Abstract
PURPOSE We evaluated the survival of patients with muscle invasive bladder cancer undergoing radical cystectomy without neoadjuvant chemotherapy to confirm the utility of existing clinical tools to identify low risk patients who could be treated with radical cystectomy alone and a high risk group most likely to benefit from neoadjuvant chemotherapy. MATERIALS AND METHODS We identified patients with muscle invasive bladder cancer who underwent radical cystectomy without neoadjuvant chemotherapy at our institution between 2000 and 2010. Patients were considered high risk based on the clinical presence of hydroureteronephrosis, cT3b-T4a disease, and/or histological evidence of lymphovascular invasion, micropapillary or neuroendocrine features on transurethral resection. We evaluated survival (disease specific, progression-free and overall) and rate of pathological up staging. An independent cohort of patients from another institution was used to confirm our findings. RESULTS We identified 98 high risk and 199 low risk patients eligible for analysis. High risk patients exhibited decreased 5-year overall survival (47.0% vs 64.8%) and decreased disease specific (64.3% vs 83.5%) and progression-free (62.0% vs 84.1%) survival probabilities compared to low risk patients (p <0.001). Survival outcomes were confirmed in the validation subset. On final pathology 49.2% of low risk patients had disease up staged. CONCLUSIONS The 5-year disease specific survival of low risk patients was greater than 80%, supporting the distinction of high risk and low risk muscle invasive bladder cancer. The presence of high risk features identifies patients with a poor prognosis who are most likely to benefit from neoadjuvant chemotherapy, while many of those with low risk disease can undergo surgery up front with good expectations and avoid chemotherapy associated toxicity.

Abstract
PURPOSE To determine the prognostic significance of lymphovascular invasion (LVI) in patients with urothelial carcinoma of the bladder undergoing radical cystectomy (RC) and bilateral pelvic lymph node dissection. METHODS From 1992 to 2008, 526 patients underwent RC and pelvic lymphadenectomy at our institution by a single surgical team. All relevant data were entered into a database and analyzed. LVI was defined as "the presence of tumor cells within an endothelial lined space." The exclusion criteria were non-TCC histology, salvage cystectomy, neoadjuvant chemotherapy, and unknown LVI status. RESULTS A total of 357 patients met the inclusion criteria. Overall prevalence of LVI was 29%. LVI was significantly associated with higher T stage, lymph node (LN) metastases, and higher grade. Patients with LVI had significantly higher recurrence rate (P < 0.001) and decreased long-term survival (P < 0.001). In patients without LN metastases, LVI in the primary led to a significantly decreased recurrence-free (P = 0.003) and disease-specific survival (P = 0.001). In the presence of LN metastases, LVI did not significantly alter the recurrence-free or disease-specific survival. On multivariate analysis, T stage (P < 0.0001) and LN metastases (P = 0.01) were significant independent prognostic factors influencing disease-specific survival. LVI did not have independent prognostic value. T stage was the only significant prognostic factor in the lymph node negative group. CONCLUSIONS Although, the presence of LVI in node-negative patients is an adverse prognostic factor on univariate analysis of disease-specific survival, it is not an independent prognostic factor on multivariate analysis. Pathological stage is the only independent prognostic factor for survival.

Abstract
Significant progress has been made in the standardization of bladder neoplasm classification and reporting. Accurate staging using the American Joint Committee on Cancer/International Union Against Cancer (AJCC/UICC) TNM system is essential for patient management, and has been reinforced by clinical evidence in recent years. It is now recognized that 'superficial' bladder carcinomas are a heterogenous group of tumors with diverse biological and clinical manifestations. The term 'superficial,' therefore, is no longer used for bladder tumor nomenclature. Recognition of diagnostic pitfalls associated with lamina propria invasion is critical for the evaluation of bladder tumor specimens. Neither the 1973 nor the 2004 WHO grading system appears to be useful for predicting the clinical outcome of invasive urothelial carcinoma. This review will discuss recent progress and controversial issues on the staging and substaging of bladder carcinomas. Essential elements for handling and reporting of bladder tumor specimens will also be discussed.

Abstract
PURPOSE We compared and evaluated clinical outcomes in patients with pathological superficial (pT2a) and deep (pT2b) invasion of bladder muscle with transitional cell carcinoma following radical cystectomy and urinary diversion. MATERIALS AND METHODS From 1971 to 2001, 311 of 1,359 patients (23%), including 244 males (78%) and 67 females, were found to have pathological muscle invasive (pT2) bladder cancer following radical cystectomy. Of this group 147 patients (47%) had pT2a (superficial) and 164 (53%) had pT2b (deep) muscle invasive tumors. Overall 242 patients had no evidence of lymph node metastasis, including 127 with pT2a (86%) and 115 with pT2b (70%). A total of 69 patients (22%) had lymph node involvement, including 20 with pT2a (14%) and 49 with pT2b (30%). At a median followup of 14.3 years (range 0 to 30.1) clinical outcomes were determined, including recurrence-free and overall survival, and local vs distant recurrence. RESULTS In the 311 patients with pT2 tumors 10-year recurrence-free and overall survival rates were 72% and 47%, respectively. There was a significantly higher risk of node positive disease with pT2b vs pT2a tumors (30% vs 14%, p <0.001). No significant difference was observed in 10-year recurrence-free survival in patients with pT2a node negative vs pT2b node negative tumors (84% vs 72%, p = 0.091). When comparing pT2a node positive vs pT2b node positive tumors, no significant difference was observed in 10-year recurrence-free survival (50% vs 48%, p = 0.84). Recurrence-free survival was significantly higher in patients with pT2 lymph node negative tumors than in those with pT2 lymph node positive tumors (79% vs 49%, p <0.001). Furthermore, these differences remained significant when stratified by pT2a and pT2b node negative vs positive disease. Local pelvic recurrence developed in 10 of 311 patients (3%) with pT2 disease, while 69 (22%) had distant metastatic disease. In patients with recurrence the local or distant recurrence site was not associated with tumor stage (pT2a vs pT2b p = 0.24) or lymph node status (node negative vs positive p = 0.37). CONCLUSIONS In muscle invasive (pT2) bladder cancer treated with radical cystectomy there is a higher risk of lymph node positive disease in deep muscle (pT2b) vs superficial (pT2a) invasion. However, no apparent difference was observed in recurrence-free survival between pT2a (superficial) vs pT2b (deep) muscle invasive tumors when controlling for lymph node status. Recurrence-free survival is significantly improved in patients with pT2 lymph node negative tumors compared to survival in those with pT2 lymph node positive tumors. Patients with muscle invasive (pT2), lymph node negative tumors have excellent clinical outcomes following cystectomy, while those with muscle invasive (pT2), lymph node positive tumors have higher recurrence rates and should be considered for adjuvant treatment protocols.

Abstract
The most effective non-surgical treatment for bladder cancer remains radiotherapy. The dramatic technical developments in radiotherapy have enabled greater accuracy and reliability based on three-dimensional imaging for both planning and verification. Particle therapy, in particular using protons, provides further opportunities for optimising radiation delivery and dose escalation. Novel fractionation schedules with both hyperfractionation and hypofractionation may have added benefits. Chemoradiation has been shown in one randomised-controlled trial to improve the results of radiotherapy alone, and requires further investigation. Hypoxia modification using carbogen and nicotinamide has also shown promising results in a phase II trial, and is now in phase III evaluation. Novel drug agents for bladder cancer are few, but the anti-EGFR agents and anti-angiogenic agents may have promise; the development of anti-apoptotic agents and antisense gene therapy may also become a component of the future multimodality management of this tumour.

Abstract
PURPOSE We determined the prognostic significance of lymphovascular invasion (LVI) in patients treated for invasive transitional cell carcinoma of the bladder with radical cystectomy. MATERIALS AND METHODS From August 1971 to June 2004, 2,005 patients underwent radical cystectomy for primary bladder cancer with intent to cure. All patients with nontransitional cell carcinoma histology, palliative procedures, unknown lymphovascular status, less than pT1 pathological stage, or any neoadjuvant or adjuvant chemotherapy/radiation therapy were excluded, leaving 702 comprising the study cohort. Of the 702 patients 249 (36%) had LVI. RESULTS Median followup was 11.0 years (range 8 days to 23.2 years). Overall 5 and 10-year survival was 51% and 34%, while 5 and 10-year recurrence-free survival was 66% and 64%, respectively. Ten-year recurrence-free survival in patients without LVI was 74% compared with 42% in those with LVI (p <0.0001). Similarly 10-year overall survival was 43% in patients without LVI compared with 18% in those with LVI (p <0.0001). In the organ confined/lymph node negative and lymph node positive pathological subgroups survival outcomes were significantly worse if LVI was present. Although a trend was observed, LVI status was not statistically significant in patients with extravesical node negative disease. Stepwise Cox regression analysis revealed that pathological subgroup (organ confined, extravesical and lymph node positive) (p <0.0001) and LVI status (p = 0.0004) were independent prognostic variables for recurrence-free and overall survival. CONCLUSIONS Lymphovascular invasion appears to be an important and independent prognostic variable in patients with invasive bladder cancer treated with radical cystectomy. LVI status should be determined in cystectomy specimens, which may provide further risk stratification in patients following radical cystectomy.

Abstract
OBJECTIVE To identify the clinical and pathological prognostic factors in a homogeneous series of patients with bladder cancer who had undergone radical cystectomy in the late 1990s. MATERIALS AND METHODS We retrospectively analyzed the clinical data of 156 patients who had undergone radical cystectomy and iliac-obturator lymphadenectomy for bladder carcinoma at our department between 1995 and 2001. RESULTS The mean follow-up was 39.71 +/- 26.2 months. The 5-year overall and cancer-specific survival rates were 47.2 and 54.7%, respectively. Upper urinary tract obstruction (p = 0.03), clinical stage of both the primary tumor (p = 0.0001) and loco-regional lymph nodes (p = 0.04), pathological stage (2002 TNM) of the primary tumor (p < 0.0001), pathological loco-regional lymph node involvement (p < 0.0001), and vascular embolization (p = 0.005) were significant on univariate analysis. Pathological lymph node involvement (p = 0.001) and both pathological (p = 0.022) and clinical stages of the primary tumor (p = 0.002) turned out to be independent predictors of cancer-specific survival. CONCLUSION Pathological lymph node involvement, clinical and pathological stage of the primary tumor were the cancer-specific, survival-independent, predictors in our series. Our multivariate analysis data identified pT3-4 and pN+ patients as those with the worst prognosis.

Abstract
BACKGROUND The objective of this study was to determine whether vascular invasion (i.e. lymphatic and blood vessel invasion) could be a useful prognostic predictor in patients with locally invasive transitional cell carcinoma (TCC) of the bladder who underwent radical cystectomy. METHODS This series included 114 consecutive patients undergoing radical cystectomy for primary TCC of the bladder between November 1989 and July 2003. Several clinicopathological characteristics of these patients were analyzed, focusing on the association between vascular invasion and disease recurrence after radical cystectomy. RESULTS Lymphatic and blood vessel invasions were detected in 55 (48.2%) and 33 (29.8%) specimens, respectively. Lymphatic invasion was significantly associated with pathological stage, tumor grade, lymph node metastasis, blood vessel invasion and disease recurrence, whereas blood vessel invasion was significantly related to pathological stage, lymph node metastasis, lymphatic invasion and disease recurrence. Recurrence-free survival in patients with lymphatic invasion was significantly lower than that in those without lymphatic invasion, and a similar significant difference in recurrence-free survival was observed between patients with and without blood vessel invasion. However, multivariate analysis using the Cox proportional hazards model showed that only pathological stage and lymph node metastasis could be used as independent predictors for disease recurrence after radical cystectomy. CONCLUSIONS Despite a significant association between several prognostic parameters, vascular invasion was not an independent predictor of disease recurrence; therefore, if there are other conventional parameters available, there might not be any additional advantage to considering the presence of vascular invasion when predicting the prognosis of patients undergoing radical cystectomy for TCC of the bladder.

Abstract
PURPOSE To investigate the tolerance and efficacy of a modified concurrent chemoradiation (CCRT) protocol for patients with invasive bladder cancer "unfit" for radical cystectomy. METHODS AND MATERIALS Twenty-three muscle-invasive bladder cancer patients who were unfit for or unwilling to receive radical cystectomy were enrolled in this study. All patients had transitional cell carcinoma of bladder, and distribution of stage was 14 (61%), 1 (4%), and 8 (35%) for T3a, T3b, and T4, respectively. This study included a relatively old-age population, with the median age being 75 and 70% of patients over 70 years old. Patients were treated with maximal transurethral resection of the bladder tumor followed by curative CCRT. The chemotherapy (C/T) regimen was comprised of cisplatin, 50 mg/m(2) intravenously (i.v.) on Day 1; 5-fluorouracil (5-FU), 500 mg/m(2)/day by continuous i.v. infusion on Days 1-3; and leucovorin, 50 mg/day by continuous i.v. infusion on Days 1-3. Chemotherapy course was repeated at 21-day intervals. The radiation dose was 44-45 Gy to whole pelvis and 60-61.2 Gy to bladder, with a daily fraction of 1.8-2 Gy. The completeness of the CCRT protocol was defined as patients receiving at least 55 Gy of radiotherapy to the whole bladder and at least three courses C/T. RESULTS Seventy-four percent of patients (17/23) completed the CCRT protocol. Radiation Therapy Oncology Group (RTOG) Grade 3 acute toxicities were observed in 4 patients, which included leucopenia, vomiting, genitourinary (GU) tract infection, and diarrhea. No treatment-related deaths occurred during the CCRT period. RTOG Grade 3 or more late complications were observed in 3 patients; one of them died of radiation cystitis superimposed with GU infection. Of the 18 patients whose response to CCRT was evaluated, a complete tumor response was documented in 16 patients (89%). With a median follow-up of 3 years, the 3-year overall survival (OS) and disease-free survival (DFS) for all patients was 69% and 65% respectively. Meanwhile, the 3-year overall and DFS rates for patients who completed CCRT vs. those who did not complete CCRT were 82% vs. 33% and 75% vs. 33%, respectively (p = 0.18 for OS and p = 0.04 for DFS). CONCLUSIONS Concurrent cisplatin, 5-FU, leucovorin, and radiotherapy for treatment of invasive bladder cancer is a feasible and promising treatment even for relatively old patients. Our results are comparable to those in recent studies by using combined modality treatment or neoadjuvant chemotherapy plus radical cystectomy. Consequently, this novel protocol warrants a prospective clinical trial and may be a safe, effective alternative to radical cystectomy.

Abstract
PURPOSE Data on the prognostic significance of tumor invading lymphatic and blood vessels in bladder cancer are controversial, while little is known about perineural invasion in this tumor. We determined the prognostic value of these parameters in radical cystectomy specimens. MATERIALS AND METHODS Slides of 283 radical cystectomy specimens obtained from 1986 to 1997 were examined retrospectively with respect to tumor invasion in lymphatic and blood vessels, and perineural spaces. This review was performed while blinded to lymph node tumor involvement or the postoperative disease course. The Kaplan-Meier probability analysis of tumor-free survival and the log rank test were used to determine the prognostic effects of vascular and perineural invasion. Multivariate analysis using the Cox proportional hazards model was also performed. RESULTS Lymphatic, blood vessel and perineural tumor invasion were present in 54.1%, 13.1% and 47.7% of specimens, respectively. Tumor progressed in 46.3% of patients. On univariate analysis all 3 factors showed strong prognostic significance. However, on multivariate analysis only blood vessel invasion, invasion depth and regional lymph node status were independent prognostic factors (p <0.05). CONCLUSIONS Lymph node metastases, pT classification and blood vessel invasion are independent prognostic parameters of tumor-free survival that should be used to guide patient treatment after radical cystectomy. Invasion of the blood and lymphatic vessels should be commented on separately in the pathology report.

Abstract
OBJECTIVE To study the survival of patients with bladder cancer and infiltration into the muscle who undergo radical cystectomy, documenting any survival difference based on the depth of muscle infiltration (pT2a vs. pT2b). MATERIAL AND METHOD 109 patients with infiltration into the muscle (T2) in the TUR were treated with radical cystectomy between 1986 and 1996; 39 patients were excluded due to infra-staging and 2 died in the immediate postoperative: 68 patients were eligible for the study. Median follow-up was 51 months. At the time of analysis 44 were alive (2 with tumoral disease and one with a second non-urological tumour), 21 had died (4 for causes other than vesical tumour) and 3 patients were considered lost to follow-up at 3, 31 and 111 months. Survival analysis was performed using the Kaplan-Meier method, and the variables were compared with the log-rank test. RESULTS The 3- and 5-year overall survival of our series was 76% and 62%, while cancer specific survival was 80% and 70% respectively. Cancer specific survival at 5 years by stages was: pT0-83%, pT1-80%, pT2a-66% and pT2b-60% (p = 0.52). The cystectomy specimen (pT0) showed no residual tumour in 15 (22%) patients, and 5-year cancer specific survival in this group was 83% vs. 66% in patients with residual cancer (p = 0.24). CONCLUSIONS Patients with pT2a and pT2b bladder cancer showed no differences in survival and we believe they should be all included in the same prognostic group (pT2). pT0 patients are a subgroup of patients with significant survival rates in which radical cystectomy should be considered as overtreatment, and a more conservative protocol should be preferred.

Abstract
BACKGROUND Accurate examination of radical cystectomy specimens is critical for stratifying patients into prognostically important groups and determining the need for adjuvant treatment. Evidence has accumulated that cancers invading the superficial muscle wall (T2a) behave similarly to those invading the deep muscle wall (T2b). Quantitative analysis of the depth of invasion in relation to patient outcome is needed. METHODS The authors systematically evaluated the depth of invasion by micrometer measurement and its relation to the survival of 64 patients with bladder carcinoma pathologic classification as pT2 who had long term follow-up after radical cystectomy. Numerous clinical and pathologic variables were analyzed with univariate and multivariate Cox proportional hazards models. The mean age of patients was 64 years, and their mean follow-up was 8.3 years. RESULTS There was no significant difference in clinical outcome between patients with T2a carcinoma and those with T2b. Lymph node metastasis and tumor size were each significantly associated with distant metastasis free and cancer specific survival. Ten-year distant metastasis free and cancer specific survival were 100% and 94%, respectively, for patients with tumors <3 cm (P = 0.006) and 68% and 73%, respectively, for patients with tumors > or = 3 cm (P = 0.005). After adjustment for lymph node status, tumor size maintained significance in predicting distant metastasis free survival (risk ratio, 1.5; 95% confidence interval, 1.1-2.0; P = 0.009) and cancer specific survival (risk ratio, 1.5; 95% confidence interval, 1.1-1.9; P = 0.01). Age was associated with recurrence free survival and all-cause survival. None of the other variables, including gender, vascular invasion, presence of carcinoma in situ, pathologic classification (T2a vs. T2b), depth of invasion, depth of muscle invasion, ratio of depth of invasion to bladder wall thickness, and percentage of muscle wall invasion, were significantly associated with patient outcome. CONCLUSIONS The findings of this study indicate that the subclassification of T2 bladder carcinoma by depth of muscle invasion is of no prognostic value; conversely, tumor size, an easily measured factor, is predictive of distant metastasis free and cancer specific survival.

Abstract
OBJECTIVE To determine whether epidermal growth factor receptor (EGFR) immunostaining of tumour cells is associated with cancer-specific death after cystectomy for locally advanced bladder cancer. PATIENTS AND METHODS The hospital records of all patients treated with cystectomy for urothelial cancer of the urinary bladder between 1967 and 1992 were reviewed retrospectively. The paraffin-embedded specimens obtained before treatment from 173 patients were processed for immunohistochemical staining, using the monoclonal antibody NCL-EGFR (Novocastra, UK). EGFR immunostaining was considered positive if membrane staining was found in at > or = 20% of tumour cells in one or more fields at > or = 200 (area 0.59 mm2). RESULTS Most patients (149) received preoperative irradiation and one had neoadjuvant chemotherapy. The mean observation time was 81.3 months; 63 patients (36%) had tumour recurrence within 1-80 months (mean 18.3). Positive EGFR immunostaining was found in 100 patients (58%). The proportion of T2-4 tumours was higher in those EGFR-positive than in those EGFR-negative. Proportional-hazards analysis revealed that clinical stage was significantly associated with cancer-specific death, but EGFR expression was not. CONCLUSION Although positive immunostaining for EGFR was more frequent in higher stages of locally advanced bladder cancer, this variable was not an independent predictor of outcome after cystectomy.

Abstract
PURPOSE Multivariate analysis of prognostic factors influencing survival and bladder preservation after radiochemotherapy for bladder cancer following transurethral resection of the bladder (TURB). PATIENTS AND METHODS At the University Hospital of Erlangen 333 patients with bladder cancer were treated with either radiotherapy alone (RT, n = 128) or platin based radiochemotherapy (RCT, n = 205) after TURB between 5/1982 and 5/1996. Two-hundred and eighty-two curative patients, with either muscle invasive or T1-high risk cancer, were analyzed. Median age was 66 years, median follow-up is 7.5 years. Uni- and multivariate analysis was performed for age, grade, R-status after initial TURB, T-category and treatment modality relevant to the endpoints initial response, survival and bladder preservation. RESULTS Treatment related mortality was below 1%. Complete remissions were achieved at 57%, 70%, and 85% after RT or RCT with carboplatin or cisplatin. This difference was multivariately significant. Further significant prognostic factors were pT-category and R-status. For all patients survival was 59% and 43% after 5 and 10 years. 79% of survivors could keep their own bladder. Five-year survival rates after RT alone, RCT with carboplatin or cisplatin were 47%, 57%, and 69%, respectively. This was univariately significant. The only multivariately significant factor for survival and bladder preservation was the R-status after initial TURB. CONCLUSIONS Treatment of bladder cancer by TURB and RT/RCT is an alternative to primary cystectomy. The addition of chemotherapy leads to significantly more complete remissions and better survival. Initial TURB is recommended to be as radical as possible.

Abstract
PURPOSE Presently, for muscle-invasive bladder cancer, radical cystectomy is considered to be the standard treatment. Bladder preservation, in the interest of quality of life, is secondary to the primary treatment goal of curing the patient. We present a 14-year multivariate analysis of prognostic factors influencing survival and bladder preservation after transurethral resection of the bladder (TURB) and radiotherapy (RT) +/- chemotherapy. METHODS AND MATERIALS From May 1982 to May 1996, sequential cohorts of 333 patients with bladder cancer (mean age: 66 years) were treated by either RT alone (128 patients), or with platin-based concomitant radiochemotherapy (RCT, 205 patients) after TURB. Patients (282) with muscle-invasive or T1 high-risk cancers (Grade III, residual tumor after TURB, multifocality, tumor diameter > 5 cm, associated Tis or Ta, multiple recurrences or lymph node metastases), who received a minimal target dose of 45 Gy were selected for analysis (med. follow-up = 7.5 years): after October 1985, 115 patients received cisplatin (25 mg/m2) and 69 patients carboplatin (65 mg/m2) before every treatment fraction (1.8 Gy) on Days 1-5 and 29-33 of conventional fractionated RT. RESULTS Complete remission rate was 20% (55 of 282 patients) after radical TURB, 57% (56 of 98) after TURB plus postoperative RT, and 80% (145 of 181 patients) after TURB plus RCT (85% after concomitant cisplatin and 70% after RCT plus carboplatin). These differences were significant in multivariate analysis (p = 0.003-0.05). The strongest impact on initial response had T-category (p < 0.0001) and R-status after TURB (p < 0.0003). Cause-specific survival (CSS) was 59 and 43% after 5 and 10 years; 79% of patients survived with preserved bladder. Five-year CSS after RT, RCT-Cis, and RCT-Carbo was 40, 64, and 54%, 10-year CSS 31, 48, and 27%, respectively (p = 0.04-0.045, univariate). R-status after TURB was the only independent prognostic factor for survival and bladder preservation. For relapsed patients after cystectomy, the 5- and 10-year CSS were 40 and 33%. CONCLUSIONS TURB followed by RT/RCT is an alternative treatment option to primary cystectomy for patients with muscle-invading bladder cancer. Compared to historic controls, the addition of cisplatin or carboplatin leads to significantly more complete remissions and better survival. Survival rates are similar to those achieved by primary cystectomy and possibly even better for selected subjects, such as patients with T3b and T4 tumors. Cystectomy should be restricted to only those patients who fail after RCT.

Abstract
PURPOSE To evaluate the results of transurethral resection (TUR), external beam radiotherapy (EBRT), and interstitial radiation (IRT) with iridium-192, using the afterloading technique in patients with muscle invasive bladder cancer. METHODS AND MATERIALS From May 1989 until September 1995, 66 patients with primary, solitary muscle invasive bladder cancer were treated with TUR, EBRT, and IRT, aiming at bladder preservation. According to the protocol, in three patients low-dose EBRT was applied, whereas 63 patients received high-dose EBRT. Immediately prior to IRT, 42 patients underwent a lymphnode dissection, and in 16 cases a partial cystectomy was performed. For IRT, two to five catheters were used and IRT was started within 24 h after surgery. The majority of patients received 30 Gy of IRT, with a mean dose rate of .58 Gy/h. In three patients, additional EBRT was applied following IRT. Follow-up consisted of regular cystoscopies, mostly done during joint clinics of urologist and radiation oncologist, with urine cytology routinely performed. The median follow-up period was 26 months. The Kaplan-Meier method was used for the determination of survival rates. RESULTS In seven patients, a bladder relapse developed. The probability of remaining bladder relapse free at 5 years was 88%. The bladder was preserved in 98% of the surviving patients. Metastases developed in 16 patients, and the probability of remaining metastasis free at 5 years was 66%. The cumulative 5-year overall and bladder and distant relapse free survival were 48% and 69%, respectively. Acute toxicity was not serious in the majority of cases; surgical correction of a persisting vesicocutaneous fistula was necessary in two patients, whereas a wound toilet had to be performed in another patient. Serious late toxicity (bladder, RTOG Grade 3) was experienced by only one patient. CONCLUSIONS Interstitial radiation preceded by TUR and EBRT, in a selected group of patients with muscle invasive bladder cancer, yields an excellent bladder tumor control rate with a high probability of bladder preservation. Survival was mainly dependent on the development of distant metastases. Serious acute and late toxicity was rare.

Abstract
PURPOSE The role of preoperative radiotherapy for patients with muscle-invasive bladder cancer remains controversial. Since 1985, the primary modality for treatment of these patients at our institution has been radical cystectomy alone. Prior to that time, the use of preoperative and cystectomy had been the mainstay of treatment. In this retrospective review we compare the results of these treatments, focusing on local control. METHODS AND MATERIALS The preoperative radiotherapy and radical cystectomy (PREOP) group was comprised of 338 patients with muscle-invasive (Stages T2-T4) transitional cell carcinoma of the bladder treated between 1960 and 1983. A mean total dose of 49.3 +/- 0.2 Gy (+/- SE) was administered at 2 Gy per fraction 4-6 weeks prior to cystectomy. The radical cystectomy alone (CYST) group was comprised of 232 patients treated between 1985 and 1990. The median follow-up for the PREOP group was 91 months and for the CYST group was 54 months. Only those patients who completed planned PREOP (n = 301) and CYST (n = 220) treatments were included in the analyses described below. RESULTS The treatment groups were stratified by clinical stage and compared in terms of actuarial local control. There were no differences between the groups for Stage T2 or T3a patients, and there were not enough Stage T4 patients in the PREOP group with which to make a meaningful comparison. However, for those with T3b disease, actuarial 5 year local control for the PREOP group (n = 92) was 91%, compared to 72% for the CYST group (n = 43). This difference was significant at p = 0.003 (log rank). Patients with T3b disease who received PREOP also fared slightly better at 5 years in terms of freedom from distant metastasis (67% vs. 54%), disease freedom (59% vs. 47%), and overall survival (52% vs. 40%); although, these differences did not reach statistical significance. The distribution of prognostic factors in the groups was analyzed to determine if this could account for the differences in local control in Stage T3b patients. For patients with Stage T3b disease, the only significant difference was by grouped age (p < 0.05, chi-square), which was not a significant factor in the univariate analyses of local control. A multivariate analysis using Cox proportional hazards models revealed pretreatment hemoglobin, blood urea nitrogen (BUN) concentration, and treatment type (PREOP vs. CYST) to be independently predictive of local control. CONCLUSION We document here in a large number of patients treated at a single institution that preoperative radiotherapy had a significant impact on local control for patients with clinical Stage T3b disease. Because the CYST patients were treated using modern-day surgical techniques and 80% of those with Stage T3b disease received multiagent chemotherapy, it is probable that any biases, if present, would favor the CYST group. Thus, the differences between PREOP and CYST described may be underestimated. Preoperative radiotherapy should be considered as an adjunct to chemotherapy and surgery for clinical Stage T3b patients.

Abstract
OBJECTIVES Because repetitive hematuria home screening with a chemical reagent strip can detect early stage bladder cancer (BC) in asymptomatic middle-aged and elderly men, the ability of this screening to effect earlier detection and reduce BC mortality was investigated. METHODS Grades, stages, and outcomes of BCs detected by hematuria screening in 1575 men were compared with those of all newly diagnosed BCs in men age 50 years or older reported to the Wisconsin cancer registry in 1988. BC grades and stages were assigned by review of all pathology slides/blocks, and causes of deaths were determined from cancer registry records. As an additional control group, outcomes of BC cases diagnosed in men solicited to take part in screening, who declined, were also determined. RESULTS The proportions of low-grade (grades 1 and 2) superficial (Stages Ta and T1) versus high-grade (grade 3) or invasive (Stage T2 or higher) cancers in cases detected by hematuria screening (screened cases) and those reported to the tumor registry (unscreened cases) were not significantly different (52.4% versus 47.7% in 21 screened and 56.8% versus 43.3% in 511 unscreened cases) (P > 0.20). Of the high-grade or invasive cases, however, the proportion of late stage (T2 or higher) tumors was significantly lower in the screening-detected BCs compared to unscreened ones (P = 0.007). No screened case has died of BC (3- to 9-year follow-up), whereas 16.4% of unscreened cases have within 2 years of diagnosis (P = 0.025). Twenty-three of 1940 (1.2%) men who were solicited but chose not to participate in screening were diagnosed with BC within 18 months after what would have been their last home screening date, compared with 1.3% of participants having BC detected by screening. Thus, screening participants and those who were solicited and declined had similar likelihoods of developing BC. CONCLUSIONS Hematuria home screening detects high-grade cancers before they become muscle invading and significantly reduces BC mortality.

Abstract
BACKGROUND This study was performed to determine the importance of various potential prognostic factors in a large cohort of patients with transitional cell carcinoma of the bladder who were treated relatively uniformly at a single institution. METHODS Between 1960 and 1983, 338 patients with muscle-invasive bladder carcinoma received preoperative radiotherapy (50 Gy in 25 fractions) followed 4-6 weeks later with radical cystectomy. Lymph node sampling was performed only when suspicious adenopathy was encountered. Ninety-eight percent of the patients completed the treatment as planned. The median followup for those living was 90 months. RESULTS Actuarial 5-year pelvic control, disease free, and overall survival rates were 84, 51, and 44%, respectively, for all patients, and 88, 58, and 50%, respectively, for those who treatment completed. The overwhelming majority of failures were from distant metastases (43% at 5 years). The pathologic complete response rate was 42%, and downstaging was seen in 65% of the patients. Univariate actuarial analyses revealed clinical stage, clinical perivesical extension, tumor size, pretreatment hemoglobin level, pretreatment blood urea nitrogen (BUN) concentration, results of intravenous pyelography, sex, age, pathologic response, and pathologic complete response, correlated with disease outcome. A Cox proportional hazards model showed pathologic response (P < 0.0001), clinical stage (P = 0.01), hemoglobin level (P < 0.02), pathologic complete response (P < 0.05), and BUN concentration (P < 0.05), were correlated significantly with pelvic control. When only pretreatment factors were analyzed, clinical stage, hemoglobin level, and BUN concentration remained the only factors predictive of pelvic control. Similar results were obtained when overall survival was used as the endpoint, except that pathologic complete response and BUN concentration were replaced by sex as significant covariates. A Cox proportional hazards model using disease free status as the endpoint revealed pathologic response and tumor size to be independent predictors of patient outcome. Restricting this analysis only to pretreatment factors showed that pretreatment hemoglobin and tumor size were the only factors correlated with disease free status. CONCLUSIONS The most significant prognostic factor was pathologic response, which correlated highly with all disease endpoints investigated. The most consistently significant pretreatment factors were hemoglobin level and clinical stage, although tumor size, sex, and BUN concentration also were independent predictors of patient outcome. These factors should be considered in patients receiving radiotherapy for bladder preservation.

Abstract
The definitive diagnosis of bladder cancer is established at cystoscopic examination and confirmed by means of a transurethral biopsy. A careful bimanual palpation of the bladder under anesthesia is an integral part of the initial assessment of each patient. The most important part of the assessment of patients with bladder cancer is a thorough pathologic examination of the biopsy material establishing the histologic type of tumor, histologic grade, tumor configuration, depth of invasion of the bladder wall, and depth of the bladder wall available for assessment. If possible, the size of the tumor and the presence of associated carcinoma in situ should also be reported. Imaging studies play a smaller role in the clinical staging of bladder cancer. However, when initial staging procedures point to invasion of the muscularis propria, chest X-ray, bone scan, and computed tomography scan of the abdomen and pelvis may provide valuable information about possible metastases. Whereas the clinical staging is essential to select and evaluate therapy, the pathologic stage (pTNM) provides the most precise data with which to estimate prognosis and calculate end results. The pathologic assessment entails resection of the primary tumor or a biopsy adequate to evaluate the highest pT category, removal of lymph nodes adequate to validate the absence of regional lymph node metastasis, as well as biopsy and microscopic examination for assessment of distant metastases. Although numerous factors have an impact on the behaviour of the malignancy, in bladder cancer the anatomic extent of disease reflected in the current staging classification remains the most powerful indicator of outcome.

Abstract
Over the past 20 years, advances in tumor staging, tumor biology, and therapeutic management have positively influenced both cure rates and overall survival of patients with bladder cancer. Treatment recommendations depend on the stage of the disease, the grade of tumor, likelihood of recurrence, and the patient's medical condition. These patients continue to be faced with treatment options that affect their physical, sexual, and psychosocial well-being.

Abstract
Staging of bladder tumors is based primarily on the depth of tumor invasion (T-category). Stage is important to treatment planning and prognosis. The problem is that clinical evaluation by T-category alone often understages the pathologic extent of disease and does not reliably predict treatment results. The current analysis shows that the presence of a mass palpable on bimanual examination is of prognostic value. Incorporating tumor volume with microscopic tumor invasion may enhance the usefulness of clinical staging.
