Colorectal cancer (CRC) is the second-most commonly diagnosed cancer worldwide. Early diagnosis improves prognosis and long-term outcomes. Several studies have found tumor-associated autoantibodies in CRC patients. We aimed to provide an overview on CRC-associated autoantibodies and their reported diagnostic, prognostic, and predictive performance when used singly or in combination. We systematically reviewed studies on CRC-related autoantibodies published till March 2018 and critically analyzed the role of these autoantibodies in CRC. In general, autoantibodies were of low sensitivity when tested individually and the diagnostic characteristics improved when tested in combination. Autoantibodies against CCD83, carcinoembryonic antigen, MAPKAPK3, RPH 3AL, SEC61b, and SPAG9 showed high sensitivity and specificity when tested alone. When tested in combination, autoantibodies against three antigens (PIM1, MAPKAPK3, and ACVR2B) showed high sensitivity and specificity. So far, most CRC-associated autoantibodies have been evaluated in single or in a small number of studies. In contrast, anti-p53 antibodies have been studied in a larger number of CRC studies, but, so far, none of them have high diagnostic characteristics. CRC-associated autoantibodies are detectable from the early stages of malignancy, pointing to their possible use in the early detection of CRC. Some studies suggest that CRC-associated autoantibodies may be a guide to prognosis in CRC.

自身抗体在结直肠癌的诊断、预后和预测中的作用


结直肠癌 (CRC) 是全球第二大最常见的癌症。早期诊断可改善预后和长期结果。几项研究在 CRC 患者中发现了肿瘤相关的自身抗体。我们旨在概述 CRC 相关的自身抗体及其报告的单独或联合使用时的诊断、预后和预测性能。我们系统回顾了截至 2018 年 3 月发表的关于 CRC 相关自身抗体的研究,并批判性地分析了这些自身抗体在 CRC 中的作用。一般来说,自身抗体在单独测试时敏感性较低,而在联合测试时诊断特征得到改善。针对 CCD83、癌胚抗原、MAPKAPK3、RPH 3AL、SEC61b 和 SPAG9 的自身抗体在单独测试时显示出高灵敏度和特异性。当联合测试时,针对三种抗原(PIM1、MAPKAPK3 和 ACVR2B)的自身抗体显示出高灵敏度和特异性。到目前为止,大多数 CRC 相关的自身抗体已在单一或少数研究中进行了评估。相比之下,抗 p53 抗体已在大量 CRC 研究中进行了研究,但到目前为止,它们都没有高诊断特征。CRC 相关的自身抗体可在恶性肿瘤的早期阶段检测到,这表明它们可能用于早期检测 CRC。一些研究表明,CRC 相关的自身抗体可能是 CRC 预后的指南。相比之下,抗 p53 抗体已在大量 CRC 研究中进行了研究,但到目前为止,它们都没有高诊断特征。CRC 相关的自身抗体可在恶性肿瘤的早期阶段检测到,这表明它们可能用于早期检测 CRC。一些研究表明,CRC 相关的自身抗体可能是 CRC 预后的指南。相比之下,抗 p53 抗体已在大量 CRC 研究中进行了研究,但到目前为止,它们都没有高诊断特征。CRC 相关的自身抗体可在恶性肿瘤的早期阶段检测到,这表明它们可能用于早期检测 CRC。一些研究表明,CRC 相关的自身抗体可能是 CRC 预后的指南。
