ABSTRACT

To investigate the late effects of radiation on child-bearing women, a follow-up study was performed on a 39-year-old survivor 16 years after a (60)Co radiation accident. The woman, Fang, was 19 weeks pregnant at the time of exposure. Physical examinations, a full range of clinical laboratory and imaging tests, as well as cytogenetic analyses were conducted to evaluate Fang's current health conditions. Fang shows the appearance of premature ageing and has a decreased menstrual period. Laboratory studies and imaging tests suggest nodular goitre disease and osteoporosis. Otherwise, no apparent abnormalities were found in the major organs. No malignant tumours were detected by either tumour markers or imaging tests. However, the existence of chromosome aberrations warrants long-term follow-up for tumour incidence in the future. Fang became pregnant 8 years after the accident, but suffered a miscarriage due to the death of the foetus at 6 months into the pregnancy. In conclusion, our findings suggest that the intrauterine death of the foetus might be associated with the previous exposure. There is no evidence of malignant tumours as of the date of the follow-up study. Non-cancerous diseases, i.e. thyroid disease and osteoporosis, which may be related to radiation exposure, are the major manifestations of the long-term effects of the accident.
