Esophageal cancer (ECa) is the 7th most incident cancer and the 6th leading cause of cancer-related death. Most patients are diagnosed with locally advanced or metastatic disease, enduring poor survival. Biomarkers enabling early cancer detection may improve patient management, treatment effectiveness, and survival, are urgently needed. In this context, epigenetic-based biomarkers such as DNA methylation are potential candidates. Herein, we sought to identify and validate DNA methylation-based biomarkers for early detection and prediction of response to therapy in ECa patients. Promoter methylation levels were assessed in a series of treatment-naïve ECa, post-neoadjuvant treatment ECa, and normal esophagus tissues, using quantitative methylation-specific PCR for COL14A1, GPX3, and ZNF569. ZNF569 methylation (ZNF569me) levels significantly differed between ECa and normal samples (p < 0.001). Moreover, COL14A1 methylation (COL14A1me) and GPX3 methylation (GPX3me) levels discriminated adenocarcinomas and squamous cell carcinomas, respectively, from normal samples (p = 0.002 and p = 0.009, respectively). COL14A1me & ZNF569me accurately identified adenocarcinomas (82.29%) whereas GPX3me & ZNF569me identified squamous cell carcinomas with 81.73% accuracy. Furthermore, ZNF569me and GPX3me levels significantly differed between normal and pre-treated ECa. The biomarker potential of a specific panel of methylated genes for ECa was confirmed. These might prove useful for early detection and might allow for the identification of minimal residual disease after adjuvant therapy.

基于DNA甲基化的食道癌检测

食道癌(ECa)是第七大最常见的癌症,也是与癌症相关死亡的第六大主要原因。大多数患者被诊断出患有局部晚期或转移性疾病,生存期较差。迫切需要能够早期发现癌症的生物标记物,以改善患者管理,治疗效果和生存率。在这种情况下,基于表观遗传学的生物标记物(例如DNA甲基化)是潜在的候选者。在本文中,我们寻求鉴定和验证基于DNA甲基化的生物标记物,以便早期检测和预测ECa患者对治疗的反应。使用针对COL14A1,GPX3和ZNF569的甲基化特异性PCR,评估了一系列初次治疗的ECa,新辅助治疗后的ECa和正常食道组织中的启动子甲基化水平。ECa和正常样品之间的ZNF569甲基化(ZNF569me)水平存在显着差异(p <0.001)。此外,COL14A1甲基化(COL14A1me)和GPX3甲基化(GPX3me)的水平分别区分了正常样品中的腺癌和鳞状细胞癌(分别为p = 0.002和p​​ = 0.009)。COL14A1me和ZNF569me准确地鉴定出了腺癌(82.29%),而GPX3me和ZNF569me鉴定出了鳞状细胞癌,其准确度为81.73%。此外,正常和预处理ECa之间的ZNF569me和GPX3me水平显着不同。确认了一组特定的甲基化基因对ECa的生物标志物潜力。这些可能被证明对早期发现很有用,并可能有助于确定辅助治疗后的最小残留疾病。COL14A1甲基化(COL14A1me)和GPX3甲基化(GPX3me)的水平分别区分了正常样品中的腺癌和鳞状细胞癌(分别为p = 0.002和p​​ = 0.009)。COL14A1me和ZNF569me准确地鉴定出了腺癌(82.29%),而GPX3me和ZNF569me鉴定出了鳞状细胞癌,其准确度为81.73%。此外,正常和预处理ECa之间的ZNF569me和GPX3me水平显着不同。确认了一组特定的甲基化基因对ECa的生物标志物潜力。这些可能被证明对早期发现很有用,并可能有助于确定辅助治疗后的最小残留疾病。COL14A1甲基化(COL14A1me)和GPX3甲基化(GPX3me)的水平分别区分了正常样品中的腺癌和鳞状细胞癌(分别为p = 0.002和p​​ = 0.009)。COL14A1me和ZNF569me准确地鉴定出了腺癌(82.29%),而GPX3me和ZNF569me鉴定出了鳞状细胞癌,其准确度为81.73%。此外,正常和预处理ECa之间的ZNF569me和GPX3me水平显着不同。确认了一组特定的甲基化基因对ECa的生物标志物潜力。这些可能被证明对早期发现很有用,并可能有助于确定辅助治疗后的最小残留疾病。002和p​​ = 0.009)。COL14A1me和ZNF569me准确地鉴定出了腺癌(82.29%),而GPX3me和ZNF569me鉴定出了鳞状细胞癌,其准确度为81.73%。此外,正常和预处理ECa之间的ZNF569me和GPX3me水平显着不同。确认了一组特定的甲基化基因对ECa的生物标志物潜力。这些可能被证明对早期发现很有用,并可能有助于确定辅助治疗后的最小残留疾病。002和p​​ = 0.009)。COL14A1me和ZNF569me准确地鉴定出了腺癌(82.29%),而GPX3me和ZNF569me鉴定出了鳞状细胞癌,其准确度为81.73%。此外,正常和预处理ECa之间的ZNF569me和GPX3me水平显着不同。确认了一组特定的甲基化基因对ECa的生物标志物潜力。这些可能被证明对早期发现很有用,并可能有助于确定辅助治疗后的最小残留疾病。确认了一组特定的甲基化基因对ECa的生物标志物潜力。这些可能被证明对早期发现很有用,并可能有助于确定辅助治疗后的最小残留疾病。确认了一组特定的甲基化基因对ECa的生物标志物潜力。这些可能被证明对早期发现很有用,并可能有助于确定辅助治疗后的最小残留疾病。
