Evidence has emerged that patients cured with cisplatin-bleomycin chemotherapy from disseminated testicular cancer (TC) develop a large number of cardiovascular risk factors (CRF) several years later. Recently, we observed an increased incidence of cardiac events 10-20 years after chemotherapy, possibly as a result of increased occurrence of CRF. Additional cardiovascular damage was observed after treatment: disturbed diastolic function of the left ventricle, microalbuminuria and increased endothelial damage parameters. Furthermore, a metabolic syndrome (syndrome X) with insulin-resistance, dyslipidemia, hypertension and endothelial damage was found in about one third of our cured patients. The investigators hypothesize that endothelial damage and metabolic changes caused by the bleomycin and cisplatin chemotherapy are the main causes for the observed increase in cardiovascular disease in these young cancer survivors. Genetic susceptibility may be an important determinant of individual risk of toxicity in individual patients.
