TP53 mutated acute myeloid leukemia (AML) responds poorly to chemotherapy and has a short overall survival rate with a median of 5-9 months. Poor outcomes in TP53 mutated AML following chemotherapy have been observed and treatment options remain limited, although the presence of TP53 mutations alone should not be a barrier to therapy. Decitabine is emerging as an alternative treatment option for patients with TP53 mutated AML, although the agent has not been associated with deep molecular remissions and requires additional consolidation. The clinical and genomic characteristics of TP53 mutated AML are reviewed in this paper.
TP53基因发生突变的急性髓系白血病(AML)对化疗反应不佳,总生存率较低,中位生存期为5至9个月。尽管单独存在TP53突变不应成为治疗的障碍,但化疗后TP53基因发生突变的AML患者预后较差,且治疗选择仍然有限。地西他滨正在成为TP53基因发生突变的AML患者的一种替代治疗选择,尽管该药物尚未与深度分子缓解相关联,且需要额外的巩固治疗。本文对TP53基因发生突变的AML的临床和基因组特征进行了综述。
