A cross-sectional study was conducted among nursing staff of a missionary hospital of Delhi in June 2009. All the nurses were invited to participate in the training programme on breast cancer and techniques of breast self examination (BSE). A questionnaire was administered to all 259 participants seeking information on their level of awareness regarding breast cancer and relevant screening guidelines. With the help of 5 training workshops all the nurses were imparted training regarding the most appropriate technique of doing breast self exams. The mean age of the participants was 35.8 years. Out of a total of 259 nursing staff members 77.2% correctly answered all the 10 questions regarding high risk factors for breast cancer and after the training programme this increased to 100% (p<0.05). Only 65.2% of the participants gave correct responses to all the 8 questions regarding correct technique of performing a BSE, which after the training programme increased to 99.3% (p<0.05). At the baseline only 56.8% knew all the three screening methods correctly and after the intervention 98.7% could correctly mark the responses regarding screening (p<0.05). The actual practice of following the screening guidelines amongst the nursing staff was poor. Only 26 (10.03%) had ever done a BSE, none performed it monthly, 58 (22.4%) had ever gone themselves for a CBE and 18 (6. 94%) had ever undergone mammography.

Background: Although breast cancer is the most common cancer in women, economic evaluation of breast cancer screening is not fully addressed in developing countries. The main objective of the present study was to analyze the cost-effectiveness of breast cancer screening using mammography in 35-69 year old women in an Iranian setting. Materials and Methods: This was an economic evaluation study assessing the cost-effectiveness of a population-based screening program in 35-69 year old women residing in rural areas of South east Iran. The study was conducted from the perspective of policy-makers of insurance. The study population consisted of 35- to 69-year old women in rural areas of Kerman with a population of about 19,651 in 2013. The decision tree modeling and economic evaluation software were used for cost-effectiveness and sensitivity analyses of the interventions. Results: The total cost of the screening program was 7,067.69 US$ and the total effectiveness for screening and no-screening interventions was 0.06171 and 0.00864 disability adjusted life years averted, respectively. The average cost-effectiveness ratio DALY averted US$ for screening intervention was 7,7082.5 US$ per DALY averted and 589,027 US $ for no-screening intervention. The incremental cost-effectiveness ratio DALY averted was 6,264 US$ per DALY averted for screening intervention compared with no-screening intervention. Conclusions: Although the screening intervention is more cost-effective than the alternative (noscreening) strategy, it seems that including breast cancer screening program in health insurance package may not be recommended as long as the target group has a low participation rate.

Objectives : The purpose of this study was to examine the present status of cancer screening recommendations(beginning age, interval, recommended screening methods, etc.) by physicians and analyze the association between physician's characteristics and the content of their recommendations. Methods : Data were collected from March 1 to April 30 of 1997, and 373 physicians who were from different hospital settings all over Korea were interviewed by telephone about their screening recommendations for stomach, cervical and breast cancer for these who provided cancer screening services. Results : For stomach cancer screening, respondents recommended that cancer screening begin at 40 years of age(57.8%), with a 1 year interval(77.2%), and by gastrofibroscopy (86.2%). For cervical cancer screening, respondents recommended that cancer screening begin at 25 years of age(42.0%), with a 1 year interval(67.8%), and by using a Pap smear(100.0%). For breast cancer screening, respondents recommended that cancer screening begin at 35 years of age(38.7%), with a 1 year interval(57.3%), and by mammography (97.3%). Conclusions : To establish appropriate cancer screening recommendations for Korea, if may be useful to consider the above results concerning medical care providers.

Background: The coverage of breast and cervical cancer screening has only slightly increased in the past decade in Thailand, and these cancers remain leading causes of death among women. This study identified socioeconomic and contextual factors contributing to the variation in screening uptake and coverage. Materials and Methods: Secondary data from two nationally representative household surveys, the Health and Welfare Survey (HWS) 2007 and the Reproductive Health Survey (RHS) 2009 conducted by the National Statistical Office were used. The study samples comprised 26,951 women aged 30-59 in the 2009 RHS, and 14,619 women aged 35 years and older in the 2007 HWS were analyzed. Households of women were grouped into wealth quintiles, by asset index derived from Principal components analysis. Descriptive and logistic regression analyses were performed. Results: Screening rates for cervical and breast cancers increased between 2007 and 2009. Education and health insurance coverage including wealth were factors contributing to screening uptake. Lower or non-educated and poor women had lower uptake of screenings, as were young, unmarried, and non-Buddhist women. Coverage of the Civil Servant Medical Benefit Scheme increased the propensity of having both screenings, while the universal coverage scheme increased the probability of cervical screening among the poor. Lack of awareness and knowledge contributed to non-use of both screenings. Women were put off from screening, especially Muslim women on cervical screening, because of embarrassment, fear of pain and other reasons. Conclusions: Although cervical screening is covered by the benefit package of three main public health insurance schemes, free of charge to all eligible women, the low coverage of cervical screening should be addressed by increasing awareness and strengthening the supply side. As mammography was not cost effective and not covered by any scheme, awareness and practice of breast self examination and effective clinical breast examination are recommended. Removal of cultural barriers is essential.

Objective: To assess the appropriate follow-up interval, and rate and timepoint of cancer detection in women with Breast Imaging Reporting and Data System (BI-RADS) 3 lesions on screening ultrasonography (US) according to the type of institution. Materials and Methods: A total of 1451 asymptomatic women who had negative or benign findings on screening mammogram, BI-RADS 3 assessment on screening US, and at least 6 months of follow-up were included. The median follow-up interval was 30.8 months (range, 6.8-52.9 months). The cancer detection rate, cancer detection timepoint, risk factors, and clinicopathological characteristics were compared between the screening and tertiary centers. Nominal variables were compared using the chi-square or Fisher's exact test and continuous variables were compared using the independent t test or Mann-Whitney U test. Results: In 1451 women, 19 cancers (1.3%) were detected; two (0.1%) were diagnosed at 6 months and 17 (1.2%) were diagnosed after 12.3 months. The malignancy rates were both 1.3% in the screening (9 of 699) and tertiary (10 of 752) centers. In the screening center, all nine cancers were invasive cancers and diagnosed after 12.3 months. In the tertiary center, two were ductal carcinomas in situ and eight were invasive cancers. Two of the invasive cancers were diagnosed at 6 months and the remaining eight cancers newly developed after 13.1 months. Conclusion: One-year follow-up rather than 6-month follow-up may be suitable for BI-RADS 3 lesions on screening US found in screening centers. However, more caution is needed regarding similar findings in tertiary centers where 6-month follow-up may be more appropriate.

유방 촬영술(Digital mammography)은 유방암의 조기 진단에서 매우 중요한 진단 방법으로서 비촉지성 유방암의 조기 발견율을 높여 유방암에 따른 여성의 사망률을 감소시키고 있다. 그 중에서도 유방 병변의 미세석회화(Microcalcification)는 조기 유방암의 진단에 있어서 중요한 병변으로 보고 되고 있으며, 선별 검사로 임상적 유용성이 확립된 상태이다. 유방 촬영술에서 미세석회화 소견은 영상의학과 전문의가 판독하여 조직 검사에서 양성 및 악성 병변에 대하여 각각 군집의 개수, 군집 당 석회화 수, 미세석회화 크기와 범위, 미세석회화 형태, 동반 종괴의 유무 등을 분석하여 최종적으로 진단을 확정한다. 그러므로 군집화된 미세석회화의 정보는 유방암 예측에 있어 임상적인 실질 정보를 가지고 있으며, 의사에게 진단을 위한 검사의 기본적인 가이드라인을 제시한다. 따라서 본 연구에서는 유방 촬영술의 디지털 영상에 나타난 미세석회화의 정량적인 계산을 위해서 DoG filter, Adaptive thresholding, Expectation Maximization의 3단계를 제안한다. 제안한 알고리듬을 실험을 통하여 군집화 및 각 클러스터 내의 미세석회화의 분포 개수, 길이를 측정하였으며, 임상의 사에게 디지털 유방영상의 분석을 통하여 초기 유방암 진단의 지표를 제시할 것으로 사료된다. 그리고 이는 객관적인 유방암 컴퓨터자동검출(CAD)에 사용될 수 있는 병변의 정보로서 가능성을 보였다.

유방촬영술은 유방암의 조기검진을 위해 시행되는 대표적인 검사이다. 하지만 유방 구성물질의 물리적 특성에 의존하는 유방촬영상은 병변의 악성 또는 양성 여부에 대한 정보 제공이 불가능하다. 이중에너지 영상 감산법을 시행하는 경우 유방촬영상에서 특정 물질에 대한 정보를 추출할 수 있지만 피폭선량을 증가시킬 뿐만 아니라 물질분리의 정확도를 감소시키는 단점이 있다. 본 연구에서는 물질의 선감약계수를 적용한 유방팬텀을 모사하여 광자계수검출기 기반 이중에너지 유방촬영에서 특정 물질에 대한 가중함수를 적용하여 분리의 정확도를 향상시킬 수 있는 기술을 제안하였다. 그리고 유방팬텀영상으로부터 물질분리의 정확도를 평가하기 위해 대조도 및 잡음 특성을 분석하였다. 분석 결과 이중에너지 가중 영상 감산법의 악성종양에 대한 대조도는 일반적인 유방촬영과 이중에너지 영상 감산법에 비해 각각 0.98, 1.06배로 큰 차이가 없다. 그렇지만 이중에너지 가중 영상 감산법 적용 시 양성종양에 대한 대조도가 0에 근사하기 때문에 양성종양에 대한 악성종양의 상대적인 대조도가 13.54배로 크게 향상된 것으로 확인되었다. 따라서 본 연구에서 제안하는 이중에너지 가중 영상 감산법은 유방촬영 진단의 정확도 향상에 기여할 수 있을 것이다.

유방암이 여성암 발생 1위를 차지함에 따라 선별검사로서 유방촬영율 또한 증가하였다. 유방촬영술은 병변의 유선 조직이나 지방조직 등 주위 조직의 X선 흡수차가 작고 미세 석회화를 묘출해야 되는 어려운 점이 있어 정확한 진단을 위해서는 양질의 영상이 요구되며 이를 위해서는 촬영장비의 성능관리와 화질관리가 필요하다. 이에 본 조사에서는 정도관리가 실제적으로 잘 이루어지고 있는지 알기위하여 광주광역시 소재의 의료기관중 유방암검진기관으로 등록되어 있는 기관 37곳을 대상으로 하여 2008년 7월 1일부터 8월 31일까지 62일 동안 유방촬영장비의 정도관리 실태에 관하여 설문조사하였다. 유방촬영장비의 장치적 특성에 대한 조사결과 사용하는 장비에 대하여 모르고 사용하는 경우가 많았다. 필름과 CR을 이용하는 병원은 각각 19곳(49%)이었고 DR을 이용하는 병원도 1곳 있었다. 또 종합병원의 대부분은 CR을 이용하고 있었으며 의원은 필름을 사용하는 경우가 많았다. 정도관리 방법에 대한 질문 결과 38%만이 매뉴얼대로 점검하고 있었다. 또 조사한 병원 전수가 전문 업체에 정도관리를 맡기고 있었다. 그 이유로는 전담인력, 시간, 거리 등 한계점 때문에 맡긴다는 대답이 65%로 가장 많았으며 기자재가 없어서 맡긴다는 대답이 44%로 그 다음으로 많았다. 이러한 결과는 정도관리가 형식적으로 이루어지고 있음을 반영하며 전문 업체에 의존하므로 점검 항목자체에 수동적이고 무관심한 것으로 사료된다. 따라서 정기적인 교육을 실시하여 정도관리에 관한 인식을 높이고 방사선사의 적극적인 참여를 통하여 올바른 정도관리를 할 수 있도록 하여야 한다. 이러한 노력과 더불어 전담인력이나 기자재 등 문제점을 해결함으로써 정도관리의 발전에 기여할 수 있을 것이다.

Purpose: Breast cancer is becoming increasingly prevalent among young Korean women. During pregnancy, women's concern regarding their breasts heightens. Thus, pregnancy provides a window of opportunity for breast cancer prevention and management along with antenatal care. This study developed and evaluated an integrated breast health program for pregnant women. Methods: This study employed a non-equivalent control group and non-synchronized design (22 experimental, 29 control). Women pregnant for over 28 weeks participated. The two-session integrated breast health program focused on breast management during breastfeeding and education about breast cancer prevention and early screening. Results: During the early postpartum period (within three months after the program), there were statistically significant differences in knowledge and attitude about breast cancer and breast self-examination before and after the program. There were also statistically significant differences in BSE at 6 and 12 months after the program and mammography at 12 months after the program. However, there were no statistically significant differences in clinical breast examination and breast ultrasonography at 6 and 12 months after the program. Conclusion: The integrated breast health management program was effective in increasing knowledge and improving attitudes regarding breast cancer, BSE, and early screening practices among pregnant women. Further studies should consider providing breast health programs differently for each phase of pregnancy and continuing the same after delivery.
