摘要 目的研究凋亡抑制基因Survivin在鼻咽癌中的表达以及Survivin的表达与鼻咽癌淋巴转移、临床分期之间的相关性。方法应用免疫组化技术分析68例鼻咽癌组织和45例鼻咽慢性炎症组织中Survivin的表达。结果68例鼻咽癌组织中,Survivin表达阳性率为69·1%(47/68),45例鼻咽慢性炎症组织中,Survivin表达阳性率为15·6%(7/45),两者比较差异有统计学意义(P<0·01)。有淋巴转移的鼻咽癌组织,Survivin表达为71·7%(33/46),无淋巴转移的鼻咽癌组织Survivin表达为63·6%(14/22),两者比较差异无统计学意义(P>0·05)。早期(临床Ⅰ、Ⅱ期)鼻咽癌组织,Survivin表达为70·6%(12/17),晚期(临床Ⅲ、Ⅳ期)鼻咽癌组织,Survivin表达为68·6%(35/51),两者比较差异无统计学意义(P>0·05)。结论Survivin的表达改变发生在鼻咽癌的早期,它的表达水平升高可能在鼻咽组织癌变早期起重要作用;Survivin的表达与鼻咽癌的转移、临床分期可能无相关。 Objective To study expression of survivin, a suppressor of cell apoptosis, in nasopharyngeal carcinoma(NPC) and reveal the corrdation between expression of survivin and clinical stages, lymph node metastasis of NPC.Methods Immunohistrochemical stain was used to evaluate the expression of survivin in 68 cases of NPC and 45 cases of nasopharyngeal chronic inflammation tissues. Results The positive rate of survivin was 69.1% (47/68) in 68 eases of NPC, and 15.6 % (7/45) in 45 eases of nasopharyngeal chronic inflammation tissues, the difference was significant(P〈0.01). The positive rate of survivin was 71.7% (33/46) in NH2 with lymph node metastasis and 63.6 % (14/22) in NPC without lymph node metastasis; the positive rate of survivin was 70.6 % (12/17) in earlier NPC (clinical stage Ⅰ and Ⅱ ), 68.6 % (35/51) (12/17) in later NPC ( clinical stage Ⅲ and Ⅳ ), the expression of survivin had no significant eorrelation with lymph node metastasis or clinical stages of NPC (P〉0.05%) .Conclusion Expression of survivin has already changed in earlier stage of NPC, this alteration may play a key role in carcinogenesis of nasopharyngeal epithelium. Survivin may not be involved in clinical stages and lymph node metastasis of NPC.
