INTRODUCTION: Pixantrone is a novel aza-anthracenedione with antineoplastic activity, currently approved for multiply relapsed/refractory diffuse large B-cell lymphoma (DLBCL), even if real-life data are limited.
METHODS: We investigated pixantrone efficacy and safety in clinical practice, as 3rd or 4th line therapy. We retrospectively analyzed a cohort of 37 R/R DLBCL patients managed in 8 Tuscan onco-hematological centers. Pixantrone, 50 mg/m2 , was administered on days 1, 8, 15 of a 28 days cycle for up to 6 cycles. Response to therapy was evaluated according to the Lugano 2014 classification.
RESULTS: Pixantrone was administered as 3rd or 4th line in 24/37 (64.9%) and 13/37 (35.1%) cases. Overall response rate and CR rate were 43.2% and 32.4%. After a median follow-up of 6 months, 17/37 patients (46%) were alive, the main cause of death was progressive disease (14/37 cases, 37.9%). Median PFS was 3 months, median DOR was 17.9 months, and median OS was 9.7 months. A significant proportion of patients achieved a long-lasting response >12 months (8/37 cases). IPI>2 showed a trend toward inferior PFS.
CONCLUSION: In this real-life setting, pixantrone demonstrated appreciable efficacy in a population with poor prognosis; in a small proportion of cases, it can be associated with long-term remission.
