概括
实现R0切除 (没有瘤细胞在边缘) 对于改善儿科突肉瘤的结果至关重要. 首次或重复手术的负边际提高了生存率,如果无疾病,则边缘<5mm是可以接受的.
科学领域:
- 儿科瘤学 儿科瘤学
- 手术瘤学手术瘤学
- 肉瘤研究研究 肉瘤研究
背景情况:
- 突肉瘤是儿童常见的软组织肉瘤.
- 目前的指导方针对最佳切除边缘和重新切除的必要性缺乏明确性.
- 这项研究解决了这些差距,通过评估边际充足度和重新切除对儿科突肉瘤结果的影响.
研究的目的:
- 为了确定儿科突肉瘤的适当切除边缘.
- 评估重新切割在预测患者结果中的作用.
- 评估边际状态对无事件生存 (EFS) 和整体生存 (OS) 的影响.
主要方法:
- 这是一项对36名儿科患者 (<18岁) 进行的回顾性队列研究,这些患者患有局部突肉瘤.
- 收集的数据包括人口统计,治疗和手术边缘状态 (R0与R1).
- 结果 (EFS,OS) 根据切除边缘和再切除状态进行了比较.
主要成果:
- 与R0切除相比,R1切除与复发或死亡的可能性明显更高.
- 在R0患者之间没有观察到EFS或OS的显著差异,边际<5mm与>5mm.
- 在初始或重新切除时具有正边缘 (R1) 的患者的生存状况明显比具有R0切除的患者更差.
结论:
- R0切除是改善儿科突肉瘤整体存活率和无事件存活率的独立预测因素.
- 实现负边际,无论是在初始切除还是再切除后,都与更好的结果有关.
- 对于R0患者来说,再切除和边缘<5mm是可以接受的,这表明完全的微观疾病移除是关键.

Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...
