Incidental Diagnosis of Urothelial Bladder Cancer: Associations with Overall Survival. Cancers (Basel) 2023; 15:cancers15030668. [PMID: 36765629 PMCID: PMC9913049 DOI: 10.3390/cancers15030668] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 01/07/2023] [Accepted: 01/18/2023] [Indexed: 01/24/2023] Open
Abstract
BACKGROUND We investigated whether an incidental diagnosis (ID) of bladder cancer (BC) was associated with improved survival. METHODS We retrospectively reviewed data of consecutive patients with no prior diagnosis of urothelial cancer who underwent a primary transurethral resection of bladder tumor (pTURBT) between January 2013 and February 2021 and were subsequently diagnosed with urothelial BC. The type of diagnosis (incidental or non-incidental) was identified. Overall, relative, recurrence-free, and progression-free survival rates (OS, RS, RFS, and PFS) after pTURBT were evaluated using the Kaplan-Meier curves and long-rank tests. A multivariable Cox regression model for the overall mortality was developed. RESULTS A total of 435 patients were enrolled. The median follow-up was 2.7 years. ID cases were more likely to be low-grade (LG) and non-muscle-invasive. ID vs. non-ID was associated with a trend toward an improved 7-year OS (66% vs. 49%, p = 0.092) and a significantly improved 7-year OS, if incidental cases were limited to ultrasound-detected tumors (75% vs. 49%, p = 0.013). ID was associated with improved survival among muscle-invasive BC (MIBC) patients (3-year RS: 97% vs. 23%, p < 0.001), but not among other subgroups stratified according to disease stage or grade. In multivariable analysis, only age, MIBC, and high-grade (HG) cancer demonstrated an association with mortality. PFS and RFS among non-MIBC patients did not differ in regard to the type of diagnosis. CONCLUSIONS Incidental diagnosis may contribute to an improved survival in BC patients, most probably in the mechanism of the relative downgrading of the disease, including the possible overdiagnosis of LG tumors. Nevertheless, in the subgroup analyses, we noted marked survival benefits in MIBC cases. Further prospective studies are warranted to gain a deeper understanding of the observed associations.

Abstract
<b><i>Introduction:</i></b> The aim of this study was to evaluate the prevalence and clinical features of incidental bladder cancer (BC) diagnosis, with special emphasis on possible associations between incidental diagnosis and primary disease stage or grade. <b><i>Methods:</i></b> We retrospectively included 501 consecutive patients who underwent transurethral resection of bladder tumor and were diagnosed with primary urothelial carcinoma of the bladder between January 2013 and February 2021 in a university hospital. The type of diagnosis (incidental or nonincidental), patient baseline characteristics and primary stage and grade were studied for interdependencies. <b><i>Results:</i></b> 28.5% of all patients and 19.8% of high grade (HG) BC patients had been diagnosed incidentally, most commonly with ultrasound. Incidental diagnosis was associated with lower primary stage and grade of the disease. Most importantly, on multivariable analysis, which included baseline patient characteristics and type of diagnosis, in the subgroup of HG BC patients, muscle-invasive BC (MIBC) or metastatic disease was three times less likely to be diagnosed incidentally than non-MIBC (odds ratio: 0.31, 95% confidence interval: 0.14–0.71, <i>p</i> = 0.006). <b><i>Conclusions:</i></b> The study is first to demonstrate that incidental diagnosis of HG BC may be surprisingly prevalent and associated with lower rates of muscle invasion or metastatic disease.

Abstract
OBJECTIVES With the advent of novel genomic and transcriptomic technologies, new urinary biomarkers have been identified and tested for bladder cancer (BCa) surveillance. To summarize the current status of urinary biomarkers for the detection of recurrence and/or progression in the follow-up of non-muscle invasive BCa patients, and to assess the value of urinary biomarkers in predicting response to intravesical Bacillus Calmette-Guerin (BCG) therapy. METHODS AND MATERIALS A medline/pubmed© literature search was performed. The performance of commercially available and investigational biomarkers has been reviewed. End points were cancer detection (recurrence), cancer progression, and response to BCG therapy. RESULTS The performance requirements for biomarkers are variable according to the clinical scenario. The clinical role of urinary biomarkers in the follow-up of non-muscle invasive BCa patients remains undefined. The FDA-approved tests provide unsatisfactory sensitivity and specificity levels and their use is limited. Fluorescence in situ hybridization (FISH) has been shown to be useful in specific scenarios, mostly as a reflex test and in the setting of equivocal urinary cytology. FISH and immunocytology could conceivably be used to assess BCG response. Recently developed biomarkers have shown promising results; upcoming large trials will test their utility in specific clinical scenarios in a manner similar to a phased drug development strategy. CONCLUSIONS Current commercially available urinary biomarker-based tests are not sufficiently validated to be widely used in clinical practice. Several novel biomarkers are currently under investigation. Prospective multicenter analyses will be needed to establish their clinical relevance and value.

Ahn JS, Kim HS, Chang SG, Jeon SH. The clinical usefulness of nuclear matrix protein-22 in patients with atypical urine cytology. Korean J Urol 2011; 52:603-6. [PMID: 22025954 PMCID: PMC3198232 DOI: 10.4111/kju.2011.52.9.603] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2011] [Accepted: 07/22/2011] [Indexed: 11/18/2022] Open
Abstract
Purpose Difficulty exists in interpreting the significance of atypical urine cytology. This study was performed to assess the diagnostic utility of nuclear matrix protein-22 (NMP-22) testing when atypical cells are detected during urine cytology. Materials and Methods Among patients whose urine cytology was reported as atypical between January 2004 and December 2009, a total of 275 who also underwent NMP-22 testing were enrolled in the present study. These patients were further divided into the screening group (143 patients examined as outpatients for hematuria) and the follow-up group (132 patients followed up for previously diagnosed bladder cancer). The sensitivity, specificity, positive and negative predictive values, and accuracy were assessed for atypical cytology alone and in conjunction with NMP-22. Results Of the 275 patients exhibiting atypical urine cytology, cancer was confirmed in 85, yielding a positive predictive value of 30.9% (85/275). Of the 96 patients testing positive for NMP-22, 58 were diagnosed with bladder cancer. The positive predictive value in conjunction with NMP-22 was 60.4% (58/96). The sensitivity, specificity, negative predictive value, and accuracy were 68.2% (58/85), 80.0% (152/190), 84.9% (152/179), and 76.2% (210/275), respectively. Testing for NMP-22 in the screening and follow-up groups increased the positive predictive value from 30.0% (43/143) to 64.0% (32/50) and from 31.3% (42/132) to 56.5% (26/46), respectively; there was no significant difference between the screening and follow-up groups (p=0.106). Conclusions When only cases with atypical urine cytology were examined, NMP-22 testing increased the detection rate of bladder cancer regardless of whether the test was used in screening hematuria or in following up patients.

Abstract
INTRODUCTION Diagnosis and follow-up of bladder cancer is based on cytology and cystoscopic exams. Cytology is highly specific but remains with a highly variable sensitivity. Cystoscopy is an invasive exam and has shown specific limits. Urinary test, highly specific and highly sensitive, might be ideal to replace the couple cytology-cystoscopy. MATERIAL AND METHODS Through a literature review, using MeSH system and Pubmed system (keywords: NMP22 and bladder cancer), authors pointed to the value of NMP22 to replace cystoscopy and cytology. RESULTS Between 1996 and 2010, 193 publications were identified with these keywords. Seventeen original articles have been selected based on their quality and methodology. NMP22 was more sensitive than cytology for follow-up and screening of bladder cancer. As screening test, NMP22 has shown positive predictive value between 0 and 70%. As follow-up test, NMP22 has shown more stable positive predictive value close to 70%. Coupled to cytology, NMP22 has shown predictive positive value up to 90%. CONCLUSION For screening test, NMP22 should be the referent test for best selection cases (tobacco, hematuria) and for systemic elimination of false positive cases (ureteral stent, lithiasis). For follow-up test, NMP22-cytology should be the new reference. Moreover, when NMP22 is positive with negative cystoscopy, follow-up may be carefully proposed (recurrence risk×10).

Abstract
BACKGROUND Cystoscopy with urinary cytology is the gold standard for the diagnosis and follow-up of patients with tumors of the urinary bladder. The aim of the study was to evaluate the performance of the nuclear matrix protein 22 (NMP22) tumor marker test, BladderChek® point-of-care test and voided urinary cytology for the detection and follow-up of bladder tumors. METHODS NMP22 was measured using an ELISA assay in stabilized voided urine and using the BladderChek® test. Voided urinary cytology was performed on urine samples. Results were compared to cystoscopic findings and histopathological examination results after transurethral resection of the bladder lesion. RESULTS For the prediction of malignant histopathological result, sensitivity and specificity were 45.2% and 75.0%, respectively, for NMP22 at a cut-off of 7.5 kU/L, 17.7% and 100% for the BladderChek® test and 37.0% and 100% for voided urine cytology. For the prediction of suspicious or positive cystoscopic finding, sensitivity and specificity were 40.4% and 72.1%, respectively, for NMP22 at a cut-off of 7.5 kU/L, 14.8% and 93.8% for the BladderChek® test and 26.8% and 98.1% for voided urine cytology. CONCLUSIONS The NMP22 quantitative test showed higher sensitivity and lower specificity compared with voided urine cytology, whereas the sensitivity of the BladderChek® test was low. We could not recommend any of the three non-invasive tests as a replacement for cystoscopy for the diagnosis or follow-up of urinary bladder tumors.

Abstract
BACKGROUND Although several cancer biomarkers are now in use, few have the necessary sensitivity and specificity to eliminate the need for invasive diagnostic procedures. With the expansion of proteomics, new technologies have been used to study various cancers, resulting in the discovery of several potential urine biomarkers. Urine is an ideal medium for the detection of biomarkers because of the non-invasive means of collecting samples and demonstrated shedding of cells, proteins, enzymes, nucleic acids and metabolic products into urine during various pathological processes. OBJECTIVE To review the contemporary literature regarding urinary protein markers of cancer. METHODS A PubMed search for 'urinary protein biomarkers of cancer' revealed 4679 scientific publications. The search was limited to studies published over the last 5 years and reviewed pertinent findings regarding biomarker evaluation and discovery. RESULTS Several urinary protein biomarkers have been described for urologic, gynecologic, gastrointestinal and neurologic tumors. Some have been selected for use in clinical practice, whereas others have been abandoned owing to inconclusive follow-up studies. CONCLUSION Several potential urinary protein markers for cancer exist, yet multi-institutional, prospective trials are needed to validate results before implementation in clinical scenarios.
