背景情况:
- 默克尔细胞癌 (MCC) 经常复发并远程转移.
- 目前监控成像指南缺乏基于证据的支持.
- 了解转移模式对于早期检测和改善患者治疗结果至关重要.
研究的目的:
- 调查MCC中原发性瘤部位和初始远程转移之间的关系.
- 分析原发性瘤部位对转移时间,总生存率 (OS) 和MCC特异性死亡 (MSD) 的影响.
- 为基于证据的MCC监测策略提供信息.
主要方法:
- 对151名患有I-III阶段MCC的患者进行了回顾性分析,后者进展到IV阶段.
- 费舍尔的精确测试用于基于主要瘤部位的转移模式进行比较.

01:30Skin Cancer
4.1K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

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...
