The disease burden of bladder cancer and its attributable risk factors in five Eastern Asian countries, 1990-2019: a population-based comparative study. BMC Public Health 2024; 24:2404. [PMID: 39232688 PMCID: PMC11373407 DOI: 10.1186/s12889-024-19909-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 08/27/2024] [Indexed: 09/06/2024] Open
Abstract
BACKGROUNDS The study aimed to estimate bladder cancer burden and its attributable risk factors in China, Japan, South Korea, North Korea and Mongolia from 1990 to 2019, to discuss the potential causes of the disparities. METHODS Data were obtained from the Global Burden of Disease Study 2019. The annual percent change (APC) and average annual percent change (AAPC) were calculated by Joinpoint analysis, and the independent age, period and cohort effects were estimated by age-period-cohort analysis. RESULTS In 2019, the highest incidence (7.70 per 100,000) and prevalence (51.09 per 100,000) rates of bladder cancer were in Japan, while the highest mortality (2.31 per 100,000) and DALY rates (41.88 per 100,000) were in South Korea and China, respectively. From 1990 to 2019, the age-standardized incidence and prevalence rates increased in China, Japan and South Korea (AAPC > 0) and decreased in Mongolia (AAPC < 0), while mortality and DALY rates decreased in all five countries (AAPC < 0). Age effects showed increasing trends for incidence, mortality and DALY rates, while the prevalence rates increased first and then decreased in older groups. The cohort effects showed downward trends from 1914-1918 to 2004-2008. Smoking was the greatest contributor and males had the higher burden than females. CONCLUSION Bladder cancer was still a major public health problem in East Asia. Male and older population suffered from higher risk, and smoking played an important role. It is recommended that more efficient preventions and interventions should be operated among high-risk populations, thereby reduce bladder cancer burden in East Asia.

Abstract
BACKGROUND Childhood leukemia (CL) is a major global concern, accounting for 33% of all new cancer cases and 31% of all cancer deaths in children aged 0-14 years. Our study aimed to analyze the global incidence and mortality rates of CL in 2020 and its relationship with the Human Development Index (HDI). MATERIAL AND METHODS In this ecologic study, we analyzed the 2020 cancer incidence and mortality data for children aged 0-14 years from the GLOBOCAN Project. We calculated the Age-Standardized Incidence Rate (ASIR) and Age-Standardized Mortality Rate (ASMR) of CL per 100,000 individuals. Pearson's correlation coefficient was used to examine the association between childhood leukemia ASIR, ASMR, and the HDI, with a statistical significance threshold of P<0.05. RESULTS In 2020, there were a total of 67,008 new cases of CL worldwide, with males accounting for 57.85%. The global ASIR for CL was 3.4 per 100,000 (3.9 in males, 3 in females). Additionally, there were 25,080 CL-related deaths, with males comprising 58.86%. The overall ASMR for CL was 1.3 (1.4 in males, 1.1 in females). We found a significant positive correlation (r = 0.405, P≤0.001) between the global ASIR and ASMR for CL. There was a strong positive correlation (r = 0.770, P = 0.001) between the HDI and childhood leukemia ASIR, but no significant association (r = 0.077, P = 0.337) was observed with ASMR. CONCLUSION Our study reveals that CL remains a significant health burden worldwide. We identified a positive correlation between the ASIR of CL and the HDI, indicating a potential role of socioeconomic factors in CL incidence.

Abstract
The aim is to analyze the trend in breast cancer mortality rates and its correlation with the socioeconomic development status in Brazil. It involved an ecological time series study carried out in the 26 units of the federation, Federal District and regions of Brazil. Data sources included the Mortality Information System (number of deaths), the Brazilian Institute of Geography and Statistics (resident population) and the study of the Global Burden of Disease (Socio-demographic Index - SDI). Data from 2005 to 2019 were used. The trend was analyzed using Prais-Winsten regression models. The relationship between the mortality rate and the SDI was analyzed using Spearman's correlation coefficient. During the study period, 207,683 deaths from breast cancer occurred. The average standardized mortality rate was 19.95 deaths per 100,000 women in Brazil. All the regions of Brazil showed an increasing trend in mortality. Of the total federative units, 22 showed an increasing trend. There was a positive relationship between the mortality rate and the SDI. The standardized mortality rate for breast cancer showed an increasing trend in Brazil, in all regions and in most states. There was a direct association between mortality and SDI, indicating a greater magnitude in more developed regions.

Burden of esophageal cancer between 2010 and 2019 in Asian countries by geographical region and sociodemographic index: A comparison with global data. Thorac Cancer 2023; 14:2361-2407. [PMID: 37455657 PMCID: PMC10447175 DOI: 10.1111/1759-7714.15026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 06/19/2023] [Accepted: 06/20/2023] [Indexed: 07/18/2023] Open
Abstract
BACKGROUND The aim of this study was to describe the trends in incidence, mortality, and burden of esophageal cancer (EC) in Asia from 2010 through 2019 and compare with other global continental data. METHODS We collected EC data from the 2019 Global Burden of Disease study from 2010 to 2019 in 49 countries and territories in Asia based on the sociodemographic index (SDI). For all locations, annual case data and age-standardized rates (ASRs) were extracted to investigate the EC incidence, prevalence, mortality, and disability-adjusted life-years (DALYs). The ASR relative difference (%) between years and the male/female (M/F) ratio were calculated. Data are reported in values and 95% uncertainty interval (UI). RESULTS In 2019, more than 70% of EC new cases, deaths, prevalence, and DALYs occurred in Asian countries. From 2010 to 2019, incidences, deaths, prevalence cases, and DALY number of EC increased over 1.10-, 1.07-, 1.14-, and 1.03-fold, in Asia. During this period, the age-standardized incidence rate (ASIR), age-standardized death rate (ASDR), age-standardized prevalence rate (ASPR), and age-standardized DALYs rate (DALYs ASR) of EC decreased by 18, 21, 14, and 22%, respectively. The rate of decline in Asia is higher than in the world and other continents. In 2019, age-specific incidence, death, prevalence, and DALY cases of EC cancer peaked at 65-74, 70-74, 65-69, and 65-69 years, respectively. In 2019, the highest ASIR, ASDR, ASPR, and DALYs ASR of EC were observed in East Asian countries, while having the highest decreasing trend. In 2019, among high SDI Asian countries, Taiwan had the highest ASIR, ASPR, and DALYs ASR, and the United Arab Emirates had the highest ASDR. Among high-middle SDIs, Kazakhstan had the highest ASIR, ASPR, ASDR, and DALYs ASR; among middle SDIs, China had the highest ASIR, ASDR, and ASPR, and Viet Nam had the highest DALYs ASR; among low-middle SDIs, Mongolia had the highest ASIR, ASDR, ASPR, and DALY ASR of EC cancer. Among low SDI Asian countries, Pakistan had the highest ASIR and ASPR, and DALY ASR for EC cancer. For four indicators, in most countries, the ratio of men was higher than women, and in some countries, this ratio reached more than 10 times. CONCLUSION Although the rate of decline in incidence, death, prevalence and burden of EC in Asia was higher than in other areas in the last 10 years, more than 70% of these amounts occur in Asia. Therefore, it appears that adopting appropriate strategies in the field of identifying and controlling modifiable risk factors for EC, implementing screening programs, and timely diagnosis and treatment will help in reducing the burden of this disease in Asian countries.

Assessment of Tolerability, Response and Complications of Concurrent Chemoradiation With Capecitabine and Cisplatin in Muscle-Invasive Bladder Cancer; A Single Arm Study. Clin Genitourin Cancer 2023; 21:105.e1-105.e6. [PMID: 35948483 DOI: 10.1016/j.clgc.2022.07.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2021] [Revised: 07/05/2022] [Accepted: 07/09/2022] [Indexed: 02/03/2023]
Abstract
PURPOSE To evaluate the feasibility, tolerance and efficacy of cisplatin+capecitabine as a proposed combination in concurrent chemoradiotherapy for patients with muscle-invasive bladder cancer (MIBC). METHODS MIBC patients with stage T2-T4aN0M0 participated in this single-arm clinical trial. After maximal TURBT, 66Gy/33 daily fractions of radiation were administered with concurrent chemotherapy of cisplatin (35 mg/m2) and capecitabine (625 mg/m2). The primary endpoint was treatment tolerability, defined as receiving capecitabine+cisplatin combination for at least 5 weeks during radiation therapy. The secondary endpoints included complete response (CR) and acute toxicity rates. RESULTS This study included 19 MIBC patients from 2018 to 2019. Eighteen patients (94.7%, 95%CI: 75.4-99.0) completed the planned treatment course. Only one patient (5.26%, 95%CI: 0.9-24.6) discontinued the treatment due to grade-3 GI toxicity. Among those who completed the treatment, CR was seen in 12 patients (66.7%, 95% CI = 44.4-88.9) with no grade ≥ 3 toxicities. The most common grade-2 side effects during therapy were renal complications (57.9%), and the only grade-2 complication after therapy was urinary-related (11.1%). The median follow-up was 31 months and the median overall survival (OS) was 31 months. The 2-year OS was 78% (95% CI 58.4-97.6), Cystectomy-free survival was 61% (95% CI: 37.5-84.5), and the median OS after recurrence was 13 months. Distant metastases were the first type of recurrence in most patients with a recurrence, which occurred in 7 (36.8%) patients. Median metastasis-free survival (MFS) was 30 months, and 2-year MFS was 66% (95% CI:45-87). CONCLUSION The promising tolerability rate seen with concurrent cisplatin+capecitabine in this study was comparable to the available literature. Thus, this combination concurrently with radiation warrants further studies in the context of chemoradiotherapy of MIBC.

Abstract
OBJECTIVES Precise and quantitative assessment of the trend of cancer burden enables policymakers and health managers to prioritize diseases and allocate resources better. This infers what caused a decrease or increase in the rate of cancer occurrence, and if it denotes timing of implementation of a control measure, it presents the impact on the disease rate. This study's objective was to evaluate trends in child and adult cancer in Iraq from 2000 onwards. METHODS We used the registries of the Iraqi Ministry of Health that were gathered from all governorates from 2000-2016. Data were presented as incidence rates to depict the trends of different types of cancers distributed by age, gender, and governorates. RESULTS Breast cancer witnessed a significant increase with predominance in females. Lung cancer rate increased significantly from 4.08 to 5.60/100 000 (p = 0.038), affecting males more than females. The brain cancer trend showed a bimodal pattern (two peaks in 2004 and 2011) with no significant trend change (p = 0.788). Both genders were similarly affected. The trend of stomach and colorectal cancer showed an accelerated increase after 2007. CONCLUSIONS Almost all cancers (particularly lung and gastrointestinal) showed constantly raising trends, especially after 2007. Only cervical and laryngeal cancer had a decreasing trend. Most cancers were predominant in males.

Abstract
Background Brain cancer is a rare and deadly malignancy with a low survival rate. The present study aims to evaluate the epidemiology of brain cancer and its relationship with the human development index (HDI) worldwide. Methods This is an ecological study. The data on cancer incidence and cancer mortality was extracted from the World Bank for Cancer in 2018 (GLOBOCAN 2018). The incidence, mortality rate, and brain cancer distribution maps were drawn for different countries. We used correlation and regression tests to examine the association of incidence and mortality rates of brain cancer with HDI. The statistical analysis was carried out by Stata-14 and a significance level of 0.05 was considered. Results According to the results of Global Cancer Registry in 2018, there were 18,078,957 registered cases of cancer in both sexes, of which 29,681 were related to brain cancer. The highest incidence (102,260 cases, 34.4%) and mortality (77,815 cases, 32.3%) belonged to very high HDI regions. Results showed that incidence (r = 0.690, P < 0.0001) and mortality rates (r = 0.629, P < 0.001) of brain cancer are significantly correlated with HDI. We also observed a positive correlation between brain cancer incidence and Gross National Income (GNI) (r = 0.346, P < 0.001), Mean Years of Schooling (MYS) (r = 0.64, P < 0.001), TABLE (LEB) (r = 0.66, P < 0.001) and Expected Years of Schooling (EYS) (r = 0.667, P < 0.001). Results also revealed that mortality rate was significantly correlated with GNI (r = 0.28, P < 0.01), MYS (r = 0.591, P < 0.01), LEB (r = 0.624, P < 0.01), and EYS (r = 0.605, P < 0.01). Conclusion The results of the study showed that the incidence and mortality of brain cancer in countries with higher HDI levels is higher than countries with lower HDI levels, so attention to risk factors and action to reduce it in countries with higher HDI levels in controlling this cancer in this Countries are effective.

Abstract
Background and objectives: Type 2 diabetes mellitus (T2DM) is becoming increasingly prevalent worldwide and is associated with increased incidence of kidney cancer and bladder cancer (BC). However, studies have produced conflicting results. Therefore, we retrospectively evaluated the incidence of BC in T2DM patients using the Taiwan National Health Insurance Research Database (NHIRD). Materials and Methods: We included 31,932 patients with a diagnosis of T2DM in the study group and 63,864 age- and sex-matched patients without T2DM at a ratio of 1:2 in the control group. The primary outcome was the diagnosis of BC. Cox proportional hazards regression was used to evaluate the incidence and adjusted hazard ratio (aHR) of BC in the multivariate model. Results: After a 16-year follow-up, we found that 67 BC cases occurred in the study group and 152 BC events in the non-T2DM group without a significantly higher risk (aHR: 0.842, 95% confidence interval: 0.627–1.13). Conclusions: T2DM patients do not have a higher risk of BC.

Abstract
Background Bladder cancer (BC) is the sixth common cancer among Iranians. Various risk factors such as smoking, body mass index, chronic infection, age, and genetic factors are associated with BC progression. Methods It has been shown that a significant ratio of patients have tumors with muscle bladder layer invasion and poor prognosis at the time of diagnosis. Therefore, the early detection of tumors is required to reduce the mortality rate of BC cases. Since there is a wide geographical incidence variation in BC in Iran, it seems that the ethnic and genetic factors can be the main risk factors among Iranian BC patients. Results For the first time, in present review we have summarized all of the reported genes among Iranian BC patients until now which were significantly associated with tumorigenesis. Moreover, we categorized all of the reported genes based on their cell and molecular functions to clarify the genetic and molecular biology of BC among Iranian population. Conclusion This review paves the way of determination of a population‐based genetic panel markers for the early detection of BC in this population.

Abstract
Cancer is a public health problem worldwide. Taiwan has a higher incidence rate of urological cancers than many Asian countries do. Aristolochic acid has been considered a potent carcinogen. In this study, we examined whether the cessation of the sales and preparation of aristolochic acid-containing Chinese herbal products (AA-CHPs) in Taiwan contributed to a decline in the incidence rates of bladder cancer, carcinomas of the renal pelvis and other urinary organs, and kidney cancer. We conducted an interrupted time-series analysis of long-term trends in the incidence rates of the aforementioned cancers between 1995 and 2013 in Taiwan. The incidence rates of bladder cancer and carcinomas of the renal pelvis and other urinary organs decreased considerably after 2008 and 2011, respectively. Notably, these change-of-slope time points occurred after the year 2003, when a ban on AA-CHPs was imposed in Taiwan. The ban on AA-CHPs in Taiwan was possibly associated with the reduction in the incidence of bladder cancer and carcinomas of the renal pelvis and other urinary organs.

Abstract
BACKGROUND Bladder cancer is the ninth most common cancer in the world. OBJECTIVES This study aimed to determine the correlation between age-standardized incidence rates of bladder cancer and some risk factors in Asian countries through an extensive ecological analysis. METHODS This ecological study evaluated the correlation between age-standardized incidence rates of bladder cancer and obesity, overweight, physical inactivity, and tobacco use in 30 Asian countries. To determine the factors that were significantly related to age-standardized incidence rate of bladder cancer, a univariate analysis was performed using simple linear regression. In the next step, variables with p-values less than 0.25 were entered into a multivariate linear regression model. RESULTS The incidence of bladder cancer was higher in countries with higher prevalence of overweight (r2 = 0.36, p < 0.001), obesity (r2 = 0.34, p = 0.001), current daily tobacco use (r2 = 0.17, p = 0.03), and physical inactivity (r2 = 0.13, p = 0.04). The results of multiple regression analysis indicated a direct correlation between the incidence of bladder cancer and overweight (β = 0.15, p < 0.001) and current daily tobacco use (β = 0.21, p = 0.001). CONCLUSIONS There was a significant relationship between the incidence of bladder cancer and overweight and current daily tobacco use. Further epidemiological studies are needed to confirm this relationship.

Abstract
Purpose: Various aspects of diet have been implicated to play a role in the etiology of bladder cancer. Studies examining this association have been conducted primarily in Western countries but none in Middle Eastern Countries. Method: We examined the association between the dietary inflammatory index (DII®) and bladder cancer in an Iranian case-control study. A total of 56 incident cases with a mean age of 60 years and 109 controls with a mean age of 57 years, attending the same hospital as the cases during the same time period, were recruited. The DII is a literature-derived index developed to determine the inflammatory potential of diet and was computed using a validated food frequency questionnaire. Logistic regression was used to estimate odds ratios, with DII fit as continuous and as a dichotomous variable. Results: Multivariate analyses revealed that subjects with higher DII score (>-0.12) are at higher risk of bladder cancer [odds ratio (OR) = 2.46; 95% CI = 1.12-5.41, P value = 0.02)] compared to subjects with lower DII scores (≤-0.12). Stratified results showed stronger association was among current/ex-smokers (ORDII (>-0.12/≤-0.12) = 3.30; 95% CI = 1.07-10.16). Conclusion: These data suggest a pro-inflammatory diet may be a risk factor for bladder cancer among Iranians.

Abstract
In Iran, a developing country in southwest Asia, an epidemiologic transition is underway from communicable to noncommunicable diseases. In Iran, cancer is the second largest group of chronic non-communicable diseases (NCDs) and the third most common cause of death following heart disease, accidents and other natural phenomena. There are some studies reporting an increasing trend in the incidence and mortality rate of a variety of cancers in Iran. Therefore, controlling and preventive interventions pertaining to cancers must be a main priority for health policy and it is recommended that the high-risk population receive earlier screening. In this review, incidence and mortality of colorectal, lung, liver, thyroid, and bladder cancers in Iran are reported.

Abstract
BACKGROUND Transitional cell carcinoma (TCC) accounts for around 95% of bladder cancers and is the 4th most common cancer among men and the tenth most common in women, in the US. There is a constant need to clarify current TCC incidence and mortality rates among different population groups for better clinical practice guidelines. We aimed to describe the TCC incidence and incidence-based mortality by demographic and tumor-related characteristics over the last 40 years in the US. METHODS We obtained data from the SEER 18 registries to study TCC cases that were diagnosed between the years 1973 and 2014. We calculated incidence rates and incidence-based mortality rates in different demographic and tumor-related characteristics and expressed rates by 100,000 person-years. We then calculated the annual changes in incidence and incidence-based mortality rates and displayed them as annual percent changes (APCs). RESULTS There were 182,114 patients with TCC between 1973 and 2014 in the United States. Overall incidence rates of TCC increased 0.16% (95% CI, 0.02-0.30, p = .02) per year over the study period. However, the incidence declined significantly since 2007; (95%CI,-1.89- -0.77, p < .001), except among the elderly and African Americans, which increased significantly over the study period. Overall TCC mortality rates did not change over the study period. However, since 2000 it started to decrease significantly. CONCLUSION TCC incidence and incidence-based mortality rates had been showing significant increases over the previous decades. However, significant declines in both incidence and incidence-based mortality rates have been observed over the recent years, except in some patients with certain racial groups. Improved understanding of the etiological and ecological factors of TCC could lead to further declines in incidence and incidence-based mortality rates.

Abstract
Nowadays, urinary bladder cancer represents a major health problem, due to very high medical and social costs. This disease affects mainly the elderly. We performed a study on 1073 patients admitted to the Urology Clinic within the Emergency Clinical Hospital of Craiova, between 2013-2015 with bladder cancer. Of the 1073 cases, 741(69.06%) were diagnosed in men, and 332 (30.94%) were found in women, the men/ women ratio being of 2.23/1. The highest incidence of bladder tumors was recorded in individuals aged between 60 and 79 years old. In this age group, there were admitted 734 patients with bladder cancer, representing 68.44%. Regarding the tumor recurrence, out of 1073 bladder tumors, a number of 608 (56.66%) patients were diagnosed with primary tumors, while a number of 465 (43.34%) patients presented recurrent tumors. Of the symptoms presented by the patients, the most frequent were haematuria (present in about 87% of the patients), pollakiuria (present in 64% of the patients), dysuria (present in 55% of the patients) and urinary infections (present in about 23% of the patients).

Abstract
Objective To analyze the correlation between municipal human development indices (MHDIs) and stroke mortality in residents of Brazilian state capitals in 2010. A secondary data analysis was conducted in 2015 using data for the MHDI and the following dimensions: income, longevity and education which were obtained from the United Nations Development Program. Additionally, we analyzed age-standardized stroke mortality data from the Department of System Information Unified Health of Brazil. Results We observed a correlation between stroke mortality and MHDIs overall (Pearson r = − 0.563; p = 0.002) and within the following dimensions: income (Spearman’s ρ = − 0.479; p = 0.011), longevity (Pearson r = − 0.510; p = 0.006) and education (Pearson r = − 0.592; p = 0.001). We identified moderate but significant negative correlations between MHDI overall and in its individual dimensions (income, longevity, and age) and stroke mortality in Brazilian capitals. Stroke is the second leading cause of death in industrialized countries and the leading cause of death in Brazil. Therefore, the discovery of factors that may influence the epidemiology of stroke is important for the construction of adequate policies considering to the socioeconomic status in these places and with an emphasis in lower socioeconomic status places.

Abstract
Introduction: The epidemiology of common cancers in Kerman province, southeast of Iran, was assessed based upon results of the Kerman Population-Based Cancer Registry Program (KPBCR). Methods: in this retrospective study, all patients diagnosed with primary cancers and registered with the KPBCR were included. New cancer cases registered from 2014 were identified from pathological labs, medical reports of 48 health facilities providing cancer diagnosis or treatment services and the national death registry program. Data for patients who were referred to neighboring provinces to access health services were also collected from national referral registries. Results from autopsies was additionally extracted from regional forensic and legal medicine centers and added to the registry periodically. Age standardized incidence rates (ASRs) per 100,000 person-years for all cancers were computed, using direct-standardization and CanReg methodology. Mortality to incidence (M:I) ratios and microscopically verified (MV) proportions were calculated as quality measures. Results: A total of 2,838 cases of cancer were registered in Kerman province, 2014. Of these 45. 6% involved women (n=1,293). Individuals aged 60-64 years represented the largest proportion (11.6%) of the total cancer prevalence, followed by those aged 55-59 years (10.86%) and 65-69 years (8.99%). The ASRs for all cancers were 155.1 and 118.90 per 100,000, in men and women, respectively. In women, breast (ASR: 26.4), skin (ASR: 13.0), thyroid (ASR: 9.2), leukemia (ASR: 8.0) and colorectal (ASR: 7.70) were the most common cancers. In men, bladder (ASR: 24.70), skin (ASR: 16.80), lung (ASR: 14.6), leukemia (ASR: 14.50), and stomach (ASR: 10.8) were found to be the most frequent. Conclusion: This study provided latest evidence on epidemiology of cancer in the southeast of Iran that could be used to empower prevention and control interventions in a developing country.

Abstract
OBJECTIVES To clarify period prevalence (PP), incidence rate (Ir), and reported mortality for patients with bladder cancer (BC) in Isfahan Province/Iran, as BC is the most common cancer of the urinary tract in Iran and other parts of the world. PATIENTS AND METHODS Data from 21 March 2011 to 3 March 2015 was obtained from the Isfahan Cancer Registry. BC was distinguished by the related established topography code (C67). Ir and PP were calculated and expressed per 100 000 persons. RESULTS In all, 279 females and 1376 males were identified. For the total population the PP was calculated as 33.2. This value corresponded to a PP of 54.4 for males and 11.4 for females (P < 0.001). Histologically, 63% of patients had invasive BC. Irs versus mortality rates were calculated for each year, i.e. 2011-2012, 2012-2013, 2013-2014, and 2014-2015, as 7.7 vs 0.56, 8.1 vs 0.74, 7.4 vs 0.98, and 9.9 vs 0.84, respectively. The mean (SD, range) age of the patients was 65.2 (13.9, 3-100) years. In relation to the age of the study population, BC occurred in 12% of patients aged <50 years and in 15% of those aged ≥80 years. CONCLUSION The PP for BC in the male population was 4.8-times higher than females. There was a 28.6% increase in the Ir over the study period. Further study concerning environmental exposure, genetic factors, job-related exposure to various chemical carcinogens, and geographical distribution in Isfahan and its' rural provinces would seem to be valuable.

Abstract
OBJECTIVES Pancreatic cancer has a lower morbidity yet higher case fatality rates (CFRs) compared with other gastrointestinal cancers. The effects of socio-economic components on pancreatic cancer rates have been acknowledged; however, the effects of the Human Development Index (HDI) inequality are not. In this study, we aimed to determine the contribution of important socio-economic components on pancreatic cancer rates using a decomposition approach. STUDY DESIGN Global ecological study. METHODS Incidence and mortality rates of pancreatic cancer were obtained for 172 countries from GLOBOCAN and the United Nations Development Program. The World Bank database was also used to obtain the HDI and its gradient for 169 countries. Inequality in pancreatic cancer age-specific incidence and mortality rates was calculated according to the HDI using the concentration index (CI). We decomposed the CI to determine main contributors of the inequality. RESULTS The CI for incidence and mortality of pancreatic cancer in both genders according to the HDI was 0.26 (95% confidence interval: 0.21-0.30) and 0.25 (95% confidence interval: 0.21-0.30), respectively, which indicated more concentrated inequality in advantaged countries. About 80% of the inequality sources were predicted by socio-economic component in both rates of pancreatic cancer. The main contributors to inequality were the mean years of schooling, life expectancy at birth, expected years of schooling, and urbanization. CONCLUSION Global inequalities exist in pancreatic cancer incidence and mortality rates according to the HDI; in addition, inequality was more concentrated in countries with higher score of HDI.

Abstract
Citrus unshiu peel has been used to prevent and treat various diseases in traditional East-Asian medicine including in Korea. Extracts of C. unshiu peel are known to have various pharmacological effects including antioxidant, anti-inflammatory, and antibacterial properties. Although the possibility of their anti-cancer activity has recently been reported, the exact mechanisms in human cancer cells have not been sufficiently studied. In this study, the inhibitory effect of ethanol extract of C. unshiu peel (EECU) on the growth of human bladder cancer T24 cells was evaluated and the underlying mechanism was investigated. The present study demonstrated that the suppression of T24 cell viability by EECU is associated with apoptosis induction. EECU-induced apoptosis was found to correlate with an activation of caspase-8, -9, and -3 in concomitance with a decrease in the expression of the inhibitor of apoptosis family of proteins and an increase in the Bax:Bcl-2 ratio accompanied by the proteolytic degradation of poly(ADP-ribose) polymerase. EECU also increased the generation of reactive oxygen species (ROS), collapse of mitochondrial membrane potential, and cytochrome c release to the cytosol, along with a truncation of Bid. In addition, EECU inactivated phosphatidylinositol 3-kinase (PI3K) as well as Akt, a downstream molecular target of PI3K, and LY294002, a specific PI3K inhibitor significantly enhanced EECU-induced apoptosis and cell viability reduction. However, N-acetyl cysteine, a general ROS scavenger, completely reversed the EECU-induced dephosphorylation of PI3K and Akt, as well as cell apoptosis. Taken together, these findings suggest that EECU inhibits T24 cell proliferation by activating intrinsic and extrinsic apoptosis pathways through a ROS-mediated inactivation of the PI3K/Akt pathway.

Abstract
Background The incidence and mortality of kidney cancer have steadily increased by 2%- 3% per decade worldwide, and an increased risk of kidney cancer has been observed in many Asian countries. The information on the incidence and mortality of a disease and its distribution is essential for better planning for prevention and further studies.
Objectives This study aimed to assess the incidence and mortality of kidney cancer and their correlation with the human development index (HDI) in Asia.
Materials and Methods This ecological study was based on GLOBOCAN data Asia for assessment the correlation between age-specific incidence rate (ASIR) and age-specific mortality rate (ASMR) with HDI and its details that include life expectancy at birth, mean years of schooling and gross national income (GNI) per capita. We use of correlation bivariate method for assessment the correlation between ASIR and ASMR with HDI and its components.
Results A total of 121 099 kidney cancer cases were recorded in Asian countries in 2012.Overall, 80 080 cases (66.12%) were males. Sex ratio was 1.95. The three countries with the highest number of new patients were china (66 466 cases), Japan (16 830 cases), India(9658 cases), respectively. Positive correlation were seen between HDI and ASIR of kidney cancer 0.655 (P = 0.001), and HDI and ASMR of kidney cancer 0.285 (P = 0.055).
Conclusions A positive relationship between ASIR and the HDI was seen. The relationship is due to risk factors in countries with high development such as older age, smoking, hypertension, obesity, and diet. However, ASMR showed no significant relationship with HDI.

Abstract
Background The aim of this study was to evaluate the incidence and mortality of prostate cancer and their relationship with the Human Development Index (HDI) and its components in Asia in 2012. Methods This study was an ecological study conducted based on the GLOBOCAN project of the World Health Organization. The correlation between standardized incidence rate (SIR) and standardized mortality rate (SMR) of prostate cancer with HDI and its components was assessed using SPSS Inc Version 18.0 (Chicago). Results There were 1,094,916 incident cases of prostate cancer and 307,481 deaths recorded in 2012 worldwide. SIR and SMR due to HDI were 72 and 9.7 in very high human development regions, 37.5 and 12.9 in high human development regions, 7 and 3.7 in medium human development regions, and 14.9 and 12.1 in low human development regions per 100,000 people, respectively. A positive correlation of 0.475 was seen between SIR of prostate cancer and HDI (P ≤ 0.001). Also, a negative correlation of 0.160 was seen between SMR of prostate cancer and HDI (P = 0.032). Conclusion The incidence of prostate cancer is high in countries with higher development. A positive correlation was observed between the SIR of prostate cancer and the HDI and its components, such as life expectancy at birth, mean years of schooling, and the gross national income per capita. In addition, there was a negative correlation between SMR and HDI.

Abstract
BACKGROUND The highest incidence of lung cancer is seen in North America and the lowest incidence in central Africa. Socioeconomic factors of inequality reflect regional disparities in human development. Due to the importance of awareness about incidence and mortality of lung cancer in health programming and the possible role of the human development index (HDI), this study was done with the aim to investigate the epidemiology of lung cancer in the world and its relationship with HDI. METHODS The study was conducted based on data from the world data of cancer and the World Bank (including the HDI and its components). Data about the age-specific incidence and mortality rate (ASR) for every country in 2012 were getting from the global cancer project. To analyze data, correlation tests between incidence and death rates, and HDI and its components were employed with a significance level of 0.05 using SPSS software. RESULTS Lung cancer with standardized incidence rate (ASIR) and standardized mortality rate (ASMR), equal to 23.1 and 19.7 (in 100,000 people), respectively. The highest and lowest values of mortality incidence ratio (MIR) for lung cancer due to continents division were 0.93 and 0.71 for Eastern Africa and Australia/New Zealand, respectively. Univariate analysis showed significant relationship (P<0.0001) between ASIR and ASMR with life expectancy at birth and mean years of schooling. CONCLUSIONS The highest MIR for lung cancer was for medium human development countries. Linear regression analysis showed a reverse significant relationship between MIR and HDI.
