Background To assess the efficacy and safety of the combination of non‐pegylated liposome‐encapsulated doxorubicin (Myocet®) with cyclophosphamide, vincristine, prednisone and rituximab (R‐COMP) in patients with aggressive non‐Hodgkin's B‐cell lymphomas. Methods Twenty‐one patients were selected for the presence of negative concurrent clinical features such as cardiac comorbidity and/or previous treatment with anthracycline‐based regimens. Liposome‐encapsulated doxorubicin at a dose of 50 mg/m 2 was administered in association with cyclophosphamide (750 mg/m 2 ), vincristine (1.4 mg/m 2 ), prednisone (40 mg/m 2 ) and rituximab (375 mg/m 2 ) every 21 days for four to six cycles unless progression or unacceptable toxicity occurred. Results A complete response (CR) was obtained in 16/21 patients (76%), three patients achieved a partial response (14%), with an overall response rate of 90%. Two patients (10%) did not respond to therapy. After a median follow‐up of 13 months (range 2–36 months), 2/16 CR patients relapsed, with a disease‐free survival (DFS) of 78%. Conclusions The replacement of doxorubicin with its non‐pegylated liposomal pharmaceutical analogue was well tolerated and highly effective in inducing remission in this group of patients at high risk for cardiac toxicity or previously treated with anthracyclines. Its high tolerability and low incidence of cardiac events (only one patient) warrants further studies to confirm the clinical benefits of liposomal doxorubicin in this subset of patients.
