Lung cancer such as small cell lung cancer(SCLC) and non small cell lung cancer(NSCLC) have high mortality rate, so, we insurance doctors have little interest in their risk. But nowadays there's a lot of development in targeted therapy of NSCLC. Screening by CT scanning and early resection strategy also shows better prognosis. It is helpful for underwriters and insurance doctors to review the current development of targeted therapy of NSCLC and estimation of extra-risk of early lung cancer. The preferred treatment option for patients whose tumors contain EGFR-activating mutations are one of the EGFR-directed tyrosine kinase inhibitors, such as gefitinib or erlotinib. In patients with NSCLC whose tumors harboured an ALK rearrangement, there was 61% objective response rate to crizotinib in the phase 1 study. The median survival progression-free survival was 10 months. Mortality analysis of early lung cancer who were detected by CT screening, MR of 105% and EDR of 1‰ were calculated.

India has maximum genetic materials in early cauliflower, which grow in subtropical conditions. Different disease parameters like linear growth, maximum growth rate per day, AUDPC, apparent infection rate and percent diseased area were calculated in artificially inoculated plants. Apparent infection rate is not co-related with the black rot disease incidence and should never be considered during characterization of disease resistance and varietal screening. Based on the above disease parameters Kunwari-18, Phool Gobhi Kunwari, Kataki-7 and BT-10-2 were selected as moderately resistance to black rot in early cauliflower. These lines can be used for black rot prone area and also for black rot disease improvement programme. Considering the qualitative and quantitative parameters, slow rotting resistance cauliflower lines are selected as such for cultivation and would be best suited in integrated disease programme.

Objectives: With the increase in the number of people who are marginalized in receiving medical services, the role of Seoul National University Hospital as a public hospital is being emphasized. However, many patients are either experiencing delays in receiving medical services or simply being left out as a result of the inaccessibility to the department of social work on part of both the patients and the medical staff. Methods: In order to increase consultation from other departments and the accessibility to the department of social work for the socially marginalized group through early consultation from other departments, the following steps were taken. First, an orientation program for novice medical residents led by clinical social worker was introduced/implemented. Second, posters and brochures on various financial aids programs were produced and distributed. Third, a system of early screening was built/constructed, and once a week rounds and early screening meeting were executed/carried out. Result: The department of social work's rate of consultation from other departments increased by 4.4% compared to last year, while it showed 61% increase for those wards that had an early screening meeting. In addition, the average time of consultation from other departments was reduced by 3.1 days, securing sufficient amount of time for clinical social work services, both in terms of quality and quantity. Conclusion: It is believed that the various promotional activities, along with the strengthening of accessibility to clinical social work services and early consultation on part of social disadvantaged/marginalized group, would undoubtedly help provide quality services to patients and increase their level of satisfaction. In this way, the wards can effectively reduce the number of unnecessary hospital stay days while the hospital can prevent the accumulation of outstanding bills/fees as well as contribute to the publicness of hospitals. The promotion of clinical social work programs in various ways are crucial to ensuring the satisfaction of patients and hospital staff.

Objectives: This retrospective cohort study aimed to estimate the mean sojourn time (MST) of preclinical gastric cancer in Korean men. Methods: The subjects consisted of voluntary male screenees aged 40 to 69 years who underwent subsequent screening gastroscopies after testing negative at a baseline screening performed between January 2007 and December 2011. A new case was defined if gastric cancer cells were present in the biopsy specimens obtained from gastroscopy. The follow-up period was calculated as the number of person-years between the date of baseline screening gastroscopy and positive findings at a subsequent screening. The MST was calculated using transition rates of gastric cancer to determine the best screening interval. Results: Of the 171 979 voluntary male screenees, 61 688 (36%) underwent subsequent screening gastroscopies between January 2007 and December 2011. A total of 91 incident cases were found during 19 598 598 person-years of follow-up. The MST of gastric cancer was 2.37 years (95% confidence intervals, 1.92 to 2.96), and those aged 40 to 49 years had a shorter MST than those 50 to 69 years did. Conclusions: These findings support the 2-year interval of screening recommended by the nationwide gastric cancer screening program in Korea. Further studies for the age-specific MST among women are needed.

Cervical cancer, the third commonest cancer in women worldwide, can be prevented through early detection by cervical screening (Pap smear). The aim of this study was to investigate the attitudes and practice of cervical cancer screening among female undergraduate university students from 25 low, middle income and emerging economy countries. Using anonymous questionnaires, data were collected from 9,194 female undergraduate university students aged 18-26 years (mean age 20.9, SD=2.0) from 26 universities in 25 countries across Asia, Africa and the Americas. Overall, 11.6% of the female students indicated that they had conducted one or more times a cervical (Pap) smear test; 8.3% among 18-20 year-olds and 15.6% among 21-26 year-old students. There was considerable country variation on having had a cervical (Pap) smear test among 21-26 year-old female university students, ranging from 59.2% in Colombia and 50.9% in Barbados to 0% in India and 1.0% in Tunesia. Logistic regression showed that cervical cancer screening importance or positive attitude were highly associated with the cervical screening practice. Moreover, risky sexual behaviour and tobacco use, two cervical cancer risk factors, were associated with screening. Cervical cancer screening practices were found to be inadequate and e fforts should be made to develop programmes that can increase the uptake of cervical cancer screening.

Objectives: Breast cancer is a leading cause of morbidity and mortality in women worldwide. Breast screening in normal and/or asymptomatic women is essential to reduce the burden of breast malignancies. Our study aimed to identify possible risk- and/or co-factors associated with breast screening in North Indian women. Methods: A public health research survey was conducted among 100 women of North Indian ethnicity during clinic visits in a 6-month timeline (April-October 2012). Demographic and clinical data, including mammography screening, were recorded in the questionnaire-based proforma after conducting a 10 minute interview. Written informed consent was taken from all the participants. Results: The mean age of the participants was $32.2{\pm}9.9$ years. Out of 100 women, 6% had family history of breast disease. Breast-related complaints/malignancy, including galactorrhoea, mastitis, axillary lump, fibrocystic disease, fibroadenosis and adenocarcinoma were observed in 41% participants; age stratification revealed that 82.9% of this group (n=41) were <30 years, while 9.7% and 7.3% were >30 years and 30 years of age, respectively. 32% participants underwent mammography screening and 8% had breast ultrasound imaging. Age stratification in the mammography screening group demonstrated that 24 women were <40 years, while 7 women were >40 years. Conclusions: Our pilot study identified possible co-factors affecting breast screening in North Indian women. These findings may be beneficial in early detection of breast abnormalities, including malignancies in women susceptible to breast cancer, and thus aid in future design of cost-effective screening strategies to reduce the increasing burden of breast carcinoma in women worldwide.

Purpose: This study was conducted to survey the cancer screening status of Korean elderly and to analyze factors influencing cancer rescreening intention. Methods: Participants were 262 elderly aged 65 or older who visited medical examination center at D University hospital located in D city. Data were collected from June 1 to July 31, 2012 using a structured questionnaire which included health behavior and cancer screening related characteristics, theory of planned behavior variables, EQ-5D, and cancer screening satisfaction. The data were analyzed by SPSS/WIN 18.0 program. Results: Factors influencing elderly's cancer rescreening intention were 'satisfaction about the cancer screening', 'attitude toward cancer rescreening behavior', 'subjective norm toward cancer rescreening behavior', and 'previous experience with cancer screening in the past 2 years'. Cancer rescreening intention was higher in participants with satisfied experience of cancer screening, more positive in attitude and higher in subjective norm toward cancer rescreening. Cancer rescreening intention was lower when participants were not screened for cancer in the past 2 years. Conclusion: The study results indicate that customized interventions based on influential factors such as subjective norm, attitude toward cancer screening, and cancer screening satisfaction are necessary in order to promote the consistent cancer screening of Korean elderly.

The current study aimed at exploring the knowledge and beliefs of men aged forty years and over towards prostate cancer screening and early detection in three Arab countries. The field work was conducted in three countries; Saudi Arabia, Egypt and Jordan, during the period February through December 2011. Our target population were men aged 40 years and over. It was a population-based cross sectional study comprising 400 subjects at each site. In addition to socio-demographic data, history of the present and past medical illness, practice history of prostatic cancer examination, family history of cancer prostate; participants were inquired about their knowledge and attitude towards prostate cancer and screening behavior using two different likert scales. The percentage of participants who practiced regular prostate check up ranged from 8-30%. They had poor knowledge and fair attitude towards prostate cancer screening behavior, where the mean total knowledge score was $10.25{\pm}2.5$, $10.76{\pm}3.39$ and $11.24{\pm}3.39$ whereas the mean total attitude score was $18.3{\pm}4.08$, $20.68{\pm}6.4$ and $17.96{\pm}5.3$ for Saudi Arabia, Egypt and Jordan respectively. The respondents identified the physicians as the main sources of this information (62.4%), though they were not the main motives for regular checkup. Knowledge was the only significant predictor for participants' attitude in the multiple regression models. Participants' attitudes depends mainly on level of knowledge and quantity of information provided to the patients and their families. Such attitudes should rely on a solid background of proper information and motivation from physicians to enhance and empower behaviors towards prostate cancer screening practices.

Purpose: Regular cancer screening for workers can help prevent cancer or allow early treatment, and is thus beneficial in improving health, reducing costs, and increasing companies' productivity. However, there has been little research on cancer screening rates of workers and related factors. The purpose of this study was to identify cancer screening rates and relevant factors among manufacturing workers. Methods: Using a questionnaire, data were collected from 335 workers aged over 40 years recruited from seven manufacturing companies. The collected information included cancer screenings (stomach, colorectal, breast, and cervical), attitude towards cancer screening, and demographic and job characteristics. Results: 72.5% of workers received stomach cancer screening (SCS), and 43% received colorectal cancer screening (CRCS). Among 86 women, 68.6% received breast cancer screening and cervical cancer screening. The attitude towards cancer screening was $29.5{\pm}3.78$. Workers aged over 51, married, and those working in mobile manufacturing were more likely to have undergone SCS. Workers aged over 51, married, those working in mobile manufacturing, those in workplaces with more than 1,001 employees, and those with more positive attitudes toward cancer screening were more likely to have undergone CRCS. Finally, attitude affected cervical cancer screening. Conclusion: Workers in small-sized workplaces had lower cancer screening rates. Thus, follow-up research should assess the health environment of workplaces and develop educational programs on cancer screening that reflect attitudes towards screening.

Background: Although the incidence of colorectal cancer in Malaysia is increasing, awareness of this cancer, including its symptoms, risk factors and screening methods, remains low among Malaysian populations. This survey was conducted with the aim of (i) ascertaining the awareness level regarding colorectal cancer symptoms, risk factors and its screening among the general populations and (ii) assessing the public preference and willingness to pay for colorectal cancer screening. Materials and Methods: The questionnaire was distributed in eight major cities in West Malaysia during the World Health Digestive Day (WDHD) campaign. Two thousand four hundred and eight respondents participated in this survey. Results: Generally, awareness of colorectal cancer was found to be relatively good. Symptoms such as change in bowel habit, blood in the stool, weight loss and abdominal pain were well recognized by 86.6%, 86.9%, 83.4% and 85.6% of the respondents, respectively. However, common risk factors such as positive family history, obesity and old age were acknowledged only by less than 70% of the respondents. Almost 80% of the respondents are willing to take the screening test even without any apparent symptoms. Colonoscopy is the preferred screening method, but only 37.5% were willing to pay from their own pocket to get early colonoscopy. Conclusions: Continous cancer education should be promoted with more involvement from healthcare providers in order to make future colorectal cancer screening programs successful.
