We aimed to evaluate prognostic significance of preoperatively assessed aspartate aminotransaminase (AST)/alanine aminotransferase (ALT) (De Ritis) ratio on survival in bladder cancer (BC) patients underwent radical cystectomy (RC). ⋯ Preoperative elevated De Ritis ratio could be an independent prognostic factor in BC patients underwent RC. Our results should be confirmed by large and properly designed prospective, randomized trials.

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.

Placenta specific 8 (PLAC8) plays an important role in many different cellular processes and human diseases, including multiple types of cancer. However, the functional role of PLAC8 in clear cell renal cell carcinoma (ccRCC) has never been elucidated. ⋯ Our findings suggest that PLAC8 may be a potential prognostic indicator and therapeutic target for ccRCC.

To determine the accuracy of ultrasound (US) and magnetic resonance imaging (MRI) in the diagnosis of penile fracture and preoperative mapping for modified surgical repair. ⋯ Both modalities are extremely helpful for the diagnosis of penile fracture. Considering the cost-efficiency and accessibility of ultrasonography, US is recommended as the first-line tool for both diagnosis and preoperative mapping. MRI may be used as a complementary study in the patients for whom US fails to visualize or precisely define the tunica defect.
