Differentiated adenocarcinoma of the stomach is classified into gastric or intestinal phenotypes based on mucus expression. Recent advances in mucin histochemistry and immunohistochemistry have highlighted the importance of such a distinction, and it is important clinically to distinguish between gastric- and intestinal-type differentiated adenocarcinoma. However, a clinical and pathological diagnosis of this type is often difficult in early gastric cancer because of histological similarities between a hyperplastic epithelium and low-grade atypia. Furthermore, determining tumor margins is often difficult, even with extensive preoperative examination. It is therefore critical to consider these diagnostic difficulties and different biological behaviors with high malignant potential when treating patients with gastric-type differentiated adenocarcinoma.
胃的肠型分化腺癌根据黏液表达分为胃型或肠型。黏液组织化学和免疫组织化学的最新进展突出了这种区分的重要性,临床上区分胃型和肠型分化腺癌很重要。然而,由于增生上皮和低级别异型增生之间的组织学相似性,早期胃癌的这种类型的临床和病理诊断往往很困难。此外,即使进行广泛的术前检查,确定肿瘤边界也常常很困难。因此,在治疗胃型分化腺癌患者时,必须考虑到这些诊断困难和具有高恶性潜能的不同生物学行为。
