New study aims to spot hidden cancer spread in lobular breast cancer
NCT ID NCT07635654
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will test whether whole-body MRI scans and blood tests for tumor DNA can better detect cancer progression in a type of breast cancer that is often missed by standard scans. Researchers will follow 43 people with metastatic invasive lobular carcinoma for up to 30 months, comparing the new methods with usual care. The goal is to see if these tools help doctors make better treatment decisions and improve patient access to trials.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to better monitoring of metastatic lobular breast cancer, helping doctors detect progression earlier and allowing more patients to qualify for clinical trials.
- What could go wrong
- This is a small, early-stage observational study (43 people) that is not yet recruiting. It tests imaging and blood tests, not a treatment, so it will not directly improve outcomes. Results may not apply to all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Voluntary written informed consent of the participant or their legally authorized representative has been obtained prior to any screening procedures 2. At least 18 years of age at the time of signing the Informed Consent Form (ICF) 3. ECOG from 0 to 2 4. Patient with stage IV ILC, either de novo or after prior (curative) treatment for early ILC. Histological subtype confirmed on primary tumor or on metastatic tissue. Patients that are diagnosed with stage IV breast cancer that have a mixed ILC/IBC-NST histology of the primary tumor (mixed histology within the same primary lesion) will also be able to participate and will be analyzed in an exploratory cohort. 5. Confirmation of hormone receptor positive (HR+)/HER2- disease either on new biopsy or archival tissue (e.g. primary tumor) 6. Multifocal or bilateral disease is allowed if all evaluated foci present with HR+/HER2- ILC 7. Starting first line of treatment for metastatic ILC Exclusion Criteria: 1. Presence of a contraindication to perform WB-DWI/MRI 2. Presence of severe claustrophobia 3. Presence of a contraindication to use IV contrast for CT or PET/CT (e.g. allergy, severe renal failure) in case a non-contrast PET/CT cannot be performed 4. Patients considered to have oligometastatic disease who are expected to undergo locoregional treatment 5. Presence of other malignancies in recent medical history (\<5 years) 6. Female who is pregnant, breast-feeding or intends to become pregnant or is of child-bearing potential and not using an adequate, highly effective contraceptive 7. Adults who are the subject of a legal protection measure or who are unable to express their consent.
