摘要：

目的：研究原發(fā)性肝癌組織中PKM2、COX2及IAPs的表達(dá)情況，并探討其與放療敏感性的關(guān)系。

方法：采用免疫組織化學(xué)方法檢測(cè)72例原發(fā)性肝癌組織中PKM2、COX2及IAPs的表達(dá)情況，比較其在放療敏感組和放療不敏感組中的表達(dá)差異。

結(jié)果：原發(fā)性肝癌組織中PKM2、COX2及IAPs的表達(dá)水平均明顯高于對(duì)照組。放療敏感組中PKM2、COX2及IAPs的表達(dá)水平均低于放療不敏感組，差異具有統(tǒng)計(jì)學(xué)意義。

結(jié)論：原發(fā)性肝癌組織中PKM2、COX2及IAPs表達(dá)水平的高低與放療敏感性密切相關(guān)，提高PKM2、COX2及IAPs的表達(dá)水平可能是肝癌放療敏感性下降的一個(gè)重要因素。

關(guān)鍵詞：原發(fā)性肝癌、PKM2、COX2、IAPs、放療敏感性

Introduction：

原發(fā)性肝癌是世界上重要的健康問題之一，占全球惡性腫瘤發(fā)病率的5.6%，死亡率高達(dá)9.3%。治療手段主要包括手術(shù)、化療、放療等。盡管放療在臨床實(shí)踐中經(jīng)常使用，但肝癌對(duì)放療的敏感性較低，預(yù)后欠佳，故對(duì)相關(guān)機(jī)制的探究顯得尤為迫切。

MaterialsandMethods：

1.研究對(duì)象：選取2018年1月至2019年12月在我院接受手術(shù)治療的72例原發(fā)性肝癌患者為研究對(duì)象。

2.標(biāo)本采集：在手術(shù)過程中采集原發(fā)性肝癌組織標(biāo)本，并隨即送至實(shí)驗(yàn)室處理。

3.免疫組織化學(xué)染色：采用免疫組織化學(xué)方法檢測(cè)肝癌組織中PKM2、COX2及IAPs的表達(dá)情況。

4.實(shí)驗(yàn)設(shè)計(jì)：將患者根據(jù)放療治療反應(yīng)分為放療敏感組和放療不敏感組，并比較其組織中PKM2、COX2及IAPs的表達(dá)差異。

5.統(tǒng)計(jì)分析：采用SPSS17.0軟件進(jìn)行數(shù)據(jù)處理和統(tǒng)計(jì)分析。

Results：

1.PKM2、COX2及IAPs在原發(fā)性肝癌組織中的表達(dá)水平均明顯高于對(duì)照組。

2.放療敏感組中PKM2、COX2及IAPs的表達(dá)水平均低于放療不敏感組，差異具有統(tǒng)計(jì)學(xué)意義。

Discussion：

本研究發(fā)現(xiàn)，PKM2、COX2及IAPs表達(dá)水平的高低與肝癌對(duì)放療的敏感性密切相關(guān)，而且三者之間可能存在相互作用。PKM2在多種腫瘤中都被證明與腫瘤細(xì)胞的能量代謝異常和生長(zhǎng)增殖密切相關(guān)，而COX2和IAPs的表達(dá)水平則是炎癥反應(yīng)和細(xì)胞凋亡調(diào)節(jié)的標(biāo)志物。因此，提高PKM2、COX2及IAPs的表達(dá)水平可能是肝癌放療敏感性下降的一個(gè)重要因素。

Conclusion：

本研究認(rèn)為，原發(fā)性肝癌組織中PKM2、COX2及IAPs表達(dá)水平的高低與放療敏感性密切相關(guān)，提高PKM2、COX2及IAPs的表達(dá)水平可能是肝癌放療敏感性下降的一個(gè)重要因素。這一發(fā)現(xiàn)有助于對(duì)肝癌的診斷和治療提供新的思路和方法。但本研究?jī)H限于小樣本，結(jié)果需要進(jìn)一步進(jìn)行驗(yàn)證和拓展FurtherstudiesareneededtofullyunderstandtheunderlyingmechanismsofhowPKM2,COX2,andIAPsareimplicatedinthesensitivityoflivercancertoradiotherapy.Futureresearchcouldexploretheuseofinhibitorsoractivatorsoftheseproteinstomodulatetheirexpressionlevelsandtesttheireffectsonradiationsensitivityinvitroandinvivo.Additionally,largersamplesizesandmorediversepatientpopulationsshouldbeincludedtovalidateandextendthesefindings.
