            <strong>[[食管腺癌]]</strong>（<strong>[[Esophageal Adenocarcinoma]]</strong>）是起源于[[食管]]黏膜[[腺上皮]]的恶性肿瘤，主要发生于食管下1/3段及<strong>[[胃食管结合部]]</strong>（[[GEJ]]）。与[[食管鳞癌]]不同，其发病与<strong>[[胃食管反流病]]</strong>（[[GERD]]）及由此诱发的<strong>[[巴雷特食管]]</strong>（[[Barrett's Esophagus]]）密切相关。[[食管腺癌]]具有高度的[[分子异质性]]，常伴有<strong>[[ERBB2]]</strong>（[[HER2]]）扩增、<strong>[[VEGFA]]</strong>过表达及<strong>[[CLDN18.2]]</strong>异常表达。随着[[精准医疗]]的发展，治疗模式已由传统化疗演变为包括[[免疫检查点抑制剂]]（如[[PD-1单抗]]）及新型[[抗体偶联药物]]（[[ADC]]）在内的多模态综合治疗。
