Management of Unfavorable Intermediate-Risk Prostate Cancer: Role of SBRT, Brachytherapy and Androgen Deprivation
Unfavorable intermediate-risk prostate cancer is commonly encountered in clinical practice but there is relatively little data focusing on treatment outcomes specific and limited to this patient cohort, with most clinical trials grouping these patients with favorable intermediate-risk disease or with high-risk disease. There is considerable interest in using SBRT or brachytherapy in this patient population as well as interest in use of genomic risk stratification tools (e.g., Decipher assay) to make decisions on the use and duration of ADT. The NRG recently opened the first trial in unfavorable intermediate-risk disease, NRG GU 010, to explore the use of genomic risk stratification to identify patients who could be candidates for treatment de-intensification or treatment intensification with systemic therapy.

Full Panel
This activity is available from March 11, 2025, through 11:59 p.m. Eastern time on March 10, 2027.
The content was originally presented and recorded at the 2024 ASTRO Annual Meeting.
Target Audience
The activity is designed to meet the interests of medical oncologists, radiation oncologists and residents.
Learning Objectives
Upon completion of this activity, participants should be able to:
- Describe the optimal patients with unfavorable intermediate-risk disease who are candidates for prostate SBRT, analyze the appropriate dose of SBRT, and gain comfort in defining the MR-detected lesion(s) to do focal micro-boost to gross disease.
- Describe the potential value of EBRT plus brachytherapy boost for unfavorable intermediate-risk vs. brachytherapy without EBRT and to analyze the role of ADT in combination with brachytherapy for unfavorable intermediate-risk disease.
- Analyze the role of genomic risk stratification tools to make determinations on the use of ADT as well as the duration of ADT including discussion of the currently accruing NRG GU 010 trial in this disease space.
