Using advanced MRI to study brain changes in testicular cancer patients with low testosterone

A Pilot Study of 7 Tesla MRI Neuroimaging in Testicular Cancer Patients With Hypogonadism and Androgen Replacement Therapy

University of Southern California · NCT06191575

This study is testing if advanced MRI scans can show brain changes in testicular cancer patients with low testosterone who are getting hormone therapy.

What this trial studies

This observational study evaluates the use of 7 Tesla magnetic resonance imaging (MRI) to observe structural changes in the brain of testicular cancer patients suffering from hypogonadism who are receiving androgen replacement therapy. Participants will undergo MRI scans at baseline and again after 12 months, alongside cognitive assessments and blood sample collection. The goal is to determine if 7T MRI can provide clearer images that reveal changes in brain architecture associated with hypogonadism and cancer treatment. This research may enhance understanding of the neurological impacts of low testosterone in this patient population.

Who should consider this trial

Good fit: Ideal candidates are males aged 18 and older diagnosed with testicular germ cell tumors and experiencing hypogonadism while on androgen replacement therapy.

Not a fit: Patients with a history of neuropsychiatric diseases or those who cannot undergo MRI due to contraindications will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic techniques for assessing brain health in testicular cancer patients undergoing hormone therapy.

How similar studies have performed: While the use of advanced MRI techniques is gaining traction, this specific application in testicular cancer patients with hypogonadism is relatively novel and has not been extensively tested.
