Abstract
Urine cytology is a noninvasive, widely used diagnostic tool for screening and surveillance of genitourinary tract neoplasms. However, the absence of unified terminology and clear objective morphological criteria limits the clinical benefit of urine cytology. The Paris System for Reporting Urine Cytology (TPS) was developed with the goal of standardizing reporting and improving urine cytology performance in detecting high-grade malignancy (HGM). We aimed to evaluate potential effects of TPS on improving urine cytology diagnostic performance and clinical utility by conducting a systematic review and meta-analysis. We searched six electronic databases to identify cross-sectional and cohort studies written in English assessing the accuracy of urine cytology in detecting genitourinary tract malignancies of patients under surveillance or with clinical suspicion of malignancy from January 2004 to December 2022. We extracted relevant data from eligible studies to calculate relative distribution of cytology diagnostic categories; ratio of atypical to HGM cytology diagnosis; and risk of HGM (ROHGM) and HGM likelihood ratio (HGM-LR) associated with cytology diagnostic categories. We used a generalized linear mixed model with logit transformation to combine proportions and multilevel mixed-effect logistic regression to pool diagnostic accuracy measurements. We performed meta-regression to evaluate any significant difference between TPS and non-TPS cohorts. We included 64 studies for 99,796 combined total cytology samples, across 31 TPS and 49 non-TPS cohorts. Pooled relative distribution [95% confidence interval (CI)] of negative for high-grade urothelial carcinoma (NHGUC)/negative for malignancy (NM); atypical urothelial cells (AUC); suspicious for high-grade urothelial carcinoma (SHGUC)/suspicious for malignancy (SM); low-grade urothelial neoplasm (LGUN); and HGM categories among satisfactory cytology cases were 83.8% (80.3%-86.9%), 8.0% (6.0%-10.6%), 2.2% (1.4%-3.3%), 0.01% (0.0%-0.1%), and 4.2% (3.2%-5.5%) in TPS versus 80.8% (76.8-2.7%), 11.3% (8.6%-14.7%), 1.8% (1.2%-2.7%), 0.01% (0.0%-0.1%), and 3.3% (2.5%-4.3%) in non-TPS cohorts. Adopting TPS classification resulted in a significant increase in the frequency of NHGUC and a reduction in AUC cytology diagnoses, respectively. The AUC/HGM ratio in TPS cohort was 2.0, which showed a statistically significant difference from the atypical/HGM ratio of 4.1 in non-TPS cohort (p-value: 0.01). Moreover, the summary rate (95% CI) of LGUN called AUC on cytology significantly decreased to 20.8% (14.9%-28.3%) in the TPS compared with 34.1% (26.4%-42.8%) in non-TPS cohorts. The pooled ROHGM (95% CI) was 20.4% (6.2%-50.0%) in nondiagnostic (NDX), 15.5% (9.6%-24.2%) in NHGUC, 40.2% (30.9%-50.2%) in AUC, 80.8% (72.9%-86.8%) in SHGUC, 15.1% (5.7%-34.3%) in LGUN, and 91.4% (87.3%-94.3%) in HGM categories in TPS studies. NHGUC, AUC, SHGUC, and HGM categories were associated with HGM-LR (95% CI) of 0.2 (0.1-0.3), 0.9 (0.6-1.3), 6.9 (2.4-19.9), and 16.8 (8.3-33.8). Our results suggest that TPS 1.0 has reduced the relative frequency of AUC diagnosis, AUC/HGM ratio, and the frequency of LGUNs diagnosed as AUC on cytology. Adopting this classification has improved the clinical utility of SHGUC and HGM cytology diagnoses in ruling in high-grade lesions. However, an NHGUC diagnosis does not reliably rule out the presence of a high-grade lesion.

Kannan N, Gochhait D, Ramanitharan M, Siddaraju N. A comparison between conventional and the Paris systems of reporting urinary cytopathology with a literature update. Diagn Cytopathol 2024; 52:187-199.

Abstract
INTRODUCTION Owing to certain inherent limitations of earlier reporting systems, "The Paris System for Reporting Urinary Cytology (TPS)" was implemented in 2015 to standardize reporting urine cytology with more stringent cytomorphologic criteria. We share our post-TPS experience, comparing it with the conventional system (CS). AIM To assess and compare the cyto-histopathologic/cystoscopic agreement between the conventional and the Paris systems (CS and TPS) for reporting urine cytology. MATERIALS AND METHODS It is a cross-sectional study involving urine samples from 170 patients divided into two groups (CS and TPS). Of the 170 cases, 85 were reported according to the CS, and 85 were reported according to TPS with all the relevant clinical, radiologic, and cystoscopic findings. Using the kappa statistics, both groups were statistically analyzed for sensitivity, specificity, predictive values, and agreement. RESULTS The sensitivity and specificity for high-grade urothelial carcinoma (HGUC) as per TPS were 83.33% and 94.59%, respectively, while they were 73.47% and 80.56% for the conventional system. The agreement for HGUC with TPS was 87.06% with a kappa value of 0.7416, while it was 76.5% with a kappa value of 0.53 for the CS. Implementing the TPS minimized usage of the atypical urothelial cells (AUC) category, increasing the clarity in detecting HGUC. CONCLUSION TPS provides better agreement with histopathology than the CS for diagnosing HGUC, which is attributable to stringent TPS criteria that prompt cytopathologists to look more diligently for morphologic and numeric criteria.

Large-scale validation study of an improved semiautonomous urine cytology assessment tool: AutoParis-X. Cancer Cytopathol 2023; 131:637-654. [PMID: 37377320 PMCID: PMC11251731 DOI: 10.1002/cncy.22732] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 05/11/2023] [Accepted: 05/12/2023] [Indexed: 06/29/2023]
Abstract
BACKGROUND Adopting a computational approach for the assessment of urine cytology specimens has the potential to improve the efficiency, accuracy, and reliability of bladder cancer screening, which has heretofore relied on semisubjective manual assessment methods. As rigorous, quantitative criteria and guidelines have been introduced for improving screening practices (e.g., The Paris System for Reporting Urinary Cytology), algorithms to emulate semiautonomous diagnostic decision-making have lagged behind, in part because of the complex and nuanced nature of urine cytology reporting. METHODS In this study, the authors report on the development and large-scale validation of a deep-learning tool, AutoParis-X, which can facilitate rapid, semiautonomous examination of urine cytology specimens. RESULTS The results of this large-scale, retrospective validation study indicate that AutoParis-X can accurately determine urothelial cell atypia and aggregate a wide variety of cell-related and cluster-related information across a slide to yield an atypia burden score, which correlates closely with overall specimen atypia and is predictive of Paris system diagnostic categories. Importantly, this approach accounts for challenges associated with the assessment of overlapping cell cluster borders, which improve the ability to predict specimen atypia and accurately estimate the nuclear-to-cytoplasm ratio for cells in these clusters. CONCLUSIONS The authors developed a publicly available, open-source, interactive web application that features a simple, easy-to-use display for examining urine cytology whole-slide images and determining the level of atypia in specific cells, flagging the most abnormal cells for pathologist review. The accuracy of AutoParis-X (and other semiautomated digital pathology systems) indicates that these technologies are approaching clinical readiness and necessitates full evaluation of these algorithms in head-to-head clinical trials.

Iodinated Contrast Medium Affects Urine Cytology Assessment: A Prospective, Single-Blind Study and Its Impact on Urological Practice. Diagnostics (Basel) 2022; 12:diagnostics12102483. [PMID: 36292171 PMCID: PMC9600466 DOI: 10.3390/diagnostics12102483] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 10/05/2022] [Accepted: 10/12/2022] [Indexed: 11/30/2022] Open
Abstract
During endoscopic procedures for suspected urothelial tumors of the upper urinary tract, radiographic imaging using an iodinated contrast medium is often required. However, following ureteropyelography, we detected changes in cytology characteristics not correlating with real cytology findings in naive urine. The aim of our study was to assess cytology changes between naive and postcontrast urine according to The Paris System of cytology classification. Methods: We prospectively assessed urine samples from 89 patients (23 patients with histologically proven urothelial cancer and 66 healthy volunteers). The absence of malignancy was demonstrated by CT urography and/or ureteroscopy. The study was single blind (expert cytopathologist) and naïve Paris system for urine cytology assessment was used. Furthermore, additional cytological parameters were analyzed (e.g., specimen cellularity, degree of cytolysis, cytoplasm and nucleus color, chromatin and nucleo-cytoplasmic ratio). Results: Our study showed statistically significant differences when comparing naïve and postcontrast urine in healthy volunteers (only 51 % concordance, p = 0.001) versus malignant urine specimens (82 % concordance). The most important differences were in the shift from The Paris System category 2 (negative) to 1 (non-diagnostic) and from category 2 (negative) to 3 (atypia). Other significant changes were found in the assessment of specimen cellularity (p = 0.0003), degree of cytolysis (p = 0.001), cytoplasm color (p = 0.003), hyperchromasia (p = 0.001), course chromatin (p = 0.002), nucleo-cytoplasmatic ratio (p = 0.001) and nuclear borders’ irregularity (p = 0.01). Conclusion: Our unique study found crucial changes in the cytological assessment of naive and postcontrast urine and we confirm that postcontrast urine is more often assessed as abnormal, suspect or non-diagnostic. Therefore, before urine collection for cytology, the clinician should avoid administration of iodinated contrast into the urinary tract.

Abstract
Objectives:
The Paris System (TPS) for Reporting Urine Cytology has significantly improved the approach to evaluating urine cytology. TPS criteria were defined mainly according to ThinPrep and SurePath preparations, as they are widely utilized. The objective of this study is to validate urine cytology interpretation according to the TPS classification using cytospin technique in relation to the gold slandered histology.
Material and Methods:
This retrospective study examined and analyzed 316 urine specimens from King Abdulaziz University Hospital between 2015 and 2020. Cytospin technique is performed for all cases. Slides were recategorized using TPS criteria, then compared with the original histology diagnosis.
Results:
According to the TPS, 108 cases were classified as 101 AUC (32%), 95 NEG (30%), 59 HGUC (18.7%), 31 SHGUC (9.8%), and 30 (9.5%) others. The computed sensitivity of cytospin in urine cytology was 94.7%, with 73.9% specificity, a positive predictive value of 85.6%, a negative predictive value of 89.5%, and overall accuracy of 86.8%.
Conclusion:
Urine cytology testing is considered to be a non-invasive and sensitive method to screen for urothelial carcinoma. TPS defined standards are reliable on cytospin prepared slides for reporting urine cytology.

Abstract
Urothelial bladder cancer is a heterogeneous disease and one of the most common cancers worldwide. Bladder cancer ranges from low-grade tumors that recur and require long-term invasive surveillance to high-grade tumors with high mortality. After the initial contemporary treatment in non-muscle invasive bladder cancer, recurrence and progression rates remain high. Follow-up of these patients involves the use of cystoscopies, cytology, and imaging of the upper urinary tract in selected patients. However, in this context, both cystoscopy and cytology have limitations. In the follow-up of bladder cancer, the finding of urothelial cells with abnormal cytological characteristics is common. The main objective of our study was to evaluate the usefulness of a urine DNA methylation test in patients with urothelial bladder cancer under follow-up and a cytological finding of urothelial cell atypia. In addition, we analyzed the relationship between the urine DNA methylation test, urine cytology, and subsequent cystoscopy study. It was a prospective and descriptive cohort study conducted on patients presenting with non-muscle invasive urothelial carcinoma between 1 January 2018 and 31 May 2022. A voided urine sample and a DNA methylation test was extracted from each patient. A total of 70 patients, 58 male and 12 female, with a median age of 70.03 years were studied. High-grade urothelial carcinoma was the main histopathological diagnosis. Of the cytologies, 41.46% were cataloged as atypical urothelial cells. The DNA methylation test was positive in 17 urine samples, 51 were negative and 2 were invalid. We demonstrated the usefulness of a DNA methylation test in the follow-up of patients diagnosed with urothelial carcinoma. The methylation test also helps to diagnose urothelial cell atypia.

Abstract
The study of atypia in urinary cytology has been ongoing for decades but most studies have focused primarily on test performance in patients with concurrent biopsies and/or limited follow-up periods. While these data are useful, many studies fail to consider patient factors that may alter the pretest probability, which can subsequently affect test performance. An isolated diagnosis of malignancy in urinary cytology usually has a high positive predictive value and allows a urologist to conduct a rigorous workup of the patient to establish a tissue diagnosis. However, it is less certain how an atypical diagnosis impacts patient care, given that many patients have a history of bladder cancer and are already under surveillance with cystoscopy at regular screening intervals. Furthermore, a discrete negative urine cytology is unlikely to allow a patient to forego a cystoscopy procedure due to limitations in the sensitivity of urine cytology. Over the last several years, the introduction of The Paris System for Reporting Urinary Cytology (TPS) has improved the predictive value of atypical diagnoses, but additional studies are needed to evaluate the performance of these diagnoses in specific clinical situations. Such data could better inform urologists on how to manage patients with atypical diagnoses. This review discussed the diagnosis of atypia in urinary cytology and the impact of such a diagnosis in various clinical contexts.

Abstract
Introduction: Cells exfoliated into urine from the bladder can help to diagnose the cancer. The objective of this study was to validate the hypothesis that bladder cancer could be detected noninvasively by a simple and reliable assay targeting genomic VPAC (combined vasoactive intestinal peptide and pituitary adenylate cyclase-activating peptide family of cell surface receptors) receptors expressed on the malignant bladder cancer cells shed in the voided urine. Methods: Patients ≥18 years of age with either imaging (ultrasonography/computed tomography [CT])-confirmed bladder tumors or those who have been previously treated for nonmuscle invasive bladder tumors and were visiting the department for check cystoscopy, formed the study group. Freshly voided urine sample was collected from these patients and sent for conventional cytology examination, 5-aminolevulinic acid (ALA) fluorescent urine cytology, and for positivity of VPAC receptors. Results: A total of 103 patients were prospectively included in the study. Of these, 65 patients (Group I) presented with image-diagnosed (ultrasonography and/or CT) bladder cancer. The remaining 38 patients (Group II) were previously diagnosed cases of nonmuscle invasive bladder cancer and presented for follow-up and check cystoscopy. The sensitivity for VPAC receptor positivity was 89.23% compared to conventional cytology (63.07%) and 5-ALA fluorescent urine cytology (87.69%). The specificity of VPAC receptor positivity was 100% compared to conventional cytology (100%) and 5-ALA-induced fluorescent cytology (90.47%). Conclusions: Our preliminary study shows encouraging results with VPAC receptor positivity studies, which has a high sensitivity when compared to the conventional cytology.

Kuan KC, Segura SE, Ahlstedt J, Khader SN, Hakima L. The predictive value of positive and suspicious urine cytology: Are they different? Diagn Cytopathol 2020; 48:998-1002. [PMID: 32558388 DOI: 10.1002/dc.24531] [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: 05/12/2020] [Revised: 06/02/2020] [Accepted: 06/05/2020] [Indexed: 01/13/2023]
Abstract
BACKGROUND Urine cytology evaluation is an effective test in the detection of high-grade urothelial carcinoma (HGUC). While the guideline distinguishes the 2 categories: "positive for HGUC" (PHGUC) and "suspicious for HGUC" (SHGUC), the association between these categories with their subsequent follow-up biopsies remains unclear. This study aims to determine and compare the positive predictive value (PPV) of the specimens in PHGUC and SHGUC categories with their respective histologic diagnoses. METHODS During the period of 03/01/2008 to 07/31/2018, urine cytology cases diagnosed as PHGUC and SHGUC with subsequent bladder biopsy within 12 months were retrieved. All cases were correlated with first biopsy obtained during 12 months of cytology specimen. Biopsy result with HGUC, carcinoma in situ, or non-urothelial carcinoma diagnoses were considered as concordance. RESULTS 378 cases (229 SHGUC and 149 PHGUC) were identified from 263 patients. For the 229 SHGUC cases, the PPV was 72% (n = 166) and for the 149 PHGUC cases, the PPV was 85% (n = 127). While both categories have high PPV, they are statistically significant (p < 0.0001). Additionally, 33 cases were found to have low-grade urothelial carcinoma (LGUC), constituting a portion of discordant results. CONCLUSION PHGUC and SHGUC categories are both associated with a high risk of malignancy, however, there is a statistically significant difference between them in our study, supporting the PSRUC guidelines of two separate categories. In instances when urine cytology is discordant with biopsy results, further investigation and clinical follow up is warranted. LGUC appears to remain a common pitfall especially in the suspicious category.

The Paris System "atypical urothelial cells" category: can the current criteria be improved? J Am Soc Cytopathol 2020; 10:3-8.

Abstract
INTRODUCTION The Paris System (TPS) for reporting urine cytology was developed for standardization of diagnosis focusing on the detection of high-grade urothelial carcinoma (HGUC). Probably the most challenging task for TPS is to provide criteria for the atypical urothelial cell (AUC) category. The TPS criteria for AUC include increased nuclear/cytoplasmic (N/C) ratio (>0.5) and 1 of the 3 minor criteria including nuclear hyperchromasia (NH), coarse chromatin (CC) and irregular nuclear membrane (INM). We evaluated TPS-AUC diagnostic value and investigated whether other morphologic parameters can improve its criteria. MATERIALS AND METHODS Urine samples with diagnoses of AUC collected during a 6-month period were re-reviewed. Data captured included N/C ratio >0.5, NH, CC, INM, and 2 additional criteria including enlarged nuclear size (ENS) and the presence of nucleolus (N). ENS was considered when the nucleus was 2 times larger than the urothelial cell or 3 times larger than lymphocyte. RESULTS By applying the TPS-AUC criteria, the rate of atypia diagnosis reduced in comparison to Pre-TPS (9% versus 13%, P = 0.02). Among the AUC minor criteria, NH was the best criterion with the highest interobserver agreement (IOA) and correlation with HGUC (k = 0.342, r = 0.61, P < 0.001) and strong PPV (93.6%). ENS had the highest PPV (95.8%) and, after NH, had the highest IOA and correlation with HGUC (k = 0.29, r = 0.52, P < 0.001). CONCLUSION TPS improves the diagnostic value of urine cytology, particularly in cases with atypia. ENS is a strong criterion for increasing the diagnostic value of AUC and potentially can improve TPS performance as a minor criterion.

Abstract
OBJECTIVE In 2013, The Paris System for Reporting Urinary Cytology (TPS) was developed as a uniform practical urine cytology system that could be applied worldwide. Here, we investigated the effectiveness of TPS diagnostic approach compared with that of the traditional urine cytological diagnosis method used in China. METHODS Based on the diagnostic criteria of TPS, 412 urine samples from 143 patients with histological follow-up data were retrospectively analysed, and the diagnoses were compared with the original cytological diagnoses. RESULTS In total, 110 patients were histologically diagnosed with high-grade urothelial carcinoma (HGUC), and 33 patients were diagnosed with low-grade urothelial neoplasia. Based on the traditional urine cytological analysis method, 50 patients (34.9%) were diagnosed as negative, 48 patients (33.6%) were diagnosed as having atypical urothelial cells, and 45 patients (31.5%) were diagnosed as positive. After reclassification using TPS, urine samples from 11 cases (7.7%) were categorised as unsatisfactory, 34 cases (23.8%) were negative, 21 cases (14.7%) were categorised as having atypical urothelial cells, 12 cases (8.4%) were diagnosed as suspicious for HGUC, 59 cases (41.2%) were diagnosed with HGUC, and six cases (4.2%) were reclassified as having low-grade urothelial neoplasia. Thus, after implementing TPS criteria, the sensitivity for positive malignancy diagnoses (HGUC alone) increased from 38.2% to 50.9%, while the specificity of the diagnosis was barely changed. CONCLUSIONS The Paris System for Reporting Urinary Cytology greatly contributes to the standardisation of urine cytology reports and significantly improves the diagnostic sensitivity for HGUC.

Abstract
INTRODUCTION Urine cytology is an important screening tool of patients for urothelial carcinoma (UC) and follow-up of patients with treated disease. Ease of procurement, cost-effectiveness, and lower turnaround time are the major advantages. OBJECTIVE To compare current system of reporting (CSR) at our institute with The Paris System (TPS) and analyze utility of urine cytology based on TPS reporting in correlation with urine culture and histopathology. MATERIALS AND METHODS One-year retrospective study of 90 cases was undertaken wherein cases presenting with painless hematuria and clinically suspicious of UC were included. Urine cytology slides were reviewed and reported with TPS guidelines. These findings were correlated with histopathological diagnosis and urine culture as indicated. Statistical analysis was done using SPSS 17 software. RESULTS With TPS guidelines, 11.1% and 5.6% cases were reported as high-grade UC (HGUC) and low-grade urothelial neoplasm (LGUN), respectively. Suspicious for HGUC category included 17.8% of cases. The rate of reporting "atypical urothelial cells (AUC)" was significantly lower (11.1%) with TPS on comparison with CSR (16.7%). Histopathological correlation of positive predictive value for HGUC was better (100%) on using TPS when compared with CSR (64.3%). Among 11 cases with microbial growth on urine culture, 9.1% were reported as atypical. Sensitivity and accuracy of TPS in detecting UC were 83.3% and 86.52%, respectively. Both were higher when compared with CSR. CONCLUSION In comparison to CSR, criteria of TPS limit the AUC category and enhance the sensitivity and accuracy of detecting HGUC. Adopting TPS for urinary cytology will ensure uniformity and accuracy of HGUC diagnosis.

Abstract
INTRODUCTION Incorporating urine volume into adequacy assessment was recommended by The Paris System for Reporting Urinary Cytology. The concept was relatively new, however, and supportive studies were sparse. We accordingly aimed to determine the role of urine volume in adequacy assessment and cutoff values for urine samples using ThinPrep (Hologic, Inc, MA) processing. MATERIAL AND METHODS Archived consecutive urine cytology cases (n = 2117) were analyzed. Patient age, sex, collection method, urine volume and fixative (CytoLyt, Hologic, Inc) added, adequacy and diagnoses were documented. Adequate samples were defined as samples with >50 well-preserved, well-visualized urothelial cells. Diagnoses of suspicious and positive for high-grade urothelial carcinoma were combined for analysis. Statistical analysis was performed using IBM SPSS Statistics for Windows. RESULTS There was a correlation between urine volume and the unsatisfactory/less than optimal cellularity versus satisfactory samples (P ≤ 0.001) in voided urine specimens. A minimum of 10 mL of fresh voided urine was found to be a reasonable cutoff to achieve sufficient cellularity. Cutoff values of 30 mL for voided urine for the high-risk diagnosis were associated with the highest χ2 statistic, although this was not statistically significant. CONCLUSIONS Urine volume was justified as an adequacy criterion in voided urine. Although 10 mL of fresh voided urine might achieve sufficient cellularity, higher volume (≥30 mL) is recommended in order to maximize the chance of detecting a high-risk diagnosis. Nevertheless, the presence of high-grade urothelial carcinoma can still be detected in low-volume (<20 mL) specimens. Hence, correlation of clinical information with voided urine volume cutoff values for individual cases might also be beneficial.

Abstract
The utility of urine cytology has shifted from the identification of red blood cells, crystals, or parasites to its currently used role of detection of cancer cells exfoliated in urine samples. A variety of ancillary tests have been developed to complement the diagnostic ability of urine cytology. Furthermore, urine testing will continue to evolve as the pathogenesis of genitourinary tract diseases in depth is understood. This article focuses on the diagnostic advances in urine cytology from the cytomorphological perspective, past and current reporting schemes, and the application of ancillary testing in urine samples.

Abstract
BACKGROUND The Paris System for Reporting Urinary Cytology represents a significant improvement in classification of urinary specimens. The system acknowledges the difficulty in cytologically diagnosing low-grade urothelial carcinomas and has developed categories to deal with this issue. The system uses six categories: unsatisfactory, negative for high-grade urothelial carcinoma (NHGUC), atypical urothelial cells, suspicious for high-grade urothelial carcinoma, high-grade urothelial carcinoma, other malignancies and a seventh subcategory (low-grade urothelial neoplasm). METHODS Three hundred and fifty-seven urine specimens were independently reviewed by four cytopathologists unaware of the previous diagnoses. Each cytopathologist rendered a diagnosis according to the Paris System categories. Agreement was assessed using absolute agreement and weighted chance-corrected agreement (kappa). Disagreements were classified as low impact and high impact based on the potential impact of a misclassification on clinical management. RESULTS The average absolute agreement was 65% with an average expected agreement of 44%. The average chance-corrected agreement (kappa) was 0.32. Nine hundred and ninety-nine of 1902 comparisons between rater pairs were in agreement, but 12% of comparisons differed by two or more categories for the category NHGUC. Approximately 15% of the disagreements were classified as high clinical impact. CONCLUSIONS Our findings indicated that the scheme recommended by the Paris System shows adequate precision for the category NHGUC, but the other categories demonstrated unacceptable interobserver variability. This low level of diagnostic precision may negatively impact the applicability of the Paris System for widespread clinical application.

Non-invasive prediction of recurrence in bladder cancer by detecting somatic TERT promoter mutations in urine. Br J Cancer 2017; 117:583-587.

Abstract
Background: Urothelial bladder cancer (UBC) is characterised by a high risk of recurrence. Patient monitoring is currently based on iterative cystoscopy and on urine cytology with low sensitivity in non-muscle-invasive bladder cancer (NMIBC). Telomerase reverse transcriptase (TERT) is frequently reactivated in UBC by promoter mutations. Methods: We studied whether detection of TERT mutation in urine could be a predictor of UBC recurrence and compared this to cytology/cystoscopy for patient follow-up. A total of 348 patients treated by transurethral bladder resection for UBC were included together with 167 control patients. Results: Overall sensitivity was 80.5% and specificity 89.8%, and was not greatly impacted by inflammation or infection. TERT remaining positive after initial surgery was associated with residual carcinoma in situ. TERT in urine was a reliable and dynamic predictor of recurrence in NMIBC (P<0.0001). In univariate analysis, TERT positive-status after initial surgery increased risk of recurrence by 5.34-fold (P=0.0004). TERT positive-status was still associated with recurrence in the subset of patients with negative cystoscopy (P=0.034). Conclusions: TERT mutations in urine might be helpful for early detection of recurrence in UBC, especially in NMIBC.

Comparison of different concepts for interpretation of chromosomal aberrations in urothelial cells detected by fluorescence in situ hybridization. J Cancer Res Clin Oncol 2016; 143:677-685. [PMID: 27913867 DOI: 10.1007/s00432-016-2310-5] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2016] [Accepted: 11/01/2016] [Indexed: 10/20/2022]
Abstract
PURPOSE Urine fluorescence in situ hybridization (FISH) has become a broadly used marker for noninvasive detection of bladder cancer (BC). However, it has been discussed whether the interpretation algorithm proposed by the manufacturer could be improved. Aim of the present study was to compare alternative evaluation strategies of FISH for detection of BC. METHODS We included 1048 patients suspicious for BC, who underwent urine FISH examination before cystoscopy (diagnostic cohort). Herefrom, we selected 122 patients (prognostic cohort) with a history of non-muscle-invasive BC who were cystoscopically tumor free and received FISH analysis ahead of a follow-up period of 24 months. FISH results were interpreted by the algorithms of UroVysion™, Bubendorf et al. and Zellweger et al. RESULTS In the diagnostic cohort, 228 patients (21.8%) had BC at time of evaluation; in the prognostic cohort 39 patients (32.0%) experienced tumor recurrence. Alterations in chromosome 3, 7 and 17 correlated with the presence of BC. Relative loss of 9p21 was associated with BC and higher risk for progression. The evaluation strategy proposed by Zellweger et al. showed highest accuracy of all FISH assessments. Performance of evaluation strategies differed in voided urine samples and samples obtained after mechanical manipulation. CONCLUSIONS The performance of FISH in BC diagnosis strongly depends on the interpretation criteria. Alternative evaluation methods partly show superior diagnostic performance compared to the manufacturer's algorithm. The introduction of specific cutoffs for tetraploid cells improves specificity. Further modifications of the interpretation algorithm of the Urovysion® FISH assay have the potential to positively affect the value of this test in diagnosis and surveillance of BC.

Abstract
OBJECTIVES We assessed the performance of urine cytology using the Paris System for Reporting Urine Cytology (PSRUC) in comparison to our current system. METHODS In total, 124 specimens with histologic correlation were reviewed and assigned to the PSRUC categories: benign, atypical urothelial cells (AUCs), suspicious for high-grade urothelial carcinoma (SHGUC), and high-grade urothelial carcinoma (HGUC). Original cytological diagnoses were recorded. RESULTS Fewer cases were given an AUC diagnosis using the PSRUC in comparison to the original diagnoses (26% vs 39%), while the association of AUCs with subsequent HGUC increased from 33% to 53% with the PSRUC. Using the PSRUC resulted in a higher number of low-grade carcinomas assigned to the benign (40%) rather than the AUC (22%) category. The performance of SHGUC/HGUC diagnoses was similar in both systems (predictive value = 94%). CONCLUSIONS The PSRUC seems to improve the performance of urine cytology by limiting the AUC category to cases that are more strongly associated with HGUC.

Abstract
The main purpose of urine cytology is to detect high-grade urothelial carcinoma. With this principle in mind, The Paris System (TPS) Working Group, composed of cytopathologists, surgical pathologists, and urologists, has proposed and published a standardized reporting system that includes specific diagnostic categories and cytomorphologic criteria for the reliable diagnosis of high-grade urothelial carcinoma. This paper outlines the essential elements of TPS and the process that led to the formation and rationale of the reporting system. TPS Working Group, organized at the 2013 International Congress of Cytology, conceived a standardized platform on which to base cytologic interpretation of urine samples. The widespread dissemination of this approach to cytologic examination and reporting of urologic samples and the scheme's universal acceptance by pathologists and urologists is critical for its success. For urologists, understanding the diagnostic criteria, their clinical implications, and limitations of TPS is essential if they are to utilize urine cytology and noninvasive ancillary tests in a thoughtful and practical manner. This is the first international/inclusive attempt at standardizing urinary cytology. The success of TPS will depend on the pathology and urology communities working collectively to improve this seminal paradigm shift, and optimize the impact on patient care.

Abstract
The diagnosis of upper tract urothelial carcinoma (UTUC) can be a challenging diagnostic pursuit. To date, there is no large-scale study assessing the statistical utility (eg, sensitivity and specificity) of selective cytology. Herein, we systematically reviewed and meta-analyzed the published literature to evaluate the efficacy of selective cytology for the detection of UTUC in patients with a suspicious clinical profile Selective cytology confers a high specificity but marginal sensitivity for the detection of UTUC. The sensitivity is greater for high-grade UTUC lesions. The statistical assessment of its utility is limited by the heterogeneity and bias of previous studies.

Abstract
INTRODUCTION The pre-analytical step includes sample collection, preparation, transportation and storage in the pathology unit where the diagnosis is performed. The pathologist ensures that pre-analytical conditions are in line with expectations. The lack of standardization for handling cytological samples makes this pre-analytical step difficult to harmonize. Moreover, this step depends on the nature of the sample: fresh liquid or fixed material, air-dried smears, liquid-based cytology. The aim of the study was to review the different practices in French structures of pathology on the pre-analytical phase concerning cytological fluids such as broncho-alveolar lavage (BALF), serous fluids and urine. METHODS A survey was conducted on the basis of the pre-analytical chapter of the ISO 15189 and sent to 191 French pathological structures (105 public and 86 private). RESULTS Fifty-six laboratories replied to the survey. Ninety-five per cent have a computerized management system and 70% a manual on sample handling. The general instructions requested for the patients and sample identification were highly correctly filled with a short time routing and additional tests prescription. By contrast, information are variable concerning the clinical information requested and the type of tubes for collecting fluids and the volumes required as well as the actions taken in case of non-conformity. For the specific items concerning BALF, serous fluids and urine, this survey has shown a great heterogeneity according to sample collection, fixation and of clinical information. CONCLUSION This survey demonstrates that the pre-analytical quality for BALF, serous fluids and urine is not optimal and that some corrections of the practices are recommended with a standardization of numerous steps in order to increase the reproducibility of additional tests such as immunocytochemistry, cytogenetic and molecular biology. Some recommendations have been written.

Abstract
OBJECTIVE To evaluate the effects of cystoscopy on urine cytology and additional cytokeratin-20 (CK-20) staining in patients presenting with gross hematuria. PATIENTS AND METHODS For 83 patients presenting with gross hematuria, spontaneous and instrumented paired urine samples were analyzed. Three patients were excluded. Spontaneous samples were collected within 1 hour before cystoscopy, and the instrumented samples were tapped through the cystoscope. Subsequently, patients underwent cystoscopic evaluation and imaging of the urinary tract. If tumor suspicious lesions were found on cystoscopy or imaging, subjects underwent transurethral resection or ureterorenoscopy. Two blinded uropathological reviewers (DB, KK) evaluated 160 urine samples. Reference standards were results of cystoscopy, imaging, or histopathology. RESULTS Thirty-seven patients (46.3%) underwent transurethral resection or ureterorenoscopy procedures. In 30 patients (37.5%) tumor presence was confirmed by histopathology. The specificity of urine analysis was significantly higher for spontaneous samples than instrumented samples for both cytology alone (94% vs 72%, P = .01) and for cytology combined with CK-20 analysis (98% vs 84%, P = .02). The difference in sensitivity between spontaneous and instrumented samples was not significant for both cytology alone (40% vs 53%) and combined with CK-20 analysis (67% vs 67%). The addition of CK-20 analysis to cytology significantly increases test sensitivity in spontaneous urine cytology (67% vs 40%, P = .03). CONCLUSION Instrumentation significantly decreases specificity of urine cytology. This may lead to unnecessary diagnostic procedures. Additional CK-20 staining in spontaneous urine cytology significantly increases sensitivity but did not improve the already high specificity. We suggest performing urine cytology and CK-20 analysis on spontaneously voided urine.

Abstract
INTRODUCTION The diagnosis "atypical urothelial cells (AUC)" remains an unresolved problem, making many urologists dissatisfied and confused about the management strategy on these cases. To date, a few inspiring attempts were made to subclassify AUC into "atypical urothelial cells of undetermined significance" (AUC-US) and "atypical urothelial cells cannot exclude high grade" (AUC-H). The aim of our study was to investigate the most predictive for high-grade urothelial carcinoma (HGUC) cytomorphologic parameters and whether the proposed classification can be implemented in our institution. MATERIAL AND METHODS The electronic medical record system was searched for cytology specimens that were diagnosed as AUC from January 1, 2005 to March 1, 2013 and their relative clinical-pathological follow-up. All specimens were reviewed by an experienced cytopathologist by using 20 published "most predictive" for HGUC criteria. RESULTS A total of 162 AUC specimens were reclassified into 3 groups: AUC-H (n = 45), AUC-US (n = 51), and "negative for malignancy" (n = 66). The reclassification of AUC-H and "negative for malignancy" had 79% sensitivity, 77% specificity, 60% positive predictive value, and 89% negative predictive value to histologically proven HGUC diagnosis. CONCLUSIONS Our study demonstrated a good correlation between the presence of "HGUC-predictive" cytologic criteria and the final biopsy-proven HGUC in cytologic cases originally diagnosed as "atypical urothelial cells present." We identified 2 of the most predictive for HGUC on follow-up cytomorphologic parameters such as increased nuclear-cytoplasmic ratio >0.7 and coarse chromatin (16 abnormal cells per slide in average). These parameters, along with positive fluorescent in situ hybridization results can help during cytologic evaluation of urine specimens.

Abstract
Background The role of urine markers in the surveillance of patients with non-muscle invasive bladder cancer (NMIBC) is discussed extensively. In case of negative cystoscopy the additional prognostic value of these markers has not been clearly defined yet. The present study is the first systematic approach to directly compare the ability of a urine marker panel to predict the risk of recurrence and progression in bladder cancer (BC) patients with no evidence of relapse during surveillance for NMIBC. Methods One hundred fourteen patients who underwent urine marker testing during surveillance for NMIBC and who had no evidence of BC recurrence were included. For all patients cytology, Fluorescence-in-situ-hybridization (FISH), immunocytology (uCyt+) and Nuclear matrix protein 22 enzyme-linked immunosorbent assay (NMP22) were performed. All patients completed at least 24 months of endoscopic and clinical follow-up of after inclusion. Results Within 24 months of follow-up, 38 (33.0%) patients experienced disease recurrence and 11 (9.8%) progression. Recurrence rates in patients with positive vs. negative cytology, FISH, uCyt+ and NMP22 were 52.6% vs. 21.9% (HR = 3.9; 95% CI 1.75-9.2; p < 0.001), 47.6% vs. 25.0% (HR 2.7; 1.2-6.2; p = 0.01), 43.8% vs. 22.4% (HR 3.3; 1.5-7.6; p = 0.003) and 43.8% vs. 16.7% (HR 4.2; 1.7-10.8; p = 0.001). In patients with negative cytology, a positive NMP22 test was associated with a shorter time to recurrence (p = 0.01), whereas FISH or uCyt+ were not predictive of recurrence in these patients. In the group of patients with negative cytology and negative NMP22, only 13.5% and 5.4% developed recurrence and progression after 24 months. Conclusions Patients with positive urine markers at time of negative cystoscopy are at increased risk of recurrence and progression. In patients with negative cytology, only NMP22 is predictive for recurrence. Patients with negative marker combinations including NMP22 harbour a low risk of recurrence. Therefore, the endoscopic follow-up regimen may be attenuated in this group of patients.

Abstract
INTRODUCTION Adequacy criteria are well established in some areas of cytopathology to prevent false negative diagnoses. To date, no such criteria have been proposed and validated for urinary tract specimens. Our aim was to determine a cellularity cutoff point that significantly affects the sensitivity of detecting high-grade or in situ urothelial carcinoma (HGUC or UCIS) in bladder barbotage/washing specimens. MATERIALS AND METHODS Bladder barbotage specimens collected in liquid-based media were selected. Specimens diagnosed as "positive for HGUC" (with histologic confirmation) composed the study group, with negative cases as control specimens. Samples were serially diluted and ThinPrep slides of decreasing cellularity were made and reviewed for diagnosis and cellularity. In a retrospective validation study, we identified cases with a "negative for malignancy" bladder barbotage/washing and a surgical pathology diagnosis of UCIS or HGUC (ie, false negative cytology). Cellularity was assessed. RESULTS A distinct difference in sensitivity was noted at a cutoff point of 2644 (20 per 10 high-power fields) urothelial cells. Sensitivities increased for atypical or higher (68.3% versus 100%) and HGUC (43.3% versus 88.0%) after application of this cutoff point with high statistical significance (P = 0.001 and 0.0001, respectively). For the retrospective review, cases below the cutoff point were reclassified as unsatisfactory, and sensitivity rose from 76.3% to 84.8% (P = 0.0027). CONCLUSIONS Our results indicate that, in the absence of atypical or malignant cells, an adequate bladder barbotage specimen should have a minimum of 2644 (20 per 10 high-power fields) well-visualized, well-preserved urothelial cells to increase the positive predictive value of this test.

Abstract
OBJECTIVES To determine the combination of urinary protein markers for noninvasive detection of primary and recurrent urothelial bladder carcinomas. METHODS Urinary concentrations of 27 biomarkers (NSE, ATT, AFABP, Resistin, Midkine, Clusterin, Uromodulin, ZAG2, HSP27, HSP 60, NCAM1/CD56, Angiogenin, Calreticulin, Chromogranin A, CEACAM1, CXCL1, IL13Ra2, Progranulin, VEGFA, CarbAnhydIX, Annexin-V, TIM4, Galectin1, Cystatin B, Synuclein G, ApoA1 and ApoA2) were assessed by enzyme-linked immunosorbent assay or by electrochemiluminiscence immunoassay. RESULTS During the primary diagnostics, a group of 70 patients with primary occurrence of bladder cancer and 49 healthy control subjects were compared. For this clinical situation, the most accurate combination proved to be the combination of cytology with markers Midkine and Synuclein G (sensitivity 91.8%, specificity 97.5%). During the monitoring of patients with non-muscle invasive bladder cancer (NMIBC), a group of 44 patients with cancer recurrence was compared with the group of 61 patients with a history of NMIBC without current disease. For this clinical situation, the most accurate combination proved to be the combination of cytology and erythrocytes count in urine sediment with markers Midkine, ZAG2, CEACAM1, and Synuclein G (sensitivity 92.68%, specificity 90.16%). A lower accuracy of the diagnostic panel and the necessity to use more markers in the case of recurrence was connected with a different structure of patients. CONCLUSIONS Multi-marker test can significantly improve the bladder cancer detection both during the primary diagnostics and monitoring of patients with NMIBC. This outcome should result in other, larger studies.

Abstract
OBJECTIVE The diagnosis of low-grade papillary urothelial carcinoma (LGPUC) in urine cytology specimens is challenging because of its subtle, minimally atypical findings. Furthermore, as SurePath(™) liquid-based cytology (LBC) is becoming a widely used method in urine cytology, the inevitable cytomorphological alterations resulting from this technique call for new morphological diagnostic criteria in LGPUC. METHODS Logistic regression analysis was carried out on SurePath slides from surgically proven voided urine specimens. The study was designed to include a test set (n = 141) and a validation set (n = 61), and evaluated significant discriminative parameters between LGPUC and benign papillary urothelial neoplasm (BPUN). RESULTS Of the seven cytological findings that were found to have statistical significance in univariate analysis, five were found to be independent variables: loss of polarity of papillaroid clusters, irregular contours, absence of columnar cells, hobnail features and hyperchromasia. These independent variables had an area under the curve (AUC) of 0.781. CONCLUSIONS The distinctive cytological criteria identified above may prove to be helpful in cases in which other conventional criteria for LGPUC are insufficient for diagnosis.

Stepwise application of urine markers to detect tumor recurrence in patients undergoing surveillance for non-muscle-invasive bladder cancer. DISEASE MARKERS 2014; 2014:973406.

Abstract
Background. The optimal use of urine markers in the surveillance of non-muscle-invasive bladder cancer (NMIBC) remains unclear. Aim of the present study was to investigate the combined and stepwise use of the four most broadly available urine markers to detect tumor recurrence in patients undergoing surveillance of NMIBC.
Patients and Methods. 483 patients with history of NMIBC were included. Cytology, UroVysion, fluorescence in situ hybridization (FISH), immunocytology (uCyt+), and NMP22 ELISA were performed before surveillance cystoscopy. Characteristics of single tests and combinations were assessed by contingency analysis. Results. 128 (26.5%) patients had evidence of tumor recurrence. Sensitivities and negative predictive values (NPVs) of the single tests ranged between 66.4–74.3 and 82.3–88.2%. Two-marker combinations showed sensitivities and NPVs of 80.5–89.8 and 89.5–91.2%. A stepwise application of the two-test combinations with highest accuracy (cytology and FISH; cytology and uCyt+; uCyt+ and FISH) showed NPVs for high-risk recurrences (G3/Cis/pT1) of 98.8, 98.8, and 99.1%, respectively. Conclusions. Combinations of cytology, FISH, immunocytology, and NMP22 show remarkable detection rates for recurrent NMIBC. Stepwise two-test combinations of cytology, FISH, and immunocytology have a low probability of missing a high-risk tumor. The high sensitivities may justify the use of these combinations in prospective studies assessing the use of urine markers to individualize intervals between cystoscopies during follow-up.

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.

Abstract
The newest installment on state-of-the-art standards of practice in cytopathology from the Papanicolaou Society of Cytopathology (PSC) focuses on the pancreaticobiliary system. Similar to the National Cancer Institute recommendations for aspiration cytology of the thyroid, the PSC guidelines for pancreaticobiliary cytology addresses indications, techniques, terminology and nomenclature, ancillary studies, and postprocedure management. Each committee was composed of a multidisciplinary group of experts in diagnosing, managing, and treating patients with pancreaticobiliary disease. Draft documents were posted on an interactive Web-based forum hosted by the PSC Web site (www.papsociety.org) and the topics of terminology, ancillary testing, and management were presented at national and international meetings over an 18-month period for discussion and feedback from practicing pathologists around the world. This review provides a synopsis of these guidelines.
