Testicular cancer patients have an increased risk for coronary artery disease more than ten years after cisplatin-based chemotherapy. We investigated whether vascular changes, including endothelial dysfunction, are present earlier. Ninety chemotherapy-treated testicular cancer patients (median follow-up of seven years) were compared with 44 patients after orchidectomy only and 47 healthy men. Microalbuminuria was present in 10 (12%) chemotherapy patients, one stage I patient and none of the controls. Chemotherapy patients had higher levels of fibrinogen, C-reactive protein (hs-CRP), von Willebrand factor (vWF), plasminogen activator inhibitor (PAI-1), and tissue-type plasminogen activator (t-PA). Chemotherapy patients with elevated PAI-1 (25/90) showed clustering of cardiovascular risk factors resembling the metabolic syndrome. In conclusion, cured testicular cancer patients showed a high prevalence of microalbuminuria and increased plasma levels of endothelial and inflammatory marker proteins, which might progress to more severe endothelial dysfunction and overt atherosclerosis.
