A Clinical Trial of Primary Retroperitoneal Lymph Node Dissection in Patients With Testicular Seminoma With Limited Retroperitoneal Metastases

This trial is studying whether surgery to remove lymph nodes in the back of the abdomen (retroperitoneal lymph node dissection) is a better treatment option for men with testicular seminoma — a type of testicular cancer — that has spread in a limited way to nearby lymph nodes. The goal is to see if surgery can replace radiation or chemotherapy in these early-spread cases. **You may be eligible if...** - You are an adult male with a confirmed diagnosis of testicular seminoma - Your cancer has spread to lymph nodes behind the abdomen, but only in a limited way (small metastases) - You have not yet received treatment for this spread (treatment-naive) - You are in good enough health to undergo surgery **You may NOT be eligible if...** - Your cancer has spread widely or to distant organs - You have already received chemotherapy or radiation for this cancer - You have serious other health conditions that make surgery too risky - You have a different type of testicular cancer (non-seminoma) Talk to your doctor to see if this trial is right for you.
