CT Scans in Treating Patients With Stage I Testicular Cancer After Undergoing Orchiectomy

This study has been completed.

National Cancer Institute (NCI) Identifier:
First received: November 1, 1999
Last updated: December 3, 2013
Last verified: December 2002

RATIONALE: Imaging procedures such as CT scans help the doctor in detecting cancer or the recurrence of cancer. Increasing the number of times a CT scan is given may improve the ability to detect stage I testicular cancer.

PURPOSE: Randomized clinical trial to determine if there is a different result from two different schedules of CT scans in treating patients with stage I testicular cancer after undergoing orchiectomy.

Condition Intervention
Testicular Germ Cell Tumor Procedure: computed tomography

Study Type: Interventional
Study Design: Allocation: Randomized
Primary Purpose: Diagnostic
Official Title: A Study of CT Scan Frequency in Patients With Stage I Testicular Teratoma

Estimated Enrollment: 900
Study Start Date: July 1997
Study Completion Date: April 2010
Detailed Description:


  • 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.

Patients are followed monthly for the first year after orchidectomy, then every 2 months for the second year, then every 3 months for the third year, and then every 4-6 months thereafter.

PROJECTED ACCRUAL: There will be 400-900 patients accrued into this study over 3-6 years.

  • Histologically confirmed nonseminomatous germ cell tumor of the testis Stage I disease:

    • No evidence of metastatic disease on clinical examination
    • Normal chest x-ray
    • Normal chest and abdominal CT scan
    • Normal serum tumor marker (AFP, HCG) after orchidectomy
  • High risk patients should be considered for ongoing studies of adjuvant chemotherapy after orchidectomy, but those choosing not to take this option may enter this study
  • Orchidectomy no greater than 8 weeks prior to randomization into this study
