Prognostic value of neutrophil-to-lymphocyte ratio in urothelial carcinoma of the upper urinary tract and bladder: a systematic review and meta-analysis.

ABSTRACT: The neutrophil-to-lymphocyte ratio (NLR) is an inflammation marker that has prognostic value for various tumors, but its prognostic value in urothelial carcinoma (UC) remains controversial. This meta-analysis investigated the prognostic value of NLR in UC. A systematic search was performed on PubMed, ISI Web of Science, and Embase for studies focusing on the association between NLR and clinical features or prognosis of UC and published until November 2016. Prognostic outcomes and clinical features were collected and analyzed. A total of 11,538 patients from 32 studies were included in the meta-analysis. Increased pretreatment NLR predicted poor overall survival (hazard ratio [HR] = 1.72, 95% confidence interval [CI] = 1.45-2.05), progression free survival (HR = 1.68, 95% CI = 1.44-1.96), and cancer specific survival (HR = 1.64, 95% CI = 1.39-1.93) in all the patients. The increased pretreatment NLR was correlated with increased lymphovascular invasion (HR = 1.29, 95% CI = 1.17-1.43), high tumor T stage (HR = 1.25, 95% CI = 1.12-1.39), and tumor grade (HR = 1.07, 95% CI = 1.01-1.14) but not with lymph node involvement, carcinoma in situ, multifocality, or positive margin. Our meta-analysis indicated that NLR could predict the prognosis for UC and was associated with UC progression in terms of lymphovascular invasion, tumor T stage, and tumor grade.

Project description:Previously, the preoperative neutrophil-to-lymphocyte ratio (NLR) has been demonstrated to be a beneficial prognostic marker in patients with upper tract urothelial carcinoma (UTUC). However, to the best of our knowledge, the postoperative NLR has rarely been investigated. Therefore, the present study evaluated the prognostic significance of postoperative NLR in patients with UTUC. Data of patients with UTUC who underwent surgical treatment at Kurume University hospital (Kurume, Japan) between 2004 and 2015 were retrospectively reviewed. Clinicopathological characteristics were analyzed, including pre- and postoperative NLRs. Overall survival (OS) and cancer-specific survival (CSS) rates were estimated using the Kaplan-Meier method and compared with a log-rank test. Multivariate proportional Cox regression models were applied for both endpoints to identify the independent prognostic significance of NLR. The median age of the 134 enrolled patients was 70 years. The postoperative NLR was elevated in 35 patients (26.1%). A high postoperative NLR of ≥2.5 was significantly associated with a high postoperative C-reactive protein level of ≥0.3 mg/dl, an advanced pathological T stage and positive lymphovascular invasion in surgical specimens (P<0.001, P=0.019 and P=0.024, respectively). The 5-year OS rates in patients with high and low postoperative NLR were 33.7 and 70.2%, respectively (P<0.001), and the 5-year CSS rates in patients with a high and low postoperative NLR were 33.7 and 80.7%, respectively (P<0.001). Multivariate analysis revealed that a high postoperative NLR was an independent prognostic marker for OS (hazard ratio, 4.66; 95% confidence interval, 2.11-10.00; P<0.001) and CSS (hazard ratio, 10.90; 95% confidence interval, 4.32-28.40; P<0.001), and the preoperative NLR was not identified as a prognostic marker. In conclusion, a high postoperative NLR is associated with a poor prognosis in patients with UTUC. Therefore, postoperative NLR may be a potential prognostic marker in patients with UTUC undergoing nephroureterectomy.
