This study was conducted to demonstrate the epidemiology of colorectal cancer (CRC) in Korea using the by analysis of big data using the Korean National Health Insurance Service (NHIS).


We analyzed the NHIS database of patients admitted hospitals which received its quality assessment of CRC between 2011 and 2014.


We included 71,513 colorectal cancer patients. Median follow-up duration was 3.2 years (range 0.003-5.5 years). Male patients were 60.1% and median age was 65 years old (interqurtile range 56-73). The stage at diagnosis was stage I in 22.0%, stage II 29.0%, stage III 35.6%, stage IV 12.9%. As primary site according to surgery code, colon is 61.7% and rectum is 38.3%. Patients with adenocarcinoma were 96.5%. Survival probability at 5 year elderly patients (³ 70 years old) showed worse survival rate than that of patient with age


These results show epidemiology and survival of CRC in Korea. Our study was the first to describe these data for colorectal cancer at a nationwide level.
