Prostatic stromal tumour of uncertain malignant potential treated with robotic-assisted radical prostatectomy: medium-term oncological and functional outcome of two cases.

Stromal tumour of uncertain malignant potential (STUMP) is a rare tumour of the prostate with variable and unpredictable risk and clinical progression. There is no clear consensus on how it should be managed. We describe two cases of patients who presented to their general practitioners with raised prostate-specific antigen in one instance and an abnormal digital rectal examination in the other. Biopsies were carried out and a diagnosis of STUMP was made. Both cases were managed with robot-assisted radical prostatectomy and after 4.8 years of follow-up, there has not been any recurrence. This is the first reported UK case in which STUMP has been successfully managed with robotic surgery with excellent medium-term results. Radical prostatectomy can be used to treat STUMP tumour with good oncological and functional outcomes.

Incremental modification of robotic prostatectomy technique can lead to aggregated marginal gains to significantly improve functional outcomes without compromising oncological control.

INTRODUCTION AND OBJECTIVES: Surgeons should aim for continuous quality improvement. The aim of this study was to evaluate the impact of incremental changes to Robot Assisted Radical Prostatectomy (RARP) technique on intra-operative and early post-operative outcomes. PATIENTS AND METHODS: All cases of RARP performed by a single surgeon in a tertiary institution over a 2-year period were included in this evaluation. Routine clinical data were collected. Cases were retrospectively allocated to four groups depending on key technical steps (1 = standard anterior approach; 2 = anterior approach with preservation of endopelvic fascia, puboprostatic fascia and urachus; 3 = posterior approach for nerve spare, with preservation of endopelvic fascia, puboprostatic fascia and urachus; 4 = Retzius-sparing posterior approach). RESULTS: 187 patients were allocated to groups: 1 = 22, 2 = 53, 3 = 90, 4 = 22. There were no significant differences in pre-operative characteristics, except age: 1 = 62.5, 2 = 62, 3 = 62.5, 4 = 58.5 (p = 0.02). Intra-operative differences were found in console time: 1 = 195, 2 = 167, 3 = 195 4 = 136.5 min (p < 0.001); and proportion of non-nerve sparing cases: 1 = 36%, 2 = 17%, 3 = 13%, 4 = 0% (p = 0.044). No significant differences were found in lymph node dissections, blood loss or complications. Post-operatively, no differences were found in length of stay, pathological characteristics, margin status, lymph node yield, complications or PSA levels. Significant differences were seen in pad-free continence at 6 weeks: 1 = 23%, 2 = 23%, 3 = 34%, 4 = 73% (p < 0.01); and social continence (using 1 pad) at 6-weeks: 1 = 59%, 2 = 87%, 3 = 81%, 4 = 95% (p = 0.01). Significant differences in pad-free continence persisted at 12 months: 1 = 63%, 2 = 81%, 3 = 78%, 4 = 100% (p = 0.019). CONCLUSION: Our results suggest that aggregated marginal gains from incremental modification of RARP leads to significantly improved continence outcomes without compromising patient safety or oncological control.

Development and Validation of a Short Version of the Metric for the Observation of Decision-Making in Multidisciplinary Tumor Boards: MODe-Lite.

BACKGROUND: Evidence-based tools are necessary for scientifically improving the way MTBs work. Such tools are available but can be difficult to use. This study aimed to develop a robust observational assessment tool for use on cancer multidisciplinary tumor boards (MTBs) by health care professionals in everyday practice. METHODS: A retrospective cross-sectional observational study was conducted in the United Kingdom from September 2015 to July 2016. Three tumor boards from three teaching hospitals were recruited, with 44 members overall. Six weekly meetings involving 146 consecutive cases were video-recorded and scored using the validated MODe tool. Data were subjected to reliability and validity analysis in the current study to develop a shorter version of the MODe. RESULTS: Phase 1, a reduction of the original items in the MODe, was achieved through two focus group meetings with expert assessors based on previous research. The 12 original items were reduced to 6 domains, receiving full agreement by the assessors. In phase 2, the six domains were subjected to item reliability, convergent validation, and internal consistency testing against the MODe-Lite global score, the MODe global score, and the items of the MODe. Significant positive correlations were evident across all domains (p < 0.01), indicating good reliability and validity. In phase 3, feasibility and high inter-assessor reliability were achieved by two clinical assessors. Six domains measuring clinical input, holistic input, clinical collaboration, pathology, radiology, and management plan were integrated into MODe-Lite. CONCLUSIONS: As an evidence-based tool for health care professionals in everyday practice, MODe-Lite gives cancer MTBs insight into the way they work and facilitates improvements in practice.

Orthotopic bladder substitution: Surgical aspects and optimization of outcomes.

Objectives: Orthotopic bladder substitution (OBS) is a management option for urinary diversion in men and women undergoing cystectomy. The aim of the procedure is to provide a functional continent urinary reservoir of adequate capacity, compliance and low pressure. We have provided a narrative review of the existing literature and highlighted areas where improvement and standardization can be recommended. Methods: Literature search included database search for publications from January 1970 to November 2020, using keywords including OBS, bladder reconstruction, neobladder, radical cystectomy, robotic cystectomy, intracorporeal neobladder, surgical technique, patient selection and outcomes. Results: Due to various factors including indications, operative technique and risk of complications, OBS is an enormous undertaking and commitment for patients, surgeons and health professionals involved in the care pathway. The main considerations for patient selection, the technical elements of the procedure and the rationale behind these are discussed. Previously considered to be a choice for a select few, the inclusion criteria have expanded over the last decade. Similarly, surgical techniques including the choice and configuration of bowel segments, construction of anastomosis and nerve or organ sparing procedures have evolved over the years. Minimally invasive laparoscopic and robotic assisted surgery has added further perspectives to the existing literature on OBS. Understanding the principles of operative techniques and assessing the best evidence to influence patient management is crucial as it has a major impact on clinical outcomes. Peri- and post-operative care, focused on the prevention of complications and morbidity, affects long-term functional and oncological outcomes, which ultimately dictates the quality of life. Conclusions: This concise overview of OBS literature highlights the importance of pre-operative, peri-operative, and post-operative aspects with regards to the optimization of patient care. To achieve the best results, meticulous attention should be paid in all these areas, surgical and multi-disciplinary. Patient education and counseling, with shared decision making are central to the success of the procedure.

Aggressive Angiomyxoma of the Bladder Neck Requiring Local Excision and Mitrofanoff Formation.

Aggressive angiomyxoma is a rare mesenchymal tumour predominantly affecting the female pelvis and perineum but has also been described in males. This tumour can often present a diagnostic challenge and has a propensity for local recurrence after surgical excision. We present an unusual case of aggressive angiomyxoma arising from the bladder of a female patient which required local excision and Mitrofanoff formation.

Stem cell therapy for stress urinary incontinence: a systematic review in human subjects.

PURPOSE: To systematically evaluate the current evidence on the safety and efficacy of stem cell therapy (SCT) in stress urinary incontinence (SUI) to allow objective comparison with existing surgical techniques. METHODS: Systematic literature search of Medline from years 1946-2012 using terms: "stem", "cell", "stress", "urinary", and "incontinence". Included studies presented empirical data on the treatment of SUI using SCT. OUTCOMES: adverse events, incontinence, quality of life, urodynamic, transurethral ultrasound and urethral EMG findings. RESULTS: Eight studies met inclusion criteria (seven observational and one randomized). Quality score: median 10.75 of 20 (range 2-12.5). Adverse events: one patient had bladder perforation and two procedures could not be completed due to pain. Temporary urinary retention and cystitis were also reported. Incontinence score: Four studies describe significant improvement. Quality of life: significant improvement in four studies. Urodynamic outcomes: four studies show significant improvement in contractility of urethral sphincter; three studies demonstrate no change in bladder capacity and significant reduction in residual volume; significant improvement in urinary flow three studies, although two found no difference; increase in leak point pressure and detrusor pressure in three studies. Urethral ultrasound: three studies found significant increases in rhabdosphincter thickness and contractility. Urethral EMG: two studies found significant increases in the EMG at rest and at contraction. CONCLUSION: Data suggest that SC treatment for SUI is safe and effective in the short term. However, the quality and maturity of the data are limited. Robust data from better quality studies comparing this to current surgical techniques are needed.

Multidisciplinary cancer team meeting structure and treatment decisions: a prospective correlational study.

BACKGROUND: Anecdotally, organizational factors appear to have an effect on the quality of decision-making in the multidisciplinary team (MDT) meeting. We assess the effect of the number of team-members present, number and order of cases, and the timing of meetings on the process of decision-making in MDT meetings. METHODS: Between December 2009 and January 2010, data were prospectively collected on treatment decisions, meeting characteristics, quality of information, and teamworking for all cases discussed at a London-based MDT meeting. Variables measured using a validated assessment tool (MDT MODe) and correlational analyses were performed. RESULTS: Treatment decisions were reached in 254 of 298 (85%) cases. Cases toward the end of meetings were associated with lower rates of decision-making, information quality, and teamworking (r = -0.15 to -0.37). Increased number of cases per meeting and team members in attendance were associated with better information and teamworking (r = 0.29-0.43). More time per case was associated with improved teamworking (r = 0.16). A positive correlation was obtained between ability to reach decisions and improved information and teamworking (r = 0.36-0.54; all P ≤ 0.001). CONCLUSIONS: Organizational factors related to the structure of the MDT meeting are associated with variation in the likelihood of reaching a treatment decision. Further research is required to establish causation and to modify such factors in order to improve the quality of cancer care.

Facilitators and barriers to teamworking and patient centeredness in multidisciplinary cancer teams: findings of a national study.

BACKGROUND: Multidisciplinary teams (MDTs) are the standard means of making clinical decisions in surgical oncology. The aim of this study was to explore the views of MDT members regarding contribution to the MDT, representation of patients' views, and dealing with disagreements in MDT meetings-issues that affect clinical decision making, but have not previously been addressed. METHODS: Responses to open questions from a 2009 national survey of MDT members about effective MDT working in the United Kingdom were analyzed for content. Emergent themes were identified and tabulated, and verbatim quotes were extracted to validate and illustrate themes. RESULTS: Free-text responses from 1,636 MDT members were analyzed. Key themes were: (1) the importance of nontechnical skills, organizational support, and good relationships between team members for effective teamworking; (2) recording of disagreements (potentially sharing them with patients) and the importance of patient-centered information in relation to team decision making; (3) the central role of clinical nurse specialists as the patient's advocates, complementing the role of physicians in relation to patient centeredness. CONCLUSIONS: Developing team members' nontechnical skills and providing organizational support are necessary to help ensure that MDTs are delivering high-quality, patient-centered care. Recording dissent in decision making within the MDT is an important element, which should be defined further. The question of how best to represent the patient in MDT meetings also requires further exploration.

Multidisciplinary team working across different tumour types: analysis of a national survey.

BACKGROUND: Using data from a national survey, this study aimed to address whether the current model for multidisciplinary team (MDT) working is appropriate for all tumour types. PATIENTS AND METHODS: Responses to the 2009 National Cancer Action Team national survey were analysed by tumour type. Differences indicate lack of consensus between MDT members in different tumour types. RESULTS: One thousand one hundred and forty-one respondents from breast, gynaecological, colorectal, upper gastrointestinal, urological, head and neck, haematological and lung MDTs were included. One hundred and sixteen of 136 statements demonstrated consensus between respondents in different tumour types. There were no differences regarding the infrastructure for meetings and team governance. Significant consensus was seen for team characteristics, and respondents disagreed regarding certain aspects of meeting organisations and logistics, and patient-centred decision making. Haematology MDT members were outliers in relation to the clinical decision-making process, and lung MDT members disagreed with other tumour types regarding treating patients with advanced disease. CONCLUSIONS: This analysis reveals strong consensus between MDT members from different tumour types, while also identifying areas that require a more tailored approach, such as the clinical decision-making process, and preparation for and the organisation of MDT meetings. Policymakers should remain sensitive to the needs of health care teams working in individual tumour types.

Development and evaluation of a checklist to support decision making in cancer multidisciplinary team meetings: MDT-QuIC.

BACKGROUND: The quality of decision-making in cancer multidisciplinary team (MDT) meetings is variable, which can result in suboptimal clinical decision making. We developed MDT-QuIC, an evidence-based tool to support clinical decision making by MDTs, which was evaluated by key users. METHODS: Following a literature review, factors important for high-quality clinical decision making were listed and then converted into a preliminary checklist by clinical and safety experts. Attitudes of MDT members toward the tool were evaluated via an online survey, before adjustments were made giving rise to a final version: MDT-QuIC. RESULTS: The checklist was evaluated by 175 MDT members (surgeons = 38, oncologists = 40, specialist nurses = 62, and MDT coordinators = 35). Attitudes toward the checklist were generally positive (P < 0.001, 1-sample t test), although nurses were more positive than other groups regarding whether the checklist would improve their contribution in MDT meetings (P < 0.001, Mann-Whitney U test). Participants thought that the checklist could be used to prepare cases for MDT meetings, to structure and guide case discussions, or as a record of MDT discussion. Regarding who could use the checklist, 70% thought it should be used by the MDT chair, 54% by the MDT coordinator, and 38% thought all MDT members should use it. CONCLUSION: We have developed and validated an evidence-based tool to support the quality of MDT decision making. MDT members were positive about the checklist and felt it may help to structure discussion, improve inclusivity, and patient centeredness. Further research is needed to assess its effect on patient care and outcomes.

A painful perineal lump: an unusual case of ectopic breast tissue.

We report the case of a 40-year-old lady who presented with an episodically painful perineal lump. Clinical and radiological investigations were inconclusive. Excision biopsy confirmed an ectopic breast mass. Ectopic breast tissue is difficult to diagnose but close attention to clinical findings can help to guide further investigation and diagnosis.

Quality improvement in multidisciplinary cancer teams: an investigation of teamwork and clinical decision-making and cross-validation of assessments.

PURPOSE: Teamworking and clinical decision-making are important in multidisciplinary cancer teams (MDTs). Our objective is to assess the quality of information presentation and MDT members' contribution to decision-making via expert observation and self-report, aiming to cross-validate the two methods and assess the insight of MDT members into their own team performance. MATERIALS AND METHODS: Behaviors were scored using (i) a validated observational tool employing Likert scales with objective anchors, and (ii) a 29-question online self-report tool. Data were collected from observation of 164 cases in five MDTs, and 47 surveys from MDT members (response rate 70%). Presentation of information (case history, radiological, pathological, comorbidities, psychosocial, and patients' views) and quality of contribution to decision-making of MDT members (surgeons, oncologists, radiologists, pathologists, nurses, and MDT coordinators) were analyzed via descriptive statistics and the Jonckheere-Terpstra test. Correlation between observational and self-report assessments was assessed with Spearman's correlations. RESULTS: Quality of information presentation: Case histories and radiology information rated highest; patients' views and comorbidities/psychosocial issues rated lowest (observed: Z = 14.80, P ≤ 0.001; self-report: Z = 3.70, P < 0.001). Contribution to decision-making: Surgeons and oncologists rated highest, nurses and MDT coordinators rated lowest, and others in between (observed: Z = 20.00, P ≤ 0.001; self-report: Z = 8.10, P < 0.001). Correlations between observational and self-report assessments: Median Spearman's rho = 0.74 (range = 0.66-0.91; P < 0.05). CONCLUSIONS: The quality of teamworking and clinical decision-making in MDTs can reliably be assessed using observational and self-report metrics. MDT members have good insight into their own team performance. Such robust assessment methods could provide the basis of a toolkit for MDT team evaluation and improvement.
