Abstract

Background: The aim of this study was to estimate the cancer risks and mortalities of different types induced by routine examinations of digital radiography for one year in Mazandaran province, Iran. Materials and Methods: Radiation parameters and calculated entrance skin dose (ESD) values of 13 digital radiographic examinations were collected from 2340 patients at 18 high-patient-load radiography centers. Organ mean doses were estimated based on the collected parameters applying PCXMC software. The BEIR VII-Phase 2 model was used to calculate the induced cancer risks and mortalities of various cancer types at different ages. Results: The average ± standard deviation (SD) lifetime risks (incidence probability in 100,000 people) induced by radiations from radiography examinations for one year was 51.29±4.73 and 99.62±7.36 for new-born males and females, respectively. The lifetime cancer risk decreased with age and reached 3.77±0.62 and 4.88±0.07 for 80-year men and women, respectively. The average lifetime risks of mortality due to cancers induced by annual radiographies were obtained at 14.18±1.62 and 22.83±2.55 for new-born males and females, respectively. This risk reduced with age and was reached 1.97±0.27 and 2.45±0.38 for men and women at the age of 80 years, respectively. Conclusion: Our results showed that there are low but significant risks of cancer incidence for patients undergoing digital radiography, which included a large percentage of the population in Mazandaran province, especially for children and newborns. Therefore, further efforts like appropriate patient setup and beam geometry should be carried out to decrease patient doses.
马赞德兰省不同年龄患者常规数字放射检查诱发癌症风险和死亡率的评估
背景:本研究的目的是评估伊朗马赞德兰省一年来数字化放射常规检查诱发的不同类型癌症风险和死亡率。材料和方法:收集来自18个高患者负荷放射照相中心2340名患者的13次数字放射照相检查的放射参数和计算的入射皮肤剂量(ESD)值。应用PCXMC软件根据收集的参数估计器官平均剂量。BEIR VII-2期模型用于计算不同年龄的各种癌症类型的诱发癌症风险和死亡率。结果:新生儿男性和女性一年内放射检查诱发的平均±标准差(SD)寿命风险(10万人中的发病概率)分别为51.29±4.73和99.62±7.36。癌症的终生风险随着年龄的增长而降低,80岁男性和女性分别达到3.77±0.62和4.88±0.07。新生儿男性和女性因年度射线照片诱发的癌症死亡的平均终生风险分别为14.18±1.62和22.83±2.55。这种风险随着年龄的增长而降低,80岁时男性和女性分别达到1.97±0.27和2.45±0.38。结论:我们的研究结果表明,接受数字化放疗的患者癌症发病率较低,但风险显著,其中包括马赞达兰省的大部分人口,尤其是儿童和新生儿。因此,应进一步努力,如适当的患者设置和波束几何形状,以减少患者剂量。
