Background and objective: Colorectal cancer (CRC) remains one of the most widespread human malignancies. The aim of this study was to study trends of the incidence of CRC in Kazakhstan. Materials and Method: This retrospective study was done using descriptive and analytical methods of oncoepidemiology. Results: During the study period from 2009 to 2018, 28,950 new cases of CRC were recorded, 13,779 (47.6%) cases were allocated to men and 15,171 (52.4%) to women. It was found that the incidence rate of CRC increased from 14.79 (2009) to 17.72 in 2018 and the overall growth was 2.93 cases per 100,000. This increase was due to the age structure -∑Δ A =+1.42, the risk of acquiring illness -∑Δ R =+1.31, and their combined effect -∑Δ RA =+0.20. The component analysis results revealed that the increase in the number of patients with CRC was mainly due to the growth of the population (ΔP=+37.7%), changes in age structure (Δ A =+26.6%), and changes associated with the risk of acquiring illness (Δ R =+24.6%). The number of patients (both sexes) was increasing in many regions largely due to the influence of the age structure of the population. In addition, it was found that growth in the number of patients in most regions, both men and women, was associated primarily with the risk of acquiring illness. Conclusion: The findings of the current study showed increasing trends in the incidence of CRC in all regions of the country. These changes were mainly influenced by demographic factors (population size and age structure), risk of acquiring the disease, and their combined effect.
Traumatic brain injury (TBI) is one of the most severe and common forms of damage to the central nervous system. At the same time, traumatic subdural hemorrhage refers to severe TBI leading to severe disability and death. Aim of the research. To study the epidemiological features of mortality from traumatic subdural hemorrhage in Kazakhstan. Material and Methods. The study was retrospective, 2009-2018, the material was data on cases of death from traumatic subdural hemorrhage in the country, descriptive and analytical methods of epidemiology were used. Results and discussion. It is established that the average age of those who died from traumatic subdural hemorrhage in men (44.5±0.78 years) was younger than in women patients (47.6±1.17 years). The crude and standardized mortality rates for men (1.33±0.070/0000 and 1.39±0.070/0000, respectively) were higher than for women (0.45±0.040/0000 and 0.42±0.040/0000, respectively). Age indicators had a unimodal increase with a peak of mortality in the group of 70 years and older in both men (2.8±0.38) and women (1.05±0.14). Trends in age-related indicators in men and women tended to increase, with the most pronounced growth rates of the equalized indicators being at the age of 70 years and older in men (Tgr=+7.1%), and in women (Tgr=+9.2%). Conclusions. The analysis of mortality from traumatic subdural hemorrhage indicates a gender difference and an increase in mortality in all the studied population groups. The obtained data are recommended to be used for monitoring and evaluation of diagnostic and therapeutic measures in this pathology. Keywords: traumatic subdural hemorrhage, mortality, Kazakhstan
About 3.15 million new cases of colorectal cancer (CRC) are predicted and it is expected that about 1.62 million human will die from this pathology, according to the forecasts of the International Agency for Research on Cancer in 2040. To this aim, an analysis studying studying the indicators of the oncological service for CRC also makes it possible to evaluate the ongoing anti-cancer measures in East Kazakhstan region. Aim. Evaluate some indicators of the oncological service at CRC in East Kazakhstan region in 2009 to 2018. Materials and methods. The research material was data from the Ministry of Health of the Republic of Kazakhstan – annual form No. 7 and 35 regarding CRC (ICD 10 – C18-21) for 2009-2018 in East Kazakhstan region – incidence, mortality, early diagnosis, neglect, morphological verification. A retrospective study using descriptive and analytical methods of biomedical statistics was used as the main method. Results and discussion. For 2009-2018, 3,661 new cases of CRC were registered in East Kazakhstan region for the first time. The incidence of CRC was 25.30/0000 and in dynamics tended to increase from 21.90/0000 (2009) to 25.70/0000 in 2018, the difference was statistically significant (t=1.99 and p=0.047). The mortality rate from CRC tended to decrease from 15.50/0000 to 14.70/0000 (p=0.591), and the average annual mortality rate from CRC was 15.60/0000. The indicators of early diagnosis (the proportion of patients with stage I-II) improved from 58.8% (2009) to 62.3% in 2018, and, accordingly, the indicators of the proportion of neglected patients significantly decreased with stage III (from 25.5% to 20.8%), while with stage IV (from 15.7% to 16.9%) there is a slight increase. The indicators of morphological verification in CRC improved from 90.5% to 98.6% during the studied years. Conclusion. An improvement in the indicators of morphological verification and early diagnosis of CRC was found. The obtained results are recommended to be used for monitoring anti-cancer measures in the region. Keywords: colorectal cancer, incidence, mortality, early diagnosis, neglect, morphological verification.
Objective:The article studies the geographical features of the incidence of gastric cancer (GC) in Kazakhstan. Methods: The retrospective study was done for the period 2009-2018. Descriptive and analytical methods of oncoepidemiology were used. Crude (CR), age-specific (ASIR), age-standardized (ASR), equalized incidence rates and approximation were calculated. The dynamics of indicators was investigated using component analysis according to methodological recommendations. The method of drawing up a cartogram based on the determination of the standard deviation (σ) from the mean (x) was applied. Results: During the study period, 27,467 new cases of GC were registered. The incidence rate increased from 16.80 (2009) to 15.10 in 2018 and the overall decline was 1.70 per 100,000 population, including due to the age structure -∑Δ A =+1.51, due to the risk of acquiring illness -∑Δ R =−2.91 and their combined effect -∑Δ RA =−0.31. The component analysis revealed that the increase in the number of patients with GC was mainly due to the growth of the population (Δ P =+651.8%), changes in its age structure (Δ A =+433.9%) and changes associated with the risk of acquiring illness (Δ R =−832.1%). The cartograms were allocated according to the following criteria: low -up to 14.8 0 / 0000 , average -from 14.8 to 19.2 0 / 0000 , high -above 19.2 0 / 0000 . The results of the spatial assessment showed the highest levels of GC incidence in following regions: Akmola (22.2 0 / 0000 ), North Kazakhstan (22.3 0 / 0000 ), and Pavlodar (23.2 0 / 0000 ). Conclusion: Thus, as a result of the epidemiological analysis, the role of the influence of demographic factors and the risk of acquiring illness on the formation of the number of patients and the incidence of GC was evaluated, while sex differences and geographical variability were established.
