ABSTRACT
Radical pelvic surgery is a surgical method mainly used to treat tumors in the pelvic cavity, and erectile dysfunction (ED) is a common sexual dysfunction after surgery. The incidence of ED after radical pelvic surgery is not uniformly understood due to differences in surgical approaches and methods of investigation. The main causes of postoperative ED include intraoperative neurovascular injury, psychosomatic factors and preoperative patient characteristics, with intraoperative injury to the neurovascular bundle being the most common. Studies have shown that the occurrence of postoperative ED can be prevented by active intervention, but still lack of effective treatment measures. This article reviews and summarizes the clinical epidemiological features and research progress in recent years on ED after radical pelvic surgery, and discusses specific measures for the prevention and treatment of postoperative ED.
ABSTRACT
The traditional androgen deprivation therapy has been challenged since the appearance of castration resistant prostate cancer (CRPC). More and more researches are focusing on searching the proper molecular target to inhibit the progression of tumors. Ubiquitin specific protease 7(USP7), as an important deubiquitinating enzyme, regulates the half-life or subcellular localization of key proteins via posttranslational modification. It has been reported recently that prostate cancer cells are suppressed by USP7 inhibitors, but the complicated mechanisms remain to clarify. In this paper, we review the mechanism of USP7 in prostate cancer, suggesting the potential value of USP7 inhibitors in the treatment of CRPC.
