The most common types of radiotherapy are:
• External beam radiotherapy (teletherapy)
• Radioactive sources (Brachytherapy)
What is Radiotherapy? 2 of 3
External beam radiotherapy is*
96% of all radiotherapy delivered
*Approximately, based on 19/20 submissions
![Page 7: The Radiotherapy Dataset · 2020. 11. 18. · Mosaiq. •Dataset documented and available on request 25 Public Health England25 OverviewPublic Health England Submissions –the Elekta](https://reader035.fdocuments.in/reader035/viewer/2022071415/6110d9a5843c466a3a3c8538/html5/thumbnails/7.jpg)

Radiation delivered from multiple angles
to prevent accumulation of dose in
surrounding healthy tissue
External Beam Brachytherapy
Radiation is delivered
directly where it is needed
A machine (for example,
a linear accelerator)
A pure radioactive source
that is always emitting radiation
Deposits energy throughout the patient The source is placed inside the patient

The patient attends. No radiotherapy is delivered, instead the patient is scanned,
and if necessary moulds are taken
The Radiotherapy Treatment Pathway
The patient is referred to the Radiotherapy
department
This is the Prescription.
A clinician annotates the scans using a planning system, indicating:• Where the individual beams of the Linac will go, • What dose will be delivered per day, and • How many times the patient will have to attend.
The patient attends the department for
one or more deliveries of radiotherapy.
This is an Attendance.
This is the Planning Appointment.

Details unique to the patient, such as name, date of birth, etc
Patient
The patients episode of care – normally a time period which may contain several types of treatment treating a singular disease
Episode
The attendance by the patient to a radiotherapy department for the delivery of one or more fractions of radiotherapy. Because the patient could be having more then one fraction delivered, this is not guaranteed to be unique per prescription
AttendanceA Prescription for a dose and fractionation of radiotherapy to be delivered to the patient.

Diagnosis of the diseasebeing treated
Diagnosis

Version 6 of the RTDS
Currently in public consultation for Version 6
• After consultation and review, will need to go to national body for approval
• Several changes, mostly around getting better clinical data
and improving provider readability at the point of export
• Currently planned for go-live in 2022
Contact the RTDS Helpdesk to request a copy of the current schema
• Consultation from the 16th November to the 18th December

System
The majority of RTDS comes from Record and Verify systems
![Page 22: The Radiotherapy Dataset · 2020. 11. 18. · Mosaiq. •Dataset documented and available on request 25 Public Health England25 OverviewPublic Health England Submissions –the Elekta](https://reader035.fdocuments.in/reader035/viewer/2022071415/6110d9a5843c466a3a3c8538/html5/thumbnails/22.jpg)
22
Further caveats
• Not all treatments need a plan, so not all treatments go on a planning system
• Not all radiotherapy delivering devices are connected to Record and Verify Systems
• For non-device delivered radiotherapy, or machines used infrequently or for low volumes,
Providers either enter data by hand on to the R+V, or submit the “other” format

35
Types of Applications
RTDS is currently used in a variety of ways.
• Immediate uses that change individual patient care
• Operational monitoring
• Research projects
• Processed and added to a patients cancer registration
These include:
![Page 36: The Radiotherapy Dataset · 2020. 11. 18. · Mosaiq. •Dataset documented and available on request 25 Public Health England25 OverviewPublic Health England Submissions –the Elekta](https://reader035.fdocuments.in/reader035/viewer/2022071415/6110d9a5843c466a3a3c8538/html5/thumbnails/36.jpg)
36
Immediate application (BARD)
The RTDS is used to support BARD,
Breast Screening After Radiotherapy Dataset
• Launched in 2018, BARD is a national database which records women who
have had radiotherapy to breast tissue before the age of 36.
• These patients are at increased risk of developing a second primary, and
BARD has been designed to ensuring screening is arranged at an appropriate time.
• At present BARD only records women with a lymphoma diagnosis

Operational Monitoring (CS2)
The RTDS is used to provide operational reporting to all
centres submitting.
Cancerstats 2 provides a variety of operational reporting,
and is updated on a weekly basis

Research projects
RTDS has also been used in a variety of research projects
• In most of the cases we will be showing, analytical work was done in house,
• however requests for the data can be made via the Office of Data Release

HERO pt 1 of 2
RTDS is contributing to HERO,
Health Economics in Radio-Oncology
• HERO is a project to benchmark costs for radiotherapy between different countries
• HERO is run by ESTRO, the European Society for Radiotherapy and Oncology

HERO pt 2 of 2
Examples of HERO data capture form
• RTDS data is being used to calculate the volumes of treatments being performed
• The granular per Trust capture of RTDS should contribute to the accuracy of the figures
• The English participation is being supported by the Royal College of Radiologists, the RCR

For English patients, RTDS data is also processed by
our Cancer Registration Officers and added to the
cancer registrations made by the Registry.
Cancer Registrations
The patients cancer registration will be
formed in part of the various datasets
received by the registry.

Simulacrum
RTDS is also being simulated in the Simulacrum
• Health Data Insight (HDI), in partnership with AstraZeneca and IQVIA,
have developed a synthetic dataset (the Simulacrum) to imitate some
of data held by NDRS, including the RTDS.
• As the data contains no real patient information, it can be used to analyse
cancer data without compromising patient confidentiality.
More information is available on the Cancerdata website (https://www.cancerdata.nhs.uk/simulacrum)
