Pathology reporting of pelvic exenteration specimens for locally recurrent rectal cancer

Abstract

Introduction: Reporting of pelvic exenteration specimens for locally recurrent rectal cancer (LRRC) can be challenging for structured pathological analysis and currently, there is a lack of specific guidelines. The aim of this study was to assess the quality of pathology reporting in a cohort of patients who underwent pelvic exenteration for LRRC in a high-volume tertiary unit.

Materials and methods: In a retrospective analysis of histopathology reports of consecutive patients who underwent pelvic exenteration for LRRC from 1996 to 2018, the quality of pathology reporting was assessed using the Structure Reporting Protocol for Colorectal Cancer. The primary endpoint was the completeness of pathology reporting, secondary endpoints were the association between the reporting style (narrative versus synoptic), reporting period (the first half versus the second half), as well as the activity of the pathologists with the completeness of pathology reporting.

Results: 221 patients who underwent pelvic exenteration for LRRC were included into the study. There was a high variability in completeness of pathology reporting within the cohort, ranging from 9.5% to 100%. Notably, microscopic clearance was reported in only 92.4% of the reports. Overall, a significantly higher rate of completeness was observed in synoptic reports when compared to narrative reports and in more recent compared to earlier reports. There was no significant association between the activity of pathologists and the completeness of reporting.

Conclusions: This study shows a significant variability in the quality of reporting in pelvic exenteration for LRRC. The use of synoptic reporting clearly resulted in more complete reports.
