Objectives - Determine the efficacy of finasteride and flutamide in suppressing prostate specific antigen (PSA) levels in patients with elevated PSA after definitive radiation therapy or radical prostatectomy for prostate cancer.
- Assess sexual function and other quality of life issues during this therapy.
- Estimate the response to flutamide withdrawal in this group of patients who have not had a major reduction in circulating testosterone levels.
- Measure the response rate to further hormonal manipulation with combined androgen blockade after the failure of this therapy.
- Obtain data that may predict more aggressive disease.
Entry Criteria Disease Characteristics:
- Histologically proven previously treated adenocarcinoma of the prostate
- Prior definitive therapy must have occurred at least 6 months, but no
more
than 10 years, prior to study
- Definitive therapy is defined as one of the following:
- Prior radical prostatectomy
- Radiotherapy to the prostate no more than 3 months
before prostatectomy
- Brachytherapy
- Brachytherapy with external beam radiotherapy given as
single therapy
- External beam radiation therapy alone
- Must have a PSA level between 1-10 nu/mL, with a rise of at least 1 nu/mL above the nadir produced by definitive therapy
- No evidence of local recurrence
- No metastatic disease
Prior/Concurrent Therapy:
Biologic therapy: Chemotherapy: - No prior chemotherapy for prostate cancer
Endocrine therapy: - At least 2 years since finasteride or other 5a-reductase
inhibitors
- At least 12 months since prior hormone therapy for prostate
cancer
- No more than 6 months of prior hormone therapy
- No corticosteroids in excess of standard replacement
doses
- No concurrent systemic steroids
- No other concurrent antiandrogenic drugs or 5a-reductase
inhibitors
Radiotherapy: - See Disease Characteristics
- No concurrent palliative radiotherapy
Surgery: - See Disease Characteristics
- No orchiectomy
Patient Characteristics:
Age: Performance status: Life expectancy: Hematopoietic: Hepatic: - Bilirubin no greater than 2 times upper limit of normal
(ULN)
- SGOT/SGPT no greater than 2 times ULN
Renal: - Creatinine no greater than 2 times ULN
Other: - Fertile patients must use effective contraception
Expected Enrollment 100This study will accrue 100 patients over 2 years. Outline This is a multicenter study. Patients receive finasteride and flutamide by mouth three times a day.
Patients experiencing recurrence or a greater than 4 nu/mL (above 50%)
increase in PSA level will discontinue flutamide treatments. Otherwise,
patients continue therapy in the absence of unacceptable toxicity or disease
progression. Quality of life is assessed prior to therapy and at 3 and 6
months. Patients are followed every 3 months for one year and every 6 months
thereafter. Published ResultsPicus J, Halabi S, Small E, et al.: Long term efficacy of peripheral androgen blockade on prostate cancer: CALGB 9782.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. Back to Top |
