Adverse histological features in malignant colorectal polyps: a contemporary series of 239 cases

Abstract

AIMS: Screening colonoscopy has led to more colorectal carcinomas presenting at an early stage potentially curable by endoscopic resection. In this study, we examined the clinical and histological features of a contemporary series of malignant colorectal polyps (MCPs) with subsequent surgical resection. METHODS: We conducted a retrospective study on a consecutive series of MCPs from 239 patients, predominantly males (57.7%) with a median age of 66 years, and assessed histological parameters associated with residual disease on the surgical specimens. RESULTS: Median MCP size was 18.6 mm, with 23.1% polyps measuring ≤10 mm. From the 140 surgical resection specimens, residual disease was identi..
