The rapid assessment for prostate imaging and diagnosis (RAPID) prostate cancer diagnostic pathway.

OBJECTIVE: To report outcomes within the Rapid Assessment for Prostate Imaging and Diagnosis (RAPID) diagnostic pathway, introduced to reduce patient and healthcare burdens and standardize delivery of pre-biopsy multiparametric magnetic resonance imaging (MRI) and transperineal biopsy. PATIENTS AND METHODS: A total of 2130 patients from three centres who completed the RAPID pathway (3 April 2017 to 31 March 2020) were consecutively entered as a prospective registry. These patients were also compared to a pre-RAPID cohort of 2435 patients. Patients on the RAPID pathway with an MRI score 4 or 5 and those with PSA density ≥0.12 and an MRI score 3 were advised to undergo a biopsy. Primary outcomes were rates of biopsy and cancer detection. Secondary outcomes included comparison of transperineal biopsy techniques, patient acceptability and changes in time to diagnosis before and after the introduction of RAPID. RESULTS: The median patient age and PSA level were 66 years and 6.6 ng/mL, respectively. Biopsy could be omitted in 43% of patients (920/2130). A further 7.9% of patients (168/2130) declined a recommendation for biopsy. The percentage of biopsies avoided among sites varied (45% vs 36% vs 51%; P < 0.001). In all, 30% (221/742) had a local anaesthetic (grid and stepper) transperineal biopsy. Clinically significant cancer detection (any Gleason score ≥3 + 4) was 26% (560/2130) and detection of Gleason score 3 + 3 alone constituted 5.8% (124/2130); detection of Gleason score 3 + 3 did not significantly vary among sites (P = 0.7). Among participants who received a transperineal targeted biopsy, there was no difference in cancer detection rates among local anaesthetic, sedation and general anaesthetic groups. In the 2435 patients from the pre-RAPID cohor, time to diagnosis was 32.1 days (95% confidence interval [CI] 29.3-34.9) compared to 15.9 days (95% CI 12.9-34.9) in the RAPID group. A total of 141 consecutive patient satisfaction surveys indicated a high satisfaction rate with the pathway; 50% indicated a preference for having all tests on a single day. CONCLUSIONS: The RAPID prostate cancer diagnostic pathway allows 43% of men to avoid a biopsy while preserving good detection of clinically significant cancers and low detection of insignificant cancers, although there were some centre-level variations.

Is the Toxicity of Salvage Prostatectomy Related to the Primary Prostate Cancer Therapy Received?

PURPOSE: To compare the toxicity profile and oncological outcome of salvage radical prostatectomy following focal therapy versus salvage radical prostatectomy after radiation therapies (external beam radiation therapy or brachytherapy). MATERIALS AND METHODS: Data concerning all men undergoing salvage radical prostatectomy for recurrent prostate cancer after either focal therapy, external beam radiation therapy or brachytherapy were retrospectively collected from 4 high volume surgical centers. The primary outcome measure of the study was toxicity of salvage radical prostatectomy characterized by any 30-day postoperative Clavien-Dindo complication rate, 12-month continence rate and 12-month potency rate. The secondary outcome was oncological outcome after salvage radical prostatectomy including positive margin rate and 12-month biochemical recurrence rate. Biochemical recurrence was estimated using Kaplan-Meier methods and significant differences were calculated using a log rank test. Median followup was 29.5 months. RESULTS: Between April 2007 and September 2018, 185 patients underwent salvage radical prostatectomy of whom 95 had salvage radical prostatectomy after focal therapy and 90 had salvage radical prostatectomy after radiation therapy (external beam radiation therapy or brachytherapy). Salvage radical prostatectomy after radiation therapy was associated with a significantly higher 30-day Clavien-Dindo I-IV complication rate (34% vs 5%, p <0.001). At 12 months following surgery, patients undergoing salvage radical prostatectomy after focal therapy had significantly better continence (83% pad-free vs 49%) while potency outcomes were similar (14% vs 11%). Men undergoing salvage radical prostatectomy after radiation therapy had a significantly higher stage and grade of disease together with a higher positive surgical margin rate (37% vs 13%, p=0.001). The 3-year biochemical recurrence after focal therapy was 35% compared to 32% after radiation therapy (p=0.76). In multivariable analysis, men undergoing salvage radical prostatectomy after focal therapy experienced a higher risk of biochemical recurrence (HR 0.36, 95% CI 0.16-0.82, p=0.02). CONCLUSIONS: This multicenter study demonstrates the toxicity of salvage radical prostatectomy in terms of perioperative complications and long-term urinary continence recovery is dependent on initial primary prostate cancer therapy received with men undergoing salvage radical prostatectomy after focal therapy experiencing lower postoperative complication rates and better urinary continence outcomes.

Local anaesthetic transperineal (LATP) prostate biopsy using a probe-mounted transperineal access system: a multicentre prospective outcome analysis.

OBJECTIVES: To assess the feasibility of local anaesthetic transperineal (LATP) technique using a single-freehand transperineal (TP) access device, and report initial prostate cancer (PCa) detection, infection rates, and tolerability. PATIENTS AND METHODS: Observational study of a multicentre prospective cohort, including all consecutive cases. LATP was performed in three settings: (i) first biopsy in suspected PCa, (ii) confirmatory biopsies for active surveillance, and (iii) repeat biopsy in suspected PCa. All patients received pre-procedure antibiotics according to local hospital guidelines. Local anaesthesia was achieved by perineal skin infiltration and periprostatic nerve block without sedation. Ginsburg protocol principles were followed for systematic biopsies including cognitive magnetic resonance imaging-targeted biopsies when needed using the PrecisionPoint™ TP access device. Procedure-related complications and oncological outcomes were prospectively and consecutively collected. A validated questionnaire was used in a subset of centres to collect data on patient-reported outcome measures (PROMs). RESULTS: Some 1218 patients underwent LATP biopsies at 10 centres: 55%, 24%, and 21% for each of the three settings, respectively. Any grade PCa was diagnosed in 816 patients (67%), of which 634 (52% of total) had clinically significant disease. Two cases of sepsis were documented (0.16%) and urinary retention was observed in 19 patients (1.6%). PROMs were distributed to 419 patients, with a 56% response rate (n = 234). In these men, pain during the biopsy was described as either 'not at all' or 'a little' painful by 64% of patients. Haematuria was the most common reported symptom (77%). When exploring attitude to re-biopsy, 48% said it would be 'not a problem' and in contrast 8.1% would consider it a 'major problem'. Most of the patients (81%) described the biopsy as a 'minor or moderate procedure tolerable under local anaesthesia', while 5.6% perceived it as a 'major procedure that requires general anaesthesia'. CONCLUSION: Our data suggest that LATP biopsy using a TP access system mounted to the ultrasound probe achieves excellent PCa detection, with a very low sepsis rate, and is safe and well tolerated. We believe a randomised controlled trial comparing LATP with transrectal ultrasound-guided biopsy (TRUS) to investigate the relative trade-offs between each biopsy technique would be helpful.

Targeted and systematic cognitive freehand-guided transperineal biopsy: is there still a role for systematic biopsy?

OBJECTIVES: To assess whether targeted cognitive freehand-assisted transperineal biopsies using a PrecisionpointTM device still require additional systematic biopsies to avoid missing clinically significant prostate cancer, and to investigate the benefit of a quadrant-only biopsy approach to analyse whether a quadrant or extended target of the quadrant containing the target only would have been equivalent to systematic biopsy. PATIENTS AND METHODS: Patients underwent combined systematic mapping and targeted transperineal prostate biopsies at a single institution. Biopsies were performed using the Precisionpoint device (Perineologic, Cumberland, MD, USA) under either local anaesthetic (58%, 163/282), i.v. sedation (12%, 34/282) or general anaesthetic (30%, 85/282). A mean (range) of 24 (5-42) systematic and 4.2 (1-11) target cores were obtained. Magnetic resonance imaging (MRI) scans were reported using the Likert scale. Clinically significant cancer was defined as Gleason 7 or above. Histopathological results were correlated with the presence of an MRI abnormality within a spatial quadrant and the other adjoining or non-adjoining (opposite) quadrants. Histological concordance with radical prostatectomy specimens was analysed. RESULTS: A total of 282 patients were included in this study. Their mean (range) age was 66.8 (36-80) years, median (range) prostate-specific antigen level 7.4 (0.91-116) ng/mL and mean prostate volume 45.8 (13-150) mL. In this cohort, 82% of cases (230/282) were primary biopsies and 18% (52/282) were patients on surveillance. In all, 69% of biopsies (195/282) were identified to have clinically significant disease (Gleason ≥3 + 4). Any cancer (Gleason ≥3 + 3) was found in 84% (237/282) of patients. Of patients with clinically significant disease, the target biopsies alone picked up 88% (171/195), with systematic biopsy picking up the additional 12% (24/195) that the target biopsies missed. This altered with Likert score; 73% of Likert score 3 disease was detected by target biopsy, 92% of Likert score 4 and 100% of Likert score 5. Target biopsies with additional same-quadrant-only systematic cores picked up 75% (18/24) of significant cancer that was missed on target only, found in the same quadrant as the target. CONCLUSION: Systematic biopsy is still an important tool when evaluating all patients referred for prostate biopsy, but the need is decreased with increasing suspicion on MRI. Patients with very high suspicion of prostate cancer (Likert score 5) may not require systematic cores, unless representative surrounding biopsies are required for other specific treatments (e.g. focal therapy, or operative planning). More prospective studies are needed to evaluate this in full.

The impact of non-urothelial variant histology on oncological outcomes following radical cystectomy.

OBJECTIVES: To determine if the presence of non-urothelial variant histology (NUVH) is associated with a poorer prognosis following radical cystectomy (RC) compared to pure urothelial carcinoma (PUC). PATIENTS AND METHODS: A prospectively maintained database of all patients undergoing RC at a high-volume regional tertiary bladder cancer service between January 2010 and January 2017 was retrospectively analysed looking for patients with NUVH. Multivariate Cox proportional hazards regression analysis was used to determine disease recurrence, overall survival and bladder cancer-specific survival, as well as lymph node positivity. Association of tumour stage was determined using chi-squared analysis. RESULTS: In total, 430 patients underwent RC of which 73 (17%) had NUVH and 357 (83%) had PUC. The median (range) follow-up was 45.0 (8.5-100.2) months. The presence of NUVH was associated with both increased overall (hazard ratio [HR] 1.86, 95% confidence interval [CI] 1.21-2.85) and bladder cancer-specific mortality (HR 1.81, 95% CI 1.91-3.01), as well as disease recurrence (HR 1.71, 95% CI 1.06-2.75) in multivariate analysis. Squamous cell variant was also associated with increased overall mortality (HR 1.91, 95% CI 1.16-3.13), cancer-specific mortality (HR 2.03, 95% CI 1.21-3.42) and disease recurrence (HR 2.08, 95% CI 1.23-3.52), although this was not seen in other variant subtypes. Lymph node positivity was not associated with NUVH in multivariate analysis (HR 1.28, 95% CI 0.59-2.75), but NUVH was associated with advanced tumour stage on chi-squared analysis (P < 0.001). CONCLUSION: Our results showed a risk of shorter survival in NUVH compared to PUC. This suggests NUVH as an independent predictor of worse outcomes. As a result, patients with NUVH should be counselled preoperatively that overall and disease-specific outcomes are worse postoperatively and about the possible need for adjuvant treatment.

EXIT from TRansrectal prostate biopsies (TREXIT): sepsis rates of transrectal biopsy with rectal swab culture guided antimicrobials versus freehand transperineal biopsy.

BACKGROUND: Transrectal prostate biopsy (TRUSBx) holds a risk of prostate biopsy related sepsis. We discuss our step-wise strategies aiming to reduce this risk, including targeted antimicrobials and switching to a freehand transperineal approach (FHTPBx). SUBJECTS AND METHODS: This longitudinal cohort study included three groups. Group A underwent TRUSBx with empirical augmented antimicrobial prophylaxis; Group B underwent TRUSBx with targeted antimicrobial prophylaxis, based on rectal-swab cultures/sensitivity; Group C underwent FHTPBx with empirical antimicrobial prophylaxis. Post biopsy sepsis, defined according to the surviving sepsis campaign and confirmed with blood or urinary cultures, were determined and rates between groups were analysed using fisher's exact test. RESULTS: Of all 1501 patients, 23 developed post biopsy sepsis; Group A (12/609, 2.0%), B (9/403, 2.2%), C (2/489, 0.4%). Targeted antimicrobials did not reduce the risk of post biopsy sepsis following TRUSBx (A vs B, 2.0% vs 2.2%; p = 0.82). Patients with antimicrobial-resistant rectal flora had an increased post biopsy sepsis rate following TRUSBx despite targeted antimicrobials (9.1% vs 1.1%, p = 0.003). Switching to FHTPBx reduced the risk of developing post biopsy sepsis (A vs C, 2% vs 0.4%, p = 0.03; B vs C, 2.2% vs 0.4%, p = 0.03). CONCLUSIONS: Targeted antimicrobials based on rectal swab culture failed to reduce the overall risk of post biopsy sepsis, while FHTPBx nearly eliminated this risk. We recommend the use of transperineal prostate biopsies for all patients as the most effective method to reduce the risk of sepsis.

Safety of "hot" and "cold" site admissions within a high-volume urology department in the United Kingdom at the peak of the COVID-19 pandemic.

OBJECTIVES: To determine the safety of urological admissions and procedures during the height of the COVID-19 pandemic using "hot" and "cold" sites. The secondary objective is to determine risk factors of contracting COVID-19 within our cohort. PATIENTS AND METHODS: A retrospective cohort study of all consecutive patients admitted from March 1 to May 31, 2020 at a high-volume tertiary urology department in London, United Kingdom. Elective surgery was carried out at a "cold" site requiring a negative COVID-19 swab 72-hours prior to admission and patients were required to self-isolate for 14-days preoperatively, while all acute admissions were admitted to the "hot" site.Complications related to COVID-19 were presented as percentages. Risk factors for developing COVID-19 infection were determined using multivariate logistic regression analysis. RESULTS: A total of 611 patients, 451 (73.8%) male and 160 (26.2%) female, with a median age of 57 (interquartile range 44-70) were admitted under the urology team; 101 (16.5%) on the "cold" site and 510 (83.5%) on the "hot" site. Procedures were performed in 495 patients of which eight (1.6%) contracted COVID-19 postoperatively with one (0.2%) postoperative mortality due to COVID-19. Overall, COVID-19 was detected in 20 (3.3%) patients with two (0.3%) deaths. Length of stay was associated with contracting COVID-19 in our cohort (OR 1.25, 95% CI 1.13-1.39). CONCLUSIONS: Continuation of urological procedures using "hot" and "cold" sites throughout the COVID-19 pandemic was safe practice, although the risk of COVID-19 remained and is underlined by a postoperative mortality.

Predictors of Poor Response and Adverse Events Following Botulinum Toxin-A for Refractory Idiopathic Overactive Bladder.

OBJECTIVE: To ascertain whether a poor response and adverse events (voiding dysfunction and urinary tract infection) were predictable for first time botulinum toxin-A (BTX-A) injections in a patient cohort of refractory idiopathic overactive bladder with detrusor overactivity. METHODS: Patients who received BTX-A injections for the first time between the dates of March 2004-August 2017 were analyzed in this single center study. Urogenital Distress Inventory short form (UDI-6) questionnaires were collected both preinjection and postinjection prospectively. A poor response was defined as a decrease of less than 16.7 on the UDI-6 questionnaire. Additional information was gathered from patient records in a retrospective fashion. Predictors of poor response, voiding dysfunction, and UTI were analyzed with multivariate logistic regression analysis. RESULTS: Seventy-four patients were analyzed. The only predictor of poor response was male gender (OR, 5.45; 95% CI 1.83-16.47; P = .002). Lower maximum urinary flow rates (OR, 0.91; 95% CI, 0.83-0.99; P = .023), male gender (OR, 5.14; 95% CI 1.41-18.72; P = .013), and hysterectomy in females (OR, 4.55; 95% CI, 1.09-18.87; P = .038) were predictors of clean intermittent self catheterisation (CISC). There was an increased risk of UTIs in patients who performed CISC (OR, 5.26; 95% CI 1.38-20.0; P = .015). CONCLUSION: Male gender was associated with a poor response to BTX-A injections and increased risk of CISC. Lower maximum urinary flow rates and women with hysterectomies were at increased risk of requiring CISC postinjection. Performing CISC was associated with increased risk of UTI. These factors could be helpful when counselling or selecting patients.

Patient Perception and Emotional Disturbance in Out-of-Hour Ophthalmic Emergency Care.

PURPOSE: To investigate patient's perception of the severity of their symptoms, reasons for attending an ophthalmic emergency department (ED) out of hours, and to review the prevalence of anxiety and depression. METHODS: We carried out a prospective analysis of the cases presenting out of hours (8:30 PM to 8:30 AM) over a four-month period. We also conducted two questionnaire studies. First, patient's perception of the severity of their symptoms (graded from 1-10). A score of 7 or above was defined as significant. A second questionnaire study used the Hospital Anxiety and Depression Scale (HADS), with a maximum score of 21. Patients who scored between 7-10 points on either anxiety or depression scales are defined as borderline; above 10 as pathological. RESULTS: A total of 1,531 patients attended the out-of-hours service. The most common diagnoses were trauma (22.8%), infective conjunctivitis (10.2%), and contact-lens-related problems (6.6%). Of 175 completed questionnaires, worry about sight impairment and pain were the most common concerns for attendance. A total of 91% of patients believed their conditions were emergencies that require medical review within 24 hours. 127 HADS questionnaires were completed, showing that 18.9% and 15.0% of patients were suffering from borderline and pathological anxiety, respectively, with a mean HADS-A score of 6.5, SD=3.9. The prevalence of possible and pathological depression was 14.2% and 6.3%, mean=4.9 (SD=3.6). There was no statistical significance difference of score with the time of patient presentation. CONCLUSION: The prevalence of anxiety and depression is relatively high in patients who attended the ophthalmic ED and awareness of psychological impact should be raised amongst healthcare professionals.

Improving Compliance With a Single Post-Operative Dose of Intravesical Chemotherapy After Transurethral Resection of Bladder Tumour.

BACKGROUND: Post-operative single dose intravesical chemotherapy (PSDIVC) in patients with non-muscle invasive bladder cancer has been shown to reduce recurrence rates by up to 39%. However, some studies have suggested poor compliance with PSDIVC stating logistical issues and reluctance to give chemotherapy prior to histological confirmation as some of the reasons. OBJECTIVES: This study aims to analyse appropriate administration of PSDIVC practice in St. Mary's Hospital against European Association of Urology guidelines and implement an intervention bundle to improve practice. PATIENTS AND METHODS: All patients that underwent transurethral resection of bladder tumour (TURBT) between March 2012 and February 2013 were analysed retrospectively to review indication for post-operative chemotherapy, instillation rates and limiting factors preventing appropriate instillation. An intervention bundle including pre-operative delivery of mitomycin C (MMC) to the theatre suite, proforma placed in the operative notes and designated roles for PSDIVC induction was introduced to improve instillation and documentation rates. Prospective re-audit data was collected over six months between July 2013 and December 2013 following intervention. RESULTS: Sixty-four patients in group A underwent TURBT prior to introduction of the intervention bundle. Fifty-four patients had non-muscle invasive bladder cancer (NMIBC), which would have been eligible for PSDIVC. Fifteen (28% of NMIBC) were administered PSDIVC. Twenty-three (36% of all patients) were either given PSDIVC or had a documented contraindication. Thirty-one patients in group B underwent TURBT following induction of intervention bundle. Twelve (50% of NMIBC) patients were given PSDIVC. Twenty-eight (90% of all patients) were either given PSDIVC or had a documented contraindication. CONCLUSIONS: The intervention bundle prompted increased administration of PSDIVC and documentation. Similar centres may benefit from an intervention to improve compliance.

Upper ureteric transitional cell carcinoma, extending to the renal pelvis, presenting as duodenal obstruction.

A 61-year-old man presented with weight loss, dysphagia and vomiting. A barium swallow revealed a duodenal obstruction at D3. CT of the abdomen and pelvis showed a left upper ureteric tumour extending to the renal pelvis compressing the duodenum and causing left-sided hydronephrosis. Cystoscopy and left-sided ureteroscopy proved difficult and were unable to visualise or biopsy the mass, but a left ureteric stent was placed. Laparoscopic biopsy of the mass was completed and histology revealed transitional cell carcinoma. The patient went on to receive palliative chemotherapy, which relieved the small bowel obstruction, and the patient was able to eat solid food 8 weeks later. This case highlights a previously unreported cause of duodenal obstruction.

Escalation of care and failure to rescue: a multicenter, multiprofessional qualitative study.

BACKGROUND: The escalation of care process has not been explored in surgery, despite the role of communication failures in adverse events. This study aimed to develop a conceptual framework of the influences on escalation of care in surgery allowing solutions to facilitate management of sick patients to be developed. METHODS: A multicenter qualitative study was conducted in three hospitals in London, UK. A total of 41 participants were recruited, including 16 surgeons, 11 surgical PGY1s, six surgical nurses, four intensivists, and four critical care outreach team members. Participants were submitted to semistructured interviews that were analyzed using grounded theory methodology. RESULTS: A decision to escalate was based upon five key themes: patient, individual, team, environmental, and organizational factors. Most participants felt that supervision and escalation of care were problematic in their hospital, with unclear escalation protocols and poor availability of senior surgical staff the most common concerns. Mobile phones and direct conversation were identified to be more effective when escalating care than hospital pager systems. Transparent escalation protocols, increased senior clinician supervision, and communication skills training were highlighted as strategies to improve escalation of care. CONCLUSION: This is the first study to describe escalation of care in surgery, a key process for protecting the safety of deteriorating surgical patients. Factors affecting the decision to escalate are complex, involving clinical and professional aspects of care. An understanding of this process could pave the way for interventions to facilitate escalation in order to improve patient outcome.
