目的:探讨 E钙粘附素( E C D) 表达与胃癌生物学行为的关系。方法:采用免疫组化染色方法检测80 例胃癌组织 E C D 的表达情况。结果:正常胃粘膜呈 E C D 保留表达,863 % (69/80) 的胃癌 E C D 表达减弱或消失; E C D 表达减弱与胃癌浸润型生长及分化较差密切相关( P< 001) ,而与胃癌浸润深度、淋巴结转移、静脉、淋巴管润浸无关( P> 005) 。结论: E C D 的表达可能决定着胃癌的生长方式和分化程度,而与胃癌侵袭转移潜能无关。
Objective: To investigate the relationship between Ecadherin (EC D) expression and biological behavior of gastric cancer. Methods: Immunohistochemical staining was used to detect the expression of EC D in 80 cases of gastric cancer. RESULTS: Normal gastric mucosa was preserved with E C D expression, and 86 3 % (69/80) of gastric cancer E C D expression was weakened or disappeared; decreased E C D expression was closely associated with invasive growth and differentiation of gastric cancer. (P < 0 01), but not with invasive depth of gastric cancer, lymph node metastasis, vein, lymphatic infiltration (P> 005). Conclusion: The expression of ECD may determine the growth pattern and differentiation of gastric cancer, but has nothing to do with the invasion and metastasis potential of gastric cancer.
