隆起型非典型上皮病变作为一种胃良、恶性交界性病变,无论在临床或病理组织学方面均酷似Ⅱa型高分化型管状腺癌,难以鉴别。此外,良性胃溃疡中出现幼稚非典型再生上皮时,常难与凹陷型早期胃癌相鉴别。为此,作者从这些不同病灶的生物学研究着手,应用酶抗体法对肿瘤标记物癌胚抗原(CEA)、糖类抗原19-9(CA19—9)进行研究。 As a type of borderline benign and malignant lesion of the stomach, the atypical epithelium of the uplift type is difficult to differentiate, regardless of clinical or histopathological features, similar to Type IIa highly differentiated tubular adenocarcinoma. In addition, when naive atypical regenerative epithelium occurs in benign gastric ulcer, it is often difficult to distinguish it from depressed type early-stage gastric cancer. To this end, the authors proceeded from the biological studies of these different lesions, using the enzyme antibody method to study the tumor marker carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9).
