چکیده انگلیسی

BackgroundPretreatment neutrophil-to-lymphocyte ratio (NLR) is a marker of systemic inflammation that has been associated with adverse survival in a variety of malignancies. However, the relationship between NLR and oncologic outcomes following radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB) has not been well studied.ObjectiveTo evaluate the association of preoperative NLR with clinicopathologic outcomes following RC.Design, setting, and participantsWe identified 899 patients who underwent RC without neoadjuvant therapy at our institution between 1994 and 2005 and who had a pretreatment NLR.Outcome measurements and statistical analysisPreoperative NLR (within 90 d prior to RC) was recorded. Recurrence-free, cancer-specific, and overall survival were estimated using the Kaplan-Meier method and compared using the log-rank test. Multivariate Cox proportional hazard and logistic regression models were used to analyze the association of NLR with clinicopathologic outcomes.Results and limitationsMedian postoperative follow-up was 10.9 yr (interquartile range: 8.3-13.9 yr). Higher preoperative NLR was associated with significantly increased risks of pathologic, extravesical tumor extension (odds ratio [OR]: 1.07; p = 0.03) and lymph node involvement (OR: 1.09; p = 0.02). Univariately, 10-yr cancer-specific survival was significantly worse among patients with a preoperative NLR (≥2.7 [51%] vs <2.7 [64%]; p < 0.001). Moreover, on multivariate analysis, increased preoperative NLR was independently associated with greater risks of disease recurrence (hazard ratio [HR]: 1.04; p = 0.02), death from bladder cancer (HR: 1.04; p = 0.01), and all-cause mortality (HR: 1.03; p = 0.01).ConclusionsElevated preoperative NLR among patients undergoing RC is associated with significantly increased risk for locally advanced disease as well as subsequent disease recurrence, and cancer-specific and all-cause mortality. These data suggest that serum NLR may be a useful prognostic marker for preoperative patient risk stratification, including consideration for neoadjuvant therapy and clinical trial enrollment.
