(1) “Data sources and collection processes” outlines the data sources used, as well as the processes and timing of data collection utilised by population-based cancer registries. Results: The findings of the 23 included articles published between 20 consisted of two themes. Included literature were analysed using thematic analysis and managed through NVivo. Database results were screened by title and abstract using Research Screener. Literature was excluded if they were reviews or only the abstract was available. Literature was included if peer-reviewed articles or grey literature sources used population-based cancer stage at diagnosis, and were published in English between 20.


A systematic search of peer-reviewed research studies and grey literature from 2000 to 2021 was conducted in December 2021. Methods: This review was guided by the Joanna-Briggs Institute methodology. This review aimed to explore how cancer stage at diagnosis is determined in population-based cancer registries. The lack of standardised collection of cancer staging in Australia is well recognised and is not routinely collected within the Western Australia Cancer Registry. This data enables analysis of cancer burden by stage, evaluation of screening programs and provides insight into differences in cancer outcomes. Introduction: Population-based cancer registries are the main source of data for population-level analysis of cancer stage at diagnosis.
