        Objectives: Glutsthione S-Transferases (GSTs) are a family of isoenzymes which catalyse the conjugation of glutathione to a variety of electrophilic compounds which include carcinogens and cytotoxic drugs. These enzymes probably form part of an inherent, protective mechanism against the development of tumors. There is also evidence to suggest s role for GST in drug resistance in cancer chemotherapy. Three classes of cytosolic GST isoenzymes exist in man. These are identified as basic(a), neutral(μ), acidic(π) GST. GSTπ has been studied recently because of its high level in biliary or colon carcinoma. To assess the relation of the expression of GSTπ with malignant index on human gastric carcinoma, this study was designed. Methods: Immunohistochemical study for GSTπ was performed in paraffin sections of 85 primary gastric carcinomas. Results: 1) Strong positive reaction for GST was observed mainly in the nuclei and cytoplasms of tumor cells and normal mucosal epithelium around cancer nest revealed weak positive reaction. 2) The positivity of GSTπ in gastric carcinoma was 94.1%. By the histological differentiation, the positivity was 84.2% in well-differentiated adenocarcinoma, 100% in moderately-differentiated adenocarcinoma, 100% in poorly-differentiated adenocarcinoma, 93.89o in mucinous adenocarcinoma, 90% in signet-ring cell carcinoma. Moderately-differentiated adenocarcinoma and poorly-differentiated adenocarcinoma revealed the most high positivity ratio. 3) Positivity of GSTπ in cancer nest had a increased trend in poorly-differentiated than well-differentiated adenocarcinoma. Conclusion: The results suggest that GSTπ may be a useful tumor marker of human gastric carcinoma.
