Resumen: The use of non-pegylated liposomal doxorubicin (Myocet®) in diffuse large B-cell lymphoma (DLBCL) has been investigated in retrospective and single-arm prospective studies. This was a prospective phase 2 trial of DLBCL patients =60 years old with left ventricular ejection fraction (LVEF) =55% randomized to standard R-CHOP or investigational R-COMP (with Myocet® instead of conventional doxorubicin). The primary end point was to evaluate the differences in subclinical cardiotoxicity, defined as decrease in LVEF to <55% at the end of treatment. Secondary objectives were efficacy, safety, and variations of troponin and N-terminal pro-B-type natriuretic peptide (NT-proBNP) and LVEF along follow-up. Ninety patients were included, 45 in each group. No differences were observed in the percentage of patients with LVEF <55% at end of treatment (11% in R-CHOP arm vs. 7% in R-COMP arm, p = 0.697) or at 4 months (10% vs. 6%, respectively, p = 0.667) and 12 months (8% vs. 7%, respectively, p = 1). However, a higher percentage of R-CHOP compared with R-COMP patients showed increased troponin levels in cycle 6 (100% vs. 63%, p = 0.001) and at 1 month after treatment (88% vs. 56%, respectively, p = 0.015). Cardiovascular adverse events were seen in five R-CHOP patients (nine episodes, four grade =3) and in four R-COMP patients (five episodes, all grade 1–2). No significant differences in efficacy were observed. In conclusion, R-COMP is a feasible immunochemotherapy schedule for DLBCL patients =60 years, with similar efficacy to R-CHOP. However, the use of non-pegylated doxorubicin instead of conventional doxorubicin was not associated with less early cardiotoxicity, although some reduced cardiac safety signals were observed.
