Recently, several studies have shown that the De Ritis ratio (aspartate transaminase/alanine transaminase) can be a useful prognostic biomarker for certain types of malignant tumors. However, the prognostic value of the De Ritis ratio in patients with upper tract urothelial carcinoma remains largely unknown. The aim of the present study was to evaluate the prognostic significance of the De Ritis ratio in patients who had undergone radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma. ⋯ The De Ritis ratio can be a significant predictor of oncological outcomes in patients with upper urinary tract urothelial carcinoma after surgery.

To illustrate whether De Ritis (aspartate transaminase-AST/alanine transaminase-ALT) ratio is useful in risk stratification of localized prostate cancer and propose an easy predictive model for biochemical recurrence-free survival (BCRFS). ⋯ Higher De Ritis ratio could be predictive for worse pathological outcomes and higher BCR in localized prostate cancer patients. A predictive model which incorporates De Ritis ratio, Gleason Score and pathological tumor stage could help risk stratification for BCRFS.
