Therefore, we analyzed 100 unselected, consecutive patients with CLL (treatment-naïve and relapsed/refractory) receiving bendamustine in a real-life setting. Most patients were treated with bendamustine in combination with rituximab (BR). However, bendamustine monotherapy was additionally evaluated. Patients treated with BR had a significantly higher overall response rate of 76% (complete response=22%) when compared to those treated solely with bendamustine (overall response rate=50%; complete response=13%). Overall survival (OS) and progression -ree survival (PFS) were significantly lower in the bendamustine-treated group (OS=14.3 months; PFS=8.3 months) compared to the BR group (OS=42.7; PFS=22.5 months; both p<0.001). In multivariate analysis, patients with a good cytogenetic risk and those receiving BR had a significantly better OS. Grade 3/4 hematological complications were seen in 32% of the patients. Hence, bendamustine, especially in combination with rituximab, is an effective therapy with manageable toxicity for non-selected patients with CLL including those pre-treated with fludarabine and the elderly.
