概括
直接口服抗凝剂 (DOAC) 越来越多地被推用于与癌症相关的血栓形成 (CAT). 这项研究发现,大多数CAT患者仍然接受低分子量肝素 (LMWH),但随着罕见的出血事件,DOAC的使用正在增加.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 国际指导方针提倡直接口服抗凝剂 (DOAC) 作为癌症相关血栓形成 (CAT) 的第一线治疗.
- 目前关于CAT患者当前治疗模式和遵守指南的数据有限.
- 这项研究解决了对抗凝血剂使用和CAT的结果理解的差距.
研究的目的:
- 在被诊断患有癌症相关血栓症 (CAT) 的患者中研究抗凝剂治疗方式.
- 确定接受CAT抗凝剂治疗的患者出血事件的发病率.
- 分析采用DOACs与CAT的传统抗凝剂的趋势.
主要方法:
- 在2005年至2020年期间,对842名癌症活跃患者 (≥18岁) 和首次静脉血栓塞栓症 (VTE) 进行了回顾性分析.
- 数据来源于奥斯特福德L.医院静脉血栓症注册表的数据.
- 结果措施包括抗凝剂治疗模式和重大和临床相关非重大出血 (CRNMB) 的发病率.
主要成果:
- 低分子量肝素 (LMWH) 是85.8%的患者的初始抗凝剂,而DOACs被7.7%和维生素K对抗剂被6.5%使用.
- 对于初始治疗的DOACs的处方从3.0% (2013/2014) 显著增加到18.0% (2019/2020).
- 大型出血的发病率为每100人/年6.9,而CRNMB的发病率为每100人/年10.1.
结论:
- 对于CAT,主要的初始处理仍然是LMWH,但正在向DOAC发生明显的转变.
- 在CAT患者中,与抗凝剂治疗相关的出血并发症不常见.
- 观察到的出血率与主要临床试验中报告的出血率相当,这表明安全性概况有利.

Disorders of Hemostasis
885
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Esophageal Varices-II: Clinical Features and Management
60
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
