ABSTRACT
BACKGROUND:
The aim of this study is to elucidate the relationship between the CD44s and CD44v6 expression level and the biological characteristics of a gastric carcinoma.METHODS:
CD44s and CD44v6 expression was investigated in 56 gastric carcinomas, 18 dysplasias, and 22 normal mucosae by immunohischemical staining.RESULTS:
The CD44s and CD44v6 expression rates in gastric carcinomas, dysplasia, and normal mucosae were 80.3% and 83.9%, 72.2% and 77.8%, and 13.6% and 4.5%, respectively. Statistical analysis showed significant difference after comparing a gastric carcinomas and dysplasia to the normal mucosae (p<0.001). The CD44s and CD44v6 expression rates in the cases with invasion to the muscle proper and serosa were 60.7% and 57.1%, and 82.4% and 88.2%, respectively. Both showed a significant statistical difference compared to the expression rates in the cases with invasion to the mucosae and submucosae. The CD44s and CD44v6 expression rates in gastric carcinomas with a lymph node metastasis showed a statistically significant difference compared to those without a lymph node metastasis (p<0.001 and p<0.01, respectively). CD44s and CD44v6 were also expressed in the normal basal cells around gastric carcinomas.CONCLUSIONS:
The CD44s and CD44v6 expression showed a significant relationship with gastric carcinogenesis, toward an aggressive biologic behavior.
