Radiotherapy Data Set Overview


The Radiotherapy Data Set (RTDS) allows for the routine collection of clinically and managerially relevant ACTIVITY data from Radiotherapy centres to provide operational data to enable bench marking and to support enhancing clinical practice, in addition to commissioning or monitoring Radiotherapy Services in an evidence-based manner.

Radiotherapy is a major modality in the treatment of cancer and also represents a significant sector within the NHS, in terms of both workforce and capital investment.

All NHS funded facilities in England providing Radiotherapy Services are required to return data to Public Health England (PHE) for all ACTIVITY undertaken on External Beam Radiotherapy (Teletherapy) and Brachytherapy MACHINES, or with radioisotopes not contained within an External Beam Radiotherapy (Teletherapy) or Brachytherapy MACHINE.

The Radiotherapy Data Set accompanies the Out-Patient Commissioning Data Set for PATIENTS attending for Radiotherapy.

Where admitted PATIENTS attend for Radiotherapy, a Radiotherapy Attendance record should be submitted to Public Health England along with the Out-Patient Commissioning Data Set for the In-Patient Attendance.

Data Submission

The Radiotherapy Data Set should be submitted to Public Health England by the 20th working day of each month. The extracts should include all Radiotherapy Attendance records for the previous calendar month.

Data should be submitted using the National Cancer Registration and Analysis Service (NCRAS) upload portal at: NCRAS Login.

Further Guidance

Further guidance for submission of the Radiotherapy Data Set is provided by the National Disease Registration Service at: National Radiotherapy Data Set (RTDS).
