几项研究报告了癌症中的自身抗体特征。这些研究中的大多数分析了成人肿瘤,并将肿瘤患者的血清反应性模式与健康对照的模式进行了比较。在这里,我们比较了神经母细胞瘤和肾母细胞瘤两种不同儿童肿瘤患者的自身免疫反应。我们能够区分未经治疗的神经母细胞瘤患者和未经治疗的肾母细胞瘤患者,准确性为86.8%,灵敏度为87.0%,特异性为86.7%。将经治疗的神经母细胞瘤患者与经治疗的肾母细胞瘤患者的分离产生了相当的结果,准确度为83.8%。我们还鉴定了对两种肿瘤类型之间的分化贡献最大的抗原。这些抗原的分析表明,神经母细胞瘤是相当多的免疫原性比肾母细胞瘤。尚未发现报告的抗原与其他肿瘤和对照之间的比较分析相关。总之,神经母细胞瘤似乎是一种高度免疫原性的肿瘤,正如将该肿瘤与Wilms瘤区分开来的大量抗原所证明的那样。
Several studies report autoantibody signatures in cancer. The majority of these studies analyzed adult tumors and compared the seroreactivity pattern of tumor patients with the pattern in healthy controls. Here, we compared the autoimmune response in patients with neuroblastoma and patients with Wilms tumor representing two different childhood tumors. We were able to differentiate untreated neuroblastoma patients from untreated Wilms tumor patients with an accuracy of 86.8%, a sensitivity of 87.0% and a specificity of 86.7%. The separation of treated neuroblastoma patients from treated Wilms tumor patients' yielded comparable results with an accuracy of 83.8%. We furthermore identified the antigens that contribute most to the differentiation between both tumor types. The analysis of these antigens revealed that neuroblastoma was considerably more immunogenic than Wilms tumor. The reported antigens have not been found to be relevant for comparative analyses between other tumors and controls. In summary, neuroblastoma appears as a highly immunogenic tumor as demonstrated by the extended number of antigens that separate this tumor from Wilms tumor.
