A phase 2 pilot study of water irrigation after transurethral resection of bladder tumor (WATIP) demonstrating safety, feasibility and activity.

PURPOSE: Non-muscle-invasive bladder cancer (NMIBC) can recur, partly due to seeding of free tumour cells after transurethral resection of bladder tumour (TURBT). Intravesical chemotherapy post-TURBT can reduce the risk but is used infrequently and inconsistently due to cost, complexity and side effects. The objective of this study was to prospectively assess continuous bladder irrigation using water, which may be a safer and easier alternative with comparable effectiveness. METHODS: WATIP was a prospective, single-arm phase 2 study of water irrigation during and for at least 3 h after TURBT for bladder tumours noted on imaging or flexible cystoscopy. Participants were assessed clinically for adverse effects and with blood tests within 24 h for sodium, haemoglobin and lactate dehydrogenase. The primary endpoints were safety (defined as < 10% adverse events of CTCAE grade ≥ 3), and feasibility (defined as the intervention being delivered as planned in > 90% of cases) and secondary endpoint was recurrence-free rates (RFR). RESULTS: Water irrigation was delivered as planned in 29 (97%) of 30 participants (median age 67 years, 25 (83%) males). The only adverse event (grade 2) was clot retention in one (3.3%) participant. Water irrigation significantly reduced urothelial cell counts in catheter effluent over time, unlike saline irrigation which did not. RFR was 56.2% (9/16 participants with low-risk NMIBC) at first cystoscopy (median interval 108 days) and 62.5% (5/8 evaluable low-risk NMIBC) at 12 months. CONCLUSION: Water irrigation during and after TURBT is feasible and safe. Prospective assessment of its effect on NMIBC recurrence compared to post-TURBT intravesical chemotherapy is needed before recommending its use in routine clinical practice.

Assessment of the axilla in women with early-stage breast cancer undergoing primary surgery: a review.

Sentinel node biopsy (SNB) is routinely performed in people with node-negative early breast cancer to assess the axilla. SNB has no proven therapeutic benefit. Nodal status information obtained from SNB helps in prognostication and can influence adjuvant systemic and locoregional treatment choices. However, the redundancy of the nodal status information is becoming increasingly apparent. The accuracy of radiological assessment of the axilla, combined with the strong influence of tumour biology on systemic and locoregional therapy requirements, has prompted many to consider alternative options for SNB. SNB contributes significantly to decreased quality of life in early breast cancer patients. Substantial improvements in workflow and cost could accrue by removing SNB from early breast cancer treatment. We review the current viewpoints and ideas for alternative options for assessing and managing a clinically negative axilla in patients with early breast cancer (EBC). Omitting SNB in selected cases or replacing SNB with a non-invasive predictive model appear to be viable options based on current literature.

Psychological Health of Surgeons in a Time of COVID-19: A Global Survey.

OBJECTIVE: To assess the degree of psychological impact among surgical providers during the COVID-19 pandemic. SUMMARY OF BACKGROUND DATA: The COVID-19 pandemic has extensively impacted global healthcare systems. We hypothesized that the degree of psychological impact would be higher for surgical providers deployed for COVID-19 work, certain surgical specialties, and for those who knew of someone diagnosed with, or who died, of COVID-19. METHODS: We conducted a global web-based survey to investigate the psychological impact of COVID-19. The primary outcomes were the depression anxiety stress scale-21 and Impact of Event Scale-Revised scores. RESULTS: A total of 4283 participants from 101 countries responded. 32.8%, 30.8%, 25.9%, and 24.0% screened positive for depression, anxiety, stress, and PTSD respectively. Respondents who knew someone who died of COVID-19 were more likely to screen positive for depression, anxiety, stress, and PTSD (OR 1.3, 1.6, 1.4, 1.7 respectively, all P < 0.05). Respondents who knew of someone diagnosed with COVID-19 were more likely to screen positive for depression, stress, and PTSD (OR 1.2, 1.2, and 1.3 respectively, all P < 0.05). Surgical specialties that operated in the head and neck region had higher psychological distress among its surgeons. Deployment for COVID- 19-related work was not associated with increased psychological distress. CONCLUSIONS: The COVID-19 pandemic may have a mental health legacy outlasting its course. The long-term impact of this ongoing traumatic event underscores the importance of longitudinal mental health care for healthcare personnel, with particular attention to those who know of someone diagnosed with, or who died of COVID-19.

'Pain-free TRUS B': a phase 3 double-blind placebo-controlled randomized trial of methoxyflurane with periprostatic local anaesthesia to reduce the discomfort of transrectal ultrasonography-guided prostate biopsy (ANZUP 1501).

OBJECTIVE: To determine whether the addition of inhaled methoxyflurane to periprostatic infiltration of local anaesthetic (PILA) during transrectal ultrasonography-guided prostate biopsies (TRUSBs) improved pain and other aspects of the experience. PATIENTS AND METHODS: We conducted a multicentre, placebo-controlled, double-blind, randomized phase 3 trial, involving 420 men undergoing their first TRUSB. The intervention was PILA plus a patient-controlled device containing either 3 mL methoxyflurane, or 3 mL 0.9% saline plus one drop of methoxyflurane to preserve blinding. The primary outcome was the pain score (0-10) reported by the participant after 15 min. Secondary outcomes included ratings of other aspects of the biopsy experience, willingness to undergo future biopsies, urologists' ratings, biopsy completion, and adverse events. RESULTS: The mean (SE) pain scores 15 min after TRUSB were 2.51 (0.22) in those assigned methoxyflurane vs 2.82 (0.22) for placebo (difference 0.31, 95% confidence interval [CI] -0.75 to 0.14; P = 0.18). Methoxyflurane was associated with better scores for discomfort (difference -0.48, 95% CI -0.92 to -0.03; P = 0.035, adjusted [adj.] P = 0.076), whole experience (difference -0.50, 95% CI -0.92 to -0.08; P = 0.021, adj. P = 0.053), and willingness to undergo repeat biopsies (odds ratio 1.67, 95% CI 1.12-2.49; P = 0.01) than placebo. Methoxyflurane resulted in higher scores for drowsiness (difference +1.64, 95% CI 1.21-2.07; P < 0.001, adj. P < 0.001) and dizziness (difference +1.78, 95% CI 1.31-2.24; P < 0.001, adj. P < 0.001) than placebo. There was no significant difference in the number of ≥ grade 3 adverse events. CONCLUSIONS: We found no evidence that methoxyflurane improved pain scores at 15 min, however, improvements were seen in patient-reported discomfort, overall experience, and willingness to undergo repeat biopsies.

Impact of radical prostatectomy on bladder function as demonstrated on urodynamics study-A systematic review.

AIMS: This study aims to describe the effects of radical prostatectomy (RP) on bladder function by performing a systematic review of urodynamics study findings before and after RP. METHODS: This systematic review was conducted in accordance with the PRISMA guideline and registered on PROSPERO (CRD42020206844). A systematic search was conducted using PubMed, Cochrane, and Embase. Studies were included if they involved men who underwent RP and had urodynamics study performed preoperatively, postoperatively, or both. Studies that included only subgroups of patients based on symptoms were excluded. Three hundred and four articles were screened, with 20 articles included. A qualitative analysis was performed. RESULTS: The rate of baseline bladder outlet obstruction (BOO) pre-RP was 19%-67%. All six studies with comparative data pre- and postoperatively demonstrated a decrease in the rate of patients with equivocal or clear obstruction. The baseline rates of detrusor overactivity (DO) varied widely from 11% to 61.2%. Six of eight studies with 6 months or more follow-up showed an improvement in the rates of DO ranging from 3.0% to 12.5%. The rate of de novo DO ranged from 0% to 54.5%. Four studies reported an increased rate of impaired bladder contractility and two of three studies showed a worsening rate of impaired bladder compliance following RP. This review is limited by the absence of level I/II studies. CONCLUSIONS: Urodynamics study shows that BOO is improved following RP in most patients. RP resolves DO in some patients and cause de novo DO in others. The net effect is a reduced overall rate of DO in most studies. Bladder compliance and contractility may be impaired after RP.

Patient-reported outcomes in non-muscle invasive bladder cancer: a mixed-methods systematic review.

OBJECTIVE: Non-muscle invasive bladder cancer (NMIBC) is a chronic condition requiring repeated treatment and endoscopic examinations that can occur life-long. In this context, patient-reported outcomes (PROs) are important considerations to patients and managing clinicians. We undertook a systematic review to synthesise PRO results relevant to NMIBC treatment to explore trajectories overtime and differences between treatment options. METHODS: We searched databases AMED, MEDLINE, EMbase, PsycINFO, Web of Knowledge and Scopus (inception to 5th December 2019), reference lists and contacted key authors to identify studies that reported PROs after NMIBC treatment. Two reviewers independently applied inclusion and quality criteria and extracted findings. Results for PROs were synthesised for treatment groups across three time periods: acute/during induction therapy; during maintenance therapy; and long-term follow-up (> 1 year). RESULTS: Of 3193 papers screened, 29 were eligible. These provided evidence about induction treatment effects, but few reported maintenance or long-term evidence, and evidence about differences between NMIBC treatment options was lacking. A range of symptoms (pain in bladder area, urinary frequency and urgency, pain or burning during urination) were commonly experienced during and soon after treatment for NMIBC. Less common symptoms included fatigue, disrupted sleep and gastrointestinal problems. CONCLUSIONS: Treatments for NMIBC can cause symptoms and functional impairment during the acute treatment phase and reduce quality of life. Clinicians should be aware of these impairments to prepare patients for short-term sequelae and enable those with treatment options to exercise preferences in choosing among them. However, gaps in current evidence limit our understanding of PRO trajectories from diagnosis through to long-term survivorship and treatment effects.

Identification of novel oncogenic events occurring early in prostate carcinogenesis using purified autologous malignant and non-malignant prostate epithelial cells.

OBJECTIVE: To interrogate enriched prostate cancer cells and autologous non-malignant prostate epithelial cells from men with localized prostate cancer, in order to identify early oncogenic pathways. PATIENTS AND METHODS: We collected malignant and matched non-malignant prostatectomy samples from men with adenocarcinoma involving two or more contiguous areas in only one lobe of the prostate. Tissue samples from both lobes were subjected to digestion and single-cell suspensions were prepared. Epithelial cell adhesion molecule-positive cells from cancerous and contralateral non-malignant (control) samples were isolated using magnetic beads, ensuring uniform populations were obtained for each donor. Unbiased RNA sequencing analysis was used to measure gene expression and for detection of transcribed mutations or splice variants that were over- or under-represented in malignant prostate epithelial cells relative to autologous control prostate epithelial cells. RESULTS: From five patient samples we identified 17 genes that were altered in prostate cancer epithelial cells, with 82% of genes being downregulated. Three genes, TDRD1, ANGTL4, and CLDN3, were consistently upregulated in malignant tissue. Malignant cells from three of the five patients showed evidence of upregulated ERG signalling, however, only one of these contained a TMPRSS2-ERG rearrangement. We did not identify mutations, gene rearrangements, or splice variants that were consistent amongst the patients. CONCLUSIONS: Events occurring early in prostate cancer oncogenesis in these samples were characterized by a predominant downregulation of gene expression along with upregulation of TDRD1, ANGTL4 and CLDN3. No consistent mutations or splice variants were observed, but upregulation of ERG signalling was seen both in the presence and absence of the classic TMPRSS2-ERG rearrangement.

Metformin may offer no protective effect in men undergoing external beam radiation therapy for prostate cancer.

OBJECTIVES: To assess whether metformin reduces radio-resistance and increases survival in men undergoing external beam radiation therapy (EBRT) for prostate cancer (PCa), and to determine its effect on hypoxia inducible factor 1-α (HIF1α). PATIENTS AND METHODS: All patients treated with curative intent with EBRT for PCa at a major cancer centre between 2000 and 2007 were included in this study. The outcome measures of time to biochemical failure (BF), metastasis, PCa-specific mortality and overall survival (OS) were analysed in those taking metformin vs those not, using competing risk and Cox regression models. To determine metformin's effect on HIF1α expression and survival in vitro, PC3 cells with high basal HIF1α levels were subjected to increasing doses of metformin after H2 O2 -induced oxidative stress. RESULTS: A total of 2055 eligible cases, including 113 who were on metformin, were identified, with a median follow-up of 95.7 months. There were no differences in age, initial prostate-specific antigen level, Gleason score, T-stage, D'Amico risk class or duration of androgen deprivation therapy (ADT) between patients who were or were not on metformin. Treatment with metformin did not result in any apparent improvement in time to BF, time to metastasis detection or OS, but there was a 1.5-fold increase in PCa-specific deaths (P = 0.045) in patients on metformin and ADT when adjusted for cancer risk and comorbidities. When comparing patients on high-dose metformin (>1 g/d) with those on low-dose metformin (≤1 g), there was no difference in either time to metastases or time to BF. In vitro metformin at a high concentration of 100 µM did not reduce HIF1α expression, nor did metformin affect the PC3 cell survival when exposed to oxidative stress (H2 O2 ). CONCLUSIONS: No association was found between the use of metformin and time to metastasis detection, time to BF or OS in patients undergoing radiation therapy with or without ADT for PCa. In vitro, low therapeutic concentrations of metformin had no effect on HIF1α, and this observation could explain the conflicting evidence for the effectiveness of metformin in men undergoing EBRT for PCa. Higher, more toxic doses of metformin may be required to inhibit the mammalian target of rapamycin-HIF1α pathway in this patient group.

Comparative sensitivity and specificity of imaging modalities in staging bladder cancer prior to radical cystectomy: a systematic review and meta-analysis.

PURPOSE: The detection of lymph node metastases in bladder cancer has a significant impact on treatment decisions. Multiple imaging modalities are available to clinicians including magnetic resonance imaging, computed tomography and positron emission tomography. We aimed to investigate the utility of alternate imaging modalities on pre-cystectomy imaging in bladder cancer for the detection of lymph node metastases. METHODS: We performed systematic search of Web of Science (including MEDLINE), EMBASE and Cochrane libraries in accordance with the PRISMA statement. Studies comparing lymph node imaging findings with final histopathology were included in our analysis. Sensitivity and specificity data were quantified using patient-based analysis. A true positive was defined as a node-positive patient on imaging and node positive on histopathology. Meta-analysis of studies was performed using a mixed-effects, hierarchical logistic regression model. RESULTS: Our systematic search identified 35 articles suitable for inclusion. MRI and PET have a higher sensitivity than CT while the specificity of all modalities was similar. The summary MRI sensitivity = 0.60 (95% CI 0.44-0.74) and specificity = 0.91 (95% CI 0.82-0.96). Summary PET/CT sensitivity = 0.56 (95% CI 0.49-0.63) and specificity = 0.92 (95% CI 0.86-0.95). Summary CT sensitivity = 0.40 (95% CI 0.33-0.49) and specificity = 0.92 (95% CI 0.86-0.95). CONCLUSION: MRI and PET/CT provides superior sensitivity compared to CT for detection of positive lymph nodes in bladder cancer prior to cystectomy. There is variability in the accuracy that current imaging modalities achieve across different studies. A number of other factors impact on detection accuracy and these must be considered.

Fiducial markers: can the urologist do better?

INTRODUCTION: Radiotherapy to the bladder has a risk of toxicity to pelvic structures, which can be reduced by using fiducial markers for targeting. Injectable contrast offers an alternative marker to gold seeds, which may fall out or exacerbate scarring. Combining contrast agents with tissue glue can minimize dispersion through tissue, enhancing its utility. We evaluated combinations of contrast agents and tissue glue using porcine bladder, for feasibility and utility as fiducial markers to aid image-guided radiotherapy. METHODS: Different contrast agents (Lipiodol ultra or Urografin) were combined with different tissue glues (Histoacryl, Tisseal or Glubran2). The mixtures were endoscopically injected into porcine bladder submucosa to identify the area of interest with multiple fiducial markers. The porcine bladders were imaged within a phantom porcine pelvis using standard radiation therapy imaging modalities. The feasibility as an injectable fiducial marker and visibility of each fiducial marker on imaging were scored as binary outcomes by two proceduralists and two radiation therapists, respectively. RESULTS: Lipiodol-glue combinations were successfully administered as multiple fiducials that were evident on CT and CBCT. Lipiodol with Histoacryl or Glubran2 was visible on kV imaging. The Lipiodol Glubran2 combination was deemed subjectively easiest to use at delivery, and a better fiducial on KV imaging. CONCLUSION: This study demonstrates the feasibility of mixing contrast medium Lipiodol with Histoacryl or Glubran2 tissue glue, which, injected endoscopically, provides discrete and visible fiducial markers to aid image-guided radiotherapy. Although promising, further study is required to assess the durability of these markers through a course of radiotherapy.

The use of hydrogel spacer in men undergoing high-dose prostate cancer radiotherapy: results of a prospective phase 2 clinical trial.

PURPOSE: The purpose of this study was to determine whether the degree of prostate to rectal separation using a hydrogel spacer (HS) and its effect on decreasing rectal dose can be reproduced in the community setting. METHODS: Thirty one patients with cT1-3aN0M0 prostate adenocarcinoma receiving radical radiotherapy to 78 Gy were recruited to the study. The primary endpoint was the proportion of patients achieving at least 25% reduction in volume of rectum receiving 70 Gy (rV70). Other endpoints included degree of prostate to rectum separation, HS insertion-related adverse events and the proportion of patients with grade 1 or worse acute or late gastrointestinal (GI) and genitourinary (GU) toxicity. RESULTS: All patients had successful insertion of their HS with no peri-operative toxicity. The mean prostate-rectal separation achieved was 10.5 mm. Twenty nine (93.5%) patients achieved a reduction in rV70 of at least 25%. Acute grade 1 GI toxicity was reported in 3 patients. All symptoms had resolved by 3 months post RT. Late grade 1 GI toxicity was reported in one patient (3.2%) with bowel frequency occurring at 6 months and resolving by 12 months post RT. There was no grade 2 or 3 acute or late GI toxicity seen. CONCLUSION: In conclusion, this study illustrates that the application and benefits of HS on reducing GI rectal dose endpoints and toxicities during prostate cancer RT can be reliably replicated in a community setting similar to centres participating in the randomised trial under high quality assurance trial monitoring.

Hierarchical task analysis for identification of interrelationships between ergonomic, external disruption, and internal disruption in complex laparoscopic procedures.

BACKGROUND: Traditionally, hierarchical task analysis (HTA) in surgery examines observable disruption in a predefined set of tasks as performed, rather than examining the ergonomics requirements, which may predispose surgical teams to act erroneously. This research aims to address this gap in the literature. It develops a HTA protocol taking into consideration surgical team actions, observable external disruption, internal disruption, and ergonomic goals required for safer conducting procedures. Laparoscopic radical prostatectomy (LRP) is selected as a case. METHODS: This research involved observations inside operating rooms (ORs) of three large teaching hospitals in Australia and China. Two rounds of observations are conducted: observations for developing HTA, and observations after presenting the developed HTA among surgical teams. The traditional HTA format is expanded to include two additional columns: technical considerations and ergonomics considerations. Two groups are formed from the observed LRPs. LRPs in the first group were conducted with no regard to the specified ergonomic goals and associated ergonomic features, and the second are conducted with the surgical teams attempting to follow specified ergonomic goals and features as prescribed in HTA. Careful attempt is required to select procedures such that the total operative times for both groups are approximately equal (± 5%). RESULTS: Between March 2016 and November 2017, a total of 29 LRPs were observed, and a HTA developed. The results reveal significant reduction (43%) in the total external disruptive events and approximately 58% reduction in the internal disruptive events in LRPs conducted with HTA requirements. CONCLUSIONS: The developed HTA appears to have some utility, but needs evaluation in larger studies. It can potentially be used as a training aid, and as a checklist for evaluating surgical performance.

Intraductal carcinoma of the prostate can evade androgen deprivation, with emergence of castrate-tolerant cells.

OBJECTIVE: To determine the relevance of intraductal carcinoma of the prostate (IDC-P) in advanced prostate cancer by first examining whether IDC-P was originally present in patients who later developed advanced prostate cancer and then using patient-derived xenografts (PDXs) to investigate the response of IDC-P to androgen deprivation therapy (ADT). MATERIALS AND METHODS: We conducted a retrospective pathology review of IDC-P in primary prostate biopsy or surgery specimens from 38 men who subsequently developed advanced prostate cancer. Overall survival was calculated using the Kaplan-Meier method. To demonstrate the response of IDC-P to ADT, we established PDXs from seven patients with familial and/or high-risk sporadic prostate cancer. After castration and testosterone restoration of host mice, we measured the volume and proliferation of IDC-P within PDX grafts. RESULTS: We found that IDC-P was a prominent feature in the primary prostate specimens, present in 63% of specimens and often co-existing with poorly differentiated adenocarcinoma. Overall survival was similar in patients with or without IDC-P. In the PDXs from all seven patients, IDC-P was identified and present at a similar volume to adenocarcinoma. Residual IDC-P lesions persisted after host castration and, similar to castrate-tolerant adenocarcinoma, testosterone restoration led to tumour regeneration. CONCLUSION: The study showed that IDC-P is prevalent in aggressive prostate cancer and contains cells that can withstand androgen deprivation. Thus, IDC-P appears functionally relevant in advanced prostate cancer. The presence of IDC-P may be a trigger to develop innovative clinical management plans.

Prospective analysis of hydrogel spacer for patients with prostate cancer undergoing radiotherapy.

OBJECTIVE: To report on the dosimetric benefits and late toxicity outcomes after injection of hydrogel spacer (HS) between the prostate and rectum for patients treated with prostate radiotherapy (RT). PATIENTS AND METHODS: In all, 76 patients with a clinical stage of T1-T3a prostate cancer underwent general anaesthesia for fiducial marker insertion plus injection of the HS into the perirectal space before intensity-modulated RT (IMRT) or volumetric-modulated arc RT (VMAT). HS safety, dosimetric benefits, and the immediate- to long-term effects of gastrointestinal (GI) toxicity were assessed. RESULTS: There were no postoperative complications reported. The mean (range) prostate size was 66.0 (25.0-187.0) mm. Rectal dose volume parameters were observed and the volume of rectum receiving 70 Gy (rV70 ), 75 Gy (rV75 ) and 78 Gy (rV78 ) was 7.8%, 3.6% and 0.4%, respectively. In all, 21% of patients (16/76) developed acute Grade 1 GI toxicities, but all were resolved completely by 3 months after treatment; whilst, 3% of patients (2/76) developed late Grade 1 GI toxicities. No patients had acute or late Grade ≥2 GI toxicities. CONCLUSION: Injection of HS resulted in a reduction of irradiated rectal dose volumes along with minimal GI toxicities, irrespective of prostate size.

Prospective randomised controlled trial of written supplement to verbal communication of results to patients at the time of flexible cystoscopy.

PURPOSE: This trial assessed if written information on procedural findings and subsequent treatment improved understanding and reduced anxiety among patients undergoing day case flexible cystoscopy (FC). METHODS: Participants completed pre- and post-procedure questionnaires self-rating anxiety and feeling well informed on 5-point Likert scales. Supplemental written information was provided after FC to half the patients on a standardized template, according to randomized allocation. Comparisons between the groups were undertaken using the Wilcoxon test. RESULTS: Two hundred patients were recruited, with 171 evaluable questionnaires (83 from written group). The distribution of age, sex and prior FC, as well as the pre-procedure self-assessment of anxiety and understanding, was similar between the two groups. Patients receiving written information reported feeling better informed, with median (range) Likert score of 5 (4-5) compared to 4 (1-5) out of 5 (p < 0.0001) and less anxious (score 1 [1-4] compared to 2 [1-5] out of 5, p < 0.005), although all except four patients had an accurate understanding of the information provided (p = NS). CONCLUSIONS: Written information at the time of FC leads to patients feeling better informed and less anxious, although verbal information alone appears to lead to an adequate understanding.

Factors affecting the timeliness and adequacy of haematuria assessment in bladder cancer: a systematic review.

OBJECTIVES: To review the literature to identify factors affecting haematuria assessment in bladder cancer. METHODS: We performed a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Publications indexed in EMBASE and Medline (PubMed) in March 2016 were searched, using the keywords 'hematuria', 'urinary bladder neoplasm(s)' and 'bladder tumor'. Studies evaluating the timeliness and adequacy of haematuria assessment in the context of bladder cancer were included. Exclusion criteria included age <18 years, animal studies and non-English articles. RESULTS: Following our search strategy, a total of 17 articles were included in our study. All 17 studies commented on gender, with female gender associated with delayed and inadequate haematuria evaluation. Women waited longer than men for urological review (three studies) and bladder cancer diagnosis (three studies). Women were also less likely to be referred to urology (two studies), receive imaging (three studies) or have cystoscopy (two studies). In all, 10 studies commented on age, with the impression that advancing age is associated with a more thorough assessment. Smokers and those with microscopic haematuria appear to undergo a less thorough evaluation. CONCLUSION: Female gender is associated with sub-optimal haematuria evaluation, while older patients are evaluated more thoroughly. Smokers paradoxically undergo less comprehensive assessment. Further research on the impact of other factors is required.

Predictors of delay to cystoscopy and adequacy of investigations in patients with haematuria.

OBJECTIVE: To identify factors that impact on the timeliness and adequacy of haematuria evaluation. PATIENTS AND METHODS: We undertook a retrospective cohort study identifying patients who underwent cystoscopy for investigation of haematuria at our institution between 1 January 2015 and 31 December 2015. Data on patient demographics, smoking status, anticoagulation, type of haematuria and referring clinician were collected. Exclusion criteria included patient age <18 years, known history of bladder/urinary tract/renal cancer, cystoscopy for indications other than haematuria and unknown date of urology consultation. Primary outcome measures were: i) time from general practitioner (GP) referral to urology consultation, ii) time from urology consultation to cystoscopy, and iii) receipt of investigations in the 180 days prior to cystoscopy. Comparisons between risk factors were carried out using negative binomial regression for count outcomes and chi-square test for categorical outcomes. RESULTS: Over the study period, 305 eligible cases (225 men, 80 women) were identified, of which 196 (64%) were referred by a GP. Patients waited a median of 38 days from GP referral to urology consultation and 28 days from urology consultation to cystoscopy. The median time to urology consultation was 65 days for women and 33.5 days for men (P = 0.020). However, the observed difference between men and women was no longer statistically significant on multivariable regression, with the only independent predictors of a shorter interval being visible haematuria and imaging suspicious for cancer. Anticoagulated patients were more likely to have imaging studies, in particular renal tract ultrasonography (P = 0.006), while only 61% of patients with visible haematuria received imaging. No significant differences in recent investigations between genders were observed. CONCLUSIONS: Gender is not a significant predictor of delayed haematuria assessment or receipt of recent investigations. Anticoagulated patients are more likely to receive imaging than patients without anticoagulation and patients with visible haematuria are not adequately imaged. Improved clinician and public education is required to ensure that all patients are evaluated appropriately.

Implementation rates of uro-oncology multidisciplinary meeting decisions.

OBJECTIVES: To assess implementation rates of the consensus plans made at the uro-oncology multidisciplinary meeting (MDM) of an Australian tertiary centre, and analyse obstacles to implementation. METHODS: A retrospective review was performed of all patients discussed at the uro-oncology MDM at our institution between 1 January and 30 June 2015. Rates of referral for MDM discussion after a new histological diagnosis of malignancy, categorised by tumour type, were assessed. Patient records were interrogated to confirm MDM plan implementation, with the outcomes examined being completion of MDM plan within 3 months and factors preventing implementation. RESULTS: During the enrolment period, from 291 uro-oncological procedures, 240 yielded malignant histology of which 160 (67%) were discussed at the MDM. Overall, 202 patients, including 32 females, were discussed at the uro-oncology MDM. MDM consensus plans were implemented in 184 (91.1%) patients. Reasons for deviation from the MDM plan included delay in care, patient deterioration or comorbidities, patient preference, consultant decision, loss to follow-up, and change in patient scenario due to additional new information. CONCLUSION: The MDM is increasingly important in the care of uro-oncology patients, with about two-thirds of new diagnoses currently captured. There appear to be few barriers to the implementation of consensus plans, with nearly all patients undergoing the recommended management.
