Barrett's esophagus (BE) is the only known precursor to esophageal adenocarcinoma (EAC), a cancer associated with increasing incidence and poor survival. Early identification and effective treatment of BE-related neoplasia prior to the development of invasive adenocarcinoma are essential to limiting the morbidity and mortality associated with this cancer. In this review, we summarized the recent evidence guiding endoscopic eradication therapies (EET) for neoplastic BE.
New sampling technologies and the application of artificial intelligence (AI) systems have potential to revolutionize early neoplasia detection in BE. EET for BE are safe and effective in achieving complete eradication of intestinal metaplasia (CE-IM) and reducing the progression to EAC, a practice endorsed by all GI society guidelines. EET should be considered in patients with high-grade dysplasia (HGD), intramucosal carcinoma (IMC), and select cases with low-grade dysplasia (LGD). The increasing use of endoscopic submucosal dissection (ESD) in the West may allow EET of select cases with submucosal EAC. Post-EET surveillance strategies will continue to evolve as knowledge of specific risk factors and long-term neoplasia recurrence rates improve. In the last decade, major advancements in EET for neoplastic BE have been achieved. These now represent the standard of care in the management of BE-related dysplasia and intramucosal cancer.
巴雷特食管(BE)是食管腺癌(EAC)唯一已知的前体,EAC 发病率不断上升,且预后较差。在浸润性腺癌发生之前,早期识别和有效治疗 BE 相关肿瘤,对于限制与这种癌症相关的发病率和死亡率至关重要。在这篇综述中,我们总结了指导 BE 相关肿瘤内镜下消除治疗(EET)的最新证据。
新的采样技术和人工智能(AI)系统的应用有可能彻底改变 BE 早期肿瘤的检测。EET 治疗 BE 安全有效,可实现肠上皮化生(CE-IM)的完全消除,并降低 EAC 的进展风险,所有胃肠病学会指南都认可这一做法。EET 应考虑用于高级别异型增生(HGD)、黏膜内癌(IMC)和少数低级别异型增生(LGD)患者。在西方,内镜黏膜下剥离术(ESD)的应用越来越广泛,可能允许对少数黏膜下 EAC 进行 EET。随着对特定危险因素和长期肿瘤复发率的了解不断提高,EET 后的监测策略将继续发展。在过去十年中,BE 相关肿瘤的 EET 取得了重大进展。这些现在是 BE 相关异型增生和黏膜内癌管理的标准治疗方法。
