How should synchronous tumours be entered?

Synchronous (multifocal) tumours are defined as discrete tumours apparently not in continuity with other primary cancers originating in the same site or tissue. The audit only collects the full dataset on the primary tumour i.e. the tumour that requires the ‘biggest’ procedure to deal with it. However, if these are identified by the clinician at presentation, they can be recorded in the data item ‘Synchronous Cancer’ and multiple sites can be selected.
