    Relatively few cases of Epstein-Barr (EBV)-positive B-cell lymphomas arising in patients with angioimmunoblastic T-cell lymphoma (AITL) have been reported. We report a case of AITL in which diffuse large B-cell lymphoma arose 13 months after the initial diagnosis of AITL. In a 36-year-old female patient, evaluated for moderate leukocytosis, peripheral and abdominal lymphadenopathy AITL was diagnosed in March 2008, based on results of fine-needle aspiration cytology (FNAC) of the enlarged cervical and supraclavicular lymph nodes. The diagnosis was also confirmed by immunophenotyping and histopathology of the cervical lymph nodes. The patient initially recieved FED chemotherapy (fludarabine, cyclophosphamide, dexamethasone) followed by elective autologous hematopoietic stem cell transplantation. In April 2009 the patient was hospitalized because of fever, pancytopenia, hyperbilirubinemia and peripheral lymphadenopathy. The FNAC of the enlarged cervical lymph nodes was performed again, but this time the smears were composed of polymorphous population of lymphocytes with the predomination of large cells, CD20+ on immunocytochemical stains. The immunophenotyping confirmed a predomination of monoclonal mature B-cells. Patient had high number of EBV DNA copies in plasma and serologic testing revealed increased titers of EBV VCA IgG and EBV EBNA IgG. CHOP-R chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab) was then administered, resulting in good partial response of the disease. Reduced intensity allogeneic stem cell transplantation performed thereafter, resulted in complete remission of the disease. AITL is a rare lymphoproliferative disorder in which the neoplastic T-cells represent the minority of the lymph node cell population and almost all cases harbor EBV-infected B-cells. Various authors postulated that immunodeficiency in AITL patients together with immunosuppressive effects of cytotoxic drugs, may be responsible for EBV

    Full Text Available Objective: This series of six intestinal T cell lymphomas (ITCL attempts to document enteropathy-associated T cell lymphoma (EATCL in India. Materials and Methods: A total of six ITCL were selected from 170 gastrointestinal lymphomas in last 10 years. Results: The cases studied included EATCL (4, ITCL with a CD4 positive phenotype (1 and ITCL NK/T cell type (1. Of the four EATCL, two occurred in the ileum, one in right colon and one in duodenum. In three EATCL cases, there was history of celiac disease or lactose intolerance and enteropathic changes were noted in the adjacent mucosa. These tumors had CD3+/CD8+/CD56 (+/-/CD4-/ Granzyme B+ immunophenotype. One EATCL was monomorphic small cell type (type II EATCL with a CD3+/CD8-CD56+/CD4-/ Granzyme B+ phenotype. EBER- ISH (Epstein Barr virus coded RNA′s- in situ hybridization revealed positive tumor cells in ITCL NK/T cell type and in bystander cells in three EATCL. Conclusion: ITCL are rare in Indian patients but do occur and comprise a mixture of the enteropathic and non-enteropathic subtypes.

    Despite unprecedented clinical activity in mantle cell lymphoma (MCL), primary and acquired resistance to ibrutinib is common. The outcomes and ideal management of patients who experience ibrutinib failure are unclear. We performed a retrospective cohort study of all patients with MCL who experienced disease progression while receiving ibrutinib across 15 international sites. Medical records were evaluated for clinical characteristics, pathological and radiological data, and therapies used pre- and postibrutinib. A total of 114 subjects met eligibility criteria. The median number of prior therapies was 3 (range, 0-10). The Mantle Cell Lymphoma International Prognostic Index (MIPI) scores at the start of ibrutinib were low, intermediate, and high in 46%, 31%, and 23% of patients, respectively. Of patients with available data prior to ibrutinib and postibrutinib, 34 of 47 and 11 of 12 had a Ki67 >30%. The median time on ibrutinib was 4.7 months (range 0.7-43.6). The median overall survival (OS) following cessation of ibrutinib was 2.9 months (95% confidence interval [CI], 1.6-4.9). Of the 104 patients with data available, 73 underwent subsequent treatment an average of 0.3 months after stopping ibrutinib with a median OS of 5.8 months (95% CI, 3.7-10.4). Multivariate Cox regression analysis of MIPI before postibrutinib treatment, and subsequent treatment with bendamustine, cytarabine, or lenalidomide failed to reveal any association with OS. Poor clinical outcomes were noted in the majority of patients with primary or secondary ibrutinib resistance. We could not identify treatments that clearly improved outcomes. Future trials should focus on understanding the mechanisms of ibrutinib resistance and on treatment after ibrutinib. PMID:26764355

  5. My treatment approach to patients with diffuse large B-cell lymphoma.

    2012-02-01

    My favored treatment approach for patients with diffuse large B-cell lymphoma continues to evolve. Diffuse large B-cell lymphoma can now be cured in more than 50% of patients. This is a result of improved definitions of the disease, improved diagnostic capabilities, better staging and restaging techniques, a useful prognostic index to guide therapeutic decisions, and the development of increasingly effective therapies. Positron emission tomographic scans have improved the accuracy of both staging and restaging. Findings on a positron emission tomographic scan at the end of therapy are the best predictors of a good treatment outcome. Numerous subtypes of diffuse large B-cell lymphoma have been identified that require specific treatment approaches. For example, plasmablastic lymphoma typically lacks CD20 and does not benefit from treatment with rituximab. Diffuse large B-cell lymphoma originating in specific extranodal sites such as the central nervous system, testes, and skin presents special problems and requires specific treatment approaches. A subgroup of diffuse large B-cell lymphoma with a very high proliferative rate seems to have a poor outcome when treated with CHOP-R and does better with regimens used for patients with Burkitt lymphoma. New insights into the biology of these disorders are likely to further change treatment approaches. Recognition that diffuse large B-cell lymphoma is not one disease, but a variety of clinicopathologic syndromes provides the opportunity to further improve our ability to benefit patients.

    International Nuclear Information System (INIS)

    Since 1994, 17 breast cancer patients and 16 lymphoma patients have been treated at the Norwegian Radium Hospital with high-dose therapy supported by autologous peripheral progenitor cells. All the patients were given granulocyte colony stimulating factor in the recovery phase after cytotoxic treatment in order to mobilize and harvest peripheral progenitor cells. Aphareses were successful in all patients and the mean number of CD34 cells reinfused per kilo body weight was 8.05x106 for the lymphoma patients and 11.1x106 for the breast cancer patients. The mean time to recover≥0.5x109/l granulocytes and ≥20x109/l platelets after reinfusion of stem cells was 10 days and 11.7 days respectively for the lymphoma patients, while the breast cancer patients engrafted at day 8.6 and day 9.3.

Most of quality of life (QoL studies in lymphomas patients received HSCT limited on parameters dynamics assessment in the early and late post-transplant period. Aim of this study was to evaluate the QoL parameters and their prognostic significance in lymphoma patients before transplantation. 124 patients with lymphomas (non-Hodgkin lymphomas – 45 patients, Hodgkin's lymphoma – 79 patients who received HD-PCT + auto-HSCT were included in the study: men – 42.7 % (n = 53, women – 57.3 % (n = 71, median age – 34 years (19–65 years. Patients’ heterogeneity before transplantation regarding quality of life has been revealed. Almost 1/3 of patients showed a significant reduction in the integral index of QoL. Insignificant differences between patients with chemosensitivity and chemoresistant lymphomas regarding QoL before HD-PCT + auto-HSCT were shown. We also analyzed the outcomes of studied patients received HD-PCT + auto-HSCT. With a median follow-up of 18 months, overall survival after transplantation was 72 % (95 % CI 56–84; event-free survival – 64 % (95 % CI 53,3–73,2.Overall and event-free survivals were significantly higher in patients with chemosensitive lymphoma compared with chemoresistance tumor. Differences in the survival rates between patients with no or negligible decrease of QoL integral index and with significant reduction of it also were found. Revealed differences in overall and event-free survival between the groups allowed the first group considered as patients with a favorable prognosis, and the second group – as patients with poor prognosis regarding the transplantation outcome.

Patients’ heterogeneity before transplantation regarding quality of life has been revealed. Almost 1/3 of patients showed a significant reduction in the integral index of QoL. Insignificant differences between patients with chemosensitivity and chemoresistant lymphomas regarding QoL before HD-PCT + auto-HSCT were shown. We also analyzed the outcomes of studied patients received HD-PCT + auto-HSCT. With a median follow-up of 18 months, overall survival after transplantation was 72 % (95 % CI 56–84; event-free survival – 64 % (95 % CI 53,3–73,2.Overall and event-free survivals were significantly higher in patients with chemosensitive lymphoma compared with chemoresistance tumor. Differences in the survival rates between patients with no or negligible decrease of QoL integral index and with significant reduction of it also were found. Revealed differences in overall and event-free survival between the groups allowed the first group considered as patients with a favorable prognosis, and the second group – as patients with poor prognosis regarding the transplantation outcome.

    B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma (iBL/DLBCL), is a rare, but an aggressive subtype. In iBL/DLBCL, clinicopathological prognostic factors, including MYC and BCL2 translocations (double hit translocation, DHT) and the expression of both MYC and BCL2 (double hit score 2, DHS2), have not been studied thoroughly. We retrospectively analyzed the prognostic impact of clinicopathological factors, including MYC split, IGH/BCL2 fusion, MYC and BCL2 expressions, in 24 iBL/DLBCL patients (median age: 47 years). Fifteen patients (62 %) underwent intensive chemotherapy, and nine patients (38 %) underwent rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP). The 5-year progression-free (PFS) and overall survival (OS) rates of intensive chemotherapy and R-CHOP were 57 and 72 %, respectively. PFS was significantly shorter in patients with high IPI score (P < .0001), stage IV (P = .001), aged ≥60 years (P = .042), IGH/BCL2 fusion (P = .029), DHS2 (P = .015), and DHT (P = .03). OS was significantly shorter in patients with high IPI score (P < .0001) and aged ≥60 years (P = .008). In iBL/DLBCL, IGH/BCL2 fusion, DHS2, and DHT were pathological prognostic factors for poor PFS, while IPI remained as more predictive for PFS and OS. PMID:27095041

    Full Text Available Sjögren’s syndrome (SS has the highest incidence of malignant lymphoproliferative disorders transformation among autoimmune diseases. We present a case of extranodal high grade lymphoma of the liver in a 52-year-old patient with long history of SS. Lymphoma manifested with sharp significant pain in the right hypochondrium, weakness, and profuse night sweats. Contrast-enhanced computed tomography scan (CT-scan of the abdomen revealed multiple low density foci with homogeneous structure and clear contours in both lobes of the liver. Histologically, proliferation of medium sized lymphoma cells with round-oval and slightly irregular nuclei with fine chromatin was shown. Immunohistochemical and molecular features of the tumors allowed diagnosis of diffuse large B-cell lymphoma (DLBCL. To exclude secondary liver lesion by non-Hodgkin lymphoma, chest and small pelvis CT-scan, endoscopy of upper and lower gastrointestinal tract and study of bone marrow were performed. After 8 cycles of R-CHOP chemotherapy (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, the complete remission was achieved, which persists after 45 months of follow-up. Primary hepatic lymphomas are extremely rare, and previously only low-grade hepatic lymphomas have been described in SS. To our knowledge, the patient described here represents the first reported case of DLBCL with primary liver involvement in SS.

    Rituximab has been associated with the development of cytomegalovirus enterocolitis in immunosuppressed patients. A 51-year-old patient with diffuse large B-cell lymphoma who received a conditioning chemotherapy regimen (RCVP and RICE) consisting of rituximab before bone marrow transplantation went on to develop cytomegalovirus enterocolitis. This supports evidence from previously described cases that rituximab may be associated with cytomegalovirus enterocolitis.

    2016-04-01

    Full Text Available The nontraumatic perforations of the small intestine are pathological entities with particular aspects in respect to diagnosis and treatment. These peculiarities derive from the nonspecific clinical expression of the peritonitis syndrome, and from the multitude of causes that might be the primary sources of the perforation: foreign bodies, inflammatory diseases, tumors, infectious diseases, etc. Accordingly, in most cases intestinal perforation is discovered only by laparotomy and the definitive diagnosis is available only after histopathologic examination. Small bowel malignancies are rare; among them, lymphomas rank third in frequency, being mostly B-cell non Hodgkin lymphomas. Only 10% of non-Hodgkin lymphomas are with T-cell. We report the case of a 57 years’ old woman with intestinal T-cell lymphoma, whose first clinical symptomatology was related to a complication represented by perforation of the small intestine. Laparotomy performed in emergency identified an ulcerative lesion with perforation in the jejunum, which required segmental enterectomy with anastomosis. The nonspecific clinical manifestations of intestinal lymphomas make from diagnosis a difficult procedure. Due to the fact that surgery does not have a definite place in the treatment of the small intestinal lymphomas (for cases complicated with perforation, and beyond the morbidity associated with the surgery performed in emergency conditions, prognosis of these patients is finally given by the possibility to control the systemic disease through adjuvant therapy.

    Full Text Available Abstract Introduction Schwannomas are mostly benign tumors arising from Schwann cells of the nerve sheaths. Breast schwannomas are very rare and account for only 2.6% of cases. As far as we know this is the first reported case of breast schwannoma discovered in a patient with diffuse large B-cell lymphoma. The breast schwannoma was evaluated with positron emission tomography and it exhibited moderate 18F-fluorodeoxyglucose uptake. Case presentation We present the case of a breast schwannoma in a 63-year-old Caucasian woman who was diagnosed with diffuse large B-cell lymphoma. Conclusion Imaging modalities including positron emission tomography-computed tomography failed to distinguish breast schwannoma from diffuse large B-cell lymphoma involvement of the breast.

  7. Proton beam therapy in a patient with cutaneous T cell lymphoma of the penis

    International Nuclear Information System (INIS)

    A 68-year-old man had multiple tumors as the relapse sign of cutaneous T cell lymphoma. The patient received proton beam therapy with a total dose of 21 Gy for local recurrent lymphoma on the ventral side of the penis. The tumor began to decrease, with concomitant erosion, by delivering 8 Gy. It completely disappeared at 4 days after the completion of irradiation schedule. The erosion was the severest at one month after that. Hematuria and difficulty in urination were not observed. Postmortem histology showed no evidence of viable cancer cells. The use of conventional radiation may induce radiation injuries to the surrounding critical organ, although lymphoma has been recognized as radiosensitive. In view of no evidence of urethral damage, as observed in this patient, proton beams are considered suitable in radiation treatment for the penis. (Namekawa, K.)

    The development of a de novo lymphoma in patients affected by chronic myelogenous leukemia (CML) is a rare event. The introduction of new molecular cytogenetic techniques, such as fluorescence in situ hybridization (FISH), allows a correct differential diagnosis between lymphoid blastic crisis and a blastoid variant of mantle cell lymphoma (MCL), which shows an aggressive behavior and some molecular characteristics detectable by cytogenetics and immunohistochemistry. We report a case of a blastoid variant of MCL that developed in a patient with CML who achieved complete cytogenetic and molecular response to imatinib mesylate treatment. PMID:17353181

    Gray zone lymphomas are defined as lymphoid malignancies that cannot be reliably classified into a single distinct disease entity after all available morphologic, immunophenotypic, and molecular investigations have been performed. The 2008 World Health Organization Classification proposed 2 gray zone lesions: (1) B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma and (2) B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma. These gray zone lesions are rare, especially in pediatric patients, and create a great challenge to both pathologists and oncologists because this differential diagnosis has direct implications for management strategies. In this manuscript, we report 2 cases of pediatric patients with gray zone lymphoma and review clinicopathologic features, treatment options, and outcomes of this uncommon tumor. PMID:20331368

    2016-01-01

    Although Anaplastic Large Cell Lymphomas (ALCL) carrying Anaplastic Lymphoma Kinase (ALK) have a relatively good prognosis, aggressive forms exist. We have identified a novel translocation, causing the fusion of the TRAF1 and ALK genes, in one patient who presented with a leukemic ALK+ ALCL (ALCL-11). To uncover the mechanisms leading to high-grade ALCL, we developed a human Patient Derived Tumorgraft (hPDT) line. Molecular characterization of primary and PDT cells demonstrated the activation of ALK and of NFkB pathways. Genomic studies of ALCL-11 showed the TP53 loss and the in vivo subclonal expansion of lymphoma cells lacking PRDM1/Blimp-1 and with c-MYC gene amplification. The treatment with proteasome inhibitors of TRAF1-ALK cells led to down-regulation of p50/p52 and lymphoma growth inhibition. Moreover a NFkB gene set classifier stratified ALCL in distinct subsets with different clinical outcome. Moreover, a selective ALK inhibitor (CEP28122) resulted in a significant clinical response of hPDT mice, but the disease could not be eradicated. These data indicate that the activation of NFkB signaling contributes to the neoplastic phenotype of TRAF1-ALK ALCL. ALCL hPDTs are invaluable to validate the role of druggable molecules, predict therapeutic responses and are helpful tools for the implementation of patient specific therapies. PMID:25533804

    We evaluated the combination of rituximab with chlorambucil in patients with mantle cell lymphoma (MCL) not eligible for aggressive therapy. Fourteen patients (male/female: 9/5) were included (two newly diagnosed, 12 relapsed/refractory). The toxicities were neutropenia, thrombopenia and infection. Nine (64%) patients responded; five (36%) achieved complete remission and four (29%) achieved partial remission. The median progression-free survival for responders was 26 months (95% CI, 4-48). Marrow polymerase chain reaction negativity was attained in seven responders. These results suggest that this schedule may have notable antitumour activity in patients with MCL, including patients in relapse after autologous stem cell transplantation. PMID:16225653

    Full Text Available Aim To investigate the cystatin C levels in sera of patients with aggressive non-Hodgkin B-cell lymphoma. Methods The levels of cystatin C in sera of lymphoma patients and control group consisted of healthy individuals, were measured by using speciic sandwich-type ELISA. For each patient the clinical stage of disease was determined according to Ann Arbor staging system for lymphomas. Results Our study shows that mean cystatin C serum level in the patients group (1056 ± 65 ng/mL was signiicantly higher when compared with the mean level of the healthy control group (819 ± 28 ng/mL (P=0,001. Mean cystatin C level of the group with clinical stages III and IV (1255 ± 109 ng/mL was signiicantly elevated when compared with the mean level of the group with clinical stages I and II (896 ± 51 ng/mL (P=0,03. Conclusion This inding points out a connection between inhibitor level and aggressive behaviour of lymphoma and could be considered for further strategies of prognosis of the disease.

    Full Text Available We present a 64-year-old man who was treated with R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisolone chemoimmunotherapy for mantle cell lymphoma and developed purulent meningitis, probably caused by Leuconostoc sp. The patient had severe hypogammaglobulinemia, which is a possible complication of rituximab therapy. To our knowledge and after reviewing the available medical literature, this is the first described case of purulent meningitis caused by Leuconostoc sp. in a patient with mantle cell lymphoma that appeared after treatment with the R-CHOP protocol. The diagnosis of purulent meningitis was based on clinical, laboratory and cytological cerebrospinal fluid findings, in addition to blood culture results in which we isolated Leuconostoc sp.

    2011-01-01

    Full Text Available Introduction. Waldenström’s macroglobulinaemia is a rare B cell lymphoproliferative disorder characterized by lymphoplasmocyte bone marrow infiltration and monoclonal IgM gammopathy. In the majority of cases, Waldenström’s macroglobulinaemia is a chronic disease with variable course. Therapy consists of alkylating agents, purine analogs and antiCD20 monoclonal antibody. In the literature, there have been descriptions of rare cases of progression of Waldenström’s macroglobulinaemia to aggressive lymphoma, as well as secondary carcinoma in the patients after treatment of macroglobulinaemia. Case Outline. A 63-year-old patient was diagnosed with serum monoclonal IgM kappa gammopathy (Waldenström’s macroglobulinaemia. Chemotherapy was applied and a good clinical and haematological response had been achieved. Ten years later, the patient was diagnosed with colon adenocarcinoma as a secondary malignancy, and operated on. Within one month, the patient rapidly developed a large neck tumour mass. Tumour biopsy revealed the diagnosis of diffuse large B cell lymphoma with the expression of monoclonal lambda chain, which more likely pointed out to coexistence of two different B cell lymphoproliferative disorders, rather than the transformation of Waldenström’s macroglobulinaemia to aggressive lymphoma. The patient was treated with chemotherapy following R-CHOP protocol, and clinical remission was achieved. Seven months later, despite the successful treatment of lymphoproliferative disorder, dissemination of adenocarcinoma led to the lethal outcome. Conclusion. The patient was diagnosed with a rare occurrence of three neoplastic diseases: Waldenström’s macroglobulinaemia, colon adenocarcinoma and diffuse large B cell lymphoma. The possible mechanisms of the combined appearance of lymphoproliferative and other malignant diseases include the previous treatment with alkylating agents, genetic, immunomodulatory and environmental factors.

    Two hundred and thirty-four scintigraphic studies were performed in 34 patients (27 men, 7 women, age 17.3±7.7 years) with small, non-cleaved cell lymphoma who had follow-up for 3-96 months (mean 21.6±21.7 months). Whole-body scintigraphy was performed 48-72 h following i.v. injection of 370 MBq gallium-67 citrate. 'Gold standards' for truth determinations were surgery, autopsy, histology, axial X-ray computed tomography, magnetic resonance imaging, ultrasonography and clinical follow-up. Overall, 181 of 234 studies were true negative. Eighty proven sites of disease had true positive 67Ga uptake (in 21 patients/37 studies). Nineteen sites (in 12 patients/15 studies) were false positive. In addition, 31 benign lesions were detected and interpreted correctly in terms of non-malignancy. Ten lymphoma sites (in 6 patients/10 studies) were missed by scintigraphy. Overall, sensitivity of gallium scintigraphy was 89% when calculated by sites and 79% when calculated by studies. Corresponding specificities were 91% and 92%, respectively. Positive predictive values were 81% (sites) and 71% (studies), and negative predictive values 95% (sites and studies). Thus, gallium scintigraphy proved to be a sensitive and specific method for staging and follow-up in patients with small, non-cleaved cell lymphoma. (orig.)

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

    Full Text Available Mantle cell lymphoma(MCL, a special type of non-Hodgkin's lymphoma, is incurable through conventional treatment. This study aimed to analyze the clinical features, therapeutic responses, and prognosis of patients with MCL. Clinical data of 30 patients with MCL treated in our hospital between April 2006 and July 2011 were analyzed. Eighteen patients were treated with CHOP plus rituximab (R-CHOP regimen, 12 underwent conventional chemotherapy. The median age of the 30 patients was 58 years, 23 were men, all patients had Cyclin D1 overexpression, 29 (96.7% had advanced disease, 11 (36.7% had bone marrow involvement, 9 (30.0% had gastrointestinal involvement, and 15 (50.0% had splenomegaly. The complete response(CR rate and overall response rate(ORR were significantly higher in patients undergoing R-CHOP immunochemotherapy than in those undergoing conventional chemotherapy (38.9% vs. 16.7%, P = 0.187; 72.2% vs. 41.4%, P = 0.098. The difference of 2-year overall survival rate between the two groups was not significant (P = 0.807 due to the short follow-up time. The 2-year progression-free survival (PFS rate was higher in R-CHOP group than in conventional chemotherapy group (53% vs. 25%, P = 0.083, and was higher in patients with a lower mantle cell lymphoma international prognostic index (MIPI (51% for MIPI 0-3, 33% for MIPI 4-5, and 0% for MIPI 6-11, P = 0.059. Most patients with MCL were elderly; in an advanced stage; showed a male predominance; and usually had bone marrow involvement, gastrointestinal involvement, or splenomegaly. R-CHOP regimen could improve the CR rate and ORR of MCL patients. MIPI can be a new prognostic index for predicting the prognosis of advanced MCL.

    Full Text Available OBJECTIVE: To investigate the incidence and risk factors of infiltration of the central nervous system after the initial treatment of diffuse large B-cell lymphoma in patients treated at Santa Casa de Misericórdia de São Paulo. METHODS: A total of 133 patients treated for diffuse large B-cell lymphoma from January 2001 to April 2008 were retrospectively analyzed in respect to the incidence and risk factors of secondary central nervous system involvement of lymphoma. Intrathecal prophylaxis was not a standard procedure for patients considered to be at risk. This analysis includes patients whether they received rituximab as first-line treatment or not. RESULTS: Nine of 133 (6.7% patients developed central nervous system disease after a mean observation time of 29 months. The median time to relapse or progression was 7.9 months after diagnosis and all but one patient died despite the treatment administered. Twenty-six (19.5% patients of this cohort received rituximab as first-line treatment and nine (7.1% received intrathecal chemoprophylaxis. Of the nine patients that relapsed, seven (77.7% had parenchymal central nervous system involvement; seven (77.7% had stage III or IV disease; one (11.1% had bone marrow involvement; two (22.2% had received intrathecal chemoprophylaxis; and 3 (33.3% had taken rituximab. In a multivariate analysis, the risk factors for this infiltration were being male, previous use of intrathecal chemotherapy and patients that were refractory to initial treatment. CONCLUSION: Central nervous system infiltration in this cohort is similar to that of previous reports in the literature. As this was a small cohort with a rare event, only three risk factors were important for this infiltration

    We retrospectively analyzed 87 patients with angioimmunoblastic T cell lymphoma (AITL) in Taiwan. The median age was 68 (range 18-89) years. Of these patients, 74 % was at an advanced stage. The most common extra-nodal site involved was bone marrow (36 %). Of these patients, 77 % were International Prognostic Index (IPI) >1 and 79 % had a prognostic index for peripheral T-cell lymphoma (PIT) >1. Of 75 patients who received systemic chemotherapy, the complete remission rate was 60 %, the relapse rate was 47 %, and the 2-year progression-free survival rate was 37.4 %. The 2-year overall survival (OS) rate for all patients was 51.9 %. By multivariate analysis, bone marrow involvement (P 1 (P = 0.007) were independent adverse factors for OS. A simplified prognostic index efficiently stratified patients into the following three groups: 2-year OS rates 79.8 % (0 factor), 28.3 % (1 factor), and 10.2 % (2 factors) by using bone marrow involvement and ECOG >1 (P prognosis in Taiwan. Bone marrow involvement, EOCG >1, IPI >1 and PIT >1 had adverse impact on OS. The usefulness of this simplified prognostic index needs further validation. PMID:27095042

    Full Text Available Diffuse large B-cell lymphoma (DLBCL, the most common lymphoma, is a heterogeneous disease where the outcome for patients with early relapse or refractory disease is very poor, even in the era of immunochemotherapy. In order to describe possible differences in global protein expression and network patterns, we performed a SILAC-based shotgun (LC-MS/MS quantitative proteomic analysis in fresh-frozen tumor tissue from two groups of DLBCL patients with totally different clinical outcome: (i early relapsed or refractory and (ii long-term progression-free patients. We could identify over 3,500 proteins; more than 1,300 were quantified in all patients and 87 were significantly differentially expressed. By functional annotation analysis on the 66 proteins overexpressed in the progression-free patient group, we found an enrichment of proteins involved in the regulation and organization of the actin cytoskeleton. Also, five proteins from actin cytoskeleton regulation, applied in a supervised regression analysis, could discriminate the two patient groups. In conclusion, SILAC-based shotgun quantitative proteomic analysis appears to be a powerful tool to explore the proteome in DLBCL tumor tissue. Also, as progression-free patients had a higher expression of proteins involved in the actin cytoskeleton protein network, such a pattern indicates a functional role in the sustained response to immunochemotherapy.

    Full Text Available Abstract Background Systemic anaplastic large cell lymphoma (S-ALCL is a rare disease with a highly variable prognosis and no standard chemotherapy regimen. Anaplastic lymphoma kinase (ALK has been reported as an important prognostic factor correlated with S-ALCL in many but not all studies. In our study, we retrospectively analyzed 92 patients with S-ALCL from the Peking University Lymphoma Center for clinical and molecular prognostic factors to make clear the role of ALK and other prognostic factors in Han Chinese S-ALCL. Results The majority of Chinese S-ALCL patients were young male patients (median age 26, male/female ratio 1.7 and the median age was younger than previous reports regardless of ALK expression status. The only statistically significant different clinical characteristic in S-ALCL between ALK positive (ALK+ and ALK negative (ALK- was age, with a younger median age of 22 for ALK+ compared with 30 for ALK-. However, when pediatric patients (≤18 were excluded, there was no age difference between ALK+ and ALK-. The groups did not differ in the proportion of males, those with clinical stage III/IV (49 vs 51% or those with extranodal disease (53 vs 59%. Of 73 evaluable patients, the 3-year and 5-year survival rates were 60% and 47%, respectively. Univariate analysis showed that three factors: advanced stage III/IV, lack of expression of ALK, and high Ki-67 expression, were associated with treatment failure in patients with S-ALCL. However, ALK expression correlated with improved survival only in patients younger than 14 years, while not in adult patients. In multivariate analysis, only clinical stage was an independent prognostic factor for survival. Expressions of Wilms tumor 1 (WT1 and B-cell lymphoma 2 protein (BCL-2 correlated with the expression of ALK, but they did not have prognostic significance. High Ki-67 expression was also a poor prognostic factor. Conclusions Our results show that ALK expression alone is not

    We retrospectively analyzed 77 patients with pathologically diagnosed angioimmunoblastic T-cell lymphoma from a single city. There were 43 men and 34 women; the median age was 64.5 years (range, 30-91 yr). Average time between first symptoms of the disease and diagnosis was 3.6 months. At diagnosis, peripheral nodes were present in all but 1 patient, and were generalized in 90% of cases. Constitutional symptoms were reported in 77% of cases and spleen enlargement in 51%. A cutaneous eruption--morbilliform, urticarial, or more polymorphic--was present in 45% of patients; in one-third of them, the eruption occurred after drug administration. Other clinical manifestations included pleuritis (22%); arthralgia or arthritis (17%); ear, nose, and throat involvement (14%); central or peripheral neurologic manifestations (10%); and ascites (5%). Most patients presented with advanced disease at diagnosis (bone marrow involvement in 60% of cases). The main laboratory abnormalities were elevated lactate dehydrogenase levels (71%), inflammatory syndrome (67%), hypergammaglobulinemia (50%), anemia (51%), and lymphopenia (52%). Auto- or disimmune manifestations were reported in one-third of patients: autoimmune hemolytic anemia was present at diagnosis in 19% of patients and thrombocytopenic purpura in 7%. Documented vasculitis was described in 12% of cases. Clonality was analyzed in lymph nodes in 47 patients: T-cell and B-cell clones were found in 45 (96%) and 20 (45%) patients, respectively. Chromosomal abnormalities were identified in 62% of cases: trisomies 3, 5, 18, 19, additional X chromosome, and deletion of chromosome 7 were the most common abnormalities. The current study underlines the diversity of presenting manifestations of angioimmunoblastic T-cell lymphoma. PMID:17873758

    Gallium scintigraphy was evaluated in 25 patients with adult T-cell leukemia lymphoma (ATLL). Anterior and posterior images were obtained at 72 h after administration of 3 mCi67Ga-citrate using a gamma camera (Maxi-Camera 400 T, General Electric Co.) with a medium energy standard parallel hole collimator. Abnormally high accumulations were observed in 17 out of 25 cases (superficial lymph node, 8; hilar and mediastinal lymph node, 7; paraaortic lymph node, 2; lung, 9; liver, 1; bone, 1). There were 10 malignant lesions detected by 67Ga scintigraphy in 9 out of 17 cases (superficial lymph node, 1; hilar and mediastinal lymph node, 6; paraaortic lymph node, 1; liver, 1; bone, 1). White blood cell count and serum LDH levels were significantly raised in patients with abnormally high accumulations of 67Ga. In conclusion, 67Ga scintigraphy seemed to be a useful examination to detect malignant lesions in patients with ATLL. (orig.)

    Full Text Available Objectives: Tumour Necrosis Factor α (TNFα and Lymphotoxin α (LTα have been implicated in the pathogenesis of lymphoproliferative disorders. Patients with B-cell non-Hodgkin’s lymphoma (NHL often have high serum levels of TNF which may be associated with a poor outcome. TNFα and LTα polymorphisms are known to influence expression of these cytokines and may explain the variable response to therapy. Patients and Methods: In patients with NHL, serum levels of TNFα and LTα were measured. DNA was typed using allele specific PCR and restriction fragment length polymorphism for the –308 TNFα and +252 LTα polymorphisms and comparison was made with clinical outcome. Results: The presence of high producing alleles was significantly associated with high serum levels of TNFα and LTα. The presence of 2 or more high producing alleles was significantly associated with more advanced disease at presentation (stage III and IV, p=0.024, a higher International Prognostic Index (IPI score, p=0.038, failure to achieve a complete remission (CR after 1st line therapy (88% vs 33%, p=0.01 and shorter progression free survival (PFS (median 24 months compared with 78 months, p=0.001. Multivariate analysis confirmed that TNF highrisk haplotype (HRH was an independent prognostic factor for PFS. Conclusions: These results demonstrate that TNF polymorphisms are independent prognostic factors in NHL. Further study is required to further define the importance of TNF polymorphisms within different lymphoma subtypes and with different therapeutic approaches.

    Mantle cell lymphoma (MCL) is a heterogeneous disease, and it has been well-established over the last decade that a subset of patients can have indolent presentation. It is therefore important to adopt a risk-stratified approach in order to minimize unnecessary toxicities while maximizing survival and quality of life in selected MCL patients. This review provides an up-to-date assessment of clinical and pathologic entities associated with indolent disease course and delineates available biomarkers with predictive significance. Initial treatment decisions should be guided by risk assessment to discern patients who might do well with deferred therapy, from those who would require treatment with non-aggressive first-line regimens.

    Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma (NHL). Although this lymphoma is curable, 40% of patients with DLBCL will die of relapsed or refractory disease. 18F-Fluoro-deoxyglucose positron emission tomography (FDG-PET) is a noninvasive, 3-dimensional, functional imaging modality. When combined with the anatomical imaging tool computed tomography (CT), PET/CT can differentiate among others necrotic masses and viable tumors. PET scan has become a basic clinical tool for staging and response assessment in aggressive lymphomas, such as DLBCL. It has been evaluated in pretreatment staging, restaging, monitoring during therapy, post-therapy surveillance and assessment of transformation. Based on the preliminary results of several studies FDG-PET scans play an important role in the early assessment of treatment response, in planning of the treatment including radiation therapy and in the estimation of prognosis.

  6. Prognostic significance of peripheral monocyte count in patients with extranodal natural killer/T-cell lymphoma

    International Nuclear Information System (INIS)

    Extranodal natural killer/T-cell lymphoma (ENKL) has heterogeneous clinical manifestations and prognosis. This study aims to evaluate the prognostic impact of absolute monocyte count (AMC) in ENKL, and provide some immunologically relevant information for better risk stratification in patients with ENKL. Retrospective data from 163 patients newly diagnosed with ENKL were analyzed. The absolute monocyte count (AMC) at diagnosis was analyzed as continuous and dichotomized variables. Independent prognostic factors of survival were determined by Cox regression analysis. The AMC at diagnosis were related to overall survival (OS) and progression-free survival (PFS) in patients with ENKL. Multivariate analysis identified AMC as independent prognostic factors of survival, independent of International Prognostic Index (IPI) and Korean prognostic index (KPI). The prognostic index incorporating AMC and absolute lymphocyte count (ALC), another surrogate factor of immune status, could be used to stratify all 163 patients with ENKL into different prognostic groups. For patients who received chemotherapy followed by radiotherapy (102 cases), the three AMC/ALC index categories identified patients with significantly different survivals. When superimposed on IPI or KPI categories, the AMC/ALC index was better able to identify high-risk patients in the low-risk IPI or KPI category. The baseline peripheral monocyte count is shown to be an effective prognostic indicator of survival in ENKL patients. The prognostic index related to tumor microenvironment might be helpful to identify high-risk patients with ENKL

Standard therapy regimens produce a 5-year relative survival rate of only 69%, with the critical need to increase the treatment-success rate of this patient population presenting at diagnosis with a median age of 66 years and many comorbidities. The evidence that an impaired immune system favors the development of NHL has opened the stage for new therapeutics, and specifically for the adoptive transfer of ex vivo-expanded antigen-specific T-cells. In this review, we discuss how T-cells specific for viral-associated antigens, nonviral-associated antigens expressed by the tumor, T-cells redirected through the expression of chimeric antigen receptors, and transgenic T-cell receptors against tumor cells have been developed and used in clinical trials for the treatment of patients with NHLs.

    The aim of this project was to define indications for hematopoietic stem cell transplantation in follicular lymphoma in Europe. In the absence of evidence-based data, a RAND-modified Delphi procedure was used by an expert panel. After pre-defining statements, these were individually/anonymously scored by each participant using a 9-point scale. Consensus was reached that: 1) high-dose therapy with autologous stem cell rescue is not an appropriate option to consolidate first remission in patients responding to immuno-chemotherapy outside clinical trials; 2) in patients with first chemo-sensitive relapse, high-dose therapy with autologous stem cell rescue is an appropriate option to consolidate remission, especially in patients with a short response after immuno-chemotherapy or with high-risk FLIPI; 3) high-dose therapy with autologous stem cell rescue is also appropriate in second/subsequent chemo-sensitive relapses; 4) allotransplant (preferably a reduced intensity conditioning-allotransplant) should be considered at relapse after high-dose therapy with autologous stem cell rescue. No consensus was reached on the role of high-dose therapy with autologous stem cell rescue in low-risk first relapse, or on when an allotransplant should be preferred over high-dose therapy with autologous stem cell rescue. In the absence of evidence-based data, the consensus method used was a valuable tool to define indications for hematopoietic stem cell transplant in follicular lymphoma. PMID:23813647

    Sarcopenia reportedly predicts poor outcomes in elderly patients with diffuse large B-cell lymphoma (DLBCL). However, because previous studies only involved elderly patients, it is difficult to generalize these results to all patients with DLBCL. We retrospectively analyzed 207 patients with DLBCL who received the R-CHOP or R-THP-COP regimen between June 2004 and May 2014. Sarcopenia was measured by the analysis of CT images at the L3 level before treatment. The surface of muscular tissues was selected according to the CT Hounsfield unit. This value was normalized for stature in order to calculate the L3 skeletal muscle index (L3 SMI, cm(2)/m(2)). Median age at diagnosis in the 121 males and 86 females was 67 years (range, 19-86 years). The sex-specific cutoffs for the L3 SMI were determined by receiver operator curve (ROC) analysis. Sarcopenic patients were older than non-sarcopenic patients, with a median age of 70 and 65 years, respectively (p sarcopenic and non-sarcopenic patients. With a median follow-up of 50.4 months, the 3-year overall survival (OS) was 70 % in the sarcopenic group and 85 % in the non-sarcopenic group (p = 0.0260). In a subgroup analysis by gender, there was a significant difference in the OS when comparing sarcopenic and non-sarcopenic patients in males but not in females (p = 0.0003, p = 0.4440, respectively). Sarcopenia is an independent prognostic factor in male patients with DLBCL. PMID:26385388

    Full Text Available Abstract Background The breast is a rare extranodal site of non-Hodgkin lymphoma, and primary breast lymphoma (PBL has been arbitrarily defined as disease localized to one or both breasts with or without regional lymph nodes involvement. The aim of this study was to evaluate the clinical outcomes in patients with diffuse large B cell lymphoma (DLBCL and breast involvement, and to find the criteria of PBL reflecting the outcome and prognosis. Methods We retrospectively analyzed data from 68 patients, newly diagnosed with DLBCL and breast involvement at 16 Korean institutions between January 1994 and June 2009. Results Median age at diagnosis was 48 years (range, 20-83 years. Forty-three (63.2% patients were PBL according to previous arbitrary criteria, sixteen (23.5% patients were high-intermediate to high risk of international prognostic index. The patients with one extranodal disease in the breast (OED with or without nodal disease were 49 (72.1%, and those with multiple extranodal disease (MED were 19 (27.9%. During median follow-up of 41.5 months (range, 2.4-186.0 months, estimated 5-year progression-free survival (PFS was 53.7 ± 7.6%, and overall survival (OS was 60.3 ± 7.2%. The 5-year PFS and OS was significantly higher for patients with the OED group than those with the MED group (5-year PFS, 64.9 ± 8.9% vs. 27.5 ± 11.4%, p = 0.001; 5-year OS, 74.3 ± 7.6% vs. 24.5 ± 13.0%, p Conclusions Our results show that the patients included in OED group, reflecting different treatment outcome, prognosis and pattern of progression, should be considered as PBL in the future trial. Further studies are warranted to validate our suggested criteria.

    Full Text Available A patient with mantle cell non-Hodgkin's lymphoma presented herself with fever, nausea, right upper quadrant pain on the 7th day of R-CHOP chemotherapy. After hospitalization with the suspicion of acute cholecystitis, she received antibiotherapy with G-CSF because of emerging neutropenia at the 10th day of chemotherapy. Abdominal computed tomography revealed small infarcts in the spleen and kidneys. The echymotic lesion which developed on her right lateral malleolus, became bullous in the following days and treated as ecthyma gangrenosum. Altough the patient was afebrile with a normal neutrophil count on the third day of antibiotherapy, she developed acute renal failure and deteriorated rapidly. The patient underwent hemodialysis but expired on the 10th day of hospitalization. Post mortem autopsy findings showed ischemic infarction and necrosis of parenchyma due to mycotic thrombosis of arteries and veins of many organs (heart, lung, diaphgram, kidneys, spleen, gut mucosa as well as invasion of vessel walls and parenchyma by mucor. We reviewed mucormycosis in the light of this case.

    2014-01-01

    Full Text Available Despite advances in the field, a clear treatment algorithm for most peripheral T-cell lymphoma (PTCL subtypes remains to be defined. Generating reliable randomized data for this type of pathology remains a challenge because of the relative rarity of the disease and the heterogeneity of subtypes. Newer agents, such as the class-I selective histone deacetylase inhibitor romidepsin, have demonstrated efficacy and manageable toxicity in the relapsed and refractory setting. Whether novel agents should be used in conjunction with more conventional cytotoxic therapies or in sequence with a transplant strategy is unknown at this time. Here we report the successful use of romidepsin monotherapy as a bridge to allogeneic stem cell transplantation in a patient who had previously relapsed after several lines of conventional cytotoxic therapy for PTCL. Romidepsin provided the patient with sufficient disease control to proceed to transplantation while remaining in complete remission.

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

    Recent developments in microscopy have led to superresolution microscopy images of cells. Structured illumination microscopy was used before to reveal new details in the DNA structure and the structure of the DNA-free space in the DAPI-stained cell nuclei of the Hodgkin's lymphoma HDLM-2 cell line. This study extends this technology to primary pre-treatment classical Hodgkin's lymphoma samples of ten patients. Significant differences in both the DNA structure and the structure of the DNA-free space were detected between lymphocytes and malignant cells. Both types of structures were similar for lymphocytes of different patients. When the patients were un-blinded and grouped based on their clinical outcome, either non-relapsed or relapsed, a significant difference in the DNA structure of their Reed-Sternberg (RS) cells was found. Since, RS cells develop from mono-nucleated Hodgkin (H) cells, these data suggest distinct architectural restructuring of nuclei during RS cell formation in patients going to long-lasting remission versus relapse.

  4. Characterization of lymphokine-activated killer cells from peripheral blood and lymph nodes of non-Hodgkin's lymphoma patients

    International Nuclear Information System (INIS)

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

    Only a few cases of extranodal Epstein-Barr virus (EBV)-associated B-cell lymphomas arising from patients with angioimmunoblastic T-cell lymphoma (AITL) have been described. We report a case of AITL of which secondary cutaneous EBV-associated diffuse large B-cell lymphoma (DLBCL) developed after the initial diagnosis of AITL. A 65-year-old Chinese male patient was diagnosed as AITL based on typical histological and immunohistochemical characteristics in biopsy of the enlarged right inguinal lymph nodes. The patient initially received 6 cycles of chemotherapy with CHOP regimen (cyclophosphamide, vincristine, adriamycin, prednisone), but his symptoms did not disappear. Nineteen months after initial diagnosis of AITL, the patient was hospitalized again because of multiple plaques and nodules on the skin. The skin biopsy was performed, but this time the tumor was composed of large, polymorphous population of lymphocytes with CD20 and CD79a positive on immunohistochemical staining. The tumor cells were strong positive for EBER by in situ hybridization. The findings of skin biopsy were compatible with EBV-associated DLBCL. CHOP-R chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab) was then administered, resulting in partial response of the disease with pancytopenia and suppression of cellular immunity. To our knowledge, this is the first case of cutaneous EBV-associated DLBCL originated from AITL in Chinese pepole. We suggest the patients with AITL should perform lymph node and skin biopsies regularly in the course of the disease to detect the progression of secondary lymphomas. PMID:22260632

    Purpose: To describe the MR findings of primary central nervous system T-cell lymphoma (T-PCNSL) in immunocompetent patients. Material and Methods: Seven patients with pathologically proven T-PCNSL were included in our study. The number, location, shape, enhancement pattern, and signal intensity of the tumors were determined. Diffusion-weighted images (DWI) and perfusion-weighted images (PWI) were obtained in four and two patients, respectively. Apparent diffusion coefficients (ADCs) were generated, and regions of interest were defined in each lesion. Results: Four patients with T-PCNSL had a single mass, while the others had multiple lesions (four, three, and two lesions, respectively). All seven cases of T-PCNSL had a supratentorial location: 12 in the subcortical area and 1 in the thalamus. No leptomeningeal involvement was noted. All tumors showed iso- to low T1 and iso- to slightly high T2 signal intensity to the adjacent gray matter. Rim enhancement was seen in 5 of the 7 patients (71.4%), while heterogeneous and homogeneous enhancement was seen in each of two. On DWI and ADC maps, the enhancing lesions showed slight hyperintensity in three patients (mean ADC ratio, 0.92{+-}0.06) and iso-intensity in the other (ADC ratio, 1.02{+-}0.05). Cystic areas consistent with necrosis were noted in three patients. High-signal intensity area in the cortex was noted on T1-weighted images in three patients, suggesting hemorrhage. In two patients, the same signal intensity area was noted within the mass. The two masses on the relative cerebral blood volume (rCBV) map demonstrated either similar or slightly higher signal intensity than that of the contralateral white matter. The rCBV ratios of these two masses were 1.27{+-}0.16 and 1.35{+-}0.2, respectively. Conclusion: T-PCNSLs show a predilection for a subcortical location, a relatively high incidence of cortical or intratumoral hemorrhage, rim enhancement, or cystic areas consistent with necrosis on magnetic resonance

    Full Text Available Background: Serum lactate dehydrogenase is a non-specific marker for lymphoma whose prognostic significance is well established for both indolent and aggressive lymphomas at the time of diagnosis. The performance characteristics of this enzyme in predicting relapse in patients with diffuse large B-cell lymphoma has not been well studied. Methods: This study compared serum lactate dehydrogenase levels in 27 patients with diffuse large B-cell lymphoma who relapsed after sustaining a complete response versus 87 patients who did not relapse. For relapsed patients, the serum lactate dehydrogenase level at relapse was compared with the level three months before (considered baseline. For non-relapsed patients, the last two levels during follow-up were compared. For statistical analysis the T-test was used to compare differences in mean values between groups. The sensitivity, specificity, positive and negative predictive values for serum lactate dehydrogenase in detecting relapse compared to confirmatory imaging were calculated. Results: At relapse, only 33% patients had increases in serum lactate dehydrogenase above the upper limit of normal. The mean increase was 1.2-fold above the upper limit of normal for relapsed vs. 0.83 for those who did not relapse (p-value = 0.59. The mean increase in serum lactate dehydrogenase, from baseline, was 1.1-fold in non-relapsed vs. 1.3 in relapsed patients (p-value = 0.3. The likelihood ratio of relapse was 4.65 for patients who had 1.5-fold increases in serum lactate dehydrogenase above baseline (p-value = 0.03. The sensitivity, specificity, positive and negative predictive values of 1.5-fold increases for detecting relapse, compared to clinical and imaging findings were 0.18, 0.95, 0.55, and 0.79, respectively. Conclusion: A 1.5-fold increase in serum lactate dehydrogenase, over a period of 3 months, is associated with increased likelihood of relapse from diffuse large B-cell lymphoma.

Translocations involving ALK, the anaplastic lymphoma kinase gene, are associated with a favorable clinical outcome. Such ALK-positive ALCLs are usually responsive to a multidrug chemotherapy with CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone. However, there is no general consensus on the optimal therapy for relapsed or refractory ALCL. We report the case of a 24-year-old male suffering from ALK-positive ALCL with an uncommon manifestation of only extranodal disease in the gastric cardia region that showed primary refractoriness to standard CHOP chemotherapy. A combination therapy consisting of the anti-CD30 drug conjugate, brentuximab vedotin, and classical lymphoma salvage regimen DHAP (cisplatin, high-dose cytarabine and dexamethasone was administered. Following two treatment cycles in 21-day intervals, the lymphoma showed considerable regression based on imaging diagnostics and no evidence of vital lymphoma in a subsequent biopsy. We did not observe any increase in toxicity; in particular, polyneuropathy and febrile neutropenia were not observed. In summary, we report that the antibody-drug conjugate brentuximab vedotin and a classical regimen used for aggressive lymphoma, DHAP, could be combined as salvage therapy in a case of refractory ALK-positive ALCL. Phase I/II studies will be required for safety and efficacy analysis.Keywords: anaplastic large cell lymphoma (ALCL, refractory/relapsed lymphoma, anti-CD30 drug conjugate, DHAP

    Full Text Available Purpose: To describe a series of patients with Non-Hodgkin′s lymphoma (NHL and concomitant eyelid carcinoma. Methods: In this non-comparative interventional case series, we retrospectively reviewed the medical records of 5 patients with NHL who developed eyelid carcinoma. Results: The patients included one female and four male subjects. Systemic lymphoma had been diagnosed 1 to 72 months prior to development of the eyelid carcinoma. The lesions were basal cell carcinoma in three, and squamous cell carcinoma in two cases. The lymphoma was advanced (stage III or IV in all patients. Four patients underwent surgical excision of the carcinoma and one patient was awaiting surgical treatment after completing systemic chemotherapy. Three subjects had high-grade carcinomas. Two patients had perineural invasion; one received adjuvant radiotherapy postoperatively but the other did not due to receiving systemic chemotherapy for recurrent NHL. Conclusions: Systemic lymphoma may be associated with aggressive eyelid carcinomas. Perineural invasion is frequently encountered in this situation and should be treated with adjuvant radiation therapy to decrease the likelihood of local recurrence.

    Burkitt′s lymphoma is an aggressive form of Non-Hodgkin′s lymphoma composed of malignant cells of B lymphocyte origin. Burkitt′s lymphoma is a rarity in the Indian subcontinent. Though intraoral Burkitt′s lymphoma in HIV positive individuals is very uncommon, its importance lies in the fact that it is often the first sign of the underlying immunosuppression. We present a case of Burkitt′s lymphoma in right maxillary region which was the first manifestation of HIV in the patient.

    Activated regulatory T cells (Tregs) suppress proliferation and differentiation of normal B cells. In our study, allogeneic polyclonal CD4 (+) CD25 (+) Tregs and CD4 (+) CD25 (+) CD127(lo)Tregs expanded in vitro in the presence of rapamycin and low dose IL-2 suppressed proliferation of 11 out of 12 established lymphoma B-cell lines. The effect of expanded CD4 (+) CD25 (+) Tregs on survival of freshly isolated lymphoma B cells maintained in culture with soluble multimeric CD40L and IL-4 was variable across lymphoma entities. The survival of freshly isolated follicular lymphoma cells usually decreased in cocultures with CD4 (+) CD25 (+) Tregs. Treg effect on chronic lymphocytic leukemia/small lymphocytic lymphoma cells ranged from suppression to help in individual patients. CD4 (+) CD25 (+) Tregs or CD4 (+) CD25 (+) CD127(lo)Tregs expanded ex vivo with rapamycin could be used to suppress regrowth of residual lymphoma after autologous hematopoietic cell transplantation (HCT), and to counteract both graft-versus-host disease and lymphoma re-growth after allogeneic HCT in select patients with lymphoma susceptible to the regulation by Tregs.

    To investigate CT and 1{sup 8F}-fluorodeoxyglucose (1{sup 8F}-FDG) positron-emission tomography/CT findings of primary endobronchial marginal zone B-cell lymphoma of the bronchus-associated lymphoid tissue (BALT). From June 2006 through April 2012, seven patients (six female, one male; age range, 21-61 years; mean age, 49 years) were examined who were pathologically diagnosed with the primary endobronchial marginal zone B-cell lymphoma of BALT. We evaluated the locations and characteristics of the lesions on CT and 1{sup 8F}-FDG-PET/CT scans. The lesions were classified into the following three patterns: 1) solitary intraluminal nodule; 2) several tiny nodular protrusions; and 3) diffuse wall thickening. A solitary intraluminal nodule was observed in four patients (57.1%), several tiny nodular protrusion in two patients (28.6%), and diffuse wall thickening in one patient (14.3%). The lesions were categorized into 3 major locations: confined to the trachea (n 3), confined to the lobar bronchus (n = 2), and diffuse involvement of the trachea and both main bronchi (n = 2). All lesions demonstrated homogeneous iso-attenuation as compared with muscle on pre- and post-enhancement scans. Secondary findings in the lungs (n = 3; 42.9%) included postobstructive lobar atelectasis (n = 1), air trapping (n = 1), and pneumonia (n = 1). On 1{sup 8F}-FDG-PET/CT (n = 5), 4 lesions showed homogeneous uptake with maximum standardized uptake values (mSUV), ranging 2.3-5.7 (mean mSUV: 3.3). One lesion showed little FDG uptake. Primary endobronchial marginal zone B-cell lymphoma of the BALT manifests as three distinct patterns on CT, with the solitary intraluminal nodule presenting as the main pattern. Most lesions demonstrate homogeneous but weak FDG uptake on 1{sup 8F}-FDG-PET/CT.

    We examined treatment with or without anthracyclines in 72 eldery diffuse large B-cell lymphoma patients (age ≥ 65 years) in a retrospective cohort analysis. Factors leading to treatment without an anthracycline included age and ejection fraction, whereas markers of tolerability were similar between groups. This study highlights the details of anthracycline tolerability in elderly lymphoma patients. Introduction Although diffuse large B-cell lymphoma (DLBCL) can be cured with rituximab and anthracycline-based therapy, within the elderly population there are additional factors to consider in selecting a treatment regimen including comorbid conditions, decreased drug metabolism, decreased hematologic reserve, reduced performance status, and regimen-related toxicity. Patients and Methods We performed a retrospective cohort analysis of patients with DLBCL aged ≥ 65 years at time of diagnosis treated with either an anthracycline-containing regimen (ACR; n = 59) or a non-ACR (n = 13) to assess factors that led to treatment selection, tolerability, and outcomes. Results The mean age was 73 years in the ACR and 77 years in the non-ACR group (P = .009), and median left ventricular ejection fraction (LVEF) at diagnosis was 60% in the ACR group and 45% in the non-ACR group (P < .001). With an ACR, elderly DLBCL patients had a median overall survival of 28 months and a 2-year progression-free survival (PFS) of 64%. After an ACR, 14 patients [24%] (out of 59 total patients) had a decrease in LVEF, 7 patients [15%] (% is based off of those who we had the data collected, so this is out of 45 with this specific data) required a dose reduction of the anthracycline, and 15 patients [33%] (% is based off of those who we had the data collected, so this is out of 45 with this specific data) could not complete the regimen as planned. Hospitalization due to toxicity occurred in 20 patients [44%] (% is based off of those who we had the data collected, so this is out of 45 with data

    Full Text Available Aggressive B-cell lymphoma (BCL comprises a heterogeneous group of malignancies, including diffuse large B-cell lymphoma (DLBCL, Burkitt lymphoma, and mantle cell lymphoma (MCL. DLBCL, with its 3 subtypes, is the most common type of lymphoma. Advances in chemoimmunotherapy have substantially improved disease control. However, depending on the subtype, patients with DLBCL still exhibit substantially different survival rates. In MCL, a mature B-cell lymphoma, the addition of rituximab to conventional chemotherapy regimens has increased response rates, but not survival. Burkitt lymphoma, the most aggressive BCL, is characterized by a high proliferative index and requires more intensive chemotherapy regimens than DLBCL. Hence, there is a need for more effective therapies for all three diseases. Increased understanding of the molecular features of aggressive BCL has led to the development of a range of novel therapies, many of which target the tumor in a tailored manner and are summarized in this paper.

    Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease defined by transcriptional classifications, specific signaling and survival pathways, and multiple low-frequency genetic alterations. Preclinical model systems that capture the genetic and functional heterogeneity of DLBCL are urgently needed. Here, we generated and characterized a panel of large B-cell lymphoma (LBCL) patient-derived xenograft (PDX) models, including 8 that reflect the immunophenotypic, transcriptional, genetic, and functional heterogeneity of primary DLBCL and 1 that is a plasmablastic lymphoma. All LBCL PDX models were subjected to whole-transcriptome sequencing to classify cell of origin and consensus clustering classification (CCC) subtypes. Mutations and chromosomal rearrangements were evaluated by whole-exome sequencing with an extended bait set. Six of the 8 DLBCL models were activated B-cell (ABC)-type tumors that exhibited ABC-associated mutations such as MYD88, CD79B, CARD11, and PIM1. The remaining 2 DLBCL models were germinal B-cell type, with characteristic alterations of GNA13, CREBBP, and EZH2, and chromosomal translocations involving IgH and either BCL2 or MYC Only 25% of the DLBCL PDX models harbored inactivating TP53 mutations, whereas 75% exhibited copy number alterations of TP53 or its upstream modifier, CDKN2A, consistent with the reported incidence and type of p53 pathway alterations in primary DLBCL. By CCC criteria, 6 of 8 DLBCL PDX models were B-cell receptor (BCR)-type tumors that exhibited selective surface immunoglobulin expression and sensitivity to entospletinib, a recently developed spleen tyrosine kinase inhibitor. In summary, we have established and characterized faithful PDX models of DLBCL and demonstrated their usefulness in functional analyses of proximal BCR pathway inhibition. PMID:26773040

    Characterization of tumors at the molecular level has improved our knowledge of cancer causation and progression. Proteomic analysis of their signaling pathways promises to enhance our understanding of cancer aberrations at the functional level, but this requires accurate and robust tools. Here, we develop a state of the art quantitative mass spectrometric pipeline to characterize formalin-fixed paraffin-embedded tissues of patients with closely related subtypes of diffuse large B-cell lymphoma. We combined a super-SILAC approach with label-free quantification (hybrid LFQ) to address situations where the protein is absent in the super-SILAC standard but present in the patient samples. Shotgun proteomic analysis on a quadrupole Orbitrap quantified almost 9,000 tumor proteins in 20 patients. The quantitative accuracy of our approach allowed the segregation of diffuse large B-cell lymphoma patients according to their cell of origin using both their global protein expression patterns and the 55-protein signature obtained previously from patient-derived cell lines (Deeb, S. J., D'Souza, R. C., Cox, J., Schmidt-Supprian, M., and Mann, M. (2012) Mol. Cell. Proteomics 11, 77-89). Expression levels of individual segregation-driving proteins as well as categories such as extracellular matrix proteins behaved consistently with known trends between the subtypes. We used machine learning (support vector machines) to extract candidate proteins with the highest segregating power. A panel of four proteins (PALD1, MME, TNFAIP8, and TBC1D4) is predicted to classify patients with low error rates. Highly ranked proteins from the support vector analysis revealed differential expression of core signaling molecules between the subtypes, elucidating aspects of their pathobiology. PMID:26311899

    Full Text Available Abstract Only a few cases of extranodal Epstein-Barr virus (EBV-associated B-cell lymphomas arising from patients with angioimmunoblastic T-cell lymphoma (AITL have been described. We report a case of AITL of which secondary cutaneous EBV-associated diffuse large B-cell lymphoma (DLBCL developed after the initial diagnosis of AITL. A 65-year-old Chinese male patient was diagnosed as AITL based on typical histological and immunohistochemical characteristics in biopsy of the enlarged right inguinal lymph nodes. The patient initially received 6 cycles of chemotherapy with CHOP regimen (cyclophosphamide, vincristine, adriamycin, prednisone, but his symptoms did not disappear. Nineteen months after initial diagnosis of AITL, the patient was hospitalized again because of multiple plaques and nodules on the skin. The skin biopsy was performed, but this time the tumor was composed of large, polymorphous population of lymphocytes with CD20 and CD79a positive on immunohistochemical staining. The tumor cells were strong positive for EBER by in situ hybridization. The findings of skin biopsy were compatible with EBV-associated DLBCL. CHOP-R chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab was then administered, resulting in partial response of the disease with pancytopenia and suppression of cellular immunity. To our knowledge, this is the first case of cutaneous EBV-associated DLBCL originated from AITL in Chinese pepole. We suggest the patients with AITL should perform lymph node and skin biopsies regularly in the course of the disease to detect the progression of secondary lymphomas.

  9. Racial differences in treatment and survival in older patients with diffuse large B-cell lymphoma (DLBCL)

    International Nuclear Information System (INIS)

    Diffuse large B-cell lymphoma (DLBCL) comprises 31% of lymphomas in the United States. Although it is an aggressive type of lymphoma, 40% to 50% of patients are cured with treatment. The study objectives were to identify patient factors associated with treatment and survival in DLBCL. Using Surveillance, Epidemiology, and End Results (SEER) registry data linked to Medicare claims, we identified 7,048 patients diagnosed with DLBCL between January 1, 2001 and December 31, 2005. Patients were followed from diagnosis until the end of their claims history (maximum December 31, 2007) or death. Medicare claims were used to characterize the first infused chemo-immunotherapy (C-I therapy) regimen and to identify radiation. Multivariate analyses were performed to identify patient demographic, socioeconomic, and clinical factors associated with treatment and with survival. Outcomes variables in the survival analysis were all-cause mortality, non-Hodgkin's lymphoma (NHL) mortality, and other/unknown cause mortality. Overall, 84% (n = 5,887) received C-I therapy or radiation treatment during the observation period: both, 26%; C-I therapy alone, 53%; and radiation alone, 5%. Median age at diagnosis was 77 years, 54% were female, 88% were white, and 43% had Stage III or IV disease at diagnosis. The median time to first treatment was 42 days, and 92% of these patients had received their first treatment by day 180 following diagnosis. In multivariate analysis, the treatment rate was significantly lower among patients ≥ 80 years old, blacks versus whites, those living in a census tract with ≥ 12% poverty, and extra-nodal disease. Blacks had a lower treatment rate overall (Hazard Ratio [HR] 0.77; P < 0.001), and were less likely to receive treatment within 180 days of diagnosis (Odds Ratio [OR] 0.63; P = 0.002) than whites. In multivariate survival analysis, black race was associated with higher all-cause mortality (HR 1.24; P = 0.01) and other/unknown cause mortality (HR 1

    Full Text Available Diffuse large B-cell lymphoma is the most common form of lymphoma. It usually begins in the lymph nodes; up to 40% may have an extranodal presentation. According to a definition of primary extranodal lymphoma with presentation only in extranodal sites, there are reports of large B-cell lymphomas limited to liver or spleen as separate entities, and to date there have been only three documented cases of primary hepatosplenic presentation. This paper reports a fourth case. Due to a review of the literature and the clinical course of the case reported, we conclude that primary hepatosplenic large B-cell lymphoma has been found predominantly in females older than 60 years. The patients reported had <2 months of evolution prior to diagnosis, prominent B symptoms, splenomegaly in three and hepatomegaly in two, none with lymph node involvement. All had thrombocytopenia and abnormal liver function tests; three had anemia and elevated serum lactic dehydrogenase levels, two with hemophagocytosis in bone marrow. Because of the previously mentioned data, it can be stated that primary hepatosplenic lymphoma is an uncommon and aggressive form of disease that requires immediate recognition and treatment.

  11. Radioimmunotherapy with Y-90-epratuzumab in patients with previously treated B-cell lymphoma. A fractionated dose-escalation study

    International Nuclear Information System (INIS)

    Aim: Fractionated RIT may improve outcome by decreasing heterogeneity in absorbed dose and by increasing therapeutic window. The humanised anti-CD22 antibody, Epratuzumab, (Immunomedics, Inc., Morris Plains, NJ) can be given repeatedly with minimal risk of neutralising Ab (HAHA), making fractionated treatment with 90Y-labelled epratuzumab possible. Materials and Methods: Patients with previously treated B-cell lymphoma received increasing number (2-4) of weekly infusions of 90Y-epratuzumab. Patients received either 185 MBq/m2 per infusion (group A), or, if they had a history of high-dose chemotherapy with stem-cell rescue, 92.5 MBq/m2 per infusion (group B). The first infusion included 150 MBq of 111Indium for scintigraphic verification of tumour targeting and dosimetry. 1.5 mg/kg epratuzumab was administered with each infusion. The treatment could be repeated once after 3 m. Results: Of 23 patients, 16 in group A and 6 in group B were evaluable for response. The RR in group A was 62% objective response (OR) and 25% CR/CRu. One patient in group B showed OR. OR was seen in aggressive and indolent lymphoma. Response was also long-lasting and event-free survival of patients showing CR/CRu was 14 to 25+ months. In group A all seven patient, receiving three infusions, showed less than grade 3 platelet and neutrophil toxicity, except for two patients suffering grade 3 neutropenia. Of five patients with 4 weekly infusions there were two patients with dose-limiting haematological toxicity (DLT), both recently treated with high dose cytosar before RIT. With criteria used the maximal tolerated dose was three infusions 185 MBq/m2. In group B no patient suffered DLT and one patient exhibited OR. Seven patients were retreated after 3 months with minor toxicity, but improvement in OR in two cases. No patient has developed HAHA. CD22 expression on tumour cells, as assessed by flow cytometry, is available in 18 of 22 patients. In group A, seven of eight patients with unequivocal

    Treatment with cyclophosphamide, doxorubicin, vincristine and prednisolone (CHOP) has been considered as the standard therapy for diffuse large B-cell lymphoma (DLBCL) for more than 20 years. CHOP treatment in combination with targeted immunotherapy, rituximab (R-CHOP), resulted in significant improvements in the treatment of this group of patients. In this study, efficacy of R-CHOP and R-CHOP-like treatments was analysed. Results were compared to the data of historical patients only receiving CHOP treatment or CHOP-like treatment. Between September 2002 and April 2005, 140 newly diagnosed, untreated DLBCL patients started to receive R-CHOP treatment in a single centre. The eligibility criteria included advanced stage (clinical stages III-IV), or large tumour size (>7 cm) and/or symptom B or extranodal manifestation in the case of clinical stages I-II. The results were compared to the data of 130 patients only receiving CHOP treatment in the past. In the patients receiving R-CHOP, the therapeutic outcomes were superior for all parameters. During an average follow-up period of 44 or 52 months, the overall remission rate was 73.6% in the R-CHOP group in comparison with 47.7% in the CHOP group. The 5-year overall survival was 68.6% vs. 41.0% (RR: 0.4293, CI: 0.2963-0.6221; p < 0.0001), the event-free survival was 59.8% vs. 33.5% (RR: 0.5038, CI: 0.3606-0.7038; p < 0.0001) and the progression-free survival was 64.4% vs. 37.6% (RR: 0.4915, CI: 0.3442-0.7019; p < 0.0001). Since prognostic parameters were more favourable in the R-CHOP group, patient groups were also compared using the International Prognostic Index score. Again, significant differences were revealed by the subgroup analyses. The 5-year overall survival was 74.4% vs. 47.9% (RR: 0.4475, CI: 0.2418-0.8285; p = 0.0084) and 52.0% vs. 28.8% (RR: 0.4989, CI: 0.3098-0.8035; p = 0.003) in the group with good prognosis and in the group with poor prognosis, respectively. In the group with very good prognosis, the

    Primary systemic anaplastic large cell lymphoma (ALCL) is divided into two entities according to the expression of anaplastic lymphoma kinase (ALK). We investigated {sup 18}F-fluorodeoxyglucose positron emission tomography ({sup 18}F-FDG PET) findings in primary systemic ALCL according to ALK expression. Thirty-seven patients who had baseline PET before CHOP (cyclophosphamide, doxorubicin, vincristine and prednisolone)-based chemotherapy were enrolled. Among them, patients who underwent interim and/or post-therapy PET were further investigated for the treatment response and survival analysis. Baseline PET was analyzed visually and semi-quantitatively using peak SUV, and interim and post-therapy PETs were visually analyzed. All cases were {sup 18}F-FDG-avid on baseline PET. The peak SUV of ALK-positive ALCL (n =16, 18.7±10.5) was higher than that of ALK-negative ALCL (n =21, 10.0±4.9) (P =0.006). In ALK-negative ALCL, complete response (CR) rate in negative-interim PET was higher than positive-interim PET (100 % vs 37.5 %, P=0.02); however, there was no such difference in ALK-positive ALCL (100 % vs 75 %, P =0.19). The 3-year progression-free survival (PFS) was not significantly different between ALK-positive and ALK-negative ALCL (72.7 % vs 47.6 %, P =0.34). In ALK-negative ALCL, negative interim and post-therapy PET patients had better 3-year PFS than positive interim (83.3 % vs 25.0 %, P =0.06) and post-therapy PET patients (70.0%vs 20.0 %, P =0.04). In contrast, ALK-positive ALCL had no such differences between PFS and PET results. On baseline PET, all cases showed {sup 18}F-FDG avidity, and ALK expression was related to higher {sup 18}F-FDG uptake. ALK-positive patients tend to have better PFS than ALK-negative patients. Negative-interim PET was a good indicator of CR, and interim or post-therapy PET was helpful for predicting the prognosis only in the ALK-negative group.

However, the minimal numbers of both circulating HPCs and CD34+ cells required for performing an efficient hematopoietic stem cell (HSC harvest in lymphoma and myeloma patients have not been defined in our institution. Patients and methods: Medical records of 50 lymphoma and myeloma patients undergoing peripheral blood HSC harvest in our institution were retrospectively reviewed. The minimal and optimal HSC harvest yield required for the treatment was considered to be ≥2×106 CD34+ cells/kg and ≥5×106 CD34+ cells/kg, respectively. Results: The minimally required or optimal HSC yield obtained was not influenced by age (≥60 years, sex, underlying malignancies, disease status, multiple rounds of chemotherapy, or history of radiotherapy. The numbers of both circulating HPC and CD34+ cell were higher in patients with minimally required HSC yields (P=0.000 for HPC and P=0.000 for CD34+ cell and also in patients with optimal HSC yields (P=0.011 for HPC and P=0.006 for CD34+ cell.

    Aim: To investigate the pharmacodynamic and pharmacokinetic parameters of pegylated liposomal doxorubicin (PLD) combined with cyclophosphamide, vincristine, and prednisolone in patients with peripheral T-cell lymphomas (PTCL).Methods: Seven chemonaive patients and four patients with relapsed peripheral T-cell lymphomas were treated with a CCOP regimen consisting of an intravenous administration of cyclophosphamide (750 mg/m2), vincristine (1.4 mg/m2), and PLD (30 mg/m2) on d 1,as well as an oral administration of prednisolone (60 mg/m2)on d 1-5. This regimen was repeated every 3 weeks for six cycles, and the clinical response and toxicity of the regimen were monitored. In addition, the plasma concentration of PLD at different time points was determined before and after treatment. The pharmacokinetics (PKs) software was used to estimate the pharmacokinetic parameters of PLD.Results: The 11 PTCL patients received 35 treatment cycles. Three of them achieved complete response (CR), two partial response (PR), four stable disease (SD), and two progressive disease (PD). The overall response rate (ORR) was 45.5%, and the CR rate was 27.3%. In the 7 chemonaive patients, three achieved CR, two PR, one SD, and one PD. The ORR was 71.4%, and CR rate was 42.9%.The median follow-up time was 15 months, but 6 out of 11 patients were dead at the time of data analysis. The 1-year overall survival rate was 45.5%, and the median progression-free survival (PFS) rate was 6.5 [95% confidence interval (95% Cl) 3.17-19.02] with a survival rate of 11.5 months (95% Cl 6.65-16.36). The main toxicity was myelosuppression. Oral mucositis and hand-foot syndrome 3.56 L/m2, respectively.Conclusion: The CCOP regimen was effective and well tolerated in patients with peripheral T-cell lymphomas. The results of the pharmacokinetic parameters showed that PLD had long retention time in blood circulation.

  3. The mantle cells lymphoma: a proposed treatment

    International Nuclear Information System (INIS)

    A literature review was performed on mantle cells lymphoma in the therapeutic schemes. The literature that has been used is published in journals of medicine specializing in hematology, oncology, radiation therapy, molecular biology and internal medicine. The literature review was performed to propose a scheme of treatment according to Costa Rica. Epigenetic alterations have been revealed in patients with mantle lymphoma on current researches. The mantle lymphoma pathology has been described in various forms of clinical and histological presentation, stressing the importance of detailing the different methods and diagnostic reports. Working groups have proposed and developed various chemotherapy regimens and concluded that CHOP alone is without effect in mantle cell lymphoma unlike R-hyper-CVAD, CHOP / DHAP, high-dose Ara-C. Researchers have tried to develop new treatments based vaccines, use of modified viruses, specific monoclonal antibodies. The classic treatment has been triple intrathecal therapy. The central nervous system has been one of the most momentous sites of mantle cell lymphoma infiltration because poorer patient prognosis

    International Nuclear Information System (INIS)

    Purpose: This study aims to evaluate the outcome and pattern of failure in a large cohort of patients with Stage I NK/T-cell lymphoma of the upper aerodigestive tract treated with radiotherapy alone. Methods and Materials: The pathological diagnosis was confirmed using standard criteria. All patients were treated with high-dose extended-field radiotherapy alone. The median dose was 50 Gy. The primary tumor was located in the nasal cavity (n = 80), Waldeyer ring (n = 5), or oral cavity (n = 2). Results: The overall response to radiotherapy was achieved in 85 of 87 (97.7%) patients, with a complete response rate of 95.4% and a partial response rate of 2.3%. The 5-year overall survival, progression-free survival, and local control rates for all patients were 80%, 69%, and 93%, respectively. Twenty patients (23%) had disease progression or relapse. Of these, 15 patients (17%) developed systemic extranodal disseminations, whereas only 4 (5%) patients had local relapse and 4 (5%) patients had lymph node relapse. Conclusions: Our study suggests that high-dose extended-field radiotherapy alone is a curative therapy and shows favorable clinical outcome in patients with Stage I disease. With the high possibility of local control and primary failure of systemic dissemination, the integration of optimal radiotherapy with more effective systematic therapy is warranted to bring additional improvement to the outcome for these patients.

    Alectinib, a novel alternative anaplastic lymphoma kinase (ALK) inhibitor, is highly effective against ALK-positive non-small cell lung cancer (NSCLC) and is well tolerated. Molecular targeted agents generally have little contribution to alopecia. We encountered a case of alopecia that developed gradually over 2 months after initiation of alectinib administration for the treatment of ALK-positive NSCLC. The patient had no history of alopecia in previous treatments of cisplatin + pemetrexed and crizotinib. The present case indicates that alopecia should be taken into consideration as toxicity during alectinib treatment, which could adversely affect the psychological and emotional condition and quality of life even in patients treated with specific molecular targeted agents.

    2016-06-01

    Patients diagnosed with non-Burkitt high-grade B cell non-Hodgkin lymphomas demonstrating rearrangement in MYC, an oncogene promoting cellular proliferation, frequently do not achieve long-term disease-free survival due to a suboptimal response to standard front-line and salvage therapies. Double-hit lymphomas, harboring rearrangements in MYC as well as BCL2 and/or BCL6, appear to carry a particularly poor prognosis, although patients with this disease appear to achieve better survival outcomes when treated with intensified chemotherapy. Increased expression of MYC protein by immunohistochemistry as well as increased copy number or amplification of MYC may also be adverse pathologic features of non-Burkitt high-grade B cell non-Hodgkin lymphomas, although the benefit of treating these patients with intensified as opposed to standard dose chemotherapy remains unclear. Recognition and proper management of patients with MYC-altered lymphomas is crucial to improving patient outcomes. PMID:26983958

The patient, a 71 year-old woman, was previously healthy with the exception of taking verapamil for paroxysmal supraventricular tachycardia. She had presented with pyrexia and gradually progressive anemia. Brain magnetic resonance imaging revealed an infarct-like lesion in the pons, although no paralysis was observed. She was diagnosed with IVLBCL on the basis of random skin biopsy. After eight cycles of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone therapy, abnormal laboratory data had normalized, and no pontine lesion was evident on magnetic resonance imaging without receiving any intrathecal chemotherapy. IVLBCL is associated with poor prognosis, particularly in patients with central nervous system involvement. Early initiation of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone therapy and drug interactions between anticancer agents and verapamil as a p-glycoprotein inhibitor were considered the possible reasons for favorable outcome in the present case.

    Primary cutaneous T- and B-cell lymphomas are a heterogeneous group of diseases with varied clinical presentations and prognosis. The use of new molecular, histological, and clinical criteria has improved their recognition. Cutaneous B-cell and T-cell lymphomas are seldom found together in the same patient. Here we report a rare case of mycosis fungoides variant of a cutaneous T-cell lymphoma (CTCL) which later developed Epstein-Barr virus (EBV) associated cutaneous B-cell lymphoproliferative disorder. The patient initially presented with generalized erythroderma, extensive plaques, and axillary lymphadenopathy. Histopathology and immunophenotyping of her tumor from the right breast nodule revealed a T-cell lymphoma consistent with mycosis fungoides. She was initially treated with pentostatin, followed by topical mechlorethamine and topical steroids. After progression of her mycosis fungoides with worsening diffuse skin lesions on this regimen, her treatments were changed to oral bexarotene with an initial partial response followed by stable disease. Three years from her initial presentation, she developed ulcerated cauliflower-like nodules on her forehead. Biopsy of these lesions revealed EBV-positive large- and medium-sized pleomorphic B-cells consistent with EBV-driven B-cell lymphoproliferative disorder. She was treated with topical acyclovir cream on the involved skin areas while continuing with oral bexarotene for mycosis fungoides. Skin lesions gradually diminished and totally disappeared after four weeks of topical acyclovir treatment. Bexarotene treatment was continued for another year until the mycosis fungoides progressed and became wide spread causing her death four and a half years after the initial diagnosis. The coexistence of two cutaneous non-Hodgkin lymphomas of different lineage in the same patient and the complete clinical response of EBV-related B-cell cutaneous component to topical acyclovir makes this rare case particularly interesting.

    The prognosis of T-cell lymphoma (TCL) has been shown to be associated with the clinical characteristics of patients.However,there is little knowledge of whether genetic variations also affect the prognosis of TCL.This study investigated the associations between single nucleotide polymorphisms (SNPs) in tumor necrosis factor receptor superfamily (TNFRSF) genes and the survival of patients with TCL.A total of 38tag SNPs in 18 TNFRSF genes were genotyped using Sequenom platform in 150 patients with TCL.Kaplan-Meier survival estimates were plotted and significance was assessed using log-rank tests.Cox proportional hazard models were used to analyze each of these 38 SNPs with adjustment for covariates that might influence patient survival,including sex and international prognostic Index score.Hazard ratios (HRs) and their 95% confidence intervals (Cls) were calculated.Among the 38 SNPs tested,3 were significantly associated with the survival of patients with TCL.These SNPs were located at LTβR (rs3759333C>T) and TNFRSF17 (rs2017662C >T and rs2071336C>T).The 5-year survival rates were significantly different among patients carrying different genotypes and the HRs for death between the different genotypes ranged from 0.45 to 2.46.These findings suggest that the SNPs in TNFRSF genes might be important determinants for the survival of TCL patients.

    We enrolled 18 patients affected by refractory or relapsed lymphoma (HD, NHL) in a two-step protocol that included salvage chemotherapy with mitoxantrone, carboplatinum, methylprednisolone, and cytosine arabinoside (MiCMA) plus G-CSF (5 micrograms/kg/day), peripheral blood progenitor cell (PBPC) collection, and subsequent transplantation after BUCY2 regimen. After MiCMA chemotherapy, four patients (22%) achieved complete response, eight patients (44%) obtained a partial response, and six showed progression of disease (PD). Fourteen out of 18 patients (78%) were considered eligible for PBPC transplantation. Three patients with complete response refused PBPCT; they are currently in continuous complete remission (CCR) at 15, 13, and 15 months, respectively. One patient has been recently transplanted but is too early to be evaluated. Ten patients so far completed the study, eight of whom are currently alive in CR, with a median follow-up of 7.5 months (range 2-13). Hematologic reconstitution was very rapid with a median time to achieve WBC > 1 x 10(9)/L, PMN > 0.5 x 10(9)/L, platelets > 50 x 10(9)/L and > 100 x 10(9)/L of 13 (range 9-15), 12 (range 9-14), 10 (range 0-22), and 14 (range 5-49) days, respectively. Our protocol is highly effective as a salvage treatment, while permitting PBPC collection after G-CSF administration. Hemopoietic reconstitution after transplantation of PBPCs collected with this procedure is complete, rapid, and sustained. PMID:7514355

    Full Text Available In glomerular diseases, the occurence of lymphoma is mostly observed in the form of both minimal change disease and Hodgkin’s lymphoma. The coocurrence of Membranous nephropathy and membranoproliferative glomerulonephritis are generally associated with non-Hodgkin’s lymphoma. While Ig A nephropathy-lymphoma association is rare, it is generally observed in the form of non- Hodgkin’s lymphoma, and there are also cases proposed the cooccurence of Ig A nephropathy and cutaneous T-cell lymphoma. In this case, it is emphasized that IgA nephropathy presented with cresentric glomerulonephritis should be considered in patients with hodgkin’s lymphoma who have sudden renal disorder.

EATL most commonly presents in the sixth and seventh decades of life. We report a unique case of type I EATL in the colon with liver metastasis, which was presented with nonspecific radiological findings and at a very young age (29 years old compared with previously published data. We suggest that EATL should be regarded as part of differential diagnosis in any patient presenting with abdominal pain, diarrhea, weight loss, and malabsorption because delay in treatment can result in an irreversible clinical outcome.

  4. Chronic γ-irradiation results in increased cell killing and chromosomal aberration with specific breakpoints in fibroblast cell strains derived from non-Hodgkin's lymphoma patients

    International Nuclear Information System (INIS)

    Cultured skin fibroblast cells from 16 NHL (non-Hodgkin's lymphoma) patients and 2 clinically normal subjects were compared for cell survival and chromosomal aberration after chronic γ-irradiation. Fibroblasts from an ataxia telangiectasia (AT) homozygote and an AT heterozygote were used as positive controls. Following irradiation, fibroblasts from all 16 NHL patients showed an increase in both cell death and chromosomal aberration (breaks and rearrangements) compared to normal subjects. The difference in frequency of chromosomal aberration between normals and NHL-patients remained virtually unchanged over a period of 24-72 h post irradiation incubation of cells. Cell cycle analysis by flow cytometry carried out in 1 normal and 1 NHL fibroblast cell strain showed that more cells representing the NHL patient were in G2/M phase compared to the normal at various times of cytogenetic analysis. While the AT homozygote appeared to be the most radiosensitive, the AT heterozygote showed a slightly higher incidence of cell death and chromosomal aberration than the normals. The cellular and chromosomal radiosensitivity of fibroblast cell lines from NHL-patients differed slightly from that of AT heterozygote but clearly occupied an intermediate position between the AT homozygote and the normal subjects. Cells from 3 of the NHL patients showed radiation-induced specific chromosomal breaks involving chromosomes 1, 2, 6, 8, 10 and 11 which correspond to known fragile sites. Such breakpoints associated with increased radiosensitivity may be indicative of predisposition to malignancy in the patients studied. (author). 30 refs., 2 figs., 4 tabs

    Interim 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (I-PET/CT) is a powerful tool for monitoring the response to therapy in diffuse large B-cell lymphoma (DLBCL). This retrospective study aimed to determine when and how to use I-PET/CT in DLBCL. A total of 197 patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) were enrolled between October 2005 and July 2011; PET/CT was performed at the time of diagnosis (PET/CT0), after 2 and 4 cycles of chemotherapy (PET/CT2 and PET/CT4, respectively), and at the end of treatment (F-PET/CT). According to the International Harmonization Project for Response Criteria in Lymphoma, 110 patients had negative PET/CT2 scans, and 87 had positive PET/CT2 scans. The PET/CT2-negative patients had significantly higher 3-year progression-free survival rate (75.8% vs. 38.2%) and 3-year overal survival rate (93.5%vs. 55.6%) than PET/CT2-positive patients. Al PET/CT2-negative patients remained negative at PET/CT4, but 3 were positive at F-PET/CT. Among the 87 PET/CT2-positive patients, 57 remained positive at F-PET/CT, and 32 progressed during chemotherapy (15 at PET/CT4 and 17 at F-PET/CT). Comparing PET/CT4 with PET/CT0, 7 patients exhibited progression, and 8 achieved partial remission. Comparing F-PET/CT with PET/CT0, 10 patients exhibited progression, and 7 achieved partial remission. In conclusion, our results indicate that I-PET/CT should be performed after 2 rather than 4 cycles of immunochemotherapy in DLBCL patients. There is a limited role for subsequent PET/CT in the detection of relapse in PET/CT2-negative patients, but repeat PET/CT is required if the PET/CT2 findings are positive.

    Abstract Allogeneic stem cell transplant (allo-SCT) is considered a clinical option for patients with Hodgkin lymphoma (HL) who have experienced at least two chemosensitive relapses. The aim of this systematic review was to determine the benefits and harms of allo-SCT with an unrelated donor (UD) versus related donor (RD) allo-SCT for adult patients with HL. Alternative donor sources such as haploidentical donor cells (Haplo) and umbilical cord blood (UCB) were also included. The available evidence was limited. Ten studies were included in this assessment. Four studies provided sufficient data to compare UD with RD allo-SCT. None of these studies was a randomized controlled trial. Additionally, three non-comparative studies, such as registry analyses, which considered patients with UD transplants were included. The risk of bias in the studies was high. Results on overall and progression-free survival (PFS) showed no consistent tendency in favor of a donor type. Results on therapy-associated mortality and acute (grade II-IV) and chronic graft-versus-host disease were also inconsistent. The study comparing UCB with RD transplants and two non-comparative studies with UCB transplants showed similar results. One of the studies comparing additionally Haplo with RD transplants indicated a benefit in PFS for the Haplo transplant group. In summary, our findings do not indicate a substantial outcome disadvantage of UD and alternative donor sources versus RD allo-SCT for adult patients with advanced HL. PMID:23656201

    A dose modified ifosfamide, epirubicin, and etoposide (IVE) regimen was prospectively assessed for its efficacy in mobilizing peripheral blood stem cells for autologous transplantation. Two patients with Hodgkin's lymphoma and two with non-Hodgkin's lymphoma who were undergoing stem cell therapy were studied. All patients had a history of multiple treatments with insufficient stem cell mobilization. The dose modified IVE regimen consisted of ifosfamide 3 g/m(2) intravenously (IV) administered on days 1-2 in combination with epirubicin 50 mg/m(2) IV on day 1 and etoposide 200 mg/m(2) (100 mg/m(2) in two patients with complete remission) IV on days 1-3. The ifosfamide dosage was reduced to two-thirds of the original protocol. A substantial high yield of CD34(+) cells was achieved when patients were treated with a dose-modified IVE regimen, compared with that during the previous regimen (two with the ifosfamide, carboplatin, and etoposide [ICE] regimen, one with high-dose cyclophosphamide and one with the original IVE regimen). Two patients who had refractory and residual disease received a 200 mg/m(2) dose of etoposide, which resulted in tumor reduction (one patient with complete remission and one with further reduction in tumor size). After the IVE regimen, all four patients had a sufficient yield of CD34(+) cells in total, which was available for stem cell transplantation. Hematological and non-hematological toxicities were comparable in all regimens. This single-center prospective study demonstrated that the dose-modified IVE regimen can be used as a safe treatment with high mobilizing efficacy in heavily pretreated lymphoma patients.

    Full Text Available B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma (DLBCL and classical Burkitt's lymphoma (BL, is a diagnostic provisional category in the World Health Organization 2008 classification of lymphomas. This category was designed as a measure to accommodate borderline cases that cannot be reliably classified into a single distinct disease entity after all available morphological, immunophenotypical and molecular studies have been performed. Typically, these cases share features intermediate between DLBCL and classical BL or include characteristics of both lymphomas. The rarity of such cases poses a tremendous challenge to both pathologists and oncologists because its differential diagnosis has direct implications for management strategies. In this article, we present a “classical unclassifiable lymphoma with features intermediate between DLBCL and BL” in a young male patient and review of literature.

    Purpose: to analyze the influence of radiotherapy doses, chemotherapy doses, and clinical parameters on in-field disease control to assess the optimal radiation doses for treatment of non-Hodgkin's lymphoma according to the newly proposed WHO classification. Patients and methods: subjects consisted of 35 extranodal marginal-zone B-cell lymphomas of mucosa-associated lymphoid tissue (MALT) type, 75 diffuse large B-cell lymphomas (DLBCL), 14 follicular lymphomas, 17 extranodal natural killer (NK)/T-cell lymphomas, nasal type, eight unclassified peripheral T-cell lymphomas, four anaplastic large-cell lymphomas, T/null cell type, and five others. 59 patients received radiotherapy alone. 98 patients received CHOP, modified CHOP, or more intensive chemotherapy, and six patients were treated with other combination. Results: no patients with MALT lymphoma had in-field local recurrence. There were no recurrences in DLBCL patients who received chemotherapy in which the doses of adriamycin were > 200 mg/m{sup 2}, nor in DLBCL patients who were treated with > 45 Gy. Only nine of 15 patients with T-cell lymphoma treated with {<=} 50 Gy and three of five patients treated with > 50 Gy had local control. The dose of adriamycin had no influence on local control of T-cell lymphoma. Conclusion: T/NK-cell lymphomas were more radioresistant than B-cell lymphomas. The prognosis for peripheral T/NK-cell lymphomas is poor even when treated by irradiation combined with chemotherapy. (orig.)

    Follicular lymphoma (FL) is an indolent disease but transforms in 2% to 3% of patients per year into aggressive, large cell lymphoma, a critical event in the course of the disease associated with increased lymphoma-related mortality. Early transformation cannot be accurately predicted at the time of FL diagnosis and the biology of transformed FL (TFL) is poorly understood. Here, we assembled a cohort of 126 diagnostic FL specimens including 40 patients experiencing transformation (transformation for at least 5 years. In addition, we assembled an overlapping cohort of 155 TFL patients, including 114 cases for which paired samples were available, and assessed temporal changes of routinely available biomarkers, outcome after transformation, as well as molecular subtypes of TFL. We report that the expression of IRF4 is an independent predictor of early transformation (Hazard ratio, 13.3; P transformation predicts favorable prognosis. Moreover, applying the Lymph2Cx digital gene expression assay for diffuse large B-cell lymphoma (DLBCL) cell-of-origin determination to 110 patients with DLBCL-like TFL, we demonstrate that TFL is of the germinal-center B-cell-like subtype in the majority of cases (80%) but that a significant proportion of cases is of the activated B-cell-like (ABC) subtype (16%). These latter cases are commonly negative for BCL2 translocation and arise preferentially from BCL2 translocation-negative and/or IRF4-expressing FLs. Our study demonstrates the existence of molecular heterogeneity in TFL as well as its relationship to the antecedent FL. PMID:26307535

    Full Text Available The prognostic value of CD30 expression in diffuse large B-cell lymphoma (DLBCLremains controversial. Herein, we performed this retrospective study to investigate the clinical and prognostic significance of CD30 expression in patients with DLBCL.Among all the 146 patients, the expression of CD30 was observed in 23 cases (15.7%.The DLBCL patients with CD30 expression showed more likely to present B symptoms, bone marrow involvement, non-germinal centre B-cell-like (Non-GCB DLBCL, BCL-2 and Ki-67 overexpression (p<0.05. Patients with CD30 expression showed significantly poor overall and event-free survival compared with CD30 negative patients(p = 0.031 and 0.041, respectively, especially those with the high intermediate/high-risk international prognostic index (IPI(p = 0.001 and 0.007, respectively. The prognostic value of CD30 expression retained in DLBCL patients treated with either CHOP (cyclophosphamide, doxorubicin, vincristine,prednisone or R-CHOP(rituximab+CHOP. The multivariate analysis revealed that the expression of CD30 remained an unfavorable factor for both overall and event-free survival (p = 0.001 and 0.002, respectively. In conclusion, these data suggest that CD30 is expressed predominantly in Non-GCBDLBCL. The expression of CD30 implied poor outcome in DLBCL patients treated with either CHOP or R-CHOP, especially those with the high intermediate/high-risk IPI, possibly indicating that anti-CD30 monoclonal antibody could be of clinical interest.

    The prognosis for diffuse large B-cell lymphoma (DLBCL) patients with early relapse or refractory disease is dismal. To determine if clinical outcome correlated to diverse serum metabolomic profiles, we used (1)H nuclear magnetic resonance (NMR) spectroscopy and compared two groups of DLBCL patients treated with immunochemotherapy: i) refractory/early relapse (REF/REL; n=27) and ii) long-term progression-free (CURED; n = 60). A supervised multivariate analysis showed a separation between the groups. Among discriminating metabolites higher in the REF/REL group were the amino acids lysine and arginine, the degradation product cadaverine and a compound in oxidative stress (2-hydroxybutyrate). In contrast, the amino acids aspartate, valine and ornithine, and a metabolite in the glutathione cycle, pyroglutamate, were higher in CURED patients. Together, our data indicate that NMR-based serum metabolomics can identify a signature for DLBCL patients with high-risk of failing immunochemotherapy, prompting for larger validating studies which could lead to more individualized treatment of this disease.

    Purpose: Cutaneous T-cell lymphoma (CTCL) is a radiosensitive tumor. Presently, treatment with radiation is given in multiple fractions. The current literature lacks data that support single-fraction treatment for CTCL. This retrospective review assesses the clinical response in patients treated with a single fraction of radiation. Methods and Materials: This study reviewed the records of 58 patients with CTCL, primarily mycosis fungoides, treated with a single fraction of palliative radiation therapy (RT) between October 1991 and January 2011. Patient and tumor characteristics were reviewed. Response rates were compared using Fisher's exact test and multiple logistic regressions. Survival rates were determined using the Kaplan-Meier method. Cost-effectiveness analysis was performed to assess the cost of a single vs a multifractionated treatment regimen. Results: Two hundred seventy individual lesions were treated, with the majority (97%) treated with ≥700 cGy; mean follow-up was 41.3 months (range, 3-180 months). Response rate by lesion was assessed, with a complete response (CR) in 255 (94.4%) lesions, a partial response in 10 (3.7%) lesions, a partial response converted to a CR after a second treatment in 4 (1.5%) lesions, and no response in 1 (0.4%) lesion. The CR in lower extremity lesions was lower than in other sites (P=.0016). Lesions treated with photons had lower CR than those treated with electrons (P=.017). Patients with lesions exhibiting large cell transformation and tumor morphology had lower CR (P=.04 and P=.035, respectively). Immunophenotype did not impact response rate (P=.23). Overall survival was significantly lower for patients with Sézary syndrome (P=.0003) and erythroderma (P<.0001). The cost of multifractionated radiation was >200% higher than that for single-fraction radiation. Conclusions: A single fraction of 700 cGy-800 cGy provides excellent palliation for CTCL lesions and is cost effective and convenient for the patient.

    Enteropathy-associated T-cell lymphoma (EATL) is a rare peripheral T-cell lymphoma classified into 2 types,with or without celiac disease,based on histology.Type 2 EATL is less commonly associated with celiac disease,in which cells are characterized by being monomorphic and small-to medium-sized.Cells are characterized by CD8 and CD56 expression and c-MYC oncogene locus gain.We present an atypical case of type 2 EATL in the jejunum,with human T-lymphotropic virus-1 that was CD4-CD8+ CD56-CD30-CD25-TIA-1+ and granzyme B+ on immunohistological staining.It also displayed translocation of chromosome 8p24 (c-MYC),as determined by fluorescent in situ hybridization.Mucosal spreading and intraepithelial invasion by lymphoma with villous atrophy were detected adjacent to the mucosal layer.The lymphoma may be derived from intraepithelial CD8+ T cells,similar to celiac disease.

    Twenty-six cases of adult T-cell leukemia/lymphoma (ATLL) were identified between 1983 and 1991 in Martinique (French West Indies). There were 14 men and 12 women, all of mixed racial descent and born in Martinique. Their ages ranged from 23 to 95 years. The main clinical and laboratory features at initial presentation were peripheral lymphadenopathy (22 cases), hepatomegaly (11 cases), splenomegaly (10 cases), cutaneous lesions (12 cases), hypercalcemia (16 cases), refractory infection by Strongyloides stercoralis (12 cases), and pre-existing autoimmune disorders (4 cases). All patients had absolute lymphocytosis with circulating pleomorphic abnormal lymphocytes. The prognosis was poor, with most patients (20 cases) surviving for less than 6 months. Although the overall clinicopathologic features of ATLL in this series are similar to those described in previous reports, we observed three additional points of interest: a high association with Strongyloides infection, an increased incidence of tropical spastic paresis/HTLV-1 associated myelopathy (TSP/HAM) among the relatives of the patients (5 cases), and the presence of prior collagen vascular diseases.

    Gene expression profiling (GEP) had divided the diffuse large B-cell lymphoma (DLBCL) into molecular subgroups: germinal center B-cell like (GCB), activated B-cell like (ABC), and unclassified (UC) subtype. However, this classification with prognostic significance was not applied into clinical practice since there were more than 1000 genes to detect and interpreting was difficult. To classify cancer samples validly, eight significant genes (MYBL1, LMO2, BCL6, MME, IRF4, NFKBIZ, PDE4B, and SLA) were selected in 414 patients treated with CHOP/R-CHOP chemotherapy from Gene Expression Omnibus (GEO) data sets. Cutoffs for each gene were obtained using receiver-operating characteristic curves (ROC) new model based on the support vector machine (SVM) estimated the probability of membership into one of two subgroups: GCB and Non-GCB (ABC and UC). Furtherly, multivariate analysis validated the model in another two cohorts including 855 cases in all. As a result, patients in the training and validated cohorts were stratified into two subgroups with 94.0%, 91.0%, and 94.4% concordance with GEP, respectively. Patients with Non-GCB subtype had significantly poorer outcomes than that with GCB subtype, which agreed with the prognostic power of GEP classification. Moreover, the similar prognosis received in the low (0-2) and high (3-5) IPI scores group demonstrated that the new model was independent of IPI as well as GEP method. In conclusion, our new model could stratify DLBCL patients with CHOP/R-CHOP regimen matching GEP subtypes effectively. PMID:26869285

    Rituximab is a monoclonal antibody routinely used in the treatment of B-cell non-Hodgkin lymphomas. It mediates antibody-dependent cellular cytotoxicity of B lymphocytes by bridging them with Fcγ receptors (FcγR) on effector cells. Several polymorphisms in the FcγR genes have been identified to influence rituximab binding to FcγR, thus altering its antitumor effect in indolent lymphomas. In the present study, the impact of FcγRIIa and FcγRIIIa polymorphisms on the survival and response to immunochemotherapy consisting of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone was evaluated in diffuse large B-cell lymphoma (DLBCL) patients. A total of 29 Slovenian DLBCL patients were studied. Genotyping was conducted for FcγRIIa-27, FcγRIIa-131, FcγRIIIa-48 and FcγRIIIa-158 polymorphisms. The median follow-up time was 29.7 months (range, 9.7–45.4 months). No significant impact of the genotypes was observed on the treatment response, progression-free or overall survival of DLBCL patients. There was a non-significant trend of an improved response to chemotherapy without additional irradiation in patients homozygous for Val at FCγIIIa-158 compared to Phe carriers. The findings of the present study indicate that FcγR polymorphisms have no influence on the survival of DLBCL patients.

    The primary vaginal T-cell non-Hodgkin lymphoma is a rare form of lymphoma. Most of the previously published cases were about B-cell non-Hodgkin lymphomas. We present the case of a vaginal mass in an 82-year-old patient presenting vaginal bleeding. The results of the immunohistological studies of the mass revealed the presence of a cytotoxic T-cell non-Hodgkin lymphoma, which is the least common subtype.

    We investigated the prognostic value of total metabolic tumour volume (TMTV) in diffuse large B-cell lymphoma (DLBCL). TMTV was measured in 114 patients with newly diagnosed DLBCL who underwent {sup 18}F-FDG PET/CT at baseline before immunochemotherapy. TMTV was computed by summing the volumes of all lymphomatous lesions after applying the local SUVmax threshold of 41 % using semiautomatic software. Prognostic value was assessed by Kaplan-Meier estimates of progression-free survival (PFS) and overall survival (OS). Median follow-up was 39 months. Average pretherapy TMTV was 509 ± 568 cm{sup 3}. The 3-year estimates of PFS were 77 % in the low metabolic burden group (TMTV ≤550 cm{sup 3}) and 60 % in the high metabolic burden group (TMTV >550 cm{sup 3}, p = 0.04), and prediction of OS was even better (87 % vs. 60 %, p = 0.0003). Cox regression showed independence of TMTV for OS prediction (p = 0.002) compared with other pretherapy indices of tumour burden, such as tumour bulk and the International Prognostic Index. Pretherapy TMTV is an independent predictor of outcome in patients with DLBCL. (orig.)

    Follicular lymphoma in situ (FLIS) and mantle cell lymphoma in situ (MCLIS) are histopathologic findings of undetermined clinical significance. We studied a series of 341 consecutive lymph node resection specimens from patients diagnosed with colorectal (201 cases) and breast (140 cases) adenocarcinoma between 1998 and 2000. Incidental and isolated FLIS was identified in 11/341 patients (3.23%), whereas incidental and isolated MCLIS was found in 2/341 patients (0.59%). None of these cases developed overt lymphoma. A second series of 17 cases of FLIS (16 cases) and MCLIS (1 case) from consultation files was analyzed. Five cases with incidental and isolated FLIS were identified. None of these cases developed overt lymphoma. Overall, none of the 16 cases with incidental and isolated FLIS in both series developed overt FL after a median follow-up of 54 months (range, 7 to 187 mo). However, 12 of these cases with a clinical suspicion of lymphoproliferative disorder showed the association (in different lymph nodes) or combination (in the same sample) of FLIS or MCLIS with other lymphoid neoplasms (FL, splenic marginal zone lymphoma, nodal marginal zone lymphoma, Hodgkin lymphoma, diffuse large B-cell lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma, multiple myeloma). In conclusion, the clinical relevance of FLIS and MCLIS seems to strictly depend on the clinical context. Incidental FLIS or MCLIS seem to have a very low risk for transformation, which recommends careful clinical examination after histopathologic diagnosis and conservative management with follow-up for a limited period of time.

  8. Primary nodal peripheral T-cell lymphomas: diagnosis and therapeutic considerations

    2015-08-01

    Full Text Available Nodal peripheral T-cell lymphomas are a rare group of neoplasms derived from post-thymic and activated T lymphocytes. A review of scientific articles listed in PubMed, Lilacs, and the Cochrane Library databases was performed using the term "peripheral T-cell lymphomas". According to the World Health Organization classification of hematopoietic tissue tumors, this group of neoplasms consists of peripheral T-cell lymphoma not otherwise specified (PTCL-NOS, angioimmunoblastic T-cell lymphoma (AITL, anaplastic large cell lymphoma-anaplastic lymphoma kinase positive (ALCL-ALK+, and a provisional entity called anaplastic large cell lymphoma-anaplastic lymphoma kinase negative (ALCL-ALK-. Because the treatment and prognoses of these neoplasms involve different principles, it is essential to distinguish each one by its clinical, immunophenotypic, genetic, and molecular features. Except for anaplastic large cell lymphoma-anaplastic lymphoma kinase positive, which has no adverse international prognostic index, the prognosis of nodal peripheral T-cell lymphomas is worse than that of aggressive B-cell lymphomas. Chemotherapy based on anthracyclines provides poor outcomes because these neoplasms frequently have multidrug-resistant phenotypes. Based on this, the current tendency is to use intensified cyclophosphamide, doxorubicin, vincristine, prednisolone (CHOP regimens with the addition of new drugs, and autologous hematopoietic stem cell transplantation. This paper describes the clinical features and diagnostic methods, and proposes a therapeutic algorithm for nodal peripheral T-cell lymphoma patients.

    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 with 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 indolent group

    MYC alterations influence the survival of patients with diffuse large B-cell lymphoma. Most studies have focused on MYC translocations but there is little information regarding the impact of numerical alterations and protein expression. We analyzed the genetic alterations and protein expression of MYC, BCL2, BCL6, and MALT1 in 219 cases of diffuse large B-cell lymphoma. MYC rearrangement occurred as the sole abnormality (MYC single-hit) in 3% of cases, MYC and concurrent BCL2 and/or BCL6 rearrangements (MYC double/triple-hit) in 4%, MYC amplifications in 2% and MYC gains in 19%. MYC single-hit, MYC double/triple-hit and MYC amplifications, but not MYC gains or other gene rearrangements, were associated with unfavorable progression-free survival and overall survival. MYC protein expression, evaluated using computerized image analysis, captured the unfavorable prognosis of MYC translocations/amplifications and identified an additional subset of patients without gene alterations but with similar poor prognosis. Patients with tumors expressing both MYC/BCL2 had the worst prognosis, whereas those with double-negative tumors had the best outcome. High MYC expression was associated with shorter overall survival irrespectively of the International Prognostic Index and BCL2 expression. In conclusion, MYC protein expression identifies a subset of diffuse large B-cell lymphoma with very poor prognosis independently of gene alterations and other prognostic parameters. PMID:23716551

    Central nervous system (CNS) relapse continues to be a frequent and usually fatal complication in patients with diffuse large B cell lymphoma (DLBCL). Multiple factors identify the possibility of relapse and justify neurological prophylaxis; however, most of these have not been confirmed. Thus, the use of prophylaxis has not been defined. From 1988 to 2008, 3,258 patients with DLBCL with higher clinical risks and multiple extranodal involvement that have been treated with standard anthracycline-based chemotherapy: CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) or CHOP-R (CHOP plus rituximab) and that achieve complete response were retrospectively analyzed to assess the efficacy of CNS prophylaxis. One thousand five patients received different schedules for CNS prophylaxis, and 2,253 patients did not receive CNS prophylaxis. CNS relapse was similar in patients who receive prophylaxis (6 %) compared to patients who did not receive prophylaxis (5.9 %). Overall survival of patients who either receive or did not receive prophylaxis was not statistically significant: 49 % versus 53 % (p = 0.802). Thus, it seems that CNS prophylaxis did not improve outcome in this special setting of patients, and no prognostic factors to predict the presence of CNS relapse were identified. It is evident that multicentric studies are necessary to define the role of prophylaxis in order to prevent CNS relapse and that the therapeutic procedure will be carefully revised. PMID:23456620

    Purpose: To analyze, through chart review, the efficacy of salvage radiation therapy (sRT) for relapsed or progressive Hodgkin lymphoma (HL) patients who failed autologous stem cell transplant (ASCT). Patients and Methods: Among 347 patients with recurrent/refractory HL who received ASCT from 1986-2006, 163 had post-ASCT progression or relapse. Of these, 56 received sRT and form the basis of this report. Median age at sRT was 30 years (range, 17-59 years). Disease was confined to lymph nodes in 27 patients, whereas 24 had both nodal and extranodal disease. Salvage radiation therapy alone was given in 34 patients (61%), and sRT plus chemotherapy was given in 22 (39%). Median interval from ASCT to sRT was 0.8 years (range, 0.1-5.6 years). The median dose was 35 Gy (range, 8-40.3 Gy). The sRT technique was extended-field in 14 patients (25%) and involved-field in 42 (75%). Results: The median follow-up from sRT was 31.3 months (range, 0.2-205.5 months). Overall response rate was 84% (complete response: 36%; partial response: 48%). The median overall survival was 40.8 months (95% confidence interval, 34.2-56.3 months). The 5-year overall survival was 29% (95% confidence interval, 14%-44%). The 2-year progression-free survival (PFS) was 16%; the 2-year local PFS was 65%, whereas the 2-year systemic PFS was 17%. The 1-year PFS was higher in patients in whom all diseased sites were irradiated (49%) compared with those in whom only the symptomatic site was treated (22%, P=.07). Among 20 alive patients, 5 were disease free (at 6.4, 6.8, 7.4, 7.9, and 17.1 years). Conclusion: For patients with HL who fail ASCT, a selective use of RT provides a durable local control rate of 65% at 2 years and should be considered as part of the standard management plan for the palliation of incurable HL. Occasionally irradiation of truly localized disease can lead to long-term survival.

    Full Text Available The establishment of a hamster lymphoma cell line was attempted. Simple mincing and trypsinization of lymphoma tissue resulted in a high degree of cell degeneration. The ascitic tumor cells produced by intraperitoneal transplantation of lymphoma tissue gave a better result. These ascitic cells grew and were cultured successively in medium consisting of RPMI 1640 and 20% fetal calf serum. Cells were round and grew in suspension. Accelerated cell growth was observed one month after starting the culture. In the stained preparations, cells were lymphoblastic. Cells were transplantable into new-born hamsters and produced tumors, but not in young adult hamsters.

    Full Text Available Posttransplant lymphoproliferative disorders (PTLDs comprise a wide spectrum of hematologic malignancies that are found increasingly in orthotopic liver transplant (OLT patients given the rising frequency of these surgeries and their long-term success. PTLDs are highly correlated with both the Epstein-Barr virus (EBV infection and the degree of immunosuppression involved. Herein is reported a case of a 53-year-old male with successfully treated hepatitis C virus genotype 4 and hepatocellular carcinoma who underwent OLT and developed symptoms of weakness and poor appetite 4 years later while on tacrolimus 3 mg b.i.d. with historically very low plasma levels. He was found to be anemic and colonoscopy revealed a 4.5 cm cecal diffuse large B-cell lymphoma (DLBCL. Further workup revealed mesenteric lymph node enlargement consistent and nodal DLBCL dissemination. He was treated with cyclophosphamide-hydroxyldaunorubicin-oncovin-prednisone-rituximab (CHOP-R chemotherapy and his tacrolimus dose was lowered. Additionally, he manifested PTLD-associated cryoglobulinemia leading to acute kidney injury. After a prolonged hospitalization he was discharged with close followup.

    Background: Extracellular circulating DNA (cfDNA) can be found in small amounts in plasma of healthy individuals. Increased levels of cfDNA have been reported in patients with cancer of breast, cervix, colon, liver and it was shown that cfDNA can originate from both tumour and non-tumour cells. Objectives: Levels of cfDNA of a large series of children with lymphoma were evaluated and analyzed in relation with clinical characteristics. Methods: plasma cfDNA levels obtained at diagnosis in 201 paediatric lymphoma patients [43 Hodgkin lymphomas (HL), 45 anaplastic large cell lymphomas (ALCL), 88 Burkitt lymphomas (BL), 17 lymphoblastic (LBL), 8 diffuse large B cell lymphoma (DLBCL)] and 15 healthy individuals were determined using a quantitative PCR assay for POLR2 gene and, in addition, for NPM-ALK fusion gene in ALCL patients. Wilcoxon rank sum test was used to compare plasma levels among different patient subgroups and controls and to analyze relationship between levels of cfDNA and clinical characteristics. Results: Levels of cfDNA in lymphoma patients were significantly higher compared with controls (p<0.0001). CfDNA was associated with median age (p=0.01) in HL, and with stage in ALCL (p=0.01). In HL patients high cfDNA levels were correlated with poor prognosis (p=0.03). In ALCL we found that most of the cfDNA (77%) was non-tumor DNA. Conclusion: level of plasma cfDNA might constitute an important non-invasive tool at diagnosis in lymphoma patients' management; in particular in patients with HL, cfDNA seems to be a promising prognostic biomarker.

    The aim of the study was to evaluate the efficacy of a regimen consisting of rituximab and a platinum-containing chemotherapy with either Ifosfamide, Carboplatin and Etoposide (ICE) or Cisplatin, high-dose Ara-C and Dexamethasone (DHAP) in patients with relapsed or primary refractory diffuse large B-cell lymphoma. Ten patients with relapsed or primary refractory diffuse large B-cell lymphoma were treated from June 2000 until May 2001 with a platinum-containing chemotherapy regimen according to the ICE- or DHAP-protocol in combination with rituximab at the University of Muenster. Two cycles of ICE or DHAP and rituximab were given. In case of at least a minor response after 2 cycles, 2 additional cycles of the same combination were applied. Response rate, remission duration and duration of survival were evaluated. All 10 patients could be analysed with respect to these endpoints. No treatment related mortality was observed. The response rate (CR/PR) was 60% (10/50%). Twenty percent of the patients had progressive disease. The median duration of remission and survival was 3 and 3.5 months, respectively (range: 1-6 and 1-7 months, respectively), the survival rate was 10%. Eight of 10 patients died because of their underlying disease with short remission duration, 1 patient died of complications of allogeneic transplantation in CR. In conclusion, the combination of platinum-containing chemotherapy (ICE or DHAP) with rituximab demonstrates significant activity in intensively pretreated patients with relapsed or primary refractory diffuse large B-cell lymphoma. Considering the short duration of remission and survival, respectively, other experimental therapeutic approaches (e.g. allogeneic stem cell transplantation, radioimmunotherapy) should be pursued following this treatment in order to induce long-term remission.

    Cutaneous T-cell lymphomas (CTCL) are a heterogeneous group of non-Hodgkin lymphomas that are considered incurable. The role of allogeneic hematopoietic stem cell transplantation (HSCT) in the treatment of CTCL is not well defined but may provide potent graft-vs-lymphoma (GVL) activity independent of the conditioning therapy. We present outcomes of 12 extensively-pretreated patients with CTCL who underwent allogeneic HSCT using, most commonly, a reduced intensity conditioning (RIC) regimen. M...

  11. Radioimmunotherapy for first-line and relapse treatment of aggressive B-cell non-Hodgkin lymphoma: an analysis of 215 patients registered in the international RIT-Network

    International Nuclear Information System (INIS)

    Very few reliable clinical data about the use of radioimmunotherapy in aggressive B-cell lymphoma exist. Patients with aggressive B-cell lymphoma registered in the international RIT-Network were analysed with regard to prior treatment, response and side effects. The RIT-Network is a web-based registry that collects observational data from radioimmunotherapy-treated patients with malignant lymphoma across 13 countries. This analysis included 215 with aggressive B-cell lymphoma out of 232 patients registered in the RIT-Network. Histological subtypes were as follows: 190 diffuse large B-cell, 15 primary mediastinal, 9 anaplastic large cell, and 1 intravascular lymphoma. The median age of the patients was 62 years (range 17 - 88), with 27 % above the age of 70 years. Radioimmunotherapy was mainly used as consolidation after first-line or second-line chemotherapy (56.1 %), as part of third-line to eighth-line therapy for relapse (16.4 %), and in refractory disease (12.2 %). Grade IV neutropenia and thrombopenia and grade III anaemia were observed. The median time to recovery of blood count was 81 days (range 0 - 600 days). The overall response rate was 63.3 %. The complete response rate was 76.4 % in patients treated as part of first-line therapy, and 44.3 % in patients with relapse. Mean overall survival in first-line therapy patients was 32.7 months and 14.0 months in patients with relapse or refractory disease, respectively. Most patients with aggressive B-cell lymphoma in the RIT-Network received radioimmunotherapy as consolidation after first-line therapy with excellent complete remission and overall survival rates compared to published data. In relapsed aggressive B-cell lymphoma, radioimmunotherapy is a safe and feasible treatment leading to satisfactory response rates with acceptable toxicity. (orig.)

    Full Text Available A 65-year-old gentleman presented with left groin swelling over the course of two months. Physical exam revealed nontender left inguinal adenopathy, and computed tomography scans detected multiple lymph nodes in the mesenteric, aortocaval, and right common iliac regions. An excisional lymph node biopsy was performed. Pathologic evaluation demonstrated follicular center site which stained positive for PAX5, CD20, CD10, Bcl-2, Bcl-6, and mantle zone cells. These findings demonstrated CCND1 and CD5 positivity, suggesting composite lymphoma comprising follicular lymphoma (FL with in situ mantle cell lymphoma (MCLIS. FL is known as indolent non-Hodgkin lymphoma; however, the clinical significance of a coexisting MCLIS continues to be elusive, and optimal management of these patients remains largely unknown. This case illustrates the diagnostic and therapeutic challenges of composite lymphomas. This paper also discusses advances in molecular pathogenesis and lymphoma genomics which offer novel insights into these rare diseases.

    Full Text Available Peripheral T-cell lymphomas are a group of rare neoplasms originating from clonal proliferation of mature post-thymic lymphocytes with different entities having specific biological characteristics and clinical features. As natural killer cells are closely related to T-cells, natural killer-cell lymphomas are also part of the group. The current World Health Organization classification recognizes four categories of T/natural killer-cell lymphomas with respect to their presentation: disseminated (leukemic, nodal, extranodal and cutaneous. Geographic variations in the distribution of these diseases are well documented: nodal subtypes are more frequent in Europe and North America, while extranodal forms, including natural killer-cell lymphomas, occur almost exclusively in Asia and South America. On the whole, T-cell lymphomas are more common in Asia than in western countries, usually affect adults, with a higher tendency in men, and, excluding a few subtypes, usually have an aggressive course and poor prognosis. Apart from anaplastic lymphoma kinase-positive anaplastic large cell lymphoma, that have a good outcome, other nodal and extranodal forms have a 5-year overall survival of about 30%. According to the principal prognostic indexes, the majority of patients are allocated to the unfavorable subset. In the past, the rarity of these diseases prevented progress in the understanding of their biology and improvements in the efficaciousness of therapy. Recently, international projects devoted to these diseases created networks promoting investigations on T-cell lymphomas. These projects are the basis of forthcoming cooperative, large scale trials to detail biologic characteristics of each sub-entity and to possibly individuate targets for new therapies.

    Diffuse large B-cell lymphoma (DLBCL) is the most common form of aggressive non-Hodgkin lymphoma, accounting for 30-40% of newly diagnosed cases. Obesity is a well-defined risk factor for DLBCL. However, the impact of body mass index (BMI) on DLBCL prognosis is controversial. Recent studies suggest that skeletal muscle wasting (sarcopenia) or loss of fat mass can be detected by computed tomography (CT) images and is useful for predicting the clinical outcome in several types of cancer including DLBCL. Several hypotheses have been proposed to explain the differences in DLBCL outcome according to BMI or weight that include tolerance to treatment, inflammatory background and chemotherapy or rituximab metabolism. In this review, we summarize the available literature, addressing the impact and physiopathological relevance of simple anthropometric tools including BMI and tissue distribution measurements. We also discuss their relationship with other nutritional parameters and their potential role in the management of patients with DLBCL. PMID:25363401

    Adult T-cell leukemia/lymphoma (ATLL) is usually preceded by infection with human T-cell lymphotropic virus I (HTLV-I). Patients with ATLL frequently get opportunistic infections of the lungs, intestines, and central nervous system. Pneumocystis pneumonia is commonly known as an AIDS defining illness. Grocott's methenamine silver stain of bronchoalveolar lavage (BAL) samples obtained via bronchoscopy remain the gold standard for diagnosis. Pulmonary cryptococcosis is seen in patients with T-cell deficiencies and a diagnosis is made by culture of sputum, BAL, or occasionally of pleural fluid. We present the second case of coinfection with these two organisms in a patient with ATLL who was successfully treated with trimethoprim-sulfamethoxazole, corticosteroids, and fluconazole. We illustrate the need for high clinical vigilance for seeking out an additional diagnosis, especially in immunocompromised patients if they are not improving despite receiving appropriate treatment.

    We analyzed the efficiency of the quantitative real-time PCR assay for cytomegalovirus (CMV) reactivation in adult T-cell leukemia-lymphoma (ATL) patients and compared the results with those obtained with qualitative nested PCR and antigenemia assays. The viral load obtained by the real-time PCR assay closely paralleled the number of antigen-positive cells obtained with the antigenemia assay. Real-time PCR revealed that a large number of DNA copies could be present even in samples assessed as...

    Introduction: T cells with the CD8 CD28– phenotype are CD8 lymphocytes with regulatory function. Their increased numbers were observed in infections, autoimmune and neoplastic diseases, and in elderly healthy individuals. CD8 CD28– lymphocyte levels in patients with cutaneous T-cell lymphoma (CTCL) has not yet been described. The aim of the study was to determine their levels in these patients’ peripheral blood and cutaneous infiltrates and their relation to the clinical stage of disease.Mat...

  3. Primary brain lymphoma in a patient after renal transplantation

    International Nuclear Information System (INIS)

    The incidence of primary central nervous system lymphoma (PCNSL) has increased during the past 40 years. This has been associated with immunodeficiency, mainly in patients infected with the human immunodeficiency virus (HIV) and in transplant patients. Tumor genesis is related with the Epstein-Barr virus (EBV). The most frequent PCNSL immuno phenotype is B-cell lymphoma. Clinical manifestations depend on tumor localization, and are usually behavior dysfunctions and intracranial hypertension syndrome. Differential diagnosis must take into consideration infectious processes, stroke, primary brain tumors, and metastases. The diagnosis of PCNSL requires brain MRI and brain biopsy. It is important to assess HIV infection when diagnosing PCNSL. This review reports a case of primary brain lymphoma in a patient who underwent renal transplantation due to polycystic kidney disease 8 years before.

  4. Follow-up of relapsed B-cell lymphoma patients treated with iodine-131-labeled anti-CD20 antibody and autologous stem-cell rescue

    International Nuclear Information System (INIS)

    Radioimmunotherapy (RIT) is a promising treatment approach for B-cell lymphomas. This is our first opportunity to report long-term follow-up data and late toxicities in 29 patients treated with myeloablative doses of iodine-131-anti-CD20 antibody (anti-B1) and autologous stem-cell rescue. PATIENTS AND METHODS: Trace-labeled biodistribution studies first determined the ability to deliver higher absorbed radiation doses to tumor sites than to lung, liver, or kidney at varying amounts of anti-B1 protein (0.35, 1.7, or 7 mg/kg). Twenty- nine patients received therapeutic infusions of single-agent (131)I- anti-B1, given at the protein dose found optimal in the biodistribution study, labeled with amounts of (131)I (280 to 785 mCi[10.4 to 29.0 GBq]) calculated to deliver specific absorbed radiation doses to the normal organs, followed by autologous stem-cell support. RESULTS: Major responses occurred in 25 patients (86%), with 23 complete responses (CRs; 79%). The nonhematopoietic do se-limiting toxicity was reversible cardiopulmonary insufficiency, which occurred in two patients at RIT doses that delivered > or = 27 Gy to the lungs. With a median follow-up time of 42 months, the estimated overall and progression-free survival rates are 68% and 42%, respectively. Currently, 14 of 29 patients remain in unmaintained remissions that range from 27+ to 87+ months after RIT. Late toxicities have been uncommon except for elevated thyroid-stimulating hormone (TSH) levels found in approximately 60% of the subjects. Two patients developed second malignancies, but none have developed myelodysplasia (MDS). CONCLUSION: Myeloablative (131)I-anti- B1 RIT is relatively well tolerated when given with autologous stem- cell support and often results in prolonged remission durations with few late toxicities

    Studies of associated cancer in patients with mycosis fungoides (MF) have focused primarily on secondary cancers in North American and European populations. This study investigated the association between MF and malignancies, anxiety and depression in the Israeli population. Data on Israeli patients with MF and age- and gender-matched controls were collected from a database of population- based cohort (683 patients; 1,700 controls) and an institution- based cohort (343 patients; 846 controls) and analysed by univariate and multivariate methods. MF was significantly associated with Hodgkin's lymphoma in both cohorts (multivariate odds ratio (OR) 7.83, univariate OR ∞, respectively); acute leukaemia (multivariate OR 10.1, first cohort) and lung cancer (multivariate OR 10.15, second cohort). MF was significantly associated with anxiety and depression (multivariate OR 1.59, OR 1.51, respectively in first cohort). The current study provides support to the associations between MF and other cancers: Hodgkin's lymphoma, acute leukaemia and lung cancer. The study also emphasizes the association between MF and anxiety and depression. PMID:23303582

    Full Text Available Primary non-Hodgkin’s lymphoma (NHL of the breast constitutes 0.04%-0.53% of all malignancies and 2.2% of extra nodal lymphomas. In total, 7%-8% of all B-cell lymphomas are the mucosa-associated lymphoid tissue (MALT type, of which up to 50% of primary gastric MALT lymphoma. Herein we present a patient with breast MALT lymphoma that transformed to diffuse large B-cell lymphoma (DLBCL. A 69-year-old female presented with a mass on her left breast. Physical examination showed a 3 × 3-cm mass located 1 cm from the areola on the upper lateral quadrant of the breast at the 1 o’clock position, which was fixed and firm. Excisional biopsy was performed and pathologic examination of the specimen showed MALT lymphoma transformation to DLBCL. The patient was staged as II-EA. The rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP protocol was scheduled as treatment. Following 6 courses of R-CHOP, 2 additional courses of rituximab were administered. Positron emission tomography (PET-CT was done at the end of the treatment. PET showed that the patient was in complete remission. At the time this report was written, the patient was being followed-up at the outpatient clinic on a regular basis. Lymphoma of the breast is a rarity among malignant tumors of the breast. The most common type of lymphoma is DLBCL. Breast MALT lymphoma is extremely rare. Primary MALT lymphoma of the breast can transform from low grade to high grade and recurrence is possible; therefore, such patients should be monitored carefully for transformation.

    BACKGROUND: The added diagnostic and prognostic value of routine bone marrow biopsy (BMB) in patients with diffuse large B-cell lymphoma (DLBCL) undergoing PET/CT staging is controversial. PATIENTS AND METHODS: Patients with newly-diagnosed DLBCL who underwent both staging PET/CT and BMB were...... marrow (BM) lesions on PET/CT and 87 (16%) had positive BMB. 52 of 146 patients (36%) with positive PET/CT had a positive BMB (39 DLBCL, 13 indolent non-Hodgkin lymphoma [iNHL]), while 35 of 384 patients (9%) with negative PET/CT had positive BMB (12 DLBCL, 23 iNHL). BMB upstaged 12/209 (6%) of stage I....../II patients to stage IV, although this was the case for only 3 (1%) patients with DLBCL in the BMB. PET/CT identified bone marrow involvement by BMB with sensitivity 60%, specificity 79%, positive predictive value 36%, and negative predictive value 91%.

    We retrospectively evaluated the role of rituximab (R) in maintenance treatment after autologous stem cell transplantation performed in patients with relapsed follicular lymphoma. We compared the outcome of 67 follicular lymphoma (FL) patients according to the use of rituximab maintenance (RM) or not. All patients received rituximab plus chemotherapy before autologous stem-cell transplantation (ASCT). Patients received median of two lines of prior therapy. The RM schedule was one injection of rituximab every 3 months for 2 years. Median follow-up is 4.6 years. The 3-year progression-free survival (PFS) after ASCT was 86 % with RM vs. 46 % without (p = 0.0045). Median is not reached in the RM arm vs. 31 months in non-RM arm. The 3-year OS was 96 % with RM vs. 78 % without (p = 0.059). The present monocentric study shows that 2 years of RM after ASCT significantly increases response duration for non-naive rituximab relapsed FL patients compared with observation. PMID:27297970

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

    Brentuximab vedotin induces an overall response rate of 75% in patients with relapsed/refractory Hodgkin lymphoma, but its impact on future allogeneic transplantation (allo-HCT) is not known. We retrospectively examined the records of 18 patients with relapsed/refractory Hodgkin lymphoma who were treated on brentuximab vedotin clinical trials to evaluate the efficacy and safety of subsequent reduced-intensity allo-HCT. Seventeen patients had previous autologous transplant; 6 were in complete remission, and 8 were in partial remission before allo-HCT with 12 grafts from unrelated or mismatched donors. The 1-year overall survival was 100%, progression-free survival was 92.3%, and nonrelapse mortality was 0% (median follow-up, 14 months). The incidence of acute GVHD was 27.8% and chronic GVHD was 56.3%. Brentuximab vedotin before reduced-intensity allo-HCT does not appear to adversely affect engraftment, GVHD, or survival and may provide sufficient disease control to enable reduced-intensity allo-HCT.

  13. Increased risk of gastric adenocarcinoma after treatment of primary gastric diffuse large B-cell lymphoma

    International Nuclear Information System (INIS)

    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

    Full Text Available A sixty-three-year-old man who had had Hodgkin lymphoma twenty years earlier and laryngeal mucosa associated lymphatic tissue lymphoma (MALToma two years earlier and had been treated with radiotherapy and chemotherapy was admitted to our ward with cough and hemoptysis. Physical examination revealed decreased breath sounds on the left hemitorax incomparison to the right. On chest x-ray and thoracic CT, at the left hilar region, there was a 6x5x5cm-sized, malignant-appearing mass with invasion to the hilar vascular structures. An endobronchial lesion was seen on fiberoptic bronchoscopy. The histology of the biopsy specimen was reported as squamous cell carcinoma. The patient was treated with chemotherapy and radiotherapy with the diagnosis of stage 3B lung carcinoma and is still on treatment. We want to present this case with literature reviews, as lymphoma, MALToma and carcinoma in the same patient is extremely rare.

    Discovering prognostic factors that simultaneously describe tumor characteristics and improve risk stratification is a priority in cutaneous T-cell lymphoma (CTCL). More than a third of advanced stage CTCL patients in this cohort had detectable cell free plasma Epstein–Barr virus (EBV)-DNA (pEBVd) using quantitative real-time polymerase chain reaction. An increased level of pEBVd was highly concordant with EBV (ie, Epstein–Barr virus RNAs) in tumor tissue and was associated with inferior survival. Introduction Outcomes in advanced stage (AS) cutaneous T-cell lymphomas (CTCL) are poor but with great variability. Epstein–Barr virus (EBV) is associated with a subset of non-Hodgkin lymphomas. Frequency of plasma EBV-DNA (pEBVd) detection, concordance with EBV RNA (EBER) in tumor tissue, codetection of plasma cytomegalovirus DNA (pCMVd), and prognostic effect in AS CTCL are unknown. Patients and Methods Patients (n = 46; 2006–2013) with AS CTCL (≥IIB) were retrospectively studied. pEBVd and pCMVd were longitudinally measured using quantitative real-time polymerase chain reaction. EBER in situ hybridization (ISH) was performed on tumor samples. Survival from time of diagnosis (ToD) and time of progression to AS was assessed. Results Plasma EBV-DNA and pCMVd were detected in 37% (17 of 46) and 17% (8 of 46) of AS CTCL patients, respectively. pCMVd detection was significantly more frequent in pEBVd-positive (pEBVd+) than pEBVd− patients (35% vs. 7%; P = .038). Tumor tissue for EBER-ISH was available in 14 of 17 pEBVd+ and 22 of 29 pEBVd− patients; 12 of 14 (85.7%) pEBVd+ patients were EBER+ versus 0 of 22 pEBVd− patients. Frequency of large cell transformation (LCT) tended to be greater in pEBVd+ patients, but was not significant (10 of 14 pEBVd+ vs. 10 of 23 pEBVd−; P = .17). No notable differences in rates of increased levels of serum lactate dehydrogenase (LDH) were observed (17 of 17 pEBVd+ vs. 27 of 29 pEBVd−). pEBVd detection was associated with

    2008-10-01

    Mantle cell lymphoma (MCL) is a therapeutic challenge because of its lower cure rate when compared with other lymphomas such as diffuse large cell lymphoma. The current emphasis in the treatment of newly diagnosed MCL has been on intensifying chemotherapy, but there is no consensus on the need to consolidate with autologous stem cell transplantation. These approaches, however, have not resulted in a cure. Newer strategies include the use of models to aid in tailoring therapy. Likewise, autologous stem cell consolidation does not cure relapsed disease. Because of its known graft-versus-lymphoma effect, allogeneic stem cell transplantation offers a potentially curative option for relapsed MCL. New insights into resistance pathways and new drugs created to inhibit them offer great promise in the treatment of newly diagnosed and previously treated MCL. PMID:20425467

    Non-myeloablative conditioning hematopoietic cell transplantation (NMC-HCT) has improved the treatment of chronic lymphocytic leukemia (CLL) and follicular lymphoma (FL). In a cohort of 85 patients (45 with CLL and 40 with FL), we observed 5-yr overall survival (OS) and progression-free survival...... (PFS) of 53% and 38% in the CLL group and 81% and 76% in the FL group. In the both the CLL group and the FL group, a strong trend toward better OS and PFS was observed among patients in complete remission (CR) at HCT. Within the FL group, sixteen patients had at one or more time points in their disease...... history had transformed FL. In contrast to the poor survival found in patients with transformed FL in previous studies, the 5-yr OS was almost identical in patients with transformed and non-transformed FL, 83% and 78%, respectively. In conclusion, our study supports that NMC-HCT is a safe and efficacious...

    Full Text Available Xueyan Chen, Lorinda A Soma, Jonathan R FrommDepartment of Laboratory Medicine, University of Washington Medical Center, Seattle, WA, USAAbstract: Despite the relative success of chemotherapy for Hodgkin lymphoma (HL and systemic anaplastic large cell lymphoma (ALCL, novel therapeutic agents are needed for refractory or relapsed patients. Targeted immunotherapy has emerged as a novel treatment option for these patients. Although unconjugated anti-cluster of differentiation (CD30 antibodies showed minimal antitumor activity in early clinical trials, development of antibody–drug conjugates (ADCs appears promising. Brentuximab vedotin is an ADC composed of an anti-CD30 antibody linked to a potent microtubule-disrupting agent monomethyl auristatin E (MMAE. It has the ability to target CD30-positive tumor cells and, once bound to CD30, brentuximab vedotin is internalized and MMAE is released to induce cell cycle arrest and apoptosis. In two phase II trials, objective response was reported in 75% and 86% of patients with refractory or relapsed HL and systemic ALCL, respectively, with an acceptable toxicity profile. Based on these studies, the US Food and Drug Administration (FDA granted accelerated approval of brentuximab vedotin in August 2011 for the treatment of refractory and relapsed HL and ALCL. We review the key characteristics of brentuximab vedotin, clinical data supporting its therapeutic efficacy, and current ongoing trials to explore its utility in other CD30-positive malignancies.Keywords: classical Hodgkin lymphoma, systemic anaplastic large cell lymphoma, CD30, brentuximab vedotin, SGN-35

    Sixteen patients - 12 with cutaneous T cell lymphoma (CTCL), 1 with Sézary syndrome, 1 with actinic reticuloid, and 2 with parapsoriasis variegata - were treated with either a new, potent arotinoid alone or with combined etretinate (Tigason) and PUVA therapy (Re-PUVA). 92% of all patients showed a minor up to a distinct response of their skin lesions within 12.6 +/- 7.4 weeks. More than 50% of the skin lesions cleared in 67% of the patients. After discontinuation of the retinoid therapy, relapses occurred in all cases within 3-10 weeks. There was no difference between the therapeutic efficacy of arotinoid alone and the Re-PUVA regimen, but the latter was less toxic. PMID:3500880

    In large B-cell lymphoma (LBCL) MYC- and MYC/BCL2 double-hit (DH) translocations have been associated with inferior survival. We hypothesised that the negative prognostic impact of MYC translocation was determined by an immunoglobulin MYC translocation partner gene (IG-MYC), as opposed to a non......-immunoglobulin partner gene (nonIG-MYC). In a prospective, unselected cohort of 237 LBCL patients MYC and BCL2 translocations were identified by fluorescent in situ hybridisation (FISH) with split probes. MYC translocation partner gene was identified by IGH/MYC fusion probes and/or kappa/lambda split probes. Clinical...

    Diffuse large B cell lymphoma (DLBCL) is one of the most common types of malignancy worldwide. The lack of clear symptoms and early detection make it difficult to diagnose at an early stage, leading to poor prognosis of the patients. Long non‑coding RNAs (lncRNAs) have come into focus for their important regulatory roles in fundamental biological processes, particularly in cancer initiation, development and progression. The aim of the present study was to investigate the expression of lncRNA Hox transcript antisense intergenic RNA (HOTAIR) in a cohort of patients with DLBCL to assess its clinical value and biological function in DLBCL. The reverse transcription‑polymerase chain reaction was used to detect HOTAIR expression levels and cells were transfected with small interfering RNA to compare cell proliferation, cell cycle progression and apoptosis. Western blotting was also conducted to detect possible signaling pathways. It was first found that the expression levels of HOTAIR were upregulated in DLBCL tumor tissues and cell lines, compared with normal tissues and cells. In addition, HOTAIR was significantly correlated with tumor size, clinical stage, B symptoms and International Prognostic Index scores; and higher expression levels of HOTAIR were correlated with improved prognosis. Univariate and multivariate analyses verified that HOTAIR was a key independent predictive factor for DLBCL prognosis. Furthermore, it was revealed that the knockdown of the expression of HOTAIR led to growth inhibition, cell cycle arrest and apoptosis in vitro, possibly through the phosphoinositide 3‑kinase/AKT/nuclear factor‑κB pathway. These results suggested that HOTAIR may be regarded as a novel indicator of poor prognosis, and may serve as a potential target for gene therapy in the treatment of DLBCL. PMID:27122348

    We report a case that demonstrates the efficacy of radioimmunotherapy (RIT) with radioiodinated rituximab ({sup 131}I-rituximab) for relapsed diffuse large B-cell lymphoma (DLBCL). A 79-year-old male patient with DLBCL initially achieved a complete response (CR) after six cycles of RCHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) therapy. However, the lymphoma relapsed 20 months later. Although the patient had achieved a second and a third CR after two cycles of {sup 90}Y-ibritumomab tiuxetan, he experienced a third relapse approximately 3 years later. Between March and June 2011, the patient received three cycles of {sup 131}I-rituximab. Although he had achieved partial response after the second cycle, the disease progressed after the third cycle, and the total progression. Free survival was thus 5 months. The patient suffered only relatively mild toxicity (grade 1 thrombocytopenia) during treatment. RIT with {sup 131}I-rituximab is therefore potentially effective in patients with relapsed DLBCL, even after the failure of {sup 90}Y-ibritumomab tiuxetan therapy.

    Full Text Available Abstract Background Sjögren’s syndrome is a systemic autoimmune disease in which lymphatic cells destroy the salivary and lacrimal glands. Glomerulonephritis is thought to be a rare occurrence in primary Sjögren’s syndrome. Furthermore, concurrent glomerular involvement and lymphoma in patients with Sjögren’s syndrome has seldom been reported. Case presentation A 52-year-old woman with primary Sjögren’s syndrome developed membranous glomerulonephritis and Epstein-Barr virus-positive diffuse large B-cell lymphoma (DLBCL. She was diagnosed with Sjögren’s syndrome based on the dry eyes, dry mouth, positive anti-nuclear antibody test, anti-Ro (SS-A antibody, salivary gland biopsy, and salivary scintigraphy. Moreover, renal biopsy confirmed the diagnosis of membranous glomerulonephritis. Three months later, her small bowel was perforated with pneumoperitoneum, and the biopsy revealed Epstein-Barr virus-positive DLBCL. Conclusions We observed the first case of primary Sjögren’s syndrome associated with Epstein-Barr Virus-positive DLBCL and membranous glomerulonephritis. Because of the possibility of malignancy-associated membranous glomerulonephritis in patients with primary Sjögren’s syndrome, we should be careful and examine such patients for hidden malignancy.

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

    A phase 1 study with carfilzomib and vorinostat was conducted in 20 B-cell lymphoma patients. Vorinostat was given orally twice daily on days 1, 2, 3, 8, 9, 10, 15, 16, and 17 followed by carfilzomib (given as a 30-min infusion) on days 1, 2, 8, 9, 15, and 16. A treatment cycle was 28 days. Dose escalation initially followed a standard 3 + 3 design, but adapted a more conservative accrual rule following dose de-escalation. The maximum tolerated dose was 20 mg/m(2) carfilzomib and 100 mg vorinostat (twice daily). The dose-limiting toxicities were grade 3 pneumonitis, hyponatremia, and febrile neutropenia. One patient had a partial response and two patients had stable disease. Correlative studies showed a decrease in NF-κB activation and an increase in Bim levels in some patients, but these changes did not correlate with clinical response. PMID:26284612

    Rhodotorula is a ubiquitous yeast that can infect immunocompromised patients. Here, we present the case of a 45-year-old patient with AIDS who developed a Rhodotorula mucilaginosa fungemia. The patient had a past history of visceral leishmaniasis (VL) and was hospitalised to receive chemotherapy for a B-cell lymphoma of the sinonasal cavities. The patient had no fever and no signs of VL. A systematic research for Leishmania by blood and bone marrow cultures was made and he received liposomal amphtotericin B (3 mg/kg in a single dose) to prevent a VL relapse. Rhodotorula fungemia was accidentally detected after 17 days of blood culture using a specific medium for leishmaniasis diagnosis. This long culture incubation time was probably facilitated by amphotericin B treatment. Rhodotorula is an emerging pathogen that may escape detection due its slow growth in culture. PMID:23505931

  8. Treatment and prognosis of primary gastric B-cell lymphoma. Special Reference to therapeutic strategy of MALT lymphoma

    International Nuclear Information System (INIS)

    To evaluate the influence of therapeutic methods on the prognosis of primary gastric B-cell lymphoma, we analyzed the prognostic factors for 322 patients, comprised of 186 with low-grade mucosa-associated lymphoid tissue (MALT) lymphoma, 54 with diffuse large B-cell lymphoma (DLBL) plus MALT lymphoma, and 82 with DLBL without MALT lymphoma. Among them, the clinical course of 96 patients who were treated by Helicobacter pylori eradication was also evaluated. Patients who underwent stomach-conserving treatment (H. pylori eradication, chemotherapy or radiation; n=100) showed a better overall survival probability than those treated by surgery (n=222), but the progression-free probability did not differ between the two groups. After H. pylori eradication, complete remission was achieved in 55 patients, of whom histologic relapse was observed in 4 patients (7%). Second line treatment for 34 patients, who failed to respond to eradication therapy, including oral monochemotherapy with cyclophosphamide, radiation, CHOP (CHOP; cyclophosphamide, doxorubicin, vincristine, prednisolone) chemotherapy, and gastrectomy resulted in complete remission in 29 patients (85%). These results suggest stomach- conserving treatment to be an optimal therapeutic modality for primary gastric B-cell lymphoma. (author)

    The risk of developing non-Hodgkin lymphoma increases with age, yet elderly patients are under-represented in clinical trials. Here, we evaluate a combination regimen including ifosfamide, carboplatin and etoposide with or without rituximab (ICE ± R) in 32 fit elderly patients (median age 75.6 years) with relapsed or refractory diffuse large B-cell lymphoma. ICE ± R was generally administered in reduced doses and was well tolerated. The overall response rate (ORR) was 53.1% with a complete response (CR) rate of 40.6%. The median progression free survival (PFS) and overall survival (OS) were 3.9 and 17.0 months, respectively. Patients who responded to ICE ± R achieved median PFS of 47.2 months and OS of 78.9 months. Patients ineligible for autologous transplantation who responded to ICE ± R were treated with additional cycles, and achieved a median PFS of 18.9 months and OS of 21.7 months. Previous response to first-line therapy was the strongest predictor of response, PFS and OS to second-line treatment. PMID:26643787

    Peripheral T-cell lymphomas (PTCL) have suboptimal outcomes using conventional CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy. The anti-folate pralatrexate, the first drug approved for patients with relapsed/refractory PTCL, provided a rationale to incorporate it into the front-line setting. This phase 2 study evaluated a novel front-line combination whereby cyclophosphamide, etoposide, vincristine and prednisone (CEOP) alternated with pralatrexate (CEOP-P) in PTCL. Patients achieving a complete or partial remission (CR/PR) were eligible for consolidative stem cell transplantation (SCT) after 4 cycles. Thirty-three stage II-IV PTCL patients were treated: 21 PTCL-not otherwise specified (64%), 8 angioimmunoblastic T cell lymphoma (24%) and 4 anaplastic large cell lymphoma (12%). The majority (61%) had stage IV disease and 46% were International Prognostic Index high/intermediate or high risk. Grade 3-4 toxicities included anaemia (27%), thrombocytopenia (12%), febrile neutropenia (18%), mucositis (18%), sepsis (15%), increased creatinine (12%) and liver transaminases (12%). Seventeen patients (52%) achieved a CR. The 2-year progression-free survival and overall survial, were 39% (95% confidence interval 21-57) and 60% (95% confidence interval 39-76), respectively. Fifteen patients (45%) (12 CR) received SCT and all remained in CR at a median follow-up of 21·5 months. CEOP-P did not improve outcomes compared to historical data using CHOP. Defining optimal front line therapy in PTCL continues to be a challenge and an unmet need. PMID:26627450

    Full Text Available Epigenetic alterations of gene expression are important in the development of cancer. In this study, we identified genes which are epigenetically altered in major lymphoma types. We used DNA microarray technology to assess changes in gene expression after treatment of 11 lymphoma cell lines with epigenetic drugs. We identified 233 genes with upregulated expression in treated cell lines and with downregulated expression in B-cell lymphoma patient samples (n = 480 when compared to normal B cells (n = 5. The top 30 genes were further analyzed by methylation specific PCR (MSP in 18 lymphoma cell lines. Seven of the genes were methylated in more than 70% of the cell lines and were further subjected to quantitative MSP in 37 B-cell lymphoma patient samples (diffuse large B-cell lymphoma (activated B-cell like and germinal center B-cell like subtypes, follicular lymphoma and Burkitt`s lymphoma and normal B lymphocytes from 10 healthy donors. The promoters of DSP, FZD8, KCNH2, and PPP1R14A were methylated in 28%, 67%, 22%, and 78% of the 36 tumor samples, respectively, but not in control samples. Validation using a second series of healthy donor controls (n = 42; normal B cells, peripheral blood mononuclear cells, bone marrow, tonsils and follicular hyperplasia and fresh-frozen lymphoma biopsies (n = 25, confirmed the results. The DNA methylation biomarker panel consisting of DSP, FZD8, KCNH2, and PPP1R14A was positive in 89% (54/61 of all lymphomas. Receiver operating characteristic analysis to determine the discriminative power between lymphoma and healthy control samples showed a c-statistic of 0.96, indicating a possible role for the biomarker panel in monitoring of lymphoma patients.

    Full Text Available Non-Hodgkin lymphomas encompass a heterogeneous group of cancers, with 85–90% arising from B lymphocytes and the remainder deriving from T lymphocytes or NK lymphocytes. These tumors are molecularly and clinically heterogeneous, showing dramatically different responses and outcomes with standard therapies. Deregulated PI3K signaling is linked to oncogenesis and disease progression in hematologic malignancies and in a variety of solid tumors and apparently enhances resistance to antineoplastic therapy, resulting in a poor prognosis. Here, we have evaluated and compared the effects of the pan-PI3K inhibitor BKM120 and the dual PI3K/mTOR inhibitor BEZ235 on mantle, follicular, and T-cell lymphomas. Our results suggest that BKM120 and BEZ235 can effectively inhibit lymphoma cell proliferation by causing cell cycle arrest and can lead to cell death by inducing apoptosis and autophagy mediated by ROS accumulation. Despite great advances in lymphoma therapy after the introduction of monoclonal antibodies, many patients still die from disease progression. Therefore, novel treatment approaches are needed. BKM120 and BEZ235 alone and in combination are very effective against lymphoma cells in vitro. If further studies confirm their effectiveness in animal models, they may be promising candidates for development as new drugs.

    Full Text Available ABSTRACT:Background: Follicular lymphoma (FL is the most common subtype of indolent lymphoma. FL is still considered to be an incurable disease and palliation of symptoms is an acceptable approach to the expected pattern of repeated relapses due to developing resistance to chemotherapy agents. Apurinic/apyrimidinic endonuclease/redox factor-1 (APE1/Ref-1 is a multifunctional protein involved in DNA base excision repair (BER of oxidative DNA damage and in redox regulation of a number of transcription factors. It was observed that cytoplasmic APE1 induced COX-2 expression through NF-êB activation. It has been shown that chemopreventive agents potentiate the efficacy of chemotherapy through the regulation of multiple signaling pathways, including NF-êB, c-Myc, cyclooxygenase-2, apoptosis, and others, suggesting a multitargeted nature of chemopreventive agents. We hypothesized that curcumin, a polyphenolic antioxidant derived from the spice turmeric, and epigallocatechin gallate (EGCG from green tea would potentiate the effect of chemotherapy in B-cell lymphoma.Objective: We examined the role of human apurinic/apyrimidinic endonuclease 1 (APE1 in resistance and prognosis in patients with FL. Our major objective was to update the safety and efficacy results of the antitumor effect of combination of curcumin and EGCG therapy in relapsed or resistant indolent or transformed non-Hodgkin follicular lymphoma patients and their peripheral blood mononuclear cells (PBMCs compared with healthy donors’ controls.Methods: Thirty patients with FL with over-expression of constitutive active NF-êB in their PBMCs received regular CHOP and consumed capsules compatible with curcumin doses between 0.9 and 5.4 g daily for up to 9 months and 9.0 g/day green tea whole extract "1000 mg tablets of green tea whole extract containing 200 mg EGCG.

    Lymphomas arise from clonal expansions of B, T, or NK cells at different stages of differentiation. Because they occur in the immunocyte-rich lymphoid tissues, they are easily accessible to antibodies and cell-based immunotherapy. Expressing chimeric antigen receptors (CARs) on T cells is a means of combining the antigen-binding site of a monoclonal antibody with the activating machinery of a T cell, enabling antigen recognition independent of major histocompatibility complex restriction, while retaining the desirable antitumor properties of a T cell. Here, we discuss the basic design of CARs and their potential advantages and disadvantages over other immune therapies for lymphomas. We review current clinical trials in the field and consider strategies to improve the in vivo function and safety of immune cells expressing CARs. The ultimate driver of CAR development and implementation for lymphoma will be the demonstration of their ability to safely and cost-effectively cure these malignancies. PMID:26332003

  1. DNA double strand breaks in fibroblast cell lines from non-Hodgkin's lymphoma patients showing increased sensitivity to chronic gamma irradiation

    International Nuclear Information System (INIS)

    Cultured skin fibroblast cell lines from two non-Hodgkin's lymphoma patients (NHL) and a normal subject were studied for cell killing, chromosomal aberrations (breaks, translocations, dicentrics and rings) and DNA double strand breaks (dsbs) following chronic gamma irradiation. Compared to the cell line from the normal donor, the NHL patients' fibroblasts showed enhanced radiosensitivity for both cell survival and chromosomal aberrations. While spontaneous breaks were observed in both normal and patients' cells, spontaneous translocations and radiation-induced dicentrics and rings were found only in the latter. Radiation-induced DNA double-strand breaks (dsb) were determined by CHEF electrophoresis. After chronic irradiation with gamma rays the fraction of residual dsb was significantly increased from 1.4% in controls to 1.9% in the NHL cell lines. These data, thus suggest that the cellular and chromosomal sensitivity to chronic irradiation observed in NHL patients may be due to a deficiency in the repair of a small fraction of DNA double strand breaks.

    International Nuclear Information System (INIS)

    Five cases of primary mediastinal large-cell lymphoma with sclerosis diagnosed at the University Hospital Clementino Fraga Filho (Federal University of Rio de Janeiro) between 1986 and 1994 were identified. They were studied on clinical, morphological and immuno-histochemical grounds. Clinically, the disease was characterized by the young age of the patients, mediastinal involvement by bulky disease and compressive symptoms. None of the patients had evidence of extra-thoracic disease as presentation. On morphological grounds they had evidence of extra-thoracic disease at presentation. On morphological grounds they showed a mixture of immuno blasts and large follicular enter cell with sclerosis. Three of five cases proved to be of B-cell origin. Four of five patients were treated with chemotherapy. Cases 1 and with MACOP-B, and cases 3 and 4 with Pro-MACE-cytaBOM and consolidation radiation therapy. All the patients achieved a complete remission, and are alive, free of disease, with a follow-up of 1 to 8 years. (author). 28 refs., 8 figs., 2 tabs

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

    Adult T-cell leukemia/lymphoma (ATLL) is a T-cell neoplasm, associated with infection by the retrovirus human T-lymphotropic virus type 1 (HTLV-1). Central nervous system (CNS) involved by ATLL is often occurred in advanced disease, such as acute and lymphomatous variants. On the other hand, isolated CNS lymphoma is rare. We repot a 50-year-old woman who presented with multiple infiltrative brain lesions on the magnetic resonance (MR) imaging. Results of initial biopsy of brain tumor indicated CNS vasculitis. The patient received one course of high-dose methotrexate and MR imaging of brain revealed remission of infiltrative lesions. Two years later, new brain lesions were detected. Histopathologic examination of specimens via craniotomy revealed T-cell lymphoma. The patient responded poorly to subsequent chemotherapy, and salvage whole-brain irradiation was performed. Six months later, the patient had hepatosplenomegaly, hypercalcemia, and multiple lymphocytes with a cloverleaf appearance in circulation. Results of flow cytometry analysis of peripheral blood indicated ATLL and antibodies to human T-lymphotropic virus type 1 (HTLV-1) were detected. Clinicians should screen HTLV-1 infection when patients are diagnosed with peripheral T-cell lymphoma. Combined antiviral therapy and intensive chemotherapy may improve the outcomes of ATLL.

    BCL2 and MYC are oncogenes often deregulated in lymphomas. Concurrent IGH-BCL2 and MYC translocations result in a highly aggressive behavior of these tumors. Both primary breast lymphoma and lymphoma with concurrent BCL2-IGH and MYC translocations are rare and are primarily seen in adult patients. As a result of limited clinician experience and the condition's rarity, it poses a great challenge to pediatric pathologists and oncologists in terms of making an accurate diagnosis and choosing better treatment regimens. In this article, we report a case of an adolescent patient who presented with high-grade breast lymphoma with concurrent BCL2-IGH and MYC-IGL translocations, and we review the clinical, pathological, and genetic features; management strategies; and outcomes associated with this unusual neoplasm.

    This phase II study evaluated YM155, a novel small-molecule survivin suppressant, in combination with rituximab in patients with relapsed aggressive B-cell non-Hodgkin lymphoma (NHL) who failed or were not candidates for autologous stem cell transplant (ASCT). During 14-day cycles, 41 patients received YM155 (5mg/m(2)/d) by continuous intravenous (IV) infusion for 168 hours (day 1-7), and rituximab (375mg/m(2)) IV on days 1 and 8 during cycles 1-4 and repeated for 4 cycles every 10 cycles. Forty patients (97.6%) had prior rituximab and 15 patients (36.6%) prior ASCT. Most frequent grade 3-4 adverse events were neutropenia (19.5%) and thrombocytopenia (12.2%). In the per-protocol set (n = 34), objective response rate was 50% and median progression-free survival 17.9 months. Median overall survival was not reached at study termination (median follow-up, 23 months). YM155 in combination with rituximab was tolerable with encouraging antitumor activity and durable responses in relapsed aggressive B-cell NHL patients. PMID:26857688

    Primary marginal zone B-cell MALT-type lymphomas of the uterine corpus are exceedingly rare entities, with only 6 cases reported in the literature to date. We present the additional case of a 70-yr-old white woman who underwent a laparoscopic total hysterectomy with bilateral salpingo-oophorectomy for an asymptomatic ovarian cyst. At microscopic examination, endometrial samples showed a dense, nodular lymphocytic infiltrate, suggestive of a lymphoproliferative disorder. Morphology, immunohistochemistry, and molecular analysis supported the diagnosis of MALT-type lymphoma of the endometrium. Benign reactive conditions, such as endometritis and other small B-cell lymphomas were ruled out. Moreover, we investigated the pathogenesis of our case, focusing on Chlamydia trachomatis infection, chromosomal translocations affecting the NF-kB pathway, and discussing the role of autoimmunity in the development of MALT-type lymphomas.

    Full Text Available Primary colorectal lymphoma is a rare malignancy accounting for 3% of all gastrointestinal lymphomas and 0.1-0.5% of all colorectal malignancies. Among primary colorectal lymphomas, the most common histological subtype of colorectal lymphoma is diffuse large B-cell lymphoma. We report a case of an 84-year old Caucasian female who was admitted to the hospital because of a 2 days history of altered mental status. In the emergency department the patient was found to have acute kidney injury and hypercalcemia. On physical examination a large lower quadrant abdominal mass was palpated. Computed tomography scan of abdomen confirmed the presence of a mass along the cecum and proximal ascending colon. Colonoscopy showed a large ulcerated mass and biopsy was consistent with diffuse large B-cell lymphoma. The patient underwent colectomy but refused to receive chemotherapy.

  18. Radioimmunotherapy of Non-Hodgkin's Lymphoma. The interaction of radiation and antibody with lymphoma cells

    International Nuclear Information System (INIS)

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

    Central nervous system (CNS) involvement by lymphoma is a complication associated, almost invariably, with a poor prognosis. The knowledge of the risk factors for CNS relapse is important to determine which patients could benefit from prophylaxis. Thus, patients with very aggressive lymphomas (such as lymphoblastic lymphoma or Burkitt's lymphoma) must systematically receive CNS prophylaxis due to a high CNS relapse rate (25-30%), while in patients with indolent lymphoma (such as follicular lymphoma or marginal lymphoma) prophylaxis is unnecessary. However, the question about CNS prophylaxis in patients with diffuse large B-cell lymphoma (DLBCL), the most common type of lymphoma, remains controversial. The information available is extensive, mainly based on retrospective and heterogeneous studies. There seems that immunochemotherapy based on rituximab reduces the CNS relapse rate. On the other hand, patients with increased serum lactate dehydrogenase plus more than one extranodal involvement seem to have a higher risk of CNS relapse, but a prophylaxis strategy based only on the presence of these 2 factors does not prevent all CNS relapses. Patients with involvement of testes or breast have high risk of CNS relapse and prophylaxis is mandatory. Finally, CNS prophylaxis could be considered in patients with DLBCL and renal or epidural space involvement, as well as in those cases with MYC rearrangements, although additional studies are necessary.

    Full Text Available B-cell lymphoproliferative disorder (B-LPD is generally characterized by the proliferation of Epstein-Barr virus (EBV-infected B lymphocytes. We here report the development of EBV-negative B-LPD associated with EBV-reactivation following antithymocyte globulin (ATG therapy in a patient with aplastic anemia. The molecular autopsy study showed the sparse EBV-infected clonal T cells could be critically involved in the pathogenesis of EBV-negative oligoclonal B-LPD through cytokine amplification and escape from T-cell surveillances attributable to ATG-based immunosuppressive therapy, leading to an extremely rare B-cell-rich T-cell lymphoma. This report helps in elucidating the complex pathophysiology of intractable B-LPD refractory to rituximab.

    The preferentially expressed antigen of melanoma (PRAME), a tumor-associated antigen, is considered a prognostic marker for various human malignancies. The prognostic significance of PRAME expression for diffuse large B-cell lymphoma (DLBCL) patients treated with rituximab-containing chemotherapy has not been evaluated to date, and the ability of immunohistochemistry (IHC) to detect PRAME expression in these patients has not yet been studied, although IHC is simple to perform in clinical practice. We evaluated the prognostic significance of PRAME expression based on IHC analysis in 160 DLBCL patients treated with R-CHOP therapy. There was a significant association between higher PRAME expression and shorter progression-free survival (PFS), and a trend toward shorter overall survival (OS) in patients with higher PRAME expression than that in patients with lower PRAME expression (5-year PFS, 48.1 vs. 61.1 %; 5-year OS, 65.6 vs. 79.1 %). Patients with high PRAME expression tended to have lower chemotherapeutic responses. Thus, IHC is useful for detecting and assessing PRAME expression in DLBCL. Further, we found a positive correlation between IHC and quantitative real-time RT-PCR measurements of PRAME expression. Our findings indicate that IHC results of PRAME expression can be a novel prognostic maker in DLBCL patients treated with R-CHOP therapy. PMID:24820636

    A case of primary non-Hodgkin's lymphoma of the larynx in an AIDS patient is presented with a review of the literature. Non-Hodgkin's lymphomas in AIDS patients are common but the primary laryngeal presentation is very rare. The symptoms usually include dysphonia and progressive airway obstruction requiring tracheostomy. As with laryngeal non-Hodgkin's laryngeal lymphomas in non-HIV positive patients the majority are of B cell lineage and respond well to radiotherapy. Our patient had a high grade lymphoma of B cell lineage which showed a good response to radiotherapy. The role of chemotherapy and surgery is not yet established. We suggest that the diagnosis of AIDS should not influence the management of these patients unless the individual is in the terminal disease stage. PMID:9538453

    2016-01-01

    The hepatitis C virus (HCV) infected patients are prone to develop bone marrow or various tissue infiltrates with monoclonal B cells, monoclonal B lymphocytosis or different types of B cell non-Hodgkin’s lymphoma (BCNHL), of which the most common are splenic marginal zone BCNHL, diffuse large BCNHL and follicular lymphoma. The association between chronic HCV infection and non Hodgkin’s lymphoma has been observed especially in areas with high prevalence of this viral infection. Outside the limitations of some studies that have been conducted, there are also geographic, environmental, and genetic factors that contribute to the epidemiological differences. Various microenvironmental signals, such as cytokines, viral antigenic external stimulation of lymphocyte receptors by HCV antigens, and intercellular interactions contribute to B cell proliferation. HCV lymphotropism and chronic antigenic stimulation are involved in B-lymphocyte expansion, as mixted cryoglobulinemia or monoclonal gammopathy of undetermined significance, which can progress to BCNHL. HCV replication in B lymphocytes has oncogenic effect mediated by intracellular HCV proteins. It is also involved in an important induction of reactive oxygen species that can lead to permanent B lymphocyte damage, as DNA mutations, after binding to surface B-cell receptors. Post-transplant lymphoproliferative disorder could appear and it has a multiclonal potentiality that may develop into different types of lymphomas. The hematopoietic stem cell transplant made for lymphoma in HCV-infected patients can increase the risk of earlier progression to liver fibrosis and cirrhosis. HCV infected patients with indolent BCNHL who receive antiviral therapy can be potentially cured. Viral clearance was related to lymphoma response, fact that highlights the probable involvement of HCV in lymphomagenesis. Direct acting antiviral drugs could be a solution for the patients who did not tolerate or respond to interferon, as they

    Full Text Available Diffuse large B-cell lymphoma (DLBCL can be molecularly subtyped as either germinal center B-cell (GCB or non-GCB. The role of rituximab(R in these two groups remains unclear. We studied 204 patients with de novo DLBCL (107 treated with first-line CHOP; 97 treated with first-line R-CHOP, patients being stratified into GCB and non-GCB on the basis of BCL-6, CD10, and MUM1 protein expression. The relationships between clinical characteristics, survival data, and immunophenotype (IHC were studied. The 5-year overall survival (OS in the CHOP and R-CHOP groups was 50.4% and 66.6% (P=0.031, respectively. GCB patients had a better 5-year OS than non-GCB patients whether treated with CHOP or not (65.0% versus 40.9%; P=0.011. In contrast, there is no difference in the 5-year OS for the GCB and non-GCB with R-CHOP (76.5% versus 61.3%; P=0.141. In non-GCB subtype, additional rituximab improved survival better than CHOP (61.3% versus 40.9%; P=0.0303. These results indicated that addition of rituximab to standard chemotherapy eliminates the prognostic value of IHC-defined GCB and non-GCB phenotypes in DLBCL by improving the prognostic value of non-GCB subtype of DLBCL.

The next-generation ALK-TKI, alectinib, has been reported to have potent efficacy in ALK-positive NSCLC patients including on mutations that confer resistance to crizotinib, which was the first ALK-TKI approved for ALK-positive NSCLC. The efficacy and safety of ALK-TKIs, including crizotinib and alectinib, as the first-line treatment in critically ill patients is unclear. We report one ALK-positive NSCLC patient with poor performance status (PS) and disseminated intravascular coagulation because of respiratory failure and multiple metastases, and experienced the rapid and dramatic response to alectinib without adverse events that can lead to discontinuation and dose reduction of the drug. After a couple of months of treatment with alectinib, radiological review indicated a complete response. The present case is the first reported case of rapid and marked response to alectinib in ALK-positive NSCLC patients who had poor PS and severe organ dysfunction, such as disseminated intravascular coagulation. Further investigation of the safety and efficacy of ALK-TKI for ALK-positive NSCLC patients who are critically ill is warranted. PMID:26938871

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

    Mantle cell lymphoma (MCL) is a clinically heterogeneous non-Hodgkin lymphoma with an aggressive clinical behaviour and short survival in some cases and an indolent course in others. Advances in the biology and pathogenesis of MCL have unveiled several genes involved in deregulation of cell cycle checkpoints and the finding of subclonal populations with specific recurrent mutations (p53, ATM, NOTCH2) with an impact on disease progression and refractoriness to treatment. Prognostic stratification helps to distinguish between indolent and aggressive forms of MCL. Currently, younger fit patients benefit from more intensive front line chemotherapy regimens and consolidation with autologous transplantation, while older or frail patients are treated with less intensive regimens and rituximab maintenance. For relapsing disease, the introduction of bortezomib and lenalidomide containing regimens and B-cell receptor pathway inhibitors such as ibrutinib and idelalisib in combination with immunochemotherapy have emerged as therapeutic agents with promising clinical outcomes.

    Schnitzler syndrome is a rare condition defined by chronic urticaria, osteosclerotic bone lesions, and monoclonal IgM gammopathy. Schnitzler syndrome can precede the onset of a true lymphoproliferative disorder including Waldenström macroglobulinemia and rarely systemic marginal zone B-cell lymphoma. We describe a case of intractable chronic urticaria accompanied by a retroperitoneal neoplasm. IgM monoclonal gammopathy, lumber pain, intermittent fever, and elevation of C-reactive protein were the clues for the diagnosis of Schnitzler syndrome. An evaluation for malignancy using systemic computed tomography scan and fluorodeoxyglucose positron emission tomography revealed the retroperitoneal tumor, and a subsequent bone-marrow aspirate confirmed the diagnosis of B-cell lymphoma. Combined rituximab and radiotherapy ameliorated the skin symptoms. This case indicates that a detailed search for malignant neoplasms might be required for the long-term management of Schnitzler syndrome, and that B-cell lymphomas may contribute to the pathogenesis of this condition.

    Full Text Available Purpose of the Study: Diffuse large B-cell lymphoma (DLBCL is the most common lymphoid malignancy worldwide. Its incidence increases with age and about 40% of cases occur in patients over 70 years. Herein, we describe a case of a frail elderly patient with renal insufficiency and DLBCL treated with R-mini-CHOP. Case Report: A 77-year-old man on maintenance hemodialysis started experiencing persistent fatigue. He was diagnosed with a large mass on the left lobe of the lung. Biopsy demonstrated a DLBCL, CD20 positive. The patient was assigned clinical stage IIBX, with a high age-adjusted international prognosis index. A proper geriatric assessment revealed a frail patient. Thus, an adapted chemotherapy regimen was proposed which consisted of R-mini-CHOP every 21 days, with a reduction of 10% in the doses of doxorubicin and cyclophosphamide. During the treatment, the patient went through regular dialysis sessions, 3 times per week, with an extra session performed 12 h after each chemotherapy administration. The patient experienced no adverse events or grade 3/4 toxicities. After 6 cycles of R-mini-CHOP, the patient achieved unconfirmed complete remission, and consolidation radiotherapy was performed. At the last follow-up, he was still in unconfirmed complete remission, with a progression-free survival of 11.3 months. Conclusions: R-mini-CHOP represented a reasonable treatment option for this patient with renal failure. The oncogeriatric approach led to a successful management of this frail patient, highlighting that an adapted plan of care is a key issue to improve the outcomes of elderly cancer patients.

    Full Text Available Context: Ocular manifestations of lymphoma are rare events. Most reports of ocular involvement in lymphoma are case reports or reports of a few patients. Aims: To determine the ophthalmic disorders in adult, African, lymphoma patients. Settings and Design: A prospective study of ocular disorders in adult patients with lymphoma was conducted at the University of Benin Teaching Hospital, Benin City, Nigeria, between July 2004 and June 2007. Materials and Methods: The patients were interviewed and examined by the authors and the ocular findings recorded. Statistical Analysis: Data was analyzed on computer with the aid of the Instat GraghPad™ v2.05a statistical package software. The mean, standard deviation, Mann-Whitney U-statistic and P value were calculated. Results: A total of 111 patients with hematological malignancies were seen over a period of three years of which 62 (55.85% had lymphomas. Of these, 51(82.3% were non-Hodgkin′s lymphoma and 11(17.7% were Hodgkin′s lymphoma. Ocular disorders occurred in 16 patients (31.4% with non-Hodgkin′s lymphoma and none of the patients with Hodgkin′s lymphoma (Mann-Whitney U-statistic is equal to 7.500, U′ is equal to161.50, P , 0.0001. The ocular disorders due to non-Hodgkin′s lymphoma were seen as - proptosis in six patients (11.8%, retinopathies in three (5.9%, conjunctival infiltration in three (5.9%, optic atrophy in two (3.9%, keratoconjunctivitis in one (two per cent, desquamating nodular lid lesions in one (two per cent, papilloedema in one (two per cent, and upper lid mass in one (two per cent. Four patients (6.5% had monocular blindness. Conclusions: Ophthalmic disorders are relatively common in non-Hodgkin′s lymphoma. Ophthalmic evaluation is needed in these patients for early identification and treatment of potentially blinding conditions.

    AIM: To analyze the clinicopathologic features and the prognosis of primary intestinal lymphoma.METHODS: Patients were included in the study based on standard diagnostic criteria for primary gastrointestinal lymphoma, and were treated at Sun Yat-sen University Cancer Centre between 1993 and 2008.RESULTS: The study comprised 81 adults. The most common site was the ileocaecal region. Twenty-two point two percent patients had low-grade B-cell lymphoma.Fifty-one point nine percent patients had high-grade B-cell lymphoma and 25.9% patients had T-cell lymphoma. Most patients had localized disease. There were more patients and more early stage diseases in the latter period, and the origin sites changed. The majority of patients received the combined treatment, and about 20% patients only received nonsurgical therapy. The wverall survival and event-free survival rates after 5 years were 71.6% and 60.9% respectively. The multivariate analysis revealed that small intestine and ileocaecal region localization, B-cell phenotype, and normal lactate dehydrogenase were independent prognostic factors for better patient survival. Surgery based treatment did not improve the survival rate.CONCLUSION: Refined stratification of the patients according to the prognostic variables may allow individualized treatment. Conservative treatment may be an optimal therapeutic modality for selected patients.

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

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

    Full Text Available Abstract Introduction Sarcoidosis is a granulomatous disease that mostly involves the lungs. Its association with malignancies has been well documented. Several mechanisms have been proposed that may underlie this concurrence including triggering tumour antigens and defective cellular immunity. Case presentations We briefly review the literature on malignancy associated sarcoidosis and report two female lymphoma patients of 49 and 56 years of age who, during their course of disease, developed sarcoidosis that was misinterpreted as a lymphoma relapse on positron emission tomography-computed tomography. Conclusion We hypothesise that T cell dysfunction and exposure to tumour associated antigens might be the underlying mechanisms of development of sarcoidosis in patients with lymphoma. Positron emission tomography-positive lesions do not always indicate malignancy and therefore a tissue biopsy is always mandatory to confirm the diagnosis.

    Full Text Available Appendicular tumors are rare, and lymphoma of the appendix is rarer. A 50 - year - old female patient presented with vague abdominal discomfort and lump in the right iliac fossa. The diagnosis of diffuse large B - cell lymphoma was made after laparotomy and histopathological examination (HPE supported by immunohistochemistry study. For appendicular neoplasms diagnosed postoperatively, including lymphoma, a meticulous grossing and HPE cannot be over emphasized. In case of wall thickening of >2.50- 3 cm detected by the computed tomogram scan, the possibility of a neoplasm or lymphoma in particular should be included as the differential diagnosis irrespective of the clinical presentation

    Objective:hTis study aims to explore the clinicopathologic features of 112 patients with mantle cell lymphoma (MCL). Methods:Data from 112 MCL cases were collected, and immunohistochemical assay was conducted. Fluorescence in situ hybridization (FISH) detected a break in the CCND1 gene. hTe t-test was used in the statistical analysis. Results:All tumor cells in the 112 cases expressed B cell-related antigen, including 1 blastoid subtype and 1 polymorphic subtype. Among all cases, 106 expressed CD5 and 104 expressed cyclin D1. A break in the CCND1 gene was not found in 3 cases with CD5-MCL. IgH/CCND1 polyploid was observed in 2 classic cases. Conclusion:MCL is a type of special immunophenotypic B-cell lymphoma. hTe prognoses of blastoid and polymorphic subtypes are poor. Special subtypes should be classiifed during diagnosis.

    Full Text Available Background. Although chemotherapy added to rituximab is a standard of care for diffuse large B cell lymphoma (DLBCL, treatment of patients ≥65 years of age remains controversial due to comorbidities. Methods. This is a retrospective, comparative, nonrandomized study of patients ≥65 years of age, who were diagnosed with DLBCL but not previously treated. Demographic characteristics and comorbidities were analyzed. Three rituximab-containing treatment regimens (standard RCHOP, anthracycline dose-reduced RChOP, and RCOP were compared. Descriptive analyses were conducted. Survival was calculated with the Kaplan-Meier method, and differences were compared with the log-rank test. Results. In total, 141 patients with a median age of 73.9 years were studied. The three treatment groups had comparable demographic characteristics. The overall response was 77%, 72.5%, and 59% in groups treated with RCHOP, RChOP, and RCOP, respectively. After multivariate analysis, the factors influencing the overall survival were the presence of B symptoms, poor performance status (ECOG ≥ 3, and febrile neutropenia. Factors influencing disease-free survival were febrile neutropenia, high-intermediate and high-risk IPI scores, and treatment without anthracycline. Conclusion. A higher ORR (overall response rate was achieved with standard RCHOP, which influenced DFS and OS, although it was not statistically significant compared with the other groups. Interventional phase 3 trials testing new molecules in patients aged 70 to 80 years and older are required to improve the prognosis within this growing population.

    High-dose busulfan (Bu) is an integral component of commonly used preparative regimens for both allogeneic and autologous transplantation. There is significant interest in comparing the efficacy and toxicity of administering Bu every 6 (Bu6) or every 24 hours (daily Bu). To facilitate a therapeutic dose-monitoring protocol, we transitioned from Bu6 to daily Bu dosing for patients with Hodgkin and non-Hodgkin lymphoma undergoing autologous stem cell transplantation (ASCT). Here, we retrospectively review outcomes of 400 consecutive eligible lymphoma patients who underwent ASCT from 2007 to 2013 with high-dose busulfan (Bu), cyclophosphamide (Cy), and etoposide (E). Bu was given at a fixed dose of either .8 mg/kg every 6 hours for 14 doses for 307 patients or a fixed dose of 2.8 mg/kg every 24 hours for 4 doses (days -9 through -6) for 93 patients who underwent transplantation after the transition from Bu6 to daily Bu was made. Toxicity was assessed using pulmonary and liver function tests (LFT) at specified time points before and after ASCT. Baseline patient and disease characteristics of patients dosed with Bu6 and daily Bu were similar. There was no significant difference in forced expiratory volume in 1 second or diffusing capacity of the lungs for carbon monoxide before and after transplantation in the Bu6 versus daily Bu cohorts. Changes in LFTs with daily Bu were not significantly different than those with Bu6. There were no differences in relapse, nonrelapse mortality, progression-free survival, or overall survival between Bu6 and Bu 24 administration schedules in univariable or multivariable analysis (P ≥ .34). For a subset of 23 patients who had first-dose Bu levels measured, we observed significant variation in an median estimated cumulative area under the curve (AUC) of 17,568 µM-minute (range, 12,104 µM-23,084 µM-minute). In conclusion, daily Bu with Cy/E is more convenient than Bu6, has equivalent outcomes, and results in no increase

    Full Text Available Context: Support for non-Hodgkin′s lymphoma (NHL with large cells that is refractory or relapsed after first-line chemotherapy poses a greater therapeutic problem with bone marrow transplant therapy or when old age is a contra-indication for high-dose chemotherapy, especially among developing countries such as Algeria. Aim: To show that the regimen, including gemcitabine, could be more effective in treating elderly patients with diffuse large B-cell lymphoma (DLBCL in relapse / refractory, without complete remission, when compared with the ESHAP (etoposide, cisplatine, solumedrol, aracytine regimen. Materials and Methods: Ninety-six patients in the age group of 60-70 years were volunteers for a prospective randomized single-blind study, carried out for three years. Patients were divided into two groups by the drawing of lots. The first group (GA, n = 48, relapse; n = 27 [56.3%], refractory; n = 21 [43.7%] received treatment with ESHAP protocol and the second one (GB, n = 48, relapse; n = 28 [58%], refractory; n = 20 [42%] with GPD (gemcitabine, dexamethasone, cisplatine protocol. Results: The overall response rates and mean survival at three years were significantly higher among patients subjected to GPD treatment compared with those subjected to ESHAP treatment (63% vs. 55%, P = 0.01 and 20.5% [95% CI 16.5-24.5] vs. 11.8% [8.9-14.6], respectively. Additionally, three-year progression-free and event-free survival rates were 20.5% (16.3-24 and 19.7% (15.9-23.5, respectively, for the GPD regimen and 10.9% (8.2-13.7 and 11.1% (95% CI 8.5-13.7, respectively, for the ESHAP regimen. Moreover, the GPD regimen was associated with improving overall survival (RR=2.02, 95% CI 1.59-2.56; P = 0.000, event-free survival (2.03, 1.64-2.52; P < 0.001 and progression-free survival (1.86, 1.46-2.37; P < 0.001. Conclusion: In cases of contra-indication for high-dose chemotherapy for elderly patients with DLBCL, without complete remission, the Gemcitabine

    We report a case of visceral leishmaniasis in a 66-year-old female with a history of MALT lymphoma in the gastrointestinal tract. The patient presented with major hemorrhage per rectum and perforation of the small intestine. Due to unexplained decreasing platelets, lymphoma bone marrow involvement...... was suspected and bone marrow examination was performed. Surprisingly, Leishman-Donovan bodies were detected. The low platelet count, caused by the combination of MALT lymphoma and visceral leishmaniasis, appears to have aggravated the symptoms of the intestinal lymphoma. Leishmaniasis should be...... suspected even among asymptomatic patients with immune compromising illnesses and a travel history to areas where leishmaniasis is endemic....

    Topoisomerase (TOP) gene copy number changes may predict response to treatment with TOP-targeting drugs in cancer treatment. This was first described in patients with breast cancer and is currently being investigated in other malignant diseases. TOP-targeting drugs may induce TOP gene copy number...... chemotherapy regimens including TOP2-targeting drugs (n = 16). No TOP1 or TOP2A copy number changes were found. Polysomy of chromosomes 20 and 17 was seen in 3 of 25 patients (12%) and 2 of 32 patients (6%) with de novo DLBCL. Among relapsed patients, chromosome polysomy was more frequently observed in 5 of 13......-targeting drugs. Increased polyploidy of chromosomes 17 and 20 among patients with relapsed DLBCL may reflect genetic compensation in the tumor cells after TOP2 inhibition, but is more likely due to the increased genetic instability often seen in progressed cancers. Therefore, it is unlikely that TOP1 and...

    Central nervous system (CNS) relapse in patients with diffuse large B cell lymphoma (DLBCL) is an uncommon event, and the outcome of patients with CNS relapse is poor. However, no reliable prediction models for CNS relapse have been developed. We retrospectively analyzed consecutive de novo DLBCL patients referred to our department between September 2004 and August 2015 and treated with R-CHOP or R-CHOP-like regimens. Of 413 patients analyzed in this study, a total of 27 patients (6.5 %) eventually developed CNS relapse. The 5-year probability of CNS relapse was 8.4 %. The median time from diagnosis of DLBCL to CNS relapse was 15 months, and the median survival after CNS relapse was 7 months. In univariate analysis, the risk factors significantly associated with CNS relapse were Ann Arbor stage 3 or 4, albumin level 1, and involvement of retroperitoneal lymph node. We developed a new prognostic model consisting of these four factors. The 5-year probability of CNS relapse was significantly higher in patients with at least three of these four factors than in those with two or fewer factors (26.4 vs. 3.0 %, P < 0.001). Using this model, we evaluated the incidence and the risk factors of CNS relapse in DLBCL patients. The new risk model consisting of the four factors demonstrated good risk stratification for CNS relapse, and could help to identify high-risk patients for whom CNS prophylaxis is warranted.

    Donor T-cell immune responses can eradicate lymphomas after allogeneic hematopoietic stem cell transplantation (AHSCT), but can also damage healthy tissues resulting in harmful graft-versus-host disease (GVHD). Next-generation sequencing has recently identified many new genetic lesions in follicular lymphoma (FL). One such gene, tumor necrosis factor receptor superfamily 14 (TNFRSF14), abnormal in 40% of FL patients, encodes the herpes virus entry mediator (HVEM) which limits T-cell activation via ligation of the B- and T-lymphocyte attenuator. As lymphoma B cells can act as antigen-presenting cells, we hypothesized that TNFRSF14 aberrations that reduce HVEM expression could alter the capacity of FL B cells to stimulate allogeneic T-cell responses and impact the outcome of AHSCT. In an in vitro model of alloreactivity, human lymphoma B cells with TNFRSF14 aberrations had reduced HVEM expression and greater alloantigen-presenting capacity than wild-type lymphoma B cells. The increased immune-stimulatory capacity of lymphoma B cells with TNFRSF14 aberrations had clinical relevance, associating with higher incidence of acute GVHD in patients undergoing AHSCT. FL patients with TNFRSF14 aberrations may benefit from more aggressive immunosuppression to reduce harmful GVHD after transplantation. Importantly, this study is the first to demonstrate the impact of an acquired genetic lesion on the capacity of tumor cells to stimulate allogeneic T-cell immune responses which may have wider consequences for adoptive immunotherapy strategies.

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

    Diffuse large B-cell lymphoma (DLBCL) is an aggressive and heterogeneous malignancy harboring frequent targetable activating somatic mutations. Emerging evidence suggests that circulating cell-free DNA (cfDNA) can be used to detect somatic variants in DLBCL using Next-Generation Sequencing (NGS) experiments. In this proof-of-concept study, we chose to develop simple and valuable digital PCR (dPCR) assays for the detection of recurrent exportin-1 (XPO1) E571K, EZH2 Y641N, and MYD88 L265P mutations in DLBCL patients, thereby identifying patients most likely to potentially benefit from targeted therapies. We demonstrated that our dPCR assays were sufficiently sensitive to detect rare XPO1, EZH2, and MYD88 mutations in plasma cfDNA, with a sensitivity of 0.05%. cfDNA somatic mutation detection by dPCR seems to be a promising technique in the management of DLBCL, in addition to NGS experiments.

    Multiple lymphomatous polyposis (HLP) is an unusual form of non-Hodgkin's lymphoma characterized by polyps throughout the gastrointestinal tract. It has been reported that most MLP are observed in cases with mantle cell lymphoma of B-cell type. We herein present a case of a 66-year-old man with adult T-cell leukemia/lymphoma (ATLL). Colonoscopy revealed MLP throughout the colon and histopathological findings of ATLL cell infiltration. The patient died despite combination of chemotherapy. The literature of manifestations of colonic involvement of ATLL is reviewed and the importance of endoscopic evaluation to differentiate ATLL intestinal lesions from opportunistic infectious enterocolitis is discussed.

    Full Text Available Abstract Background HIV-negative, CD20-negative de novo diffuse large B-cell lymphoma (DLBCL patients has rarely been reported. To elucidate the nature of this entity, we retrospectively reviewed the data of 1,456 consecutive de novo DLBCL patients who were treated at Sun Yat-Sen University Cancer Center between January 1999 and March 2011. Methods The pathologic characteristics of CD20-negative patients, clinical features, response to initial treatment, and outcomes of 28 patients with available clinical data (n = 21 were reviewed. Then, a matched case-control (1:3 analysis was performed to compare patients with CD20-negative and -positive DLBCL. Results The median age of the 28 CD20-negative DLBCL patients was 48 years, with a male-female ratio of 20:8. Seventeen of 22 (77.3% CD20-negative DLBCL cases were of the non-germinal centre B-cell (non-GCB subtype. High Ki67 expression (≥80%, an index of cell proliferation, was demonstrated in 17 of 24 (70.8% cases. Extranodal involvement (≥ 1 site was observed in 76.2% of the patients. Following initial therapy, 9 of 21 (42.9% cases achieved complete remission, 4 (19% achieved partial remission, 1 (4.8% had stable disease, and 7 (33.3% had disease progression. The median overall survival was 23 months. The 3-year progression-free survival (PFS and overall survival (OS rates were 30.5% and 35%, respectively. A matched case-control analysis showed that patients with CD20-negative and -positive DLBCL did not exhibit a statistically significant difference with respect to the main clinical characteristics (except extranodal involvement, whereas the patients with CD20-positive DLBCL had a better survival outcome with 3-year PFS (P = 0.008 and OS (P = 0.008 rates of 52% and 74.1%, respectively. Conclusions This study suggests that HIV-negative, CD20-negative de novo DLBCL patients have a higher proportion of non-GCB subtype, a higher proliferation index, more frequent extranodal involvement, a poorer

    Composite lymphoma refers to the co-occurrence of two or more morphologically and immunophenotypically separate lymphomas in the same topographic site at the time of clinical presentation. It is an infrequent type of lymphoid neoplasm, present in lymphoid tissue and may be due to the existence of two genetically related neoplasms such as transformation of a single lymphoma into another more aggressive lymphoma or be due to the presence of two clonally unrelated lymphomas. This paper is presenting a case of diffuse non-Hodgkin large B-cell lymphoma with areas of low grade and high grade follicular non-Hodgkin B-cell lymphoma in a retroperitoneal lymph node and spleen of an 62 year old woman. Histopathological examination and immunohistochemistry features proved the diagnosis of composite lymphoma. PMID:25705280

    An increasing number of older patients are suffering from aggressive lymphoma. Effective and more tolerable treatment regimens are urgently needed for this growing patient population. Patients with aggressive lymphoma not eligible for anthracycline-based first-line therapy or intensive salvage regimens were treated with the rituximab-bendamustine-lenalidomide (R-BL) regimen (rituximab 375 mg/m(2)  day 1, bendamustine 70 mg/m(2)  d 1, 2, lenalidomide 10 mg d 1-21) for six cycles every 4 weeks. Forty-one patients with a median age of 75 (range 40-94) years were enrolled: 33 patients had substantial co-morbidities. 13 patients were not eligible for anthracycline-based first-line chemotherapy, 28 patients had relapsed/refractory disease. The primary endpoint, overall response, was achieved by 25 (61%) patients (95% confidence interval 45-76%). Grade ≥ 3 toxicity comprised haematological (59%), skin (15%), constitutional (15%) and neurological (12%) events. 9 patients died during trial treatment: 5 from lymphoma progression, 2 from toxicity, 2 with sudden death. After a median follow-up of 25·9 (interquartile range 20·4-31·6) months, 13 patients were still alive. Median overall survival was 14·5 months. In conclusion, R-BL can be considered a treatment option for elderly patients with treatment naïve or relapsed/refractory aggressive lymphoma not eligible for standard aggressive regimens.

    Full Text Available Cutaneous B cell lymphoma (CBCL is a lymphoproliferative disorder of neoplastic B cell of the skin with a wide range of clinical manifestations. Commonly, the clinical features of CBCL are plaques, nodules, or ulcerative lesions. Skin is one of the common sites for extra-nodal lymphomas in patients with AIDS and B cell type is less common than T cell type. Only recently, the existence of B cell lymphomas presenting clinically in the skin without evidence of extra-cutaneous involvement has been accepted as primary CBCL. Here, we are presenting 5 patients with cutaneous involvement in the setting of HIV/AIDS disease. Two of them were primary cutaneous non-Hodgkin lymphomas. All were CBCL; 3 were immunoblastic, 1 was plasmablastic, and the other was a Burkitt lymphoma. We analyzed the epidemiological, clinical, virological, and immunological characteristics of this group of patients.

    Full Text Available We report a case of a non-Hodgkin's lymphoma (NHL patient treated successfully with combination chemotherapy during pregnancy who delivered a full-term baby. A 29 year-old patient with cervical and inguinal lymphadenopathy in the 27th week of gestation was referred to our hospital. The diagnosis of lymph node biopsy was NHL (diffuse, large cell type with B-cell phenotype. Three courses of CHOP regimen (adriamycin, cyclophosphamide, vincristine and prednisolone were given before delivery. The patient has been in complete remission for three years and her baby has been in normal development. Our case supports previous reports that chemotherapy in the third trimester may be given safely on NHL patients.

    Intravascular large B-cell lymphoma (IVLBCL) is a rare variant of extranodal large B-cell lymphoma and it is characterized by selective intravascular proliferation of malignant cells. Typical features of the disease include aggressive behavior, rapid and frequently fatal course. Clinical picture is non-specific and heterogeneous, depending on the affected organ. It is not uncommon that this unique type of lymphoma is diagnosed post mortem. Herein, we report two cases of IVLBCL with neurologic symptomatology. In our clinical study patient 1 was an 80-year-old male with mixed paraparesis of lower extremities and difficulties with sphincter control. Patient 2 (56-year-old male) had vision malfunction, mental status changes and defect in phatic and motor functions. In both cases definite diagnosis was established by histological examination of necroptic material. We propose to include IVLBCL in differential diagnostic considerations in patients presenting with gradually impairing neurological status and spinal cord damage of unknown etiology (Fig. 2, Ref. 9).

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

  9. Anaplastic lymphoma kinase gene rearrangements in patients with advanced-stage non-small-cell lung cancer: CT characteristics and response to chemotherapy

    International Nuclear Information System (INIS)

    Few articles have been published on the imaging findings of anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer (NSCLC). To investigate the radiological findings of ALK-positive NSCLC in the advanced stage, CT scans were examined. In addition, the response to chemotherapy was evaluated. Of the 36 patients with ALK-rearranged NSCLC, a mass and a nodule were identified in 17 (47.2%) and 16 (44.4%), respectively, indicating that more than 40% had a small-sized tumor. Overall, 31 (86.1%) patients had lymphadenopathy, seven (19.4%) had extranodal lymph node invasion, and three (8.3%) had lymphangitis. A pleural effusion was seen in 15 patients (41.7%). All but one patient had no ground-glass opacity (GGO) lesions, indicating that most ALK-positive tumors showed a solid growth pattern without GGO on CT. Twenty were evaluable for response to chemotherapy; 10 (50.0%) had a partial response (PR), nine (45.0%) had stable disease (SD), and one (5.0%) had progressive disease (PD) with first-line chemotherapy. With second-line chemotherapy, five (26.3%) had PR, 11 (57.9%) had SD, and three (15.8%) had PD. The five patients with PR were all treated by using crizotinib. Time to progression was 8.2 months with first-line chemotherapy, and 6.0 months with second-line chemotherapy. Advanced-stage ALK-positive tumors have a relatively aggressive phenotype, which cannot be inferred from the size of the tumor alone. ALK-positive patients have a good response to first-line cytotoxic drugs and to crizotinib as second-line therapy, but a relatively poor response to cytotoxic drugs as second-line therapy

    Predictive value (PV) of surveillance fluorodeoxyglucose positron emission tomography (FDG-PET) in patients with diffuse large B-cell lymphoma (DLBCL) treated with chemotherapy-rituximab (R) versus chemotherapy only, remains unclear. The aim of the current study was to compare the performance of surveillance PET in DLBCL patients receiving CHOP (cyclophosphamide, hydroxydaunorubicin hydrochloride, vincristine, and prednisone) alone versus CHOP-R. Institutional database was retrospectively searched for adults with newly diagnosed DLBCL, receiving CHOP or CHOP-R, who achieved complete remission and underwent surveillance PETs. Follow-up (FU) PET was considered positive for recurrence in case of an uptake unrelated to physiological or known benign process. Results were confirmed by biopsy, imaging and clinical FU. One hundred nineteen patients, 35 receiving CHOP and 84 CHOP-R, who underwent 422 FU-PETs, were analyzed. At a median PET-FU of 3.4 years, 31 patients relapsed (17 vs. 14, respectively; P = 0.02). PET detected all relapses, with no false-negative studies. Specificity and positive PV (PPV) were significantly lower for patients receiving CHOP-R vs. CHOP (84% vs. 87%, P = 0.023; 23% vs. 74%, P CHOP-R (77% vs. 26%, P < 0.001). In the latter group, FP-rate remained persistently high up to 3 years post-therapy. Multivariate analysis confirmed rituximab to be the most significant predictor for FP-PET. In conclusion, routine surveillance FDG-PET is not recommended in DLBCL treated with rituximab; strict criteria identifying patients in whom FU-PET is beneficial are required. PMID:23423884

    Introduction:The rearrangement of the anaplastic lymphoma kinase (ALK) gene accounts for approximately 1%–6%of lung adenocarcinoma cases and deifnes a molecular subgroup of tumors characterized by clinical sensitivity toALK inhibitors such as crizotinib. This study aimed to identify the relationship betweenALK rearrangement and the clinico‑pathologic characteristics of non‑small cell lung cancer (NSCLC) and to analyze the therapeutic responses of crizotinib and conventional chemotherapy toALK rearrangement in NSCLC patients. Methods:A total of 487 lung cancer patients who underwent testing forALK rearrangement in our department were included in this study.ALK rearrangement was examined by using lfuorescence insitu hybridization (FISH) assay. Results:Among the 487 patients, 44 (9.0%) were diagnosed withALK rearrangement by using FISH assay. In 123 patients with adenocarcinoma who were non‑smokers and of a young age (≤58years old), the frequency ofALK rearrangement was 20.3% (25/123). Short overall survival (OS) was associated with non‑adenocarcinoma tumor type (P=0.006), poorly differentiated tumors (P=0.001), advanced‑stage tumors (P<0.001), smoking history (P=0.008), and wild‑type epidermal growth factor receptor (EGFR) (P=0.008). Moreover, patients with poorly differentiated and advanced‑stage tumors had a shorter time to cancer progression compared with those with well differentiated (P=0.023) and early‑stage tumors (P=0.001), respectively. Conclusions:ALK‑rearranged NSCLC tends to occur in younger individuals who are either non‑smokers or light smokers with adenocarcinoma. Patients withALK rearrangement might beneift fromALK inhibitor therapy.

    Diffuse large B-cell lymphoma is the most common type of non-Hodgkin's lymphoma. More than 50% of patients have some site of extra-nodal involvement at diagnosis,including the gastrointestinal tract and bone marrow.However, a diffuse large B-cell lymphoma presenting as acute pancreatitis is rare. A 57-year-old female presented with abdominal pain and matted lymph nodes in her axilla. She was admitted with a diagnosis of acute pancreatitis. Abdominal computed tomography (CT) scan showed diffusely enlarged pancreas due to infiltrative neoplasm and peripancreatic lymphadenopathy. Biopsy of the axillary mass revealed a large B-cell lymphoma.The patient was classified as stage Ⅳ, based on the Ann Arbor Classification, and as having a high-risk lymphoma,based on the International Prognostic Index. She was started on chemotherapy with CHOP (cyclophosphamide,doxorubicin, vincristine and prednisone). Within a week after chemotherapy, the patient's abdominal pain resolved. Follow-up CT scan of the abdomen revealed a marked decrease in the size of the pancreas and peripancreatic lymphadenopathy. A literature search revealed only seven cases of primary involvement of the pancreas in B-cell lymphoma presenting as acute pancreatitis. However, only one case of secondary pancreatic involvement by B-cell lymphoma presenting as acute pancreatitis has been published. Our case appears to be the second report of such a manifestation.Both cases responded well to chemotherapy.

  13. Mild Toxicity and Favorable Prognosis of High–Dose and Extended Involved-Field Intensity-Modulated Radiotherapy for Patients With Early-Stage Nasal NK/T-Cell Lymphoma

    International Nuclear Information System (INIS)

    Purpose: The value of intensity-modulated radiotherapy (IMRT) for early-stage nasal NK/T-cell lymphoma has not been previously reported. The aim of the present study was to assess the dosimetric parameters, toxicity, and treatment outcomes of patients with nasal NK/T-cell lymphoma. Methods and Materials: Between 2003 and 2008, 42 patients with early-stage nasal NK/T-cell lymphoma underwent definitive high-dose and extended involved-field IMRT with or without combination chemotherapy. The median radiation dose to the primary tumor was 50 Gy. The dose–volume histograms of the target volume and critical normal structures were evaluated in all patients. The locoregional control, overall survival, and progression-free survival were calculated using the Kaplan-Meier method. Results: The average mean dose delivered to the planning target volume was 55.5 Gy. Only 1.3% and 2.5% of the planning target volume received <90% and 95% of the prescribed dose, respectively, indicating excellent planning target volume coverage. The mean dose and average dose to the parotid glands was 15 Gy and 14 Gy, respectively. With a median follow-up time of 27 months, the 2-year locoregional control, overall survival, and progression-free survivalrate was 93%, 78%, and 74%, respectively. No Grade 4 or 5 acute or late toxicity was reported. Conclusions: High-dose and extended involved-field IMRT for patients with early-stage nasal NK/T-cell lymphoma showed favorable locoregional control, overall survival, and progression-free survival, with mild toxicity. The dose constraints of IMRT for the parotid glands can be limited to <20 Gy in these patients.

  14. MYC expression in concert with BCL2 and BCL6 expression predicts outcome in Chinese patients with diffuse large B-cell lymphoma, not otherwise specified.

    Full Text Available Recent studies provide convincing evidence that a combined immunohistochemical or fluorescence in situ hybridization (FISH score of MYC, BCL2, BCL6 proteins and MYC translocations predicted outcome in diffuse large B-cell lymphoma (DLBCL patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP. However, by far, all these researches are based on Western populations. Therefore, we investigate the prognostic relevance of MYC-, BCL2- and BCL6-rearrangements and protein expression by immunohistochemistry and FISH from 336 de novo DLBCL, NOS treated with CHOP or R-CHOP. Breaks in MYC and BCL6, and fusion in IGH/BCL2 were detected in 9.7%, 20.0%, and 11.1% of the cases, respectively, and were not significantly associated with clinical outcomes. Protein overexpression of MYC (≥40%, BCL2 (≥70% and BCL6 (≥50% was encountered in 51%, 51% and 36% of the tumors, respectively. On the basis of MYC, BCL2 and BCL6 expression, double-hit scores (DHSs and triple-hit score (THS were assigned to all patients with DLBCL. Patients with high MYC/BCL2 DHS, high MYC/BCL6 DHS and high THS had multiple adverse prognostic factors including high LDH level, poor performance status, advanced clinical stage, high International Prognostic Index (IPI score, and non-germinal center B-cell. In univariate analysis, high MYC/BCL2 DHS, high MYC/BCL6 DHS and high THS were associated with inferior OS and PFS in both CHOP and R-CHOP cohorts (P0.05. These data together suggest that the immunohistochemical DHSs and THS defined a large subset of DLBCLs with double-hit biology and was strongly associated with poor outcome in patients treated with R-CHOP or CHOP.

    Primary central nervous system (CNS) lymphomas are relatively rare with the most common subtype being diffuse large B-cell lymphoma. Primary CNS T-cell lymphomas (PCNSTL) account for 1 mutation, and none showed overlapping mutations. These included mutations in DNMT3A, KRAS, JAK3, STAT3, STAT5B, GNB1, and TET2 genes, genes implicated previously in other T-cell neoplasms. The outcome was heterogenous; 2 patients are alive without disease, 4 are alive with disease, and 6 died of disease. In conclusion, PCNSTLs are histologically and genomically heterogenous with frequent phenotypic aberrancy and a cytotoxic phenotype in most cases. PMID:26379152

    Mantle cell lymphoma (MCL) exhibits considerable molecular heterogeneity and complexity, and is regarded as one of the most challenging lymphomas to treat. With increased understanding of the pathobiology of MCL, it is proposed that MCL is the result of 3 major converging factors, namely, deregulated cell cycle pathways, defects in DNA damage responses, and dysregulation of cell survival pathways. In the present era of targeted therapies, these biologic insights have resulted in the identification of several novel rational targets for therapeutic intervention in MCL that are undergoing active clinical testing. To date, there is no standard of care in MCL. Several approaches including conventional anthracycline-based therapies and intensive high-dose strategies with and without stem cell transplantation have failed to produce durable remissions for most patients. Moreover, considering the heterogeneity of MCL, it is increasingly being recognized that risk-adapted therapy might be a relevant therapeutic approach in this disease. At the first and second Global Workshops on Mantle Cell Lymphoma, questions addressing advances in the pathobiology of MCL, optimization of existing therapies, assessment of current data with novel therapeutic strategies, and the identification of molecular or phenotypic risk factors for utilization in risk-adapted therapies were discussed and will be summarized herein.

    A 27-year-old man with the autoimmune lymphoproliferative syndrome and a large-B-cell lymphoma had heterozygous mutations in the Fas and perforin (Prf1) genes. The Fas mutation was inherited from his healthy father and was also carried by his healthy brother, whereas the Prf1 mutation was inherited from his healthy mother. The combined effect of the two mutant genes may have contributed to the development of the autoimmune lymphoproliferative syndrome and lymphoma in this patient. PMID:15459303

    Full Text Available Introduction. Sometimes it is not easy to clinically recognize subtle differences between intraocular lymphoma and noninfectious uveitis. The most common lymphoma subtype involving the eye is B-cell lymphoma. Case report. We presented two patients aged 59 and 58 years with infiltration of the subretinal space with a large B-cell non-Hodgkin intraocular lymphoma. The patients originally had clinically masked syndrome in the form of intermediate uveitis. As it was a corticosteroid-resistant uveitis, we focused on the possible diagnosis of neoplastic causes of this syndrome. During hospitalization, the neurological symptoms emerged and multiple subretinal changes accompanied by yellowish white patches of retinal pigment epithelium with signs of vitritis, which made us suspect the intraocular lymphoma. Endocranial magnetic resonance imaging established tumorous infiltration in the region of the left hemisphere of the cerebellum. The histopathological finding confirmed the diagnosis of large B-cell non-Hodgkin lymphoma of risk moderate degree, immunoblast - centroblast cytological type. The other patient had clinical chronic uveitis accompanied by yellowish shaped white echographic changes of the retina and localized changes in the level of the subretina. The diagnosis of lymphoma was made by brain biopsy. Conclusion. Uveitis masquerade syndrome should be considered in all patients over 40 years with idiopathic steroid-resistant uveitis. Treatment begun on time can affect the course and improve the prognosis of uveitis masquerade syndrome (UMS and systemic disease.

    Full Text Available Non-Hodgkin′s lymphoma (NHL is the second most common acquired immunodeficiency syndrome (AIDS-defining cancer. In this population, up to 70-80% of cases may present as extranodal location as the primary clinical manifestation of the neoplasm disease. Gastrointestinal tract is the most frequent location of AIDS-associated NHL. However, salivary gland involvement, including the parotid gland is a rare complication in human immunodeficiency virus (HIV-patients. Here, we describe a patient seropositive for the HIV, who developed a primary NHL of the parotid gland histologically classified as a high-grade diffuse large B-cell lymphoma. Patient was treated with a combination of chemotherapy plus highly active antiretroviral therapy with a good clinical, virological and immunological response and a prolonged survival, more than 5 years, without evidence of neoplasm relapse.

  2. Value of Surveillance Studies for Patients With Stage I to II Diffuse Large B-Cell Lymphoma in the Rituximab Era

    International Nuclear Information System (INIS)

    Background: The role of surveillance studies in limited-stage diffuse large B-cell lymphoma (DLBCL) in the rituximab era has not been well defined. We sought to evaluate the use of imaging (computed tomography [CT] and positron emission tomography [PET]-CT) scans and lactate dehydrogenase (LDH) in surveillance of patients with stage I to II DLBCL. Methods: A retrospective analysis was performed of patients who received definitive treatment between 2000 and 2013. Results: One hundred sixty-two consecutive patients with stage I to II DLBCL were treated with chemotherapy +/− rituximab, radiation, or combined modality therapy. The 5-year rates of overall survival (OS) and freedom from progression (FFP) were 81.2% and 80.8%, respectively. Of the 162 patients, 124 (77%) were followed up with at least 1 surveillance PET scan beyond end-of-treatment scans; of those, 94 of 124 (76%) achieved a complete metabolic response on PET scan after completion of chemotherapy, and this was associated with superior FFP (P=.01, HR=0.3) and OS (P=.01, HR 0.3). Eighteen patients experienced relapse after initial response to therapy. Nine relapses were initially suspected by surveillance imaging studies (8 PET, 1 CT), and 9 were suspected clinically (5 by patient-reported symptoms and 4 by symptoms and physical examination). No relapses were detected by surveillance LDH. The median duration from initiation of treatment to relapse was 14.3 months among patients with relapses suspected by imaging, and 59.8 months among patients with relapses suspected clinically (P=.077). There was no significant difference in OS from date of first therapy or OS after relapse between patients whose relapse was suspected by imaging versus clinically. Thirteen of 18 patients underwent successful salvage therapy after relapse. Conclusions: A complete response on PET scan immediately after initial chemotherapy is associated with superior FFP and OS in stage I to II DLBCL. The use of PET scans as

    Full Text Available Abstract Background B-cell lymphomas are thought to reflect different stages of B-cell maturation. Based on cytogenetics and molecular markers, mantle cell lymphoma (MCL is presumed to derive predominantly from naïve, pre-germinal centre (pre-GC B lymphocytes. The aim of this study was to develop a method to investigate the similarity between MCL cells and different B-cell compartments on a protein expression level. Methods Subpopulations of B cells representing the germinal centre (GC, the pre-GC mantle zone and the post-GC marginal zone were isolated from tonsils using automated magnetic cell sorting (AutoMACS of cells based on their expression of CD27 and IgD. Protein profiling of the B cell subsets, of cell lines representing different lymphomas and of primary MCL samples was performed using top-down proteomics profiling by surface-enhanced laser detection/ionization time-of-flight mass spectrometry (SELDI-TOF-MS. Results Quantitative MS data of significant protein peaks (p-value Conclusion AutoMACS sorting generates sufficient purity to enable a comparison between protein profiles of B cell subpopulations and malignant B lymphocytes applying SELDI-TOF-MS. Further validation with an increased number of patient samples and identification of differentially expressed proteins would enable a search for possible treatment targets that are expressed during the early development of MCL.

  5. Prognostic significance of interim 18F-FDG PET/CT SUV reduction associated with Ki67 in patients with diffuse large B-cell lymphoma

    International Nuclear Information System (INIS)

    To detect the prognostic significance of interim 18F-FDG PET/CT SUV (standard uptake value) reduction (ΔSUVmax) associated with Ki67 in patients with diffuse large B cell lymphoma (DLBCL). 47 DLBCL patients underwent PET/CT before initiation and after 2-4 cycles of chemotherapy were included. The SUVmax of the dominant lesions were calculated. Ki67 positive indices were provided by enzyme-labeled immunohistochemistry. SPSS17.0 was used for statistical analysis. ΔSUVmax of different groups were compared by t test. Receiver-operator characteristic analysis was performed to determine the optimal cutoff values. Kaplan- Meier analyses of PFS (Progression-free survival) were compared using log-rank test. The average of ΔSUVmax and ΔSUVmax% were 11.53 and 69.10%, respectively. The optimal cutoff values of ΔSUVmax and ΔSUVmax% were 11.45 and 82.92%, respectively. Higher ΔSUVmax and ΔSUVmax% indicated longer PFS (p<0.001). The optimal cutoff value of Ki67 was 55%. Ki67 ≥55% was revealed to be an indicator of shorter PFS (p=0.019). Either ΔSUVmax<11.45 or Ki67>55% was defined as an indicator to poor outcome and scored 1 point. The PFS rate was 100% in patients scored 0 point, yet 0% in patients scored 2 points. PFS tended to be shorter along with the score getting higher (p=0.006). ΔSUVmax and Ki67 positive index were both of significance in DLBCL prognosis. The prognostic value may be confirmed when ΔSUVmax was accordant with Ki67. (authors)

    Full Text Available Posttransplant lymphoproliferative disorder (PTLD is a potentially fatal complication of solid organ transplantation. The majority of PTLD is of B-cell origin, and 90% are associated with the Epstein-Barr virus (EBV. Lymphomatoid granulomatosis (LG is a rare, EBV-associated systemic angiodestructive lymphoproliferative disorder, which has rarely been described in patients with renal transplantation. We report the case of a patient with renal transplantation for SLE, who presented, 9 months after renal transplantation, an EBV-associated LG limited to the intracranial structures that recovered completely after adjustment of her immunosuppressive treatment. Nine years later, she developed a second PTLD disorder with central nervous system initial manifestation. Workup revealed an EBV-positive PTLD Burkitt lymphoma, widely disseminated in most organs. In summary, the reported patient presented two lymphoproliferative disorders (LG and Burkitt's lymphoma, both with initial neurological manifestation, at 9 years interval. With careful reduction of the immunosuppression after the first manifestation and with the use of chemotherapy combined with radiotherapy after the second manifestation, our patient showed complete disappearance of neurologic symptoms and she is clinically well with good kidney function. No recurrence has been observed by radiological imaging until now.

    International Nuclear Information System (INIS)

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

    Full Text Available Objective: PMBCL is a distinct type of nonhodgkins lymphoma with specific clinicopathological features. To clarify clinical features, treatment alternatives and outcomes, we evaluated 28 Arab patients treated with chemotherapy or radiotherapy between 2006 and 2011. Patients and Methods: PMBCL lymphoma patients identified according to WHO classification and treated at KCCC between 2006 and 2011 were included in this study. Demographic and clinical data are presented as means or medians. Overall survival was estimated using the Kaplan-Meier method. Survival rates were compared using the log-rank test. A P < 0.05 was considered significant. Results: The median age of the patients was 31 years and the male to female ratio was 2:1. Majority of the patients (75% presented with stage I/II disease. Most had features of local extension like pleural effusion (18% and SVCO (39%. Only 11% of the patients had bone marrow involvement at presentation. 96% of the patients required biopsy from the mediastinal mass either by image guided core biopsy (75% or by surgical biopsy. Most patients were treated by RCHOP and involved field radiotherapy. Patients with positive PET scan after RCHOP chemotherapy received salvage chemotherapy and BEAM autologous marrow transplant. The five year OS for the entire group was 85% while the PFS was 73%. Patients who had PET scan for response evaluation had better OS [P = 0.013] and PFS [P = 0.039] when compared with those patients who received only radiotherapy based on CT scan evaluation. Conclusion: PMBCL is a specific lymphoma entity seen in the young with good survival. The role of PET scan for response evaluation and the type of consolidation therapy needs to be further clarified

    We report a case of Burkitt lymphoma of the jaws in an immunocompetent adolescent, revealed by intraoral swelling. An orthopantomogram showed multiple osteolytic lesions. Biopsy revealed Burkitt lymphoma. The disease was treated with chemotherapy. Complete remission was attained 15 months after the end of treatment. Burkitt lymphomas accounts for 30-40% of all non-Hodgkin lymphomas in children, with diagnosis confirmed by histology. Immunophenotyping completes the diagnosis by identifying the presence of B markers. Chemotherapy is currently the main treatment of BL, because of the high chemosensitivity of the tumor and its low radiosensitivity. Overall survival in localized stages is close to 100%.

    Full Text Available Testicular lymphoma is the second most common extra nodal lymphomas. It is a highly lethal disease with a median survival of 1-2 years. In human immunodeficiency virus (HIV patients, primary testicular lymphomas are estimated to comprise > 6% of testicular tumors, and they tend to occur in younger patients. Testicular lymphoma can occasionally be the initial manifestation of the disease in HIV patients.Plasmablastic lymphoma (PBL, which is considered as a variant of diffuse large B-cell lymphoma is a highly aggressive tumor with poor prognosis. PBL has a well-established association with HIV infection and occurs most commonly in the oral cavity. The presentation at extra nodal sites and absence of usual hematolymphoid markers makes its diagnosis more difficult. PBL of the testis as the primary lesion in HIV patients has not been reported so far. We report a case of PBL presenting as a primary testicular lesion in a HIV patient with a grave prognosis.

    2015-09-01

    Hepatosplenic T-cell lymphoma is a rare, aggressive T-cell lymphoma, characterized by hepatosplenic sinusoidal infiltration of monotonous, medium-sized, nonactivated cytotoxic T cells, usually of γ/δ T-cell receptor type. Hepatosplenic T-cell lymphoma occurs more frequently in immunocompromised patients, especially in those receiving long-term immunosuppressive therapy. Patients usually manifest hepatosplenomegaly without lymphadenopathy. The bone marrow is also involved in two-thirds of cases and is often accompanied by circulating lymphoma cells, which, along with anemia and thrombocytopenia, may raise suspicion for acute leukemia. The differential diagnosis includes aggressive natural killer-cell leukemia, T-large granular lymphocytic leukemia, T-lymphoblastic leukemia, enteropathy-associated T-cell lymphoma type II, primary cutaneous γ/δ T-cell lymphoma, other peripheral T-cell lymphomas, myelodysplastic syndrome, and infectious mononucleosis. The diagnosis is usually established from the combination of clinical findings, histologic features, and immunophenotype, although cytogenetic/molecular studies are occasionally needed. Hepatosplenic T-cell lymphoma exhibits a dismal clinical course with a poor response to currently available therapies. PMID:26317456

SOX11 is both a diagnostic and prognostic antigen, and may potentially be used for treatment selection for younger patients, in relation to protocols including high dose chemotherapy. The molecular pathways involved are still not fully elucidated and, as SOX11 can interact with several co-transcription factors, functional assays need to be carefully designed to pinpoint SOX11-specific function in a defined cellular context. Furthermore, as SOX11 belongs to a large family of homologous proteins, analysis of SOX11 has been limited by the availability of specific antibodies for detection and pull-down. In this review, we discuss the emerging role of SOX11 in mantle cell lymphoma and discuss the potential impact in relation to tumorigenesis, diagnostics, prognostics, and therapy.

    Full Text Available Background: Rituximab in combination with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP significantly prolonged event-free survival in first-line chemotherapy for patients with diffuse large B-cell lymphoma (DLBCL. But relapse and refractory DLBCL occur frequently. Although rituximab is effective, its role in salvage therapy after autologous transplant remains unclear. Maintenance therapy with rituximab in responding patients after first line chemotherapy may be a useful novel approach capable of eradicating minimal residual disease and to bring survival benefit. This systematic review and meta-analysis evaluated the effects of rituximab maintenance treatment and salvage therapy of patients with DLBCL. Methods: We performed a systematic review and meta-analysis of randomized controlled trials and compared rituximab maintenance or salvage therapy at relapse with observation. We searched the Cochrane Library, PubMed, EMBASE, conference proceedings, databases of ongoing trials, and references of published trials. Two reviewers independently assessed the quality of the trials and extracted data. Hazard ratios for time-to-event data were estimated and pooled.

    Background:Rituximab in combination with cyclophosphamide,doxorubicin,vincristine,and prednisone (CHOP) significantly prolonged event-free survival in first-line chemotherapy for patients with diffuse large B-cell lymphoma (DLBCL).But relapse and refractory DLBCL occur frequently.Although rituximab is effective,its role in salvage therapy after autologous transplant remains unclear.Maintenance therapy with rituximab in responding patients after first line chemotherapy may be a useful novel approach capable of eradicating minimal residual disease and to bring survival benefit.This systematic review and meta-analysis evaluated the effects of rituximab maintenance treatment and salvage therapy of patients with DLBCL.Methods:We performed a systematic review and meta-analysis of randomized controlled trials and compared rituximab maintenance or salvage therapy at relapse with observation.We searched the Cochrane Library,PubMed,EMBASE,conference proceedings,databases of ongoing trials,and references of published trials.Two reviewers independently assessed the quality of the trials and extracted data.Hazard ratios for time-to-event data were estimated and pooled.Results:Seven trials including 1470 DLBCL patients were included in this systematic review and meta-analysis.Patients treated with maintenance rituximab have better overall survival (OS) and event-free survival (EFS) than patients in the observation arm,but there was no statistical significance.Patients who received rituximab salvage therapy for relapse or refractory DLBCL have statistically significantly better OS [HR of death =0.72,95% CI (0.55-0.94),P=0.02],progression-free survival (PFS) [HR =0.61,95% CI (0.52-0.72),P< 0.05],odds ratio (OR) [RR =1.26,95% CI (1.07-1.47),P =0.004] than patients in the observation arm.The rate of infection-related adverse events was higher with rituximab treatment [RR =1.37,95% CI =(1.14-1.65) P =0.001].Conclusions:After first-line chemotherapy,the two rituximab

    Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a distinct Hodgkin lymphoma subtype composed of few neoplastic lymphocyte-predominant (LP) cells in a background of reactive small B and T cells. We have seen occasional NLPHL cases that contain background T cells with prominent cytologic atypia, raising the differential diagnosis of peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) or a composite lymphoma. We sought to characterize the clinicopathologic features of such cases. Eleven NLPHL cases with atypical T cells diagnosed from 1977 to 2010 were identified at 2 institutions and compared with 24 control NLPHL cases lacking atypical T cells. All 9 male patients and 2 female patients presented with localized peripheral lymphadenopathy. In comparison with control patients, they were younger (median age, 13.8 vs. 36.1 y; P=0.015), with more frequent cervical lymph node involvement (54.5% vs. 8.3%, P=0.015). In all 11 cases, areas of NLPHL with typical B-cell-rich nodules containing LP cells were present. Nine cases contained sheets of atypical T cells surrounding primary and secondary follicles in a pattern mimicking the T-zone pattern of PTCL-NOS; the remaining 2 cases contained atypical T cells presented as large clusters at the periphery of B-cell-rich nodules. In all cases, the atypical T-cell-rich areas contained rare scattered LP cells, which were IgD in 5 of 7 cases (71.4%). The atypical T cells showed no pan-T-cell antigen loss or aberrant T-cell antigen expression in any case, and polymerase chain reaction or Southern blot analysis showed no evidence of T-cell clonality in 6 cases tested. The atypical T cells exhibited a variable immunophenotype with respect to germinal center, follicular T-helper, T-regulatory, and cytotoxic T-cell markers. Among 8 patients with clinical follow-up (median follow-up: 6.4 y), 5 patients had recurrent NLPHL at 6 months to 12 years after diagnosis and 6 patients are alive without disease at 9 months to 18

    Full Text Available Background: Systemic anaplastic large cell lymphoma (ALCL accounts for 2-8% of non-Hodgkin′s lymphoma in adults and 10-15% in children. While there is ample data in the world literature about the clinical features and outcome of this disease, prognosis in Indian patients is largely unknown. Objective: To study the clinical, pathologic profile and outcome ALCL. Materials and Methods: Fifty patients who had pathologically proven diagnosis of systemic ALCL at our institute from June 2003 to May 2011 were included for retrospective analysis. This included 30 cases of anaplastic lymphoma kinase+ (ALK+, ALCL and 20 cases of anaplastic lymphoma kinase- (ALK−, ALCL. The hospital protocol for treatment of these patients included CHOP chemotherapy regimen in >15 years of age and MCP842 protocol with vinblastine for 1 year in <15 years of age. Event free survival was noted. These outcomes were correlated with ALK status, International Prognostic Index (IPI score, and stage at presentation. Results: At a median follow-up of 36 months (range: 6-72 months ALK− ALCL had a poor outcome. The 3 year event free survival in pediatric ALCL was 66.7%. In adults, this was 60% ALK+ ALCL was 60% and 20% in ALK− ALCL. Conclusions: Systemic ALCL is an aggressive disease. CD3 + positivity is commonly seen in ALK− ALCL and ALK+, epithelial membrane antigen + positivity is seen in ALK+ ALCL. ALK− ALCL, advanced stage III, IV and high IPI score were associated with poor prognosis. The demographic profile and outcome in our study was similar to the world literature. With new drugs like crizotinib and brentuximab vedotin the future looks very promising.

    Full Text Available Mantle cell lymphoma (MCL is a subtype of B-cell non-Hodgkin′s lymphoma seen predominantly in males. Common extra-nodal sites of involvement of MCL are Waldeyer′s ring, gastrointestinal tract, bone marrow and peripheral blood. The extra-nodal palatal localization of MCL is quite uncommon. MCL is seen in predominantly older patients, therefore undiagnosed MCL patients are likely to have total prosthesis. In this study, a case of MCL, initially presenting as palatal swelling was reported with relevant literature review and the possible role of dental professionals in the diagnosis of this rare entity was discussed.

    Full text: The aim of this prospective study was to asses the value of new radioimmunotherapy treatment with Zevalin (IgG1 monoclonal antibody covalently bound to tiuxetan and labeled with Y-90) for adult patients with refractory or relapsed CD20+ follicular B-cell non- Hodgkin's lymphoma (NHL). This multicentric study included eight patients (median age 55 years, range 51-59 years) from five hospitals in Croatia. The treatment involved a day 1 infusion of rituximab 250 mg /m2; a second infusion of rituximab on day 8, followed by 'slow push' 10 minute infusion of Zevalin (median dose 1020 MBq; range 820- 1177 MBq). On follow-up 12 weeks after treatment response was achieved in six patients (75%). In three patients tumor mass was completely disappeared (complete response), and in other three patients tumor mass was significantly decreased (partial response). Hematological toxicity was observed in three patients and manifested with infections requiring hospitalization. One patient died because of extreme pancytopenia and Candida sepsis, in spite of support with granulocyte colony-stimulating factor. The median time to lowest blood counts was four weeks after Zevalin injection. Acute and non-hematological side effects were not observed. Our preliminary results confirmed Zevalin as a very effective therapy for patients with refractory or relapsed CD20+ follicular B-cell NHL. One should be aware of hematologic toxicity; therefore the close follow-up is required. (author)

    B cell lymphoma (BCL) has a higher degree of malignancy and complicated pathogenic mechanism. Regulatory T cells (Treg cells) are known to exert certain immune suppression functions, in addition to immune mediating effects. Recent studies have revealed the role of Treg cells in pathogenesis and progression of multiple malignant tumors. This study therefore investigated the functional role and related mechanism of Treg cells in BCL. A cohort of thirty patients who were diagnosed with BCL in our hospital between January 2013 and December 2014. Another thirty healthy individuals were recruited. Peripheral blood mononuclear cells (PBMCs) were separated and analyzed for the ratio of CD4+/CD25+ Treg cells. The mRNA expression levels of Foxp3, transforming growth factor (TGF)-β1 and interleukin (IL)-10 genes were quantified by real-time PCR, while their serum levels were determined by enzyme-linked immunosorbent assay (ELISA). Meanwhile all laboratory indexes for patients were monitored during the complete remission (CR) stage. BCL patients significantly elevated ratio of CD4+/CD25+ Treg cells, which were decreased at CR stage. mRNA levels of Foxp3, TGF-β1 and IL-10, in addition to protein levels of TGF-β1 and IL-10 were potentiated in lymphoma patients but decreased in CR patients (Pregulating cytokines, thereby facilitating the pathogenesis and progression of lymphoma.

    Despite a wide spectrum of treatment options, mantle cell lymphoma (MCL) remains a challenging hematologic malignancy to manage. Advances in front-line therapy, including the monoclonal antibody rituximab and increasing use of cytarabine, have improved remission rates. Autologous hematopoietic cell transplantation (HCT) can effectively consolidate remission of MCL, leading to encouraging survival beyond 5 yr. However, nearly all patients with MCL will relapse and require salvage therapy. Novel agents such as ibrutinib, bortezomib, and lenalidomide have dramatically expanded the options for treating relapsed MCL. In this review, we summarize the clinical evidence supporting the use of allogeneic donor HCT in MCL and make recommendations on indications for its use. Data suggest that allogeneic donor HCT is the only curative therapy for patients with poor prognosis or aggressive MCL. Patient selection, timing, and optimal use remain a matter of scientific debate and given the rapidly changing therapeutic landscape of MCL, the outcomes of allogeneic HCT should be interpreted in the context of novel therapeutics.

    Sphingosine-1-phosphate (S1P) is a potent lipid mediator that is produced during the metabolism of sphingolipid by sphingosine kinase. S1P has been implicated in the migration and trafficking of lymphocytes and several lymphoid malignancies through S1P receptors. Moreover, the overexpression of sphingosine-1-phosphate receptor 1 (S1PR1) has been correlated with the constitutive activation of signal transducer and activator of transcription (STAT)3 and poor prognosis of diffuse large B-cell lymphoma (DLBCL). Thus, in this study, we examined the expression of S1PR1 in 198 DLBCL samples collected from nodal and various extranodal sites and sub-classified formalin-fixed paraffin-embedded tissue samples into germinal centre B-cell-like (GCB) and non-GCB subgroups using immunohistochemistry. These analyses showed S1PR1 overexpression in 15·7% of all cases with DLBCL and in 54·2% of 24 cases with primary testicular (PT)-DLBCL; S1PR1 expression correlated with S1PR1mRNA expression and STAT3 phosphorylation in fresh samples. Analyses of data from a single institution suggested that S1PR1 overexpression was an independent negative prognostic marker in 68 patients with DLBCL of clinical stages I and II. The present high prevalence of S1PR1 overexpression warrants the consideration of PT-DLBCL as a distinct disease subtype and suggests the potential of the S1P/S1PR1 axis as a therapeutic target.

To study the clinicopathological profile of BCLu-DLBCL/BL. Cross-sectional study over 3 year period in the Haematology section of Department of Pathology in a large teaching hospital in Southern India from January 2011 to December 2013. All the cases reported as BCLu-DLBCL/BL were collected and the clinical, morphological and immunohistochemical parameters were analyzed. Descriptive statistics. There were seven cases, four males and three females, of age ranging from 20 to 70 years. Five cases had extranodal involvement. Four cases had Burkitt morphology with strong Bcl2 positivity and absent CD10 expression. One case had the morphology and immunophenotype that of typical BL, along with strong positivity to Bcl2 suggesting a double hit hypothesis. Two cases had morphology and immunophenotype of BL with low Ki 67. Three patients on follow up had adverse outcome. BCLu-DLBCL/BL, a provisional category in WHO 2008 is useful in classifying the cases not meeting the criteria for classical BL or DLBCL. Each of these cases was interesting with different sites of involvement, different morphological features and immunophenotype with most of the patients on follow up ending with a grave prognosis.

    A case of angioimmunoblastic T-cell lymphoma (AITL) which was misdiagnosed as adult Still's disease was presented. The clinical and laboratory characteristics of this case and related literatures were analyzed and reviewed. The patient was finally diagnosed as AITL (Ann Arbor classification: Stage IIIB) secondary to cranial astrocytoma (WHO classification: Stage III), complicated with severe pulmonary infection because of long time treatment of corticosteroid and misdiagnosis (about one and a half year). It is concluded that AITL is a rare disease which was easily misdiagnosed. The diagnosis of AITL should combine the clinical manifestation with pathological biopsy as well as corresponding immunohistochemical tests.

Except for a positive DNA test for Epstein-Barr virus (EBV) infection, extensive diagnostic workup for infections, malignancy, or a neurological cause was negative. Mixing studies revealed a nonspecific inhibitor of PT and PTT but Factor VIII levels were normal. The patient was empirically treated with antibiotics but developed hypotension and died on day 27 of admission. At autopsy, patient was found to have intravascular diffuse large B-cell lymphoma involving skin, testes, lung, and muscles. The malignant cells were positive for CD20, CD791, Mum-1, and Pax-5 and negative for CD3, CD5, CD10, CD30, and Bcl-6. The malignant cells were 100% positive for Ki-67. Discussion. Intravascular large cell B-cell lymphoma (IVLBCL) is rare form of diffuse large B-cell lymphoma and tends to proliferate within small blood vessels, particularly capillaries and postcapillary venules. The cause of its affinity for vascular bed remains unknown. In many reports, IVLBCL was associated with HIV, HHV8, and EBV infections. The fact that our case showed evidence of EBV infection lends support to the association of this diagnosis to viral illness. The available literature on this subject is scant, and in many cases, the diagnosis was made only at autopsy. The typical presentation of this disorder is with B symptoms, progressive neurologic deficits, and skin findings. Bone marrow, spleen, and liver are involved in a minority of patients. Nearly all patients have elevated LDH, and about 65% are

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

    Primary T-cell lymphomas of the central nervous system (CNS) are uncommon, but aggressive and increasing in incidence. We describe a rare case of T-cell lymphoma in a cerebellar location, to our knowledge the first reported case demonstrating gamma/delta receptor expression. Additionally, we elaborate on key diagnostic features and review all nine patients with primary CNS lymphoma of cytotoxic T-cell phenotype reported in the literature. A 26-year-old female medical student presented with a 6week history of nausea, vomiting and dizziness. MRI revealed a 2cm cerebellar mass. The tumor was subtotally resected, and pathologic examination of a subtotal resection specimen demonstrated peripheral T-cell lymphoma, not otherwise specified, with a gamma/delta cytotoxic T-cell phenotype. She subsequently started high dose methotrexate and cytarabine. We report a unique case of primary CNS gamma delta CD8+ T-cell lymphoma lineage in a young female patient. While these are rare entities, it is an important differential diagnosis to consider. Therapy should be tailored to the patient, and involves resection with adjuvant chemotherapy, radiotherapy or autologous stem-cell based treatments. PMID:26804925

    To further explore the role of rituximab when added to the CHOP-like regimen in the treatment of immunohistochemically defined non-germinal center B-cell subtype (non-GCB) diffuse large B-cell lymphoma (DLBCL),159 newly diagnosed DLBCL patients were studied retrospectively based on the immunohistochemical evaluation of CD10,Bcl-6,MUM-1,and Bcl-2.Altogether,110 patients underwent the CHOP-like regimen,and rituximab was added for the other 49 patients.Cox regression analysis showed that compared with the CHOP-like regimen,the rituximab-based regimen (R-CHOP regimen)significantly decreased the risk of disease relapse and progression in CD10-negative patients (P =0.001),Bcl-6-negative patients (P =0.01),and MUM-1-positive patients (P =0.003).The risk of disease relapse in patients with non-GCB subtype (P =0.002) also decreased.In contrast,patients with the opposite immunohistochemical marker expression profile and GCB subtype did not benefit from treatment with the R-CHOP regimen.In addition,non-GCB subtype patients had a significantly higher expression rate of Bcl-2than GCB subtype patients (P =0.042).Although univariate analysis found that both Bcl-2-positive and -negative patients had significantly higher event-free survival rates with the R-CHOP regimen,only Bcl-2positivity (P =0.004) maintained significance in the Cox regression analysis.We conclude that the addition of rituximab can significantly improve the prognosis of patients with non-GCB subtype DLBCL,which is closely related to the expression of CD10,Bcl-6,MUM-1,and Bcl-2.

    Full Text Available Abstract Introduction Diffuse large B-cell lymphoma is a diffuse proliferation of large neoplastic B lymphoid cells with a nuclear size equal to or exceeding the normal macrophage nuclei. We report a case of a clear cell variant of diffuse large B-cell lymphoma involving a lymph node in the neck, which was clinically suspected of being metastatic carcinoma. Case presentation A 39-year-old Caucasian ethnic Albanian man from Kosovo presented with a rapidly enlarging lymph node in his neck, but he also disclosed B symptoms and fatigue. A cytological aspirate of the lymph node revealed pleomorphic features. Our patient underwent a cervical lymph node biopsy (large excision. The mass was homogeneously fish-flesh, pale white tissue replacing almost the whole structure of the lymph node. The lymph node biopsy showed a partial alveolar growth pattern, which raised clinical suspicion that it was an epithelial neoplasm. With regard to morphological and phenotypic features, we discovered large nodules in diffuse areas, comprising large cells with slightly irregular nuclei and clear cytoplasm admixed with a few mononuclear cells. In these areas, there was high mitotic activity, and in some areas there were macrophages with tangible bodies. Staining for cytokeratins was negative. These areas had the following phenotypes: cluster designation marker 20 (CD20 positive, B-cell lymphoma (Bcl-2-positive, Bcl-6-, CD5-, CD3-, CD21+ (in alveolar patterns, prostate-specific antigen-negative, human melanoma black marker 45-negative, melanoma marker-negative, cytokeratin-7-negative and multiple myeloma marker 1-positive in about 30% of cells, and exhibited a high proliferation index marker (Ki-67, 80%. Conclusion According to the immunohistochemical findings, we concluded that this patient has a clear cell variant of diffuse large B-cell lymphoma of activated cell type, post-germinal center cell origin. Our patient is undergoing R-CHOP chemotherapy treatment.

    A 41-year-old male patient with a history of ankylosing spondylitis and Crohn disease, treated with immunomodulators and disease-modifying drugs, was diagnosed with a primary intestinal T-cell lymphoma that followed a 7.5-year-course. This transmural proliferation lacked cytological characteristics of anaplastic large cell lymphoma (ALCL), and was CD8-positive, and CD30- and anaplastic lymphoma kinase (ALK)-negative by immunohistochemistry (IHC). However, ALK-gene rearrangement (ALK-gr) was detected by fluorescence in situ hybridization (FISH) in both initial and persistent disease. The possibility of indolent T-cell lymphoproliferative disease of the gastrointestinal tract with atypical features (transmural involvement) related to ALK-gr was suggested. A previous case of aggressive 'enteropathy-associated ALCL' in the context of celiac disease was recently reported, which also lacked anaplastic morphology, and where CD30 and ALK expression was incidentally demonstrated by IHC, and ALK-gr subsequently confirmed by FISH. These two recent cases represent two distinct rare entities pertaining to the group of primary intestinal T-cell lymphomas, and they both show unexpected ALK-gr. This suggests that ALK-gr has been overlooked in the group of primary intestinal T-cell lymphomas. Performing IHC and FISH tests for ALK-gr in primary gastrointestinal T-cell lymphomas might be of importance, particularly with the advancement of targeted therapy that could impact treatment and prognosis.

    Introduction:Hepatitis B virus (HBV) reactivation has been reported in B-cel lymphoma patients with resolved hepatitis B (hepatitis B surface antigen [HBsAg]-negative and hepatitis B core antibody [HBcAb]-positive). This study aimed to assess HBV reactivation and hepatitis occurrence in diffuse large B-cel lymphoma (DLBCL) patients with resolved hepatitis B receiving rituximab-containing chemotherapy compared with HBsAg-negative/HBcAb-negative patients to identify risk factors for HBV reactivation and hepatitis occurrence and to analyze whether HBV reactivation and hepatitis affect the survival of DLBCL patients with resolved hepatitis B. Methods:We reviewed the clinical data of 278 patients with DLBCL treated with rituximab-containing therapy between January 2004 and May 2008 at Sun Yat-sen University Cancer Center, China. Predictive factors for HBV reactivation, hepatitis development, and survival were examined by univariate analysis using the chi-square or Fisher’s exact test and by multivariate analysis using the Cox regression model. Results:Among the 278 patients, 165 were HBsAg-negative. Among these 165 patients, 6 (10.9%) of 55 HBcAb-positive (resolved HBV infection) patients experienced HBV reactivation compared with none (0%) of 110 HBcAb-negative patients (P=0.001). Patients with resolved hepatitis B had a higher hepatitis occurrence rate than HBsAg-negative/HBcAb-negative patients (21.8%vs. 8.2%, P=0.013). HBcAb positivity and elevated baseline alanine aminotransferase (ALT) levels were independent risk factors for hepatitis. Among the 55 patients with resolved hepatitis B, patients with elevated baseline serum ALT or aspartate aminotransferase (AST) levels were more likely to develop hepatitis than those with normal serum ALT or AST levels (P=0.037, P=0.005, respectively). An elevated baseline AST level was an independent risk factor for hepatitis in these patients. Six patients with HBV reactivation recovered after immediate antiviral therapy, and

  13. MicroRNA signatures in B-cell lymphomas

    International Nuclear Information System (INIS)

    Accurate lymphoma diagnosis, prognosis and therapy still require additional markers. We explore the potential relevance of microRNA (miRNA) expression in a large series that included all major B-cell non-Hodgkin lymphoma (NHL) types. The data generated were also used to identify miRNAs differentially expressed in Burkitt lymphoma (BL) and diffuse large B-cell lymphoma (DLBCL) samples. A series of 147 NHL samples and 15 controls were hybridized on a human miRNA one-color platform containing probes for 470 human miRNAs. Each lymphoma type was compared against the entire set of NHLs. BL was also directly compared with DLBCL, and 43 preselected miRNAs were analyzed in a new series of routinely processed samples of 28 BLs and 43 DLBCLs using quantitative reverse transcription-polymerase chain reaction. A signature of 128 miRNAs enabled the characterization of lymphoma neoplasms, reflecting the lymphoma type, cell of origin and/or discrete oncogene alterations. Comparative analysis of BL and DLBCL yielded 19 differentially expressed miRNAs, which were confirmed in a second confirmation series of 71 paraffin-embedded samples. The set of differentially expressed miRNAs found here expands the range of potential diagnostic markers for lymphoma diagnosis, especially when differential diagnosis of BL and DLBCL is required

    Full Text Available A small subset of patients with nodular lymphocyte-predominant Hodgkin’s lymphoma (NLPHLs develop a non-Hodgkin lymphoma either concurrently or subsequently, usuallyT-cell/histiocyte-rich B-cell lymphomas (T/HRBCL, which are subtypes of diffuse large B-cell lymphomas (DLBCL. The standard treatment of DLBCL patients is rituximab-based chemotherapy with cyclophosphamide, adriamycin, vincristine and prednisolone. However, the administration of this chemotherapy regimen to patients with DLBCL arising in NLPHL brings concern about the cardiac toxicity of anthracycline because the majority of these patients had already received anthracycline-based chemotherapy with doxorubicin, bleomycin, vinblastine and dacarbazine at the time of NLPHL. Herein, we report 2 patients with sequential transformation of NLPHL to T/HRBCL. They initially presented with limited-stage NLPHL and subsequently developed T/HRBCL after 16 and 8 months, respectively. At the time of T/HRBCL, they were treated with rituximab, ifosfamide, carboplatin and etoposide, and complete responses were obtained.

    Primary cutaneous peripheral T-cell lymphomas (PTL), unspecified, are rare lymphomas, with a poor prognosis. They grow and disseminate rapidly, leading to widespread disease. We report a case of PTL, unspecified occurring on the nose. Despite its aggressive histology, this tumour behaved indolently. It is remarkably similar, clinically and histologically, to four recently described cases that occurred on the ear.

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

    International Nuclear Information System (INIS)

    The improvement on the treatment of malignant lymphoma have led to prolonged survival for many patients. However, they are at risk of late complications of the disease and treatment. Impaired function due to radiation-induced injury of normal tissues, such as cardiac, pulmonary, or thyroid dysfunction, becoming manifest at few months to years after treatment. Fortunately, only a small portion of these are major complications, causing severe, or permanent disability. The frequency of secondary leukemia (AML) occurring in patients treated for malignant lymphoma is highest in those patients receiving many courses of combination chemotherapy and is low in those receiving radiation therapy alone.

    Peripheral T cell lymphomas are rare in young patients. We report the first case of a follicular variant of peripheral T cell lymphoma not otherwise specified in an 11-year-old boy, who presented with a large mediastinal mass. Microscopic examination of the mediastinal biopsy revealed nodular infiltration of medium- to large-sized atypical lymphocytes. Immunohistochemistry showed expression of follicular helper T cell markers (CD10, PD1, CXCL13, and BCL6) in tumor T cells. Epstein-Barr virus (EBV) was not detected by an in situ hybridization assay for EBV-encoded RNA. Interestingly, fluorescence in situ hybridization detected the presence in the tumor cells of the t(5;9)(q33;q22) translocation, involving ITK and SYK rearrangement. T cell clonality was detected by multiplex PCR analysis of TRG and TRD gene rearrangements. After 4 cycles of systemic chemotherapy, the patient was in complete remission. Although this entity is very rare, our observations show that lymphomas arising from T follicular helper cells may occur in children and that this should be distinguished from other lymphomas, such T-lymphoblastic lymphomas, which require a specific therapeutic approach.

  2. Controversies in autologous and allogeneic hematopoietic cell transplantation in peripheral T/NK-cell lymphomas.

    Shustov, Andrei

    2013-03-01

    Peripheral T-cell and NK-cell lymphomas (PT/NKCL) are a heterogeneous group of lymphoid neoplasms with poor outcomes. There is no consensus on the best front line therapy or management of relapsed/refractory disease. The use of autologous and allogeneic hematopoietic cell transplantation (HCT) has been studied in both settings to improve outcomes. Multiple retrospective and several prospective trials were reported. While at first sight the outcomes in the relapsed/refractory setting appear similar in B-cell and T-cell lymphomas when treated with high dose therapy (HDT) and autologous HCT, it is becoming obvious that only specific subtypes of PTCL benefit from this approach (i.e. anaplastic large cell lymphoma [ALCL] and angioimmunoblastic lymphoma [AITL] in second CR). In less favorable histologies, HDT seems to provide limited benefit, with the majority of patients experiencing post-transplant relapse. The use of autologous HCT to consolidate first remission has been evaluated in several prospective trials. Again, the best results were observed in ALCL, but the superiority of this approach over chemotherapy alone needs confirmation in randomized trials. In less favorable histologies, high-dose consolidation resulted in low survival rates comparable to those obtained with chemotherapy alone, and without randomized trials it is hard to recommend this strategy to all patients with newly diagnosed PT/NKCL. Allogeneic HCT might provide potent and potentially curative graft-vs-lymphoma effect and overcome chemotherapy resistance. Only a few studies have been reported to date on allogeneic HCT in PT/NKCL. Based on available data, eligible patients benefit significantly from this approach, with 50% or more patients achieving long-term disease control or cure, although at the expense of significant treatment related mortality (TRM). Reduced-intensity conditioning regimens appear to have lower TRM and might extend this approach to older patients. With the recent approval of

    BACKGROUND: ASCO and EORTC guidelines recommend granulocyte colony-stimulating factor (G-CSF) primary prophylaxis for cancer patients with a ≥20% overall risk of febrile neutropenia (FN), and to support delivery of dose-dense regimens. CHOP-like regimens (with rituximab [R]) are the current...... standard of care for the management of aggressive non-Hodgkin lymphoma (NHL), but they are often associated with significant myelosuppression. Neutropenic events, particularly febrile neutropenia (FN), can be life-threatening and may lead to dose delays or reductions that compromise the efficacy of......-CSF primary prophylaxis. Across all cycles, 29% of R-CHOP-21 patients had an unplanned hospitalization, with neutropenia/FN being the main reason. Subsequently, 67% of patients achieved a relative dose intensity (RDI) of ≥90% of their planned treatment (with respect to cyclophosphamide, doxorubicin, and...

    Burkitt lymphoma is a highly aggressive non-Hodgkin lymphoma that is characterized by MYC deregulation. Recently, the PI3K pathway has emerged as a cooperative prosurvival mechanism in Burkitt lymphoma. Despite the highly successful results of treatment that use high-dose chemotherapy regimens in pediatric Burkitt lymphoma patients, the survival rate of pediatric patients with progressive or recurrent disease is low. PI3Ks are also known to regulate cell migration, and abnormal cell migration may contribute to cancer progression and dissemination in Burkitt lymphoma. Little is known about Burkitt lymphoma cell migration, but the cooperation between MYC and PI3K in Burkitt lymphoma pathogenesis suggests that a drug combination could be used to target the different steps involved in Burkitt lymphoma cell dissemination and disease progression. The aim of this study was to investigate the effects of the histone deacetylase inhibitor suberoylanilide hydroxamic acid combined with the PI3K inhibitor LY294002 on Burkitt lymphoma cell growth and migration. The combination enhanced the cell growth inhibition and cell-cycle arrest induced by the PI3K inhibitor or histone deacetylase inhibitor individually. Moreover, histone deacetylase inhibitor/PI3K inhibitor cotreatment suppressed Burkitt lymphoma cell migration and decreased cell polarization, Akt and ERK1/2 phosphorylation, and leads to RhoB induction. In summary, the histone deacetylase inhibitor/PI3Ki combination inhibits cell proliferation and migration via alterations in PI3K signaling and histone deacetylase activity, which is involved in the acetylation of α-tubulin and the regulation of RhoB expression.

  12. Microenvironment-Centred Dynamics in Aggressive B-Cell Lymphomas

    Full Text Available Aggressive B-cell lymphomas share high proliferative and invasive attitudes and dismal prognosis despite heterogeneous biological features. In the interchained sequence of events leading to cancer progression, neoplastic clone-intrinsic molecular events play a major role. Nevertheless, microenvironment-related cues have progressively come into focus as true determinants for this process. The cancer-associated microenvironment is a complex network of nonneoplastic immune and stromal cells embedded in extracellular components, giving rise to a multifarious crosstalk with neoplastic cells towards the induction of a supportive milieu. The immunological and stromal microenvironments have been classically regarded as essential partners of indolent lymphomas, while considered mainly negligible in the setting of aggressive B-cell lymphomas that, by their nature, are less reliant on external stimuli. By this paper we try to delineate the cardinal microenvironment-centred dynamics exerting an influence over lymphoid clone progression in aggressive B-cell lymphomas.

    NK/T cell lymphoma, nasal type is an aggressive and uncommon malignancy. Disease that occurs outside of the aerodigestive tract exhibits an even more aggressive clinical behaviour and does not respond as well to conventional therapy compared to its nasal counterpart. We report such a case of NK/T cell lymphoma, nasal type, that presented as an anterior chest wall mass, arising from the left pectoralis muscle. An interesting feature we wish to highlight is the associated eosinophilia that corresponded to disease activity, exhibiting fluctuations with surgical resection and chemotherapy. To the best of our knowledge this is the third reported case of NK/T cell lymphoma that is associated with peripheral eosinophilia. Our case highlights the role of certain NK cell subsets that play a major role in eosinophilic activation in NK/T lymphomas and calls for more research into further classification of this disease by virtue of its NK cell subsets.

    2016-08-01

    Bortezomib is a first in class proteasome inhibitor, initially approved by the US Food and Drug Administration for the treatment of plasma cell myeloma. Bortezomib has been approved for the treatment of relapsed and refractory mantle cell lymphoma (MCL) and, more recently, in the upfront setting as well. Treatment algorithms for MCL have rapidly evolved over the past two decades, and the optimal regimen remains to be defined. The choice of treatment regimen is based on disease risk stratification models, the expected toxicity of antineoplastic agents, the perceived patient ability to tolerate the planned treatments and the availability of novel agents. As new drugs with novel mechanisms of action and variable toxicity profiles come into use, treatment decisions for a given patient have become increasingly complex. This article provides an overview of the evolving use of bortezomib in the rapidly changing management landscape of MCL. PMID:27493710

    2012-05-01

    Full Text Available The discovery by Morris SW et al. in 1994 of the genes contributing to the t(2;5(p23;q35 translocation has put the foundation for a molecular based recognition of Anaplastic Large Cell Lymphoma (ALCL and pointed out the need for a further stratification of T-cell neoplasia. Likewise the detection of ALK genetic lesions among many human cancers has defined unique subsets of cancer patients, providing new opportunities for innovative therapeutic interventions. The objective of this review is to appraise the molecular mechanisms driving ALK-mediated transformation, and to maintain the neoplastic phenotype. The understanding of these events will allow the design and implementation of novel tailored strategies for a well-defined subset of cancer patients.

    Full Text Available The authors revise the concept of anaplastic large cell lymphoma (ALCL in the light of the recently updated WHO classification of Tumors of Hematopoietic and Lymphoid Tissues both on biological and clinical grounds. The main histological findings are illustrated with special reference to the cytological spectrum that is indeed characteristic of the tumor. The phenotype is reported in detail: the expression of the ALK protein as well as the chromosomal abnormalities is discussed with their potential pathogenetic implications. The clinical features of ALCL are presented by underlining the difference in terms of response to therapy and survival between the ALK-positive and ALK-negative forms. Finally, the biological rationale for potential innovative targeted therapies is presented.

    An update at 7 years was conceived for our multicenter phase II study in which 55 elderly high-risk untreated diffuse large B-cell lymphoma patients were treated with (90)Y-ibritumomab tiuxetan after a short course of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP) as long-term follow-up analyses of this combined therapeutic modality are lacking. The overall response rate to the entire regimen was 80%, including 73% (40/55) of complete response (CR) rate and 7% (4/55) of partial response rate. At the time of writing, 24/55 (43.6%) patients experienced a progression disease and 20 of 40 (50%) patients who obtained a CR are still alive in continuous CR. With a median follow-up of 7 years, the disease-free survival was 43.3% and the progression-free survival was 36.1%. The overall survival at 7.9 years was 38.9% (27 deaths mainly because of lymphoma). Two patients developed secondary hematological malignancies, an acute myeloid leukemia and a myelodysplastic syndrome, at 4 and 3 years from radioimmunotherapy, respectively. Our data confirm the feasibility, efficacy and safety of four cycles of R-CHOP followed by radioimmunotherapy consolidation even in the long term: this combination allows dispensing less chemotherapy in a frail group of patients without invalidating response quality and duration.

    Full Text Available Subcutaneous panniculitis-like T-cell lymphoma is a distinct variant of cutaneous T-cell lymphoma, characterized by primary involvement of the subcutaneous fat in a manner mimicking panniculitis. It accounts for less than one percent of all non Hodgkin lymphoma. We describe two such patients who presented with cutaneous nodules. A 28 year old male presented with a one and a half month history of multiple subcutaneous nodules over the thighs, abdominal wall and chest. A clinical diagnosis of panniculitis was made. An excision biopsy of one the nodules was performed and the histopathology revealed subcutaneous panniculitis-like T-cell lymphoma. The other patient was a 44 year old male who underwent excision of a subcutaneous mass in the right thigh and on histopathological examination a diagnosis of subcutaneous panniculitis-like T-cell lymphoma was made. The patients received one cycle of CHOP (cyclophoshamide, vincristine, doxorubicin and prednisolone regimen, followed by systemic steroids and were advised follow up.

    2015-01-01

    Full Text Available Primary Cutaneous Peripheral T-Cell Lymphoma NOS (PTL-NOS is a rare, progressive, fatal dermatologic disease that presents with features similar to many common benign plaque-like skin conditions, making recognition of its distinguishing features critical for early diagnosis and treatment (Bolognia et al., 2008. A 78-year-old woman presented to ambulatory care with a single 5 cm nodule on her shoulder that had developed rapidly over 1-2 weeks. Examination was suspicious for malignancy and a biopsy was performed. Biopsy results demonstrated CD4 positivity, consistent with Mycosis Fungoides with coexpression of CD5, CD47, and CD7. Within three months her cancer had progressed into diffuse lesions spanning her entire body. As rapid progression is usually uncharacteristic of Mycosis Fungoides, her diagnosis was amended to PTL-NOS. Cutaneous T-Cell Lymphoma (CTCL should be suspected in patients with patches, plaques, erythroderma, or papules that persist or multiply despite conservative treatment. Singular biopsies are often nondiagnostic, requiring a high degree of suspicion if there is deviation from the anticipated clinical course. Multiple biopsies are often necessary to make the diagnosis. Physicians caring for patients with rapidly progressive, nonspecific dermatoses with features described above should keep more uncommon forms of CTCL in mind and refer for early biopsy.

    Full Text Available Abstract Background Most lymphomas that involve the tonsil are large B cell lymphomas. Large B-cell lymphoma is a high grade malignancy which progresses rapidly. Tonsillar lymphoma usually presents as either a unilaterally enlarged palatine tonsil or as an ulcerative and fungating lesion over the tonsillar area. Small lymphocytic lymphomas (SLL of the Waldeyer's ring are uncommon. Case presentation We report a 41-year-old male who presented with a ten-year history of snoring. Physical examination revealed smooth bilateral symmetrically enlarged tonsils without abnormal surface change or cervical lymphadenopathy. Palatal redundancy and a narrowed oropharyngeal airway were also noted. The respiratory disturbance index (RDI was 66 per hour, and severe obstruction sleep apnea (OSA was suspected. No B symptoms, sore throat, odynophagia or dysphagia was found. We performed uvulopalatopharyngoplasty (UPPP and pathological examination revealed incidental small B-cell lymphocytic lymphoma (SLL. Conclusion It is uncommon for lymphoma to initially present as OSA. SLL is an indolent malignancy and is not easy to detect in the early stage. We conclude that SLL may be a contributing factor of OSA in the present case.

There is a high relapse rate with conventional cytotoxic chemotherapy. Intensive combination chemotherapy including rituximab, dose intense CHOP- (cyclophosphamide-doxorubicin-vincristine-prednisone like regimens, high dose cytarabine, and/or consolidation with autologous stem cell transplant (autoSCT have shown promise in significantly prolonging remissions. Data from phase II studies show that even in patients with chemotherapy refractory MCL, allogeneic stem cell transplant (alloSCT can lead to long term disease control. Most patients with MCL are not candidates for myeloablative alloSCT due to their age, comorbidities, and performance status. The advent of less toxic reduced intensity conditioning (RIC regimens, which rely more on the graft-versus-lymphoma (GVL effect, have expanded the population of patients who would be eligible for alloSCT. RIC regimens alter the balance of toxicity and efficacy favoring its use. Treatment decisions are complicated by introduction of novel agents which are attractive options for older, frail patients. Further studies are needed to determine the role and timing of alloSCT in MCL. Currently, for selected fit patients with chemotherapy resistant MCL or those who progress after autoSCT, alloSCT may provide long term survival.Keywords: mantle cell lymphoma, allogeneic SCT, nonmyeloablative, GVL

    Full Text Available Abstract Background A relatively high incidence of pathological conditions in retrieved femoral heads, including a group of patients having low grade B-cell lymphoma, has been described before. At short term follow up none of these patients with low-grade B-cell lymphoma showed evidence of systemic disease. However, the long term follow up of these patients is not known. Methods From November 1994 up to and including December 2005 we screened all femoral heads removed at the time of primary total hip replacement histopathologically and included them in the bone banking protocol according to the guidelines of the American Associations of Tissue Banks (AATB and the European Association of Musculo-Skeletal Transplantation (EAMST. We determined the percentage of B-cell lymphoma in all femoral heads and in the group that fulfilled all criteria of the bone banking protocol and report on the long-term follow-up. Results Of 852 femoral heads fourteen (1.6% were highly suspicious for low-grade B-cell lymphoma. Of these 852 femoral heads, 504 were eligible for bone transplantation according to the guidelines of the AATB and the EAMST. Six femoral heads of this group of 504 were highly suspicious for low-grade B-cell lymphoma (1.2%. At long term follow up two (0.2% of all patients developed systemic malignant disease and one of them needed medical treatment for her condition. Conclusion In routine histopathological screening we found variable numbers of low-grade B-cell lymphoma throughout the years, even in a group of femoral heads that were eligible for bone transplantation. Allogenic transmission of malignancy has not yet been reported on, but surviving viruses are proven to be transmissible. Therefore, we recommend the routine histopathological evaluation of all femoral heads removed at primary total hip arthroplasty as a tool for quality control, whether the femoral head is used for bone banking or not.

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the efficacy and side effects of radioimmunotherapies with Zevalin (RIT-Z) in Japanese patients with low-grade B-cell non-Hodgkin lymphoma (NHL). Sixty-two patients with NHL were enrolled. Based on histology, 49 of the patients had follicular lymphoma and 23 had other lesions. The response was assessed at 8-12 weeks after RIT-Z injection with positron emission tomography (PET)/CT. The overall response rate was 85%. Thirty-seven (60%) patients achieved complete remission, 16 (26%) had partial remission, 4 (6%) had stable disease, and 5 (8%) had progressive disease. There was a significant correlation between the response to RIT-Z, frequency of chemotherapy, and history of prior treatment with fludarabine. There was no significant difference in efficacy according to lymphoma type, years since last chemotherapy, patient age, or disease stage at RIT-Z. Thrombocytopenia of grade 4 was significantly correlated with disease stage at RIT-Z and history of prior treatment with fludarabine. There was also no significant correlation between hematotoxicity and lymphoma type, frequency of chemotherapy, years since last chemotherapy, patient age, or history of bone marrow transplant. Anemia was significantly correlated with frequency of chemotherapy, history of bone marrow transplant, and history of prior treatment with fludarabine. The response rate was high, and we were able to decrease the hematologic side effects by using RIT-Z earlier. (author)

    Full Text Available A 55-year-old HIV-negative white male presented with right ear deafness, right axillary lymphadenopathy, and weight loss. Laboratory findings included anemia, marked leukocytosis, and thrombocytopenia. Examination of the peripheral smear demonstrated the presence of increased circulating blast-like cells of intermediate size, with basophilic cytoplasm and nuclei with open chromatin. MRI of the brain was compatible with hemorrhagic labyrinthitis. Excisional biopsy of the axillary mass revealed an enlarged lymph node with effaced architecture and “starry sky” appearance. The cells expressed CD20, CD10, BCL6, and surface kappa immunoglobulin light chain, with a high proliferative index by immunohistochemistry and flow cytometry. Subsequent bone marrow biopsy was hypercellular (approximately 95%, with blast-like cells virtually replacing all hematopoietic elements. Routine karyotype as well as FISH analysis of bone marrow cells demonstrated rearrangement of the MYC gene at chromosome 8q24 region, IGH/MYC fusion, and additional signal for IGH gene. We present herein a case of sporadic Burkitt lymphoma occurring in a previously healthy HIV-negative male. The unusual clinical findings in this case include the relatively older age at presentation (55 years, an immunocompetent patient who had nodal involvement and leukemic phase of Burkitt, coupled with partial deafness. A brief educational review of this neoplasm is made.

    Primary bone lymphoma(PBL) is a rare disease. To assess the clinical characteristics, outcome, and prognostic factors of this entity in Chinese population, we retrospectively analyzed 61 PBL patients initially treated in our institution between 1997 and 2014. The median age was 45 years. The most common histological subtype was diffuse large B-cell lymphoma (DLBCL) (55.7%), followed by T-cell lymphoma (18.0%). All patients underwent systemic chemotherapy as initial treatment while 24 patients (39.3%) were additionally treated with radiotherapy. The 5-year overall survival (OS) and the 5-year progression-free survival (PFS) rates of 57 cases with completed follow-up were 52.3% and 40.1%, respectively. In further analysis of the primary bone DLBCL (PB-DLBCL) subgroup, the 5-year OS and PFS rates were 53.0% and 47.0%, and a multivariable analysis revealed that baseline Eastern Cooperative Oncology Group (ECOG) score and response to initial treatment (complete remission versus no complete remission) were independent prognostic factors for both OS and PFS. The proportion of T-cell lymphoma is higher in China than in western populations. High baseline ECOG scores (≥2) and unachieved CR in initial therapy were factors for poor PB-DLBCL prognosis. The role of radiotherapy and rituximab in PLB therapy remains to be confirmed in further investigation. PMID:27357354

    The gut is the most common extranodal site where lymphomas arise. Although all histological lymphoma types may develop in the gut, small and large B-cell lymphomas predominate. The sometimes unexpected finding of a lymphoid lesion in an endoscopic biopsy of the gut may challenge both the clinician (who is not always familiar with lymphoma pathogenesis) and the pathologist (who will often be hampered in his/her diagnostic skill by the limited amount of available tissue). Moreover, the past 2 d...

    Whole-body imaging, in particular molecular imaging with fluorine 18 ((18)F)-fluorodeoxyglucose (FDG) positron emission tomography (PET), is essential to management of lymphoma. The assessment of disease extent provided by use of whole-body imaging is mandatory for planning appropriate treatment and determining patient prognosis. Assessment of treatment response allows clinicians to tailor the treatment strategy during therapy if necessary and to document complete remission at the end of treatment. Because of rapid technical developments, such as echo-planar sequences, parallel imaging, multichannel phased-array surface coils, respiratory gating, and moving examination tables, whole-body diffusion-weighted (DW) magnetic resonance (MR) imaging that reflects cell density is now feasible in routine clinical practice. Whole-body DW MR imaging allows anatomic assessment as well as functional and quantitative evaluation of tumor sites by calculation of the apparent diffusion coefficient (ADC). Because of their high cellularity and high nucleus-to-cytoplasm ratio, lymphomatous lesions have low ADC values and appear hypointense on ADC maps. As a result, whole-body DW MR imaging with ADC mapping has become a promising tool for lymphoma staging and treatment response assessment. The authors review their 4 years of experience with 1.5-T and 3-T whole-body DW MR imaging used with (18)F-FDG PET/computed tomography at baseline, interim, and end of treatment in patients with Hodgkin lymphoma and diffuse large B-cell lymphoma and discuss the spectrum of imaging findings and potential pitfalls, limitations, and challenges associated with whole-body DW MR imaging in these patients.

    Full Text Available Primary mediastinal B-cell lymphoma (PMBCL is an uncommon aggressive subset of diffuse large B-cell lymphomas. Although PMBCL frequently spreads locally from the thymus into the pleura or pericardium, it rarely invades directly through the heart. Herein, we report a case of a young Mexican female diagnosed with PMBCL with clear infiltration of lymphoma through the cardiac wall and into the right atrium and tricuspid valve leading to tricuspid regurgitation. This was demonstrated by cardiac MRI and transthoracic echocardiogram. In addition, cardiac MRI and CT scan of the chest revealed the large mediastinal mass completely surrounding and eroding into the superior vena cava (SVC wall causing a collar of stokes. The cardiac and SVC infiltration created a significant therapeutic challenge as lymphomas are very responsive to chemotherapy, and treatment could potentially lead to vascular wall rupture and hemorrhage. Despite the lack of conclusive data on chemotherapy-induced hemodynamic compromise in such scenarios, her progressive severe SVC syndrome and respiratory distress necessitated urgent intervention. In addition to the unique presentation of this rare lymphoma, our case report highlights the safety of R-CHOP treatment.

  7. Implementation and importance of fluorescence in situ hybridization (fish) in paraffin tissues for categorization of B-cell lymphoma unclassifiable, with features intermediate between Burkitt lymphoma and diffuse large B-cell lymphoma

    International Nuclear Information System (INIS)

    The diagnostic criteria have been defined based on the tools that the country has acquired and international guidelines for pure entities: the LB, LDCGB, and the new entity of B lymphoma unclassifiable with features intermediate LDCGB and LB. The fluorescence in situ hybridization for the translocation (8;14) has been implemented in paraffin tissues for proper categorization. A total of 21 cases have been studied: the characteristics of patients, morphology, immunohistochemistry and the presence or absence of the translocation (8;14). Twelve of the cases have been classified as B-cell lymphoma unclassifiable with features intermediate between LDCGB and LB. Furthermore, nine of the cases were classified in LB. Fluorescence in situ hybridization (FISH) has been negative in 5 of the 21 cases. The diagnosis of lymphoma with features bordering between the LB and the LDCGB has been imperative for the survival of the patient and the corresponding treatment

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

    The outcome of patients with follicular lymphoma (FL) has improved over the last two decades through the introduction of anti-CD20 monoclonal antibodies, usually used in combination with chemotherapy. However, patients with FL still experience multiple relapses, requiring several lines of treatment. Early toxicity of chemotherapy is a significant concern and as the life expectancy of patients with FL is increasing, late toxicities become an increasingly important concern. Progress made in understanding the biology of FL, especially dysregulation of intracellular pathways and immunological antitumor responses, recently allowed for the development of innovative chemo-free therapeutic approaches. In this report, different options such as new anti-CD20 antibodies, antibodies targeting other cell surface antigens, bi-specific antibodies, immunomodulation, idiotype vaccine and other targeted therapies are presented. The article also highlights how, although promising in early phase studies, the cost-effectiveness of new agents will have to be justified in Phase III trials. Furthermore, chemo-free regimen might not mean toxicity-free treatment and monitoring of early and late toxicities is required. PMID:25585961

    We describe a patient with persisting fevers, a progressive pulmonary infiltrate, and high levels of serum lactate dehydrogenase. No underlying cause for these changes was found prior to her death despite extensive investigations. Postmortem tissue revealed invasive pulmonary aspergillosis and subsequent brain examination revealed vascular changes in keeping with intravascular large B-cell lymphoma (IVLBCL). On review, subtle yet extensive lymphomatous infiltrates involved the vasculature of multiple other organs, including the lungs. Aspergillosis is a relatively rare presenting feature of lymphoproliferative disorders, and IVLBCL is a rare subtype of diffuse large B-cell non-Hodgkin's lymphoma with, to our knowledge, very few case reports to date. Lymphoma should be considered in patients presenting with pneumonitis with bilateral lung infiltrates on imaging, with a high serum level of lactate dehydrogenase. PMID:25473570

    Anaplastic lymphoma kinase (ALK)-positive diffuse large B-cell lymphoma (DLBCL) is a rare and distinct variant of DLBCL. It is classified as a unique subtype of DLBCL in the 2008 WHO classification of lymphomas. No standard and effective therapeutic regi-men is available for ALK+DLBCL because it shows a more aggressive clinical course and frequent relapse. Therefore, a standardized and individualized treatment is needed to benefit more patients diagnosed with ALK+DLBCL through a multiple disciplinary team. This arti-cle presents a case of an ALK+DLBCL patient who relapsed after transplantation and was successfully treated with the ALK kinase inhibi-tor Crizotinib.%ALK+弥漫大B细胞淋巴瘤(anaplastic lymphoma kinase-positive diffuse large B-cell lymphoma,ALK+DLBCL)是淋巴瘤中一种罕见的和具有明显差异性的病理类型,2008年WHO将其归类为DLBCL一个独特的亚型,该病侵袭性高,容易复发,目前尚无规范有效的治疗方案。采取多学科协作体系(multidisciplinary treatment,MDT)有利于制定规范化、个体化的治疗方案,探索针对ALK+DLBCL患者更有效的治疗方法,从而让更多的患者获益。本研究分享1例2012年1月天津医科大学肿瘤医院收治的ALK+DLBCL高剂量化疗联合自体造血干细胞移植(autologous hematopoietic stem cell transplantation,AHSCT)后复发,采用ALK激酶抑制剂克唑替尼(Crizotinib)治疗成功的案例。

  14. A teleradiotherapeutic network for lymphoma patients within the competence network malignant lymphomas

    International Nuclear Information System (INIS)

    Purpose: The aim of the subproject ''Radiotherapy'' within the competence network malignant lymphoma, funded by the Federal German Ministry of Education and Research (BMBF), was to build-up an electronic imaging transfer between five University departments of Radiation Oncology to improve communication between study centers and reference centers. Materials and Methods: We describe our experiences with these modern teleradiotherapeutic possibilities, its feasibility within multicentric clinical trials. Results: Telemedical functions could successfully be integrated into the existing quality assurance programs of radiotherapy. Since January 2001 more than 700 patients (trials HD10-HD15 of the German Hodgkin Study Group, GHSG) could be assessed after digital transfer via internet, on mobile data carriers or an ISDN-connection in the radiotherapy reference center Cologne. Transfer of digital imaging between participating study centers and the radiotherapy reference center allows immediate or a short-term evaluation of adequacy of treatment fields by expert radiation oncologists before the start of radiotherapy. This improves dialogue and consensus between radiotherapy reference centers and study centers and thus contributes towards high radiotherapy quality for lymphoma patients. Conclusion: The long-term aim is to network all those hospitals, institutions and private facilities taking part in the GHSG trials to achieve an integrated system of cooperation. This improves dialogue and consensus between the radiotherapy reference center and the study centers and thus contributes towards high radiotherapy quality for patients with Hodgkin's lymphoma.

    Full Text Available Hepatitis virus infections can lead to more critical outcomes such as severe hepatic dysfunction, failure and fulminancy in immunosuppressive patients compared to immunocompetent individuals. It is globally accepted that reactivation of both Hepatitis B virus [HBV ] and Hepatitis C virus [HCV] occurs after chemotherapy and antibody treatments of malignant diseases or solid organ/ bone marrow transplant in recipient patients. Especially among B-cell Non Hodgkin Lymphoma [NHL] patients, according to various studies, the seroprevelance of HCV is higher than that of the general population. On the other hand the role of HCV in the pathogenesis and etiology of NHL has been suggested. Today, cytotoxic drugs, corticosteroids, rituximab and hepatotoxic regimens are administered to NHL patients. Specifically, it has been emphasized that the utilization of rituximab [Anti CD20 antibody ] regiments for B-cell NHL patients may result with flares in HCV patients conspicuously. Here, we report the case of an acute flare up due to HCV infection in a patient who underwent a 4 month course of rituximab containing chemotherapy against a B cell NHL [CD20+ ] disease and a dramatic recovery from HCV infection at the end.

  16. Cerebral toxoplasmosis and lymphoma in patients with Acquired Immunodeficiency Syndrome

    International Nuclear Information System (INIS)

    Toxoplasmosis now constitutes a relatively frequent central nervous system (CNS) complication of AIDS, primary CNS lymphoma being far less common. CT scanning using the double-dose delayed (D-D-D) scan technique has proved an effective way of helping in the diagnosis of these complications. 16 patients with CNS complications of the acquired immunodeficiency syndrome (AIDS) are described. All patients were male homosexuals. The most common demonstrable lesion in the parenchyma was toxoplasmosis, which produced an area of focal oedema, usually containing a central zone of nodular or ring-shaped enhancement. Cerebral atrophy was also a common finding. One patient had diffuse peri-ventricular lymphomatous infiltration, and a further two patients had both cerebral toxoplasmosis and lymphoma. A delayed double dose contrast examination appears to be the most accurate method of outlining the total extent of CNS disease in these patients. 11 refs., 7 figs., 2 tabs

    2015-10-01

    Retinoids are natural and synthetic vitamin A analogs with effects on cell proliferation, differentiation, and apoptosis. They have significant activity in hematologic malignancies and have been studied extensively in cutaneous T-cell lymphoma. Retinoids bind to nuclear receptors and exert their effects through moderation of gene expression. Retinoic acid receptor and retinoic X receptor exert regulatory activity in vivo, binding to distinct ligands. Studies investigating systemic retinoids as monotherapy and in combination with other agents active against cutaneous lymphoma are reviewed. Side effects associated with retinoids include teratogenicity, dyslipidemias, and hypothyroidism, which should be carefully monitored in patients receiving treatment. PMID:26433844

    Bexarotene, a synthetic retinoid licensed for the treatment of refractory cutaneous T-cell lymphoma (CTCL), has been used clinically in Poland since 2007 in 21 patients. The objective of our retrospective, multicenter study was to evaluate our experience with bexarotene therapy, including efficacy, safety, and survival outcomes. We retrospectively identified 21 adult patients who were treated with bexarotene between the years 2007 and 2012. Starting dose of bexarotene was 300 mg/m per day. The analysis included 3 patients with early-stage mycosis fungoides (MF), 16 patients with advanced-stage MF, and 2 patients with Sézary syndrome (SS). The mean duration of therapy with bexarotene was 14.5 months. Use of bexarotene resulted in an overall response rate of 81.0%, although the overall mortality rate was 52.8%. In our study, early-stage CTCL responded better than advanced-stage CTCL (100.0% vs. 77.8%, respectively). The mean time to observable response was 1.8 months, and the mean duration of the response was 16.4 months. Most significant side effects were hyperlipidemia, hypothyroidism, and a bleeding gastric ulcer. Based on the results of our analysis, bexarotene is a valuable tool in the treatment of refractory early-stage CTCL. Although a majority of patients initially responded to therapy, the high mortality rate in the advanced-stage group suggests that bexarotene does not completely resolve the therapeutic problems in all stages of CTCL. Patient stratification for bexarotene treatment may need a thorough reassessment, in that bexarotene may not be an effective drug in the very advanced stages of CTCL. PMID:24732904

  1. Skeletal manifestation of Non-Hodgkin's lymphoma in pediatric patients

    International Nuclear Information System (INIS)

    Purpose. Skeletal manifestation of Non-Hodgkin's lymphoma is rare in pediatric patients. Objective of the study was to determine imaging features, before and after treatment, and to correlate these features with clinical outcome. Methods. A retrospective analysis of 1246 patients from two therapy studies (NHL-BMF-90 and 95) was performed. Imaging studies of 63 patients with bone involvement of lymphoma were reevaluated. Results. Incidence of initial bone involvement in Non-Hodgkin's lymphoma was 6.8%. Distribution was best assessed by bone scan, MRI revealed larger areas of marrow involvement and detected additional lesions. Sites of prediliction were long bones of the lower extremities with epiphyseal involvement in 39%. Residual signal alterations in MRI after successful therapy remained in 71%. Osteonecrosis after therapy was a common finding. Clinical outcome war not correlated to the presence of bone involvement. Conclusions. Since clinical outcome is not effected by bone involvement in childhood NHL, value of screening may be limited. Knowledge of imaging characteristics is mandatory for initial evaluation of primary osseous lymphomas and symptomatic lesions as well as for therapy controlls. (orig.)

    The purpose of this study was to reveal the diagnostic accuracy of initial pathologic assessment of biopsied samples in patients with gastrointestinal follicular lymphoma lesions. A total of 48 patients with follicular lymphoma (Lugano system stage I: n = 30; II1: n = 4; II2: n = 4; IV: n = 10) with gastrointestinal involvement who underwent endoscopic biopsy were enrolled and retrospectively reviewed. Nine (18.8%) of the 48 patients were not appropriately diagnosed as having follicular lymphoma at the initial biopsy. The initial pathological diagnosis included extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (n = 4), necrotic tissue (n = 2), duodenitis (n = 1), or suspected lymphoma of unspecified subtype (n = 2). The reasons for these inappropriate diagnoses were insufficient histopathologic analysis lacking CD10 and BCL2 staining (n = 7) and unsuitable biopsy samples taken from erosions or ulcers that contained scanty lymphoma cells or no lymphoid follicles (n = 2). In conclusion, incomplete histopathologic analysis and unsuitable biopsy samples are pitfalls in the diagnosis of gastrointestinal follicular lymphoma. PMID:24513028

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

    Full Text Available Non-Hodgkin’s Lymphoma (NHL rarely presents during pregnancy and primary mediastinal large B-cell lymphoma (PMLBCL accounts for approximately 2.5% of patients with NHL. The case of a 22-year-old woman who was diagnosed with Stage IIA PMLBCL during week 13 of her intrauterine pregnancy is described. The staging consisted in computed tomography (CT of the chest and magnetic resonance imaging (MRI of the abdomen and pelvis. She was managed with R-CHOP regimen (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone for a total of six cycles and, because of the early presentation during the second trimester, she received the entire chemotherapy course during the pregnancy. She delivered a healthy baby at 34 weeks of pregnancy and a 18FDG-PET/CT scan demonstrated complete remission after delivery. After 20 months of follow up she remains with no evidence of disease and her 1-year-old son has shown no developmental delays or physical abnormalities. PMLBCL, although an uncommon subgroup of DLBCL, may present during pregnancy and R-CHOP should be considered as one suitable option in this complex scenario.

    Follicular lymphoma (FL) is the prototypical model of indolent B cell lymphoma displaying a strong dependence on a specialized cell microenvironment mimicking normal germinal center. Within malignant cell niches in invaded lymph nodes and bone marrow, external stimuli provided by infiltrating stromal cells make a pivotal contribution to disease development, progression, and drug resistance. The crosstalk between FL B cells and stromal cells is bidirectional, causing activation of both partners. In agreement, FL stromal cells exhibit specific phenotypic, transcriptomic, and functional properties. This review highlights the critical pathways involved in the direct tumor-promoting activity of stromal cells but also their role in the organization of FL cell niche through the recruitment of accessory immune cells and their polarization to a B cell supportive phenotype. Finally, deciphering the interplay between stromal cells and FL cells provides potential new therapeutic targets with the aim to mobilize malignant cells outside their protective microenvironment and increase their sensitivity to conventional treatment.

    Bendamustine is approved in the United States for relapsed indolent lymphoma. However, it has not been widely studied in mantle cell lymphoma (MCL). We retrospectively reviewed the records of all patients with MCL who were treated with bendamustine at three centers. The primary endpoint was overall response rate (ORR). Thirty patients with MCL received bendamustine, 25 for relapsed disease. After a median follow-up of 12 months, there were 15 complete responses (CRs) with an ORR of 83% (95% c...

    Full Text Available Objective: Non-Hodgkin’s lymphoma (NHL of bone is a rare entity. The most common histological subtype is diffuse large B cell lymphoma (DLBCL. The major presenting symptoms are soft tissue swelling, bone pain and pathological fracture. Treatment options are chemotherapy, radiotherapy, surgery, or a combination of these modalities. Materials and Methods: We retrospectively analyzed the 18 patients (11 females, 7 males with NHL of bone who were diagnosed and treated between 1995-2005. The median age was 56.5 years. The median duration of symptoms was 4.5 months. The bone pain was the first symptom in all patients. Tru-cut biopsy was performed for diagnosis in most of the cases. Diagnosis in five patients (27.8% required open biopsy. Results: DLBCL (77.8% was the most common histological type among all patients. Other histological subtypes were anaplastic large cell lymphoma (11.1%, Burkitt-like lymphoma (5.6% and marginal zone lymphoma (5.6%. According to Ann Arbor staging system, 44.4% of patients were Stage I, 11.1% were Stage II and 44.4% were Stage IV. Bone marrow involvement was determined in four patients (22.2%. All patients except one were treated with anthracycline-containing regimens and eight patients (44.4% received rituximab combination with chemotherapy. Radiation therapy was performed as the first-line therapy in 9 (50% patients. The median follow-up was 37 months (range, 2-124 months. Among the 17 patients who achieved complete remission, five (27.8% relapsed. All patients were still alive. The five-year relapse-free survival was 73.5%.Conclusion: The treatment of bone lymphoma can be planned according to the stage and location of the disease. Although we had a relatively low number of patients, it could be concluded that whether or not radiation therapy is performed, rituximab in combination with systemic chemotherapy has been proven beneficial on survival.

  11. Positron Emission Tomography/Computed Tomography Findings During Therapy Predict Outcome in Patients With Diffuse Large B-Cell Lymphoma Treated With Chemotherapy Alone but Not in Those Who Receive Consolidation Radiation

    International Nuclear Information System (INIS)

    Purpose: To assess the value of mid-therapy positron emission tomography (PET) findings for predicting survival and disease progression in patients with diffuse large B-cell lymphoma, considering type of therapy (chemotherapy with or without radiation therapy). Methods and Materials: We retrospectively evaluated 294 patients with histologically confirmed diffuse large B-cell lymphoma with respect to age, sex, disease stage, International Prognostic Index score, mid-therapy PET findings (positive or negative), and disease status after therapy and at last follow-up. Overall survival (OS) and progression-free survival (PFS) were compared according to mid-therapy PET findings. Results: Of the 294 patients, 163 (55%) were male, 144 (49%) were age >61 years, 110 (37%) had stage I or II disease, 219 (74%) had International Prognostic Index score ≤2, 216 (73%) received ≥6 cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, and 88 (30%) received consolidation radiation therapy. Five-year PFS and OS rates were associated with mid-therapy PET status: PFS was 78% for those with PET-negative (PET−) disease versus 63% for PET-positive (PET+) disease (P=.024), and OS was 82% for PET− versus 62% for PET+ (P<.002). These associations held true for patients who received chemotherapy only (PFS 71% for PET− vs 52% PET+ [P=.012], OS 78% for PET− and 51% for PET+ [P=.0055]) but not for those who received consolidation radiation therapy (PFS 84% PET− vs 81% PET+ [P=.88]; OS 90% PET− vs 81% PET+ [P=.39]). Conclusion: Mid-therapy PET can predict patient outcome, but the use of consolidation radiation therapy may negate the significance of mid-therapy findings

    Full Text Available Cystic odontoma is a rare entity, which is characterized by the association of a cyst with complex/compound odontoma. The aim of this study was to report the case of a 5-year-old male patient diagnosed previously with Hodgkin’s lymphoma and treated successfully with chemotherapy and radiotherapy, who developed a mandibular odontogenic lesion. Physical examination revealed a swelling on the right side of the mandible. Radiographically, a well-defined radiolucent area surrounded by radiopaque material was observed. An incisional biopsy was performed and microscopic analysis showed a cystic lesion consisting of an atrophic epithelium comprising 2-3 cell layers and the absence of inflammation in the cystic capsule. The cyst was decompressed and the lesion was removed after 3 months of follow-up. Microscopic analysis of the surgical specimen showed a cystic hyperplastic epithelium surrounded by an intense chronic inflammatory cell infiltrate, which was in close contact with mineralized tissue resembling dentin and cementum. The final diagnosis was cystic odontoma. Since chemotherapy can affect the growth and development of infant teeth, a relationship between chemotherapy-associated adverse events and cystic odontoma is suggested in the present case.

    2015-01-01

    Rituximab is a monoclonal antibody against CD20. Rituximab combined with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy, termed R-CHOP, have improved the overall survival of patients with B-cell lymphoma in comparison with that of CHOP therapy. However, as with other molecularly-targeted therapies, resistance to rituximab could emerge sooner or later after rituximab administration. A number of mechanisms for rituximab resistance have been proposed, including downregulation of CD20 protein expression. Differential diagnosis of B-cell proliferation with reduced or lost CD20 expression includes not only B-cell lymphomas with CD20 downregulation, but also other tumorous and non-tumorous lesions. These include precursor B-cell neoplasms such as B acute lymphoblastic leukemia/lymphoblastic lymphoma (B-ALL/LBL) and hematogones, a normal precursor B-cell proliferation during regeneration of hematopoiesis, typically observed following bone marrow suppression by chemotherapy. It is important to distinguish these possibilities because distinct therapies are required for each. In this paper, we report a case where bone marrow infiltration of follicular lymphoma histopathologically mimicked hematogones or B-ALL/LBL when CD20 expression was downregulated in follicular lymphoma after R-CHOP therapy.

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

    Full Text Available Bansari Patel, Brooke V Rossi Division of Reproductive Endocrinology and Infertility, Department of Obstetrics and Gynecology, Case Western Reserve University, Cleveland, OH, USA Abstract: Fertility preservation affords patients the ability to reproduce after the initial diagnosis and management of such malignancies as Hodgkin's and non-Hodgkin's lymphoma. Certain chemotherapy regimens and pelvic radiotherapy confer a high-risk of subsequent gonadal compromise in both males and females. Fortunately, early counseling and initiation of fertility-preservation strategies promptly after diagnosis enable patients to maintain hope for future reproduction. Well-established methods for fertility preservation include embryo and oocyte cryopreservation in females and sperm cryopreservation in males. These methods enable patients to utilize assisted reproductive technologies, including in vitro fertilization, at the time of desired childbearing in order to ensure genetic offspring. As most of these modalities are not feasible in some patient populations, including prepubescent patients, newer methods of fertility preservation must be created to ensure the ability to produce genetic offspring in lymphoma patients. This review provides insights into the impact of gonadotoxic treatment on ovarian and testicular function, and highlights current modalities in fertility preservation in both males and females.

    Anaplastic large-cell lymphoma (ALCL) is a CD30-positive T-cell/null-cell lymphoma that is clinically classified into either primary cutaneous ALCL or systemic ALCL (S-ALCL) sub-types. Because 90% of childhood S-ALCL cases are anaplastic lymphoma kinase (ALK)-positive, there is a lack of data on ALK-negative S-ALCL cases among pediatric patients. Herein, we report a rare case of ALK-negative S-ALCL in a 9-year-old Korean boy who initially presented with itchy erythematous maculopapules and an erosive nodule on the trunk area. We emphasize the need of high index of suspicion of an underlying malignant disease in the presence of refractory eczematous lesions. PMID:27274637

    Full Text Available Hepatosplenic T-cell lymphoma (HSTCL is a rare non-Hodgkin lymphoma, marked by liver, spleen, and bone marrow sinusoidal infiltration, with an aggressive clinical course, which represents a difficult diagnostic task for clinicians and pathologists. Another equally severe and challenging condition is the hemophagocytic lymphohistiocytosis (also called hemophagocytic syndrome [HS], which is often associated with hematologic malignancies and infectious diseases. The authors report the case of a 56-year-old woman diagnosed with HSTCL based on bone marrow aspirate flow cytometry and skin biopsy. The patient underwent a cycle of chemotherapy but the outcome was unfavorable with multiple organ failure. The laboratory analysis was consistent with HS. The autopsy confirmed both the remaining lymphoma in the pulmonary vessels and the hemophagocytic cells in the spleen and bone marrow.

    Haematogones are normal, maturing B-cell precursors. They can be confused with neoplastic immature lymphoid cells of B lymphoblastic leukaemia/lymphoma or B-cell acute lymphoblastic leukaemia (B-ALL). Though multi-colour flow-cytometry strategies for distinguishing haematogones from cells of B-ALL are well-described, similar strategies have not been determined for bone marrow trephine biopsies (BMTB). We revisited the morphological and immunohistochemical features (CD20, CD34, TdT and PAX5 expression) in 69 BMTB from 62 patients - 27 with excess haematogones; seven with residual B-ALL after therapy; 18 with no reported excess of haematogones or residual acute leukaemia on BMTB; and 17 diagnostic samples of B-ALL. The distinctive immunophenotypic pattern of BMTB with excess haematogones was of CD34, TdT, CD20 and PAX5 accounting for increasing proportions of cells in the order mentioned, whereas among B-ALL, the immunohistochemical pattern was of CD20, PAX5 and TdT accounting for an equal proportion of cells. Furthermore, among haematogones, the intensity of CD20 expression was extremely heterogeneous as compared to the neoplastic cells in CD20-positive B-ALL. The TdT-positive haematogones were generally small and uniform, while a certain degree of heterogeneity was noticed among neoplastic B-ALL cells. This study provides a practical strategy to distinguish haematogones from B-ALL cells in BMTB. PMID:21722099

    The ATM protein senses DNA double-stranded breaks (DSBs) and facilitates proper repair. B and T lymphocytes of ATM-deficient patients have increased antigen receptor locus translocations associated with aberrant V(D)J recombination. Correspondingly, ATM-deficient humans are predisposed to both T and B cell malignancies. However, ATM-deficiency in mice only leads to T cell lymphomas, all of which harbor T cell receptor locus translocations resulting from aberrant V(D)J recombination. The first...

    Background The World Health Organization and European Organization for Research and Treatment of Cancer (WHOEORTC) classification in 2005 promoted the comparisons of primary cutaneous lymphoma (PCL) subtypes between different countries.The relative frequency of PCL varied according to geography.The study aimed to analyze the relative frequency and survival of PCLs in China and to compare the data with the published results from other countries.Methods We analyzed 98 patients with PCLs over a 6-year period and reclassified them according to the most recent WHO-EORTC classification (2005).Disease-specific survival rate and curves according to specific subtypes such as mycosis fungoides,lymphomatoid papulosis,and primary cutaneous peripheral T-cell lymphoma,unspecified was also calculated.Results The relative rate of PCL in China was distinct from those in Western countries.Our study showed a higher frequency of cutaneous T-and NK-cell lymphomas (CTCLs) (94%),and a lower frequency of cutaneous B-cell lymphomas (CBCLs) (6%).The 5-year survival rate of the total PCLs was 82%.There was no significant difference in the 5-year survival rate (P >0.05 by Log-rank test) between CTCL (80%) and CBCL (100%).Conclusions The higher percentage of CTCL in China may provide a clue to further study the etiological factors of PCLs.Racial variations in factors such as HLA determinants may play a role in the development of CTCL.

ATP-competitive "active-site" mTOR inhibitors produce more complete mTOR inhibition and are more effective than rapamycin in preclinical models of leukemia, lymphoma and multiple myeloma. In parallel to clinical trials of active-site mTOR inhibitors, it will be important to identify resistance mechanisms that might limit drug efficacy in certain patients. From a panel of diffuse large B-cell lymphoma cell lines, we found that the VAL cell line is particularly resistant to apoptosis in the presence of active-site mTOR inhibitors. Mechanistic investigation showed that VAL does not express eukaryotic initiation factor 4E-binding protein-1 (4EBP1, a key negative regulator of translation controlled by mTOR. Although VAL cells express the related protein 4EBP2, mTOR inhibitor treatment fails to displace eukaryotic initiation factor 4G from the mRNA cap-binding complex. Knockdown of eukaryotic initiation factor 4E, or re-expression of 4EBP1, sensitizes cells to apoptosis when treated with active-site mTOR inhibitors. These findings provide a naturally occurring example of 4EBP deficiency driving lymphoma cell resistance to active-site mTOR inhibitors.

    High-grade B-cell lymphomas (HGBCLs) are a heterogeneous group of neoplasms that include subsets of diffuse large B-cell lymphoma, Burkitt lymphoma, and lymphomas with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma. Morphologically indistinguishable HGBCLs may demonstrate variable clinical courses and responses to therapy. The morphologic evaluation and classification of these neoplasms must be followed by further genetic and immunophenotypic work-up. These additional diagnostic modalities lead to a comprehensive stratification of HGBCL that determines the prognosis and optimal therapy. This article reviews the well-established and emerging biomarkers that are most relevant to the clinical management of HGBCL. PMID:26940267

  15. Lymphoma-clinical questions

    International Nuclear Information System (INIS)

    Lymphoma is a group of neoplastic disease of lymphoid tissues, which can be classified into categories of Hodgkin's disease and non-Hodgkin's lymphoma(NHL). Prognosis of lymphoma depends on the extent of disease (staging) especially in Hodgkin's disease, but also depends on the histologic make up in non-Hodgkin's lymphoma. Although non-Hodgkin's lymphoma is a neoplastic transformation of lymphoid cell it is a collection of disease with morphologically and immunologically diverse make up. Consequently the classification of NHL has changed frequently and evolved according to the progress of immunologic and molecular knowledge added to the original morphologic classification. Lymphoma is a disorder sensitive to chemotherapy which often leads to cure of the disease even in advanced stage, while many other patients die from the progression of disease. Therefore, better understanding in newer classification and sensitive imaging technique, such as PET, in lymphoma will likely lead to the improvement of survival rate

    A non-healing peri-anal abscess can be difficult to manage and is often attributed to chronic disease. This case documents a male in his seventh decade who presented with multiple peri-anal collections. The abscess cavity had caused necrosis of the internal sphincter muscles resulting in faecal incontinence. Biopsies were conclusive for diffuse large B-cell lymphoma. A de-functioning colostomy was performed and the patient was initiated on CHOP-R chemotherapy. Anal lymphoma masquerading as a peri-anal abscess is rare. A high degree of suspicion must be maintained for an anal abscess which does not resolve with conservative management. PMID:24898408
