Sub-centimeter lymphadenopathy in germ cell testicular cancer: An ongoing surveillance challenge.

e17011 Background: Correct identification of retroperitoneal disease is essential for proper staging and management in germ cell tumors. A size threshold of a 10mm diameter has high specificity in assessing nodal metastases, but sensitivity can be poor at this level and many patients have sub-centimeter lymphadenopathy on post-orchidectomy staging. As many staging scans are done soon after surgery, these may represent reactive lymph nodes. We...
