まとめ
一般的な小児がんである神経芽腫は、多様な挙動を示し、国際神経芽腫病理分類(INPC)を用いて分類されます。このレビューでは、その病理、疫学、およびリスク要因、そして新興のAI応用について詳述します。
科学分野:
- 小児腫瘍学
- 腫瘍生物学
- 組織病理学
背景:
- 神経芽腫は、小児で最も一般的な頭蓋外固形腫瘍であり、乳児における新生物性疾患の主な原因です。
- 末梢神経芽腫腫瘍(pNT)は、神経芽細胞から発生する神経芽腫、神経節芽細胞腫、および神経節細胞腫を含みます。
- pNTは、自発的退縮から攻撃的な進行まで、多様な臨床的挙動を示し、異なる生物学的サブグループを示唆しています。
研究 の 目的:
- 末梢神経芽腫腫瘍(pNT)に関する包括的なレビューを提供すること。
- 国際神経芽腫病理分類(INPC)の概要を説明し、予後因子について議論すること。
- AI支援システムを含む、神経芽腫の診断とリスク層別化の進歩を探求すること。
主な方法:
- 神経芽腫の病理、疫学、および臨床的特徴に関する既存の文献のレビュー。
- 神経芽腫診断のための生検技術(コア針対従来法)の議論。
- 年齢、臨床病期、および分子/遺伝的マーカーを含む予後因子の分析。
主要な成果:
- 国際神経芽腫病理分類(INPC)は、pNTを分類するための主要なシステムです。
- 診断時の年齢、臨床病期、および分子/遺伝的要因は、リスク分類システムにおいて重要です。
- 特定の分子異常は、非常に攻撃的な神経芽腫サブタイプに関連しています。
結論:
- 神経芽腫の管理には、正確な分類とリスク層別化が不可欠です。
- 分子の詳細を含む多様な予後因子の理解は、治療戦略を改善します。
- 人工知能は、神経芽腫の病理分類を強化する可能性を秘めています。

Peripheral Nervous System: Ganglia and Nerves
5.5K
The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

Peripheral Artery Disease I: Introduction
378
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Tumor Immunotherapy
1.9K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Tumor Progression
7.4K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The Tumor Microenvironment
7.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Peripherally and Centrally Acting Muscle Relaxants: A Comparison
4.5K
Skeletal muscle relaxants can target the central nervous system [CNS] to reduce muscle tension or act directly at the neuromuscular junction to induce temporary paralysis. These two classes of muscle relaxants are called centrally acting muscle relaxants and peripherally acting muscle relaxants. They differ in their action, mechanism, administration route, and clinical uses.
Centrally acting muscle relaxants can be further divided into spasmolytic and antispasmodic drugs. Spasmolytic...
