Abstract
Changes in expression levels of serum interleukin-4 (IL-4), IL-10 and adiponectin (APN) in patients with postoperative infection of colorectal cancer were studied. The clinical data of 159 patients receiving radical surgery for colorectal cancer in Xiangyang No. 1 People's Hospital, Hubei University of Medicine from January 2014 to December 2017, were retrospectively analyzed. A total of 67 patients with postoperative infection were enrolled into the infection group, while the remaining 92 patients without infection were enrolled into the non-infection group. The expression levels of serum IL-4, IL-10 and APN of patients were detected via enzyme-linked immunosorbent assay. The correlation of IL-4, IL-10 and APN levels with stage of colorectal cancer were explored by the Spearmans correlation analysis. The expression levels of IL-4 and IL-10 in the infection group were significantly higher than those in the non-infection group at day 3 after surgery (P<0.05). The expression level of APN in the infection group was lower than that in the non-infection group at day 3 after surgery (P<0.05). The serum IL-4 and IL-10 levels in pulmonary infection was higher and the serum IL-10 level in pulmonary infection was higher than those in incision infection and abdominal infection (P<0.05). The IL-4 and IL-10 levels in patients with colorectal cancer in the infection group at day 3 after surgery had a significant positive correlation with the stage of colorectal cancer (r=0.9357, P<0.001; r=0.9717, P<0.001), and the APN level in patients with colorectal cancer in the infection group at day 3 after surgery had a significant negative correlation with the stage of colorectal cancer (r=−0.9736, P<0.001). The serum IL-4 and IL-10 levels in patients with postoperative infection of colorectal cancer are positively correlated with the stage of cancer, while the serum APN level was negatively correlated with the stage of cancer.
