Which patients are included in the audit?

The audit includes all primary diagnoses of bowel cancer within the current report period. Included patients must be:

• Aged 18 or older at the date of diagnosis
• Diagnosed in the audit period (April-March)
• Diagnosed with colorectal cancer for the first time, with one of the following ICD10 codes:

o C18 Malignant neoplasm of colon
o C19 Malignant neoplasm of rectosigmoid junction
o C20 Malignant neoplasm of rectum

A few data items are now collected on associated recurrent cancers in the non-primary record. The original primary diagnosis must be recorded in CAP for a recurrent cancer to be submitted.
