  • Genistein, a soybean-originated isoflavone, is an anticancer agent preventing various cancers including prostate, uterus, and mammary gland cancers. However, recently, genistein has been classified into a potential endocrine disruptor, because it binds to estrogen receptors and causes reproductive disturbances in some animals.(omitted)

  • Microsatellite instability (MSI), which is caused by a deficient mismatch repair system, is seen in most of the hereditary non-polyposis colon cancers (HNPCC) and a portion of sporadic colorectal cancers. Forty unselected colorectal cancer patients were analyzed for MSI using silver stain plus kit. The overall incidence of MSI in studied cases was 17% (7/40). The incidence is similar result with previous study. MSI in colorectal carcers was more prevalent in moderative differentiated adenocarcinoma than well differentiated adenocarcinoma

  • The microwave exposure device for microwave breast cancer detection consists of RF transceiver and several antennas. The microwave information of object acquired from the microwave exposure device can be calculated permittivity and conductivity by using the inverse scattered analysis. In this paper, we have developed the software for detecting breast cancers based on microwave tomography, by which users not only can check out the existence of breast cancers through the permittivity and conductivity information analysis of the object's internal, but also can analysis easily information for distribution of breast cancers. The developed software provides the function for visualizing the captured permittivity and conductivity information as 2D or 3D color images on which users can easily detect the existence of breast cancers. For more detailed analysis of tomography images, the proposed software also has provided the functions for displaying their cutting profiles as well as position and size information of special area in them.

  • Background: Cancer is a leading cause of death throughout the world. Increasing life expectancy and aging population are important factors for increasing cancer incidences in developing countries. National programs are essential for prevention and control of cancer in any society. This study aimed to investigate cancer epidemiology and trends in the province of Hamadan, located in Northwest Iran. Materials and Methods: This analytical study was carried out based on cancer registry data from 2004 to 2009 in the province of Hamadan, analyzed using STATA (version 12) software for descriptive tests and Join point 4.1.1.1 software for analytical tests. Results: There were 7,767 registered cases of cancer during the 6 years studied. Of the total cases registered, 59.1% (4,592 cases) involved men and 40.9% (3,175 cases) occurred in women. Age-standardized incidence rates (ASR) increased from 72.9 to 132.0 in males and 48.2 to 115.0 in females during the 6 years of the study (p<0.001). The most common cancers were skin, stomach, breast, bladder, and leukemia. In women, teh most common were breast, skin, stomach, colorectal, and leukemia, in that order, and in men skin, stomach, bladder, leukemia, and prostate cancers. Conclusions: The cancer incidence is greater in men that women in this region but with increasing trends in both sexes. Planning regarding education in prevention of exposure to risk factors and control strategies is required to decrease the incident cases. Screening programs for common cancers in older age groups might be helpful to reduce the disease impact.

  • Background: Gastric and esophageal cancers are among the most lethal human malignancies worldwide. Of all malignancies estimated in Iran (47,100), gastric and esophageal cancers were responsible for 7,800 and 3,500 deaths in 2008 respectively. The present study aimed to provide an image of patho-epidemiological characteristics with their trends during two past decades with emphasis on topographic, morphologic, and some demographic features. Materials and Methods: In a hospital-based retrospective study in 2009, all pathological reports from esophageal endoscopies and gastric biopsies through a 20 years period (1989-2008) were collected and analyzed in four interval periods(five years each). Also, all eligible samples in hospital archives were enrolled for further testing. Besides, demography, topography and morphology of all samples were determined and analyzed by statistical software. Results: No significant statistical difference was seen in frequency of espohageal and gastric tumors throughout the study. Esophageal cancer cases were older than gastric. Sex ratio was 2.33/1 and men had a higher rate of both esophageal and gastric tumors. Stomach cancer included 64.3% of all cases. Inferior third and end of esophagus were common locations for esophageal tumors whereas proximal stomach was common for gastric tumors. Squamous cell carcinoma and adenocarcinoma were common morphological types of tumors in esophagus and stomach respectively. Conclusions: Morphological trends showed an increase of esophageal adenocarcinoma and diffuse/intestinal ratio in stomach cancers. Trends in incidence from gastric cancer decreased based on topographic studies but we could not find a topographical trend toward cadia.

  • Purpose: The aim of this study was to identify the effects of hope and Self-efficacy on posttraumatic growth in mothers of children with cancers. Methods: A descriptive research design was used and 102 mothers participated in the study. They were primary care givers of children with cancers who were being treated at a tertiary care hospital in Seoul. A structured questionnaires which measured the degree of hope, self-efficacy, and posttraumatic growth was used for data collection. Data analysis was conducted using descriptive statistics, independent t-test, one-way analysis of variance, Pearson correlation coefficient, and multiple regression. Results: There were positive correlations between posttraumatic growth and hope (r=.44, p<.001) as well as self-efficacy (r=.33, p=.003). The major predictors of posttraumatic growth were religion (${\beta}=0.29$, p=.001), only child or first child (${\beta}=-0.25$, p=.015), the number of children in the family (${\beta}=0.25$, p=.016), and hope (${\beta}=0.38$, p=.001). This model explained about 30.4% of the total variables found in posttraumatic growth (F=9.84, p<.001). Conclusion: The findings from this study show that posttraumatic growth in mothers of children with cancers is largely predicted by hope indicating a need to develop nursing intervention programs to enhance hope in these mothers.

  • Surgical resection is the most effective treatment in operable lung cancers. However, less invasive local treatments are being applicated to the patients having high surgical risk due to their poor general condition. Cryosurgery is known to be highly effective and safe in the treatment of liver and prostate cancers and it is also being applicated in the treatment of lung cancers, especially with the excision of tracheal mass and lung parenchymal cancers. In our hospital, we have tried a less Invasive method, the cryotherapy, to a patient who had a newly developed lung cancer at his right lower lobe after he had been treated with right upper lobe resection and left upper lobe resection due to bilateral lung cancels. After the treatment, he is being followed up at our out patient department for 2 years. Here, we present the method and result that have been applicated in this case.

  • Background: Nutrition transition is a global health problem, especially in developing countries. It is known as an important factor for development of different types of health conditions including cancers. Objectives: We aimed to assess the pattern of nutrition transition in a high-risk area for upper gastrointestinal cancers in Northern Iran during the last decade. Materials and Methods: This cross-sectional study was conducted on households of Golestan province, Iran. Data on household food consumption between 2001 and 2010 were obtained from the Statistical Center of Iran. The proportions of households with medium/high consumption of main foods were calculated for each year. Joint point software was used for assessing trends. Annual percent changes (APCs) and 95%CIs were calculated. Results: In total, 12,060 households were recruited. The APCs (95%CI) of the proportion of households medium/high consumption of cereals, vegetables, legumes, fish, dairy products and meats were -3.1 (-4.1 to -2.2), -2.9 (-3.8 to -2.1), -2.3 (-3.2 to -1.4), -2.8 (-3.3 to -2.4), -1.9 (-3.0 to -0.9) and 2.7 (1.2 to 4.3), respectively. Conclusions: We found significant increase in meat consumption among our population between 2001 and 2010. Our results also suggested significant decreasing trend in consumption of so-called healthy foods including, plant foods, fish, and dairy products. Regarding its correlation with health conditions including cancers, nutrition transition should be considered as a priority in health policy making in our region as well as other high-risk populations. It is recommended to conduct community level interventions to increase consumption of plant foods, fish, and dairy products.

  • Background: Biliary tract cancers are rare, and surgical resection is the standard treatment at early stages. However, reports on the benefits of adjuvant treatment following surgical resection are conflicting. This study aimed to evaluate the factors affecting survival and adjuvant treatments in patients with surgically treated biliary tract cancers. Materials and Methods: Patient clinical features, adjuvant treatments, and efficacy and prognostic factor data were evaluated. Survival analyses were performed using SPSS 15.0. Results: The median overall survival was 30.7 months (95% confidence interval [CI], 18.4-42.9 months). Median survival was 19 months (95% CI, 6-33) for patients treated with fluorouracil based chemotherapy and 53 months (95% CI, 33.2-78.8) with gemcitabine based chemotherapy(p=0.033). On univariate analysis, poor prognostic factors for survival were galbladder localization, perineural invasion, hepatic invasion, a lack of adjuvant chemoradiotherapy treatment, and a lack of lymph node dissection. On multivariate analysis, perineural invasion was a poor prognostic factor (p=0.008). Conclusions: Biliary tract cancers generally have poor prognoses. The main factors affecting survival are tumour localization, perineural invasion, hepatic invasion, adjuvant chemoradiotherapy, and lymph node dissection. Gemcitabine-based adjuvant chemotherapy is more effective than 5-fluorouracil-based chemotherapy.
