent. Median dose was 37.8 Gy, with 58% and 36% of curative and palliative patients, respectively, receiving 39.6 Gy or higher. The RR was high (86% curative, 84% palliative). With a median follow-up of 4.8 years among living patients, 5-year LC and progression-free survival for curative patients were 66% and 34%, respectively. Refractory disease (hazard ratio 3.3; P=.024) and lack of response to initial chemotherapy (hazard ratio 4.3; P=.007) but not dose (P=.93) were associated with shorter TTLR. Despite doses of 39.6 Gy or higher, 2-year LC was only 61% for definitive patients with refractory disease or disease that did not respond to initial chemotherapy. Conclusions: Relapsed or refractory aggressive NHL is responsive to salvage radiation therapy, and durable LC can be achieved in some cases. However, refractory disease is associated with a

    Angioimmunoblastic T cell lymphoma (AITL) is a peripheral T cell non-Hodgkin lymphoma with an aggressive fatal course and it has varied clinical presentation with an uncommon presentation when they present as soft tissue masses or when there is spill in the peripheral blood or there are composite lymphomas that are rare presentations. Common presentations include lymphadenopathy, fever and systemic symptoms, hemolytic anemias, skin rashes, and rheumatoid arthritis. The classical histopathology is absence of follicles in lymph nodes with presence of high endothelial venules and the tumor cells of small to medium-sized lymphocytes with pale cytoplasm mixed with reactive T cells. On immunohistochemistry, the cells are positive for CD3, CD4, CD10, BCL2, and CXCL13. In this observational study, the clinicopathologic presentation and the immunohistochemical profile of five cases who initially presented with a soft tissue mass which is an extremely rare presentation of this rare type of non-Hodgkin lymphoma that was diagnosed at our center with peripheral blood and bone marrow involvement and the clinicopathologic presentation, immunohistochemical profile, and response to treatment on follow-up are correlated with the literature review. One case had a fulminant and aggressive course and was fatal within 2 months of diagnosis. The rest of the four cases are on regular chemotherapy and follow-up. Our five cases had presented with soft tissue masses, two in the axillary regio,n two in the hand, and one in the scapular region with an extranodal presentation, and there was associated lymphadenopathy which developed subsequently with classic histomorphology and immunohistochemical findings. The age range was 46-54 years and all five cases were males. Three cases were with anemia (hemoglobin range 6.5-8.0 mg/dl) and all five cases were having peripheral blood plasmacytosis. Histopathology was classic with paracortical involvement with polymorphous population of cells with

    Purpose/Objective: To assess local (in-field) disease control, identify potential prognostic factors, and elucidate the optimal radiotherapy dose in various clinical settings of Stage I and II nonHodgkin's lymphoma (non-CNS). Materials and Methods: A total of 285 consecutive patients with Stage I and II non-Hodgkin's lymphoma were treated with curative intent, including 159 with radiotherapy (RT) alone and 126 with combined-modality therapy (CMT). Of these, 72 patients had low-grade lymphomas (LGL), 92 had intermediate or high-grade lymphomas (I/HGL), and 21 had unclassified lymphomas. Clinical and treatment variables with potential prognostic significance for in-field disease control, freedom from relapse (FFR), and absolute survival (AS) were evaluated by univariate and multivariate analyses. Results: The 5-, 10-, and 20-year actuarial AS rates were 73%, 46%, and 33% for patients with LGL and 64%, 44%, and 18% for patients with I/HGL, respectively. The 5-, 10-, and 20-year actuarial FFR rates were 62%, 59%, and 49% for patients with LGL and 66%, 57%, and 57% for patients with I/HGL, respectively. Significant prognostic factors identified by the multivariate analysis were age, tumor size, and histology for AS; tumor size and treatment for FFR; and only tumor size for in-field disease control. There were 95 total failures, with only 12 occurring infield. Most failures (65%) were in contiguous unirradiated sites. All 4 in-field failures in patients with LGL occurred after RT doses 6 cm, and 4 with less than a complete response (CR) to chemotherapy. Conclusion: Our analysis suggests that the overwhelming problem in the treatment of non-Hodgkin's lymphoma is not in-field failure but, rather, failure in contiguous unirradiated sites. A dose of 20-25 Gy may be sufficient for small-volume LGL of the orbit. A dose of 30 Gy is sufficient for LGL in general, as well as for patients with nonbulky (≤ 6 cm) I/HGL treated with CMT who have a CR. However, patients with I

    Full Text Available Extranodal NK/T-cell lymphoma (ENKTCL is a highly aggressive mature NK/T-cell neoplasm marked by NK-cell phenotypic expression of CD3ε and CD56. While the disease is reported worldwide, there is a significant geographic variation with its highest incidence in East Asian countries possibly related to the frequent early childhood exposure of Epstein–Barr virus (EBV and specific ethnic–genetical background, which contributes to the tumorigenesis. Historically, anthracycline-based chemotherapy such as CHOP (cyclophosphamide, adriamycin, vincristine, and prednisone was used, but resulted in poor outcomes. This is due in part to intrinsic ENKTCL resistance to anthracycline caused by high expression levels of P-glycoprotein. The recent application of combined modality therapy with concurrent or sequential radiation therapy for early stage disease, along with non-anthracycline-based chemotherapy regimens consisting of drugs independent of P-glycoprotein have significantly improved clinical outcomes. Particularly, this neoplasm shows high sensitivity to l-asparaginase as NK-cells lack asparagine synthase activity. Even still, outcomes of patients with advanced stage disease or those with relapsed/recurrent disease are dismal with overall survival of generally a few months. Thus, novel therapies are needed for this population. Clinical activity of targeted antibodies along with antibody–drug conjugates, such as daratumumab (naked anti-CD38 antibody and brentuximab vedotin (anti-CD30 antibody conjugated with auristatin E, have been reported. Further promising data have been shown with checkpoint inhibitors as high levels of programmed death-ligand 1 expression are observed in ENKTCL due to EBV-driven overexpression of the latent membrane proteins [latent membrane protein 1 (LMP1 and LMP2] with activation of the NF-κB/MAPK pathways. Initial case series with programmed death 1 inhibitors showed an overall response rate of 100% in seven relapsed

    Full Text Available Abstract Background In the last years human proteomic has represented a promising tool to promote the communication between basic and clinical science. Methods To explore the correspondence between salivary proteomic profile and clinical response, herein, we used a proteomic approach to analyse the whole saliva of a patient with primary Sjögren's Syndrome (pSS and non-Hodgkin's-MALT type parotid lymphoma before, during and after a standard treatment with cyclophosphamide (CTX and rituximab (RTX. To identify any discriminatory therapeutic salivary biomarker patient's whole saliva was collected at the baseline, after the fourth infusion of rituximab, and on remission and analysed combining two-dimensional electrophoresis (2DE and MALDI-TOF/TOF mass spectrometry. Results Proteomic results obtained from the comparison of salivary samples indicated several qualitative and quantitative modifications in the salivary expression of putative albumin, immunoglobulin J chain, Ig kappa chain C region, alpha-1-antitrypsin, haptoglobin and Ig alpha-1 chain C region. Conclusion This study suggests that clinical and functional changes of the salivary glands driven by autoimmune and lymphoproliferative processes might be reflected in patients' whole saliva proteins, shedding new light on the potential usefulness of salivary proteomic analysis in the identification of prognostic and therapeutic biomarkers for patients with pSS and non Hodgkin's lymphomas.

    A highly selective, label-free sensor for the non-Hodgkin lymphoma gene, with an aM detection limit, utilizing electrochemical impedance spectroscopy (EIS) is presented. The sensor consists of a conducting electrospun fibre mat, surface-grafted with poly(acrylic acid) (PAA) brushes and a conducting polymer sensing element with covalently attached oligonucleotide probes. The sensor was fabricated from electrospun NBR rubber, embedded with poly(3,4-ethylenedioxythiophene) (PEDOT), followed by grafting poly(acrylic acid) brushes and then electrochemically polymerizing a conducting polymer monomer with ssDNA probe sequence pre-attached. The resulting non-Hodgkin lymphoma gene sensor showed a detection limit of 1aM (1 × 10 -18 mol/L), more than 400 folds lower compared to a thin-film analogue. The sensor presented extraordinary selectivity, with only 1%, 2.7% and 4.6% of the signal recorded for the fully non-complimentary, T-A and G-C base mismatch oligonucleotide sequences, respectively. We suggest that such greatly enhanced selectivity is due to the presence of negatively charged carboxylic acid moieties from PAA grafts that electrostatically repel the non-complementary and mismatch DNA sequences, overcoming the non-specific binding.

    Early diagnosis and staging of non-Hodgkin lymphoma (NHL) is essential for therapeutic strategy decision. Positron emission tomography/computed tomography (PET/CT) with fluorodeoxyglucose (FDG), a glucose analogue, labeled with fluor-18 ({sup 18F}-FDG) has been used to evaluate staging, therapy response and prognosis in NHL patients. However, in some cases, {sup 18F}-FDG has shown false- -positive uptake due to inflammatory reaction after chemo and/or radiation therapy. In this case report, we present a NHL patient evaluated with {sup 18F}-FDG and {sup 18F}-choline PET/CT scan imaging pre- and post-therapy. {sup 18F}-FDG and {sup 18F}-choline PET/CT were performed for the purpose of tumor staging and have shown intense uptake in infiltrative tissue as well as in the lymph node, but with some mismatching in the tumor. Post-treatment {sup 18F}-FDG and {sup 18F}-choline PET/ CT scans revealed no signs of radiotracer uptake, suggesting complete remission of the tumor. {sup 18F}-choline may be a complimentary tool for staging and assessment of therapeutic response in non-Hodgkin lymphoma, while non-{sup 18F}-FDG tracer can be used for targeted therapy and patient management.

    Intensive high-dose chemotherapy with autologous stem-cell support has become a common treatment strategy for non-Hodgkin's lymphomas. A cost-identification analysis was conducted comparing 10 patients autografted with PBSC to 10 others autografted with BM. The analysis included harvest and graft until graft day +100 and was carried out from the point of view of the hospital setting. Resources used, logistic and direct medical costs per patient were identified, and sensitivity analyses performed. The cost distribution was different. Stem cell harvest was more expensive for PBPC ($9030) and BM ($4745); on the other hand, hospitalization from graft to discharge from hospital cost savings with PBSC were about $10666. After discharge from hospital, costs were similar and cheaper in both groups. For the overall study the PBPC procedure was less expensive than ABMT, $35381 and $41759 respectively, with cost savings of $6378. The number of days spent in hospital and blood bank costs were the major cost factors. This study was based on a single pathology, non-Hodgkin's lymphoma, and the actual hospital records for each patient situation as opposed to a clinical trial, and our results were consistent with different previous studies carried out in different health care systems.

    Extranodal NK/T cell lymphoma, nasal type (ENKTL-NT) is an aggressive extranodal non-Hodgkin lymphoma most commonly occurring in East Asia and Latin America but with increasing incidence in the United States. Data on epidemiology, disease presentation, and outcome for European and North American ("Western") cases are very limited. We review published landmark clinical studies on ENKTL-NT in the West and report in detail recent data, including our institutional experience. We highlight key observations in its epidemiology, natural history, and trends in clinical management. In the USA, ENKTL-NT is more common among Asian Pacific Islanders (API) and Hispanics compared to non-Hispanic whites. Published studies indicate less heterogeneity in clinical presentation in Western ENKTL-NT compared to Asian patients. While there is variation in age at diagnosis, presence of antecedent lymphoproliferative disorders, and outcomes among racial/ethnic groups, the universal association of ENKTL-NT with EBV and the poor response of this neoplasm to anthracycline-based therapy is consistent across all geographic areas. Data on epidemiology, disease presentation, and clinical outcomes in mature T cell and NK cell (T/NK cell) neoplasms, including ENKTL-NT, in Europe and North America are very limited. As the classification and diagnostic characterization of the currently recognized T/NK cell lymphoma disease entities continue to evolve, gaps and inconsistencies in data reporting across different studies are being recognized. Despite these limitations, several studies from the USA suggest that the incidence of ENKTL-NT is higher in Asian Pacific Islanders (API) and non-white Hispanics and that outcomes may be worse in non-whites. However, the universal association of ENKTL-NT with Epstein-Barr virus (EBV) across all ethnic groups suggests a common pathogenesis. Given the overlap between the entities included in the category of T/NK cell neoplasms, there is a need to further define

    Usually, the middle-aged patients with non-Hodgkin's lymphoma and concomitant other adult diseases can not be tolerable for intensive chemotherapy. Then we introduced a new regimen composed of radiation for local and surrounding lymph node areas, and brief reduced-dose chemotherapy into treatment for such patients. Thirty-eight patients with Stage I E or Stage II E non-Hodgkin's lymphoma of the Waldeyer's ring were a core of this study. Histopathologically they were diagnosed as diffuse intermediate grade. In addition, they suffered from other adult diseases such as cardiovascular diseases, cereblovascular disorders, diabetes mellitus, chronic liver diseases, etc. They were treated by the combined modality composed of reduced-dose chemotherapy (70%-ACOP: 2 cycles or 70%-MACOP-B: 8 weeks) and regional lymph node irradiation (30 Gy) puls boost irradiation (10 Gy) to involved area (total 40 Gy). No relapses were observed in the radiation field, the 5-year disease-free survival rate and cause-specific survival rate for all patients were 85.7% and 91.4%, respectively. There were no differences of the 5-year disease-free survival rate between stage I E and II E , among the pathological subtypes, among the complications and etc. The regimen composed of regional lymph node irradiation (30 Gy) puls boost irradiation (10 Gy) to involved area (total 40 Gy) and reduced-dose chemotherapy (70%-dose ACOP, 70%-dose MACOP-B) is a safe and useful approach to treatment for diffuse intermediate grade of B cell lymphoma in middle-aged patients having other adult diseases.

A pilot study was undertaken to evaluate the potential for subcutaneous dosing with 2(nd) generation anti-CD20 antibody veltuzumab in patients with CD20(+) indolent non-Hodgkin's lymphoma. Patients with previously untreated or relapsed disease received 4 doses of 80, 160, or 320 mg veltuzumab injected subcutaneously every two weeks. Responses were assessed by computed tomography scans, with other evaluations including adverse events, safety laboratories, B-cell blood levels, serum veltuzumab levels, and human anti-veltuzumab antibody (HAHA) titers. Seventeen patients (14 follicular lymphoma; 13 stage III or IV disease; 5 treatment-naive) completed treatment with only occasional, mild-moderate, transient injection reactions and no other safety issues. Subcutaneous veltuzumab demonstrated a slow release pattern over several days, achieving a mean Cmax of 19, 25 and 63 μg/mL at 80, 160, and 320 mg doses for a total of 4 administrations, respectively. Depletion of circulating B cells occurred after the first injection. The objective response rate (partial responses plus complete responses plus complete responses unconfirmed) was 47% (8/17) with a complete response/complete response unconfirmed rate of 24% (4/17); 4 of 8 objective responses continued for 60 weeks or more. All serum samples evaluated for human anti-veltuzumab antibody were negative. Subcutaneous injections of low-dose veltuzumab are convenient, well tolerated, and capable of achieving sustained serum levels, B-cell depletion, and durable objective responses in indolent non-Hodgkin's lymphoma.

Clinicians relay on PI as a surrogate marker of biologic activity; however, no established guidelines have been published whether PI at the primary site of the tumor gives the same answer as evaluation of tumor in staging marrow. In our study, dual immunohistochemical staining for MIB1 and CD20 was performed on tissue from primary site and bone marrow involved by B-cell non-Hodgkin lymphoma to compare PI for each individual patient. For all patients, MIB1 expression was higher at primary tumor site as compared to staging marrow. Additional analysis was performed to investigate the degree of difference depending on lymphoma morphology. Patients with large cell lymphoma at the primary site and large cell morphology in the marrow (LCL-L, those with large cell morphology at the primary site and small cell morphology in the marrow (LCL-S, and those with small cell morphology at the primary site and small cells in the marrow (SCL-S were compared. As expected, LCL cases had a higher mean PI at the primary site when compared to SCL cases (28.5% vs 2.8%, P=0.0001. In addition, the most significant difference between medullary and extramedullary PI was observed in cases with discordant morphology (LCL-S (21% vs 1.1%, P=0.009. Our results indicate that PI of lymphoma within the bone marrow should not be used as a surrogate prognostic indicator of lymphoma biology in its primary site.

    Despite complex treatment schedules for cancer, the occurrence of resistances and relapses is a major concern in oncology. Hence, novel treatment options are needed. In this thesis, different approaches using radioimmunotherapy and the opioid D,L-methadone alone or in combination with doxorubicin were analyzed regarding their cytotoxic potential and the triggered signalling pathways in sensitive and resistant leukaemia and non-Hodgkin lymphoma (NHL). The radioimmunoconjugates [Bi-213]anti-CD33 and [Bi-213]anti-CD20 for treatment of acute myeloid leukaemia (AML) or NHL, respectively, were applied exemplary for the use of targeted alpha-therapies (TAT). Depending on the analyzed cell lines, the used activity concentrations and specific activities (MBq/μg antibody) apoptosis was induced abrogating radio- and chemo-cross-resistances specifically. The cell death was caspase-dependent activating the mitochondrial pathway and was executed by downregulation of the anti-apoptotic proteins XIAP and Bcl-xL. D,L-Methadone induces apoptosis in vitro and in vivo in opioid-receptor (OR) expressing cells depending on the OR density and the used concentrations. Resistances could be overcome and proliferation was inhibited. In combination with doxorubicin, a synergistic effect regarding cytotoxicity in ex vivo patient cells and cell lines was observed. This effect depends on the increase of doxorubicin uptake co-administering D,L-methadone whereas doxorubicin enhances OR expression. The activation of OR leads to the downregulation of cAMP playing a pivotal role in apoptosis induction. In vivo, the therapeutic potential of D,L-methadone alone or in combination with doxorubicin could be proven as mice transplanted with human T-ALL-cells could be identified as tumour free. In summary, these studies show that TAT using [Bi-213]anti-CD33 and [Bi-213]anti-CD20 as well as the opioid D,L-methadone harbour the potential to optimize conventional treatment modalities for leukaemia and NHL.

    Background: Infections are life-threatening complications in patients undergoing high-dose chemotherapy with stem cell support (HDT). Knowledge of the infectious pathogens is essential to make a safe outpatient setting. Methods: We conducted a retrospective study of 208 patients treated with HDT...... related mortality was similar between the groups. Conclusion: The frequency of isolated pathogens, positive blood cultures, and the diversity of pathogens were higher in MM patients as compared to NHL patients. However, this did not translate into higher transplantation-related mortality, probably because....... The population included non-Hodgkin lymphoma (NHL) and multiple myeloma (MM) patients. No patients received prophylactic antibacterial treatment. Results: Pathogens were isolated from 44% of all patients. MM patients more frequently had multiple pathogens in blood cultures (38% versus 25%). Transplantation...

    Between 1971 and 1976, 64 patients less than 18 years of age with non-Hodgkin's lymphoma were treated at Boston's Children's Hospital Medical Center-Joint Center for Radiation Therapy. A multimodality approach was used, consisting of radiation therapy (3500 to 4500 rad), surgery, and chemotherapy. Since 1973, all patients have received a regimen initially comprising Adriamycin, Prednisone, 6-Mercaptopurine, Vincristine, and L-Asparaginase. Methotrexate was substituted for Adriamycin following a cumulative total dose of 450 mg/m/sup 2/. The 5-year actuarial survival for all patients was 61%, while relapse-free survival was 54%. The actuarial and relapse-free survival for patients presenting with localized disease was 75% and 72%, respectively. Median follow-up was 40 months and all relapses occurred within 24 months of initial therapy. A multidisciplinary approach, such as the current regimen, offers a good prognosis for this disease.

    Full Text Available Abstract Background A positive family history of chronic diseases including cancer can be used as an index of genetic and shared environmental influences. The tumours studied have several putative risk factors in common including occupational exposure to certain pesticides and a positive family history of cancer. Methods We conducted population-based studies of Hodgkin lymphoma (HL, Multiple Myeloma (MM, non-Hodgkin's Lymphoma (NHL, and Soft Tissue Sarcoma (STS among male incident case and control subjects in six Canadian provinces. The postal questionnaire was used to collect personal demographic data, a medical history, a lifetime occupational history, smoking pattern, and the information on family history of cancer. The family history of cancer was restricted to first degree relatives and included relationship to the index subjects and the types of tumours diagnosed among relatives. The information was collected on 1528 cases (HL (n = 316, MM (n = 342, NHL (n = 513, STS (n = 357 and 1506 age ± 2 years and province of residence matched control subjects.

    As CD20 has become an established target for treating B-cell malignancies, there is interest in developing anti-CD20 antibodies with different functional activity from rituximab that might translate into improved efficacy. Obinutuzumab (GA101) is a glycoengineered, humanized type II anti-CD20 monoclonal antibody that has demonstrated superior activity to type I antibodies in preclinical studies and is currently being investigated in phase III trials. In this phase I dose-escalating study in Japanese patients with relapsed/refractory B-cell non-Hodgkin lymphoma, the primary endpoint was to characterize the safety of GA101; secondary endpoints were efficacy, pharmacokinetics and pharmacodynamics. Patients received up to nine doses of GA101 with up to 52 weeks' follow up. Most adverse events were grade 1 or 2 infusion-related reactions, and 10 grade 3/4 adverse events occurred. No dose-limiting toxicities were observed and the maximum tolerated dose was not identified. Out of 12 patients, 7 responded (end-of-treatment response rate 58%), with 2 complete responses and 5 partial responses. Responses were observed from low to high doses, and no dose-efficacy relationship was observed. B-cell depletion occurred in all patients after the first infusion and was maintained for the duration of treatment. Serum levels of GA101 increased in a dose-dependent fashion, although there was inter-patient variability. This phase I study demonstrated that GA101 has an acceptable safety profile and offers encouraging activity to Japanese patients with relapsed/refractory B-cell non-Hodgkin lymphoma. © 2012 Japanese Cancer Association.

  2. Prognosis and treatment after relapse of acute lymphoblastic leukemia and non-Hodgkin's lymphoma: 1985. A report from the Childrens Cancer Study Group

    1986-01-01

    Acute lymphoblastic leukemia and non-Hodgkin's lymphoma constitute 42% to 45% of the cancers in infants, children, and adolescents: In 1985, an estimated 2025 children were newly diagnosed with these two cancers and 900 (43%) of the pediatric cancer deaths in the United States have been projected to be due to these diseases. The single most important obstacle to preventing these deaths is relapse, and prevention of relapse or salvage of the patient who has had a relapse continues to be a major therapeutic challenge. The most important initial step in the treatment of the child whose disease has relapsed is to determine, to the extent possible, the prognosis. In a child with non-Hodgkin's lymphoma, a relapse confers an extremely poor prognosis, regardless of site of relapse, tumor histology, or other original prognostic factors, prior therapy, or time to relapse. In the child with acute lymphoblastic leukemia in relapse, the prognosis depends on multiple factors. The primary therapy is chemotherapy or chemoradiotherapy with marrow grafting. Other options exist, including no therapy, or investigational therapy. The therapy selected should be predicated on the prognosis. In the child with an isolated central nervous system (CNS) relapse off therapy, minimum therapy should be administered, particularly if the relapse occurred without prior cranial irradiation. In the child whose relapse is more than 6 months off therapy, conventional therapy should be considered. Also, a patient with an isolated CNS relapse on therapy after prior cranial irradiation should be given moderate therapy. Bone marrow transplantation or high-dose chemoradiotherapy with autologous marrow rescue should be reserved in children with a second or subsequent extramedullary relapse, and possibly for those with a first isolated overt testicular relapse on therapy

    Shorter survival has been associated with low socioeconomic status (SES) among elderly non-Hodgkin's lymphoma (NHL) patients; however it remains unknown whether the same relationship holds for younger patients. We explored the California Cancer Registry (CCR), to investigate this relationship in adolescent and young adult (AYA) NHL patients diagnosed from 1996 to 2005. A case-only survival analysis was conducted to examine demographic and clinical variables hypothesized to be related to survival. Included in the final analysis were 3,489 incident NHL cases. In the multivariate analyses, all-cause mortality (ACM) was higher in individuals who had later stage at diagnosis (P<.05) or did not receive first-course chemotherapy (P<.05 ). There was also a significant gradient decrease in survival, with higher ACM at each decreasing quintile of SES (P<.001). Overall results were similar for lymphoma-specific mortality. In the race/ethnicity stratified analyses, only non-Hispanic Whites (NHWs) had a significant SES-ACM trend ( P<.001). Reduced overall and lymphoma-specific survival was associated with lower SES in AYAs with NHL, although a significant trend was only observed for NHWs

    Massively parallel sequencing analyses have revealed a common mutation within the MYD88 gene (MYD88 L265P ) occurring at high frequencies in many non-Hodgkin lymphomas (NHLs) including the rare lymphoplasmacytic lymphoma, Waldenström's macroglobulinemia (WM). Using whole-exome sequencing, Sanger sequencing and allele-specific PCR, we validate the initial studies and detect the MYD88 L265P mutation in the tumor genome of 97% of WM patients analyzed (n=39). Due to the high frequency of MYD88 mutation in WM and other NHL, and its known effects on malignant B-cell survival, therapeutic targeting of MYD88 signaling pathways may be clinically useful. However, we are lacking a thorough characterization of the role of intermediary signaling proteins on the biology of MYD88 L265P -expressing B cells. We report here that MYD88 L265P signaling is constitutively active in both WM and diffuse large B-cell lymphoma cells leading to heightened MYD88 L265P , IRAK and TRAF6 oligomerization and NF-κB activation. Furthermore, we have identified the signaling protein, TAK1, to be an essential mediator of MYD88 L265P -driven signaling, cellular proliferation and cytokine secretion in malignant B cells. Our studies highlight the biological significance of MYD88 L265P in NHL and reveal TAK1 inhibition to be a potential therapeutic strategy for the treatment of WM and other diseases characterized by MYD88 L265P

    Full Text Available Non-Hodgkin lymphoma (NHL is a hematological tumor caused by abnormal lymphoid proliferation. NHL can arise in any part of the body, including central nervous system (CNS. However, pituitary involvement is a quite rare presentation. The diffuse large B-cell lymphoma (DLBCL is the most common subtype when pituitary is infiltrated. Here, we report a case of pituitary infiltration of NHL DLBCL type in a woman with hypopituitarism and an infundibulum-hypophysitis-like image on magnetic resonance imaging (MRI. A female aged 64 years, complained of dyspepsia, fatigue, weight loss and urine volume increment with thirst. Endoscopy and gastric biopsy confirmed diffuse large B-cell lymphoma. Treatment with chemotherapy using R-CHOP was initiated. During her hospitalization, hypotension and polyuria were confirmed. Hormonal evaluation was compatible with central diabetes insipidus and hypopituitarism. Simple T1 sequence of MRI showed thickening of the infundibular stalk with homogeneous enhancement. After lumbar puncture analysis, CNS infiltration was confirmed showing positive atypical lymphocytes. Pituitary and infundibular stalk size normalized after R-CHOP chemotherapy treatment. In conclusion, pituitary infiltration of NHL with infundibular-hypophysitis-like image on MRI is a rare finding. Clinical picture included hypopituitarism and central diabetes insipidus. Diagnosis should be suspected after biochemical analysis and MRI results. Treatment consists of chemotherapy against NHL and hormonal replacement for pituitary dysfunction.

    Full Text Available 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.

    For decades lymphoma patients are, whenever possible, treated in clinical trials. This thesis is based on 30 years experience of large clinical trials by the EORTC (European Organization for Research and Treatment of Cancer) Lymphoma Group in aggressive non-Hodgkin’s lymphoma (NHL).

    The aim of this study was to assess the clinical benefit of combined [ 18 F]FDG PET/CT in patients with malignant lymphoma as compared to separately performed PET and CT. Overall, 100 patients with Hodgkin's disease (HD) or non-Hodgkin's lymphoma (NHL) were included in this study. Co-registered PET/CT with [ 18 F]FDG and contrast medium was performed in 50 consecutive patients with NHL (n=38) or HD (n=12) for initial staging (IS) (n=12) or re-treatment staging (RS) (n=38). Another 50 patients with NHL (n=32) or HD (n=18) underwent separate PET and CT investigations within a time frame of 10 days for IS (n=22) or RS (n=28). Lymphoma involvement was separately evaluated for seven different regions in each patient. Each patient had clinical follow-up evaluation for >6 months. PET and CT data were analysed separately as well as side-by-side or in fused mode. In the PET/CT group, region-based evaluation for lymphoma involvement suggested a sensitivity/specificity of 85%/91% for CT, 98%/99% for PET and 98%/99% for PET/CT. In the PET and CT group, region-based evaluation showed a sensitivity/specificity of 87%/80% for CT, 98%/99% for PET and 98%/100% for PET and CT read side by side. PET was superior to CT alone and was improved further by side-by-side reading of both examinations. However, no significant difference was observed between PET/CT and separate PET and CT imaging in patients with lymphoma. (orig.)

    The purpose of this study was to investigate the ability of computed tomography texture analysis (CTTA) to provide additional prognostic information in patients with Hodgkin's lymphoma (HL) and high-grade non-Hodgkin's lymphoma (NHL). This retrospective, pilot-study approved by the IRB comprised 45 lymphoma patients undergoing routine 18F-FDG-PET-CT. Progression-free survival (PFS) was determined from clinical follow-up (mean-duration: 40 months; range: 10-62 months). Non-contrast-enhanced low-dose CT images were submitted to CTTA comprising image filtration to highlight features of different sizes followed by histogram-analysis using kurtosis. Prognostic value of CTTA was compared to PET FDG-uptake value, tumour-stage, tumour-bulk, lymphoma-type, treatment-regime, and interim FDG-PET (iPET) status using Kaplan-Meier analysis. Cox regression analysis determined the independence of significantly prognostic imaging and clinical features. A total of 27 patients had aggressive NHL and 18 had HL. Mean PFS was 48.5 months. There was no significant difference in pre-treatment CTTA between the lymphoma sub-types. Kaplan-Meier analysis found pre-treatment CTTA (medium feature scale, p=0.010) and iPET status (p<0.001) to be significant predictors of PFS. Cox analysis revealed that an interaction between pre-treatment CTTA and iPET status was the only independent predictor of PFS (HR: 25.5, 95% CI: 5.4-120, p<0.001). Specifically, pre-treatment CTTA risk stratified patients with negative iPET. CTTA can potentially provide prognostic information complementary to iPET for patients with HL and aggressive NHL.

    Proteasome inhibitors and mammalian target of rapamycin inhibitors each have activity in various B-cell malignancies and affect distinct cellular pathways. Their combination has demonstrated synergy in vitro and in mouse models. The authors conducted a single-arm, phase 2 trial of combined temsirolimus and bortezomib in patients with relapsed and refractory B-cell non-Hodgkin lymphoma (NHL) using a dosing scheme that was previously tested in multiple myeloma. The patients received bortezomib and temsirolimus weekly on days 1, 8, 15, and 22 of a 35-day cycle. Of 39 patients who received treatment, 3 achieved a complete response (7.7%; 95% confidence interval [CI], 1.6%-21%), and 9 had a partial response (PR) (23%; 95% CI, 11%-39%). Thus, the overall response rate (12 of 39 patients) was 31% (95% CI, 17%-48%), and the median progression-free survival was 4.7 months (95% CI, 2.1-7.8 months; 2 months for patients with diffuse large B-cell lymphoma [n = 18], 7.5 months for those with mantle cell lymphoma [n = 7], and 16.5 months for those with follicular lymphoma [n = 9]). Two extensively treated patients with diffuse large B-cell lymphoma achieved a complete response. There were no unexpected toxicities from the combination. The current results demonstrate that the combination of a mammalian target of rapamycin inhibitor and a proteasome inhibitor is safe and has activity in patients with heavily pretreated B-cell NHL. Further studies with this combination are warranted in specific subtypes of NHL. © 2015 American Cancer Society.

    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.

    Objective: To report an aggressive case of extranodal natural killer/T-cell lymphoma (NKTCL) of the ethmoid sinus presenting as orbital cellulitis Method: Case report Results: A 56-year-old male presented with right eye redness, reduced vision, and periorbital swelling for 5 weeks duration associated with a two-month history of blocked nose. The visual acuity of the right eye was 6/18. The eye was proptosed with periorbital oedema and conjunctival chemosis. The pupil was mid-dilated but there was no relative afferent pupillary defect. The fundus was normal. The extraocular movements were restricted in all directions of gaze. Nasal endoscopy revealed pansinusitis that corresponded with CT scan orbit and paranasal sinuses findings. Despite treatment, he showed no clinical improvement. Ethmoidal sinus biopsies performed revealed extranodal NKTCL. Further imaging showed involvement of the right orbital contents and its adnexa with intracranial extension into the right cavernous sinus and meninges over right temporal fossa. The patient underwent chemotherapy. However he succumbed to his illness two months after the diagnosis. Conclusion: Extranodal NKTCL is a great mimicker. This case demonstrated how an acute initial presentation of extranodal NKTCL can present as orbital cellulitis with pansinusitis. PMID:28194321

    The gastrointestinal tract is the most common site for extranodal involvement by non-Hodgkin's lymphoma. However, primary appendiceal lymphomas presenting as perforated acute appendicitis are very rare: they occur in only 0.015% of all gastrointestinal lymphoma cases. The management of this condition is still controversial, and a multimodality approach (e.g., surgery, radiation therapy, and chemotherapy) is the optimal treatment. In these cases, appendiceal non-Hodgkin's lymphomas typically manifest with acute symptoms in patients with no prior lymphoma history. Additionally, we treated our patient with a right hemicolectomy and postoperative multiagent chemotherapy.

    Trimethylcolchicinic acid methyl ether d-tartrate (TMCA; NSC-36351) was administered daily by mouth to 71 patients with malignant lymphomas. Partical (greater than 50%) responses were observed in eleven of 37 patients with Hodgkin's disesse, two of 22 patients with lymphocytic lymphoma, and one of two patients with mixed cell lymphoma. One complete and three partial responses were noted in nine patients with histiocytic lymphoma. Responses lasted from one to 91+ months (median: four months) and occurred in patients whose disease was resistant to alkylating agents, vinblastine, vincristine, procarbazine, prednisone or BCNU. Toxic effects included leukopenia, thrombocytopenia, nausea, diarrhea, stomatitis, alopecia and dermatitis.

    As a population, non-Hodgkin's lymphoma (NHL) cell lines positive for the t(14;18) translocation and/or possessing elevated BCL2 copy number (CN; BCL2 High ) are exquisitely sensitive to navitoclax or the B-cell lymphoma protein-2 (BCL-2)-selective inhibitor venetoclax. Despite this, some BCL2 High cell lines remain resistant to either agent. Here we show that the MCL-1-specific inhibitor A-1210477 sensitizes these cell lines to navitoclax. Chemical segregation of this synergy with the BCL-2-selective inhibitor venetoclax or BCL-X L -selective inhibitor A-1155463 indicated that MCL-1 and BCL-2 are the two key anti-apoptotic targets for sensitization. Similarly, the CDK inhibitor flavopiridol downregulated MCL-1 expression and synergized with venetoclax in BCL2 High NHL cell lines to a similar extent as A-1210477. A-1210477 also synergized with navitoclax in the majority of BCL2 Low NHL cell lines. However, chemical segregation with venetoclax or A-1155463 revealed that synergy was driven by BCL-X L inhibition in this population. Collectively these data emphasize that BCL2 status is predictive of venetoclax potency in NHL not only as a single agent, but also in the adjuvant setting with anti-tumorigenic agents that inhibit MCL-1 function. These studies also potentially identify a patient population (BCL2 Low ) that could benefit from BCL-X L (navitoclax)-driven combination therapy

    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.

    The efficacy of the prototypical phosphatidylinositol-3-kinase (PI3K) inhibitor idelalisib for the treatment of chronic lymphocytic leukemia (CLL) and indolent non-Hodgkin lymphoma (iNHL) has led to development of multiple compounds targeting this pathway. Areas Covered: We review the hypothesized therapeutic mechanisms of PI3K inhibitors, including abrogation of B cell receptor signaling, blockade of microenvironmental pro-survival signals, and enhancement of anti-tumor immunity. We examine toxicities of idelalisib, including bacterial infections (possibly secondary to drug-induced neutropenia), opportunistic infections (possibly attributable to on-target inhibition of T cell function), and organ toxicities such as transaminitis and enterocolitis (possibly autoimmune, secondary to on-target inhibition of p110δ in regulatory T cells). We evaluate PI3K inhibitors that have entered trials for the treatment of lymphoma, focusing on agents with selectivity for PI3Kα and PI3Kδ. Expert Opinion: PI3K inhibitors, particularly those that target p110δ, have robust efficacy in the treatment of CLL and iNHL. However, idelalisib has infectious and autoimmune toxicities that limit its use. Outside of trials, idelalisib should be restricted to CLL patients with progression on ibrutinib or iNHL patients with progression on two prior therapies. Whether newer PI3K inhibitors will demonstrate differentiated toxicity profiles in comparable patient populations while retaining efficacy remains to be seen.

    Abstract Rationale: We report the rare case of a 74-year-old man with anti-Ma2–associated paraneoplastic neurologic syndrome (PNS), and review and analyze the clinical manifestations, diagnosis, and treatment of the disease. Patient concerns: The patient presented with a 5-month history of muscle weakness, progressive body aches, and weakness and numbness in both lower extremities. Before his hospitalization, he had experienced cognitive function decline; ptosis, inward gaze, and vertical gaze palsy in the right eye; and occasional visual hallucinations. Brain and spinal cord magnetic resonance imaging (MRI) yielded normal results. Anti-Ma2 antibodies were detected in both serum and cerebrospinal fluid. A 4-hour electroencephalogram showed irregular sharp slow waves and δ waves in the temporal region. Electromyography showed peripheral nerve demyelination. Positron-emission tomography/computed tomography (PET-CT) examination revealed hypermetabolism in the lymph nodes of the whole body. Biopsy of the lymph nodes showed non-Hodgkin lymphoma. Diagnosis: A clinical diagnosis of lymphoma and PNS was made. Interventions: The patient was treated with intravenous dexamethasone (15 mg/day) for 3 days. Lessons: We have presented a rare case of a PNS involving both the central and peripheral nervous systems. The clinical features of this case indicated anti-Ma2–associated encephalitis and chronic inflammatory demyelinating polyneuropathy. PET-CT played a critical role in enabling early diagnosis and prompt treatment in this case. PMID:28984777

    Cutaneous malignancy is associated with worse outcomes in patients with chronic lymphocytic leukemia (CLL). We sought to identify the incidence and recurrence rate of nonmelanoma skin cancer (NMSC) in patients with non-Hodgkin lymphoma (NHL). NMSC incidence was calculated and Cox proportional hazards models were used to evaluate associations with risk of recurrence for patients with NHL between 1976 and 2005 who were in the Rochester Epidemiology Project research infrastructure. We identified 282 patients with CLL or small lymphocytic lymphoma and 435 with non-CLL NHL. The incidence of basal cell carcinoma and squamous cell carcinoma was 1829.3 (95% confidence interval [CI] 1306.7-2491.1) and 2224.9 (95% CI 1645.9-2941.6), respectively, in patients with CLL. The cumulative recurrence rate at 8 years after treatment with Mohs micrographic surgery was 8.3% (95% CI 0.0%-22.7%) for basal cell carcinoma and 13.4% (95% CI 0.0%-25.5%) for squamous cell carcinoma in patients with CLL. This was a retrospective cohort study. After Mohs micrographic surgery and standard excision of NMSC, patients with NHL had a skin cancer recurrence rate that was higher than expected. Careful treatment and monitoring of patients with NHL and NMSC are warranted. Copyright © 2014 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

    Full Text Available Hepatitis B virus (HBV is hepatotropic and lymphotropic. HBV-infected individuals have an increased risk of developing malignant lymphoma, and the HBV infection rate in lymphoma patients is significantly higher than that in the general population. However, the exact mechanism and correlation between HBV infection and lymphoma onset and progression currently remain unclear. We retrospectively analyzed clinical data from non-Hodgkin's lymphoma (NHL patients with different HBV infection statuses. The results showed that the HBV infection rate was significantly higher in patients with B-cell type and late stage of NHL. The chemotherapy efficacy for NHL patients with chronic active HBV infection was significantly lower than that for the patients with chronic inactive HBV infection, the patients with HBV carriers and the patients without HBV infection. In addition, the NHL chemotherapy activated HBV replication and caused significant liver dysfunction, which could further reduce the chemotherapy efficacy. Through Kaplan-Meier survival curve and log-rank analysis, we found that the HBV infection status in NHL patients was significantly correlated with the patients' progression-free survival (PFS and overall survival (OS. Compared with the patients without HBV infection (PFS: 95% CI 47.915 to 55.640; OS: 95% CI 81.324 to 86.858, the PFS and OS of the patients with chronic active HBV infection were significantly shorter (PFS: 95% CI 9.424 to 42.589, P < 0.001; OS: 95% CI 42.840 to 82.259, P = 0.006. The study demonstrated that the sustained HBV replication in patients with chronic active HBV infection could be a key factor that influences the prognosis of NHL patients after chemotherapy, and thus may provide information for designing rational clinical treatments for NHL patients with different HBV infection statuses and improve the treatment efficacy and prognosis.

    Full Text Available Abstract Background The risk of developing lymphoma is greatly increased in HIV infection. Musculoskeletal manifestations of the human immunodeficiency virus (HIV are common and are sometimes the initial presentation of the disease. Muscle, bone, and joints are involved by septic arthritis, myopathies and neoplasms. HIV-related neoplastic processes that affect the musculoskeletal system include Kaposi's sarcoma and non-Hodgkin's lymphoma, the latter being mainly localized at lower extremities, spine and skull. Case presentation The Authors report a case of a 34 year-old lady. In December 2003 the patient noted a painless mass on her right shoulder whose size increased progressively. In March 2004 she was diagnosed HIV positive and contemporary got pregnant. The patient decided to continue her pregnancy and to not undergo any diagnostic procedure and treatment. At the end of August she underwent a surgical ablation of the lesion that revealed a lesion of 7 cm × 7 cm × 3,3 cm. The histology showed B-cells expressing CD20, PAX-5, CD10, BCL-6 and MUM-1 with 70% Ki67 positive nuclei. The lesion was also negative for EBV infection and showed a monoclonal rearrangement of IgH chain and a polyclonal pattern for TCR gamma and beta. A final diagnosis of diffuse large B-cell lymphoma was made. The patient underwent postoperative chemotherapy. At four-years follow up the patient is symptom free and no local nor systemic recurrence of pathology has been noted on MRI control. HIV infection is still under control. Conclusion In this report, we present a case of diffuse large B-cell lymphoma localized in the soft tissue of the shoulder in a HIV infected patient. Authors want to underline this case for the rare position, the big size and the association with HIV infection.

    Lymphoma is a malignant neoplasm of component cells of the lymphoid system which is very rare in the jaws. Here we report a case of primary diffuse large B-cell lymphoma located in the periapical region of a mandibular molar which was misdiagnosed as chronic periapical periodontitis. The present case was diagnosed at an early stage and effectively managed by chemotherapy. Although lymphoma of the mandible is rare, it must be considered in the differential diagnosis of radiolucent lesions in this region. Lack of knowledge of this rare presentation may lead to delays in diagnosis and poor prognosis. © 2013 Australian Dental Association.

    Full Text Available 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.

Hoffmann La-Roche Ltd, Basel, Switzerland; 4Clinical Outcomes Solutions, Tucson, AZ, USA Background: A subcutaneous (SC formulation of rituximab (MabThera®/Rituxan® has been developed that could reduce administration time and improve patient satisfaction with treatment. The Rituximab Administration Satisfaction Questionnaire (RASQ was created to assess patients’ perceptions and satisfaction with rituximab SC (RASQ-SC or rituximab intravenous (RASQ-IV. We assessed the content validity and psychometric properties of RASQ in patients with non-Hodgkin lymphoma.Methods: Face and content validity of RASQ-SC and RASQ-IV were qualitatively assessed using 60-minute combined concept elicitation and cognitive debriefing interviews. Psychometric validation of RASQ (item performance and reliability was assessed quantitatively against the established Cancer Therapy Satisfaction Questionnaire (CTSQ, using questionnaire data from the PrefMab (NCT01724021 and MabCute (NCT01461928 clinical studies.Results: RASQ-IV demonstrated excellent coverage of concepts relevant to patients’ (n=10 own treatment experiences and no new concepts were identified. Patients’ expectations of rituximab SC were conceptually consistent with items included in the RASQ-SC, suggesting that the tool is also conceptually adequate. In 1,051 patients from PrefMab and MabCute, correlations with domains such as “RASQ: Physical Impacts” and “CTSQ: Feelings About Side Effects”, “RASQ: Physical Impacts” and “CTSQ: Satisfaction With Therapy”, and “RASQ: Satisfaction” and “CTSQ: Satisfaction With Therapy”, achieved moderate-to-high correlations (>0.4 for convergent domains and <0.3 for divergent domains.Conclusion: This study supports the qualitative face and

    BACKGROUND: Numerous genomic abnormalities in B-cell non-Hodgkin lymphomas (NHLs) have been revealed by novel high-throughput technologies, including recurrent mutations in EZH2 (enhancer of zeste homolog 2) and CD79B (B cell antigen receptor complex-associated protein beta chain) genes. This study sought to determine the evolution of the mutational status of EZH2 and CD79B over time in different samples from the same patient in a cohort of B-cell NHLs, through use of a customized multiplex mutation assay. METHODS: DNA that was extracted from cytological material stored on FTA cards as well as from additional specimens, including archived frozen and formalin-fixed histological specimens, archived stained smears, and cytospin preparations, were submitted to a multiplex mutation assay specifically designed for the detection of point mutations involving EZH2 and CD79B, using MassARRAY spectrometry followed by Sanger sequencing. RESULTS: All 121 samples from 80 B-cell NHL cases were successfully analyzed. Mutations in EZH2 (Y646) and CD79B (Y196) were detected in 13.2% and 8% of the samples, respectively, almost exclusively in follicular lymphomas and diffuse large B-cell lymphomas. In one-third of the positive cases, a wild type was detected in a different sample from the same patient during follow-up. CONCLUSIONS: Testing multiple minimal tissue samples using a high-throughput multiplex platform exponentially increases tissue availability for molecular analysis and might facilitate future studies of tumor progression and the related molecular events. Mutational status of EZH2 and CD79B may vary in B-cell NHL samples over time and support the concept that individualized therapy should be based on molecular findings at the time of treatment, rather than on results obtained from previous specimens.

    Survival in patients with acquired immunodeficiency syndrome (AIDS) related non-Hodgkin's Lymphoma has improved with the use of High Active Antiretroviral Therapy (HAART) and less toxic chemotherapy. Clinical characteristics and outcome among patients treated for AIDS related non-Hodgkin's Lymphoma are described. Nine patients were studied retrospectively. Overall survival (OS) and Free Disease Survival (FDS) using a Kaplan-Meier model were analyzed. Patients received (DA-EPOCH) etoposide, prednisone, vincristine, doxorubicin and cyclophosphamide. The overall Survival was 18 months and 13 month Free Disease Survival with a median follow-up of 16 months showing full response in 8/9 patients was observed. A very satisfactory treatment response in this group of patients expressed as an increased Overall Survival was noted.

  13. Overexpression of microRNAs from the miR-17-92 paralog clusters in AIDS-related non-Hodgkin's lymphomas.

    Full Text Available Individuals infected by HIV are at an increased risk for developing non-Hodgkin's lymphomas (AIDS-NHL. In the highly active antiretroviral therapy (HAART era, there has been a significant decline in the incidence of AIDS-associated primary central nervous system lymphoma (PCNSL. However, only a modest decrease in incidence has been reported for other AIDS-NHL subtypes. Thus, AIDS-NHLs remain a significant cause of morbidity and mortality in HIV infected individuals. Recently, much attention has been directed toward the role of miRNAs in cancer, including NHL. Several miRNAs, including those encoded by the miR-17-92 polycistron, have been shown to play significant roles in B cell tumorigenesis. However, the role of miRNAs in NHL in the setting of HIV infection has not been defined.We used quantitative realtime PCR to assess the expression of miRNAs from three different paralog clusters, miR-17-92, miR-106a-363, and miR-106b-25 in 24 cases of AIDS-NHLs representing four tumor types, Burkitt's lymphoma (BL, n = 6, diffuse large B-cell lymphoma (DLBCL, n = 8, primary central nervous system lymphoma (PCNSL, n = 5, and primary effusion lymphoma (PEL, n = 5. We also used microarray analysis to identify a differentiation specific miRNA signature of naïve, germinal center, and memory B cell subsets from tonsils (n = 4. miRNAs from the miR-17-92 paralog clusters were upregulated by B cells, specifically during the GC differentiation stage. We also found overexpression of these miRNA clusters in all four AIDS-NHL subtypes. Finally, we also show that select miRNAs from these clusters (miR-17, miR-106a, and miR-106b inhibited p21 in AIDS-BL and DLBCL cases, thus providing a mechanistic role for these miRNAs in AIDS-NHL pathogenesis.Dysregulation of miR-17-92 paralog clusters is a common feature of AIDS-associated NHLs.

    Despite substantial recent advances, there is still an unmet need for better therapies in B-cell non Hodgkin lymphomas (B-NHL), especially in relapsed or refractory disease. Many novel targeted drugs have been developed based on a better molecular understanding of B-NHL. Areas covered: This article focuses on chronic lymphocytic leukemia (CLL) as a representative for indolent lymphomas and paradigmatic for the tremendous progress in treating B-NHL on the one hand and diffuse large B-cell lymphoma (DLBCL) as a representative for aggressive lymphomas and paradigmatic for many unsolved problems in lymphoma treatment or the other hand. We highlight salient points in current therapies targeting genetic, epigenetic, immunological and microenvironmental alterations. Possible reasons for drug failure in clinical trials like tumor heterogeneity, clonal evolution and drug resistance mechanisms are discussed. Based thereon, some perspectives for further drug discovery are given. Expert opinion: In view of the pathogenetic complexity of lymphomas, therapies targeting exclusively a single alteration may fail because resistance mechanisms are present either initially or evolve during treatment. Therefore, future therapies in B-NHL may have to target the greatest possible number of genetic, immunological or epigenetic alterations still allowing tolerability and to monitor these alterations during therapy.

    Growth arrest lines appear as dense sclerotic lines parallel to the growth plate of long bones on radiography. We describe the case of a 9-year-old female with growth arrest lines initially masquerading as lymphoma involvement on {sup 99m}Tc-MDP bone scintigraphy who had been treated with chemotherapy for non-Hodgkin's lymphoma about 3 years previously. Subsequent regional bone SPECT/CT clearly diagnosed the growth arrest lines, and retrograde review of previous bone scintigraphy demonstrated line migration in this patient. Growth arrest lines should be considered a possible diagnosis on bone scintigraphy, especially in the surveillance of children who have experienced severe childhood infections, malnutrition, immobilization, or treatment with immunosuppressive or chemotherapeutic drugs that may inhibit bone growth.

    Full Text Available Background. The homeostatic chemokine, CXCL13 (BLC, BCA-1, helps direct the recirculation of mature, resting B cells, which express its receptor, CXCR5. CXCL13/CXCR5 are expressed, and may play a role, in some non-AIDS-associated B cell tumors. Objective. To determine if CXCL13/CXCR5 are associated with AIDS-related non-Hodgkin's lymphoma (AIDS-NHL. Methods. Serum CXCL13 levels were measured by ELISA in 46 subjects who developed AIDS-NHL in the Multicenter AIDS Cohort Study and in controls. The expression or function of CXCL13 and CXCR5 was examined on primary AIDS-NHL specimens or AIDS-NHL cell lines. Results. Serum CXCL13 levels were significantly elevated in the AIDS-NHL group compared to controls. All primary AIDS-NHL specimens showed CXCR5 expression and most also showed CXCL13 expression. AIDS-NHL cell lines expressed CXCR5 and showed chemotaxis towards CXCL13. Conclusions. CXCL13/CXCR5 are expressed in AIDS-NHL and could potentially be involved in its biology. CXCL13 may have potential as a biomarker for AIDS-NHL.

    The hepatitis C virus (HCV) core protein is able to accumulate genetic p53 mutations and may be considered co-oncogenic. This study investigates 1p36.3 telomere deletion in B-non-Hodgkin's lymphoma (NHL) patients with chronic HCV infection using fluorescence in situ hybridization (FISH) in relation to survival to assess Ki-67 antigen expression. A study group and a control group of 100 patients with B-NHL (50 HCV positive and 50 HCV negative) and 60 control bone marrow biopsies were subjected to FISH for the detection of 1P36.3 deletion and to immunohistochemical staining with Ki-67 antigens. 1p36.3 deletion by FISH was detected in 40% of the study group, and Ki-67 was expressed in approximately 74% of patients. A significant difference was found between positive and negative HCV patients in their overall survival, the qualitative expression of Ki-67 and the quantitative detection of 1p36.3 deletion by FISH. The overall survival was shorter with the presence of an 1p36 deletion by FISH and HCV positive. We concluded that the coexistence of Ki-67 positivity, HCV positivity and 1p36.3 deletion may contribute to infection-related cancers at the 1p36.3 locus. © 2014 John Wiley & Sons Ltd.

    In the present study, both post-irradiation DNA synthesis and G 2 phase accumulation were analyzed in lymphoblastoid cell lines (LCLs) and fibroblast cell strains derived from (Saudi) patients with non-Hodgkin's lymphoma (NHL), ataxia telangiectasia (AT), AT heterozygotes and normal subjects. A comparison of the percent DNA synthesis inhibition (assayed by 3 H-thymidine uptake 30 min after irradiation), and a 24 h post-irradiation G 2 phase accumulation determined by flow cytometry placed the AT heterozygotes and the NHL patients in an intermediate position between the normal subjects (with maximum DNA synthesis inhibition and minimum G 2 phase accumulation) and the AT homozygotes (with minimum DNA synthesis inhibition and maximum G 2 accumulation). The similarity between AT heterozygotes and the NHL patients with respect to the two parameters studied after irradiation was statistically significant. The data indicating a moderate abnormality in the control of cell cycle progression after irradiation in the LCLs and fibroblasts from NHL patients may explain the enhanced cellular and chromosomal radiosensitivity in these patients reported by us earlier. In addition to demonstrating a link between cell cycle abnormality and radiosensitivity as a possible basis for cancer susceptibility, particularly in the NHL patients, the present studies emphasized the usefulness of the assay for 24 h post-irradiation G 2 phase accumulation developed elsewhere in characterizing AT heterozygote-like cell cycle anomaly in cancer patients irrespective of whether they carried the AT gene or any other affecting the cell cycle

    In 1993, a case-control study by the Health and Safety Executive (HSE) assessed the risk of leukaemia and non-Hodgkin's lymphoma (LNHL) among children of fathers employed at the Sellafield nuclear installation in relation to paternal preconceptional irradiation (PPI). It concluded that the statistical association between risk of LNHL and PPI was confined to children born in the village of Seascale, where the dose-response was extremely high and very significant. In contrast, in 2002, a Cumbrian birth cohort study, investigating largely the same cases, concluded that this statistical association was not significantly different among children born inside and outside Seascale and estimated the dose-response inside Seascale to be much lower. This review makes a detailed comparison of the two studies, considering their design, data and analyses. The differences between their findings are due to: (i) differences in the distribution of offspring-years which are differential with respect to dose category and Seascale birth status, (ii) a non-Seascale high-dose case included in the Cumbrian but not the HSE study, (iii) differences between analyses using categorical and continuous PPI dose and (iv) the presence of Seascale controls with PPI over 200 mSv in the Cumbrian but not the HSE study

    We carried out a meta-analysis to explore the association between poultry and eggs consumption and non-Hodgkin lymphoma (NHL) risk according to the published observational studies. A search of databases was performed in MEDLINE and EMBASE from their inception to March 2015. We derived meta-analytic estimates using random-effects models, and assessed between-study heterogeneity using the Cochran's Q and I 2 statistics. We identified a total of nine case-control and three prospective cohort studies, including 11,271 subjects with NHL. The summary relative risks for high vs. low analyses were 1.04 (95% confidence intervals [CIs]: 0.86-1.27; p heterogeneity poultry consumption and 1.15 (95% CIs: 0.87-1.51; p heterogeneity poultry consumption, whereas no significant factors were responsible for the high heterogeneity among the studies on eggs consumption. Limited data suggested a null association between consumption of poultry and eggs and NHL subtypes. Findings from our meta-analysis indicate that consumption of poultry and eggs may be not related to NHL risk. © 2016 John Wiley & Sons Ltd.

    Neurolymphomatosis is a rare condition defined as an infiltration of nerves, nerve roots or nervous plexuses by haematological malignancy. Its diagnosis may sometimes be difficult with conventional imaging techniques. This paper aims to emphasize the importance of this entity and the role of (18)F-FDG PET/CT in this indication. We present the case of a 53-year-old male who complained of sharp pain in his right hip and right leg paresthesia after 2 years of complete remission from Non-Hodgkin's lymphoma. Physical examination and CT scan were negative and the lumbar MRI showed protrusion of L5-S1 disc. Physiotherapy, nonsteroid antiinflammatory drugs and steroids were inefficient. PET/CT was performed four months after the onset of the symptoms, revealing focal FDG uptake in the right S1 nerve root and linear FDG uptake along the right sacral plexus suggesting relapse. This was confirmed by histology. Copyright © 2013 Elsevier España, S.L. and SEMNIM. All rights reserved.
