Introduction: The role of positron emission tomography (PET) with 2-[18F]fluoro-2-deoxy-D-glucose ([18F]FDG) is currently under evaluation in urologic oncology. The aim of the present study was to investigate the use of [18F]FDG positron emission tomography ([18F]FDG-PET) in the detection and treatment control of malignant germ cell tumors compared to computed tomography (CT).

Materials And Methods: Thirty-two PET studies and CT scans were carried out in 23 patients with histologically proven germ cell tumors (10 seminomas, 12 non-seminomatous germ cell tumors (NSGCT), 1 unclassified serologic recurrent disease) Lugano stage I-III.

Background: Although successful xenotransplantation of human tumors in nude mice highly predicts prognosis, little is known regarding the biologic background of this correlation. In this study, the relationship between the macroscopic growth pattern of first-generation xenografts of human renal cell carcinomas in nude mice and prognosis was studied.

Methods: Macroscopic growth patterns of the first-generation xenografts of locally confined renal cell carcinomas were analyzed according to the best-fit Gompertz recursion formulas.

Background: The prognosis of patients with locally confined renal cell carcinoma is variable. To improve the prognostic knowledge and select patients at high risk, additional prognostic parameters are needed.

Methods: The significance with respect to survival and tumor recurrence of "classic" and "new" prognostic parameters has been examined by following 41 patients with locally confined renal cell carcinoma after nephrectomy (mean follow-up, 5.
