Tumour perforation in colorectal cancer is the conjunction of an intestinal perforation and a colorectal tumour.
The Royal College of Pathologists Australia (RCPA) defines it as: perforation at the site of the tumour.[1]
Definitions
- The Royal College of Pathologists Australia (RCPA) defines tumour perforation as: perforation at the site of the tumour.[2]
- The College of American Pathologists protocol (version 4.3.1.0) cites Anwar et al.[3] and notes that: perforation proximal to the tumour is a poor prognosticator.
- Possible implication: perforation at the tumour and proximal to the tumour may not be that different.
- Banaszkiewicz et al. states that: the perforation site does not need to be at the anatomical site of the tumour.[4]
Note:
- A colorectal wall defect may be an artifact of extraction ("tissue abuse") rather than perforation.
- Artifact of extraction likely if all the following apply: (i) no inflammatory reaction is present, (ii) no cautery, and (iii) no perforation described in the OR report.
General
- Poor prognosticator.[3]
- Does not affect the (overall) stage; however, it been suggested that perforated colorectal carcinoma be considered stage IV.[5]
