Current chapter – Core – Site specific staging


Introduction

These are required to record and improve the tumour specific ‘site specific stage’. Whilst the date is mandatory, the organisational code has been dropped to required, however it would still be expected to be submitted where known.

These data items would only be reported if there is a linked site specific stage also reported. Please refer to the individual tumour specific sections where there is a site specific stage, for example:

  • Central Nervous System (CTYA)
    • Chang Staging System Stage
  • Children Teenage and Young Adults (CTYA)
    • Wilms Tumour Stage
    • International Neuroblastoma Risk Group (INRG) Staging System
    • Pretext Staging System Stage
    • Pretext Annotation Factors
    • International Staging System for Retinoblastoma
  • Gynaecological
    • Figo Stage
  • Haematological
    • Ann Arbor Stage
    • Binet Stage
    • R-ISS Stage for Myeloma
  • Haematology (CTYA)
    • Murphy (St Jude) Stage
    • Children’s Oncology Group (Cog) Staging System Stage
    • Central Nervous System Involvement
  • Liver
    • Barcelona Clinic Liver Cancer (BCLC) Stage
  • Urology (Testicular)

Organisation Site Identifier (Site Specific Stage)

This is the 'Organisation Identifier' of the 'Organisation Site' who carried out the site specific stage.

Notes:

  • this data item has reverted to ‘Required’, to support data collection where the reporting Trust does not know the organisation or MDT that confirmed the site specific stage
  • in most cases it would be the MDT that provides all the details to make a site specific stage, as it may require a combination of clinical, radiological, and sometimes pathological input
    • therefore, use the organisation that hosted the MDT

Stage Date (Site Specific Stage)

The date of the sample or MDT that provided a positive stage result. This is mandatory; therefore, the section cannot be submitted without this field completed

Notes:

  • in most cases it would be the MDT that provides all the details to make a site specific stage, as it may require a combination of clinical, radiological, and sometimes pathological input
    • in these cases, use the date of the MDT that reported the stage
  • if only a pathological sample resulted in the positive stage result
    • in these cases, use the date the sample was reported
  • if in doubt, always consult the MDT lead or clinical champion for more details
