简介:客观:借助于高分辨率图象分析(HRIA)预言食道的上皮的发育异常的结果。方法:无征状的成年人从Linxian县的Heshun公社在1983为食管的汽球细胞学被检查。93严重发育异常和食管的122温和发育异常被选择。借助于与电视照相机装备的一台Axiomat显微镜,在染色奶头的有鳞的上皮的中间的层的保存得很好的房间的100个正常原子核随机被检验。结果:93个cytologically诊断的严重发育异常盒子,24,14和7分别地在3,5和9年里进行了到癌。在另外的48个盒子中,发育异常仍然是马厩或regressed到正常。另外的盒子被用作控制。根据染色质特征,盒子的正确诊断被HRIA在75.0%完成(18/24),85.7%(12/14)并且(6/7)85.7%盒子检验了,分别地(P<0.001)。122cytologically诊断的温和发育异常,16,13和12个盒子分别地在3,5和9年里进行了到癌。另外的81个盒子仍然是马厩或regressed到正常。正确诊断被HRIA在93.8%做(15/16),76.9%(10/13)并且(10/12)833%盒子检验了,分别地(P<0.001)。结论:HRIA检验的染色质原子特征能预言癌症前期的损害的结果并且从non-progressor区别progressor。它能为chemo预防试用的效率的评估被用作代理人端点biomarkers。
简介:得到中央neurocytoma的更好的识别并且减少的目的错误诊断。回顾的评论识别了中央neurocytoma的15个盒子的方法。中央neurocytoma的所有情况为他们的临床的症状,病理学的变化,染色的immunohistochemical,预后和微分诊断被分析。临床列在后面在上面被执行。在那里的结果1064年是8男性和7女性(中部32.93年)。最普通的介绍症状是与增加的intracranial压力(ICP)有关的那些,包括头疼(100%),papilledema(93%)并且呕吐(80%)。所有肿瘤位于室的系统。肿瘤由一致房间组成与围着原子核和一个好染色质模式,并且在一些区域,有perinuclear光圈的小房间能被看见。特别地,无核的区域可以有一个好fibrillary矩阵(neuropil)。原子atypia和脉管的增长分别地出现在二种情况中。焦点的坏死能在一种情况中被看见。Immunohistochemical调查结果包括了synaptophysin(15/15)的表示,神经原特定的enolase(12/15)和glialfibrillary酸的蛋白质(GFAP)(3/15)。MIB-1增长索引从0.812.5%,并且在估计的15个盒子中的3个中是超过2%。11个病人的后续信息是可得到的。结论中央neurocytoma一般来说,但是在里面有有利预后一些情况,临床的功课能是好攻击的。GFAP确实,增长索引和脉管的增长的增加可能建议一个更恶意的过程。

简介:变形乳癌(MBC)被肿瘤生长,增长和变形前进的联合描绘并且典型地与辩解的目的被管理。标准全身的治疗的利益是相对有限的,疾病被认为医不好建议需要调查变形过程的各种各样的阶段的生物司机以便改进分子地驾驶的治疗的选择。察觉,枚举和传播肿瘤房间(CTC)的分子的分析提供一个吸引人的机会推进这知识。食物和药变清管理的CellSearch系统枚举的CTC在MBC病人是没有前进的幸存(PFS)和全面幸存(OS)的一个独立预示的因素。几份出版报纸为介绍了在血的7.5mL的基础CTC计数5的MBC病人表明了差的预后。因此,CTC的枚举在为MBC的治疗期间向一个工具提供比用常规放射学的测试的解剖评价的标准预定早预言疾病的前进的能力。在词法的变形过程癌症房间展览和phenotypic粘性经历epithelialmesenchymal转变(EMT)期间。这重要现象与被联系在上皮的标记的规定下面(例如,EpCAM)与在当前的CTC丰富方法的适用性的潜在的限制。在很多调查翻译的如此的观察瞄准了改进我们的能力枚举并且表现CTC的分子的描述。理论上,CTC的phenotypic分析能代表能对变形疾病识别一个新潜在的目标并且推进发展并且个性化的治疗监视的胸肿瘤的液体活体检视。
