Early Detection of Colorectal Cancer

ASCO has a rigorous review process for guidelines. After the draft has been approved by the Expert Panel, the guideline is independently reviewed and approved by the Clinical Practice Guideline Oversight Committee (CPGC). Select members of the CPGC are asked to critically review the guideline prior to the next scheduled CPGC meeting. The CPGC members then present the results of their reviews to the full committee, discuss the review with the full committee, and the CPGC votes on whether to approve the guideline (with recusals from members who have relationships with affected companies). Approved ASCO Guidelines are then submitted to the Society’s journal for consideration of publication.

ASCO Guidelines are available for open comment for a 2 to 3‐week period. Guideline recommendations available for open comment are posted on asco.org/open‐comment‐guidelines. Prospective reviewers must contact ASCO to request to review the draft guideline recommendations and are required to sign a non‐disclosure and confidentiality agreement before receiving the draft guideline recommendations. Reviewers must identify themselves by name and affiliation; anonymous comments will not be accepted. Guidelines staff review and summarize comments and bring relevant comments to the Expert Panel Co‐ chairs, and to the entire panel if necessary. Any changes made from the open comment process will be reviewed by the entire panel prior to CPGC approval. Comments are advisory only and ASCO is not bound to make any changes based on feedback from open comment. ASCO does not respond to reviewers or post responses to comments; however, major edits to the draft will be reflected in the open comment discussion.

The Protocol specifies the purpose of the guideline product, target patient population, clinical outcomes of interest, key features of the systematic literature review, and a proposed timeline for completion. ASCO staff, the Expert Panel Co‐Chairs, and possibly other panel members selected by the Co‐Chairs (the Expert Panel Steering Committee), will typically draft the protocol for full panel review. A standard protocol worksheet is used for consistency. Once the Co‐Chairs have approved a first draft of the Protocol, the Protocol will be shared with the full Expert Panel. At the discretion of the Guidelines Director, the CPGC leadership and/or the CPGC Methodology Subcommittee may review the Protocol to make suggestions for revision intended to clarify aspects of the plan for developing the guideline. These suggestions are sent to the Expert Panel Co‐Chairs. Work on the systematic literature review can proceed upon the sign‐off of the Protocol by the Expert Panel.

High: High confidence that the available evidence reflects the true magnitude and direction of the net effect (i.e., balance of benefits v harms) and that further research is very unlikely to change either the magnitude or direction of this net effect. Intermediate: Moderate confidence that the available evidence reflects the true magnitude and direction of the net effect. Further research is unlikely to alter the direction of the net effect; however, it might alter the magnitude of the net effect. Low: Low confidence that the available evidence reflects the true magnitude and direction of the net effect. Further research may change either the magnitude and/or direction this net effect. Insufficient: Evidence is insufficient to discern the true magnitude and direction of the net effect. Further research may better inform the topic. The use of the consensus opinion of experts is reasonable to inform outcomes related to the topic.

ASCO uses a formal consensus methodology based on the modified Delphi technique in clinically important areas where there is limited evidence or a lack of high‐quality evidence to inform clinical guidance recommendations. Evidence Based: There was sufficient evidence from published studies to inform a recommendation to guide clinical practice. Formal Consensus: The available evidence was deemed insufficient to inform a recommendation to guide clinical practice. Therefore, the Expert Panel used a formal consensus process to reach this recommendation, which is considered the best current guidance for practice. The Panel may choose to provide a rating for the strength of the recommendation (i.e., "strong," "moderate," or "weak"). The results of the formal consensus process are summarized in the guideline and reported in the Data Supplement (see the Supporting Documents" field). Informal Consensus: The available evidence was deemed insufficient to inform a recommendation to guide clinical practice. The recommendation is considered the best current guidance for practice, based on informal consensus of the Expert Panel. The Panel agreed that a formal consensus process was not necessary for reasons described in the literature review and discussion. The Panel may choose to provide a rating for the strength of the recommendation (i.e., "strong," "moderate," or "weak"). No recommendation: There is insufficient evidence, confidence, or agreement to provide a recommendation to guide clinical practice at this time. The Panel deemed the available evidence as insufficient and concluded it was unlikely that a formal consensus process would achieve the level of agreement needed for a recommendation.

ASCO provides funding for Guideline Development.

ASCO Conflict of Interest Policy complies with the CMSS Code for Interactions with Companies. ASCO requires disclosure by individuals involved in drafting, reviewing, and approving guideline recommendations.
