Three cases of nonmetastatic prostate cancer treated successfully with primary intermittent androgen deprivation therapy over 10 years.

IAD is not a standard therapy for patients with nonmetastatic prostate cancer. However, based on our experience, we suggest that IAD is one of useful therapeutic tools under certain patients' condition.
