Addition of high-dose cytarabine to immunochemotherapy before autologous stem-cell transplantation in patients aged 65 years or younger with mantle cell lymphoma (MCL Younger): a randomised, open-label, phase 3 trial of the European Mantle Cell Lymphoma Network.

Background: Mantle cell lymphoma is characterised by a poor long-term prognosis. The European Mantle Cell Lymphoma Network aimed to investigate whether the introduction of high-dose cytarabine to immunochemotherapy before autologous stem-cell transplantation (ASCT) improves outcome.

Methods: This randomised, open-label, parallel-group, phase 3 trial was done in 128 haemato-oncological hospital departments or private practices in Germany, France, Belgium, and Poland.

Single versus tandem high-dose melphalan followed by autologous blood stem cell transplantation in multiple myeloma: long-term results from the phase III GMMG-HD2 trial.

The prospective, randomized phase III trial GMMG-HD2 aimed at demonstrating non-inferiority of single (Arm A) versus tandem (Arm B) high-dose melphalan followed by autologous transplantation (HDM/ASCT) with regard to 2-year event-free survival (EFS) in newly-diagnosed multiple myeloma (MM) and included 358 evaluable patients [Intention-to-treat population, (ITT), single/tandem HDM/ASCT: n = 177/181]. After a median follow-up of more than 11 years, non-inferiority of single versus tandem HDM/ASCT was demonstrated using the planned non-inferiority threshold of 15% of the 2-year EFS rate. Neither EFS (P = 0·53) nor overall survival (OS) (P = 0·33) differences were observed in the ITT population.

Bortezomib before and after autologous stem cell transplantation overcomes the negative prognostic impact of renal impairment in newly diagnosed multiple myeloma: a subgroup analysis from the HOVON-65/GMMG-HD4 trial.

Renal impairment is frequent in patients with multiple myeloma and is correlated with an inferior prognosis. This analysis evaluates the prognostic role of renal impairment in patients with myeloma treated with bortezomib before and after autologous stem cell transplantation within a prospective randomized phase III trial. Eight hundred and twenty-seven newly diagnosed myeloma patients in the HOVON-65/GMMG-HD4 trial were randomized to receive three cycles of vincristine, adriamycin, dexamethasone (VAD) or bortezomib, adriamycin, dexamethasone (PAD) followed by autologous stem cell transplantation and maintenance with thalidomide 50 mg daily (VAD-arm) or bortezomib 1.

Conventional chemotherapy (CHOEP-14) with rituximab or high-dose chemotherapy (MegaCHOEP) with rituximab for young, high-risk patients with aggressive B-cell lymphoma: an open-label, randomised, phase 3 trial (DSHNHL 2002-1).

Background: High-dose therapy (HDT) followed by transplantation of autologous haemopoietic stem cells is frequently done as part of first-line therapy in young patients with high-risk aggressive B-cell lymphoma. We investigated whether HDT with cytotoxic agents identical to those used for conventional therapy followed by autologous stem-cell transplantation (ASCT) improved survival outcome compared with conventional chemotherapy when rituximab was added to both modalities.

Methods: We did an open-label, randomised trial comparing conventional chemotherapy (cyclophosphamide, doxorubicin, vincristine, etoposide, prednisone) and rituximab (R-CHOEP-14) with dose-escalated sequential HDT and rituximab (R-MegaCHOEP) followed by repetitive ASCT in high-risk (age-adjusted International Prognostic Index [IPI] 2 or 3) patients aged 18-60 years with aggressive B-cell lymphoma.

The role of sex and weight on rituximab clearance and serum elimination half-life in elderly patients with DLBCL.

Pharmacokinetics of 8 doses of rituximab (375 mg/m(2)) given in combination with 2-week cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisone/prednisolone (CHOP-14) was determined by ELISA in 20 elderly patients with diffuse large B-cell lymphoma (DLBCL) 10 minutes before and after each infusion and 1 week and 1, 2, 3, 6, and 9 months after the last infusion. Population pharmacokinetic modeling was performed with nonlinear mixed-effect modeling software (NONMEM VI). Concentration-time data were fitted into an open 2-compartment model and total clearance, central compartment volume, intercompartment clearance, and volume of distribution at steady-state (Vd(ss)) were investigated.

Administration of bortezomib before and after autologous stem cell transplantation improves outcome in multiple myeloma patients with deletion 17p.

In patients with multiple myeloma (MM), risk stratification by chromosomal abnormalities may enable a more rational selection of therapeutic approaches. In the present study, we analyzed the prognostic value of 12 chromosomal abnormalities in a series of 354 MM patients treated within the HOVON-65/GMMG-HD4 trial. Because of the 2-arm design of the study, we were able to analyze the effect of a bortezomib-based treatment before and after autologous stem cell transplantation (arm B) compared with standard treatment without bortezomib (arm A).

Treatment and prognosis of mature T-cell and NK-cell lymphoma: an analysis of patients with T-cell lymphoma treated in studies of the German High-Grade Non-Hodgkin Lymphoma Study Group.

To evaluate outcome and prognosis of patients with T-cell lymphoma we analyzed 343 patients treated within trials of the German High-Grade Non-Hodgkin Lymphoma Study Group (DSHNHL). Two hundred eighty-nine patients belonged to 1 of the 4 major T-cell lymphoma subtypes: anaplastic large cell lymphoma (ALCL), anaplastic large cell lymphoma kinase (ALK)-positive (n = 78); ALCL, ALK-negative (n = 113); peripheral T-cell lymphoma, unspecified (PTCLU; n = 70); and angioimmunoblastic T-cell lymphoma (AITL; n = 28). Treatment consisted of 6-8 courses of CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone/prednisolone) or etoposide plus (CHOEP).

Improvement of overall survival in advanced stage mantle cell lymphoma.

Purpose: Mantle cell lymphomas (MCLs) represent a clinically aggressive lymphoma subtype with a poor prognosis. To explore a potential progress in outcome a historical comparison was performed using data from the Kiel Lymphoma Study Group (KLSG; 1975 to 1986) and the German Low Grade Lymphoma Study Group (GLSG; 1996 to 2004).

Patients And Methods: All patients with the histologically confirmed diagnosis of advanced-stage nonblastoid MCL were eligible.

Equitoxicity of bolus and infusional etoposide: results of a multicenter randomised trial of the German High-Grade Non-Hodgkins Lymphoma Study Group (DSHNHL) in elderly patients with refractory or relapsing aggressive non-Hodgkin lymphoma using the CEMP regimen (cisplatinum, etoposide, mitoxantrone and prednisone).

To compare toxicity of etoposide bolus with continuous infusion and to assess the efficacy of the CEMP (cisplatinum, etoposide, mitoxantrone, prednisone) regimen, 47 patients with refractory or relapsed aggressive non-Hodgkin's lymphoma older than 60 years (n=43) or not qualifying for high-dose chemotherapy (n=4) received five four-weekly CEMP cycles. Patients were randomised to start with bolus or continuous-infusion etoposide and then received bolus and infusional etoposide in an alternating fashion. The primary objective was the comparison of differences in the course of leukocytopenia and thrombocytopenia between the two application schedules.

Six versus eight cycles of bi-weekly CHOP-14 with or without rituximab in elderly patients with aggressive CD20+ B-cell lymphomas: a randomised controlled trial (RICOVER-60).

Background: Cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) is used to treat patients with non-Hodgkin lymphoma. Interval decrease from 3 weeks of treatment (CHOP-21) to 2 weeks (CHOP-14), and addition of rituximab to CHOP-21 (R-CHOP-21) has been shown to improve outcome in elderly patients with diffuse large B-cell lymphoma (DLBCL). This randomised trial assessed whether six or eight cycles of R-CHOP-14 can improve outcome of these patients compared with six or eight cycles of CHOP-14.

A new prognostic index (MIPI) for patients with advanced-stage mantle cell lymphoma.

There is no generally established prognostic index for patients with mantle cell lymphoma (MCL), because the International Prognostic Index (IPI) and Follicular Lymphoma International Prognostic Index (FLIPI) have been developed for diffuse large cell and follicular lymphoma patients, respectively. Using data of 455 advanced stage MCL patients treated within 3 clinical trials, we examined the prognostic relevance of IPI and FLIPI and derived a new prognostic index (MCL international prognostic index, MIPI) of overall survival (OS). Statistical methods included Kaplan-Meier estimates and the log-rank test for evaluating IPI and FLIPI and multiple Cox regression for developing the MIPI.

Autologous tandem transplantation in patients with primary progressive or relapsed/refractory lymphoma.

Patients with primary progressive or refractory Hodgkin's disease (HD) or aggressive non-Hodgkin's lymphoma (NHL) have a particularly poor prognosis. Here we report the results of autologous tandem transplantation in these patients. Patients aged 18-55 years with primary progressive or refractory relapsed HD and aggressive NHL were included.
