Guideline Development Process

  • In accordance with established ASTRO policy, the guidelines subcommittee, of ASTRO’s Clinical Affairs and Quality Council, recruits a guideline panel of recognized topic experts, patients and caregiver representatives. The guideline panel members are drawn from academic settings, private practice and residency. The ASTRO Board of Directors approves the topic proposal and panel membership. The guideline panel, with ASTRO staff support, completes a systematic review, creates literature tables and formulates the recommendation statements and narratives for the guideline. A draft is placed on the ASTRO website for public comment. Following integration of the feedback, the document is submitted for approval to the ASTRO Board of Directors.

    Clinician practice statements are prepared based on information available at the time the panel was conducting its research and discussions on the guideline topic. There may be new developments that are not reflected in the guidelines and that may, over time, be revisited and updated. 

    Completed ASTRO guidelines are published in one of ASTRO's journals:

    Status terminology:

    • Reaffirmed - confirmation of the validity and correctness based on current evidence
    • Replacement - a complete replacement of a prior statement
    • Update - a revised version based on new evidence and/or clinical studies
    • Withdrawn - a previous statement no longer supported by current evidence
  • ASTRO’s Guideline Development Process is very involved and includes five main phases.
