Chorionic villus sampling has gained importance as a tool for early cytogenetic diagnosis with a shift toward first trimester screening. First trimester screening using nuchal translucency and biomarkers is effective for screening. Chorionic villus sampling generally is performed at 10-12 weeks by either the transcervical or transabdominal approach. There are two methods of analysis; the direct method and the culture method. While the direct method may prevent maternal cell contamination, the culture method may be more representative of the true fetal karyotype. There is a concern for mosaicism which occurs in approximately 1% of cases, and mosaic results require genetic counseling and follow-up amniocentesis or fetal blood sampling. In terms of complications, procedure-related pregnancy loss rates may be the same as those for amniocentesis when undertaken in experienced centers. When the procedure is performed after 9 weeks gestation, the risk of limb reduction is not greater than the risk in the general population. At present, chorionic villus sampling is the gold standard method for early fetal karyotyping; however, we anticipate that improvements in noninvasive prenatal testing methods, such as cell free fetal DNA testing, will reduce the need for invasive procedures in the near future.

Objectives: This study aims to identify the factors associated with colorectal cancer screening behaviors. Methods: The nation-wide representative samples of 2,928 adults aged ${\geq}50$ years for colorectal cancer screening were derived from the fourth Korea National Health and Nutrition Examination Survey (KNHANES IV). This study investigated socio-demographic, health behavioral and contextual factors associated with colorectal cancer screening using descriptive statistics and multivariate logistic regression analysis. Results: In terms of socio-demographic factors, gender, age, marital status, occupation, monthly income, and resident region were significantly different between screening group and non-screening group. Among health behavioral and contextual factors, regular physical checkup, weight control, physical activity, smoking, drinking and having other cancers were significantly different. From the multivariate logistic regression analysis, marital status, education level, regular physical checkup and weight control were associated with colorectal cancer screening behavior. Conclusions: It is necessary to understand the importance of early detection and cancer screening. Appropriate health education and active promotion about the cancer screening should be developed based on the study findings in order to motivate people to have cancer screening. Also, these findings should be reflected in the health policy.

This study was conducted to determine the use of screening for stomach, liver, colorectal, breast, and cervical cancers, which are included in the Korean National Cancer Screening Programme. In 2011 the National Cancer Centre in Korea conducted a nationwide, population-based, cross-sectional interview survey using multi-stage random sampling. Participants included 4,100 cancer-free men 40 years and over of age and women over 30 years of age. The lifetime screening rates for stomach, liver, colorectal, breast, and cervical cancers were 76.2%, 54.3%, 56.1%, 79.0%, and, 74.8%, respectively. The rates of recommended screening for stomach, liver, colorectal, breast, and cervical cancers were 64.6%, 22.9%, 35.3%, 60.4%, and 62.4%, respectively. More than 70% of all screening was attributed to organised cancer screening programmes. The main reason given for non attendance was 'no symptoms'. A greater effort is needed to increase screening rates, especially for liver and colorectal cancers.

배경 및 목적: 우리나라에서는 위암 검진을 수행하고 있으며, 조기위암의 비중이 증가되고 있으나, 위암 검진 지침에 따른 구체적인 효과에 대해서는 많은 보고는 없다. 이에 최근 위암 검진의 현황과 조기위암과 진행성 위암의 년도별 발생률 변화의 추이 등 여러 검진관련 자료 분석을 통한 국가 위암 검진의 효과에 대하여 알아보고자 본 연구를 진행하였다. 방법: 본 연구는 2009년부터 2015년까지 위암, 조기위암, 진행성 위암 그리고 그 외로 청구된 이력들을 조사하였다. KCD-6 코드가 2011년부터 적용되었으며, 질병청구 시 상병 코드가 KCD-6로 개정되면서 위암을 조기위암과 진행성 위암으로 코드를 세분화하였다. 국가건강검진에서 40세 이상 대상자에 대해 2년에 한 번씩 시행되는 위암 검사에 대한 효율성 평가를 위해 위암으로 등록되기 이전에 검진 경험 유, 무에 대한 분석을 진행하였으며 또한 위암 검진의 효과에 대해 성별로 구분지어 분석하였다. 결과: 2009-2015년 위암으로 등록된 환자 중 이전에 위암 검진 경험이 있었던 대상자가 전체 위암 대상자 중 74%로 검진 무경험자에 비해 월등히 높았다. 그 중 검진 이후 1년 이내에 위암으로 진단된 사람이 28.8%, 2년 이내 15.5%를 차지하였다. 암 진단 당시에 위암 진행 정도를 확인해 본 결과 검진 이후 1년 이내 발생한 경우, 조기위암은 21.1%, 진행성 위암 14.6% 로 나타났고, 검진 이후 2년 이내 조기위암은 31.5%, 진행성 위암 17.5%로 나타났다. 검진 무경험자들의 암 유형별 발생 현황을 보면 같은 기간 검진 경험자에 비해 조기위암은 15.1%, 진행성 위암은 25.3%로 진행성 위암의 비율이 높았다. 성별에 따른 분석 결과, 남자의 경우 검진을 통해 암 발생을 확인한 경우가 76% 여자의 경우 암 발생을 확인한 경우가 70.2%로 나타났다. 남녀 모두에서 검진 경험자가 검진 무경험자에 비해 조기위암으로 진단되는 비율이 높았다. 결론: 최근 위암 국가검진 자료가 포함된 이번 분석을 통하여 위암 검진의 병기 이전 효과를 확인할 수 있었다. 그러나 2년 이내 위암 검진 음성인 군에서 양성으로 진단된 환자가 상대적으로 적지 않았다. 따라서 위암 검진의 효과와 위해를 평가하고, 위암 검진의 질을 향상시키기 위한 더 많은 관련 연구가 필요하다.

Background and Objectives： The introduction of highly sensitive imaging techniques has made it possible to detect many non-palpable nodules, or“incidentaloma”in the thyroid. Discovery of these lesions raises concerns about their malignancy, but the optimal strategy for managing these lesions has not been clearly established. This study was designed to evaluate the usefulness of ultrasonographic exam with new diagnostic criteria and presume the value of mass screening for thyroid cancer. Materials and Methods : Mass screening for thyroid cancer were carried out in conjunction with mass screening for breast cancer. The subjects were 630 women aged 30 years or over. Thyroid glands were examined with 10 MHz transducer ultrasonography by one radiologist. Needle aspiration biopsy were performed when suspicious of malignancy under the new diagnostic criteria. Results and Conclusion : The new ultrasonographic criteria to diagnose thyroid cancer provided useful information and ensured more accurate evaluation. 7 cases of thyroid cancer were discovered and successfully managed. It should be further demonstrated that there is sufficient value of mass screening for thyroid cancer to perform it independently despite early cancer detection.

The US National Lung Screening Trial (NLST) demonstrated a 20% reduction in lung cancer mortality and a 6.7% decrease in all-cause mortality. The NLST is the only trial showing positive results in a high-risk population, such as in patients with old age and heavy ever smokers. Lung cancer screening using a low-dose chest computed tomography might be beneficial for the high-risk group. However, there may also be potential adverse outcomes in terms of over diagnosis, bias and cost-effectiveness. Until now, lung cancer screening remains controversial. In this review, we wish to discuss the evolution of lung cancer screening and summarize existing evidences and recommendations.

To an increasing extent, case-control studies are being undertaken to determine if use of early detection procedures is associated with reduced mortality from cancer. The authors recommend that in such studies the analysis focus on screening activity in cases that occurs during an interval prior to diagnosis in which the cancer is believed to be detectable and still curable and to a corresponding time period in controls. This approach places a heavy burden on the investigator to estimate accurately the period during which the tumor ought to be detectable using the test in question and to sort out reliably tests done in response to signs or symptoms of the cancer from screening tests per se. Nonetheless, the authors feel that it offers the greatest ability to discern a true benefit of screening, while minimizing the numerous potential biases that can be present in this type of study.

The announcement of the US Environmental Protection Agency that it will stop conducting or funding experimental studies on mammals by 2035 should prioritize ongoing efforts to develop and use alternative toxicity screening methods to animal testing. Toxicity screening is likely to be further developed considering the combination of human-induced pluripotent-stem-cell-derived organ-on-a-chip and multielectrode array (MEA) technologies. We briefly review the current status of MEA technology and MEA-based neuropharmacological drug screening using various cellular model systems. Highlighting the coronavirus disease pandemic, we shortly comment on the importance of early prediction of toxicity by applying artificial intelligence to the development of rapid screening methods.
