Details on how to use National Cancer Data Standards for Wales Core and Site-specific DSCNs:
All site-specific cancer minimum reporting requirements should be used in conjunction with National Cancer Data Standards for Wales – Core (DSCN 2019 / 09).
Core data items should be collected for all cancers. To reduce replication of information, Core data items have not been listed in the site-specific Standards and users should refer to National Cancer Data Standards for Wales – Core (DSCN 2019 / 09) for a list of Core requirements.
However, in some cases, the site-specific application of Core data items may differ e.g. a particular tumour site may require additional or fewer codes to those already published in Core, or perhaps have additional business rules as to how the Core data item should be coded. Where this occurs, the Core data item will be replicated in the site-specific Standard with the respective additional site-specific detail. These are flagged in the relevant tables with an * next to the data item name.
