Androgen-responsive POSLUMA-guided Intra-prostatic Boost (ARPEGGIO)
Martin T. King, MD, PhD
Summary
This research study is for men with intermediate- or high-risk prostate cancer who are planning to receive hormone therapy and radiation treatment. The purpose of the study is to see whether a special type of diagnostic imaging done during hormone therapy can help doctors more accurately target remaining cancer with radiation, while avoiding areas that may no longer need extra treatment. All participants will receive standard hormone therapy and radiation therapy, along with three imaging scans, over a six-month period. The information gained from this study may help make prostate cancer radiation treatment more precise and reduce side effects for future patients.
Description
Prostate cancer is commonly treated with a combination of hormone therapy and radiation therapy. Hormone therapy, or androgen deprivation therapy (ADT), lowers testosterone levels and often shrinks or weakens prostate cancer before radiation begins. However, after hormone therapy starts, it can become harder for doctors to tell exactly where active cancer remains inside the prostate using standard imaging (typically an MRI). This study is being conducted to determine whether a newer imaging test can better identify which parts of the cancer are still active and may benefit from more focused ra…
