- BACKGROUND
Survivin, a novel antiapoptotic gene has been linked with tumor development and progression in various human carcinomas including gastric carcinomas. The aim of this study was to evaluate the expression of survivin in gastric carcinoma and its correlation with tumor cell proliferation and apoptosis. METHODS: Expression of survivin was evaluated immunohistochemically in 84 surgically resected gastric carcinomas. Tumor cell apoptosis was evaluated with terminal deoxynucleotidyl transferase (TdT) mediated deoxyuridine triphosphate (dUTP) nick-end labeling (TUNEL), and Ki-67 immunostaining was used for evaluation of tumor cell proliferation. RESULTS: Expression of survivin was noted in 53.6% of the gastric carcinomas, and was significantly associated with depth of invasion, status of lymph node metastasis or tumor stage (p=0.022, 0.034, 0.040, respectively). There was an inverse correlation between survivin expression and apoptotic index (p=0.015). But there was no significant correlation between survivin expression and Ki-67 labeling index (p=0.430). CONCLUSIONS: These results suggest that survivin expression may contribute to tumor development and progression by inhibiting apoptosis in human gastric carcinoma.

- The purpose of this study is to obtain the clinicopathological characteristics of replication error-positive (RER ) gastric adenocarcinoma in Korean, and to identify the significance of RER in adenoma stage of gastric carcinogenesis. Microsatellite instability was examined at D2S71, D2S119, D3S1067, D6S87, D11S905, DM, AR, VWF, HPRT, and BAT-26 loci. Frameshift mutation of BAX gene was analyzed in RER tumors. Normal and tumor DNA of 76 cases of gastric carcinoma and 25 cases of adenoma were examined. RER was found in 8 of 76 cases (10.5%), and it was more frequently found in adenocarcinoma of female (17.7%) than those of male (4.8%).
The frequency of RER was not different between the histologic types, age of the patient, anatomical location of the carcinoma, and the stage. The RER found in adenoma suggests that RER contributes to the malignant transformation early in the adenoma stage of the gastric carcinogenesis. None of the RER tumors revealed frameshift mutation of the BAX gene.
