The androgen receptor splice variant-7 (AR-V7) has been implicated in the development of castration-resistant prostate cancer (CRPC) and resistance to abiraterone and enzalutamide. ⋯ In this study we found that levels of the protein AR-V7 were higher in patients with advanced prostate cancer. A higher level of AR-V7 identifies a group of patients who respond less well to certain prostate cancer treatments and live for a shorter period of time.

We evaluated the accuracy of 68Ga-prostate-specific membrane antigen-HBED-CC (68Ga-PSMA) positron emission tomography/computed tomography (PET/CT) for nodal staging prior to lymph node dissection (LND) in patients with prostate cancer (PCa). Thirty-four patients with histologically proven PCa underwent 68Ga-PSMA-HBED-CC PET/CT prior to radical prostatectomy with primary LND (pLND; n=20) and PET/CT prior to secondary LND (sLND; n=14). Accuracy of PET and CT were analysed separately for staging of the following 71 lymph node (LN) regions: pelvic left (n=30), pelvic right (n=31), presacral (n=3), and para-aortic (n=7). ⋯ PET was more accurate for nodal staging compared with CT both at pLND (88% vs 75%) and sLND (77% vs 65%). Overall, 68Ga-PSMA PET/CT provides accurate nodal staging prior to pLND and sLND for PCa. PATIENT 68Ga-PSMA positron emission tomography/computed tomography is accurate in detecting tumour spread to lymph nodes before patients undergo surgery for prostate cancer.

Radical cystectomy (RC) is associated with frequent morbidity and prolonged length of stay (LOS) irrespective of surgical approach. Increasing evidence from colorectal surgery indicates that minimally invasive surgery and enhanced recovery programmes (ERPs) can reduce surgical morbidity and LOS. ERPs are now recognised as an important component of surgical management for RC. However, there is comparatively little evidence for ERPs after robot-assisted radical cystectomy (RARC). Due to the multimodal nature of ERPs, they are not easily validated through randomised controlled trials. ⋯ There is currently a lack of high-level evidence exploring the benefits of enhanced recovery programmes (ERPs) in patients undergoing robot-assisted radical cystectomy (RARC). We reported a consensus view on a standardised ERP specific to patients undergoing RARC. It was formulated by experts from high-volume RARC hospitals in Europe, combining current evidence for ERPs with experts' knowledge of perioperative care for robotic surgery.
