Leukemia is not only caused by an underlying genetic disease, but a number of environmental variables also contribute to its occurrence. The aim of the current study was to determine the incidence rate of various types of leukemia in children admitted to Bandar Abbas Hospital between 2011 and 2017. </span><br> <span style="line-height:14.0pt"><b><span style="color:#24a3a0">Methods:</span></b> All children referred to Bandar Abbas Children&#39;s Hospital between 2011 and 2017 who were diagnosed with leukemia were included in this retrospective cross-sectional study. The files in the archive department of the hospital and the information provided by the attending physician were the two sources of information needed for this study. Data such as age, gender, type of leukemia and place of residence were collected from the patient records. SPSS-22 was used to analyze the data. </span><br> <span style="line-height:14.0pt"><b><span style="color:#24a3a0">Findings:</span></b> Of 89 patients diagnosed with acute leukemia between 2011 and 2017, 83(93.3%) were diagnosed with acute lymphoblastic leukemia (ALL). B-cell ALL was the most common form of leukemia (69.7%). Boys developed leukemia more frequently than girls (61(68.5%) and 28(31.5%) cases respectively). Most patients with leukemia (70.8%) were aged 1-10 years.</span><br> <b><span style="line-height:107%"><span style="color:#24a3a0">Conclusion:</span></span></b><span style="line-height:107%"> According to the results, ALL was the most common type of leukemia in Hormozgan Province. In addition, the prevalence of leukemia was higher in boys than girls in this province. It is recommended that the risk factors affecting the different types of leukemia in this province be investigated in future studies. </span></span></span><br> <span style="font-size:14px;"><span style="font-family:Times New Roman;"><span style="line-height:normal"><span style="font-family:"Times New Roman","serif""></span></span></span></span></div> Child, Hormozgan, Incidence, Leukemia 0 0 http://caspianjp.ir/browse.php?a_code=A-10-284-1&slc_lang=en&sid=1 Mohammad Ali Molavi shayanmolavi@yahoo.com 10031947532846004880 10031947532846004880 No Department of Pediatric Hematology-Oncology, School of Medicine, Hormozgan University of Medical Sciences, Bandar Abbas, Iran Samaneh Tahmasebi Ghorabi samaneh.tahmasebi70@gmail.com 10031947532846004881 10031947532846004881 No USERN Office, Lorestan University of Medical Sciences, Khorramabad, Iran Fazl Saleh fazlsaleh@yahoo.com 10031947532846004882 10031947532846004882 No Department of Pediatric Hematology-Oncology, School of Medicine, Hormozgan University of Medical Sciences, Bandar Abbas, Iran Abdolmajid Nazemi Qeshmi Dr_amnazemi@yahoo.com 10031947532846004883 10031947532846004883 No Department of Pediatrics, School of Medicine, Hormozgan University of Medical Sciences, Bandar Abbas, Iran Seyede Saba Mazloumi Saba_mazloomi@yahoo.com 10031947532846004884 0009-0006-7784-6946 No Department of Pediatrics, School of Medicine, Hormozgan University of Medical Sciences, Bandar Abbas, Iran Masoumeh Mahmoudi M.mahmudi6934@yahoo.com 10031947532846004885 10031947532846004885 No Children's Hospital Research Center, Hormozgan University of Medical Sciences, Bandar Abbas, Iran Arian Karimi Rouzbahani ariankarimi1998@gmail.com 10031947532846004886 10031947532846004886 Yes Student Research Committee, Lorestan University of Medical Sciences, Khorramabad, Iran
