Anthracyclines remain as the best drugs in the treatment of patients with aggressive malignant lymphoma in combination with other cytotoxic drugs. However, dose escalation is poorly tolerated and acute and late cardiac toxicity has limited the use of these compounds. Pegylated liposomal doxorubicin has been proven to be useful in some malignancies, without the presence of acute cardiac toxicity and with a good response rate in patients with relapsed/refractory lymphomas. We report the first study of this drug in combination chemotherapy in patients with previously untreated aggressive malignant lymphoma. Twenty consecutive patients with diagnosis of diffuse large-B-cell lymphoma, age < 18 yr to < 70 yr, without previous treatment, HIV-negative high and high-intermediate clinical risks were treated with the CHOP-Bleo regimen at standard doses, using pegylated-liposomal doxorubicin instead of doxorubicin, at 25 mg/m2 (3 patients), 30 mg/m2 (3 patients), and 35 mg/m2 (14 patients). Complete response was achieved in 17 cases (85%), with failure in 3 patients (15%). At a median follow-up of 18.1 mo, relapse has not been observed. Two patients died secondary to tumor progression. Toxicity was mild, only three episodes of granulocytopenia grade I were observed, and no mucositis, thrombocytopenia, or granulocitopenia grade > 2 was observed. Erythrodisestesias grade II was observed in one case and grade I in two cases. Cardiac function was normal before and 12 mo after chemotherapy. Pegylated liposomal doxorubicin appear as an promising drug in the treatment of patients with aggressive malignant lymphoma.
