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.

Description of Systematic Review
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.
List of Questions
This clinical practice guideline considered the following clinical questions: (1) In adults treated with chemotherapy for a solid tumor or lymphoma, what factors should clinicians consider when selecting patients for primary prophylaxis of febrile neutropenia with hematopoietic colony-stimulating factors (CSFs)? (2) In adults treated with chemotherapy for a solid tumor or lymphoma, what factors should clinicians use to select patients for secondary prophylaxis of febrile neutropenia with a CSF? (3) Are there circumstances in which CSFs should be considered for the treatment of neutropenia in adults with cancer? (4) In what settings should CSFs be used to increase chemotherapy dose density? (5) What is the role of CSFs as adjuncts to progenitor-cell transplantation? (6) What is the role of CSFs in the setting of acute leukemia or myelodysplastic syndromes? (7) Should CSFs be avoided in patients receiving concomitant chemotherapy and radiation therapy? (8) Are there CSF recommendations that apply specifically to older adults and that differ from recommendations in younger adults? (9) How should CSFs be used in the pediatric population? (10) What are recommendations for the initiation, duration, dosing, and administration of CSFs? (11) Do CSFs differ in efficacy? (12) What is the role of CSFs in the treatment of radiation injury?
Description of Study Criteria
Description of Search Strategy
Upon approval of the Protocol, a systematic review of the medical literature is conducted. ASCO staff use the information entered into the Protocol, including the clinical questions, inclusion/exclusion criteria for qualified studies, search terms/phrases, and range of study dates, to perform the systematic review. Literature searches of selected databases, including The Cochrane Library and Medline (via PubMed) are performed. Working with the Expert Panel, ASCO staff complete screening of the abstracts and full text articles to determine
eligibility for inclusion in the systematic review of the evidence.
Unpublished data from meeting abstracts are not generally used as part of normal ASCO guideline development (“Meeting Data”). However, abstract data from reputable scientific meetings and congresses may be included on a case‐by‐case basis after review by the CPGC leadership. Expert Panels should present a rationale to support integration of abstract data into a guideline. The CPGC leadership will consider the following inclusion criteria for the unpublished scientific meeting data: 1) whether the data were independently peer reviewed in connection with a reputable scientific meeting or congress; 2) the potential clinical impact of the unpublished data; 3) the methodological quality and validity of the associated study; 3) the potential harms of not including the data; and 4) the availability of other published data to inform the guideline recommendations.
Description of Study Selection
Literature search results were reviewed and deemed appropriate for full text review by two ASCO staff reviewers in consultation with the Expert Panel Co-Chairs. Data were extracted by two staff reviewers and subsequently checked for accuracy through an audit of the data by another ASCO staff member. Disagreements were resolved through discussion and consultation with the Co-Chairs if necessary. Evidence tables are provided in the manuscript and/or in Data Supplement.
Description of Evidence Analysis Methods
ASCO guideline recommendations are crafted, in part, using the GuideLines Into DEcision Support (GLIDES) methodology. ASCO adopted a five‐step approach to carry out quality appraisal, strength of evidence ratings and strength of recommendations ratings. The ASCO approach was primarily adapted from those developed by the AHRQ,, USPSTF, and GRADE, however with the validation of the GRADE methodology, the sole use of GRADE is being evaluated by the Clinical Practice Guidelines Committee.
Description of Evidence Grading
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.
Description of Recommendation Grading
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.
