We examined the expression of ETS- 1 using immunohistochemical staining of paraffin-embedded prostate carcinoma tissue obtained by needle biopsy from 69 mostly advanced PCa patients. ETS-1 expression was compared with the clinicopathological characteristics of the 69 patients, including 25 who underwent ADT as a primary treatment. As a result, PCa patients with higher expression of ETS-1 were significantly more likely to be of high stage and high Gleason score （P〈O.05）. There was no significant association between ETS-1 expression and the initial prostate-specific antigen （PSA） level. In the 25 patients treated by ADT, the staining score for ETS-1 was significantly associated with rapid development of castration-resistant disease within 24 months （P〈O.05）, whereas the Gleason score and PSA level were not. In conclusion, increased ETS-1 expression was associated with a higher stage, higher Gleason score and shorter time to castration-resistant progression. These data suggest that immunostaining for ETS-1 could be a molecular marker for predicting a poor clinical outcome for PCa patients, oarticularlv those with hi^h-risk disease.展开更多

Methods: We enrolled 376 patients, who an-swered a self-administered questionnaire on CAM use, psychological health locus of control (HLC), and general-health-related quality of life (GHQL). Detailed information regarding CAM use according to the transtheoretical model, and the time at initiation and abandonment of CAM use were assessed. Medical information was also extracted from patient charts. Results: 45.7% of patients belonged to the “precontem-plation” stage, 29.8% to the “contemplation” stage, 1.9% to the “preparation” stage, 14.4% to the “action” stage, and 8.2% to the “relapse” stage. Although patient age and educational status had a significant impact on stage of CAM use, HLC and GHQL were not associated with them. The time-course of prevalence of CAM use during follow-up was divided into three phases: “initial,” “rapid-increase,” and “main-tenance”. Conclusions: Among patients under-going radical prostatectomy, non-users can be classified into several behavioral stages, while users do not use CAM constantly during fol-low-up.展开更多

Here, we present our initial experiences using NerbridgeTM, a novel conduit for peripheral nerve regeneration, rather than utilizing sural nerve grafting, in robot-assisted laparoscopic radical prostatectomy to overcome autograft problems such as prolongation of operation time and postoperative abnormal sensation. This novel artificial conduit interposition can be technically feasible when combined with robotic surgery, and prospective randomized controlled trials with high patients-numbers and long follow-up periods are warranted.展开更多
