研究目的: |
本研究拟在AML框架下从四个互补层面重新组织TP53相关信息:其一,在高可信体细胞变异子集内,将TP53置于患者内全部保留体细胞突变的排序背景中,以相对克隆位置比值表征其克隆支配程度;其二,在总体TP53突变AML队列中,整合17p缺失、TP53多体细胞突变及高VAF信息,构建疑似双等位失活评分;其三,将TP53 VAF作为连续变量进入模型并用限制性立方样条展示其与OS/CR的关系;其四,结合结构域、热点位点及LOF倾向开展功能影响分层。同时,以高可信体细胞子集对其余分析进行敏感性验证,以兼顾方法学严谨性与样本利用效率。 |

Objectives of Study: |
This study proposes to reorganize TP53-related information within the AML framework from four complementary perspectives. First, within the high-confidence somatic variant subset, TP53 will be placed in the ranking context of all retained somatic mutations within each patient, and its clonal dominance will be characterized using a relative clonal position ratio. Second, in the overall TP53-mutated AML cohort, 17p deletion, multiple somatic TP53 mutations, and high VAF information will be integrated to construct a suspected biallelic inactivation score. Third, TP53 VAF will be incorporated into the model as a continuous variable, and restricted cubic splines will be used to illustrate its relationship with OS and CR. Fourth, functional impact stratification will be performed by integrating protein domain location, hotspot sites, and loss-of-function tendency. Meanwhile, the high-confidence somatic subset will be used for sensitivity validation of the remaining analyses, thereby balancing methodological rigor with efficient use of the available sample size. |
