Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what steps his Department is taking to improve the collection of data on triple-negative breast cancer.

Data on triple negative breast cancer for England is collected through the National Disease Registration Service (NDRS). An NDRS Quality Assurance Team is in place to identify, investigate, and monitor data quality issues, with over 130 Quality Assurance reports being run each month as well as quarterly reports to assess the completeness of key data.

To drive up the completeness of the data, progesterone receptor status, human epidermal growth factor receptor in situ hybridization status, and oestrogen receptor status are assessed as part of the Cancer Outcomes and Services Data set, which supports national registration.
