概括
世卫组织第五版分类将垂体腺瘤重命名为垂体神经内分泌瘤 (PitNET). 这项研究发现 gonadotroph PitNET 占主导地位,在外科手术中没有乳腺培养性 PitNET,并突出了转移性 PitNET.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 世界卫生组织分类第五版 (WHO5) 更新了术语,将垂体腺瘤更名为垂体神经内分泌瘤 (PitNET).
- 这使PitNET命名与来自其他解剖部位的神经内分泌瘤 (NETs) 保持一致.
- 了解WHO5下的PitNET临床病理特征对于准确的诊断和治疗至关重要.
研究的目的:
- 根据WHO5分类,研究手术切除的PitNETs的临床病理特征.
- 分析PitNET亚型在手术队列中的分布.
- 评估法国五级分级系统对PitNET的有用性.
主要方法:
- 对210例手术切除和病理确认的PitNET病例 (2021-2023) 的回顾性分析.
- 使用法国五层分类系统对瘤进行分类.
- 对转移性PitNET病例的详细检查,包括组织病理学和临床过程.
主要成果:
- SF1系的PitNET,主要是阳性淋巴腺素 (FSH/LH),是最常见的亚型 (49.5%).
- 在这个外科手术队伍中,注意到缺乏乳性PitNET,这归因于医疗治疗.
- 法国分级系统的分布:1a (58.1%),1b (17.6%),2a (16.2%),2b (7.1%) 和3 (1.0%) 等级.
- 两例转移性皮质变质PitNET病例表现出侵略性行为和不良预后.
结论:
- 世界卫生组织5分类提供了有价值的见解PitNET亚型在手术队列中的分布.
- 观察到PitNET淋巴细胞的占主导地位和零细胞瘤的罕见性.
- 转移性PitNET病例表明预后不佳,需要进一步验证法国分级系统的预测价值.

The Pituitary Gland
6.1K
The pituitary is a small endocrine organ in the sphenoid bone under the hypothalamus. Primarily, the pituitary in adults has two distinct anatomical and functional regions— the anterior and posterior lobes. During human fetal development, a third pituitary gland region called the pars intermedia atrophies and disappears. However, some of its cells migrate and exist adjacent to the anterior pituitary in adults.

Hormones of the Pituitary Gland
6.1K
The small, pea-sized pituitary gland is located at the base of the brain. It is crucial in regulating various bodily functions, from growth to reproduction. The gland is divided into the anterior lobe and the posterior lobe. The secretory cell clusters in the pars distalis of the anterior pituitary lobe are controlled by hypothalamic regulators and synthesize six primary hormones.
The most abundantly secreted hormone from the anterior lobe is the growth hormone, which controls overall growth by...
