The audit receives data on patients from Wales centrally from the Cancer Network Information System Cymru (CaNISC). These records are linked to the Patient Episode Data Wales (PEDW) to obtain further information on patient care and follow-up (the equivalent of Hospital Episode Statistic data for English patients).

The audit does not collect or analyse data for patients who were diagnosed with oesophago-gastric cancer in Scotland or Northern Ireland. The audit reports only patients from England and Wales. If you are representing a devolved nation and wish to submit data to NOGCA, please contact HQIP who will be able to advise.

We link patient level information to the following external data sources:

• Hospital Episode Statistics (HES)
• Office of National Statistics (ONS)
• National Radiotherapy Dataset (RTDS)
• Systemic Anti-Cancer Therapy (SACT, the chemotherapy dataset)
• Intensive Care National Audit & Research Centre dataset (ICNARC)
• Patient Episode Database for Wales (PEDW)

We use your NHS number to link your information to other secure information sources, such as the National Radiotherapy Dataset. This linked information tells us more about your treatment – for example, if you had an unplanned return to hospital.

The linked information from you and other patients across England and Wales is given to The Royal College of Surgeons (RCS) to analyse and use in the audit reports. The information is anonymised so you cannot be identified.

We may also provide NHS numbers of deceased patients to hospitals so they can check the information they have entered in the audit database is correct.

Improvements in cancer care have been made since the audit began but it is important that this progress continues. For example, survival rates after surgery have improved year on year.

Audits are most effective when information from as many patients as possible is collected. So every patient is valuable to the audit.

The more patients we have information about, the more accurate our results are likely to be.

Only information from your hospital notes is used in the audit. The hospital enters your treatment information and NHS number onto a secure computer database at NHS Digital.

We provide a list of useful external websites of cancer charities and other organisations in the Links section of the website.
