Molecular Profiling of Prostate Cancer Lesions With MRI-PSMA PET Discordance

Magnetic Resonance Imaging and PSMA-PET are currently the most sensitive imaging modalities for prostate cancer, yet they do not always provide concordant results. Discordant lesions, those detected by one modality but not the other, represent a significant clinical challenge, as their biological nature and implications remain poorly understood. A molecular characterization of these lesions may clarify whether they correspond to indolent clones missed due to imaging limitations, aggressive subclones with distinct molecular features, or biologically different disease entities. We aim to investigate prostate cancer lesions that are discordant between MRI and PSMA-PET, with the specific objective of elucidating their molecular characteristics and clinical implications. Molecular omic analyses will be performed on existing biobank samples from patients enrolled at our institution who have already provided informed consent for research use. This resource provides access to high-quality biospecimens linked with imaging data, enabling a comprehensive evaluation of MRI-PSMA PET discordant prostate cancer lesions.
