The crude incidence rate of stomach cancer in Chuncheon-si during 2000-2002 / 대한내과학회지

ABSTRACT

BACKGROUND: Stomach cancer is the most common cancer in Korea, and it can be easily diagnosed by performing endoscopy. Helicobacter pylori (H. pylori) is associated with stomach cancer, and there has been much recent interest in the epidemiology of stomach cancer. Therefore, we estimated the incidence of stomach cancer in Chuncheon-si during 2000-2002. METHODS: From July 1st, 2000 through June 30th, 2002, we investigated the subjects who were confined to be newly diagnosed cases living in Chuncheon-si. The data was collected from the medical records from all the medical facilities located in Chuncheon-si. RESULTS: The total number of cases of newly diagnosed stomach cancer during this period (2000-2002) was 186 (117 males and 69 females). The annual crude incidence rate of stomach cancer was estimated to be 37.0 per 100,000 persons overall, and 47.0 and 27.2 in the males and females, respectively. The annual age standardized incidence rate for the Korean population was 33.7 per 100,000 persons overall, and 42.2 and 25.1 for the males and females, respectively. The major symptoms of stomach cancer patients were epigastric pain (61.8%) and weight loss (31.2%). The proportion of early gastric cancer was 34.9% (60 among 172 persons) of the cases of stomach cancer. 64 patients (74%) were H. pylori positive. CONCLUSIONS: We report here on the estimated incidence rate of the stomach cancer and the characteristics of the stomach cancer patients in Chuncheon-si during 2000-2002. This study has generated basic epidemiologic data to identify the effect of H. pylori eradication on the future incidence rate of stomach cancer.
