Abstract

Background: Although the wide application of robot-assisted radical prostatectomy (RARP) in recent years, studies about long urinary continence were few. In this study, we aimed to examine the outcomes of continence rates (CRs) and determine the risk and protective factors of early and late urinary continence in patients with prostate cancer (PCa) undergoing RARP. Methods: This retrospective study included 650 patients treated with RARP who completed perioperative data and at least one year of follow-up from January 2009 to November 2017. We analyzed the preoperative, intraoperative, and postoperative parameters of the patients. Continence was defined as no pad use. CRs from one to 48 months postoperatively were examined. Logistic regression analysis was performed to evaluate the associations between the predictive factors and urinary continence in the early and late stages. Results: CRs of the patients at one, three, six, 12, 24, 36, and 48 months postoperatively were 40.62%, 60.92%, 71.38%, 78.77%, 79.96%, 79.51%, and 76.50%, respectively. There were no significant differences in CR from 12 to 48 months postoperatively (P=0.766). Logistic regression analysis proved that pelvic lymph node dissection (PLND) was a significant ri...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
