Background: Given the distinct biological characteristics and regional distribution of nasopharyngeal carcinoma (NPC) compared with other head and neck cancers, and uncertainties regarding therapeutic strategies, physicians require high-quality clinical practice guidelines (CPGs) to provide transparent recommendations for NPC treatment. This study aimed to critically appraise the quality of NPC CPGs and assess the consistency of their recommendations. Methods: We identified CPGs that provided recommendations on the diagnosis and management of NPC published up to December 2015. Four investigators independently appraised CPG quality using the Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument. Key recommendations by CPGs were also evaluated. Results: A total of 7 CPGs were eligible for this study: 5 produced by professional organizations or governmental agencies and 2 were developed based on expert consensus. Of the 6 AGREE II domains, the applicability domain scored consistently low across CPGs (range, 13.5%-30.2%); no CPG achieved a score of >50% in all 6 domains. The scope and purpose domain (≥73.6% for 4 CPGs) and editorial independence domain (≥75.0% for 6 CPGs) scored highest. Of the 23 AGREE II items, 9 scored less than half of the points available in all 7 CPGs. The recommendations by CPGs were consistent in general; heterogeneity mainly existed among recommended therapeutic strategies. Conclusions: Variation exists in NPC CPG development processes and recommendations. Increased efforts are required to make comprehensive resources available to guide healthcare providers and enhance delivery of high-quality, evidence-based care for NPC. International collaboration is necessary to enable the development of high-quality and regionally relevant CPGs for NPC.
