Diagnostic Role of Circulating microRNAs in Small Testicular Masses Suitable for Testis Sparing Surgery and Post-chemotherapy Residual Masses Suitable for Retroperitoneal Lymph Node Dissection.
The purpose of this study is to evaluate the diagnostic performance of circulating microRNAs in detecting the presence of germ cell cancer in patients with small testicular mass or retroperitoneal post-chemotherapy residual mass and suitable for testis sparing surgery and retroperitoneal lymph node dissection, respectively.
