概括
前列腺癌中双边精液囊侵入 (SVI) 强烈预测淋巴结转移和不良结果. 了解SVI横向性有助于风险分层,以更好地管理患者.
科学领域:
- 尿道病学
- 癌症学
- 病理学
背景情况:
- 前列腺腺癌 (PCa) 中的精液囊泡侵袭 (SVI) 是一个高风险指标.
- SVI与淋巴结 (LN) 转移和较差的患者结果有关.
- 对于SVI横向性对LN转移模式的具体影响尚不清楚.
研究的目的:
- 调查精液囊侵入 (SVI) 侧向性和淋巴结 (LN) 转移之间的关系.
- 评估SVI侧向对节点负荷,转移焦点大小和节外延伸 (ENE) 的影响.
- 确定SVI横向性是否是PCa中不良结果的独立预测因素.
主要方法:
- 对225名患有SVI的PCa患者进行了前列腺切除和LN剖析的回顾性分析.
- 评估SVI横向性,瘤等级,体积和节点参数之间的关联.
- 使用单变量和多变量统计模型来分析数据.
主要成果:
- 43. 1% 的患者患有LN转移;双边SVI显著增加了LN转移的几率 (OR=2. 01),结节负担 (IRR=1. 89) 和ENE (OR=3. 76).
- 瘤体积和等级独立预测了LN转移,并与转移焦点大小和结节负担相关.
- 单边SVI主要导致双边LN传播 (61.1%),而双边SVI增加了双边传播的风险 (OR=3.81).
结论:
- 双边SVI是LN转移,节点负担增加和PCa中ENE的重要独立预测因素.
- SVI的横向性与特定的LN传播模式相关,为改善风险分层提供了潜力.
- 需要进一步的研究来验证SVI横向性在风险评估中的临床效用.

Metastasis
5.7K
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...

Disorders of the Male Reproductive System

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....
