Brief Summary:
This study aimed to clarify existence of immunological benefit of laparoscopic colon cancer surgery compared to open colon surgery.

Condition or disease
Immunity

Detailed Description:
Patients with clinical stage Ⅲ left colon and upper rectal cancer were prospectively assigned to undergo LC (n=35) or OC (n=39). Factors related to cellular immunity of host (total lymphocyte count, CD4 lymphocyte, CD8 lymphocyte, CD4/CD8 ratio, HLA-DR expression on monocyte (mHLA-DR)) were examined preoperatively, on the 1st day of operation (POD1) and the 5th day of operation (POD5).

Study Type : Observational
Actual Enrollment : 84 participants
Observational Model: Case Control
Time Perspective: Prospective
Official Title: Prospective Comparative Study of Immunological Benefit Between Laparoscopic Colectomy and Open Colectomy
Study Start Date : January 2006
Primary Completion Date : November 2007
Study Completion Date : November 2007

Group/Cohort
OC
Open colorectal resection
LC
Laparoscopic colorectal resection



Primary Outcome Measures :
  1. Immune factors [ Time Frame: post OP 5th day ]

Secondary Outcome Measures :
  1. Post-operative complications [ Time Frame: POD 7th days ]
