文檔簡介
1、目的:研究治療前血清學(xué)腫瘤標(biāo)志物細(xì)胞角蛋白19片段抗原21-1(cytokeratin 19 ragment antigen21-1,CYFRA21-1)、癌胚抗原(carcinoembryonic antigen,CEA)、血紅蛋白(haematoglobin,HB)以及治療過程中HB水平能否預(yù)測同步放化療對食管鱗癌有效性。
材料方法:入組96例Ⅰ-IV期原發(fā)ESCC患者,治療前應(yīng)用酶聯(lián)免疫吸附法測定血清CYFRA21-
2、1、CEA及HB水平,治療過程中監(jiān)測A及HB水平。CYFRA21-1、CEA、A臨界值分別為3.4ng/mL、3.3ng/mL、3.5g/dl。HB分三個(gè)水平:<11.0g/dL,11.0-14.0g/dL,>14.0g/dL。分析治療前CYFRA21-1、CEA、HB及治療過程中HB表達(dá)水平與放化療敏感性的關(guān)系。
結(jié)果:以全緩解率和分緩解率為有效,增強(qiáng)CT評價(jià)ESCC原發(fā)灶有效率在CEA高表達(dá)組為57.14%(16/28
3、)而在低表達(dá)組為89.71%(62/67),差異顯著(P=0.000);CYFRA21-1高表達(dá)組為62.50%(20/32)而在低表達(dá)組為92.18%(59/64),具有顯著統(tǒng)計(jì)學(xué)差異(P=0.000)。治療前及治療過程中HB水平與放化療療效顯著相關(guān)(P=0.005,0.033)。如果將CYFRA21-1>3.4ng/mL、CEA>3.3 ng/mL、HB>14.0g/dL或<11.0g/dL視為放化療敏感性的危險(xiǎn)因素。分析結(jié)果顯示:
