BackgroundMyeloid sarcoma is a rare extramedullary tumour of immature granulocytes, most commonly involving the skin, bone, lymph nodes, and soft tissue. It is usually associated with a diagnosis of relapsed or de novo acute myeloid leukaemia, acute lymphoblastic transformation of a myelodysplastic/myeloproliferative neoplasm, or can occur as isolated myeloid sarcoma.Case reportA 66-year-old female with a 7-year history of stable chronic myelomonocytic leukaemia presents with urgency, frequency, dysuria symptoms, and without new constitutional symptoms. She is found to have atypical, multifocal lesions on the right posterolateral wall of the bladder with associated hydronephrosis. Pathology reveals the diagnosis as myeloid sarcoma; surprisingly, bone marrow evaluation does not show evidence of acute leukaemic transformation.ConclusionsMyeloid sarcoma occurring in patients with chronic myelomonocytic leukaemia is extremely rare, and there are no cases reported in the English literature of these patients developing lesions in the bladder. The urological manifestations of an underlying haematological malignancy are best managed with a combination of systemic chemotherapy and allogeneic stem cell transplant, and in this case, the only surgical intervention required was ureteric stenting and tissue biopsy. Although rare, it is essential to consider alternative diagnoses when confronted with an atypical bladder tumour; failure to do so may result in patient harm by exposure to unnecessary intervention and delay to potentially curative treatment.

Background: A 76-year-old male presenting with macroscopic haematuria was found to have a lobulated mass infiltrating along the urothelium at the site of insertion of the upper moiety of a complete duplex right kidney. Suspected of being upper tract urothelial carcinoma, cystoscopy, bilateral retrograde pyelograms and transurethral resection of bladder tumour were attempted. Intra-operative findings revealed no tumour burden in the bladder or left ureter. The insertion of the upper pole moiety of the right ureter was not identified intra-operatively. Pelvic MRI demonstrated a markedly dilated upper pole moiety of the right ureter with a soft tissue mass in its distal aspect. Interestingly, the distal portion of the ectopic upper pole moiety was found to insert into the bladder neck. Objective and Methods: We report on an unusual case of upper tract urothelial carcinoma arising from the upper moiety of a complete duplex kidney. Our aim was to demonstrate the importance of thorough investigation of suspected urothelial carcinomas occurring in association with variant upper tract anatomy. Results and Conclusion: This case demonstrates the importance of thorough radiological and endourological investigation of suspected upper tract urothelial carcinoma and the various congenital abnormalities that may complicate the surgical management of this common malignancy. Level of evidence: 4 (case report)

Introduction: Our experience with the presence of detrusor muscle (DM) following Trans-Urethral Resection of Bladder Tumour (TURBT). Objectives: To evaluate the presence of DM in primary TURBT specimens as a quality improvement exercise in Frimley Park Hospital, UK. And to assess if the level of the surgeon has impact on outcomes. Methods: Retrospective and prospective analysis of the electronic records from a single urology centre, servicing a group of urologists. Data collected over three consecutive audit loops between January 2014 and May 2018. Results: A total of 301 cases were performed under the care of seven consultant urologists. Analysis revealed a significant improvement in the overall quality of resections from 39% to 66% (50–84% for intermediate and high grade) after the introduction of the following interventions: (1) analysis and improved awareness of current practice; (2) introduction of European Association of Urology (EAU) guidelines by separating samples and sending a second specimen pot marked as bladder tumour base to look for DM; (3) dedicated urologists with an interest in bladder cancer performing en-bloc resection technique in appropriate cases. Conclusion: Through our closed-loop audits, we have demonstrated a considerable improvement in the quality of resections, resulting in accurate staging from the initial resection. This could in turn lead to improved over all prognoses and negating the need for re-resection in all cases of high-risk non-muscle invasive bladder cancer (NMIBC). Level of evidence: 3

Abstract Background To compare 5-aminolevulinic acid (5-ALA)-mediated photodynamic diagnosis (PDD) with narrow-band imaging (NBI) for cancer detection during transurethral resection of bladder tumour (TURBT). Methods Between June 2018 and October 2020, 114 patients and 282 lesions were included in the analysis. Patients were orally administered 5-ALA (20 mg/kg) 2 h before TURBT. The bladder was inspected with white light (WL), PDD, and NBI for each patient, and all areas positive by at least one method were resected or biopsied. The imaging data were then compared to the pathology results. Results The sensitivities of WL, PDD, and NBI for detecting urothelial carcinoma were 88.1%, 89.6%, and 76.2%, respectively. The specificity, positive predictive value, and negative predictive value for detecting urothelial carcinoma were 47.5%, 80.9%, and 61.3%, respectively, for WL; 22.5%, 74.5%, and 46.2%, respectively, for PDD; and 46.3%, 78.2%, and 43.5%, respectively, for NBI. PDD was significantly more sensitive than NBI for all lesions (p < 0.001) and carcinoma in situ (CIS) lesions (94.6% vs. 54.1%, p < 0.001). Conclusions PDD can increase the detection rate of bladder cancer, compared to NBI, by greater than 10%. Therefore, 100% of CIS lesions can be detected by adding PDD to WL.

Objective: Study was performed to determine content of arsenic in urinary bladder tumour tissue and association of BRCA1 and BRCA2 protein expression with urinary bladder carcinoma development. Materials and methods: This study was performed in a tertiary care hospital of Eastern India. Post-operative tumour tissue was analysed for arsenic content as well as BRCA1 and BRCA2 expression. Statistical analysis was done and association between stage, grade and BRCA1 and BRCA2 expression with arsenic level in tumour tissue was done. Results: Total 50 patients were included in study. Out of which 26 were arsenic positive as well as 24 were arsenic negative. Maximum patients in arsenic positive group were from arsenic endemic zones of West Bengal, India. There was significant correlation between higher stage and grade of tumour and arsenic positivity. BRCA1 correlation was significant with arsenic positive group whereas BRCA2 correlation was not significant with arsenic positive group. Conclusion: Bladder carcinomas are more common in arsenic endemic zones of our country. This association can help in future to develop drugs which act on selected mutation of genes such as BRCA1, especially in arsenic-associated bladder cancers.

BackgroundDespite National Institute for Clinical Excellence (NICE) guidelines suggesting the use of urine cytology (UC) for the diagnosis of bladder cancer, its use is variable. Reasons for this include sub-optimal sensitivity, financial cost, availability of alternative tests, and uncertainty over interpretation of results. Anecdotally, however, suspicious or malignant UC when other investigations are normal, occasionally leads to a cancer diagnosis. Therefore, we retrospectively assessed a cohort of our haematuria patients to determine the value of UC in cancer diagnosis and the clinical significance of atypical UC (graded as C3). Patients and methodsWe identified 3018 patients with haematuria referred on the suspected cancer pathway (“two-week wait”) in 2015. We retrospectively analysed clinical, demographic, and follow-up/outcome data in a random cohort of 500 cases. ResultsMedian follow up was 58 months. Urological malignancy was diagnosed in 61/500 patients; all were identified by cystoscopy or imaging, i.e., irrespective of UC result. No cases of atypical UC re-presented with a ‘missed’ cancer diagnosis within the five-year follow-up period. However, suspicious and malignant cytology was associated with high-grade/aggressive tumours and subsequent tumour recurrence. ConclusionUrine cytology did not identify any cancers that were not already found by imaging or cystoscopy. Atypical UC in the presence of negative haematuria investigations does not appear to be associated with malignancy, and therefore should not alter patient management nor prompt further investigation. Suspicious and malignant UC was associated with higher risk cancers and could therefore be used to prioritise waiting lists for transurethral resection of bladder tumour (TURBT), however, it is unclear whether this might benefit patient outcomes. We conclude therefore that UC has no role in haematuria investigations.

AimsA subset of patients with urothelial carcinoma (UCa) and lamina propria (LP) invasion in bladder biopsies/transurethral resections (TURs) are at significant risk for recurrence and have increased rates of progression to UCa with muscularis propria (MP) invasion. The clinicopathologic features of this patient population has not been well characterised in the Pathology literature.MethodsWe performed a search through our urologic pathology files and expert consult cases of the senior author for bladder biopsies/TURs of UCa with LP invasion and variant/divergent histology from 2014 to 2020. Patients with a prior diagnosis of UCa with MP invasion or upper tract UCa were excluded. Clinicopathologic data were obtained.ResultsNinety-five patients with at least one biopsy/TUR of UCa with LP invasion and variant/divergent histology were identified. Mean patient age was 72 years (range: 46–92 years) with a male predominance 2.3:1. Initial variant/divergent histologies identified were: glandular (35.8%), squamous (23.2%), micropapillary (20%), clear cell/lipid rich (12.6%), diffuse/signet ring/plasmacytoid (10.5%), nested (9.5%), sarcomatoid (6.3%), poorly differentiated/anaplastic (4.2%), small cell (2.1%), lymphoepithelioma-like (2.1%), osteoclast-like giant cells (1.1%) and tumour giant cells (1.1%). Two or more variant histologies were identified in 18.9% of these cases. The rate of micropapillary UCa was significantly higher in multifocal tumours compared with unifocal tumours (37% vs 7.1%).ConclusionsIn our cohort of patients undergoing early repeat biopsy/TUR, 75% of patients had persistent UCa. Additionally, almost 25% of patients had a prior diagnosis of UCa without a variant/divergent histology identified. Our findings highlight the critical role of repeat biopsy/TUR especially in a subset of patients who have variant/divergent histology, even in the absence of MP invasion.
