概括
新辅助辐射很少会缩小逆皮质肉瘤 (RPS),许多瘤的尺寸会增加. 这表明在手术前使用辐射来减小RPS时要谨慎.
科学领域:
- 在瘤学瘤学.
- 手术瘤学手术瘤学
- 辐射瘤学 辐射瘤学
背景情况:
- 逆皮质肉瘤 (RPS) 由于瘤大小和邻近器官的入侵,对完全切除手术提出了挑战.
- 新辅助辐射作为一种通过减少瘤尺寸来促进手术切除的策略正在被探索.
研究的目的:
- 为了研究新辅助放射治疗和瘤缩小在患有逆皮质肉瘤的患者之间的联系.
- 评估新辅助辐射对瘤大小和手术切除前RECIST反应的影响.
主要方法:
- 在2000年至2020年期间,对成年非转移性RPS患者进行了以治愈意向治疗的回顾性审查.
- 瘤大小变化的放射性评估 (绝对和相对) 和新辅助辐射前后的RECIST反应.
- 基于RECIST响应进行了子组分析.
主要成果:
- 在22名患者中,63.6%的患者经历了瘤减少 (平均7.1%的相对减少),而36.4%的患者没有变化或增加 (平均21.9%的相对增加).
- 根据RECIST标准,大多数瘤 (77.3%) 呈现稳定疾病;18.2% 呈现进展性疾病,大小显著增加.
- 在大多数情况下,新辅助辐射并没有改变器官支架或计划的多切除.
结论:
- 有利的RECIST反应和显著的瘤缩小在RPS的新辅助辐射中并不常见.
- 在新辅助疗法期间,显著的比例的RPS瘤增加了大小,挑战了其在手术前缩小规模的实用性.
- 研究结果表明,对于仅仅为了改变手术计划或实现瘤减少而使用RPS新辅助辐射,应谨慎使用.

Biological Effects of Radiation
17.5K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
385
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
