Summary
Brief summary (as posted)
RATIONALE: Gene mutations may make prostate cancer cells unable to attach to androgens. This may permit the growth of prostate cancer. Gene testing may improve the identification of patients with advanced prostate cancer. PURPOSE: Clinical trial to study the androgen receptor gene in patients with prostate cancer that is not responsive to hormone therapy.

- description
- The CALGB conducted a phase III study (CALGB 9583) in which 260 men with AiPC were randomly assigned to antiandrogen withdrawal together with simultaneous ketoconazole and hydrocortisone versus antiandrogen withdrawal alone, followed by sequential ketoconazole and hydrocortisone. Metastatic disease with progression despite castrate levels of testosterone, prior antiandrogen therapy for a minimum of 4 weeks, and a minimum PSA level of 5 ng/mL were required; treatment with sequential antiandrogens was allowed. No prior chemotherapy was allowed. Bone marrow biopsies were obtained from 164 patients enrolled on CALGB 9583 and from 20 patients enrolled on CALGB chemotherapy trials (CALGB 9480, 9680, 9780).
