概括
在多发性骨髓瘤 (MM) 中对利那利多米德的抗拒性并不依赖于剂量. 对于对标准或低剂量利那利多米德耐药的患者的结局显示了类似的无进展生存期,这表明了一致的耐药性模式.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 临床治疗学 临床治疗学
背景情况:
- 对利那利多米德的抗拒性在第一次复发时显著影响了多发性骨髓瘤 (MM) 的治疗决策.
- 莱纳利多米德剂量 (标准与低维护剂量) 对MM中耐药性发展的影响尚不清楚.
研究的目的:
- 为了评估和比较多发性骨髓瘤患者的治疗结果,耐药标准剂量与低剂量莱纳利多米德.
- 为了确定莱纳利多米德的折射性是否依赖于剂量.
主要方法:
- 复发性骨髓瘤患者接受列纳利多米德含有的一线治疗方案的回顾性审查.
- 对二线治疗和列纳利多米德再治疗的无进展生存期 (PFS) 和总生存期的评估.
主要成果:
- 在标准剂量和低剂量利那利多米德耐药的患者之间没有观察到PFS的显著差异 (两者的中位数为14个月).
- 耐火组的PFS明显低于非耐火组 (中位数为30个月).
- 在莱纳利多米德再处理和多变量分析中也发现了类似的趋势.
结论:
- 在多发性骨髓瘤中,莱纳利多米德的折射性并不取决于所服用的剂量.

Renal Failure: Dose Adjustments
88
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.

Combination Therapies and Personalized Medicine
4.9K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Rational Dosage Regimen: Maintenance Dose and Loading Dose
4.0K
A rational dosage regimen considers a drug's pharmacokinetics, including its absorption, distribution, metabolism, and elimination from the body. By understanding these factors, the appropriate dosage can be determined, and the dosing schedule can be designed to achieve and maintain the desired therapeutic effect while minimizing adverse effects.
In most cases, drugs are administered repetitively or infused continuously to maintain a steady-state concentration in the body. At a steady...

Targeted Cancer Therapies
7.6K
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.
