• Frequency counts of cancer patients receiving radiotherapy, who were resident in England, and began treatment with radiotherapy between 1st April 2016 and 31st March 2017. All data is derived from the patient-level Radiotherapy Treatment Dataset (RTDS) data recorded by National Cancer Registration and Analysis Service (NCRAS).
• Data is aggregated using anatomical site groups according to the International Classification of Diseases (ICD) ICD-10 codes, except where otherwise stated. Groupings are identified in tab: ‘Reference – tumour groupings.’ Data is further aggregated by age at treatment start date (presented as 5 year age bands) and sex (male/female).
• Treatments are categorised by modality or method of treatment, as (1) external beam radiotherapy (EBRT or Teletherapy) and (2) internal brachytherapy
Whenever it is possible and practicable to do so, data released by PHE will be anonymous and made available under an Open Government License. To render the data anonymous it must be stripped of direct identifiers and privacy by design methods applied in line with the rules layed out in the ISB Anonymisation Standard for Publishing Health and Social Care Data Specification (2013).
