Abstract

 

Objective: The aim of this study is to examine the usefulness of preoperative neutrophile-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratios to predict pathological upstaging of invasive bladder cancer who underwent radical cystectomy.

 

Material and methods: A total of 126 patients who underwent radical cystectomy at our clinic between January 2006 and March 2015 were retrospectively analysed. One hundred and twelve patients with organ-confined invasive bladder tumors (T2) detected at histopathological examination of transuretral resection material were included in the study. Upstaging was seen at histopathological examination of radical cystectomy specimens of 42 patients. We compared preoperative neutrophile-to-lymphocyte ratio, platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio between upstaged and not-upstaged groups.

 

Results: There were no statistically significant correlation between age, time to radical cystectomy, gender, lymphocyte-to-monocyte ratio, platelet-to-lymphocyte ratio ratios and carcinoma in situ in upstaged and non-upstaged groups. Statistical analyses showed that preoperative neutrophile-to-lymphocyte ratio  was higher in upstaged patients (p=0.009). In multivariate analysis preoperative neutrophile-to-lymphocyte ratio and positive surgical margin were significantly higher in upstaged group.

 

Conclusion:  In organ-confined muscle invasive bladder cancer neutrophile-to-lymphocyte ratio seems to be an acceptable parameter to predict locally advanced disease.
