Mid-term oncologic outcomes of radical prostatectomy in lymph node metastatic prostate cancer patients.

OBJECTIVES: Lymph node invasion (LNI) has been reported in 10-15% of pelvic lymph node dissection during radical prostatectomy (RP). The objective of this study was to describe the mid-term oncological outcomes in prostate cancer (PCa) patients with metastatic lymph node. METHODS: We conducted a retrospective study at two French referral centers including consecutive cN0 PCa patients who underwent RP and extended pelvic lymph node dissection and had lymph node metastases on final pathological analysis (pN1) between January 2000 and May 2020. Follow-up was per institution, which generally included a PSA level measurement every 3 to 12 months for 5 years and annually thereafter. RESULTS: A total of 123 patients were included: two (1.6%) low-risk, 64 (52%) intermediate-risk and 57 (46.4%) high-risk PCa according to the D'Amico risk classification. The median number of nodes removed and metastatic nodes per patient was 15 (IQR 11-22) and 1 (IQR 1-2), respectively. Adverse pathological features, i.e., ≥pT3a stage, ISUP grade ≥3, and positive surgical margins were reported in 113 (91.9%), 103 (83.7%), and 73 (59%) of cases, respectively. Postoperative treatment was administered in 104 patients, including radiotherapy alone (n=6), androgen deprivation therapy alone (n=27) or combination with androgen deprivation therapy and radiotherapy (n=71). The mean follow-up was 42.7 months. The estimated 3-year biochemical-free survival, clinical recurrence-free survival, and cancer-specific survival was 66% and 85% and 98.8%, respectively. In Cox regression analysis, the number of metastatic nodes was associated with clinical recurrence (P=0.04) and a persistently elevated PSA with biochemical recurrence (P<0.001). CONCLUSION: The management of lymph node metastatic PCa patients is challenging. Risk stratification of node-positive patients, based on postoperative PSA levels and pathologic features being identified, should help physicians determine which patient would best benefit from multimodal treatment.

TORSAFUF - Surgical exploration for torsion of spermatic cord suspicion and risk factors for unnecessary surgery: Results of a French nationwide retrospective study on 2940 patients.

BACKGROUNDS: Spermatic cord torsion is a frequent urological emergency that mostly concerns teenagers and young adults. This study aimed to determine the clinical and surgical characteristics of young adults who had scrotal exploration for suspected spermatic cord torsion and to identify clinical risk factors associated with needless scrotal exploration. METHODS: We retrospectively collected national data from patients aged 12years and older who underwent a surgical exploration for suspicion of torsion of the spermatic cord between 2005 and 2019 in 17 hospitals. We analyzed demographics, surgical and postoperative characteristics in our population. We compared the cohort according to the intraoperative diagnosis of torsion or not. RESULTS: In total, 2940 had surgical exploration: 1802 (61.3%) patients had torsion of the spermatic cord and 1138 (38.7%) had another diagnosis. In multivariate analysis, age (OR: 1.04; 95% CI: 1.01-1.06; P=0.005), medical history of cryptorchism (OR: 4.14; 95% CI: 1.05-16.31; P=0.042) and VAS pain score (OR: 0.91; 95% CI: 0.83-0.98; P=0.018) were risk factors significantly associated with unnecessary surgical exploration. The rate of complications in the 90days after surgery was 11% in the "torsion" group, and 9.7% in the "non-torsion" group (P=0.28). CONCLUSION: Scrotal exploration without intraoperative diagnosis of torsion was performed in 40% of our cohort. VAS pain score and cryptorchism history can help for the diagnosis but scrotal exploration remains the way to diagnose spermatic cord torsion and should be performed on the slightest suspicion, even after 24hours of symptoms, as the chances for testicular salvage remains around 50%.
