概括
较低的阿姆鲁比辛初始剂量可以改善老年患者耐药性,复发性小细胞肺癌 (SCLC) 的无进展生存率. 这种方法也可以减少由于这种脆弱人群的不良事件而导致的治疗中止.
科学领域:
- 在瘤学瘤学.
- 老年医学 老年医学
- 药理学 药理学是指药理学的学科.
背景情况:
- 阿姆鲁比辛单疗法在日本用于耐火性,复发性小细胞肺癌 (SCLC).
- 临床指南缺乏针对老年SCLC患者的具体初始剂量建议.
- 这项研究解决了对耐火性,复发性SCLC的老年患者适当安鲁比辛剂量的需求.
研究的目的:
- 为了探索适合的阿姆鲁比辛初始剂量老年患者 (≥70岁) 耐火性,复发性SCLC.
- 为了比较低剂量 (<40 mg/m2) 和高剂量 (≥40 mg/m2) 的安鲁比辛治疗方案之间的结果.
- 在这个患者群体中确定影响治疗有效性和安全性的因素.
主要方法:
- 对47名患有不耐药性,复发性SCLC的老年患者进行了回顾性分析,这些患者接受了阿姆鲁比辛单独治疗.
- 患者分为低剂量 (<40 mg/m2) 和高剂量 (≥40 mg/m2) 的初始安鲁比辛组.
- 两组之间的无进展生存 (PFS),总生存 (OS) 和不良事件的比较.
主要成果:
- 与高剂量组相比,低剂量组 (3.64个月) 的中位数PFS显著更长 (1.5个月;P=0.04).
- 两组之间没有观察到OS的显著差异 (10.18个月与8.18个月;P=0.58).
- 在高剂量组 (44.4%) 与低剂量组 (13.5%) 之间,由于不良事件而停止治疗的比例较高,具有显著的非传染性毒性.
结论:
- 在老年SCLC患者中,较低的初始安鲁比辛剂量可能与改善PFS和减少中止治疗有关.
- 血液学和非传染性不良事件可能会对更高剂量的PFS产生负面影响.
- 建议对老年患者考虑低剂量安鲁比辛,花细胞殖民地刺激因子支持,并对毒性进行警监测.

Treatment Resistant Cancers
3.7K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Drug Dosing: Geriatric Patients
228
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
238
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Cardiomyopathy IV: Restrictive Cardiomyopathy
472
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
229
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
