What this trial studies

This pilot study evaluates the effectiveness of FAZA PET/MRI scans in predicting therapy responses for patients with metastasized gastro-oesophageal cancer undergoing platinum-based chemotherapy. The study aims to identify intratumoral hypoxia, a feature associated with aggressive tumor behavior, which may help in predicting how well patients respond to treatment. By using a single arm design, all participants will receive the FAZA PET/MRI scan before and after their chemotherapy regimen. The goal is to establish a potential biomarker for therapy response in this patient population.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with de novo or secondary metastasized gastro-oesophageal adenocarcinoma.

Not a fit: Patients who are pregnant, breastfeeding, or have contraindications for MRI will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new method for predicting treatment responses in patients with advanced gastro-oesophageal cancer, potentially improving patient outcomes.

How similar studies have performed: While the use of imaging techniques in cancer treatment is established, the specific application of FAZA PET/MRI for this purpose is novel and has not been extensively tested in prior studies.
