摘要
直肠癌是全球高发癌症,其发病人数、死亡人数在各癌种中均处于高位.目前直肠癌的治疗方式主要为手术切除或行新辅助治疗后再行手术切除.然而因直肠癌解剖位置不同而采取不同治疗方式可能导致复发率高、患者预后差.因此,准确的术前评估对于确定治疗方式尤为重要.直肠癌环周切缘(Circumferential Resection Margin,CRM)状态是术前评估的关键因素.本文综合分析直肠腔内超声、CT、MRI等影像学检查方法,介绍这些检查手段及其新技术、新方法评估直肠癌CRM的应用进展,以期为临床选择合适的治疗方式提供依据.
Abstract
Rectal cancer is a high incidence cancer in the world,and its morbidity and mortality are high in all cancers.At present,the treatment of rectal cancer is mainly surgical resection or surgical resection after neoadjuvant treatment.However,different treatment methods may lead to high recurrence rate and poor prognosis due to different anatomical locations of rectal cancer.Therefore,accurate preoperative evaluation is particularly important for determining the treatment mode.Circumferential resection margin(CRM)of rectal cancer is a key factor for preoperative evaluation.This paper comprehensively analyzed the imaging examination methods such as intrarectal ultrasound,CT,MRI,and introduced the application progress of these examination methods and their new technologies and methods to evaluate the CRM of rectal cancer,aims to provide a basis for selecting appropriate treatment methods in clinical practice.
