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：与女乳癌相比，男乳癌是稀罕疾病，并且在临床/病理学的特征和预后之间的关系争论，或甚至大部分未知。在这研究，我们从合用的男乳癌病人在天津医药大学癌症研究所和医院从1996年1月对待到2011年12月的109nonmetastatic用临床、病理学的数据执行了回顾的分析。木头等级测试证明那降低肿瘤舞台，没有淋巴节点参与，和积极雌激素/孕酮受体地位是没有疾病的幸存和外套的好预言者univariate分析上的幸存。然而，hormonotherapy仅仅是没有疾病的幸存，并且不全面幸存的一个好预兆的因素。另外，基于考克斯，比例的危险回归模型，仅仅淋巴节点参与，和雌激素/孕酮受体地位是multivariate分析上的统计上重要的预兆的因素。我们的结果证明尽管辅助全身的治疗在男乳癌广泛地被使用，病人和预后在最后几十年，淋巴节点参与，和雌激素/孕酮受体地位改善了仍然是最重要的预示的因素。有一种更大的样品尺寸的未来的多中心研究着急地被需要进一步理解男乳癌。

简介：AbstractBackground:Nipple discharge cytology is a simple non-invasive method that may provide valuable information for detecting underlying malignancy. Several studies have investigated the diagnostic value of cytology in breast cancer patients with pathological nipple discharge, but the results have been highly variable. Herein we presented a systematic review and meta-analysis of published studies pertaining to the diagnostic capacity of nipple discharge cytology in patients with breast cancer.Methods:A systematic literature search was performed (Medline/PubMed, Embase, Cochrane Library databases, and Google Scholar) to identify studies that investigated the diagnostic capacity of cytology with regard to breast cancer in patients with pathologic nipple discharge. Two independent researchers identified articles that assessed the sensitivity and specificity of cytological evaluation for breast cancer detection in patients with pathologic nipple discharge published between January 2000 and October 2018. Articles were only included in the meta-analysis if they met predetermined criteria. The characteristics of each study and the data they yielded were summarized. Quality assessment of all articles included was performed using the Methodological Index for Non-randomized Studies Criteria (MINORS) and the Quality Assessment of Diagnostic Accuracy Study 2 (QUADAS-2). Heterogeneity was tested via Cochran Q test and the I2 statistic using Stata 12.0 and Meta-DiSc 1.4 software, and meta-analysis was performed.Results:A total of 286 articles were identified, of which 12 articles including a total of 1476 patients were deemed eligible for inclusion in the meta-analysis. A random-effects model assessing the capacity of nipple discharge cytology to predict breast cancer yielded pooled sensitivity 63% (95% confidence interval [CI]: 53%-72%), specificity 95% (95% CI: 87%-98%), positive likelihood ratio 12.35 (95% CI: 4.87-31.34), and negative likelihood ratio 0.39 (95% CI: 0.30-0.50). The diagnostic odds ratio was 31.88 (95% CI: 11.30-89.98). The area under the summary receiver operating characteristic curve was 0.79 (95% CI: 0.75-0.82). Conclusion: The current meta-analysis suggests that nipple discharge cytology is a useful diagnostic modality for detection of breast cancer in patients with pathological nipple discharge, with moderate sensitivity and high specificity.
