Abstract: The paper provides analysis of information about incidence and mortality with respect to malignant neoplasms of the digestive system in the Chernobyl liquidators accumulated in the Russian National Medical and Dosimetric Registry (RNMDR) in the period from 1986 to the beginning of 1998. The study includes male liquidators registered in six regional centers of the RNMDR providing most reliable medical and dosimetric data on an annual basis, namely Northwest, Volgo-Vyatsky, Central-Chernozemny, Povolzhsky, North-Caucasian and Urals. The number of liquidators under study is 96026 persons, which accounts for 57% of all liquidators registered in the RNMDR. The mean dose in the study cohort is 108 mGy, the mean age at the time of entry in the zone is 34.3 years and the total accumulated number of person-years is 1011727. The incidence and mortality rates for cancers of the digestive system were compared for liquidators and the population of Russia in general through calculation of the standardized incidence ratio (SIR) and the standardized mortality ratio (SMR). The values of SIR and SMR with 95% confidence intervals (CI) for malignant neoplasms of the digestive system were estimated to be 0.88 (0.80; 0.97) and 0.72 (0.64; 0.80), respectively. For liquidators who arrived in the zone in 1986 these are 0.97 (0.85; 1.11) and 0.81 (0.70; 0.94), respectively. During the period of 1991-1997, when SIR in liquidators became stable, the values of SIR and SMR with 95% CI for malignant neoplasms of the digestive system were 1.00 (0.90; 1.10) and 0.87 (0.78; 0.98), respectively. For liquidators who arrived in the zone in 1986 these values were 1.15 (1.00; 1.33) and 1.02 (0.86; 1.19), respectively. Estimation of radiation risks for this class of diseases did not reveal any statistically significant increase in cancer incidence or mortality with increase in external radiation dose in liquidators.

Gender problems of oncology in Belarus

Title: Gender problems of oncology in Belarus

Keywords: cancer, oncologic morbidity, mortality, lethality.

Abstract: The data of Belarusian cancer register on the morbidity of malignant tumors were summarized. There was shown the frequency of polyneoplasias. There was given a statistical and analytical picture of male and female oncology in Belarus; there is a tendency of age-specific cancer morbidity in men and women during 1999–2003 and 2006–2010. In Belarus the increase of morbidity takes place due to high cancer morbidity in the older age group and due to aging of population. Over the past 10 years there was observed the decrease of mortality in patients with cancer and the increase of contingents. It is possible to speak about oncomorphosis over the past decades. The highest morbidity is observed in the Gomel and Mogilev regions.

Abstract: This study examined cancer incidence (1986-2008) and mortality (1986-2011) among the Estonian Chernobyl cleanup workers in comparison with the Estonian male population. The cohort of 4810 men was followed through nationwide population, mortality and cancer registries. Cancer and death risks were measured by standardised incidence ratio (SIR) and standardised mortality ratio (SMR), respectively. Poisson regression was used to analyse the effects of year of arrival, duration of stay and time since return on cancer and death risks. The SIR for all cancers was 1.06 with 95% confidence interval 0.93-1.20 (232 cases). Elevated risks were found for cancers of the pharynx, the oesophagus and the joint category of alcohol-related sites. No clear evidence of an increased risk of thyroid cancer, leukaemia or radiation-related cancer sites combined was apparent. The SMR for all causes of death was 1.02 with 95% confidence interval 0.96-1.08 (1018 deaths). Excess mortality was observed for mouth and pharynx cancer, alcohol-related cancer sites together and suicide. Duration of stay rather than year of arrival was associated with increased mortality. Twenty-six years of follow-up of this cohort indicates no definite health effects attributable to radiation, but the elevated suicide risk has persisted.

Abstract: As a result of the Chernobyl disaster, the population of Belarus has been, and continues to be, exposed to more complicated environmental factors than simply those related to radiation exposure. The Chernobyl catastrophe produced barely evaluated consequences both for the population and for the economy of Belarus. We present a brief outline of the radiological problems and population health research in Belarus on the basis of the National and Statistics Reports of Health Care Trends in Belarus (1993–2001) of the Ministry of Health Care of Belarus and its affiliated institutions.
