Allogeneic Stem Cell Transplant Versus Tandem High-Dose Melphalan for Front-Line Treatment of Deletion 13q14 Myeloma – An Interim Analysis of the German DSMM V Trial.

Abstract Abstract 51 Background Allogeneic stem cell transplantation (allo SCT), a treatment modality based on transfer of immunocompetent donor lymphocytes offers curative potential to subjects with a variety of hematological cancers. In multiple myeloma (MM), high-dose melphalan followed by autologous stem cell transplantation (auto SCT) is adopted as a standard of care. However, it remains palliative since virtually all patients (pts) relapse and renders allo SCT an option of interest. Deletion of chromosome 13q14 (13q-) in MM has been shown to negatively impact prognosis. Therefore, improvement of therapy for 13q- pts is highly desirable. Patients and methods A prospective two-arm multi…

Kinetics of Renal Function during Induction in Newly Diagnosed Multiple Myeloma: Results of Two Prospective Studies by the German Myeloma Study Group DSMM

Background: Preservation of kidney function in newly diagnosed (ND) multiple myeloma (MM) helps to prevent excess toxicity. Patients (pts) from two prospective trials were analyzed, provided postinduction (PInd) restaging was performed. Pts received three cycles with bortezomib (btz), cyclophosphamide, and dexamethasone (dex

Phase II study of bortezomib, cyclophosphamide and dexamethasone as induction therapy in multiple myeloma: DSMM XI trial.

Summary We assessed the safety and efficacy of bortezomib, cyclophosphamide and dexamethasone (VCD) induction therapy in previously untreated multiple myeloma patients. A total of 414 patients received three 21-day cycles of VCD prior to autologous stem-cell transplantation (ASCT). Most common grade ≥3 adverse events were leucopenia (31·4%) and thrombocytopenia (6·8%). The overall response rate (ORR) by investigator-based assessment was 85·4%. Most patients (74%) underwent successful central laboratory-based molecular cytogenetic analysis. No clinically relevant differences in ORR post-induction were seen between patients with or without high-risk cytogenetic abnormalities (86·2% vs. 84·3%)…

Combined Immuno-Chemotherapy (R-CHOP) Results in Significantly Superior Response Rates and Time to Treatment Failure in First Line Treatment of Patients with Lymphomplasmocytoid/ic Immunocytoma (LP-IC) - Results of a Prospective Randomized Trial of the German Low Grade Lymphoma Study Group (GLSG).

Abstract Lymphomplasmocytoid/ic immunocytoma (LP-IC), including Waldenstrom’s macro-globulinemia and lymphoplasmacytoid lymphoma according to the Kiel classification (the latter one subsummed as a variant of B-CLL in the WHO classification), is an indolent lymphoma, which is incurable by conventional chemotherapy in the advanced stage of disease. The anti-CD20 antibody Rituximab has shown remarkable activity in indolent lymphomas, in particular when combined with chemotherapy. Based on these results the GLSG investigated the efficacy of a combined immuno-chemotherapy (R-CHOP: Rituximab 375 mg/m2 d0-1; cyclophosphamide 750 mg/m2 d1; doxorubicine 50 mg/m2 d1; vincristine 1.4 mg/m2 d1; prednis…

Rituximab in Combination with CHOP in Patients with Follicular Lymphoma: Analysis of Treatment Outcome of 552 Patients Treated in a Randomized Trial of the German Low Grade Lymphoma Study Group (GLSG) after a Follow up of 58 Months

Abstract We have previously reported that compared to CHOP alone the addition of Rituximab (R) to CHOP significantly increases the response rate (RR), the time to treatment failure (TTF) and also the overall survival (OS) in patients with newly diagnosed advanced follicular lymphoma. However, in the previous report, the median observation time was short with 18 months and no data were reported on the outcome of different risk groups according to the FLIPI (Hiddemann et al., Blood 2005). We now report on the treatment outcome of 552 patients with advanced stage follicular lymphoma randomized between R-CHOP versus CHOP alone after a median follow up of 58 months. Responding patients < …

Velcade, Intravenous Cyclophosphamide and Dexamethasone (VCD) Induction for Previously Untreated Multiple Myeloma (German DSMM XIa Trial).

Abstract 131 Introduction. Autologous stem cell transplantation (ASCT) after cytoreductive induction is considered standard of care for younger patients (pts) with multiple myeloma (MM). The previous standard of induction, the Vincristin-Adriamycin-Dexamethasone (VAD) combination, achieves inferior results compared with induction regimens which combine the proteasome inhibitor Velcade (V = Bortezomib) with Dexamethasone (D)(=VD) and a cytostatic drug such as Doxorubicin (PAD = VD plus Doxorubicin). Velcade-based induction therapy was shown to translate into better myeloma control after high dose melphalan and to lead to prolonged progression-free survival. In order to find a more efficaciou…

CHOP Improves Response Rates but Not Overall Survival in Follicular and Mantle Cell Lymphoma (MCL)- Results of a Randomized Trial of the German Low Grade Lymphoma Study Group (GLSG).

Abstract In advanced stage follicular lymphoma conventional chemotherapy is non-curative and no major improvement in overall survival has been achieved by different regimens. Similarly, MCL, a lymphoma subtype with an especially poor clinical outcome, cannot be cured by conventional chemotherapy. In 1996, the German Low Grade Lymphoma Study Group (GLSG) started a randomized trial to evaluate the efficacy of two different anthracycline/anthrachinon containing regimens comparing CHOP (cyclophosphamide 750 mg/m2 day 1, vincristine 1.4 mg/m2 day 2, adriamycine 50 mg/m2 day 1, prednisone 100 mg/m2 days 1–5) and MCP (mitoxantrone 8 mg/m2 days 1–2, chlorambucil 3x3 mg/m2 days 1–5; prednisone 25 mg…

The addition of rituximab to front-line therapy with CHOP (R-CHOP) results in a higher response rate and longer time to treatment failure in patients with lymphoplasmacytic lymphoma: results of a randomized trial of the German Low-Grade Lymphoma Study Group (GLSG)

Lymphoplasmacytic lymphoma (LPL) is an indolent lymphoma with moderate sensitivity to conventional chemotherapy. This study investigated whether the addition of rituximab to standard chemotherapy improves treatment outcome in LPL and the subgroup of LPL patients fulfilling the criteria of Waldenstroem's macroglobulinemia (WM). A total of 69 patients with previously untreated LPL were enrolled into the trial; 64 patients were evaluable for treatment outcome. In all, 48 of the 64 LPL patients fulfilled the criteria of WM. Patients were randomly assigned to R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone, n=34) or CHOP (n=30). R-CHOP resulted in significantly highe…
