概括
结合放射-223 (Ra-223) 治疗的骨修饰剂 (BMA) 改善了骨转移性割抵抗性前列腺癌 (CRPC) 患者的治疗结果. 使用BMA与症状骨事件 (SSE) 的风险降低有关.
科学领域:
- 在瘤学瘤学.
- 放射性药物疗法是一种放射性药物疗法.
- 骨转移管理 骨转移管理
背景情况:
- -223 (Ra-223) 二化物疗法改善了存活率,并延迟了骨癌 (CRPC) 的割抵抗性前列腺癌 (CRPC) 的症状性骨事件.
- 已知骨修饰剂 (BMA) 可以减少骨转移患者的SSE.
- 关于BMA和Ra-223治疗的联合使用的数据有限.
研究的目的:
- 在接受放射-223 (Ra-223) 治疗的骨转移性CRPC患者中,研究骨修饰剂 (BMA) 对症状骨事件 (SSE) 的影响.
- 评估现实世界的实践模式和结果.
主要方法:
- 追溯研究包括73名在10个日本机构接受Ra-223治疗的患者.
- 卡普兰-梅尔法用于估计到第一次SSE的时间; 群组比较的日志级别测试.
- 单变量分析以确定变量与SSE之间的关联.
主要成果:
- 总共有12名 (16.4%) 患者在12.7个月的中位随访期间经历了SSE.
- 骨修饰剂 (BMA) 的使用与有利的无SSE生存率 (HR 0.23,p=0.027) 有显著的关联.
- 在接受BMA的患者中,症状性病理性骨折发生的频率较低 (4.7%对23.3%,p=0.017).
结论:
- 骨修饰剂 (BMA) 的使用对于接受放射-223 (Ra-223) 治疗的抗割前列腺癌 (CRPC) 和骨转移患者很重要.

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Osteoclasts in Bone Remodeling
3.0K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...
