Abstract
Background
Malignant colorectal polyps (MCRP) have become a major challenge in the field of coloproctology from diagnosis to full treatment. One important facet of the challenge is the histopathological staging of the lesion and identifying various prognostic parameters. The primary aim of this study was to find the interobserver variation amongst 4 experienced gastrointestinal pathologists when assessing important parameters and staging systems (Haggitt, Kikuchi and Ueno) in MCRPs.
Methods
Four experienced gastrointestinal pathologists independently assessed 56 cases of MCRP, and each pathologist completed a pro forma for each case. The results were collated and statistically analysed.
Results
There was a significant variation in the assessments using the various published staging systems agreed upon on important prognostic parameters.
Conclusions
None of the staging systems used is suitable for all polyp types or has good reproducibility. There is an urgent need to make pathologists’ assessment of MCRPs easier and more reproducible.
