Resum
BACKGROUND
More than 90 % of all patients with testicular germ cell tumours can be cured effectively. The mainstay of treatment is chemotherapy with cisplatin, etoposide and bleomycin (PEB). This regimen is usually well tolerated and does not lead to serious adverse events. Cardiovascular complications are encountered very rarely, but have gained increasing attention in recent years.
METHODS
A 33-year-old man with a testicular seminoma, clinical stage 2b, was subjected to PEB chemotherapy. At the end of the first treatment course, he had an acute ST-elevation myocardial infarction. Coronary angiography revealed a circumscribed stenosis of the left circumflex branch of the left coronary artery with intima dissection and thrombotic deposits. No atherosclerotic changes were found. Management consisted of placement of a drug-eluting coronary stent. Chemotherapy was discontinued and the seminoma treatment completed by radiotherapy with 30 Gy applied to the retroperitoneal mass and a paraaortic template. Complete remission was achieved. 6 months thereafter, the patient was doing well and was disease-free.
CONCLUSIONS
About 0.3 % of all testis cancer patients undergoing cisplatin-based chemotherapy develop cardiovascular complications. Cisplatin-related endothelial damage with secondary thrombotic clotting is assumed to be etiologic in these cases. As there is little comorbidity, the prognostic outlook is favourable in most cases. Caregivers in charge of testis cancer management should be vigilant regarding cardiovascular complications to ensure immediate diagnostic and therapeutic measures in incident cases.
