Androgens and prostate cancer: are the descriptors valid?

The term androgen-independent cancer has now become a misnomer. Given that the androgen receptor can be activated by even low androgen concentrations or via protein modifications or other protein-protein interactions, a growing prostate cancer has the chance of assuming an androgen depletion-independent state, without necessarily bypassing the androgen signaling processes. It is thus suggested that "androgen-independent (AI)" cancer should be more accurately termed "androgen depletion-independent (ADI)" cancer.
