 Purpose : Since 2004 , the National Cancer Screening Program of Korea has included colorectal cancer screening based on primary screening with the fecal occult blood test ( FOBT ) . We report on the clinical features of colorectal cancer detected by the National Cancer Screening Program . 
 Methods : We retrospectively analyzed 577 patients who underwent elective surgery for colorectal cancer at the Seoul National University Hospital between January 2008 and December 2009 . We compared the clinical features of colorectal cancers detected by the National Cancer Screening Program ( NCSP group ) with those of the control group in terms of age , gender , preoperative symptom , location of the tumor , surgical technique and tumor - node - metastasis ( TNM ) stage . 
 Conclusion : Our study demonstrates the FOBT in the NCSP is effective in early detection of colorectal cancer .
