Abstract
Introduction: Based on statistical and epidemiological studies, cancer is the third most common cause of death after heart diseases and accidents, therefore planning to control cancer is essential for public health. Cancer registration is an important part of cancer control, and the collected data could be useful in etiological studies, and health programming to prevent and treat the disease. In this study cancer incidence and cancer registration in Markazi province investigated. Materials and Methods: In this descriptive study, data related to cancer were collected from the health center of Markazi province, from 2001 to 2006. Then the prevalence and incidence of different kind of cancer were determined. Results: Results showed that the top ten cancers among women were: 1-Breast 2-Skin 3-Stomach 4-Colorectal 5-Lung 6-Uterus 7-Bladder 8-Lymphoma 9-Thyroid 10-Esophagus, and the ten most prevalent cancers among men were: 1-Skin 2-Bladder 3-Stomach 4-Lung 5-Prostate 6-Colon and Colorectal 7-Esophagus 8-Lymphoma 9-Testese 10-Gall bladder. Conclusion: In this investigation we also compared cancer incidence and distribution in Markazi province with national rates and our results showed that in some years, cancer statistics is different from national statistics which it may be due to different environmental and epidemiological factors.

Abstract
Background: Chemical weapons are among the most non-humanistic types of man-made weapons. These gases can cause problems like breathing disorders and other serious illnesses, such that nearly 80 percent of wounded people in Iran have signs of coughing, exuding, and asthma. The aim of this study is to use the results of spirometry tests that are cheap in calculating the probability of illnesses in those exposed. Materials and Methods: In this cross-sectional-analytic study, data related to 1865 individuals wounded by chemical weapons in Sardasht who had been exposed to sulfur mustard were extracted from the existing medical files in Bonyad Janbazan Office. Data analysis was done through the logistic regression method while for evaluating the validity of this model, COX- SNEL was utilized. The spirometry device used in this study was Chest HI801 which was made in Japan. Results: Women formed %23.6 of the population and the rest %76.4 were men. Also, %48.7of the participants were under 40 and %51.3 were 40 and above. Mean age of men was 45.2(11.27) while this was 48.53(14.43) for women. Totally, %48.6 of participants were ill while %51.4 were reported to be healthy. Mean of FEV1 was measured to be 81.78 (21.81) and regression model parameters were as follows: constant =0.465, sex= -0.478, age= 0/29, and FEV1= -0/128. Conclusion: Through the obtained model, the probability of disease incidence in those exposed to sulfur mustard can be computed in a more economic way which can compete with the more expensive, invasive methods.

Abstract
Background: Prostate cancer is one of the most common cancers in men which its incidence rate and associated mortality and morbidity are on the rise. The aim of this study was to investigate the epidemiology of prostate cancer in Fars province between 2003 and 2008 years. Materials and Methods: In this epidemiological study, using Fars province cancer registry data, the incidence rates were calculated per 100,000 people and age standardized incidence rate (ASR) was measured by direct method using the world standard population. Data were analyzed by SPSS, version 16, and Microsoft Excel, version 2007. Cochrane Armitage Test for linear trend was used for evaluation of the incidence trend by running Winpepi software. Results: Over a 6-year period, 1212 cases were recorded in Fars province. The ASR of prostate cancer in these six years was 4.69, 7.16, 15.09, 14.04, 16.65 and 16.02, respectively, which revealed significantly increasing trends. The highest incidence rate was observed in 80 and upper age group. Conclusion: The ASR of prostate cancer in Fars province is significantly lower than other parts of the world, especially in more developed countries. This can be due to absence of screening programs and/or cancer registry.

Abstract
Background: Cancer is one of the most common causes of deaths in the world. Cancer incidence and prevalence is increasing in the world. There is no clear trend is available on incidence of these cancers in Iran, therefore, this study aimed to determine the incidence of 10 common cancers among Iranian women from 2003 to 2009.
Materials and Methods: A cross-sectional study was conducted by analyzing existing data. Data from a national registry of cancer cases were received. Data included the records from the cancer registry system in Iranian women during 2003 to 2009. The incidence rates were then standardized using direct method. We used Cochrane Armitage Test for linear trend by Winpepi software to determine the variation in the incidence of cancers.
Results: The results show that the proportion of all cancers is rising in women as compared to all population. Breast, skin, colorectal, gastric, esophageal, thyroid, leukemia, ovary, brain and uterus were the most common cancer among Iranian women. During the years of the survey, these cancers are significantly increased.
Conclusion: The results of this study showed that the incidence of cancer in women is increased. screening programs can be useful in reducing the cancers.

Abstract
Background: Cancer in the elderly is rising increasingly. According to the population structure in Iran, it is necessary to conduct a study to examine the epidemiology and trends in cancer incidence in the elderly in Iran. So, the aim of this study was to investigate the epidemiology and trends in cancer incidence in Iranian elderly from 2003 to 2009.
Materials and Methods: This cross-sectional study was conducted by analyzing existing data obtained from the National Cancer Registry System in Iran. In this stucly, all records of elderly cancer cases in Iran during 2003 to 2009 were investigated. The age- specific incidence rates of reported cases were estimated by using direct standardization method and the world standard population. We used Cochrane Armitage Test for linear trend by Winpepi software to study the trends in cancer incidence.
Results: stuolying statistics of Cancer Registry center shows that the incidence of cancer increases with age and most cases of cancer occur commonly in elderly people (aged over 60), so that, the highest number of cancer cases diagnosed in people aged 80-84, but it decreases after the age of 85. The most common cancer among the elders, in this period (2003-2009), was the skin cancer. Also, according to the statistics, cancers are more prevalent among older men than older women.
Conclusion: with due attention to the results, the trend of incidence of cancer and its various types in the elders is increasing with age. The implementation of screening programs and necessary trainings in the field of early detection and the avoidance of exposure to risk factors to reduce the risk of cancer in Iranian elderly can be useful.
