Abstract

BACKGROUND

Recommendations regarding management of colorectal dysplasia in the setting of IBD continue to evolve.

OBJECTIVE

This study aimed to determine the rate of progression from dysplasia to adenocarcinoma, specifically focusing on the differences in unifocal and multifocal low-grade dysplasia and dysplasia found on random biopsy versus targeted biopsies.

DESIGN

This is a retrospective review.

SETTING

This study was conducted at an IBD referral center.

PATIENTS

All adult patients (≥18 years of age) with a known diagnosis of either ulcerative colitis or Crohn's disease, who underwent a surveillance colonoscopy between January 1, 2010 and January 1, 2019, were selected.

MAIN OUTCOMES MEASURES

The primary outcomes measured were the progression of dysplasia and the risk factors for progression.

RESULTS

A total of 23,751 surveillance colonoscopies were performed among 12,289 patients between January 1, 2010 and January 1, 2019. The mean age at colonoscopy was 52.1 years (SD 16.9 years), 307 patients (2.5%) had a history of primary sclerosing cholangitis, and 3887 (3.15%) had a family history of colorectal cancer. There was a total of 668 patients (5.4%) with low-grade dysplasia, 76 patients (0.62%) with high-grade dysplasia, and 68 patients (0.55%) with adenocarcinoma in the series. The 1-, 2-, and 5-year cumulative incidence rate of progressing from low-grade dysplasia to high-grade dysplasia were 1.6%, 4.8%, and 7.8%. The 1- and 2-year cumulative incidence rates of progressing from low-grade dysplasia to adenocarcinoma were 0.7% and 1.6%. There were no significant differences in unifocal and multifocal progression. Primary sclerosing cholangitis, ulcerative colitis, male sex, and advanced age were all found to be significant risk factors for neoplasia on multivariable analysis.

LIMITATIONS

A retrospective database was a source of information.

CONCLUSION

Progression of low-grade dysplasia to adenocarcinoma, regardless of its being unifocal or multifocal, remains very low in the setting of adequate surveillance and medical management. The presence of multifocal low-grade dysplasia should not change the decision making to pursue ongoing endoscopic surveillance versus proctocolectomy. Patients who had primary sclerosing cholangitis with dysplasia found on random biopsies may be at highest risk for dysplasia progression. See Video Abstract at http://links.lww.com/DCR/A649.

EL DESENLACE DE LA DISPLASIA DE BAJO GRADO UNIFOCAL VERSUS MULTIFOCAL DURANTE LA COLONOSCOPIA EN PACIENTES CON ENFERMEDAD INFLAMATORIA INTESTINAL

La edad media en el momento de la colonoscopia fue de 52,1 años (DE 16,9 años), 307 pacientes (2,5%) tenían antecedentes de colangitis esclerosante primaria y 3887 (3,15%) tenían antecedentes familiares de cáncer colorrectal. Hubo un total de 668 pacientes (5,4%) con displasia de bajo grado, 76 pacientes (0,62%) con displasia de alto grado y 68 pacientes (0,55%) con adenocarcinoma en la serie. La tasa de incidencia acumulada de 1, 2, 5 años de progresión de displasia de bajo grado a displasia de alto grado fue del 1,6%, 4,8% y 7,8%. Las tasas de incidencia acumulada de 1 y 2 años de progresión de displasia de bajo grado a adenocarcinoma fueron 0,7% y 1,6%, respectivamente. No hubo diferencias significativas en la progresión unifocal y multifocal. Se encontró que la colangitis esclerosante primaria, la colitis ulcerosa, el sexo masculino y la edad avanzada eran factores de riesgo significativos de neoplasia en el análisis multivariable.LIMITACIONES:Base de datos retrospectiva.CONCLUSIÓN:La progresión de la displasia de bajo grado a adenocarcinoma, independientemente de que sea unifocal o multifocal, sigue siendo muy baja en el contexto de una vigilancia y un tratamiento médico adecuados. La presencia de displasia multifocal de bajo grado no debería cambiar la toma de decisión para continuar con vigilancia endoscópica continua o realizar la proctocolectomía. Los pacientes con colangitis esclerosante primaria y displasia encontrada en biopsias aleatorias pueden tener una mayor progresión de la displasia.

摘要

背景

关于炎症性肠病背景下结直肠异型增生管理的建议仍在不断发展。

目的

本研究旨在确定异型增生进展为腺癌的比率,特别是关注低级别异型增生的单灶和多灶性以及随机活检与靶向活检中发现的异型增生之间的差异。

设计

这是一项回顾性研究。

地点

本研究在炎症性肠病转诊中心进行。

患者

所有已知患有溃疡性结肠炎或克罗恩病的成年患者(≥18 岁),在 2010 年 1 月 1 日至 2019 年 1 月 1 日期间接受了监测结肠镜检查。

主要结局测量

主要结局指标是异型增生的进展和进展的危险因素。

结果

在 2010 年 1 月 1 日至 2019 年 1 月 1 日期间,对 12289 名患者进行了 23751 次监测结肠镜检查。结肠镜检查时的平均年龄为 52.1 岁(标准差 16.9 岁),307 名患者(2.5%)患有原发性硬化性胆管炎,3887 名患者(3.15%)有结直肠癌家族史。该系列中共有 668 名(5.4%)患者有低级别异型增生,76 名(0.62%)患者有高级别异型增生,68 名(0.55%)患者有腺癌。低级别异型增生进展为高级别异型增生的 1 年、2 年和 5 年累积发生率分别为 1.6%、4.8%和 7.8%。低级别异型增生进展为腺癌的 1 年和 2 年累积发生率分别为 0.7%和 1.6%。单灶和多灶进展无显著差异。原发性硬化性胆管炎、溃疡性结肠炎、男性和高龄均为多变量分析中肿瘤的显著危险因素。

局限性

回顾性数据库是信息的来源。

结论

在充分的监测和医疗管理下,低级别异型增生进展为腺癌,无论其为单灶性还是多灶性,仍然非常低。存在多灶性低级别异型增生不应改变继续进行内镜监测与直肠结肠切除术的决策。在随机活检中发现异型增生的原发性硬化性胆管炎患者可能面临最高的异型增生进展风险。
