Relapsed and/or Refractory Mantle Cell Lymphoma: What Role for Temsirolimus?

2012

Mantle Cell Lymphoma (MCL) is associated with a dismal prognosis. Recently, along with the improved understanding of the pathophysiology of this disease, new first line regimens have been established and in addition novel treatment options have entered the clinical arena. In consequence, prognosis of the disease has fortunately improved. We here focus on the rationale, current clinical knowledge and future concepts of Temsirolimus, an inhibitor of mTOR, in the treatment of MCL. At this time this drug has been shown to be effective as single agent for relapsed disease and early combination data show promising results. In addition, with a brief outline of other treatment options, we aim to g…

Results of a Phase II Study of Pixantrone in Combination with Cyclophosphamide, Vincristine, and Prednisone in Patients with Relapsed Aggressive Non-…

2006

Abstract Background: Pixantrone is a novel aza-anthracenedione with less cardiotoxicity and superior activity compared to doxorubicin and mitoxantrone in murine leukemia and lymphoma tumor models. Pixantrone as single agent therapy led to major responses in patients (pts) with multiply relapsed aggressive non-Hodgkin’s lymphoma (NHL), including diffuse large B-cell lymphoma (DLCL). In a phase I dose-ranging study of pixantrone (80 to 180 mg/m2) replacing doxorubicin (CPOP) in a CHOP-like regimen, the optimal dose (RD) from that study was found to be 150 mg/m2. Methods: In this international, multi-center, phase II study the primary objective was to assess the efficacy and safety of the CPOP…

Rationale and Design of the International Lymphoma Epidemiology Consortium (InterLymph) Non-Hodgkin Lymphoma Subtypes Project

2014

Background: Non-Hodgkin lymphoma (NHL), the most common hematologic malignancy, consists of numerous subtypes. The etiology of NHL is incompletely understood, and increasing evidence suggests that risk factors may vary by NHL subtype. However, small numbers of cases have made investigation of subtype-specific risks challenging. The International Lymphoma Epidemiology Consortium therefore undertook the NHL Subtypes Project, an international collaborative effort to investigate the etiologies of NHL subtypes. This article describes in detail the project rationale and design. Methods: We pooled individual-level data from 20 case-control studies (17 471 NHL cases, 23 096 controls) from North Ame…

Y-90 Ibritumomab Tiuxetan as Consolidation Following Three Cycles of Fludarabine-Cyclophosphamide-Rituximab Chemoimmunotherapy in Patients with Relap…

2007

Abstract BACKGROUND: Tumed sequential treatment with fludarabine/cyclophosphamide/rituximab (FC-R) followed by Y-90 ibritumomab tiuxetan (IT) radioimmunotherapy may improve progression-free survival in patients (pts) with CD20+ NHL. However, even unpretreated pts submitted to four to six cycles of a fludarabine-containing combination and then IT at an Y-90 activity of 15 MBq/kg will experience severe prolonged, transfusion-dependent and only partially reversible pancytopenia, thus limiting its use in a non-curative setting (Jurczak et al., ASH 2005). AIM: We report on a trial including anthracycline-pretreated pts with relapsing CD20+ lymphoma > age 50 and unsuitable for myeloablative tr…

Whole‐body magnetic resonance imaging (WB‐MRI) in lymphoma: State of the art

2019

The improvements in magnetic resonance imaging (MRI) technology and the concern related to the increased cancer risk in patients with lymphoma, also due to radiation exposure associated with imaging examinations, have led to the introduction of whole-body MRI (WB-MRI) as a radiation-free alternative to standard imaging procedures. WB-MRI seems a less histology-dependent functional imaging test than 18 F-fluorodeoxyglucose-positron emission tomography/CT (18 F-FDG-PET/CT). In patients with FDG-avid lymphomas, such as diffuse large B-cell lymphoma (DLBCL) and Hodgkin lymphoma (HL), 18 F-FDG-PET/CT remains the imaging reference standard for staging, with WB-MRI potentially being a complementar…

Initial chemotherapy with mitoxantrone, chlorambucil, prednisone impairs the collection of stem cells in patients with indolent lymphomas—results of …

2006

Myeloablative radio-chemotherapy with subsequent autologous stem cell transplantation (ASCT) significantly prolongs progression free and probably overall survival in follicular lymphoma (FL) in first remission. The current trial explored prospectively the rate of successful stem cell mobilization in patients with advanced stage FL after initial therapy with either Mitoxantrone, Chlorambucil, Prednisone (MCP) or Cyclophosphamide, Doxorubicin, Vincristine, Prednisone (CHOP) as part of a prospective randomized comparison of both regimens. ASCT patients received Dexa-BEAM (Dexamethasone, BCNU, Melphalan, Etoposide, Cytarabine) for mobilization of stem cells. Stem cells were collected and a mini…

Loss of a novel tumor suppressor gene locus at chromosome 8p is associated with leukemic mantle cell lymphoma

2001

Abstract Patients with mantle cell lymphoma (MCL) may present with either nodal or leukemic disease. The molecular determinants underlying this different biologic behavior are not known. This study compared the pattern of genetic abnormalities in patients with nodal and leukemic phases of MCL using comparative genomic hybridization (CGH) and fluorescence in situ hybridization (FISH) for specific gene loci. Although both leukemic and nodal MCL showed similar genomic patterns of losses (involving 6q, 11q22-q23, 13q14, and 17p13) and gains (affecting 3q and 8q), genomic loss of chromosome 8p occurred more frequently in patients with leukemic disease (79% versus 11%,P < .001). Subsequent…

Safety and efficacy of Temsirolimus in combination with Bendamustine and Rituximab in relapsed mantle cell and follicular lymphoma

2015

In this phase I/II study, we explored the combination of Temsirolimus with Bendamustine and Rituximab (BeRT) in patients with r/r follicular lymphoma (FL) or mantle cell lymphoma (MCL). Patients with 1-3 prior therapies received Bendamustine (90 mg/m(2), day 1+2) and Rituximab (375 mg/m(2), day 1) with Temsirolimus in doses from 25 to 75 mg added on day 1, 8, 15 of a 28-day cycle. Fifteen (11 MCL, 4 FL) patients were included in the phase I. Median age was 73 years and median pretreatment number was 2. No formal dose-limiting toxicity was observed. Dominant non-hematological side effects were fatigue in 11 (73%), nausea in 9 (60%), mucositis in 7 (47%) and vomiting in 6 patients (40%). Coug…

Evaluation of Safety, Tolerability and Efficacy of Temsirolimus in Patients with Relapsed or Refractory Mantle Cell Lymphoma (Rel/Refr Mcl) in Routin…

2014

ABSTRACT Aim: Temsirolimus (TEMS), an mTOR-inhibitor, is approved in the EU for the treatment of patients (pts) with relapsed or refractory (rel/refr) MCL. A pivotal study demonstrated significantly longer progression free survival with TEMS (175 mg weekly for 3 weeks followed by 75 mg weekly) in rel/refr MCL pts compared to investigatoŕs choice therapy (4.8 mo vs 1.9 mo; P = .0009). To evaluate safety and efficacy of TEMS in an unselected patient population during clinical routine, a prospective non-interventional study with TEMS in rel/refr MCL pts is useful. Here we report on interim results of the study. Methods: A German multicenter registry for rel/refr MCL pts treated with TEMS was s…
