Beskrivelse
Inclusion Criteria:
Age 18 years or older Able to understand and provide written informed consent
Diagnosis of a breast cancer or other tumor known or suspected to express GRPR, including:
ER-positive/HER2-negative breast cancer Invasive lobular breast cancer Head and neck squamous cell carcinoma Small-cell lung cancer Ovarian cancer Prostate cancer with biochemical recurrence and a negative PSMA PET/CT Metastatic pancreatic cancer after pancreatic surgery Other tumor with GRPR expression demonstrated on histopathology ECOG performance status 0-3 Under the care of a referring physician Able to tolerate PET/CT imaging, including lying supine for up to 30 minutes with arms above the head and intravenous cannulation
Exclusion Criteria:
Tumor type known in the literature not to express GRPR, unless patient-specific tissue demonstrates GRPR expression Medically unstable condition, including acute cardiac or respiratory distress or hypotension Weight exceeding PET/CT table limit of 200 kg or inability to fit within the 70-cm PET/CT bore Unmanageable claustrophobia Known allergic or hypersensitivity reaction to a prior GRPR-targeting radioligand such as ⁶⁸Ga-RM2 or bombesin analogues Pregnancy Lactation For individuals of childbearing potential, inability to document a negative pregnancy test before tracer administration

Intervention / Behandling |
|---|---|
|
Eksperimentel: [⁶⁸Ga]-GRPR PET/CT
Participants with breast cancer or other selected GRPR-expressing malignancies will receive a single intravenous administration of approximately 170 MBq ±20% of [⁶⁸Ga]-LY4257529, followed by PET/CT imaging approximately 50-70 minutes after injection.
All participants undergo the same imaging intervention.
|
[⁶⁸Ga]-LY4257529 is an investigational gastrin-releasing peptide receptor (GRPR)-targeted PET radiopharmaceutical.
Participants will receive approximately 170 MBq ±20% (4.6 mCi ±20%) intravenously.
PET/CT imaging will begin approximately 50-70 minutes after administration to evaluate GRPR-targeted tumor uptake and distribution.

Tidsramme |
|---|---|---|
|
Per-Patient GRPR PET/CT Detection Rate
Tidsramme: After the PET/CT imaging is completed
|
Proportion of participants with at least one GRPR-positive lesion on [⁶⁸Ga]-LY4257529 PET/CT.
Detection rate will be calculated as the number of participants with at least one GRPR-positive lesion divided by the total number of participants in the relevant cancer cohort.
