Germ cell tumors of undescended vs. descended testes: Population-based clinical and outcomes data

Our results support recent literature revealing seminomas are more frequent in cryptorchid testes. RT was equally used between localized UDT and DT seminomas. Penetrance of RadOrch is similar in local and regional disease by histology. Survival is equivalent for UDT compared to DT lesions in both seminomatous and NSGCT histologies.
