Purpose. To assess the possibility of establishing a relationship between oncologic pathology and the exposure to ionizing radiation from computed tomography (CT) in childhood and adolescence. Materials and methods. The study was carried out retrospectively using cohort methodology; the source of the information was the Register of CT of Ozyorsk. Results. Over a 10-year of follow-up, 890 children living in Ozyorsk has been exposed to ionizing radiation from computed tomography at average dose of 1.7 mSv as a result of examination of the brain (81.5%), thorax and abdomen. 12 cases (1.3%) of malignant neoplasm were revealed. The average age of the examined was 10 years; the period from the moment of exposure to the end of follow-up was about 5 years. There were 9 deaths in the cohort, 4 of them from cancer. In all 4 cases diagnosis of cancer was already supposed before CT scans were performed. Conclusion. Although the result does not allow to draw a conclusion about radiation-induced excess mortality, further follow-up of the cohort is necessary, taking into account the long latency period of malignant neoplasms, as well as the already existing cases of oncological pathology. |
