Summary

AI Generated

A prospective study of 407 colorectal endoscopic mucosal resections of lesions ≥20mm with 5-year follow-up found an overall recurrence rate of 19.9%, with lesion size as the primary independent risk factor.

Overall recurrence rate was 19.9%, declining over time: 15.8% at 3 months, 7.4% at 12 months, 3.6% at 36 months, and 0% at 60 months
Logistic regression identified escalation in lesion size in multiples of 20mm as the only significant independent risk factor for recurrence (OR 1.98, p<0.001)
Larger lesions showed higher recurrence: 34.7% for lesions ≥60mm, 33.7% for 40-60mm lesions, and 12.8% for lesions ≤40mm
The overall complication rate was 6.1%, including 3 perforations, 17 bleeding events, and 3 cases of post-polypectomy syndrome
The authors concluded that 5-year surveillance is an adequate interval to evaluate EMR efficacy and safety in this population

Abstract

Introduction

Colorectal endoscopic mucosal resection (EMR) is associated with high recurrence rates, which requires a regular surveillance program by colonoscopy. Our aim was to study the 5-year follow-up of a population undergoing EMR and the risk factors associated with recurrence.

Aims & Methods

Prospective cohort study, single centre, including patients who underwent colorectal EMR of lesions ≥20mm with a minimum follow-up of 5 years, between 2009 and 2019. We analysed the lesions’ characteristics, as well as the recurrence rate, and logistic regression conducted for risk factors associated with recurrence.

Results

Included 407 EMR and patients were 58% male, with a mean age of 68.5±9.8 years. From our analysis: 65.8% of the lesions were 20-40mm, 21.4% 40-60mm and 12.8% were ≥60mm; 49.4% were sessile and 50,6% flat; 34.1% were localized in the right colon, 21.6% in the transverse colon, 15.5% in the left colon, and 28.7% in the rectum; 85.7% were granular and 14.3% non-granular. The mean SMSA score was 12.5±1.8. The overall recurrence rate was 19,9%, with rates and respective time of follow-up as follows: 15,8%, 7,4%, 3,6% and 0% at 3, 12, 36 and 60 months.
Evaluating the risk factors for recurrence, anal location (32.6% vs. 18.4%; p=0.02) and size of lesion: ≥60mm vs. 40-60mm vs. ≤40mm (34.7% vs. 33.7% vs. 12.8%; p<0.001) were statistically significant, but not with argon plasma therapy (23.3% vs. 18.1%; p=0.21) and non-granular morphology (19.0% vs. 20.3%; p=0.82). Logistic regression analysis revealed that only an escalation in size in multiples of 20mm had a significant risk of recurrence (OR 1.98; p<0.001). The global complication rate was 6.1%, including early complications (perforations, n=3) and late complications (bleeding, n=17 and post-polypectomy syndrome, n=3).

Conclusion

Despite the high overall recurrence rate, a 5-year surveillance has demonstrated to be an adequate time interval to evaluate the EMR’s efficacy and safety.
