In myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) with TP53 aberrations, dissecting the interaction amongst patient, disease and treatment factors are important for therapeutic decisions and prognostication. This retrospective analysis included patients with newly diagnosed MDS (>5% blasts) and AML with TP53 mutation(s) treated at MD Anderson Cancer Center. We factored patient age, TP53 aberration burden, therapy intensity and use of venetoclax in the AML subgroup, and allogeneic hematopoietic stem cell transplantation (HSCT) to interrogate outcomes. TP53 was annotated as high-risk (TP53HR) if >1 mutation, one mutation + allelic deletion or a single mutation with variant allele frequency (VAF) ≥40%; TP53 low risk (TP53LR) included a single TP53 mutation VAF.

TP53 畸变的临床询问及其对髓系肿瘤患者生存率的影响。



在骨髓增生异常综合征 (MDS) 和伴有 TP53 畸变的急性髓系白血病 (AML) 中,剖析患者、疾病和治疗因素之间的相互作用对于治疗决策和预后非常重要。本回顾性分析包括在 MD 安德森癌症中心治疗的新诊断 MDS (>5% 原始细胞) 和 TP53 突变的 AML 患者。我们考虑了患者年龄、TP53 畸变负荷、治疗强度和 AML 亚组中维奈克拉的使用,以及同种异体造血干细胞移植 (HSCT) 来询问结局。如果 >1 突变、一个突变 + 等位基因缺失或单个突变具有变异等位基因频率 (VAF) ≥40%,则 TP53 被注释为高危 (TP53HR);TP53 低风险 (TP53LR) 包括单个 TP53 突变 VAF。
