“…Therefore, early detection and treatment is an important way for reducing death from gastric cancer (Leung et al, 2008;Lee et al, 2012). Regular screening reduces long-term cancer mortality (Smith et al, 2011) and a similar improvement in prognosis has been reported for gastric cancer (Mori et al, 2001). In Korea, a nationwide gastric cancer screening program was started in 1999 as part of the National Cancer Screening Program (NCSP) (Kim et al, 2011).…”

Objectives: Despite government efforts to increase participation in gastric cancer screening, the rate is still suboptimal in Korea. Therefore, we explored barriers to and predictors of gastric cancer screening participation among a nationally representative sample. Methods: We used the Health Interview Survey sub-dataset derived from the Fourth Korean National Health and Nutrition Examination Survey 2008 (KNHANES IV) to evaluate participation in gastric cancer screening and factors associated with attendance in individuals age ≥40 years. We enrolled 4,464 subjects who completed the questionnaire and were not previously diagnosed with gastric cancer. Four groups of factors were considered potential predictors of gastric cancer screening in a multivariate analysis: sociodemographic, health behavior, psychological and cognitive, and dietary factors. Results: Overall, 41.3% complied with the gastric cancer screening recommendations. Younger age, lower education level, living without a spouse, frequent binge drinker, and current smoker were significantly associated with less participation in gastric cancer screening. Conclusions: To improve participation in gastric cancer screening, more focused interventions should be directed to vulnerable populations, such as groups with low socioeconomic status or unhealthy behavior. In addition, there should be new promotional campaigns and health education to provide information targeting these vulnerable populations.

“…Regular screening has been shown to reduce long-term cancer mortality, (16,17) and a similar reduction or improvement of the prognosis for survival has been reported for GC. (9,18) Despite the importance of having routine cancer screening at the recommended intervals, there have been no published studies that have examined how many people attend repeat GC screening. An important goal of screening programs is not only to achieve high participation rates for the screening programs, but also to maintain these high rates at each subsequent round of screening.…”

Who participates in the gastric cancer screening and on‐time rescreening in the National Cancer Screening Program? A population‐based study in Korea

Gastric cancer (GC) screening is a major challenge in countries where the disease is highly prevalent. This study was conducted to identify the factors associated with participation in GC screening and on-time rescreening among the average-risk population in Korea. The study population was derived from the National Cancer Screening Program database. The population for this study was 22 913 618 individuals aged ‡40 years who had been invited to participate in a GC screening program from 2005 to 2006. We determined whether these individuals had attended the GC screening program and which method -an upper gastrointestinal series (UGIS) or endoscopy-they underwent. We followed the participants to determine whether they had a second GC screening after 2 years. The overall participation rate in the GC screening was 20.5%. More people underwent UGIS than endoscopy. Individuals who had been screened by endoscopy rather than UGIS were more likely to be younger, male, or those who were National Health Insurance (NHI) beneficiaries with a higher premium rate. Of those who underwent baseline screening, 59.4% participated in a rescreening program 2 years later. NHI beneficiaries with a higher premium rate were significantly more likely to be rescreened than medical aid recipients. The results from this study showed that the UGIS were more commonly used in organized GC screenings in Korea, and those who underwent UGIS were more likely to return for subsequent screening compared to those who underwent an endoscopy. (Cancer Sci 2011; 102: 2241-2247 G astric cancer (GC) is the fourth most common cancer behind lung cancer, breast cancer, and colorectal cancer, and in 2008 was the second most common cause of cancer deaths worldwide. (1) In Korea, GC is the most frequent type of cancer. (2,3) In countries where GC is highly prevalent, GC screening is offered to the average-risk population to reduce the disease burden. (4) Gastric cancer screening has shown improvements in survival rates as a result of early detection and consequently higher cure rates. (5) Therefore, many Asian countries with a high burden of GC have considered implementing GC screening for the general population. (6) Since 1960, Japan has implemented photofluorography (via an indirect upper gastrointestinal series [UGIS]) screening programs to detect GC in its early stages and prevent GC deaths. (6) The cohort studies conducted in Japan showed a significant GC mortality reduction with photofluorography screening. (5,7) In recent years, endoscopy has replaced photofluorography as the initial mass screening method in several cities in Japan. (8,9) This technique is increasingly useful for GC screening because of its high detection rate. In a study conducted in Niigata, Japan, the detection of GC by endoscopy was 2.7-4.6 times higher than that by direct or indirect UGIS. (10)(11)(12) Recently, Hosokawa et al. (13) reported an approximately 65% reduction in the GC death rate for participants screened with endoscopy. Despite this promising result, direct evidence for t...

“…A study conducted in 1995 showed that screening tests should be performed at 3-year intervals for protective purposes [14]. In 2001, Mori et al [15] recommended a screening interval of 2 years. However, neither of these studies used survival outcome to define the optimum screening interval.…”

Background/Aims: Early gastric cancer (EGC) can be treated by endoscopic resection, which results in an excellent prognosis. Optimal screening intervals considering risk factors for gastric cancer have not been established. The aim of this study was to determine the maximum gastric cancer screening interval in terms of long-term survival. Methods: Curative resection was performed in 561 patients with gastric cancer who had completed a questionnaire on their previous history of screening tests and risk factors. The association between EGC detection rate and previous screening history was evaluated, and 5-year disease-free survival rates were compared between various screening intervals. Results: Multivariate analysis showed that intestinal metaplasia [hazard ratio (HR) 9.690, 95% confidence interval (CI) 5.896–15.927] and previous screening history (HR 0.077, 95% CI 0.048–0.125) were independent factors associated with advanced gastric cancer. In patients without intestinal metaplasia, there was no significant difference in the extent of gastric cancer progression and the 5-year disease-free survival rate between groups with screening intervals of less than 3 years. In patients with intestinal metaplasia, the cutoff screening interval for detection of EGC and disease-free survival was 2 years. Conclusion: The optimum screening interval for disease-free survival for gastric cancer in a normal population is 3 years, but a screening interval of 2 years should be used for patients with intestinal metaplasia in Korea.
