A New Method of Artificial-Intelligence-Based Automatic Identification of Lymphovascular Invasion in Urothelial Carcinomas. Diagnostics (Basel) 2024; 14:432. [PMID: 38396472 PMCID: PMC10888137 DOI: 10.3390/diagnostics14040432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 02/07/2024] [Accepted: 02/14/2024] [Indexed: 02/25/2024] Open
Abstract
The presence of lymphovascular invasion (LVI) in urothelial carcinoma (UC) is a poor prognostic finding. This is difficult to identify on routine hematoxylin-eosin (H&E)-stained slides, but considering the costs and time required for examination, immunohistochemical stains for the endothelium are not the recommended diagnostic protocol. We developed an AI-based automated method for LVI identification on H&E-stained slides. We selected two separate groups of UC patients with transurethral resection specimens. Group A had 105 patients (100 with UC; 5 with cystitis); group B had 55 patients (all with high-grade UC; D2-40 and CD34 immunohistochemical stains performed on each block). All the group A slides and 52 H&E cases from group B showing LVI using immunohistochemistry were scanned using an Aperio GT450 automatic scanner. We performed a pixel-per-pixel semantic segmentation of selected areas, and we trained InternImage to identify several classes. The DiceCoefficient and Intersection-over-Union scores for LVI detection using our method were 0.77 and 0.52, respectively. The pathologists' H&E-based evaluation in group B revealed 89.65% specificity, 42.30% sensitivity, 67.27% accuracy, and an F1 score of 0.55, which is much lower than the algorithm's DCC of 0.77. Our model outlines LVI on H&E-stained-slides more effectively than human examiners; thus, it proves a valuable tool for pathologists.

Abstract
Emerging data on T1 bladder cancer subcategorization (aka substaging) suggests a correlation with oncological outcomes. The International Society of Urological Pathology (ISUP) organized the 2022 consensus conference in Basel, Switzerland to focus on current issues in bladder cancer and tasked working group 3 to make recommendations for T1 subcategorization in transurethral bladder resections. For this purpose, the ISUP developed and circulated a survey to their membership querying approaches to T1 bladder cancer subcategorization. In particular, clinical relevance, pathological reporting, and endorsement of T1 subcategorization in the daily practice of pathology were surveyed. Of the respondents of the premeeting survey, about 40% do not routinely report T1 subcategory. We reviewed literature on bladder T1 subcategorization, and screened selected articles for clinical performance and practicality of T1 subcategorization methods. Published literature offered evidence of the clinical rationale for T1 subcategorization and at the conference consensus (83% of conference attendants) was obtained to report routinely T1 subcategorization of transurethral resections. Semiquantitative T1 subcategorization was favored (37%) over histoanatomic methods (4%). This is in line with literature findings on practicality and prognostic impact, that is, a shift of publications from histoanatomic to semiquantitative methods or by reports incorporating both methodologies is apparent over the last decade. However, 59% of participants had no preference for either methodology. They would add a comment in the report briefly stating applied method, interpretation criteria (including cutoff), and potential limitations. When queried on the terminology of T1 subcategorization, 34% and 20% of participants were in favor of T1 (microinvasive) versus T1 (extensive) or T1 (focal) versus T1 (nonfocal), respectively.

Abstract
BACKGROUND The existence and prognosis of T1LG (T1 low-grade) bladder cancer is controversial. Also, because of data paucity, it remains unclear what is the clinical history of bacillus Calmette-Guérin (BCG) treated T1LG tumors and if it differs from other NMIBC (non-muscle-invasive bladder cancer) representatives. The aim of this study was to analyse recurrence-free survival (RFS) and progression-free survival (PFS) in patients with T1LG bladder cancers treated with BCG immunotherapy. METHODS A multi-institutional and retrospective study of 2510 patients with Ta/T1 NMIBC with or without carcinoma in situ (CIS) treated with BCG (205 T1LG patients) was performed. Kaplan-Meier estimates and log-rank test for RFS and PFS to compare the survival between TaLG, TaHG, T1LG, and T1HG NMIBC were used. Also, T1LG tumors were categorized into EAU2021 risk groups and PFS analysis was performed, and Cox multivariate model for both RFS and PFS were constructed. RESULTS The median follow-up was 52 months. For the T1LG cohort, the estimated RFS and PFS rates at 5-year were 59.3% and 89.2%, respectively. While there were no differences in RFS between NMIBC subpopulations, a slightly better PFS was found in T1LG NMIBC compared to T1HG (5-year PFS; T1LG vs. T1HG: 82% vs. 89%; P<0.001). A heterogeneous classification of patients with T1LG NMIBC was observed when EAU 2021 prognostic model was applied, finding a statistically significant worse PFS in patients classified as high-risk T1LG (5-year PFS; 81.8%) compared to those in intermediate (5-year PFS; 93,4%), and low-risk T1LG tumors (5-year PFS; 98,1%). CONCLUSIONS The RFS of T1LG was comparable to other NMIBC subpopulations. The PFS of T1LG tumors was significantly better than of T1HG NMIBC. The EAU2021 scoring model heterogeneously categorized the risk of progression in T1LG tumors and the high-risk T1LG had the worst PFS.

T1G1 Bladder Cancer: Prognosis for this Rare Pathological Diagnosis Within the Non-muscle-invasive Bladder Cancer Spectrum. Eur Urol Focus 2022; 8:1627-1634. [PMID: 35577750 DOI: 10.1016/j.euf.2022.04.014] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Revised: 04/13/2022] [Accepted: 04/25/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND The pathological existence and clinical consequence of stage T1 grade 1 (T1G1) bladder cancer are the subject of debate. Even though the diagnosis of T1G1 is controversial, several reports have consistently found a prevalence of 2-6% G1 in their T1 series. However, it remains unclear if T1G1 carcinomas have added value as a separate category to predict prognosis within the non-muscle-invasive bladder cancer (NMIBC) spectrum. OBJECTIVE To evaluate the prognostic value of T1G1 carcinomas compared to TaG1 and T1G2 carcinomas within the NMIBC spectrum. DESIGN, SETTING, AND PARTICIPANTS Individual patient data for 5170 primary Ta and T1 bladder tumors from 17 hospitals in Europe and Canada were analyzed. Transurethral resection (TUR) was performed between 1990 and 2018. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Time to recurrence and progression were analyzed using cumulative incidence functions, log-rank tests, and multivariable Cox regression models stratified by institution. RESULTS AND LIMITATIONS T1G1 represented 1.9% (99/5170) of all carcinomas and 5.3% (99/1859) of T1 carcinomas. According to primary TUR dates, the proportion of T1G1 varied between 0.9% and 3.5% per year, with similar percentages in the early and later calendar years. We found no difference in time to recurrence between T1G1 and TaG1 (p = 0.91) or between T1G1 and T1G2 (p = 0.30). Time to progression significantly differed between TaG1 and T1G1 (p < 0.001) but not between T1G1 and T1G2 (p = 0.30). Multivariable analyses for recurrence and progression showed similar results. CONCLUSIONS The relative prevalence of T1G1 diagnosis was low and remained constant over the past three decades. Time to recurrence of T1G1 NMIBC was comparable to that for other stage/grade NMIBC combinations. Time to progression of T1G1 NMIBC was comparable to that for T1G2 but not for TaG1, suggesting that treatment and surveillance of T1G1 carcinomas should be more like the approaches for T1G2 NMIBC in accordance with the intermediate and/or high risk categories of the European Association of Urology NMIBC guidelines. PATIENT SUMMARY Although rare, stage T1 grade 1 (T1G1) bladder cancer is still diagnosed in daily clinical practice. Using individual patient data from 17 centers in Europe and Canada, we found that time to progression of T1G1 cancer was comparable to that for T1G2 but not TaG1 cancer. Therefore, our results suggest that primary T1G1 bladder cancers should be managed with more aggressive treatment and more frequent follow-up than for low-risk bladder cancer.

Abstract
CONTEXT.— Despite continued surveillance and intravesical therapy, a significant subset of patients with lamina propria-invasive bladder cancer (T1) will progress to muscle-invasive disease or metastases. OBJECTIVE.— To analyze the value of pathologic subcategorization of T1 disease in predicting progression. DESIGN.— Six substaging methods were applied to a retrospective cohort of 73 patients, with pT1 urothelial carcinoma diagnosed on biopsy/transurethral resection. Additionally, the immunohistochemistry for GATA3 and cytokeratin 5/6 (CK5/6) was performed to study the prognostic value of stratifying T1 cancers into luminal or basal phenotypes. RESULTS.— On follow-up (mean, 46 months), 21 (29%) experienced at least 1 recurrence without progression, and 16 (22%) had progression to muscle-invasive disease and/or distant metastasis. No differences were noted between progressors and nonprogressors with regard to sex, age, treatment status, medical history, tumor grade, and presence of carcinoma in situ. Substaging using depth of invasion (cutoff ≥1.4 mm), largest invasive focus (≥3.6 mm), aggregate linear length of invasion (≥8.9 mm), and number of invasive foci (≥3 foci) correlated significantly with progression and reduced progression-free survival, whereas invasion into muscularis mucosa or vascular plexus, or focal versus extensive invasion (focal when ≤2 foci, each <1 mm) failed. Patients with luminal tumors had higher incidence of progression than those with nonluminal tumors (27% versus 11%), although the difference was statistically insignificant (P = .14). CONCLUSIONS.— Substaging of T1 bladder cancers should be attempted in pathology reports. Quantifying the number of invasive foci (≥3) and/or measuring the largest contiguous focus of invasive carcinoma (≥3.6 mm) are practical tools for prognostic substaging of T1 cancers.

Abstract
OBJECTIVE To assess the value of second-look resection (SLR) in stage T1 bladder cancer (BCa) with respect to progression-free survival (PFS), and also the secondary outcomes recurrence-free survival (RFS), bladder-cancer-specific survival (CSS), and cystectomy-free survival (CFS). PATIENTS AND METHODS The study included 2456 patients diagnosed with stage T1 BCa 2004-2009 with 5-yr follow-up registration in the nationwide Bladder Cancer Data Base Sweden (BladderBaSe). PFS, RFS, CSS, and CFS were evaluated in stage T1 BCa patients with or without routine SLR, using univariate and multivariable Cox regression with adjustment for multiple confounders (age, gender, tumour grade, intravesical treatment, hospital volume, comorbidity, and educational level). RESULTS SLR was performed in 642 (26%) individuals, and more frequently on patients who were aged < 75 yr, had grade 3 tumours, and had less comorbidity. There was no association between SLR and PFS (hazard ratio [HR] 1.1, confidence interval [CI] 0.85-1.3), RFS (HR 1.0, CI 0.90-1.2), CFS (HR 1.2, CI 0.95-1.5) or CSS (HR 1.1, CI 0.89-1.4). CONCLUSIONS We found similar survival outcomes in patients with and patients without SLR, but our study is likely affected by selection mechanisms. A randomised study defining the role of SLR in stage T1 BCa would be highly relevant to guide current praxis.

Impact of Lymphovascular Invasion on Prognosis in the Patients with Bladder Cancer-Comparison of Transurethral Resection and Radical Cystectomy. Diagnostics (Basel) 2021; 11:diagnostics11020244. [PMID: 33557407 PMCID: PMC7915441 DOI: 10.3390/diagnostics11020244] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 01/28/2021] [Accepted: 02/02/2021] [Indexed: 02/08/2023] Open
Abstract
(1) Background: This study aimed to evaluate the associations of lymphovascular invasion (LVI) at first transurethral resection of bladder (TURBT) and radical cystectomy (RC) with survival outcomes, and to evaluate the concordance between LVI at first TURBT and RC. (2) Methods: We analyzed 216 patients who underwent first TURBT and 64 patients who underwent RC at Toho University Sakura Medical Center. (3) Results: LVI was identified in 22.7% of patients who underwent first TURBT, and in 32.8% of patients who underwent RC. Univariate analysis identified ≥cT3, metastasis and LVI at first TURBT as factors significantly associated with overall survival (OS) and cancer-specific survival (CSS). Multivariate analysis identified metastasis (hazard ratio (HR) 6.560, p = 0.009) and LVI at first TURBT (HR 9.205, p = 0.003) as significant predictors of CSS. On the other hand, in patients who underwent RC, ≥pT3, presence of G3 and LVI was significantly associated with OS and CSS in univariate analysis. Multivariate analysis identified inclusion of G3 as a significant predictor of OS and CSS. The concordance rate between LVI at first TURBT and RC was 48.0%. Patients with positive results for LVI at first TURBT and RC displayed poorer prognosis than other patients (p < 0.05). (4) Conclusions: We found that the combination of LVI at first TURBT and RC was likely to provide a more significant prognostic factor.

Abstract
Background The assessment of lymphovascular invasion (LVI) on the specimens of a transurethral resection of bladder tumors (TURBT) is very important for risk stratification and decision-making on further treatment for bladder cancer. Objectives The present study aimed to identify clinical predictors associated with the risk of bladder cancer with LVI before a first TURBT. Methods A total of 291 patients underwent a first TURBT for bladder cancer at Toho University Sakura Medical Center between January 2012 and December 2016. We analyzed predictors of LVI based on data from 217 patients and predictors of high grade and ≥ pT1 tumors based on data from the medical records of 237 patients for comparison with LVI risk factors. Results Univariate analysis significantly associated LVI with episodes of gross hematuria, positive urinary cytology, and larger, non-papillary and sessile tumors. Multivariate analysis selected larger tumors [odds ratio (OR) 1.39; 95 % confidence interval (CI) 1.08-1.78; p = 0.01], and non-papillary (OR 10.05; 95% CI 3.75-26.91; p < 0.01) and sessile (OR 2.65; 95% CI 1.18-5.93; p = 0.02) tumors as significant predictors of LVI. Some predictors such as tumor size and non-papillary tumors overlapped between high-grade and ≥ pT1 bladder cancer. Conclusions These predictors can help clinicians to identify patients with, or who are at high-risk for LVI before undergoing a first TURBT and to determine priorities for preoperative evaluation and scheduling consecutive treatments.

Abstract
INTRODUCTION The efficiency of the T1 sub-staging system on categorizing bladder cancer (BC) patients into subgroups with different clinical outcomes was unclear. We summarized relevant evidences, including recurrence-free survival (RFS), progression-free survival (PFS), and cancer-specific survival (CSS), to analyze the prognostic significance of T1 sub-stage. METHODS Systematic literature searches of MEDLINE, EMBASE, and the Cochrane Library were performed. We pooled data on recurrence, progression, and CSS from 35 studies. RESULTS The pooled hazard ratios (HRs) and 95% confidence intervals (CIs) indicated the difference in RFS between T1a sub-stage and T1b sub-stage (HR 1.28, 95% CI 1.14-1.43, p < 0.001). The significant difference was observed in PFS between the 2 arms (HR 2.18, 95% CI 1.95-2.44, p < 0.001). Worse CSS was found in T1b patients than in T1a patients (HR 1.36, 95% CI 1.21-1.54, p < 0.001). CONCLUSIONS T1 sub-staging system based on the invasion depth into muscularis mucosae can be a significant prognostic factor for RFS, PFS, and CSS of patients with T1 BC. Urologists and pathologists are encouraged to work together to give a precise sub-stage classification of T1 BC, and T1 sub-staging system should be a routine part of any histopathological report when possible. Different treatment strategies need to be developed for both T1a BC and T1b BC.

Abstract
INTRODUCTION T1 bladder cancer is associated with a high risk of recurrence and progression; concomitant carcinoma in situ and/or multifocality are negative prognostic factors. Persistent disease after resection of T1 tumours has been observed in 33-55% of patients, and after resection of High-grade (HG) Ta tumour in 41,4%. It has been demonstrated that a second TURB can increase recurrence-free survival and it can make a restaging of the cancer. PATIENTS AND METHODS From January 2011 to December 2016, 87 patients with superficial bladder tumor (Ta-T1), undergoing TURB and routine repeat TURB (Re-TURB) 4-6 weeks after the initial resection, were included in the study. Re-TURB was applied to the scar of the first resection and other suspicious lesions in the bladder. After the second-look, we studied the follow-up of each patient. RESULTS Specimens obtained during the second TURBT showed no tumor in 47 (54,02%) patients; 40 (45,98%) patients had residual cancer: 34 of them had cancer of the same stage, 6 patients of pT1 had a lower stage, and 3 had a higher stage. 5 patient underwent radical cistectomy immediatly after re-TURBT. During the first year of follow up, 15 patients had a recurrent bladder cancer; 2 of them underwent radical cistectomy. CONCLUSIONS T1 bladder cancer is an high risk tumor, so that second-look TURBT is a valuable procedure for accurate staging of nonmuscle-invasive bladder cancer and it can guarantee a better eradication of the neoplasm.

Abstract
The International Collaboration on Cancer Reporting (ICCR) is an alliance of major pathology organisations in Australasia, Canada, Europe, United Kingdom, and United States of America that develops internationally standardised, evidence-based datasets for the pathology reporting of cancer specimens. This dataset was developed by a multidisciplinary panel of international experts based on previously published ICCR guidelines for the production of cancer datasets. It is composed of Required (core) and Recommended (noncore) elements identified on the basis of literature review and expert consensus. The document also includes an explanatory commentary explaining the rationale behind the categorization of individual data items and provides guidance on how these should be collected and reported. The dataset includes nine required and six recommended elements for the reporting of cancers of the urinary tract in biopsy and transurethral resection (TUR) specimens. The required elements include specimen site, operative procedure, histological tumor type, subtype/variant of urothelial carcinoma, tumor grade, extent of invasion, status of muscularis propria, noninvasive carcinoma, and lymphovascular invasion (LVI). The recommended elements include clinical information, block identification key, extent of T1 disease, associated epithelial lesions, coexistent pathology, and ancillary studies. The dataset provides a structured template for globally harmonized collection of pathology data required for management of patients diagnosed with cancer of the urinary tract in biopsy and TUR specimens. It is expected that this will facilitate international collaboration, reduce duplication of effort in updating current national/institutional datasets, and be particularly useful for countries that have not developed their own datasets.

Comparative Application of Different Substaging Techniques for Non-Muscle Invasive Urothelial Carcinoma. Pathol Oncol Res 2019; 26:1823-1831. [PMID: 31754921 DOI: 10.1007/s12253-019-00767-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2019] [Accepted: 10/14/2019] [Indexed: 10/25/2022]
Abstract
To evaluate the diagnostic performance and clinical significance of 4 systems of substaging cases with non-muscle invasive urothelial bladder carcinoma. In addition 4 cutoff measures were evaluated for prediction of muscularis-mucosa invasion. Four substaging systems were applied to 57 NMIBC cases to assess which of these reported methods correlates best with recurrence and progression. On univariate regression analysis patients having tumor size more than 3 cm, solid tumor architecture, high grade, substage B, substage T1e, substage ROL 2 and Tumor depth more than 1 mm were associated with higher recurrence. On multivariate analysis all the four substaging systems, tumor size, grade and tumor type had significant prognostic value for recurrence. Regarding progression only the metric substaging method was associated with tumor progression (p = 0.04). However, on univariate and multivariate regression analysis none of the substaging systems showed prognostic significance and only solid tumor architecture and CIS had significant prognostic value for tumor progression. The ROC curve analysis showed that 1 mm depth of invasion had the best accuracy for detection of muscularis-mucosa invasion (80.2%). Using 1 mm cutoff in measuring the depth and 0.5 mm for the diameter of infiltration may provide clinically relevant information to guide a more personalized therapy for NMIBC. Inclusion of both measures in addition to other histopathologic variables may aid in the development of a scoring system.

Abstract
Purpose To evaluate the prognostic value of substaging on oncological outcomes in patients with T (or pT1) urothelial carcinoma of the bladder. Methods A literature search using PubMed, Scopus, Web of Science, and Cochrane Library was conducted on March 2019 to identify relevant studies according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. The pooled disease recurrence (DR) and disease progression (DP) rate in T1(or pT1) patients were calculated using a fixed or random effects model. Results Overall 36 studies published between 1994 and 2018 including a total of 6781 bladder cancer patients with T1(or pT1) stage were selected for the systematic review and meta-analysis. Twenty-nine studies reported significant association between tumor infiltration depth or muscularis mucosa (MM) invasion and oncological outcomes. Totally 12 studies were included in the meta-analysis. MM invasion (T1a/b/c [or pT1a/b/c] or T1a/b [or pT1a/b] substaging system) was associated with DR (pooled HR: 1.23, 95%CI: 1.01–1.49) and DP (pooled HR: 2.61, 95%CI: 1.61–4.23). Tumor infiltration depth (T1 m/e [or pT1 m/e] substaging system) was also associated with DR (pooled HR: 1.49, 95%CI: 1.11–2.00) and DP (pooled HR: 3.29, 95%CI: 2.39–4.51). Conclusions T1(or pT1) substaging in patients with bladder cancer is of prognostic value as it is associated with oncologic outcomes. Inclusion of this factors into the clinical decision-making process of this heterogeneous tumor may improve outcomes, while avoiding over- and under-treatment for T1(or pT1) bladder cancer.

Abstract
Urothelial carcinoma of the urinary bladder is a heterogeneous disease with multiple possible treatment modalities and a wide spectrum of clinical outcome. Treatment decisions and prognostic expectations hinge on accurate and precise staging, and the recently published American Joint Committee on Cancer (AJCC) Staging Manual, 8th edition, should be the basis for staging of urinary bladder tumours. It is unfortunate that the International Union Against Cancer (UICC) 8th edition failed to incorporate new data which is considered in the AJCC 8th edition. Thus, the AJCC 8th edition is the focus of this review. Several critical changes and clarifications are made by the AJCC 8th edition relative to the 7th edition. Although the most obvious changes in the 8th edition are in the N (i.e. perivesical lymph node involvement now classified as N1) and M (i.e. M1 is subdivided into M1a and M1b) categories, several points are clarified in the T category (e.g. substaging of pT1 should be attempted). Further optimisation, however, is required. No particular method of substaging pT1 is formally recommended. In this review, these modifications are discussed, as well as points, which require further study and optimisation.

Abstract
The aim of the present review was to assess the prognostic impact of lymphovascular invasion (LVI) in transurethral resection (TUR) of bladder cancer (BCa) specimens on clinical outcomes. A systematic review and meta-analysis of the available literature from the past 10 years was performed using MEDLINE, EMBASE and Cochrane library in August 2017. The protocol for this systematic review was registered on PROSPERO (Central Registration Depository: CRD42018084876) and is available in full on the University of York website. Overall, 33 studies (including 6194 patients) evaluating the presence of LVI at TUR were retrieved. LVI was detected in 17.3% of TUR specimens. In 19 studies, including 2941 patients with ≤cT1 stage only, LVI was detected in 15% of specimens. In patients with ≤cT1 stage, LVI at TUR of the bladder tumour (TURBT) was a significant prognostic factor for disease recurrence (pooled hazard ratio [HR] 1.97, 95% CI: 1.47-2.62) and progression (pooled HR 2.95, 95% CI: 2.11-4.13), without heterogeneity (I2 = 0.0%, P = 0.84 and I2 = 0.0%, P = 0.93, respectively). For patients with cT1-2 disease, LVI was significantly associated with upstaging at time of radical cystectomy (pooled odds ratio 2.39, 95% CI: 1.45-3.96), with heterogeneity among studies (I2 = 53.6%, P = 0.044). LVI at TURBT is a robust prognostic factor of disease recurrence and progression in non-muscle invasive BCa. Furthermore, LVI has a strong impact on upstaging in patients with organ-confined disease. The assessment of LVI should be standardized, reported, and considered for inclusion in the TNM classification system, helping clinicians in decision-making and patient counselling.

Abstract
The clinical significance of random bladder biopsies in primary non-muscle-invasive bladder cancer is unclear. The present study investigated the significance of positive random bladder biopsies in primary T1 NMIBC. The present study retrospectively reviewed the records of 71 patients with primary pT1N0M0 bladder cancer who underwent transurethral resection of the bladder tumor (TURBT) and concomitant random bladder biopsy. A total of 12 patients who received cystectomy immediately following the TURBT were excluded, and the remaining 59 patients were included in the analysis. Random bladder biopsy was defined as a cold-cup biopsy of pre-specified normal-looking areas in the bladder. The association of clinicopathological factors, including random biopsy results, with intravesical recurrence were assessed by univariate and multivariate Cox proportional hazards analyses. Of the 59 patients, 15 (25%) demonstrated carcinoma in situ (CIS) lesions on random bladder biopsy: Five (33%) in biopsy specimens alone and the remaining 10 (67%) in biopsy and TUR specimens. Positive random biopsy was associated with preoperative positive urine cytology (P=0.011) and small size of the main tumor (P=0.008). Multivariate analysis demonstrated positive random biopsy as the sole independent poor prognostic factor for intravesical recurrence (hazard ratio: 4.69, P=0.014). The five patients who had CIS detected in biopsy specimens alone had worse, although non-significantly worse, recurrence-free survival compared with those with CIS detected in biopsy and TUR specimens (P=0.100). In conclusion, positive bladder random biopsy, equivalent to the presence of CIS, was an independent predictor of recurrence in primary T1 bladder cancer. Given that one-third of CIS lesions could not have been detected without biopsy, random bladder biopsy should be considered for patients with T1 tumors.

Abstract
CONTEXT Initial treatment for most bladder cancers (BCs) involves transurethral resection (TUR) or tumours. Often more cancer is found after the initial treatment in around half of patients, requiring a second resection. Repeat transurethral resection (reTUR) is recommended for high-risk, non-muscle-invasive bladder cancer (NMIBC) to remove any residual disease and improve cancer outcomes. OBJECTIVE To systematically review the practice and therapeutic benefit of an early reTUR for high-risk NMIBC. EVIDENCE ACQUISITION A systematic review of original articles was performed using PubMed/Medline and Web of Science databases in December 2016 (initial) and October 2017 (final). We searched the references of included papers. EVIDENCE SYNTHESIS We screened 15 209 manuscripts and selected 31 detailing 8409 persons with high-grade Ta and T1BC for inclusion. Detrusor muscle was found at initial TUR histology in 30-100% of cases. Residual tumour at reTUR was found in 17-67% of patients following Ta and in 20-71% following T1 cancer. Most residual tumours (36-86%) were found at the original resection site. Upstaging occurred in 0-8% (Ta to ≥T1) and 0-32% (T1 to ≥T2) of cases. Conflicting data report the impact of reTUR on subsequent recurrence and cancer-specific mortality. Recurrence for Ta was 16% in the reTUR group versus 58% in the non-reTUR group. For T1, recurrence ranged from 18% to 56%, but no clear trend was identified between reTUR and control. No clear relationship between reTUR and progression was found for Ta, although for T1 rates were higher in the non-reTUR group in series with control populations (5/6 studies). Overall mortality was slightly reduced in the reTUR group in two studies with controls (22-30% vs 26-36% [no reTUR]). CONCLUSIONS Residual tumour is common after TUR for high-risk NMIBC. The reTUR helps in the diagnosis of this residual cancer and may improve outcomes for cancers initially staged as T1. PATIENT SUMMARY Some bladder cancers (BCs) are aggressive but confined to the bladder surface. Initial treatment includes endoscopic resection. More cancer is found after the initial treatment in approximately half of patients. In the aggressive but confined group of BC, a second resection, a few weeks after the first, may help find this residual cancer and improve outcomes, although the evidence quality for this is weak.

Abstract
Background Lymphovascular invasion (LVI) in high-grade clinical T1 bladder cancer is usually considered a poor prognostic factor, but it is often difficult to achieve correct staging of T1 bladder cancer and diagnose the presence of LVI because of the inadequacy of conventional transurethral resection specimens. The aims of this study were to evaluate the prognostic value of LVI in patients with correctly staged high-grade pathological T1 (pT1) bladder cancer who initially underwent transurethral resection in one piece (TURBO). Methods Eighty-six high-grade pT1 bladder cancer patients who underwent TURBO were enrolled. Risk of tumor understaging was avoided by examining the vertical resection margin of the TURBO specimen. Immunohistochemical staining using D2-40 and CD31 was performed to confirm LVI. We examined the association of LVI with other clinicopathological factors and the impact of LVI on progression-free survival and cancer-specific survival. Results The median follow-up period was 49 months (range, 6-142). In all patients, the tumors were accurately staged as pT1 at initial TURBO. LVI was detected in 15 patients (17%) and was significantly associated with tumor growth pattern (P = 0.001). Multivariate analysis identified LVI as the only independent predictor for reduced progression-free survival (HR, 4.48; 95% CI, 1.45-13.90; P = 0.009) and cancer-specific survival (HR, 4.35; 95% CI, 1.17-16.24; P = 0.029). Conclusions The presence of LVI in TURBO specimens independently predicts poor clinical outcomes in patients with high-grade pT1 bladder cancer. This information may help urologists to counsel their patients when deciding whether to choose a bladder-preserving strategy or radical cystectomy.

Abstract
Bladder cancer has a high incidence and involves high associated morbidity and mortality. Since its initial clinical suspicion, early diagnostic confirmation and multimodal treatment involve different medical specialties. For this reason, we consider it important to spread the current consensus for its management. Recent advances in immunology and Chemotherapy make it necessary to expose and reflect on future perspectives.

The paradigm of pathologic stage (pT) categorization in bladder cancer remains the depth of invasion into the different histologic layers of the bladder wall. However, the approaches to assigning pT stage category toward an enhanced outcome stratification have been marked by challenges and innovations, due in part to our growing appreciation of the surprisingly perplexing bladder histoanatomy. Upstaging of pT1 tumors after radical cystectomy is substantial and underscores the potential value of pT1 substaging in transurethral resection (TUR) specimens. The 2017 American Joint Committee on Cancer tumor-node-metastasis system recommends pT1 substaging but recognizes the need to optimize the approach. Over the years, the cut-off for microinvasion has been significantly lowered to 0.5 mm and is now a promising scheme for pT1 (micrometric) substaging. Unlike the micrometric approach, histoanatomic substaging using muscularis mucosae (MM) and vascular plexus as landmarks is less feasible in TUR specimens and inconsistent in stratifying the outcome of pT1 tumors. The lamina propria possesses inherent variations in depth, MM, and vascular plexus dispositions that should be factored in future pT1 substaging proposals. Histoanatomic variations among the bladder regions also occur, and studies suggest that trigone and bladder neck cancers may have more adverse outcomes. The muscularis propria (MP), besides being the essential histologic landmark for assigning pT2 stage category, is also considered a surrogate for the adequacy of TUR, furthering the importance of identifying its presence in TUR specimens. MP, however, may be mimicked by hyperplastic or isolated MP-like MM muscle bundles in the lamina propria with overstaging implications, and caution should be exercised in distinguishing these 2 muscle types morphologically and immunohistochemically. Presence of additional superficial MP unique from the detrusor muscle proper may also complicate staging at the trigone and ureter insertion sites. With regard to the depth of MP invasion, large and multicenter studies have reaffirmed the prognostic significance of pT2a/b subcategories. It is revealed that there are at least 3 ways used to demarcate the irregular MP to perivesical soft tissue junction, and use of a common criterion indicates improvement in pT2b/pT3a staging reproducibility. Although studies have shown significantly poorer outcome in pT3b compared with pT3a tumors, this designation has a substantial reliance on the prosector's gross assessment of perivesical soft tissue invasion which if performed incorrectly may lead to staging inaccuracy of pT3 tumors. The 8th edition of the American Joint Committee on Cancer has updated the staging schema for bladder cancers with concomitant prostatic stromal invasion and cancers within bladder diverticula. Because of 2 possible pT designations, prostatic stromal invasion in TUR specimens should not be automatically staged as either pT4a or pT2 (urethral). Recent data support that bladder cancer invading into the seminal vesicle has comparable outcome to pT4b tumors. Interestingly, several studies in pT4a tumors, which are staged based on sex-specific organs, have shown poorer outcome in females than males after radical cystectomy, and while there are possibly several reasons, they may also include anatomic factors. Despite the progress has been made, work remains to be done to inform future bladder cancer pT category definitions and their reproducibility in application and prognostication.

Lymphovascular invasion status at transurethral resection of bladder tumors may predict subsequent poor response of T1 tumors to bacillus Calmette-Guérin. BMC Urol 2016; 16:5.

Abstract
Background Lymphovascular invasion (LVI) is an important step in the process of tumor dissemination and metastasis outside the primary organ, but the relationship between LVI and the prognosis of T1 non-muscle invasive bladder cancer (NMIBC) has not been fully evaluated. Accordingly, the present study was performed to evaluate whether LVI had an impact on the clinical outcome in patients with T1 NMIBC. Methods A total of 116 consecutive patients were diagnosed with T1 NMIBC from 1994 to 2013 at Keio University Hospital. All cases were reviewed by a single uro-pathologist. The prognostic significance of LVI was assessed in relation to recurrence and stage progression. Results The median follow-up period was 53 months. LVI was histologically confirmed in 30 patients (25.9%). There were no significant differences of clinical features between the patients with and without LVI. In T1 patients, univariate analysis demonstrated that LVI positivity was associated with stage progression (p = 0.003), but not with tumor recurrence (p = 0.192). Multivariate analysis confirmed that LVI was independently associated with stage progression (p = 0.006, hazard ratio = 4.00). In 85 patients who received BCG instillation, LVI was independently associated with both tumor recurrence and stage progression (p = 0.036 and 0.024, hazard ratio = 2.19 and 3.76). Conclusions LVI is a strong indicator of an increased risk of recurrence and progression in BCG-treated patients with T1 NMIBC. This information might assist clinicians to develop appropriate management and counseling strategies for these patients.

Abstract
Objective To evaluate the clinical significance of lymphovascular invasion (LVI) on recurrence and progression rates in patients with pT1 urothelial carcinoma of bladder after transurethral resection. Methods This retrospective study was performed with 155 patients with newly diagnosed pT1 urothelial carcinoma of bladder who were treated with transurethral resection of bladder tumor at our institution from January 2006 to January 2010. The presence or absence of LVI was examined by pathologists. Chi-square test was performed to identify the correlations between LVI and other clinical and pathological features. Kaplan–Meier method was used to estimate the recurrence-free survival (RFS) and progression-free survival curves and difference was determined by the log-rank test. Univariate and multivariate analyses were performed to determine the predictive factors through a Cox proportional hazards analysis model. Results LVI was detected in a total of 34 patients (21.9%). While LVI was associated with high-grade tumors (P<0.001) and intravesical therapy (P=0.009). Correlations with age (P=0.227), sex (P=0.376), tumor size (P=0.969), tumor multiplicity (P=0.196), carcinoma in situ (P=0.321), and smoking (P=0.438) were not statistically significant. There was a statistically significant tendency toward higher recurrence rate and shorter RFS time in LVI-positive patients. However, no statistically significant differences were observed in progression rate between the two groups. Moreover, multivariate Cox proportional hazards analysis revealed that LVI, tumor size, and smoking were independent prognostic predictors of recurrence. The hazard ratios (95% confidence interval) were 2.042 (1.113–3.746, P=0.021), 1.817 (1.014–3.256, P=0.045), and 2.079 (1.172–3.687, P=0.012), respectively. Conclusion The presence of LVI in transurethral resection of bladder tumor specimens is significantly associated with higher recurrence rate and shorter RFS time in patients with newly diagnosed T1 urothelial carcinoma of the bladder. It is an independent prognostic predictor for disease recurrence. Thus, patients with LVI should be followed up closely.

Abstract
BACKGROUND Molecular prognostic markers have been under investigation for the last decade and no validated marker to date has been proven to be used in daily clinical practice for urinary bladder cancers. The aim of the present study is to evaluate the significance of HYAL-1 expression in prediction of recurrence and progression in pT1 urothelial carcinomas. MATERIALS AND METHODS Eighty-nine urothelial carcinoma cases staged as T1 according to 2004 WHO classification were studied. Representative sections from every case were stained immunohistochemically for HYAL-1 and scored between 0 and +3, according to staining density, and graded as low and high for the scores 0-1 and 2-3, respectively. RESULTS Of the 89 pT1 bladder cancer patients, HYAL-1 expression was high in 92.1% (82 patients; 72 patients +3 and 10 patients +2) and low in 7.9% (only 7 patients; 6 patients +1 and 1 patient 0) of the cases. Of the 89 patients, 38 (42.7%) had recurrence and 22 (24.7%) showed progression. HYAL-1 staining did not show significant characteristics for tumor grade, accompanying CIS, multiplicity, tumor size, age and sex. HYAL-1 expression did not have any prognostic value in estimating recurrence or progression. CONCLUSIONS HYAL-1 expression was found to be high, but did not have any prognostic importance in T1 bladder urothelial carcinomas.

Abstract
BACKGROUND Urothelial carcinoma (UC) is a malignant neoplasm that most commonly occurs in the urinary bladder. The primary aim of this study was to evaluate the clinicopathologic features, recurrence and progression in patients with bladder urothelial cancer. MATERIALS AND METHODS The medical records of patients diagnosed with UC in the state pathology laboratory between January 2006 and July 2014 were retrospectively included. Carcinomas were categorized according to age, gender, histologic grade, tumor configuration, pathologic staging, recurrence status, and progression. RESULTS A total of 125 (113 men, 12 women) patients were examined. The mean age was 65.9 years and the male-to-female urothelial cancer incidence ratio was 9.4:1. Low-grade UCs were observed in 85 (68%) and high-grade in 40 (32%). A papillary tumor pattern was observed in 67.2% of the UCs. Cases were classified with the following pathological grades: 34 (27.2%) cases of pTa, 70 (56%) of pT1, and 21 (16.8%) of pT2. Recurrence occurred in 27 (21.6%) patients. Ten progressed to a higher stage (pT1 to pT2), and three cases to higher grade (low to high). We also analyzed the results separately for 70 (56%) patients 65 years of age and older. CONCLUSIONS With early detection and diagnosis of precursor lesions in older patients, by methods such as standard urologic evaluation, urinary cytology, ultrasound scanning and contrast urography, and cystoscopy, in addition to coordinated efforts between pathologists and urologists, early diagnosis may reduce the morbidity and mortality of patients with urothelial carcinoma.

Abstract
For non-muscle invasive bladder cancer, a disease with a considerable epidemiological and socio-economic impact, the introduction of the Guidelines has always evoked as a tool for the resolution of long-standing disputes in terms of diagnosis and therapy. Check the degree of routine clinical practice adherence to the Recommendations is for this disease, more than for other uro-oncology pathology, an urgent need felt by the urological community. To assess the level of Guidelines adherence's, and study issues related to the paths of diagnosis and treatment of non-muscle invasive bladder cancer, and identifying the processes actually implemented in daily clinical practice, a series of case studies has submitted to a group of experts. The acknowledgement study allowed testing the impact of the current Evidence Based Medicine Recommendations in the everyday clinical practice identifying strengths and weaknesses. Questions Responses Analysis' of 5 clinical cases (Ta low grade, T1 low grade, T1 high grade, T1 high grade + CIS, Ta low-grade multiple recurrence) showed a moderate amendment to the European Association of Urology (EAU)-Guidelines. On the other hand, it was emphasized that there are clear discrepancies between what should be done, in accordance with the Evidence Based Medicine Recommendations, and what is actually do in everyday clinical practice. The most common reason for the low Recommendations adherences are structural and organizational practical limitations.

Abstract
Most T1 bladder cancers are high grade and have the potential to progress to muscle invasion and extravesical dissemination. Many studies reported that ∼50% of patients displayed residual tumors when a second transurethral resection was performed 2-6 weeks after the initial resection for patients who were diagnosed with T1 bladder cancer. Furthermore, muscle-invasive disease was detected by the second transurethral resection in 10-25% of those patients. Therefore, a second transurethral resection is strongly recommended for patients newly diagnosed with high-grade T1 bladder cancer in various guidelines. T1 bladder cancers are heterogeneous in terms of progression and prognosis after the second transurethral resection. Optimal management and treatment should be considered for patients with T1 bladder cancer based on the pathological findings for the second transurethral resection specimen. If the second transurethral resection reveals residual tumors, aggressive treatments based on the pathological findings should be performed. Conversely, overtreatment with respect to the tumor status should be avoided. Since the evidence of pathological diagnosis at the second transurethral resection is insufficient and many retrospective studies were carried out before the second transurethral resection era, prospective randomized studies should be conducted.

Abstract
This study was conducted to test a new substaging system in a population of patients with stage T1 bladder cancer (BC) at diagnosis and assess its prognostic role in terms of disease progression and disease-specific survival (DSS). Patients with primary stage T1G3 urothelial carcinoma of the bladder were stratified according to the following models: i) T1a [the tumour does not infiltrate the muscularis mucosae-vascular plexus, (MM-VP)]; T1b (the tumour partially infiltrates the MM-VP); and T1c (the tumour infiltrates and invades the MM-VP). ii) T1m (diameter of tumour infiltrating the lamina propria ≤0.5 mm under a high-resolution microscope; and T1e (diameter of tumour infiltrating the lamina propria >0.5 mm). Age, gender, tumour size and multifocality were not found to be of statistical significance. Using the T1a/T1b/T1c system, patients with stage T1a disease exhibited a 5- and 10-year progression rate of 13.3 and 20%, respectively, without reaching statistical significance. Moreover, patients with stage T1a disease exhibited a 5- and 10-year DSS of 93.3 and 73.3%, respectively, which was higher compared to T1b and T1c but not statistically significant. Using the T1m/T1e system, patients with stage T1m disease exhibited a disease progression rate of 8.3 and 16.7% at 5 and 10 years, respectively, which was not statistically significant. Moreover, patients in group T1m presented with DSS rates of 91.7 and 83.3% at 5 and 10 years, respectively, which were higher compared to those in the T1e group (71.4 and 60.7%), although not reaching statistical significance. In conclusion, in our study, neither of the two substaging systems of stage T1 BC reached the prognostic conventional significance level for tumour progression or DSS.

Abstract
OBJECTIVE Carcinoma of the renal pelvis and ureter are unusual tumours and our limited knowledge comes mainly from case reports and small series from large academic hospitals, as a rule without histopathological review. This study reports aetiological and demographical factors as well as clinicopathological findings of all patients in a large geographical region. MATERIAL AND METHODS All patients in western Sweden with a renal pelvic or ureteral tumour diagnosed between 1971 and 1998 (n = 930) were included. Untreated cases were not excluded. Demographic data and results of preoperative examinations were retrieved from the original clinical records. The histopathological slides were reviewed and tumour stage, grade, configuration, presence of carcinoma in situ and angiolymphatic invasion were determined. RESULTS The majority of patients (80%) had invasive or high-grade tumours. Carcinoma in situ was present among 30% of patients with non-invasive high-grade tumours. Angiolymphatic invasion (62%) and solid (non-papillary) growth pattern (84%) were very common among patients with stage T2-T4 tumours. Twenty-three women out of 138 (16.7%) with ureteral carcinoma had a history of abdominal radiotherapy for gynaecological cancer 22 years (median) earlier. Forty-one patients out of 930 (4.4%) had a history of abuse of phenacetin-containing analgesics. CONCLUSIONS This study demonstrates a very high incidence of high-grade upper tract tumours with carcinoma in situ, angiolymphatic invasion and solid (non-papillary) growth pattern, which underscores the malignant character of the disease. The possible association between pelvic radiotherapy and ureteral carcinoma warrants further study.

Abstract
PURPOSE High-grade (HG) stage pT1 bladder cancers have the highest recurrence and progression rates of all non-muscle-invasive bladder cancers. Some prognostic factors for recurrence and progression have been identified: multifocal HG pT1, concomitant carcinome in situ, tumor diameter >3 cm, infiltration of the deep lamina propria, and persistence of pT1 tumor on a second transurethral resection of the bladder. The objective of this study was to determine whether the presence of lymphovascular invasion (LVI) is also a prognostic factor that must be taken into account. MATERIALS AND METHODS This retrospective study was performed with 108 patients with HG stage pT1 bladder cancer: 89 patients were treated conservatively (transurethral resection of the bladder plus bacille Calmette-Guérin therapy), and 19 patients underwent early cystectomy. The mean (SD) follow-up was 47.8 ± 41.2 months. Classic prognostic factors and LVI were analyzed in terms of overall survival, specific survival, recurrence-free survival, and progression-free survival. RESULTS Thirty-six percent of patients had LVI on the chips of the first transurethral resection of the bladder. Five-year overall survival and specific survival were 40% and 75%, respectively. Multivariate analysis of risk factors showed a significant reduction of overall survival in the presence of LVI (P = .007). The presence of LVI was also a factor of poor prognosis in the case of delayed cystectomy (P = .010) but not in the case of early cystectomy. CONCLUSIONS Identification of LVI on the first resection of a HG stage pT1 bladder cancer is a significant prognostic factor for overall survival.

Abstract
PURPOSE OF REVIEW As high-risk nonmuscle invasive bladder cancer (NMIBC) has a high propensity to recur and progress, the primary therapeutic goal in patients with high-risk NMIBC is the prevention or delay of disease recurrence and progression. RECENT FINDINGS For improving transurethral resection quality, new optical enhancement technology such as optical coherence tomography, photodynamic diagnosis and narrow band imaging might be considered because these emerging optical techniques may contribute to resection completeness and reduce the recurrence risk. Recent studies have confirmed that a second resection is associated with a lower risk of progression and cancer-related death. Although maintenance bacillus Calmette-Guérin (BCG) for at least 1 year has been recommended, some studies have shown no significant advantage to maintenance BCG. Although other options may be considered in early BCG failure, there are no large trials that have shown a long-term benefit in BCG-failure patients. SUMMARY Current literature suggests that the best treatment for patients with high-risk NMIBC involves complete transurethral resection with intravesical BCG therapy. New approaches or therapeutic agents for preventing recurrence and progression are needed in this field.

Abstract
Providing the best management for patients with bladder cancer relies on close cooperation among uro-oncologists and pathologists. The pathologist is involved in the diagnosis and assessment of prognostic and therapeutic factors in bladder biopsies, transurethral resection (TUR) and cystectomy specimens. The pathologist must report accurately the key features using terms that are well understood by clinicians. Adequate clinical information is important to pathologists in deciding the best approach in handling and processing the surgical specimens.

Korean J Urol 2012; 53:317-23.

Abstract
Purpose To evaluate the prognostic significance of the depth of lamina propria invasion in primary T1 transitional cell carcinoma (TCC) of the bladder. Materials and Methods We retrospectively reviewed the medical records of 183 patients with primary T1 TCC of the bladder who had undergone transurethral resection (TUR) at our institution. Substaging was defined according to the depth of lamina propria invasion as follows: T1a, superficial invasion of lamina propria; T1b, invasion into the muscularis mucosa (MM); T1c, invasion beyond the MM but not to the muscularis propria. The prognostic significance of various clinicopathological variables for recurrence and progression was analyzed. Results Of the 183 patients, substaging was T1a in 119, T1b in 57, and T1c in 7 patients. The recurrence rate was 32.8% for T1a and 40.6% for T1b/c, but there was no significant difference between the two groups. The progression rate was significantly different between the two groups: 5.8% in T1a and 21.9% in T1b/c (p=0.003). The cancer-specific mortality rate was also significantly different: 4.2% in T1a and 14.0% in T1b/c (p=0.036). In the univariate analysis, microscopic tumor architecture was the only significant prognostic factor for recurrence. In the univariate and multivariate analysis concerning progression, depth of lamina propria invasion and concomitant carcinoma in situ were significant prognostic factors. Conclusions Substaging according to the depth of lamina propria invasion in primary T1 TCC of the bladder was an independent prognostic factor for progression. This suggests that substaging would be helpful for guiding decisions about adjuvant therapies and follow-up strategies.

Abstract
T1 high-grade (formerly T1G3) bladder cancer is a challenging clinical entity representing approximately 10-15% of all new bladder cancer cases. The variable natural history of the disease and possible impairment in quality of life associated with radical treatment makes T1 high-grade one of the most challenging uro-oncological patient groups to manage. In particular, the risk of clinical understaging and not recognizing muscle-invasive disease may have detrimental effects on patient outcome. The cornerstone of contemporary staging is restaging transurethral resection (TUR), which helps in defining further management. In patients with restaging TUR stage less than T1, induction bacillus Calmette-Guérin combined with maintenance offers good results. The option of radical cystectomy should be discussed with patients with restaging TUR stage T1 or higher and it is highly recommended to all patients with recurrent T1 of carcinoma in situ during bacillus Calmette-Guérin maintenance. In addition to restaging TUR stage, several other clinicopathological factors, such T1 substaging, associated carcinoma in situ, tumor size and appearance, lymphovascular invasion, and hydronephrosis, aid in the decision making between radical and conservative treatment. Future prospects include improved staging and molecular markers that may guide toward conservative therapy or allow more cT1 patients to be offered nerve-sparing cystectomies and neobladders and, thus, improving quality of life for patients undergoing radical surgery.

Abstract
PURPOSE AND METHODS Patients with nodal negative colorectal cancer (CRC) suffer recurrent or metastatic disease in 40% of cases after surgical resection. To investigate a potential prognostic impact of vascular tumor infiltration, we retrospectively analyzed 185 nodal negative stage I and II CRC specimens for the presence of intra- and/or extramural venous invasion (V1IM/V1EM) using elastic stains of all tumor sections and correlated our findings with the clinical follow-up. RESULTS Venous invasion was observed in 43 (23.2%) patients by elastic stains compared with six (3.2%) using HE only (p < 0.05). Venous invasion was more common in stage II than in stage I tumors (28.1% versus 5.1%; p < 0.05). However, survival analyses showed no significant differences in 5-year survival rates comparing patients with and without venous invasion (68% and 71%, p = 0.543) or patients with V1IM and V1EM (62% vs. 74%, p = 0.473), respectively. CONCLUSIONS Our data emphasize the need for standardized criteria, including elastic stains, to reliably detect vascular invasion in CRC. Doing so, however, the prognostic impact of venous invasion in stage I and II CRC may be lower as previously anticipated.
