About
Andrew Ryan is a leading figure in prostate cancer research, with a primary focus on the clinical application of prostate-specific membrane antigen (PSMA) as both a diagnostic and therapeutic target. His work bridges the critical gap between advanced molecular imaging and traditional histopathology. In his highly cited study, "Prostate‐specific membrane antigen (PSMA)‐PET‐avid prostate cancers show stronger PSMA immunohistochemistry staining on biopsy cores," Ryan provided foundational evidence that the intensity of PSMA expression seen on PET scans directly correlates with the degree of PSMA protein present in tissue samples. This validation is crucial for clinicians, as it confirms that PSMA-PET avidity is a reliable, non-invasive surrogate for the molecular characteristics of a tumor. By correlating imaging findings with the long-established tool of immunohistochemistry, Ryan’s contributions help refine patient selection for PSMA-targeted radioligand therapy and improve the accuracy of biopsy interpretation. His work continues to shape how prostate cancer is diagnosed and staged, ensuring that advanced imaging technologies are grounded in robust pathological evidence.
