ABSTRACT
Purpose@#To investigate the correlation between preoperative De Ritis ratio (aspartate transaminase [AST]/alanine transaminase [ALT]) and postoperative clinical outcome in patients with upper urinary tract carcinoma (UTUC) who underwent radical nephroureterectomy (RNU) and adjuvant chemotherapy (ACH). @*Materials and Methods@#We respectively analyzed the clinical and pathological data of 102 patients who underwent RNU and ACH for UTUC. Patients were divided into 2 groups, according to the optimal value of AST/ALT ratio. The effect of the AST/ALT ratio was analyzed by the Kaplan-Meier method and Cox regression hazard models for patients’ cancer-specific survival (CSS) and overall survival (OS). @*Results@#Mean survival time was 50.5±41.2 months. Mean age was 61.4±9.7years. Forty-one of the patients (46.5%) were in the high AST/ALT group. According to receiver operating characteristic analysis, the optimal AST/ALT ratio was 1.2. In Kaplan-Meier analyses, the high AST/ALT group showed worse outcomes in OS (p=0.007) and CSS (p=0.011). Using Cox regression models of clinical and pathological parameters to predict OS, high AST/ALT ratio (hazard ratio [HR], 5.428; 95% confidence interval [CI]; 1.803–16.334; p=0.002), pathological T3 (pT3) or higher (HR, 1.464; 95% CI; 1.156-1.857; p=0.002), and to predict CSS, high AST/ALT ratio (HR, 4.417; 95% CI; 1.545–12.632; p=0.005), and pT3 or higher (HR, 1.475; 95% CI; 1.172–1.904; p=0.002) were determined as independent prognostic factors. @*Conclusions@#Pretreatment AST/ALT ratio is a significant independent predictor of CSS and OS in advanced UTUC patients receiving systemic ACH after RNU.
