Our aim was to analyze treatment results and survival characteristics of our patients with malignant sacrococcygeal germ cell tumors. Patient files of children with malignant sacrococcygeal germ cell tumors, treated at our institution between 1979 and 2009, were searched. Patient characteristics, histopathological subtypes, extension of disease, alpha-fetoprotein (AFP) level at the time of diagnosis and relapse, extent of surgical resection, chemotherapy protocols, details of radiotherapy and survival characteristics were recorded. A total of 58 patients (M/F = 20/38) with malignant sacrococcygeal germ cell tumor was included in analysis. With a mean follow-up of 156 months (range, 26 days to 288.8 months) overall and event-free survival rates of the 58 patients were 50.9% and 43.8%, respectively. AFP status of the patients (37% in patients with
