Background: The role of Neutrophil to Lymphocyte Ratio (NLR) and Platelet to Lymphocyte Ratio (PLR) in prognostication of MIBC is not clearly understood. There is growing evidence that, as markers of inflammation, they may have prognostic utility in MIBC at radical cystectomy (RC). Methods: We performed a retrospective analysis of MIBC patients who underwent RC at the Cleveland Clinic from 2/2015 to 1/2018. 84 patients were identified who were either diagnosed with TaN0M0 treated with Neoadjuvant Chemotherapy (NAC) or T1-T4N0M0 disease treated with or without NAC. For NAC, 27 patients received gemcitabine and cisplatin, 2 patients received gemcitabine and carboplatin, 4 patients received unknown regimen, and 3 patients received MVAC. Of the patients, there were 1 with Ta, 34 with T1, 44 with T2, 1 with T3 and 4 with T4 disease. Complete Blood Count with Differential closest to or on the day of resection was used. NLR and PLR were calculated by dividing Absolute Neutrophil Count and Platelet Count by the Absolute Lymphocyte Count, respectively. PLR and NLR were dichotomized at the median. Outcomes were analyzed via Kruskal-Wallis test. Results: Median follow up of patients was 28.8 months. Median NLR and PLR were 15.7 and 263, respectively. Mean NLR and PLR were 18.9 and 310, respectively. NLR and PLR did not correlate with overall survival, recurrence free survival, T or N stage post resection, or pathological response. Females were found to have a higher NLR than males. Conclusions: Contrary to previous reports, our study did not find any prognostic value of NLR and PLR in MIBC patients at RC. Further evaluation of PLR and NLR in MIBC and correlation with molecular features may help understand its potential prognostic role in patients undergoing surgical resection.
