Abstract
INTRODUCTION Acute myeloid leukemia (AML) is a hematological malignancy with high mortality rate. The treatment is especially challenging in patients older than 65 years, which is the large majority of those. For patients unfit for intensive chemotherapy regimens, only palliative cytoreduction and basic supportive care used to be the options in our unit. However, from 2018, the azacitidine-venetoclax combination has been a new therapeutic alternative. This treatment resulted in marked survival benefit in clinical trials, however, its impact on the daily clinical practice and the entire patient population is unclear. OBJECTIVE Our goal was to evaluate how the application of azacitidine-venetoclax changed the treatment and survival of AML patients in our practice. METHOD We retrospectively analyzed the available clinical data of all AML patients treated consecutively between January 1, 2011 and December 31, 2021 at the 3rd Department of Internal Medicine (from 2020 onward called Department of Internal Medicine and Hematology), examining their treatment depending on the time period of therapy (2011-2017 and 2018-2021). Patients with acute promyelocytic leukemia were excluded. RESULTS 423 patients were diagnosed during this period. The number of cases showed a marked increase: in the first 7 years of our study, 184 patients were diagnosed, while this rose to 239 during the subsequent 4 years. The median age of patients was 67.6 years, with more than 60% of patients aged over 65. An improving trend can be observed in the overall survival: between 2011 and 2017, the median overall survival was 4.8 ± 0.9 months, while between 2018 and 2021, it was 8.3 ± 1.4 months (p = 0.051). Moreover, in the case of patients over 65 there was a significant overall survival improvement: 3.1 ± 0.5 vs. 4.9 ± 0.6 months (p = 0,01). The main factor behind this improvement could be that a large proportion of over 65 patients previously only fit for supportive care could now be treated with azacitidine-venetoclax: the percentage of actively treated patients grew from 57.1% to 75.3% in the second period. CONCLUSION The survival of patients unfit for curative therapy and older than 65 showed a steady increase which can be attributed to the introduction of new therapeutic alternatives.

DNA Methylation Events as Markers for Diagnosis and Management of Acute Myeloid Leukemia and Myelodysplastic Syndrome. DISEASE MARKERS 2017; 2017:5472893. [PMID: 29038614 PMCID: PMC5606093 DOI: 10.1155/2017/5472893] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/08/2017] [Revised: 07/17/2017] [Accepted: 07/30/2017] [Indexed: 01/18/2023]
Abstract
During the onset and progression of hematological malignancies, many changes occur in cellular epigenome, such as hypo- or hypermethylation of CpG islands in promoter regions. DNA methylation is an epigenetic modification that regulates gene expression and is a key event for tumorigenesis. The continuous search for biomarkers that signal early disease, indicate prognosis, and act as therapeutic targets has led to studies investigating the role of DNA in cancer onset and progression. This review focuses on DNA methylation changes as potential biomarkers for diagnosis, prognosis, response to treatment, and early toxicity in acute myeloid leukemia and myelodysplastic syndrome. Here, we report that distinct changes in DNA methylation may alter gene function and drive malignant cellular transformation during several stages of leukemogenesis. Most of these modifications occur at an early stage of disease and may predict myeloid/lymphoid transformation or response to therapy, which justifies its use as a biomarker for disease onset and progression. Methylation patterns, or its dynamic change during treatment, may also be used as markers for patient stratification, disease prognosis, and response to treatment. Further investigations of methylation modifications as therapeutic biomarkers, which may correlate with therapeutic response and/or predict treatment toxicity, are still warranted.
