Population-based cancer registries are crucial for tracking cancer trends, supporting research, guiding policy decisions, and ensuring efficient healthcare resource allocation. However, their effectiveness relies heavily on data quality, specifically the completeness of the cancer registration process. Background/Objectives: This systematic review aims to identify the methods used by adult population-based cancer registries worldwide to assess the completeness of their data. It also considered the significant role of high-quality data in method selection and the significant challenges of data handling. Methods: A comprehensive electronic literature search was conducted across the Web of Science, Scopus, and PubMed for studies published from January 2004 to December 2024. The review was written according to PRISMA guidelines, and the risk of bias was assessed using the Joanna Briggs Institute tool. Results: The review identified 83 studies from 31 countries, the majority from Europe, especially Nordic and Central European countries. Most studies met high-quality standards, with only one study scoring below 75%. Common approaches include independent case ascertainment (the most used), a capture–recapture analysis, a death-certificate-only analysis, and comparisons with historical rates. While independent case ascertainment is valuable when high-quality auxiliary sources are available, its accuracy varies. Other methods, like capture-recapture or Mortality-to-Incidence ratios, may be more accurate or feasible in some cases. Conclusions: The findings suggest that methods for completeness evaluations vary widely across registries, influenced by data quality and regional practices. The results emphasize the importance of the continuous refinement of these assessment methods to improve the reliability and global comparability of cancer registry data.
基于人群的癌症登记系统对于追踪癌症趋势、支持研究、指导政策决策以及确保医疗资源高效配置至关重要。然而，其有效性在很大程度上依赖于数据质量，特别是癌症登记过程的完整性。背景/目的：本系统综述旨在识别全球成人人群癌症登记系统用于评估数据完整性的方法，同时探讨高质量数据在方法选择中的重要作用以及数据处理面临的主要挑战。方法：在Web of Science、Scopus和PubMed数据库中，对2004年1月至2024年12月发表的研究进行了全面的电子文献检索。综述依据PRISMA指南撰写，并使用乔安娜·布里格斯研究所工具评估偏倚风险。结果：综述共纳入来自31个国家的83项研究，其中大部分来自欧洲，尤其是北欧和中欧国家。大多数研究符合高质量标准，仅有一项研究评分低于75%。常见方法包括独立病例确认（使用最广泛）、捕获-再捕获分析、仅死亡证明分析以及与历史发病率的比较。尽管在具备高质量辅助数据源时，独立病例确认方法具有重要价值，但其准确性存在差异。在某些情况下，其他方法如捕获-再捕获或死亡率-发病率比值法可能更为准确或可行。结论：研究结果表明，不同登记系统采用的完整性评估方法差异显著，这受到数据质量和地区实践的影响。结果强调了持续优化这些评估方法的重要性，以提升癌症登记数据的可靠性和全球可比性。
