【摘要】: 目的 探讨鼻咽癌患者原发灶和复发灶中Cox-2、bcl-2、EGFR、Ki-67、cyclin D1、survivin表达差异比较,为筛选监测鼻咽癌复发的特异性分子标志物提供理论依据。 方法 选取1999年7月至2008年7月在我院确诊为鼻咽癌的存档蜡块40例,原发蜡块(原发组)和复发蜡块(复发组)各占20例,其中属同一患者原发灶与复发灶自身前后对照者4例。标本采用免疫组化EnVsion法检测肿瘤组织中Cox-2、bcl-2、EGFR、Ki-67、cyclin D1、survivin的表达情况,并对实验结果进行x2检验。结果(1)原发组Cox-2、bcl-2、EGFR、Ki-67、cyclin D1、survivin的阳性表达率分别为85%(17/20)、100%(20/20)、95%(19/20)、55%(11/20)、25%(5/20)及30%(6/20),其中bcl-2的强阳性表达率为40%(8/20)。 (2)复发组Cox-2、bcl-2、EGFR、Ki-67、cyclin D1、survivin的阳性表达率分别为60%(12/20)、65%(13/20)、85%(17/20)、40%(8/20)、25%(5/20)及20%(4/20),其中bcl-2的强阳性表达率为40%(8/20)。 (3)复发组中Cox-2、bcl-2、EGFR、Ki-67、cyclin D1、survivin的阳性表达率均较原发组有不同程度的下降,这种差异除bcl-2 (P0.01)外均无统计学意义。 结论 (1)鼻咽癌患者原发灶和复发灶中Cox-2、bcl-2、EGFR、Ki-67、cyclin D1、survivin均呈高表达。 (2)鼻咽癌原发灶和复发灶中各标志物的表达无明显差异,但bcl-2在复发灶中表达明显下调。
[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. 缁撴灉(1)鍘熷彂缁凜ox-2,bcl-2,EGFR,Ki-67,cyclin D1,survivin鐨勯槼鎬ц〃杈剧巼鍒嗗埆涓,
