Open colorectal resection
Laparoscopic colorectal resection

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).
