A case of spinal and bulbar muscular atrophy with high-stage and high-gleason score prostate cancer responded to maximal androgen blockade therapy

Abstract

Spinal and bulbar muscular atrophy is a hereditary motor neuron disease caused by the expansion of CAG triplets in the androgen receptor. Because the length of CAG repeat is inversely related with androgen receptor function, patients with a longer CAG repeat are expected to have a lower incidence of prostate cancer. Here, we report an extremely rare case of highstage prostate cancer in a patient with spinal and bulbar muscular atrophy, which responded to maximal androgen blockade therapy. © American Society of Andrology.
