Central nervous system involvement in diffuse large B-cell lymphoma

EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 1 2010
Wataru Yamamoto
Abstract Background:,Malignant lymphoma with central nervous system (CNS) involvement has an extremely poor prognosis. We retrospectively studied the risk factors for CNS involvement in patients with diffuse large B-cell lymphoma (DLBCL) treated by cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or rituximab (R) -CHOP chemotherapy. Patients and methods:,We studied 375 consecutive patients who were newly diagnosed with DLBCL between 1996 and 2006. Patients with primary CNS involvement and patients who received CNS prophylaxis were excluded. All the patients received CHOP (n = 172) or R-CHOP (n = 203) chemotherapy. The following variables were assessed for their potential to predict CNS involvement: gender, age, serum lactate dehydrogenase (LDH) level, performance status, clinical stage, number of extranodal involvements, International Prognostic Index (IPI), bone marrow involvement, presence of a bulky mass, presence of B symptom, and treatment. Results:,CNS involvement was observed in 13 cases (3.5%). In univariate analysis, LDH more than normal range, LDH more than twice as normal range, high IPI, bone marrow involvement, and systemic relapse were the predictors for CNS involvement. In multivariate analysis, no risk factors were detected for CNS involvement. The use of rituximab did not have an impact on CNS involvement. Conclusions:,The incidence of CNS involvement dose not decrease in rituximab-era. [source]


Prognostic factors for classifying extranodal NK/T cell lymphoma, nasal type, as lymphoid neoplasia

EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 1 2007
Im I. Na
Abstract This study evaluated the applicability of prognostic factors commonly used for diagnosis of classical lymphoma outcomes to extranodal NK/T cell lymphoma, nasal type (NTCL). Clinical features and their associations with lactate dehydrogenase (LDH) were evaluated in 70 patients. RLDH was defined as the ratio of LDH to the upper normal limit. RLDH was associated with stage (I,II vs. III,IV), lymph node involvement (LNI), and International Prognostic Index score (<2 vs. ,2). Poor performance status and advanced stage were common in patients with local tumor invasiveness (LTI). LDH level, classified into three levels (low, high, and very high) was associated with survival (P < 0.001). In multivariate analysis, the predictive values of LDH level, B symptom, performance status, and stage remained significant whereas those of LTI and LNI did not. Scoring was performed by weighting each factor with 0.5 or 1.0 according to its hazard ratio. Scores were classified into four groups. Groups with high scores were associated with unfavorable outcomes (P < 0.001). Current study suggests that prognostic factors for NHL may be useful to predict the outcome of NTCL but the model should take LDH level and the prognostic weight of each factor into account.

Abstract Background. The purpose of this study was to investigate the clinical relevance of subtypes categorized by immunophenotypic analysis in primary sinonasal lymphomas. Methods. Eighty patients with localized non-Hodgkin's lymphoma involving the nasal cavity and/or paranasal sinuses were divided into three subtypes on the basis of their immunohistochemical findings: (A) B-cell lymphoma (n = 19), (B) T-cell lymphoma (n = 27), and (C) natural killer (NK)/T-cell lymphoma (n = 34). The clinicopathologic profiles, immunophenotypic data, patterns of treatment failure, and survival data among the three patient groups were retrospectively compared. Results. The nasal cavity was the predominant site of involvement in T-cell and NK/T-cell lymphoma, whereas sinus involvement without nasal disease was common in B-cell lymphoma. Systemic B symptoms were frequently observed in NK/T-cell lymphoma. Almost all patients with NK/T-cell lymphoma showed a strong association with the Epstein-Barr virus by in situ hybridization studies. Sixty-five patients (81%) patients achieved complete remission after initial treatment, but 36 (55%) of these subsequently experienced treatment failure. Although there were no significant differences in locoregional failure rates among the patients of the three groups, distant failure was far more common in B-cell or NK/T-cell lymphoma than in T-cell lymphoma (p = .005). Most B-cell lymphoma cases showed a predilection for sites of systemic failure in the nodal and extranodal sites below the diaphragm, such as the paraaortic lymph nodes or the gastrointestinal (GI) tract, whereas patients with NK/T-cell lymphoma showed an increased risk of systemic dissemination to the skin, testes, or GI tract, including the development of hemophagocytic syndrome. The 5-year actuarial and disease-free survival rates for all patients were 57% and 51%, respectively. Of the three subtypes of primary sinonasal lymphomas, T-cell lymphoma seemed to carry the most favorable prognosis and NK/T-cell lymphoma the worst. (The 5-year actuarial survival rate was 57% for B-cell lymphoma, 80% for T-cell lymphoma, 37% for NK/T-cell lymphoma; p = .02, log-rank.) By univariate and multivariate analyses, immunophenotype was identified as the most important prognostic factor. Conclusions. Our data indicate that the three subtypes of primary sinonasal lymphomas classified by immunohistochemical studies exhibit different clinical profiles, different patterns of failure, and different treatment outcomes. Given these observations, it is concluded that the recognition of these distinct subsets, diagnosed on the basis of immunophenotypic study, is very important and clinically relevant in predicting their potential behavior and prognosis. © 2004 Wiley Periodicals, Inc.

Prognostic significance of Fas (CD95/APO-1) positivity in patients with primary nodal diffuse large B-cell lymphoma

AMERICAN JOURNAL OF HEMATOLOGY, Issue 5 2006
Bulent Eser
Abstract Fas (CD95/APO-1) is a protein that is mainly related to apoptosis of lymphoid cells. The increment of Fas expression is associated with long-term survival in various malignancies. However, there are limited studies regarding the effect of Fas expression on the course and prognosis of non-Hodgkin's lymphoma. The aim of this study was to investigate the significance of immunohistochemical Fas expression on the prognosis of nodal diffuse large B-cell lymphoma. A total of 63 patients with primary nodal diffuse large B-cell lymphoma diagnosed in the Erciyes University Department of Hematology between 1990 and 2003 were included in the study. The median age of the patients was 55 years old (range 19,102 years old). The median follow-up period was 19 months (2,132 months). Histopathological sections were stained immunohistochemically and evaluated by light microscopy for Fas, bcl-2, and p53. Clinical and laboratory parameters including Fas, bcl-2, and p53 positivity, age, sex, performance status, clinical stage, presence of B symptoms, bone marrow involvement, extranodal involvement, and lactic dehydrogenase levels were evaluated to compare overall survival. Complete remission was obtained in 28 patients (44.4%) after first-line chemotherapy. Fas positivity, male gender, good performance status, clinical stage I-II, absence of B symptoms, normal lactic dehydrogenase value, and absence of bone marrow involvement were favorable prognostic factors for complete remission in statistical analysis. Multivariate analysis revealed that positive Fas expression and ECOG performance status were independent prognostic factors for overall survival. Also, Fas-positive patiens had significantly prolonged progression-free survival. Immunohistochemical Fas positivity was a favorable prognostic factor for complete remission and overall and progression-free survival in primary nodal diffuse large B-cell lymphoma. Am. J.

Epstein-Barr virus-related lymph node lesion resembling autoimmune disease-like clinicopathological findings in elderly patients Report of three cases

APMIS, Issue 12 2003
MASARU KOJIMA
Three cases of Epstein-Barr virus (EBV)-related lymphoproliferative disorders in elderly patients showing autoimmune disease-associated lymphadenopathy-like clinicopathological findings have been reported. Clinically, they were characterized by systemic lymphadenopathy, "B" symptoms, polyclonal hypergammaglobulinemia, elevated serum LDH and transient presence of various autoantibodies, and absence of atypical lymphocytosis in peripheral blood. One case was associated with idiopathic thrombocytopenic purpura. The clinical course was self-limiting. Histologically, they exhibited numerous lymphoid follicles with hyperplastic germinal centers and atypical interfollicular widening with prominent vascular proliferation. In the paracortical area, there was a mixed infiltrate comprising small to medium-sized lymphocytes and plasma cells, and variable numbers of eosinophils and T- and B-immunoblasts. In situ hybridization demonstrated a varying number of EBV-infected lymphocytes in the germinal center as well as in the interfollicular area. Polymerase chain reaction demonstrated that neither clonal rearrangement of T-cell receptor ,-gene nor immunoglobulin heavy-chain rearrangement was detected in two of the cases examined. Although acute EBV infection rarely occurs in older adults, EBV related to reactive lymphoproliferative disorder should be added to the differential diagnosis of autoimmune disease-associated lymphadenopathy and node-based peripheral T-cell lymphoma in elderly patients.

Acute viral lymphadenitis mimicking low-grade peripheral T-cell lymphoma A clinicopathological study of nine cases,

APMIS, Issue 6 2001

Acute viral lymphadenitis, especially infectious mononucleosis (IM), often shows the presence of Reed-Sternberg-like cells, resulting in confusion with Hodgkin's disease. However, acute viral lymphadenitis requiring differential diagnosis from non-Hodgkin's lymphoma is not widely recognized. We describe the clinicopathological and immunohistochemical features of lymph node lesions from nine such patients which pose serious problems of differential diagnosis from low-grade peripheral T-cell lymphoma. There were three males and six females with ages ranging from 21 to 44 years (median 25 years). All patients had "B" symptoms and multicentric lymphadenopathy. The clinical course was also self-limiting. Each lymph node specimen showed an obvious expansion of an interfollicular area by pleomorphic and polymorphous infiltration with an increased number of arborizing postcapillary venules. The infiltrate was composed of variable numbers of small and medium-sized lymphocytes, immunoblasts, plasma cells in various stage of maturation and occasional granulocytes. The small lymphocytes usually had regular round nuclei, whereas the medium-sized lymphocytes occasionally showed nuclear pleomorphism. Hyperreactivity of B-lymphocytes, including hyperplastic germinal centers and/or foci of monocytoid B-cells, was seen in parts of the lesion. The majority of the interfollicular T-lymphocytes, including T-immunoblasts, expressed CD8 antigen. Various numbers of TIA-1-positive small and medium-sized T-cells were observed in the paracortical area. Despite these findings, the overall histological picture of this series posed serious difficulties when differentially diagnosing this condition from low-grade peripheral T-cell lymphomas such as angioimmunoblastic T-cell (AILD) and T-zone types, indicating that viral lymphadenitis occasionally presents with histological features of AILD and T-zone lymphomas. To avoid overdiagnosis and overtreatment, we emphasize the need to pay careful attention to the clinical and laboratory findings as well as the morphological features. [source]


Prospective analysis of treatment outcome and prognostic factors in patients with T-cell lymphomas treated by CEOP-B: single institutional study

BRITISH JOURNAL OF HAEMATOLOGY, Issue 1 2006
Hwa Jung Sung
Summary The important prognostic factors were evaluated for T-cell non-Hodgkin lymphoma (NHL) patients in a prospective study using the CEOP-B protocol [a modified cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP)-like regimen that uses epirubicin instead of doxorubicin with the addition of bleomycin]. Fifty-two patients were enrolled in the study. The overall response rate was 63·5%. The median progression-free survival (PFS) and median overall survival (OS) was 18·0 and 39·5 months respectively. The most common toxicity was neutropenia. The factors related to poor outcome were a high International Prognostic Index (IPI) and a high ,B' score (bone marrow involvement, B symptoms, bulky disease). We developed a new prognostic model, namely the Prognostic Group for T cell NHL (PGT) that included four groups: PGT1 (low IPI/low B score), PGT2 (low IPI/high B score), PGT3 (high IPI/Low B score) and PGT4 (high IPI/Low B score). OS and PFS (not reached, 48 months) in the PGT1 group were significantly longer than those (11·5 and 4·8 months) in PGT2. The same result was observed in the PGT3 and PGT4 groups. The CEOP-B regimen was moderately active and tolerable for T-cell NHL patients, and the PGT system might be useful for the prediction of long-term survival of T-cell NHL patients. [source]


Diffuse large B-cell lymphoma

CANCER, Issue 21 2009
Clinical characterization, prognosis of Waldeyer ring versus lymph node presentation
Abstract BACKGROUND: The objective of this study was to compare the clinical features and prognosis of patients with diffuse large B-cell lymphoma (DLBCL) of Waldeyer ring (WR-DLBCL) and patients with lymph node DLBCL (N-DLBCL). METHODS: One hundred eighty-one patients with WR-DLBCL and N-DLBCL were reviewed. There were 57 patients with stage I disease, 83 patients with stage II disease, 26 patients with stage III disease, and 15 patients with stage IV disease. Among them, 101 patients had primary N-DLBCL, and 80 patients had primary WR-DLBCL. RESULTS: Patients with WR-DLBCL and N-DLBCL usually presented at an older age and had localized disease, a low frequency of B symptoms, a good performance status, and a low-risk International Prognostic Index (IPI) score. Compared with patients who had N-DLBCL, patients who had WR-DLBCL presented with more stage II disease and lower tumor burdens. The overall response rate after treatment was similar in both groups. The 5-year overall survival (OS) and progression-free survival (PFS) rates were 76% and 61% in patients with WR-DLBCL, respectively, and 56% and 50% in patients with N-DLBCL, respectively (P = .119 for OS; P = .052 for PFS). IPI scores and elevated ,2-microglobulin and LDH levels were associated with a poor prognosis for patients who had WR-DLBCL; whereas bulky tumor, elevated ,2-microglobulin levels, and IPI scores were associated with poor OS for patients who had N-DLBCL. CONCLUSIONS: The current results supported the continued inclusion of WR-DLBCL as a lymph node group in the staging of DLBCL. Patients with WR-DLBCL had clinical features and prognosis similar to those of patients with N-DLBCL. Cancer 2009. © 2009 American Cancer Society. [source]


Clinical implications of nodal marginal zone B-cell lymphoma among Japanese: study of 65 cases

CANCER SCIENCE, Issue 1 2007
Masaru Kojima
To clarify the clinical presentation and outcome of nodal marginal zone B-cell lymphoma (NMZBL), 65 Japanese patients with this disease were studied and compared with the published literature from western countries. The clinical findings of our 65 cases were similar to those of their cases in some aspects: (1) 58% of the patients were >60 years old (median age, 64 years); (2) there was a slight female predominance; (3) 90% of the patients exhibited asymptomatic lymphadenopathy in the head and neck area; (4) only a minority of patients had B symptoms (6%) and poor performance status (8%); and (5) only 5% of patients were positive for M-protein. However, the 65 patients in this series exhibited relatively longer 5-year overall survival (85%) and failure-free survival (60%) than the NMZBL series published in western literature, suggesting that NMZBL should be classified as indolent lymphoma. Moreover, based on the histological findings, we further classified four histological subtypes as follows: (1) splenic type (n = 7); (2) floral type (n = 9); (3) mucosa-associated lymphoid tissue (MALT) type (n = 29); and (4) diffuse large B-cell lymphoma (DLBCL) + MALT type (n = 20). DLBCL + MALT type exhibited significantly poorer 5-year overall survival than the splenic variant. The recognition of DLBCL + MALT type appears important. No API2,MALT1 fusion transcript was detected in any of the 14 cases examined. (Cancer Sci 2007; 98: 44,49) [source]
