Stomach cancer is the most common cancer in Korea. Early detection through national stomach cancer screening program and improvements in treatment resulted better chances of survival. Thus, understanding both cancer and non-cancer mortality patterns experienced by patients are critical. In this study, we demonstrate how competing risks survival analysis based on the population-based cancer registry data can inform cancer survivorship issues. To access non-cancer health status, we further utilized Korean National Health Insurance Claims big data and analyzed comorbidity patterns in stomach cancer patients relative to the Korean general population matched with age, gender and geography. We carried out network analysis and data visualization to better understand comorbidity patterns. The results showed that death due to other causes become increasingly important in patients diagnosed as early stage stomach cancer and it exceeds cancer mortality approximately 5-8 years after cancer diagnosis. Study findings implies that early stage stomach cancer patients may require management of their chronic disease in their survivorship follows ups.
