Résumé
BACKGROUND: To determine the incidence of early cardiotoxicity induced by the CHOP regimen in patients with aggressive non-Hodgkin's lymphoma (NHL) and to identify associated risk factors. PATIENTS AND METHODS: A retrospective analysis included 135 consecutive patients who had been treated with the CHOP (cyclophosphamide, doxorubicin, vincristin, prednisone) regimen as first-line therapy between 1994 and 2000. The cardiac evaluation was based on a determination of the resting left ventricular ejection function (LVEF) by gated blood-pool imaging. Cardiotoxicity was defined as a significant decrease in LVEF or clinical evidence of congestive heart failure (CHF). RESULTS: Twenty-seven (20%) patients developed a cardiac event within 1 year of treatment. Among these, 14 patients had clinical signs of CHF. Three patients died suddenly from presumed cardiac causes. In multivariate analysis, a cumulative dose of doxorubicin >200 mg/m(2) [odds ratio (OR) = 4.2, P = 0.005)] and age over 50 years (OR = 2.9, P = 0.03) appeared to be significant risk factors. CONCLUSION: Early clinical and subclinical cardiotoxicity was frequent in patients receiving the CHOP regimen. The threshold of the cumulative dose of doxorubicin appeared to be low: at doses >200 mg/m(2), 27% of patients had cardiac events. Elderly patients appeared to be at higher risk. The development of cardioprotective strategies or alternative treatments are mandatory for aggressive NHL patients.
