A. V. Rumyantseva, M. V. Bannikova, T. V. Azizova

Background. Gynecological malignant neoplasms (GMN) are the leading disease group among female cancers.Objective: to characterize GMN in females occupationally exposed to ionizing radiation over prolonged periods.Materials and methods. The cohort considered in the study included females (n = 5689) who had been hired at the Mayak Production Association in the period between 1948 and 1982. All these females were exposed to ionizing radiation over prolonged periods during their employment. They were followed up until 31.12.2018. Two groups of females were identified in the study cohort: the one with a verified GMN (the main group) and another one free of GMN (the control group). The occupational and reproductive characteristics were analyzed for the identified groups of females, and associations of GMN with various risk factors were assessed.Results. Among GMN the uterine corpus cancer had the top position. In 70 % of the females GMN were diagnosed during a menopausal period. The females of the main group demonstrated significantly higher frequency of underlying pre-malignant conditions (endometriosis, uterine myoma, endometrial hyperplastic processes, ovarian epidermoids, menopausal bleedings) compared to the control group.Conclusion. Studies of GMN in females occupationally exposed to ionizing radiation over prolonged periods for sure are of a certain scientific and practical interest. The findings can provide the basis for specialized cancer care for employees of the nuclear industry.
