概括
神经内分泌前列腺癌 (NEPC) 包括各种亚型,包括侵袭性小细胞和大细胞NE癌. 治疗相关的NEPC是由雄激素缺乏引起的,需要积极的治疗和活检确认.
科学领域:
- 泌尿外科
- 癌症学
- 内分泌学
背景情况:
- 神经内分泌 (NE) 细胞存在于正常的前列腺和腺癌中,通过对分泌信号影响前列腺的生长.
- 在前列腺癌的发展和进展中发挥作用的NE细胞缺乏增殖活性和雄激素受体 (AR).
- 前列腺瘤与NE分化被分为五组,具有不同的临床意义和诊断作用.
研究的目的:
- 分类和描述不同类型的神经内分泌前列腺癌 (NEPC).
- 突出小细胞NE癌 (SCNEC) 和大细胞NE癌 (LCNEC) 的临床相关性和攻击性.
- 引入与治疗相关的NEPC (t-NEPC) 作为一个独立的实体,并强调需要在抵抗割的前列腺癌中进行后续活检.
主要方法:
- 对NE前列腺瘤现有文献和分类系统的审查.
- 在前列腺腺癌中免疫化检测NE分化.
- 对不同NEPC亚型的临床特征,预后和治疗影响的分析.
主要成果:
- NE前列腺瘤包括部分NE分化,帕内特细胞样分化,NE瘤/癌细胞 (NET),SCNEC和LCNEC.
- SCNEC 和 LCNEC 是具有攻击性,临床意义的瘤,预后不佳,需要密集治疗.
- 一个新的分类实体t-NEPC是由于缺少雄激素而出现的,其特点是AR损失和高增殖,需要积极治疗.
结论:
- 前列腺癌中神经内分泌的分化呈现出不同的亚型,具有不同的临床行为.
- 侵袭性NEPC亚型,特别是SCNEC,LCNEC和t-NEPC,需要迅速和密集的治疗策略.
- 随访活检对于在割耐药前列腺癌中识别t-NEPC等攻击性表型至关重要.

Neural Regulation
34.8K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Classification of Neurotransmitters
5.3K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

Sympathetic Division of the ANS
4.2K
The sympathetic division of the autonomic nervous system (ANS) plays a crucial role in preparing the body for stress, physical activity, and increased energy demands. This division activates the "fight-or-flight" response, enabling individuals to respond effectively to challenging situations.
Originating in the thoracic and lumbar spinal cord segments, the preganglionic fibers of the sympathetic division exit the spinal cord through the white ramus communicans. They then enter the...

Parasympathetic Division of the ANS
4.4K
The parasympathetic division of the autonomic nervous system (ANS) regulates rest and digestion functions in the body. It works in opposition to the sympathetic division, promoting relaxation, conservation of energy, and digestion. The parasympathetic division consists of preganglionic fibers originating from specific cranial nerves (III, VII, IX, X) and the sacral spinal nerves (S2-S4). These fibers synapse with postganglionic neurons in the terminal ganglia, innervating various organs and...
