Bendamustine is an effective treatment for lymphoid malignancies and its role continues to expand. To determine the long-term sequelae associated with bendamustine, 194 patients treated with bendamustine (most commonly with rituximab) were retrospectively reviewed. The rate of secondary malignancies was minimal and no therapy-related myelodysplastic syndrome or acute myelogenous leukemia were reported. No deaths from infection were attributable to bendamustine.


Bendamustine, typically in combination with rituximab, is an effective treatment for chronic lymphocytic leukemia (CLL) and B-cell non-Hodgkin lymphoma. Despite its acceptable short-term toxicity profile, long-term toxicities are less well established. This study investigated the long-term adverse effects of bendamustine and responses to subsequent treatments.

Patients and Methods:

Charts of 194 patients were retrospectively reviewed; 54% had received prior treatment (76% attained complete response [CR] or partial response [PR]).


Patients who did not achieve a CR or PR did not respond well to subsequent treatments. Malignancies following bendamustine were diagnosed in 11% (21) of patients (first line [7] and salvage [14]), including squamous (8) or basal cell (4) skin cancers; prostate cancer (3), renal cancer (3), bladder cancer (2), melanoma (2), lung cancer (1), and histiocytic sarcoma (1). There were no occurrences of therapy-related myelodysplastic syndrome or acute myelogenous leukemia reported. Infections occurred in 63% of patients; however, no deaths were attributable to bendamustine.


Bendamustine is an effective therapy with limited long-term sequelae in patients with lymphoid malignancies.
