Background: Further biomarkers are warranted to improve prognostic stratification of penile squamous cell carcinoma (PSCC) patients undergoing inguinal lymph node dissection (ILND)., Objective: To assess the prognostic value of pretreatment neutrophil-to-lymphocyte ratio (NLR) in PSCC patients undergoing ILND and to investigate its role in predicting pathologic node-positive (pN+) disease., Design, Setting, and Participants: In total, 84 consecutive patients undergoing ILND for PSCC at our institution between 1994 and 2014 were identified. Sixty-eight patients with a complete blood count and differential prior to surgery were included. Median follow-up was 35.5 mo., Outcomes Measurements and Statistical Analysis: Cut-off point analysis of NLR was performed using the Contal and O'Quigley method. Estimates of overall survival (OS), cancer-specific survival, and recurrence-free survival stratified by NLR were provided by the Kaplan-Meier method. Cox regression models were performed to determine predictors of survival and recurrence. Logistic regression models were used to identify factors associated with pathologic node-positivity., Results and Limitations: The cut-off point value was determined to be 3. Median OS was significantly shorter for patients with NLR ≥3 than those with NLR <3 (30 vs 158 mo, p<0.001). NLR ≥3 was an independent predictor of worse OS (hazard ratio=2.48; 95% confidence interval [CI]: 1.02-6.06, p=0.046). On univariable analysis, NLR ≥3 was associated with an increased risk of pN+ disease (odds ratio [OR]=3.75; 95% CI: 1.30-10.81, p=0.014). However, on multivariable analysis adjusted for primary tumor grade, lymphovascular invasion, clinical N stage, and neoadjuvant treatment receipt, the association between NLR and pN+ disease was no longer significant (OR=3.66; 95% CI: 0.82-16.42, p=0.091). The retrospective design and limited size of the study are acknowledged limitations., Conclusions: Pretreatment NLR is an independent predictor of OS in PSCC patients undergoing ILND and highlights the association between systemic inflammation and survival. Our data suggests that a simple biomarker of inflammation can serve as a prognosticator in PSCC., Patient Summary: Penile cancer is a rare malignancy in North America and Europe. Therefore, there is a lack of prognostic parameters to help predict oncologic and survival outcomes. In this report, patients with an elevated neutrophil-to-lymphocyte ratio had an increased risk of mortality., (Copyright © 2018 European Association of Urology. Published by Elsevier B.V.

Background: The efficacy of neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (BCa) was established primarily with methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC), with complete response rates (pT0) as high as 38%. However, because of the comparable efficacy with better tolerability of gemcitabine and cisplatin (GC) in patients with metastatic disease, GC has become the most commonly used regimen in the neoadjuvant setting., Objective: We aimed to assess real-world pathologic response rates to NAC with different regimens in a large, multicenter cohort., Design, Setting, and Participants: Data were collected retrospectively at 19 centers on patients with clinical cT2-4aN0M0 urothelial carcinoma of the bladder who received at least three cycles of NAC, followed by radical cystectomy (RC), between 2000 and 2013., Intervention: NAC and RC., Outcome Measurements and Statistical Analysis: The primary outcome was pathologic stage at cystectomy. Univariable and multivariable analyses were used to determine factors predictive of pT0N0 and ≤pT1N0 stages., Results and Limitations: Data were collected on 935 patients who met inclusion criteria. GC was used in the majority of the patients (n=602; 64.4%), followed by MVAC (n=183; 19.6%) and other regimens (n=144; 15.4%). The rates of pT0N0 and ≤pT1N0 pathologic response were 22.7% and 40.8%, respectively. The rate of pT0N0 disease for patients receiving GC was 23.9%, compared with 24.5% for MVAC (p=0.2). There was no difference between MVAC and GC in pT0N0 on multivariable analysis (odds ratio: 0.89 [95% confidence interval, 0.61-1.34]; p=0.6)., Conclusions: Response rates to NAC were lower than those reported in prospective randomized trials, and we did not discern a difference between MVAC and GC. Without any evidence from randomized prospective trials, the best NAC regimen for invasive BCa remains to be determined., Patient Summary: There was no apparent difference in the response rates to the two most common presurgical chemotherapy regimens for patients with bladder cancer., (Copyright © 2014 European Association of Urology.
