To evaluate the rate and duration of prostate-specific antigen (PSA) response to high-dose bicalutamide (150 mg) in nonmetastatic castration-resistant prostate cancer patients and its impact on metastasis-free survival. ⋯ High-dose bicalutamide can induce a second response in almost half of castration-resistant prostate cancer patients without metastasis. The duration of response is more than 1.5 years on average and responders have prolonged metastasis-free survival.
