SAN DIEGO, May 7, 2013 /PRNewswire/ -- The American Society for Radiation Oncology (ASTRO) and the American Urological Association (AUA) are pleased to announce the publication of the joint guideline on radiation therapy after prostatectomy for patients with and without evidence of prostate cancer recurrence. The 81-page document represents an intensive collaboration among experts in the radiation oncology and urology fields, led by Richard K. Valicenti, MD, MA, professor and chair of the department of radiation oncology at the University of California Davis Comprehensive Cancer Center in Sacramento, on behalf of ASTRO, and Ian M. Thompson, MD, director of the Cancer Therapy and Research Center at the University of Texas Health Science Center at San Antonio and the Glenda and Gary Woods Distinguished Chair in genitourinary oncology, on behalf of the AUA. The Adjuvant and Salvage Radiotherapy After Prostatectomy: ASTRO/AUA Guideline is a comprehensive review of 324 research articles of English-language publications within the Pubmed, Embase and Cochrane databases, published from January 1, 1990 through December 15, 2012. The guideline is available online free as a PDF document at www.redjournal.org and www.auanet.org, and will be published in the August 1, 2013, print issue of the International Journal of Radiation Oncology • Biology • Physics (Red Journal), the official scientific journal of ASTRO, and in the August 2013 print issue of The Journal of Urology, the official journal of the AUA. The strategies and approaches recommended were derived from evidence-based and consensus-based processes in the reviewed articles. The systematic review included articles that provided detailed efficacy in patients with detectable and undetectable prostatic specific antigen (PSA) levels, toxicity and quality of life impact, and optimal imaging strategies to determine the appropriateness of radiation therapy use in patients suspected of recurrence. Only studies in which PSA data were provided for 75 percent or more patients were included in the guideline.
