Prostate Cancer and Prostatic Diseases: From the Editor

Androgen deprivation therapy (ADT) is the mainstay of systemic therapy for men with metastatic or recurrent hormone-sensitive prostate cancer (mHSPC), as well as localized and PSA recurrent prostate cancer when radiation is indicated for higher risk disease. ADT is also continued indefinitely in men with mCRPC, and thus many men with aggressive forms of prostate cancer will be treated with years of ADT and face the cumulative risks of low testosterone.

Cholesterol is a key building block of cells. It provides crucial support to cell membranes allowing signaling between the inside and outside of cells. Cholesterol makes up ~ 1/3 of the cell membrane. Also, cholesterol is the precursor for many hormones – including testosterone. Without cholesterol, life as we know it could not exist. However, there is such a thing as too much of a good thing. Specifically, high serum cholesterol levels have been linked with numerous conditions such as cardiovascular disease, stroke, and many cancers.

This comprehensive review summarizes important clinical concepts in the rapidly advancing field of positron emission tomography/computed tomography (PET/CT) for prostate cancer. The authors reviewed 18F-NaF-, choline-, fluciclovine- and prostate-specific membrane antigen (PSMA)-based modalities in primary disease staging and assessment of biochemical recurrence. The most thoroughly studied modality to date is choline PET/CT.

Prostate cancer is known to be an immune evasive tumor, often coexisting with areas of inflammation in the primary site, but without over-expression of the traditional PD-1/PD-L1 immune checkpoint, unlike many other cancer subtypes.  While certain prostate cancer subsets like microsatellite high (MSI high) and CDK12 deleted disease may respond well to single agent PD-1 pathway inhibitors, in most (>90%) of prostateadenocarcinomas, other immunosuppressive molecules and pathways are likely to be of greater importance and have yet to be adequately targeted.  Here is where B7-H3 may be relevant.

The proof of concept for the utility of urinary biomarkers to predict biopsy outcome was published in 2003 by Hessels et al, which subsequently led to the launch of the PCA3 test in 2007.  The test was mostly used for repeat biopsy decisions, to which also the FDA approval in 2012 was confined. The potential utility in active surveillance settings was suggested by many and in their recent paper Tosoain et al study the value of a first PCA3 outcome (fPCA3) and a subsequent PCA3 test (sPCA3) to predict Grade Reclassification (GR) in men on active surveillance.

A large number of studies on ⁶⁸Ga PSMA PET/CT are coming out of Australia due to the ready access to this technology.  To give some background, PET/CT imaging has long been registered with the Australian Therapeutic Goods Administration (TGA) and with this has come the approval to use any radionuclide tracer.  With it being unnecessary to apply for additional registration to use new tracers, this has allowed uptake of 68Ga PSMA PET/CT into routine clinical practice throughout Australia and to the extent that it is rapidly replacing conventional radionuclide bone scans and CT scan of the abdomen and pelvis as imaging for the staging of prostate cancer.

Obesity is all around us.  Over 30% of all Americans are obese. We know obesity is linked with many medical problems – heart disease, diabetes, hypertension, and of course cancer. Indeed, over a dozen different cancers have been linked with obesity. In regards to prostate cancer, while obesity may lower the risk of low-grade indolent cancer, it unequivocally increases the risk of high-grade aggressive disease. Many explanations have been put forward: alterations in insulin levels, changes in sex steroid hormone levels, higher cholesterol,
