Obturator nerve entrapment is a rare complication after pelvic surgery and is caused by a direct intraoperative injury or secondary to compression by a postoperative collection. We have presented the case of a 65-year-old man who had complained of right-sided medial groin pain 4 weeks after robot-assisted laparoscopic prostatectomy with bilateral pelvic lymphadenectomy. Pelvic magnetic resonance imaging showed bilateral lymphoceles with right-sided compression of the obturator nerve causing diffuse muscle edema in its innervation region.

Circulating tumor DNA (ctDNA) has the potential to cost-efficiently accelerate precision medicine trials to improve clinical efficacy and diminish costs and toxicity. However, comprehensive ctDNA profiling in metastatic prostate cancer to date has been limited.

Between March 2014 and April 2017, we recruited patients with mCRPC ( = 168) prior to ARSi in a cohort study encompassing 10 European centers. Blood samples were collected for comprehensive profiling of CellSearch-enriched circulating tumor cells (CTC) and circulating tumor DNA (ctDNA).

Objective: To investigate the prognostic value of circulating tumor cell (CTC) enumeration and dynamics, in the context of second-line endocrine therapies (ie, abiraterone acetate or enzalutamide), irrespective of prior systemic therapies.
Design, Settings, And Participants: In a prospective, multicentre study blood samples for CTC enumeration were collected from patients with mCRPC at baseline (n = 174).
