摘    要:目的探讨前列腺癌及癌前病变组织中GDFl5基因的表达情况及临床意义。方法运用组织芯片技术及免疫组化SP法检测72例前列腺癌组织(PCa组,其中Gleason评分5~7分42例,〉7分30例)、22例高级别前列腺上皮内瘤组织(PIN组)、23例良性前列腺增生组织(BPH组)中GDFl5蛋白的表达和分布情况。结果GDFl5在PCa、PIN、BPH组中的阳性表达率分别为95.8%、727%、87%;其在PCa及PIN组织中的阳性表达率均明显高于BPH组织(均P〈0.05),而且在PCa组织中的阳性表达率也明显高于PIN组织(P〈0.05)。中分化PCa组织中GDFl5阳性表达率为92.9%(39/42),低分化PCa组织中为100.0%(30/30),差异无统计学意义(P〉0.05)。结论GDFl5在前列腺癌中高表达,对前列腺癌的发生、发展可能起到重要作用。检测GDFl5在正常前列腺组织、高级别PIN、前列腺癌组织中的表达情况。有助于病理学上早期诊断前列腺癌。

Abstract:Objective To investigate the expression and clinic significance of GDF15 protein in prostatic intraepithelial neoplasia and adenocarcinoma. Methods GDF15 protein expression was evaluated in 73 cases of prostate carcinoma, 22 high grade prostatic intraepithelial neoplasia (PIN) and 23 benign prostatic hyperplasis (BPH) by immunohistochemistry SP and tissue microarray. Results The positive rates of GDF15 protein were 95.8% (69/72), 72.7% (16/22) and 8.7% (2/23) in prostate carcinoma, high grade PIN and BPH, respectively (P〈0.05). There was a significant difference in GDF15 expression between high grade PIN and BPH (P〈0.05), but no significant difference between moderate differentiated prostatic cancer (the Gleason histological score:5-7) and the lower one (the Gleason histological score: 8-10)(P〉0.05 ). Conclusion GDE15 may be involved in the development of prostatic carcinoma and might be used for early diagnosis of prostatic carcinoma.
Keywords:Prostatic carcinoma  GDF15  Tissue microarray  Immunohistochemistry
