RÉSUMÉ

BACKGROUND: Biobanking of prostate carcinoma is particularly challenging due to the actual cancer within the organ often without clear margins. Frozen sections are to date the only way to examine the biobank material for its tumor content. We used ex vivo fluorescence confocal microscopy (FCM) to analyze biobank samples prior to cryoasservation. METHODS: 127 punch biopsies were acquired from prostatectomy-specimens from 40 patients. These biopsies were analyzed with a Vivascope 2500-G4 prior to their transfer to the biobank. In difficult cases, larger samples of the prostatectomy specimens were FCM scanned in order to locate tumor foci. After patient acquisition, all samples were taken from the biobank and analyzed. We compared the results of the FCM examinations with the results of conventional histology and measured the DNA content. RESULTS: With upstream FCM, the tumor content of biobank samples could be determined with high confidence. The detection rate of representative biobank samples was increased due to the rapid feedback. The biobank samples were suitable for further molecular analysis. CONCLUSION: FCM allows for the first time lossless microscopic analysis of biobank samples prior to their cryoasservation and guarantees representative tumor and normal tissue for further molecular analysis.

RÉSUMÉ

INTRODUCTION: Since the beginning of the pandemic in 2020, COVID-19 has changed the medical landscape. International recommendations for localized prostate cancer (PCa) include deferred treatment and adjusted therapeutic routines. MATERIALS AND METHODS: To longitudinally evaluate changes in PCa treatment strategies in urological and radiotherapy departments in Germany, a link to a survey was sent to 134 institutions covering two representative baseline weeks prior to the pandemic and 13 weeks from March 2020 to February 2021. The questionnaire captured the numbers of radical prostatectomies, prostate biopsies and case numbers for conventional and hypofractionation radiotherapy. The results were evaluated using descriptive analyses. RESULTS: A total of 35% of the questionnaires were completed. PCa therapy increased by 6% in 2020 compared to 2019. At baseline, a total of 69 radiotherapy series and 164 radical prostatectomies (RPs) were documented. The decrease to 60% during the first wave of COVID-19 particularly affected low-risk PCa. The recovery throughout the summer months was followed by a renewed reduction to 58% at the end of 2020. After a gradual decline to 61% until July 2020, the number of prostate biopsies remained stable (89% to 98%) during the second wave. The use of RP fluctuated after an initial decrease without apparent prioritization of risk groups. Conventional fractionation was used in 66% of patients, followed by moderate hypofractionation (30%) and ultrahypofractionation (4%). One limitation was a potential selection bias of the selected weeks and the low response rate. CONCLUSION: While the diagnosis and therapy of PCa were affected in both waves of the pandemic, the interim increase between the peaks led to a higher total number of patients in 2020 than in 2019. Recommendations regarding prioritization and fractionation routines were implemented heterogeneously, leaving unexplored potential for future pandemic challenges.

RÉSUMÉ

OBJECTIVES: To evaluate the postoperative complication and mortality rate following laparoscopic radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) in octogenarians. PATIENTS AND METHODS: We conducted a retrospective analysis comparing postoperative complication and mortality rates depending on age in a consecutive series of 1890 patients who underwent RARC with ICUD for bladder cancer between 2004 and 2018 in 10 European centres. Outcomes of patients aged <80 years and those aged ≥80 years were compared with regard to postoperative complications (Clavien-Dindo grading) and mortality rate. Cancer-specific mortality (CSM) and other-cause mortality (OCM) after surgery were calculated using the non-parametric Aalen-Johansen estimator. RESULTS: A total of 1726 patients aged <80 years and 164 aged ≥80 years were included in the analysis. The 30- and 90-day rate for high-grade (Clavien-Dindo grades III-V) complications were 15% and 21% for patients aged <80 years compared to 11% and 13% for patients aged ≥80 years (P = 0.2 and P = 0.03), respectively. In a multivariable logistic regression analysis adjusting for pre- and postoperative variables, age ≥80 years was not an independent predictor of high-grade complications (odds ratio 0.6, 95% confidence interval 0.3-1.1; P = 0.12). The non-cancer-related 90-day mortality was 2.3% for patients aged ≥80 years and 1.8% for those aged <80 years, respectively (P = 0.7). The estimated 12-month CSM and OCM rates for those aged <80 years were 8% and 3%, and for those aged ≥80 years, 15% and 8%, respectively (P = 0.009 and P < 0.001). CONCLUSIONS: The minimally invasive approach to RARC with ICUD for bladder cancer in well-selected elderly patients (aged ≥80 years) achieved a tolerable high-grade complication rate; the 90-day postoperative mortality rate was driven by cancer progression and the non-cancer-related rate was equivalent to that of patients aged <80 years. However, an increased OCM rate in this elderly group after the first year should be taken into account. These results will support clinicians and patients when balancing cancer-related vs treatment-related risks and benefits.

RÉSUMÉ

INTRODUCTION: After the outbreak of COVID-19 unprecedented changes in the healthcare systems worldwide were necessary resulting in a reduction of urological capacities with postponements of consultations and surgeries. MATERIAL AND METHODS: An email was sent to 66 urological hospitals with focus on robotic surgery (RS) including a link to a questionnaire (e.g. bed/staff capacity, surgical caseload, protection measures during RS) that covered three time points: a representative baseline week prior to COVID-19, the week of March 16th-22nd and April 20th-26th 2020. The results were evaluated using descriptive analyses. RESULTS: 27 out of 66 questionnaires were analyzed (response rate: 41%). We found a decrease of 11% in hospital beds and 25% in OR capacity with equal reductions for endourological, open and robotic procedures. Primary surgical treatment of urolithiasis and benign prostate syndrome (BPS) but also of testicular and penile cancer dropped by at least 50% while the decrease of surgeries for prostate, renal and urothelial cancer (TUR-B and cystectomies) ranged from 15 to 37%. The use of personal protection equipment (PPE), screening of staff and patients and protection during RS was unevenly distributed in the different centers-however, the number of COVID-19 patients and urologists did not reach double digits. CONCLUSION: The German urological landscape has changed since the outbreak of COVID-19 with a significant shift of high priority surgeries but also continuation of elective surgical treatments. While screening and staff protection is employed heterogeneously, the number of infected German urologists stays low.

RÉSUMÉ

Recurrence following radical cystectomy often occurs early, with >80% of recurrences occurring within the first 2 yr. Debate remains as to whether robot-assisted radical cystectomy (RARC) negatively impacts early recurrence patterns because of inadequate resection or pneumoperitoneum. We report early recurrence patterns among 717 patients who underwent RARC with intracorporeal urinary diversion at nine different institutions with a minimum follow-up of 12 mo. Clinical, pathologic, radiologic, and survival data at the latest follow-up were collected. Recurrence-free survival (RFS) estimates were generated using the Kaplan-Meier method, and Cox regression models were built to assess variables associated with recurrence. RFS at 3, 12, and 24 mo was 95.9%, 80.2%, and 74.6% respectively. Distant recurrences most frequently occurred in the bones, lungs, and liver, and pelvic lymph nodes were the commonest site of local recurrence. We identified five patients (0.7%) with peritoneal carcinomatosis and two patients (0.3%) with metastasis at the port site (wound site). We conclude that unusual recurrence patterns were not identified in this multi-institutional series and that recurrence patterns appear similar to those in open radical cystectomy series. PATIENT SUMMARY: In this multi-institutional study, bladder cancer recurrences following robotic surgery are described. Early recurrence rates and locations appear to be similar to those for open radical cystectomy series.

RÉSUMÉ

CONTEXT: Radical cystectomy (RC) is associated with frequent morbidity and prolonged length of stay (LOS) irrespective of surgical approach. Increasing evidence from colorectal surgery indicates that minimally invasive surgery and enhanced recovery programmes (ERPs) can reduce surgical morbidity and LOS. ERPs are now recognised as an important component of surgical management for RC. However, there is comparatively little evidence for ERPs after robot-assisted radical cystectomy (RARC). Due to the multimodal nature of ERPs, they are not easily validated through randomised controlled trials. OBJECTIVE: To provide a European Association of Urology (EAU) Robotic Urology Section (ERUS) policy on ERPs to guide standardised perioperative management of RARC patients. EVIDENCE ACQUISITION: The guidance was formulated in four phases: (1) systematic literature review of evidence for ERPs in robotic, laparoscopic, and open RC; (2) an online questionnaire survey formulated and sent to ERUS Scientific Working Group members; (3) achievement of consensus from an expert panel using the Delphi process; and (4) a standardised reporting template to audit compliance and outcome designed and approved by the committee. EVIDENCE SYNTHESIS: Consensus was reached in multiple areas of an ERP for RARC. The key principles include patient education, optimisation of nutrition, RARC approach, standardised anaesthetic, analgesic, and antiemetic regimens, and early mobilisation. CONCLUSIONS: This consensus represents the views of an expert panel established to advise ERUS on ERPs for RARC. The ERUS Scientific Working Group recognises the role of ERPs and endorses them as standardised perioperative care for patients undergoing RARC. ERPs in robotic surgery will continue to evolve with technological and pharmaceutical advances and increasing understanding of the role of surgery-specific ERPs. PATIENT SUMMARY: There is currently a lack of high-level evidence exploring the benefits of enhanced recovery programmes (ERPs) in patients undergoing robot-assisted radical cystectomy (RARC). We reported a consensus view on a standardised ERP specific to patients undergoing RARC. It was formulated by experts from high-volume RARC hospitals in Europe, combining current evidence for ERPs with experts' knowledge of perioperative care for robotic surgery.

RÉSUMÉ

Peritoneal dissemination of prostate cancer (PCa) with the absence of other metastases is extremely rare. Atypical sites of metastatic disease, for example the peritoneum, are only a recognized finding at autopsy. Herein, we report a case of peritoneal dissemination of a PCa, with the absence of lymph node, skeletal, or visceral metastases in a patient scheduled to undergo robot-assisted laparoscopic prostatectomy.

RÉSUMÉ

PURPOSE: We conducted a prospective study to examine the safety and efficacy of the tricyclic antidepressant amitriptyline in patients with interstitial cystitis (IC). MATERIALS AND METHODS: The study comprised 44 women and 6 men who all met the symptom criteria of the National Institute of Diabetes, Digestive and Kidney Diseases for IC. The patients were randomly assigned to amitriptyline or placebo. Patients were prospectively treated for 4 months with a self-titration protocol that allowed them to escalate drug dosage in 25 mg increments in 1 week-intervals (maximum dosage 100 mg). The change from baseline in the O'Leary-Sant IC symptom and problem index was the primary outcome parameter. Changes in functional bladder capacity and frequency (48-hour voiding log), and intensity of pain and urgency (visual analog scales) were chosen as secondary outcome parameters. RESULTS: Two patients (1 on amitriptyline, 1 on placebo) dropped out of the study due to side effects. Thus, the data of 48 patients (24 patients in each group) were available for evaluation. Mean symptom score decreased from 26.9 to 18.5 in the amitriptyline group compared with 27.6 to 24.1 in the placebo group (p = 0.005). Pain and urgency intensity improved statistically significantly in the amitriptyline group compared with the placebo group (p <0.001). The frequency and functional bladder capacity improved to a much greater degree in the amitriptyline group but the differences were not statistically significant (p = 0.063, p = 0.083). Anticholinergic side effects were reported by all except 2 patients in the amitriptyline group (92%) and by 5 patients in the placebo group (21%). Mouth dryness was the most frequent side effect reported in the amitriptyline group (79%). CONCLUSIONS: Amitriptyline therapy for 4 months is safe and effective for treating IC. A statistically significant change in the symptom score and statistically significant improvement of pain and urgency intensity compared with placebo were observed. Anticholinergic side effects constitute the major drawback of amitriptyline treatment for IC.
