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 [...]
We have become very fortunate over the last 6 years because our arsenal of potential drugs to treat advanced, metastatic prostate cancer has grown. All of our new drugs extend life and most offer palliation of pain. As I have discussed in prior posts we are still in a quandary about how best to sequence [...]
We are in desperate need of validated biomarkers, which can serve as surrogates for survival. Currently, our doctors must make decisions about which drugs to use and how long to stay on these drugs without any scientific backup or consensus driven direction to their decisions. Our clinical trials for evaluating survival of potential new advanced [...]
In a recent publication it was suggested that radiographic progression-free survival (rPFS) in men with metastatic castration-resistant prostate cancer (mCRPC) was highly consistent and highly associated with overall survival. This reproducible quantitative find could have implications for the interim measurement of treatment response in future studies, according to Dr. Michael J. Morris of Memorial Sloan [...]
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 [...]
