| Popis: | Objective: To investigate the relation of liver-type fatty-acid-binding protein (L-FABP) expression to the clinicopathological characteristics or the fatty acid synthase status of gastric cancers. Methods: L-FABP expression was examined immunohistochemically in 667 gastric cancers, 60 gastric adenomas, and non-neoplastic epithelium contiguous with cancer tissue including normal foveolae, intestinal metaplasia, regenerative epithelium, and gastric glands. Results: L-FABP was positive in 38% (high in 9% and low in 29%) of gastric cancers. It occurred preferentially in papillary carcinomas, female cases, and in patients under 50 years. In gastric cancers, L-FABP expression had no intimate correlation with the FAS status, and it showed no relationship with prognosis and cancer progression as indicated by venous and lymphatic permeation, and nodal or hepatic metastasis. Gastric tubular adenomas mainly revealed low (22%) expression of L-FABP while intestinal metaplasia showed the most frequent (>95%) and intense L-FABP expression. Normal foveolae and gastric glands showed no or less L-FABP expression. Conclusions: L-FABP is highly and intensely expressed in metaplasia and in a subset of gastric adenocarcinomas, without association with progression, prognosis and fatty acid synthase status of the carcinoma. |
