Outcomes with allogeneic hematopoietic stem cell transplantation in TP53-mutated myelodysplastic syndrome: A systematic review and meta-analysis. Crit Rev Oncol Hematol 2024; 196:104310.

Abstract
We conducted a systematic review and meta-analysis to evaluate outcomes after allogeneic hematopoietic stem cell transplantation (Allo-HSCT) in TP53-mutated myelodysplastic syndromes (MDS). A literature search was performed on PubMed, Cochrane, Embase, and Clinicaltrials.gov. After screening 626 articles, eight studies were included. Data were extracted following the PRISMA guidelines and analyzed using the meta-package by Schwarzer et al. We analyzed 540 patients. The pooled median 3 (1-5) year overall survival was 21% (95% CI 0.08-0.37, I2=91%, n=540). The pooled relapse rate was 58.9% (95% CI 0.38-0.77, I2=93%, n=487) at a median of 1.75 (1-3) years. The pooled 4-year progression- free survival was 34.8% (95% CI 0.15-0.57, I2=72%, n=105). Outcomes of Allo-HSCT for TP53-mutated MDS patients remain poor, with 21% OS at three years; however, Allo-HSCT confers a survival advantage as compared to non-transplant palliative therapies. Our findings suggest the need to explore novel therapeutic agents in prospective clinical trials.

TP53 mutations are associated with increased infections and reduced hematopoietic cell transplantation rates in myelodysplastic syndrome and acute myeloid leukemia. Transplant Cell Ther 2023:S2666-6367(23)01166-1. [PMID: 36906277 DOI: 10.1016/j.jtct.2023.03.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 02/21/2023] [Accepted: 03/06/2023] [Indexed: 03/11/2023]
Abstract
BACKGROUND Although allogeneic hematopoietic cell transplantation (HCT) is the only potentially curative therapy for patients with poor-risk myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML), only a minority of these patients undergo HCT. TP53-mutated (TP53MUT) MDS/AML is particularly high risk, yet fewer TP53MUT patients undergo HCT than other poor-risk TP53-wild type (TP53WT) patients. OBJECTIVE We hypothesized that TP53MUT MDS/AML patients have unique risk factors affecting rates of HCT, and therefore investigated phenotypic changes that may prevent patients with TP53MUT MDS/AML from receiving HCT. STUDY DESIGN This study was a single center retrospective analysis of outcomes for adults with newly diagnosed MDS or AML (n=352). HLA typing was used as a surrogate for physician "intent to transplant." Multivariable logistic regression models were used to estimate odds ratios (OR) for factors associated with HLA typing, HCT, and pre-transplant infections. Multivariable Cox proportional hazards models were used to create predicted survival curves for patients with and without TP53 mutations. RESULTS Overall significantly fewer TP53MUT patients underwent HCT compared to TP53WT patients (19% versus 31%, p=0.028). Development of an infection was significantly associated with decreased odds of HCT (OR=0.42, 95% CI: 0.19-0.90) and worse overall survival (HR=1.46, 95% CI: 1.09-1.96) in multivariable analyses. TP53MUT disease was independently associated with increased odds of developing an infection (OR 2.18, 95% CI: 1.21-3.93), bacterial pneumonia (OR 1.83, 95% CI: 1.00-3.33), and invasive fungal infection (OR 2.64, 95% CI: 1.34-5.22) prior to HCT. Infections were the cause of death in significantly more patients with TP53MUT disease (38% vs 19%, p=0.005). CONCLUSIONS With substantially more infections and decreased HCT rates in patients with TP53 mutations, this raises the possibility that phenotypic changes occurring in TP53MUT disease may affect infection susceptibility in this population and drastically impact clinical outcomes.

Abstract
Simple Summary The importance of gene variants in the prognosis of myelodysplastic syndromes (MDSs) has been repeatedly reported in recent years. Especially, TP53 mutations are independently associated with a higher risk category, resistance to conventional therapies, rapid transformation to leukemia, and a poor outcome. In the review, we discuss the features of monoallelic and biallelic TP53 mutations within MDS, the carcinogenic mechanisms, and the predictive value of TP53 variants in current standard treatments including hypomethylating agents, allogeneic hematopoietic stem cell transplantation, and lenalidomide, as well as the latest progress in TP53-targeted therapy strategies in MDS. Abstract Myelodysplastic syndromes (MDSs) are heterogeneous for their morphology, clinical characteristics, survival of patients, and evolution to acute myeloid leukemia. Different prognostic scoring systems including the International Prognostic Scoring System (IPSS), the Revised IPSS, the WHO Typed Prognostic Scoring System, and the Lower-Risk Prognostic Scoring System have been introduced for categorizing the highly variable clinical outcomes. However, not considered by current MDS prognosis classification systems, gene variants have been identified for their contribution to the clinical heterogeneity of the disease and their impact on the prognosis. Notably, TP53 mutation is independently associated with a higher risk category, resistance to conventional therapies, rapid transformation to leukemia, and a poor outcome. Herein, we discuss the features of monoallelic and biallelic TP53 mutations within MDS, their corresponding carcinogenic mechanisms, their predictive value in current standard treatments including hypomethylating agents, allogeneic hematopoietic stem cell transplantation, and lenalidomide, together with the latest progress in TP53-targeted therapy strategies, especially MDS clinical trial data.

Abstract
TP53 gene mutations are common in myelodysplastic syndromes (MDS). Previous studies have reported their detrimental effects on patient survival. However, current treatment strategies mainly based on hypomethylating agent therapy (HMA) and hematopoietic stem cell transplantation (HSCT) still leave a lot to be desired. And there is also a lack of studies on large sample with a view to the refinement of specific characteristics and disease progression. So we performed a meta-analysis including 20 studies compromising 5067 patients to assess the prognostic impact and clinical characteristics of TP53 mutations in MDS patients. The overall hazard ratio for overall survival (OS) was 2.14 (95% confidence interval 1.94-2.37, P < .00001) compared with patients with MDS without TP53 mutations. Lower progression-free survival and leukemia-free survival were associated with TP53 mutations. Subgroup analysis revealed that TP53 mutations were significantly associated with high levels of blast cells and karyotypic aberrations. And among Asian population, the adverse impact on OS of TP53 mutations seemed worse than those in Western countries. (HR 2.87 vs. 2.02, P = .01). In addition, TP53 mutations had no effect on response to HMA therapy, and HSCT improved OS in patients carrying TP53 mutations.

Abstract
Recent advancements in next-generation sequencing (NGS) technologies allow the simultaneous identification of targeted copy number alterations (CNAs) as well as somatic mutations using the same panel-based NGS data. We investigated whether CNAs detected by the targeted NGS data provided additional clinical implications, over somatic mutations, in myelodysplastic syndrome (MDS). Targeted deep sequencing of 28 well-known MDS-related genes was performed for 266 patients with MDS. Overall, 215 (80.8 %) patients were found to have at least one somatic mutation; 67 (25.2 %) had at least one CNA; 227 (85.3 %) had either a somatic mutation or CNA; and 12 had CNA without somatic mutations. Considering the clinical variables and somatic mutations alone, multivariate analysis demonstrated that sex, revised International Prognostic Scoring System (IPSS-R), and NRAS and TP53 mutations were independent prognostic factors for overall survival. For AML-free survival, these factors were sex, IPSS-R, and mutations in NRAS, DNMT3A, and complex karyotype/TP53 mutations. When we consider clinical variables along with somatic mutations and CNAs, genetic alterations in TET2, LAMB4, U2AF1, and CBL showed additional significant impact on the survivals. In conclusion, our study suggests that the concurrent detection of somatic mutations and targeted CNAs may provide clinically useful information for the prognosis of MDS patients.

Asian Population Is More Prone to Develop High-Risk Myelodysplastic Syndrome, Concordantly with Their Propensity to Exhibit High-Risk Cytogenetic Aberrations. Cancers (Basel) 2021; 13:cancers13030481. [PMID: 33513838 PMCID: PMC7865620 DOI: 10.3390/cancers13030481] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 01/13/2021] [Accepted: 01/19/2021] [Indexed: 12/15/2022] Open
Abstract
Simple Summary The world population is genetically and environmentally diverse. In particular, genetic differences related to an ethnic factor may underlie differences in cancer phenotypic expression. Therefore, we compared the epidemiology, and the clinical, biological and genetic characteristics of myelodysplastic syndrome (MDS) between Asian and Western countries. Our results show substantial differences in the incidence and age of onset between Asian and Western MDS patients. A higher proportion of Asian MDS patients fall into the high- and very-high risk prognostic MDS groups. This finding is supported by the identification of a higher proportion of high-risk cytogenetic aberrations in Asian MDS patients. However, the survival rate is similar for Western and Asian MDS patients. Our findings may impact the clinical management as well as the strategy of clinical trials targeting those genetic aberrations and mutations depending on the world area where they are run. Abstract This study explores the hypothesis that genetic differences related to an ethnic factor may underlie differences in phenotypic expression of myelodysplastic syndrome (MDS). First, to identify clear ethnic differences, we systematically compared the epidemiology, and the clinical, biological and genetic characteristics of MDS between Asian and Western countries over the last 20 years. Asian MDS cases show a 2- to 4-fold lower incidence and a 10-year younger age of onset compared to the Western cases. A higher proportion of Western MDS patients fall into the very low- and low-risk categories while the intermediate, high and very high-risk groups are more represented in Asian MDS patients according to the Revised International Prognostic Scoring System. Next, we investigated whether differences in prognostic risk scores could find their origin in differential cytogenetic profiles. We found that 5q deletion (del(5q)) aberrations and mutations in TET2, SF3B1, SRSF2 and IDH1/2 are more frequently reported in Western MDS patients while trisomy 8, del(20q), U2AF1 and ETV6 mutations are more frequent in Asian MDS patients. Treatment approaches differ between Western and Asian countries owing to the above discrepancies, but the overall survival rate within each prognostic group is similar for Western and Asian MDS patients. Altogether, our study highlights greater risk MDS in Asians supported by their cytogenetic profile.

Abstract
TP53 dysregulation plays a pivotal role in the molecular pathogenesis of myelodysplastic syndromes (MDS), identifying a subgroup of patients with peculiar features. In this review we report the recent biological and clinical findings of TP53-mutated MDS, focusing on the molecular pathways activation and on its impact on the cellular physiology. In MDS, TP53 mutational status is deeply associated with del(5q) syndrome and its dysregulation impacts on cell cycle, DNA repair and apoptosis inducing chromosomal instability and the clonal evolution of disease. TP53 defects influence adversely the MDS clinical outcome and the treatment response rate, thus new therapeutic approaches are being developed for these patients. TP53 allelic state characterization and the mutational burden evaluation can therefore predict prognosis and identify the subgroup of patients eligible for targeted therapy. For these reasons, in the era of precision medicine, the MDS diagnostic workup cannot do without the complete assessment of TP53 mutational profile.

Abstract
Objective: To evaluate the outcomes of myelodysplastic syndromes (MDS) patients who received HLA-matched sibling donor allogeneic peripheral blood stem cell transplantation (MSD-PBSCT) . Methods: The clinical data of 138 MDS patients received MSD-PBSCT from Sep. 2005 to Dec. 2017 were retrospectively analyzed, and the overall survival (OS) rate, disease-free survival (DFS) rate, relapse rate (RR) , non-relapse mortality (NRM) rate and the related risk factors were explored. Results: ①After a median follow-up of 1 050 (range 4 to 4 988) days, the 3-year OS and DFS rates were (66.6±4.1) % and (63.3±4.1) %, respectively. The 3-year cumulative incidence of RR and NRM rates were (13.9±0.1) % and (22.2±0.1) %, respectively. ②Univariate analysis showed that patients with grade Ⅲ-Ⅳ acute graft-versus-host disease (aGVHD) or hematopoietic cell transplantation comorbidity index (HCT-CI) ≥2 points or patients in very high-risk group of the Revised International Prognostic Scoring System (IPSS-R) had significantly decreased OS[ (42.9±13.2) %vs (72.9±4.2) %, χ(2)=8.620, P=0.003; (53.3±7.6) %vs (72.6±4.7) %, χ(2)=6.681, P=0.010; (53.8±6.8) %vs (76.6±6.2) %vs (73.3±7.7) %, χ(2)=6.337, P=0.042]. For MDS patients with excess blasts-2 (MDS-EB2) and acute myeloid leukemia patients derived from MDS (MDS-AML) , pre-transplant chemotherapy or hypomethylating agents (HMA) therapy could not improve the OS rate[ (60.4±7.8) %vs (59.2±9.6) %, χ(2)=0.042, P=0.838]. ③Multivariate analysis indicated that the HCT-CI was an independent risk factor for OS and DFS (P=0.012, HR=2.108, 95%CI 1.174-3.785; P=0.008, HR=2.128, 95%CI 1.219-3.712) . Conclusions: HCT-CI was better than the IPSS-R in predicting the outcomes after transplantation. The occurrence of grade Ⅲ-Ⅳ aGVHD is a poor prognostic factor for OS. For patients of MDS-EB2 and MDS-AML, immediate transplantation was recommended instead of receiving pre-transplant chemotherapy or HMA therapy.
