Updates on Clinical/Research Activities in Prostate Cancer at Stanford University

Dr. Andrei Iagaru, Professor of Radiology and Chief of the Division of Nuclear Medicine and Molecular Imaging at Stanford presented to our group about Nuclear Medicine at Stanford University and Updates on Clinical/Research Activities in Prostate Cancer on March 7, 2019.

Overview of PET/CT Imaging in Recurrent Prostate Cancer – Current and Emerging Techniques

From Dr. Fabio’s blog post:

Over the last few years, we have seen tremendous activity in the area of molecular imaging for prostate cancer. Just about every day we have colleagues asking about the various PET/CT imaging tests – what is available?  How do they compare?  What are the parameters for successful imaging?

We are proud to have contributed to this body of knowledge. Our work regarding C11-Acetate PET/CT imaging in the recurrent PCa setting with relationship to PSA kinetics has been recently published – representing the largest single-site evaluation of a molecular imaging agent. A link to the publication and brief overview of PET/CT Imaging for Prostate Cancer follow for your review.  We hope you find this review useful.

Prostate cancer–specific PET radiotracers: A review on the clinical utility in recurrent disease

Prostate cancer–specific positron emission tomography (pcPET) has been shown to detect sites of disease recurrence at serum prostate-specific antigen (PSA) levels that are lower than those levels detected by conventional imaging. Commonly used pcPET radiotracers in the setting of biochemical recurrence are reviewed including carbon 11/fludeoxyglucose 18 (F-18) choline, gallium 68/F-18 prostate-specific membrane antigen (PSMA), and F-18 fluciclovine.

Note that this article mentions C-11 acetate briefly but does not cover it. Phoenix Molecular Imaging is not shown on the map of imaging centers.  Also, the study does not examine the significance of PSA doubling time, whereas it has been reported that short doubling time enhances detection with C11-Acetate even at very low PSA.

Triple Hormonal Blockade (ADT3): A Patient’s Perspective

Opinion Article by Charles Maack

The information in this article is a lengthy read, but for men moved to androgen deprivation therapy the information is extremely important to be aware since everything explained may be involved in their well-being.

Triple-hormonal blockade/androgen deprivation therapy (ADT3) includes the prescribing of:

  1. a LHRH/GnRH agonist or antagonist to shut down testicular testosterone production
  2. an antiandrogen to block testosterone access to the cancer cell nucleus
  3. a 5Alpha Reductase (5AR) inhibitor to prevent any testosterone that might access the cancer cell nucleus from converting to dihydrotestosterone/DHT

More Than One Prostate Cancer in a Single Prostate?

As many as 40% of newly diagnosed PCa patients have unifocal disease, that is, just one focus of cancer. But that still leaves 60-80% of patients with multifocal PCa. Without evidence to the contrary, multiple foci in the same gland were thought to be biologically homogeneous, that is, identical to each other.

Then, along came the tools to analyze PCa at the molecular level, bringing new knowledge of the biology of PCa.

FDA Approves Enzalutamide (Xtandi) for the treatment of non-metastatic castration-resistant prostate cancer (non-metastatic CRPC)

The U.S. Food and Drug Administration (FDA) approved a new use for enzalutamide (Xtandi) for the treatment of non-metastatic castration-resistant prostate cancer (non-metastatic CRPC). Enzalutamide was previously approved only for patients with metastatic CRPC. Prior to this past February – when the FDA also approved apalutamide (Erleada) for non-metastatic CRPC – there were no FDA-approved treatments for these men.
