Impact of COVID-19 on the time to counseling and treatment of prostate cancer.

PURPOSE: This study investigates how the COVID-19 pandemic (CP) impacted the timeline between initial diagnosis (ID) of prostate carcinoma and subsequent therapy consultation (TC) or radical prostatectomy (RP) due to the implementation of a "minimal contact concept," which postponed clinical examinations until the day of admission. METHODS: We analyzed patient data from a tertiary care center from 2018 to September 2021. The focus was on comparing the time intervals from ID to TC and from ID to RP before and during the CP. RESULTS: Of 12,255 patients, 6,073 (61.6%) were treated before and 3,791 (38.4%) during the CP. The median time from ID to TC reduced from 37 days (IQR: 21 - 58d) pre-CP to 32 days (IQR: 20 - 50d) during CP (p < 0.001). Similarly, the time from ID to RP decreased from 98 days (IQR: 70 - 141d) to 75 days (IQR: 55 - 108d; p < 0.001) during the CP. There was a significant decrease in low-risk tumor cases at ID (18.9% vs. 21.4%; p = 0.003) and post-RP (4% vs. 6.7%; p < 0.001) during the CP. CONCLUSION: Our findings suggest that the COVID-19 pandemic facilitated more timely treatment of prostate cancer, suggesting potential benefits for both low-risk and aggressive tumor management through expedited clinical procedures.

Histopathological results of radical prostatectomy specimen of men younger than 50 years of age at the time of surgery: possible implications for prostate cancer screening programs?

INTRODUCTION: Prostate cancer (PCa) detection is usually achieved by PSA measurement and, if indicated, further diagnostics. The recent EAU guidelines recommend a first PSA test at the age of 50 years, if no family history of PCa or BRCA2 mutation exists. However, some men might harbor significant PCa at younger age; thus we evaluated the histopathological results of men treated with radical prostatectomy (RP) in their 40 s at our institution. MATERIALS AND METHODS: We relied on the data of all patients who underwent RP in our institution between 1992 and 2020 and were younger than 50 years at the time of surgery. The histopathological results are descriptively presented. Moreover, we tested the effect of a positive family history on the descriptive results. RESULTS: Overall, 1225 patients younger than 50 years underwent RP at our institution. Median age was 47 years. Most patients showed favorable histopathological characteristics. However, 20% of patients had extraprostatic disease (≥ pT3a), 15% had ISUP Gleason grade group ≥ 3, and 7% had positive lymph nodes (pN1). Patients with a known positive family history did not have a higher rate of adverse disease as their counterparts with a negative family history. DISCUSSION: Our data show that the majority of patients who were diagnosed with PCa at a very young age had favorable histopathological RP characteristics. However, a non-negligible proportion of patients already showed locally advanced disease and would have probably benefited from earlier PCa detection. This should be kept in mind when PCa screening recommendations are proposed.

Evaluation of Risk Factors for Adverse Functional Outcomes after Radical Prostatectomy in Patients with Previous Transurethral Surgery of the Prostate.

INTRODUCTION: A history of transurethral surgery of the prostate is generally considered as a risk factor of adverse functional outcomes after radical prostatectomy (RP). We tested whether the risk of postoperative urinary incontinence (UIC) and erectile dysfunction (ED) after RP could be further substantiated in such patients. MATERIALS AND METHODS: We tested the effect of the following variables on UIC and ED rates 1 year after RP: residual prostate volume after transurethral desobstruction, the time from transurethral desobstruction to RP, the type of transurethral desobstruction (TURP vs. laser enucleation), age, and nerve-sparing surgery (yes vs. no). UIC was defined as usage of any pad except a safety pad. ED was defined as no sexual intercourse possible. RESULTS: Overall, 216 patients treated with RP between 2010 and 2019 in a tertiary care center were evaluated. All patients had previously undergone transurethral desobstruction. Regarding UIC analyses, only time from transurethral desobstruction to RP significantly influenced UIC rates (p = 0.003). Regarding ED rates, none of the tested variables reached statistical significance. CONCLUSION: The risk of UIC and ED after RP is substantial in men who had previously undergone transurethral desobstruction. The time from transurethral desobstruction to RP significantly impacts on the postoperative UIC rates. This observation should be further explored in future studies.

Tumor-Associated Release of Prostatic Cells into the Blood after Transrectal Ultrasound-Guided Biopsy in Patients with Histologically Confirmed Prostate Cancer.

BACKGROUND: Transrectal ultrasound-guided prostate biopsy (TRUS) is a standard procedure for prostate cancer diagnosis. Because prostate cancer is a multifocal disease in many patients, multiple sampling (n ≥ 10) is required, which may bear the risk of systemic spread of cancer cells. DESIGN: Using the standardized CellSearch® system that allows for the detection of single epithelial cell adhesion molecule-positive circulating tumor cells (CTCs) in blood, we investigated whether prostate biopsy is associated with release of prostatic tumor cells into the circulation. Peripheral blood was obtained before and within 30 min after performing prostate biopsy from 115 men with increased serum prostate-specific antigen. RESULTS: The number of CTCs significantly increased after biopsy in men with histologically confirmed prostate cancer (odds ratio, 7.8; 95% CI, 4.8-12.8), whereas no biopsy-related changes could be detected in men without confirmed prostate cancer. Multivariable analysis showed that biopsy-related increase of CTCs was significantly correlated with a worse progression-free survival (hazard ratio, 12.4; 95% CI, 3.2-48.6) within the median follow-up of 41 months. CONCLUSIONS: Prostate biopsies may lead to a tumor-associated release of CTCs into the blood circulation. Larger confirmatory trials with longer follow-up periods are required before any change in clinical practice can be recommended.

Leydig-cell tumour of the testis: retrospective analysis of clinical and therapeutic features in 204 cases.

PURPOSE: Leydig-cell tumours (LCT) of the testis are poorly understood clinically. The aim of this report is to analyse the clinical characteristics of LCT in a large patient sample and to compare these findings with corresponding data of germ-cell tumours (GCT). METHODS: In a sample of 208 patients treated during 1995-2017 in 33 institutions, the following characteristics were registered: age, presenting symptoms, primary tumour size, testis-sparing surgery (TSS) or orchiectomy, malignancy, laterality, medical history, and outcome. Data analysis included descriptive statistical methods and logistic regression analysis. RESULTS: The ratio LCT:GCT is 1:23 (4.4%). The findings are as follows: median age 41 years, undescended testis 8%, bilateral LCTs 3%, malignant LCT 2.5%, contralateral GCT 2.5%, incidental detection 28%, scrotal symptoms 43%, infertility 18%, elevated estradiol levels 29%. TSS was performed in 56% with no local relapse. Of the patients with malignant LCT, one was cured through surgery. CONCLUSION: LCT is rare, with a relative frequency (relative to GCT) of 1:23. Malignancy is found in 2.5%. LCT and GCT share a number of clinical features, e.g. bilaterality, history of undescended testis, and presenting age. TSS is safe in benign LCT. Surgery is the treatment of choice in malignant LCT.

Major complications of post-chemotherapy retroperitoneal lymph node dissection in a contemporary cohort of patients with testicular cancer and a review of the literature.

BACKGROUND: Post-chemotherapy retroperitoneal lymph node dissection (pc-RPLND) is one cornerstone in the clinical management of patients with nonseminomatous testicular germ cell tumours (GCT). A wide range of complication rates in this type of surgery is reported so far. We retrospectively evaluated the frequency of major complications by using the Clavien-Dindo classification and analysed the influence of various clinical factors on complication rates in pc-RPLND. METHODS: We retrospectively analysed 146 GCT patients undergoing pc-RPLND. Complications of grade III-V according to the Clavien-Dindo classification occurring within 30 days after surgery were registered along with the following clinical factors: age, body mass index (BMI), duration of surgery, number of anatomic fields resected, side of primary tumour, histology of surgical specimen, histology of primary tumour, and total dose of cisplatin applied prior to surgery. For comparison, we also evaluated 35 chemotherapy-naïve patients with primary RPLND and 19 with laparoscopic RPLND. We analysed types and frequencies of the various complications as well as associations with clinical factors using descriptive statistical methods. RESULTS: A total of 14.4% grade III-IV complications were observed in pc-RPLND, and 8.6% and 5.3% in primary and in laparoscopic RPLND, respectively. There was no perioperative mortality. Lymphocele was the most frequent adverse event (16% of grade III-IV complications). Operation time > 270 min (p = 0.001) and vital cancer in the resected specimen (p = 0.02) were significantly associated with higher complication rates. Left-sided resection fields involved two-fold higher complication rates, barely missing statistical significance (p = 0.06). CONCLUSIONS: Pc-RPLND involves a grade III-V complication rate of 14.4%. Prolonged operation time and vital cancer in the residual mass are significantly associated with higher complication rates. The Clavien-Dindo classification system may allow inter-observer variation in rating complication grades, which may represent one reason for the wide range of reported RPLND complication rates. RPLND represents major surgery and surgeons active in this field must be competent to manage adverse events.

A comparative study of robot-assisted and open radical prostatectomy in 10 790 men treated by highly trained surgeons for both procedures.

OBJECTIVE: To compare oncological, functional and surgical outcomes of open retropubic radical prostatectomy (ORP) vs robot-assisted laparoscopic radical prostatectomy (RARP). PATIENTS AND METHODS: We identified 10 790 consecutive treated patients within our prospective database (2008-2016) who underwent either ORP (7007 patients) or RARP (3783). All procedures were performed by seven highly trained surgeons performing both surgical approaches regularly. Oncological (48-month biochemical recurrence [BCR] rate), functional (urinary continence, erectile function), and surgical outcomes (rate of nerve-sparing [NS] procedures, lymph node yield, surgical margin [SM] status, length of hospital stay [LOS], operation time, blood loss, transfusion rate, time to catheter removal) were assessed. Kaplan-Meier, multivariable Cox and logistic regression models were used to test for BCR and functional outcome differences. RESULTS: No statistically significant difference regarding oncological outcome distinguished between ORP vs RARP. For functional outcomes, the 1-week continence rates were higher in the ORP group (25.8% vs 21.8%, P < 0.001). At 3 months, no statistically significant differences were observed. At 12 months, continence rates were modestly higher in the RARP group (90.3% vs 88.8%, P = 0.01). This effect was no longer observed after stratification for age-groups. The 12-month potency rates were similar in ORP vs RARP (80.3% vs 83.6%, P = 0.33). For surgical outcomes, there was no significant difference in the rates of NS procedures, lymph node yield, SM status, and LOS. Conversely, operation time was shorter in ORP, and blood loss, transfusion rates and time to catheter removal were significantly lower in RARP. CONCLUSIONS: Both surgical approaches, performed in a high-volume centre by the same surgeons, achieve excellent, comparable oncological and functional outcomes. However, a modest advantage for RARP for surgical outcomes was observed, most likely attributable to its minimally invasive nature, and better teaching capabilities. Consequently, more than the surgical approach itself, the well-trained surgeon remains the most important factor to achieve satisfactory outcomes.

Diagnostic accuracy of third-generation dual-source dual-energy CT: a prospective trial and protocol for clinical implementation.

PURPOSE: Uric acid (UA) calculi can be referred to chemolitholysis rather than invasive treatment. Dual-energy computed tomography (DECT) may be able to distinguish between UA and non-UA (NUA) calculi. The aim of this study was to evaluate the validity of third-generation DECT for the first time and to investigate whether combining DECT with clinical parameters can increase its predictive accuracy. MATERIALS AND METHODS: All patients who presented to our emergency department between January 2015 and March 2017 with urinary stones were prospectively included in this observational study and underwent DECT with subsequent interventional stone removal. Stone composition was analyzed using infrared spectrometry as the gold standard. Predictive accuracy of DECT and clinical covariates was computed by assessing univariate and multivariate areas under the curve (AUCs). RESULTS: Of 84 patients with 144 urinary stones, 10 (11.9%) patients had UA stones according to infrared spectrometry, and the remaining stones were NUA or mixed stones. DECT had a positive predictive value of 100% and a negative predictive value of 98.5% for UA stones. The AUC for urine pH alone was 0.71 and 0.97 for DECT plus urine pH. No UA stones were found in patients with a urine pH above > 5.5. Mean DLP was 225.15 ± 128.60 mGy*cm and mean effective dose was 3.38 ± 1.93 mSv. CONCLUSIONS: DECT is a safe method for assigning patients to oral chemolitholysis. Clinical preselection of patients based on urinary pH (< 6.0) leads to a more liable use of DECT. Third-generation DECT needs significant lower radiation doses compared to previous generations.

Perioperative management of direct oral anticoagulants in patients undergoing radical prostatectomy: results of a prospective assessment.

INTRODUCTION AND OBJECTIVES: In the perioperative setting, temporary interruption of direct oral anticoagulants (DOACs) is recommended. However, the safety of these recommendations is based on non-urological surgical experiences. Our objective was to verify the safety of these recommendations in patients undergoing radical prostatectomy (RP). MATERIALS AND METHODS: Patients regularly receiving a DOAC and scheduled for RP at our institution were prospectively assessed. DOAC intake was usually stopped 48 h before surgery without any preoperative bridging therapy. Postoperatively, patients received risk-adapted low-molecular weight heparin (LMWH). On the third day after unremarkable RP, DOAC intake was restarted and the administration of LMWH was stopped. We assessed perioperative outcomes and 30-day morbidity. RESULTS: Thirty-two consecutive patients receiving DOAC underwent RP at our institution between 12/2017 and 07/2018. Time of surgery (median, 177 min) and intraoperative blood loss (median, 500 mL) were unremarkable. DOACs were restarted on the third postoperative day in 30 patients (94%). No patient had a significant hemoglobin level reduction after DOAC restart. Overall, 28% of patients experienced complications within 30 days after surgery. Most of which were minor (Clavien ≤ 2), three patients (9%), however, had Clavien ≥ 3 complications. CONCLUSION: Our report is the first to prospectively assess current guideline recommendations regarding DOAC restarting after major urological surgery. RP can safely be performed, if DOACs are correctly paused before surgery. Moreover, in case of an uneventful postoperative clinical course, DOACs can be safely restarted on the third postoperative day. A 9% Clavien ≥ 3 30-day morbidity warrants attention and should be further explored in future studies.

Multicenter evaluation of guideline adherence for pelvic lymph node dissection in patients undergoing open retropubic vs. laparoscopic or robot assisted radical prostatectomy according to the recent German S3 guideline on prostate cancer.

PURPOSE: Pelvic lymph node dissection (PLND) is recommended for patients with prostate cancer (PCa) and significant risk for nodal metastases. This study aimed to assess guideline adherence regarding PLND according to the German S3 guideline as example for a national but highly used guideline on prostate cancer and to compare the rate of complications different approaches for radical prostatectomy (RP). METHODS: Patients undergoing open (RRP), laparoscopic (LARP) or robot-assisted (RARP) RP in six centers in Germany and Austria were included. The primary endpoint was the total number of removed lymph nodes (LN) between the different surgical approaches according to recent guideline recommendations. Secondary endpoints were the number of patients undergoing a sufficient PLND, defined as a removal of at least 10 LN and associated complication rates. RESULTS: 2634 patients undergoing RP were included (RRP: 66%, RARP/LARP: 34%). PLND was performed in 88% (RRP: 88.5%, RARP/LARP: 86.8%, p = 0.208). In intermediateor high risk PCa, PLND was performed in 97.2% (RRP: 97.7%, RARP/LARP: 96.2, p = 0.048). Of those, the mean number of LN was 19 (RRP: 19 vs. RARP/LARP: 17, p < 0.005) and sufficient PLND was observed in 84.6% of RRP compared to 77.2% of RARP/LARP (p < 0.005). Symptomatic lymphoceles requiring surgical treatment occurred more often in RRP than in RARP/LARP (4.0% vs. 1.6%, p = 0.001). CONCLUSIONS: The general guideline adherence regarding performing PNLD and the LN yield is high, regardless of the surgical approach. As expected, lymph node yield was higher when very experienced surgeons conducted the procedure. This should be considered in patients' counseling.

Thromboprophylaxis and the route of administration of chemotherapy in testicular cancer patients in German-speaking countries.

PURPOSE: Due to the excellent cure rates for testicular cancer (TC), focus has shifted towards decreasing therapy-related morbidities. Thrombosis is a frequent complication of cisplatin chemotherapy. Furthermore, the optimal route of administration for chemotherapy is still under debate. The purpose of this study was to assess the patterns of care concerning dosing and duration of thromboprophylaxis currently utilized in TC patients in German-speaking countries as well as the route of chemotherapy administration. METHODS: A standardized questionnaire was sent to all members of the German TC Study Group (GTCSG) and to all the urological university hospitals in Germany. The questionnaire was also sent to the oncologic clinics at those universities where urologists do not administer chemotherapy. RESULTS: The response rate was 87% (55/63). Prophylactic anticoagulation with low-molecular-weight heparin (LMWH) was administered in 94% of the clinics. The dosing of LMWH was prophylactic (85%), high prophylactic (adjusted to bodyweight) (7%), or risk adapted (9%). After completion of chemotherapy, anticoagulation was continued in 15 clinics (33%) for 2 to 24 weeks, while the remainder stopped the LMWH upon cessation of chemotherapy. Chemotherapy was administered via central venous access in 59%, peripheral IV in 27%, or both in 14% of the clinics. CONCLUSIONS: Most of the institutions performed some form of thromboprophylaxis, although the modes of application varied by institution type and amongst the urologists and oncologists. Prospective studies are needed to evaluate the incidence, date of occurrence, and risk factors of venous thrombosis during TC chemotherapy to provide a recommendation concerning prophylactic anticoagulation.

Testicular Germ-Cell Tumours: A Descriptive Analysis of Clinical Characteristics at First Presentation.

INTRODUCTION: Clinical characteristics of testicular germ cell tumours (GCTs) apparently change over time, and some vary geographically. The aim of this study is to document the clinical profile of contemporary GCT patients. PATIENTS AND METHODS: Four hundred twenty-two Caucasian GCT-patients treated in one German centre during 2000-2017, were analysed in terms of patient-age, laterality, histology, tumour-size, clinical stages (CS), pathological (pT)-stages and serum biomarker expression. The results were analysed descriptively and compared with the literature. RESULTS: Median age was 36 years and 60.2% had seminoma. Βeta-human chorionic gonadotropin was expressed in 37.9% and alpha Fetoprotein in 25.6%. CS1 presenting stage was 66.6% of all GCT patients, 79.1% in seminoma, and 47.6% in nonseminoma. Tumour size was significantly associated with pT-stages and CS. Patients >50 years had significantly more seminoma (77.6%) than younger ones (57.9%). Comparison with literature data revealed a shifting towards higher age, lower CS, higher proportion of seminoma and striking differences of characteristics among geographic regions. CONCLUSIONS: A typical contemporary clinical profile of testicular GCTs is presented in this study. Median age, relative incidence of seminoma and proportion of CS1 appear to be increasing over time. Striking differences among ethnic groups regarding the characteristics of GCT require further investigation.

Evaluating Guideline Adherence for T1 Bladder Cancer Treatment and Surveillance: A Retrospective German Multicenter Observation.

INTRODUCTION: To mirror guideline-adherence for pT1 bladder cancer treatment in Northern Germany. MATERIALS AND METHODS: Overall, 111 patients with pT1 diagnosis were treated at 4 institutions. Guideline-adherence was defined as repeat resection, instillation, and quarterly cystoscopy. Patient characteristics and pathological parameters were assessed. We summarized patients using descriptive analyses and evaluated guideline-adherence within selected subgroups. We created a multivariable model to identify predictors of guideline-adherence. RESULTS: Median age was 75 years (range 39-94 years), multifocal tumors were found in 44.1%, early instillation was performed in 33.3%, and repeat resection was performed in 77.5%. Of 62.2% who underwent instillation, 59.4% received BCG, while 40.6% received Mitomycin C or other agents. Cystoscopic follow-up was performed in 81.8%. Guideline-adherence was met in 56.8%. Patients aged below the median met adherence metrics more often compared to those above the median (66.7 vs. 46.3%; p = 0.030). Men more frequently met adherence metrics compared to women (62.1 vs. 37.5%; p = 0.038). More patients with multifocal tumors met all 3 adherence metrics (69.4 vs. 48.0%; p = 0.050), as compared to those with unifocal lesions. In multivariable analyses, age-adjusted comorbidity (OR 0.75; 95% CI 0.59-0.94; p = 0.011) and multifocality (OR 2.62; 95% CI 1.09-6.27; p = 0.031) were predictors of guideline-adherence. CONCLUSIONS: We found non-adherence in more than one-third of patients and disparities among patients of different age and according to tumor focality. Larger samples and prospective studies are needed to delineate and eradicate treatment disadvantages in these high-risk patients.

Incidence of prostate cancer in hypogonadal men receiving testosterone therapy: observations from 5-year median followup of 3 registries.

PURPOSE: Although there is no evidence that testosterone therapy increases the risk of prostate cancer, there is a paucity of long-term data. We determined whether the incidence of prostate cancer is increased in hypogonadal men receiving long-term testosterone therapy. MATERIALS AND METHODS: In 3 parallel, prospective, ongoing, cumulative registry studies 1,023 hypogonadal men received testosterone therapy. Two study cohorts were treated by urologists (since 2004) and 1 was treated at an academic andrology center (since 1996). Patients were treated when total testosterone was 12.1 nmol/l or less (350 ng/dl) and symptoms of hypogonadism were present. Maximum followup was 17 years (1996 to 2013) and median followup was 5 years. Mean baseline patient age in the urological settings was 58 years and in the andrology setting it was 41 years. Patients received testosterone undecanoate injections in 12-week intervals. Pretreatment examination of the prostate and monitoring during treatment were performed. Prostate biopsies were performed according to EAU guidelines. RESULTS: Numbers of positive and negative biopsies were assessed. The incidence of prostate cancer and post-prostatectomy outcomes was studied. A total of 11 patients were diagnosed with prostate cancer in the 2 urology settings at proportions of 2.3% and 1.5%, respectively. The incidence per 10,000 patient-years was 54.4 and 30.7, respectively. No prostate cancer was reported by the andrology center. Limitations are inherent in the registry design without a control group. CONCLUSIONS: Testosterone therapy in hypogonadal men does not increase the risk of prostate cancer. If guidelines for testosterone therapy are properly applied, testosterone treatment is safe in hypogonadal men.

Preferences in the management of high-risk prostate cancer among urologists in Europe: results of a web-based survey.

OBJECTIVE: To explore preferences in the management of patients with newly diagnosed high-risk prostate cancer (PCa) among urologists in Europe through a web-based survey. MATERIALS AND METHODS: A web-based survey was conducted between 15 August and 15 September 2013 by members of the Prostate Cancer Working Group of the Young Academic Urologists Working Party of the European Association of Urology (EAU). A specific, 29-item multiple-choice questionnaire covering the whole spectrum of diagnosis, staging and treatment of high-risk PCa was e-mailed to all urologists included in the mailing list of EAU members. Europe was divided into four geographical regions: Central-Eastern Europe (CEE), Northern Europe (NE), Southern Europe (SE) and Western Europe (WE). Descriptive statistics were used. Differences among sample segments were obtained from a z-test compared with the total sample. RESULTS: Of the 12,850 invited EAU members, 585 urologists practising in Europe completed the survey. High-risk PCa was defined as serum PSA ≥20 ng/mL or clinical stage ≥ T3 or biopsy Gleason score ≥ 8 by 67% of responders, without significant geographical variations. The preferred single-imaging examinations for staging were bone scan (74%, 81% in WE and 70% in SE; P = 0.02 for both), magnetic resonance imaging (53%, 72% in WE and 40% in SE; P = 0.02 and P = 0.01, respectively) and computed tomography (45%, 60% in SE and 23% in WE; P = 0.01 for both). Pre-treatment predictive tools were routinely used by 62% of the urologists, without significant geographical variations. The preferred treatment was radical prostatectomy as the initial step of a multiple-treatment approach (60%, 40% in NE and 70% in CEE; P = 0.02 and P < 0.01, respectively), followed by external beam radiation therapy with androgen deprivation therapy (29%, 45% in NE and 20% in CEE; P = 0.01 and P = 0.02, respectively), and radical prostatectomy as monotherapy (4%, 7% in WE; P = 0.04). When surgery was performed, the open retropubic approach was the most popular (58%, 74% in CEE, 37% in NE; P < 0.01 for both). Pelvic lymph node dissection was performed by 96% of urologists, equally split between a standard and extended template. There was no consensus on the definition of disease recurrence after primary treatment, and much heterogeneity in the administration of adjuvant and salvage treatments. CONCLUSION: With the limitation of a low response rate, the present study is the first survey evaluating preferences in the management of high-risk PCa among urologists in Europe. Although the definition of high-risk PCa was fairly uniform, wide variations in patterns of primary and adjuvant/salvage treatments were observed. These differences might translate into variations in quality of care with a possible impact on ultimate oncological outcome.

The oncologic role of local treatment in primary metastatic prostate cancer.

PURPOSE: To determine the oncologic benefit or otherwise of local treatment of the prostate in patients with primary metastatic prostate cancer. METHODS: A review of the literature was performed in April 2014 using the Medline/PubMed database. Studies were identified using the search terms "prostate cancer," "metastatic," "metastasis," "high risk," "radiation therapy," "radiotherapy" and "prostatectomy" from 1990 until April, 2014. Articles were also identified through searches of references of these articles. RESULTS: Retrospective series and population-based data suggest that the use of local treatment of the prostate in patients with primary metastatic prostate cancer may improve cancer-specific survival and overall survival compared with treating these patients with androgen deprivation therapy alone. The clinical outcome in metastatic prostate cancer is largely determined by the extent of lymph node involvement and overall metastatic burden. Contemporary data are lacking to recommend one alternative of local therapy (radiotherapy or radical prostatectomy) over the other. The primary limitation of this literature review is the lack of published randomized trial assessing the role of local treatment in addition to systemic therapy. CONCLUSIONS: Local treatment appears to improve oncologic outcomes in metastatic prostate cancer patients. Nevertheless, due to the lack of high-quality evidence, its role needs to be confirmed in future prospective trials. The selection of ideal candidates and optimal treatment alternative (radiotherapy, radical prostatectomy or other) warrants further investigation.

A tertiary Gleason pattern in the prostatectomy specimen and its association with adverse outcome after radical prostatectomy.

PURPOSE: The prognostic significance of a tertiary Gleason pattern in the radical prostatectomy specimen is controversial. We tested the impact of a tertiary Gleason pattern on adverse histopathological features and biochemical recurrence rates after radical prostatectomy. MATERIALS AND METHODS: We assessed data on 11,226 consecutive patients treated with radical prostatectomy at our institution between June 2007 and February 2013. We compared 2,396 patients with (22.4%) and 8,260 without (77.5%) a tertiary Gleason pattern for adverse histopathological features (extraprostatic extension, seminal vesicle invasion, positive surgical margins and lymph node invasion) using the chi-square test. The effect of a tertiary Gleason pattern on biochemical recurrence was tested in univariable and multivariable models. Subanalyses were then done for different radical prostatectomy Gleason groups (6 or less, 3 + 4 and 4 + 3). RESULTS: A tertiary Gleason pattern was statistically significantly associated with all evaluated histopathological parameters (each p <0.001). It was an independent predictor of biochemical recurrence (HR 1.43, p <0.001). On subanalysis only a tertiary Gleason pattern independently predicted biochemical recurrence in the patient cohort with a radical prostatectomy Gleason score of 3 + 4 and 4 + 3. However, it failed to attain independent predictor status in patients with a radical prostatectomy Gleason score of 6 or less. CONCLUSIONS: A tertiary Gleason pattern is a significant and independent predictor of biochemical recurrence after radical prostatectomy with the strongest prognostic effect in cases with Gleason scores 3 + 4 and 4 + 3. Therefore, a tertiary Gleason pattern should be recorded in the pathological report.

Outcomes after recto-anastomosis fistula repair in patients who underwent radical prostatectomy for prostate cancer.

OBJECTIVES: To assess fistula recurrence rate and health-related quality of life (HRQL) after repair, as well as the impact on continence and erection in patients with recto-anastomotic fistula after radical prostatectomy (RP). In recent publications, the numbers of cases of recto-urinary fistulae after RP are relatively small. Success rates at fistula closure are good; however, data about functional outcomes and HRQL are more restricted. PATIENTS AND METHODS: A retrospective study of patients treated for recto-urethral fistulae after RP between 1993 and 2008. All 17 patients were assessed for fistula recurrence in 2007 and received a standardised non-validated questionnaire to assess HRQL in 2011; furthermore, a patient's chart review was performed. SURGICAL TECHNIQUE: fistula closure was abdominal in 10 patients, perineal in five and combined abdominal and perineal in two, some with tissue interposition. RESULTS: In 2007, follow-up was available for 14 patients, one was deceased and two were lost to follow-up. The mean follow-up was 73.3 months and the mean patient age was 63 years. In two of the 17 patients, rectal injury during the initial surgery was reported; another three had undergone adjuvant radiation therapy (18%). In 2011, another two patients were deceased; the mean (range) follow-up was 99.5 (44-184) months. There was a great improvement in HRQL as compared with before surgery in seven of the 12 evaluable patients, a slight improvement in one and no change in three. In all, eight of the 12 patients were very satisfied with the surgery and four were satisfied. CONCLUSION: Perineal or abdominal fistula repair yields excellent success rates and high patient satisfaction. However, urinary incontinence can be found in some patients postoperatively, requiring further treatment.

Open and robot-assisted radical retropubic prostatectomy in men receiving ongoing low-dose aspirin medication: revisiting an old paradigm?

OBJECTIVE: To assess blood loss, transfusion rates and 90-day complication rates in patients receiving ongoing 100 mg/day aspirin medication and undergoing open radical prostatectomy (RP) or robot-assisted RP (RARP). PATIENTS AND METHODS: Between February 2010 and August 2011, 2061 open RPs and 400 RARPs were performed. All patients received low-molecular-weight heparin for thrombembolism prophylaxis. Aspirin intake during surgery was recorded in 137 patients (5.5%). Descriptive statistics and multivariable analyses after propensity-score matching for balancing potential differences in patients with and without aspirin medication were used to assess the risk of blood loss above the median in patients undergoing open RP or RARP. RESULTS: The median blood loss in the open RP cohort with and without aspirin medication was 750 and 700 mL, respectively, and in the RARP cohort it was 200 and 150 mL, respectively. Within the same cohorts, transfusions were administered in 21 and 8% and 0 and 1% of patients, respectively. The 90-day complication rates in patients with ongoing aspirin medication were 5.8, 4.4, 7.3 and 0% for Clavien grades I, II, III and IV complications, respectively. In multivariable analyses and after propensity-score matching, prostate volume (odds ratio 1.03; 95% CI 1.02-1.04; P < 0.01) but not ongoing aspirin medication achieved independent predictor status for the risk of blood loss above the median. CONCLUSIONS: Major surgery such as open RP and RARP can be safely performed in patients with ongoing aspirin medication without greater blood loss. Higher 90-day complication rates were not detected in such patients. Differences in transfusion rates between the groups receiving and not receiving ongoing aspirin medication may be explained by a higher proportion of patients with coronary artery disease in the group receiving ongoing aspirin medication. This comorbidity may result in a higher peri-operative threshold for allogenic blood transfusion.

The Barbagli technique: 3-year experience with a modified approach.

UNLABELLED: What's known on the subject? and What does the study add? Urethral strictures can be treated by various methods, e.g. dilatation and endoscopic treatment, as well as with open surgery. However, transurethral treatment shows low long-time success rates, while open urethral reconstruction yields good long-term results. One of the standard procedures to reconstruct the strictured penile urethra is the Barbagli technique, which was introduced in 1996. However, a potential drawback of this technique is the suturing of the urethral margins to the second side of the graft, because the buccal mucosa is already fixed to the corpus cavernosum and the last line is sutured in the back side of the urethra out of sight. The present study aims to assess whether the functional results are compromised by a modified Barbagli technique, which enables a better visualisation of the mucosal margins while making the anastomosis, simplifying the original technique. OBJECTIVE: To evaluate stricture recurrence rate as well as the satisfaction with the surgery of patients treated with a modified Barbagli technique published by our study group in 2009. PATIENTS AND METHODS: Retrospective analysis by patient's chart review and unvalidated standardised questionnaire of patients treated by the modified Barbagli technique for urethral stricture between May 2008 and September 2010. In all, 22 patients were treated with the modified Barbagli technique for urethral stricture during this time, and 18 patients were available for follow-up. Previous surgeries, recurrence rate, complications, incontinence, erectile function, satisfaction with the surgery, and oral numbness were assessed. As described in the original technique, also in the modified technique the access to the urethra is achieved through a midline incision. Subsequently, the urethra is completely mobilised. However, it is then rotated 180 ° using stay sutures. Afterwards, the buccal mucosa is sutured into the opened urethra on both sides under vision, giving free access to the margins. Once the buccal mucosa is completely sutured in, the urethra is back-rotated using stay sutures and the margin of the buccal mucosa and the urethra is sutured to the tunica albuginea, stretching and supporting the buccal mucosa. RESULTS: Follow-up was available for 18 patients with a mean (range) age of 67.5 (27-74) years. Open previous surgeries had been performed in 27.8% and transurethral surgeries in 72.2%. The mean (range) length of the oral mucosa graft was 7.8 (2.5-13) cm and the mean operative duration was 106 (73-193) min. The success rate was 83.2%; there was no de novo erectile dysfunction and no relevant penile curvature. There was oral numbness in two patients (9%). None of the recurrence-free patients (83.3%) were dissatisfied with the surgery. CONCLUSIONS: The technique simplifies the original technique without compromising the functional results. The modification of the technique enables a better visualisation of the mucosal margins while making the anastomosis, simplifying the original technique. The success rate was comparable with the original technique and patient satisfaction with the surgery was high.
