概括

这项研究验证了两种遗传标记,rs1883112和rs1800871,作为R-CHOP化疗治疗扩散性大B细胞淋巴瘤 (DLBCL) 患者耐药性的预测因素. 这些发现可能会改善DLBCL的预后评估.

科学领域:

在瘤学瘤学.
药物遗传学药物遗传学
遗传学是一个遗传学.

背景情况:

扩散性大B细胞淋巴瘤 (DLBCL) 是最常见的非霍奇金淋巴瘤 (NHL).
对R-CHOP化疗的耐药性影响着30%-40%的DLBCL患者.
宪法遗传学可能预测R-CHOP耐药性.

研究的目的:

验证先前识别的单核酸多态 (SNPs) 作为DLBCL中R-CHOP耐药性的预测因素.
评估这些SNP在DLBCL患者的预后价值.

主要方法:

研究了20个参与R-CHOP药理动力学/药理动力学或病理生物学的SNP.
在多机构的药物遗传学研究中分析了185名DLBCL患者的数据.
根据修订的国际预测指数 (R-IPI) 进行了多变量分析和子组分析.

主要成果:

在rs2010963 (VEGFA) 和性别,rs1625895 (TP53) 和阶段之间发现了相关性.
rs1883112 (NCF4) 和rs1800871 (IL10) 显示出一致的效果,增加了进展和死亡的风险.
这两个SNP进一步区分了R-IPI-1-2患者的无进展生存 (PFS) 和整体生存 (OS).
具有罕见等位基因的患者的PFS和OS较短.

结论:

验证了rs1883112和rs1800871作为DLBCL对R-CHOP耐药性的预测因素.
这些SNP可以进一步区分R-IPI-1-2患者的预后.
在未来的试验中,应考虑宿主遗传学进行全面的DLBCL患者结果评估.

Comparing Copy Number Variations and SNPs

Comparing Copy Number Variations and SNPs

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
