概括
在慢性淋巴细胞白血病 (CLL) 和小淋巴细胞淋巴瘤 (SLL) 患者中使用静止剂与改善的生存结果有关,包括整体生存和无进展生存. 这种关联适用于无论患者是否接受ibrutinib或其他当代疗法治疗.
科学领域:
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
- 临床试验 临床试验
背景情况:
- 慢性淋巴细胞白血病 (CLL) 和小淋巴细胞淋巴瘤 (SLL) 是具有不断变化的治疗景观的血液恶性瘤.
- 布鲁顿的氨酸激酶 (BTK) 抑制剂,如易布鲁替尼,代表了针对CLL/SLL的向治疗的重大进展.
- 之前的研究表明,他类药物可能会降低各种癌症的死亡率,但它们对CLL/SLL的影响,特别是BTK抑制剂的影响,尚不清楚.
研究的目的:
- 调查CLL/SLL患者的他类药物使用与生存结果 (总生存率,无进展生存率,癌症特异性生存率) 之间的关联.
- 评估这种患者群体中他类药物的使用与严重不良事件 (等级≥3) 的发生之间的关系.
- 确定他类药物的使用是否是接受当代治疗的CLL/SLL患者的独立预后因素.
主要方法:
- 分析了来自四项随机对照试验 (RESONATE, RESONATE-2, iLLUMINATE,HELIOS) 的个人参与者数据.
- 考克斯比例危险模型被用于评估基线他类药物使用和生存终点之间的关联.
- 使用后勤回归模型来检查他类药物使用与等级≥3不良反应之间的联系.
- 对多个临床和人口统计学共变量进行了调整.
主要成果:
- 在1467名患者中,424名 (29%) 在基线使用他类药物.
- 静止剂使用与改善的整体存活率 (aHR 0.55),无进展存活率 (aHR 0.73) 和癌症特异性存活率 (aHR 0.39) 显著相关.
- 这些好处在不同的治疗臂 (ibrutinib vs. non-ibrutinib) 和疾病诊断 (CLL vs. SLL) 中是一致的.
- 在他类药物使用和等级≥3的不良反应之间没有发现显著的关联.
结论:
- 立方体使用是CLL/SLL患者独立的积极预后因素,改善了生存结果.
- 对于使用他类药物的好处似乎在各种当代治疗方案中一致,包括基于ibrutinib的疗法.
- 需要进一步的研究来证实这些发现,并阐明他类药物对CLL/SLL的影响背后的机制.

Targeted Cancer Therapies

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.

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...
