概括
MAGIC复合反应 (MCR) 整合了生物标志物和临床数据,以更好地预测急性移植对宿主疾病 (GVHD) 患者的生存率,而不是单独临床反应. 这一新指标提高了识别那些将实现长期GVHD控制和生存的患者的准确性.
科学领域:
- 血液学 血液学 血液学
- 免疫学 免疫学 免疫学
- 在瘤学瘤学.
背景情况:
- 目前对急性移植对宿主病 (GVHD) 治疗反应的评估依赖于临床症状.
- 此前,MAGIC联盟建立了MAGIC综合评分 (MCS),将血清生物标志物和治疗开始时的临床症状整合起来,以改善预测.
- 在以后的时间点 (28日) 结合生物标志物和临床数据来预测结果的实用性尚未完全阐明.
研究的目的:
- 评估28日 (D28) 将血清生物标志物与临床症状相结合是否能比单独临床反应 (CRO) 更好地预测非复发性死亡率 (NRM).
- 为了定义一个新的复合响应指标,MAGIC复合响应 (MCR),基于D28评估.
- 验证MCR对6个月NRM的预测准确性及其与CRO相比重新分类患者的能力.
主要方法:
- 分析了1135名接受急性GVHD系统治疗的患者的数据.
- 在D28.28上开发第四个MCS类别,用于症状消失和低风险生物标志物患者.
- 使用分类和回归树 (CART) 模型来定义MCR (MCS 0或MCS 1在D28),预测6个月的NRM.
- 在单独的队列中 (n=309) 使用AUC,负预测值和正预测值验证MCR与CRO的验证.
主要成果:
- 在验证队列中,MCR在6个月NRM的预测优于CRO (AUC:0.77对0.69;P=0.014).
- MCR显示了比CRO更高的负和正预测值.
- MCR将13%的临床响应者重新分类为非响应者,NRM高5倍,30%的临床非响应者被重新分类为响应者,NRM低6倍.
结论:
- MAGIC复合反应 (MCR) 是一个比单独临床反应更准确的6个月非复发死亡率预测器.
- MCR有效地重新分类患者,更准确地识别响应者和不响应者.
- 在未来的临床试验中,MCR作为长期GVHD控制和生存的优越代用终点.

Combination Therapies and Personalized Medicine
5.1K
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...

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...
