    PurposeSurgical site infection (SSI) is a frequent complication of elective surgery for colorectal cancer. The classical clinical markers of infection-elevations in white blood cell count, C-reactive protein (CRP) level, and body temperature-do not precisely predict SSI after elective colorectal resection. The objective of this study was to evaluate the efficacy of procalcitonin (PCT) as a tool for diagnosis of SSI in elective surgery for colorectal cancer.MethodsA total of 114 consecutive patients undergoing elective colorectal resection for cancer were evaluated. Routine blood samples, for determining PCT level, CRP plasma concentration, and white blood cell count, were obtained on postoperative days (POD) 1 and 3. Predictive values for each of the laboratory markers were examined.ResultsSSI was diagnosed in 18 (15.7 %) of 114 patients. Patients with SSI exhibited significantly higher PCT levels (on PODs 1 and 3) and CRP levels (on POD 3) than did patients without SSI. According to receiver operating characteristic analysis, PCT showed the highest area under the curve (AUC) for predicting SSI on both PODs 1 and 3 (AUC, 0.76 and 0.77, respectively). Multivariate logistic regression analysis showed that PCT (on PODs 1 and 3) was an independent predictor for SSI (odds ratio = 14.41 and 9.79, respectively).ConclusionSerum PCT is more reliable laboratory marker for the early diagnosis of SSI after elective colorectal cancer surgery, compared with conventional inflammatory indicators. PCT could serve as an additional diagnostic tool for the early identification of SSI to improve clinical decision making.
