Trends in Gastric Cancer Incidence According to the Clinicopathological Characteristics in Korea, 1999-2014 / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: The aim of this study was to evaluate recent trends in gastric cancer incidence according to the age, sex, and tumor location in the Korean population. MATERIALS AND METHODS: Using data from the Korea Central Cancer Registry between 1999 and 2014, gastric cancer incidence, annual percent changes, and male-to-female incidence rate ratios (IRRs) according to tumorlocationwere determined. The distribution of disease extent according to the tumor location and its changes between 2006 and 2014 were also analyzed. RESULTS: Incidence of gastric cancer was stable until 2011 and decreased between 2011 and 2014. The age-standardized incidence rate of gastric cancer was 43.6 (per 100,000) in 1999 and 35.8 in 2014. The proportion of cardia/fundus cancer remained stable (5.9% to 7.1%), and that of body cancer increased (35.3% to 43.2%). The male-to-female IRR decreased in most age groups, except for those in their 60s. In the distribution of disease extent, the proportion of localized disease increased, and regional and distant disease decreased in all tumor locations (53.9% to 66.0%, 31.4% to 22.5%, and 14.8% to 11.5%, respectively; p < 0.001). For histological type, the proportion of carcinoid tumor and non-epithelial tumor increased (0.3% to 1.0%, and 0.8% to 1.4%, respectively). CONCLUSION: In the 15 years from 1999 through 2014, age-standardized incidence of gastric cancer started to decrease from 2012, and the proportion of cardia/fundus cancer remained unchanged. The trend of increasing localized cancer was observed in all tumor locations.

The Global Developments in Transfusion Replacements and Patient Blood Management / 대한수혈학회지

Blood transfusions were once believed to the most potent and cost-effective method of improving patients' survival outcomes, but accumulating evidence over the past thirty years strongly suggests allogeneic transfusions as independent prognosticators of complications, prolonged hospital stay, and higher costs. A growing body of health care providers in Korea and throughout the world recognize a causal relationship between these adverse outcomes with liberal transfusion policies and call for a universal paradigm shift regarding the management of blood. Currently, the most promising contender is Patient Blood Management (PBM), which has been found to improve patient outcomes by conserving or optimizing the patient's own blood and physiologic reserves and advocating for restrictive transfusion policies. PBM incorporates evidence-based transfusion replacements to address anemia, bleeding, and blood disorders. These various methods–such as intravenous iron, erythropoiesis stimulating agents, coagulating factors, and topical hemostatic agents–are gaining recognition because of their ability to preclude the need for allogenic transfusions while effectively managing the patient's blood.
