According to the WHO-EORTC classification of cutaneous lymphomas, primary cutaneous marginal zone B-cell lymphoma are now well characterized. We report here a case of primary cutaneous marginal zone B-cell lymphoma in a 51 year-old man in which the diagnosis was made using both histology and immunopathology. The patient had no remarkable medical history, no history of either acute inflammation or insect bite, and presented with a 5 cm solitary asymptomatic erythematous firm, multinodular and infiltrated plaque on the back for 12 months. Histological examination and immunohistochemical study of a cutaneous biopsy provided a differential diagnosis between B cell lymphoma and lymphocytoma cutis. Full body work up revealed no signs of extracutaneous dissemination. The patient underwent surgical excision of the nodule. Histological examination showed a histological and immunophenotyping profile typical of primary cutaneous marginal zone B-cell lymphoma. The lesion was completely excised with clear margins and no recurrence occurred after a 12 month-follow-up period. Primary cutaneous marginal zone B-cell lymphoma are low-grade lymphomas that have an indolent course and a high tendency to recur. They should be differentiated from lymphocytoma cutis and from the other types of cutaneous B cell lymphomas that have a different course and prognosis.

There is no standard treatment for patients with gastric marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT lymphoma) who are resistant to, or ineligible for, anti-Helicobacter pylori (anti-HP) therapy. In this study, we investigated the activity of the rituximab, cyclophosphamide, vincristine and prednisone (R-CVP) regimen in patients with gastric MALT lymphoma. Patients were included provided they had untreated gastric MALT lymphoma (except for anti-HP therapy) and were resistant to, or ineligible for, anti-HP therapy. Treatment plan consisted of six to eight 21-day cycles of the R-CVP chemotherapy regimen. Toxicity, response, relapse and survival were evaluated. Twenty patients (12 women and 8 men) were included in the analyses with median age of 59 years. Thirteen patients (65%) had stage I tumours, and seven patients (35%) had stages II-IV tumours. The overall response rate was 100%, with 19 (95%) complete responses and one (5%) partial response. Regimen toxicity was mild and mainly hematological, and no cases of gastric bleeding or perforation occurred. After a median follow-up of 56.3 months, three patients had relapsed, and 19 patients remained alive (specific lymphoma survival 100%), of whom 17 had no evidence of disease. In our experience, the R-CVP regimen is a well-tolerated and effective treatment for patients with gastric MALT lymphoma who are resistant to, or ineligible for, anti-HP therapy.

Mucosa-associated lymphoid tissue (MALT) lymphoma is among the most common forms of extranodal lymphomas, but little is known about subcutaneous involvement in patients with non-primary cutaneous marginal zone lymphomas. Patients with MALT lymphoma diagnosed and treated at our institution between 1999 and 2010 were analyzed for subcutaneous deposits from MALT lymphoma diagnosed in another organ. Histological, clinical and genetic findings were assessed. Among 216 patients with MALT lymphoma, 12 had subcutaneous deposits from MALT lymphoma (5.5%). In two patients, these lesions were present at diagnosis, while they constituted the site of relapse at an interval between 5 to 144 months in the remaining cases. Interestingly, nine of the 12 patients with subcutaneous deposits had originally been diagnosed with MALT lymphoma of the ocular adnexa (total number=51; 20%), and the other three had MALT lymphoma in the breast (total number=5; 60%). None of the patients with gastric (n=86), salivary gland (n=32) or pulmonary (n=19) MALT lymphomas had subcutaneous involvement during a median follow-up time of 87 months (range; 4 to 119 months). Our data show that subcutaneous MALT lymphoma involvement is a rare event in patients with prior non-cutaneous extranodal marginal zone lymphoma. However, it seems to be almost exclusively associated with MALT lymphoma of the ocular adnexa and the breast, suggesting as yet undefined interactions between potentially embryonically related organ systems.

Purpose: Primary dural lymphoma is a rare intracranial lymphoma that almost always has a marginal zone histologic type and immunophenotype and often remains localized and is thus potentially curable with radiotherapy (RT) alone. The unusual location and histologic type of primary dural marginal zone lymphoma (PDMZL) distinguish it from primary central nervous system lymphoma and poses treatment dilemmas of technique, volume, and dose that have not been well addressed. We set out to analyze our recent experience in treating PDMZL and reviewed the limited published data available. Methods and Materials: Between 2002 and 2006, we treated 5 patients with localizedmore » PDMZL. Of these 5 patients, 3 had unilateral and 2 had bilateral/multifocal involvement, and 3 underwent subtotal tumor resection and 2 biopsy only. Whole brain RT was given before involved-field RT (IFRT) in 4 patients and 1 received IFRT alone. The median whole brain RT, IFRT, and total RT dose was 20, 12, and 30 Gy, respectively. The planning computed tomography scan was always fused with the post-gadolinium magnetic resonance imaging scan to assist in the IFRT volume determination. We also analyzed the published data from 27 additional patients. Results: The median follow-up was 34 months (range, 31-52). All obtained lasting local control. One patient developed a relapse in the soft tissue of the flank and additional systemic progression but no central nervous system recurrence. At last follow-up, no significant treatment-related neurotoxicity was detected. Conclusion: The results of our study have demonstrated that a combination of whole brain RT/IFRT or even low-dose IFRT alone provides excellent durable local control of PDMZL. This approach is potentially curative, possibly without significant neurotoxicity. Additional study and longer follow-up are needed to determine the appropriate RT dose and volume parameters for this rare, debilitating, and yet potentially curable lymphoma.« less

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) is a low-grade malignant lymphoma that appears frequently in the stomach, but other sites can also be involved: the intestinal tract, lungs, head, neck, skin, thyroid, breasts and liver. Recently, epidemiological evidences support the idea that there is an association between hepatitis C and B-cell non-Hodgkin lymphomas (that include MALT as a subtype). Primary non-Hodgkin lymphomas confi ned only to the liver are very rare (only 0.016% of all cases of all non-Hodgkin's lymphomas) and MALT is not the most frequent type. We present the case of a male patient, age 62, known with chronic hepatitis C, previously relapser a" er a 72 week treatment with peg-interferon alfa and ribavirin that was diagnosed at three years a" er the relapse with multiple focal liver lesions. One of the tumors was surgically removed and the histological exam performed demonstrated an extranodal marginal zone lymphoma with small B-cell with plasmacytoid diff erentiation confi ned only to the liver. Direct acting antiviral (DAA) therapy was started, but the virologic clearance was not obtained by week 10, leading to a change of DAA regimen at week 12. The antiviral therapy was continued until week 24. Imaging showed an increase in number and size of the focal lesions until week 12. At week 12 chemo- and immune-therapy was started with bendamustine and rituximab. A" erwards the evolution was favorable, the patient being now in complete remission and with undetectable viral load.

Blastic transformation (BT) of marginal zone lymphoma or mucosa-associated lymphoid tissue lymphoma has been mainly reported in the spleen and stomach. Primary cutaneous marginal zone lymphoma that undergoes BT is rare and not well documented. We describe 8 patients with blastic primary cutaneous marginal zone lymphoma and compare the clinical, pathologic, and molecular findings of these patients with 10 cases previously reported in the literature. The cases of blastic marginal zone lymphoma could be categorized into cases of de novo blastic marginal zone lymphoma and large-cell transformation arising in a background of a history of biopsy proven marginal zone lymphoma. The cases of de novo blastic marginal zone lymphoma occurred in elderly patients without any medical history. In each of the cases, the lesions were radiated, not treated, or treated with complete excision without any death due to lymphoma nor was there any evidence of extracutaneous dissemination. Large-cell transformation arising in background of marginal zone lymphoma typically occurred in patients who were younger; 2 of the 4 cases were immunocompromised. The clinical course in each of the cases was aggressive with 3 of the 4 patients succumbing to disseminated disease while 1 patient developed extracutaneous nodal disease. Phenotypically, there was an expression of CD5 in a total of 3 of the 8 cases and CD23 in 3 of the 8 cases. Commonality of B-cell clones was demonstrated in 2 cases where biopsies were available of both the less aggressive appearing marginal zone lymphoma and the transformed biopsies. Cytogenetic abnormalities associated with BT included a deletion of chromosome 7q in all cases tested. Large-cell transformation arising in a patient with a history of marginal zone lymphoma portends a worse prognosis, including death from disseminated disease, whereas a de novo presentation of blastic marginal zone lymphoma may define a clinical course similar to other forms of low

Purpose To evaluate the efficacy of radiotherapy (RT) for early-stage nodal and extranodal marginal zone lymphoma (MZL). Materials and methods Patients with stage I (n = 22) and stage II (n = 8) MZL, who were treated with RT were reviewed. The primary tumor localisation was in the orbita (n = 12), stomach (n = 8), head and neck other than the orbita (n = 8), breast (n = 1) and one case of marginal zone lymphoma of the skin (n = 1). The median radiotherapy dose was 40 Gy (5 to 45 Gy). Results The median follow-up time was 103 months. The 5-year overall survival and event-free survival rates were 85 ± 7% and 71 ± 9%, respectively. There was no infield recurrence. Recurrence occurred outside of the radiation field in six patients. The relapses were treated with salvage RT and had excellent local control (100%) at five years after salvage RT. Conclusions Localized extranodal MZL have an excellent prognosis following moderate-dose RT. RT is also an effective salvage therapy in cases of localized recurrence. Further clinical studies should evaluate the optimal dose for MZL. PMID:23281682

Emerging role of infectious etiologies in the pathogenesis of marginal zone B-cell lymphomas.

Zucca, Emanuele; Bertoni, Francesco; Vannata, Barbara; Cavalli, Franco

2014-10-15

Extranodal marginal zone B-cell lymphomas of the mucosa-associated lymphoid tissue (MALT) arise from lymphoid populations that are induced by chronic inflammation in extranodal sites. The most frequently affected organ is the stomach, where MALT lymphoma is incontrovertibly associated with a chronic gastritis induced by a microbial pathogen, Helicobacter pylori. Gastric MALT lymphoma therefore represents a paradigm for evaluating inflammation-associated lymphomagenesis, which may lead to a deeper understanding of a possible etiologic association between other microorganisms and nongastric marginal zone lymphomas. Besides infectious etiology, chronic inflammation caused by autoimmune diseases, such as Sjögren syndrome or Hashimoto thyroiditis, can also carry a significant risk factor for the development of marginal zone lymphoma. In addition to the continuous antigenic drive, additional oncogenic events play a relevant role in lymphoma growth and progression to the point at which the lymphoproliferative process may eventually become independent of antigenic stimulation. Recent studies on MALT lymphomas have in fact demonstrated genetic alterations affecting the NF-κB) pathway, a major signaling pathway involved in many cancers. This review aims to present marginal zone lymphoma as an example of the close pathogenetic link between chronic inflammation and tumor development, with particular attention to the role of infectious agents and the integration of these observations into everyday clinical practice.

In this study with prolonged follow up, we compared clinical outcome, including cause of death and incidence of second cancer, for patients with early stage extranodal marginal zone lymphoma (EMZL, 49 patients), nodal marginal zone lymphoma (NMZL, nine patients) and mantle cell lymphoma (MCL, 42 patients) with emphasis on potential benefit of radiotherapy. Radiotherapy was given to 40 patients with EMZL (nine had surgery only) and all NMZL patients. MCL patients received radiotherapy (17 patients), chemotherapy followed by radiotherapy (13 patients) or chemotherapy alone (12 patients). Compared to a matched control population no increased risk of second cancer or cardiovascular disease was observed. Radiotherapy alone was effective in EMZL and NMZL with low-relapse rates (20% and 33%) and a 10-year overall survival of 78% and 56%, respectively. High-relapse rate and inferior OS in MCL underline the need for extended staging with endoscopy and PET/CT and possibly for novel strategies.

Double-hit (DH) lymphoma, an extremely aggressive variant of B-cell lymphoma, is accompanied by chromosomal abnormalities leading to the activation of a few oncogenes, one of which is the c-MYC gene in conjunction with BCL2 or BCL6 gene rearrangements. There are most common cases of MYC/8q24 and BCL2/18q21 gene rearrangements (MYC/BCL-2 DH lymphoma). The tumor is characterized by an aggressive clinical course and a poor response to chemotherapy (CT). The median survival in patients with DH lymphomas varies from 4.5 to 18 months. Such patients are generally resistant to CHOP-21 and R-CHOP-21 therapy regimens. For the treatment of patients with DH lymphoma, the Hematology Research Center, Ministry of Health of the Russian Federation, chose an original BL-M-04 polychemotherapy (PCT) protocol in combination with rituximab, followed by autologous stem cell transplantation (allo-SCT). The paper describes the experience in successfully treating a patient with two hematologic tumors: 1) MYC/BCL-2 DH lymphoma with high-dose PCT cycles, followed by allo-SCT, and 2) a metachronously developed second tumor (acute myelomonoblastic leukemia (AMML)) with CT cycles, followed by auto-SCT. The incidence of tumors induced by the previous high-dose CT for aggressive lymphomas for 10 years is 0.7 to 10%. As a rule, the development of secondary AMML is preceded by a history of myelodysplastic syndrome (MDS); characteristic chromosomal abnormalities (deletions of the long arm of chromosomes 5 and 7) are detectable. In this case, the follow-up was 3 months before the development of AMML, during this period the patient was not found to have laboratory signs of MDS (anemia, thrombocytopenia) or chromosomal abnormalities associated with secondary MDS/AML. The presence of a leukemic stem cell is associated with the occurrence and development of hemoblastosis; that of the similar cell populations that may cause B-cell lymphomas remains uncertain. The described case may have defect in a

Marginal zone lymphoma (MZL) is a low-grade B-cell lymphoma derived from marginal zone B cells. Because of a lack of specific immunohistochemical markers, MZL is mainly diagnosed based on the cytological appearance and growth pattern of the tumor. Marginal zone B cells were recently shown to selectively express immunoglobulin superfamily receptor translocation-associated 1 (IRTA1), but the antibody used in that study is not commercially available. We therefore investigated the IRTA1 expression in nonneoplastic lymphoid tissues and 261 malignant lymphomas, examining the ability of a commercially available antibody to accurately diagnose MZL. Among 37 MZLs, 23 of 25 extranodal MZLs of mucosa-associated lymphoid tissue (MALT lymphomas), 3 of 6 splenic MZLs and 3 of 6 nodal MZLs were positive for IRTA1. Among the 98 diffuse large B-cell lymphomas, 33 were positive for IRTA1, including 1 of 38 follicular lymphomas, and all precursor B-lymphoblastic (2/2) and T-lymphoblastic (7/7) leukemia/lymphomas. Other mature B-cell and T-cell lymphomas, and Hodgkin lymphoma were negative for IRTA1. In MALT lymphoma, positive cells were detected mainly in intraepithelial and subepithelial marginal zone B cells. In 1 case of grade 3 follicular lymphoma, IRTA1 was also expressed in the area of large cell transformation. When tumors were classified as germinal center B cell-like (GCB) or non-GCB using the algorithm of Hans, positive expression of IRTA1 was correlated significantly with non-GCB diffuse large B-cell lymphomas (P < .05). These results demonstrated the ability of the commercially available IRTA1 antibody to distinguish MALT lymphoma from other low-grade B-cell lymphomas. Copyright © 2016 Elsevier Inc.

Primary cutaneous marginal zone B-cell lymphoma (PCMZL) is an indolent low grade B cell lymphoma of the skin, with lack of extracutaneous involvement at the time of diagnosis. Herein we report the case of a patient with rheumatoid arthritis (RA) who developed symmetrical PCMZL lesions on both ear lobes. Lesions occurring symmetrically on ear lobes are more specific for cutaneous lymphoid hyperplasia (CLH) and this kind of symmetrical localization hasn't been reported for PCMZL before. PCMZL is considered to arise from a background of reactive lymphoid hyperplasia and this case point out the concept of CLH and PCMZL spectrum. Association of marginal zone lymphoma with rheumatoid arthritis and resolution of lesions together with the resolution of symptoms due to rheumatoid arthritis after rituximab therapy is another interesting point for this case. To the best of our knowledge PCMZL associated with RA has not been reported previously.

A 55-year-old woman suffered from hemorrhagic tendency. She had severe thrombocytopenia without any hematological or coagulatory abnormalities, and a bone marrow examination revealed an increased number of megakaryocytes without any abnormal cells or blasts. No lymphadenopathy or hepatosplenomegaly was observed on computed tomography. She was initially diagnosed with immune thrombocytopenic purpura (ITP). None of the treatments administered for ITP produced a response. However, abnormal cells were eventually found during the third bone marrow examination. The pathological diagnosis was mature B-cell lymphoma. Rituximab-containing chemotherapy produced a marked increase in the patient's platelet count, and her lymphoma went into complete remission.

Marginal zone lymphomas (MZLs) are indolent disorders composed of 3 subtypes: extranodal marginal zone lymphoma (MALT), splenic marginal zone lymphoma (SMZL), and nodal marginal zone lymphoma (NMZL). Early-stage MALT is treated with radiotherapy or antibiotics, and advanced MALT and NMZL are managed with either watch and wait or chemotherapy. SMZLs are treated with splenectomy or rituximab. However, because these approaches have failed to cure patients with SMZL and NMZL, we have systematically used upfront chemotherapy for them, as well as for advanced MALT. We report the outcomes of this approach. A total of 44 patients with MZL were identified from our database and divided into 2 groups. Group 1 (22 with early-stage MALT) patients received either radiotherapy (n = 17) or antibiotics with or without surgery (n = 5). Group 2 included 9 patients with advanced MALT, 9 with SMZL, and 4 with NMZL. Group 2 was treated with FND-R (fludarabine 25 mg/m 2 on days 1 to 3, mitoxantrone 10 mg/m 2 on day 1, dexamethasone 20 mg on days 1 to 5, and rituximab 375 mg/m 2 on day 1; n = 14) or CHOP-R (cyclophosphamide 750 mg/m 2 on day 1, doxorubicin 50 mg/m 2 on day 1, vincristine 2 mg intravenous push on day 1, prednisone 100 mg/m 2 orally on days 1 to 5, rituximab 375 mg/m 2 on day 1; n = 8), followed by maintenance rituximab for 70%. All patients achieved complete remission, and only 2 patients in group 1 had developed a relapse at 70 and 75 months. Both relapses were stage I MALT that had initially been treated with radiotherapy. Both were salvaged with FND-R and remained free of disease at 27 and 39 months after the relapse. At 10 years, the failure-free survival for the 44 patients was 80% and the overall survival was 100%. None of the patients in group 2 developed a relapse. The long-term toxicities have been acceptable. The excellent responses using upfront chemotherapy for MZL suggests that this disorder is curable. Our results should be confirmed in a prospective trial

Canine nodal marginal zone lymphoma (nMZL) is classified as an indolent lymphoma. Such lymphomas are typified by low mitotic rate and slow clinical progression. While the clinical behaviour of canine splenic MZL has been described, characterized by an indolent course and a good prognosis following splenectomy, there are no studies specifically describing nMZL. The aim of this study was to describe the clinical features of and outcome for canine nMZL. Dogs with histologically confirmed nMZL undergoing a complete staging work-up (including blood analysis, flow cytometry [FC] on lymph node [LN], peripheral blood and bone marrow, imaging, histology and immunohistochemistry on a surgically removed peripheral LN) were retrospectively enrolled. Treatment consisted of chemotherapy or chemo-immunotherapy. Endpoints were response rate (RR), time to progression (TTP) and lymphoma-specific survival (LSS). A total of 35 cases were enrolled. At diagnosis, all dogs showed generalized lymphadenopathy. One-third was systemically unwell. All dogs had stage V disease; one-third also had extranodal involvement. The LN population was mainly composed of medium-sized CD21+ cells with scant resident normal lymphocytes. Histology revealed diffuse LN involvement, referring to "late-stage" MZL. Median TTP and LSS were 149 and 259 days, respectively. Increased LDH activity and substage b were significantly associated with a shorter LSS. Dogs with nMZL may show generalized lymphadenopathy and an advanced disease stage. Overall, the outcome is poor, despite the "indolent" designation. The best treatment option still needs to be defined. © 2017 John Wiley & Sons Ltd.

To describe the progression-free survival (PFS) time and overall survival time (OST) of dogs with T-cell lymphoma or hypercalcemic lymphoma treated with L-asparaginase and mechlorethamine, vincristine, prednisone, procarbazine (MOPP). Fifty dogs with T-cell lymphoma, hypercalcemic lymphoma, or both treated at 3 referral veterinary hospitals. Retrospective study. Case were selected based on histologic or cytologic diagnosis of lymphoma; presence of the T-cell phenotype, presence of hypercalcemia or both; and absence of previous chemotherapy. The T-cell phenotype was determined by flow cytometry, immunocytochemistry, immunohistochemistry, or polymerase chain reaction of antigen receptor rearrangement. The overall response rate was 98% (78% complete response, 20% partial response). The median PFS for the entire study population was 189 days with 25% PFS at 939 days. The median OST for the entire study population was 270 days with 25% surviving 939 days. Twenty percent of the dogs required hospitalization for treatment related complications. L-Asp/MOPP chemotherapy might result in longer PFS and OST for dogs with multicentric T-cell lymphoma, dogs with hypercalcemic lymphoma or both, than achieved with CHOP.

The mechanisms promoting malignant transformation from chronic Helicobacter pylori-gastritis to gastric extranodal marginal zone lymphoma (MALT lymphoma) are insufficiently characterized. This follow-up study aimed to validate candidate microRNAs (miRs) in the process of neoplastic transformation. MicroRNA expression signatures (n=20) were generated for a total of 60 cases of gastric lesions ranging from Wotherspoon 0-5 employing a quantitative real-time polymerase chain reaction (PCR) approach. Morphological and immunohistochemical characterization of the cohort was supplemented by PCR-based immunoglobulin heavy chain recombination studies. Quantitative expression of miR-150, miR-142.3p, miR-375 and miR-494 was significantly de-regulated in samples from MALT lymphoma compared to those from gastritis. The previously reported up-regulation of miR-150 in marginal zone lymphoma of MALT type was verified in an independent cohort of lymphoma samples employing a modified methodology. This further substantiates the role of miR-150 as a potential oncomiR in MALT lymphoma.

Hodgkin Lymphoma: Diagnosis and Treatment.

Ansell, Stephen M

2015-11-01

Hodgkin lymphoma is a rare B-cell malignant neoplasm affecting approximately 9000 new patients annually. This disease represents approximately 11% of all lymphomas seen in the United States and comprises 2 discrete disease entities--classical Hodgkin lymphoma and nodular lymphocyte-predominant Hodgkin lymphoma. Within the subcategorization of classical Hodgkin lymphoma are defined subgroups: nodular sclerosis, mixed cellularity, lymphocyte depletion, and lymphocyte-rich Hodgkin lymphoma. Staging of this disease is essential for the choice of optimal therapy. Prognostic models to identify patients at high or low risk for recurrence have been developed, and these models, along with positron emission tomography, are used to provide optimal therapy. The initial treatment for patients with Hodgkin lymphoma is based on the histologic characteristics of the disease, the stage at presentation, and the presence or absence of prognostic factors associated with poor outcome. Patients with early-stage Hodgkin lymphoma commonly receive combined-modality therapies that include abbreviated courses of chemotherapy followed by involved-field radiation treatment. In contrast, patients with advanced-stage Hodgkin lymphoma commonly receive a more prolonged course of combination chemotherapy, with radiation therapy used only in selected cases. For patients with relapse or refractory disease, salvage chemotherapy followed by high-dose treatment and an autologous stem cell transplant is the standard of care. For patients who are ineligible for this therapy or those in whom high-dose therapy and autologous stem cell transplant have failed, treatment with brentuximab vedotin is a standard approach. Additional options include palliative chemotherapy, immune checkpoint inhibitors, nonmyeloablative allogeneic stem cell transplant, or participation in a clinical trial testing novel agents.

The concept of unidirectional differentiation of the haematopoietic stem cell has been challenged after recent findings that human B cell progenitors and even mature B cells can be reprogrammed into histiocytic/dendritic cells by altering expression of lineage-associated transcription factors. The conversion of mature B cell lymphomas to Langerhans cell neoplasms is not well documented. Three previous reports have described clonally related follicular lymphoma and Langerhans cell tumours, whereas no case has been published of clonally related marginal zone lymphoma and Langerhans cell sarcoma. We describe the case of a 77-year-old patient who developed a Langerhans cell sarcoma and 6 years later a nodal marginal zone lymphoma. Mutation status examination showed 100 % gene identity to the germline sequence, suggesting direct trans-differentiation or dedifferentiation of the nodal marginal zone lymphoma to the Langerhans cell sarcoma rather than a common progenitor. We found inactivation of paired box 5 (PAX-5) in the lymphoma cells by methylation, along with duplication of part of the long arm of chromosomes 16 and 17 in the sarcoma cells. The absence of PAX-5 could have triggered B cells to differentiate into macrophages and dendritic cells. On the other hand, chromosomal imbalances might have activated genes involved in myeloid lineage maturation, transcription activation and oncogenesis. We hypothesize that this occurred because of previous therapies for nodal marginal zone lymphoma. Better understanding of this phenomenon may help in unravelling the molecular interplay between transcription factors during haematopoietic lineage commitment and may expand the spectrum of clonally related mature B cell neoplasms and Langerhans cell tumours.

Splenic marginal zone lymphoma with or without villous lymphocytes (SLVL/SMZL) is an indolent lymphoma that typically affects elderly patients and that has a median survival >10 years. It presents with marked splenomegaly. Treatment is required in symptomatic cases. Splenectomy remains one of the first-line options in patients fit for surgery. The best pharmacological strategy has not yet been identified for poor surgical risk cases. Among different possible chemotherapeutic approaches, purine analogs, alone or in association with Rituximab, seem to be a valid therapeutic choice. Fifty SMZL patients were treated with Cladribine ± anti-CD20 monoclonal antibody. Forty-seven of 50 patients were evaluable for response. ORR was 87%: 24 of 47 patients (51%) achieved a complete hematological response (CR), 17 of 47 (36%) a partial response (PR) and 6 (13%) resulted unresponsive. Interestingly, 15 of 24 cases (62%) in CR achieved also a molecular remission. After a median follow-up of 48 months, 7 of 41 responsive cases relapsed and the 5-year PFS was 80%. These data confirm the efficacy of this schedule emphasizing the impact of minimal residual disease even in the outcome of SMZL patients.

Although primary mediastinal large B-cell lymphoma and classic Hodgkin lymphoma of nodular sclerosis type are distinct disease, they share several clinical characteristics and biologic features. However, there are mediastinal lymphomas that not fit in either category. These types of lymphomas are recognized as mediastinal gray zone lymphomas. Gray zone lymphomas are lymphatic tumors that cannot be assigned to a defined lymphoma entity due to morphological, clinical, or genetic reasons. In this report, we present a case of a 22 year-old-Hispanic-female diagnosed with B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Hodgkin lymphoma.

Antisecretory medication is associated with decreased Helicobacter pylori detection in gastric marginal zone lymphoma.

PubMed

Schaberg, Kurt B; Evans, Mark F; Wilcox, Rebecca; Lewis, Michael R

2015-12-01

Helicobacter pylori status influences the prognosis and management of gastric extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma), so accurate determination of H pylori status is of clinical importance. The low rate of histologic H pylori positivity among gastric MALT lymphoma cases at our institution prompted investigation for possible causes. A case series of 24 patients as having gastric MALT lymphoma (with no diffuse large B-cell component) in a tertiary care setting between 1997 and 2010 was identified, and clinical records were reviewed. Immunohistochemical staining for H pylori and BCL10 was performed. This study received institutional review board approval (protocol number M13-033). Thirty-nine percent of cases (9/23) were H pylori positive by histology, and 4 additional patients had positive serologic results; overall, 57% of cases (13/23) were positive for H pylori. Treatment with antisecretory medications was associated with a lower likelihood of histologic positivity (13% among treated patients vs 75% among untreated; P = .04). Nuclear localization of BCL10 was seen in 2 cases and was not associated with H pylori status. Antisecretory medications decrease the likelihood of histologic detection of H pylori in gastric MALT lymphoma cases. Incorporation of results of serologic or other testing is needed to ensure correct classification with respect to H pylori status. Copyright © 2015 Elsevier Inc. All rights reserved.

Successful treatment of tracheal lymphoma in a Siamese cat.

2017-01-01

An 8-year-old female spayed Siamese indoor cat presented with a 3 week history of inspiratory dyspnoea, stridor and open-mouth breathing after exercise. Laryngoscopy, tracheoscopy, bronchoscopy and retroflexed nasopharyngoscopy were performed, and identified a multilobulated intraluminal mass within the trachea. Brush cytology was performed on the mass but was inconclusive in providing a definitive diagnosis. A CT scan of the neck failed to identify an obvious intraluminal mass and was negative to contrast uptake. Surgery was performed and seven rings of the trachea were removed to enable the complete excision of the mass. Histopathology of the excised mass was consistent with B cell lymphoma. After surgery, chemotherapy treatment was started. At the time of writing, 20 months since diagnosis, the cat remained clinically well, with no clinical signs or recurrence of macroscopic disease on endoscopic evaluation. Upper airway endoscopy was considered to be an essential diagnostic tool in this case presenting with signs of upper respiratory dyspnoea. Moreover, combined surgery and chemotherapy were considered effective treatments and positively affected the long-term prognosis of this patient.

2018-01-01

Extranodal marginal zone lymphoma of the central nervous system (CNS EMZBL) is a rare disease. We present a review of the literature and describe its presentation, differential diagnosis, treatment options, and outcomes. Systematic search of PubMed, Medline, and Embase databases via the Ovid engine for primary articles and case reports yielded 37 unduplicated peer-reviewed articles of CNS EMZBL. We identified 69 cases in these articles and 1 unreported case at our institution, which were included for this review's analysis. Median age at diagnosis was 55 years (range, 18-78 years), with a female preponderance of 77% (n = 54). Most common presenting symptoms were headache in 43% (n = 30), seizures in 31% (n = 22), and visual defects in 27% (n = 19). The most common treatment modalities were localized therapies, which were provided to 67% (n = 47) of cases. These included radiotherapy in 27% (n = 19), radiotherapy with surgery in 24% (n = 17), and surgery alone in 16% (n = 11). Ninety percent (n = 63) of patients had a median follow-up of 23 months. Complete remission was experienced by 77% (n = 49) patients, and 22% (n = 14) were alive with disease. Three patients had evidence of relapse, and one patient died. CNS EMZBL is an indolent, low-grade, radiosensitive lymphoma with good treatment outcomes and prognosis. It is an important differential to consider in extra-axial dural-based masses. Individualized management plans, with preference given to localized treatment options, should be considered after factoring in the site and extent of disease, its resectability, and the expected adverse effects of systemic therapy.

Multimodality Treatment of Gastric Lymphoma.

PubMed

Ikoma, Naruhiko; Badgwell, Brian D; Mansfield, Paul F

2017-04-01

Gastric lymphoma is rare, accounting for 3% of gastric neoplasms and 10% of lymphomas. Treatment should be stratified based on histologic type, stage, Helicobacter pylori infection, and t(11;18) translocation status. Surgery is no longer a mainstay for treatment and should be reserved for rare situations such as perforation, fistula formation, and severe bleeding. Multimodal treatment, including H pylori eradication, radiation therapy, chemotherapy, and immunotherapy, should be provided as appropriate and can result in excellent outcomes.

2014-01-01

An 81-year-old man was admitted to our hospital due to dyspnea in July 2008. A physical examination revealed marked splenomegaly, and the results of laboratory tests were as follows: hemoglobin (Hb)=7.0 g/dL, Ret=6.4%, WBC=24,100/μL (Ly: 20,003/μL), indirect bilirubin=3.6 mg/dL, LDH=232 IU/L. The cold agglutinin titer was 1 : 8,192, and a direct antiglobulin test was positive. A PET scan showed abnormal accumulation in the spleen and bone marrow. A bone marrow aspirate examination and biopsy demonstrated diffuse involvement of abnormal lymphocytes that were found to be positive for CD20 and negative for CD5, CD10, and cyclin D1. The immunoglobulin genes were clonally rearranged. Based on these findings, splenic marginal zone B-cell lymphoma (SMZL) associated with cold agglutinin disease (CAD) was diagnosed. Because the patient refused splenectomy, he was treated with four cycles of rituximab therapy (375 mg/kg, once a week). The Hb level and lymphocyte count subsequently normalized and the splenomegaly resolved. One year later, he relapsed and was again treated with rituximab therapy with complete remission. CAD accompanied by SMZL is very rare. Rituximab may be chosen as an alternative and effective therapeutic option in patients with SMZL-particularly those with autoimmune hemolytic anemia.

Splenic marginal zone lymphoma (SMZL) accounts for less than 2% of all non-Hodgkin lymphomas. We identified 107 cases diagnosed with SMZL between 1985 and 2012 from the British Columbia Cancer Agency Centre for Lymphoid Cancer and Lymphoma Pathology Databases. Patient characteristics were: median age 67 years (range 30-88), male 40%, stage IV 98%, splenomegaly 93%, bone marrow involvement 96%, peripheral blood involvement 87%. As initial treatment, 52 underwent splenectomy (10 with chemotherapy), 38 chemotherapy alone (21 chemoimmunotherapy containing rituximab, 1 rituximab alone), two antivirals for hepatitis C, and 15 were only observed. The 10-year overall survival for first-line splenectomy versus chemotherapy was 61% and 42%, respectively [Hazard Ratio (HR) 0·48, 95% confidence interval (CI) 0·26-0·88, P = 0·017]. The 10-year failure-free survival (FFS) after first-line splenectomy vs chemotherapy was 39% and 14%, respectively (HR 0·48, 95% CI 0·28-0·80, P = 0·004). Among the 38 patients who received first-line chemotherapy, FFS was similar between those receiving rituximab (n = 22) and those who did not (n = 16) (HR 0·64, 95% CI 0·31-1·34, P = 0·238). Fifteen patients transformed to aggressive lymphoma with median time to transformation of 3·5 years (range 6 months to 12 years) and the 10-year transformation rate was 18%. In conclusion, splenectomy remains a reasonable treatment for patients with SMZL. © 2015 John Wiley & Sons Ltd.

Long-term follow-up of gastric lymphoma after stomach conserving treatment.

PubMed

Fischbach, W

2010-02-01

The therapeutic strategy in gastric lymphoma has completely changed over the last two decades. This change is mainly characterised by the abandonment of surgery in favour of conservative therapies and the introduction of Helicobacter pylori eradication therapy. It became evident that conservative treatment with radiation and/or chemotherapy is at least as effective as surgical resection and additionally offers the advantage of stomach preservation and better quality of life. The therapeutic goal is undoubtedly complete remission of the lymphoma as a necessary basis for cure of the disease. Both radiotherapy and chemotherapy have a high curative potential in gastric MALT lymphoma and diffuse large B-cell lymphoma (DLBCL), respectively. An open question is the additional benefit of radiation following Rituximab-CHOP chemotherapy in DLBCL. In patients with gastric MALT lymphoma of stage I H. pylori eradication offers complete remission rates of up to 80% with excellent long-term prognosis and a real chance of cure. Patients with MALT lymphoma of stage II and those with DLBCL of stage I may also respond to eradication therapy in the individual case. It also emerged recently that there is no need for any oncological therapy in patients revealing minimal histological residuals after successful H. pylori eradication. A watch-and-wait strategy is the adequate management of this condition. In summary, therapy of gastric lymphoma is nowadays individualised with lymphoma type, stage, and H. pylori status as the determinants of the choice of treatment. Efficacy and quality of life are strong arguments for a definite conservative approach encompassing H. pylori eradication, radiation and chemotherapy. 2010 Elsevier Ltd. All rights reserved.

Refractory Hodgkin lymphoma.

Despite the advances in the treatment of Hodgkin Lymphoma, patients with refractory disease still have a poor prognosis. Hodgkin Lymphoma can be refractory at first diagnosis or might become refractory later in the course of treatment. Both situations represent a therapeutic challenge. Intensified chemotherapy with BEACOPP escalated has been evaluated in early unfavourable and advanced Hodgkin Lymphoma and led to an improved tumour control and reduced rates of refractory disease. Furthermore, there is growing evidence for the role of tandem autologous transplant in breaking refractory disease. For patients relapsing after autologous transplant, more recent analyses have reported outcome and defined risk factors. The antibody drug conjugate brentuximab vedotin is a new, highly effective therapeutic option for these patients. Dose-reduced allogeneic transplant is a therapeutic alternative for patients relapsing after autologous transplant, but induction of a remission is the prerequisite for a successful allogeneic transplant. Brentuximab vedotin has been evaluated as a bridge to allogeneic transplant for patients refractory to conventional treatment. Recent therapeutic advances have improved the prognosis of Hodgkin Lymphoma by prevention or successful treatment of refractory disease. The use of new drugs such as brentuximab vedotin will hopefully further increase the cure rates.

Splenectomy is considered as one of the first-line treatments for symptomatic patients with splenic marginal zone lymphoma (SMZL). Between 1997 and 2012, 100 hepatitis C virus-negative patients with SMZL were treated by splenectomy as first-line treatment. At 6 months, all patients but three recovered from all cytopenias. The median lymphocyte count at 6 months and 1 year was 11.51 × 10(9)/L and 6.9 × 10(9)/L, respectively. Median progression-free survival (PFS) was 8.25 years. The 5-year and 10-year overall survival (OS) rates were 84% and 67%, respectively. Histological transformation occurred in 11% of patients, and was the only parameter significantly associated with a shorter time to progression (p = 0.0001). Significant prognostic factors for OS were age (p = 0.0356) and histological transformation (p = 0.0312). In this large retrospective cohort, we confirmed that splenectomy as first-line treatment in patients with SMZL corrected cytopenias and lymphocytosis within the first year and was associated with a good PFS.

Purpose: To determine the factors associated with the use of radiation therapy and associated survival outcomes in early-stage marginal zone lymphoma of the mucosa-associated lymphoid tissue (MALT). Methods and Materials: We extracted data on adult patients with stage I/II MALT lymphoma diagnoses between 1998 and 2010 recorded in the Surveillance, Epidemiology, and End Results (SEER) database. We studied factors associated with radiation therapy administration in a logistic regression model and described the cumulative incidence of lymphoma-related death (LRD) according to receipt of the treatment. The association of radiation therapy with survival was explored in multivariate models with adjustment for immortalmore » time bias. Results: Of the 7774 identified patients, 36% received radiation therapy as part of the initial course of treatment. Older patients; black or Hispanic men; white, Hispanic, and black women; and socioeconomically disadvantaged and underinsured patients had a significantly lower chance of receiving radiation therapy. Radiation therapy administration was associated with a lower chance of LRD in most sites. In cutaneous, ocular, and salivary MALT lymphomas, the 5-year estimate of LRD after radiation therapy was 0%. The association of radiation therapy with overall survival in different lymphoma sites was heterogeneous, and statistically significant in cutaneous (hazard ratio 0.45, P=.009) and ocular (hazard ratio 0.47, P<.0001) locations after multivariate adjustment. Conclusions: Demographic factors are associated with the use of radiation therapy in MALT lymphoma. Clinicians should be sensitive to those disparities because the administration of radiation therapy may be associated with improved survival, particularly in cutaneous and ocular lymphomas.« less

Helicobacter pylori eradication therapy has been used as a first-line treatment for H. pylori-positive gastric mucosa-associated lymphoid tissue (MALT) lymphoma. However, the management strategy for H. pylori-negative MALT lymphoma remains controversial. Therefore, the aim of this study was to examine the success rate of each treatment option for H. pylori-positive and H. pylori-negative gastric MALT lymphomas. In total, 57 patients with gastric MALT lymphoma diagnosed between December 2000 and June 2012 were enrolled in the study. The treatment responses were compared between H. pylori-positive and H. pylori-negative gastric MALT lymphomas. Of the 57 patients, 43 (75%) had H. pylori infection. Forty-eight patients received H. pylori eradication as a first-line treatment, and complete remission was achieved in 31 of the 39 patients (80%) with H. pylori-positive MALT lymphoma and in five (56%) of the nine patients with H. pylori-negative MALT lymphoma; no significant difference was observed between the groups (p=0.135). The other treatment modalities, including radiation therapy, chemotherapy, and surgery, were effective irrespective of H. pylori infection status, with no significant difference in the treatment response between H. pylori-positive and H. pylori-negative MALT lymphomas. H. pylori eradication therapy may be considered as a first-line treatment regardless of H. pylori infection status.

2012-01-01

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) lymphoma is a mature B-cell neoplasm that typically follows an indolent clinical course. Amyloid deposition associated with MALT lymphoma is uncommon. We describe the clinical and pathologic features of 20 cases of MALT lymphoma and associated amyloid deposition across diverse primary sites. Frozen section immunofluorescence performed on 4 cases suggests that these deposits are a localized form of AL amyloid. Clinical follow-up was available for 15 patients. Amyloid deposits distant from the initial site occurred in 5 cases, always at sites also involved by the underlying lymphoma. No definitive evidence of systemic amyloidosis affecting the heart, kidneys, or liver was present in any patient. Given the generally indolent clinical behavior of MALT lymphomas with associated amyloid, we do not recommend extensive follow-up testing for systemic amyloidosis or more aggressive therapy than would be indicated for other MALT lymphomas of similar clinical stage.

Emerging biological insights and novel treatment strategies in primary mediastinal large B-cell lymphoma.

While primary mediastinal large B-cell lymphoma (PMBCL) is considered to be a subtype of diffuse large B-cell lymphoma, it is a distinct clinicopathologic entity, with clinical and biological features closely resembling nodular sclerosing Hodgkin lymphoma. Recent studies have highlighted the shared biology of these two entities and identified novel critical pathways of lymphomagenesis, including the presence of distinct mutations. Mediastinal grey zone lymphomas with features in between PMBCL and nodular sclerosing Hodgkin lymphoma have been described as the missing link between the two parent entities. While the standard therapeutic approach to PMBCL has been immunochemotherapy followed by mediastinal radiation, strategies that obviate the need for radiation and thus eliminate its long-term toxicities have recently been developed. The identification of novel targets in PMBCL and mediastinal grey zone lymphomas have paved the way for testing of agents such as small molecule inhibitors of Janus kinase pathways and immune checkpoint inhibitors. Future directions in these diseases should focus on combining effective novel agents with immunochemotherapy platforms. Published by Elsevier Inc.

Molecular pathogenesis of splenic and nodal marginal zone lymphoma.

PubMed

Spina, Valeria; Rossi, Davide

Genomic studies have improved our understanding of the biological basis of splenic (SMZL) and nodal (NMZL) marginal zone lymphoma by providing a comprehensive and unbiased view of the genes/pathways that are deregulated in these diseases. Consistent with the physiological involvement of NOTCH, NF-κB, B-cell receptor and toll-like receptor signaling in mature B-cells differentiation into the marginal zone B-cells, many oncogenic mutations of genes involved in these pathways have been identified in SMZL and NMZL. Beside genetic lesions, also epigenetic and post-transcriptional modifications contribute to the deregulation of marginal zone B-cell differentiation pathways in SMZL and NMZL. This review describes the progress in understanding the molecular mechanism underlying SMZL and NMZL, including molecular and post-transcriptional modifications, and discusses how information gained from these efforts has provided new insights on potential targets of diagnostic, prognostic and therapeutic relevance in SMZL and NMZL.

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.

Febuxostat is an orally administered selective inhibitor of xanthine oxidase approved for the treatment of gout and prevention of tumor lysis syndrome. It is a relatively safe medication. Hypersensitivity reactions associated with the use of febuxostat are quite rare with only one reported case of DRESS syndrome. Recently, two case reports of rhabdomyolysis following the initiation of febuxostat were published. We hereby present the first case of rhabdomyolysis with hypereosinophilia following the administration of febuxostat to a 50-year-old patient newly diagnosed with marginal zone lymphoma. Three weeks after the initiation of febuxostat for tumor lysis syndrome prophylaxis, the patient presented with generalized weakness, diffuse myalgia and low-grade fever. Initial studies showed creatinine kinase level of 4471, hypereosinophilia of 1900/mm 3 , and LDH of 2691. All infectious and autoimmune diseases were ruled out. TSH level was normal. Muscle biopsy showed myonecrosis in addition to an eosinophilic inflammatory infiltrate in the endomysium and perimysium. Discontinuation of febuxostat led to prompt symptom resolution and normalization of blood tests eight days later. Copyright © 2016 Société française de rhumatologie. Published by Elsevier SAS.

CD79B and MYD88 Mutations in Splenic Marginal Zone Lymphoma

PubMed Central

Trøen, Gunhild; Warsame, Abdirashid; Delabie, Jan

2013-01-01

The mutation status of genes involved in the NF-κB signaling pathway in splenic marginal zone lymphoma was examined. DNA sequence analysis of four genes was performed: CD79A, CD79B, CARD11, and MYD88 that are activated through BCR signaling or Toll-like and interleukin signaling. A single point mutation was detected in the CD79B gene (Y196H) in one of ten SMZL cases. Additionally, one point mutation was identified in the MYD88 gene (L265P) in another SMZL case. No mutations were revealed in CD79A or CARD11 genes in these SMZL cases. Neither were mutations detected in these four genes studied in 13 control MZL samples. Interestingly, the two cases with mutations of CD79B and MYD88 showed increased numbers of immunoblasts spread among the smaller and typical marginal zone lymphoma cells. Although SMZL shows few mutations of NF-κB signaling genes, our results indicate that the presence of these mutations is associated with a higher histological grade. PMID:23378931

Infectious Aetiology of Marginal Zone Lymphoma and Role of Anti-Infective Therapy

PubMed Central

Perrone, Salvatore; D’Elia, Gianna Maria; Annechini, Giorgia; Pulsoni, Alessandro

2016-01-01

Marginal zone lymphomas have been associated with several infectious agents covering both viral and bacterial pathogens and in some cases a clear aetiological role has been established. Pathogenetic mechanisms are currently not completely understood. However, the role of chronic stimulation of the host immune response with persistent lymphocyte activation represents the most convincing explanation for lymphoproliferation. Gastric MALT lymphoma is strictly associated with Helicobacter pylori infection and various eradicating protocols, developed due to increasing antibiotic resistance, represent the first line therapy for gastric MALT. The response rate to eradication is good with 80% of response at 1 year; this finding is also noteworthy because it recapitulates cancer cured only by the antibacterial approach and it satisfies the Koch postulates of causation, establishing a causative relationship between Hp and gastric MALT lymphoma. Patients with chronic HCV infection have 5 times higher risk to develop MZL, in particular, an association with splenic and nodal MZL has been shown in several studies. Moreover, there is evidence of lymphoma regression after antiviral therapy with interferon+ribavirin, thus raising hope that newly available drugs, extremely efficient against HCV replication, could improve outcome also in HCV-driven lymphomas. Another case-study are represented by those rare cases of MZL localized to orbital fat and eye conjunctivas that have been associated with Chlamydophila psittaci infection carried by birds. Efficacy of antibacterial therapy against C. psittaci are conflicting and generally poorer than gastric MALT. Finally, some case reports will cover the relationship between primary cutaneous B-cell Lymphomas and Borrelia Burgdorferi. PMID:26740867

Recent advances in understanding the biology of marginal zone lymphoma

PubMed Central

Zucca, Emanuele

2018-01-01

There are three different marginal zone lymphomas (MZLs): the extranodal MZL of mucosa-associated lymphoid tissue (MALT) type (MALT lymphoma), the splenic MZL, and the nodal MZL. The three MZLs share common lesions and deregulated pathways but also present specific alterations that can be used for their differential diagnosis. Although trisomies of chromosomes 3 and 18, deletions at 6q23, deregulation of nuclear factor kappa B, and chromatin remodeling genes are frequent events in all of them, the three MZLs differ in the presence of recurrent translocations, mutations affecting the NOTCH pathway, and the transcription factor Kruppel like factor 2 ( KLF2) or the receptor-type protein tyrosine phosphatase delta ( PTPRD). Since a better understanding of the molecular events underlying each subtype may have practical relevance, this review summarizes the most recent and main advances in our understanding of the genetics and biology of MZLs.

Abstract Rationale: Primary lymphomas of the uterine cervix are a rare disease. They are often misdiagnosed because of their rarity and because they can be easily confused with a squamous cell carcinoma of the cervix, as they are usually presented as exophytic mass with vaginal bleeding as their most common symptoms. Nevertheless, considering that both the prognosis and the treatment are completely different between them, differential diagnosis should be taken into account. Patient concerns: A case of a 51-year-old woman with a primary diffuse large B-cell lymphoma of the cervix is presented. Diagnoses: Diagnosis of this tumor was a challenge for pathologists and clinicians, as four biopsies were needed to achieve a final diagnosis. Interventions: Patient was successfully treated with combined Rituximab and chemotherapy (R-CHOP) alone. Outcomes: Complete remission, confirmed through biopsy, was reached after six courses of chemotherapy. At 2-years follow up, patient is alive and free of disease. Lessons: Considering that the prognosis and treatment of primary malignant lymphoma of the cervix are completely different than that of the squamous cell carcinoma, awareness of this disease should be considered in the differential diagnosis.

Current developments in the treatment of early-stage classical Hodgkin lymphoma.

PubMed

Borchmann, Sven; von Tresckow, Bastian; Engert, Andreas

2016-09-01

After presenting the current treatment recommendations for early-stage Hodgkin lymphoma, we give an overview on recently published clinical trials in this setting. Furthermore, the potential influence of current trials on the treatment of early-stage Hodgkin lymphoma and integration of newly emerging drugs into treatment protocols will be discussed. Trials attempting treatment de-escalation and omission of radiotherapy on the basis of early interim PET-scans have been disappointing so far, but results of some large trials employing this strategy are still awaited. In contrast, a more defensive strategy of starting treatment with less aggressive doxorubicine, bleomycin, vinblastine, dacarbazine (ABVD) chemotherapy and intensifying treatment in early interim PET-positive patients has shown encouraging results. New drugs such as brentuximab vedotin and immune checkpoint inhibitors have shown promising results in relapsed and refractory Hodgkin lymphoma. Clinical trials of brentuximab vedotin in early-stage Hodgkin lymphoma have been initiated. Additionally, biomarker-based treatment de-escalation might be a possible route for future improvements. The challenge for future clinical research in early-stage Hodgkin lymphoma is to continue to cure the majority of patients with first-line treatment while reducing long-term toxicity. New strategies to achieve that goal are currently being developed and will further refine treatment of early-stage Hodgkin lymphoma.

Nodal marginal zone lymphoma (NMZL) is a rare type of B-cell non-Hodgkin lymphoma. This study assessed the clinical features of 56 patients with NMZL in comparison to 46 patients with follicular lymphoma (FL). Patients with NMZL and FL had a largely similar clinical presentation, but patients with FL had a higher disease stage at presentation, more frequent abdominal lymphadenopathy and bone marrow involvement, and showed more common transformation into diffuse large B-cell lymphoma (DLBCL) during the course of disease. Overall survival and event-free survival were similar for patients with NMZL and FL, but factors associated with worse prognosis differed between the two groups. Transformation into DLBCL was associated with a significantly poorer outcome in both groups, but the phenotypes were different: DLBCL arising in FL was mainly of germinal center B-cell phenotype, whereas DLBCL arising in NMZL was mainly of non-germinal center B-cell phenotype.

Tyrosine kinase inhibitors (TKIs) are standard therapy for chronic myeloid leukemia (CML). However, the effects of these agents on mature B cell lymphoma are not well known. We describe a 50-year-old man who was diagnosed with CML in the chronic phase and treated with imatinib. After 3 years of imatinib therapy that achieved a complete cytogenetic response of CML, he developed Philadelphia-negative follicular lymphoma (FL). Rituximab monotherapy induced a partial response of FL, and he subsequently achieved a major molecular response (MMR) of CML. Three years later, however, the MMR was lost, followed by the progression of FL. Imatinib was switched to nilotinib for the treatment of CML, while we chose watchful waiting for FL. He achieved MMR again under treatment with nilotinib for 8 months including one month of substitutional use of dasatinib due to adverse events, but thereafter nilotinib was switched to bosutinib due to hyperbilirubinemia. With the administration of second-generation TKIs (2G-TKIs) for a total of 18 months, he achieved a complete response to FL without antilymphoma treatment. This is the first report to suggest that 2G-TKIs may have direct or indirect effects on FL.

Primary malignant lymphoma of the vagina is extremely rare. The most common histologic subtype is diffuse large B-cell lymphoma (DLBCL). We report a case of vaginal DLBCL successfully treated with chemotherapy consisting of rituximab, adryamicin, cyclophosphamide, vincristine sulfate, and prednisolone (R-CHOP), followed by pelvic irradiation. A 44-year-old Japanese woman was admitted complaining of atypical genital bleeding and puruloid vaginal discharge. Gynecological examination showed an ulceration of the vaginal wall and a hard mass the size of a goose egg beneath the left vaginal wall, which had infiltrated to the left pelvic wall. The pathological diagnosis based on a punch biopsy taken from the vaginal tumor was non-Hodgkin's lymphoma. Based on immunohistochemical study, the tumor was subclassified as activated B-cell type DLBCL. The patient was diagnosed with Ann Arbor Stage IEA DLBCL and Stage III vaginal cancer, according to the International Federation of Gynecologists and Obstetricians (FIGO) classification system. She was successfully treated by six courses of R-CHOP, followed by radiation therapy. The patient is well without evidence of disease 13 months following the initial treatment. Little attention has been paid to the use of rituximab in addition to conventional chemotherapy and the importance of clinical and morphological subgrouping of DLBCL arising in the vagina. The present case indicates that the effects of rituximab on the prognosis of vaginal DLBCL must be evaluated, and that clinical use of immunophenotypic subgrouping should be considered for vaginal DLBCL.

Burkitt lymphoma is an aggressive B cell malignancy accounting for 1-2% of all adult lymphomas. Treatment with dose-intensive, multi-agent chemotherapy is effective but associated with considerable toxicity. In this observational study, we compared real-world efficacy, toxicity, and costs of four frequently employed treatment strategies for Burkitt lymphoma: the Lymphome Malins B (LMB), the Berlin-Frankfurt-Münster (BFM), the HOVON, and the CODOX-M/IVAC regimens. We collected data from 147 adult patients treated in eight referral centers. Following central pathology assessment, 105 of these cases were accepted as Burkitt lymphoma, resulting in the following treatment groups: LMB 36 patients, BFM 19 patients, HOVON 29 patients, and CODOX-M/IVAC 21 patients (median age 39 years, range 14-74; mean duration of follow-up 47 months). There was no significant difference between age, sex ratio, disease stage, or percentage HIV-positive patients between the treatment groups. Five-year progression-free survival (69%, p = 0.966) and 5-year overall survival (69%, p = 0.981) were comparable for all treatment groups. Treatment-related toxicity was also comparable with only hepatotoxicity seen more frequently in the CODOX/M-IVAC group (p = 0.004). Costs were determined by the number of rituximab gifts and the number of inpatients days. Overall, CODOX-M/IVAC had the most beneficial profile with regards to costs, treatment duration, and percentage of patients completing planned treatment. We conclude that the four treatment protocols for Burkitt lymphoma yield nearly identical results with regards to efficacy and safety but differ in treatment duration and costs. These differences may help guide future choice of treatment.

Primary lymphomas of the uterine cervix are a rare disease. They are often misdiagnosed because of their rarity and because they can be easily confused with a squamous cell carcinoma of the cervix, as they are usually presented as exophytic mass with vaginal bleeding as their most common symptoms. Nevertheless, considering that both the prognosis and the treatment are completely different between them, differential diagnosis should be taken into account. A case of a 51-year-old woman with a primary diffuse large B-cell lymphoma of the cervix is presented. Diagnosis of this tumor was a challenge for pathologists and clinicians, as four biopsies were needed to achieve a final diagnosis. Patient was successfully treated with combined Rituximab and chemotherapy (R-CHOP) alone. Complete remission, confirmed through biopsy, was reached after six courses of chemotherapy. At 2-years follow up, patient is alive and free of disease. Considering that the prognosis and treatment of primary malignant lymphoma of the cervix are completely different than that of the squamous cell carcinoma, awareness of this disease should be considered in the differential diagnosis.

Nodal marginal zone lymphoma (NMZL) is a B-cell lymphoma that shares morphologic and immunophenotypic features with extranodal and splenic marginal zone lymphomas but lacks extranodal or splenic involvement at presentation. NMZL occurs mostly in adults with no sex predilection, at advanced stage (III or IV), with frequent relapses and a high incidence of tumoral genetic abnormalities including trisomies 3 and 18 and gain of 7q. Pediatric NMZL, however, is a rare but distinct variant of NMZL with characteristic features including male predominance, asymptomatic and localized (stage I) disease, low relapse rates with excellent outcomes, and a lower incidence of essentially similar genetic aberrations compared to adult NMZL. Here we describe a unique case of childhood NMZL with unusual clinicopathologic features for the pediatric variant including generalized lymphadenopathy, high-stage disease with persistence after therapy, unusual immunophenotype (CD5, CD23, and BCL6 positive), and unique chromosomal abnormalities including monosomy 20 and add(10)(p11.2).

To propose an alternative approach for treatment of pulmonary marginal zone lymphoma, using a very small radiation dose (2 × 2 Gy) delivered exclusively to tumor sites. Patients had localized pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma according to the World Health Organization classification. The 6-MV radiation treatments were delivered using tumor-limited fields, except in cases of diffuse bilateral involvement. Two daily fractions of 2 Gy were delivered to tumor-limited fields using a 6-MV linear accelerator. Ten patients with pulmonary MALT lymphoma entered the study. All but 1 had localized tumor masses. The median follow-up was 56 months (range, 2-103 months). Complete remission or an unconfirmed complete remission was obtained in 60% of patients within the first 2 months, and two additional partial responses were converted into a long-term unconfirmed complete remission. All patients are well and alive, no local progression was observed, and the 5-year progression-free survival rate was 87.5% (95% confidence interval 49%-97%). Our results suggest that extremely low radiation doses delivered exclusively to tumor sites might be a treatment option in pulmonary MALT lymphoma. Copyright © 2012 Elsevier Inc.

Advances in the treatment of Hodgkin lymphoma.

Eichenauer, Dennis A; Engert, Andreas

In the past decades, Hodgkin lymphoma (HL) has turned from an incurable disease to one with the most favorable prognosis among adult malignancies. This is due to the introduction of effective multi-agent chemotherapy and the optimization of radiation techniques. At present, 80-90 % of patients achieve long-term remission when receiving appropriate first-line treatment. Even in case of relapse, up to 50 % can be successfully salvaged with high-dose chemotherapy and autologous stem cell transplantation. Thus, current studies do not necessarily aim at increasing treatment efficacy but rather focus on a possible reduction of acute and late toxicity by decreasing treatment intensity if possible. One promising strategy to spare therapy in good-risk patients is early response-adapted treatment stratification according to the result of interim positron emission tomography. The evaluation of novel drugs and the optimization of treatment for elderly HL patients and those with nodular lymphocyte-predominant HL are further aspects that are currently being addressed in ongoing trials. This review will give an overview on more recent clinical trials and discuss possible future strategies for the treatment of HL.

To report a clinical, histopathological and immunohistochemical findings in a case of primary extranodal marginal zone lymphoma of the uvea associated with massive diffuse extraocular episcleral extension and focal infiltration of the optic nerve and meninges, clinically presented as longstanding uveitis masquerade syndrome. Interventional case reports with histopathological correlation. We describe a 80-year-old male patient with a 3-year history of chronic recurrent hypertensive (pan) uveitis associated with ocular pain, unresponsive to topical and systemic anti-inflammatory, immunosuppressive, antibiotic/antiviral and antiglaucomatous therapy. Because the eye was not salvageable with conservative treatment, enucleation of blind and painful eye was performed. Findings from histopathological and immunohistochemistry examination of the enucleated eye showed an extranodal marginal zone lymphoma of the uveal tract with massive epibulbar extension and optic nerve and meningeal penetration. During almost 3 years of clinical course and 6 months after the enucleation, there were no systemic manifestations of lymphoma, and patient has not required subsequent treatment. Primary lymphoproliferative lesions of the uvea, comprising the iris, ciliary body and choroid are very rare, associated with epibulbar extension extremely and with optic nerve and menigeal penetration exceptionally. Despite its rarity, primary lymphoma of the uvea should be included in the differential diagnosis particularly in older patients with longstanding recurrent uveitis.

Radioimmunotherapy for treatment of B-cell lymphomas and other hematologic malignancies.

2007-11-01

Radioimmunotherapy has emerged as one of the most promising treatment options for hematologic malignancies. This review will present the latest information on radioimmunotherapy for treatment of hematologic malignancies in various clinical settings and assess its long-term safety profile. Recent data suggest that radioimmunotherapy with 131I-tositumomab or 90Y-ibritumomab tiuxetan not only induces high response rates but also results in durable remissions in patients with relapsed or refractory indolent non-Hodgkin's lymphomas. Even more notable response rates have been observed when radioimmunotherapy is used as front-line treatment in patients with indolent non-Hodgkin's lymphomas. The use of radioimmunotherapy has been evaluated in the treatment of aggressive lymphomas with promising results, but it remains investigational. Standard doses of radioimmunotherapy given as a conditioning regimen for hematopoietic stem-cell transplant or myeloablative doses of radioimmunotherapy given in conjunction with stem-cell support have yielded encouraging outcomes with durable remissions and a low incidence of treatment-related mortality. The safety and efficacy of radioimmunotherapy has been demonstrated for patients with B-cell lymphomas and other hematologic malignancies in various clinical settings. A number of randomized phase III clinical trials are currently underway to further define radioimmunotherapy's role in the treatment of lymphomas.

The International Extranodal Lymphoma Study Group coordinated a phase II trial to evaluate the activity and safety of everolimus in marginal zone lymphomas (MZLs). Thirty patients with relapsed/refractory MZLs received everolimus for six cycles or until dose-limiting toxicity or progression. Median age was 71 years (range, 51-88 years). Twenty patients had extranodal, six splenic, four nodal MZL. Twenty-four patients had stage III-IV. Median number of prior therapies was two (range 1-5). Seventeen patients had early treatment discontinuation, in most cases due to toxicity. Median number of cycles was 4.5 (range, 1-16). Among the 24 assessable patients, the overall response rate (ORR) was 25% (95% confidence interval: 10-47). Grade 3-4 adverse events were neutropenia and thrombocytopenia (17% of patients, each), infections (17%), mucositis and odontogenic infections (13%) and lung toxicity (3%). The median response duration was 6.8 months (range, 1.4-11.1+). After a median follow-up of 14.5 months, five deaths were reported: four deaths were due to lymphoma, one was due to toxicity. In an intent-to-treat analysis, the projected median progression-free survival was 14 months. The moderate antitumour activity of everolimus in relapsed/refractory MZLs and the observed toxicity limit its therapeutical applicability in these indolent entities. Lower doses of the drug and, perhaps, different strategies including combination with additional agents need to be explored. © 2014 John Wiley & Sons Ltd.

Gray zone lymphoma (GZL) with features between classical Hodgkin lymphoma and diffuse large B-cell lymphoma (DLBCL) is a recently recognized entity reported to present primarily with mediastinal disease (MGZL). We examined detailed clinical features, outcomes, and prognostic factors among 112 GZL patients recently treated across 19 North American centers. Forty-three percent of patients presented with MGZL, whereas 57% had non-MGZL (NMGZL). NMGZL patients were older (50 versus 37 years, P = 0.0001); more often had bone marrow involvement (19% versus 0%, P = 0.001); >1 extranodal site (27% versus 8%, P = 0.014); and advanced stage disease (81% versus 13%, P = 0.0001); but they had less bulk (8% versus 44%, P = 0.0001), compared with MGZL patients. Common frontline treatments were cyclophosphamide-doxorubicin-vincristine-prednisone +/- rituximab (CHOP+/-R) 46%, doxorubicin-bleomycin-vinblastine-dacarbazine +/- rituximab (ABVD+/-R) 30%, and dose-adjusted etoposide-doxorubicin-cyclophosphamide-vincristine-prednisone-rituximab (DA-EPOCH-R) 10%. Overall and complete response rates for all patients were 71% and 59%, respectively; 33% had primary refractory disease. At 31-month median follow-up, 2-year progression-free survival (PFS) and overall survival rates were 40% and 88%, respectively. Interestingly, outcomes in MGZL patients seemed similar compared with that of NMGZL patients. On multivariable analyses, performance status and stage were highly prognostic for survival for all patients. Additionally, patients treated with ABVD+/-R had markedly inferior 2-year PFS (22% versus 52%, P = 0.03) compared with DLBCL-directed therapy (CHOP+/-R and DA-EPOCH-R), which persisted on Cox regression (hazard ratio, 1.88; 95% confidence interval, 1.03-3.83; P = 0.04). Furthermore, rituximab was associated with improved PFS on multivariable analyses (hazard ratio, 0.35; 95% confidence interval, 0.18-0.69; P = 0.002). Collectively, GZL is a heterogeneous

Tanovea® (first named GS-9219, then VDC-1101, generic name: rabacfosadine) is a pro-prodrug or "double" prodrug of PMEG [9-(2-phosphonylmethoxyethyl)guanine], which has been conditionally approved by the US FDA (Food and Drug Administration) for the treatment of lymphoma in dogs. Tanovea has been demonstrated to be effective against non-Hodgkin's lymphoma (NHL) in dogs, as well as canine cutaneous T-cell lymphoma, spontaneous canine multiple myeloma, naïve canine multicentric lymphoma and relapsed canine B-cell lymphoma. As a double prodrug of PMEG, GS-9219 is first converted intracellularly by hydrolysis to cPr-PMEDAP, then deaminated to PMEG, which is then phosphorylated twice to its active metabolite PMEGpp, acting at the level of the cellular DNA polymerases.

mTOR drives tumor growth but also supports T cell function, rendering the applications of mTOR inhibitors complex especially in T cell malignancies. Here we studied the effects of the mTOR inhibitor rapamycin in mouse EL4 T cell lymphoma. Typical pharmacologic rapamycin (1–8 mg/kg) significantly reduced tumor burden via direct suppression of tumor cell proliferation and improved survival in EL4 challenge independent of anti-tumor immunity. Denileukin diftitox (DD)-mediated depletion of regulatory T cells significantly slowed EL4 growth in vivo in a T cell-dependent fashion. However, typical rapamycin inhibited T cell activation and tumor infiltration in vivo and failed to boost DD treatment effects. Low dose rapamycin (LD, 75 μg/kg) increased potentially beneficial CD44hiCD62L+ CD8+ central memory T cells in EL4 challenge, but without clinical benefit. LD rapamycin significantly enhanced DD treatment efficacy, but DD plus LD rapamycin treatment effects were independent of anti-tumor immunity. Instead, rapamycin up-regulated EL4 IL-2 receptor in vitro and in vivo, facilitating direct DD tumor cell killing. LD rapamycin augmented DD efficacy against B16 melanoma and a human B cell lymphoma, but not against human Jurkat T cell lymphoma or ID8agg ovarian cancer cells. Treatment effects correlated with IL-2R expression, but mechanisms in some tumors were not fully defined. Overall, our data define a distinct, biphasic mechanisms of action of mTOR inhibition at doses that are clinically exploitable, including in T cell lymphomas. PMID:27737881

Splenic marginal zone lymphoma (SMZL) is a rare non-Hodgkin lymphoma. We sought to identify prognostic factors and define outcomes in a cohort of 64 patients with SMZL who were treated at two large academic medical centers in North America in the rituximab era. Over a median follow-up of 37.8 (range 6-167.1) months, Kaplan-Meier estimate of median OS was 156.3 months and median PFS was 52.9 months. On univariate analysis, baseline hemoglobin <12 g/dl was associated with inferior OS (p = 0.045). High-risk FLIPI score was associated with inferior PFS when compared with intermediate/low risk (p = 0.05) and marginally significant with regard to OS (p = 0.056). Splenectomy was not predictive of OS or PFS (p = 0.563 and 0.937, respectively). Transformation to diffuse large B-cell lymphoma occurred in four (6.3%) patients during the observation period. OS was comparable to contemporaneous cohorts of patients with extranodal and nodal marginal lymphomas and FLIPI score was highly predictive for inferior PFS and OS when all three cohorts were analyzed together. Outcomes of SMZL, in our series, were excellent, with a median OS of >13 years. Low hemoglobin and high-risk FLIPI were associated with inferior outcomes.

Russo, Andrea L., E-mail: alrusso@partners.org; Chen, Yu-Hui; Martin, Neil E.

Purpose: To investigate clinical and pathologic factors significant in predicting local response and time to further treatment after low-dose involved-field radiation therapy (LD-IFRT) for non-Hodgkin lymphoma (NHL). Methods and Materials: Records of NHL patients treated at a single institution between April 2004 and September 2011 were retrospectively reviewed. Low-dose involved-field radiation therapy was given as 4 Gy in 2 fractions over 2 consecutive days. Treatment response and disease control were determined by radiographic studies and/or physical examination. A generalized estimating equation model was used to assess the effect of tumor and patient characteristics on disease response. A Cox proportional hazardsmore » regression model was used to assess time to further treatment. Results: We treated a total of 187 sites in 127 patients with LD-IFRT. Histologies included 66% follicular, 9% chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma, 10% marginal zone, 6% mantle cell lymphoma (MCL), and 8% other. Median follow-up time was 23.4 months (range, 0.03-92.2 months). The complete response, partial response, and overall response rates were 57%, 25%, and 82%, respectively. A CLL histology was associated with a lower response rate (odds ratio 0.2, 95% confidence interval 0.1-0.5, P=.02). Tumor size, site, age at diagnosis, and prior systemic therapy were not associated with response. The median time to first recurrence was 13.6 months. Those with CLL and age ≤50 years at diagnosis had a shorter time to further treatment for local failures (hazard ratio [HR] 3.63, P=.01 and HR 5.50, P=.02, respectively). Those with CLL and MCL had a shorter time to further treatment for distant failures (HR 11.1 and 16.3, respectively, P<.0001). Conclusions: High local response rates were achieved with LD-IFRT across most histologies. Chronic lymphocytic leukemia and MCL histologies and age ≤50 years at diagnosis had a shorter time to further treatment after LD-IFRT.« less

Radiotherapy for lymphoma of the orbit must be individualized for each patient and clinical setting. Most techniques focus on optimizing the dose to the tumor while sparing the lens. This study describes a technique utilizing magnetic resonance imaging (MRI) and three dimensional (3D) planning in the treatment of orbital lymphoma. A patient presented with an intermediate grade lymphoma of the right orbit. The prescribed tumor dose was 4050 cGy in 18 fractions. Three D planning was carried out and tumor volumes, retina, and lens were subsequently outlined. Dose calculations including dose volume histograms of the target, retina, and lens weremore » then performed. Part of the retina was outside of the treatment volume while 50% of the retina received 90% or more of the prescribed dose. The patient was clinically NED when last seen 2 years following therapy with no treatment-related morbidity. Patients with lymphomas of the orbit can be optimally treated using MRI based 3D treatment planning.« less

Primary cutaneous marginal zone lymphoma (PCMZL) is the second most common B-cell lymphoma of the skin. A recent study has demonstrated a strikingly high prevalence of immunoglobulin (Ig)G4 expression in PCMZL with plasmacytic differentiation. The objective was to investigate the incidence of IgG4 expression in PCMZL, and its correlation with clinical and immunophenotypic features. Multicenter study that utilized immunohistochemistry and in-situ hybridization to evaluate the expression of IgG4, Ig light (κ and λ), and heavy chains (IgM, IgG), and the ratio of T (CD3+) and B (CD20+) cells in biopsy specimens from 30 patients with PCMZL and to correlate these findings with the clinical features. IgG4 expression was observed in 4 out of 30 patients (13%) with PCMZL. Patients with IgG4-positive lymphomas were 57 to 77 years of age (mean, 69) at biopsy. The lesions were solitary in 2 patients with IgG4-positive lymphomas, and were most commonly located on the trunk. Patients with IgG4-negative lymphomas experienced earlier disease onset at an average age of 53 years. The majority of the IgG4-negative cases presented with localized disease, on the trunk and upper extremities. There was no significant difference in the IgG4-positive versus negative cases for the following parameters: Ig κ or λ restriction, B-cell or T-cell predominance, and site of the lesions. IgG4 expression was observed in a minority of PCMZL patients. We did not identify significant clinical or immunophenotypic differences between IgG4 positive and negative cases.

mTOR drives tumor growth but also supports T-cell function, rendering the applications of mTOR inhibitors complex especially in T-cell malignancies. Here, we studied the effects of the mTOR inhibitor rapamycin in mouse EL4 T-cell lymphoma. Typical pharmacologic rapamycin (1-8 mg/kg) significantly reduced tumor burden via direct suppression of tumor cell proliferation and improved survival in EL4 challenge independent of antitumor immunity. Denileukin diftitox (DD)-mediated depletion of regulatory T cells significantly slowed EL4 growth in vivo in a T-cell-dependent fashion. However, typical rapamycin inhibited T-cell activation and tumor infiltration in vivo and failed to boost DD treatment effects. Low-dose (LD) rapamycin (75 μg/kg) increased potentially beneficial CD44hiCD62L + CD8 + central memory T cells in EL4 challenge, but without clinical benefit. LD rapamycin significantly enhanced DD treatment efficacy, but DD plus LD rapamycin treatment effects were independent of antitumor immunity. Instead, rapamycin upregulated EL4 IL2 receptor in vitro and in vivo, facilitating direct DD tumor cell killing. LD rapamycin augmented DD efficacy against B16 melanoma and a human B-cell lymphoma, but not against human Jurkat T-cell lymphoma or ID8agg ovarian cancer cells. Treatment effects correlated with IL2R expression, but mechanisms in some tumors were not fully defined. Overall, our data define a distinct, biphasic mechanisms of action of mTOR inhibition at doses that are clinically exploitable, including in T-cell lymphomas.

In splenic marginal zone lymphoma (SMZL), specific and functional Toll-like Receptor (TLR) patterns have been recently described, suggesting their involvement in tumoral proliferation. Splenic diffuse red pulp lymphoma with villous lymphocytes (SDRPL) is close to but distinct from SMZL, justifying here the comparison of TLR patterns and functionality in both entities. Distinct TLR profiles were observed in both lymphoma subtypes. SDRPL B cells showed higher expression of TLR7 and to a lesser degree TLR9, in comparison to SMZL B cells. In both entities, TLR7 and TLR9 pathways appeared functional, as shown by IL-6 production upon TLR7 and TLR9 agonists stimulations. Interestingly, circulating SDRPL, but not SMZL B cells, constitutively expressed CD86. In addition, stimulation with both TLR7 and TLR9 agonists significantly increased CD80 expression in circulating SDRPL but not SMZL B cells. Finally, TLR7 and TLR9 stimulations had no impact on proliferation and apoptosis of SMZL or SDRPL B cells. In conclusion, SMZL and SDRPL may derive from different splenic memory B cells with specific immunological features that can be used as diagnosis markers in the peripheral blood.

Monoclonal antibodies in the treatment of non-Hodgkin's lymphoma.

Fanale, Michelle A; Younes, Anas

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.

The objectives of this study were (1) to determine the clinical presentation and natural history associated with two newly recognized pathologic entities termed mantle cell lymphoma (MCL) and marginal zone lymphoma (MZL), including the mucosa-associated lymphoid tissue (MALT) and monocytoid B-cell subcategories, and (2) to determine whether these entities differ clinically from the other relatively indolent non-Hodgkin's lymphomas with which they have been previously classified. We reviewed the conventional pathology and clinical course of 376 patients who had no prior therapy; had stage III/IV disease; were classified as Working Formulation categories A, B, C, D, or E; and received cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) on Southwest Oncology Group (SWOG) studies no. 7204, 7426, or 7713. All slides were reviewed by the three pathologists who reached a consensus diagnosis. Age, sex, performance status, bone marrow and/or gastrointestinal involvement, failure-free survival, and overall survival were compared among all the categories. We found that (1) MCL and MZL each represent approximately 10% of stage III or IV patients previously classified as Working Formulation categories A through E and treated with CHOP on SWOG clinical trials; (2) the failure-free survival and overall survival of patients with MZL is the same as that of patients with Working Formulation categories A through E, but the failure-free survival and overall survival of the monocytoid B-cell patients were higher than that of the MALT lymphoma patients (P = .009 and .007, respectively); and (3) the failure-free survival and overall survival of patients with MCL is significantly worse than that of patients with Working Formulation categories A through E (P = .0002 and .0001, respectively). In conclusion, patients with advanced stage MALT lymphomas may have a more aggressive course than previously recognized. Patients with MCL do not have an indolent lymphoma and are candidates

Recent trends and current knowledge on the diagnosis and treatment strategy for gastric mucosa-associated lymphoid tissue (MALT) lymphoma are reviewed. Helicobacter pylori infection plays the causative role in the pathogenesis, and H pylori eradication is the first-line treatment of this disease, which leads to complete remission in 60% to 90% of cases. A Japanese multicenter study confirmed that the long-term outcome of gastric MALT lymphoma after H pylori eradication is excellent. Treatment strategies for patients not responding to H pylori eradication including "watch and wait" strategy, radiotherapy, chemotherapy, rituximab immunotherapy, and combination of these should be tailored in consideration of the disease extent in each patient.

During the past decade, mantle-cell lymphoma has been established as a new disease entity. The normal counterparts of the cells forming this malignant lymphoma are found in the mantle zone of the lymph node, a thin layer surrounding the germinal follicles. These cells have small to medium-sized nuclei, are commonly indented or cleaved, and stain positively with CD5, CD20, cyclin D1, and FMC7 antibodies. Because of its morphological appearance and a resemblance to other low-grade lymphomas, many of which grow slowly, this lymphoma was initially thought to be an indolent tumour, but its natural course was not thoroughly investigated until the 1990s, when the BCL1 oncogene was identified as a marker for this disease. Mantle-cell lymphoma is a discrete entity, unrelated to small lymphocytic or small-cleaved-cell lymphomas.

To describe a case of extranodal marginal zone B-cell lymphoma (EMZL) "mucosa associated lymphoid tissue (MALT)" of the orbit that presented with stage IV disease in a patient with sarcoidosis. Clinicopathologic case report. Biopsies of the lesion were performed in the operating room and the samples were submitted for pathology processing. Pathology analysis identified the lesion as an extranodal marginal zone B-cell lymphoma "mucosa associated lymphoid tissue (MALT)" via flow cytometry, histopathology, cytogenetics, and immunohistochemical staining and fluorescent in situ hybridization (FISH). The institutional review board of Howard University Hospital waived the need for IRB approval for this intraoperative finding. A 70-year-old Black woman with biopsy-proven sarcoidosis presented complaining of foreign body sensation, redness, swelling of her left upper eyelid and tearing. The patient was found to have an orbital lymphoproliferative malignancy. It is still unclear if the presence of immunosuppression or an autoimmune disease increases the risk of lymphoproliferative malignancies {6}. Malignancy should always be suspected and investigated.

Primary cutaneous B-cell lymphomas (CBCL) represent approximately 20% to 25% of all primary cutaneous lymphomas. With the advent of the World Health Organization-European Organization for Research and Treatment of Cancer (EORTC) Consensus Classification for Cutaneous Lymphomas in 2005, uniform terminology and classification for this rare group of neoplasms were introduced. However, staging procedures and treatment strategies still vary between different cutaneous lymphoma centers, which may be because consensus recommendations for the management of CBCL have never been published. Based on an extensive literature search and discussions within the EORTC Cutaneous Lymphoma Group and the International Society for Cutaneous Lymphomas, the present report aims to provide uniform recommendations for the management of the 3 main groups of CBCL. Because no systematic reviews or (randomized) controlled trials were available, these recommendations are mainly based on retrospective studies and small cohort studies. Despite these limitations, there was consensus among the members of the multidisciplinary expert panel that these recommendations reflect the state-of-the-art management as currently practiced in major cutaneous lymphoma centers. They may therefore contribute to uniform staging and treatment and form the basis for future clinical trials in patients with a CBCL.

Constitutive B-cell receptor signaling leads to overexpression of the antiapoptotic BCL-2 protein and is implicated in the pathogenesis of many types of B-cell non-Hodgkin lymphoma (B-NHL). The BCL-2 small-molecule inhibitor venetoclax shows promising clinical response rates in several lymphomas, but is not curative as monotherapy. Radiotherapy is a rational candidate for combining with BCL-2 inhibition, as DNA damage caused by radiotherapy increases the activity of pro-apoptotic BCL-2 pathway proteins, and lymphomas are exquisitely sensitive to radiation. We tested B-NHL responses to venetoclax combined with either external beam radiotherapy or radioimmunotherapy (RIT), which joins the selectivity of antibody targeting with the effectiveness of irradiation. We first tested cytotoxicity of cesium-137 irradiation plus venetoclax in 14 B-NHL cell lines representing five lymphoma subtypes. Combination treatment synergistically increased cell death in 10 of 14 lines. Lack of synergy was predicted by resistance to single-agent venetoclax and high BCL-XL expression. We then assessed the efficacy of external beam radiotherapy plus venetoclax in murine xenograft models of mantle cell (MCL), germinal-center diffuse large B-cell (GCB-DLBCL), and activated B-cell (ABC-DLBCL) lymphomas. In each model, external beam radiotherapy plus venetoclax synergistically increased mouse survival time, curing up to 10%. We finally combined venetoclax treatment of MCL and ABC-DLBCL xenografts with a pretargeted RIT (PRIT) system directed against the CD20 antigen. Optimal dosing of PRIT plus venetoclax cured 100% of mice with no detectable toxicity. Venetoclax combined with radiotherapy may be a promising treatment for a wide range of lymphomas Cancer Res; 77(14); 3885-93. ©2017 AACR . ©2017 American Association for Cancer Research.

Chemotherapy for multicentric canine lymphoma has favorable results. The gastrointestinal (GI) tract is the most common extranodal site of canine lymphoma, but there have been no prospective studies to determine outcome when dogs with GI lymphoma are treated with chemotherapy. Treatment with a multiagent chemotherapy protocol is associated with a poor outcome in dogs with GI lymphoma. Eighteen dogs with histologically confirmed GI lymphoma. Prospective clinical trial in which dogs with GI lymphoma were treated with a 20-week combination chemotherapy protocol consisting of induction and consolidation phases. Thirteen dogs had primary GI lymphoma and 5 had multicentric lymphoma with GI involvement. The majority of the lymphomas (63%) were of T-cell origin. Overall remission rate was 56%; 9 dogs achieved a complete remission for a median of 86 days (range, 22-420 days) and 1 dog achieved a partial remission for 26 days. Overall median survival time was 77 days (range, 6-700 days). Dogs that failed to achieve a remission (10 versus 117 days; P= .002) or had diarrhea at initial presentation (70 versus 700 days; P < .001) had shorter survival times. The response and survival of dogs with GI lymphoma treated with multiagent chemotherapy is poor but long-term survival is possible.

We have recently reported a series of 15 non-villous splenic marginal zone lymphoma patients, six of whom showed p53 mutations (40%). This molecular alteration did not correlate with any particular clinico-pathologic feature at diagnosis. After a median follow-up of 56 months, four cases evolved into aggressive fatal non-Hodgkin's lymphoma (NHL) and two had refractory progressive disease; interestingly, p53 mutations were demonstrated in five of these patients at diagnosis. As the patients with wild-type p53 presented responsive or indolent disease, this genetic alteration may be an early marker of aggressive transformation or refractoriness. p53 evaluation at diagnosis could be advisable in this particular subset of NHL.

Follicular lymphoma (FL) is the most common indolent lymphoma and it most frequently presents in an advanced-stage. Therapeutic considerations for advanced-stage are different from those of localized-stage FL, in which radiotherapy (RT) is generally recommended. However, the available evidence suffers from shortcomings that are relatively specific to this clinical entity due to its rarity and long survival with all available treatment modalities, including that most of the existing evidence originated at a time when diagnostic classifications, staging procedures and radiotherapeutic standards were different from those available today and when anti-CD20 monoclonal antibodies were not available. Available treatment modalities include observation, systemic therapy only, RT only and RT in combination with systemic therapy. We review the evidence available with each of them and the data from present day clinical practice studies as well as briefly discuss what diagnostic and therapeutic developments may take place in the next few years.

Choroidal metastasis is rare in cancer patients and it may cause visual disturbances that reduce their quality of life. In non-small cell lung cancer (NSCLC), targeted therapy against actionable driver mutations has gradually replaced radiotherapy as the treatment of choice for choroidal metastasis. Recently, there have been several case reports of choroidal metastasis in patients with anaplastic lymphoma kinase (ALK)-rearranged NSCLC. We herein report the case of a 40-year-old Japanese woman diagnosed with choroidal metastasis of an ALK-rearranged NSCLC who received alectinib as the first-line chemotherapy. Alectinib may be the best treatment for choroidal metastasis in patients harboring an ALK translocation because of its favorable side effect profile involving visual disturbances. PMID:28794371

Background Brentuximab vedotin (BV) is an antibody-drug conjucate (ADC) comprising a CD30-directed antibody, conjugated to the microtubule-disrupting agent MMAE via a protease cleavable linker. BV is FDA approved for use in relapsed classical Hodgkin lymphoma (HL) and relapsed systemic anaplastic large cell lymphoma (sALCL). There are multiple publications for its utility in other malignancies such as diffuse large B-cell lymphoma (DLBCL), mycosis fungoides (MF), Sézary syndrome (SS), T-cell lymphomas (TCL), primary mediastinal lymphoma (PMBL), and post-transplant lymphoproliferative disorders (PTLD). We believe that BV could potentially provide a strong additional treatment option for patients suffering from NHL. Objective Perform a systematic review on the use of BV in non-Hodgkin lymphoma (NHL) and other CD30+ malignancies in humans. Data sources We searched various databases including PubMed (1946–2015), EMBASE (1947–2015), and Cochrane Central Register of Controlled Trials (1898–2015). Eligibility criteria Inclusion criteria specified all studies and case reports of NHLs in which BV therapy was administered. Included studies A total of 28 articles met these criteria and are summarized in this manuscript. Conclusion Our findings indicate that BV induces a variety of responses, largely positive in nature and variable between NHL subtypes. With additional, properly powered prospective studies, BV may prove to be a strong candidate in the treatment of various CD30+ malignancies. PMID:28010897

Purpose Mounting evidence supports the clinical significance of gene mutations and immunogenetic features in common mature B-cell malignancies. Experimental Design We undertook a detailed characterization of the genetic background of splenic marginal zone lymphoma (SMZL), using targeted re-sequencing and explored potential clinical implications in a multinational cohort of 175 SMZL patients. Results We identified recurrent mutations in TP53 (16%), KLF2 (12%), NOTCH2 (10%), TNFAIP3 (7%), MLL2 (11%), MYD88 (7%) and ARID1A (6%), all genes known to be targeted by somatic mutation in SMZL. KLF2 mutations were early, clonal events, enriched in patients with del(7q) and IGHV1-2*04 B-cell receptor immunoglobulins, and were associated with a short median time-to-first-treatment (0.12 vs. 1.11 yrs; P=0.01). In multivariate analysis mutations in NOTCH2 (HR 2.12, 95%CI 1.02-4.4, P=0.044) and 100% germline IGHV gene identity (HR 2.19, 95%CI 1.05-4.55, P=0.036) were independent markers of short time-to-first-treatment, while TP53 mutations were an independent marker of short overall survival (HR 2.36, 95% CI 1.08-5.2, P=0.03). Conclusion We identify key associations between gene mutations and clinical outcome, demonstrating for the first time that NOTCH2 and TP53 gene mutations are independent markers of reduced treatment-free and overall survival, respectively.

A 53-year-old female developed epigastric discomfort and back pain in 2007. Diagnostic imaging studies demonstrated a soft tissue tumor with heterogeneous enhancement in the anterior mediastinum and multiple nodules in the right lung. She underwent expanded thymectomy with subtotal resection of the right lung. The pathological diagnosis was primary thymic mucosa-associated lymphoid tissue (MALT) lymphoma. The patient complained of ocular discomfort, oral dryness and continuous nasal bleeding in 2007. Detailed examination led to a diagnosis of Sjögren syndrome and acquired von Willebrand syndrome. Rituximab treatment for residual disease achieved not only a reduction of the lung MALT lymphoma but also clinical and hematological remission of both syndromes. This is, to our knowledge, the first reported case of primary thymic MALT lymphoma accompanied by Sjögren and acquired von Willebrand syndromes.

Relationships between lymphomas linked to hepatitis C virus infection and their microenvironment

PubMed Central

Carbone, Antonino; Gloghini, Annunziata

2013-01-01

The relationships between lymphomas and their microenvironment appear to follow 3 major patterns: (1) an independent pattern; (2) a dependent pattern on deregulated interactions; and (3) a dependent pattern on regulated coexistence. Typical examples of the third pattern are hepatitis C virus (HCV)-associated marginal zone lymphomas (MZLs) and mucosa-associated lymphoid tissue lymphomas. In these lymphomas, a regulated coexistence of the malignant cells and the microenvironmental factors usually occurs. At least initially, however, tumor development and cell growth largely depend on external signals from the microenvironment, such as viral antigens, cytokines, and cell-cell interactions. The association between HCV infection and B-cell lymphomas is not completely defined, although this association has been demonstrated by epidemiological studies. MZL and diffuse large B-cell lymphoma are the histotypes most frequently associated with HCV infection. Many mechanisms have been proposed for explaining HCV-induced lymphomagenesis; antigenic stimulation by HCV seems to be fundamental in establishing B-cell expansion as observed in mixed cryoglobulinemia and in B-cell lymphomas. Recently, antiviral treatment has been proved to be effective in the treatment of HCV-associated indolent lymphomas. Importantly, clinically responses were linked to the eradication of the HCV-RNA, providing a strong argument in favor of a causative link between HCV and lymphoproliferation. PMID:24307781

There have been sporadic reports about synchronous as well as metachronous gastric adenocarcinoma and primary gastric lymphoma. Many reports have dealt with metachronous gastric adenocarcinoma in mucosa-associated lymphoid tissue lymphoma of stomach. But to our knowledge, there have been no reports that document the increased incidence of metachronous gastric adenocarcinoma in patients with gastric diffuse large B-cell lymphoma. This retrospective study was conducted to estimate the incidence of metachronous gastric adenocarcinoma after primary gastric lymphoma treatment, especially in diffuse large B-cell lymphoma. The retrospective cohort study of 139 primary gastric lymphoma patients treated with radiotherapy at our hospital. Mean observation period was 61.5 months (range: 3.7-124.6 months). Patients profile, characteristics of primary gastric lymphoma and metachronous gastric adenocarcinoma were retrieved from medical records. The risk of metachronous gastric adenocarcinoma was compared with the risk of gastric adenocarcinoma in Japanese population. There were 10 (7.2%) metachronous gastric adenocarcinoma patients after treatment of primary gastric lymphomas. It was quite high risk compared with the risk of gastric carcinoma in Japanese population of 54.7/100,000. Seven patients of 10 were diffuse large B-cell lymphoma and other 3 patients were mixed type of diffuse large B-cell lymphoma and mucosa associated lymphoid tissue lymphoma. Four patients of 10 metachronous gastric adenocarcinomas were signet-ring cell carcinoma and two patients died of gastric adenocarcinoma. Metachronous gastric adenocarcinoma may have a more malignant potential than sporadic gastric adenocarcinoma. Old age, Helicobacter pylori infection and gastric mucosal change of chronic gastritis and intestinal metaplasia were possible risk factors for metachronous gastric adenocarcinoma. There was an increased risk of gastric adenocarcinoma after treatment of primary gastric lymphoma

Lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) of the stomach usually occurs as a consequence of Helicobacter pylori (H. pylori) infection. The aim of this study was to investigate the long-term effect of treatment of low-grade gastric MALT lymphoma with the H. pylori eradication method. In the period 2002-2012 in 20 patients with dyspepsia, mean age 55.1 years, the endoscopic and histologic diagnosis of gastric MALT lymphoma in the early stages were made. Histological preparations of endoscopic biopsy specimens were stained with hematoxyllineosin (HE), histochemical and immunohistochemical methods. Endoscopic findings of gastritis were documented in 25% of the patients, and 75% of the patients had hypertrophic folds, severe mucosal hyperemia, fragility, nodularity, exulcerations and rigidity. Histopathologically, pathognomonic diagnostic criterion were infiltration and destruction of glandular epithelium with neoplastic lymphoid cells, the so-called lymphoepithelial lesions. In all 20 patients H. pylori was verified by rapid urease test and Giemsa stain. After the triple eradication therapy complete remission of MALT lymphoma was achieved in 85% of the patients, with no recurrence of lymphoma and H. pyloi infection in the average follow-up period of 48 months. In 3 (15%) of the patients, there was no remission of MALT lymphoma 12 months after the eradication therapy. Of these 3 patients 2 had progression of MALT lymphoma to diffuse large-cell lymphoma. Durable complete remission of low-grade gastric MALT lymphoma is achieved in a high percentage after eradication of H. pylori infection, thus preventing the formation of diffuse large-cell lymphoma and gastric adenocarcinoma.

Assessment of hematologic improvement, survival and peri-operative morbidity after first-line splenectomy for splenic marginal zone lymphoma (SMZL). Forty-three patients undergoing open splenectomy were prospectively analyzed. Perioperative clinical course, overall and progression-free survival (OS-PFS) were evaluated. Risk factors analyzed were gender, age, ASA-grade, ECOG performance status, presence of B-symptoms, body mass index, steroidal treatment, serum albumin concentration, IIL-score, operative time, spleen size and weight. The median follow-up was 31 months (IQR 15-76; range 24-154). Anemia and thrombocytopenia resolved in 80% of patients at 6 months; in 60% at 2 years. The 5-year and 10-year PFS were 35% and 13% respectively, with a median of 35 months (shorter in patients with ECOG performance status ≥2 and B-symptoms). Nineteen cases (44.2%) had a progression of disease within 2 years. Of these, 14 (32.6%) received adjuvant chemotherapy (mainly R-FC or R-CVP). Progression was attributed to high-grade B lymphoma in 7 (16.3%) patients. The median time between diagnosis and progression to aggressive lymphoma was 25.5 months (range 18.8-81.8). The median time to next treatment was 83.5 months (95% CI 49-118). The 5-year and 10-year OS were 75% and 53% respectively. Mortality was due to disease progression and histological transformation in high-grade B lymphoma in 50% of cases, myelodisplastic syndrome in 15%, recurrence of hemolytic anemia in 15%, Hodgkin lymphoma in 7% and to infections (mainly pulmonary) in the remaining 13% of cases. Post-operative morbidity was 2.3% (1 patient with grade-3 complication). Overall grade ≥2 complication rate was 32.5% (mainly hemorrhagic and pulmonary complications). Spleen weight was the only independent risk factor for morbidity. Mortality was nil. Splenectomy is safe and effective as regards cytopenia resolution and OS, although disease progression is frequently observed at follow-up. Such results are strictly

Our patient was an 86-year-old man who had worked as a lathe operator for 40 years. He had no history of tuberculosis, pyothorax, or autoimmune disease. He had not been exposed to asbestos. He was asymptomatic, but an imaging study showed gradually increasing pleural plaques. A biopsy specimen of a pleural lesion showed sclerosis of the pleura and diffuse infiltration of small- to medium-sized B lymphocytes. Polymerase chain reaction-based analysis detected monoclonal rearrangement of immunoglobulin heavy-chain genes. Histologic diagnosis was extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue type (MALT lymphoma). The lymphoma was negative for Epstein-Barr virus. We report a rare case of a metal worker with MALT lymphoma arising in the pleura with pleural fibrous plaques. It is speculated that MALT lymphoma might develop in the background of pneumoconiosis. Inflammatory and/or immunologic reactions to metal particles might contribute to the oncogenesis of this tumor. Copyright © 2012 Elsevier Inc. All rights reserved.

Alectinib is an oral drug developed for the treatment of patients with fusion gene encoding echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase ( EML4-ALK )-rearranged non-small cell lung cancer (NSCLC). Here, we present the case of a patient treated with alectinib who developed a hypersensitivity reaction with successful rechallenge treatment. A 39-year-old woman who was a passive smoker was referred to Osaka City University Hospital for the evaluation of a skin event caused by treatment for NSCLC with the fusion gene EML4-ALK . The skin reaction was observed on the anterior chest, upper arms, and ear auricles on day 11 of treatment with oral alectinib. The skin event presented as widely distributed erythematous macules that were confluent, indicating a severe and life-threatening form. The skin lesions started to resolve after the initiation of treatment with 40 mg prednisolone. After regrowth of the tumor, she received a rechallenge program for alectinib for 2 weeks; thereafter, alectinib treatment was successfully reinitiated. To the best of our knowledge, we present the first case in which alectinib, which binds to the adenosine triphosphate site of EML4-ALK , induced erythema multiforme. Moreover, successful readministration of alectinib through our rechallenge program has not been reported so far.

Treatment decisions in a man with Hodgkin lymphoma and Guillian-Barré syndrome: a case report.

Hughes, Caren L; Yorio, Jeffrey T; Kovitz, Craig; Oki, Yasuhiro

2014-12-21

Guillain-Barre syndrome, or acute inflammatory demyelinating polyneuropathy, has been described in the presence of malignancies such as lymphoma. Guillain-Barre syndrome/acute inflammatory demyelinating polyneuropathy causes paresthesias and weakness, which can make the treatment of lymphoma with chemotherapy challenging. Given the rarity of this co-presentation it is not known if the effects of Guillain-Barre syndrome should be considered when selecting a treatment regimen for Hodgkin lymphoma. To the best of our knowledge, the impact of these treatment modifications has not been previously reported. We report the case of a 37-year-old Caucasian man with a diagnosis of stage IIB classical Hodgkin lymphoma with concomitant Guillain-Barre syndrome. Our patient originally presented with an enlarged cervical lymph node and quickly developed distal paresthesia and progressive weakness of all four extremities. He was diagnosed with Hodgkin's lymphoma and initiated on treatment with doxorubicin, bleomycin, vinblastine, and dacarbazine. Doses of bleomycin and vinblastine were held or dose-reduced throughout his initial treatment course due to underlying neuropathy and dyspnea. He continued to have persistent disease after five cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine and went on to receive salvage treatments including more chemotherapy, radiation, autologous stem cell transplant and is currently preparing for an allogeneic stem cell transplant. Paraneoplastic syndromes such as Guillain-Barre syndrome/acute inflammatory demyelinating polyneuropathy can make the treatment of patients with Hodgkin lymphoma more challenging and can interfere with delivering full-dose chemotherapy. Further case series are needed to evaluate the effect that paraneoplastic syndromes, or adjustments made in therapy due to these syndromes, negatively affect the prognosis of patients with Hodgkin lymphoma.

A 14 yr-old male, vasectomized African lion (Panthera leo) exhibited mild weight loss despite adequate appetite. Splenomegaly was diagnosed on physical examination. On the basis of hematology and clinical pathology, malignant lymphoma with chronic lymphocytic leukemia was diagnosed. Abdominal exploratory surgery and splenectomy were performed. Histologic examination and immunohistochemistry confirmed a small cell peripheral T-cell lymphoma. Initial treatments consisted of doxorubicin and prednisone, with later addition of lomustine. The lion remained in clinical remission at 2 mo, 6 mo, and 12 mo postchemotherapy physical examinations. The lion survived 504 days from initial diagnosis. At necropsy, the only lesions consistent with lymphoma were localized epitheliotrophic infiltrates of small neoplastic T lymphocytes within the nasopharyngeal epithelium and the underlying submucosa observed on microscopic examination.

Primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is a low-grade B cell lymphoma that is a type of non-Hodgkin lymphoma and a type of primary pulmonary malignant lymphoma. MALT lymphomas affecting the lung show various findings on chest computed tomography, which range from typical nodules or areas of consolidation to findings that are extremely rare in pulmonary MALT lymphomas, such as pure ground-glass opacities throughout the lung. A 35-year-old woman was found to have a few shadows with ground glass opacities on chest computed tomography (CT) in 2012. A shadow in right S10 that was initially very small increased in size over time, and was 14 × 8 mm in 2015. Other shadows also appeared. Because lung adenocarcinoma was suspected, the patient underwent video-assisted thoracoscopic surgery with a right wedge resection of the lower lobe that included the largest nodule in S10 and other nodules. Histopathological examination of the right S10 and other lesions revealed small- or medium-sized lymphocyte-like cells that were located in the alveolar interseptal spaces. The alveolar walls remained intact. Immunohistochemical staining showed that tumor cells were positive for CD20, CD79a, and BCL2 expression. The lesions were diagnosed as extranodal marginal zone B-cell lymphoma of MALT. We think that the ground glass opacities on CT were accounted for by MALT lesions that contained intact alveolar air spaces. The patient has remained well during 12 months of follow up after surgery. Although she did not receive chemotherapy because the MALT lymphoma lesions have been stable without progression, the patient is kept under close observation because of potential progression of the disease.

Pediatric nodal marginal zone lymphoma may develop in the adult population.

Pediatric nodal marginal zone lymphoma (NMZL) is described as a separate variant of NMZL in the most recent WHO classification of tumors of hematologic and lymphoid tissues. It has distinctive morphology and clinical presentation and stands out as an indolent disease with remarkably better overall prognosis compared to classic NMZL. Here we report two adult patients with NMZL with clinical and morphologic features consistent with pediatric NMZL (pNMZL) and review available literature describing the clinical and histologic presentation of pNMZL. Two men, ages 44 and 18 years, each presented with localized cervical lymphadenopathy, both demonstrated florid proliferation of the marginal zone and disruption of reactive germinal centers, progressive transformation of germinal centers-like morphologic features typical for pNMZL and clonal disease with immunophenotype consistent with NMZL. This is the first report of pNMZL in a middle-aged person. Distinct histologic features and characteristic benign clinical course will help to distinguish this rare variant from other NMZL in the adults. Clinically, recognition is important to understand the true incidence of this rare form in the adult population and to avoid unnecessary overtreatment of this indolent form.

Evaluating sphingosine and its analogues as potential alternatives for aggressive lymphoma treatment.

PubMed

Ceramide (Cer) and sphingosine (Sph) interfere with critical cellular functions relevant for cancer progression and cell survival. While Cer has already been investigated as a potential drug target for lymphoma treatment, information about the potency of sphingosine is scarce. The aim of this study therefore was to evaluate Sph and its synthetic stereoisomer L-threo-sphingosine (Lt-Sph) as potential treatment options for aggressive lymphomas. Diffuse large B cell lymphoma (DLBCL) cell lines were incubated with Sph and Lt-Sph and consequently analysed by flow cytometry (FACS), enzyme-linked immunosorbent assay (ELISA), liquid chromatography coupled to triple-quadrupole mass spectrometry (LC/MS/MS), electron microscopy, and Western blot. Sph induced cell death and blocked cell growth independently of S1P receptors in different DLBCL cell lines. Three different modes of Sph-mediated cell death were observed: Apoptosis, autophagy, and protein kinase C (PKC) inhibition. Generation of pro-apoptotic Cer accounted only for a minor portion of the apoptotic rate. Sph and its analogues could evolve as alternative treatment options for aggressive lymphomas via PKC inhibition, apoptosis, and autophagy. These physiological responses induced by different intracellular signalling cascades (phosphorylation of JNK, PARP cleavage, LC3-II accumulation) identify Sph and analogues as potent cell death inducing agents. © 2014 S.

Reported herein is a case of EBV-associated gastric carcinoma with primary gastric extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma). A 69-year-old Japanese man was found to have an ulcer lesion in his stomach on endoscopy, and a biopsy indicated malignancy. He underwent gastrectomy. Microscopically the tumor had features typical of lymphoepithelioma-like carcinoma. The neoplastic epithelial cells proliferated in a trabecular fashion. On in situ hybridization for EBV-encoded RNA, positive signals were observed in most neoplastic epithelial cells. Numerous lymphocytes surrounded the neoplastic epithelial cells. In the stroma, numerous lymphocytes with mild atypia were positive for CD20 and CD79a. In addition, monoclonal proliferation of B cells was confirmed on polymerase chain reaction for IgH. These findings supported MALT lymphoma. The coexistence of EBV-associated gastric carcinoma and MALT lymphoma is extremely rare.

OBJECTIVE: Diffuse large B-cell lymphoma is the most common type of non-Hodgkin lymphoma, accounting for nearly 50% of the cases in the Hematology Department of the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo and Instituto do Câncer do Estado de São Paulo. The treatment outcome is influenced by age, abnormal lactate dehydrogenase levels, extranodal infiltration, the disease stage and the patient's performance status. In this study, we sought to report the time-to-treatment of diffuse large B-cell lymphoma in São Paulo's public health system network and its impact on patient outcomes. METHODS: We prospectively followed a cohort of 42 consecutive patients with de novo diffuse large B-cell lymphoma between 2008 and 2012. RESULTS: Our patients had more advanced disease than that reported in the literature (61.9% vs. 46%). In São Paulo's public health system network, it took an average of 7.4 months for a diagnosis to be made and an additional 1.4 months to obtain an appointment with a specialist. Once at our Hematology Department, it took less than 20 days for staging, confirmation of the diagnosis and treatment initiation. An interval from signs or symptoms to treatment of more than 6 months was associated with inferior progression-free survival in 3 years (p = 0.049). CONCLUSION: A delay in the diagnosis of diffuse large B-cell lymphoma is a public health problem and may be associated with worse progression-free survival. PMID:24838904

The B-cell receptor (BCR) is essential for normal B-cell development and maturation. In an increasing number of B-cell malignancies, BCR signaling is implicated as a pivotal pathway in tumorigenesis. Mechanisms of BCR activation are quite diverse and range from chronic antigenic drive by microbial or viral antigens to autostimulation of B-cells by self-antigens to activating mutations in intracellular components of the BCR pathway. Hepatitis C virus infection can lead to the development of splenic marginal zone lymphoma, while Helicobacter pylori infection is associated with the development of mucosa-associated lymphoid tissue lymphomas. In some of these cases, successful treatment of the infection removes the inciting antigen and results in resolution of the lymphoma. Chronic lymphocytic leukemia has been recognized for decades as a malignancy of auto-reactive B-cells and its clinical course is in part determined by the differential response of the malignant cells to BCR activation. In a number of B-cell malignancies, activating mutations in signal transduction components of the BCR pathway have been identified; prominent examples are activated B-cell-like (ABC) diffuse large B-cell lymphomas (DLBCL) that carry mutations in CD79B and CARD11 and display chronic active BCR signaling resulting in constitutive activation of the NF-κB pathway. Despite considerable heterogeneity in biology and clinical course, many mature B-cell malignancies are highly sensitive to kinase inhibitors that disrupt BCR signaling. Thus, targeted therapy through inhibition of BCR signaling is emerging as a new treatment paradigm for many B-cell malignancies. Here, we review the role of the BCR in the pathogenesis of B-cell malignancies and summarize clinical results of the emerging class of kinase inhibitors that target this pathway. Copyright © 2013.

Lymphoma is the commonest pediatric cancer in sub-Saharan Africa (SSA). Frequent treatment abandonment contributes to suboptimal outcomes. We examined risk factors and reasons for treatment abandonment for this population in Malawi. We conducted a mixed methods study among children < 18 years old with newly diagnosed lymphoma, prospectively enrolled during 2013-2016. All children received standardized diagnosis and treatment, and were followed for up to 2 years. Treatment abandonment was defined as failure to attend prescribed chemotherapy within 4 weeks, or post-treatment visit within 3 months. Child, guardian, and household characteristics associated with treatment abandonment were assessed. Semi-structured interviews were conducted with primary caregivers of children experiencing treatment abandonment. Of 121 children with newly diagnosed lymphoma, 72 (60%) had complete information regarding child, guardian, and household characteristics. Of these, 56 (78%) had Burkitt's and 16 (22%) Hodgkin's lymphoma. Forty-nine (68%) were male, median age was 10.6 years (interquartile range [IQR] 7.9-13.0), and 26 (36%) experienced treatment abandonment. Lack of guardian education and travel time ≥ 4 h to clinic were independently associated with treatment abandonment, with adjusted hazard ratio (aHR) 3.8 [95% confidence interval (CI) 1.5-8.9, p = 0.005] and aHR 2.9 (95% CI 1.2-6.9, p = 0.019), respectively. Commonest reasons for treatment abandonment endorsed by 15 guardians were community influence, suboptimal clinic environment, logistical challenges, transport costs, treatment toxicities, loss of hope, alternative healers, and beliefs about cure. These findings highlight families at risk for treatment abandonment, underlying reasons, and opportunities to improve retention in care for pediatric cancer patients in SSA.

Abstract Primary gastrointestinal lymphoma (PGIL) is a rare malignant tumor without standard diagnosis and treatment methods. This study is aimed to systematically analyze its clinical characteristics and draw out an appropriate flow chart of diagnosis and treatment process for PGIL in China. This study retrospectively analyzed the clinicopathological characteristics, diagnostic approaches, prognostic factors, and therapeutic modalities in 415 cases of PGIL in Chinese province of Guangdong. A systematic review was conducted in 118 studies containing 5075 patients to further identify clinical manifestations and mortalities of therapeutic modalities. The most common clinical presentations were abdominal pain and bloody stools. Endoscopic biopsy was an important diagnostic means, and usually more than once to make a definite diagnosis. Retrospective multicenter clinical study showed that younger onset age (<60 years), female, one region involved, one lesion, early stage, International Prognostic Index (IPI ≤1), normal lactate dehydrogenase (LDH), normal albumin, and nonemergency operation were significant prognostic factors for B-cell lymphoma; non-B symptom, tumor restricted to gastric or ileocecal region, one lesion, performance status (PS ≤1), normal LDH, and nonsurgery alone were significant prognostic factors for T-cell lymphoma. Site of origin and IPI were independent prognostic factors for B-cell lymphoma; PS was the independent prognostic factor for T-cell lymphoma. And T-cell lymphoma had worse overall survival (OS) and progression-free survival (PFS) than B-cell lymphoma. Among different therapeutic modalities, chemotherapy alone or combined with surgery showed better OS and PFS than surgery alone for diffuse large B-cell lymphoma (DLBCL) of stage I/II E and T-cell lymphoma. For DLBCL of stage III E/IV and mucosa-associated lymphoid tissue lymphoma, OS and PFS did not differ among different therapeutic groups. In meta-analysis, surgery plus chemotherapy

To determine consequences of lymphoma treatments on sperm characteristics and sperm DNA, and to evaluate predictors of sperm recovery. Multicenter prospective longitudinal study of patients analyzed before treatment and after 3, 6, 12, and 24 months. University hospitals. Seventy-five Hodgkin lymphoma and non-Hodgkin lymphoma patients and a control group of 257 fertile men. Semen analyses, and sperm DNA and chromatin assessments. Comparisons of sperm characteristics before and after treatment. Patients already had altered sperm characteristics before lymphoma treatment, with no identified risk factor. Sperm count, total sperm count, motility, and vitality decreased after treatment, with lowest values at 3 and 6 months. Twelve months after treatment, mean sperm count recovered to pretreatment values after doxorubicin, bleomycin, vinblastine, darcarbacine (ABVD) or ABVD+radiotherapy, but not after doxorubicin, cyclophosphamide, vincristine, prednisone (CHOP) or mechlorethamine, oncovin, procarbazine, prednisone (MOPP) chemotherapies. It was noteworthy that 7% of patients remained azoospermic at 24 months. After 24 months, Kaplan-Meier estimates showed that more than 90% of patients will recover normal sperm count after ABVD or ABVD+radiotherapy vs. 61% for CHOP chemotherapies. In multivariate analyses including diagnosis and treatment protocol, only pretreatment total sperm count was related to recovery. Compared with a control group, lymphoma patients had higher sperm chromatin alterations and DNA fragmentation before any treatment. After treatment, DNA fragmentation assessed by TUNEL assay and sperm chromatin structure assay decreased from 3 and 6 months, respectively, while remaining higher than in the control group during follow-up. Lymphoma patients had altered sperm DNA and chromatin before treatment. Lymphoma treatment had damaging effects on spermatogenesis. These data on both the recovery period according to treatment modalities and the pre- and post-treatment

The incidence of non-Hodgkin's lymphoma and Hodgkin's lymphoma is higher in patients with HIV infection than in the general population. Following the introduction of combination antiretroviral therapy (cART), the prognostic significance of HIV-related variables has decreased, and lymphoma-related factors have become more pronounced. Currently, treatments for lymphomas in HIV-infected patients do not differ from those used in the general population. However, differentiating characteristics of seropositive patients, such as the need for cART and specific prophylaxis and treatment of certain opportunistic infections, should be considered.

Purpose: Involved-field radiation therapy of the stomach is often used in the curative treatment of gastric lymphoma. Yet, the optimal technique to irradiate the stomach with minimal morbidity has not been well established. This study was designed to evaluate treatment planning alternatives for stomach irradiation, including intensity-modulated radiation therapy (IMRT), to determine which approach resulted in improved dose distribution and to identify patient-specific anatomic factors that might influence a treatment planning choice. Methods and Materials: Fifteen patients with lymphoma of the stomach (14 mucosa-associated lymphoid tissue lymphomas and 1 diffuse large B-cell lymphoma) were categorized into 3 types, depending onmore » the geometric relationship between the planning target volume (PTV) and kidneys. AP/PA and 3D conformal radiation therapy (3DCRT) plans were generated for each patient. IMRT was planned for 4 patients with challenging geometric relationship between the PTV and the kidneys to determine whether it was advantageous to use IMRT. Results: For type I patients (no overlap between PTV and kidneys), there was essentially no benefit from using 3DCRT over AP/PA. However, for patients with PTVs in close proximity to the kidneys (type II) or with high degree of overlap (type III), the 4-field 3DCRT plans were superior, reducing the kidney V {sub 15Gy} by approximately 90% for type II and 50% for type III patients. For type III, the use of a 3DCRT plan rather than an AP/PA plan decreased the V {sub 15Gy} by approximately 65% for the right kidney and 45% for the left kidney. In the selected cases, IMRT led to a further decrease in left kidney dose as well as in mean liver dose. Conclusions: The geometric relationship between the target and kidneys has a significant impact on the selection of the optimum beam arrangement. Using 4-field 3DCRT markedly decreases the kidney dose. The addition of IMRT led to further incremental improvements in the left

Epidemiologic overview of malignant lymphoma

PubMed Central

2012-01-01

Malignant lymphoma encompasses a wide variety of distinct disease entities. It is generally more common in developed countries and less common in developing countries. The East Asia region has one of the lowest incidence rates of malignant lymphoma. The incidence of malignant lymphoma around the world has been increasing at a rate of 3-4% over the last 4 decades, while some stabilization has been observed in developed countries in recent years. The reasons behind this lymphoma epidemic are poorly understood, although improving diagnostic accuracy, the recent AIDS epidemic, an aging world population and the increasing adoption of cancer-causing behaviors are suggested as contributing factors. Etiologies of malignant lymphoma include infectious agents, immunodeficiency, autoimmune disease, exposure to certain organic chemicals, and pharmaceuticals. The distribution of many subtypes exhibit marked geographic variations. Compared to the West, T/natural killer (NK) cell lymphomas (T/NK-cell lymphoma) and extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) are relatively more common, whereas other B-cell lymphomas, particularly follicular lymphoma and chronic lymphocytic leukemia/small lymphocytic lymphoma, are less common in Asia. Some subtypes of T/NK-cell lymphomas defined by Epstein-Barr virus association are predominantly Asian diseases, if not exclusively so. Both ethnic and environmental factors play roles in such diversity. In this review, we discuss the geographic distribution and etiology of malignant lymphoma, as well as the trend. PMID:22783355

Gastric MALT lymphoma: old and new insights

The stomach is the most frequent site of extranodal lymphoma. Gastric lymphoma originating from mucosa-associated lymphoid tissue (MALT) is typically a low-grade, B-cell neoplasia strongly associated with Helicobacter pylori (H. pylori) infection. Only certain H. pylori strains in some predisposed patients determine lymphoma development in the stomach, according to a strain-host-organ specific process. The clinical presentation is poorly specific, symptoms ranging from vague dyspepsia to alarm symptoms. Similarly, different endoscopy patterns have been described for gastric lymphoma. H. pylori eradication is advised as first-line therapy in early stage disease, and complete lymphoma remission is achieved in 75% of cases. Neoplasia stage, depth of infiltration in the gastric wall, presence of the API2-MALT1 translocation, localization in the stomach, and patient ethnicity have been identified as predictors of remission. Recent data suggests that H. pylori eradication therapy may be successful for gastric lymphoma treatment also in a small subgroup (15%) of H. pylori-negative patients. The overall 5-year survival and disease-free survival rates are as high as 90% and 75%, respectively. Management of patients who failed to achieve lymphoma remission following H. pylori eradication include radiotherapy, chemotherapy and, in selected cases, surgery. PMID:24714739

A 75-year-old man was referred to our hospital for evaluation of persistent anemia. Despite repeated diagnostic tests, including bone marrow aspiration, the cause of his anemia remained unknown. On each occasion, computed tomography had revealed neither swollen lymph nodes nor splenomegaly. After a 10-year follow-up period, he was admitted with general fatigue and had developed splenomegaly as well as the anemia. Bone marrow biopsy revealed increased abnormal lymphocytes with short villi that were positive for CD11c, CD19, CD20, and kappa chain, but not for CD5, CD10, CD23, or cyclin D1, according to flow cytometry. The bone marrow biopsy sample showed nodular proliferation of small to medium-sized abnormal lymphocytes. Based on these findings, the patient was diagnosed as having splenic marginal zone lymphoma, a rare indolent B-cell neoplasm. Although his splenomegaly diminished after eight cycles of weekly rituximab monotherapy, the anemia did not improve, and abnormal lymphocytes remained detectable in his bone marrow. The patient was then treated with bendamustine monotherapy for six cycles, after which the anemia resolved, and he has since been in good condition. Although rare, it is important to consider splenic marginal zone lymphoma during the differential diagnosis of patients with a long history of anemia of unknown cause.

Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of diffuse large B-cell lymphoma. There have been only a limited number of reports regarding pituitary dysfunction associated with IVLBCL. We present a 71-year-old woman with hypopituitarism without any hypothalamic/pituitary abnormalities as assessed by magnetic resonance imaging. She presented with edema, abducens palsy, and elevated levels of lactate dehydrogenase and soluble interleukin-2 receptor. Provocative testing showed that the peaks of luteinizing hormone, follicle-stimulating hormone, thyroid-stimulating hormone and adrenocorticotropic hormone were evoked to normal levels by simultaneous administration of luteinizing hormone-releasing hormone, thyrotropin-releasing hormone and corticotropin-releasing hormone, but the responses of these four pituitary hormones showed a delayed pattern. She was diagnosed with IVLBCL with cerebrospinal invasion by pathological findings of the bone marrow, skin, and cerebrospinal fluid. She achieved hematological remission after immunochemotherapy. Pituitary function was also restored without hormonal replacement, and the improvement of the pituitary function was confirmed by dynamic testing. We reviewed the literature with respect to hypopituitarism associated with IVLBCL. There were less than 20 case reports and most of the patients died. Endocrinological course was described in only two cases, and both of them required hormonal supplementation. To our knowledge, this is the first case of hypopituitarism induced by IVLBCL that was successfully managed by immunochemotherapy alone. This case suggests that early diagnosis and treatment of IVLBCL might improve anterior pituitary function and enable patients to avoid hormone replacement therapy.

Nodal marginal zone lymphoma (NMZL) represents a rare and heterogeneous group that lacks markers specific for the diagnosis. We evaluated morphologic and immunoarchitectural features of 51 NMZLs, and the following immunostains were performed: CD20, CD21, CD23, CD5, CD3, CD43, CD10, Ki-67, BCL1, BCL2, BCL6, HGAL, and LMO2. Four immunoarchitectural patterns were evident: diffuse (38 [75%]), well-formed nodular/follicular (5 [10%]), interfollicular (7 [14%]), and perifollicular (1 [2%]). Additional features included a monocytoid component (36 [71%]), admixed large cells (20 [39%]), plasma cells (24 [47%]), compartmentalizing stromal sclerosis (13 [25%]), and prominent blood vessel sclerosis (10 [20%]). CD21 highlighted disrupted follicular dendritic cell meshwork in 35 (71%) of 49 cases, and CD43 coexpression was present in 10 (24%) of 42 cases. A panel of germinal center-associated markers was helpful in eliminating cases of diffuse follicle center lymphoma. Our results highlight the histologic and immunoarchitectural spectrum of NMZL and the usefulness of immunohistochemical analysis for CD43, CD23, CD21, BCL6, HGAL, and LMO2 in the diagnosis of NMZL.

Nodular lymphocyte predominant Hodgkin lymphoma represents a distinct entity from classical Hodgkin lymphoma. We conducted a retrospective study to investigate the management of patients with nodular lymphocyte predominant Hodgkin lymphoma. Clinical characteristics, treatment and outcome of adult patients with nodular lymphocyte predominant Hodgkin lymphoma were collected in Lymphoma Study Association centers. Progression-free survival (PFS) and overall survival (OS) were analyzed, and the competing risks formulation of a Cox regression model was used to control the effect of risk factors on relapse or death as competing events. Among 314 evaluable patients, 82.5% had early stage nodular lymphocyte predominant Hodgkin lymphoma. Initial management consisted in watchful waiting (36.3%), radiotherapy (20.1%), rituximab (8.9%), chemotherapy or immuno-chemotherapy (21.7%), combined modality treatment (12.7%), or radiotherapy plus rituximab (0.3%). With a median follow-up of 55.8 months, the 10-year PFS and OS estimates were 44.2% and 94.9%, respectively. The 4-year PFS estimates were 79.6% after radiotherapy, 77.0% after rituximab alone, 78.8% after chemotherapy or immuno-chemotherapy, and 93.9% after combined modality treatment. For the whole population, early treatment with chemotherapy or radiotherapy, but not rituximab alone (Hazard ratio 0.695 [0.320–1.512], P=0.3593) significantly reduced the risk of progression compared to watchful waiting (HR 0.388 [0.234–0.643], P=0.0002). Early treatment appears more beneficial compared to watchful waiting in terms of progression-free survival, but has no impact on overall survival. Radiotherapy in selected early stage nodular lymphocyte predominant Hodgkin lymphoma, and combined modality treatment, chemotherapy or immuno-chemotherapy for other patients, are the main options to treat adult patients with a curative intent.

The genetics of Hodgkin lymphoma: an overview and clinical implications.

PubMed

Borchmann, Sven; Engert, Andreas

2017-09-01

The goal of this review is to give an overview of the genetics of classical Hodgkin lymphoma. Copy number changes, somatic mutations, genome-wide association studies, changes in gene expression, familial classical Hodgkin lymphoma and epigenetic changes will be reviewed. In doing so, special focus is placed on the way recent discoveries have influenced clinical research, diagnostics, treatment and remission monitoring. Furthermore, emphasis is put on how these advances can help to advance the treatment of elderly patients who have a markedly worse prognosis than younger patients. Frequent amplifications of the 9p24.1 locus in classical Hodgkin lymphoma could be the basis for the success of immune checkpoint inhibitors targeting PD-1 or PD-L1 in this disease. The same amplification also affects the JAK/STAT pathway, which has also been targeted in recent clinical trials. Hodgkin lymphoma-specific copy number alterations and mutations have recently been found to be detectable in cell-free DNA. This could provide the basis for advances in the detection of residual disease during treatment and while monitoring patients in remission. The advent of new technologies such as massive parallel sequencing has improved our understanding of the genetics of classical Hodgkin lymphoma. Some of these discoveries are now being translated into clinical research in the form of new diagnostics and treatments.

Treatment of Peripheral T-Cell Lymphoma: Many Shades of Gray.

PubMed

Lunning, Matthew A

2015-08-01

Previously obscured within other designations of aggressive lymphomas, peripheral T-cell lymphoma (PTCL) now represents 23 different subtypes of non-Hodgkin lymphoma (NHL). Despite the many subtypes now recognized, PTCL represents only approximately 10% of all NHL cases diagnosed. Positron emission tomography/computed tomography has become essential to accurate staging and response-evaluation for PTCL. In comparison to aggressive B-cell NHL, patients with PTCL will more often be refractory to initial therapy, and chemosensitive patients will have shorter disease-free periods. Anthracycline-based regimens, often with the inclusion of etoposide, are commonly used during induction therapy. Consolidation with high-dose therapy and autologous stem cell transplantation (ASCT) in first chemosensitive remission appears to provide the best outcome in common nodal PTCL subtypes. The commonly defined nodal subtypes are PTCL not otherwise specified, angioimmunoblastic T-cell lymphoma, and anaplastic lymphoma kinase (ALK)-positive or ALK-negative anaplastic large-cell lymphoma (ALCL). Four agents have been approved by the US Food and Drug Administration for use in the relapsed/refractory (rel/ref) setting, including belinostat (2014), romidepsin (2011), brentuximab vedotin (2011), and pralatrexate (2009). Brentuximab vedotin was approved only for the ALCL subtype. These agents continue to be studied as combinations in the rel/ref setting and as additions or substitutions for other agents in upfront multiagent chemotherapy regimens. Patients who have responded to treatment in the rel/ref setting and are considered transplant-eligible should be considered for allogeneic stem cell transplantation, especially those with previous ASCT. Upfront allogeneic stem cell transplantation remains a research question in the majority of PTCL subtypes, but data are emerging.

Lymphomas are classified according to the World Health Organisation (WHO) classification which defines subtypes on the basis of clinical, morphological, immunophenotypic, molecular and cytogenetic criteria. Differential diagnosis of the subtypes is sometimes difficult, especially for small B-cell lymphoma (SBCL). Standardisation of molecular genetic assays using multiple gene expression analysis by microarrays could be a useful complement to the current diagnosis. The aim of the present study was to develop a low density DNA microarray for the analysis of 107 genes associated with B-cell non-Hodgkin lymphoma and to evaluate its performance in the diagnosis of SBCL. A predictive tool based on Fisher discriminant analysis using a training set of 40 patients including four different subtypes (follicular lymphoma n = 15, mantle cell lymphoma n = 7, B-cell chronic lymphocytic leukemia n = 6 and splenic marginal zone lymphoma n = 12) was designed. A short additional preliminary analysis to gauge the accuracy of this signature was then performed on an external set of nine patients. Using this model, eight of nine of those samples were classified successfully. This pilot study demonstrates that such a microarray tool may be a promising diagnostic approach for small B-cell non-Hodgkin lymphoma.

2-[18F]fluoro-2-deoxyglucose positron-emission tomography in staging, response evaluation, and treatment planning of lymphomas.

PubMed

Specht, Lena

2007-07-01

2-[18F]fluoro-2-deoxyglucose positron-emission tomography (FDG-PET) is used increasingly in the clinical management of lymphomas. With regard to staging, FDG-PET is more sensitive and specific than conventional staging methods in FDG avid lymphomas (ie, Hodgkin lymphoma and most aggressive non-Hodgkin lymphomas). Despite methodological problems, in particular the lack of a valid reference test, FDG-PET is approved and generally used for this purpose. With regard to response evaluation, FDG-PET at the end of treatment seems to aid considerably in differentiating between residual masses with or without residual lymphoma. Hence, new revised response criteria have been proposed, incorporating the result of FDG-PET at the end of treatment. An early interim FDG-PET scan after 1 to 3 cycles of chemotherapy is a very strong predictor of outcome, and trials are now in progress testing treatment modifications on this basis. With regard to treatment planning, in the context of combined-modality therapy, radiotherapy for lymphomas is moving toward more conformal techniques reducing the irradiated volume to include only the macroscopic lymphoma. In this situation, accurate imaging is essential, and FDG-PET coregistered with the planning computed tomography (CT) scan is used increasingly. The availability of PET/CT scanners suited for virtual simulation has aided this process. However, clinical data evaluating this technique are at present sparse.

Clinical and histopathological characteristics of 16 dogs with nodal paracortical (T-zone) lymphoma (TZL) were evaluated. At initial examination, generalized lymphadenopathy was found in all dogs, and peripheral lymphocytosis was found in 10 of the 16 dogs. At initial diagnosis or during the disease course, 8 dogs (50%) were affected with demodicosis. Immunohistochemical analysis for CD3, CD20 and CD25 was performed for 6 dogs with TZL; the tumor cells were positive for CD3 and CD25 and negative for CD20. Median overall survival time was 938 days. A watchful waiting approach was adopted for 6 cases (38%), and 5 of the 6 dogs were still alive at the end of follow-up. The clinical course of TZL in dogs is generally indolent; however, many cases develop a variety of infectious and other neoplastic diseases after the diagnosis of TZL. PMID:27098109

Idelalisib for the treatment of non-Hodgkin lymphoma

PubMed Central

Gopal, Ajay; Graf, Solomon

2016-01-01

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

2014-01-01

Leukemia and lymphoma are systemic malignancies that represent half of all childhood cancers, though 90% occur in adults. Various treatment options are available, but therapy is mainly systemic chemotherapy plus appropriate monoclonal antibodies. In certain situations radiotherapy and bone marrow transplantation play a role. Some types/subtypes of these diseases are potentially curable, yet many leukemias and lymphomas do not properly respond to current therapies. Although the FDA (US Food and Drugs Administration) approvals of new drugs have shown a small increasing trend between 2007-2012, overall, the trend of new approvals remains relatively steady between 2006-2013, with a peak of 39 new drugs approved in 2012 and a drop in the new FDA drug approvals in 2013, to 27. Drugs approved for cancer treatment have shown a similar trend. Between 2006-2013, at least one drug was approved every year for the treatment of particular types of lymphoma or leukemia, except in 2010, with a peak of 5 new approvals in 2012. Between January 2013-March 2014, several important new approvals were made: ibrutinib for the treatment of CLL and mantle cell lymphoma (MCL), obinutuzumab for the treatment of CLL (in combination with chlorambucil), and lenalidomide for the treatment of mantle cell lymphoma. The results, importance, adverse effects and mechanisms of action of these agents are discussed in this review. These results held promise and their discovery and approval for the treatment of CLL and MCL is a major step forward. However, the emergence of resistance and the lack of cures need to be addressed by rational development of combination therapy, as well as development of novel drugs with enhanced potency or different mechanism of action, to achieve better overall and complete response rates with decreased toxicity.

Non-Hodgkin lymphoma comprises a heterogeneous group of haematological malignancies, classified according to their clinic, anatomic-pathological features and, lately, to their molecular biomarkers. Despite the therapeutic advances, nearly half of the patients will die because of this disease. The new diagnostic tools have been the cornerstone to design recent therapy targets, which must be included in the current treatment guidelines of this sort of neoplasms by means of clinical trials and evidence-based medicine. In the face of poor diagnoses devices in most of the Mexican hospitals, we recommend the present diagnose stratification, and treatment guidelines for non-Hodgkin lymphoma, based on evidence. They include the latest and most innovative therapeutic approaches, as well as specific recommendations for hospitals with limited framework and therapy resources.

Efficacy of celecoxib in the treatment of CNS lymphomas: an in vivo model.

The incidence of primary central nervous system lymphomas (PCNSLs) has increased over the past several decades. Unfortunately, even with the most effective therapeutic regimen (that is, methotrexate with wholebrain radiation therapy), PCNSL recurs within a few years in more than half of the treated patients and is eventually fatal. Because PCNSL usually occurs in older patients and in those with acquired immunodeficiency syndrome, combination treatments in which both chemo- and radiation therapy are used is often poorly tolerated and results in a significant reduction in the quality of life. Recently, it has been demonstrated that the selective cyclooxygenase- 2 inhibitor celecoxib (Celebrex), can block the growth of lymphoma cells in vitro. To create an experimental animal model in vivo for the PCNSL study, the authors intracranially injected a human B-cell lymphoma cell line into nude mice. Their data demonstrate that this experimental model is an excellent one for human PCNSL with brain and leptomeningeal involvement. They also evaluated the feasibility of using celecoxib as a therapeutic agent in the treatment of PCNSL. Nude mice with intracranial lymphomas were treated with celecoxib contained in the animal chow. The treated animals demonstrated significantly prolonged survival times compared with the untreated animals. Based on the authors' data, celecoxib may be a promising therapeutic agent for the treatment of PCNSL.

Molecular Pathogenesis of MALT Lymphoma

PubMed Central

Troppan, Katharina; Wenzl, Kerstin; Neumeister, Peter; Deutsch, Alexander

2015-01-01

Approximately 8% of all non-Hodgkin lymphomas are extranodal marginal zone B cell lymphoma of mucosa associated lymphoid tissue (MALT), also known as MALT lymphoma, which was first described in 1983 by Isaacson and Wright. MALT lymphomas arise at a wide range of different extranodal sites, with the highest frequency in the stomach, followed by lung, ocular adnexa, and thyroid, and with a low percentage in the small intestine. Interestingly, at least 3 different, apparently site-specific, chromosomal translocations and missense and frameshift mutations, all pathway-related genes affecting the NF-κB signal, have been implicated in the development and progression of MALT lymphoma. However, these genetic abnormalities alone are not sufficient for malignant transformation. There is now increasing evidence suggesting that the oncogenic product of translocation cooperates with immunological stimulation in oncogenesis, that is, the association with chronic bacterial infection or autoaggressive process. This review mainly discusses MALT lymphomas in terms of their genetic aberration and association with chronic infections and summarizes recent advances in their molecular pathogenesis. PMID:25922601

Extranodal natural killer/T-cell lymphomas (NK/TL), rare in Europe, are Epstein-Barr virus (EBV) associated lymphomas with poor outcomes. Here, we determined the virus type and analyzed the EBV latent membrane protein-1 (LMP1) gene sequence in NK/TL from French patients. Six clones of viral LMP1 were sequenced by Sanger technology in blood from 13 patients before treatment with an l-asparaginase based regimen and, for 8 of them, throughout the treatment. Blood LMP1 sequences from 21 patients without any known malignancy were tested as controls. EBV Type A was identified for 11/13 patients and for all controls. Before treatment, a clonal LMP1 gene containing a 30 bp deletion (del30) was found in 46.1% of NK/TL and only in 4.8% of controls. Treatment was less effective in these patients who died more rapidly than the others. Patients with a deleted strain evolving toward a wild-type strain during treatment reached complete remission. The LMP1 gene was sequenced by highly sensitive next-generation sequencing technology in five NK/TL nasopharyngeal biopsies, two of them originating from the previous patients. Del30 was present in 100% of the biopsies; two viruses at least coexisted in three biopsies. These results suggest that del30 may be associated with poor prognosis NK/TL and that strain evolution could be used as a potential marker to monitor treatment. © 2016 UICC.

Sofosbuvir-based therapy cures hepatitis C virus infection after prior treatment failures in a patient with concurrent lymphoma.

We report on the first well-tolerated and successful use of sofosbuvir-based therapy in a patient in whom chronic infection with hepatitis C had preceded the development of B-cell non-Hodgkin's lymphoma. The patient had previously failed numerous attempts to clear the hepatitis C virus with traditional antiviral schedules. We demonstrate that sofosbuvir-based therapy resulted in cure of hepatitis C in a patient who had relapsed during combination therapy with an NS5A inhibitor, an NS3 protease inhibitor and ribavirin, as well as treatment failures to multiple courses of interferon-based therapy. This report also suggests that eradication of hepatitis C virus may result in the short-term prevention of B-cell non-Hodgkin's lymphoma relapse. The findings from our case require further validation in future cohorts of patients. Copyright © 2015 Elsevier B.V. All rights reserved.

Concurrent colonic mucosa-associated lymphoid tissue lymphoma and adenoma diagnosed after a positive fecal occult blood test: a case report.

Colonic lymphoma is an uncommon presentation of extranodal lymphoma. Colonic mucosa-associated lymphoid tissue lymphoma is a different entity from gastric mucosa-associated lymphoid tissue lymphoma, and very rare. The presentation and management of colonic mucosa-associated lymphoid tissue are highly variable in the literature. We report the case of a 59-year-old Taiwanese man who underwent a colonoscopy after a positive test for fecal occult blood. His past history included hypertension and hyperthyroidism. The colonoscopy revealed an adenomatous polyp and mucosa-associated lymphoid tissue lymphoma. We successfully performed a polypectomy and endoscopic mucosal resection. The lymphoma was staged according to the Ann Arbor system modified by Musshoff as E-I. Our patient showed no lymphoma recurrence over a 3-year follow-up. Endoscopic mucosal resection for colonic mucosa-associated lymphoid tissue lymphoma without disseminated disease may be feasible. We successfully used colonoscopic treatment without adjuvant therapy to treat early-stage pathogen-free colonic mucosa-associated lymphoid tissue lymphoma.

A 45-year-old woman was diagnosed with essential thrombocythemia (ET) in August 1987 and received treatment with alkylating agents (total administration dose, busulfan 378 mg, MCNU 700 mg) because of a history of myocardial infarction. In June 2000, anemia gradually progressed. A few blast cells were detected in the peripheral blood at that time. Since bone marrow biopsy revealed myelofibrosis, she received anabolic hormone therapy. She was admitted to our hospital for an evaluation of abdominal distension in February 2003. Swelling of a large paraaortic lymph node of 6 cm in diameter was detected by CT scan. Lymph node biopsy revealed diffuse large B-cell lymphoma. Lymphoma cells were positive for CD10, CD19, CD20 and kappa-chain. The clinical stage was I. Complete remission has been achieved for 57 months after treatment with combination chemotherapy combined with rituximab followed by local radiation therapy. Non-Hodgkin lymphoma secondary to ET is a rare event. Such cases should therefore be accumulated to evaluate the mechanism of onset and clinical characteristics of lymphoma secondary to ET.

Evaluation of a 15-week CHOP protocol for the treatment of canine multicentric lymphoma.

Dose intense CHOP protocols have been shown to improve outcome for people with non-Hodgkin's lymphoma, but evaluation of dose intense CHOP protocols for canine lymphoma is currently limited. The hypothesis of this retrospective study was that a 15-week dose intense CHOP protocol would have shorter treatment duration with similar efficacy to other doxorubicin-based multidrug protocols. Thirty-one client owned dogs with multicentric lymphoma were treated with a 15-week CHOP chemotherapy protocol with an overall response rate of 100% and a median progression-free interval (PFI) of 140 days [95% confidence interval (CI) 91-335 days]. Dogs that had two or more treatment delays had significantly prolonged PFI and overall survival in multivariate analysis. Dose intensity did not correlate with patient outcome. Dogs experiencing multiple treatment delays secondary to adverse events may receive their individual maximally tolerated dose while dogs with no adverse events may be underdosed. Future studies should focus on individual patient dose optimization. © 2012 Blackwell Publishing Ltd.

Only a small number of patients with aggressive B-cell lymphoma take part in clinical trials, and elderly patients in particular are under-represented. Therefore, we studied data of the population-based nationwide Netherlands Cancer Registry to determine trends in incidence, treatment and survival in an unselected patient population. We included all patients aged 15 years and older with newly diagnosed diffuse large B-cell lymphoma or Burkitt lymphoma in the period 1989–2010 and mantle cell lymphoma in the period 2001–2010, with follow up until February 2013. We examined incidence, first-line treatment and survival. We calculated annual percentage of change in incidence and carried out relative survival analyses. Incidence remained stable for diffuse large B-cell lymphoma (n=23,527), while for mantle cell lymphoma (n=1,634) and Burkitt lymphoma (n=724) incidence increased for men and remained stable for women. No increase in survival for patients with aggressive B-cell lymphoma was observed during the period 1989–1993 and the period 1994–1998 [5-year relative survival 42% (95%CI: 39%–45%) and 41% (38%–44%), respectively], but increased to 46% (43%–48%) in the period 1999–2004 and to 58% (56%–61%) in the period 2005–2010. The increase in survival was most prominent in patients under 65 years of age, while there was a smaller increase in patients over 75 years of age. However, when untreated patients were excluded, patients over 75 years of age had a similar increase in survival to younger patients. In the Netherlands, survival for patients with aggressive B-cell lymphoma increased over time, particularly in younger patients, but also in elderly patients when treatment had been initiated. The improvement in survival coincided with the introduction of rituximab therapy and stem cell transplantation into clinical practice. PMID:25512643

Treatment of lymphoma in dogs by long-term chemotherapy has favorable results. However, the efficacy of short-term, maintenance-free treatment protocols on remission and survival times in dogs has not been determined. That treatment using a 12-week chemotherapy protocol would be associated with satisfactory treatment outcome in dogs with lymphoma. 77 dogs with histologically or cytologically confirmed diagnosis of lymphoma. Prospective clinical trial in which dogs were treated with a 12-week chemotherapy protocol consisting of L-asparaginase, vincristine, cyclophosphamide, doxorubicin, and prednisolone. Complete remission rate was 76.3%. Multivariate logistic regression analysis revealed that clinical substage (P = .006) and immunophenotype (P = .003) had a significant influence on the likelihood of a dog achieving complete remission. Median duration of first complete remission was 243 days (range 19-1,191 days). The 6-month, 1-year, and 2-year remission rates were 68%, 28%, and 16%, respectively. In the multivariate analysis of patient variables, immunophenotype (P = .022) revealed a significant influence on first remission duration. Toxicosis was mild with the exception of 1 treatment-associated death. In this group of dogs the 12-week maintenance-free chemotherapy protocol was well tolerated and had satisfactory results.

AIM: To determine clinical characteristics and treatment outcome of gastric lymphoma after chemotherapy and immuno-chemotherapy. METHODS: Thirty four patients with primary gastric mucosa associated lymphoid tissue (MALT) lymphoma (Ann Arbor stages I to IV) were enrolled. All had upper gastric endoscopy, abdominal ultrasonography, CT and H pylori status assessment (histology and serology). After anti-H pylori treatment and initial chemotherapy, patients were re-examined every 4 mo. RESULTS: Histological regression of the lymphoma was complete in 22/34 (64.7%) and partial in 9 (26.5%) patients. Median follow up time for these 31 responders was 60 mo (range 48-120). No regression was noted in 3 patients. Among the 25 (73.5%) H pylori positive patients, the eradication rate was 100%. CONCLUSION: Using univariate analysis, predictive factors for overall survival were international prognostic index (IPI) score, hemoglobin level, erythrocyte sedimentation rate (ESR), and platelet numbers (P < 0.005). In addition to this, Cox proportion hazard model differentiate IPI score, ESR, and platelets as predictors of survival. PMID:18416467

Background Follicular lymphoma is the second most common non-Hodgkin lymphoma in the United States and Europe. However, most of the prospective randomized studies have very little follow-up compared to the long natural history of the disease. The primary aim of this study was to investigate the long-term survival of our series of patients with follicular lymphoma. Patients and methods A total of 1074 patients with newly diagnosed FL were enrolled. Patients diagnosed were prospectively enrolled from 1980 to 2013. Results Median follow-up was 54.9 months and median overall survival is over 20 years in our series. We analyzed the patients who are still alive beyond 10 years from diagnosis in order to fully assess the prognostic factors that condition this group. Out of 166 patients who are still alive after more than 10 years of follow-up, 118 of them (73%) are free of evident clinical disease. Variables significantly associated with survival at 10 years were stage < II (p <0.03), age < 60 years (p <0.0001), low FLIPI (p <0.002), normal β2 microglobulin (p <0.005), no B symptoms upon diagnosis (p <0.02), Performance Status 0–1 (p <0.03) and treatment with anthracyclines and rituximab (p <0.001), or rituximab (p <0.0001). Conclusions A longer follow-up and a large series demonstrated a substantial population of patients with follicular lymphoma free of disease for more than 10 years. PMID:28493986

Methotrexate induces high level of apoptosis in canine lymphoma/leukemia cell lines.

Methotrexate is an antimetabolite used in the treatment of cancer and non-malignant diseases including rheumatoid arthritis, psoriasis and graft vs. host disease. Combination therapy with methotrexate was successful in the treatment of canine lymphoma, mammary tumor and invasive urinary bladder cancer. Lymphoma, the most common hematopoietic cancer in dogs, and leukemia are sensitive to chemotherapy, which is why methotrexate may be an important treatment option for these diseases. Although methotrexate is already used in veterinary oncology its effects on canine cancer cells has not been tested. The aim of the study was to evaluate for the first time methotrexate concentration-dependent cytotoxicity and its capability of inducing apoptosis in selected canine lymphoma/leukemia cell lines: CLBL-1, GL-1 and CL-1 as a first step before the in vitro development of new therapeutic options with the use of methotrexate. Methotrexate exhibited concentration-dependent inhibitory effect on proliferation of all the examined cell lines with different degree of apoptosis induction. The most methotrexate sensitive cells belonged to CL-1 cell line derived from T cell neoplasia and previously characterized by high resistance to the majority of anticancer drugs used in the therapy of lymphoma/leukemia in dogs. Canine lymphoma and leukemia cell lines are sensitive to methotrexate, and this drug may be useful in effective treatment of canine neoplasms and especially of T-type leukemia/lymphoma.

Pleotropic-glycoprotein (P-gp)-mediated resistance is the usual cause of relapse in dogs with lymphoma. 1-(2-chloroethyl)3-cyclohexyl-1-nitrosurea (CCNU) and 5-(3,3-dimethyl-1-triazeno)-imidazole-4-carboxamide (DTIC) are alkylating agents that are not affected by P-gp and lack cross-resistance to each other. A combination protocol offers the advantage of improved summation dose and synergistic activity. A combination of CCNU and DTIC that is well tolerated can be used to treat dogs with lymphoma that developed resistance or failed to respond to previously administered chemotherapy. Fifty-seven dogs with lymphoma that were resistant to treatment with standard chemotherapy (L-CHOP; L-asparaginase, cyclophosphamide, doxorubicin, vincristine, prednisone). Prospective phase I and II trials were performed. CCNU was given PO immediately before a 5-h IV infusion of DTIC. Concurrent antiemetics and prophylactic antibiotics were used. Treatments were administered every 4 weeks. Based on the results of 8 dogs in the phase I study, CCNU at 40 mg/m(2) PO combined with DTIC at 600 mg/m(2) IV was used to treat 57 dogs with resistant lymphoma. Thirteen (23%) dogs had a complete response (CR) for a median of 83 days and 7 (12%) had a partial response for a median of 25 days. The median L-CHOP CR duration of the dogs that did not respond to CCNU-DTIC was significantly longer than that of the dogs that did achieve remission with CCNU-DTIC (225 days versus 92 days, P= .02). The principal toxic event was neutropenia; the median neutrophil count 7 days after treatment was 1,275 cells/microL. Increases in alanine transaminase activity, possibly associated with hepatotoxicity, were detected in 7 dogs. A combination of CCNU and DTIC can be an effective option to rescue dogs with resistant lymphoma.

Purpose: To determine the efficacy of low-dose palliative radiotherapy for both low-grade malignant cutaneous B-cell lymphomas (CBCLs) and cutaneous T-cell lymphomas (mycosis fungoides). Methods and Materials: A total of 18 patients with low-grade CBCL (10 primary cutaneous marginal zone B-cell and 8 primary cutaneous follicle center lymphomas) with 44 symptomatic plaques and tumors underwent low-dose (4 Gy in two fractions) local radiotherapy. A total of 31 patients with mycosis fungoides were treated at 82 symptomatic sites, initially with 4 Gy and later with 8 Gy in two fractions. Results: The complete response rate for CBCL lesions was 72%. Of themore » 44 B-cell lymphoma lesions, 13 were re-treated to the same site after a median of 6.3 months because of persistent (n = 8) or recurrent (n = 5) symptomatic disease. Of the mycosis fungoides patients treated with 4 Gy in two fractions (17 lesions), 70% failed to respond. Increasing the dose to 8 Gy in two fractions yielded a complete response rate of 92% (60 of 65 lesions). The patients in whom low-dose radiotherapy failed were retreated with 20 Gy in eight fractions. Conclusion: Our results have demonstrated that low-dose involved-field radiotherapy induces a high response rate in both CBCL and cutaneous T-cell lymphoma lesions without any toxicity. Therefore, this treatment is now our standard palliative treatment. At progression, it is safe and feasible to apply greater radiation doses.« less

In this Grand Round we present a 32-yr-old African man who became severely ill after a 5-month history of weight loss, pyrexia, arthralgia, sweats and rash. He went on to develop pericarditis, pericardial effusion with tamponade, hepatomegaly with abnormal liver function tests, lymphadenopathy, massive proteinuria and required ventilatory, circulatory and renal support. The differential diagnosis was adult onset Still's disease, systemic lupus erythematosus (SLE), infection and lymphoma. Primary infection and lymphoma were excluded and he was treated, with dramatic success, with intravenous immunoglobulins (i.v.IG). Subsequent renal biopsy excluded SLE but confirmed collapsing glomerulopathy. The proteinuria improved dramatically following treatment with mycophenolate mofetil. We discuss some of the difficult diagnostic and management issues raised by this patient and the different uses and mechanisms of action of i.v.IG.

To determine the incidence and possible causes of second primary malignancies after treatment for Hodgkin's and Non-Hodgkin's lymphoma (HL and NHL). A cohort of 3764 consecutive patients diagnosed with HL or NHL between January 1970 and July 2001 was identified using the Sheffield Lymphoma Group database. A search was undertaken for all patients diagnosed with a subsequent primary malignancy. Two matched controls were identified for each case. Odds ratios were calculated to detect and quantify any risk factors in the cases compared to their matched controls. Mean follow-up for the cohort was 5.2 years. A total of 68 patients who developed second cancers at least 6 months after their primary diagnosis were identified, giving a crude incidence of 1.89% overall: 3.21% among the patients treated for HL, 1.32% in those treated for NHL. Most common were bronchial, breast, colorectal and haematological malignancies. High stage at diagnosis almost reached statistical significance in the analysis of just the NHL patients (odds ratio=3.48; P=0.068) after adjustment for other factors. Treatment modality was not statistically significant in any analysis. High stage at diagnosis of NHL may be a risk factor for developing a second primary cancer. PMID:16106249

Peripheral nodal follicular T-cell lymphomas expressing follicular helper T-cell (T(FH)) markers have recently been identified. Such lymphomas are characterized by a nodal neoplastic T-cell proliferation accompanied by numerous reactive B cells and demonstrate some overlap with nodal angioimmunoblastic T-cell lymphoma (AITL). We identified 5 cases of cutaneous T-cell lymphoma with a peculiar pathologic aspect and expression of T(FH) markers. The mean age of the patients was 61 years (range, 33-78 years). Four patients had multiple papules, plaques, and nodules predominating on the trunk and the head. One had a nodular plaque on the face. Lesional T-cell clonality was found in all 5 patients, and blood T-cell clonality in 4 of the 5. Nodal involvement was never found. Patients had no systemic symptoms and no biological signs of AITL. In 3 cases, findings from skin biopsy specimens were initially misdiagnosed as primary cutaneous follicle B-cell lymphoma due to major B-cell infiltrate and CD10 positivity. Rituximab-containing therapies were ineffective in these cases, and biopsy specimens after treatment with rituximab showed medium- to large-sized atypical T-cell skin infiltrate expressing T(FH) markers (CD10, Bcl-6, PD-1, CXCL13, and ICOS). The final diagnosis proposed for all patients was cutaneous T(FH) lymphoma. The patient with localized disease was successfully treated with radiotherapy. Patients with diffuse disease showed marked resistance to treatments, with only 1 case of complete remission after allogeneic hematopoietic stem cell transplantation followed by bortezomib and donor-lymphocyte infusion. Bexarotene, methotrexate, thalidomide, interferon alfa, gemcitabine, liposomal doxorubicin, or multiagent chemotherapy with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) were either ineffective or induced transitory partial remission. We describe an original clinicopathologic series of primary cutaneous lymphomas with T(FH) phenotype

A 63-year-old man with follicular lymphoma was administered standard R-CHOP chemotherapy. Six days after the second course of chemotherapy, the patient developed fever and chills. Blood cultures yielded rod-shaped gram-negative bacteria, but no further identification was obtained. High fever and chills returned on the fifth and sixth days after the third and fourth courses of R-CHOP, respectively. These blood cultures were also positive. Since we detected spiral-shaped gram-negative rods, we performed a prolonged culture during the febrile period after the fourth course of R-CHOP. This revealed the formation of characteristic film-like colonies, and Helicobacter cinaedi(H. cinaedi)bacteria was identified. After final identification, the patient was administered prophylactic minocycline treatment. Subsequent blood cultures were negative, fever did not recur, and we were able to complete 6 courses of R-CHOP. Although H. cinaedi has been reported to be a cause of sepsis in immunocompromised patients, standard correlation has not been established. Our case suggests that H. cinaedi should be considered when recurrent fever is observed after chemotherapy. Prophylactic antibiotic treatment with minocycline may prevent sepsis, as observed in our case.

Background Marginal zone lymphoma (MZL), comprised of nodal, extranodal, and splenic subtypes, accounts for 5%–10% of non-Hodgkin lymphoma cases. A detailed evaluation of the independent effects of risk factors for MZL and its subtypes has not been conducted. Methods Data were pooled from 1052 MZL cases (extranodal [EMZL] = 633, nodal [NMZL] = 157, splenic [SMZL] = 140) and 13766 controls from 12 case–control studies. Adjusted unconditional logistic regression was used to compute odds ratios (ORs) and 95% confidence intervals (CIs). Results Novel findings for MZL subtypes include increased risk for B-cell activating autoimmune conditions (EMZL OR = 6.40, 95% CI = 4.24 to 9.68; NMZL OR = 7.80, 95% CI = 3.32 to 18.33; SMZL OR = 4.25, 95% CI = 1.49 to 12.14), hepatitis C virus seropositivity (EMZL OR = 5.29, 95% CI = 2.48 to 11.28), self-reported peptic ulcers (EMZL OR = 1.83, 95% CI = 1.35 to 2.49), asthma without other atopy (SMZL OR = 2.28, 95% CI = 1.23 to 4.23), family history of hematologic cancer (EMZL OR = 1.90, 95% CI = 1.37 to 2.62) and of non-Hodgkin lymphoma (NMZL OR = 2.82, 95% CI = 1.33 to 5.98), permanent hairdye use (SMZL OR = 6.59, 95% CI = 1.54 to 28.17), and occupation as a metalworker (NMZL OR = 3.56, 95% CI = 1.67 to 7.58). Reduced risks were observed with consumption of any alcohol (EMZL fourth quartile OR = 0.48, 95% CI = 0.28 to 0.82) and lower consumption of wine (NMZL first to third quartile ORs < 0.45) compared with nondrinkers, and occupation as a teacher (EMZL OR = 0.58, 95% CI = 0.37 to 0.88). Conclusion Our results provide new data suggesting etiologic heterogeneity across MZL subtypes although a common risk of MZL associated with B-cell activating autoimmune conditions was found.

Dural lymphoma (DL) is a rare type of primary CNS lymphoma arising from the dura mater. The optimal treatment is uncertain. A retrospective review was performed on 26 DL patients. Seventeen patients underwent resection and 9 had a biopsy. 23 patients could be assessed for a response to treatment after surgery. 13 received focal radiotherapy (RT), 6 whole brain RT (WBRT), 3 chemotherapy alone and 1 chemotherapy followed by WBRT. 22 achieved complete response (CR) and one a partial response (PR). Four patients relapsed (2 local and 2 systemic). Median follow up was 64 months, with median PFS and OS not reached. Three year PFS was 89% (95% CI 0.64–0.97). All patients are alive at last follow-up, demonstrating that DL is an indolent tumor with long survival. CR is achievable with focal therapy in the majority of cases, but there is a risk for relapses and long-term follow-up is recommended. PMID:27649904

Malignant lymphoma has become an increasingly recognized problem in African lions (Panthera leo). Eleven African lions (9 male and 2 female) with clinical signs and gross and microscopic lesions of malignant lymphoma were evaluated in this study. All animals were older adults, ranging in age from 14 to 19 years. Immunohistochemically, 10 of the 11 lions had T-cell lymphomas (CD3(+), CD79a(-)), and 1 lion was diagnosed with a B-cell lymphoma (CD3(-), CD79a(+)). The spleen appeared to be the primary site of neoplastic growth in all T-cell lymphomas, with involvement of the liver (6/11) and regional lymph nodes (5/11) also commonly observed. The B-cell lymphoma affected the peripheral lymph nodes, liver, and spleen. According to the current veterinary and human World Health Organization classification of hematopoietic neoplasms, T-cell lymphoma subtypes included peripheral T-cell lymphoma (4/11), precursor (acute) T-cell lymphoblastic lymphoma/leukemia (2/11), chronic T-cell lymphocytic lymphoma/leukemia (3/11), and T-zone lymphoma (1/11). The single B-cell lymphoma subtype was consistent with diffuse large B-cell lymphoma. Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) testing by immunohistochemistry on sections of malignant lymphoma was negative for all 11 lions. One lion was seropositive for FeLV. In contrast to domestic and exotic cats, in which B-cell lymphomas are more common than T-cell lymphomas, African lions in this study had malignant lymphomas that were primarily of T-cell origin. Neither FeLV nor FIV, important causes of malignant lymphoma in domestic cats, seems to be significant in the pathogenesis of malignant lymphoma in African lions.

Marginal zone lymphoma (MZL) is a heterogeneous B-cell malignancy for which no standard treatment exists. MZL is frequently linked to chronic infection, which may induce B-cell receptor (BCR) signaling, resulting in aberrant B-cell survival and proliferation. We conducted a multicenter, open-label, phase 2 study to evaluate the efficacy and safety of ibrutinib in previously treated MZL. Patients with histologically confirmed MZL of all subtypes who received ≥1 prior therapy with an anti-CD20 antibody-containing regimen were treated with 560 mg ibrutinib orally once daily until progression or unacceptable toxicity. The primary end point was independent review committee-assessed overall response rate (ORR) by 2007 International Working Group criteria. Among 63 enrolled patients, median age was 66 years (range, 30-92). Median number of prior systemic therapies was 2 (range, 1-9), and 63% received ≥1 prior chemoimmunotherapy. In 60 evaluable patients, ORR was 48% (95% confidence interval [CI], 35-62). With median follow-up of 19.4 months, median duration of response was not reached (95% CI, 16.7 to not estimable), and median progression-free survival was 14.2 months (95% CI, 8.3 to not estimable). Grade ≥3 adverse events (AEs; >5%) included anemia, pneumonia, and fatigue. Serious AEs of any grade occurred in 44%, with grade 3-4 pneumonia being the most common (8%). Rates of discontinuation and dose reductions due to AEs were 17% and 10%, respectively. Single-agent ibrutinib induced durable responses with a favorable benefit-risk profile in patients with previously treated MZL, confirming the role of BCR signaling in this malignancy. As the only approved therapy, ibrutinib provides a treatment option without chemotherapy for MZL.

Combination of Pim kinase inhibitor SGI-1776 and bendamustine in B-cell lymphoma.

PubMed

Yang, Qingshan; Chen, Lisa S; Neelapu, Sattva S; Gandhi, Varsha

2013-09-01

SGI-1776 is a small-molecule Pim kinase inhibitor that primarily targets c-MYC-driven transcription and cap-dependent translation in mantle cell lymphoma (MCL) cells. Bendamustine is an alkylating chemotherapeutic agent approved for use in B-cell lymphoma that is known to induce DNA damage and initiate response to repair. Our studies were conducted in MCL cell lines JeKo-1 and Mino, as well as primary B-cell lymphoma samples of MCL and splenic marginal zone lymphoma (SMZL), where we treated cells with SGI-1776 and bendamustine. We measured levels of cellular apoptosis, macromolecule synthesis inhibition, and DNA damage induced by drug treatments. Both SGI-1776 and bendamustine effectively induced apoptosis as single agents, and when used in combination, an additive effect in cell killing was observed in MCL cell lines JeKo-1 and Mino, as well as in MCL and SMZL primary cells. As expected, SGI-1776 was effective in inducing a decrease of global RNA and protein synthesis, and bendamustine significantly inhibited DNA synthesis and generated a DNA damage response. When used in combination, the effects were intensified in DNA, RNA, and protein synthesis inhibition compared with single-agent treatments. These data provide a foundation and suggest the feasibility of using Pim kinase inhibitors in combination with chemotherapeutic agents such as bendamustine in B-cell lymphoma.

We herein report a case of a 46-year-old woman with anaplastic lymphoma kinase (ALK)-rearranged stage IV lung adenocarcinoma who received the ALK inhibitor crizotinib as second-line therapy. On the 47th day following crizotinib initiation, a chest computed tomography scan revealed ground-glass opacities with a clinical manifestation of desaturation, although a partial response to treatment was detected. The diagnosis of crizotinib-induced interstitial lung disease (ILD) was confirmed, and crizotinib was discontinued, followed by the initiation of corticosteroid therapy. After improvement of ILD with corticosteroid therapy, alectinib was administered as salvage therapy, resulting in tumor shrinkage without any recurrence of ILD. To the best of our knowledge, this is the first report of successful alectinib treatment following crizotinib-induced ILD. Our results indicate that alectinib could be a promising alternative treatment option in patients with crizotinib-induced ILD. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Lymphomas with primary or secondary involvement of central nervous system (CNS) have poor prognosis despite specific treatment protocols which include whole brain radiotherapy and high-dose systemic and/or intrathecal chemotherapy. Toxicity of intrathecal liposomal cytarabine-based regimens collected between November 2006 and January 2012 was assessed retrospectively. Data from 120 adult lymphoma patients with, or at high risk of CNS involvement who received intrathecal liposomal cytarabine-based regimens at six Polish Lymphoma Research Group centres between November 2006 and January 2012 were assessed retrospectively. Patients were divided into three cohorts: A (high risk of CNS disease, n = 88), B (cerebrospinal fluid pleocytosis without neurological symptoms or pathological imaging findings, n = 7), and C (CNS disease/neurological involvement; n = 25). In all examined groups, toxicity of treatment was found to be acceptable (including the prophylactic setting). None of the patients in cohorts A or B who took intrathecal liposomal cytarabine 50 mg, repeated every 2-4 weeks (mean 3.8 doses) had experienced a CNS relapse at a median follow-up time of 3 years. Patients in cohort C had a 76 % overall neurological response rate (including a 40 % complete response rate) and median overall survival of 4.8 years. Regimens incorporating liposomal cytarabine seem to be safe and effective treatments for lymphomas with CNS involvement.

Plasmablastic lymphoma (PBL) is a rare and aggressive subtype of non-Hodgkin lymphoma that commonly occurs in human immunodeficiency virus (HIV)-positive individuals, and affects oral sites. Occasionally, it has been described in HIV-negative patients and involving non-oral sites. Pathologically, PBL is a high-grade B-cell lymphoma that displays the immunophenotype of a terminally differentiated B-lymphocyte with loss of B-cell markers (CD20) and expression of plasma-cell antigens. Epstein-Barr virus infection and MYC rearrangements are frequently observed. Treatment of PBL is challenging because of the lack of established treatment and poor outcomes, with median survival times shorter than one year. In this review, we discuss the clinical and epidemiologic spectrum of PBL as well as its distinct pathological features. Finally, we summarize the currently available approaches for the treatment of patients with PBL. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

This review discusses promising new approaches in classical Hodgkin's lymphoma that have been recently evaluated. There is a focus on the fluorodeoxyglucose PET scanning that is now considered crucial for staging and treatment evaluation, including interim evaluation after two cycles. An up-front treatment strategy is discussed, with the place of radiation therapy and the difficult choice of chemotherapy intensity emphasized. Indications for frail patients are also reviewed, particularly elderly or HIV-positive patients. Emerging data on the antibody drug conjugate brentuximab vedotin and its future potential in the transplantation framework for relapsed/refractory Hodgkin's lymphoma is also discussed.

Targeting B lymphoma with nanoparticles bearing glycan ligands of CD22.

CD22 is a member of the siglec (sialic acid-binding immunoglobulin-like lectin) family expressed on B cells that recognizes glycans of glycoproteins as ligands. Because siglecs exhibit restricted expression on one or a few leukocyte cell types, they have gained attention as attractive targets for cell-directed therapies. Several antibody-based therapies targeting CD22 (Siglec-2) are currently in clinical trials for the treatment of hairy cell leukemia and other B cell lymphomas. As an alternative to antibodies we have developed liposomal nanoparticles decorated with glycan ligands of CD22 that selectively target B cells. Because CD22 is an endocytic receptor, ligand-decorated liposomes are bound by CD22 and rapidly internalized by the cell. When loaded with a toxic cargo such as doxorubicin, they are efficacious in prolonging life in a Daudi B cell lymphoma model. These B cell targeted nanoparticles have been demonstrated to bind and kill malignant B cells from patients with hairy cell leukemia, marginal zone lymphoma and chronic lymphocytic leukemia. The results demonstrate the potential of using CD22 ligand-targeted liposomal nanoparticles as an alternative approach for the treatment of B cell malignancies.

Programmed cell death protein 1 (PD-1) blockade targeting the PD-1 immune checkpoint has demonstrated unprecedented clinical efficacy in the treatment of advanced cancers including hematologic malignancies. This article reviews the landscape of PD-1/programmed death-ligand 1 (PD-L1) expression and current PD-1 blockade immunotherapy trials in B-cell lymphomas. Most notably, in relapsed/refractory classical Hodgkin lymphoma, which frequently has increased PD-1 + tumor-infiltrating T cells, 9p24.1 genetic alteration, and high PD-L1 expression, anti-PD-1 monotherapy has demonstrated remarkable objective response rates (ORRs) of 65% to 87% and durable disease control in phase 1/2 clinical trials. The median duration of response was 16 months in a phase 2 trial. PD-1 blockade has also shown promise in a phase 1 trial of nivolumab in relapsed/refractory B-cell non-Hodgkin lymphomas, including follicular lymphoma, which often displays abundant PD-1 expression on intratumoral T cells, and diffuse large B-cell lymphoma, which variably expresses PD-1 and PD-L1. In primary mediastinal large B-cell lymphoma, which frequently has 9p24.1 alterations, the ORR was 35% in a phase 2 trial of pembrolizumab. In contrast, the ORR with pembrolizumab was 0% in relapsed chronic lymphocytic leukemia (CLL) and 44% in CLL with Richter transformation in a phase 2 trial. T cells from CLL patients have elevated PD-1 expression; CLL PD-1 + T cells can exhibit a pseudo-exhaustion or a replicative senescence phenotype. PD-1 expression was also found in marginal zone lymphoma but not in mantle cell lymphoma, although currently anti-PD-1 clinical trial data are not available. Mechanisms and predictive biomarkers for PD-1 blockade immunotherapy, treatment-related adverse events, hyperprogression, and combination therapies are discussed in the context of B-cell lymphomas. © 2018 by The American Society of Hematology.

Giant cell arteritis (GCA) is an immunologically mediated vasculitis of large and medium-sized vessels, typically affecting the cranial arteries and usually occurring in the elderly. GCA of the female genital tract is extremely rare with only 31 cases reported in the English literature. An 83-year-old white female with postmenopausal vaginal bleeding revealed an endometrial polyp on pelvic ultrasonography following which polypectomy and subsequently hysterectomy with bilateral salpingo-oophorectomy was done. Microscopy revealed a well-differentiated endometrioid adenocarcinoma. Interestingly, classic GCA involving numerous small to medium-sized arteries of the cervix, myometrium, bilateral fallopian tubes, and ovaries was also identified. Hematologic evaluation revealed marginal zone lymphoma with an exceptionally rare 20q deletion. Bilateral temporal artery biopsy was done subsequently, which exhibited GCA on microscopy. Corticosteroid was started that improved her polymyalgia rheumatica symptoms. The patient is on follow-up for 3 years and is doing well. To our knowledge, this is the first case of GCA of the female genital tract associated with a lymphoma and the second case of marginal zone lymphoma with the novel 20q deletion. © The Author(s) 2015.

Differentiation of chronic gastritis from marginal zone B-cell lymphoma (MZoL) of MALT type is often difficult for the pathologist. Diagnostic tools include CD20 stain to highlight lymphoepithelial lesions, Wotherspoon grading of the infiltrate, and clonality analysis of the B-cells. MZoL may partially transform into a diffuse, large B-cell lymphoma, which the authors have named blastic MZoL. Blastic MZoL may be present with or without small cell MZoL. Without this component, blastic MzoL, while being CD10-negative, is presently difficult to positively diagnose since specific immune markers are still lacking. Blastic MZoL has a very favourable outcome compared to conventional diffuse large B-cell lymphomas (DLBCL). Moreover, there are conventional DLBCL in the stomach, mostly in a setting of a secondary organ involvement. The biology of these gastric DLBCL is identical to their extragastric counterparts. This is also true for primary gastric Burkitt lymphoma and mucosal involvement in B-CLL or mantle cell lymphoma. Unfavourable outcomes are always observed for EBV-triggered lymphoproliferations in immunodeficiency and peripheral T-cell lymphomas which might also arise or be initially diagnosed in the stomach.

Infectious agents play a critical role in MALT lymphoma development. Studies from Italy showed Chlamydia psittaci infection in 87% of ocular adnexal MALT lymphomas and complete or partial regression of the lymphoma after C. psittaci eradication in four of nine cases. However, C. psittaci was not demonstrated in ocular adnexal MALT lymphomas from the USA. This study was thus designed to investigate further the role of C. psittaci, and other infectious agents commonly associated with chronic eye disease, in the development of ocular adnexal MALT lymphoma. The presence of C. psittaci, C. trachomatis, C. pneumoniae, herpes simplex virus 1 and 2 (HSV1, HSV2), and adenovirus 8 and 19 (ADV8, ADV19) was assessed separately by polymerase chain reaction in 142 ocular adnexal MALT lymphomas, 53 non-marginal zone lymphomas, and 51 ocular adnexal biopsies without a lymphoproliferative disorder (LPD), from six geographical regions. C. psittaci was detected at similar low frequencies in non-LPD and non-marginal zone lymphoma groups from different geographical regions (0-14%). Overall, the prevalence of C. psittaci was significantly higher in MALT lymphomas (22%) than in non-LPD (10%, p=0.042) and non-marginal zone lymphoma cases (9%, p=0.033). However, the prevalence of C. psittaci infection in MALT lymphoma showed marked variation among the six geographical regions examined, being most frequent in Germany (47%), followed by the East Coast of the USA (35%) and the Netherlands (29%), but relatively low in Italy (13%), the UK (12%), and Southern China (11%). No significant differences in the detection of C. pneumoniae, C. trachomatis, HSV1, HSV2, ADV8, and ADV19 were found between lymphomas and controls from different geographical regions. In conclusion, our results show that C. psittaci, but not C. pneumoniae, C. trachomatis, HSV1, HSV2, ADV8 or ADV19, is associated with ocular adnexal MALT lymphoma and that this association is variable in different geographical areas.

This study investigates the value of performing a staging bone marrow in patients with diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL) and classical hodgkin lymphoma (CHL). The results of 3112 staging bone marrow examinations were assessed for impact on prognostic assessment and critical treatment decisions. The detection of marrow involvement altered the disease-specific prognostic index for 4·3% of DLBCL, 6·2% of FL and 0·6% of CHL but marrow involvement in DLBCL was an independent prognostic factor. Knowing the marrow status potentially changed treatment in 92 patients, detection of these patients would have required 854 examinations to be performed. © 2015 John Wiley & Sons Ltd.

Survival rates have been excellent in patients treated for Hodgkin lymphoma (HL) during childhood and adolescence. Unfortunately, severe treatment related late effects have been observed. It was therefore an important aim of the cooperative pediatric HL therapy studies in Germany to reduce the number of late effects without jeopardizing the excellent treatment results. Progress and relapses of HL were analyzed to obtain important information for the future salvage therapy. All late effects were documented and their etiologies analyzed. Information obtained from bacterial infections and late deaths following splenectomy were used to inform patients at risk and their local physicians about necessary preventive measurements. Procarbazine was recognized as major gonadotoxic agent in boys and eliminated successively from the treatment regimens. Parenthood was normal in female patients when compared to the German female population documenting normal ovarian function except in patients with pelvic radiation. Radiation was the most important risk factor for thyroid diseases, cardiac late effects and subsequent malignant neoplasms, especially thyroid and breast cancer. A special screening program was initiated for women with chest radiotherapy, since they had a high risk of breast cancer already at a young age. The results of the HL Late Effects Research Project are important for the aftercare of patients and for the design of future HL treatment regimens. © Georg Thieme Verlag KG Stuttgart · New York.

Gray zone lymphoma (GZL) is described as sharing features with classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL). However, there remains complexity in establishing diagnosis, delineating prognosis, and determining optimum therapy. Sixty-eight cases diagnosed as GZL across 15 North American academic centers were evaluated by central pathology review to achieve consensus. Of these, only 26 (38%) were confirmed as GZL. Morphology was critical to GZL consensus diagnosis (eg, tumor cell richness); immunohistochemistry showed universal B-cell derivation, frequent CD30 expression, and rare Epstein-Barr virus (EBV) positivity (CD20 + , 83%; PAX5 + , 100%; BCL6 + , 20%; MUM1 + , 100%; CD30 + , 92%; EBV + , 4%). Forty-two cases were reclassified: nodular sclerosis (NS) cHL, n = 27 (including n = 10 NS grade 2); lymphocyte predominant HL, n = 4; DLBCL, n = 4; EBV + DLBCL, n = 3; primary mediastinal large BCL n = 2; lymphocyte-rich cHL and BCL-not otherwise specified, n = 1 each. GZL consensus-confirmed vs reclassified cases, respectively, more often had mediastinal disease (69% vs 41%; P = .038) and less likely more than 1 extranodal site (0% vs 25%; P = .019). With a 44-month median follow-up, 3-year progression-free survival (PFS) and overall survival for patients with confirmed GZL were 39% and 95%, respectively, vs 58% and 85%, respectively, for reclassified cases ( P = .19 and P = .15, respectively). Interestingly, NS grade 2 reclassified patients had similar PFS as GZL consensus-confirmed cases. For prognostication of GZL cases, hypoalbuminemia was a negative factor (3-year PFS, 12% vs 64%; P = .01), whereas frontline cyclophosphamide, doxorubicin, vincristine, and prednisone ± rituximab (CHOP±R) was associated with improved 3-year PFS (70% vs 20%; P = .03); both factors remained significant on multivariate analysis. Altogether, accurate diagnosis of GZL remains challenging, and improved therapeutic strategies are needed.

The mechanisms underlying the transformation from chronic Helicobacter pylori gastritis to gastric extranodal marginal zone lymphoma (MALT lymphoma) are poorly understood. This study aims to identify microRNAs that might be involved in the process of neoplastic transformation. We generated microRNA signatures by RT-PCR in 68 gastric biopsy samples representing normal mucosa, gastritis, suspicious lymphoid infiltrates, and overt MALT lymphoma according to Wotherspoon criteria. Analyses revealed a total of 41 microRNAs that were significantly upregulated (n = 33) or downregulated (n = 8) in succession from normal mucosa to gastritis and to MALT lymphoma. While some of these merely reflect the presence of lymphocytes (e.g. miR-566 and miR-212) or H. pylori infection (e.g. miR-155 and let7f), a distinct set of five microRNAs (miR-150, miR-550, miR-124a, miR-518b and miR-539) was shown to be differentially expressed in gastritis as opposed to MALT lymphoma. This differential expression might therefore indicate a central role of these microRNAs in the process of malignant transformation.

Doxorubicin-loaded platelets conjugated with anti-CD22 mAbs: a novel targeted delivery system for lymphoma treatment with cardiopulmonary avoidance

2017-01-01

B-cell lymphoma accounts for approximately 85% of all adult non-Hodgkin's lymphoma cases. Doxorubicin (DOX) is an indispensable drug for the treatment of non-Hodgkin's lymphoma. However, DOX causes severe cardiotoxicity, which limits its use in conventional treatment strategies. In this study, we developed a novel drug delivery system for lymphoma treatment: DOX-loaded platelets that were conjugated with anti-CD22 monoclonal antibodies (mAbs) (DOX–platelet–CD22). Platelets are bio- and immune-compatible drug carriers that can prolong the circulation time of drugs. Anti-CD22 mAb-labeled platelets can precisely deliver DOX to tumor cells. Our in vitro and in vivo experiments showed the enhanced antitumor activity and attenuated cardiotoxicity of DOX when delivered as DOX–platelet–CD22. Compared with other delivery systems, the uptake of DOX–platelet–CD22 by macrophage-like cells decreased. Moreover, DOX–platelet–CD22 showed platelet properties, such as tumor cell-induced platelet aggregation. Therefore, targeted chemotherapy that is mediated by DOX–platelet–CD22 is a promising option for lymphoma treatment. PMID:28938559

Nodular lymphocyte-predominant Hodgkin lymphoma: a unique disease deserving unique management.

PubMed

Eichenauer, Dennis A; Engert, Andreas

2017-12-08

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare lymphoma entity with an incidence of 0.1 to 0.2/100 000/y. Compared with the more common subtypes of classical Hodgkin lymphoma, NLPHL is characterized by distinct pathological and clinical features. Histologically, the disease-defining lymphocyte predominant cells consistently express CD20 but lack CD30. Clinically, NLPHL mostly has a rather indolent course, and patients usually are diagnosed in early stages. The prognosis of early-stage NLPHL is excellent, with progression-free survival and overall survival rates exceeding 90% after involved-field radiotherapy (IF-RT) alone (stage IA) or combined modality treatment consisting of a brief chemotherapy with 2 cycles of ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) chemotherapy followed by IF-RT (early stages other than stage IA). In contrast, patients with advanced disease at diagnosis tend to relapse either with NLPHL histology or with histological transformation into aggressive B-cell non-Hodgkin lymphoma despite more aggressive first-line treatment with 6 to 8 cycles of multiagent chemotherapy. However, even NLPHL patients with multiple relapses successfully respond to salvage therapy in many cases. Salvage therapies range from single-agent anti-CD20 antibody treatment to high-dose chemotherapy followed by autologous stem cell transplantation. Treatment at disease recurrence should be chosen on the basis of various factors, including histology at relapse, time to relapse, extent of disease at relapse, and prior treatment. Because death among NLPHL patients is more often caused by therapy-related late effects than lymphoma-related complications, optimizing the risk-benefit ratio of treatment by decreasing toxicity whenever possible is the major goal of clinical research in this disease. © 2016 by The American Society of Hematology.

Hodgkin lymphoma (HL) has become one of the best curable malignancies today. This is particularly true for patients with early-stage disease. Today, most patients in this risk group are treated with a combination of chemotherapy followed by small-field radiotherapy. More recent clinical trials such as the German Hodgkin Study Group (GHSG) HD10 study demonstrated, that even two cycles of ABVD followed by 20 Gy involved-field radiation therapy (IF-RT) are sufficient and result in more than 90% of patients being cured. The current treatment for early unfavorable patients is either four cycles of ABVD plus 30 Gy IF-RT or two cycles of BEACOPPbaseline followed by two cycles of ABVD plus IF-RT. Here, the European Organization for Research and Treatment of Cancer (EORTC) demonstrated that in positron emission tomography (PET)-positive patients after two cycles of ABVD, treatment switched to two cycles of BEACOPPbaseline plus radiotherapy results in significantly improved outcomes. Other aspects including attempts to further reduce intensity of treatment will be discussed. Copyright © 2016 Elsevier Inc. All rights reserved.

A 66-year-old patient was diagnosed with primary gastric B-cell lymphoma. The pathological findings were consistent with diffuse large B-cell lymphoma (DLBCL); however, a small area showed features of mucosa-associated lymphoid tissue (MALT) lymphoma. Biopsy specimens were referred to two other pathologists, both of whom diagnosed the case as pure DLBCL, denying the area of MALT lymphoma. As the lymphoma was limited to the submucosal layer and the patient's general condition was excellent, eradication of Helicobacter pylori was selected as the initial treatment. The lymphoma completely disappeared three months after the eradication treatment, and complete remission has been maintained for nearly two years.

Helicobacter pylori infection plays a central role in the development of gastric MALT-type (mucosa-associated lymphoid tissue) lymphoma. Infection results in chronic H. pylori gastritis and stimulates together with antigens or autoantigens proliferation of B-lymphocytes which is the basis for the neoplastic transformation. Histology of MALT-type lymphoma is architecturally similar to the physiological MALT. Invasion and destruction of the gastric epithelium with development of so-called lympho-epithelial lesions is the most important diagnostic criterion. Cytologically MALT-lymphoma resembles centrocytes and monocytes. For definitive lymphoma diagnosis and for the differential diagnosis from other small cell lymphomas in the stomach immunohistochemistry can be helpful. The phenotype of MALT-type lymphoma is identical to non-neoplastic B-lymphocytes of the marginal zone (CD20+, CD5-, CD10- and CD23-). Individual therapy is strongly dependent from histological type and lymphoma stadium. Therapy modalities are H. pylori eradication, radiochemotherapy, surgery or a combination of these. Aim of the therapy is the complete lymphoma regression and cure of the disease.

Several studies have suggested an increased risk of malignant tumor in patients with rheumatoid arthritis. It has been also reported that rheumatoid arthritis patients have a high incidence of lymphoma compared with the general population, and that patients receiving methotrexate, which is the anchor drug for rheumatoid arthritis treatment, can develop lymphoproliferative disease. Nevertheless, management of rheumatoid arthritis after treatment for methotrexate-associated lymphoma has not been fully investigated. We here report a patient with rheumatoid arthritis who developed malignant lymphoma associated with methotrexate therapy. Moreover, we describe the use of a biologic agent for a rheumatoid arthritis patient after treatment for lymphoma associated with methotrexate. A 60-year-old Japanese man with a 20-year history of rheumatoid arthritis was admitted to our hospital with a left inguinal tumor. Open biopsy was performed and a biopsy specimen revealed diffuse large B-cell lymphoma. As our patient had received methotrexate for 4 years, we diagnosed the lymphoproliferative disease as being methotrexate-related. This lymphoma was not associated with Epstein- Barr virus by Epstein-Barr virus-encoded ribonucleic acid in-situ hybridization, but this patient was an Epstein-Barr virus carrier, regarding serological testing. The lymphoma went into complete remission after 6 courses of rituximab plus cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisone/prednisolone therapy. Two years later, however, rheumatoid arthritis activity gradually increased and was not controlled with salazosulfapyridine. Etanercept was administered in view of its possible effect on B-cells, and this reduced the level of disease activity without recurrence of lymphoma. The management of rheumatoid arthritis after treatment for methotrexate-associated lymphoma has not been fully investigated yet. Etanercept appeared to be safe because of its B-cell effect, but further observation

Primary cutaneous lymphomas are a heterogeneous group of diseases. They often remain localized, and they generally have a more indolent course and a better prognosis than lymphomas in other locations. They are highly radiosensitive, and radiation therapy is an important part of the treatment, either as the sole treatment or as part of a multimodality approach. Radiation therapy of primary cutaneous lymphomas requires the use of special techniques that form the focus of these guidelines. The International Lymphoma Radiation Oncology Group has developed these guidelines after multinational meetings and analysis of available evidence. The guidelines represent an agreed consensus view of the International Lymphoma Radiation Oncology Group steering committee on the use of radiation therapy in primary cutaneous lymphomas in the modern era.

Primary gastric low-grade B-cell lymphomas are neoplastic mimics of mucosa associated lymphoid tissue (MALT) as exemplified by Peyer's patches in the terminal ileum. Architectural and immunophenotypic properties of the neoplastic cells suggest that they originate from MALT-derived marginal zone B-cells. Paradoxically, the normal human stomach is devoid of organized MALT within which a lymphoma can develop. Lymphoid tissue is acquired in the stomach in response to antigenic stimulation, predominantly associated with Helicobacter pylori infection. Studies of patients with low-grade MALT lymphoma have confirmed a high incidence of H. pylori infection and suggest that the infection predates neoplastic transformation. Certain morphological features of MALT lymphomas suggest that the tumor cells remain responsive to antigen drive. Given the close association between gastric MALT lymphoma and H. pylori, it is possible that this organism provides such a drive. In vitro studies have shown that the tumor cells proliferate in a T-cell-dependent way to the presence of H. pylori. Several studies have now demonstrated that eradication of the organism in patients with low-grade gastric MALT lymphoma can result in regression of the tumor. In cases with a high-grade component, the associated low-grade part may regress, but most high-grade gastric MALT lymphomas are unresponsive to this conservative therapy.

Lymphoma is a common malignancy observed in companion animals. This type of naturally occurring neoplasia has been uncommonly reported in great apes. Diffuse large B-cell lymphoma was diagnosed in an 8-yr-old captive orangutan (Pongo pygmaeus) with gastrointestinal disease by histologic and immunohistochemical methodologies. The orangutan was treated with three cycles of combination chemotherapy (intravenous Rituxan, cyclophosphamide, doxorubicin, and vincristine). The primate has been in good health and exhibiting normal behaviors for more than 15 mo following treatment.

The treatment of the germinal center lymphomas, diffuse large B cell (DLBCL) and follicular lymphoma, has changed little beyond the introduction of immunochemotherapies. However, there exists a substantial group of patients within both diseases for which improvements in care will involve appropriate tailoring of treatment. DLBCL consists of two major subtypes with striking differences in their clinical outcomes paralleling their underlying genetic heterogeneity. Recent studies have seen advances in the stratification of germinal center lymphomas, through comprehensive profiling of 1001 DLBCLs alongside refinements in the identification of high-risk follicular lymphoma patients using m7-FLIPI and 23G models. A new wave of novel therapeutic agents is now undergoing clinical trials for germinal center lymphomas, with BCR and EZH2 inhibitors demonstrating preferential benefit in subgroups of patients. The emergence of cell-free DNA has raised the possibility of dynamic disease monitoring to potentially mitigate the complexity of spatial and temporal heterogeneity, whilst predicting tumor evolution in real time. Altogether knowledge of the genomic landscape of germinal center lymphomas is offering welcome opportunities in patient risk stratification and therapeutics. The challenge ahead is to establish how best to combine upfront or dynamic prognostication with precision therapies, while retaining practicality in clinical trials and the real-world setting.

In the past decade, a notable advance has been made in the understanding of the pathogenesis of NK/T-cell lymphomas; however, their diagnosis remains difficult because of their rarity and clinical and morphological variabilities. The paper generalizes the ten-year experience of the Hematology Research Center, Ministry of Health of Russia, in diagnosing and treating hepatosplenic T-cell lymphoma (HSTL), considers the problems of differential diagnosis with other hematological diseases occurring with similar clinical and laboratory symptoms, and lays down current approaches to the diagnosis and treatment of this condition. A clinician's view of the problem of diagnosis and treatment of this disease is given. HSTL is shown to be a heterogeneous group of diseases differing in a T-cell receptor chain gene rearrangement, the clinical course of the disease, and overall survival (OS). According to our data, 3-year OS was 12%; the median survival was 26 months. Two-year OS for γδ and αβ HSTL was equal to 25 and 70%, respectively. The difference in OS for the variants of HSTL failed to reach statistical significance (because the sample might be insufficient).

Combination of Pim kinase inhibitor, SGI-1776, with bendamustine in B-cell lymphoma

PubMed Central

2013-01-01

SGI-1776 is a small molecule Pim kinase inhibitor that primarily targets c-Myc-driven transcription and cap-dependent translation in mantle cell lymphoma (MCL) cells. Bendamustine is an alkylating chemotherapeutic agent approved for use in B-cell lymphoma that is known to induce DNA damage and to initiate response to repair. We hypothesized that while each drug leads to the effects as stated above, combination of these drugs will enhance SGI-1776-induced inhibition of global transcription and translation processes, while promoting bendamustine-triggered decrease of DNA synthesis and DNA damage response in B-cell lymphoma. Both SGI-1776 and bendamustine as single agents effectively induced apoptosis and when used in combination, additive effect in cell killing was observed in MCL cell lines, JeKo-1 and Mino, as well as MCL and splenic marginal zone lymphoma (a type of B-cell lymphoma) primary cells. As expected, SGI-1776 was effective in inducing decrease of global RNA and protein synthesis, while bendamustine significantly inhibited DNA synthesis and generated DNA damage response. When used in combination, effects were intensified in DNA, RNA and protein syntheses compared to single agent treatments. Together, these data provided foundation and suggested feasibility of using Pim kinase inhibitor in combination with chemotherapeutic agents such as bendamustine in B-cell lymphoma. PMID:24290221

Lymphoma of the Urinary Bladder

Venyo, Anthony Kodzo-Grey

2014-01-01

Background. Lymphoma of the urinary bladder (LUB) is rare. Aims. To review the literature on LUB. Methods. Various internet databases were used. Results. LUB can be either primary or secondary. The tumour has female predominance; most cases occur in middle-age women. Secondary LUB occurs in 10% to 25% of leukemias/lymphomas and in advanced-stage systemic lymphoma. Less than 100 cases have been reported. MALT typically affects adults older than 60 years; 75% are female. Diffuse large B-cell lymphoma is also common and may arise from transformation of MALT. LUB presents with haematuria, dysuria, urinary frequency, nocturia, and abdominal or back pain. Macroscopic examination of LUBs show large discrete tumours centred in the dome or lateral walls of the bladder. Positive staining of LUB varies by the subtype of lymphoma; B-cell lymphomas are CD20 positive. MALT lymphoma is positively stained for CD20, CD19, and FMC7 and negatively stained for CD5, CD10, and CD11c. LUB stains negatively with Pan-keratin, vimentin, CK20, and CK7. MALT lymphoma exhibits t(11; 18)(q21: 21). Radiotherapy is an effective treatment for the MALT type of LUB with no recurrence. Conclusions. LUB is diagnosed by its characteristic morphology and immunohistochemical characteristics. Radiotherapy is a useful treatment. PMID:24511310

Helicobacter pylori infection in gastric mucosa-associated lymphoid tissue lymphoma

Gastrointestinal lymphoma is the most common type of extranodal lymphoma, and most commonly affects the stomach. Marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) and diffuse large B-cell lymphoma are the most common histologic types of gastric lymphoma. Despite its increasing incidence, diagnosis of gastric lymphoma is difficult at an earlier stage due to its nonspecific symptoms and endoscopic findings, and, thus, a high index of suspicion, and multiple, deep, repeated biopsies at abnormally and normally appearing sites in the stomach are needed. In addition, testing for Helicobacter pylori (H. pylori) infection and endoscopic ultrasonography to determine the depth of tumor invasion and involvement of regional lymph nodes is essential for predicting response to H. pylori eradication and for assessment of disease progression. In addition, H. pylori infection and MALT lymphoma development are associated, and complete regression of low-grade MALT lymphomas after H. pylori eradication has been demonstrated. Radiotherapy and/or chemotherapy can be used in cases that show poor response to H. pylori eradication, negativity for H. pylori infection, or high-grade lymphoma. PMID:24659867

We report the first case to our knowledge of a patient with relapsed/refractory classical hodgkin lymphoma and liver failure with encephalopathy along with human immunodeficiency virus/acquired immunodeficiency syndrome infection, successfully treated with nivolumab without major side effects and encouraging prolonged disease control. In December 2015, at the time of the patient's progression from his Hodgkin lymphoma after fourth line treatment, he developed persistent fevers, abdominal distension, jaundice and worsening of his liver function tests. Magnetic resonance imaging of abdomen/pelvis demonstrated hepatomegaly with innumerable new liver lesions, splenomegaly with multiple splenic nodules and several new mediastinal, intraperitoneal and retroperitoneal lymphadenopathy. In accordance with the patient's wishes before admission, and after agreement with the family, nivolumab (3 mg/kg every 2 weeks) was given. Of note, antiretroviral therapy was on hold due to liver function tests, his viral load was undectable and cluster of differentiation 4 counts were 103/uL at the time of nivolumab administration. One week after the first dose of nivolumab both his hepatic encephalopathy and constitutional symptoms started to improve, and after 2 doses, (January 2016) his LFTs were almost back to normal. After 5 months of nivolumab treatment (10 doses), restaging (computerized tomography scans of neck, chest, abdomen, pelvis) done on May 2016 showed resolution of hepatosplenomegaly with two residual small hepatic lesions, heterogeneous spleen with no splenic lesions, and stable non-enlarged retroperitoneal lymph nodes without intraabdominal lymphadenopathy; consistent with partial response. We report a case of a patient with human immunodeficiency virus/acquired immunodeficiency syndrome -related relapsed/refractory classical Hodgkin lymphoma and acute liver failure with encephalopathy successfully treated with nivolumab after failing all standard therapeutic options

In this study, we aimed to determine the perspectives of medical and radiation oncologists regarding consolidation radiotherapy in patients with a complete response after chemotherapy for Hodgkin’s and non-Hodgkin’s lymphomas. The survey was designed to identify demographic and occupational features of medical and radiation oncologists and their views on application of consolidation radiotherapy in their clinical practices, as based on a five-point Likert scale (never, rarely, sometimes, often, and always). The study covered 263, out of 935, physicians working in the oncology field as either medical or radiation oncologists; the rate of return on the invitations to participate was 28%. The majority of the participants were male radiation oncologists, with a duration of between 5 and 10 years of work as a university hospital official, and the mean age was 38 ± 14 (years). Although the most commonly followed international guidelines were NCCN, among the physicians, the majority of the respondents suggested that the guidelines were unclear regarding recommendations for consolidative radiotherapy. The administered dose for consolidative radiotherapy in lymphoma patients was indicated as 40 Gy by 49% of all the physicians and the most common cause of hesitancy concerning consolidative radiation treatment was the risk of secondary malignancies as a long-term adverse effect (54%). In conclusion, we suggest that medical oncologists could be most active in the treatment of lymphoma through a continuous training program about lymphomas and current national guidelines.

Purpose: To review the treatment and outcomes of patients with primary cutaneous B-cell lymphoma (CBCL). Methods and Materials: Clinical characteristics, treatment, and outcomes were analyzed for all patients referred to our institution from 1981 through 2011 with primary CBCL without extracutaneous or distant nodal spread at diagnosis (n=136). Hematopathologists classified 99% of cases using the World Health Organization-European Organization for Research and Treatment of Cancer (WHO-EORTC) guidelines. Results: Median age at diagnosis was 62 years. Classification was 18% diffuse large B-cell leg-type (DLBCL-leg), 32% follicle center (FCCL), 45% marginal zone (MZL), and 6% nonclassifiable (OTHER). Of the 111 subjects withmore » indolent lymphoma (FCCL, MZL, OTHER), 79% received radiation alone (RT), 11% surgery alone, 3% chemotherapy alone, 4% chemotherapy followed by RT, and 3% observation. Following treatment, 29% of subjects relapsed. In-field recurrence occurred in 2% treated with RT and in 33% treated with surgery alone. Of the 25 subjects with DLBCL-leg, 52% received chemotherapy followed by RT, 24% chemotherapy, 20% RT, and 4% surgery alone. Seventy-nine percent received CHOP-type chemotherapy (cyclophosphamide, doxorubicin or epirubicin, vincristine, prednisone), 47% with rituximab added. Overall and disease-specific survival and time to progression at 5 years were 81%, 92%, and 69% for indolent and 26%, 61%, and 54% for DLBCL-leg, respectively. On Cox regression analysis of indolent subjects, RT was associated with better time to progression (P=.05). RT dose, chemo, age >60 y, and >1 lesion were not significantly associated with time to progression. For DLBCL-leg, disease-specific survival at 5 years was 100% for those receiving rituximab versus 67% for no rituximab (P=.13). Conclusions: This review demonstrates better outcomes for indolent histology compared with DLBCL-leg, validating the prognostic utility of the WHO-EORTC classification. In the

Angiocentric lymphoma, known as natural killer (NK)/T-cell non-Hodgkin's lymphoma, has been reported to be associated with the Epstein-Barr virus (EBV). We performed adoptive transfer of EBV-specific polyclonal T-cell lines in 3 patients with extranodal NK/T-cell lymphoma, nasal type, and evaluated the treatment for safety, immunologic reconstitution, and clinical outcomes. The tissue samples collected from the 3 patients were confirmed by polymerase chain reaction analysis to be EBV positive. In the cases of the first and second patients, EBV-transformed B-lymphoblastoid cell lines (LCLs) and T-cell lines were generated from peripheral lymphocytes of HLA-matched sibling donors. The third patient's T-cell lines were induced with autologous lymphocytes. Polyclonal T-cell infusion was carried out after high-dose radiotherapy because active relapsed disease remained in all of the patients. The first patient received 4 weekly infusions of 2 3 10(7) cells/m(2), and the second and third patients underwent treatment with 2 cycles of infusions of the same dosage. All T-cell lines showed >60% NK activity, cytotoxic T-lymphocyte (CTL) responses of >40% against autologous LCLs, and no CTL activity against patient-derived lymphoblasts. The level of cytotoxicity increased substantially in all patients after cell infusion. The 2 patients who received T-cell therapy twice had stabilized disease for more than 3 years. These safe treatments exhibited no severe inflammatory response, and no serious toxicity developed during T-cell therapy. Our findings demonstrate that adoptively transferred cells may provide reconstitution of EBV-specific CTL responses in patients with active relapsed angiocentric lymphoma. These results provide a rationale for the immunotherapy of angiocentric lymphoma.

Protein kinase inhibitors against malignant lymphoma

Introduction Tyrosine kinases (TKs) are intimately involved in multiple signal transduction pathways regulating survival, activation, proliferation and differentiation of lymphoid cells. Deregulation or overexpression of specific oncogenic TKs is implicated in maintaining the malignant phenotype in B-lineage lymphoid malignancies. Several novel targeted TK inhibitors (TKIs) have recently emerged as active in the treatment of relapsed or refractory B-cell lymphomas that inhibit critical signaling pathways, promote apoptotic mechanisms or modulate the tumor microenvironment. Areas covered In this review, the authors summarize the clinical outcomes of newer TKIs in various B-cell lymphomas from published and ongoing clinical studies and abstracts from major cancer and hematology conferences. Expert opinion Multiple clinical trials have demonstrated that robust antitumor activity can be obtained with TKIs directed toward specific oncogenic TKs that are genetically deregulated in various subtypes of B-cell lymphomas. Clinical success of targeting TKIs is dependent upon on identifying reliable molecular and clinical markers associated with select cohorts of patients. Further understanding of the signaling pathways should stimulate the identification of novel molecular targets and expand the development of new therapeutic options and individualized therapies.

Eighty-eight dogs with relapsed lymphoma were treated with the MOMP (mechlorethamine, vincristine, melphalan and prednisone) protocol on a 28-day treatment cycle. The overall response rate (ORR) to the MOMP protocol was 51.1% for a median of 56 days (range 7-858 days). Twelve percent of dogs experienced a complete response for a median of 81 days (range 42-274 days) and 38.6% experienced a partial response for a median of 49 days (range 7-858 days). Dogs with T-cell lymphoma had an ORR of 55% for a median of 60 days (range 49-858 days) while those with B-cell lymphoma had an ORR of 57% for a median of 81 days (range 7-274 days) (P = 0.783). The overall survival time for all dogs was 183 days (range 17-974 days). Fifty-four percent of dogs experienced toxicity with the majority classified as grade I. The MOMP protocol seems well-tolerated and is an option for dogs with relapsed lymphoma. © 2013 John Wiley & Sons Ltd.

A three-year-old male African hedgehog was presented for a non healing crusty proliferation on the left pinna. The lesion failed to respond to topical therapy and systemic antibiotic therapy. Whole body radiography and abdominal ultrasonograpy were within normal limits. The lesion was surgically removed. The patient recovered well from the procedure and remained in remission for nine months when he came back as an emergency case and died of an unrelated disease. The histopathology report enabled a diagnosis of completely excised cutaneous T-cell lymphoma. This report represents the first successful treatment of a cutanous T-cell lymphoma in this species and might help to plan future therapies.

Paediatric and adolescent elevated conjunctival lesions in the plical area: lymphoma or reactive lymphoid hyperplasia?

2014-05-01

To report clinical, histopathological and molecular features of 'salmon patch'-like conjunctival lesions in paediatric and adolescent patients, and discuss management of these patients and outcome. Patients who presented between 2000 and 2011 with a conjunctival 'salmon-patch'-like lesion in the plical area, were identified by chart review. Clinical parameters, demographic characteristics and details of ophthalmic imaging were collected, and the effect of treatment examined. Eleven patients aged 6-21 years, presented with an elevated pink conjunctival mass in the plical area of one or both eyes. Nine patients underwent an excisional biopsy that histopathologically disclosed extranodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (also termed 'MALT lymphoma') in two cases and reactive lymphoid hyperplasia (RLH) in seven cases. Molecular diagnosis showed polyclonal B cells in six patients, monoclonal B cells in two patients, and a questionable status in one patient. Systemic examination disclosed localised ocular adnexal disease in the patients with MALT lymphoma, and none had either local or systemic recurrence during follow-up. Two other patients were treated with antiallergic medication with resolution of the lesion, and were therefore diagnosed clinically with RLH. It is clinically difficult to differentiate between conjunctival RLH and MALT lymphoma in the paediatric and adolescent population. Both lesions are rare in this age group, particularly MALT lymphoma. Molecular analysis of excised lesions does not always correlate with histopathology. A short treatment course with antiallergic drops may sometimes assist diagnosis without compromising the patients due to the indolent nature of lymphoma in that area.

E2A-positive gastric MALT lymphoma has weaker plasmacytoid infiltrates and stronger expression of the memory B-cell-associated miR-223: possible correlation with stage and treatment response.

PubMed

2010-11-01

Extranodal marginal-zone lymphoma of mucosa-associated lymphoid tissue of the stomach (gastric MALT lymphoma) is derived from memory B cells of the marginal zone. Normal memory B cells do not express markers of germinal-center B cells, such as E2A (immunoglobulin enhancer-binding factor E12/E47), B-cell chronic lymphocytic leukemia/lymphoma 6 (BCL6), or activation-induced cytidine deaminase (AID). E2A is a transcription factor that induces somatic hypermutations and blocks plasma cell differentiation. In 50 stage-I(E)/II(E1) gastric MALT lymphomas, we confirmed that all cases were BCL6(-)/AID(-), but a subset (50%, 25/50) was E2A(+). As E2A(-) and E2A(+) gastric MALT lymphomas had similar numbers of somatic hypermutations without intraclonal variations, which implied an origin from memory B cells, the expression of E2A was best regarded as a marker of aberrant follicular differentiation. Although the status of somatic hypermutation was not affected by E2A, E2A(+) gastric MALT lymphoma showed less plasmacytoid infiltrates and higher expressions of miRNA-223, a microRNA associated with memory B cells. Clinically, E2A(+) gastric MALT lymphomas were more likely to spread to perigastric lymph nodes and were less responsive to Helicobacter eradication therapy than were E2A(-) gastric MALT lymphomas. Taken together, aberrant E2A expression is a diagnostic feature of a subtype of gastric MALT lymphoma with weaker plasmacytoid infiltrates and stronger miR-223 expression. A prospective study would be necessary to verify the association between E2A expression and a poor response to Helicobacter eradication therapy.

Successful use of full-dose dexamethasone, high-dose cytarabine, and cisplatin as part of initial therapy in non-hodgkin and hodgkin lymphoma with severe hepatic dysfunction.

2009-04-01

Anthracycline-based chemotherapy is the cornerstone of modern curative regimens for aggressive lymphomas; however, these drugs cannot be safely administered in the setting of severe hepatic dysfunction. Alternative regimens for this setting are required. We describe 2 patients with newly diagnosed advanced aggressive lymphoma (diffuse large B-cell lymphoma [DLBCL] and classic Hodgkin lymphoma [HL]) presenting with severe hepatic dysfunction with hyperbilirubinemia (4.3-13.2 mg/dL). Because of the inability to safely administer unattenuated doses of anthracycline-based regimens, dexamethasone, high-dose cytarabine, and cisplatin (DHAP) was used at full doses (along with rituximab for the DLBCL patient) until hepatic function normalized (1-5 cycles). The treatment was then converted to R-CHOP (rituximab/cyclophosphamide/ doxorubicin/vincristine/prednisone) and ABVD (doxorubicin/bleomycin/vinblastine/dacarbazine) for the DLBCL and HL patient, respectively, to complete therapy. The patients had a partial remission and complete remission, respectively. These data suggest that DHAP is a safe and effective regimen that can be used without dose modification as part of initial therapy in the setting of aggressive lymphoma and hepatic failure. The literature on the use of treatment regimens for aggressive lymphoma in the setting of hepatic dysfunction is reviewed.

Coccidioidomycosis, immunoglobulin deficiency: safety challenges with CAR T cells therapy for relapsed lymphoma.

Treatment of patients with relapsed or refractory lymphoma may require allogenic hematopoietic stem cell transplant (HSCT), but treatment of post-transplant relapse disease remains very challenging. Donor lymphocyte infusion and blinatumomab have been used with limited success for the treatment of relapse. Initial data on donor-derived CAR T cells has shown this modality to be safe and highly effective in various hematological malignancies. We present a case of a patient with highly refractory, transformed follicular lymphoma who failed both autologous and allogenic HSCT. Patient achieved long-lasting complete remission with the use of donor origin CD19 CAR T-cell therapy, without any evidence of graft-versus-host disease flare. Our patient later developed disseminated coccidioidomycosis and persistent hypogammaglobulinemia. Immunotherapy using CD19 CAR T cells can be a highly effective salvage modality, especially in cases of focal lymphoma relapse. Long-term immunosuppression secondary to B cell lymphopenia, hypogammaglobulinemia, immunoglobulin subclass deficiency, fungal infections and other infectious complications need to be monitored and promptly treated as indicated.

Endoscopic diagnosis of stomach mucosa-associated lymphoid tissue (MALT) lymphoma is often difficult because few specific findings are indicated. Even when MALT lymphoma is suspected by endoscopy, it is still difficult to make a definitive diagnosis by biopsy because lymphoma cells sometimes distribute unevenly. We previously reported that a tree-like appearance (TLA) is a characteristic finding of MALT lymphoma by narrow-band imaging (NBI) magnifying endoscopy and it is valuable in the selection of an optimal biopsy site in MALT lymphoma. Here, we study the frequency of TLA and evaluate the relationship between the response to eradication therapy and TLA in MALT lymphoma. We retrospectively examined the clinical background, endoscopic findings, response to eradication therapy, and Helicobacter pylori infection status of 16 patients diagnosed with MALT lymphoma who were referred to our hospital from April 2007 to August 2012. The regimen for eradicationtherapy consisted of rabeprazole, with amoxicillin and clarithromycin, all given for 7 days. TLA was found in 75% (12/16) and H. pylori infection in 75% (12/16) of patients diagnosed with MALT lymphoma by NBI magnifying endoscopy. In all complete regression (CR) patients after eradication treatment, the TLA finding had disappeared (100%); however, in the non-CR patients, TLA remained the same as before the eradication therapy (P=0.002). These results suggest that NBI magnifying endoscopy may be useful not only in the diagnosis but also in the evaluation of the response to eradication therapy of MALT lymphoma of the stomach. © 2013 The Authors.

Abstract Sarcoidosis is a granulomatous disease that most frequently affects the lungs with pulmonary infiltrates and/or bilateral hilar and mediastinal lymphadenopathy. An association of sarcoidosis and lymphoproliferative disease has previously been reported as the sarcoidosis-lymphoma syndrome. Although this syndrome is characterized by sarcoidosis preceding lymphoma, very few cases of sarcoidosis following lymphoma have been reported. We describe the clinical, biological, and radiological characteristics and outcome of 39 patients presenting with sarcoidosis following lymphoproliferative disease, including 14 previously unreported cases and 25 additional patients, after performing a literature review. Hodgkin lymphoma and non-Hodgkin lymphoma were equally represented. The median delay between lymphoma and sarcoidosis was 18 months. Only 16 patients (41%) required treatment. Sarcoidosis was of mild intensity or self-healing in most cases, and overall clinical response to sarcoidosis was excellent with complete clinical response in 91% of patients. Sarcoidosis was identified after a follow-up computerized tomography scan (CT-scan) or 18fluorodeoxyglucose-positron emission tomography/computerized tomography (18FDG-PET/CT) evaluation in 18/34 patients (53%). Sarcoidosis is therefore a differential diagnosis to consider when lymphoma relapse is suspected on a CT-scan or 18FDG-PET/CT, emphasizing the necessity to rely on histological confirmation of lymphoma relapse.

Both the BTK inhibitor ibrutinib and the BCL2 inhibitor venetoclax are active as monotherapy in the treatment of mantle-cell lymphoma. Complete response rates of 21% have been observed for each agent when administered as long-term continuous therapy. Preclinical models predict synergy in combination. We conducted a single-group, phase 2 study of daily oral ibrutinib and venetoclax in patients, as compared with historical controls. Patients commenced ibrutinib monotherapy at a dose of 560 mg per day. After 4 weeks, venetoclax was added in stepwise, weekly increasing doses to 400 mg per day. Both drugs were continued until progression or an unacceptable level of adverse events. The primary end point was the rate of complete response at week 16. Minimal residual disease (MRD) was assessed by flow cytometry in bone marrow and by allele-specific oligonucleotide-polymerase chain reaction (ASO-PCR) in blood. The study included 24 patients with relapsed or refractory mantle-cell lymphoma (23 patients) or previously untreated mantle-cell lymphoma (1 patient). Patients were 47 to 81 years of age, and the number of previous treatments ranged from none to six. Half the patients had aberrations of TP53, and 75% had a high-risk prognostic score. The complete response rate according to computed tomography at week 16 was 42%, which was higher than the historical result of 9% at this time point with ibrutinib monotherapy (P<0.001). The rate of complete response as assessed by positron-emission tomography was 62% at week 16 and 71% overall. MRD clearance was confirmed by flow cytometry in 67% of the patients and by ASO-PCR in 38%. In a time-to-event analysis, 78% of the patients with a response were estimated to have an ongoing response at 15 months. The tumor lysis syndrome occurred in 2 patients. Common side effects were generally low grade and included diarrhea (in 83% of the patients), fatigue (in 75%), and nausea or vomiting (in 71%). In this study involving historical controls

The incorporation of rituximab in immunochemotherapy has improved treatment outcomes for diffuse large B-cell lymphoma, but the prognosis for some diffuse large B-cell lymphomas remains dismal. Identification of adverse prognostic subgroups is essential for the choice of appropriate therapeutic strategy. We retrospectively investigated the impact of so-called 'double-hit' cytogenetic abnormalities, i.e. cytogenetic abnormalities involving c-MYC co-existing with other poor prognostic cytogenetic abnormalities involving BCL2, BCL6 or BACH2, on treatment outcomes for 93 consecutive diffuse large B-cell lymphoma patients. According to the revised international prognostic index, no patients were cytogenetically diagnosed with double-hit lymphomas in the 'very good' risk group or in the 'good' risk group, while 5 of 33 patients had double-hit lymphomas in the 'poor' risk group. All the double-hit lymphoma patients possessed both nodal and extranodal involvement. The overall complete response rate was 89.3%, overall survival 87.1% and progression-free survival 75.8% over 2 years (median observation period: 644 days). The complete response rates were 93.2% for the non-double-hit lymphoma patients and 40.0% for the double-hit lymphoma patients. Significantly longer progression-free survival and overall survival were observed for the 'very good' and the 'good' risk patients than for the 'poor' risk patients. Moreover, the progression-free survival of double-hit lymphoma was significantly shorter than that of the non-double-hit lymphoma 'poor' risk patients (P = 0.016). In addition, the overall survival of the double-hit lymphoma patients also tended to be shorter than that of the non-double-hit lymphoma 'poor' risk group. The diagnosis of double-hit lymphoma can help discriminate a subgroup of highly aggressive diffuse large B-cell lymphomas and indicate the need for the development of novel therapeutic strategies for double-hit lymphoma.

A 36-year-old Japanese woman presented with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) in the stomach. The gastric lesions only partially improved after eradication therapy for Helicobacter pylori. A fluorescence in situ hybridization analysis revealed no fusion genes of API2-MALT1, although trisomy of chromosome 18 was identified. Radiation therapy was initiated to treat the gastric lymphoma lesions, resulting in complete remission. However, MALT lymphoma recurred in the stomach 16 months later. This case indicates that intensive follow-up is required for MALT lymphoma associated with chromosomal aberrations in order to detect early relapse.

The World Health Organization classification of non-Hodgkin lymphoma (NHL) was introduced in 2001. However, its incorporation into clinical practice is not well-described. We studied the distribution of NHL subtypes in adults diagnosed from 1998 to 2011, evaluated time trends, geo-demographic correlates, and changes in 5-year overall survival (OS). We obtained data prospectively collected by the National Cancer Data Base, which covers 70% of US cancer cases. There were 596,476 patients diagnosed with NHL. The major subtypes were diffuse large B-cell (32.5%), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL; 18.6%), follicular (17.1%), marginal zone (8.3%), mantle cell (4.1%), peripheral T-cell not-otherwise-specified (1.7%), Burkitt (1.6%), hairy cell (1.1%), lymphoplasmacytic (1.1%), and NHL not-otherwise-specified (10.8%). Over the study period, the proportion of NHL not-otherwise-specified declined by half, while marginal zone lymphoma doubled. The distribution of major and rare NHL subtypes varied according to demographics but less so geographically or by type of treatment facility. We noted several novel findings among Hispanics (lower proportion of CLL/SLL, but higher Burkitt lymphoma and nasal NK/T-cell lymphoma), Asians (higher enteropathy-associated T-cell and angioimmunoblastic T-cell lymphomas), Blacks (higher hepatosplenic T-cell lymphoma), and Native Americans (similar proportions of CLL/SLL and nasal NK/T-cell lymphoma as Asians). With the exception of peripheral T-cell not-otherwise-specified and hairy cell leukemia, 5-year OS has improved for all the major NHL subtypes. © 2015 Wiley Periodicals, Inc.

How I treat double-hit lymphoma.

PubMed

Friedberg, Jonathan W

2017-08-03

The 2016 revision of the World Health Organization (WHO) classification for lymphoma has included a new category of lymphoma, separate from diffuse large B-cell lymphoma, termed high-grade B-cell lymphoma with translocations involving myc and bcl-2 or bcl-6 . These lymphomas, which occur in <10% of cases of diffuse large B-cell lymphoma, have been referred to as double-hit lymphomas (or triple-hit lymphomas if all 3 rearrangements are present). It is important to differentiate these lymphomas from the larger group of double-expressor lymphomas, which have increased expression of MYC and BCL-2 and/or BCL-6 by immunohistochemistry, by using variable cutoff percentages to define positivity. Patients with double-hit lymphomas have a poor prognosis when treated with standard chemoimmunotherapy and have increased risk of central nervous system involvement and progression. Double-hit lymphomas may arise as a consequence of the transformation of the underlying indolent lymphoma. There are no published prospective trials in double-hit lymphoma, however retrospective studies strongly suggest that aggressive induction regimens may confer a superior outcome. In this article, I review my approach to the evaluation and treatment of double-hit lymphoma, with an eye toward future clinical trials incorporating rational targeted agents into the therapeutic armamentarium. © 2017 by The American Society of Hematology.

Multidrug resistance is the most common cause of treatment failure in dogs with multicentric lymphoma. 5-(3,3-Dimethyl-1-triazeno)-imidazole-4-carboxamide (DTIC) is an atypical alkylator used as standard treatment in human Hodgkin's lymphoma, and has been effective in combination treatment to treat resistant lymphoma in dogs. However, no data are available on the use of DTIC as a single agent in the treatment of relapsed canine lymphoma. Single-agent DTIC is effective and safe in treating dogs with lymphoma that relapsed or failed to respond to previous chemotherapy. Forty client-owned dogs with relapsed lymphoma. Dogs were eligible for the retrospective study if they had a histologically or cytologically confirmed diagnosis of lymphoma and had relapsed. Dogs received DTIC (800-1,000 mg/m(2) every 2-3 weeks as a 4-5-hour IV infusion) and were evaluated for response rate and duration. Hematologic and gastrointestinal toxicity was assessed. The overall response rate for dogs being treated with DTIC was 35% (14 dogs) with a median progression-free interval of 43 days. Thirteen dogs had a partial response and 1 dog had a complete response. Stable disease was achieved in 3 dogs. Mild gastrointestinal toxicity was reported in 3 dogs posttreatment. Thrombocytopenia was the principal toxicity observed 7-14 days after the treatment. Treatments were delayed because of thrombocytopenia. DTIC, when used alone, is effective in the treatment of dogs with relapsed lymphoma.

To investigate whether the integrity of the interdigitation zone band, the ellipsoid zone band, and the external limiting membrane are reliable markers of treatment outcome in diabetic macular edema (DME). In this retrospective study, we examined 41 treatment-naïve eyes (38 patients) with DME that were treated with laser therapy, pharmacotherapy, and/or vitrectomy. Best-corrected visual acuity and the integrity of the interdigitation zone band, the ellipsoid zone band, and the external limiting membrane were assessed before treatment and at 3, 6, and 12 months after DME treatment. One year after treatment, the external limiting membrane, ellipsoid zone band, and interdigitation zone band were completely visible in 30 (73.2%), 24 (58.5%), and 2 (4.9%) eyes, respectively. Interdigitation zone band status improved significantly (P = 0.005) 1 year after treatment. The interdigitation zone did not improve in the absence of the ellipsoid zone band. Likewise, ellipsoid zone status did not improve in the absence of the external limiting membrane at any time after treatment. The results of this study show that restoration of the interdigitation zone band constitutes a very sensitive marker of DME treatment outcome when the ellipsoid zone band is visible before treatment.

Fundamentals of the management of non-Hodgkin lymphoma.

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.

Marginal zone lymphoma-derived interfollicular diffuse large B-cell lymphoma harboring 20q12 chromosomal deletion and missense mutation of BIRC3 gene: a case report.

Diffuse large B-cell lymphoma (DLBCL) typically leads to effacement of the nodal architecture by an infiltrate of malignant cells. Rarely (<1%), DLBCL can present with an interfollicular pattern (DLBCL-IF) preserving the lymphoid follicles. It has been postulated that DLBCL-IF is derived from marginal zone B cells and may represent a large-cell transformation of marginal zone lymphoma (MZL), however no direct evidence has been provided to date. Here we describe a rare case of a diagnostically challenging DLBCL-IF involving a lymph node in a patient with a prior history of lymphadenopathy for several years and MZL involving skin. A 53-year old man presented to our Dermatology Clinic due to a 1-year history of generalized itching, fatigue of 2-3 month's duration, nausea and mid back rash that was biopsied. PET (positron emission tomography)/CT (computed tomography) was performed and revealed inguinal, pelvic, retroperitoneal, axillary, and cervical lymphadenopathy. The patient was referred to surgery for excisional biopsy of a right inguinal lymph node. Diagnostic H&E stained slides and ancillary studies were reviewed for the lymph node and skin specimens. B-cell clonality by PCR and sequencing studies were performed on both specimens. We demonstrate that this patient's MZL and DLBCL-IF are clonally related, strongly suggesting that transformation of MZL to DLBCL had occurred. Furthermore, we identified a novel deletion of the long arm of chromosome 20 (del(20q12)) and a missense mutation in BIRC3 (Baculoviral IAP repeat-containing protein 3) in this patient's DLBCL that are absent from his MZL, suggesting that these genetic alterations contributed to the large cell transformation. To our knowledge, this is the first report providing molecular evidence for a previously suspected link between MZL and DLBCL-IF. In addition, we describe for the first time del(20q12) and a missense mutation in BIRC3 in DLBCL. Our findings also raise awareness of DLBCL-IF and discuss the

These rare lymphomas are usually presented in the clinic as disseminations secondary to chronic lymphocytic leukaemia, and the primary site is rare in the orbit. Non-Hodgkin lymphomas are a heterogeneous group of tumours. Although treatment in the IE stage is usually radiotherapy, due to its association with antiphospholipid syndrome, systemic treatment with rituximab was administered.

2010-06-01

Mucosa-associated lymphoid tissue (MALT) lymphoma, or extranodal marginal zone lymphoma of MALT, is an indolent B-cell non-Hodgkin lymphoma arising in lymphoid infiltrates that are induced by chronic inflammation in extranodal sites. The stomach is the most commonly affected organ, in which MALT lymphoma pathogenesis is clearly associated with Helicobacter pylori gastroduodenitis. Gastric MALT lymphoma has attracted attention because of the involvement of genetic aberrations in the nuclear factor kappaB (NFkappaB) pathway, one of the most investigated pathways in the fields of immunology and oncology. This Review presents gastric MALT lymphoma as an outstanding example of the close pathogenetic link between chronic inflammation and tumor development, and describes how this information can be integrated into daily clinical practice. Gastric MALT lymphoma is considered one of the best models of how genetic events lead to oncogenesis, determine tumor biology, dictate clinical behavior and represent viable therapeutic targets. Moreover, in view of the association of gastric MALT lymphoma with dysregulation of the NFkappaB pathway, this signaling pathway will be discussed in depth in both normal and pathological conditions, highlighting strategies to identify new therapeutic targets in this lymphoma.

To provide the overall spectrum of gastrosplenic fistula (GSF) occurring in lymphomas through a systematic review including a patient at our hospital. A comprehensive literature search was performed in the MEDLINE database to identify studies of GSF occurring in lymphomas. A computerized search of our institutional database was also performed. In all cases, we analyzed the clinicopathologic/radiologic features, treatment and outcome of GSF occurring in lymphomas. A literature search identified 25 relevant studies with 26 patients. Our institutional data search added 1 patient. Systematic review of the total 27 cases revealed that GSF occurred mainly in diffuse, large B-cell lymphoma ( n = 23), but also in diffuse, histiocytic lymphoma ( n = 1), Hodgkin's lymphoma ( n = 2), and NK/T-cell lymphoma ( n = 1, our patient). The common clinical presentations are constitutional symptoms ( n = 20) and abdominal pain ( n = 17), although acute gastrointestinal bleeding ( n = 6) and infection symptoms due to splenic abscess ( n = 3) are also noted. In all patients, computed tomography scanning was very helpful for diagnosing GSF and for evaluating the lymphoma extent. GSF could occur either post-chemotherapy ( n = 10) or spontaneously ( n = 17). Surgical resection has been the most common treatment. Once patients have recovered from the acute illness status after undergoing surgery, their long-term outcome has been favorable. This systematic review provides an overview of GSF occurring in lymphomas, and will be helpful in making physicians aware of this rare disease entity.

Background Phosphatidylinositol-3-kinase delta (PI3Kδ) mediates B-cell receptor signaling and microenvironmental support signals that promote the growth and survival of malignant B lymphocytes. In a phase 1 study, idelalisib, an orally active selective PI3Kδ inhibitor, showed antitumor activity in patients with previously treated indolent non-Hodgkin's lymphomas. Methods In this single-group, open-label, phase 2 study, 125 patients with indolent non-Hodgkin's lymphomas who had not had a response to rituximab and an alkylating agent or had had a relapse within 6 months after receipt of those therapies were administered idelalisib, 150 mg twice daily, until the disease progressed or the patient withdrew from the study. The primary end point was the overall rate of response; secondary end points included the duration of response, progression-free survival, and safety. Results The median age of the patients was 64 years (range, 33 to 87); patients had received a median of four prior therapies (range, 2 to 12). Subtypes of indolent non-Hodgkin's lymphoma included follicular lymphoma (72 patients), small lymphocytic lymphoma (28), marginal-zone lymphoma (15), and lymphoplasmacytic lymphoma with or without Waldenström's macroglobulinemia (10). The response rate was 57% (71 of 125 patients), with 6% meeting the criteria for a complete response. The median time to a response was 1.9 months, the median duration of response was 12.5 months, and the median progression-free survival was 11 months. Similar response rates were observed across all subtypes of indolent non-Hodgkin's lymphoma, though the numbers were small for some categories. The most common adverse events of grade 3 or higher were neutropenia (in 27% of the patients), elevations in aminotransferase levels (in 13%), diarrhea (in 13%), and pneumonia (in 7%). Conclusions In this single-group study, idelalisib showed antitumor activity with an acceptable safety profile in patients with indolent non

OBJECTIVE To determine the effect of prednisone omission from a multidrug chemotherapy protocol on outcome in dogs with peripheral nodal lymphomas. DESIGN Single-center, nonblinded, parallel-group, randomized, controlled trial. ANIMALS 40 client-owned dogs with a histopathologically confirmed diagnosis of peripheral nodal lymphoma and an expected survival time of > 4 weeks with treatment. PROCEDURES Treatment consisted of a combination of L-asparaginase, cyclophosphamide, doxorubicin, vincristine, and prednisone (L-CHOP) or an identical protocol except for the omission of prednisone (L-CHO). The primary outcome of interest was progression-free survival time. Veterinary caregivers and assessors of outcome were not blinded to treatment assignment. Treatment assignment was concealed from the owners of study dogs prior to enrollment, but was revealed after written informed consent was provided. RESULTS The trial was terminated early because of slow enrollment. The 40 dogs successfully enrolled in the study were randomly assigned to the L-CHOP (n = 18) or L-CHO (22) group; results for all 40 dogs were analyzed with respect to the primary outcome. Median progression-free survival time was 142.5 days for dogs receiving L-CHO and 292 days for dogs receiving L-CHOP (hazard ratio, 1.79; 95% confidence interval, 0.85 to 3.75). Serious adverse events were more common among dogs receiving L-CHO. However, this difference was not significant. CONCLUSIONS AND CLINICAL RELEVANCE The exclusion of prednisone from the L-CHOP protocol did not appear to result in improved progression-free survival time for dogs with peripheral nodal lymphomas. However, the present trial was likely underpowered to detect a clinically meaningful difference in progression-free survival time between groups.

Pilot study of sodium phenylbutyrate as adjuvant in cyclophosphamide-resistant endemic Burkitt's lymphoma.

Burkitt's lymphoma (BL) accounts for the majority of childhood malignancies seen in sub-Saharan Africa. In Malawi, cyclophosphamide (CPM), the mainstay of treatment for endemic BL, is effective in around 50% of cases. Evidence exists in support of an association between activation of replication of Epstein-Barr virus (EBV) in the tumour and response to this chemotheraupeutic agent. Phenylbutyrate (PB), approved for treatment of inborn errors of the urea cycle with minimal toxicity in children, induces EBV replication and cell lysis in BL-derived cell cultures. It has also shown some success as adjuvant in treatment of chronic leukaemia and lymphoma. We tested in African BL patients with CPM-resistant tumours, and thus unlikely to survive, the hypothesis that PB can reverse this resistance. A study of five patients showed PB before CPM to induce shrinkage of CPM-resistant tumours in two of them. Findings suggested that for this effect PB pre-treatment should be given for a week before CPM treatment. A larger study is indicated.

Current and emerging treatment options for mantle cell lymphoma

PubMed Central

Fakhri, Bita; Kahl, Brad

Mantle cell lymphoma (MCL) is a B-cell non-Hodgkin lymphoma with typically aggressive behavior. The genetic signature is the chromosomal translocation t(11;14)(q13;q32) resulting in overexpression of cyclin D1. Asymptomatic newly diagnosed MCL patients with low tumor burden can be closely observed, deferring therapy to the time of disease progression. Although MCL classically responds to upfront chemotherapy, it remains incurable with standard approaches. For patients in need of frontline therapy, the initial decision is whether to proceed with an intensive treatment strategy or a non-intensive treatment strategy. In general, given the unfavorable risk–benefit profile, older MCL patients should be spared intensive strategies, while younger and fit patients can be considered for intensive strategies. The bendamustine and rituximab (BR) regimen is becoming an increasingly popular treatment option among the elderly population, with improved progression-free survival (PFS) and acceptable side-effect profile. Although rituximab maintenance after R-CHOP improves survival outcomes in elderly patients, no clinical trial to date has shown statistical significance to support the use of rituximab maintenance after BR induction in older patients. In young and fit patients with MCL, an intensive strategy to maximize the length of first remission has emerged as a worldwide standard of care. With current high-dose cytarabine-containing immunochemotherapy regimens followed by autologous stem cell transplantation, the median PFS has exceeded 7 years. In the relapsed or refractory (R/R) setting, reduced intensity conditioning allogeneic hematopoietic stem cell transplantation may offer the highest likelihood of long-term survival in young R/R MCL patients, at the cost of increased risk of non-relapse mortality and chronic graft versus host disease. Novel agents targeting activated pathways in MCL cells, such as bortezomib, lenalidamide, ibrutinib and temsirolimus are now available

B cell lymphoma, unclassifiable, with features of diffuse large B cell lymphoma and classical Hodgkin's lymphoma (BCLu-DLBCL/CHL) is more commonly known as gray zone lymphoma. These cases more often present with mediastinal disease. In this report, we present a very rare case of BCLu-DLBCL/CHL without mediastinal involvement, transformed from follicular lymphoma (FL) to BCLu-DLBCL/CHL. This patient initially presented with a mass in the right neck; biopsy of the lymph node showed predominantly nodular, follicular pattern. Immunohistochemical (IHC) staining of tumor cells expressed positivity for mature B cell markers CD20, CD19, CD10, CD23, CD45, and CD38 but negative for CD5,11c. Hence, diagnosed with FL, he was given rituximab, cyclophosphamide, vincristine, and prednisone (RCVP) regimen, followed by maintenance rituximab. He showed good response. After 2 years, he presented again with a mass in the right side of the neck. Although the needle core biopsy of this mass was suggestive of B cell lymphoma, excisional biopsy showed morphological features of DLBCL as well as foci of histological pattern of CHL. IHC staining expressed positivity for CD20, CD79a, PAX5, and CD15 and CD30 consistent with DLBCL and CHL. He was diagnosed with BCLu-DLBCL/CHL. The patient received “ACVBP” (doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisone) followed by radiation. BCLu-DLBCL/CHL is clinically an aggressive tumor with poorer outcomes, but our case showed complete response to ACVBP regimen with tumor regression. PMID:26380128

CXCR5 [chemokine (C-X-C motif) receptor 5; also known as Burkitt lymphoma receptor 1 (BCR1)] is expressed on mature B-cells, subsets of CD4+ and CD8+ T-cells, and skin-derived migratory dendritic cells. Together with its ligand, CXCL13, CXCR5 is involved in guiding B-cells into the B-cell zones of secondary lymphoid organs as well as T-cell migration. This study evaluated the role of common germline genetic variation in CXCR5 in the risk and prognosis of non-Hodgkin lymphoma (NHL) using a clinic-based study of 1521 controls and 2694 NHL cases including 710 chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL), 586 diffuse large B-cell lymphoma (DLBCL), 588 follicular lymphoma (FL), 137 mantle cell lymphoma (MCL), 230 marginal zone lymphoma (MZL) and 158 peripheral T-cell lymphoma (PTCL). Of the ten CXCR5 tag SNPs in our study, five were associated with risk of NHL, with rs1790192 having the strongest association (OR=1.19, 95%CI 1.08–1.30; p=0.0003). This SNP was most strongly associated with the risk of FL (OR=1.44, 95%CI 1.25–1.66; p=3.1×10−7), with a lower degree of association with DLBCL (OR=1.16, 95%CI 1.01–1.33; p=0.04) and PTCL (OR=1.29, 95%CI 1.02–1.64; p=0.04) but no association with the risk of MCL or MZL. For FL patients that were observed as initial disease management, the number of minor alleles of rs1790192 was associated with better event-free survival (EFS) (HR=0.64; 95%CI 0.47–0.87; p=0.004). These results provide additional evidence for a role of host genetic variation in CXCR5 in lymphomagenesis, particularly for FL. PMID:23812490

Despite enormous advances in our understanding of aggressive lymphomas, it is clear that progress in the peripheral T-cell lymphomas (PTCL) has lagged well behind other B-cell malignancies. Although there are many reasons for this, the one commonly cited notes that the paradigms for diffuse large B-cell lymphoma (DLBCL) were merely applied to all patients with PTCL, the classic "one-size-fits-all" approach. Despite these challenges, progress is being made. Recently, the FDA has approved four drugs for patients with relapsed/refractory PTCL over the past 5 years, and if one counts the recent Japanese approval of the anti-CCR4 monoclonal antibody for patients with adult T-cell leukemia/lymphoma, five drugs have been approved worldwide. These efforts have led to the initiation of no fewer than four randomized clinical studies exploring the integration of these new agents into standard CHOP (cyclophosphamide-Adriamycin-vincristine-prednisone)-based chemotherapy regimens for patients with newly diagnosed PTCL. In addition, a new wave of studies are exploring the merits of novel drug combinations in the disease, an effort to build on the obvious single-agent successes. What has emerged most recently is the recognition that the PTCL may be a disease-characterized by epigenetic dysregulation, which may help explain its sensitivity to histone deacetylase (HDAC) inhibitors, and open the door for even more creative combination approaches. Nonetheless, advances made over a relatively short period of time are changing how we now view these diseases and, hopefully, have poised us to finally improve its prognosis.

EUS-guided FNA and Tru-cut biopsy (TCB) is highly accurate in the diagnosis of lymphoma. Subclassification, however, may be difficult in low-grade non-Hodgkin lymphoma and Hodgkin lymphoma. To determine the yield of EUS-guided biopsy to classify lymphoma based on the World Health Organization classification of tumors of hematopoietic lymphoid tissues. Retrospective study. Tertiary referral center. A total of 24 patients referred for EUS-guided biopsy who had a final diagnosis of lymphoma or "highly suspicious for lymphoma." EUS-guided FNA and TCB combined with flow cytometry (FC) analysis. MAIN OUTCOMES MEASUREMENT: Lymphoma subclassification accuracy of EUS guided biopsy. Twenty-four patients were included in this study. Twenty-three patients underwent EUS-FNA, and 1 patient had only TCB. Twenty-two underwent EUS-TCB combined with FNA. EUS correctly diagnosed lymphoma in 19 out of 24 patients (79%), and subclassification was determined in 16 patients (66.6%). Flow cytometry correctly identified B-cell monoclonality in 95% (18 out of 19). In 1 patient diagnosed as having marginal-zone lymphoma by EUS-FNA/FC only, the diagnosis was changed to hairy cell leukemia after a bone marrow biopsy was obtained. EUS had a lower yield in nonlarge B-cell lymphoma (only 9 out of 15 cases [60%]) compared with large B-cell lymphoma (78%; P = .3 [Fisher exact test]). Retrospective, small number of patients. EUS-guided biopsy has a lower yield to correctly classify Hodgkin lymphoma and low-grade lymphoma compared with high-grade diffuse large B-cell lymphoma.
