Triple-Tracer PET Imaging Reveals High Intrapatient Heterogeneity in Metastatic Prostate Cancer
- A multi-center study using triple-tracer PET imaging (18F-FDG, 68Ga-PSMA, 68Ga-DOTATATE) reveals high intrapatient intermetastatic heterogeneity (IIH) in mCRPC patients.
- IIH was observed in 82.7% of patients, with 45.9% showing at least one 18F-FDG-positive/68Ga-PSMA-negative lesion, suggesting potential neuroendocrine differentiation.
- Patients with IIH exhibited significantly shorter overall survival (9.5 months) compared to those without IIH, highlighting the clinical impact of tumor heterogeneity.
- Based on imaging criteria, 53.1% of participants were eligible for PSMA-targeted radiopharmaceutical therapy, emphasizing the role of PET imaging in treatment stratification.
