The aim of the study was to describe cases of hepatobiliary system disease in the cohort of employees hired at the main plants of FSUE Mayak Production Association (PA Β«MayakΒ») in 1948- 1982, who were exposed to occupational chronic radiationΠ¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ β Ρ

Colorectal cancer is one of the most common malignant neoplasms. Main causes inducing this type of cancer are factors related to the life style and occupational exposures to chemical agents. Some studies demonstrated an association of colorectal cancer incidence and mortality with ionizing radiation. The aim of the present study was to assess the trend in colorectal cancer incidence in a cohort of nuclear workers employed at the Mayak Production Association who had been exposed to ionizing radiation over prolonged periods. The cohort comprised 22,377 workers (25% of females) employed at one of the main plants (reactors, radiochemical and plutonium production plants) of the Mayak Production Association in 1948-1982 who had been externally exposed to gamma rays (cumulative absorbed colon doses were 0β5.85 Gy with the corresponding median dose of 0.16 Gy) and those who had inhaled aerosols containing plutonium particles had been also internally exposed to alpha radiation (cumulative absorbed colon doses were 0β0.18 Gy with the corresponding median dose of 0.0002 Gy). Over the period of 1948β2018, 239 colon cancers and 186 rectum cancers were diagnosed in the study cohort. The incidence of colorectal malignancies among workers of the study cohort was shown to increase with age above 50. Age-standardized incidence rates were higher in males than in females. The time trend analysis of age-standardized rates of colorectal malignancies among workers of the study cohort was performed using a spline regression. The trend of age-standardized rates of colorectal cancer incidence in the Mayak Production Association workers over the analyzed period was nonmonotonic. In general, the average annual percent change of incidence growth for colon cancer was less than 0.1% (for both sexes), while the corresponding estimates for rectum cancer were 1.1% in males and 30.3% in females. To assess the effect of occupational radiation exposure on the incidence of colorectal malignancies, a radiogenic risk analysis that would take into account non-radiation risk factors should be performed.Π Π°ΠΊ ΡΠΎΠ»ΡΡΠΎΠ³ΠΎ ΠΊΠΈΡΠ΅ΡΠ½ΠΈΠΊΠ° Π²Ρ

Incidence risk for malignant neoplasms of the pancreas in a cohort of atomic industry workers
Incidence of malignant neoplasms of the pancreas (PMN) has increased over recent decades. Still the evidence on ionizing radiation impact on pancreas tumorogenesis is inconsistent. The study was aimed to assess the impact of occupational radiation exposure on PMN incidence risk among staff members of an atomic industry enterprise - the Federal State Unitary Enterprise Mayak Production Association (Mayak PA) - taking into account non-radiation factors. The study considered the cohort of workers first employed at one of main Mayak PA facilities in 1948-1982 (with the follow-up period until 31 December 2013). Occupational radiation dose estimates were provided by Mayak Worker Dosimetry System 2008 (external gamma-doses) and Mayak Worker Dosimetry System 2013 (internal alpha-doses from incorporated plutonium). Findings of the study revealed a significant increase of the excess relative risk (ERR) of PMC incidence with increasing doses from internal alpha-particles: ERR/Gy=1.19 (95% confidence interval: 0.36 β 2.56). No association of prolonged total gamma-radiation exposure with PMN incidence risk was found. Similarly to the background population, the PMN incidence risk in the study cohort was dependent on sex and age of the workers as well as on smoking status and index.Π ΠΏΠΎΡΠ»Π΅Π΄Π½ΠΈΠ΅ Π΄Π΅ΡΡΡΠΈΠ»Π΅ΡΠΈΡ Π½Π°Π±Π»ΡΠ΄Π°Π΅ΡΡΡ ΡΠΎΡΡ Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π΅ΠΌΠΎΡΡΠΈ Π·Π»ΠΎΠΊΠ°ΡΠ΅ΡΡΠ²Π΅Π½Π½ΡΠΌΠΈ Π½ΠΎΠ²ΠΎΠΎΠ±ΡΠ°Π·ΠΎΠ²Π°Π½ΠΈΡΠΌΠΈ (ΠΠΠ) ΠΏΠΎΠ΄ΠΆΠ΅Π»ΡΠ΄ΠΎΡΠ½ΠΎΠΉ ΠΆΠ΅Π»Π΅Π·Ρ (ΠΠ).

Colorectal cancer is one of the most common malignant neoplasms. Main causes inducing this type of cancer are factors related to the life style and occupational exposures to chemical agents. Some studies demonstrated an association of colorectal cancer incidence and mortality with ionizing radiation. The aim of the present study was to assess the trend in colorectal cancer incidence in a cohort of nuclear workers employed at the Mayak Production Association who had been exposed to ionizing radiation over prolonged periods. The cohort comprised 22,377 workers (25% of females) employed at one of the main plants (reactors, radiochemical and plutonium production plants) of the Mayak Production Association in 1948-1982 who had been externally exposed to gamma rays (cumulative absorbed colon doses were 0β5.85 Gy with the corresponding median dose of 0.16 Gy) and those who had inhaled aerosols containing plutonium particles had been also internally exposed to alpha radiation (cumulative absorbed colon doses were 0β0.18 Gy with the corresponding median dose of 0.0002 Gy). Over the period of 1948β2018, 239 colon cancers and 186 rectum cancers were diagnosed in the study cohort. The incidence of colorectal malignancies among workers of the study cohort was shown to increase with age above 50. Age-standardized incidence rates were higher in males than in females. The time trend analysis of age-standardized rates of colorectal malignancies among workers of the study cohort was performed using a spline regression. The trend of age-standardized rates of colorectal cancer incidence in the Mayak Production Association workers over the analyzed period was nonmonotonic. In general, the average annual percent change of incidence growth for colon cancer was less than 0.1% (for both sexes), while the corresponding estimates for rectum cancer were 1.1% in males and 30.3% in females. To assess the effect of occupational radiation exposure on the incidence of colorectal malignancies, a radiogenic risk analysis that would take into account non-radiation risk factors should be performed
