ABSTRACTObjective: Gastric cancer is the fifth most common cancer and the third cause of death from cancers in the world and is known as the most deadlycancer in Iran. Since the knowledge about the epidemiological situation and the trend of incidence of this cancer is essential to plan for the preventionand treatment of cancer, this study was performed with the aim of investigating the epidemiological status, the rate and the trend of gastric cancerincidence in Sistan and Baluchestan province.Methods: This study was conducted using existing data and data extracted from the National Cancer Registry System and the Disease ManagementCenter of Iranian Ministry of Health between 2003 and 2008. Age-Standardized incidence rates (ASIR) were calculated using the world standardpopulation. The crude incidence rate was also computed. Cochran–Armitage test for linear trend was used for evaluation of the incidence trend.Results: The number of 255 cases of gastric cancer occurred in the study period that 188 cases were in men and 67 in women. Accordingly, theincidence of gastric cancer has had an ascending trend in Sistan and Baluchestan (p=0.00) and its incidence in men and women has changed to1.18 and 2.73 in 2004 to 1.84 and 4.48 in 2008, respectively. Furthermore, with ageing, the incidence of gastric cancer has increased in both sexes andits incidence was higher in men than women.Conclusion: The incidence of gastric cancer has an increasing trend in Sistan and Baluchestan, hence, etiological surveys and programs of earlydiagnosis are useful in this province to the reduce cancer.Keywords: Incidence, Gastric cancer, Iran, Epidemiology.

Background: Nasopharyngeal carcinoma (NPC) is the fifth most common cancer among Malaysians. While several studies have reported the trend of NPC in other states in Malaysia, no studies have reported the trend of NPC in Pahang state. This study was designed to report the number and distribution of newly diagnosed NPC cases in Pahang. Methods: NPC cases that were diagnosed between 2012 and 2017 in two referral hospitals in Pahang were traced. The crude incidence rate (CR) and age-standardised rate (ASR) were calculated to investigate the NPC incidence. Results: There were 143 new cases of NPC reported from the two hospitals. The mean age at diagnosis was 52.0 ± 13.7 years old. The majority of cases involved males (74.1%) with a male to female ratio of 2.9:1. Chinese males were found to have the highest incidence with a mean ASR of 4.7 per 100,000 population. Overall, the mean ASR for Pahang was 2.4 per 100,000 population for males and 0.9 per 100,000 population for females. Conclusion: The total number of NPC cases reveals an increasing trend from 2012 to 2014 and then a slightly decreasing trend from 2015 to 2017. The incidence of NPC in Pahang was intermediate in males and low in females.

Background and Objectives: Lung cancer (LC) is the most common cancer in the world. Developing countries in the Middle East and North Africa (MENA) region, including Lebanon, have witnessed a great increase in the incidence rates of this disease. The aim of our study is to investigate the incidence rates of lung cancer in Lebanon from 2005 to 2015 and to compare these rates to other countries from the MENA region and other regions of the world. Material and Methods: Lung cancer data for the years 2005–2015 were collected from the National Cancer Registry of Lebanon and stratified by gender and age group. Age-specific and age-standardized incidence rates were calculated and analyzed using joinpoint regression. Age-standardized incidence rates to the world population (ASR(w)) for other countries were obtained from two online databases. Results: Lung cancer ranked as the second most common cancer in Lebanon and accounted for 9.2% of all newly diagnosed cancers. Lung cancer ASR(w) showed a significantly increasing trend over the period studied for males and females. Lung cancer ASR(w) among males in Lebanon came second after Malta when compared to other MENA countries, but it was among the lowest when compared to non-MENA countries. For females, Lebanon ranked first when compared to other MENA countries but was among the lowest when compared to countries in other regions of the world. The lung cancer incidence rate increased with age in both sexes and 89.2% of patients were 50 years of age or older. Conclusion: Lebanon has the highest incidence of LC in females and the second highest for males in the MENA region. The lung cancer incidence rate is on the rise and older age groups are much more burdened by this disease than the young ones. Several risk factors, particularly smoking, play a role in increased LC incidence among the Lebanese population.

Objective.To calculate the incidence rates of osteoarthritis (OA) and to describe the changes in incidence using 18 years of administrative health records.Methods.We analyzed visits to health professionals and hospital admission records in a random sample (n = 640,000) from British Columbia, Canada, from 1991/1992 through 2008/2009. OA was defined in 2 ways: (1) at least 1 physician diagnosis or 1 hospital admission; and (2) at least 2 physician diagnoses in 2 years or 1 hospital admission. Crude and age-standardized rates were calculated, and the annual relative changes were estimated from the Poisson regression models.Results.In 2008/2009, the overall crude incidence rate (95% CI) of OA using definition 1 was 14.6 (14.0–14.8); [12.5 (12.0–13.0) among men and 16.3 (15.8–16.8) among women] per 1000 person-years. The rates were lower by about 44% under definition 2. For the period 2000/2001–2008/2009, crude incidence rates based on definition 1 varied from 11.8 to 14.2 per 1000 person-years for men, and from 15.7 to 18.5 for women. Annually, on average, crude rates rose by about 2.5–3.3% for both men and women. The age-adjusted rates increased by 0.6–0.8% among men and showed no trend among women.Conclusion.Our study generated updated incidence rates of administrative OA for the Province of British Columbia. Physician-diagnosed overall incidence rates of OA varied with the case definitions used; however, trends were similar in both case definitions. Age-adjusted rates among men increased slightly during the period 2000/2001–2008/2009. These findings have implications for projecting future prevalence and costs of OA.

Analysis of the demographic, temporal and seasonal distribution of hantavirus infections in Barbados was conducted using national surveillance data for 861 laboratory confirmed cases during 2008-2016. The crude incidence rate of hantavirus infections varied from 5.05 to 100.16 per 100,000 persons per year. One major hantavirus epidemic occurred in Barbados during 2010. Hantavirus cases occurred throughout the year with low level transmission during the dry season (December to June) with increased transmission during rainy season (July to November) and a seasonal peak in August. Hantavirus incidence rates were significantly higher in females than males every year during the study period. More than 50% of hantavirus cases were 30 years of age or less. The highest incidence rate (63.36 cases per 100,000 population) was observed among patients 0–4 years of age. This represents the first epidemiological data for hantavirus disease among an entire population in the English-speaking Caribbean.

Abstract Introduction Gastric cancer is a major health burden worldwide. Based on GLOBOCAN 2018 data, stomach cancer is the fifth most common neoplasm and the third most deadly cancer, with an estimated 783,000 deaths in 2018. Unfortunately, only a few countries have set up extensive programs of early screening. In Tunisia the gastric cancer ranks among the ten most frequent cancers with more than 637 new cases per year. The aim of this study was to we report trends in the gastric cancer incidence during the span of time between 2002 and 2013 from the population-based cancer registry of the centre of Tunisia, and to predict the future number of cancer cases by 2030. Methods The cancer incidence data were collected from the cancer register of the Tunisian Center from 2003 to 2012.The data were stratified by cancer site, sex and age. We used SPSS software in order to calculate the crude incidence rates and standardized incidence rates. SPSS software was used in order to estimate the future number of cancer cases by 2030. Results During our study period, 326 cases of gastric cancer were observed. 53.1% of our patients were male with a sex ratio male to female 1.13.The crude incidence rates were 5.71 for male patients and 5.43 for females. The standardized incidence rates were 7.22 and 6.3 respectively for male and female patients. A stable trend was observed. Only 28 cases of gastric cancer are predicted by 2030. Conclusions Over the recent, there has been a slight decrease in gastric cancer rates. Many preventive steps should be encouraged in order to maintain this decreasing trend such as changing dietary habits by encouraging the consumption of fresh fruit and vegetables, as well as decreasing the use of tobacco and salt. Key messages Gastric cancer is a major health burden worldwide, only a few countries have set up extensive programs of early screening. Changingdietary habits by encouraging the consumption of fresh fruit and vegetables, as well as decreasing the use of tobacco and salt.

Abstract Background Age-standardization is common for adjustment of unequal population in different ages as it can influence cancer incidence. However, for planning healthcare services (including screening), one needs absolute magnitude since everyone needs intervention. This study assessed the effect of age-standardization on understanding the global differentials in magnitude of oral cancer. Methods Data on cancer incidence rates of oral cancers for 2008-2012, was obtained from the website of international agency for research on cancer for all 334 population-based cancer registries. Scatter plots were prepared between age-standardized and crude incidence rates to assess the ratio between them according to proportion of old people for all countries. Areas with high occurrence of oral cancer were identified. Results The ratio between age-standardized and crude incidence rate was >1 in countries with high proportion of older population (high-development-index countries), indicating an artificial widening of gap between incidence rates between countries due to age-standardization. Six areas had higher crude incidence rate among men than India. Based on the published estimates, the per-unit-population burden in Europe was 6.3% higher than India, while in USA it was merely 12.5% lower than India. Conclusions The perception of low burden of oral cancer in high-economy countries is artificial, brought about by common practice of age-standardization. Key messages Organization of oral cancer screening activities by countries with resources and expertise will provide much needed knowledge on its natural history and efficacy of control strategies.

Introduction. Sustainable development of territories affected by the Chernobyl disaster, require a number of managerial decisions, to reduce the level of radiophobia and psycho-emotional stress in society. Aim. To study the relationship between the indicators of the incidence of hemoblastosis with the density of contamination of territories with radioactive elements. Material and methods. An ecological population epidemiological study based on the calculation of the correlation coefficients of the incidence rates of hemoblastosis with the density of radioactive contamination. Results. There is no connection between the incidence of hemoblastosis and the density of radioactive contamination of territories. A statistically significant risk of multiple myeloma is observed in areas with a 137Cs contamination density of 1.0-4.99 Ci/km2. There was a statistically significant strong (r> 0.95) correlation between the crude incidence rate and standardized by age, sex and place of residence incidence ratio. The presence of strong correlations between these indicators give the possibility to use crude incidence rate instead of SIR in the analysis of morbidity by rayons. Conclusions. No correlation was found between the incidence of hemoblastosis and the density of radioactive contamination.

Introduction/Objective. The incidence of both melanoma and non-melanoma skin cancers (NMSC) has been increasing over the past decades worldwide. NMSC is the most common cancer in white population and melanoma is one of the deadliest cancers today. The objective of the paper was to determine trends in age-standardized incidence rates of NMSC and melanoma in central Serbia from 1999 to 2013. Method. A descriptive epidemiological study was done. Data about incidence for NMSC and melanoma were obtained from the Serbian Cancer Registry and data about population originating from 1991, 2001, and 2011 censuses. Crude incidence rates were calculated per 100,000 inhabitants. Direct method of standardization was performed with the world population as the standard. Trend lines were estimated using linear regression. Results. During a 15-year period, the total number of new NMSC cases was 41,719 [21,690 (52%) in men and 20,029 (48%) in women]. There were 5,781 new cases of melanoma [2,969 (51.4%) in men and 2,812 (48.6%) in women]. A significantly increasing incidence trend for NMSC both in men (y = 0.617x + 24.29, R2 = 0.500) and women (y = 0.672x + 0.670, R2 = 0.670) was determined. In the same period, a statistically significant increase of incidence trend for melanoma was determined in men (y = 0.111x + 3.708, R2 = 0.384) and in women (y = 0.098x + 3.375, R2 = 0.409). NMSC was registered in persons of all ages. NMSC incidence increased rapidly in persons older than 50 years. Melanoma predominates in children and adolescents and is registered more frequently than NMSC in persons bellow 60 years of age. Conclusion. Our findings showed significantly increasing trend of age-standardized incidence rates for both NMCC and melanoma. In the observed period, there were 7.2 times more new cases of NMSC than melanoma in the population of central Serbia. There were more registered new cases of NMSC and melanoma in men than in women. Screening of skin cancers and earlier diagnosis may improve treatment and prognosis.

Object The incidence of subarachnoid hemorrhage (SAH) in Japan has been reported to be among the highest in the world. The aim of this study was to analyze the incidence of SAH and its trends in Akita Prefecture, Japan. Methods The incidence rate of SAH between January 1, 1989, and December 31, 1998, was investigated using the prospective Akita Stroke Register. Computed tomography scans were obtained in all suspected cases of SAH. During the study period, 3257 patients with their first SAH were registered. The crude annual incidence rates of SAH in men, women, and both sexes were 20, 33, and 27 per 100,000 population per year, respectively. Age-standardized incidence rates remained stable. Crude incidence rates in women increased. In men the incidence reached a plateau after 55 years of age; in women it peaked in the eighth decade of life. The 28-day case fatality rate was 26.7%, without significant changes. Two diurnal peaks were observed: one at 7 a.m. and another at 5 p.m. The incidence was lowest in summer and highest in spring, in both sexes. Conclusions The incidence of SAH in patients in Akita Prefecture is similar to that reported in other Japanese studies. The age-standardized incidence rates are stable. The increasing crude incidence in women is probably attributable to the aging of the Japanese population.

Background. The Argentia region of Newfoundland and Labrador, Canada, was home to a US naval base during a 40-year period between the 1940s and the 1990s. Activities on the base resulted in contamination of the soil and groundwater in the region with chemicals such as heavy metals and dioxins, and residents have expressed concern about higher rates of cancer in their community. This study investigated the rate of cancer diagnosis that is disproportionately high in the Argentia region.Methods. Cases of cancer diagnosed between 1985 and 2011 were obtained for the Argentia region, two comparison communities, and the province of Newfoundland and Labrador. Crude and age-standardized incidence rates of cancer diagnosis were calculated and compared. The crude incidence rate was adjusted for differences in age demographics using census data, and age-standardized incidence rates were compared.Results. Although the Argentia region had a higher crude rate of cancer diagnosis, the age-standardized incidence rate did not differ significantly from the comparison communities or the provincial average. Argentia has an aging population, which may have influenced the perception of increased cancer diagnosis in the community.Conclusions. We did not detect an increased burden of cancer in the Argentia region.
