Abstract
OBJECTIVE To evaluate the prognostic value of T1 substaging in patients treated with bacillus Calmette-Guérin (BCG) or immediate radical cystectomy (iRC). MATERIALS AND METHODS We performed an institutional review board-approved retrospective study analysing non-muscle-invasive bladder cancer (NMIBC) patients with pT1 disease treated with either BCG or iRC between 2000 and 2020. Lamina propria (LP) invasion characteristics were extracted from the pathology report. The Kaplan-Meier method was used to calculate overall survival (OS), cancer-specific survival (CSS) and metastasis-free survival (MFS). Multivariable Cox models were used to determine the association between progression-free survival (PFS) and characteristics in the BCG cohort. A logistic regression model explored the relationship between T1 substaging and upstaging to >pT2 at iRC. RESULTS A total of 411 T1 high-grade patients were identified. LP invasion characteristics were as follows: not specified: 115 (28%); focal/superficial (F/S): 147 (35.8%); and extensive/multifocal (E/M): 149 (36.2%). Overall, 303 patients (73.7%) received BCG, and 108 patients (26.3%) underwent iRC. The median (interquartile range) follow-up was 53 (32-96) months. Patients with E/M LP invasion were significantly more likely to undergo iRC (34% vs. 19%; P = 0.003). Patients with E/M LP invasion showed poorer MFS and CSS compared to those with F/S LP invasion when treated with BCG but not when treated with iRC. Among BCG-treated patients, progression occurred in 41 patients and E/M LP invasion was independently associated with progression after BCG (hazard ratio 5.3, 95% confidence interval [CI] 2.2-13.1; P < 0.001). T1 substaging was not associated with upstaging at RC (odds ratio 3.15, 95% CI 0.82-12.12; P = 0.095). CONCLUSIONS Extensive/multifocal LP invasion was associated with poor PFS, MFS and CSS in patients treated with BCG. T1 substaging provides valuable prognostic information and should be reported in pathology reports.

Abstract
INTRODUCTION Bladder cancer is among the most common malignant neoplasms in the world. Transurethral resection of bladder tumor (TURBT) is considered the standard procedure for diagnosis, staging, and risk classification of bladder tumors. Lymphovascular invasion (LVI) is considered a poor prognostic factor. Its assessment of TURBT is very important for risk stratification and decision-making for further treatment. The purpose of our clinical study is to attempt to predict/assess the correlation between LVI and various preoperative (age, gender, history of smoking, hematuria, urine cytology, and hydronephrosis/hydroureteronephrosis), intraoperative (tumor number, size, and appearance - sessile/ pedunculated) and histopathological (tumor histology, grading, and muscle invasion) factors. METHODOLOGY In this prospective study, 75 patients with bladder tumors underwent TURBT (standard monopolar TURBT with 1.5% glycine as irrigation solution) in the Department of Urology at Sri Venkateswara Institute of Medical Sciences (SVIMS), Tirupati between October 2021 and March 2023. Histopathological examination (HPE) reports were looked for the presence or absence of LVI. Accordingly, patients were divided into two groups, i.e., those with LVI and those without LVI. Various preoperative and intraoperative variables were analyzed for each subject in both groups. Statistically significant variables occurring in those patients with LVI compared to those without LVI were considered predictors of LVI in bladder tumors. Results: Sixteen patients out of 75 (21.33%) had LVI on their histopathology examination. The mean age was 68.19 years in the group with LVI and 64.14 years in the group without LVI. A total of 60 men (80%) and 15 women (20%) were included in our study. Thirteen men (21.7%) and three women (20%) were found to have LVI. We observed a significant association between the appearance of the tumor and LVI. Fifty-four subjects in our study had sessile tumors. Fifteen out of them (27.8%) had LVI, while only one out of 21 patients (4.8%) with pedunculated tumors had LVI (p-value=0.028). 30% of subjects who had high-grade tumors on HPE also had LVI. On the contrary, only one of 25 patients (4%) with low-grade tumors had LVI (p-value=0.010). Our study also showed a significant association between muscle invasion and LVI. Thirty-four (45.3%) and 41 (54.7%) patients had muscle-invasive and non-muscle-invasive tumors, respectively. While 12 (35.3%) patients with muscle-invasive tumors had LVI, only four (9.8%) patients with non-muscle-invasive tumors showed LVI (p-value=0.007). CONCLUSION We observed that LVI of bladder tumors at first TURBT is significantly associated with tumor grade, tumor appearance, and depth of invasion of the tumor. Though statistically not significant, we further observed that LVI was more commonly found in smokers, patients with hematuria, and larger tumor sizes. We conclude that these factors can be used as reliable predictors of LVI of bladder tumors at their first TURBT.

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
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.

Abstract
PURPOSE This study sought to identify factors associated with survival of pT1 urothelial carcinoma of bladder (UCB) after radical cystectomy (RC). METHODS This study consists of 114 pT1 UCB [primary 83, recurrent 31, none were amenable to transurethral resection (TUR)] treated by radical cystectomy. Survival analysis using Cox regression tests were performed to identify factors associated with survival of pT1 UCB after RC. RESULTS Pelvic lymph node (LN) status, age and lymphovascular invasion (LVI) are associated with survival of pT1 UCB after RC; recurrent pT1 UCB of high grade origin (HGO) tends to have poorer CSS than primary pT1 UCB or recurrent pT1 UCB of low grade origin (LGO) (5-year and 10-year CSS rates was 75% and 73% for primary cases; 77% and 77% for recurrent pT1 UCB of LGO; and 56% and 37% for recurrent pT1 UCB of HGO, p = 0.078). CONCLUSIONS LN status, age and LVI were significantly associated with survival of pT1 UCB after RC. Recurrent pT1 UCB of HGO should be managed with radical cystectomy in a timely fashion given that these cases tend to have poorer CSS than primary pT1 UCB after RC, even if they did not progress to muscle-invasive bladder cancer (MIBC).

Abstract
Tumor follow-up in patients with non-muscle invasive bladder cancer (NMIBC) is a weighing up between the morbidity associated with invasive diagnostics and the risk of tumor recurrence and especially progression. The risk stratification into low, intermediate, and high-risk tumors enables a risk-adapted follow-up. For individual estimation of the risk of progression and recurrence, risk calculators should be used. Follow-up is still based on cystoscopy, which is recommended lifelong for high and intermediate-risk tumors and for up to 5 tumor-free years for low-risk tumors. Urine cytology has a high sensitivity and specificity for high-risk tumors and is recommended in the follow-up care. There is currently no recommendation for any commercially available urinary marker due to inadequate evidence. For the clarification of synchronous and metachronous tumors of the upper urinary tract computed tomography (CT) urography or alternatively magnetic resonance (MR) urography is recommended.

Abstract
PURPOSE OF REVIEW A bladder-preserving approach for high-grade nonmuscle invasive bladder cancer that has invaded the lamina propria (T1HG) may result in increased recurrence, progression, and even death from bladder cancer in some patients. Initial radical cystectomy does have increased cancer-specific survival (CSS), but represents significant overtreatment for many patients. An evidence-based, risk-stratified approach is required to select patients for immediate radical cystectomy in order to improve CSS. RECENT FINDINGS A restaging transurethral resection aids in optimal staging and treatment of T1HG. Intravesical Bacillus Calmette-Guerin induction followed by 3 years of maintenance is the standard adjuvant management. However, when very high-risk (hydronephrosis, abnormal bimanual examination, variant histology, lymphovascular invasion, or residual disease on re-resection, and Bacillus Calmette-Guerin failure or early recurrence) or multiple high-risk factors (concomitant CIS, size >3 cm, multifocality, unfavorable tumor location, extensive lamina propria invasion, and elderly) are present, the risk of progression often outweighs the risk associated with radical cystectomy. In these cases, an immediate radical cystectomy likely provides an improved opportunity for cure compared to a bladder-preserving strategy. SUMMARY In order to increase the CSS of patients diagnosed with T1HG bladder cancer, an aggressive approach may benefit those with increased risk of progression.

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.

Jpn J Clin Oncol 2017; 47:447-452.

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
Outcome prediction in patients with bladder cancer has improved through the development of nomograms and predictive models. However, integration of further characteristics such as lymphovascular invasion (LVI) might increase the accuracy and clinical utility of these instruments. Assessment and reporting of LVI in specimens from transurethral resection of the bladder tumour (TURBT) or biopsy in patients with non-muscle-invasive bladder cancer (NMIBC) or muscle-invasive bladder cancer (MIBC) might enable improved staging, prognostication and clinical decision-making. In NMIBC, presence of LVI in TURBT and biopsy samples seems to be associated with understaging and increased risks of disease recurrence and progression. In MIBC, presence of LVI is associated with features of aggressive disease and predicts recurrence and survival. Integration of LVI status into predictive models might aid clinical decision-making regarding intravesical instillation schedules and regimens, early radical cystectomy in patients with high-grade T1 disease and perioperative chemotherapy. However, LVI assessment is hampered by insufficient reproducibility and reliability, lack of routine evaluation and limited concordance between findings in TURBT and radical cystectomy specimens. Standardization of the pathological criteria defining LVI is warranted to improve its reporting in routine clinical practice and its utility as a care-changing prognostic marker.

Abstract
PURPOSE OF REVIEW To summarize clinical management of nonmuscle-invasive bladder cancer (NMIBC) and discuss recent advances in the field. RECENT FINDINGS NMIBC remains a common and expensive clinical entity. Prevention, early detection, and risk-adapted treatment are the mainstays of clinical management, all of which may improve as a result of recent research. Photodynamic diagnosis has demonstrated improved detection of nascent disease, and specific clinical scenarios have been identified in which photodynamic diagnosis may improve clinical outcomes. New intravesical chemotherapeutic and immunotherapeutic agents challenge our current paradigm for intermediate/high-risk NMIBC and may delay need for cystectomy after bacillus Calmette-Guerin failure. Progress in risk stratification increasingly permits individualized management regimens for NMIBC. SUMMARY NMIBC includes many heterogeneous disease states with a variety of clinical behaviors that may evolve over time. Improved detection and risk stratification promise assignment of the optimal treatment option for an individual patient at a given time.

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
Bladder cancer remains a commonly diagnosed malignancy worldwide, bringing huge economic burden and high morbidity for patients. Assessment of prognostic significance of lymphovascular invasion (LVI) is a critical issue in the surgical management of bladder cancer after transurethral resection or radical cystectomy. A systematic search of PubMed, Embase and Cochrane Library was performed up to Oct 10, 2014 to identify eligible studies. Outcomes of interest were collected from studies comparing overall survival (OS), cancer specific survival (CSS) and recurrence free survival (RFS) in patients with the LVI. Results of studies were pooled, and combined hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) for survival were used as the effect size estimation. Funnel plots were done to show the publication bias, while the forest plots and subgroup analyses were used to limit the heterogeneity. A total of 20 studies (10 663 patients) met the eligibility criteria and were included for this meta-analysis. Our pooled results showed that there were significant differences in OS (pooled HR, 1.71; 95%CI, 1.52-1.92; P<0.00001), CSS (pooled HR, 2.25; 95% CI, 1.80-2.81; P<0.00001) and RFS (pooled HR, 1.91; 95% CI, 1.57-2.32; P<0.00001) between the patients with LVI and the patients without LVI. There were significant heterogeneities observed in the studies concerning the relationship between LVI and CSS, RFS. There was no clear evidence of publication bias. When tumor stage was beyond T3, LVI lost its predictive value for CSS and RFS. For the patients who had negative lymph nodes, LVI was still an adverse predictor. Our pooled results demonstrate that LVI indicates poor prognosis of patients with bladder cancer after surgical procedures, and it can be of particular importance in clinical practice. However, these results need to be further confirmed by more adequately designed prospective studies.

Abstract
T1 bladder cancer constitutes approximately 25% of incident bladder cancers, and as such carries an important public health impact. Notably, it has a heterogeneous natural history, with large variation in reported oncologic outcomes. Optimal risk-stratification is essential to individualize patient management, targeting those at greatest risk of progression for aggressive therapies such as early cystectomy, while allowing others to safely pursue bladder-preserving approaches including intravesical bacillus Calmette-Guerrin (BCG). Current strategies for diagnosis, risk-stratification, and treatment are imperfect, but emerging technologies and molecular approaches represent exciting opportunities to advance clinical paradigms in management of this disease entity.

Clinical and therapeutic factors associated with adverse pathological outcomes in clinically node-negative patients treated with neoadjuvant cisplatin-based chemotherapy and radical cystectomy. World J Urol 2015; 34:695-701. [PMID: 26286880 DOI: 10.1007/s00345-015-1667-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2015] [Accepted: 08/07/2015] [Indexed: 10/23/2022] Open
Abstract
PURPOSE Several disease characteristics have been identified as potential predictors for pathological node involvement (pN+) following radical cystectomy (RC). However, these have not been assessed in patients treated with neoadjuvant chemotherapy (NAC). We endeavored to assess factors predicting adverse pathology in clinically node-negative patients treated with NAC and RC. METHODS Patients from four North American institutions with cT2-4aN0M0 UC who received three or four cycles of NAC followed by RC were selected. Logistic regression was used to predict pN+, <pT2 and pT4 disease. RESULTS One hundred and ninety-six patients were included. The clinical stage was cT2 in 115 (61 %), cT3 in 62 (33 %) and cT4 in 12 (6 %) cases. NAC regiments were gemcitabine-cisplatin (GC)-4 cycles 57 (29 %), GC-3 cycles 77 (39 %), methotrexate, vinblastine, adriamycin, cisplatin (MVAC)-3 cycle 22 (11 %) and MVAC-4 cycles 40 (21 %). pN+ was seen in 35 (18 %) patients. In the logistic regression analysis, cT4 stage (OR 7.50; 95 % CI 1.58-33.3) and three compared to four cycles of GC (OR 3.44; 95 % CI 1.09-10.9) were significant predictors of pN+ status. Additionally, when controlling for clinical stage, three cycles of GC, compared to four, were significantly associated with higher rates of pT4 disease and lower rates of downstaging to non-muscle-invasive disease. CONCLUSIONS The results suggest that four cycles of neoadjuvant GC may be superior to three cycles, and the latter regimen may be associated with adverse pathological findings. Although this would require validation in a prospective trial, it does encourage the completion of the conventional four cycles GC whenever possible.

Abstract
OBJECTIVES To investigate the association between lymphovascular invasion (LVI) and clinical outcome in organ-confined, node-negative urothelial cancer of the bladder (UCB) in a post hoc analysis of a prospective clinical trial. To explore the effect of adjuvant chemotherapy with methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) on outcome in the subset of patients whose tumours exhibited LVI. PATIENTS AND METHODS Surgical and tumour factors were extracted from the operative and pathology reports of 499 patients who had undergone radical cystectomy (RC) for pT1-T2 N0 UCB in the p53-MVAC trial (Southwest Oncology Group 4B951/NCT00005047). The presence or absence of LVI was determined by pathological examination of transurethral resection or RC specimens. Variables were examined in univariate and multivariate Cox proportional hazards models for associations with time to recurrence (TTR) and overall survival (OS). RESULTS Among 499 patients with a median follow-up of 4.9 years, a subset of 102 (20%) had LVI-positive tumours. Of these, 34 patients had pT1 and 68 had pT2 disease. LVI was significantly associated with TTR with a hazard ratio (HR) of 1.78 [95% confidence interval (CI) 1.15-2.77; number of events (EV) 95; P = 0.01) and with OS with a HR of 2.02 (95% CI 1.31-3.11; EV 98; P = 0.001) after adjustment for pathological stage. Among 27 patients with LVI-positive tumours who were randomised to receive adjuvant chemotherapy, receiving MVAC was not significantly associated with TTR (HR 0.70, 95% CI 0.16-3.17; EV 7; P = 0.65) or with OS (HR 0.45, 95% CI 0.11-1.83; EV 9; P = 0.26). CONCLUSIONS Our post hoc analysis of the p53-MVAC trial revealed an association between LVI and shorter TTR and OS in patients with pT1-T2N0 disease. The analysis did not show a statistically significant benefit of adjuvant MVAC chemotherapy in patients with LVI, although a possible benefit was not excluded.

Abstract
Background ERG, a member of the ETS family of transcription factors, is a highly specific endothelial marker. We investigated whether the use of ERG immunostaining can help pathologists detect lymphovascular invasion (LVI) and decrease interobserver variability in LVI diagnosis. Methods Fifteen cases of surgically resected colorectal cancers with hepatic metastasis were selected and the most representative sections for LVI detection were immunostained with ERG, CD31, and D2-40. Eight pathologists independently evaluated LVI status on hematoxylin and eosin (H&E) and the corresponding immunostained sections and then convened for a consensus meeting. The results were analyzed by kappa (κ) statistics. Results The average rate of LVI positivity was observed in 43% with H&E only, 10% with CD31, 29% with D2-40, and 16% with ERG. Agreement among pathologists was fair for H&E only (κ=0.27), D2-40 (κ=0.21), ERG (κ=0.23), and was moderate for CD31 (κ=0.55). Consensus revealed that ERG nuclear immunoreactivity showed better visual contrast of LVI detection than the other staining, with improved agreement and LVI detection rate (κ=0.65, LVI positivity rate 80%). Conclusions The present study demonstrated a superiority with ERG immunostaining and indicated that ERG is a promising panendothelial marker that might help pathologists increase LVI detection and decrease interobserver variability in LVI diagnosis.
