摘要 目的研究肿瘤坏死因子α(TNF-α)和表皮生长因子受体(EGFR)在胃癌中表达的相关性及其与临床、病理和预后之间的关系。方法应用免疫组织化学方法检测68例胃癌、癌旁组织及30例正常胃黏膜组织中TNF-α和EGFR的表达情况。结果TNF-α和EGFR在68例胃癌组织中的阳性表达率分别为54.4%(37/68)和51.5%(35/68),在癌旁组织中的阳性表达率分别为33.8%(23/68)和14.7%(10/68),在30例正常胃黏膜组织表达率分别为16.7%(5/30)和6.67%(2/30),三组TNF-α、EGFR表达差异显著(P<0.05)。EGFR的表达与胃癌的分化程度无关,与淋巴结转移、浸润程度显著相关(P<0.01);TNF-α的表达与胃癌的分化程度、淋巴结转移相关(P<0.05),但与浸润深度无显著相关。胃癌组织中TNF-α和EGFR表达之间呈正相关。结论TNF-α、EGFR的联合检测对判断胃癌恶性程度有重要价值,其阳性表达与胃癌的预后相关。
