Abstract

The aim of the present study was to measure adenosine triphosphate (ATP) levels in CD4+ T cells as a marker of T‑cell activity following surgery for colorectal cancer using the ImmuKnow assay kit. A total of 16 consecutive patients who underwent surgical resection for colorectal cancer between August and December, 2012 were enrolled in this study, of whom 7 underwent laparoscopic resection and 9 underwent open abdominal surgery. The intracellular ATP levels in CD4+ T‑lymphocytes were measured using the ImmuKnow assay kit preoperatively and on the 1st, 4th and 8th postoperative days, as were the white blood cell (WBC) count, lymphocyte count and C‑reactive protein (CRP) levels. The ATP level of the CD4+ T‑cells was significantly elevated on the 1st day following surgery compared to the preoperative level (P<0.01) and gradually returned to preoperative levels; the lymphocyte count was significantly decreased on the 1st postoperative day (P<0.001). In addition, the ImmuKnow assay demonstrated that only the ATP level, but not the WBC count, lymphocyte count or CRP level, exhibited a significant difference on the 1st (P=0.080) and 8th (P=0.042) postoperative days between the laparoscopic and open abdominal surgery groups. In conclusion, the ATP level of CD4+ T‑lymphocytes was increased in response to surgical stress, in tandem with a decrease in the lymphocyte count. Therefore, the ImmuKnow assay kit may be clinically applicable for monitoring the immune response following surgery, as it exhibits a higher sensitivity compared to other assays.
