Initial chemotherapy with mitoxantrone, chlorambucil, prednisone impairs the collection of stem cells in patients with indolent lymphomas—results of a randomized comparison by the German Low-Grade Lymphoma Study Group
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…
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 < …
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…
High Anti-Lymphoma Activity of Bendamustine/Mitoxantrone/Rituximab (BMR) in Rituximab Pretreated Relapsed or Refractory Indolent Lymphomas. A Multicentre Phase II Study of the German Low Grade Lymphoma Study Group (GLSG).
Abstract Purpose: Bendamustine is a new anti-lymphoma agent with promising activity. Based on a preceeding phase I study the current trial explored Bendamustine in combination with Mitoxantrone and Rituximab (BMR) in patients with relapsed or refractory indolent lymphomas. Patients and Methods: Patients with relapsed or refractory symptomatic stage III/IV indolent lymphomas with or without prior treatment with Rituximab were eligible. Therapy consisted of Bendamustine 90 mg/m2 days 1+2, Mitoxantrone 10 mg/m2 day 1, Rituximab 375 mg/m2 day 8. Treatment was repeated on day 29 for a total of 4 cycles. Results: Between 04/03 and 07/04 62 patients were recruited from 24 participating institution…
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…
High anti-lymphoma activity of bendamustine/mitoxantrone/rituximab in rituximab pretreated relapsed or refractory indolent lymphomas and mantle cell lymphomas. A multicenter phase II study of the German Low Grade Lymphoma Study Group (GLSG)
On the basis of a preceding phase I study, the current trial explored bendamustine in combination with mitoxantrone and rituximab (BMR) in patients with stage III/IV relapsed or refractory indolent lymphomas and mantle cell lymphoma (MCL) with or without prior rituximab containing chemo-immunotherapy (R-chemo) treatment. Therapy consisted of bendamustine 90 mg/m(2) days 1 + 2, mitoxantrone 10 mg/m(2) day 1, rituximab 375 mg/m(2) day 8. Treatment was repeated on day 29 for a total of four cycles. Between 3 April and 04 July, 57 patients were recruited from 24 participating institutions, 39% of whom had received prior R-chemo therapy. Median age was 66 years (40 - 83). Lymphoma subtypes were …
Clinicogenetic Risk Models in Patients Randomized to Receive Consolidative Autologous Stem-Cell Transplantation after Frontline R-CHOP for Advanced Follicular Lymphoma: An Analysis from the GLSG2000 Trial
Abstract Introduction: Advanced follicular lymphoma (FL) is a clinically and molecularly heterogeneous disease. About 20% of patients have early progression of disease (POD) and short overall survival (OS). We have previously shown that integration of lymphoma-specific gene mutations and clinical factors improves pretreatment risk stratification (Pastore, 2015) and prediction of early POD (i.e., within 24 months, POD24; Jurinovic, 2016). Recently, we have shown that high-dose therapy (HDT) followed by autologous stem-cell transplantation (ASCT) is an effective treatment option for eligible patients with high-risk disease as defined by POD24 (Jurinovic, 2018). Here, we aimed to explore wheth…
