ASCO's evidence-based clinical guidance documents include:

  • Guidelines
  • Guideline Endorsements
  • Guideline Adaptations
  • Consensus Guidelines
  • Provisional Clinical Opinions (PCOs)

ASCO disseminates this guidance and provides support for implementation in various media. All evidence-based clinical guidance documents are published in the Journal of Clinical Oncology (JCO).

Data supplements and methodology supplements are published on

ASCO develops Clinical Tools and Resources (CT&Rs) to accompany clinical guidance documents. For each guideline, ASCO develops a PowerPoint slide set, a Summary of Recommendations Table, and a patient guide. If applicable to the topic, the Society could also develop a decision aid/discussion guide, flow sheet, or algorithm.

ASCO promotes the guidelines using other communication strategies. These include notices on ASCO's Facebook account, the ASCO Express, ASCO Connection, ASCO Post, and other membership communication outlets. In addition, ASCO develops press releases for the Media. ASCO also promotes guideline dissemination and implementation through its Annual Meetings, disease-specific symposia, and State Affiliates.

Quality indicator statements may be developed for the guidelines and may result in quality measures used in ASCO’s Quality Oncology Practice Initiative (QOPI). Members of the Practice Guidelines Implementation Network (PGIN) act as ambassadors and use a grassroots approach to inform others about ASCO's Guidelines and Clinical Tools and Resources.
