Abstract
OBJECTIVE The utility of intraoperative frozen section analysis (FSA) at the surgical margins (SMs) in patients with upper urinary tract cancer has not been established. We herein assessed the clinical significance of routine FSA of ureteral SMs during nephroureterectomy (NU) or segmental ureterectomy (SU). MATERIALS AND METHODS A retrospective review of our Surgical Pathology database identified consecutive patients undergoing NU (n=246) or SU (n=42) for urothelial carcinoma from 2004 to 2018. FSA (n=54) was correlated with the diagnosis of frozen section controls, the status of final SMs, and the prognosis of patients. RESULTS During NU, FSA was performed in 19 (7.7%) patients and was significantly more often requested in cases with ureteral tumor (13.1%) than in those with renal pelvis/calyx tumor (3.5%). Final SMs at the distal ureter/bladder cuff were positive only in non-FSA cases in the entire NU cohort (8.4%; P=0.375) or those with tumor at the lower ureter (57.6%; P=0.046), but not in any of FSA patients (0%). During SU, FSA was performed in 35 (83.3%) cases, including 19 at either proximal or distal SM and 16 at both SMs (SU-FSA2). Final positive SMs were significantly more often detected in non-FSA patients (42.9%) than in all FSA (8.6%; P=0.048) or SU-FSA2 (0%; P=0.020) patients. Overall, FSAs were reported as positive or high-grade carcinoma (n=7), atypical or dysplasia (n=13), and negative (n=34), and all these diagnoses were confirmed accurate on the frozen section controls, except one with a revision from atypical to carcinoma in situ. Meanwhile, 16 (80.0%) of 20 cases with initial positive/atypical FSA achieved negative conversion by excision of additional tissue. Kaplan-Meier analysis revealed that SU-FSA did not significantly reduce the risk of tumor recurrence in the bladder, disease progression, or cancer-specific mortality. Nonetheless, NU-FSA was strongly associated with reduced progression-free (P=0.023) and cancer-specific (P=0.007) survival rates, compared with non-FSA, which may imply a selection bias (e.g., FSA for clinically more aggressive tumors). CONCLUSIONS Performing FSA during NU for lower ureteral tumor, as well as during SU, significantly reduced the risk of positive SMs. However, routine FSA for upper urinary tract cancer failed to considerably improve long-term oncologic outcome.

Abstract
Background: Our study aims to assess the feasibility and the reproducibility of fluorescent confocal microscopy (FCM) real-time assessment of urethral and ureteral margins during open radical cystectomy (ORC) for bladder cancer (BCa). Methods: From May 2020 to January 2022, 46 patients underwent ORC with intraoperative FCM evaluation. Each specimen was intraoperatively stained for histopathological analysis using FCM, analyzed as a frozen section (FSA), and sent for traditional H&E examination. Sensitivity, specificity, positive predictive value (PPV), and the negative predictive value (NPV) of FCM and FSA were assessed and compared with H&E for urethral and ureteral margins separately. Results: The agreement was evaluated through Cohen’s κ statistic. Urethral diagnostic agreement between FCM and FSA showed a κ = 0.776 (p < 0.001), while between FCM and H&E, the agreement was κ = 0.691 (p < 0.001). With regard to ureteral margins, an overall agreement of κ = 0.712 (p < 0.001) between FCM and FSA and of κ = 0.481 (p < 0.001) between FCM and H&E was found. Conclusions: FCM proved to be a safe, feasible, and reproducible method for the intraoperative assessment of urethral and ureteral margins during ORC. Compared to standard FSA, FCM showed adequate diagnostic performance in detecting urethral and ureteral malignant involvement.

Upper Tract Urinary Cancer Recurrence after Radical Cystectomy: Risk Assessment of Intraoperative Frozen Section. Urol Int 2022; 106:816-824. [DOI: 10.1159/000521804] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Accepted: 12/27/2021] [Indexed: 11/19/2022]
Abstract
<b><i>Introduction:</i></b> Upper tract urinary cancer recurrence (UTUCR) after radical cystectomy (RC) is outcome-limiting. Surgical recommendations on intraoperative performance of frozen section analysis (FSA) and management of positive ureteral margin (PUM) are lacking. <b><i>Methods:</i></b> 634 RC cases were identified (2010–2018). In patients with PUM, sequential ureteral resections up to a negative margin were performed. We investigated the accuracy of FSA, significance of PUM, and identified risk factors (RFs) to stratify patients for UTUCR. <b><i>Results:</i></b> FSA was performed in 355 patients, including a total of 693 ureters. FSA sensitivity was 0.93 and specificity 0.99. PUM conversion was possible in 52 (91.2%) cases. UTUCR occurred in 17 (4.8%) patients. Identified UTUCR RFs are non-muscle invasive bladder carcinoma (NMIBC) (OR 3.8, 95% confidence intervals [CI] 1.4–10.2, <i>p</i> = 0.008), multifocal bladder cancer in cystectomy specimen (OR 4.7, CI 1.1–20.8, <i>p</i> = 0.042), and recurrent NMIBC (OR 4.1, CI 1.5–10.9, <i>p</i> = 0.006). Risk-group stratification showed a six-fold increase in UTUCR risk (low-to high-risk). <b><i>Conclusion:</i></b> FSA is a sensitive and specific method to identify PUM. UTUCR occurs significantly more often in patients with recurrent, multifocal NMIBC at the time of RC. Patients can be risk stratified for UTUCR. In case of NMIBC-PUM, surgeons can safely opt for a kidney preserving strategy.

Accuracy of Frozen Section Analysis of Urethral and Ureteral Margins During Radical Cystectomy for Bladder Cancer: A Systematic Review and Diagnostic Meta-Analysis. Eur Urol Focus 2021; 8:752-760.

Abstract
CONTEXT The question of the ability of frozen section analysis (FSA) to accurately detect malignant pathology intraoperatively has been discussed for many decades. OBJECTIVE We aimed to conduct a systematic review and meta-analysis assessing the diagnostic estimates of FSA of the urethral and ureteral margins in patients treated with radical cystectomy (RC) for bladder cancer (BCa). EVIDENCE ACQUISITION The MEDLINE and EMBASE databases were searched in February 2021 for studies analyzing the association between FSA and the final urethral and ureteral margin status in patients treated with RC for BCa. The primary endpoint was the value of pathologic detection of urethral and ureteral malignant involvement with FSA during RC compared with the final margin status. We included studies that provided true positive, true negative, false positive, and false negative values for FSA, which allowed us to calculate the diagnostic estimates. EVIDENCE SYNTHESIS Fourteen studies, comprising 8208 patients, were included in the quantitative synthesis. Forest plots revealed that the pooled sensitivity and specificity for FSA of urethral margins during RC were 0.83 (95% confidence interval [CI] 0.38-0.97) and 0.95 (95% CI 0.91-0.97), respectively. While for the FSA of ureteral margins, the pooled sensitivity and specificity were 0.77 (95% CI 0.67-0.84) and 0.97 (95% CI 0.95-0.98), respectively. Calculated diagnostic odds ratios indicated high FSA effectiveness, and patients with a positive urethral or ureteral margin at final pathology are over 100 times more likely to have positive FSA than patients without margin involvement at final pathology. Area under the curves of 96.6% and 96.7% were reached for FSA detection of urethral and ureteral tumor involvement, respectively. CONCLUSIONS Intraoperative FSA demonstrated high diagnostic performance in detecting both urethral and ureteral malignant involvement at the time of RC for BCa. FSA of both urethral and ureteral margins during RC is accurate enough to be of great value in the routine management of BCa patients treated with RC. While its specificity was great to guide intraoperative decision-making, its sensitivity remains suboptimal yet. PATIENT SUMMARY We believe that the frozen section analysis of both urethral and ureteral margins during radical cystectomy should be considered more often in urologic practice, until quality of life-based cost-effectiveness studies can identify patients within each institution who are unlikely to benefit from it.

Abstract
OBJECTIVE Achieving negative status of distal ureteral margin at the time of radical cystectomy (RC), and its therapeutic benefit, remains controversial. The aim of this review was to evaluate frequency, reliability and impact of positive distal ureteral margin after radical cystectomy for bladder cancer on upper tract recurrence, cancer specific and overall survival, and to identify best candidates for intraoperative frozen section analyses. MATERIAL AND METHODS A systemic review was performed following the PRISMA guideline. PubMed/Medline (with following terms; bladder cancer or cystectomy and frozen section or ureteral margin), and Cochrane Library were searched up to April 2020, to identify all papers evaluating distal ureteral margin and discussing clinical interest. Previous reviews and single case reports were excluded. RESULTS In total, thirty-two relevant studies were identified. Mean rate of positive ureteral frozen section after RC was close to 10% [1.1-25.4%]. Frozen section (FS) achieved a very good specificity [83-100%] and reserved sensibility [45-100%]. In many cases, an initial positive margin on FS can be converted to negative. Positive FS and/or PS (permanent section) were associated with upper urinary tract recurrence (UUTR). Conversion from positive FS to negative PS was associated with low UUTR frequency and better cancer survival in large retrospective studies. The relevant prognostic factor associated with positive FS and/or PS was CIS within the bladder. CONCLUSION FS should be recommended for patients with CIS within the bladder. Achieving negative FS/PS might be associated with lower rates of UUTR and better survival, for patients with higher life expectancy. Prospective randomized controlled studies need to be performed to provide definitive recommendations in this area.

The impact of carcinoma in situ in ureteral margins during radical cystectomy: A case-controlled study. Urol Oncol 2021; 39:497.e1-497.e8. [PMID: 33579627 DOI: 10.1016/j.urolonc.2021.01.028] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Revised: 01/10/2021] [Accepted: 01/25/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND AND OBJECTIVE The presence of carcinoma in situ (Cis) in association with bladder cancer is associated with a poor prognosis. However, the prognosis associated with the presence of Cis in ureteral margins (CUM) during radical cystectomy has been poorly defined. To assess the prognosis associated with the presence of Cis in ureteral margins in patients with pM0 bladder cancer who have not undergone neoadjuvant chemotherapy. MATERIALS AND METHODS A retrospective case-control study was conducted between 2001 and 2016 using data from one academic center in France. From 1,450 radical cystectomies, 122 patients (case) who had CUM were matched according to age, sex, pTNM stage and urinary diversion method with a population sample of 122 patients (controls) who did not have Cis in ureteral margins during radical cystectomy. The survival analysis was performed by Kaplan-Meier using a (95%) CI. Multivariate Cox regression analysis was used to test the effect of CUM on cancer-specific survival. Recurrence-free survival was defined as a recurrence of urothelial carcinoma in the upper urinary tract. RESULTS AND LIMITATIONS The mean follow-up period was 55.43 ± 39.6 months. The rate of Cis in the bladder in the CUM cases group was evaluated at 11.47%. The median overall and specific survival was inferior in the CUM cases group estimated at 43.3 [35.33-56.93] months, 52.43 [42.16-68.93] months respectively compared to the control group with a significant difference (P= 0.001, P= 0.0039). The cumulative probability of urothelial recurrence-free survival was decreased in the case group compared with the control group (63.9% vs. 92.6%, P = 0.0001). Multivariate analysis shown that urothelial recurrence was associated with CUM [(P <0.001), (HR adjusted =11.31), (95% CI): (3.38-37.77)] and the macroscopic appearance of the ureter (thickened, dilated) [(P= 0.003), (HR adjusted =4.62), (95% CI): (3.31-8.84)]. CONCLUSION CUM is a poor prognostic factor that impacts cancer-specific survival and Recurrence-free survival. The presence of CUM has been independently associated with a significant increase in the risk of urothelial recurrence, and a decrease in both overall and specific survival. This supports the use of frozen section analysis to complete radical cystectomy without CUM.

Abstract
Objective To summarise the currently available literature and analyse available results of the outcome of intraoperative frozen-section analysis (FSA) on upper urinary tract recurrence (UUTR) after radical cystectomy (RC). Materials and methods A systematic review of the literature was performed according to the Cochrane Reviews guidelines and in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Articles discussing ureteric FSA with RC were identified. Results The literature search yielded 21 studies, on which the present analysis was done. The studies were published between 1997 and 2019. There were 10 010 patients with an age range between 51 and 95 years. Involvement of the ureteric margins was noted in 2–9% at RC. The sensitivity and specificity of FSA were ~75% and 99%, respectively. Adverse pathology on FSA and on permanent section, prostatic urothelial carcinoma involving the stroma but not prostatic duct, and ureteric involvement on permanent section were all more likely to develop UUTR. Neither evidence of ureteric involvement nor ureteric margin status on permanent section were significant predictors of overall survival. Conclusion Routine FSA is mandatory for a tumour-free uretero–enteric anastomosis and is predictive of UUTR. To lower the UUTR, FSA is not necessary if the ureters are resected at the level where they cross the common iliac vessels. FSA is indicated whenever the surgeon encounters findings suspicious of malignancy, e.g. ureteric obstruction, periureteric fibrosis, diffuse carcinoma in situ, induration or frank tumour infiltration of the distal ureter is discovered unexpectedly during surgery, and prostatic urethral involvement. Abbreviations CIS: carcinoma in situ; FSA: frozen-section analysis; HR: hazard ratio; PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analyses; RC: radical cystectomy; (UT)UC: (upper tract) urothelial carcinoma; UUT(R): upper urinary tract (recurrence)

Abstract
Introduction The objective of this study was to look at the usefulness and cost effectiveness of intraoperative frozen section analysis (FSA) of the ureters at the time of radical cystectomy. Methods Pathology notes of patients undergoing radical cystectomy for primary bladder cancer between the years 2000-2015 at our institution were reviewed. Results A total of 196 ureteric specimens from 98 patients were reviewed. Of the 98 patients, 9% (n = 9) had positive ureteric margins, of which all were ≥ T2, with 44% (4 of 9) being T = 4. In all cases of positive FSA, preoperative clinical staging was ≥ T2. In cases where cancer staging was upgraded post-cystectomy, there were no cases of positive FSA. After adjusting for tumor stage in ≥ T2a, using Cox regression analysis, positive frozen section was associated with a 4.2 fold increase in overall mortality (95%CI 1.3-13.8; p = 0.02). Cost associated with FSA was AU$1,351.90 to obtain 1 positive result. Conclusion Patients with positive ureteric FSA are at higher risk of mortality post cystectomy, despite excision to negative tissue. However, FSA of the distal ureters at cystectomy were unlikely to be positive unless the bladder cancer stage was ≥ T2. Hence, routine ureteric FSA may not be necessary in patients undergoing cystectomy for non-muscle invasive bladder tumors.

Miyamoto H. Clinical benefits of frozen section assessment during urological surgery: Does it contribute to improving surgical margin status and patient outcomes as previously thought? Int J Urol 2016; 24:25-31. [PMID: 27862367 DOI: 10.1111/iju.13247] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2016] [Accepted: 10/05/2016] [Indexed: 12/18/2022]
Abstract
Despite significant advances in patient selection as well as surgical technique over the past few decades, it is still not uncommon for patients with urological malignancy and positive surgical margins to be observed. Meanwhile, intraoperative pathology consultation with frozen section assessment, which generally provides useful information for the optimal procedure, has been widely utilized for the assessment of surgical margins during urological surgeries. Thus, it remains unanswered whether intraoperative frozen section assessment has an impact on final surgical margin status as well as long-term oncological outcomes. The present review summarizes and discusses available data assessing the utility of frozen section assessment of the surgical margins during urological surgeries, such as radical prostatectomy, partial nephrectomy and radical cystectomy. The current findings suggest that select patients might benefit from the routine frozen section assessment.

Abstract
CONTEXT Urothelial carcinoma is considered a pan-urothelial disease. As such, the remnant urothelium in the upper urinary tract and urethra following radical cystectomy (RC) remains at risk for secondary urothelial tumors (SUTs). OBJECTIVE To describe the incidence, diagnosis, treatment, and outcomes of patients with SUTs after RC. EVIDENCE ACQUISITION A systematic search was conducted using PubMed database according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines to identify studies between 1970 and 2016 reporting on malignant diseases of the urothelium after RC for bladder cancer. The search strategy separated between upper and lower tract urothelial tumors. EVIDENCE SYNTHESIS Of a total of 1069 studies, 57 were considered for evidence synthesis. SUTs occured in approximately 4-10% of patients after RC. Carcinoma in situ of the bladder, a history of nonmuscle invasive bladder cancer, and tumor involvement of the distal ureter are the strongest risk factors for secondary upper tract tumors. Risk factors for secondary urethral tumors represent urothelial malignancy in the prostatic urethra/prostate and bladder neck (in women), nonorthotopic diversions, and positive findings on permanent sections. The majority of patients (84%) with SUTs, presented with urothelial recurrence without evidence of metastasis. Of those, 84.0% were treated with surgery, 10.5% with systemic chemotherapy and/or radiotherapy, and 5.6% with topical chemotherapy and/or immunotherapy. After a median follow-up of 91 mo (range: 26-155), 65.9% of patients died of disease and 21.5% died of other causes. Detection and treatment of SUTs at an asymptomatic stage can reduce the risks of cancer-specfific and overall mortality by 30%. A limitation of the study is that the available data were retrospective. CONCLUSIONS SUTs are rare oncological events and most patients have an adverse prognosis despite absence of distant disease at diagnosis. Therefore, surveillance of the remnant urothelium should be implemented for patients with histological features of panurothelial disease as it may improve timely detection and treatment. PATIENT SUMMARY Secondary tumors of the renal pelvis, ureters, and urethra occur in approximately 4-10% of patients after radical removal of the bladder for bladder cancer. These patients' prognoses are reduced, likely due to delayed diagnosis. Therefore, routine surveillance might be important to detect tumors at an early stage.

Abstract
As even a mere thickening of the urothelium can harbor genetic changes identical to that of low grade papillary urothelial tumors, it is not always possible to clearly recognize a precursor lesion of urothelial carcinoma by routine histological diagnostics. Complementary immunohistochemical and molecular diagnostic methods assist the recognition of these entities. These methods especially help to identify clinically important genetically unstable cells as the hallmark of carcinoma in situ (CIS). Little is known about the clinical significance of the morphological subtypes of CIS, which range from large cell to micropapillary variants. For a better understanding of special types of bladder cancer (e.g. adenocarcinoma and squamous cell carcinoma), it seems to be important to define the phenotype and the molecular pattern of non-urothelial lesions, such as intestinal metaplasia and squamous metaplasia, better and more precisely.

Abstract
The first two authors contributed equally to this work Classification of upper tract urothelial preneoplastic and neoplastic lesions mirrors that of the urinary bladder, with all lesions of the bladder urothelium being possible in the upper tract and vice versa. There are three major groups of non-invasive urothelial neoplasms: flat, papillary, and inverted. These three groups share a similar morphological spectrum of intraurothelial changes, ranging from hyperplasia to dysplasia to carcinoma in situ. However, they differ in terms of architectural growth pattern compared to the surrounding non-neoplastic mucosal surface. Infiltrating urothelial carcinoma is defined as a urothelial tumor that invades beyond the basement membrane. Unlike in non-invasive papillary urothelial neoplasms (pTa), the role of histologic grade in pT1 and higher stage tumors has been suggested to be of only relative importance. The vast majority of tumors of the upper urinary tract are urothelial carcinoma. More commonly seen, however, are foci of squamous differentiation and, less frequently, glandular differentiation. Pure urothelial carcinomas also display a wide range of variant morphologies, and recognition of these morphologies is important for diagnosis, classification, and prognosis.
