Gastric Cancer:L1甲基化与肿瘤浸润淋巴细胞的组合可作为晚期胃癌的预后指标

2020-05-09 MedSci原创 MedSci原创

已知高密度的肿瘤浸润淋巴细胞(TIL)与延长的生存时间有关,而肿瘤L1亚甲基化与胃癌(GC)患者的缩短的生存时间有关。

背景: 已知高密度的肿瘤浸润淋巴细胞(TIL)与延长的生存时间有关,而肿瘤L1亚甲基化与胃癌(GC)患者的缩短的生存时间有关。由于淋巴细胞中的L1甲基化水平很高,因此更高的TIL密度可能导致包含癌细胞以及非肿瘤细胞(包括TIL)的癌组织中L1甲基化水平更高。TIL在L1甲基化水平和生存之间的关系中的假定相互作用促使探索肿瘤L1甲基化水平和TIL密度的组合状态作为GC中的预后指标。

方法: 研究人员分别使用CD3免疫组织化学和焦磷酸测序甲基化分析,对高级GC样品(n = 491)中的TIL和肿瘤L1甲基化水平进行了测量。在肿瘤中心和浸润区域测量TIL密度。

结果: TIL密度与肿瘤L1-甲基化水平相关,但该关系较弱。研究人员发现L1甲基化水平和CD3 TIL密度的组合状态在生存分析中具有统计学意义。多变量分析表明,组合状态和生存之间的关系是独立的。在独立的一组中,侵袭性前线组合状态的预后价值显着。

结论: 肿瘤L1甲基化水平与TIL密度相关。

Clinica Chimica Acta:以甲基化SDC2和SFRP2为基础的新型血浆型早期结直肠癌筛查检测方法

根据之前报道,甲基化SFRP2是一种非侵袭性的结直肠癌(CRC)检测的生物标志物,对早期CRC的敏感性相对较低。

Sci Transl Med:循环肿瘤DNA甲基化谱有助于结直肠癌的早期诊断及预后预测

血液循环肿瘤DNA(ctDNA)的检测是一种非侵入性的检查方法,如果我们知道每种癌症的正确标志物,则可在早期检测出癌症的存在。目前,ctDNA已成为多种癌症有用的诊断和预后生物标志物。现研究人员开展一项研究,以评估ctDNA甲基化标志物用于结直肠癌(CRC)的诊断和预后中的潜在应用,并通过一项前瞻性队列来验证其在筛查高CRC风险的患者中的有效性。研究人员首先通过比较CRC组织和正常血液白细胞来识别

Oncogene:FOXA1的高甲基化和 PTEN等位基因的缺失能够促进鳞状分化和膀胱癌异质性

膀胱癌中的瘤内异质性是进行准确分子分型和良好治疗效果的障碍。然而,肿瘤异质性的个体细胞和机制贡献是有争议的。最近,有研究人员调查了FOXA1和PTEN去激活在膀胱癌中的潜在机制,并探究了对肿瘤异质性的贡献情况。这些分析在去激活的FOXA1和PTEN中间型和腔型小鼠尿路上皮细胞中进行。研究发现,FOXA1和PTEN的去激活和表达减弱在人类疾病中广泛存在,且FOXA1和PTEN在等位基因缺失和位点特异
