Epidemiology of pancreatic cancer in Ukraine and Zaporizhzhia region

Pancreatic cancer (PC) is the third leading cause of all cancer-related fatalities and accounts for approximately 3% of cancer cases in the United States. PC survival rates are lower in Blacks compared to other races, and this has been attributed to socioeconomic and genetic factors. In this study, we evaluated sociodemographic and genetic characteristics associated with PC incidence and mortality among Blacks. Data from the SEER 22 registries (2000-2020) were used to calculate the incidence rates and relative survival. County mortality rates from 2017 to 2021 were analyzed. Incidence rate ratios based on gender, age, primary disease site, stage, level of education, and poverty were calculated. Survival analysis was conducted using the Kaplan-Meier method. Mutant gene expression was obtained from the MSK-CHORD tumor registry. Overall, 48,606 Black patients were diagnosed with malignant PC between 2000 and 2020: females (53.53%) and males (46.47%). Both males and females experienced a slight increase in Annual Percent Change (APC) of PC incidence (0.24, 95% CI, -0.02-0.53) and (0.22, 95% CI, -0.05-0.51), respectively, from 2000 to 2020. Males aged 55 to 75 years were most frequently affected. Overall incidence risk from 2000-2020 by age was higher in Black males IRR > 1 (1.18, 95% CI, 1.16-1.21). The most common primary PC site for Black males and females was the head of the pancreas, 49.06% and 49.88%, respectively. By staging, distant PC had the highest frequency in Blacks. Poverty level was associated with PC incidence among females and PC mortality among both males and females. Stage was associated with survival among males with localized and regional PC. The 5-year relative survival was less than 11% across combined PC stages for both sexes. Black males had a relatively lower 5-year survival than Black females in localized (31.7 vs. 37.2%) and distant PC (2.6% vs. 2.90%). Mutant KRAS expression was higher in Black males. PC incidence and mortality were significantly higher in Black males. Our analysis points to the importance of poverty alleviation programs that target females are likely to reduce PC incidence. Furthermore, receiving recommended screening for PC and early-stage diagnostics is important to lower PC mortality.

Pancreatic cancer is the fourth leading cause of cancer-related mortality in the United States. Descriptive epidemiology of pancreatic cancer in South Dakota has not been studied before. All cases of pancreatic cancer reported to the SD Cancer Registry between January 2005 and December 2014 were included in the study. Variables collected included demographics, geographical location including county of residence and zip codes, date of diagnosis, date of last contact or follow-up, size and location of the tumor, grade of the tumor, diagnostic modality as well as therapeutic interventions. Log rank test was used to compare survival curves. Kaplan-Meier product limit estimates were provided. Data was analyzed using SAS 9.1.4 software. One thousand sixty-four cases of pancreatic cancer were reported. Median age was 73years. Cumulative age-adjusted incidence rate for pancreatic cancer for 2005-2014 was 11.1. Cumulative age-adjusted mortality rate for pancreatic cancer for 2005-2014 was 10.2. Almost half of these patients had distant metastasis at the time of presentation (n = 536; 50.4%). Overall, median survival was 5months. Median survival for patients under the age of 60years was 9.5months as opposed to median survival for patients 60years or older which was 3.9months. Median survival of patients with well-differentiated, moderately differentiated, and poorly differentiated tumors, was 20.8months, 8.2months and 6.3months respectively (p value = 0.0017). Incidence of pancreatic cancer in South Dakota is similar to the national trends in the United States. Age at presentation, location of tumor in pancreas, and biological behavior of tumor were all predictors of survival in patients with pancreatic cancer.

Pancreatic cancer is one of the deadliest cancers with short-term survival rates. Trends for pancreatic cancer incidence and mortality varied considerably in the world. To date, the causes of pancreatic cancer are not known sufficiently, although certain risk factors have been identified such as, smoking, obesity, life style, diabetes mellitus, alcohol, dietary factors and chronic pancreatitis. Since there are no current screening recommendations for pancreatic cancer, primary prevention is very important. Therefore, up-to-date statistics on pancreatic cancer occurrence and outcome are essential for the primary prevention of this disease. Due to the lack of information on epidemiology of pancreatic cancer in most Asian countries, and limited of statistics and registration system in this area, we conducted a systematic review study to evaluate the most recent data concerning epidemiology of pancreatic cancer in Asia-Pacific region. In this review we focused on collected recent data on incidence, mortality, survival and risk factors of pancreatic cancer in this region. In addition, we reviewed and used the data of GLOBOCAN 2012 in this paper to complete the information as a source of compiling pancreatic cancer incidence and mortality rate.

To the Editors: Sinner et al. ([1][1]) report a lack of association between obesity and pancreatic cancer in a cohort study of elderly women with 209 cases of pancreatic cancer. These results are valuable given the prospective nature of the study. However, we disagree with the authors' conclusion

Advances in the epidemiology of pancreatic cancer: Trends, risk factors, screening, and prognosis.

The aim of this study was to describe period and cohort effects in incidence and mortality of stomach and pancreatic cancer in England and Wales. National figures for mortality (1951-2000) and incidence (1971-2000) were analysed using log-linear Poisson regression models to obtain relative risks (RR) for period (year of incidence or death) and cohort (year of birth). Stomach cancer shows a pronounced cohort effect in mortality with a decline in RR in men from 2.20 (1876) to 0.47 (1946) and a reduction from 2.79 to 0.41 for women. Mortality to incidence ratios are now less than 0.70. Pancreatic cancer mortality (men) RR rose from 0.91 (1951-1955) to a peak 1.11 (1976-1980) and then declined to 0.90 (1996-2000). Women showed a similar pattern. Cohort RR (men) increased to a peak of 1.14 in 1916 and declined to 1.01 in 1946, and continued to fall; the peak occurred slightly later in women. Mortality to incidence ratios were near 1 in the first 20 years, declining to 0.95 in the last 10 years. Stomach cancer incidence has fallen continuously from 19(th) century birth cohorts onwards. Incidence of pancreatic cancer has fallen in successive birth cohorts after 1920; peak period risk was 1976-1990. Age-standardized mortality and case mortality for pancreatic cancer are declining.

Background: Physical activity has been associated with a lower risk of various types of cancer and reduced cancer-specific mortality. Less is known about its impact on pancreatic cancer. The aim of this systematic review and meta-analysis was to summarize evidence on the association between physical activity and pancreatic cancer risk and mortality. Methods: PubMed and Embase were searched until May 2024 for studies examining physical activity in relation to pancreatic cancer incidence and mortality. Summary risk estimates for highest vs. lowest physical activity levels were calculated using a random-effects model. The risk of publication bias was assessed with a funnel plot and Egger's regression test. Results: A total of seven case-control and eighteen prospective cohort studies were included that investigated the association between physical activity and pancreatic cancer incidence. Our meta-analysis showed a summary estimate of 0.75 (95% CI 0.64-0.88) for case-control studies (I2 = 23%, n = 7) and a summary estimate of 0.91 (95% CI 0.86-0.97) for prospective cohort studies (I2 = 5%, n = 18). Among the six prospective cohort studies that assessed pancreatic cancer mortality, the summary estimate was 1.03 (95% CI 0.83-1.27), I2 = 50%. Conclusions: Higher levels of physical activity were associated with reduced pancreatic cancer risk. Evidence from a limited number of studies suggests that pre-diagnosis physical activity does not affect pancreatic cancer mortality.

Introduction: Pancreatic cancer is a highly mortal disease that used to be rare but its incidence rate has increased in the last few decades. Despite declining overall cancer incidence and mortality rates in developed countries, pancreatic cancer tends to increase in both incidence and mortality. Previous studies showed a male predominance in pancreatic cancer in patients older than 35. However, considering the sudden rise in incidence in young females, a new survey is crucial to address the current pattern of pancreatic cancer distribution between males and females. Hormonal factors may play a role in the pathogenesis of pancreatic cancer. Objectives: This study aimed to evaluate the role of gender differences in mortality and incidence of pancreatic cancer in an ecological study based on data extracted from the GLOBOCAN project in 2020. Patients and Methods: An ecological study was carried out to assess gender disparity in pancreatic cancer incidence and mortality rates. The data used in the study were obtained from the Global Cancer (GLOBOCAN) project of the World Health Organization (WHO) in 2020 (https://gco.iarc.fr/). Results: The pancreatic cancer mortality rate worldwide (2020) was estimated at 466,003 cases, encompassing 246,840 cases (52.96%) among males and 219,163 cases (47.04%) among females. The study found that although there were differences in the mean pancreatic cancer incidence and mortality rates between males and females when measured by indicators such as number, ASR, and crude rate, these differences were not statistically significant. Conclusion: In conclusion, the pancreatic cancer incidence and mortality rate is increasing worldwide. In spite of the fact that men die from pancreatic cancer at a higher rate than women, there is no statistically significant difference between the two. Registration: The study protocol was registered on the Research Registry website with the unique identification number (UIN) researchregistry9598.

BACKGROUNDPancreatic cancer, as the one of most fatal malignancies, remains a critical issue in the global burden of disease.AIMTo estimate trends in pancreatic cancer incidence and mortality worldwide in the last three decades.METHODSA descriptive epidemiological study was done. Pancreatic cancer incidence and mortality data were obtained from the database of the World Health Organization. Analysis of pancreatic cancer incidence and mortality during 2020 was performed. The age-standardized rates (ASRs, expressed per 100000) were presented. To estimate trends of incidence and mortality of pancreatic cancer, joinpoint regression analysis was used: the average annual percent change (AAPC) with the corresponding 95% confidence interval (95%CI) was calculated. Additionally, analysis was performed by sex and age. In this paper, the trend analysis included only countries with high and medium data quality.RESULTSA total of 495773 (262865 male and 232908 female) new cases and 466003 (246840 male and 219163 female) deaths from pancreatic cancer were reported worldwide in 2020. In both sexes, most of the new cases (191348; 38.6% of the total) and deaths (182074; 39.1% of the total) occurred in the Western Pacific Region. In both sexes, the highest ASRs were found in the European Region, while the lowest rates were reported in the South-East Asia Region. The general pattern of rising pancreatic cancer incidence and mortality was seen across countries worldwide in observed period. Out of all countries with an increase in pancreatic cancer incidence, females in France and India showed the most marked rise in incidence rates (AAPC = +3.9% and AAPC = +3.7%, respectively). Decreasing incidence trends for pancreatic cancer were observed in some countries, but without significance. Out of all countries with an increase in pancreatic cancer mortality rates, Turkmenistan showed the most marked rise both in males (AAPC = +10.0%, 95%CI: 7.4–12.5) and females (AAPC = +6.4%, 95%CI: 3.5–9.5). The mortality trends of pancreatic cancer were decreasing in both sexes only in Canada and Mexico.CONCLUSIONFurther research is needed to explain the cause of large international differences in incidence and mortality trends of pancreatic cancer in last three decades.

Cancer of the pancreas remains one of the deadliest cancer types. Based on the GLOBOCAN 2012 estimates, pancreatic cancer causes more than 331000 deaths per year, ranking as the seventh leading cause of cancer death in both sexes together. Globally, about 338000 people had pancreatic cancer in 2012, making it the 11th most common cancer. The highest incidence and mortality rates of pancreatic cancer are found in developed countries. Trends for pancreatic cancer incidence and mortality varied considerably in the world. A known cause of pancreatic cancer is tobacco smoking. This risk factor is likely to explain some of the international variations and gender differences. The overall five-year survival rate is about 6% (ranges from 2% to 9%), but this vary very small between developed and developing countries. To date, the causes of pancreatic cancer are still insufficiently known, although certain risk factors have been identified, such as smoking, obesity, genetics, diabetes, diet, inactivity. There are no current screening recommendations for pancreatic cancer, so primary prevention is of utmost importance. A better understanding of the etiology and identifying the risk factors is essential for the primary prevention of this disease.

Total antioxidant capacity (TAC) reflects an individual's overall antioxidant intake. We sought to clarify whether higher TAC is associated with lower risks of pancreatic cancer incidence and mortality in the U.S. general population. A total of 96,018 American adults were identified from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. A ferric-reducing ability of plasma score was used to reflect an individual's TAC intake from diet and/or supplements. Cox regression was used to calculate hazard ratios (HR) for pancreatic cancer incidence, and competing risk regression was used to calculate subdistribution HRs for pancreatic cancer mortality. Restricted cubic spline regression was used to test nonlinearity. A total of 393 pancreatic cancer cases and 353 pancreatic cancer-related deaths were documented. Total (diet + supplements) TAC was found to be inversely associated with pancreatic cancer incidence (HR quartile 4 vs. quartile 1 = 0.53; 95% confidence interval, 0.39-0.72; P trend = 0.0002) and mortality (subdistribution HR quartile 4 vs. quartile 1 = 0.52; 95% confidence interval 0.38-0.72; P trend = 0.0003) in a nonlinear dose-response manner (all P nonlinearity < 0.01). Similar results were observed for dietary TAC. No association of supplemental TAC with pancreatic cancer incidence and mortality was found. In the U.S. general population, dietary but not supplemental TAC level is inversely associated with risks of pancreatic cancer incidence and mortality in a nonlinear dose-response pattern. This is the first prospective study indicating that a diet rich in antioxidants may be beneficial in decreasing pancreatic cancer incidence and mortality.

In the United States the incidence of and mortality from pancreatic cancer have increased over the past several decades but have tended to level off in recent years. The rates are higher in blacks than in whites and higher in males than in females. Mortality rates increase with age but there appears to be a decline in elderly blacks, possibly on an artifactual basis. There is a suggestion that rates are higher in Jews. No consistent differences by socioeconomic status or by geographic location within the United States have been identified. Both genetic and environmental factors may be playing significant roles in this disease. Cigarette smoking may be etiologically related, or at the very least, may help to identify a group of patients at increased risk of pancreatic cancer. However, the relative risk estimated for cigarette smoking is much lower than that found for cancer of the lung. The leveling off in incidence and mortality rates for pancreatic cancer in recent years also differs from the time trends observed for lung cancer. However, this could result from differences in site‐specific carcinogens and from the fact that the lung is the first organ to be exposed to cigarette smoke in the highest concentrations and prior to the metabolism of any of its components.Dietary factors may have an important role in pancreatic cancer, but further research is needed to clarify this relationship. In particular, the possibility that dietary fats may be implicated and that vitamins or fiber may be protective in this disease remains to be explored. Finally, there is suggestive evidence that specific chemical exposures may be carcinogenic for the pancreas. Many of the data are from animal studies, and the findings from human studies are not entirely consistent.
