摘要 目的探讨消化系统恶性肿瘤组织中生长抑素受体亚型SSTR2、SSTR5 mRNA表达状况及其与肿瘤的相关性。方法收集消化系肿瘤标本共66例,均经手术及病理证实。男性44例,女性22例,PCR扩增SSTR2、SSTR5 mRNA,并进行琼脂糖凝胶电泳,测其OD值并进行分析。结果不同肿瘤SSTR2 mRNA的表达频率不同,肝癌组织明显高于胃癌、结肠癌和胰腺癌(P<0.05),胃癌、结肠癌和胰腺癌之间表达无明显差异。肝癌癌组织与癌旁组织之间表达水平无明显差异,但与正常组织表达水平有显著差异(P<0.05);胃癌、结肠癌和胰腺癌癌组织与癌旁组织、正常组织之间表达无显著性差异(P>0.05)。SSTR5 mRNA的表达频率和表达水平在消化系肿瘤中差异不显著(P>0.05)。结论(1)胃癌、结肠癌、肝癌及胰腺癌组织中有SSTR2、5亚型表达,以SSTR2亚型为主。(2)SSTR2亚型在胃癌、结肠癌、肝癌及胰腺癌的表达频率及表达水平不同。在肝癌中呈高表达,在胃癌、结肠癌及胰腺癌中表达水平较低。(3)SSTR2、5亚型的表达频率、表达水平与癌组织分化程度、有无淋巴结转移密切相关,结肠癌与肿瘤分期有密切关系。(4)SSTR2亚型鉴定对胃癌、结肠癌、肝癌及胰腺癌是否适合生长抑素治疗具有一定指导意义。
