Introduction: Kidney cancer was considered as the ninth common cancer worldwide. Its incidence and mortality has been increasing for decades. However, in recent years in many countries, there is a downward trend. Objectives: This study sought to evaluate the incidence and mortality rates of renal cancers in Iran compared to its proportion throughout the world. Materials and Methods: All mortality and incidence rates of all countries were extracted from the Global Cancer Project (GLOBOCAN) (data of 2012). The methods of estimation were quality of the estimation and country-specific that was dependent on the quality and on the amount of the available data of each country. Results: The rates have been shown in eight categories; world, very high human development, high human development, medium human development, low human development, less developed, more developed regions in addition to Iran. The rates of Iran were close to medium human developed region rates. In Iran, 1641 kidney cancers cases have been registered which 981 men and 660 women were reported with an overall incidence rate of 1.9 per 100 000 which is less than world incidence rate for kidney cancers. In Iran, the highest incidence was also among patients with age of 75 years and more. Additionally, the lowest incidence rates were among age groups of less than 15 years and age group of 45- 49 years. Conclusion: Considering the lower incidence and mortality rates of kidney cancer in Iran compared to other regions of the world, conducting more studies to find related-risk factors to decline the incidence rates of disease would be necessary.

Background: The present study aims to assess the incidence and mortality rates of gynecological cancers and their changes from 1990 to 2016 at national and subnational levels in Iran. Methods: Annual estimates of incidence and mortality for gynecological cancers from 1990 to 2016 at national and subnational levels were generated as part of a larger project entitled National and Subnational Burden of Diseases, Injuries, and Risk Factors (NASBOD). After the precise processing of data extracted from the Iran Cancer Registry, annual age-standardized incidence and mortality rates were calculated for each cancer, province, year and age group during the period of the study. Results: In 2016, gynecological cancers constituted 8.0% of new cancer cases among women of all ages compared to 3.7% of new cases of cancer among women in 1990. The incidence rate of gynecological cancers has increased from 2.5 (0.9-5.6) per 100000 women in 1990 to 12.3 (9.3–15.7) per 100000 women in 2016, and the most common gynecological cancer has changed from cervical cancer in 1990 to corpus uteri cancer in 2016. Age-standardized incidence rates of ovarian, corpus uteri and vulvovaginal cancers increased from 1.3 (0.5–2.4), 1.7 (0.6–3.0), and 0.3 (0.0–0.7) in 1990 to 4.4 (3.6–5.2), 9.9 (6.8–13.4), and 0.6 (0.2–1.0) in 2016, respectively, showing a 3.3, 5.8 and 1.7-fold increase during this period. Age-standardized incidence rate of cervical cancer was 2.4 (1.7–3.3) cases per 100000 women in 2016 and did not differ significantly from the beginning of the study. An overall reduction was seen in national mortality to incidence ratios (MIR) from 2000 to 2015. Conclusion: The incidence rates of all gynecological cancers in different provinces have shown a converging trend that could indicate that attempts toward health equality have been effective. The declining trend of MIR could be interpreted as advancements in detection of cancer in its early stages and also improvements in treatments, in turn reflecting improvements in access to and quality of care.

SUMMARYDiarrhoea is a leading cause of morbidity and mortality yet diarrhoea specific incidence and mortality rates for older children, adolescents, and adults have not been systematically calculated for many countries. We conducted a systematic literature review to generate regional incidence rates by age and to summarize diarrhoea specific mortality rates for regions of the world with inadequate vital registration data. Diarrhoea morbidity rates range from 29·9 episodes/100 person-years for adults in the South East Asian region to 88·4 episodes/100 person-years in older children in the Eastern Mediterranean region and have remained unchanged in the last 30 years. Diarrhoea mortality rates decline as the child ages and remain relatively constant during adulthood. These data are critical for improving estimates worldwide and further highlight the need for improved diarrhoea specific morbidity and mortality data in these age groups.

Introduction: This is a timely update of incidence and mortality for renal cell carcinoma (RCC) in the United States.Methods: Relying on the Surveillance, Epidemiology, and End Results (SEER) database, we computed age-adjusted incidence, mortality rates and 5-year cancer-specific survival (CSS) for patients with histologically confirmed kidney cancer between 1975 and 2009. Long-term (1975–2009) and short-term (2000–2009) trends were examined by joinpoint analysis, and quantified using the annual percent change (APC). The reported findings were stratified according to disease stage.Results: Age-adjusted incidence rates of RCC increased by +2.76%/year between 1975 and 2009 (from 6.5 to 17.1/100 000 person years, p < 0.001), and by +2.85%/year between 2000 and 2009 (p < 0.001). For the same time points, the corresponding APC for the incidence of localized stage were +4.55%/year (from 3.0 to 12.2/100 000 person years, p < 0.001), and +4.42%/year (p < 0.001), respectively. The incidence rates of regional stage increased by +0.88%/year between 1975 and 2009 (p < 0.001), but stabilized in recent years (2000–2009: +0.56%/year, p = 0.4). Incidence rates of distant stage remained unchanged in long- and short-term trends. Overall mortality rates increased by +1.72%/year between 1975 and 2009 (from 1.2 to 5.0/100 000 person-years, P<0.001), but stabilized between 1994 and 2004 (p = 0.1). Short-term mortality rates increased in a significant fashion by +3.14%/year only for localized stage (p < 0.001).Interpretation: In contemporary years, there is a persisting upward trend in incidence and mortality of localized RCC.

Background and aims. Kidney cancer is among the cancers that have the highest growth rate in all age and racial groups in the world and is as the most deadly type of urinary tract cancer. Since awareness about this cancer incidence status and mortality is essential for better planning, this study aimed to investigate the incidence and mortality rate of kidney cancer and its relationship with the development index in the world in 2012.Method. This study was an ecological study conducted based on GLOBOCAN project of the World Health Organization (WHO) for the countries in the world. The correlation between Standardized Incidence Rates (SIRs) and Standardized Mortality Rates (SMRs) of kidney cancer with HDI and its components was assessed using SPSS18.Results. In total, 337,860 incidence cases (213,924 were men and 123,936 women) and 143,406 deaths (90,802 cases in men and 52,604 in women) of kidney cancer were recorded in 2012. A positive correlation of 0.731 was seen between SIR of kidney cancer and HDI (p≤0.001). Also, a negative correlation of 0.627was seen between SMR of kidney cancer and HDI (p≤0.001). Conclusion. The incidence and mortality rate of kidney cancer is higher in developed countries. A significant positive correlation has been seen between the standardized incidence and mortality rate of kidney cancer with the Human Development Index and its components. We need more studies to examine variation in incidence and mortality of kidney cancer and its related factors in the world.

Background: Recently, reports have suggested that rates of liver cancer have increased during the last decades in developed countries; increasing hepatocellular carcinoma and cholangiocarcinoma rates were reported. The aim of this study was to examine time trends in incidence and mortality rates of liver cancer for the period of 1998–2015 in Lithuania by sex, age, and histology. Methods: We examined the incidence of liver cancer from 1998 to 2015 using data from the Lithuanian Cancer Registry. Age-standardized incidence rates were calculated by sex, age, and histology. Trends were analyzed using the Joinpoint Regression Program to estimate the annual percent change. Results: A total of 3086 primary liver cancer cases were diagnosed, and 2923 patients died from liver cancer. The total number of liver cancer cases changed from 132 in 1998 to 239 in 2015. Liver cancer incidence rates changed during the study period from 5.02/100,000 in 1998 to 10.54/100,000 in 2015 in men and from 2.43/100,000 in 1998 to 6.25/100,000 in 2015 in women. Annual percentage changes (APCs) in the age-standardized rates over this period were 4.5% for incidence and 3.6% for mortality. Hepatocellular cancer incidence rates were stable from 1998 to 2005 (APC −5.9, p = 0.1) and later increased by 6.7% per year (p < 0.001). Intrahepatic ductal carcinoma incidence increased by 8.9% per year throughout the study period. The rise in incidence was observed in all age groups; however, in age groups < 50 and between 70 and 79 years, observed changes were not statistically significant. For mortality, the significant point of trend change was detected in 2001, where after stable mortality, rates started to increase by 2.4% per year. Conclusions: Primary liver cancer incidence and mortality increased in both sexes in Lithuania. The rise om incidence was observed in both sexes and main histology groups. The increasing incidence trend may be related to the prevalence of main risk factors (alcohol consumption, hepatitis B and C infections. and diabetes).

Objective: To evaluate the trends of colorectal cancer (CRC) incidence and mortality rates from 2003 to 2014 in Italy by age groups and regions. Methods: We used the data of 48 cancer registries from 17 Italian regions to estimate standardized incidence and mortality rates overall and by sex, age groups (<50, 50–69, 70+ years), and geographic area (northwest, northeast, center, south, and islands). Time trends were expressed as annual percent change in rates (APC) with 95% confidence intervals (95% CI). Results: Incidence rates decreased from 104.3 (2003) to 89.9 × 100,000 (2014) in men and from 64.3 to 58.4 × 100,000 in women. Among men, incidence decreased during 2007–2010 (APC −4.0, 95% CI −6.0 to −1.9) and 2010–2014 (APC −0.7, 95% CI −1.4 to 0.0), while in women it linearly decreased during the whole period (APC −1.1, 95% CI −1.4 to −0.8). Mortality rates showed a linear reduction both in men (APC −0.7, 95% CI −1.0 to −0.3) and women (APC −0.9, 95% CI −1.2 to −0.6) and decreased respectively from 41.1 to 39.2 × 100,000 and from 24.6 to 23.1 × 100,000. In the 50- to 69-year-old range (screening target age), incidence showed a prescreening increase, followed by a peak after screening started, and a decline thereafter. Incidence and mortality rates significantly decreased in all areas but in the south and islands, where incidence increased and mortality remained stable. Conclusions: A renewed commitment by all regional health systems to invest in primary (i.e., lifestyle) and secondary (i.e., screening programs) prevention is of utmost importance.

Abstract Background The accurate information about burden of multiple myeloma (MM) at national and provincial level remains unknown in China. Methods Following the general analytical strategy used in GBD 2016, the age-, sex-, and province-specific incidence and mortality in China were analyzed. Trends in the incidence and mortality from 2006 to 2016 were evaluated. Results It was estimated that there were 16,500 new cases and 10,300 deaths of multiple myeloma in China in 2016. The age-standardized incidence rates (ASIR) and mortality rates (ASMR) per 100,000 population were 1.03 (95% UI, 0.88–1.17) and 0.67 (95% UI, 0.59–0.77) in 2016. Males had higher incidence and mortality rates than females in all age groups. An upward trend with age in incidence and mortality was observed. Higher incidence and mortality rates clustered in the developed provinces. The incidence of MM in China increased significantly from 2006 to 2016, while the mortality increased from 2006 to 2014, and remained stable from 2014 to 2016. Conclusion The burden of MM showed a heterogeneous pattern in China, which highlighted the need of tailored disease prevention and control strategies in both national and provincial levels.

Background. Cancer is a leading cause of death in children and adolescents worldwide. The cancer incidence rate in children and adolescents has been on the rise for decades. Climatic, geographic and social factors of the region play an important role for cancer incidence.Objective: to analyze the cancer incidence and mortality rates in children and adolescents of Prymorsky krai.Methods. Cancer incidence rates in Russia for 2008–2018 as well as cancer incidence among children treated at the regional pediatric hematology/oncology center (Vladivostok, Russia) for 2014–2019 were analyzed.Results. No statistically significant differences in the cancer incidence rates for the 2008–2018 period between children and adolescents of Primorsky krai and the russian federation in the whole and the far-eastern federal district were found. In in Primorsky krai, there was a variability in the incidence rate during the analyzed period, a negative average annual growth rate in the group of children under 14 years of age (-0.86 %). For the 2008–2018 period, the cancer mortality rate in children and adolescents of Primorsky krai significantly decreased (from 5.65 ‰ in 2008 to 2.6 ‰ in 2018), with the average annual increase rate in children aged 017 years of -9.17 %. In 2014–2019, the quality of cancer detection improved significantly, and the number of children and adolescents with stage iiiiv cancer reduced.Conclusion. Cancer prevention and early detection can potentially reduce the cancer incidence and mortality rates in children and adolescents in Primorsky krai. Population-based cancer registries are needed for quantifying the burden of cancer in children and adolescents and assessing prevention and control programs.

Background: Several countries have documented the relationship between long-term exposure to air pollutants and epidemiological indicators of the COVID-19 pandemic, such as incidence and mortality. This study aims to explore the association between air pollutants, such as PM2.5 and PM10, and the incidence and mortality rates of COVID-19 during 2020. Methods: The incidence and mortality rates were estimated using the COVID-19 cases and deaths from the Chilean Ministry of Science, and the population size was obtained from the Chilean Institute of Statistics. A chemistry transport model was used to estimate the annual mean surface concentration of PM2.5 and PM10 in a period before the current pandemic. Negative binomial regressions were used to associate the epidemiological information with pollutant concentrations while considering demographic and social confounders. Results: For each microgram per cubic meter, the incidence rate increased by 1.3% regarding PM2.5 and 0.9% regarding PM10. There was no statistically significant relationship between the COVID-19 mortality rate and PM2.5 or PM10. Conclusions: The adjusted regression models showed that the COVID-19 incidence rate was significantly associated with chronic exposure to PM2.5 and PM10, even after adjusting for other variables.

Introduction. Lung cancer represents the most common malignant tumour among men, and appears more and more frequently among women in many countries worldwide. The aims of this descriptive epidemiological study were to evaluate the mortality trends of all malignant tumours and lung cancer in Central Serbia from 1990 to 1999, and to estimate the incidence, mortality and the basic demographic characteristics of lung cancer in Central Serbia in 1999. Material and methods. The source of data concerning cancer cases in 1999 was the Cancer Registry of Central Serbia, while data of the Republic Statistics Institute were used for the analysis of mortality trends for the period 1990-1999. All rates were standardized by the direct method, to the world standard population. Confidence intervals for mortality rates were assessed with 95% level of probability. Linear regression coefficient was determined by Fisher's test. Results. The mortality rates showed rising tendencies for both lung cancer (y=-1876.26+0.96x, p=0.028 for men; y=654.78U).33x, p-0.001 for women) and all malignant tumours (y=-4139.88+2.15x, p=0.163 for men; y=3649.68 + 1.88x, p=0.016 for women), with statistically significant increase being observed for all trends, except all malignant tumours among men. In the year 1999, lung cancer ranked first among men and third among women, with 29.2% and 10.3% of cancer mortality respectively. The age-specific mortality rates were much higher in men in all age groups. Mortality increased with age and the highest rates were found in the age group 70-74 for both sexes. The highest incidence and mortality rates were reported in Belgrade, Moravicki and Sumadijski district. .
