Prognostic model for newly diagnosed CLL patients in Binet stage A: results of the multicenter, prospective CLL1 trial of the German CLL study group.

The heterogeneity of early stage CLL challenges prognostication, and refinement of prognostic indices for risk-adapted management in this population is essential. The aim of the multicenter, prospective CLL1 trial was to explore a novel prognostic model (CLL1-PM) developed to identify risk groups, separating patients with favorable from others with dismal prognosis. A cohort of 539 clinically, biochemically, and genetically characterized Binet stage A patients were observed until progression, first-line treatment, or death.

Bendamustine plus mitoxantrone for relapsed/refractory chronic lymphocytic leukaemia (CLL): results of a multicentre phase II study of the German CLL Study Group (GCLLSG).

The efficacy of bendamustine (50 mg/m², days 1-3) plus mitoxantrone (10 mg/m², day 1), every 28 days for up to four courses, was evaluated in a Phase II multicentre trial enrolling 59 patients with relapsed or refractory B-cell chronic lymphocytic leukaemia (CLL). Major toxicities were grade 3/4 leucopenia, thrombocytopenia and infections in 42%, 12% and 12% of patients, respectively. Complete and partial response was achieved in 5/59 and 25/29 patients, respectively (overall response rate, 51%).
