考虑到需要提高非侵入性方法检测结直肠肿瘤,特别是腺瘤的灵敏度,我们比较了粪便试验,该试验使用了针对结肠腺瘤成分的单克隆抗体(Mab),命名为Adnab-9(腺瘤抗体9),识别N-连接的87 kDa糖蛋白,与gFOBT,其显示可降低CRC死亡率。p87免疫组化检测对腺瘤(数量<3)、晚期腺瘤(OR 4.21[CI 2.47-7.15])或两者联合(OR 3.35[CI 2.47 - 4.53])的敏感性(OR 3.64[CI 2.37-5.58])显著高于gFOBT(基于愈创木脂的粪便潜血试验)。p87免疫组织化学显示区域潘氏细胞(PC)表达主要在右侧结肠中,并且在非裔美国人的盲肠中显著减少(p < 0.0001)。在一部分患者中,我们获得了其他体液,如尿液、结肠流出物和唾液。尿液检查(器官特异性新抗原)显示晚期腺瘤的显著差异(p < 0.047)。我们得出结论,粪便p87检测比gFOBT和Adnab-9更敏感,可用于更好地指导结肠镜筛查工作。
Given the need to improve the sensitivity of non-invasive methods to detect colorectal neoplasia, particularly adenomas, we compared a fecal test using a monoclonal antibody (Mab) raised against constituents of colonic adenomas designated Adnab-9 (Adenoma Antibody 9), recognizing an N-linked 87 kDa glycoprotein, to gFOBT, which is shown to reduce CRC mortality. p87 immunohistochemistry testing is significantly more sensitive (OR 3.64[CI 2.37–5.58]) than gFOBT (guaiac-based fecal occult blood test) for adenomas (<3 in number), advanced adenomas (OR 4.21[CI 2.47–7.15]), or a combination of the two (OR 3.35[CI 2.47–4.53]). p87 immunohistochemistry shows regional Paneth cell (PC) expression mainly in the right-sided colon and is significantly reduced in the ceca of African Americans (p < 0.0001). In a subset of patients, we obtained other body fluids such as urine, colonic effluent, and saliva. Urine tests (organ-specific neoantigen) showed a significant difference for advanced adenomas (p < 0.047). We conclude that fecal p87 testing is more sensitive than gFOBT and Adnab-9 and could be used to better direct the colonoscopy screening effort.
