Colorectal - Pathology

This is the site specific section for additional colorectal cancer specific data items to be recorded. These will be aligned within the schema to form a single report.

May be up to one occurrence per pathology report (0..1) 

Note the following data item has been retired from v5.0:

• Status Of Circumferential Excision Margin

  • this data item is now centralised in CORE [pCR1150], as this is relevant to many tumours

Longitudinal Margin Involved

Record whether the proximal or distal resection margins were involved. If the minimal distance from the cut margin is less than or equal to 1 mm the margin is considered ‘involved’.

Notes:

• this data item has a new name, previously ‘Positive Proximal or Distal Resection Margin’

• ‘8 – N/A - Not submitted by pathologist’ has been updated to match the RCPath Core data set

Distance to Circumferential Margin

Record the distance from the outer margin of the tumour to the closest non-peritonealised circumferential resection margin in mm.

Plane of Surgical Excision

This is the quality of the surgical excision as seen by the pathologist. This grades the resection on its worst plane.

Distance From Dentate Line

For abdominoperineal excision specimens only. Record the distance of the tumour from the dentate line in mm measured on the gross specimen.

Distance Beyond Muscularis Propria

Maximum distance of spread beyond muscularis propria in mm. If there is doubt about the sites of the muscularis propria estimate the distance as accurately as possible.

Response to Preoperative Therapy

If preoperative therapy was given what was the response.
