Assessment of the Utility of CT Follow Up in the Long Term Follow Up of Patients With Metastatic Non Seminomatous Germ Cell Tumour (NSGCT)

Brief Summary

Detailed Description

OBJECTIVES: * To assess the frequency of relapse or recurrent abnormalities detected by CT scan in patients on long-term follow-up for metastatic nonseminomatous germ cell tumour (NSGCT). * To assess the utility of CT scan-assessment in these patients. * To assess the prognostic factors predictive of late relapse in NSGCT. OUTLINE: This is a multicenter study. Patients are screened by CT scan of the chest, abdomen, and pelvis for detectable abnormalities or indications of late relapse. Scans are classified as positive or negative, according to standard CT criteria, by a radiologist with expertise in testicular cancer imaging. Patients with negative scans are followed yearly by clinical examination and tumor marker assessment, and every 5 years by CT imaging. Additional follow-up is performed at the discretion of the attending physician. Patients with positive scans undergo confirmation of relapse, whenever possible, by surgical excision or biopsy and treatment is initiated according to best clinical practice. If the follow-up scan is equivocal, patients are advised to have a follow-up scan of the affected region in 6 months.

Primary Outcomes

Secondary Outcomes

• Rate of false positive abnormalities not due to NSGCT but due to benign process
• Rate of relapse following initial CT scan
• Number of abnormalities detected on second CT scan
