Aim. To assess the age-related cancer incidence in Omsk and Orenburg Regions.Materials and Methods. We analysed the statistical reports (form 7) obtained from the health authorities of Omsk and Orenburg Regions from 2010 to 2019.Results. Age-specific indicators of cancer incidence in the indicated regions differed significantly (р < 0.001). In the Omsk Region, cancer incidence showed a 65-fold increase with age (from 20 to 79 years), reaching the maximum values at the age of 75-79 years and then decreasing in subjects > 80 years of age (p < 0.05). In the Orenburg region, age-related incidence rates increased 95-fold from 20 to 79 years, reaching a maximum level in the age group of 70-79 years, that was also followed by a decrease in the population over 80 years of age (p < 0.05). Trends in cancer incidence in Omsk and Orenburg Regions were similar to those in Russia, yet the rate was 1.4-1.8-fold lower. Cancer incidence in both regions had a moderate upward trend (increment of 1.2% and 1.5%, respectively; p < 0.001). The highest increase in cancer incidence was detected in subjects between 30 and 39 years and over 80 years of age (Omsk and Orenburg Regions, increment of 1.4% and 2.5%; 1.3% and 1.3%, respectively; p < 0.001).Conclusions. Cancer incidence in the Orenburg Region significantly exceeds that in the Omsk region, yet both of the regions are characterised by the specific trends. We found the most significant increase in cancer incidence in subjects > 80 years of age over the last decade, which was more pronounced in the Omsk Region in comparison with the Orenburg Region.

Aim. To assess the incidence of malignancies in Omsk and Orenburg Regions.Materials and Methods. We analyzed statistical reports (form # 7) from health authorities of Omsk and Orenburg Regions which contain the data on cancer incidence in the population during the last decade (2009-2018).Results. The incidence of malignancies in Omsk and Orenburg Regions had a moderate upward trend. Cancer incidence in the urban population of Orenburg region was higher than in the corresponding rural population, with the opposite ratio in the Omsk region. Average long-term standardized incidence rate of malignancies in Omsk and Orenburg regions was 276,5 0/0000 and 273,0 0/0000, respectively. Cancer incidence prevailed among the male population regardless of the indicator type. The prevalence of males across all patients was 46.0% and 46.8% in Omsk and Orenburg Region, respectively.Conclusion. Average long-term indicators of cancer incidence in Orenburg and Omsk Regions do not differ; however, different incidence pattern was detected in urban and rural populations in these regions over the decade.

Thyroid Cancer Incidence

Thyroid cancer (TC) is the most wide spread malignant tumor of the endocrine glands. According to the International Agency for Research on Cancer, more than 586,200 new cases of TC were registered in the world in 2020. However spatial arrangement of this disease indicates a different distribution of this pathology all over the world. The aim to assess the peculiarities of the incidence of TC in Kazakhstan. Materials and methods. The study was retrospective – the study period was 10 years (2009-2018). The material for the study was data of new cases of TC. In the research were used descriptive and analytical methods of oncoepidemiology. Results and discussion. We found out that the average age of patients with TC in women (51.8±0.2 years) were less than in men (53.2±0.5 years). The crude rate and standardized incidence rates in women (5.4±0.40/0000 and 5.1±0.370/0000, respectively) were higher than in men (0.9±0.10/0000 and 1.1±0.10/0000, respectively). Age-related indicators of the incidence of TC were characterized by a peak in 60-69 years – 4.21±0.200/0000 in men and 15.37±1.210/0000 in women. Trends in morbidity tended to increase in both women (Tg=+7.8%) and men (Tg=+5.0%). Conclusion: Age and gender features of TC incidence were established in the whole country. The obtained data are recommended for use in planning anti-cancer activities. Key words: thyroid cancer, incidence, Kazakhstan.

Background. Prevalence of excess body weight and obesity among children and adolescents has been gradually and significantly increasing over the last decades. The obesity detection rate is markedly affected by both low awareness of primary care physicians and the attitude of parents who pay no attention to the child’s excess weight for a long time considering it the manifestation of excellent health and normal development.Objective. The study aimed at comparative evaluation of the prevalence of obesity among children in the Sverdlovsk region.Methods. A comparative analysis of the prevalence of obesity was carried out, based on official statistical information and results of prophylactic medical examinations over the 2005–2019 period. The gender- and age-related particulars of pathologic obesity among children have been analyzed across the following age groups: 0–4, 5–9, 10–14 and 15–17 years.Results. Based on the incidence of office visits, a two-fold increase of morbid obesity was found in children 0–14 years of age (from 8.3‰ in 2005 to 16.3‰ in 2019 ), and a three-fold increase in adolescents 15–17 years of age (from 11.8‰ to 35.5‰, respectively; р < 0.001). The obesity rate registered during prophylactic medical examinations is two-fold higher than that during the office visits. Over 50% of obesity cases fall on the 10–14 age group, whereas the maximum rates of increase were found in children 5–9 years of age. In the age group of 15–17 years obesity is registered more often in boys than in girls.Conclusion. Significant differences in obesity prevalence rates, according to the office visits and prophylactic medical examinations’ data, attest to delayed diagnosis of excess body weight and insufficient effectiveness of pediatricians dealing with obese children at the stage of pediatric primary care. Cons idering the age-related particulars of obesity prevalence, health professionals working in educational institutions should play a leading role in the diagnosis of excess body weight and provision the follow-up care for children who are at risk for obesity.

Purpose To study the population-based annual incidence rates of exudative, dry and all cases of symptomatic age-related macular degeneration (AMD) in different age and sex groups. Methods. This is a one year, prospective, population-based study on all consecutive new patients with AMD in the hospital district of Central Finland. The diagnosis was confirmed in all patients with slit lamp biomicroscopy, optical coherence tomography (OCT) using a Spectralis HRA + OCT device, and the Heidelberg Eye Explorer 1.6.2.0 program. Fluorescein angiograms were taken when needed. Results. The population-based annual incidence rates of all cases of symptomatic AMD increased from 0.03% (95% CI, 0.01-0.05%) in the age group 50-59 years to 0.82% (95% CI, 0.55-1.09%) in the age group 85-89 years and were 0.2% (95% CI, 0.17-0.24%) in exudative, 0.11% (95% CI, 0.09-0.14%) in dry, and 0.32% (95% CI, 0.28-0.36%) in all cases of AMD in the age group 60 years and older. During the next 20 years in Central Finland the population-based annual incidence rates can be estimated to increase to 0.27% (95% CI, 0.24-0.30%) in exudative, to 0.13% (95% CI, 0.11-0.15%) in dry, and to 0.41% (95% CI, 0.37-0.45%) in all cases of AMD in the age group 60 years and older. The population-based annual incidence of AMD did not show statistically significant differences between males and females (p>0.1). Conclusion: The population-based age-group specific annual incidence rates of symptomatic AMD of this study may help to plan health care provision for patients of AMD.

Background: Liver cancer is the second most common cause of death from cancer worldwide1. In 2013, 79,2000 new cases of liver cancer and 818,000 deaths occurred globally2,3. Chronic infection with HBV accounts for at least 50% of liver cancer globally4. In the United States (US), liver cancer constitute the ninth leading cause of cancer death. The incidence of the cancer has persistently increased in the recent decades. Universal HBV vaccination was introduced in 1992 in the US. However, incidence trends of liver cancer among US children is poorly researched or relevant studies are not up-to-date5. Aim: This study aims to explore the effect of HBV population-wide vaccination program in reducing liver cancer incidence in the vaccinated children and adolescents in the US. Methods: Liver cancer incidence data were obtained from Cancer Incidence in Five Continents (CI5) databases (volumes I to X) from International Agency for Cancer Research (IARC). Data acquisition and analysis covered available incidence data between 1978-2007 from 9 cancer registries from Surveillance, Epidemiology, and End Results Program (SEER) from the US presented in the CI5 databases. Age-specific incidence rates of liver cancer (based on 5 year age groups ie 5-9 year, 10-14 year and 15-19 years) were calculated using age and sex-disaggregated incidence and population data from the SEER cancer registries. Stata software version 14.0 (StataCorp, USA) was used to calculate age-specific incidence rates, using number of liver cancer incident cases in each age group by the number of population in the respective age group. Age-specific rates were analyzed by period of diagnosis and by birth year. Rate ratios were estimated from age-group-specific Poisson regressions. Results: A total of 140 liver cancer incident cases were registered in the 9 SEER registries between 1978 to 2007 in the US. The incidence rate of liver cancer in children 5 to 9 years of age from 1978-1982 was 0.10 per 100,000 children. The incidence increased to 0.16 for the period from 2003-2007. The same trend is seen for the age group 10-14 and 15-19 years of age. Overall, age-specific incidence rates for liver cancer increased across age groups of 5-9, 10-14 and 15-19 year in the population covered by the 9 SEER registries in the US. However, risk estimates (incidence rate ratios, resulted from age-group-specific Poisson regressions did not show statistical significant effects. Conclusion: While the global response to implement population-wide HBV vaccination program is out of question, efforts to establish processes to evaluate the effect of such programs seems to be incomparably limited. Estimating the effect of HBV vaccination will relatively improve with time as further incidence data become available eg upon publication of data from new volume of CI5 databases.

Abstract Background: Globally cervical cancer incidence rate has been declining continuously. However, an unfavorable trend has been observed in China during the past decades, and the underlying reasons remain unclear. We hereby explore the recent trends of cervical cancer incidence, as well as the underlying determinants using data from Guangzhou, one of biggest cities in China. Methods：City-wide cancer registration data were obtained from the Guangzhou Center for Disease Prevention and Control from 2004 to 2018. We used the Joinpoint regression models to estimate the average annual percentage change (AAPC) of age-standardized and age-specific incidence rates by regions and by histological subtype. Age-period-cohort models were applied to analyze the period and birth cohort effects on the time trends. Results: The age-standardized rates (ASRs) of cervical cancer incidence increased at an annual rate of 2.1% [95% confidence interval (CI): 1.0%-3.2%] during 2004-2018. The largest increase in ASRs was found for rural regions, with AAPC of 6.6% [95% CI: 3.7%-9.5%], followed by the suburbs (2.2% [95% CI: 1.0%-3.4%]), while there was no statistically significant increase in urban regions. The ASRs of adenocarcinoma increased faster than those of the squamous cell carcinoma (AAPC=6.53% [95% CI: 5.0%-8.1%] versus 1.79% [95% CI: 0.8%-2.8%]). A downward trend in urban regions was found in the 20-49 age group, whereas an upward trend was found in the 50+ age group, especially in rural regions. An inverted V-shape was found for cohort effects, with the peak varied by regions, i.e., peaked in the 1966 and 1971 birth cohort in the urban and suburb regions, respectively. Period effects kept increasing during the study period. Conclusions: We systematically examine the disparities in the increases of cervical cancer incidence rates using city-wide data from Guangzhou. Extensive efforts are warranted to address the large urban-rural disparities in cervical cancer prevention. The combined strategies of vaccination, screening, and health education should be reinforced and locally customized.
