简介：摘要目的C－erbB－２、Pgp蛋白表达与CRC临床病理特征的关系.方法免疫组化检测蛋白表达,SPSS软件分析数据.结果C－erbB－２蛋白表达与临床病理特征均无统计学相关性(P＞０．０５).Pgp蛋白表达在大体溃疡型(８６．８８％)与隆起型(７５．５１％)间统计学差异显著(P＜０．０５);在肿瘤侵润深度(肠壁浆膜层或累及临近器官９０．４８％、肠壁全层８８．４２％、肌层７２．２２％、粘膜下层６０％)间统计学差异显著(P＜０．０５);在淋巴结有无转移(９３．９８％,７５．９１％)间统计学差异特别显著(P＜０．０１).C－erbB－２与Pgp蛋白表达间无统计学相关性(P＞０．０５).结论多数CRC可能有原发性多药耐药;Pgp蛋白可作反映CRC生物学行为的标志物,恶性程度较高的CRC可能易出现原发性多药耐药.关键词C－erbB－２Pgp结直肠癌多药耐药TheClinicalSignificanceofC－erbB－２andPgpProteinExpressionsinColorectalCarcinomaAbstractObjectiveExplorethefeasibilitythatC－erbB－２andPgpproteinexpressionsareusedtoassessbiologicalbehaviorsandprognosisofcolorectalcancer．MethＧodsImmunohistochemistrywasusedtodetecttheproteinexpressions．SPSSstatisticsoftwarewasusedtoanalyzetherelationshipoftheproteinexpressionstoclinicalpathoＧlogicalfeaturesofthecancerandthecorrelationbetweentheproteinexpressions．ResultsTheexpressionofC－erbB－２proteinhadnosignificantrelationstocharacteristicsofthecancers(P＞０．０５)．ThepositiveratesofPgpproteinexpressioningrossshapeofulcerandprotrusionwere８６．８８％and７５．５１％andtherewasstatisticalsignificancebetweenthem(P＜０．０５)．Thepositiveratesininvasionstoadjacentorgansorpenetrationserosa,toserosaoradventitia,tomuscleandtosubmucosawere９０．４８％,８８．４２％,７２．２２％and６０％respectivelyandtherewerestatisticalsignificancesamongthem(P＜０．０５)．Thepositiveratesintumorwithandwithoutlymphnodemetastasiswere９３．９８％and７５．９１％andtherewasstatisticalsignificancebetweenthem(P＜０．０１)．TherewerenostatisticalcorrelationsbetweenexpressionsofC－erbB－２andPgpproteinincolorectalcancer(P＞０．０５)．ConclusionsThemajorcolorectalcancersmighthaveaprimarymultidrugresistance．PgpproteincanbeseenasapotentialmarkerforjudgeＧmentmKaelyignWaonrtdsbehaviorofcolorectalcancerandthecolorectalcancerwithhighmalignancymighthavebigchancetobeprimarymultidrugresistance．C－erbB－２PgpCRCmultidrugresistance中图分类号R７３５．３文献标识码B文章编号１００８－６３１５(２０１５)１２－０３７５－０２
