Predicting Esophageal Cancer Borders Using PET-Imaging

This study examines whether a special type of PET scan using FAPI imaging can more precisely map the borders of esophageal cancer before surgery. Knowing exactly where a tumor ends could help surgeons remove it more completely. **You may be eligible if...** - You are 18 or older - You have been diagnosed with esophageal cancer (adenocarcinoma or squamous cell carcinoma) confirmed by biopsy - Surgery is planned as part of your treatment - You are in good general health (ECOG 0 or 1) **You may NOT be eligible if...** - You have had prior radiation therapy in the tumor area - You had another cancer diagnosis within the past 5 years - Surgery is not possible for medical or technical reasons - Your cancer has already spread to distant organs Talk to your doctor to see if this trial is right for you.
