概括
辅助放射治疗可以改善三阴性乳腺癌 (TNBC) 的老年患者的生存率. 在接受放射治疗的老年TNBC患者中,这项元分析发现了更好的5年整体存活率.
科学领域:
- 癌症学
- 放射治疗研究
- 老年医学
背景情况:
- 三重阴性乳腺癌 (TNBC) 具有独特的挑战,特别是在老年人 (≥65岁).
- 在老年TNBC患者中辅助放射治疗的作用仍然是活跃的研究领域.
- 现有证据有限,需要对现有数据进行全面审查.
研究的目的:
- 对TNBC老年患者辅助放射治疗的益处进行首次元分析.
- 评估放射治疗对这一群体的整体存活率和特定癌症存活率的影响.
- 综合相关临床研究的发现,以制定治疗策略.
主要方法:
- 对随机对照试验,非随机对照试验和队列研究进行了医学文献的系统搜索.
- 研究包括接受或未接受放射治疗的65岁以上的TNBC患者.
- 在2015年至2019年期间发表的四项队列研究,涉及10,710名患者,有资格进行元分析.
主要成果:
- 接受放射治疗的患者 (n=6283/8526) 的5年整体存活率显著提高 (77%对55%,p<0. 001).
- 添加放射治疗与癌症特异性生存率的改善有关 (n=815/1957).
- 来自大型回顾性研究的多变量分析表明,当与乳腺保护手术相结合时,放射治疗可能会提高整体和无疾病生存率.
结论:
- 辅助放射治疗似乎有助于改善TNBC的老年患者的整体存活率.
- 这些发现支持将放射治疗作为诊断TNBC的老年人治疗方案的一部分.
- 进一步的研究可能会澄清这种特定患者群体的最佳放射治疗策略.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
167
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...

Targeted Cancer Therapies
7.8K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Treatment Resistant Cancers
3.4K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
