How well do we manage non-muscle invasive bladder tumors? A UK audit of real-life practices

Low-grade Urothelial Carcinoma Recurs at a Tempo that Naturally Accelerates Over Time

OBJECTIVE

To investigate the cadence of recurrence in patients with low grade intermediate-risk non-muscle invasive bladder cancer (LG IR-NMIBC) based on clinical determinants. We aim to describe patterns in rates of recurrence to better inform surveillance regimens for this chronic, burdensome, and costly disease.

METHODS

Using baseline and follow-up data from participants in the West Midlands' (United Kingdom, UK) Bladder Cancer Prognosis Programme (BCPP), we assessed overall recurrence rate and recurrence-free intervals throughout the follow-up period for IR-NMIBC participants. Recurrence-free intervals were calculated using the Kaplan-Meier method.

RESULTS

We identified 379 patients with G1/G2 pTa tumors classified as intermediate risk. Median age was 70 and 284/379 (75%) were male. The median follow-up time was 4.2 years (95% CI: 3.9-4.8). After 5 years of follow-up, 53% of patients had at least one recurrence. One-year recurrence-free survival (RFS) was 75% and 4-year RFS was 50%. The median time to or between 1st, 2nd, 3rd, 4th, and 5th sequential recurrences was 49, 19, 12, 14, and 10 months, respectively.

CONCLUSION

Over half of patients with IR-NMIBC are destined to recur. Our data suggest that a subset of patients experience acceleration of recurrence over time and that this acceleration may serve as a potential kinetic biomarker for these individuals that could inform surveillance intervals and future treatment strategies.

Non-muscle invasive urothelial bladder cancer in a 17-year-old male: A rare case report

INTRODUCTION AND IMPORTANCE

Urothelial carcinoma of the bladder predominantly affects adults with rare cases in young patients. This manuscript presents a rare case of urothelial carcinoma highlighting clinical characteristics, diagnosis, treatment, and prognosis in this age group. Our aim is to raise awareness among healthcare professionals for improved outcomes in children and adolescents with bladder urothelial carcinoma.

CASE PRESENTATION

A 17-year-old male presented with hematuria and urinary symptoms. No history of smoking, alcohol, surgeries, family conditions, or medications. The patient had environmental chemical exposure near an oil refinery. An initial ultrasound and Cystoscopy showed a sizable bladder tumor. A complete TURBT was done, followed by cauterization and catheter placement. The tumor was diagnosed as low-grade urothelial carcinoma (pT1). Follow-up cystoscopies after 3 and 9 months showed no recurrence.

CLINICAL DISCUSSION

Urothelial bladder carcinoma (UBC) is linked to occupational exposure and smoking. Limited research exists on UBC in young patients, but genetic factors and environmental exposure may play a role. In young individuals, UBC typically presents as low-grade, non-muscle invasive tumors (NMIBC). Transurethral resection may be sufficient for low-grade tumors, and postoperative follow-up with ultrasound is important. Larger tumors have a higher risk of recurrence and progression.

CONCLUSION

The present case emphasizes the need to consider urothelial bladder carcinoma as a potential cause of hematuria in young patients and conduct a thorough evaluation of all risk factors. Future research is needed to establish evidence-based guidelines for managing this condition in pediatric and adolescent patients.

Quality Indicators in the Clinical Specialty of Urology: A Systematic Review

CONTEXT

In health care, monitoring of quality indicators (QIs) in general urology remains underdeveloped in comparison to other clinical specialties.

OBJECTIVE

To identify, synthesise, and appraise QIs that monitor in-hospital care for urology patients.

EVIDENCE ACQUISITION

This systematic review included peer-reviewed articles identified via Embase, MEDLINE, Web of Science, CINAHL, Global Health, Google Scholar, and grey literature from 2000 to February 19, 2021. The review was carried out under the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) guidelines and used the Appraisal of Indicators through Research and Evaluation (AIRE) tool for quality assessment.

EVIDENCE SYNTHESIS

A total of 5111 articles and 62 government agencies were screened for QI sets. There were a total of 57 QI sets included for analysis. Most QIs focused on uro-oncology, with prostate, bladder, and testicular cancers the most represented. The most common QIs were surgical QIs in uro-oncology (positive surgical margin, surgical volume), whereas in non-oncology the QIs most frequently reported were for treatment and diagnosis. Out of 61 articles, only four scored a total of ≥50% on the AIRE tool across four domains. Aside from QIs developed in uro-oncology, general urological QIs are underdeveloped and of poor methodological quality and most lack testing for both content validity and reliability.

CONCLUSIONS

There is an urgent need for the development of methodologically robust QIs in the clinical specialty of general urology for patients to enable standardised quality of care monitoring and to improve patient outcomes.

PATIENT SUMMARY

We investigated a range of quality indicators (QIs) that provide health care professionals with feedback on the quality of their care for patients with general urological diseases. We found that aside from urological cancers, there is a lack of QIs for general urology. Hence, there is an urgent need for the development of robust and disease-specific QIs in general urology.

Concomitant Endoscopic Surgery for Bladder Tumors and Prostatic Obstruction: Are We Safely Hitting Two Birds with One Stone? A Systematic Review and Meta-Analysis

BACKGROUND

Lower urinary tract symptoms (LUTS) caused by benign prostatic obstruction (BPO) and bladder tumors may co-exist, especially among elderly patients. Transurethral resection of bladder tumors (TURBT) and endoscopic surgery for benign prostatic obstruction in the same setting are avoided by many surgeons due to concerns for tumor cell seeding and recurrences in the prostatic urethra.

AIM

The aim of this study was assess the effect of concomitant TURBT and endoscopic BPO surgery on oncological safety and patient quality of life via systematic review and meta-analysis.

METHODS

We searched the PubMed, Cochrane Library, EMBASE, Scopus, and Clinicaltrials.gov databases and sources of grey literature published before June 2021 for relevant studies. We performed a random-effects meta-analysis of odds ratios (ORs) or weighted mean differences (WMD) to compare concomitant TURBT and BPO surgery versus TURBT alone in terms of recurrence and progression rates. Accordingly, we undertook multiple subgroups and sensitivity analyses (PROSPERO: CRD42020173363).

RESULTS

Three randomized and twelve retrospective observational studies with 2421 participants were included. Across studies with good methodological quality, no statistically significant differences were demonstrated regarding overall bladder tumors recurrence rates between concomitant endoscopic BPO surgery and TURBT versus TURBT alone (OR: 0.81, 95% CI: 0.60-1.09, I² = 42%). Similarly, no significant differences were observed in recurrences located at the bladder neck and/or prostatic urethra (OR: 1.06, 95% CI: 0.76-1.47, I² = 0%), time to first recurrence (WMD: -0.2 months, 95% Cl: -2.2-1.8, I² = 48%), and progression rate (OR: 1.05, 95% CI: 0.67-1.64, I² = 0%). Subgroup analyses based on tumor grade, number of tumors, and utilization of single-instillation chemotherapy post-TURBT did not detect any significant differences in overall bladder tumor recurrence. The level of evidence was estimated as low for all outcomes. Concomitant surgery improved lower urinary tract symptoms.

CONCLUSION

Concomitant endoscopic BPO surgery and TURBT are oncologically safe and improve LUTS-related quality of life.

Transurethral resection of bladder tumour (TURBT) as a day-case: A real-world practice and patients’ perspective from a district general hospital (DGH)

Introduction:

Day-case transurethral resection of bladder tumour (TURBT) is currently only performed in 18% cases across the United Kingdom. To determine 30-day readmission rate and morbidity after day-case TURBT in a district general hospital (DGH) and to report patient demographics, quality of TURBT and early recurrence rate as well as patient feedback after day-case TURBT.

Methods:

A retrospective audit of day-case TURBTs over a 3-year pre-COVID19 (2017–20) was performed. We only included patients who underwent a TURBT and excluded any cystoscopy and biopsy or fulguration. A day-case TURBT pathway is in place in this centre. Feedback was obtained using hospital patient feedback forms.

Results:

We included 77 patients who underwent TURBT in the day-case theatre, of these 5 patients required in-patient stay after the surgery. Of the remaining 72 discharged on the same day, 8 were re-admitted (11%) for Clavien-Dindo I complications. The readmission/failed discharge group had a higher rate of older patients, with higher ASA scores and longer operative times, however resection quality and tumour characteristics were not different from the day-case TURBTs. All patients reported an overall positive experience (good or very good).

Conclusions:

In the first of its kind audit reporting patient feedback after day-case TURBT, the data obtained can provide us and other centres adopting day-case TURBTs guidance to employ better patient selection to reduce readmission rates. Hence, day-case TURBT can be a feasible option in appropriately selected patients, with a suitable pathway in place.

En bloc resection of bladder tumors: challenges and unmet needs in 2021

Non-muscle invasive bladder cancer accounts for the majority of new bladder cancer diagnoses, and endoscopic transurethral resection of bladder tumor (TURBT) represents the standard-of-care. Although a relatively safe and common procedure, TURBT is often hampered by the questionable quality of resection. The evolution of surgical techniques has brought en bloc resection of bladder tumor (ERBT) to the forefront. ERBT has emerged as an alternative to conventional TURBT, incorporating a more delicate en bloc sculpting and tumor excision, in contrast to 'piecemeal' resection by conventional TURBT. ERBT appears safe, feasible and effective with demonstrably higher rates of detrusor muscle in the pathologic specimen, all while providing better staging and obviating the need for a re-TURBT in selected patients. However, the method's adoption in the field is still limited. This review summarizes the recent evidence relevant to ERBT while further highlighting the technique's limitations and unmet needs.

Optimizing treatment for non muscle-invasive bladder cancer with an app

OBJECTIVES

To evaluate overall and recurrence-progression rate-adjusted concordance of treatment prescription in non-muscle-invasive bladder cancer (NMIBC) of an app based on the best available scientific evidence and the urologist's opinion.

METHODS

Development of an app (APPv) specifically designed for the treatment and follow-up of NMIBC and validation of the proposed APPv treatment endpoint by means of a prospective double-blind observational concordance study of related samples in 100 patients with initial or successive histological diagnosis of NMIBC.

RESULTS

The treatment prescribed by the urologist agrees with that proposed by the APPv in 64% of cases (kappa index 0.55, P < 0.0001). Regarding low risk, the agreement is 77% (kappa 0.55, P = 0.002), 63% (kappa 0.52, P < 0.0001) for intermediate risk, 17% (kappa 0.143, P = 0.014) in high risk and 66% (kappa 0.71, P = 0.01) for very high risk. Of patients receiving adjuvant intravesical treatment according to APPv, 89.1% remain free of recurrence vs. 61.1% of those with disagreement (P = 0.0004), with a RR 0.46 (95%CI: 0.25-0.86) vs. RR 2.4 (95%CI: 1.5-3.8, P = 0.001). In the APPv-urologist agreement group, 100% of patients are free of progression and 88.9% in the disagreement group (P = 0.004) with a RR 1 vs. RR 1.125 (95%CI: 1-1.26, P = 0.004).

CONCLUSIONS

APPv can improve adherence to treatment recommendations according to clinical practice guidelines and health outcomes at NMIBC.

En bloc resection, is this the future of non-muscle invasive bladder cancer management? Presentation of our technique and brief review of the literature

INTRODUCTION

The quality of the initial transurethral resection of bladder tumors (TURBT) plays a key role in accurate local staging thus affecting treatment decision-making and disease prognosis. TURBT is still the gold standard for non-muscle invasive bladder cancer (NMIBC). However, en bloc resection of bladder tumors (ERBT) gradually expanded as a promising alternative to TURBT, aiming to overcome certain inherent limitations of conventional resection. We hereby describe a step-by-step bipolar ERBT technique and briefly review the current trends surrounding the role of various en bloc techniques in the field.

CASE PRESENTATION

We present the case of a 65-year old patient undergoing bipolar ERBT for a single, approximately 2 cm, papillary bladder mass. An experienced urologist completed the procedure within 17 min and without any intra- or postoperative complications. No conversion to TURBT was needed, and an adequate specimen for histological assessment was obtained. The patient made an uneventful recovery, and no recurrence was noted at 12-months.

CONCLUSION

Our initial experience demonstrates that ERBT via bipolar current is relatively quick, safe, and reliable. Prospective comparative clinical trials will examine its efficacy, and long-term oncological superiority in managing NMIBC.

Clinicopathological patterns of bladder carcinoma over 1 year: experience from University Hospital of Nepal

PURPOSE

To define the clinical and pathological patterns of urinary bladder carcinoma from the University Hospital of Nepal.

METHODS

This is a retrospective analytical study. Patients with bladder mass who underwent surgery over 1 year and who had data record were included in the study. Demographic profile, type of surgery, findings on clinical examination, cystoscopy findings, histopathological report, tumor stage, and post-surgery adjuvant therapy were analyzed.

RESULTS

Out of 86 patients who underwent transurethral resection of bladder tumor, 77 patients had biopsy-proven malignant bladder tumor. Urothelial cancer was present in 96.1%. Male were 78.6%. The mean age of diagnosis was 65.5 ± 11.8 years. Non-muscle-invasive bladder cancer (NMIBC) was 3.7 times more common than muscle-invasive bladder cancer (MIBC). High-grade tumors (58.6%) were more common than low grade (41.4%). The detrusor muscle was present inthe biopsy specimen of 48 patients (64%). Re-TURBT within 2-6 weeks was considered based on histopathology reports for about half of the patients (45.3%). Upstaging and upgrading of the tumor was present in 5.8 and 5.8% of the patients, respectively. Residual tumor without upstaging and upgrading was present in 23.5%. One patient (1.3%) had Clavien-Dindo grade 1, three (4%) patients had grade 2 and two patients (2.7%) had grade 3b.

CONCLUSION

In the present study, patients with bladder cancer are younger than reported in other studies. Smokers are strongly predisposed. The histological pattern is similar to the Western and Asian populations. NMIBC and MIBC occur in proportion to that described as in other studies. We had a lower rate of recurrence, upstaging and upgrading. We had a lesser rate of acceptance for radical cystectomy in our patients.

Real World Outcomes of Patients with Bladder Cancer: Effectiveness Versus Efficacy of Modern Treatment Paradigms

Bladder cancer remains a common and insidious disease in the United States. There have been several advances in the understanding of the biology of bladder cancer, novel diagnostic tools, improvements in multidisciplinary care pathways, and new therapeutics for advanced disease over the past few decades. Clinical trials have demonstrated efficacy for new treatments in each disease state, but additional work is needed to advance the effectiveness of bladder cancer care. Real world data provide critical information regarding patterns of care, adverse events, and outcomes helping to bridge the efficacy versus effectiveness gap.
