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 [...]
A late-stage clinical trial designed to see if Xtandi in addition to Zytiga along with a steroid worked any better than either of these drugs separately (combining them v sequencing them) in men with advanced prostate cancer whose disease had worsened it was concluded that the combination was not superior to the individual drugs.

They found that there is clinical [...]
