Abstract:
Purpose:To investigate the correlation between the expression of gene protein of c-fos,bcl-2 and gastric cancer and to provide the evidence of molecular pathology for grouping and early diagnosis.Methods:The expressions of gene-protein of c-fos,bcl-2 of the resected specimen of 54 patients with gastric carcinoma were detected by immunohistochemical method of S-P.All of the data were input into computer by system of Excel and SAS for statistical analysis.Results:The expressions of gene protein of c-fos,bcl-2 in intestinal type of gastric carcinoma were significantly higher than those in diffuse type (P=0.012, 0.0001, respectively).The expressions of gene protein of c-fos ,bcl-2 in the group of lymphaden metastasis were higher than that in the group of no lymphaden metastasis (c-fos 63.64%,54.55%;bcl-2 50.00%,27.27%), but no statistical significance.The expressions of c-fos , bcl-2 in atypical hyperplasia tissue nearby carcinoma and high differentiated carcinoma were stronger.Conclusions:The expressions of gene protein of c-fos,bcl-2 in intestinal type of gastric carcinoma were significantly higher than those in diffuse type.It showed that the pathogenesis of gastric carcinoma have difference between the intestinal type and diffuse type and it maybe provide proofs for gastric carcinoma grouping.The expression of c-fos,bcl-2 can be used as the molecular pathological symbols for early diagnosis.
