Clin Chem:血液中游离SHOX2 DNA甲基化作为肾细胞癌风险分层的分子分期参数

2019-07-20 gladiator MedSci原创

现如今,新的靶向治疗和免疫疗法已经极大地改善了晚期和转移性肾细胞癌<span lang="EN-US" style="font-size:12.0pt;mso-bidi-font-size:14.0pt;font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;; mso-fareast-font-family:宋体;mso-bidi-font-

现如今,新的靶向治疗和免疫疗法已经极大地改善了晚期和转移性肾细胞癌(RCCs)的治疗方案。然而,当前仍迫切需要准确的诊断检测来识别高危患者。在此,本项前瞻性观察队列研究定量分析了循环游离DNA (ccfDNA)RCC组织中SHOX2 mRNA的表达,以及SHOX2基因体甲基化的风险分层情况。

RCC组织样本(n = 760)的训练和测试队列中,研究人员分别回顾性和前瞻性地检测SHOX2甲基化的临床表现。训练队列纳入SHOX2 mRNA表达分析。此外,在检测队列中匹配的血浆样本(n = 100)中,前瞻性地检测了治疗前SHOX2 ccfDNA甲基化,并评估对疾病分期的能力,以及对高危死亡患者的识别能力。

研究结果显示,在RCC组织中,SHOX2基因甲基化与mRNA表达呈正相关关系,(训练队列:斯皮尔曼ρ= 0.23,P < 0.001)SHOX2甲基化在组织和血浆与疾病进程(训练队列:ρ= 0.28,P < 0.001;测试组/组织:ρ= 0.40,P < 0.001;测试组/等离子体:ρ= 0.34,P = 0.001),以及初始部分或根除性肾脏切除手术后死亡的风险显著相关(训练队列:风险比(人力资源)= 1.40 (95% CI, 1.24 - -1.57), P < 0.001;检测队列/组织:HR = 1.16 (95% CI, 1.07-1.27) P = 0.001;检测队列/血浆:HR = 1.50 (95% CI, 1.29-1.74) P < 0.001

研究表明,治疗前SHOX2 ccfDNA甲基化检测可鉴别肾细胞癌患者肾切除后的高死亡风险。这些患者可能受益于辅助治疗或早期开始姑息治疗。
