  • 본 연구에서는 전라북도 지역암등록본부로부터 2001년부터 2010년까지 10년간 수집된 암등록 자료를 토대로 전라북도 지역의 성별, 연령군별, 호발암별 암발생률 비교 분석과 변동 추이를 살펴보았으며, 또한 국제암연구소에서 제시하는 평가 지표를 기반으로 암등록자료의 질적 수준을 평가하였다. 전라북도 지역의 암발생률 통계 및 암등록 자료의 질 관리 지표는 전북지역암센터의 지역암등록본부로부터 수집되었다. 모든 암들에 대한 성별조발생율(CR)과 연령표준화발생률(ASR)의 10년간 추이를 살펴보았으며, 남녀 5대 호발암에 대한 ASR의 10년간 추이를 분석하였다. 또한 전라북도 지역암등록본부의 암등록 자료에 대한 년도별, 성별, 호발암별 질적 수준을 평가하기 위해 충실도와 타당도를 분석하였다. 충실도 평가를 위해 사용된 지표는 사망/발생비(MI%)와 연령별 발생률 곡선이며, 타당도 평가를 위해 사용된 지표는 연령 미상률(UNK%), 현미경적 확진율(MV%) 그리고 사망진단서에서만 확인가능한 환자의 분율(DCO%)이다. 암 발생률의 10년간 변동 추이는 joinpoint 회귀분석 도구를 이용하였으며, 해당 기간에 대한 연평균 암발생 변화율(AAPC)을 측정하였다. 10년간 전라북도 지역에서의 남성 호발암 순위는 위암이 22.2%로 가장 높았으며, 다음으로 폐암 16.6%, 대장암 12.8%, 간암 12.3%, 전립샘암 6.2% 순으로 나타났다. 여성에서는 갑상샘암이 17.8%로 가장 높았고, 위암 14.7%, 유방암 11.6%, 대장암 11.5%, 폐암 7.7% 순으로 나타났다. 10년 동안 모든 암들에 대한 연령표준화발생률(ASR)을 살펴보면 전체적으로 36.5% 증가하였다. 성별에 따른 ASR 증가율을 살펴보면 남성에서는 13.7%, 여성에서는 68% 증가하였다. 성별 호발암의 연간 변동 추이를 살펴보면 남성의 위암, 폐암, 간암 발생률은 각각 연평균 1.8%, 0.8%, 3.2% 감소하는 추세를 보이고 있으나, 대장암과 전립샘암은 각각 4.9%, 15.1% 증가하는 추세를 보였다. 여성에서는 5대 호발암중 유일하게 위암이 연평균 0.6% 감소하는 추세를 보였으나, 유방암, 대장암, 폐암은 각각 연평균 5.6%, 2.7%, 2.2% 증가 추세를 보였고, 특히 갑상샘암은 연평균 29.6%의 급격한 증가 추세를 보였다. 암등록 자료의 질적 수준 평가에서 충실도 평가 지표인 MI%는 남성에서 2001년 39.4%에서 2010년 32.4%로 낮아졌고, 여성의 경우 2001년 32.2%에서 2010년 23.5%로 낮아져 적정한 수준을 유지하였다. 타당도 평가 지표인 UNK%는 전라북도 지역에서 10년간 남녀 모두 0%로 나타났으며, DCO%는 남성에서 2001년 5.6%에서 2010년 1.3%로 낮아졌고, 여성에서는 2001년 6.1%에서 2010년 1.8%로 낮아져 암등록 자료의 정확성이 향상되었다. MV%는 남성의 경우 2001년 76.3%에서 2010년 88.5%로 증가하였고, 여성의 경우 2001년 78.4%에서 2010년 90.8%로 증가하여, 남녀 모두에서 암진단의 정확성이 높아진 것으로 확인되었다. 전라북도의 10년간 암발생률 추이를 분석한 결과 남성보다 여성에서 암발생률이 증가하고 있으며, 특히 남성에서는 대장암과 전립샘암이, 여성에서는 갑상샘암과 유방암이 증가하고 있음을 확인하였다. 또한 전라북도 지역암등록본부의 암등록 자료의 질관리 수준이 향상되고 있음을 확인하였다. 향후 연구에서는 대도시지역 또는 전라북도와 유사한 다른 지역과의 지역별, 연령별 호발암 및 암발생률 추이를 심층적이고 다각도로 비교 분석하여 향후 국가 차원의 암관리 대책 마련과 암 조기검진사업 추진 등의 보건 정책을 수립하는데 이와 같은 통계 자료가 반영될 수 있도록 해야 할 것이다.

  • After emerging of Microsoft Kinect, the interest in three-dimensional (3D) depth image was significantly increased. Depth image data of an object can be converted to 3D coordinates by simple arithmetic calculation and then can be reconstructed as a 3D model on computer. However, because the surface coordinates can be acquired only from the front area facing Kinect, total solid which has a closed surface cannot be reconstructed. In this paper, 3D registration method for multiple Kinects was suggested, in which surface information from each Kinect was simultaneously collected and registered in real time to build 3D total solid. To unify relative coordinate system used by each Kinect, 3D perspective transform was adopted. Also, to detect control points which are necessary to generate transformation matrix, 3D randomized Hough transform was used. Once transform matrices were generated, real time 3D reconstruction of various objects was possible. To verify the usefulness of suggested method, human arms were 3D reconstructed and the volumes of them were measured by using four Kinects. This volume measuring system was developed to monitor the level of lymphedema of patients after cancer treatment and the measurement difference with medical CT was lower than 5%, expected CT reconstruction error.

  • Introduction: Khon Kaen Cancer Registry (KKCR) was established in 1984. KKCR aims to collect all cancer cases in Khon Kaen Province. The poorly qualified data may lead to distort the cancer burden and misinterpretation of policy maker. Objective: To assess data quality in childhood cancer between 1990 and 2007 in Khon Kaen Province, Thailand. Materials and Methods: Data of childhood cancer cases aged less than 20 years diagnosed during 1990-2007 were retrieved from the population-based data set of KKCR. All childhood cancer data were verified before data entry. Internal consistency, percentage of morphological verification (MV%) and cancer cased of the basis of diagnosis by death certificate only (DCO%) were evaluated. The age-adjusted rate (ASR) was calculated by standard method. Results: The data of childhood cancer from KKCR is acceptably qualified which reflects the quality of the whole registration.

  • Gastric cancer has been the most commonly diagnosed cancer in Korea although the age-standardized mortality and incidence has decreased gradually during last two decades. $Helicobacter$ $pylori$ infection and cigarette smoking are well-established risk factors, and the role of dietary factors, such as salted foods, fresh vegetables and fruits, soy foods, and processed or grilled meats on gastric carcinogenesis has been suggested. In this review, we review national and international gastric cancer statistics, studies on environmental risk factors conducted in the Korean population, and gastric cancer screening activities.

  • This paper presents a method that registers a lymphoscintigraphy to the real image captured by a CMOS camera, which helps surgeons to easily and precisely detect sentinel lymph nodes for sentinel lymph node biopsy in breast cancer patients. The proposed method consists of two steps: pre-matching and image registration. In the first step, we localize fiducial markers in a lymphoscintigraphy and a real image of a four quadrant bar phantom by using image processing techniques, and then determines perspective transformation parameters by matching with the corresponding marker points. In the second step, we register a lymphoscintigraphy to a real images of patients by using the perspective transformation of pre-matching. To examine the accuracy of the proposed method, we conducted an experiment with a chest mock-up with radioactive markers. As a result, the euclidean distance between corresponding markers was less than 3mm. In conclusion, the present method can be used to accurately align lymphoscintigraphy and real images of patients without attached markers to patients, and then provide useful anatomical information on sentinel lymph node biopsy.

  • Background: Recent estimates suggest that in the Lao People's Democratic Republic (Lao PDR) the burden of cancer in terms of DALYs lost is amongst the highest in South East Asia. As such, increasingly cancer is becoming an important public health concern in the country. Lao PDR however has no population-based cancer registry and only one hospital-based registry. Cancer treatment within the country is extremely limited. Patients who can, may travel to neighboring countries for treatment, but little information about this is available in the country. The aim of this study was to estimate some of the otherwise largely unknown parameters of the cancer burden in Lao PDR. Materials and Methods: This is a retrospective, descriptive study based on the records of 847 Lao cancer cases treated with surgery, radiation and chemotherapy at Srinagarind Hospital, Khon Kaen University, in Thailand between 1988 and 2010. Results: The annual rate of registration of Lao cancer cases fluctuated, but showed an increasing trend. Most cancers were diagnosed by histology (65.2%), and a combination of endoscopy and radiology (15.6%). In most cases (70.2%) the stage of cancer at diagnosis could not be determined. In those whose stage could be identified, 54.0% were at the final stage (Stage IV). Among males, the commonest cancer sites were the liver (16.1%), blood (12.3%) and nasopharynx (10.6%). Those in female patients were the cervix (22.2%), breast (14.6%) and blood (8.1%). Conclusions: This study indicates that despite some fluctuations, the number of Lao cancer patients presenting at Srinagarind Hospital, Khon Kaen, gradually increased between 1988 and 2010. The unfavorable pattern of late-stage cancer diagnosis among male and female patients suggests a need for cancer control interventions and the establishment of cancer registration and treatment facilities within Lao PDR.

  • In Nepal, while no population based cancer registry program exists to assess the incidence, prevalence, morbidity and mortality of cancer, at the national level a number of hospital based cancer registries are cooperating to provide relevant data. Seven major cancer diagnosis and treatment hospitals are involved, including the BP Koirala Memorial Cancer hospital, supported by WHO-Nepal since 2003. The present retrospective analysis of cancer patients of all age groups was conducted to assess the frequencies of different types of cancer presenting from January 1st to December 31st 2012. A total of 7,212 cancer cases were registered, the mean age of the patients being 51.9 years. The most prevalent age group in males was 60-64 yrs (13.6%), while in females it was 50-54 yrs (12.8%). The commonest forms of cancer in males were bronchus and lung (17.6%) followed by stomach (7.3%), larynx (5.2%) and non Hodgkins lymphoma (4.5%). In females, cervix uteri (19.1%) and breast (16.3%), were the top ranking cancer sites followed by bronchus and lung (10.2%), ovary (6.1%) and stomach (3.8%). The present data provide an update of the cancer burden in Nepal and highlight the relatively young age of breast and cervical cancer patients.

  • Lung cancer is the most commonly diagnosed cancer and the leading cause of cancer-related deaths worldwide. Globally, there were an estimated 1.8 million new cases and 1.59 million deaths in 2012. In Korea, the incidence of lung cancer is increasing and 24,267 (47.6/100,000) patients with lung cancer were registered at the Korea Central Cancer Registry in 2015. Previous nationwide surveys of lung cancer were performed in 1998 by the Korean Academy of Tuberculosis and Respiratory Diseases and in 2007 by the Korean Association for Lung Cancer (KALC), but the studies faced difficulties in maintaining lung cancer registry because of limitations regarding the Private Information Protection Act. To produce unbiased and reliable epidemiological data, the KALC and Korean Central Cancer Registry developed a detailed lung cancer registry (KALC-R) data structure. Following a pilot survey of 489 lung cancer cases in 2013, about 10% of the sampled lung cancer cases from the Korean Central Cancer Registry are surveyed each year. With the analysis of detailed data from the KALC-R, an important epidemiological background for scientific research or policy development is expected to be generated.

  • The Delhi Population Based Cancer Registry data during the period 2003-2007 were used to describe the epidemiology of primary malignant brain and central nervous system tumors in Delhi. A total of 1989 brain and CNS tumors cases in 1291 males and 698 females were registered during the period 1st January 2003 to 31st December 2007. The age adjusted (world population) incidence rates were 3.9 per 100,000 for males and 2.4 per 100,000 for females. Gliomas were the most frequently reported histology both in males (26.6%) and females (23.2%). A male predominance in incidence was observed for all histological classifications. The rates in Delhi are low compared to the incidences reported from developed countries.
