How advanced prostate cancer becomes resistant to androgen-deprivation therapy

For the past 70 years the treatment of choice for advanced, metastatic prostate cancer has been androgen-deprivation therapy.

While such therapy buys time for patients, it is not a cure, as inevitably the cancer becomes resistant to the androgen deprivation and continues to grow.
