概括
成年皮洛细胞性星细胞瘤 (APA) 的复发率为50%,受瘤位置和Ki-67指数的影响,而不仅仅是切除程度. 脑下瘤带来了更大的外科手术挑战,需要个性化,生物标志物引导的治疗策略.
科学领域:
- 神经瘤学神经瘤学
- 神经外科 神经外科
- 病理学 病理学 病理学
背景情况:
- 成人囊性星细胞瘤 (APA) 很少见,与儿科形式不同.
- 预后有所不同,对影响结果的因素的数据有限.
- 瘤特征和手术方法会影响复发和存活率.
研究的目的:
- 评估瘤体积,位置和患者年龄对APA预后的综合影响.
- 分析影响成年皮洛细胞性星瘤手术结果和存活率的因素.
- 确定在经过手术治疗的成年皮洛细胞性星细胞瘤中复发和死亡率的预测因素.
主要方法:
- 对手术治疗APA的32名成年患者 (2014-2023) 的回顾性分析.
- 对人口统计,成像,组织学和临床结果的检查.
- 瘤位置的相关性 (下垂体与上垂体) 和Ki-67指数与预后.
主要成果:
- 下腔瘤 (56%) 与较差的结果有关,包括较低的KPS和增加的手术并发症.
- 在下瘤 (33%) 和上瘤 (43%) 中,总切除率较低.
- 整体复发率为50%,由较高的Ki-67指数 (p<0.05) 显著预测;切除程度不是一个显著的预测因素. 在复发病例中,BRAF突变很少发生 (38%). 五年死亡率为6%,主要是高度星系细胞瘤与皮洛伊特征 (HGAP).
结论:
- 成年皮洛细胞性星细胞瘤可以有侵略性的临床过程,挑战良性假设.
- 下腔位置带来了独特的外科手术挑战,需要量身定制的管理.
- 个性化,以生物标志物为指导的治疗策略,专注于Ki-67,对于管理APA复发和改善结果至关重要.

Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Cancer Stem Cells and Tumor Maintenance
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...
