【摘要】: 目的 探討鼻咽癌患者原發(fā)灶和復(fù)發(fā)灶中Cox-2、bcl-2、EGFR、Ki-67、cyclin D1、survivin表達(dá)差異比較,為篩選監(jiān)測(cè)鼻咽癌復(fù)發(fā)的特異性分子標(biāo)志物提供理論依據(jù)。 方法 選取1999年7月至2008年7月在我院確診為鼻咽癌的存檔蠟塊40例,原發(fā)蠟塊(原發(fā)組)和復(fù)發(fā)蠟塊(復(fù)發(fā)組)各占20例,其中屬同一患者原發(fā)灶與復(fù)發(fā)灶自身前后對(duì)照者4例。標(biāo)本采用免疫組化EnVsion法檢測(cè)腫瘤組織中Cox-2、bcl-2、EGFR、Ki-67、cyclin D1、survivin的表達(dá)情況,并對(duì)實(shí)驗(yàn)結(jié)果進(jìn)行x2檢驗(yàn)。結(jié)果(1)原發(fā)組Cox-2、bcl-2、EGFR、Ki-67、cyclin D1、survivin的陽(yáng)性表達(dá)率分別為85%(17/20)、100%(20/20)、95%(19/20)、55%(11/20)、25%(5/20)及30%(6/20),其中bcl-2的強(qiáng)陽(yáng)性表達(dá)率為40%(8/20)。 (2)復(fù)發(fā)組Cox-2、bcl-2、EGFR、Ki-67、cyclin D1、survivin的陽(yáng)性表達(dá)率分別為60%(12/20)、65%(13/20)、85%(17/20)、40%(8/20)、25%(5/20)及20%(4/20),其中bcl-2的強(qiáng)陽(yáng)性表達(dá)率為40%(8/20)。 (3)復(fù)發(fā)組中Cox-2、bcl-2、EGFR、Ki-67、cyclin D1、survivin的陽(yáng)性表達(dá)率均較原發(fā)組有不同程度的下降,這種差異除bcl-2 (P0.01)外均無(wú)統(tǒng)計(jì)學(xué)意義。 結(jié)論 (1)鼻咽癌患者原發(fā)灶和復(fù)發(fā)灶中Cox-2、bcl-2、EGFR、Ki-67、cyclin D1、survivin均呈高表達(dá)。 (2)鼻咽癌原發(fā)灶和復(fù)發(fā)灶中各標(biāo)志物的表達(dá)無(wú)明顯差異,但bcl-2在復(fù)發(fā)灶中表達(dá)明顯下調(diào)。
[Abstract]:Objective to investigate the difference of expression of Cox-2,bcl-2,EGFR,Ki-67,cyclin D 1 gene survivin in primary and recurrent nasopharyngeal carcinoma (NPC) patients, and to provide theoretical basis for screening specific molecular markers for the detection of NPC recurrence. Methods from July 1999 to July 2008, 40 cases of nasopharyngeal carcinoma (NPC) were diagnosed in our hospital, 20 cases were primary wax block (primary group) and 20 cases were recurrent wax block (recurrent group). Among them, 4 cases belonged to the same patient with primary and recurrent foci before and after control. Immunohistochemical EnVsion method was used to detect the expression of Cox-2,bcl-2,EGFR,Ki-67,cyclin D 1 Cox-2,bcl-2,EGFR,Ki-67,cyclin in tumor tissues and x2 test was used to test the results. 緇撴灉(1)鍘熷彂緇凜ox-2,bcl-2,EGFR,Ki-67,cyclin D1,survivin鐨勯槼鎬ц〃杈劇巼鍒嗗埆涓,
