New model predicts prostate cancer treatment response using PET scans
NCT ID NCT07428642
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 168 men with metastatic hormone-sensitive prostate cancer to see if a model using PSMA-PET scans and routine medical information could predict how well they would respond to standard first-line treatment. The goal was to help doctors better understand which patients are likely to have a strong early response, without any extra tests or procedures. The findings could support more personalized follow-up and treatment planning.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Male patients diagnosed with metastatic hormone-sensitive prostate cancer (mHSPC). Distant metastasis confirmed by conventional imaging and/or PSMA PET/CT. Received first-line standard therapy based on androgen deprivation therapy (ADT) with an androgen receptor signaling inhibitor (ARSI), with or without docetaxel, as part of routine clinical care. Baseline PSMA PET/CT performed prior to initiation of first-line therapy. Availability of required baseline clinical data and PSA follow-up data. Exclusion Criteria: * History of or concurrent other primary malignancies. Non-adenocarcinoma prostate cancer histology (e.g., neuroendocrine tumors). Received prostate cancer therapies not consistent with the protocol-defined first-line setting around diagnosis (e.g., surgery, radiotherapy, chemotherapy other than protocol-defined docetaxel, targeted therapy, immunotherapy). Follow-up duration \< 3 months after treatment initiation.
