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.

Prognosis of Primary Papillary Ta Grade 3 Bladder Cancer in the Non-muscle-invasive Spectrum. Eur Urol Oncol 2023; 6:214-221. [PMID: 36670042 DOI: 10.1016/j.euo.2023.01.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 12/05/2022] [Accepted: 01/02/2023] [Indexed: 01/20/2023]
Abstract
BACKGROUND Ta grade 3 (G3) non-muscle-invasive bladder cancer (NMIBC) is a relatively rare diagnosis with an ambiguous character owing to the presence of an aggressive G3 component together with the lower malignant potential of the Ta component. The European Association of Urology (EAU) NMIBC guidelines recently changed the risk stratification for Ta G3 from high risk to intermediate, high, or very high risk. However, prognostic studies on Ta G3 carcinomas are limited and inconclusive. OBJECTIVE To evaluate the prognostic value of categorizing Ta G3 compared to Ta G2 and T1 G3 carcinomas. DESIGN, SETTING, AND PARTICIPANTS Individual patient data for 5170 primary Ta-T1 bladder tumors from 17 hospitals were analyzed. Transurethral resection of the tumor was performed between 1990 and 2018. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Time to recurrence and time to progression were analyzed using cumulative incidence functions, log-rank tests, and multivariable Cox-regression models with interaction terms stratified by institution. RESULTS AND LIMITATIONS Ta G3 represented 7.5% (387/5170) of Ta-T1 carcinomas of which 42% were classified as intermediate risk. Time to recurrence did not differ between Ta G3 and Ta G2 (p = 0.9) or T1 G3 (p = 0.4). Progression at 5 yr occurred for 3.6% (95% confidence interval [CI] 2.7-4.8%) of Ta G2, 13% (95% CI 9.3-17%) of Ta G3, and 20% (95% CI 17-23%) of T1 G3 carcinomas. Time to progression for Ta G3 was shorter than for Ta G2 (p < 0.001) and longer than for T1 G3 (p = 0.002). Patients with Ta G3 NMIBC with concomitant carcinoma in situ (CIS) had worse prognosis and a similar time to progression as for patients with T1 G3 NMIBC with CIS (p = 0.5). Multivariable analyses for recurrence and progression showed similar results. CONCLUSIONS The prognosis of Ta G3 tumors in terms of progression appears to be in between that of Ta G2 and T1 G3. However, patients with Ta G3 NMIBC with concomitant CIS have worse prognosis that is comparable to that of T1 G3 with CIS. Our results support the recent EAU NMIBC guideline changes for more refined risk stratification of Ta G3 tumors because many of these patients have better prognosis than previously thought. PATIENT SUMMARY We used data from 17 centers in Europe and Canada to assess the prognosis for patients with stage Ta grade 3 (G3) non-muscle-invasive bladder cancer (NMIBC). Time to cancer progression for Ta G3 cancer differed from both Ta G2 and T1 G3 tumors. Our results support the recent change in the European Association of Urology guidelines for more refined risk stratification of Ta G3 NMIBC because many patients with this tumor have better prognosis than previously thought.

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
INTRODUCTION We sought to evaluate the contemporary role of a pathology review on management implications of patients with bladder cancer. METHODS A total of 98 consecutive specimens from transurethral resections in patients with suspected bladder tumours were reviewed at our institution by genitourinary pathologist. Patients were classified into risk groups according to pathology reports obtained before and after review. A management course was proposed according to local institutional practice patterns and main urological guidelines. RESULTS Overall, 34.7% of pathological reviews had significant changes associated with management implications, the majority of which were due to changes in risk category (and/or stage). On review pathology, 12 patients were recommended radical cystectomy instead of conservative management and two patients avoided radical cystectomy. Six patients initially staged as T1 and whose staging did not change after review had a proposed change in management in the form of early cystectomy as a treatment option, as they were deemed very high-risk secondary to high-risk features (such as carcinoma in situ or lymphovascular invasion found on review). Ten patients initially staged as T2 demonstrated high-risk features on review. CONCLUSIONS Review by genitourinary pathologist remains important, as it defines more clearly the tumour risk category and influences the management of T1-T2 bladder cancer patients. A complete initial pathological report has the potential to further decrease the discrepancy between initial and review reports.

Abstract
OBJECTIVES Using data from former reports, this study reviews and analyzes the outcomes of tumor recurrence, tumor progression, and tumor-specific survival of patients with stage Ta bladder tumors. METHODS Data were collected from 19 longitudinal studies of outcomes after the first diagnosis of tumor and collected as individual patient results, that is, as failure times from the first tumor to any of the three outcomes. Altogether, there were 14,252 patients, including 4,050 for the outcome of tumor recurrence, 2,937 for the outcome of tumor progression, and 11,595 for the outcome of disease-specific survival (some patients were available for more than one outcome). RESULTS In these data, the mean time to additional tumors was 7.8 years, the mean time to an invasive tumor was 19.5 years, and the mean tumor-specific survival time was 27.2 years. All three outcomes were significantly related to the 2004 World Health Organization (WHO) tumor grades. CONCLUSIONS Although greater than 50% of those with stage Ta bladder tumors have additional bladder tumors, approximately 80% appear to follow a benign course without developing invasive tumors or dying of bladder cancer. The 2004 WHO grading scheme accounts for some but not all of the prognostic information.

Abstract
Fibroblast growth factors (FGFs) orchestrate a variety of cellular functions by binding to their transmembrane tyrosine-kinase receptors (FGFRs) and activating downstream signalling pathways, including RAS/MAPK, PLCγ1, PI3K, and STATs. In the last ten years, it has become clear that FGF signalling is altered in a high proportion of bladder tumours. Activating mutations and/or overexpression of FGFR3 are common in urothelial tumours with low malignant potential and low-stage and -grade urothelial carcinomas (UCs) and are associated with a lower risk of progression and better survival in some subgroups. FGFR1 is not mutated in UC, but overexpression is frequent in all grades and stages and recent data indicate a role in urothelial epithelial-mesenchymal transition. In vitro and in vivo studies have shown that FGFR inhibition has cytotoxic and/or cytostatic effects in FGFR-dependent bladder cancer cells and FGFR-targeted agents are currently being investigated in clinical studies for the treatment of UC. Urine-based tests detecting common FGFR3 mutations are also under development for surveillance of low-grade and -stage tumours and for general population screening. Overall, FGFRs hold promise as therapeutic targets, diagnostic and prognostic markers, and screening tools for early detection and clinical management of UC.

Abstract
Bladder cancer comprises a heterogeneous group of tumors, the majority of which are non-muscle-invasive bladder cancer (NMIBC) at initial presentation. Low-risk bladder cancer--defined as pTa low-grade papillary tumors--is the type of NMIBC with the most favorable oncologic outcome. Although the risk of progression is less than 1% in 5 years, almost 15% will recur after 1 year, and 32% after 5 years. A complete transurethral resection, followed by an immediate single postoperative instillation of chemotherapy will reduce the risk of recurrence for the first 2 years. Follow-up cystoscopy is required to detect recurrence; in the vast majority of cases the recurrent tumor is of the same stage and grade as the primary tumor. The first follow-up visit, 3 months after surgery, is the most important in predicting risk of recurrence for the future. Recent developments in profiling urine and cancer tissue make it possible to better predict risk of progression and recurrence. In the future this profiling will play an important role in the timing and the choice of treatment, as well as guiding follow-up procedures.

Abstract
Principally there are two different types of bladder cancer. Non-invasive papillary low grade tumors (pTa G1-G2) are genetically stable, recur frequently but show a low risk of progression. On the other hand there are high grade tumors (pT1-4, carcinoma in situ), which are genetically unstable, show biologically aggressive behaviour and progress. The distinction between non-invasive (pTa) and minimal-invasive (pT1) is one of the most challenging areas in bladder pathology. Due to the lack of appropriate auxiliary analysis the diagnosis is based entirely on histopathology. P53 immunohistochemistry can be helpful in the assessment of recurring high grade neoplasia. Targeted therapy in bladder cancer is particularly interesting, since a high number of oncogenes are activated and overexpressed (e.g. HER2 and EGFR).

Abstract
Objectives To study the results of chemotherapy combined with intravesical hyperthermia in patients with mainly BCG-failing carcinoma in situ (CIS). Methods Patients with histologically confirmed CIS were included retrospectively. Outpatient thermochemotherapy treatment was done with mitomycin-C (MMC) and the Synergo® system SB-TS 101 (temperature range between 41 and 44°C), weekly for 6–8 weeks, followed by 4–6 sessions every 6–8 weeks. Results Fifty-one patients were treated between 1997 and 2005 from 15 European centers. Thirty-four were pre-treated with BCG. Mean age was 69.9 years. Twenty-four patients had concomitant papillary tumors. The mean number of hyperthermia/MMC treatments per patient was 10.0. Of the 49 evaluable patients 45 had a biopsy and cytology proven complete response. In two patients CIS disappeared, but they had persistent papillary tumors. Follow-up of 45 complete responders showed 22 recurrences after a mean of 27 months (median 22): T2 (4), T1 (4), T1/CIS (1), CIS (5), Ta/CIS (2), Ta (5) and Tx (1). Side effects (bladder complaints) were generally mild and transient. Conclusions In patients with primary or BCG-failing CIS, treatment with intravesical hyperthermia and MMC appears a safe and effective treatment. The initial complete response rate is 92%, which remains approximately 50% after 2 years.

Abstract
OBJECTIVES To determine the biological behaviour of very large superficial bladder tumours (pTa, pT1) and evaluate the impact of the initial tumour weight on long-term prognosis. MATERIAL AND METHODS Of 1569 patients who presented with bladder tumours over a 10-year period, 1070 of the tumours were superficial. Fifty-nine patients had very large tumours (resected weight >or= 15 g). Case notes were analysed to determine recurrence, progression and survival. Median follow-up was 60 months (range 1-156 months). Histological slides were reviewed for all tumours initially reported as pT1 to determine the presence of uninvolved muscle. Statistical analysis was performed using the Kaplan-Meier method to calculate progression and survival estimates. RESULTS The overall progression and recurrence rates for very large superficial bladder tumours were 18% and 68%, respectively. The progression rates for Ta, T1, G1, G2 and G3 tumours were 4%, 28%, 0%, 20% and 50%, respectively, with highest progression rates being seen for pT1G2 and pT1G3 tumours. The progression rate was significantly influenced by initial stage (p=0.01) and grade (p=0.03). Tumour weight did not affect either recurrence, progression or cause-specific survival. There were no differences in progression and survival rates in patients with tumour weights of 15-30 and >30 g (p=0.80 and 0.07, respectively). The review of histology slides of T1 tumours showed that 7/10 cases (70%) with progression had no muscle or an inadequate amount of muscle for definitive staging. Upper urinary tract tumours were seen in only two patients (3.4%). CONCLUSIONS Large size is not an adverse prognostic factor for patients with a superficial bladder tumour. However, these cases are difficult to stage. In view of the high rates of progression and disease-specific mortality, we recommend that very large pT1G2 bladder tumours should be considered as high-risk tumours and targeted for aggressive treatment, including early re-resection, to rule out any occult invasive disease.

Abstract
We developed nomograms to predict disease recurrence in patients with Ta, T1 transitional cell carcinoma of the bladder. Thirty-eight training hospitals participated in this retrospective multicenter study. Between 1998 and 2002, a total of 1,587 patients with newly diagnosed non-muscle invasive bladder cancer were enrolled in this study. Patients with prior histories of bladder cancer, non-transitional cell carcinoma, or a follow-up duration of less than 12 months were excluded. With univariate and multivariate logistic regression analyses, we constructed nomograms to predict disease recurrence, and internal validation was performed using statistical techniques. Three-year and five-year recurrence-free rates were 64.3% and 55.3%, respectively. Multivariate analysis revealed that age (hazard ratio [HR]=1.437, p<0.001), tumor size (HR=1.328, p=0.001), multiplicity (HR=1.505, p<0.001), tumor grade (HR=1.347, p=0.007), concomitant carcinoma in situ (HR=1.611, p=0.007), and intravesical therapy (HR=0.681, p<0.001) were independent predictors for disease recurrence. Based on these prognostic factors, nomograms for the prediction of disease recurrence were developed. These nomograms can be used to predict the probability of disease recurrence in patients with newly diagnosed Ta, T1 transitional cell carcinoma of the bladder. They may be useful for patient counseling, clinical trial design, and patient follow-up planning.

Abstract
PURPOSE We studied the safety, tolerability and pharmacokinetics of a single immediate post-transurethral resection intravesical instillation of apaziquone for patients with nonmuscle invasive bladder cancer. MATERIALS AND METHODS Patients with cTa-T1, G1-G2 urothelial cell carcinoma of the bladder underwent transurethral resection of bladder tumor(s) followed by a single intravesical instillation of apaziquone 4 mg/40 ml for 1 hour within 6 hours of transurethral bladder tumor resection. Adverse events and safety parameters were assessed on days 8 and 15 after transurethral bladder tumor resection. Blood samples were drawn before and during the instillation for pharmacokinetic analyses. The first 10 patients with pTa-T1, G1-G2 nonmuscle invasive bladder cancer were also evaluated by cystoscopy 3 months after treatment to determine mucosal healing. RESULTS Of 20 patients receiving apaziquone 13 (65%) reported 35 adverse events, mostly grade 1 to 2. Eight patients (40%) reported 13 adverse events related to treatment, in particular dysuria, hematuria, bladder spasm, abdominal pain, asthenia and postoperative urinary retention. Three grade 3 and 1 grade 4 event(s) occurred, but these were considered unrelated to treatment. No other significant clinical changes were observed. Apaziquone and the active metabolite EO5a were not detected with pharmacokinetic analyses at any point of time. After 3 months no evidence of impaired mucosal healing was observed. CONCLUSIONS A single immediate post-transurethral bladder tumor resection instillation of apaziquone was well tolerated with an expected good safety profile. Apaziquone and its metabolite EO5a were not detected systemically with pharmacokinetic analyses. These results have lead to further study of a single immediate instillation of apaziquone.

Abstract
INTRODUCTION The management of transitional bladder cancer, which invades the lamina propria (pT1) and has a marked propensity for recurrence and progression, is controversial. Without adjuvant treatment the recurrence rate can be up to 80% and progression up to 50%. We retrospectively analyzed the incidence of recurrence and progression of pT1 transitional bladder cancer (grade 1-3) after complete transurethral resection of a bladder tumor (TURBT) and adjuvant immunotherapy with bacillus Calmette-Guérin (BCG). MATERIALS AND METHODS 77 patients with stage pT1 transitional cell carcinoma underwent TURBT of all visible tumors and adjuvant BCG intravesical instillations. Before BCG therapy, 12 patients presented with stage pT1 G1 tumors, 50 presented with pT1, and 15 with pT1 G3 tumors. RESULTS 51 patients (66.2%) were disease-free throughout the BCG instillation and follow-up period (median of 45 months); 8 patients (10.4%) experienced recurrence during the BCG instillations, but were disease-free following the last instillation; 16 patients (20.8%) experienced recurrence at a median of 17 months, and 2 patients (2.6%) with pT1 G3 died because of progression. CONCLUSIONS Adjuvant intravesical BCG therapy following TURBT appears to be an effective primary treatment for patients with pT1 transitional cell carcinoma.

Abstract
OBJECTIVE To evaluate the protein expression of fibroblast growth factor receptor-3 (FGFR3), hamartin, 14-3-3sigma, Aurora-A, and E-cadherin using immunohistochemistry (IHC) in a series of human bladder carcinomas and to evaluate their value in distinguishing T1a from T1b tumours and in predicting their behaviour, as T1 urothelial bladder tumours present great diagnostic and therapeutic challenges to pathologists and clinicians. PATIENTS, MATERIALS AND METHODS Tissue microarrays were constructed from 94 patients (Ta 20, T1a 31, T1b 14, and T2 29 patients) using tissue obtained at first disease presentation. RESULTS FGFR3 and 14-3-3sigma were the only markers that were significantly associated with tumour grade and 14-3-3sigma was significantly associated with tumour stage. Furthermore, none of these markers could help in distinguishing T1a from T1b tumours. After adjusting for the E-cadherin expression, FGFR3 expression was a significant factor in predicting the time to recurrence in T1a/T1b. Furthermore, among all the clinical variables, grade and depth of invasion were the only ones that had a significant value in predicting T1a/T1b tumour progression. CONCLUSIONS Even though the staging of T1 to T1a/T1b is not a common practice and it is not included in the Tumour-Node-Metastasis classification, our data clearly confirmed the importance of a proper sub-staging of T1 tumours whenever feasible.

Abstract
Superficial 'nonmuscle-invasive' bladder tumors represent a heterogeneous group of cancers, which include those that are papillary in nature and limited to the mucosa (Ta), high grade, flat and confined to the epithelium (Tis) and those that invade the submucosa or lamina propria (T1). The natural history of these bladder cancers is that of disease recurrence and progression to higher grade and stage. Furthermore, recurrence and progression rates of superficial bladder cancer vary according to several tumor characteristics. The goal in the treatment of superficial bladder cancer is twofold: reducing tumor recurrence and the subsequent need for additional therapies, such as cystoscopy, transurethral resections, intravesical therapy and the morbidity associated with these treatments; and preventing tumor progression and the subsequent need for more aggressive therapy, such as radical cystectomy. The administration of intravesical chemotherapy and immunotherapy has become an important component in accomplishing these goals. This update is the first part of two articles reviewing important contemporary concepts in the etiology, classification and natural history of superficial bladder cancer, while part II of the series will review and highlight important aspects in management of superficial bladder cancer.

Abstract
OBJECTIVES Bladder cancer pathologic features are a continuous spectrum from benign to invasive lesions, causing diagnostic difficulties. Review pathology might be an answer, but appears to be of limited value. We studied the effect of patients' risk profile on the value of review pathology. METHODS We used three Phase III multicenter studies that assessed the value of hexaminolevulinate fluorescence cystoscopy on diagnosis and management. Two studies (Europe and United States) included patients at high risk of carcinoma in situ (CIS), the third study (Europe) included all patients at risk of bladder cancer. Tumors and biopsies were examined by a local and review pathologist. RESULTS The percentage of patients with CIS was high in the first two studies (20.6% and 15.9%) compared with the epidemiologic data (7.9%) and the third study (7.8%). The numbers of patients (specimens) in the three studies were 209 (927), 277 (986), and 142 (553). Overall conformity for both grade and stage was between 50.5% and 56.6%, comparable to published data. Although conformity was best in the high-risk study, this was predominantly because of the better conformity in low-risk tumors. Conformity in Stage T1, CIS, and invasive tumors was low. The results from Europe and the United States were comparable, although the local pathologist in the United States tended to overstage or overgrade. CONCLUSIONS Although histologic conformity was greater in the high-risk patient population, this was mainly a result of pTa tumors. The diagnosis of pT1, CIS, and invasiveness appears difficult. Because these tumors significantly influence therapy, review pathology in patients at high risk or suspicious for high risk should be considered.

Abstract
T1G3 tumours are the most aggressive superficial tumours of the bladder, with a high risk of recurrence and progression. Complete endoscopic resection of the tumour is the first diagnostic and therapeutic step in T1G3 management. A second resection should be done at 1 month to avoid residual tumour and misdiagnosis of a muscle infiltrative cancer. As a result of treatment by instillations of Calmette and Guérin bacillus following endoscopic resection, a 5-year survival rate of 80% has been reported, with 50 to 60% of bladder preservation. BCG is the only conservative treatment that has proven effectiveness on both tumour recurrence and progression. Long term protocols seem to give the best results. Endovesical chemotherapy is not commonly used as its impact on progression has not been demonstrated. Radical cystectomy can be chosen as first line treatment in patients with particularly aggressive tumours. Long term and close surveillance should be achieved in every patient.

Abstract
We sought to review the definition, diagnosis, prognosis, and treatment of high-grade Ta urothelioma carcinoma and carcinomas in situ (CIS) in order to provide evidence-based guidelines for their diagnosis and treatment. The English-language literature on high-grade Ta urothelial carcinoma and CIS was identified and critically reviewed by a panel of 9 international experts. The panel then met at a consensus conference to present their conclusions. Levels of evidence and grades of recommendation were assessed. Findings from approximately 100 publications appearing prior to February 2005 were reviewed and summarized. High-grade Ta urothelial carcinoma and CIS are relatively rare tumors; thus results are often based on small nonrandomized studies. Their assessment is made more difficult owing to inaccuracies in staging and grading. Although there were similar numbers of level 1, level 2, and level 3 evidence citations, guidelines have been developed based only on levels of evidence supporting grade A and grade B recommendations. These evidence-based guidelines have been developed to aid clinicians in the diagnosis and treatment of patients with high-grade Ta urothelial carcinoma and CIS.

Abstract
BACKGROUND Due to the low incidence of squamous cell penile cancer and lack of well-designed studies, controversies persist over the therapeutic approach in patients with pT1 G2 carcinoma. PATIENTS AND METHODS Between 1992 and 2003, 16 patients with T1 squamous penile cancer were treated in our institution either by surveillance or by inguinal lymph node dissection (ILND). RESULTS A total of 8 primary lesions were classified as pT1 G2 carcinoma with 4 tumors developing early or delayed inguinal metastatic disease. CONCLUSIONS The natural behavior of pT1 G2 squamous penile carcinoma and its metastatic potential has been underestimated in recent literature. Since morbidity after early ILND has markedly decreased and its superiority over delayed ILND has been shown, we advocate the early modified inguinal lymph node dissection until strong prognostic factors for positive inguinal lymph nodes have been validated.

Abstract
T1 transitional cell cancer of the urinary bladder is associated with a significant risk of tumor progression when transurethral resection (TUR) is the only treatment. Additional intravesical immunotherapy can reduce this risk; however, long-term results of more than 15 years of follow-up indicate that almost half of the patients may lose their bladder or even die due to recurrent tumor. The alternative to TUR is cystectomy at either the initial presentation or time of first recurrence. However, although the results of this treatment strategy are encouraging, an unknown percentage of patients will lose their bladder and go on to experience all possible complications of urinary diversion unnecessarily. The central issue of conservative treatment but also the indication for cystectomy is the quality of TUR. From the present literature, it is evident that a 'textbook TUR' cannot be performed on every patient, i.e. macroscopical clearance of the bladder from tumor, separate thorough resection of the tumor base and separate biopsies of the borders of the resection area. Moreover, even in cases of a so-called 'correct TUR', a significant percentage of residual tumor is left behind and will be the source of local recurrence or progression. In addition, TUR specimens may be difficult to diagnose accurately, especially in respect to grade and stage. Recent publications demonstrate that the routinely performed second TUR detects residual tumors of similar or higher stage in a significant percentage of patients. The clinical implications of these findings can be considerable as the absence or presence of tumor may determine whether patients undergo conservative or aggressive treatment. Moreover, results of retrospective studies support this suggestion. Currently, there is no standard appropriate treatment of T1 tumors. However, we strongly recommend that future studies on the conservative treatment of T1 tumors include a second TUR within 2 to 4 weeks after the first one.

Abstract
BACKGROUND Cell cycle proteins are important markers in predicting tumor behavior in urothelial carcinoma of the bladder. The objectives of this study were 1) to determine the expression levels of some of those markers in a series of patients with bladder carcinoma, 2) to define their value in distinguishing T1a (minimally invasive) from T1b (invasive) tumors, and 3) to evaluate their use as predictive factors in the progression of T1a and T1b tumors. METHODS Tumor specimens from 101 patients were included (22 Ta specimens, 34 T1a specimens, 15 T1b specimens, and 30 T2 specimens). A tissue microarray from the 101 paraffin embedded tissue blocks was constructed. Immunohistochemistry for p16, p27, p21, p53, cyclin D1, and Ki-67 were performed. To evaluate T1a and T1b tumor progression, clinical and follow-up data were available for all 49 patients. RESULTS Cyclin D1 and p27 were the only markers that showed a significant association with tumor stage and tumor grade (cyclin D1: P = 0.002 and P > 0.00, respectively; p27: P = 0.024 and P = 0.031, respectively). The results indicated that a combination of p21 (odds ratio, 5.7; 95% confidence interval [95% CI], 1.3-24.8 [P = 0.022]) and p16 (odds ratio, 3.7; 95% CI, 0.8-16.5 [P = 0.081]) may have potential use in distinguishing T1b tumors from T1a tumors. Finally, none of the markers examined were found to have predictive value for T1a and T1b tumor progression. CONCLUSIONS The expression of cyclin D1 and p27 was associated with the most important prognostic factors (tumor stage and grade). The combination of p21 and p16 may have value in distinguishing T1b tumors from T1a tumors, although this finding must be evaluated in much larger series. Finally, none of the markers studied appeared to have predictive value for disease progression in patients with T1a and T1b urothelial bladder tumors.

Abstract
PURPOSE OF REVIEW In this review new modalities in the diagnosis, staging and treatment of superficial and invasive bladder cancer are reviewed. RECENT FINDINGS Urinary markers still cannot replace cystoscopy in diagnosing bladder cancer. However, DNA micro-array has shown promise for diagnosis. In the treatment of superficial bladder cancer, valrubicin, pirarubicin and gemcitabine are novelties. Furthermore, a combination therapy of hyperthermia and mitomycin-C as well as photodynamic therapy seem to be safe and effective new treatment modalities. For staging, computed tomography, magnetic resonance imaging and the positron emission tomography scan are limited. Nevertheless, the pT-category, pN-category and the number of lymph nodes removed affect survival significantly and are thus useful for staging and prognosis. This indicates a need for a standardized lymph node dissection in cystectomy patients. SUMMARY In the treatment of invasive bladder cancer, prostate-sparing cystectomy shows promising potency and continence results. In advanced disease, gemcitabine-cisplatin is a valuable alternative to methotrexate-vinblastine-doxorubicin-cisplatin with fewer side-effects. Finally, radical radiotherapy should be considered a valid treatment in patients with invasive bladder cancer.

Abstract
OBJECTIVE To establish prognostic factors of recurrence and progression in stage T1 transitional cell bladder carcinoma, paying special attention to prognostic value of p53 and ki67. MATERIALS AND METHODS 175 patients with incident bladder tumour at T1 category. The immunohistochemical study was performed using the monoclonal antibodies DO-7, for p53 and MIB-1, for ki67. Kaplan-Meier methodology was used, and a multivariate analysis using Cox's proportional hazards model was carried out in order to determine the variables associated with recurrence and progression. ROC curves were also drawn up. RESULTS The average follow up period was 8.55 years. 5 and 12-year recurrence-free survival rates were 57.98% and 48.47%. The independent variables for recurrence were histological grade, tumour multifocality, tumour size > 3 cm, presence of carcinoma in situ and ki67 expression. 5 and 12-year progression-free survival rates were 83.12% and 75.63%. The independent variables for progression were age, tumour multifocality, solid microscopic morphology, p53 expression and ki67 expression. CONCLUSIONS Solid microscopic pattern and p53 expression are the variables which best predict progression. A positive relationship was observed between p53 and progression: the greater the expression of p53, the greater the progression. Tumour multifocality and ki67 expression > 27% are the main prognostic factors for recurrence.

Abstract
PURPOSE The subclassification of T1 bladder tumors into T1A and T1B has an important prognostic significance and a great impact on patient management. Unfortunately, staging T1 tumors is highly subject to interpathologist variation that can be critical for patients included in randomized clinical trials. To determine the value of immunohistochemistry (IHC), such as desmin and keratin, in comparison to hematoxylin-eosin (H&E) in classifying T1 stage disease, we retrospectively examined 93 consecutive cases diagnosed at our department. MATERIALS AND METHODS The study was conducted in two phases (H&E then IHC), each in two time periods. First H&E, and then IHC slides were reviewed independently by two experienced pathologists and discrepant cases from each phase were discussed between the two pathologists to reach a final decision. RESULTS The two methodologies (H&E and IHC) showed total agreement in 76 out of 93 cases. IHC downstaged seven cases, that is from T1B to T1A, upstaged four cases, that is from T1A to T1B, lowered the rate of imprecision and eliminated the disagreement between the two pathologists. However, IHC failed to subclassify T1 tumors in three cases. Finally, the discussion supported by the IHC was very useful in reaching the diagnosis in some cases. CONCLUSIONS IHC appears to be a useful tool in staging T1 bladder cancer, especially in difficult cases where specimen orientation and artifact could create a major hindrance in reaching an accurate diagnosis.

Abstract
BACKGROUND Determination of prognosis factors associated with survival, recurrence, progression, and development of metastasis in T1 and T2a transitional cell carcinoma (TCC) of the bladder is discussed. METHODS A study was conducted of a group of 210 patients with primary bladder TCC at classification T1 (n = 175) and T2aN0M0 (n = 35). A total of 177 variables were studied in each patient. The monoclonal antibodies used were the following: DO7 (p53) and MIB-1 (Ki-67). Prognosis was obtained using Kaplan-Meier methodology and Cox proportional hazards model. RESULTS The average follow-up period was 6.7 years. Cancer-related survival rates at 5 and 10 years were 82.96% and 74.78%, respectively. The independent survival variables were the following: age and expression of p53. Recurrence free survival at 5 and 10 years stood at 51.80% and 42.71%, respectively. The independent recurrence variables were T2a classification, tumor multifocality, tumor size of greater than 3 cm, carcinoma in situ in random biopsy, and expression of Ki-67. Progression free survival rates at 5 and 10 years were 75.31% and 69.16%, respectively. The independent progression variables were age, T2a classification, and expression of p53. Metastasis free survival rates at 5 and 10 years stood at 87.23% and 84.55%, respectively. The expression of p53 was the sole variable to provide an independent prediction of metastasis. CONCLUSIONS The expression of p53 clearly has an independent effect on the prediction of survival, progression and development of metastasis, showing a dose-response effect. Tumor multifocality and T2a classification are the variables that best predict recurrence.

Abstract
The number of genes suggested to play a role in cancer biology is rapidly increasing. To be able to test a large number of molecular parameters in sufficiently large series of primary tumours, a tissue microarray (TMA) approach has been developed where samples from up to 1000 tumours can be simultaneously analysed on one glass slide. Because of the small size of the individual arrayed tissue samples (diameter 0.6 mm), the question arises of whether these specimens are representative of their donor tumours. To investigate how representative are the results obtained on TMAs, a set of 2317 bladder tumours that had been previously analysed for histological grade and Ki67 labelling index (LI) was used to construct four replica TMAs from different areas of each tumour. Clinical follow-up information was available from 1092 patients. The histological grade and the Ki67 LI were determined for every arrayed tumour sample (4x2317 analyses each). Despite discrepancies in individual cases, the grade and Ki67 information obtained on minute arrayed samples were highly similar to the data obtained on large sections (p<0.0001). Most importantly, every individual association between grade or Ki67 LI and tumour stage or prognosis (recurrence, progression, tumour-specific survival) that was observed in large section analysis could be fully reproduced on all four replica TMAs. These results show that intra-tumour heterogeneity does not significantly affect the ability to detect clinico-pathological correlations on TMAs, probably because of the large number of tumours that can be included in TMA studies. TMAs are a powerful tool for rapid identification of the biological or clinical significance of molecular alterations in bladder cancer and other tumour types.

Abstract
PURPOSE Pathological interpretations are largely subject to interpathologist and intrapathologist variation. Differences in tumor stage and grade exist in local and review pathological findings in patients with stage Ta-T1 bladder tumors who are entered in randomized trials of adjuvant treatment after transurethral resection. Because they are diagnosed and treated based on local pathological results, it is important to determine the reliability of local pathological evaluations and the extent to which pathology review may change the treatment decision process. MATERIALS AND METHODS We assessed local and review pathology results in 1,400 patients treated in 5 European Organization for Research and Treatment of Cancer randomized phase III trials comparing various adjuvant prophylactic treatment strategies for primary or recurrent stage Ta-T1 transitional cell bladder cancer. RESULTS We noted large variations in T category and grade. Pathology review down staged T category to stage Ta in 53% of cases originally classified as stage T1. There was agreement in only 57% and 50% of stage Ta grade 1 and stage T1 grade 3 cases, of which 10% were reclassified as muscle invasive disease greater than stage T1. While T category and grade have prognostic importance, differences in the prognosis based on local and review pathological studies were slight. CONCLUSIONS Pathology review is not mandatory in low and intermediate risk cases since it has little impact on the prognosis and treatment decision making. In high risk cases of stage T1 grade 3 disease stage or grade is often changed, so that review remains essential in this subgroup.

Abstract
OBJECTIVE Crohn's disease (CD) and ulcerative colitis (UC) may both affect the colon. However, in approximately 10-20% of these cases, it is impossible to distinguish between these two entities either clinically or histologically, and a diagnosis of indeterminate colitis (IC) is made. Correct diagnosis is important because surgical treatment and long-term prognosis differ for UC and CD. The purpose of this study was to determine the extent of interobserver agreement among board-certified pathologists and a specialist gastrointestinal (GI) pathologist regarding the histological diagnosis of colonic inflammatory bowel disease (IBD). METHODS A total of 24 university medical center pathologists from eight institutions evaluated 84 colectomy specimens and 35 sets of biopsy specimens from 119 consecutive patients with colonic IBD. A specialist GI pathologist subsequently reviewed all cases without knowledge of clinical data and prior diagnosis. RESULTS The GI pathologist's diagnoses differed from the initial diagnoses in 45% of surgical specimens and 54% of biopsy specimens. Of 70 cases initially diagnosed as UC, 30 (43%) were changed to CD or IC, whereas 4 of 23 cases (17%) initially diagnosed as CD were changed to UC or IC. The kappa coefficient for the overall agreement of initial diagnoses with the specialist GI pathologist's diagnoses was -0.01 (p = 0.98). CONCLUSIONS There is significant interobserver variation in the histological diagnosis of colonic IBD. This may have a profound effect on clinical patient care and, especially, on the choice of operation. More accurate diagnostic criteria are needed to facilitate patient care and to optimize treatment outcome.

Abstract
PURPOSE We identified risk groups in primary superficial bladder cancer according to progression, mortality and recurrence rates. MATERIALS AND METHODS The prognostic factors of progression, mortality and recurrence were identified by multivariate analysis in a cohort of 1,529 patients with primary superficial bladder cancer. Risk groups were designed by combining the relative risk of these prognostic factors. We performed survival analysis of progression, tumor mortality and recurrence by risk group using the Kaplan-Meier method. Relative risk in each group was calculated by Cox regression. We present timetables of progression, mortality and recurrence by risk group. RESULTS Risk groups were classified as low-grade 1 stage Ta disease and a single grade 1 stage T1 tumor, intermediate-multiple grade 1 stage T1 tumors, grade 2 stage Ta disease and a single grade 2 stage T1 tumor, and high-multiple grade 2 stage T1 tumors, grade 3 stages Ta and T1 disease, and any stage disease associated with carcinoma in situ. Survival analysis of progression, mortality and recurrence revealed a statistically significant difference among the 3 risk groups. The rates of recurrence, progression and mortality were 37%, 0% and 0% in the low, 45%, 1.8% and 0.73% in the intermediate, and 54%, 15% and 9.5% in the high risk group, respectively. The relative risks of recurrence, progression and mortality in the low versus the intermediate and high risk groups were 1.37, 2.84 and 1, and 1.87, 24.76 and 14.69, respectively. CONCLUSIONS Risk group classification based on prognostic factors defines progression, mortality and recurrence rates in primary superficial bladder cancer. It may be useful for designing treatment and followup strategies.

Abstract
PURPOSE We evaluate the prognostic factors of recurrence, progression and disease specific mortality in patients with primary superficial Ta and T1 transitional cell carcinoma of the bladder. MATERIALS AND METHODS We studied a cohort of 1,529 patients with primary superficial transitional cell carcinoma of the bladder treated with transurethral resection and random bladder biopsies. Mean followup was 4.2 years. Statistical analysis was performed using the Kaplan-Meier method and multivariate analysis was done with the Cox proportional hazards model with stepwise forward selection. All p values were 2-sided, with odds ratios and 95% confidence intervals. RESULTS Multiple tumors (odds ratio 2), tumor greater than 3 cm. (1.65) and carcinoma in situ (1.6) increased, whereas intravesical bacillus Calmette-Guerin (BCG) instillations (0.39) decreased the risk of recurrence. Grade 3 disease (odds ratio 19.9), multiple tumors (1.9), tumor greater than 3 cm. (1.7) and carcinoma in situ (2.1) increased, whereas BCG (0.3) decreased the risk of progression. Grade 3 disease (odds ratio 14) and carcinoma in situ (odds ratio 3) increased the risk of disease specific mortality. CONCLUSIONS Neither tumor stage nor dysplasia influenced tumor evolution. Multiple tumors, tumor greater than 3 cm. and intravesical BCG instillations were risk factors of recurrence and progression. Carcinoma in situ influenced recurrence, progression and disease specific mortality. Finally, the main predictor of progression and mortality was grade 3 disease.

Abstract
OBJECTIVE To assess the reliability of the histological diagnosis of bladder cancer by assessing the interobserver variability of staging and grading in pTa/pT1 tumours and evaluating the clinical significance of discrepancies. MATERIALS AND METHODS All sections from 301 superficial bladder carcinomas were reviewed by one pathologist. The prognostic relevance of grade and stage from both the initial and review diagnosis were determined in 128 patients for whom there was long-term follow-up information. RESULTS There were significant interobserver differences in both the grading and staging of tumours. From a total of 235 tumours that were initially considered pT1, the reviewer classified 35% as pTa, 56% as pT1, 6% as pT1- (at least pT1), and 3% as pT2-4. In 39% of all biopsies there were interobserver differences in tumour grade. The prognostic significance of grade and stage differed between the initial pathology report and the reviewer's diagnosis. The reviewer's staging allowed a better estimate of the risk of subsequent tumour progression than the initial staging. Progression was significantly more common in 49 tumours in which the reviewer agreed with stage pT1 than in 29 tumours that were down-staged from pT1 to pTa (P = 0.0116). However, the initial tumour grade (P = 0.0386) but not the reviewer's grade (P = 0.2645) was significantly linked to progression. CONCLUSIONS These results show that grading and staging by different pathologists have varying prognostic implications. If possible, biopsies from bladder tumours should be independently evaluated by two different pathologists before radical therapy is administered.

Abstract
OBJECTIVES To evaluate microstaging by means of quantifying the depth of invasion of the subepithelial connective tissue in pT1 transitional cell carcinoma (TCC) of the bladder for its additional prognostic value with respect to disease recurrence and progression. METHODS We reviewed the pathologic findings of a consecutive series of 124 patients with pT1 tumors entered in a prospective randomized multicenter trial comparing mitomycin C and bacillus Calmette-Guérin treatment, with at least 3 years of follow-up and clinical outcome hidden from reviewers. The depth of invasion was established by identifying submucosal tumor invasion up to, in, or beyond the muscularis mucosae or vascular plexus and classified as pT1a, pT1b, or pT1c, respectively. In addition to tumor grade, the presence of carcinoma in situ (CIS) near the primary tumor or in biopsy specimens taken from abnormal looking mucosa was taken into account. The risks of recurrence and progression were calculated using Kaplan-Meier curves and modeled with proportional hazard models. RESULTS pT1 subclassification was possible in more than 90% of the specimens. The 3-year risk of recurrence was not different in any of the subgroups. By contrast, the Kaplan-Meier 3-year risk for progression was 6%, 33%, and 55% for pT1a, pT1b (hazard ratio [HR] 5.51), and pT1c (HR 12.35) tumors, respectively (log-rank test P < 0.001). The Kaplan-Meier 3-year risk of progression was 9% versus 39% (HR 5.62) for the absence or presence of CIS in the tumor (P=0.001) and 8% versus 49% (HR 6.72) for CIS in biopsy specimens (P < 0.001). Tumor grade had no statistically significant prognostic value with respect to progression, nor had tumor volume or multifocality. The combination of the parameters (pT1c and CIS) increased the risk of progression by a factor of 27 (P < 0.0001) compared with the absence of pT1c and CIS. CONCLUSIONS These data show that the extent of lamina propria invasion (pT1a, pT1b, pT1c) is a clinically relevant prognostic factor for progression of pT1 TCC of the bladder. With the combination of this pT1 subclassification and the presence of CIS subgroups, distinct risks of progression can be identified that may give additional information for follow-up and treatment policies.
