NCT ID NCT07316439

First seen Jan 08, 2026

Summary

This study looked at 197 breast cancer patients whose cancer had spread. It compared those whose tumors changed from hormone-sensitive (ER-positive) to hormone-insensitive (ER-negative) with those who had triple-negative breast cancer from the start. Using a special PET scan, researchers tracked how these changes affected survival and treatment response.
