概括
晚期转移性细胞癌 (RCC) 呈现出独特的瘤生物学特征,其特征是较少的攻击性特征和改善的生存率. 了解这些差异对于识别晚发RCC及其独特的预后影响至关重要.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 在瘤学瘤学.
- 癌症生物学 癌症生物学
背景情况:
- 细胞癌 (RCC) 的转移性潜伏机制尚不清楚.
- 区分早期转移与晚期转移对于理解RCC进展至关重要.
研究的目的:
- 调查早期和晚期转移性RCC之间的瘤生物学差异.
- 确定分离晚转移性RCC (晚期-mRCC) 的关键分子和组织病理特征.
主要方法:
- 对两个独立的RCC患者队列 (n=161和n=307) 的比较分析.
- 评估组织病理学特征,瘤生物学 (血管新生,炎症) 和基因组变化 (BAP1,PBRM1,SETD2).
- 在小鼠模型中评估瘤移植和患者生存结果.
主要成果:
- 与早期mRCC相比,晚期mRCC显示出有利的组织学 (清晰细胞,较低的阶段,低等级,较少的缩,较少的瘤状特征).
- 晚期mRCC瘤增加了血管生成和减少了炎症;BAP1损失不太常见.
- 晚期mRCC表现出较少的侵略性表型,具有较低的小鼠移植率和显著更长的转移后生存期.
结论:
- 晚期mRCC具有独特的生物学特征,其特点是具有不那么积极的表型和更好的预后.
- BAP1/PBRM1/SETD2状态和瘤缩是晚期mRCC的关键区分因素.
- 晚期mRCC和胰腺转移RCC之间的共同特征表明,共同的潜在生物学影响转移延迟和热流.

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 cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
