@hm10 & @leann66...... I found out more info on the recent trial using a particular scan-type to determine if a treatment is working, as early as possible.
I went ahead and researched online to see if I could find more on this study, and there was much more specific information! This looks like a game changer in finding the best treatment for those with bone metastasis, much more quickly.
"The study’s lead investigator, Jennifer M. Specht, MD, a medical oncologist at the University of Washington and Fred Hutch Cancer Center, presented the results of the FEATURE trial (EA1183, NCT04316117) at the 2025 San Antonio Breast Cancer Symposium. Heather A. Jacene, MD, a nuclear medicine physician from Brigham and Women’s Hospital and Dana-Farber Cancer Institute, co-led the trial with Dr. Specht." It also said "This multi-center trial involved investigators and patients at 35 hospitals and cancer centers across the United States and in Ireland. It received support from the National Cancer Institute..." So it's not just at my cancer center.
