Fig. 2. (A) The OS of patients who responded to bendamustine was significantly better than that of patients who did not. (B) Performance status at the time of bendamustine treatment was significantly associated with OS. (C) Patients ≤60 years old at the time of bendamustine treatment showed a trend towards better OS. (D) The median number of lines prior to bendamustine treatment was not associated with OS.
