PSA provocation by bipolar androgen therapy may predict duration of response to first-line androgen deprivation: Updated results from the BATMAN study.

The use of BAT as part of first-line hormonal therapy strategy does not induce adversely affect long-term survival or induce any significant long-term adverse sequelae in patients with prostate cancer. Cycling BAT may extend the duration of ADT response and enhance response to subsequent androgen ablative therapies. The magnitude of BAT-provoked increase in PSA may predict duration of ADT response and warrants further study.
