Echocardiography is a sensitive method for detecting wall motion abnormalities, as well as for monitoring cardiotoxicity during treatment with anthracyclines. Using echocardiography, this study investigated possible acute cardiotoxicty associated with primary treatment of Hodgkin's disease according to German Hodgkin's Lymphoma Study Group (GHSG) clinical trial protocols for adults. A group of 88 patients (48 men) was registered in the prospective, randomized clinical trial involving the treatment of Hodgkin's disease using third and fourth generation GHSG protocols. These patients were monitored by echocardiography. The average age was 34 years (range, 18-65; median, 32). The average anthracycline dose was 174 mg/m2 (median 200 mg/m2), and the average mediastinum irradiation dose was 21 Gy (median 30 Gy). Left ventricle end-systolic diameter (ESD) and left ventricle end-diastolic diameter (EDD), as well as fractional shortening (FS) and ejection fraction (EF) (M-mode calculation) were evaluated, as was the presence of pericardial effusion and wall motion abnormalities. The examinations were conducted before and at the end of therapy (up to 2 months). Results show that all evaluated parameters changed from one follow-up examination to the other, but these changes did not reach statistical significance. ESD increased from 30 +/- 4 to 31 +/- 4 mm. EDD increased from 49 +/- 4 to 49 +/- 5 mm. Ejection fraction changed from 69 +/- 7 to 66 +/- 7% and fractional shortening was unchanged (from 38 +/- 7 to 38 +/- 7%). In seven patients (8%), we observed new wall motion abnormalities characterized by hypokinesis without decrease of left ventricular function. Significant changes in the amount of pericardial effusion were not observed. In four patients (5%), there was progression of Hodgkin's disease. In conclusion, treatment according to third and fourth generation clinical trial protocols of the GHSG leads only to minimal wall motion changes, without concomitant reduction of left ventricular function, thus not meeting the criteria, acute cardiotoxicity.
