概括
组织病理学特征,如瘤坏死和淋巴血管入侵 (LVI) 与冠状腺癌的预后有关. 这项研究确定了提高分级和预测5年生存率的关键标志物,以获得更好的患者结果.
科学领域:
- 在瘤学瘤学.
- 病理学 病理学 病理学
- 手术瘤学手术瘤学
背景情况:
- 分类软骨性瘤,如软骨肉瘤,提出了诊断上的挑战.
- 临床上需要一个以证据为基础的标签来标准化骨肉瘤分级.
- 传统的分级依赖于患者,瘤和治疗变量,因此需要对组织病理标志物的探索.
研究的目的:
- 为了确定与5年存活率相关联的冠状动脉瘤的特定组织病理特征.
- 为了比较组织病理学特征的预后价值与传统的患者,瘤和治疗变量.
- 开发一种以证据为基础的方法,用于对软骨肉瘤的预后评估.
主要方法:
- 对为原发性肌肉瘤进行手术切除的患者进行回顾性审查,随访时间至少为2年.
- 两个病理学家对所有瘤样本进行独立的组织病理学审查和评分.
- 使用卡普兰-梅尔和比例危险模型进行单变量和多变量分析,以评估与5年特定疾病生存率 (DSS) 和无疾病生存率 (DFS) 的关联.
主要成果:
- 包括51名患者,平均随访时间为49个月.
- 单变量分析显示,较高的线粒速率,瘤脱差,细胞性增加,异型性增加,淋巴血管侵袭 (LVI) 和较高的瘤亡与更糟糕的5年DSS有关.
- 在多变量分析中,只有较高的瘤亡仍然与疾病特异性存活率有显著的关联 (HR3.58,p=0.035);没有任何组织病理因素与DFS有显著的关联.
结论:
- 这项研究提供了证据,支持使用特定的组织病理学标记来评估冠状动脉瘤的预后.
- 瘤死亡和LVI成为与预后相关的重要因素,需要进一步调查.
- 这些发现有助于开发一种更强大的,以证据为基础的软骨肉瘤分级系统.

Tumor Progression
6.4K
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
6.7K
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...
