NBI-ME对早期食管鳞状细胞癌及癌前病变的诊断价值及BNIP3/Beclin-1在食管癌发生过程中表达的研究
发布时间:2021-01-31 14:13
食管癌是人类常见的消化道肿瘤,发生淋巴结转移较早,多数患者确诊时已为中晚期,预后极差,5年生存率不足20%,而局限于粘膜层及粘膜下层的早期食管癌治疗后5年生存率可超过95%,可见食管癌早诊断、早治疗意义重大。但是早期食管癌病变不明显,诊断较困难,普通白光内镜下极易漏诊,漏诊率可高达40%。随着内镜技术的发展,应用卢戈氏碘染色结合粉红色征(lugol chromoendoscopy with pink-color sign,LCE-PS)的方法大大提高了早期食管癌的检出率,但是碘染色存在很多弊端(如引起患者胸骨后疼痛、烧心等),而窄带成像技术(narrow band imaging,NBI)则避免了化学染料带来的问题,而且能够增加粘膜上皮和粘膜下血管的对比度和清晰度。日本学者井上晴洋应用放大内镜(magnifying endoscopy,ME)通过观察食管上皮乳头内毛细血管袢(intrapapillary capillary loops,IPCL))的变化来判断食管病变的良恶性、病变的范围及浸润深度,并最早提出了IPCL分型。目前应用NBI-ME观察IPCL形态已成为早期食管癌及癌前病变...
