Purpose of reviewTo review current developments in the management of patients with testicular cancer, with special emphasis on risk factors for the primary tumour and treatment options for clinical stage I testicular germ cell tumours.Recent findingsThe management of patients with testicular cancer has substantially improved over the past 25 years. Current concepts for treating localized and regional disease have been influenced by effective systematic chemotherapy. At present, cure rates approach nearly 100% for low-stage disease and more than 80% for advanced disease.SummaryRetroperitoneal lymph node dissection is still favoured as the therapy of choice for clinical stage I non-seminomatous germ cell tumours in many centres, but as risk factors for the primary tumour have become better understood, surveillance and risk-adapted therapy, including surveillance for low-risk patients and adjuvant chemotherapy for the high-risk group, is now being considered a therapeutic option particularly in European centres. Adjuvant radiotherapy is still the gold standard for the treatment of patients with clinical stage I seminoma, but the relapse rate of 19% and a 5-year overall survival of 97.7% make surveillance a possible therapeutic option. The results of phase II and III trials should soon provide additional information on carboplatin for single-agent adjuvant chemotherapy.
