Adjuvant And Salvage Radiotherapy After Prostatectomy: Aua/Astro Guideline Amendment 2018.

Purpose: The purpose of this amendment is to incorporate newly-published literature into the original ASTRO/AUA Adjuvant and Salvage Radiotherapy after Prostatectomy Guideline and to provide an updated clinical framework for clinicians. Materials and Methods: The original systematic review yielded 294 studies published between January 1990 and December 2012. In April 2018, the guideline underwent an amendment and incorporated 155 references that were published from January 1990 through December 2017. Two new key questions were added. One on the use of genomic classifiers and the other on the treatment of oligo-metastases with radiation post-radical prostatectomy. Results: A new statement on the use of hormone therapy with salvage radiotherapy after radical prostatectomy was added and long-term data was used to update an existing statement on adjuvant radiotherapy. The balance of the guideline statements were re-affirmed and references were added to the existing literature base. A discussion on the use of genomic classifiers as a risk stratification tool was added to the future research discussion. No relevant data on oligo-metastases was found. Conclusions: Hormone therapy should be offered to patients who have had radical prostatectomy and who are candidates for salvage radiotherapy. The clinician should discuss possible short- and long-term side effects with the patient as well as the potential benefits of preventing recurrence. The decision to use hormone therapy should be made by the patient and a multi-disciplinary team of providers with full consideration of the patient's history, values, preferences, quality of life, and functional status.
