A Study of CT Scan Frequency in Patients With Stage I Testicular Teratoma

OBJECTIVES:

• Determine whether there is a difference between two schedules of CT scan surveillance in respect to stage of disease at relapse, survival, the investigation determining relapse, and incidence of second malignancies in patients with stage I testicular teratoma after orchidectomy.

OUTLINE: This is a randomized, multicenter study. Patients are stratified by center and presence of vascular invasion.

After orchidectomy, patients are randomized into two schedules (arms I and II) of CT scan follow up.

• Arm I: Patients repeat chest and abdominal CT scans no later than 3 months after orchidectomy and again at 12 months to confirm that the patient is clear of disease.
• Arm II: Patients repeat chest and abdominal CT scans at 3, 6, 9, 12, and 24 months after orchidectomy.
