大多数状细胞癌 (VSCC) 都表达Nectin4,这是抗体与药物联合体 (ADC) 的标. 这表明Enfortumab- Vedotin (EV) 可能是对VSCC的潜在治疗方法,需要进一步进行临床试验.
科学领域:
- 癌症学
- 翻译研究
- 分子病理学
背景情况:
- 在治疗固体瘤方面,抗体药物联合体 (ADC) 是有前途的.
- 恩福图马布-维多丁 (EV) 是一种已批准的针对尿道癌的Nectin4的ADC.
- 对于ADC的有效性来说,nectin4的表达非常重要.
研究的目的:
- 评估阴道状细胞癌 (VSCC) 中的Nectin4表达.
- 将Nectin4表达与VSCC分子亚型相关联.
- 评估Nectin4向ADC在VSCC治疗中的潜力.
主要方法:
- 使用免疫组织化学 (IHC) 来评估Nectin4的表达.
- 在55个VSCC活检中进行了半定量评分 (IRS).
- 在Nectin4 IRS和VSCC分子亚型 (HPV相关,HPV独立) 之间的相关性分析.
主要成果:
- 所有VSCC病例都表现出Nectin4的表达 (IRS中位数为6.0).
- 在85. 7%的HPV相关瘤和62. 9%的HPV独立瘤中观察到高Nectin4表达 (IRS> 4).
- 不同分子亚型的nectin4表达均高,包括预后不利的亚型.
结论:
- 大多数VSCC表现出高Nectin4表达.
- 像Enfortumab-Vedotin (EV) 这样的Nectin4向的ADC代表了VSCC的潜在治疗策略.
- 通过IHC进行Nectin4评估是可行的,支持对VSCC进行临床试验的需要.
