Yonsei University
  Purpose
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.

Condition
Colorectal Cancer

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Cross-Sectional

Primary Outcome Measures:
  • Association between immune related cytokine and number of lymph nodes retrieved. [ Time Frame: 2 months after surgery ]
    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

Enrollment: 25
Study Start Date: June 2012
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts
Colorectal cancer patients
Colorectal cancer patients undergoing elective colorectal resection
