Bendamustine is an established treatment option in chronic lymphocytic leukemia (CLL) and frequently used in Austria and Italy. 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.

Abstract

Bendamustine is an established treatment option in chronic lymphocytic leukemia (CLL) and frequently used in Austria and Italy. 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.
