概括

在乳头甲状腺癌 (PTC) 中的VII级淋巴结转移与较差的生存率有关. 这一发现表明,需要对这种特定转移的PTC患者进行修订的分期和管理策略.

科学领域:

在瘤学瘤学.
手术病理学手术病理学
癌症研究癌症研究

背景情况:

在乳头甲状腺癌 (PTC) 中的第七级淋巴结转移 (LNM) 从N1b重新分类到N1a,这引发了对其预后意义的质疑.
关于VII级LNM对PTC患者癌症特异性存活率 (CSS) 的影响的证据有限.

研究的目的:

为了研究7级LNM在患有乳头甲状腺癌的患者的CSS上的预后影响.
确定与PTC中VII级LNM存在相关的风险因素.

主要方法:

在监测,流行病学和最终结果 (SEER) 数据库 (2004-2015) 中分析了40371名PTC患者的数据.
评估节点群 (N0,N1a,N1b和VII) 对CSS的影响,使用Cox和Fine-Gray模型估计危险比率 (HR) 和95%置信区间 (CI).
后勤回归分析以确定VII级LNM的风险因素.

主要成果:

在2.0%的PTC患者中发现了VII级转移,并与更具侵略性的临床病理特征和密集治疗有关.
多变量考克斯分析表明,VII级LNM与最差的CSS有显著的相关性 (针对VII的调整HR与N0:5.67).
在N0和VII组之间调整后的10年生存率差异为2.97%. 独立的危险因素包括年轻年龄,男性性别,白人种族,大瘤大小,甲状腺外延伸和多焦点性.

结论:

在PTC中,VII级LNM代表了一种独特的临床实体,其特点是侵略性行为和不良预后.
这些发现表明需要量身定制的临床管理策略,并对目前的N分期系统进行潜在的修订,用于PTC患者的VII级LNM.

Hyperthyroidism II: Pathophysiology

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...

Graves Disease II: Pathophysiology

Graves Disease II: Pathophysiology

Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
