Among 1,526 cases performed gastrofiberscopy, 141 patients of upper gastrointestinal bleeding who were admitted to the Department of Internal Medicine, St. Marys Hospital of Catholic Kfedical College during the past 2 years 2 and 6 months from March l, 1974 to September 6,. 1976 were clinically observed. The results were as follows: 1. The incidence of upper gastrointestinal bleeding among 1,526 cases performed gastrofiber copy was 9.2%. The sex distribution was 114 in male and 27 in female with a mean age of 4b. The ratio of male to female was 4. 2: 1. 2. The sources of bleeding were gastric ulcer (27.7%), duodenal ulcer (17.7%), gastric carcnoima (17%) rupture of esophageal varices (13.5%), erosive gastritis (12. 1%), gastroducdenitis (3.5%), miscel Janeous (5.7%), and unknown origin (2.1%) in order. 3. The endoscopic accuracy in patients with upper gastrointestinal bleeding was gastric ulcer CG9. 2%3, gastric carcinoma (96.0%), erosive gastritis (88.2%) 3, and duodenal ulcer, gastroauodenitis, and rupture of esophageal varices were 100%. 4. The success rates in identifving the site of bleeding in relation to time of endoscopy after upper gastrointestinal bleeding were 63.2% within 24 houss, 47.1% in 24-48 hours, 17.6% in 48 72 hours, and 6.3% after 7 days. The success rate fell with increasing time after upper gastrointestinal bleeding. 5. The presence of more than one source of upper gastrointestinal bleeding site was found much in cur patients. The early endoscopy was more reliable than radiology for determining the origin of upper gastrointestinal bleeding, and multiple lesions were found only by endoscopic examination. 6. Complication of endoscopy for the diagnosis of upper gastrointestinal bleeding was 2 out of 141 cases (l.4%) one was arterial bleeding from the lesion of gastric biopsy and the other was aggravation of gastric ulcer bleeding. Both of these was reversible.

Purpose Although the cancer stage at diagnosis is the most important prognostic factor for patients’ survival, there are few population-based estimates of stage-specific survival outcome, especially in Asian countries. Our study aims to estimate stage-specific survival for Korean patients. Materials and Methods We analyzed the Korea National Cancer Incidence Database data on 626,506 adult patients aged ≥ 20 years, who were diagnosed between 2006 and 2010 with stomach,colorectal, liver, lung, breast, cervix, prostate, and thyroid cancers. Patients were followed up to December 2011, and the 5-year relative survival rates (RSRs) were calculated for gender and age group by Surveillance, Epidemiology, and End Results (SEER) stage at diagnosis. Results The 5-year RSRs for all localized-stage cancers, except for lung and liver, exceeded 90% with that for thyroid cancer being the highest at 100.4%. These values for distant stage liver, lung, and stomach cancers were very dismal at 2.5%, 4.8%, and 5.5%,respectively, while it was 69.1% for thyroid cancer, and was in the range of 18.3-36.4% for colorectal, cervix, breast and prostate cancers. Overall, the 5-year RSRs for all cancer types decreased with aging across all the disease stages with exception of prostate cancer, which suggests biologic difference in these cancer types in a young age group. When compared with US SEER data, Korean patients had better stagespecific survival rates for stomach, colorectal, liver, and cervical cancers. Conclusion Korean cancer patients showed relatively favorable stage distribution and 5-year RSRs, which suggests potential contribution of the national cancer screening program.

Cancer Statistics in Korea: Incidence, Mortality, Survival, and Prevalence in 2016
정규원,원영주,공현주,이은숙 대한암학회 2019 Cancer Research and Treatment Vol.51 No.2
Purpose This study presents the 2016 nationwide cancer statistics in Korea, including cancer incidence, survival, prevalence, and mortality. Materials and Methods Cancer incidence data from 1999 to 2016 were obtained from the Korea National Cancer Incidence Database and followed until December 31, 2017. Mortality data from 1983 to 2016 were obtained from Statistics Korea. The prevalence was defined as the number of cancer patients alive on January 1, 2017 among all cancer patients diagnosed since 1999. Crude and age-standardized rates (ASRs) for incidence, mortality, and prevalence and 5-year relative survivals were also calculated. Results Overall, 229,180 and 78,194 Koreans were newly diagnosed and died from cancer in 2016, respectively. The ASRs for cancer incidence and mortality in 2016 were 269.0 and 79.8 per 100,000 individuals, respectively. The all-cancer incidence rate increased significantly by 3.6% annually from 1999 to 2011 and started to decrease after 2011 (2011-2016; annual percent change, –3.1%). However, overall cancer mortality has decreased 2.7% annually since 2002. The 5-year relative survival rate for patients diagnosed with cancer between 2012 and 2016 was 70.6%, an improvement from the 41.2% for patients diagnosed between 1993 and 1995. Conclusion The cancer prevalence in Korea has increased very fast as survival has improved remarkably. The high prevalence of cancer emphasizes the need for comprehensive cancer control efforts in Korea.

Cancer Statistics in Korea: Incidence, Mortality and Survival in 2005
정규원,박소희,공현주,성주헌,신혜림,이진수,원영주,박은철 대한의학회 2009 Journal of Korean medical science Vol.24 No.6
Cancer has been the most common cause of death in Korea since 1983 and is a major public health concern. This paper overviews the nationwide cancer statistics, including incidence, mortality, and survival rates, and their trends in Korea. In 2005, 142,610 new cancer cases and 65,117 cancer deaths occurred in Korea. The incidence rate for all cancer combined increased by 2.6% annually from 1999 to 2005. Significant increases have occurred in the incidence of colorectal, thyroid, female breast, and prostate cancers. The number of cancer deaths has increased over the past two decades, due mostly to population aging, while the age-standardized mortality rates have decreased in both men and women since 2002. Notable improvement has been observed in the 5-yr relative survival rates for most major cancers and for all cancer combined, with the exception of pancreatic cancer. The nationwide cancer statistics in this paper will provide essential data for evidence-based decisions in the national cancer control program in Korea.
