“By academic freedom, I understand the right to search for truth and to publish and teach what one holds to be true.  This right implies also a duty: one must not conceal any part of what one has recognized to be true.  It is evident that any restriction on academic freedom acts in such a way as to hamper the dissemination of knowledge among the people and thereby impedes national judgment and action.” -Albert Einstein

Prostate-specific membrane antigen (PSMA) is expressed 100 to 1,000 times more highly in prostatic adenocarcinoma than in benign prostate tissue, particularly in the setting of androgen deprivation.1 Around the world, we are seeing the rapid adoption of PSMA PET-CT/MRI, which is able to detect metastatic disease that is inapparent on conventional imaging (CT and bone scintigraphy).

Patients whose metastatic castration-resistant prostate cancer (mCRPC) has progressed on taxane chemotherapy and second-generation anti-androgen agents have few alternatives to palliative care. However, radiolabeled prostate-specific membrane antigen (PSMA) conjugates are now in latephase studies. In this article, I discuss theranostics, the phase 3 VISION trial, and the questions we will need to consider when PSMA-targeted radioligand therapies become available for use in our advanced prostate cancer clinics.

Experts at Harvard Business School first coined the term disruptive innovation to describe how small, poorly resourced companies could successfully challenge larger ones.1 More than two decades later, this concept is central in medicine, where innovations in everything from proteomics and wearables to electronic health records and health economics are upending our status quo.2,41

Prostate cancer [PCa] affects 1 man in 7 in the United States, making this the most commonly diagnosed non-cutaneous cancer in males.  Although an ever-increasing number of treatment options exist, an estimated 26,100 men will still die of the disease in the US in 2016, generally after primary local and systemic treatments for prostate cancer have failed.

An accurate assessment of the extent of disease is critical to the care of patients with cancer, across the natural history of disease including initial evaluation, following local treatment, and assessing response to systemic therapy. Thus, improvements in radiographic imaging may revolutionize

Prostate-specific membrane antigen (PSMA) is a type II transmembrane glycoprotein which functions as a zinc metalloenzyme and is found on prostatic epithelium. In normal prostate tissue, PSMA expression and localization focuses on the cytoplasm and apical side of the epithelium surrounding prostatic ducts.

The purpose of this document is to describe the appropriate use of imaging in the diagnostic evaluation of patients with BCR after definitive primary treatment. The imaging modalities that were considered included CT, bone scan, and the U.S. Food and Drug Administration (FDA)–approved PET radiotracers that track malignancy-induced lipogenesis (11C-choline) and amino acid metabolism (18F-fluciclovine).

Conference Highlights from Recent Conference Coverage
Presented by Alberto Bossi, MD
Dr. Alberto Bossi discussed radiotherapy after radical prostatectomy in the PSMA-PET era. Adjuvant radiotherapy is defined as immediate postoperative radiation in the case of extraprostatic extension, positive margins, seminal vesicle infiltration, high Gleason score, or pN+ disease. Salvage radiotherapy is defined as a wait-and-see policy in that radiation is only given in the case of a rising postoperative PSA.

The EAU 2021 Annual Meeting included a presentation by Johann De Bono discussing the VISION trial, a phase 3 study of 177Lu-PSMA-617 in patients with mCRPC. As PSMA is highly expressed in prostate cancer and mCRPC lesions, the combination of PSMA-617 with the beta-emitter lutetium allows for the targeted delivery of ß-particle radiation to PSMA-expressing cells and the surrounding microenvironment.
Presented by Mary-Ellen Taplin, MD

There are currently significant imaging deficiencies for men with prostate cancer (Figure 1), with the hope that PSMA imaging-based modalities will address a significant gap in this field. Prostate-specific membrane antigen PSMA is a transmembrane glycoprotein with folate hydrolase activity.
Presented by Michael J. Morris, MD
Men with biochemically recurrent prostate cancer after definitive local therapy currently have limited imaging modalities in the United States which are sensitive or specific enough to detect tumor recurrence. PSMA PET scans can improve on this detection by detecting cells expressing PSMA protein on their cell surface.
