Dose escalation of epirubicin in the CEOP-BLEO Regimen: A Controlled clinical trial comparing standard doses for the treatment of diffuse large cell lymphoma

One hundred and forty-seven consecutive patients with previously untreated high-intermedium and high clinical risk diffuse large cell lymphoma (DLCL) were included in a prospective clinical trial to evaluate the efficacy and toxicity of escalating doses of epirubicin compared to standard doses in the CEOP-Bleo (cyclophosphamide, epirubicin, vincristine and prednisone and bleomycin) regimen. 55% of the patients were > 60 years old and most patients had adverse prognostic factors at diagnosis. Complete response rates were similar in both groups (68% in the standard dose compared to 73% in the escalating arm, (p = 0.5). However, time to treatment failure (TFF) and overall survival were better after escalating doses. At 3-years TTF at a median follow-up of 33.6 months was 76% in the patients whose received escalating dose statistical different to 37% of the patients whose received standard doses (p
