From the Desk of the Editor: Non-Metastatic Metastases and Other Confusing Findings from the PROSPER and SPARTAN Trials

Last month we saw the final published data from the PROSPER study1, and coupled with the earlier published SPARTAN study2, we now have two complete and large phase III studies detailing the clinical activity of androgen-receptor inhibitors, enzalutamide and apalutamide in so-called “non-metastatic” castrate-resistant prostate cancer (nmCRPC) patients. I am impressed with the results of these two studies; both demonstrated a robust clinical effect in delaying or preventing the development of metastases in this patient population that I believe is clinically beneficial in patients who are likely to live long enough to die from metastatic prostate cancer.  While I appreciate the FDA approval of these agents to treat this patient population, I don’t like this term non-metastatic CRPC.
