由于贲门癌发生在食管－胃交界处１～２ｃｍ的特殊部位，早期症状不典型，其组织学类型多数为恶性程度较高的腺癌类恶性肿瘤，患者在出现有进食梗噎症时病期多数已发展为中晚期。 目前贲门癌发病率有呈上升趋势，行贲门癌根治性切除是目前唯一有可能将贲门癌治愈的首选治疗手段 Since cardiac cancer occurs at a special site of 1 to 2 cm at the esophageal-gastric junction, the early symptoms are not typical. Most of histological types are adenocarcinoma malignancies with a high degree of malignancy, and patients have a stage of eating sputum. Most have developed into the middle and late stages. At present, the incidence of cardiac cancer is on the rise, and radical resection of cardia cancer is currently the only treatment method that may cure cardiac cancer.
