The Prognostic Value of TP53 Mutations in Adult Acute Myeloid Leukemia: A Meta-Analysis.
Objective: Mutations of the tumor protein p53 (TP53) gene were considered to be associated with an unfavorable prognosis in acute myeloid leukemia (AML). This meta-analysis aimed to systematically elucidate the prognostic value of TP53 mutation in adult patients with AML.
Method: A comprehensive literature search was conducted for eligible studies published before August 2021. The primary endpoint was overall survival (OS). Pooled hazard ratios (HRs) and their 95% confidence intervals (CIs) were calculated for prognostic parameters. Subgroup analyses based on intensive treatment were performed.
Results: Thirty-two studies with 7,062 patients were included. As compared to wild-type carriers, AML patients with TP53 mutations had significantly shorter OS (HR: 2.40, 95% CI: 2.16-2.67, I2: 46.6%). Similar results were found in DFS (HR: 2.87, 95% CI: 1.88-4.38), EFS (HR: 2.56, 95% CI: 1.97-3.31), and RFS (HR: 2.40, 95% CI: 1.79-3.22). Mutant TP53 predicted inferior OS (HR: 2.77, 95% CI: 2.41-3.18) in the intensively treated AML subgroup, compared with the non-intensively treated group (HR: 1.89, 95% CI: 1.58-2.26). Among intensively-treated AML patients, the age of 65 did not affect the prognostic value of TP53 mutations. Besides, TP53 mutation was also strongly associated with an elevated risk of adverse cytogenetics, which conferred a dismal OS in AML patients (HR: 2.03, 95% CI: 1.74-2.37).
Conclusion: TP53 mutation exhibits a promising potential for discriminating AML patients with a worse prognosis, thus being capable of serving as a novel tool for prognostication and therapeutic decision-making in the management of AML.
期刊介绍：
This journal is devoted to all areas of transfusion medicine. These include the quality and security of blood products, therapy with blood components and plasma derivatives, transfusion-related questions in transplantation, stem cell manipulation, therapeutic and diagnostic problems of homeostasis, immuno-hematological investigations, and legal aspects of the production of blood products as well as hemotherapy. Both comprehensive reviews and primary publications that detail the newest work in transfusion medicine and hemotherapy promote the international exchange of knowledge within these disciplines. Consistent with this goal, continuing clinical education is also specifically addressed.
