New scan aims to uncover hidden breast cancer in early stage patients
NCT ID NCT06540872
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new imaging method called FAPI-PET/MRI to see if it can detect hidden invasive breast cancer in 30 people diagnosed with ductal carcinoma in situ (DCIS), a common pre-stage of breast cancer. Participants receive a weakly radioactive drug and lie in a scanner for about 45 minutes. The results will be compared to tissue samples from surgery to see how accurate the scan is.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Newly diagnosed DCIS with extent in mammography, MRI or ultrasound suspected to range \> 4 cm * Planned DCIS resection (breast conserving or mastectomy) as per guideline recommendation * Written informed consent * For women of child bearing potential: confirmed menstrual period (if applicable) and a negative highly sensitive urine or serum pregnancy test * Women of childbearing potential (WOCBP) and male patients with partners of childbearing/reproductive potential must agree to use highly effective contraception (Pearl index \< 1) when sexually active. This applies for the time period between signing of the informed consent form up to the final trial visit. Exclusion Criteria: * Contraindications for MRI (specific metallic implants, severe claustrophobia, history of anaphylaxis following MRI contrast agent application) * GFR \< 30 mL/(min∙1.73 m²) * Current pregnancy or within last 8 weeks before begin of study participation * Current nursing or within last 8 weeks before begin of study participation * Inability to understand the nature, risks, and benefits of the study * History of diagnosis of ipsilateral invasive breast cancer * Concurrent diagnosis of contralateral invasive cancer, if not curatively treated by surgery \> 1 year ago * Known hypersensitivity to the active substance or to any of the excipients of the Investigational Medicinal Product
