ABSTRACT
Objective To observe the curative effect of laparoscopic and open radical gastrectomy for gastric cancer patients and the impact on patients' CD4+CD25+T cells, oxidative stress, IL-2 and soluble receptors. Methods 120 cases from November 2009 to September 2012 were enrolled. 60 patients received laparascopic radical gastrectomy (LRG group) and 60 patients received open radical gastrectomy (ORG group) as research object, the two kinds of operation mode were compared and the impact of operation on patients' CD4+cells, oxidative stress, CD25+T IL-2 and its soluble receptor were recorded. Results The operation time, blood loss, number of lymph node dissection n LRG group were (285.8 ± 98.6), (343.3 ± 125.5), (7.8 ± 1.2), all the indexes were significantly superior to the ORG group and LRG group of patients with anastomotic leakage, intestinal obstruction, bile duct injury and pulmonary infection were 1, 1, 0, and 0 cases no difference in ORG group than MDA and AOPP, after the operation were increased, but the LRG group was lower than that of ORG group patients; postoperative antioxidant GSH-PX, SOD decreased, but LRG was higher than that of ORG group, and LRG group after treatment increased CD4+CD25+T cells in patients with the content of IL-2 of two groups after treatment, s-IL-2R increased than before LRG, group IL-2, s-IL-2R levels were (32.6 ± 4.2) and (23.6 ± 4.6) μg/ml was significantly lower than that of ORG group, P < 0.05, There was no difference in the 1, 2, 3, and 5 year survival rates between the two groups of patients. Conclusion Laparoscopic and open surgery for gastric cancer is equivalent, but also help to stabilize T cells, inhibit oxidative stress and inflammatory factors.
