骨髓质疏松症候群 (MDS) 的管理根据风险对患者进行分层. 虽然治疗改善了较低风险的MDS的生活质量,但高风险的MDS仍然需要更好的治疗方法来延长存活时间和预防急性髓性白血病.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 内部医学 内部医学
背景情况:
- 骨髓发育综合征 (MDS) 是一种具有不同临床表现和预后的克隆性造血干细胞疾病.
- 风险分层使用国际预测评分系统 - 修订和分子国际预测评分系统指导管理.
- 较低风险的MDS专注于症状管理和生活质量,而较高风险的MDS旨在延长生存时间并防止进展为急性髓性白血病 (AML).
研究的目的:
- 审查目前的骨髓质疏松综合征 (MDS) 治疗环境.
- 为提供MDS临床开发中的新型治疗剂的概述.
- 突出MDS管理中的持续挑战和未来方向.
主要方法:
- 对低风险和高风险MDS的当前治疗策略的审查.
- 讨论标准护理治疗,包括高风险MDS的低甲基化剂.
- 检查正在进行的临床试验和MDS新兴疗法.
主要成果:
- 目前对较低风险的MDS的治疗方法包括红色受体刺激剂,luspatercept,lenalidomide和imetelstat.
- 低甲基化剂单疗仍然是高风险MDS的标准,正在调查的新组合,但尚未超过生存益处.
- 尽管取得了进展,但仍然存在对有效疗法的大量未满足需求,尤其是在高风险的MDS患者的第一线治疗失败后.
结论:
- 管理MDS需要基于风险分层的定制方法.
- 新型药物和治疗组合正在积极研究,以改善高风险MDS的结果.
- 对生物标志物导向和免疫治疗方法的进一步研究对于推进MDS治疗范式至关重要.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
Principles of Drug Action
Drugs can be agonists or antagonists. Like the endogenous ligands, agonists always bind and activate the target to produce a cellular response. Agonist binding induces a conformational change which in turn...
