We here evaluated a next-generation mass spectrometer and found that it not suitable for a comprehensive protein analysis of blood. Therefore, we performed a microRNA analysis of blood. To exclude individual differences between patients, we focused on esophageal mucosal cancer patients who were scheduled to undergo endoscopic mucosal resection (EMR) in the present study. Forty-three patients were recruited from 3 institutes. We analyzed the expression of miRNAs in pre-treatment as well as post-treatment blood samples that were collected from 31 patients. Significant differences were observed in the expression of 11 miRNAs between pre-treatment and post-treatment samples. We will analyze these miRNAs in 30 patients with advanced esophageal cancer in a future study and evaluate their efficacy as biomarkers of esophageal cancer.

我们在这里评估了下一代质谱仪，发现它不适合对血液进行全面的蛋白质分析。因此，我们对血液进行了 microRNA 分析。为了排除患者之间的个体差异，我们在本研究中重点关注计划接受内镜粘膜切除术（EMR）的食管粘膜癌患者。从 3 个研究所招募了 43 名患者。我们分析了从 31 名患者收集的治疗前和治疗后血液样本中 miRNA 的表达。处理前和处理后样本中 11 种 miRNA 的表达存在显着差异。我们将在未来的研究中分析 30 名晚期食管癌患者的这些 miRNA，并评估它们作为食管癌生物标志物的功效。
