Turkey is among the countries affected by ionizing radiation from the Chernobyl accident of April 26, 1986. The northern part of Turkey, where the city of Bursa is located, is presumed to be more influenced by the nuclear catastrophe. The radioactive elements in the atmosphere have been examined at various intervals after May 1, 1986 and barium-140 and lanthanum-140, fission agents of uranium-235, have been found in the atmosphere. Their exact concentration could not be measured. The aim of this report is to review the pediatric malignancies diagnosed in our institution between 1986 and 1995, with a view on any significant increase in the number of these cases. The patients were divided into three groups: acute leukemia patients (101 cases), lymphomas (44 cases), and solid tumors (31 cases). All three groups showed a tendency to increase after 1986; the increase in leukemia cases between 1986 and 1995 was found to be significantly higher (p < 0.001) when compared with the years before 1986. The increase in lymphoma and solid tumor cases after 1986 was not found to be significant (p > 0.05). We cannot rule out environmental causes other than the effects of the Chernobyl accident, and we feel that more intense epidemiological studies should be carried out on this subject in other areas of Turkey.
土耳其是受1986年4月26日切尔诺贝利事故电离辐射影响的国家之一。土耳其北部的布尔萨市所在地区，据推测受这场核灾难的影响更大。1986年5月1日之后，人们定期对大气中的放射性元素进行检测，在大气中发现了钡 - 140和镧 - 140，它们是铀 - 235的裂变产物。但无法测量它们的确切浓度。本报告的目的是回顾1986年至1995年间在我们机构诊断出的儿科恶性肿瘤病例，以观察这些病例数量是否有显著增加。患者被分为三组：急性白血病患者（101例）、淋巴瘤患者（44例）和实体瘤患者（31例）。所有三组病例数在1986年之后都有增加的趋势；与1986年之前的年份相比，1986年至1995年间白血病病例的增加显著更高（p < 0.001）。1986年之后淋巴瘤和实体瘤病例的增加不显著（p > 0.05）。我们不能排除切尔诺贝利事故影响之外的环境因素，并且我们认为应该在土耳其其他地区针对这个主题开展更深入的流行病学研究。
