Background: Cancer is a non-communicable disease that is considered deadly in many cases. In recent years, the mortality rates from breast cancer have increased with increasing incidences. The present study was conducted to determine five year survival of women with breast cancer in Yazd, in the central region of Iran. Materials and Methods: In a prospective study, data were obtained from the patient's medical records with breast cancer that were referred to the Shahid Sadoughi hospital and radiotherapy center from 2002-2007 and followed up for 5 years. The data collected were analyzed by SPSS/16 and Kaplan-Meyer test and log-rank test and Cox proportional hazard model was used. Results: The mean age of breast cancer diagnosis was $48.3{\pm}11.7$ years. The 1-, 2-, 3-, 4- and 5-year cumulative survivals for breast cancer patients were 95%, 86%, 82%, 76% and 70%, respectively. There were significant differences with age distribution (p=0.006). A significant decrease in the 5-year survival in patients with involvement of lymph nodes was lso observed. Conclusions: Education for early diagnosis in women must be considered and these findings support the need for breast cancer screening programs.

To study the full health effects of parental radiation exposure on the children of the atomic bomb survivors, the Radiation Effects Research Foundation developed a cohort of 76,814 children born to atomic bomb survivors (F1 generation) to assess cancer incidence and mortality from common adult diseases. In analyzing radiation-associated health information, it is important to be able to adjust for sociodemographic and lifestyle variations that may affect health. In order to gain this and other background information on the F1 cohort and to determine willingness to participate in a related clinical study, the F1 Mail Survey Questionnaire was designed with questions corresponding to relevant health, sociodemographic, and lifestyle indicators. Between the years 2000 and 2006, the survey was sent to a subset of the F1 Mortality Cohort. A total of 16,183 surveys were completed and returned: 10,980 surveys from Hiroshima residents and 5,203 from Nagasaki residents. The response rate was 65.6%, varying somewhat across parental exposure category, city, gender, and year of birth. Differences in health and lifestyle were noted in several variables on comparison across city and gender. No major differences in health, lifestyle, sociodemographics, or disease were seen across parental exposure categories, though statistically significant tests for heterogeneity and linear trend revealed some possible changes with dose. The data described herein provide a foundation for studies in the future.

Background: According to increase in elderly populations, and change in lifestyle and cancer-causing behavior, the global burden of cancer is increasing. For prevention and control of disease, knowledge of population statistics of cancers and their trends is essential. This study aimed to investigate the epidemiology and trends of cancer in the province of Kerman: southeast of Iran. Materials and Methods: This analytical and cross-sectional study was carried out based on cancer registry data at the Disease Management Center of the Health Ministry from 2004 to 2009 in the province of Kerman in Iran. Common cancers were defined as the number of reported cases and standardized incidence rates. To compute the annual percentage change (APC), joinpoint 4.1.1.1 software was applied. Results: Of 10,595 registered cases, 45.3% (4802 cases) were in women and 56.7% (5,793 cases) occurred in men. The standardized incidence rates for both females and males were increasing during the six years studied. The most common cancers in both sexes during six years of studied were skin (13.4%), breast (9.35%), bladder (7.8%), stomach (7.45%), leukemia (7.05%), colorectal(5.57%), lung(4.92%), trachea(3.51%) and prostate(2.48%). Conclusions: Our findings revealed that the cancer incidence is demonstrating increasing trends in both sexes in the province of Kerman. This may be because of changes in lifestyle, increasing exposure to risk factors for cancer and increase of life expectancy. If this is the case, increasing public awareness of cancer risk factors is a high priority, together with introduction of large-scale screening techniques.

Geographic information system (GIS) technology has useful applications for epidemiology, enabling the detection of spatial patterns of disease dispersion and locating geographic areas at increased risk. In this study, we applied GIS technology to characterize the spatial pattern of mortality due to liver cancer in the autonomous region of Guangxi Zhuang in southwest China. A database with liver cancer mortality data for 1971-1973, 1990-1992, and 2004-2005, including geographic locations and climate conditions, was constructed, and the appropriate associations were investigated. It was found that the regions with the highest mortality rates were central Guangxi with Guigang City at the center, and southwest Guangxi centered in Fusui County. Regions with the lowest mortality rates were eastern Guangxi with Pingnan County at the center, and northern Guangxi centered in Sanjiang and Rongshui counties. Regarding climate conditions, in the 1990s the mortality rate of liver cancer positively correlated with average temperature and average minimum temperature, and negatively correlated with average precipitation. In 2004 through 2005, mortality due to liver cancer positively correlated with the average minimum temperature. Regions of high mortality had lower average humidity and higher average barometric pressure than did regions of low mortality. Our results provide information to benefit development of a regional liver cancer prevention program in Guangxi, and provide important information and a reference for exploring causes of liver cancer.

Epidemiologic studies of Kawasaki disease (KD) have shown a new pattern or change of its occurrence suggestive of its pathophysiology or risk factors from the first patient with KD reported in 1961. The incidence of KD in Northeast Asian countries including Japan, South Korea, China, and Taiwan is 10-30 times higher than that in the United States and Europe. Knowing the true epidemiology of KD in each country and the availability of publications of KD epidemiology also could benefit general health care providers and general population. This would enable the early detection and treatment of KD, ultimately reducing the incidence of coronary artery complications and mortality. Therefore, efforts to investigate the true epidemiology of KD should be continued in every country using a questionnaire survey, National Health Insurance system data, or combined methods depending on each country's medical environment to ensure high-quality care of patients with KD.

Brain tumors are a mixed group of neoplasms that originate from the intracranial tissues and the meninges with degrees of malignancy varying greatly from benign to aggressive. Not much is known about the epidemiology of primary malignant brain tumors (PMBTs) in our population in North-East India. In this analysis, an attempt was made to identify the age groups, gender distribution, topography and different histological types of PMBT with data from a hospital cancer registry. A total of 231 cases of PMBT were identified and included for the present analysis. Our analysis has shown that most of PMBT occur at 20-60 years of age, with a male to female ratio of 2.3:1. Some 70.5% of cases occurred in cerebral lobes except for the occipital lobe, and astrocytic tumors were the most common broad histological type. In our population the prevalence of PMBT is 1% of all cancers, mostly affecting young and middle aged patients. As brain tumors are rare, so case-control analytic epidemiological studies will be required to establish the risk factors prevalent in our population.
