survivin和CD44v6在非小细胞肺癌中的表达及意义

目的 探讨非小细胞肺癌(NSCLC)中survivin及CD44v6的表达及意义,以及二者的相关性.方法 采用SP免疫组化方法检测survivin及CD44v6在53例NSCLC组织、13例癌旁正常肺组织中的表达.结果 53例NSCLC癌组织中survivin、CD44v6阳性表达率分别是60.38%和69.81%,高于癌旁正常肺组织的表达(P<0.01).二者与淋巴结转移相关(P<0.05),与年龄、性别均无关(P>0.05).survivin的表达与临床TNM分期及肿瘤分化程度相关(P<0.05);与组织学类型无关(P>0.05).CD44v6在鳞癌的表达率远高于腺癌(P<0.05),与临床TNM分期及肿瘤分化程度无关(P>0.05).survivin与CD44v6之间无相关性(r=-0.058,P>0.05).结论 survivin有望作为评估NSCLC病变进展的指标,CD44v6可用来鉴别诊断NSCLC中的鳞癌,二者有可能成为预测NSCLC转移的指标.survivin、CD44v6可能是NSCLC发生发展过程中的两个独立事件.

Expression and significance of survivin and CD44v6 protein in non-small cell lung cancer

Objective To investigate the expression and significance of survivin and CD44v6 in non-small cell lung cancer (NSCLC) and their correlation. Methods SP immunohistochemical technique was used to detect the expression of survivin and CD44V6 protein in 53 cases of NSCLC and 13 cases of para-eaneer nor-mal tissues. Results The positive rate of survivin and CD44v6 in NSCLC was 60. 38% and 69. 81% respec-tively,which was higher than that of normal pulmonary tissues adjacent to carcinoma(P <0. 01). The expres-sion of survivin and CD44v6 in NSCLC was related to lymph node metastasis (P < 0. 05), but not to patients' age and gender(P>0.05). The expression of survivin was related to TNM stages and cell differentiation (P <0. 05) ,but not to histology type(P >0. 05). The expression of CD44v6 in squamous carcinoma was significantly higher than that of adenocareinoma (P <0. 05),but the expression of CD44v6 was not related to TNM stages and cell differentiation (P >0. 05). There was no correlation between the expression of survivin and C1)44v6 (r = -0. 058, P >0. 05). Conclusion Survivin might be used to evaluate NSCLC development;CD44v6 might be used for the differential diagnosis of squamous carcinoma in NSCLC;both of them might be helpful to predict the metastasis of NSCLC. They might be two independent events in the process of NSCLC genesis and develop-ment.
