Hypothesis of this study is that increased immunity of primary tumor affects the increased number of lymph node retrieved. This study investigates whether immunity-related cytokine expression on primary tumor, colonic mucosa, and serum is associated with the number of lymph node retrieved in colorectal cancer patients.

Primary Outcome Measures:
  • Association between immune related cytokine and number of lymph nodes retrieved. [ Time Frame: 2 months after surgery ] [ Designated as safety issue: No ]
    Immunity related cytokine - IL-12, IFN-r, GM-CSF, IL-4, TNF-a, IL-6, IL-8, IL-10, TGF-b1, CXCR4, SDF1, HGF, VEGF - expression is assessed using Bioplex assay. Patient serum is taken one day before surgery. Primary tumor and colonic mucosal tissue are taken just after surgery. Bioplex assay is performed after patients' enrollment

Biospecimen Retention:   Samples Without DNA

Serum and postoperative specimen
