An Independent Prognostic Tool For Men With Metastatic Castrate Resistant Prostate Cancer Taking The Newer Drugs

We have a number of newer hormone pathway drugs now available to treat men with metastatic castrate resistant prostate cancer (mCRPC). Researchers have shown that prostate specific antigen (PSA) response can be used as a pharmaco-dynamic end-point that may help identify men with early resistance to these new drugs. They found that there is clinical [...]

Surprise: High-Dose Testosterone Therapy Might Help Some Men with Advanced Prostate Cancer

There has been some surprising and unexpected news recently reported by John’s Hopkins Kimmel Cancer Center. Testosterone, which is believed to be a feeder of prostate cancer has been found to also suppress some advanced prostate cancers and also may reverse resistance the to the testosterone-blocking drugs (ADT) used to treat advanced prostate cancer. The [...]

Predicting Resistance to Enzalutamide and Abiraterone in Men with Metastatic Castration-Resistant Prostate Cancer (mCRPC).*

In yesterday's post I wrote about the possibility of looking for the presence of the splice variant ARV7 to determine if you would be resistant to enzalutamide (Xtandi).  Today I am going to expand on this issue and discuss an additional study that demonstrated that the presence of ARV7 in circulating tumor cells not only [...]

Understanding and Predicting Initial Resistance to Enzalutimide (Xtandi) by Evaluating the Presence of ARV7 *

I have written a lot about how we need more data about the many new drugs we have to treat men with advanced prostate cancer.  The many questions that continue to swirl around us pertain to the development of cross resistance (taking one drug causes another to not work) between these new drugs, knowing the [...]
