Evaluation of acute and early cardiotoxicity in survivors of Hodgkin's disease treated with ABVD or BEACOPP regimens.

The study was conducted to compare the presence of cardiotoxicity after the treatment of Hodgkin's disease with the standard ABVD or BEACOPP protocol. We examined 29 patients treated by means of the ABVD regimen and 34 treated with the BEACOPP regimen. Using rest echocardiography we assessed the left ventricular function before and after the therapy. One year after the completion of therapy, a control examination was performed with a battery of tests; the rest and dynamic stress echocardiography and cardiopulmonary tests were carried out to assess cardiopulmonary performance. A similar significant deterioration of ejection fraction and diastolic function was apparent after the treatment in both sub-groups with a further progression at the one-year control. Only one patient from the BEACOPP sub-group showed a pathological drop of EF <50%. The most affected parameters of left ventricular function (LV) were Doppler indices. We found a significant relationship of the parameters of LV function compared with age, the cumulative dose of doxorubicin and the cumulative dose of radiotherapy. Multivariate analysis demonstrated that diastolic dysfunction correlated with advanced age and the cumulative dose of doxorubicin, and decreased cardiopulmonary performance with advanced age, radiotherapy, and female gender. Both parameters were significantly influenced by the presence of hypertension. The used regimens demonstrated similar subclinical cardiotoxicity, thus the most aggressive regimen, BEACOPP, is not accompanied by a higher rate of cardiac impairment. The clinical value of such subclinical cardiotoxicity will be estimated in a further prospective follow-up.
