概括
这项研究发现,与其他结合策略相比,自主干细胞移植 (ASCT) 在多发性骨髓瘤中没有显著改善可测量的残留疾病 (MRD) 负面率. 在MRD导向的整合疗法中,MRD阴性和MRD阳性患者的结局相似.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 临床试验 临床试验
背景情况:
- 可测量的残留性疾病 (MRD) 是新诊断的多发性骨髓瘤的关键预后指标.
- 评估MRD引导的整合策略对于符合自主干细胞移植 (ASCT) 资格的患者至关重要.
研究的目的:
- 评估MRD指导的巩固策略在新诊断的多发性骨髓瘤患者中对可移植的新诊断患者的疗效.
- 为了比较基于诱导治疗后MRD状态的不同整合方法.
主要方法:
- 一项3期试验随机将患者分配到ASCT或伊萨图西马布,卡菲尔佐米布,莱纳利多米德和德克萨美沙 (Isa-KRd) 巩固,如果MRD阴性 (<10^-5).
- 阳性MRD患者被随机分配到协同ASCT或单个ASCT与Isa-KRd.
- 主要终点是维持治疗前的MRD阴性状态 (<10^-6).
主要成果:
- 在MRD阴性患者中,ASCT和Isa-KRd组显示了类似的MRD阴性率 (86%与84%对比),灵敏度为10^-6.
- 在MRD阳性患者中,双组ASCT和单组ASCT显示了相似的MRD阴性率 (32%对40%),灵敏度为10^-6.
- 没有发现新的安全问题;整合疗法一般耐受良好.
结论:
- 与MRD阴性髓瘤患者的Isa-KRd整合相比,ASCT并没有显著改善MRD阴性率.
- 与MRD阳性髓瘤患者的单个ASCT相比,Tandem ASCT并没有显著改善MRD阴性率.
- 该研究表明,MRD引导的整合策略可能不需要在多发性骨髓瘤中加强ASCT方法.

Treatment Resistant Cancers
3.4K
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...

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.
