Introduction: Salvage lymph node dissection (sLND) is a treatment option for prostate cancer (PCa) patients with nodal recurrence after radical therapy to delay tumour progression and hormonal treatment. We evaluated the outcomes in terms of biochemical recurrence (BCR), clinical regression, and cancer specific survival (CSS) in a large, multicentric series of patients treated with sLND for nodal recurrence of PCa. Methods: We retrospectively reviewed the records of 106 consecutive patients with BCR of PCa after radical treatment who underwent sLND between 2007 and 2013 at three tertiary centres. BCR was defined as prostate-specific antigen (PSA) >0.2 ng/mL. Clinical recurrence (CR) was defined as a positive imaging study or biopsy for metastasis after sLND. Kaplan–Meier curves calculated BCR-free survival (BFS), CR-free survival (CRS), and CSS. Cox regression analyses were performed to identify predictors of CR. Results: Median number of nodes removed at sLND was 21.7, with a median of three positive nodes. Immediate biochemical response after surgery was achieved in 50.9% of patients. At a median follow-up of 22.5 months, biochemical failure and CR were experienced by 67.9% and 40.5% of patients, respectively. At 2 years, BFS, CRS, and CSS were 25%, 52%, and 92%, respectively. Castrate-resistant prostate cancer (CRPC) status, PSA level at sLND, and presence of biochemical failure after sLND were significantly associated with CR after surgery. Conclusions: sLND represents a valid treatment option for selected patients with nodal recurrences, achieving a CR-free status in more than half of patients at 2 years. Patients with CRPC status or high PSA values might not be the best candidates for a sLND.

AbstractBackgroundA recent meta‐analysis (Human Reproduction Update 23, 2017 and 265) reported positive sperm retrieval rates (SRR) in 50% of patients with Klinefelter syndrome (KS) undergoing testicular sperm extraction (TESE). However, these results do not reflect the rates of SR that we observe in clinical practice. We assessed the rate and potential predictors of SR in Klinefelter patients in the real‐life setting.Materials and MethodsWe reviewed clinical data of 103 KS men who underwent TESE between 08/2008 and 03/2019 at five tertiary referral Andrology centers. Patients underwent testis ultrasound, hormonal evaluation, and genetic testing. All patients were azoospermic based on the 2010 WHO reference criteria. Conventional TESE (cTESE) or microsurgical TESE (mTESE) was performed based on the surgeon's preference. We used descriptive statistics and logistic regression models to describe the whole cohort.ResultsMedian (IQR) patient's age was 32 (24‐37) years. Baseline serum FSH and total testosterone levels were 29.5 (19.9‐40.9) mUI/mL and 3.8 (2.5‐11.0) ng/mL, respectively. Conventional TESE and mTESE were performed in 38 (36.5%) and 65 (63.5%) men, respectively. The sperm retrieval rate was 21.4% (22/103 men). Fifteen patients used spermatozoa for ICSI and five ended in live birth children. Patients with positive SR were similar to those with a negative TESE in terms of clinical, hormonal, and procedural parameters (all P > .05). Logistic regression analyses confirmed the lack of association between clinical, hormonal, and procedural parameters with SR outcome.DiscussionGiven the conflicting results in the literature regarding SRR in KS, patients should be carefully counseled regarding TESE outcomes based on data from published literature and local results.ConclusionsIn the real‐life setting, we observed a lower SRR (21.4%) than that reported in meta‐analyses in our cohort of KS patients. No associations between clinical, hormonal, and procedural variables with TESE success were found.
