Background: The cancer incidence and mortality are continued to rise worldwide. Regional cancer epidemiology in Korea including Gyeongsangnam-do is very important for prevention of cancer. It has been reported that cancer incidence is different depending on whether the region is rural or urban. Korea cancer registration program was performed since 2008, but data were not analyzed based on population. Methods: We retrospectively reviewed the data of cancer registration program of Gyeongnam regional cancer center between 2008~2011. We analyzed age-standardized rates cancer incidence by the population of the region, according to whether the region is rural or urban. The region where total population more than 200,000 people was defined as urban areas. Results: In 2011, thyroid cancer was the most common cancer in Korea. The incidence was higher in megalopolis such as Seoul, Gyeonggi-do than the other area with small population such as Gyeongsangnam-do. But, gastric cancer was more distributed in Gyeongsangnam-do, Jeollanam-do, and Jeollabuk-do, where rural area is more distributed than other regions. In Gyeongsangnam-do, the regions with less than 200,000 population have lower incidence of thyroid cancer and relatively high incidence of gastric cancer and lung cancer than do other big cities. The incidence of hepatobiliary cancer which was not popular in Korea, was markedly higher in Gyeongsangnam-do and Gyeongsangbuk-do. It is caused by high infection rate of Clonorchis sinensis along Nakdong-river. Conclusions: We studied the differences of regional cancer incidence and discuss causes of differences. Thyroid cancer incidence was much higher in the region which was more urbanization, in contrast gastric cancer and lung cancer incidence were relatively higher in rural area. Individualized plan for cancer prevention by regional characteristics is needed.
