OBJECTIVES: To evaluate the association of neuthophyl/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) with BCG intravesical responses in patients with initial diagnosis of non/muscle invasive bladder tumor high-risk (NMIBC).
MATERIAL AND METHODS: Retrospective multicenter study on patients with initial diagnosis of high-grade NMIBC treated with BCG between January 2016 and December 2017. Initially a total of 74 patients were collected. Those patients with mixt pathology, cis, chronic corticoid usage and lost to follow-up, were excluded. Induction BCG (x6) and BCG maintenance schedules were administered (x9) over 1 year. Demographic variables (sex, age, BMI) and blood variables (NLR, PLR) before BCG instillation were collected. Response to treatment was defined as absence of recurrence and/ or progression. A statistical analysis with T-student, Chi square, ANOVA and ROC curves was performed.
RESULTS: Final study cohort included a total of 50 patients. 10 females and 40 males. Median age was 70 year old. All patients had pure urothelial carcinoma, 12 with pTa and 38 with pT1. Median follow-up was 24 months. A total of 28% had a recurrence. No correlation between NLR or PLR and BCG response was observed (p=0.738; p= 0.768). Neither a cut off was established through ROC curves. At multivariate analysis, there was no significative relationship between recurrence and the clinical and blood samples analyzed (sec, age, BMI, NLR, PLR)CONCLUSION: No correlation between NLR and PLR has been reported with BCG response on high-grade NMIBC.
