Prostate cancer tends to metastasize to bones as opposed to soft tissue and other organs. We have no idea why it does have a preference for bone, but it does. Developing bone metastases in prostrate cancer is a very strong negative prognostic indicator. Prostate cancer’s tendency to favor bone over soft tissue causes significant morbidity [...]
Again and again I have mentioned the huge need we have for the development of reliable bio-markers. Reliable bio-markers will allow us to know which men will respond positively to a treatment (also those who will not) and when a treatment is still effective (also when it no longer is effective). These biomarkers really don’t [...]
Researchers at Queen’s University in Belfast along with the Belfast Trust are conducting a clinical trial evaluating the combination of two radiotherapy treatments, Radium 223 and Pelvic Radiation using Volumetric Modulated Arc Therapy (VMAT) in men with bone positive advanced prostate cancer. The trial, being called ADRRAD trial, involves combining androgen deprivation therapy (ADT) along [...]
Not often discussed, but a valuable measure of prostate cancer bone activity is serum (in the blood) alkaline phosphatase. It is a normal enzyme produced naturally by the body. Everyone produces some of this enzyme regardless of his or her state of health, gender, or age. The tissues that produce the most alkaline phosphatase are the [...]
The current standard hormone therapy (ADT) for men with advanced prostate cancer is a class of drugs called Luteinising hormone-releasing hormone agonists (LHRHa). These drugs reduce serum oestradiol as well as testosterone, causing bone mineral density (BMD) loss as a side effect of the ADT. Using transdermal (skin patches) oestradiol is a potential alternative to [...]
Radium-223 (Xofigo) is a drug for men with castrate resistant metastatic prostate cancer (mCRCP) who have multiple bone metastases. Radium-223 selectively targets bone metastases by mimicking calcium, which is attracted to the bone, especially to the fast growing areas of the tumor in the bone. It emits an alpha-emitting dose of radiation, which is mostly contained [...]
Researchers are now beginning to understand which men with castration-resistant prostate cancer (CRPC) might be helped by radium-223 (Xofigo), and for which men Xofigo will be a waste of time and money, and possibly cause harm. They have found that baseline ECOG performance status, alkaline phosphatase (ALP), hemoglobin (Hb) levels, and the concomitant use of abiraterone acetate (Zytiga) [...]
As I have said before, the next big step in the clinical care of men with prostate cancer will be in not in the development of a new drug, but in our growing knowledge of how to sequence and combine our new drugs. Today’s post provides just one example of this new type of breakthrough [...]
Xgeva, also known as denosumab, is an injectable medication (injected once a month subcutaneously under the skin in the doctor’s office) that is used to prevent bone fractures and spinal cord compression caused by bone metastases in breast and prostate cancer survivors. Solid tumors in the bone, which is a common site for individuals with [...]
The development of bone metastases is often been viewed as having significant negative implications for long term survival in men with metastatic castrate resistant prostate cancer (mCRPC). It is generally believed that bone metastases prognosticates a negative impact on both their quality of life and on survival. Contradicting this commonly held belief has been some [...]
