Abstract
PDF Background Overexpression of heat shock protein 70 (HSP70) has been observed in many types of cancer including gastric adenocarcinomas, although the exact role of HSP70 in carcinogenesis remains unclear.
Methods The study analyzed a total of 458 radical gastrectomy specimens which were immunohistochemically stained with HSP70, p53, and Ki-67 antibodies.
Results The study determined that the expression of HSP70 was significantly increased in early gastric cancer (EGC) compared to advanced gastric cancer (p<0.001). The HSP70 expression was correlated with well-differentiated tumor type, intestinal type of Lauren classification and the lower pT and pN stage. Negative expression of Ki-67 and p53 expression was associated with poor prognosis. The study did not find any correlation between HSP70 and p53 expression. The study determined that HSP70 expression in the EGC subgroup was associated with a poor prognosis (p=0.009), as well as negative Ki-67 expression (p=0.006), but was not associated with p53. Based on multivariate analysis, HSP70 expression (p=0.024), negative expression of Ki-67, invasion depth and lymph node metastasis were determined to be independent prognostic markers.
Conclusions HSP70 is expressed in the early stages of gastric adenocarcinoma. In EGC, HSP70 is a poor independent prognostic marker and is correlated with a low proliferation index.

Abstract
PDF
- A gastric inverted hyperplastic polyp is characterized by downward growth of the hyperplastic mucosal components into the submucosa. Lesions are composed of hyperplastic foveolar-type glands, and sometimes coexist with gastritis cystica profunda (GCP). Adenocarcinoma frequen- tly can coexist, but the relationship is not clear. A 71-year-old male was admitted to hospital because of dyspepsia for one month. He underwent a wedge resection of the stomach, after endoscopic biopsies. The gross finding showed a slightly elevated papillary lesion with central depression. Microscopically, the elevated lesion was composed of hyperplastic fundic glands and foveolar cells, and the central depressed lesion showed a nodular inverted proliferation of normal appearing gastric epithelium and glands in the submucosa. An additional proximal gastrectomy specimen exhibited marked GCP and a minute adenocarcinoma at the proximal margin with p53 protein overexpression.

Abstract
PDF
- A 56-year-old man received subtotal gastrectomy for an early gastric carcinoma type IIa+IIc with submucosal invasion. The tumor was made up of mixed papillo-tubular adenocarcinoma and solid carcinomatous portion, the latter comprising approximately four-fifths of the total tumor mass. The solid portion was confined within the submucosa and revealed a mixture of trabecular, compact and pelioid patterns of large polyhedra cells, resembling hepatocellular carcinoma of the liver(Edmondson-Steiner grade 2). Sinusoid-like vascular stroma of classical trabecular hepatocellular carcinoma intervened the tumor cell nests but was not associated with endothelial-cell lining. Immunohistochemical stainings with alpha-fetoprotein and alpha1-antitrypsin gave a strong reactivity in those areas of hepatoid differentiation and in the adjacent minute portion of adenocarcinoma. The findings suggest that a portion of gastric carcinoma may transdifferentiate into cells with hepatoid features along the line of endodermal lineage.
