title: Management of patients with clinical stage I nonseminomatous germ cell testicular cancer: Active surveillance versus adjuvant chemotherapy - single-centre experience.
abstract: Surveillance after orchiectomy alone has become popular in the management of clinical stage I nonseminomatous germ cell testicular tumors (CSI NSGCTT). Efforts to identify patients at high risk of disease progression led to a search for risk factors in CSI NSGCTT. The aim of the present study was to analyse single-centre experience with risk-adapted therapeutic approaches (active surveillance versus adjuvant chemotherapy). From 1/1992 to 12/2013 a total of 431 CSI NSGCTT patients were included in the study and stratified into two groups according to risk-adapted therapeutic approaches. Group A (low-risk CSI NSGCTT) consisted of 276 patients who underwent active surveillance, progression of disease occurred in 46 (16.7%) patients with a median follow-up of 7.2 months. Six patients (2.2 %) of this group died with a median follow-up of 34.3 months. Group B (high-risk CSI NSGCTT) consisted of 155 patients who were treated with adjuvant chemotherapy, disease progression occurred in two (1.3 %) of them with a median follow-up of 56.2 months. One patient (0.6 %) died 139.4 months following orchiectomy. Overall survival rate of all CSI NSGCTT patients in both groups was 424/431 (98.4 %) with median follow-up of 130.4 months following orchiectomy. Surveillance policy is recommended only in patients with low-risk CSI NSGCTT.
