Using PET/MRI and AI to predict complete tumor response in HER2‑positive breast cancer

Official title: Multiparametric 18F-FDG PET/MRI for Assessment and Prediction of Locoregional Therapy Response in HER2-positive Breast Cancer Patients Using Artificial Intelligence

Run by Heinrich-Heine University, Duesseldorf · NCT06708910 · Data updated 2026-11-12

This study will test whether PET/MRI scans combined with artificial intelligence can tell which women with HER2‑positive breast cancer have no remaining tumor after neoadjuvant therapy.

Is this trial a fit for you?

Likely a good fit

Adult (≥18) women with confirmed HER2‑positive breast cancer who are willing to undergo PET/MRI scans, have agreed to neoadjuvant systemic therapy, and can give informed consent are ideal candidates.

Probably not a fit

Patients who are pregnant or breastfeeding, have severe renal insufficiency, have contraindications to MRI, have recent or synchronous other cancers, or have distant metastases are unlikely to benefit or be eligible.

What this trial studies

This observational study collects 18F‑FDG PET/MRI scans from women with HER2‑positive breast cancer who are planned for or receiving neoadjuvant systemic therapy and compares imaging-based AI predictions to surgical pathology. The primary co-endpoints are sensitivity and specificity for identifying pathological complete response (pCR; yT0 yN0). Secondary endpoints include accuracy and separate performance measures for primary-tumor pCR (yT0) and overall pCR. No investigational drugs are given; the study focuses on image acquisition, AI analysis, and correlation with standard pathological results.

Why it matters

Potential benefit: If successful, the approach could help identify patients with complete response noninvasively and support more personalized surgical or treatment planning.

How similar studies have gone: Previous smaller studies combining PET/MRI and machine‑learning methods have produced promising but not yet definitive results, so the approach remains emerging.
