Answer: Given pT1 pathology, patient is at low risk for tumor recurrence if he elects surveillance.

A large proportion of patients with non-seminomatous germ cell tumor is cured by orchiectomy alone. Vascular invasion (venous or lymphatic) has been shown to be most important predictor of tumor recurrence following orchiectomy.1 

Furthermore, pT1 (Stage IA) staging indicates that vascular invasion is not present. As such, if a patient elects surveillance chances of tumor recurrence are on the order of 15%.2, 3

The case was prepared by Alexander Kutikov, MD, of Fox Chase Cancer Center in Philadelphia.
