Association between early change in neutrophil‐to‐lymphocyte ratio after radical cystectomy and treatment outcomes

Objectives To evaluate the associations of peri‐operative neutrophil‐to‐lymphocyte ratio (NLR) and change in NLR with survival after radical cystectomy. Patients and Methods We retrospectively reviewed a multicentre cohort of patients with bladder cancer who underwent radical cystectomy between 2010...

Description
Summary:Objectives To evaluate the associations of peri‐operative neutrophil‐to‐lymphocyte ratio (NLR) and change in NLR with survival after radical cystectomy. Patients and Methods We retrospectively reviewed a multicentre cohort of patients with bladder cancer who underwent radical cystectomy between 2010 and 2020. Preoperative NLR, postoperative NLR, delta‐NLR (postoperative minus preoperative NLR) and NLR change (postoperative divided by preoperative NLR) were calculated. Patients were stratified based on elevation of preoperative and/ or postoperative NLR above the median values. Multivariable Cox regression models were used to evaluate the associations of peri‐operative NLR and NLR change with survival. Results The study cohort included 346 patients with a median age of 69 years. The median (interquartile range) preoperative NLR, postoperative NLR, delta‐NLR and NLR change were 2.55 (1.83, 3.90), 3.33 (2.21, 5.20), 0.43 (−0.50, 2.08) and 1.2 (0.82, 1.96), respectively. Both preoperative and postoperative NLR were elevated in 110 patients (32%), 126 patients (36%) had an elevated preoperative or postoperative NLR, and 110 patients (32%) did not have an elevated NLR. On multivariable analysis, increased preoperative and postoperative NLR were significantly associated with decreased survival. While delta‐NLR and NLR change were not associated with outcome, patients with elevations in both preoperative and postoperative NLR had the worst overall (hazard ratio [HR] 2.97, 95% confidence interval [CI] 1.78, 4.95; P
