OBJECTIVETo evaluate the results of the active follow-up among registered cancer patients in 2002 - 2005 in urban areas of Beijing.
METHODSA number of 63 997 cancer patients diagnosed during 2002 - 2005 were selected from the surveillance database of Beijing Office for Cancer Prevention and Control. By matching the identity information of the patients with the death surveillance database built by the vital statistic department in Beijing, 29 223 patients were confirmed to be alive.1149 cases were removed from the study due to lack of exact key variables, such as address and telephone numbers. 28 074 patients were, at last, included in the active follow-up study. The investigators and the inspectors, who accepted standard training program, investigated each patient's status of census register and survival condition by phone calling, household interview and visits at local police station or residential committee. The loss ratio of follow-up and the constituent ratio of the withdrawal reasons were calculated.
RESULTSAmong the 28 074 patients selected in active follow-up, 21 696 patients were followed successfully; 1453 of whom didn't have the census register of Beijing, which accounted for 6.70%. Out of the other 20 243 Beijing residents, 4715 patients (23.29%) were already dead and 84.22% (3971/4715) of them replenished the failure to report by passive follow-up. Among all the 4715 dead cases, 4405 (93.43%) patients were died from cancer. The follow-up study helped to replenish the vital statistics in different districts, the ratio ranged from 4.87% and 8.85%. 6378 patients were withdrawn from the study. The loss ratio was 22.72% (6378/28 074), and the total loss ratio was 12.03% ((6378 + 1149)/(63 997 - 1453)). Of these withdrawal cases, 3041 (47.68%) were lost to follow-up in that the investigators can't find the patients or the relatives of the patients according to the registered phone number or address information. The other reasons included: the patients removed to other areas (1199 cases, 18.80%), the patients and their family members were temporarily not at home (127 cases, 1.99%), the patients and their family members rejected to answer the interview (292 cases, 4.58%), and other reasons (1719 cases, 26.95%).
CONCLUSIONThe method of active follow-up towards registered cancer patients can replenish the missing information which could not be collected from passive follow-up procedure; and therefore effectively improve the quality of data in cancer registration.

How the news media cover cancer may have profound significance for cancer prevention and control; however, little is known about the actual content of cancer news coverage in Korea. This research thus aimed to examine news portrayal of specific cancer types with respect to threat and efficacy, and to investigate whether news portrayal corresponds to actual cancer statistics. A content analysis of 1,138 cancer news stories was conducted, using a representative sample from 23 news outlets (television, newspapers, and other news media) in Korea over a 5-year period from 2008 to 2012. Cancer incidence and mortality rates were obtained from the Korean Statistical Information Service. Results suggest that threat was most prominent in news stories on pancreatic cancer (with 87% of the articles containing threat information with specific details), followed by liver (80%) and lung cancers (70%), and least in stomach cancer (41%). Efficacy information with details was conveyed most often in articles on colorectal (54%), skin (54%), and liver (50%) cancers, and least in thyroid cancer (17%). In terms of discrepancies between news portrayal and actual statistics, the threat of pancreatic and liver cancers was overreported, whereas the threat of stomach and prostate cancers was underreported. Efficacy information regarding cervical and colorectal cancers was overrepresented in the news relative to cancer statistics; efficacy of lung and thyroid cancers was underreported. Findings provide important implications for medical professionals to understand news information about particular cancers as a basis for public (mis)perception, and to communicate effectively about cancer risk with the public and patients.

4.Overview of Asbestos Issues in Korea.
Journal of Korean Medical Science 2009;24(3):363-367
Asbestos is a carcinogen that causes diseases such as mesothelioma and lung cancer in humans. There was a sharp increase in the use of asbestos in Korea in the 1970s as Korea's economy developed rapidly, and asbestos was only recently banned from use. Despite the ban of its use, previously applied asbestos still causes many problems. A series of asbestos-related events that recently occurred in Korea have caused the general public to become concerned about asbestos. Therefore, it is necessary to take proper action to deal with asbestos-related events, such as mass outbreaks of mesothelioma among residents who lived near asbestos textile factories or asbestos mines. Although there have been no rapid increases in asbestos-related illnesses in Korea to date, such illnesses are expected to increase greatly due to the amount of asbestos used and long latency period. Decreasing the asbestos exposure level to levels as low as possible is the most important step in preventing asbestos-related illnesses in the next few decades. However, there is a lack of specialized facilities for the analysis of asbestos and experts to diagnose and treat asbestos-related illnesses in Korea; therefore, national-level concern and support are required.

Although colorectal cancer emerged as a major public health concern, its incidence as well as mortality are decreasing during recent years in Korea. Most important contributor for these reduction in disease burden is colorectal cancer screening. Besides screening, primary prevention through risk factor modification could reduce 10% to 54% of colorectal cancer incidence. These factors include limiting alcohol, processed and red meat consumption, and cigarette smoking, maintaining optimal weight, and engaging physical activities.

The purpose of this study was to evaluate treatment patterns, outcome and prognosticators for patients with leptomeningeal metastases from solid tumor. Medical records of 80 patients from January 1, 2004 to May 31, 2011 were retrospectively reviewed. Most frequent site of origin was the lung (59%) followed by the breast (25%). Most patients were treated with intrathecal chemotherapy (90%) and/or whole brain radiotherapy (67.5%). Systemic therapy was offered to 27 patients (33.8%). Percentage of patients treated with single, dual, and triple modality were 32.5%, 43.8%, and 23.8%, respectively. Median survival was 2.7 months and 1 yr survival rate was 11.3%. Multivariate analysis showed that negative cerebrospinal fluid cytology, fewer chemotherapy regimen prior to leptomeningeal metastases, whole brain radiotherapy, systemic therapy, and combined modality treatment (median survival; single 1.4 vs. dual 2.8 vs. triple 8.3 months, P<0.001) had statistical significance on survival. Subgroup analysis of non-small cell lung cancer (NSCLC) patients showed that targeted therapy had significant independent impact on survival (median survival; 10.5 vs. 3.0 months, P=0.008). Unlike previous reports, survival of patients with NSCLC primary was comparable to breast primary. Furthermore, combined modality treatment for all patients and additionally targeted therapy for NSCLC patients should be considered in the treatment of leptomeningeal metastases from solid tumor.

Cancer is a leading cause of death around the world. Education is at the core of cancer prevention activities, especially programs targeting empowering existing public health workforce. In the past 10 years, researchers at the University of Pittsburgh have been building the Global Health Network Supercourse project, a library of over 4500 online lectures and a network of nearly 50000 public health professionals in 174 countries. As of November, 2010, the overall number of Supercourse participants from Asia exceeds 7000 participants. The Supercourse network has been investigating methods for Internet based recruitment of cancer prevention professionals in order to network cancer experts locally and globally, including the use of mHealth technologies for cancer research education and for NCD registries. Supercourse is a tool that can offer a solution to the challenges of information sharing, especially in the field of NCDs and cancer. In this paper, we highlight the need for the development of Cancer Supercourse with Satellite in Asia and encourage faculty members from Asia to join the network.

OBJECTIVETo describe the distribution changes of the mortality rate for cervical cancer in China between the 1970's and 1990's and provide the scientific evidence for the prevention and control strategies for cervical cancer campaign in China between next century.
METHODSData from two National Surveys for the Causes of Death in 1970's and 1990's in China. The crude and adjusted mortality rates for the cervical cancer and the distributions based on age and area were calculated and described. The comparison of the differences of changes between two mortality rates periods and together with its trends were shown based on the age-standardized.
RESULTSDuring two decades, the mortality rate for cervical cancer was 10.7 per 100,000 in 1970's which declined to 3.89 per 100,000 in 1990's, and from the 3rd ranking among all female malignant tumors to the 6th in 1990's (decreased about 63.64%). But the declination was not evenly. There have still been some high-risk areas, most located in rural countries in the mid-west of China, with rates remain unchanged and even at the highest level in the world, such as Wudu in Gansu and Yangcheng in Shanxi. A big difference was showed between rural country and city, but in both of them, the mortality rates in 1990's were significantly much lower than in 1970's (P = 0.001) at each five-year age group. And in the city, there was a much sharper increased trend in young women in 1990's.
CONCLUSIONSThe mortality rate for cervical cancer campaign in China has been substantially declined during past twenty years, but it's still a major health problem for women, especially in rural China. The focus of the prevention and control for the cervical cancer in the next century should put on rural areas, especially in mid-west of China and young women in the city.

10.Epidemiology of gastric cancer in Korea
Journal of the Korean Medical Association 2019;62(8):398-406
Rapid aging, economic development, lifestyle westernization, hygiene improvement, and scientific development have contributed for the epidemiologic changes of gastric cancer. This study aimed to review the descriptive epidemiology, risk factors, and prevention of gastric cancer in Korea. Age-standardized incidence and mortality of gastric cancer have decreased and showed age effect and cohort effect. Annual percent change in the incidence of gastric cancer has been prominent in recent years. Major risk factor of gastric cancer is Helicobacter pylori infection. Although H. pylori infection was associated with only non-cardia gastric cancer in meta-analysis, H. pylori infection was associated with both non-cardia and cardia gastric cancer in Asian studies. The estimated population attributable fraction of H. pylori regarding gastric cancer incidence was about 76% in Korean. Cigarette smoking and alcohol drinking was associated with gastric cancer regardless of cardia and non-cardia gastric cancer. Cigarette smoking was estimated to be responsible for 28% of gastric cancer incidence in men and 2% in women. Obesity was risk factor for cardia gastric cancer but not non-cardia gastric cancer. This discrepancy between cardia and non-cardia gastric cancer was consistently shown in epidemiologic studies in Korea. Salt intake was also well-known risk factor of gastric cancer and prevalence of high sodium intake more than 2,000mg in Korean was 81.5%. For primary prevention of gastric cancer, eradication of H. pylori and life-style modification including no smoking, no alcohol drinking, weight control, and low sodium intake are important. Gastric endoscopy is recommended for secondary prevention of gastric cancer.
