Objective
To investigate the clinical value of preoperative De Ritis ratio (aspartate aminotransferase/alanine aminotransferase) (DRR) in patients with transitional cell bladder cancer (TCBC) at initial diagnosis. The secondary objective was to investigate the status of systemic inflammatory parameters, such as neutrophil‐lymphocyte ratio (NLR), lymphocyte‐monocyte ratio (LMR), platelet‐lymphocyte ratio (PLR) and platelet‐monocyte ratio (PMR).
Materials and Methods
The records of patients with primary TCBC who underwent transurethral resection were retrospectively evaluated. The relationship of DRR and systemic inflammatory parameters with clinicopathological findings, recurrence and progression status was evaluated separately.
Results
There was no significant difference in the DRR according to the clinicopathological findings, recurrence and progression. Significant differences were found between the NLR and the patient groups for tumour diameter, tumour stage, tumour grade and progression. In univariate analysis, the LMR was found to be associated with progression, and also the PLR and LMR were found to be associated with recurrence. Decrease in LMR and increase in LMR score demonstrated by multiple analysis was shown as independent predictors of progression and recurrence development.
Conclusions
This paper shows a positive correlation between poor prognosis in TCBC and the systemic inflammatory markers, namely NLR, LMR, PLR and PMR, but not DRR.
Bladder cancer is the most common malignancy of the urinary tract. Radical cystectomy with pelvic lymph node dissection and a urinary diversion (UD) is the gold standard treatment of non-metastatic muscle-invasive bladder cancer (MIBC). Although ileal conduit is the standard and most commonly performed type of UD, more number of centers have recently started to perform orthotopic ileal neobladder (OIN). A novel OIN has been described in 2005 as the so-called "Leuven N-pouch", which combines the features of the commonly used Hautmann and Studer neobladders. Herein, we report our first experience with a case of Leuven N-pouch in our department, which was performed for a male patient with MIBC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
