A PET scan to find hidden spread in slow-growing breast cancer
This trial is testing a special PET scan (18F-FES PET/CT) to see if it can find distant cancer spread in women with a slow-growing, estrogen receptor-positive, stage III breast cancer. The goal is to find out whether this imaging test can detect hidden metastases better than standard scans.
SeoulAges 19 years+ - NCT05968677Recruiting
Amino acids and flavonoids to reduce chemotherapy side effects
This trial tests whether a specific nutrition supplement (amino acids and flavonoids) can lessen chemotherapy side effects, support nutrition, and improve quality of life in people with non-metastatic breast cancer.
