Abstract

BACKGROUND

Lymphatic invasion, vascular invasion, and perineural invasion are prognostic factors for colon cancer. However, the prognostic significance of those factors according to the location of permeation (intramural and extramural invasion) in stage II colon cancer is still unclear.

OBJECTIVE

This study aimed to clarify whether the location of lymphatic invasion, vascular invasion, and perineural invasion could affect the survival of patients with stage II colon cancer.

DESIGN

This was a retrospective cohort study.

SETTINGS

This study took place at a university teaching hospital.

PATIENTS

A total of 1130 patients with stage II colon cancers who underwent radical surgery at the Seoul National University Hospital between July 2003 and December 2015 were included.

MAIN OUTCOME MEASURES

Patients were classified according to the location of lymphatic invasion, vascular invasion, and perineural invasion. Survival outcomes were compared among those without invasion and those with intramural and extramural invasion. Primary end point is overall survival and secondary end point is disease-free survival.

RESULTS

Disease-free survival and overall survival of patients with extramural invasion were worse than those of patients without invasion and those with intramural invasion. Multivariate analysis for survival outcomes confirmed that extramural invasion was a significant independent prognostic factor. However, both disease-free survival and overall survival were not significantly different between patients without invasion and those with intramural invasion.

LIMITATIONS

This study was limited by its retrospective design.

CONCLUSIONS

Extramural invasion was associated with worse prognosis in stage II colon cancer, but intramural invasion was not. Therefore, pathologic reports about the location of lymphatic invasion, vascular invasion, and perineural invasion might be helpful for predicting prognosis and for determining the need of adjuvant chemotherapy in stage II colon cancers.

IMPACTO PRONSTICO DE LA INVASION EXTRAMURAL LINFTICA, VASCULAR Y PERINEURAL EN EL CNCER DE COLON ESTADO II ESTUDIO COMPARATIVO CON RELACIN A LA INVASIN INTRAMURAL: ANTECEDENTES:La invasión linfática, vascular y perineural son factores pronósticos para el cáncer de colon. Sin embargo, la importancia pronóstica de estos factores de acuerdo con la ubicación de la permeabilidad (invasión intramural y extramural) del cáncer de colon en estadío II aún no está aclarada.OBJETIVO:El presente estudio tiene por objetivo, el de aclarar si la localización de la invasión linfática, vascular y perineural podría afectar la sobrevida en los pacientes con cáncer de colon en estadío II.DISEÑO:Estudio de cohortes de caracter retrospectivo.AJUSTES:Nuestro estudio se llevó a cabo en un hospital docente universitario.PACIENTES:Se incluyeron un total de 1130 pacientes diagnosticados con cáncer de colon en estadío II, los cuales fueron sometidos a cirugía radical en el Hospital Universitario Nacional de Seúl, entre julio de 2003 y diciembre de 2015.PRINCIPALES MEDIDAS DE RESULTADO:Los pacientes fueron clasificados según la localización de la invasión linfática, vascular y perineural.

El análisis multivariado de los resultados de la sobrevida confirmaron que la invasión extramural es un factor pronóstico independiente muy significativo. Sin embargo, tanto la sobrevida libre de enfermedad, como la sobrevida global no fueron significativamente diferentes entre los pacientes sin invasión y aquellos con invasión intramural.LIMITACIONES:Estudio limitado por su diseño con caracter retrospectivo.CONCLUSIONES:La invasión extramural fué asociada con un peor pronóstico en el cáncer de colon en estadío II, pero la invasión intramural no lo fué. Por tanto, los informes anatomopatológicos sobre la ubicación de la invasión linfática, vascular y perineural, podrían ser útiles para predecir el pronóstico y determinar el menester de la quimioterapia adyuvante en los cánceres de colon en estadío II.

摘要

背景

淋巴管浸润、血管浸润和神经周围浸润是结肠癌的预后因素。然而,这些因素在 II 期结肠癌中根据渗透位置(壁内和壁外浸润)的预后意义仍不清楚。

目的

本研究旨在阐明淋巴管浸润、血管浸润和神经周围浸润的位置是否会影响 II 期结肠癌患者的生存。

设计

这是一项回顾性队列研究。

地点

这项研究在一所大学教学医院进行。

患者

共纳入 2003 年 7 月至 2015 年 12 月期间在首尔国立大学医院接受根治性手术的 1130 例 II 期结肠癌患者。

主要观察指标

根据淋巴管浸润、血管浸润和神经周围浸润的位置对患者进行分类。比较无浸润、壁内浸润和壁外浸润患者的生存结局。主要终点是总生存期,次要终点是无病生存期。

结果

壁外浸润患者的无病生存期和总生存期均差于无浸润和壁内浸润患者。多变量生存分析证实,壁外浸润是独立的预后不良因素。然而,无浸润和壁内浸润患者的无病生存期和总生存期无显著差异。

局限性

本研究受限于回顾性设计。

结论

壁外浸润与 II 期结肠癌的预后较差相关,但壁内浸润则不然。因此,淋巴管浸润、血管浸润和神经周围浸润的位置报告可能有助于预测预后,并确定 II 期结肠癌是否需要辅助化疗。详见视频摘要,网址:http://links.lww.com/DCR/B939 。
