mantel cell lymphoma relapsed

Intravascular lymphomatosis (IVL) is a rare and clinically devastating form of extranodal B-cell non-Hodgkin's lymphoma. We performed a comprehensive analysis of the literature on IVL's published between 1959 and 2011 and evaluated the natural history as well as identified prognostic and predictive factors in patients. Nonparametric two-tailed Mann-Whitney U-test and Mantel-Cox log rank test were used to evaluate the survival intervals and prognostic factors. Multivariate analysis of variance (MANOVA) and chi-squared statistics were carried out to examine treatment-related predictive factors...

The stratification of patients with acute lymphoblastic leukemia (ALL) into treatment risk groups based on quantification of minimal residual disease (MRD) after induction therapy is now well accepted but the relapse rate of about 20% in intermediate risk patients remains a challenge. The purpose of this study was to further improve stratification by MRD measurement at an earlier stage. MRD was measured in stored day 15 bone marrow samples for pediatric patients enrolled on ANZCHOG ALL8 using Real-time Quantitative PCR to detect immunoglobulin and T-cell receptor gene rearrangements with the same assays used at day 33 and day 79 in the original MRD stratification...

BACKGROUND: Addition of the anti-CD20 monoclonal antibody rituximab to chemotherapy (R-chemo) has been shown to improve response rates and progression-free survival in patients with indolent or mantle cell lymphoma. However, the impact of R-chemo on overall survival is unclear. We performed a comprehensive systematic review and meta-analysis to examine the efficacy of combined immunochemotherapy using R-chemo compared with the identical chemotherapy alone with respect to overall survival in patients with advanced indolent lymphoma or mantle cell lymphoma...

PURPOSE: The role of hematopoietic stem-cell transplantation (SCT) in first complete remission (CR1) for children with very high-risk (VHR) acute lymphoblastic leukemia (ALL) is still under critical discussion. PATIENTS AND METHODS: In the ALL-Berlin-Frankfurt-Münster (BFM) 90 and ALL-BFM 95 trials, 387 patients were eligible for SCT if there was a matched sibling donor (MSD). T-cell ALL (T-ALL) patients with poor in vivo response to initial treatment represented the largest homogeneous subgroup within VHR patients...

Fourteen patients with high-risk T-lineage acute lymphoblastic leukemia (ALL) in complete remission underwent autologous bone marrow transplantation (BMT) in an attempt to eradicate their residual disease burden. A combined immunochemotherapy protocol using a cocktail of two immunotoxins directed against CD5/Tp67 and CD7/Tp41 T-lineage differentiation antigens in combination with the in vitro active cyclophosphamide congener 4-hydroperoxy-cyclophosphamide (4-HC) was used to purge autografts. Despite high dose pretransplant radiochemotherapy and effective purging of autografts, 9 of 14 patients relapsed at a median of 2...

Adhesive interactions between lymphocyte cell-surface receptors and components of the vascular endothelium and the extracellular matrix play an important role in the control of lymphocyte migration and homing. To investigate whether lymphocyte adhesion molecules involved in the migration of normal lymphocytes, i.e., CD44 homing receptor, LFA-1 (CD11a/18), and ICAM-1 (CD54), also play a role in the spread and hence in the disease course of non-Hodgkin's lymphomas (NHL), expression of these molecules was examined in 78 cases of diffuse large-cell lymphoma...
