Prostate-specific membrane antigen in malignant brain tumors: vascular heterogeneity, imaging promise, and therapeutic challenges
Malignant brain tumors have high morbidity and poor prognosis. Prostate-specific membrane antigen (PSMA) has emerged as a promising vascular biomarker in this setting, particularly in gliomas and brain metastases. This review synthesizes current evidence on PSMA expression patterns, regulatory mechanisms, imaging appli...
