Abstract
BACKGROUND The epidemiology of myeloid hematologic malignancies in Italy has been poorly investigated. METHODS We used a validated database of 1974-2003 incident cases of hematologic malignancies among the resident population (all ages) of Sardinia, Italy, to describe the incidence of myeloid malignancies overall (N = 4389 cases) and by subtype. We investigated the time trend of acute myeloid leukemia (N = 1227 cases), chronic myeloid leukemia (N = 613 cases), and myelodysplastic syndrome (N = 1296 cases), and used Bayesian methods to explore their geographic spread, and Poisson regression analysis to estimate their association with environmental and socio-economic factors. RESULTS The annual standardized (world population) incidence rate (IR) of myeloid malignancies over the study period was 6.5 per 100,000 (95% CI 6.2-6.7). Myelodysplastic syndromes were the most prevalent subgroup (IR = 1.7, 95% CI 1.5-1.8). Incidence of all myeloid malignancies combined increased sharply during the study period with an annual percent change (APC) of 10.06% (95% CI 9.51-10.61), 19.77% for myelodysplastic syndromes (95% CI 19.63-19.91), and 3.18% (95% CI 2.99-3.37) for acute myeloid leukemia. Chronic myeloid leukemia did not show an upward trend. Apart from sporadic excesses in small rural communities and the major urban area, there was no evidence of spatial clustering. The risk of myeloid malignancies increased with increasing prevalence of sheep breeding. CONCLUSIONS Our results might prompt further research on the local genetic and environmental determinants of myeloid hematologic malignancies.

Elnaggar MG, Mosad E, Makboul A, Shafik EA. Cytogenetic profile of adult acute myeloid leukemia in Egypt: a single-center experience. Mol Cytogenet 2022; 15:43.

Abstract
Background Acute myeloid leukemia (AML) is a diverse disease characterized by the expansion of blasts of myeloid lineage. Cytogenetic testing is the cornerstone for risk stratification of AML patients. Geographical and environmental factors may play a very important role in the development of leukemia and several differences in genetic profile may be seen among different ethnicities. In our study, we evaluated cytogenetic findings of adult AML patients in South Egypt. Methods Cytogenetic testing (karyotyping and M-FISH) was performed for 120 adult patients with AML. Twenty metaphases were analyzed for each patient. Results In our study, the median age of AML patients was 36.5 years, with an age range between 18 and 86 years. 56.7% of patients had normal karyotypes and 43.3% of patients had clonal cytogenetic abnormalities. t (15;17) was the most detected structural abnormality, and + 8 was the most detected numerical abnormality. Regarding cytogenetic risk stratification, 65% of patients were in the intermediate-risk category. Conclusion The cytogenetic profile of AML patients in our locality showed some differences and some similarities with cytogenetic profiles in different Arab, Asian and Western countries. Further studies are needed using advanced techniques such as next-generation sequencing and optical genome mapping to elucidate more ethnic and geographic genetic heterogeneity among different countries.

Abstract
Acute myeloid leukemia (AML) is the most prevalent acute leukemia in adults and is responsible for the majority of cancer-related mortality. In Saudi Arabia, leukemia is ranked the fifth most prevalent type of malignancy in adults. Our aim is to review existing epidemiologic data in Saudi Arabia and develop consensus guidelines for management of AML.

Abstract
Acute myeloid leukemia (AML) is a malignant disorder of the bone marrow which is characterized by the clonal expansion and differentiation arrest of myeloid progenitor cells. The age-adjusted incidence of AML is 4.3 per 100,000 annually in the United States (US). Incidence increases with age with a median age at diagnosis of 68 years in the US. The etiology of AML is heterogeneous. In some patients, prior exposure to therapeutic, occupational or environmental DNA-damaging agents is implicated, but most cases of AML remain without a clear etiology. AML is the most common form of acute leukemia in adults and has the shortest survival (5-year survival = 24%). Curative therapies, including intensive chemotherapy and allogeneic stem cell transplantation, are generally applicable to a minority of patients who are younger and fit, while most older individuals exhibit poor prognosis and survival. Differences in patient outcomes are influenced by disease characteristics, access to care including active therapies and supportive care, and other factors. After many years without therapeutic advances, several new therapies have been approved and are expected to impact patient outcomes, especially for older patients and those with refractory disease.

Shysh AC, Nguyen LT, Guo M, Vaska M, Naugler C, Rashid-Kolvear F. The incidence of acute myeloid leukemia in Calgary, Alberta, Canada: a retrospective cohort study. BMC Public Health 2017; 18:94. [PMID: 28774275 PMCID: PMC5543578 DOI: 10.1186/s12889-017-4644-6] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2017] [Accepted: 07/27/2017] [Indexed: 11/17/2022] Open
Abstract
Background The incidence rate of acute myeloid leukemia (AML) was determined in the Calgary Metropolitan Area, a major Canadian city. Methods Data from all patients diagnosed with AML between January 1, 2011 and December 31, 2015 were retrieved from a single, centralized cancer cytogenetics laboratory for bone marrow samples, the sole diagnostic facility of its kind in Southern Alberta. Results The calculated incidence rate was 2.79 cases per 100,000 person-years with a median age of 60, slightly lower than previously published data. The age-standardized incidence rate for Canada was 3.46 cases per 100,000 person-years. The higher value is reflective of Calgary’s younger population compared to the rest of Canada. Higher male incidence and greatest incidence occurring at approximately the age of 85 is similar to data from other developed countries. The lower incidence rates and median age of diagnosis, in comparison with that of other high-income nations, may be due to differences in the proportion of aging citizens in the population. Conclusion This is the first published incidence rate of acute myeloid leukemia (AML) in Canada across all age groups.
