Current treatment recommendations include cisplatin based chemotherapy up front but the recommendations are based on limited single center series.Results: The elevated prechemotherapy tumor markers were α-fetoprotein in 48% of cases, β-human chorionic gonadotropin in 14%, and α-fetoprotein and β-human chorionic gonadotropin in 38%. Median α-fetoprotein and β-human chorionic gonadotropin values were 71 ng/ml and 80 mIU/ml, respectively. The IGCCCG (International Germ Cell Cancer Collaborative Group) prognostic classification was good in 94% of cases. Mixed nonseminomatous germ cell tumor was found in 78% of cases. Of the patients 103 achieved a complete response to chemotherapy. In 6 patients radiological signs of progressive disease developed during chemotherapy, while 8 experienced relapse after an initial complete response. At a median followup of 108 months 108 patients were alive and disease-free. Five and 10-year disease-free survival rates were 87% and 85%, respectively. The predominance of embryonal carcinoma in the primary tumor was the only factor associated with the probability of needing additional therapy.Stage IS testicular cancer is more commonly associated with elevated α-fetoprotein, an IGCCCG good prognosis and mixed nonseminomatous germ cell tumor. Treatment with cisplatin based chemotherapy leads to cure in most cases.
