早期食管癌内镜诊断新进展

Advances in endoscopic diagnosis of early esophageal cancer

食管癌是我国最常见的恶性肿瘤之一,其预后与疾病检出时的分期密切相关,早期食管癌预后很好,然而进展期食管癌预后却不容乐观.因此,疾病的早期发现至关重要.近年来,内镜技术得到了飞速发展,涌现了荧光内镜、共聚焦显微内镜、光学相干层析技术和电子染色成像技术诸如内镜窄带成像技术、智能电子分光比色技术、I-Scan技术等多种诊断方法.然而,在未来的几年里这些技术的临床应用价值尚待确定.本文就早期食管癌的内镜诊断进展作一综述.

Esophageal cancer is one of the most common malignancies in China. The prognosis of esopha- geal carcinoma is closely related to the stage of the disease at the time of detection. Patients with early lesions have an excellent prognosis, whereas those with more advanced stages of the disease usually have a poor prognosis. There- fore, the early detection of these lesions is of the greatest importance for treatment. Recently, many endoscopic methods have been developed, such as fluorescence endoscopy, confocal endos- copy, optical coherence tomography （OCT）, and electronic staining imaging technology which includes narrow band imaging （NBI）, Fujinon intelligent chromoendoscopy （FICE） and I-Scan. However, the clinical value of these techniques needs to be ascertained in the coming years. This paper reviews the progress of endoscopic diag- nosis of early esophageal cancer.
