The prognostic value of circulating myeloblasts in patients with myelodysplastic syndromes

AbstractThe prognostic value of peripheral blasts (PB) is not well-studied in patients with myelodysplastic syndromes (MDS). We evaluated the impact of PB on overall survival (OS) and transformation to acute myeloid leukemia (AML) in a large cohort. The MDS database at the Moffitt Cancer Center was retrospectively reviewed to identify patients with ≥ 1% PB (PB-MDS) and those without PB (BM-MDS). We also assessed the correlation between PB and gene mutations. One thousand seven hundred fifty-eight patients were identified, among whom 13% had PB near the time of diagnosis. PB-MDS patients were more likely to be younger with trilineage cytope nia, complex karyotype, higher-risk disease, transfusion dependence, and therapy-related MDS. The rate of AML transformation was 49 vs. 26% (p

Authors: Nenova I, Grudeva-Popova J Abstract The growing number of successfully cured cancer patients has created a new field in oncogenesis. The life expectancy of such patients has increased, however this favorable event may create enough time for epigenetic events to occur which can cause a new carcinognic event, i.e. a secondary malignancy. The terms in use are second primary malignancies as well as therapy-related neoplasms in case the treatment of the first neoplasm is a direct cause. Second primary malignancies can be hematological neoplasms or solid tumors, with solid tumors having higher frequency. Hematol...

CONCLUSIONSAdjuvant chemotherapy is associated with a small but significant increase in the risk of AML and MDS, especially with regimens that include A. Longer follow‐up is needed to confirm that risk is not increased with the recently adopted TC regimen. Cancer 2017. © 2017 American Cancer Society.

AbstractImmunocompromised patients are at high risk of invasive fungal infections (IFI), in particular those with haematological malignancies undergoing remission-induction chemotherapy for acute myeloid leukaemia (AML) or myelodysplastic syndrome (MDS) and recipients of allogeneic haematopoietic stem cell transplants (HSCT). Despite the development of new treatment options in the past decades, IFI remains a concern due to substantial morbidity and mortality in these patient populations. In addition, the increasing use of new immune modulating drugs in cancer therapy has opened an entirely new spectrum of at risk periods. ...

Conclusion: When considering mutations in only normal karyotype patients, the frequency of FLT3-ITD, NPM1, DNMT3A mutations in CN-AML patients in upper Northern Thailand were found to occur at lower rates than in Western patients and to differ from other Asian populations including parts of Thailand. No mutations were observed in CN-MDS cases. Some types of gene mutations differed from previous studies, possibly attributable to differences in geography, lifestyle and genetic backgrounds. Links with age ≤ 60 years and history of hypertension were found. Investigation of these three genes in an intermediate risk group wit...

Publication date: Available online 9 November 2017 Source:Seminars in Cancer Biology Author(s): Christian Flotho, Sebastian Sommer, Michael Lübbert Myelodysplastic syndrome (MDS) is a clonal bone marrow disorder, typically of older adults, which is characterized by ineffective hematopoiesis, peripheral blood cytopenias and risk of progression to acute myeloid leukemia. Juvenile myelomonocytic leukemia (JMML) is an aggressive myeloproliferative neoplasm occurring in young children. The common denominator of these malignant myeloid disorders is the limited benefit of conventional chemotherapy and a particular responsiv...

Conclusion This study tentatively suggests that the diagnosis of childhood malignancy follows a seasonal trend in Korea, and has a possible correlation with viral prevalence in several diseases. Further long-term analysis of epidemiological data is needed to explore possible causality.

Jones, Kirsten Grønbæk Over the past few years it has become clear that vitamin C, as a provider of reduced iron, is an essential factor for the function of epigenetic regulators that initiate the demethylation of DNA and histones. Vitamin C deficiency is rare in the general population, but is frequently observed in patients with cancer. Genes encoding epigenetic regulators are often mutated in cancer, underscoring their cent...

Abstract Decitabine has been explored as a reduced‐intensity therapy for older or unfit patients with acute myeloid leukemia (AML). To better understand the risk of infections during decitabine treatment, we retrospectively examined the culture results from each infection‐related serious adverse event that occurred among 85 AML and myelodysplastic syndromes (MDS) patients treated in a prospective clinical study using 10‐day cycles of decitabine at Washington University School of Medicine. Culture results were available for 163 infection‐related complications that occurred in 70 patients: 90 (55.2%) events were cult...
