dc.description  AN ELEVATED NEUTROPHIL/LYMPHOCYTE RATIO IS ASSOCIATED WITH POOR PROGNOSIS IN STAGE II RESECTED COLON CANCER Background: The neutrophil/lymphocyte ratio is an effective marker of inflammation and can have prognostic value in surgical patients. Aim: To evaluate the effect of an increased neutrophil/lymphocyte ratio (NLR) on perioperative complications and overall and disease-free survival in patients undergoing elective resection for stage II colon cancer. Material and methods: Data was obtained from clinical charts, preoperative blood results and hospital records of all patients undergoing an elective curative resection for colon cancer, between 2000 and 2007. Preoperative NLR was calculated.  Follow-up was obtained from a prospectively maintained colorectal cancer database, clinical records and questionnaires.  Uni and multivariable analysis were performed to identify associations, and survival analysis was performed using Kaplan-Meier curves. Results: One hundred twenty two patients with a mean age of 69 years (52% males), were evaluated. Median follow-up was 73 months, and overall survival for 1 and 5 years was 95% and 68%, respectively. On a multivariable analysis after adjusting for age, sex, tumor depth invasion, use of adjuvant therapies and American Society of Anesthesiology preoperative risk score, an NLR > 5 was associated with an increased perioperative complication rate (odds ratio: 3.06, p= 0.033).  Kaplan-Meier survival analysis showed a worse overall and disease-free survival for patients with NLR greater than five. Conclusions:  A preoperative NLR of five or more is associated with greater perioperative morbidity and worse oncological outcomes in patients undergoing resection for elective stage II colon cancer. es-ES
