摘  要:目的:观察生存素(Survivin)、淋巴管内皮细胞透明质酸受体-1(LYVE-1)在胃癌组织中的表达情况,探讨Survivin、LYVE-1在胃癌组织中表达意义及其相关性。方法采用免疫组织化学染色方法检测70例胃癌组织及50例胃溃疡组织中Survivin、LYVE-1的表达,分析其在胃癌组织中的表达与临床病理参数间的关系。结果胃癌组织中Survivin的阳性率为65.71%(46/70),胃溃疡组织中6.00%(3/50),差异有统计学意义(χ2=43.048, P <0.01)。胃癌中Survivin的阳性率:低分化为76.92%,T3-T4为75.00%,淋巴结阳性转移为75.61%,Ⅲ-Ⅳ期为77.08%,明显高于高、中分化(51.61%)、T1-T2(38.89%)、淋巴结阴性(51.72%)、Ⅰ-Ⅱ期(40.91%),差异有统计学意义( P <0.05);与患者年龄、性别、胃癌部位无关( P >0.05)。胃癌组织中 LYVE-1的阳性率为32.86%(23/70),胃溃疡组织中4.00%(2/50),差异有统计学意义(χ2=14.726, P <0.01)。胃癌中LYVE-1的阳性率:T3-T4为40.38%,淋巴结阳性转移为46.34%,Ⅲ-Ⅳ期为41.67%,明显高于T1-T2(11.11%)、淋巴结阴性(13.79%),Ⅰ-Ⅱ期(13.64%),差异有统计学意义( P <0.05);与患者年龄、性别、胃癌部位、细胞分化程度无关( P >0.05)。在胃癌中,LYVE-1表达与Survivin表达呈明显正相关( r =0.271, P <0.05)。结论在胃癌中,Survivin、LYVE-1均异常表达,参与胃癌的发生、发展,两者之间密切相关。Objective To investigate the expressions and clinical significance of survivin, and lymphatic vessel endothelial hyaluronan receptor 1 ( LYVE-1) in gastric cancers.Methods The expres-sions of survivin and LYVE-1 were detected with streptavidin avidin-peroxidase ( SP) immunohistochemical method in 70 cases of gastric cancers and 50 cases of normal gastric tissues.The relationship between the expressions of survivin and LYVE-1 with the clinicopathological parameters was analyzed.Results The ex-pression rate of survivin was 65.71%(46/70) in gastric cancers, and 6.00% (3/50) in normal gastric tissues, with statistically significant difference between two groups (χ2 =43.048, P 〈0.01) .The expres-sion of survivin was different in gastric cancers:survivin expression rate was 76.92%in poorly differentia-ted gastric carcinomas, 75.00%in T3 -T4 gastric carcinomas, 75.61%in the positive lymph node metas-tasis of gastric cancers, and 77.08%in the Ⅲ-Ⅳ gastric cancer tissues; which was significantly higher than the highly differentiated (51.61%), T1 -T2(38.89%), lymph node-negative (51.72%), andⅠ-Ⅱperiod (40.91%) ( P 〈0.05).The expression of survivin in gastric cancers was no obvious correlation with the age, gender and tumor site ( P 〉0.05).The expression rate of LYVE-1 was 32.86%(23/70) in gastric cancers, and 4.00%(2/50) in gastric ulcers, with significant difference between two groups (χ2 =14.726, P 〈0.01) .The expression of LYVE-1 was different in gastric cancers:LYVE-1 expression rate was 40.38%in T3 -T4 gastric carcinomas, 46.34%in the positive lymph node metastasis of gastric canc-ers, 41.67% in the Ⅲ -Ⅳ gastric cancer tissues; which was significantly higher than the T1 -T2 (11.11%), lymph node-negative (13.79%), andⅠ-Ⅱperiod (13.64%) ( P 〈0.05).The expres-sion of LYVE-1 in gastric cancers was no obvious correlation with the age, gender, tumor site, and the de-gree of differentiation ( P 〉0.05 ) .The
