Background
Recently, a preoperative systemic inflammatory response has been reported to be a prognostic factor in patients with colorectal cancer (CRC). However, the prognostic significance of a systemic inflammatory response in the early stage after surgery in patients with CRC is unknown. The aim of this retrospective study was to evaluate the prognostic significance of a postoperative systemic inflammatory response in patients with CRC.
Methods
Two hundred and fifty-four patients who underwent potentially curative surgery for stage II/III CRC were enrolled in this study. Univariate and multivariate analyses were performed to evaluate the relationship between the prognosis and clinicopathological factors, including the neutrophil-to-lymphocyte ratio (NLR) and Glasgow Prognostic Score (GPS), which were measured within two weeks before operation and at the first visit after leaving the hospital.
Results
The overall survival rates were significantly worse in the high preoperative NLR/preoperative GPS/postoperative NLR group. A multivariate analysis indicated that only preoperative GPS, postoperative NLR, and the number of lymph node metastases were independent prognostic factors for a poor survival.
Conclusions
The postoperative NLR is an independent prognostic factor in patients with CRC who underwent potentially curative surgery.
