One of the hot topics in the prostate cancer community is the value of detecting AR-V7 tumor cells circulating in the blood. AR-V7 tumor cells in the blood predicts response or failure of treatment with enzalutamide (Xtandi) or abiraterone (Zytiga). A recent study found that men who have AR-V7 circulating tumor cells in their blood will not [...]
Screening for early cancer detection may reduce the rate of related metastatic disease, but not always. In a published study in the New England Journal of Medicine, researchers evaluated the incidence of men having a diagnosis of advanced, metastatic prostate cancer at the initial prostate cancer diagnosis. The researchers data from the Surveillance, Epidemiology, and [...]
In a press release issued yesterday, Genomic Health Inc. announced topline results from their clinical validation study of its biopsy-based Oncotype DX® Genomic Prostate Score™ (GPS). The study met its primary endpoint by demonstrating that Oncotype DX® test is a strong predictor for the development of metastasis and also prostate cancer death in men with early-stage prostate [...]
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 often refer to prostate cancer as a family affair, or rather being passed on from father to son, etc. This is only partially true because there is still more prostate cancer diagnosed in men without any family history. For those cancers that are passed on from one family member to another it is important [...]
