Prostate Cancer and Prostatic Diseases: From the Editor

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,

This compelling study revisits the concept of neoadjuvant adjuvant deprivation therapy (ADT) prior to radical prostatectomy. A small series of randomized clinical trials (RCTs) performed almost 20 years ago failed to demonstrate substantial benefits in patients with localized prostate cancer who received ADT before surgery. Based on these data, the American Urological Association and the European Association of Urology recommend against ADT prior to prostatectomy outside the setting of a clinical trial.

Molecular risk tools are being increasingly utilized in men with localized prostate cancer to help in clinical decision making around the need for surgery or radiation vs. active surveillance, and for the need for salvage radiation after surgery.  The Decipher Genomic Classifier has recently been demonstrated to predict distant metastases in men undergoing radical prostatectomy, using biopsy or surgical tissue, and may provide a greater level of prognostic discrimination than current NCCN or CAPRA risk groups.

Urethral strictures do not tend to be at the forefront of most clinicians’ minds when considering the adverse effects of radiotherapy for prostate cancer. Quite correctly, the first considerations would be for those associated with any collateral damage to the rectum or bladder. But all urologists are well aware of radiation-related urethral strictures because the great majority would have these patients in their clinical workload. They are ‘heavy’ patients in that they need a lot of counseling and often require a lot of work to ‘manage’ their disease.  It is often a case of where a few patients as such can

Race, family history, and age.  Those are the three classic risk factors for prostate cancer that are etched in stone in every textbook and course taught. While absolutely true, the challenge is that none of these are modifiable.  We can’t change our race.  We can’t grow younger and as much as some of us would like, we can’t change our parents. As such, we are stuck.  Our risk is our risk.  Or is it?  Are there modifiable risk factors for prostate cancer? It is now clear that obesity and smoking are modifiable risk factors for fatal prostate cancer. While avoiding obesity and not smoking sound like overall good advice, is there more specific advice we can give to our patients or to men at risk who don’t want to become patients in the first place.
