概括
在手术期间的起源部位 (STO) 评估对脑髓母细胞瘤 (MB) 分子组的预测价值有限. 虽然它对SHH-MB和非WNT/非SHH MB有用,但对WNT-MB预测的准确性较低.
科学领域:
- 儿科神经瘤学 儿童神经瘤学
- 发育神经生物学的发展神经生物学
- 手术瘤学手术瘤学
背景情况:
- 脑髓母细胞瘤 (MB) 分子组 (WNT,SHH,非WNT/非SHH) 的发展起源不同.
- 假设WNT-MB起源于胚胎下罗姆巴唇 (LRL).
- 据认为,SHH-MB和其他MB类型来自小脑前体矩阵区域.
研究的目的:
- 分析儿科骨髓母细胞瘤的手术内源部位 (STO) 数据.
- 为了将手术内确定的STO与MB分子组的假设胚胎起源区域进行比较.
- 评估神经外科检查对MB分子分类的预测价值.
主要方法:
- 追溯审查了1996年至2020年间手术的58例儿科MB病例.
- 分析详细的操作报告,手术视频和临床/遗传数据.
- 基于手术内神经外科发现的STO评估.
主要成果:
- 在手术内评估的STO正确预测了20%的WNT-MB,60%的SHH-MB和71%的非WNT/非SHH MB中的分子组.
- 对STO的积极预测值为WNT-MB的0.21,SHH-MB的0.86,非WNT/非SHH MB的0.73.
- 神经外科检查显示,在预测脑髓母细胞瘤分子组的准确性有限.
结论:
- 在手术中观察到的STO对于确定脑髓母细胞瘤的分子组具有有限的预测值.
- 准确的MB分子亚型可能需要超出手术内外科评估的方法.
- 需要进一步的研究来完善在手术期间预测MB分子组的方法.

02:07Tumor Progression
6.3K
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...

02:21Cancers Originate from Somatic Mutations in a Single Cell
12.0K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

01:20The Retinoblastoma Gene
4.1K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
