Version No: 1.4
Subject: National Cancer Data Set - Change to Excision Margin
Type of Change: Change to Excision Margin codes
Effective Date: 1 January 2004
Reason for Change: The change was proposed as a result of analysis of the Royal College of Pathology data sets and approved by the Cancer Data Group.

Background:

The National Cancer Data Set Project, run by the NHS Information Authority, has produced a set of data items relating to the diagnosis and management of cancer.

The purpose of the National Cancer Minimum Data Set is to advise organisations within the National Health Service on a transferable set of data. These data will meet the needs of clinical audit, assist in the generation of National Performance Indicators and will allow outcome assessment.

Data Standards to support parts of the National Cancer Data Set have been released in earlier DSCNs.

More information about the project and the Data Set can be found at:

This DSCN updates NHS Data Standards to support the changes to the codes for Excision Margin.Summary of changes:
