We appraised the quality and reporting of CPGs and CSs for breast cancer (BC) treatment. Methods: Following protocol registration (Prospero no: CRD42020164801), CPGs and CSs on BC treatment were identified, without language restrictions, through a systematic search of bibliographic databases (MEDLINE, EMBASE, Web of Science, Scopus, CDSR) and online sources (12 guideline databases and 51 professional society websites) from January 2017 to June 2020. Data were extracted in duplicate assessing overall quality using AGREE II (% of maximum score) and reporting compliance using RIGHT (% of total 35 items); reviewer agreement was 98% and 96% respectively. Results: There were 59 relevant guidance documents (43 CPGs, 16 CSs), of which 20 used systematic reviews for evidence synthesis. The median overall quality was 54.0% (IQR 35.9-74.3) and the median overall reporting compliance was 60.9% (IQR 44.5-84.4). The correlation between quality and reporting was 0.9. Compared to CSs, CPGs had better quality (55.4% vs 44.2%; p = 0.032) and reporting (67.18% vs 44.5%; p = 0.005). Compared to subjective methods of evidence analysis, guidance documents that used systematic reviews had better quality (76.3% vs 51.4%; p = 0.001) and reporting (87.1% vs 59.4%; p = 0.001). Conclusion: The quality and reporting of CPGs and CSs in BC treatment were moderately strong. Systematic reviews should be used to improve the quality and reporting of CPGs and CSs.enAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Breast cancerTreatmentClinical practice guidelinesGuidelinesConsensusAGREE IIRIGHTAppraisal instrumentsQuality of guidelinesNeoplasias de la mamaTerapéuticaGuía de práctica clínicaGuías como asuntoConsensoRevisión sistemáticaMedical Subject Headings::Diseases::Neoplasms::Neoplasms by Site::Breast NeoplasmsMedical Subject Headings::Psychiatry and Psychology::Behavior and Behavior Mechanisms::Psychology, Social::Group Processes::ConsensusMedical Subject Headings::Check Tags::FemaleMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Health Care::Health Services Administration::Quality of Health Care::Quality Assurance, Health Care::Guidelines as Topic::Practice Guidelines as TopicMedical Subject Headings::Information Science::Information Science::Medical Informatics::Medical Informatics Applications::Information Systems::Databases as Topic::Databases, BibliographicQuality and reporting of clinical guidelines for breast cancer treatment: A systematic reviewreview article32858405open access10.1016/j.breast.2020.07.011PMC7473996
