Brief summary
RATIONALE: Imaging procedures such as positron emission tomography may improve the ability to detect the extent of cancer and allow doctors to plan more effective treatment for patients who have testicle cancer. PURPOSE: Diagnostic trial to study the effectiveness of positron emission tomography using fludeoxyglucose F 18 in predicting relapse in patients who have stage I germ cell tumor of the testicle.
Detailed description
OBJECTIVES: * Assess the ability of fludeoxyglucose F 18 positron emission tomography to predict relapse requiring adjuvant chemotherapy in patients with high-risk stage I non-seminomatous or mixed seminoma/non-seminomatous germ cell tumor of the testis who are on current management protocols. OUTLINE: This is a multicenter study. Patients receive fludeoxyglucose F 18 (FDG) IV followed 1 hour later by positron emission tomography (PET) imaging. Patients with metastatic disease identified by FDG PET imaging may receive adjuvant chemotherapy according to the standard clinical practice at each participating center. Patients with no metastatic disease identified by FDG PET imaging are considered for entry into the MRC-TE08 trial (randomized trial of 2 CT scan frequencies in the surveillance of stage I teratoma) or are followed according to the standard surveillance schedule. Patients with metastatic disease are followed every 6 months. Patients with no metastatic disease are followed monthly for 1 year, every 2 months for 1 year, every 3 months for 1 year, and then every 4-6 months thereafter. Peer Reviewed and Funded or Endorsed by Cancer Research UK PROJECTED ACCRUAL: Approximately 135 patients will be accrued for this study within 2-3 years.
