ADT and SBRT vs SBRT Alone for Unfavorable Intermediate Risk Prostate Cancer
Trial Parameters
Brief Summary
For this study, unfavorable intermediate risk prostate cancer patients will select whether they are to be treated with the standard of care (SOC) 6 months of Androgen Deprivation Therapy (ADT) in conjunction with stereotactic body radiation therapy/radiosurgery (SBRT) directed to the prostate versus SBRT alone. The patient population will include those with National Comprehensive Cancer Network (NCCN)-defined unfavorable intermediate risk disease. All patients will be followed every 6 months for up to 5 years from the first patient treated and will undergo a routine 24-30 months post-SBRT prostate biopsy to assess for local tumor control.
Eligibility Criteria
Inclusion Criteria: * Biopsy proven unfavorable intermediate risk prostate cancer, which includes patients with any one of the following variables: Gleason 4+3 disease; Percent positive cores \> 50% of Gleason 7 disease; 2-3 intermediate risk factors (Gleason 7; PSA 10-20 ng/mL; or T2b-T2c) * Patients must have tissue available for Decipher score testing. Results must be available before start of treatment. * Serum testosterone ≥ 150 ng/dL determined within 2 months prior to enrollment * At least 4 weeks must have elapsed from major surgery * Karnofsky Performance Scale (KPS) ≥ 80% * Prostate size as determined on MRI to be \< 90 cc. Prostate size can be determined on CT scan if MRI is not available * IPSS ≤ 20 * Patient must be available for follow-up. After 2 years of follow-up, upon completion of post-treatment biopsy, telephone and chart review-based follow-up will be acceptable * Adequate hepatic function with serum bilirubin less than or equal to 1.5 times the upper institutional
