J Clin Oncol:遗传性肾肿瘤的生长速率:积极监测和干预的意义

2020-03-01 AlexYang MedSci原创

已经发表的积极监测的肾肿瘤生长速率中的大部分肿瘤均没有病理或者遗传数据。遗传性肾肿瘤的生长动力学仍旧不是很清楚。最近,有研究人员评估了遗传性肾肿瘤的生长速率以及与患者临床和遗传特性的相关性。研究共包括了292名患者,共453个遗传性肿瘤,包括了286个VHL缺陷性肿瘤、91个FLCN缺陷性肿瘤、52个MET缺陷性肿瘤和6个BAP1缺陷性肿瘤。研究发现,当使用遗传变异进行分层是,肿瘤生长速率(GR)

已经发表的积极监测的肾肿瘤生长速率中的大部分肿瘤均没有病理或者遗传数据。遗传性肾肿瘤的生长动力学仍旧不是很清楚。最近,有研究人员评估了遗传性肾肿瘤的生长速率以及与患者临床和遗传特性的相关性。

研究共包括了292名患者,共453个遗传性肿瘤,包括了286个VHL缺陷性肿瘤、91个FLCN缺陷性肿瘤、52个MET缺陷性肿瘤和6个BAP1缺陷性肿瘤。研究发现,当使用遗传变异进行分层是,肿瘤生长速率(GR)存在显著的差异。BAP1缺陷性肿瘤具有最快的GR均值(0.6cm/y;四分位差 [IQR], 0.57-0.68cm/y),其次是VHL缺陷性肿瘤(GR, 0.37cm/y; IQR, 0.25-0.57cm/y), FLCN缺陷性肿瘤 (GR, 0.10cm/y; IQR, 0.04-0.24cm/y)和MET激活肿瘤(GR, 0.15 cm/y; IQR, 0.053-0.32 cm/y; P<0.001)。来自于相同患者的肿瘤具有相似的GRs。更小的年龄单独与更高的GR相关(P=0.005)。

最后,研究人员指出,遗传变异不同,肿瘤生长速率不同。BAP1缺陷肿瘤的快速生长表明了这些患者应该谨慎治疗。肿瘤在较年轻患者中的快速生长可能需要更多的成像,而肿瘤生长较慢的患者可能需要更多的监测而非每年成像。

新式“萤火虫”手术可以精准切除肾肿瘤

最近,一种新型的手术方法将荧光绿染色、机器人技术和3D可视图像技术整合在一起,能够让外科医生精确切除肾肿瘤,从而避免因肿瘤切除整个肾脏。 以前肾肿瘤很难被诊断和定位,但是随着科技的进步,现在通过对健康组织染色和配备高分辨率摄像头的机器人手臂,已经攻克这一难题。 今年夏天伦敦南部的圣乔治医院首次实施了该手术。 泌尿科医师SteveBromage说:“这是很大的进步,新技术的价值得到了体现。外科

PLoS Med:肥胖相关因素在肾细胞肿瘤病因中的影响研究

一些肥胖相关的因素与肾细胞肿瘤(RCC)相关,但是是哪一个因素能够直接涉及到风险仍旧不清楚。最近,有研究人员利用遗传标记作为风险因素替代物,并且评估了这些标记与RCC风险的关系。研究人员鉴定了与肥胖测量、血压、脂肪、2型糖尿病、胰岛素和葡萄糖相关的遗传标记来作为工具变量,并在全基因组关联分析(GWAS)中与RCC风险的相关性进行了评估。研究包括了10784名RCC患者和20406名对照参与者。研究

Sci Rep:超敏超声微血管成像中的肿瘤血管生成无创性无对比3D评估

Nat Common:PBRM1可作为p53赖氨酸乙酰化的识别因子来抑制肾肿瘤的生长

P53乙酰化对其转录活性和肿瘤抑制功能的发挥是必不可少的。然而,对p53乙酰化识别蛋白的鉴定仍旧是不清楚的。PBRM1是肾癌中第二大高度变异的肿瘤抑制基因,编码PBRM1蛋白。最近,有研究人员鉴定了PBRM1是p53蛋白在第382位赖氨酸乙酰化(K382Ac)的识别因子,具体是通过其溴区结构域(BD4)来实现的。明显的是,BD4关键残基的变异能够干扰对p53的K382Ac识别。BD4的变异同样能够

肾肿瘤的分期对预后十分重要,此外淋巴结转移与不良预后有关。通常使用免疫组织化学和显微镜观察对淋巴结是否转移进行评估,这个过程十分耗时,并且可能漏掉微小转移。 我们对另一种检测前哨淋巴结(SNs)转移细胞的方法进行了评估。该方法基于流式细胞仪。 流式细胞仪是对细胞进行自动分析和分选的装置。它可以快速测量、存贮、显示悬浮在液体中的分散细胞的一系列重要的生物物理、生物化学方面的特征参量,并可
