Men who are initially diagnosed with intermediate-risk prostate cancer may or may not be good candidates for Active Surveillance. This excellent article begins to provide a basis for making that determination. You can read the article by clicking HERE.
Moderately hypofractionated IMRT (radiation therapy delivered in 20 to 26 treatments instead of the conventional 40-44 treatments) has received strong endorsement from all of the major US organizations of physicians who treat prostate cancer. Read more about this significant new guideline here.
Scientists at Cedars-Sinai have discovered how prostate cancer can sometimes withstand and outwit a standard hormone therapy, causing the cancer to spread. Their findings also point to a simple blood test that may help doctors predict when this type of hormone therapy resistance will occur. Learn more about these interesting findings by clicking HERE.
So you’ve had your PSA test, and it came back high. Your doctor did a DRE and ran a few more tests, and assures you that prostate cancer is very unlikely. Still, you’re worried. What are some other causes of a high PSA?

Reported in Urology Times:
For urologists and radiation oncologists alike, when treating prostate cancer, one recurring theme is “protect the rectum.” As surgeons, we learn meticulous techniques to avoid rectal injuries, and our radiation colleagues have long strategized on how to optimally deliver the maximum dose of tolerable radiation while minimizing radiation exposure to “organs at risk” such as the bladder, rectum, urethra, and penile bulb. In this era of dose escalation and hypofractionation, rectal toxicity is of paramount consideration.
In this article, we discuss one particular new product and how it may herald a significant change in the landscape of radiation therapy for prostate cancer.

Enzalutamide (XTANDI) is a prescription medicine used to treat men with prostate cancer that no longer responds to a medical or surgical treatment that lowers testosterone. XTANDI is now approved to treat men with prostate cancer that no longer responds to treatment that lowers testosterone and has not spread to other parts of the body. This is also known as non-metastatic castration-resistant prostate cancer (CRPC).
This web page, published by the National Cancer Institute, lists the clinical trials using Enzalutamide. Click here to view the article.
Once a man is castrate resistant and moves on a second line hormone therapy drug like Zytiga or Xtandi (aka AR inhibitors) it is inevitable that the Zytiga or Xtandi will also become ineffective.
When this happens, the question that comes is what should be the next treatment? Generally, the options currently available are either to move to the drug not initially used ( Zytiga if Xtandi was first used or Xtandi if Zytiga was used) or instead to use taxane chemotherapy (Taxotere aka docetaxel).
Knowing which of these two options is best has been nothing but guesswork. But, things are improving. There is an investigational test that detects the expression of a protein called AR-V7 in the nuclei of circulating tumor cells taken from a vial of blood cells (liquid biopsy). This test can help guide this decision.
A recent study (published in JAMA Oncology) evaluating this test has shown that a blood test can detect the protein called AR-V7 in circulating tumor cells and that the presence of this protein accurately predicts how well certain men will respond to AR inhibitors (Zytiga and Xtandi).

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.

It has just been recently announced that the U.S. Food and Drug Administration (FDA) has approved a generic version of Zytiga, the new drug’s name is Yonsa. It is a novel formulation of abiraterone acetate that needs to be used in combination with methylprednisolone for the treatment of men with metastatic castration-resistant prostate cancer (mCRPC).
