This guideline has been updated. This ASCO Living Guideline is reviewed on an eight-week cycle. Please see the online dynamic version for the latest updates. Living guidelines are developed for selected topic areas with rapidly evolving evidence that drives frequent change in recommended clinical practice. Living guidelines are updated on a regular schedule by a standing expert panel that systematically reviews the health literature on a continuous basis, as described in the ASCO Guidelines Methodology Manual . ASCO Living Guidelines follow the ASCO Conflict of Interest Policy Implementation for Clinical Practice Guidelines . Living Guidelines and updates are not intended to substitute for independent professional judgment of the treating clinician and do not account for individual variation among patients. See appendix for disclaimers and other important information ( Appendix 1 and Appendix 2 ). Updates are published regularly and can be found at www.asco.org/genitourinary-cancer-guidelines .

Purpose In April 2017, the American Urological Association, American Society for Radiation Oncology, and Society of Urologic Oncology released a joint evidence-based practice guideline on clinically localized prostate cancer. The American Society of Clinical Oncology (ASCO) has a policy and set of procedures for endorsing clinical practice guidelines that have been developed by other professional organizations. Methods The Clinically Localized Prostate Cancer guideline was reviewed for developmental rigor by methodologists. An ASCO Expert Panel then reviewed the content and the recommendations. Results The ASCO Expert Panel determined that the recommendations from the Clinically Localized Prostate Cancer guideline were clear, thorough, and based upon the most relevant scientific evidence. ASCO endorsed the Clinically Localized Prostate Cancer guideline except for two recommendations on cryosurgery. The two recommendations covering cryosurgery were not endorsed because the panel found that there is insufficient evidence to support the use of cryotherapy in this setting. Recommendations The ASCO Expert Panel endorsed all but two of the original guideline recommendations as written and offered a series of discussion points to guide practice.
