“…Bladder cancer is one of the most prevalent cancers in the urinary tract and the seventh most common tumor in the male population worldwide, while it drops to the 11th if both genders are considered [ 1 , 2 ]. Approximately 75% of patients with bladder cancer present with disease confined to the mucosa or submucosa, which is referred to as non-muscle-invasive bladder cancer (NMIBC) and this proportion is even higher in younger patients (< 40 years) [ 3 ].…”

Purpose To evaluate the prognostic value of the aspartate transaminase/alanine transaminase (AST/ALT) ratio in primary non-muscle-invasive bladder cancer (NMIBC) using propensity score matching (PSM) analysis. Methods We retrospectively collected the clinical and pathological data from 314 patients with primary NMIBC who underwent transurethral resection of bladder tumor. The full cohorts were divided into a low AST/ALT ratio group and a high AST/ALT ratio group according to the optimal cut-off value which was obtained based on the analysis of the receiver operating characteristic curve for the 3-year recurrence-free survival (RFS). After 1:1 PSM, the correlation between preoperative AST/ALT ratio and survival prognosis was evaluated by Kaplan–Meier analysis with log-rank tests. The independent prognostic factors for RFS and progression-free survival (PFS) were also analyzed. Results The optimum cutoff value of the preoperative AST/ALT ratio was 1.40. Before PSM, a high AST/ALT ratio was correlated with the larger proportion of age > 60 years (P = 0.007) and the worse pathological T stage (P < 0.001). After PSM, patients with a high AST/ALT ratio had poorer RFS and PFS than patients with a low AST/ALT ratio (all P < 0.001). In addition, multivariate Cox regression analysis indicated that preoperative AST/ALT ratio was considered as an independent prognostic factor of RFS (HR 2.865; 95%CI 1.873–4.381; P < 0.001) and PFS (HR 4.771; 95%CI 2.607–8.734; P < 0.001) in patients with primary NMIBC. Conclusions The high AST/ALT ratio group tended to have poorer RFS and PFS than the low AST/ALT ratio group. Our results also indicated that the elevated preoperative AST/ALT ratio could be seen as a useful prognostic biomarker for predicting early disease recurrence and progression in patients with primary NMIBC.
