由于大多數(shù)患者是在晚期確診，卵巢癌仍然是最致命的婦科惡性腫瘤。沒有單一的生物標(biāo)志物具有所需的靈敏度和特異性。

耶魯大學(xué)醫(yī)學(xué)院婦產(chǎn)科，哈佛大學(xué)布列根和婦女醫(yī)院（Brigham and Women’s Hospital，BWH），丹娜法伯癌癥研究院，約翰霍普金斯大學(xué)醫(yī)學(xué)院西德尼Kimmel綜合癌癥中心等，聯(lián)合開發(fā)了一組新的生物標(biāo)志物，用于早期發(fā)現(xiàn)高級(jí)別漿液性卵巢癌。結(jié)果發(fā)表在最新一起婦產(chǎn)科腫瘤權(quán)威雜志：Gynecologic Oncology。 

臨床研究設(shè)計(jì)：

1. 候選因子：12個(gè)：IL-1Ra, IL-6, Dkk-1, uPA, E-CAD, ErbB2, SLPI, HE4, CA125, LCN2,MSLN, and OPN

2. 研究對(duì)象： 172病人（有婦科良性病變，或高級(jí)別漿液性卵巢腺癌等)

3. 技術(shù)平臺(tái)： Ella Simple Plex （ProteinSimple）

4. 結(jié)果：CA125, HE4, E-CAD, IL-6 四因子組成的panel具有特異性診斷漿液性卵巢癌的臨床價(jià)值。     

a)      卵巢癌病人versus無腫瘤對(duì)照組：特異性100%，陽(yáng)性預(yù)測(cè)價(jià)值100%，靈敏度 86.4%

b)      卵巢癌病人versus婦科良性疾病對(duì)照組：特異性100%，陽(yáng)性預(yù)測(cè)價(jià)值100%，靈敏度 87.2%

c)      卵巢癌病人versus無婦科良性疾病對(duì)照組：特異性100%，陽(yáng)性預(yù)測(cè)價(jià)值100%，靈敏度 98.4%

d)      早期漿液性卵巢癌 Versus無腫瘤對(duì)照組：特異性95.7%，陽(yáng)性預(yù)測(cè)價(jià)值88.9%，靈敏度 84.2%  

文中，作者特別注明選擇Ella simple plex進(jìn)行本項(xiàng)研究的原因：

Our study is one such effort to identify a panel of multiple serum biomarkers which is not just sensitive and specific, but also time-efficient and cost-effective. Simple Plex™is a new multi-analyte immunoassay platform, which has been proven to have significant advantages over traditional approaches in terms of low volume requirements (2.5 to 25 μL), sensitivity, and reproducibility [34,35]. Simple Plex™ eliminates inconsistency in sample handling and  produces results in a short amount of time, thus providing results with minimal error and in timely fashion. Simplex Plex™ costs much less and would be more cost-efficient to analyze multiple biomarkers.
