RESUMEN
INTRODUCTION: Abiraterone acetate + prednisone (AAP) and docetaxel have proven their efficacy in the treatment of patients with newly diagnosed metastatic hormone-sensitive prostate cancer (mHSPC) in clinical trials. However, real-world data are scarce. The goal of this study is to evaluate real-world data on the efficacy and safety of these therapies in mHSPC patients. PATIENTS AND METHODS: Records of 93 patients from 21 different centres were retrospectively reviewed. Primary and secondary endpoints were radiographic and PSA progression-free survival (RPFS - PSA-PFS) and cancer specific and overall survival (CSS - OS), respectively. Adverse events (AEs) were evaluated according to the Common Terminology Criteria for Adverse Events version 5.0. Differences in oncological outcome and AEs were evaluated between three treatment groups: ADT only (N=26) - ADT + AAP (N=48) - ADT + docetaxel (N=19). Survival analysis was performed using Kaplan-Meier statistics. RESULTS: Median RPFS was 13 months (95% confidence interval [CI]: 9-17) for ADT only, 21 months (95% CI: 19-23) for ADT + AAP and 12 months (95% CI: 11-14) for ADT + docetaxel (p = 0.004). The 1-year PSA-PFS, CSS and OS were 73.5%, 90.7% and 88.7%, respectively, with no significant differences between the three groups. Adverse events of grade 3 or higher were not observed more frequently. CONCLUSION: Retrospective real-world data show a significantly longer RPFS for mHSPC patients treated with ADT + AAP compared to ADT only or ADT + docetaxel at short-term follow-up. This can aid in counselling of mHSPC patients in daily clinical practice.

PURPOSE: After Endoscopic Enucleation of the Prostate (EEP) for benign prostatic obstruction (BPO), men remain at risk for prostate cancer (PCa). Significant PSA changes occur after enucleation, which interfere with later screening for PCa. It remains unclear which patients need further diagnostic investigations for PCa after EEP. The goal of this study was to identify an independent predictor for PCa diagnosis after Holmium Laser Enucleation of the Prostate (HoLEP) in patients whose HoLEP resection specimen did not show PCa. METHODS: Data of 773 patients who underwent HoLEP for BPO between 2010 and 2018 in a referral center were analyzed. Exclusion criteria were PCa detection in the HoLEP specimen or absence of post-operative PSA values. Patients were divided in a PCa group and Control group depending on whether or not PCa was detected during follow-up after HoLEP. The predictive value for future diagnosis of PCa of different forms of PSA-change after HoLEP was analyzed by multivariate Cox regression and ROC analysis. RESULTS: Overall, 24 (4.2%) patients developed PCa after HoLEP. At 5 year follow-up, the PCa-free survival rate was 85%. First post-operative PSA was an independent predictor of PCa diagnosis after HoLEP (HR 1.106, 95% CI 1.074-1.139, p < 0.001, ROC AUC 0.903) with an optimal cut-off value of 1.73 ng/ml (sensitivity 83.3%, specificity 82.3%). CONCLUSIONS: For patients who underwent HoLEP for BPO, post-operative PSA after HoLEP is an independent predictor for future PCa diagnosis. When PSA is > 1.73 ng/ml within the first year after HoLEP, rigorous follow-up and diagnostic investigations for PCa are indicated.

Recent reports have demonstrated that robot-assisted laparoscopic cystectomy is technically feasible. However, wide-spread acceptance of this promising technique is limited due to long operating times and lacking long-term data especially on oncological outcome. After establishing robot-assisted laparoscopic prostatectomy (n=250) we report technical and functional results of a large series of patients undergoing laparoscopic cystectomy with the da Vinci surgical system (DVSS).27 patients (24 males) underwent laparoscopic radical cystectomy with the DVSS (Intuitive Surgical) between Jan 2004 and Dec 2006. Indications for cystectomy were muscle-invasive transitional cell carcinoma (TCC) or leiomyosarcoma of the urinary bladder (n=24) and bladder shrinking following prior radiotherapy for TCC (n=3). A pelvic lymphadenectomy was routine part of the procedure. Urinary diversions were ilieal conduits (n=19) and ileal neobladders (n=8). Mean operating time was 340 minutes (range 150-450) with a mean blood loss of 301 mL (range 50-550). The mean number of lymph nodes retrieved during lymphadenectomy was 23. Surgical margins were negative except in one case. After a mean follow-up of 10.2 months, 2 perioperative (anastomotic leakage, adhesions) and 3 postoperative complications (ileus, intestinal fistula) occurred. 6/7 patients reported satisfying erectile function following nerve-sparing surgery. Day-time continence was completely restored after a mean 3.5 months in 7/8 patients.Robot-assisted laparoscopic cystectomy is a safe procedure. Satisfying functional and oncological short-term results can be achieved within acceptable operating time limits.

Surgical margins were negative except in one case. After a mean follow-up of 10.2 months, two perioperative (anastomotic leakage, adhesions) and three postoperative complications (ileus, intestinal fistula, urinary tract obstruction) occurred. Six out of seven patients reported satisfying erectile function following nerve-sparing surgery. Day-time continence was completely restored after a mean 3.5 months in seven of eight patients. Robot-assisted laparoscopic cystectomy is a safe procedure. Satisfying functional and oncological short-term results can be achieved within acceptable operating time limits.
RESUMEN
A retroperitoneal bleeding is an unusual complication of extracorporeal shockwave lithotripsy (ESWL), which can be treated in a conservative way most of the time. However, an intra-abdominal bleeding after ESWL is extremely rare, which can cause life-threatening situations and requires an immediate intervention. Probably, only patients with a certain tissue fragility or connective tissue disorder are at risk to develop such an intra-abdominal bleeding. We present a case of a serious intra-abdominal bleeding due to a rupture of the vena mesenterica superior in an Ehlers-Danlos patient, evoked by an ESWL.

In this paper, we describe a case of skeletal muscle metastasis from a conventional (clear cell) renal cell carcinoma, two years after nephrectomy. Our first clinical tentative diagnosis was soft tissue tumour, showing the mimicking capacity of renal cell carcinoma. A review of literature shows that skeletal muscle metastases from renal cell carcinoma are extremely rare: only 16 cases have been described. In 5/16, the muscle mass was the initial manifestation of the renal tumour. In the other 11/16, the muscle masses were metachronous (10 months-16 years). We conclude that, when confronted with a patient with a muscle mass and a history of renal cell carcinoma, one should always keep in mind the possibility of a (late) renal cell carcinoma metastasis.

OBJECTIVE: Inflammation is a frequent histological finding in prostate biopsies, performed on men without prostatic malignancy or clinical prostatitis. We investigated the relationship between morphological parameters of inflammation in prostatic tissue and total serum prostate-specific antigen (PSA) and prostate-specific antigen density (PSAD) levels to determine if subclinical inflammation can cause elevation of PSA and PSAD. METHODS: We reviewed 268 prostate biopsies, performed on 238 men with elevated PSA and/or abnormal digital rectal examination of the prostate. All premalignant and malignant biopsies and cases of clinical prostatitis were excluded. The inflammation in the remaining 145 prostate biopsies was scored for extent of inflammation and aggressiveness of inflammation, using the four-point scale designed by Irani and co-workers. In this prostatic inflammation scoring system, extent of inflammation is graded from 0 up to 3 according to the degree of invasion of inflammatory cells in prostatic tissue. Aggressiveness of inflammation is graded from 0 up to 3 according to the degree of contact or disruption of prostatic glandular epithelium by inflammatory cells. RESULTS: Each of the studied biopsies showed inflammatory cells. Median PSA levels in grades 1, 2 and 3 of extent of inflammation were, respectively, 5.7, 6.8 and 13. 0. Median PSAD levels in these groups were 0.13, 0.16 and 0.33. There was no significant difference between these grades for PSA nor for PSAD. Median PSA levels in grades 0, 1 and 2 of aggressiveness of inflammation were, respectively, 3.9, 5.9 and 8.9. Median PSAD levels in these groups were 0.12, 0.18 and 0.17. For both parameters, there was a significant difference between grades (respectively, p = 0.0028 and p = 0.0330). CONCLUSION: Inflammation of the prostate is a histological finding in almost every set of prostate biopsies, even when there are no signs of clinical prostatitis. This subclinical inflammation can cause PSA elevation. Not the extent of inflammation is of importance, but the disruption of epithelial integrity caused by the inflammatory infiltrate. When confronted with a patient with an elevated PSA level whose prostate biopsies reveal no malignancy but only inflammation, this concept can help in determining the need for quick repeat biopsies.
