Abstract

Endoscopic treatment of early oesophageal squamous cell carcinoma is widely accepted. ESD (Endoscopic Submucosal Dissection), which allows en bloc resection regardless of size, provides resected specimens that facilitate histological evaluation of curability. In the histological investigation, the determination of tumor depth, lymphovascular involvement, and lateral and vertical margins play a great role in the assessment of curability. The diagnosis of lymphovascular invasion, in particular, is enhanced by the addition of immunostaining. The long-term outcome of ESD is comparable to that of oesophagectomy, and ESD may be the first-line treatment for early-stage oesophageal cancer due to its fewer complications. Surveillance after curative resection is also imperative because oesophageal cancer is often characterized by the concept of field cancerization, which results in metachronous multiple primary lesions.

食道鳞状细胞癌内镜治疗的治愈标准
早期食道鳞状细胞癌的内镜治疗已被广泛接受。ESD(内镜下粘膜下剥离术)可进行不分大小的整体切除,其切除标本有助于组织学评估治愈率。在组织学检查中,确定肿瘤深度、淋巴管受累情况以及侧缘和纵缘对评估治愈率起着重要作用。尤其是淋巴管受侵的诊断,通过增加免疫染色可以得到加强。ESD的远期疗效与食道切除术相当,由于并发症较少,ESD可作为早期食道癌的一线治疗方法。根治性切除术后的监测也很重要,因为食道癌通常具有野外癌化概念的特征,这导致了多发性原发病灶的并发。
