概括
这项研究发现,对于儿科尤宁肉瘤 (ES) 的非剂量密集化疗方案 (EFT-2001) 产生了相当的长期生存结果,尽管与间隔压缩化疗 (ICC) 相比,其效果不佳. 对于低收入和中等收入国家 (LMICs) 的资源有限环境,EFT-2001协议仍然是一个切实可行的选择.
科学领域:
- 儿科瘤学 儿科瘤学
- 医学瘤学 医学瘤学
- 临床试验 临床试验
背景情况:
- 间隔压缩化疗 (ICC) 是对尤文肉瘤 (ES) 的标准护理,但其在低收入和中等收入国家 (LMICs) 的适用性令人担忧.
- 在2013年1月至2017年6月期间,用于治疗意图的儿科ES患者 (<15岁) 使用非剂量密集化疗方案EFT-2001.
研究的目的:
- 以回顾性分析用EFT-2001非剂量密集化疗方案治疗尤宁肉瘤的儿科患者的长期结果.
- 将EFT-2001协议的结果与已建立的间隔压缩化疗 (ICC) 标准进行比较,特别是在资源有限的环境中.
主要方法:
- 对200名儿科患者 (<15岁) 患有尤文肉瘤 (ES) 的随访队列的回顾性分析.
- 从2013年1月到2017年6月,患者使用EFT-2001非剂量密集化疗协议进行治疗.
- 局部治疗在9-12周后进行;评估了长期结果,包括无事件生存 (EFS) 和整体生存 (OS).
主要成果:
- 在97个月的随访中位数,整个队列的7年EFS为55%,OS为69%.
- 局部化ES队列显示7年EFS为60%和OS为73%,而转移队列的7年EFS为37%,OS为53% (p=0.003,p=0.015).
- 不良结局与人环素剂量,轴性瘤位置,缺陷组织性缩和年龄较大有关. 心脏毒性影响了13%的患者.
结论:
- 尽管与ICC相比,EFT-2001非剂量密集化疗方案为儿科ES提供了相对公平的长期结果,但与治疗相关的死亡率较高.
- EFT-2001协议是对LMICs资源有限的环境的实际解决方案.
- 对于高风险的子集,ICC可以逐步分为LMIC,前提是有适当的支持性护理和营养康复计划.

Dense Connective Tissue

Dense connective tissue contains more collagen fibers than loose connective tissue. As a consequence, it displays greater resistance to stretching. There are two major categories of dense connective tissue— regular and irregular.
Dense Regular Connective Tissue
In dense regular connective tissue, fibers are arranged parallel to each other, enhancing its tensile strength and resistance to stretching in the direction of the fiber orientations. Ligaments and tendons are made of dense regular...

Predicting Reaction Outcomes
10.3K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Dose Size and Dosing Frequency: Determination Methods
281
Determining the optimal dose size and dosing frequency in pharmacotherapy is crucial for achieving therapeutic effectiveness while minimizing adverse effects. This article explores the methodologies employed in determining these parameters, focusing on their significance and interplay to tailor dosing regimens.Dose Size: Dose size refers to the amount of a drug administered in a single dose. It is determined based on the drug's pharmacodynamics and pharmacokinetics properties and...

Outcomes of Glycolysis
106.8K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Long-term Depression
33.2K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Determination of Multiple Dosing Parameters: Loading and Maintenance Doses
229
A loading dose is an essential pharmacological strategy to rapidly achieve the target plasma drug concentration necessary for an immediate therapeutic effect. This approach is especially critical for drugs characterized by slow absorption or extended half-lives, where delaying therapeutic plasma levels could compromise treatment outcomes. By administering a loading dose, clinicians ensure a prompt onset of drug action, even for agents with complex pharmacokinetic profiles.Achieving steady-state...
