Objectives: To determine the diagnostic value of immature granulocyte (IG) count before treatment in patients with invasive bladder cancer and to compare this marker with other routine inflammation markers. Methods: In this retrospective observational study, the data of patients who underwent transurethral resection for the diagnosis of bladder cancer were analyzed. Two groups were formed as those with non-muscle invasive bladder cancer (NMIBC) and those with muscle invasive bladder cancer (MIBC). Demographic data, routine laboratory tests, neutrophil/lymphocyte ratio (NLR), red blood cell distribution width (RDW), and IG levels of the groups were recorded and compared. Results: There were 57 patients in the NMIBC group and 55 patients in the MIBC group. NLR, RDW and PLR levels were significantly higher in the MIBC group (p<0.001, each). In univariate analysis neutrophil, lymphocyte, NLR, IG, and RDW were identified as predictors for MIBC. In multivariate analysis, NLR, RDW and IG were significantly associated with the predictors of MIBC (p<0.001,each). Cut-off values were 3.06 for NLR, 11.15 for RDW, and 0.08 for IG. Conclusion: IG is an important inflammatory marker included in complete blood count parameters and may be useful in predicting muscle invasion in patients with bladder cancer.
