Early autologous stem cell transplantation for chronic lymphocytic leukemia: long-term follow-up of the German CLL Study Group CLL3 trial.

The CLL3 trial was designed to study intensive treatment including autologous stem cell transplantation (autoSCT) as part of first-line therapy in patients with chronic lymphocytic leukemia (CLL). Here, we present the long-term outcome of the trial with particular focus on the impact of genomic risk factors, and we provide a retrospective comparison with patients from the fludarabine-cyclophosphamide-rituximab (FCR) arm of the German CLL Study Group (GCLLSG) CLL8 trial. After a median observation time of 8.

Long-term outcome of hemizygous and heterozygous carriers of a germline GATA1 (G208R) mutation.

The transcriptional regulator GATA1 is crucially involved in megakaryocytopoiesis and erythropoiesis. Mutations of the gene which is located on the X chromosome have been associated with platelet and red blood cell abnormalities. We identified a family with a GATA1 (G208R) mutation in whom a low male birth rate and frequent miscarriages among heterozygous females suggested increased fetal death in male hemizygotes.

First-line therapy with fludarabine compared with chlorambucil does not result in a major benefit for elderly patients with advanced chronic lymphocytic leukemia.

Although chronic lymphocytic leukemia (CLL) is a disease of elderly patients, subjects older than 65 years are heavily underrepresented in clinical trials. The German CLL study group (GCLLSG) initiated a multicenter phase III trial for CLL patients older than 65 years comparing first-line therapy with fludarabine with chlorambucil. A total of 193 patients with a median age of 70 years were randomized to receive fludarabine (25 mg/m(2) for 5 days intravenously, every 28 days, for 6 courses) or chlorambucil (0.

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.

Repp86: a new prognostic marker in mantle cell lymphoma.

Objectives: Proliferation indices are important prognostic factors for the clinical outcome of patients with mantle cell lymphoma (MCL). We investigated whether the expression of repp86 (restrictedly expressed proliferation-associated protein 86 kDa), a new proliferation specific marker expressed in the cell cycle phases G(2), S and M, but not in G(1), correlates with the clinical course in patients with MCL.

Patients And Methods: Biopsy specimens from 94 untreated patients enrolled in two multicenter trials were investigated immunohistochemically with monoclonal antibodies against CD20, CD5, CD3, CD23, cyclin D1, and repp86 (Ki-S2).
