The disagreement in this situation is between continuous androgen deprivation (hormone therapy) and intermittent androgen deprivation. In early 2012, it was discovered that intermittent androgen deprivation is equal in long-term survival to continuous androgen deprivation. A new paradigm of treatment, in which androgen deprivation was given for eight to nine months and then discontinued if the prostate specific antigen normalized, was published. Re-treatment is recommended only when the PSA level becomes greater than 10 with monitoring every two months.
