概括
在早期细胞癌 (RCC) 中同步转移 (SM) 不常见,但存在挑战. 初级瘤切除可以改善孤立转移的存活率,特别是在肺部病例中.
科学领域:
- 在瘤学瘤学.
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 医疗成像医学成像
背景情况:
- 细胞癌 (RCC) 的发病率上升归因于通过成像增加的偶然检测.
- 在cT1aRCC (小于4厘米的原发性瘤) 中同步远程转移 (SM) 很少发生,但会影响生存和治疗决策.
- 需要了解SM的T1a RCC的临床特征,转移模式和结果.
研究的目的:
- 调查T1a RCC和SM患者的临床特征,转移模式,治疗和生存结果.
- 分析原发性瘤切除和全身治疗对T1a RCCSM死亡率的影响.
- 评估转移切除术在特定孤立转移部位中的作用.
主要方法:
- 来自国家癌症数据库 (2004-2019) 的263,911名T1a RCC患者的回顾性分析.
- 使用Cochran-Armitage测试和多变量分析进行SM预测因子和治疗影响的趋势分析.
- 基于转移部位和治疗方式的Kaplan-Meier对生存结果的分析.
主要成果:
- 在cT1a RCC患者中有2.0% (2275/114,661) 患有MS;这一比例每年下降不显著.
- 最常见的转移部位:骨 (59%),肺部 (35%),肝脏 (16%),大脑 (12%).
- 初级瘤切除和全身治疗降低了死亡率,特别是在肺部仅转移的转移中. 转移切除术改善了仅脑转移的存活率.
结论:
- 在T1a RCC中MS是不常见的,但在临床上是显著的,骨头是主要的转移部位.

5.5K
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...

6.2K
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...

02:17The Tumor Microenvironment
6.5K
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...
