New Full-Body scan could replace biopsies for breast cancer immunotherapy
NCT ID NCT05742269
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a special PET/CT scan that uses a radioactive tracer to see PD-L1 (a protein targeted by immunotherapy) throughout the body. The goal was to see if this scan could better identify which patients with metastatic triple-negative breast cancer would benefit from immunotherapy, compared to the standard biopsy method. Only 3 patients were enrolled before the study was terminated, so the findings are very limited.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
89Zr-atezolizumab (a radioactive tracer for PET/CT scans)
What this could lead to
If successful, this imaging method could help doctors choose the right immunotherapy for breast cancer patients without needing repeated biopsies.
What could go wrong
This was a very small, early study (only 3 participants planned) and was terminated early, so results are limited. The scan may not reliably predict who benefits from treatment.
