Clinical Practice Statements

  • ASTRO's commitment to improving patient care and safety can be seen through many of our initiatives. Clinical practice tools,such as guidelines and white papers, products to ensure patient safety, like APEx, RO-ILS and IHE-RO and research support opportunities are all professional tools created to assist with patient care.

    Additionally, ASTRO has created educational materials such as brochures, videos and PowerPoints to enable our members and referring physicians explain radiation therapy to patients while assisting them in their treatment decisions.

    Postmastectomy Radiotherapy: An American Society of Clinical Oncology, American Society for Radiation Oncology, and Society of Surgical Oncology Focused Guideline Update (2016)

    Authors: Abram Recht, Elizabeth A. Comen, Richard E. Fine, Gini F. Fleming, Patricia H. Hardenbergh, Alice Y. Ho, Clifford A. Hudis, E. Shelley Hwang, Jeffrey J. Kirshner, Monica Morrow, Kilian E. Salerno, George W. Sledge, Jr, Lawrence J. Solin, Patricia A. Spears, Timothy J. Whelan, Mark R. Somerfield, Stephen B. Edge

    This update to the ASCO guideline on use of postmastectomy radiotherapy (PMRT) focused on key areas of ongoing controversy, including the use of PMRT for patient with one to three positive lymph nodes or who are undergoing neoadjuvant systemic therapy; selected technical aspects of PMRT, particularly the extent of regional nodal irradiation; and whether PMRT is indicated in women with T1-2 tumors and a positive sentinel node biopsy who do not undergo completion axillary lymph node dissection.

  • Collaboration on clinical guideline development can improve the delivery and consistency of quality medical care. Collaborative guidelines are intended to minimize duplication of effort, increase guideline production and harmonize recommendations for the benefit of radiation oncology professionals and patients. Organizations that request to collaborate with ASTRO in the development of a clinical practice guideline will meet the following requirements:

    1. Propose a topic that has a reasonable amount of high-quality evidence and considerable variation in radiation oncology practice.
    2. Specify needed resources including costs, staff roles and responsibilities.
    3. Utilize a clinical guideline development process that is aligned with the IOM’s guideline development standards including: transparency, management of Conflicts of Interest, multidisciplinary composition of the guideline development group, systematic review of the evidence, description of evidence foundations for rating the strength of the recommendations, articulation of clear recommendations and identification of methods for updating and revising the guideline.
    4. Explicitly rate the strength of evidence and strength of recommendations. The guideline will need to include information about the rating of the strength of the evidence and the strength of recommendation.
    5. Provide ASTRO with the authority to offer meaningful input into the final document in a timeframe consistent with ASTRO’s clinical practice guideline processes, allowing a minimum of three months for review. There will need to be agreed upon formal review processes including expert review and/or public comment as well as Board approval.
    6. Specify dissemination approaches such as publication, copyrights and marketing. The guideline should be published in the lead organization’s journal and be an open access article. A joint press release from all societies will be released.
    7. Ability to opt out of the guideline if there are substantive concerns.

    We believe that these criteria will provide a reasonable framework for guiding decisions related to collaboration with other organizations in the development of clinical practice guidelines.
