概括

与标准成人治疗方案相比,儿童化学疗法显著减少了中枢神经系统 (CNS) 复发. 这一发现为改善中枢神经系统复发的ALL患者的治疗结果提供了有希望的策略.

科学领域:

癌症学
血液学
临床试验

背景情况:

中枢神经系统 (CNS) 复发是成人急性淋巴细胞白血病 (ALL) 的重大挑战,往往导致患者的治疗结果不佳.
特别是在中枢神经系统的外骨性复发是成年ALL患者常见的和令人担忧的事件.

研究的目的:

评估儿童化学疗法方案在成人ALL患者中减少中枢神经系统复发的疗效.
通过标准成人疗法治疗的成人患者与以儿科疗法治疗的儿童患者之间的中枢神经系统复发率进行比较.

主要方法:

分析了一组新诊断的1005名成年ALL患者.
患者接受过超CVAD成人疗程 (n=596) 或PDT- ALL-2016儿童疗程 (n=409).
在两组治疗中对中枢神经系统复发的累积发病率进行了比较.

主要成果:

与成人治疗组 (11. 24%) 相比,儿童治疗方案的复发率较低 (7. 09%).
这种差异具有统计学意义 (p=0. 025).
即使在高风险患者中,儿科启发的治疗方案也显示出5年累计中枢神经系统复发发病率显著降低 (6. 75%与13. 7%,p=0. 003).

结论:

儿童化学疗法可能是成人ALL中中枢神经系统复发的保护因素.
这些发现表明,适应儿科治疗方案可以改善成年ALL患者的治疗结果,特别是在中枢神经系统受影响方面.
这项研究强调了成人ALL治疗策略的潜在转变,以减轻中枢神经系统复发风险.

Treatment Resistant Cancers

Treatment Resistant Cancers

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...

Factors Affecting Drug Response: Overview

Factors Affecting Drug Response: Overview

When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

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...
