Kreft og dødelighet blant norske feiere: Vurdering av datakvalitet

ENGLISH SUMMARYMøller B, Andersen Aa. Cancer and mortality among Norwegian chimney sweeps.Nor J Epidemiol 2001; 11 (2): 193-196.The aim of the study was to investigate cancer incidence and mortality among Norwegian chimneysweeps. A cohort of 1483 persons was established by collecting information about current and formerchimney sweeps from all the local authorities. Information from housing censuses (HS) in 1960, 1970and 1980 were used to study the quality of the data. This revealed that the mortality among those chimneysweeps in HS that are included in our cohort is lower than the mortality among those not reportedto us from the local authorities. Because of this, only a sub-cohort of 287 chimney sweeps from thelargest cities were considered reliable. The uncertainty concerning risks for the different cancer sites inthis group is large, since calculations are based on very few cases. The standardized incidence rate(SIR) for total cancer is 1.3 (95% CI: 1.0–1.8), and the standardized mortality rate (SMR) for all deathsis 1.2 (95% CI: 1.0–1.4). We also analyzed the 1292 persons who stated chimney sweep as occupationin the housing censuses in 1960, 1970 or 1980. SIR and SMR analyses in this group show no increasedrisk for any specific cancer sites, nor for any cause specific death.

Introduction: Understanding the epidemiology of Esophageal Cancer (EC) seems to be essential in order to plan and control it. The aim of this study was to investigate the incidence and mortality rate of EC and its relationship with the worldwide Human Development Index (HDI) of 2012. Methods: This study was an ecological study which assessed the correlation of age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of EC with HDI and its components. ASIR and ASMR data for EC were extracted from the global cancer project for the year 2012. Statistical analyses were performed by SPSS 16. Results: From EC were recorded worldwide in 2012, there was a total of 455,784 incidents of EC (70.86% males and 29.14% females; ratio of males to females was 2.43:1) and 400,169 mortalities (70.27% males and 29.73% females; ratio of males to females was 2.36:1). The correlation between HDI and SIR was -0.121 (p=0.105); with -0.061 (p=0.415) for men and -0.190 (p=0.010) for women. Moreover, the correlation between HDI and SMR was -0.156 (p=0.036), with -0.101 (p=0.180) for men and -0.218 (p=0.003) for women. Conclusion: The incidence and mortality rates from EC is higher in less developed or developing countries. No statistically significant correlation was seen between the standardized mortality or incidence rates of EC and the 2012 HDI.

Khanty Mansi Autonomous

The aim of the study was to assess the lung cancer incidence and mortality in the Khanty-mansi autonomous okrug – Yugra during the period 1999–2019.Material and methods. We have studied the lung cancer incidence and mortality rates in Yugra over the last 21 years (1999–2019).Results. In Yugra, the lung cancer (lc) incidence rates increased by 24.7 % from 1999 to 2019, demonstrating higher rates than those in the Russian Federation (RF), where lc incidence rates decreased by 20.3 %. In 2019, the age-standardized incidence rate was 30.5 per 100,000 (22.7 for RF); the age-standardized mortality rate was 16.4 per 100,000 (18.4 for RF). The mortality rate from lc in Yugra was 9.6 times higher in males than in females (35.5 vs. 3.7 per 100,000). The cross-correlation analysis revealed a correlation between the lc incidence/mortality and air pollution in Yugra. The main carcinogens in Yugra were formaldehyde, phenol, nitrogen dioxide, and benzapyrene. The assessment of the relationship between the age-standardized lc incidence/mortality rates and the amount of pollutants emitted into the atmosphere revealed that their synergistic effects with tobacco smoking can double the risk of lung cancer development. The increase in the number of chest computed tomography (ct) scans performed in the context of the pandemic caused by covid-19 infection led to an 18 % increase in the number of incidentally detected pulmonary nodules, of which 9 % of cases were diagnosed as lc.Conclusion. The lc incidence rates in Yugra tended to increase. The high rate of lc incidence is caused by man-made and natural factors, which requires the implementation of a screening program with the use of low-dose computed tomography in order to improve the early detection and prevention of this disease.

The Impact

Abstract Objective A previous Australian study compared the observed numbers of cancer cases and deaths in 2007 with the expected numbers based on 1987 rates. This study examines the impact of cancer rate changes over the 20-year period 1996–2015, for people aged under 75 years. Results The overall age-standardised cancer incidence rate increased from 350.7 in 1995 to 364.4 per 100,000 in 2015. Over the period 1996–2015, there were 29,226 (2.0%) more cases (males: 5940, 0.7%; females: 23,286, 3.7%) than expected numbers based on 1995 rates. Smaller numbers of cases were observed compared to those expected for cancers of the lung for males and colorectum, and cancers with unknown primary. Larger numbers of cases were observed compared to those expected for cancers of the prostate, thyroid and female breast. The overall age-standardised cancer mortality rate decreased from 125.6 in 1995 to 84.3 per 100,000 in 2015. During 1996 to 2015 there were 106,903 (− 20.6%) fewer cancer deaths (males: − 69,007, − 22.6%; females: − 37,896, − 17.9%) than expected based on the 1995 mortality rates. Smaller numbers of deaths were observed compared to those expected for cancers of the lung, colorectum and female breast, and more cancer deaths were observed for liver cancer.

Risk Of Cancer

Epidemiological studies have suggested inconclusive associations between 25-hydroxyvitamin D and total cancer incidence and mortality. The aim of this study was to quantitatively assess these associations by combining results from prospective cohort studies. A systematic literature search was implemented in PubMed and Scopus databases in April 2019. Comparing the highest with the lowest categories, the multivariate-adjusted relative risks (RRs) and the corresponding 95% confidence intervals (CIs) were pooled using a random-effects model. A trend estimation was performed using a two-stage, dose-response, meta-analysis method. Twenty-three independent prospective studies were included for data synthesis. Eight studies investigated the association between 25-hydroxyvitamin D and the risk of cancer incidence (7511 events and 70,018 participants), and the summary estimate showed that 25-hydroxyvitamin D is marginally associated with cancer risk (Summary RR = 0.86; 95% CI: 0.73, 1.02; I2 = 70.8%; p = 0.001). Sixteen studies investigated the association between 25-hydroxyvitamin D and the risk of cancer mortality (8729 events and 101,794 participants), and a higher 25-hydroxyvitamin D concentration was inversely associated with the risk of cancer mortality (Summary RR = 0.81; 95% CI: 0.71, 0.93; I2 = 48.8%, p = 0.012). Dose-response analysis indicated that the risk of cancer incidence was reduced by 7% (RRs = 0.93; 95% CI: 0.91, 0.96), and the risk of cancer mortality was reduced by 2% (RRs = 0.98; 95% CI: 0.97, 0.99), with each 20 nmol/L increment of 25-hydroxyvitamin D concentration. This meta-analysis provides evidence that a higher 25-hydroxyvitamin D concentration is associated with a lower cancer incidence and cancer mortality.

Abstract The world’s population is aging rapidly. This study reports the burden of cancer in the oldest old (≥85 years) in Finland in 1953-2017 and estimates age-specific cancer rates in the old population (65-99 years) in 1988-2017. The Finnish Cancer Registry provided data on all cancer diagnoses, cancer deaths and other deaths in cancer patients in Finland in 1953-2017. Between 1953-1957 and 2013-2017, the proportion of incident cancers in those aged ≥85 years increased from 1.5% to 9.6% (597 to 15,360 new cases), and in 2013-2017, more new cancers were diagnosed at age ≥85 years than age <50 years. Cancer incidence and excess mortality attributable to cancer peaked at age 85-94 years and declined subsequently, whereas cancer-specific mortality continued to increase or plateaued. Due to demographic changes, the number of new cancers in the oldest old has increased substantially in Finland, and currently, nearly one in 10 cancers are diagnosed in this age group. The increasing cancer burden in the oldest old poses a major challenge for healthcare and needs to be addressed in designing clinical research and reporting of cancer registries. In old populations with competing risks of death, we propose excess cancer mortality as a measure of cancer-related mortality.

Abstract Background Physical activity has been associated with reduced risk of seven types of cancer. It remains unclear, however, whether muscle-strengthening activities also reduce cancer incidence and mortality. Methods PubMed, Embase, Web of Science and Scopus were searched from inception to March 2020. Summary hazard ratio (HR) and 95% confidence intervals (CI) were estimated using random-effects models. Results Twelve studies (11 cohorts; 1 case-control), 6 to 25 years of follow-up, including 1,297,620 participants, 32,196 cases and 31,939 deaths, met inclusion criteria. Muscle-strengthening activities were associated with a 26% lower incidence of kidney cancer (HR for high vs low levels of muscle-strengthening activities: 0.74; 95% CI 0.56 to 0.98; I2 0%; 2 studies), but not with incidence of other 12 types of cancer. Muscle-strengthening activities were associated with lower total cancer mortality: HRs for high vs low levels of muscle-strengthening activities was 0.87 (95% CI 0.73 to 1.02; I2 58%; 6 studies); and HR for ≥2 times/week vs < 2 times/week of muscle-strengthening activities was 0.81 (95% CI 0.74 to 0.87; I2 0%; 4 studies). Regarding the weekly duration of muscle-strengthening activities, HR for total cancer mortality were 0.91 (95% CI 0.82 to 1.01; I2 0%; 2 studies) for 1–59 min/week and 0.98 (95% CI 0.89 to 1.07; I2 0%) for ≥60 min/week vs none. Combined muscle-strengthening and aerobic activities (vs none) were associated with a 28% lower total cancer mortality (HR 0.72; 95% CI 0.53 to 0.98; I2 85%; 3 studies). Conclusions Muscle-strengthening activities were associated with reduced incidence of kidney cancer and total cancer mortality. Combined muscle-strengthening and aerobic activities may provide a greater reduction in total cancer mortality.
