PSMA Expression in Cancer
Bladder Cancer
Compared with normal urothelium, bladder cancer tissue expresses very high levels of PSMA. PSMA is an emerging biomarker for diagnosis and therapy of transitional cell carcinoma.4
Breast Cancer
Up to 60% of patients with breast cancer expressed PSMA-positive endothelia with the FOLH1 gene corresponding with invasive breast cancer. PSMA expression correlated with tumor grade and NST subtype, especially for patients with HER2-positive status. PSMA levels approached almost five times that of other tumors in triple-negative carcinoma cases.5
Colorectal Cancer
Approximately 75% of all colorectal cancer cases express PSMA positivity. Furthermore, PSMA expression was strongly associated with vascular invasion and distant metastasis.6
