目的提高对维奈克拉联合阿扎胞苷治疗伴t(6;9)急性髓系白血病(AML)的认识。方法回顾性分析宁夏医科大学总医院2020年7月收治的1例接受维奈克拉联合阿扎胞苷治疗的伴t(6;9)AML患者的临床资料, 并复习相关文献。结果患者以发热、皮下结节为临床表现, 结合骨髓细胞形态学、免疫学、遗传学、分子生物学检查, 诊断为AML-M2a伴t(6;9), 基因检测提示DEK-CAN、TP53、DNMT3A、ASXL1、TET2、FLT3-ITD均阳性。患者对常规化疗无效, 因合并严重肺部感染而接受维奈克拉联合阿扎胞苷治疗获得完全缓解, 患者家属拒绝行异基因造血干胞移植, 错过最佳治疗时机, 原发病复发后最终放弃治疗。结论伴t(6;9)AML治疗难度大, 预后极差, 常规化疗无效时维奈克拉联合阿扎胞苷治疗达完全缓解后, 桥接造血干细胞移植可作为此类患者的最佳治疗选择。 相似文献

Acute myeloid leukemias (AML) with myelodysplasia-related changes (AML-MRC) are defined by the presence of multilineage dysplasia (MLD), and/or myelodysplastic syndrome (MDS)-related cytogenetics, and/or previous MDS. The goal of this study was to identify distinct biological and prognostic subgroups based on mutations of ASXL1, RUNX1, DNMT3A, NPM1, FLT3 and TP53 in 125 AML-MRC patients according to the presence of MLD, cytogenetics and outcome. ASXL1 mutations (n=26, 21%) were associated with a higher proportion of marrow dysgranulopoiesis (mutant vs. wild-type: 75% vs. 55%, p=0.030) and were mostly found in intermediate cytogenetic AML (23/26) in which they predicted inferior 2-year overall survival (OS, mutant vs. wild-type: 14% vs. 37%, p=0.030). TP53 mutations (n=28, 22%) were mostly found in complex karyotype AML (26/28) and predicted poor outcome within unfavorable cytogenetic risk AML (mutant vs. wild-type: 9% vs. 40%, p=0.040). In multivariate analysis, the presence of either ASXL1 or TP53 mutation was the only independent factor associated with shorter OS (HR, 95%CI: 2.53, 1.40-4.60, p=0.002) while MLD, MDS-related cytogenetics and previous MDS history did not influence OS. We conclude that ASXL1 and TP53 mutations identify two molecular subgroups among AML-MRCs, with specific poor prognosis. This could be useful for future diagnostic and prognostic classifications. 相似文献

BackgroundFLAG ± Ida (fludarabine, cytarabine, granulocyte colony-stimulating factor, and idarubicin), is a salvage chemotherapy regimen for relapsed or refractory (R/R) acute myeloid leukemia (AML), with complete remission (CR) rates historically ranging from 52% to 63%. We review the outcomes for patients with R/R AML treated with FLAG ± Ida at the University of California Davis Comprehensive Cancer Center.Patients and MethodsAdult patients (≥ 18 years) with R/R AML who received FLAG or FLAG + Ida from January 1, 2012 to October 31, 2016 were identified via chart review. Outcomes evaluated were CR, CR with incomplete hematologic recovery (CRi), overall response rate, overall survival (OS), relapse-free survival, and adverse events.ResultsForty-two patients were included. The median age was 52 years (range, 23-73 years), and 57% were male. Sixteen (38.1%) patients had relapsed disease, and 26 (61.9%) had refractory disease. Most (n = 35; 83.3%) patients had European LeukemiaNet intermediate-risk AML. Responses were CR in 20 (47.6%) and CRi in 6 (14.3%). The median OS was 10 months (range, 0.8-51 months), and the median relapse-free survival was 12 months (range, 1-51 months) for responders. The median OS for patients who achieved CR was not reached, and the estimated 48-month survival rate was 56%. The median OS after CRi or no response was 3.47 and 2.17 months, respectively. The median OS was not significantly different when censored for stem cell transplant following chemotherapy, nor with use/deferral of idarubicin. The most common adverse effects were pancytopenia and infection.ConclusionPatient outcomes after treatment with FLAG ± Ida for R/R AML remain similar to prior reports, confirming its role as a salvage regimen for these patients. 相似文献

IntroductionVenetoclax is a selective B-cell lymphoma 2 (BCL2) inhibitor, which is approved to treat elderly patients with newly diagnosed acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS) in combination with either low-dose cytarabine (ARA-C) or hypomethylating agents. We aimed to collect and share data among the efficacy and safety of venetoclax both as a monotherapy or in combination with other drugs used to treat high-risk MDS or AML.Materials and MethodsA total of 60 patients with a median age of 67 (30-83) years from 14 different centers were included in the final analysis. Thirty (50%) of the patients were women; 6 (10%) of the 60 patients were diagnosed with high-risk MDS and the remaining were diagnosed with AML.ResultsThe best objective response rate (complete remission [CR], complete remission with incomplete hematological recovery (CRi), morphological leukemia-free state [MLFS], partial response [PR]) was 35% in the entire cohort. Best responses achieved during venetoclax per patient number were as follows: 7 CR, 1 CRi, 8 MLFS, 5 PR, and stable disease. Median overall survival achieved with venetoclax was 5 months in patients who relapsed and not achieved in patients who were initially treated with venetoclax. Nearly all patients (86.7%) had experienced a grade 2 or more hematologic toxicity. Some 36.7% of these patients had received granulocyte colony stimulating factor (GCSF) support. Infection, mainly pneumonia (26.7%), was the leading nonhematologic toxicity, and fatigue, diarrhea, and skin reactions were the others reported.ConclusionOur real-life data support the use of venetoclax in patients with both newly diagnosed and relapsed high-risk MDS and AML. 相似文献

TP53 mutations are found in 5–10% of MDS and AML, where they are generally associated with complex karyotype and an overall poor prognosis. However, the impact of TP53 mutations in MDS treated with azacitidine (AZA) remains unclear. We analyzed TP53 mutations in 62 patients with high risk MDS or AML treated with AZA. A TP53 mutation was found in 23 patients (37.1%), associated with complex karyotype in 18 (78.3%) of them. TP53 mutations had no significant impact on response or complete response to AZA (p = 0.60 and p = 0.26, respectively). By univariate analysis, OS was negatively influenced by the presence of TP53 mutation (median OS 12.4 months versus 23.7 months, p < 10−4), abnormal cytogenetics (median OS 14.4 months vs 33 months, p = 0.02) complex cytogenetics (median OS 12.7 months versus 23.7 months, p = 0.0005), and a diagnosis of AML (median 14.5 months vs 21.2 months for MDS or CMML, p = 0.02). By multivariate analysis, only TP53 mutational status (HR 2.89 (95% confidence interval 1.38–6.04; p = 0.005) retained statistical significance for OS. Results were similar when the analysis was restricted to MDS and CMML patients, excluding AML (HR = 2.46 (95% confidence interval: 1.1–6.4); p = 0.04)). 相似文献
