Clinical experience of bendamustine in relapsed or refractory Hodgkin lymphoma: a retrospective analysis of the French compassionate use program in 28 patients

Limited data support the use of bendamustine in Hodgkin lymphoma (HL). This retrospective study evaluated the efficacy and toxicity of bendamustine in 28 patients with refractory HL or relapsed HL after autologous stem cell transplant (ASCT) used as part of a compassionate use program. The median number of therapies before bendamustine was 5 (3-8). ASCT and non-myeloablative allogeneic transplant were previously performed for 25 and six patients, respectively. The median number of bendamustine cycles administered was 3 (1-12). The objective response rate was 50% with complete response (CR) in 29% of patients. The median progression-free survival was 5.7 months, and 10.2 months in patients with CR. During the first six cycles, two patients had a febrile neutropenia and four patients had grade 3-4 thrombocytopenia. Bendamustine was effective in these highly pretreated patients with HL. It might be used earlier in the treatment strategy of HL and in combination with other active drugs.
