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.

Gastric cancer has been consistently decreasing worldwide, whereas cardia gastric cancer is on the rise. This indicates that the exposure rates to epidemiological causes are changing.In this study, we aim to review the risk factors for gastric cancer with respect to cardia and non-cardia types. One of the most significant risk factors for gastric cancer is Helicobacter pylori infection. H. pylori infection is known as a risk factor for non-cardia gastric cancer, and there have been results indicating that H. pylori infection is not associated with cardia gastric cancer. However, in the East Asian region, there is epidemiological evidence suggesting that H. pylori infection might be a risk factor for cardia gastric cancer. Smoking and alcohol consumption are known risk factors for gastric cancer, regardless of anatomical location.Obesity is considered a factor in the development of cardia gastric cancer. However, further research is needed to understand the specific relationship with non-cardia gastric cancer.The consumption of high-salt and processed meat is more distinctly associated with noncardia gastric cancer than in cardia gastric cancer. In addition to these factors, exposure to chemicals and radiation are considered risk factors for gastric cancer. Primary prevention of gastric cancer involves eliminating or avoiding risk factors such as H. pylori eradication and adopting a healthy lifestyle, including quitting smoking, reducing alcohol consumption, maintaining a healthy weight, and having a low-salt diet.

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) occasionally fails due to surgically altered anatomy, difficult cannulation, or poor general condition. This study evaluated the safety and effectiveness of percutaneous transhepatic papillary balloon dilatation (PTPBD) for managing extrahepatic bile duct stones. METHODS: Between 2001 and 2010, 17 out of 509 patients with extrahepatic bile duct stones and acute cholangitis were enrolled retrospectively. After PTPBD of the sphincter, the stones were extracted using an occlusion balloon to push the stone over a guidewire into the duodenum. The procedure success was evaluated based on residual stones. In addition, the size and number of stones and complications were analyzed. RESULTS: Of the 17 patients, nine had a previous gastrectomy, four had poor general condition, and four had unsuccessful cannulation. The stone diameter ranged from 8 to 25 mm. Seven, five, and five patients had one, two, or three or more stones, respectively. The results were successful in 16 out of 17 patients, with no residual stones. Treatment failed in one patient, who was then treated with the rendezvous technique with endoscopy. No procedure-related major complication occurred. Three patients had mild transient elevations of the serum amylase levels. CONCLUSIONS: PTPBD was safe and effective for managing extrahepatic bile duct stones in patients with unsuccessful or contraindicated ERCP.

OBJECTIVES: This study was conducted to investigate the systematic error, such as seasonal change or inadequate food items, in a food frequency questionnaire administered to workers in a Nuclear Power Plant, Korea. METHODS: We performed three repeat-tests with 28 subjects on May 13, July 8 and Dec 16, 1992. Our food frequency questionnaire (FFQ) comprised 84 foods organized into 7 food-groups, and was composed of the items of usual intake frequency (8 categories) and the amount per intake (3 or 4 categories) over the previous year. We compared the means of intake frequency and the frequency of the portion-size according to each season using Repeated Measures ANOVA and Pearson's chisquare test with Fisher's exact test. RESULTS: We found the significant seasonal changes of several food items in intake frequency measurement. These items were typical seasonal foods such as mandarin orange, plum and green vegetables, while the single questions consisted of inadequate food items such as thick beef or similar soup and various kimchi products. Significant seasonal changes in portion-size were found in only two items: cooked rice-brown and fresh.frozen fishes. CONCLUSIONS: The systematic errors observed could caused loss of validity in the FFQ. Consideration should be given for seasonal variation in FFQ survey and methodological concerns are needed to improve the quality for measuring usual diet pattern.
