Abstract
In metastatic urothelial cancer (mUC), cisplatin versus carboplatin leads to durable disease control in a subset of patients. The IMvigor130 trial reveals more favorable effects with atezolizumab combined with gemcitabine and cisplatin (GemCis) versus gemcitabine and carboplatin (GemCarbo). This study investigates the immunomodulatory effects of cisplatin as a potential explanation for these observations. Our findings indicate that improved outcomes with GemCis versus GemCarbo are primarily observed in patients with pretreatment tumors exhibiting features of restrained adaptive immunity. In addition, GemCis versus GemCarbo ± atezolizumab induces transcriptional changes in circulating immune cells, including upregulation of antigen presentation and T cell activation programs. In vitro experiments demonstrate that cisplatin, compared with carboplatin, exerts direct immunomodulatory effects on cancer cells, promoting dendritic cell activation and antigen-specific T cell killing. These results underscore the key role of immune modulation in cisplatin's efficacy in mUC and highlight the importance of specific chemotherapy backbones in immunotherapy combination regimens.

Abstract
INTRODUCTION Urinary bladder cancer is a frequent neoplasia in the urogenital system. Ageing and smoking are the two main risk factors, however, some chemical agents such as artificial sweeteners could act as initiators or promoters. EVIDENCE ACQUISITION After identifying trends in scientific literature, we conducted a wide search in PubMed database and a meta-analysis was performed on extracted data to determine the role of artificial sweeteners in the development of urinary bladder cancer. EVIDENCE SYNTHESIS Twenty-one full reports were enrolled from screening of PubMed database into final analysis involving 116,568 subjects in comparisons. Overall, 13,682 and 102,886 cases were identified for bladder cancer patients and healthy controls, respectively. Among artificial sweetener users, 12.5% was the incidence of bladder cancer. In the control group, 11.2% of cases suffered from urothelial carcinoma of the bladder. About 40.7% of the patients suffering from urinary neoplasms and 37.8% of the healthy cases were artificial sweetener users, respectively. There were only minor differences in overall descriptive data. The incidence of urinary bladder cancer among artificial sweetener users and control cases showed no risk difference (RD: 0.00, CI: -0.06 to 0.06). The frequency of artificial sweetener use among patients suffering from urinary bladder neoplasms and healthy subjects was compared which showed equal occurrences (OR: 0.96, CI: 0.79 to 1.17). CONCLUSIONS According to our results, the carcinogenic risk of artificial sweeteners is not proven. Saccharin should not be kept as a promoter in urothelial malignant transformation.

Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) are effective strategies for multiple cancers and may be safe in people living with HIV (PLWH). Camrelizumab is a monoclonal antibody against PD-1 activating T cells against tumor cells. Evidence of camrelizumab's safety and activity in PLWH with urothelial carcinoma (UC) is lacking. Here, findings in a cohort of people living with HIV with advanced or metastatic urothelial carcinoma are presented. METHODS Patients who had locally advanced or metastatic disease after radical surgery were given camrelizumab (200 mg intravenously every 3 weeks). The primary endpoint was objective response per Response Evaluation Criteria in Solid Tumors version 1.1. The second endpoint was adverse events after treatment. RESULTS In total, nine patients were included in this study with a median follow-up of 6.2 months (4.1-20.5). The objective response rate achieved 55%. Tumor response comprised 2 (22%) complete responses and 3 (33%) partial responses. The median of progression-free survival was 6.2 months (95% CI, 9.83-20.63). Only two grade 3 adverse reactions were reported (no toxic deaths or immune-related deaths). CONCLUSION Camrelizumab showed potent antitumor activity and acceptable safety in PLWH with advanced or metastatic urothelial carcinoma.

Abstract
PurposeAristolochic acid (AA) is a carcinogen in upper urinary tract urothelial carcinoma (UTUC). This study investigated the latency period between AA exposure and UTUC development.Materials and methodsThis population-based cohort study was designed using record linkage of the National Health Insurance Research Database (NHIRD), Taiwan Cancer Registry Dataset, and cause-of-death data in Taiwan. Those aged 40–79 years were enrolled in this study. Patients who died or had renal insufficiency or UTUC before 2005 were excluded. The doses of AA exposure and rates of comorbidities between 2000 and 2005 were obtained. The Cox proportion hazard model was used to estimate the risk of UTUC between 2005 and 2016. In addition, the Cox model with time-varying coefficient of AA was used to measure the latency period of UTUC.ResultsOf the 752,232 participants enrolled from the NHIRD, 520,871 (68.29%), 210,447 (27.59%), and 31,415 (4.12%) were exposed to cumulative AA doses of 0–1 mg, 1–150 mg, and >150 mg, respectively. A total of 1,147 (0.15%) patients were diagnosed with UTUC between 2005 and 2016. The latency periods of UTUC in middle-aged (40–59 years old) men with cumulative AA doses of 1–150 mg and middle-aged women with cumulative AA doses of 1–150 mg and >150 mg were 8, 9, and 7 years, respectively. Among the aged (60–79 years) individuals, no time-varying effect was observed, and the latency period could not be measured.ConclusionA decreased risk of UTUC was observed after the ban on AA in Taiwan, especially in middle-aged women with moderate to high doses of AA exposure and men with moderate doses of AA exposure. The latency period of UTUC varies with age, the dose of AA exposure, and sex.

Abstract
BACKGROUND The association of concurrent proton pump inhibitor (PPI) use with treatment outcome of metastatic urothelial carcinoma (UC) remains controversial. MATERIALS AND METHODS We retrospectively analyzed the records of 227 patients with platinum-treated metastatic UC treated with pembrolizumab. The primary outcome was overall survival (OS). Immune progression-free survival (iPFS) and objective response per immune response evaluation criteria in solid tumors were also compared. Inverse probability of treatment weighting (IPTW)-adjusted multivariable Cox regression models and an IPTW-adjusted multivariable logistic regression model were used to evaluate the oncological outcomes. Furthermore, the heterogeneity of the treatment effect on OS was examined using interaction terms within the IPTW-adjusted univariate Cox regression models. RESULTS Overall, 86 patients (37.9%) used PPIs. After weighting, no significant differences in patient characteristics were observed between PPI users and non-users. PPI use was significantly associated with a shorter OS (hazard ratio [HR]: 2.02, 95% confidence interval [CI]: 1.28-3.18, P = 0.003) and iPFS (HR: 1.70, 95% CI: 1.23-2.35, P = 0.001). Although not statistically significant, PPI use was associated with objective response as well (OR: 0.61, 95% CI: 0.36-1.02, P = 0.06). The interaction analyses showed that the effect of PPI significantly decreased with age (HR: 0.97, 95% CI: 0.93-1.00, P[interaction] = 0.048) and was increased in males (HR: 2.97, 95% CI: 1.10-8.05, P[interaction] = 0.032). CONCLUSIONS PPI use was significantly associated with worse survival of patients with metastatic UC treated with pembrolizumab. Furthermore, the results suggested that its effects decreased with age and was increased in males.

Abstract
Recurrent upper tract urothelial carcinomas (UTUCs) arise in the context of nephropathy linked to exposure to the herbal carcinogen aristolochic acid (AA). Here we delineated the molecular programs underlying UTUC tumorigenesis in patients from endemic aristolochic acid nephropathy (AAN) regions in Southern Europe. We applied an integrative multiomics analysis of UTUCs, corresponding unaffected tissues and of patient urines. Quantitative microRNA (miRNA) and messenger ribonucleic acid (mRNA) expression profiling, immunohistochemical analysis by tissue microarrays and exome and transcriptome sequencing were performed in UTUC and nontumor tissues. Urinary miRNAs of cases undergoing surgery were profiled before and after tumor resection. Ribonucleic acid (RNA) and protein levels were analyzed using appropriate statistical tests and trend assessment. Dedicated bioinformatic tools were used for analysis of pathways, mutational signatures and result visualization. The results delineate UTUC-specific miRNA:mRNA networks comprising 89 miRNAs associated with 1,862 target mRNAs, involving deregulation of cell cycle, deoxyribonucleic acid (DNA) damage response, DNA repair, bladder cancer, oncogenes, tumor suppressors, chromatin structure regulators and developmental signaling pathways. Key UTUC-specific transcripts were confirmed at the protein level. Exome and transcriptome sequencing of UTUCs revealed AA-specific mutational signature SBS22, with 68% to 76% AA-specific, deleterious mutations propagated at the transcript level, a possible basis for neoantigen formation and immunotherapy targeting. We next identified a signature of UTUC-specific miRNAs consistently more abundant in the patients' urine prior to tumor resection, thereby defining biomarkers of tumor presence. The complex gene regulation programs of AAN-associated UTUC tumors involve regulatory miRNAs prospectively applicable to noninvasive urine-based screening of AAN patients for cancer presence and recurrence.

Abstract
The adverse events of immune checkpoint inhibitors (ICIs) are mostly immune mediated reactions. In this study, we presented a patient who developed coexisting of myasthenia gravis, myocarditis and anemia after treatment with nivolumab only 1 cycle for ureteral epithelial cancer. A 66-year-old woman was admitted to our department with the complaint of recurrent hematuria and backache for 2 months. This patient was diagnosed with stage IV, T4N3M1, urothelial carcinoma of the right kidney. She received immune checkpoint therapy consisting of nivolumab. Then, the physical and neurological examination found the ptosis of eyes especially the right eye and weakness of proximal limb muscles. Patient presented with sub-sternal chest discomfort, shortness of breath, electrocardiograms suggested atrial fibrillation and possible acute myocardial ischemic. One week later, this patient died of ventricular arrhythmia. This patient has increased clinical awareness by indicating that the immune-related adverse events (irAEs) could simultaneously involve multiple systems and progress quickly. Early recognition of aberrant immune activation and complete evaluation upon the occurrence of irAEs are critical.

Abstract
Background: Arsenic is a toxic metalloid element widely distributed throughout the environment. Arsenic contaminated water has become an ongoing public health issue affecting hundred million people worldwide. The aim of this paper was to summarize the evidence in the association between arsenic metabolites and urinary tract cancer risk. Methods: A systematic review was conducted searching for observational studies that evaluated the association of arsenic metabolites and urinary tract cancer. Risk estimates from individual studies were pooled by using random effects models. Results: All the metabolites considered in this study resulted to be significantly associated to urothelial cancer, respectively: IA% 3.51 (1.21-5.82) (p = 0.003), MMA with WMD = 2.77 (1.67-3.87) (p < 0.001) and DMA with WMD = -4.56 (-7.91-1.22) (p = 0.008). Conclusions: Arsenic metabolites are significantly associated to urothelial cancer. Future studies will help to verify the independent association(s) between arsenic metabolites and urothelial cancer.

Abstract
The bladder is an important organ for the storage of excreted water and metabolites. If metabolites with carcinogenic characteristics are present in urine, the urothelial lining of the bladder could be damaged and genetically altered. In this study, we analyzed the interaction of arsenic and N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) on mouse bladder carcinogenesis. Our previous study found that arsenic affects BBN-altered urothelial enzymatic activity, protein expression, DNA oxidation and global DNA CpG methylation levels. In this study, two mouse models were used. First, after administering a co-treatment of BBN and arsenic for 20 weeks, BBN alone led to a urothelial carcinoma formation of 20%, and arsenic promoted a BBN-induced urothelial carcinoma formation of 10%. The protein expression of GSTM1, GSTO1, NQO1, and p21 did not change by arsenic along with the BBN co-treatment, but the Sp1 expression increased. In the second mouse model, BBN was a pretreatment promoter; arsenic dose-dependently deteriorated BBN-promoted dysplasia by 10% and 40% at 10 ppm and 100 ppm, respectively. Conversely, BBN pretreatment also accelerated arsenic-induced dysplasia by 30%. The urothelial carcinogenic effect reversed after ceasing BBN for a period of 20 weeks. In summary, three conclusions were drawn from this study. The first is the mutual promotion of arsenic and BBN in bladder carcinogenesis. Second, arsenic dosages without bladder carcinogenicity (10 ppm) or with slight carcinogenicity (100 ppm) promote BBN-induced mice bladder cancer progression. Finally, the dysplastic urothelium had reverted to near-normal morphology after ceasing BBN intake for 20 weeks, providing a good suggestion for people who want to quit smoking.

Abstract
Urothelial carcinoma of the bladder is a common malignancy ranked 9th with an estimated 356,600 new cases diagnosed annually worldwide. The study showed the protective effects of Lupeol in N-Butyl-N-(4-hydroxybutyl) nitrosamine induced bladder carcinogenesis in in vivo experimental model. Forty male healthy wistar rats were selected randomly divided into four groups. Group I rats served as healthy control. Group II rats were treated with BBN (150 mg/gavage/twice a week) for 8 weeks. Group III rats were treated with BBN + Lupeol [ Lupeol (50 mg/kg bw/day) treatment was started 1 week prior to the BBN treatment, and it was orally administered for 8 weeks]. Group IV rats were treated with Lupeol alone (50 mg/kg bw/day) for 8 weeks. All the experimental rats were maintained and euthanized at 32nd week. Serum and bladder tissues were collected and examined for biochemical parameters, serum markers and histopathological evaluation. Preventive (BBN + Lupeol) group modulates the activity of antioxidant enzymes such as Superoxide dismutase, Catalase, Reduced glutathione, Glutathione Peroxidase, Thiobarbituric acid reactive substances (TBARS) and drug metabolizing enzymes such as Cytochrome P450, Cytochrome b5, NADPH Cytochrome c reductase, NADPH- Quinone Oxidoreductase 1 and Glutathione-S-transferase when compared to BBN treated rats. Serological markers such as Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) were significantly (P&#60;0.05) decreased in preventive lupeol treated groups. Lupeol supplementation protects BBN induced bladder carcinogenesis in experimental rats by its antioxidant, anti-inflammatory and antiproliferative properties.

Abstract
Bladder cancer represents a significant human tumor burden, accounting for about 7.7% and 2.4% of all cancer cases in males and females, respectively. While men have a higher risk of developing bladder cancer, women tend to present at a later stage of disease and with more aggressive tumors. Previous studies have suggested a promotional role of androgen signaling in enhancing bladder cancer development. To directly assess the role of androgens in bladder tumorigenesis, we have developed a novel transgenic mouse strain, R26hARLoxP/+:Upk3aGCE/+, in which the human AR transgene is conditionally expressed in bladder urothelium. Intriguingly, both male and female R26hARLoxP/+:Upk3aGCE/+ mice display a higher incidence of urothelial cell carcinoma (UCC) than the age and sex matched control littermates in response to the carcinogen, N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN). We detect expression of the human AR transgene in CK5-positive and p63-positive basal cells in bladder urothelium. Further analyses of UCC tissues from R26hARLoxP/+:Upk3aGCE/+ mice showed that the majority of tumor cells are of urothelial basal cell origin. Positive immunostaining of transgenic AR protein was observed in the majority of tumor cells of the transgenic mice, providing a link between transgenic AR expression and oncogenic transformation. We observed an increase in Ki67 positive cells within the UCC lesions of transgenic AR mice. Manipulating endogenous androgen levels by castration and androgen supplementation directly affected bladder tumor development in male and female R26hARLoxP/+:Upk3aGCE/+ mice, respectively. Taken together, our data demonstrate for the first time that conditional activation of transgenic AR expression in bladder urothelium enhances carciongen-induced bladder tumor formation in mice. This new AR transgenic mouse line mimics certain features of human bladder cancer and can be used to study bladder tumorigenesis and for drug development.

Abstract
B6C3F1 mice chronically exposed to 3,3',4,4'-tetrachloroazobenzene (TCAB), a contaminant of dichloroaniline-derived herbicides, developed a number of neoplastic and nonneoplastic lesions, including carcinoma of the urinary tract. Groups of fifty male and fifty female B6C3F1 mice were exposed by gavage to TCAB at dose levels of 0, 3, 10, and 30 mg/kg five days a week for two years. Control animals received corn oil:acetone (99:1) vehicle. Decreased survival of male mice in the mid-dose group and of male and female mice in the high-dose groups was related mainly to the occurrence of urethral transitional cell (urothelial) carcinoma and resulting urinary obstruction. Increased urethral transitional cell carcinomas were seen in all treated male groups in a dose-related manner as well as in the females treated with 30 mg/kg TCAB. Administration of TCAB was also associated with increased transitional cell hyperplasia of the urethra. Most nonneoplastic lesions of the urogenital tract were considered secondary to local invasion and urinary obstruction by the urethral transitional cell carcinomas. The mechanism of tumor induction is uncertain, but the high frequency of tumors in the proximal urethra of male mice suggests that the neoplasms result from the exposure of a susceptible population of urothelial cells to a carcinogenic metabolite of TCAB.

Abstract
A 26-year-old-woman was given a diagnosis of Wegener's granulomatosis and began treatment by both prednisolone and cyclophosphamide at another institution. She was then admitted to our hospital due to progressive multiple pulmonary nodules. A diagnosis of pulmonary metastases from bladder cancer was established with radiological and histological examinations obtained by transbronchial lung biopsy (TBLB) and transurethral resection of the bladder tumor (TUR-Bt). She had already received a total dose of 120 g of cyclophosphamide, which could be related to the development of bladder cancer. On detecting multiple pulmonary nodules in patients with Wegener's granulomatosis treated with cyclophosphamide, it is necessary to consider the possibility of pulmonary metastases form urinary bladder cancer.

Abstract
Cigarette smoking is the most important risk factor for development of transitional cell carcinoma of the urinary bladder. The effect of polymorphisms of glutathione S-transferases M1 (GSTM1) and M3 (GSTM3) on the influence of cigarette smoking on urinary bladder carcinogenesis was investigated. In total, 293 bladder cancer patients from hospitals in Dortmund and Wittenberg as well as 176 patients without any malignancy from a Department of Surgery from Dortmund were genotyped for GSTM1 and GSTM3 according to standard PCR/RFLP methods. Smoking habits were quantified by a standardized interview. The proportion of GSTM1 negative cases was 63% in the entire bladder cancer cases group compared to 50% in controls. The GSTM3*A/*A genotype was 76% in cancer cases versus 74% in controls. Smokers and ex-smokers were overrepresented in bladder cancer cases. A significant association between smoking status and GSTM1 or GSTM3 genotype was not detected. The elevated proportion of GSTM1 negative bladder cancer cases shows an effect of this polymorphic enzyme on development of bladder cancer. In contrast to other studies, an influence of GSTM1 on the risk due to cigarette smoking was not observed.

Abstract
Our work has focused on the carcinogenic effects of in utero arsenic exposure in mice. Our data show that a short period of maternal exposure to inorganic arsenic in the drinking water is an effective, multi-tissue carcinogen in the adult offspring. These studies have been reproduced in three temporally separate studies using two different mouse strains. In these studies pregnant mice were treated with drinking water containing sodium arsenite at up to 85 ppm arsenic from days 8 to 18 of gestation, and the offspring were observed for up to 2 years. The doses used in all these studies were well tolerated by both the dam and offspring. In C3H mice, two separate studies show male offspring exposed to arsenic in utero developed liver carcinoma and adrenal cortical adenoma in a dose-related fashion during adulthood. Prenatally exposed female C3H offspring show dose-related increases in ovarian tumors and lung carcinoma and in proliferative lesions (tumors plus preneoplastic hyperplasia) of the uterus and oviduct. In addition, prenatal arsenic plus postnatal exposure to the tumor promoter, 12-O-tetradecanoyl phorbol-13-acetate (TPA) in C3H mice produces excess lung tumors in both sexes and liver tumors in females. Male CD1 mice treated with arsenic in utero develop tumors of the liver and adrenal and renal hyperplasia while females develop tumors of urogenital system, ovary, uterus and adrenal and hyperplasia of the oviduct. Additional postnatal treatment with diethylstilbestrol or tamoxifen after prenatal arsenic in CD1 mice induces urinary bladder transitional cell proliferative lesions, including carcinoma and papilloma, and enhances the carcinogenic response in the liver of both sexes. Overall this model has provided convincing evidence that arsenic is a transplacental carcinogen in mice with the ability to target tissues of potential human relevance, such as the urinary bladder, lung and liver. Transplacental carcinogenesis clearly occurs with other agents in humans and investigating a potential transplacental component of the human carcinogenic response to arsenic should be a research priority.

Abstract
OBJECTIVES Carcinogen-induced bladder cancer in rodents is a key model for evaluation of novel therapies for bladder cancer because of its similarity to the clinical disease. The major drawback of the model is the difficulty in assessing tumor burden in living animals and at necropsy. The objective of this work was to present simple and accurate solutions for this problem. METHODS Sixty female Wistar rats were given N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN) at a concentration of 0.05% in the drinking water for 35 weeks. Periodic evaluation of tumorigenesis was done by ultrasonography of the anesthetized animals. The tumor burden was evaluated after killing the rats by weighing the bladder, digital measurement of the tumor dimensions, and histologic examination. RESULTS Focal urothelial hyperplasia was noted by the 5th BBN week, severe dysplasia by the 15th BBN week, and transitional cell carcinoma from the 20th week on. Carcinoma was seen on digital photographs taken from the 20th week on. Tumors as small as 1 mm could be easily measured. A poor correlation (R2 = 0.33) was found between bladder weight and the digital photographic measurements of small tumors (20th BBN week). However, when larger tumors were considered (30th BBN week), a good correlation was found (R2 = 0.81). CONCLUSIONS Tumor progress in the rat BBN model was accurately monitored by ultrasonography in living animals. Digital measurement of tumor dimensions provided a precise method for evaluation of tumor burden at necropsy.

Abstract
To investigate the prostaglandin E2 (PGE2) biosynthetic mechanism in bladder carcinogenesis, we established Wistar rat model of bladder papilloma and transitional cell carcinoma (TCC) induced by 5% terephthalic acid (TPA) treatment. Then, the mRNA level of cytosolic phospholipase A2 (cPLA2), cyclooxygenases (COX)-1 and -2, membrane-bound PGE2 synthases (mPGES)-1 and -2 was detected using reverse transcription polymerase chain reaction (RT-PCR). Immunoblotting was applied to detect the expression of COX-2 protein. Proliferating cell nuclear antigen (PCNA) was determined by immunohistochemistry. In addition, the level of PGE2 was measured by radioimmunoassay (RIA). Bladder papilloma (100%, 8/8) was examined in rats after 24-week treatment, and bladder TCC (80%, 16/20) was found after 48-week treatment. Histopathological changes were not found in control group rats. The incidence of bladder papilloma and TCC in test group was significantly higher than that in control group (P<0.01). The mRNA levels of cPLA2, COX-2 and mPGES-1 in the bladder papilloma and TCC were significantly higher than those in normal bladder (P<0.01), while the mRNA levels of COX-1 and mPGES-2 in TCC were unchanged compared with normal bladder. Bladder TCC exhibited a substantial expression of COX-2 protein. On the contrary, normal bladder tissue barely expresses COX-2 protein. PCNA labeling index (LI) and the level of PGE2 in bladder papilloma are much higher than those in normal bladder (P<0.01), but lower than those in bladder TCC (P<0.05). In conclusion, increasing PGE2 level via cPLA2--COX-2--mPGES-1 pathway may play an important role in rat bladder carcinogenesis. PGE2 may be a biomarker for the development of bladder TCC. cPLA2 and mPGES-1 may be targets for development of novel chemoprevention strategies for bladder TCC.

Abstract
Mate is a 'tea', made from Ilex paraguariensis, widely consumed in South America, as mate con bombilla and mate cocido. Mate consumption has been associated with esophageal, oral, lung, and bladder cancers. This bladder cancer case-control study involved 114 Argentinean case-control pairs. Mate consumption was recorded for time of interview, and 20 and 40 years previously. Mate con bombilla consumed 20 years ago was associated with bladder cancer in ever-smokers (odds ratio=3.77, 95% confidence interval: 1.17-12.1), but not in never-smokers. Mate cocido was not associated with bladder cancer. These results are consistent with a previous study in Uruguay.

Abstract
OBJECTIVE To examine the chemopreventive effects of a selective cyclooxygenase (COX)-2 inhibitor, meloxicam, and a selective epidermal growth factor (EGF)-receptor tyrosine kinase inhibitor, gefitinib (as a single agent) on a carcinogen-induced rodent bladder carcinogenesis model. MATERIALS AND METHODS The study comprised 103 male Fisher-344 rats (8 weeks old); after initial carcinogen treatment for 8 weeks with 0.05%N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) in drinking water, the rats were divided into five groups, i.e. group 1, control (vehicle only); group 2, gefitinib high-dose (15 mg/kg by gavage once daily); group 3, gefitinib low-dose (5 mg/kg); group 4, meloxicam high-dose (1.8 mg/kg by gavage once daily); and group 5, meloxicam low-dose (0.6 mg/kg). Twelve weeks later the rats were killed; after fixing the bladder in 10% formalin, the number and size of hyperplasia and carcinoma foci were recorded microscopically in sections stained with haematoxylin and eosin, submitted entirely as multiple strips. RESULTS The incidence of carcinoma, confirmed microscopically, was: control 14/20 (70%); high-dose gefitinib, 7/20 (35%); low-dose gefitinib, 7/20 (35%); high-dose meloxicam 7/21 (33%); and low-dose meloxicam, 12/20 (60%). The mean numbers of carcinomas per bladder in groups 1-5 were 1.2, 0.5, 0.4, 0.5 and 1.1, respectively. The incidence and the mean number of carcinomas per bladder were significantly lower in the treatment groups (P < 0.05) than in the control group, except in the low-dose meloxicam group. There were no significant adverse effects. CONCLUSION Both meloxicam and gefitinib have inhibitory effects on rat bladder carcinogenesis with no significant adverse effects. A combination of these drugs would be worth studying for their synergistic effects.

Abstract
OBJECTIVES Transitional cell carcinoma of the urinary bladder is associated with occupational exposure to 4,4'-methylenebis(2-chloroaniline) (MBOCA). A program to monitor MBOCA levels in the work environment and to screen for bladder cancer was performed at four MBOCA manufacturing factories. METHODS The U.S. Occupational Safety and Health Administration analytic method No. 24 was adopted in this study to measure air MBOCA concentrations. A total of 70 MBOCA-exposed workers and another 92 nonexposed workers were recruited for screening. Urine occult blood tests, urine cytology, tests for the urine tumor marker nuclear matrix protein, and abdominal ultrasonography were performed in all patients. Intravenous urography and cystoscopy were used to confirm the presence of bladder cancer. RESULTS The air concentration of MBOCA was greatest in the purification area (0.23 to 0.41 mg/m3), followed by the washing area (less than 0.02 to 0.08 mg/m3) and neutralization area (less than 0.05 to 0.06 mg/m3). This study identified a current worker with proved bladder cancer. In addition, we also identified 1 worker with suspected malignant cells on urine cytology and 1 worker with atypical cytology combined with gross hematuria. Although the prevalence of atypical urinary cells and the nuclear matrix protein 22 tumor marker was not significantly different between the MBOCA-exposed workers and nonexposed workers as a whole or when grouped by sex, the prevalence of positive occult blood was marginally significantly (P = 0.055) greater in male exposed workers (18%) than in male nonexposed workers (7%). CONCLUSIONS The findings of this study support the conclusions from other studies that MBOCA is potentially carcinogenic to humans. Control measures are needed to prevent overexposure from inhalation and skin absorption.

Abstract
Technical dinitrotoluene (consisting of 2,4- and 2,6-dinitrotoluene isomers) has been widely used as explosives. Both technical isomers are mutagenic in Salmonella typhimurium TA98 strains and carcinogenic in rodents. 2,4-dinitrotoluene shows a dose-dependency of malignant tumors of the kidneys, liver, and mammary glands in rats and mice. In this case report, we discuss a cluster of three cases of urothelial cancer amongst a group of about 60 workers exposed to dinitrotoluenes. The workers were employed in the manufacturing of nitrotoluene explosives in the former German Democratic Republic. The cases occurred within a period of 12 years (1990-2002) leading to a 15.9 fold higher incidence of cancer of the urinary bladder than of the federal state where the chemical factory was located. The observation of the cluster of urothelial cancer in persons highly exposed to nitrotoluenes underlines the putative human carcinogenicity of dinitrotoluenes with the human urothelium as a relevant target tissue.

Abstract
OBJECTIVES To investigate the effect of inhibiting tumor angiogenesis during cisplatinum-(II)-diamine dichloride (cisplatin) chemotherapy of bladder cancer (BC) in a rat model. METHODS Bladder cancer was induced in 64 male rats using 0.05% N-butyl-N-(4-hydroxybutyl)-nitrosamine in their water supply for 20 weeks. The animals were then divided randomly into four groups of 16 rats each: a control BC group (group 1); a BC group treated with cisplatin (0.25 mg/kg body weight) by intraperitoneal injection twice every week (group 2); a BC group treated with the antiangiogenic factor TNP-470 (30 mg/kg body weight) by intraperitoneal injection twice every week (group 3); and a BC group treated with cisplatin plus TNP-470 (group 4, treatment regimens as described). Per group, 4 rats were killed weekly after the start of treatment, for 4 weeks. BC was confirmed using histologic characteristics, and the treatment outcomes were determined by measuring tumor microvascular density and cell proliferation and apoptosis indexes (PI and AI, respectively). RESULTS All animals had confirmed BC. Both group 3 (TNP-470) and group 4 (cisplatin plus TNP-470) had significantly decreased microvascular density compared with group 1 (P <0.05). Although both the PI and AI were significantly different between group 4 (cisplatin plus TNP-470) and group 1 (control BC; P <0.05), neither the PI nor AI was significantly different between group 2 (cisplatin) and group 4 (cisplatin plus TNP-470; P >0.05). CONCLUSIONS TNP-470 in conjunction with cisplatin chemotherapy resulted in a decrease in the microvascular density of BC in a rat model. However, TNP-470 did not appear to have a significant impact on the cisplatin effect against BC as measured by apoptosis and cell proliferation.

Abstract
PURPOSE Several occupational carcinogens are metabolized by polymorphic enzymes. The distribution of the polymorphic enzymes N-acetyltransferase 2 (NAT2; substrates: aromatic amines), glutathione S-transferase M1 (GSTM1; substrates: e. g., reactive metabolites of polycyclic aromatic hydrocarbons), and glutathione S-transferase T1 (GSTT1; substrates: small molecules with 1 - 2 carbon atoms) were investigated. MATERIAL AND METHODS At the urological department in Lutherstadt Wittenberg, 136 patients with a histologically proven transitional cell cancer of the urinary bladder were investigated for all occupations performed for more than 6 months. Several occupational and non-occupational risk factors were asked. The genotypes of NAT2, GSTM1, and GSTT1 were determined from leucocyte DNA by PCR. RESULTS Compared to the general population in Middle Europe, the percentage of GSTT1 negative persons (22.1 %) was ordinary; the percentage of slow acetylators (59.6 %) was in the upper normal range, while the percentage of GSTM1 negative persons (58.8 %) was elevated in the entire group. Shifts in the distribution of the genotypes were observed in subgroups who had been exposed to asbestos (6/6 GSTM1 negative, 5/6 slow acetylators), rubber manufacturing (8/10 GSTM1 negative), and chlorinated solvents (9/15 GSTM1 negative). CONCLUSIONS The overrepresentation of GSTM1 negative bladder cancer patients also in this industrialized area and more pronounced in several occupationally exposed subgroups points to an impact of the GSTM1 negative genotype in bladder carcinogenesis.

Abstract
A 52-year-old male chemical worker was admitted to the hospital with a history of paroxysmal microscopic hematuria for about 2 years and nocturia with gross hematuria about five times per night for 2 months. He was a nonsmoker and denied a history of any other bladder carcinogen exposure except for occasional pesticide application during agricultural work. Intravenous urogram imaging showed a mass occupying half of the bladder capacity. Cystoscopy revealed a mass over the left dome of the bladder. Cystoscopic biopsy revealed a grade 3 invasive transitional cell carcinoma with marked necrosis. From 1987 until hospital admission in 2001, the patient had worked in a company that produced the 4,4 -methylenebis(2-chloroaniline) (MBOCA) curing agent. He did not wear any personal protective equipment during work. Ambient air MBOCA levels in the purification process area (0.23-0.41 mg/m3) exceeded the U.S. Occupational Safety and Health Administration's permissible exposure level. Urinary MBOCA levels (267.9-15701.1 microg/g creatinine) far exceeded the California Occupational Safety and Health Administration's reference value of 100 microg/L. This patient worked in the purification process with occupational exposure to MBOCA for 14 years. According to the environmental and biologic monitoring data and latency period, and excluding other potential bladder carcinogen exposure, this worker was diagnosed as having occupational bladder cancer due to high exposure to MBOCA through inhalation or dermal absorption in the purification area. This case finding supports that MBOCA is a potential human carcinogen. Safe use of skin-protective equipment and respirators is required to prevent workers from MBOCA exposure.

Abstract
Transitional cell carcinoma (TCC) of the bladder in children is a rare occurrence. Cyclophosphamide is a known risk factor for the development of TCC. Other alkylating agents, such as nitrogen mustard, have not been implicated in the development of secondary adult or pediatric TCC. The role of radiotherapy in the development of secondary malignancies of the bladder remains controversial. We report a case of childhood TCC in a patient in remission from Hodgkin's lymphoma previously treated with non-cyclophosphamide chemotherapy and low-dose nodal radiotherapy.

Abstract
OBJECTIVE To evaluate the effect of nitrate levels in the drinking water on the incidence of urological malignancies in a German community. PATIENTS AND METHODS For 28 years (1957-86) the community of Bocholt, Germany (70,000 inhabitants) had a drinking water supply with different nitrate levels, i.e. 60 mg/L in group A (57,253 inhabitants) and 10 mg/L in group B (10,037 inhabitants). All newly diagnosed cases of urological malignancies were registered from 1986 to 1997. The incidence was calculated using an age standardization based on the German population. RESULTS In all, there were 527 urological malignancies recorded (urothelial cancer 39.8%, renal cell carcinoma 10.8%, testicular tumours 8.0%, penile carcinoma 1.7%, prostate cancer 39.7%). The incidence per 100,000 inhabitants/year of urinary tract tumours was 33.8 in group A and only 17.1 in group B (relative risk, RR 1.98, 95% confidence interval, CI, 1.10-3.54). The RR was 0.87 (0.34-2.22) for renal tumours, 0.66 (0.14-2.88) for penile cancer and 1.06 (0.76-1.48) for prostate cancer. For testicular tumours there was an inverse association with nitrate level, with a RR of 0.43 (0.21-0.90). CONCLUSION This study showed an association of nitrate load in drinking water and the incidence of urothelial cancer in both genders, with an inverse correlation to testicular tumours and no correlation with renal, penile and prostatic tumours.

Abstract
Carboxyamido-triazole (CAI) is an orally bioavailable calcium influx and signal transduction inhibitor that has been shown to be anti-invasive, anti-angiogenic and anti-metastatic in different human tumors including transitional cell carcinoma. This study was undertaken to further evaluate the activity of CAI in a rat bladder cancer model. A transitional cell carcinoma (TCC) was chemically induced by intravesical installation of methyl-nitrosurea (MNU) in the bladder of female Fischer 344 rats. First, a toxicity study was performed which revealed no side-effects of CAI in the animals up to a dose of 250 mg/kg CAI. For treatment, a dose of 100 mg/kg CAI dissolved in PEG-400 vehicle was chosen. Oral administration of CAI continuously daily for 4 weeks (group A), 3 days/week over 6 weeks (group B), or intravesically twice a week for 6 weeks (group C) caused a reduction of spontaneous development of TCC. Lower stage and grade of tumors were seen in all CAI-treated animals. Under CAI treatment, the apoptotic rate in tumors increased, whereas the proliferation rate decreased, as shown by TUNEL assay and KI-67-immunhistochemistry, respectively. The highest efficacy was seen in group B, with 5 out of 10 animals tumor-free. Intravesical application (group C) resulted in 3 out of 10 animals tumor-free. Normal urothelium was not affected by CAI. This animal model confirms the anti-tumor effect of CAI and shows induction of apoptosis and growth inhibition in bladder cancer by the drug.

Abstract
UDP-Glucuronyltransferase 2B7 (UGT2B7) is involved in benzidine metabolism, as demonstrated by in vitro experiments with liver slices. To evaluate the possible association of UGT2B7 gene polymorphism with bladder cancer risk for benzidine-exposed subjects, diagnosed bladder cancer cases (n = 36) who were members of a cohort of benzidine-exposed workers in the Chinese dyestuff industry were investigated. UGT2B7 polymorphism at locus C802T (His268Tyr) was detected using a PCR-RFLP based procedure. Nondiseased cohort members (156 men, 95 women) were taken as work-related control, and unexposed healthy individuals (113 men, 105 women) were taken as community control. The data showed that the polymorphism at locus UGT2B7 C802T in a general Chinese population significantly differs from that in a Caucasian population (p = 0.00018), displaying a distinctly lower frequency of T/T genotypes (9.2 vs. 25.3%), while no significant difference to a Japanese population could be detected (p = 0.17). A higher prevalence of T/T genotype carriers was found in the cancer cases, compared with unexposed healthy controls (25 vs. 9%, odds ratio [OR] 3.30, 95% confidence interval [95% CI] 1.37-7.98, p = 0.006). A higher presentation of T allele carriers in the patients group was also confirmed (46 vs. 33%, OR 1.73, 95% CI 1.05-2.87, p = 0.03). A higher portion of the T/T genotype was also observed in bladder cancer patients compared with nondiseased members of the same benzidine-exposed cohort, although some of them displayed different degrees of cellular alterations in their exfoliated urothelial cells. This study points for the first time to an association between a homozygous mutant genotype of human UDP-glucuronosyltransferase 2B7 catalyzing the biotransformation of benzidine and an elevated bladder cancer risk for formerly benzidine-exposed workers of the dyestuff industry.

Abstract
We investigated gene expression in N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN)-induced rat bladder carcinoma in order to test its applicability as a model for the study of novel therapeutic modalities, particularly gene therapy. We administered BBN in the drinking water to Wistar rats for up to 30 wk and induced papillary transitional cell carcinoma (TCC), which is similar to the most prevalent type of human bladder cancer. Tumor evolution was similar to that found in previous studies. However, we described the morphological stages according to modern human bladder carcinoma terminology. Our main goal was to examine the expression levels of the H19 gene, of the insulin-like growth factor 2 (Igf2) transcripts expressed from promoters P2 and P3 and of the telomerase subunits that we had previously investigated as tools for targeted gene therapy of bladder cancer. We detected at 30 wk of BBN exposure significant upregulation of these sequences in the rat bladder tumors, similar to our previous findings in human bladder cancer. To reinforce the similarity of this model to the corresponding human disease, we searched for additional tumor-specific genes documented as having altered expression in human bladder carcinoma, using cDNA expression arrays (Clontech). We suggest that BBN-induced rat bladder cancer has morphological, biological, and molecular parallels to human bladder cancer and is an attractive model for studying novel alternatives of therapeutic intervention.

Abstract
OBJECTIVE To determine whether use of topical flea and tick products increases the risk of transitional cell carcinoma (TCC) of the urinary bladder in Scottish Terriers. DESIGN Case-control study. ANIMALS 87 adult Scottish Terriers with TCC (cases) and 83 adult Scottish Terriers with other health-related conditions (controls). PROCEDURE Owners of study dogs were recruited through private veterinary practices and the Scottish Terrier Club of America. History of exposure to flea and tick products 1 year prior to diagnosis of TCC for case dogs and during a comparable period for control dogs was obtained through a questionnaire. Risk of TCC associated with exposure to flea and tick products was determined by means of univariate and multiple logistic regression analysis. RESULTS After adjustment for host factors, Scottish Terriers treated with topical spot-on flea and tick products containing fipronil or imidacloprid did not have an increased risk of TCC, compared with Scottish Terriers that had never been exposed to any flea and tick products. The risk of TCC associated with use of older topical flea and tick products such as shampoos, dips, powders, sprays, and collars could not be evaluated because of the low number of owners in the study population that had used such products. CONCLUSIONS AND CLINICAL RELEVANCE Results suggest that use of topical spot-on flea and tick products does not increase the risk of TCC in Scottish Terriers.

Abstract
Epidemiologic studies have demonstrated that a close association exists between the elevated levels of arsenic in drinking water and the incidence of certain cancers, including transitional cell carcinomas of the urinary bladder. We have employed in vitro and in vivo models to examine the effects of sodium arsenite on the urinary bladder epithelium. Mice exposed to 0.01% sodium arsenite in drinking water demonstrated hyperproliferation of the bladder uroepithelium within 4 weeks after initiating treatment. This occurred in the absence of amorphous precipitates and was accompanied by the accumulation of trivalent arsenite (iAs(3+)), and to a lesser extent dimethylarsenic (DMA), arsenate (iAs(5+)), and monomethylarsenic (MMA) in bladder tissue. In contrast to the bladder, urinary secretion was primarily in the form of DMA and MMA. Arsenic-induced cell proliferation in the bladder epithelium was correlated with activation of the MAP kinase pathway, leading to extracellular signal-regulated kinase (ERK) kinase activity, AP-1 activation, and expression of AP-1-associated genes involved in cell proliferation. Activation of the MAP kinase pathway involved both epidermal growth factor (EGF) receptor-dependent and -independent events, the latter involving Src activation. Studies summarized in this review suggest that arsenic accumulates in urinary bladder epithelium causing activation of specific signaling pathways that lead to chronic increased cell proliferation. This may play a non-epigenetic role in carcinogenesis by increasing the proliferation of initiated cells or increasing the mutational rate.

Abstract
N-acetyltransferase 1 (NAT1) modifies bladder cancer risk in European populations exposed to aromatic amines in cigarette smoke. The present study was performed to investigate a possible association between NAT1*10 and NAT1*14A genotypes and bladder cancer risk in benzidine-exposed Chinese workers. Based on the cytological gradings of exfoliated urothelial cells according to Papanicolaou, an exposed research cohort was stratified into subgroups. An allele-specific PCR-based procedure was used to detect the polymorphism in the polyadenylation signal at the locus NAT1 T(1088)A. A nested PCR-RFLP procedure was conducted to differentiate NAT1*14A (T(1088)A, C(1095)A, and G(560)A) from NAT1*10 (T(1088)A, C(1095)A). No significantly different frequencies of homozygous and heterozygous NAT1*10 alleles were found among the subgroups with (i) gradings according to Papanicolaou < or = II (18.3 and 40.2%, respectively), (ii) higher gradings according to Papanicolaou (> II; 28.0 and 34.1%, respectively), and (iii) with bladder cancer (26.3 and 34.2%, respectively). The present data show that NAT1*10 neither displayed an association with an elevated grading of urothelial cells nor a clear impact on the risk for bladder cancer in benzidine-exposed Chinese workers. Discrepancies with the findings in European populations could point to ethnic differences in the disposition of aromatic amines.

Abstract
OBJECTIVE To determine whether exposure to lawn or garden chemicals was associated with an increased risk of transitional cell carcinoma (TCC) of the urinary bladder in Scottish Terriers. DESIGN Case-control study. ANIMALS 83 Scottish Terriers with TCC (cases) and 83 Scottish Terriers with other health-related conditions (controls). PROCEDURE Owners of study dogs completed a written questionnaire pertaining to exposure to lawn or garden chemicals during the year prior to diagnosis of TCC for case dogs and during a comparable period for control dogs. RESULTS The risk of TCC was significantly increased among dogs exposed to lawns or gardens treated with both herbicides and insecticides (odds ratio [OR], 7.19) or with herbicides alone (OR, 3.62), but not among dogs exposed to lawns or gardens treated with insecticides alone (OR, 1.62), compared with dogs exposed to untreated lawns. Exposure to lawns or gardens treated with phenoxy herbicides (OR, 4.42) was associated with an increased risk of TCC, compared with exposure to untreated lawns or gardens, but exposure to lawns or gardens treated with nonphenoxy herbicides (OR, 3.49) was not significantly associated with risk of TCC. CONCLUSIONS AND CLINICAL RELEVANCE Results suggest that exposure to lawns or gardens treated with herbicides was associated with an increased risk of TCC in Scottish Terriers. Until additional studies are performed to prove or disprove a cause-and-effect relationship, owners of Scottish Terriers should minimize their dogs' access to lawns or gardens treated with phenoxy herbicides.

Abstract
The PATCHED (PTC) gene is recognized as a tumor suppressor in basal cell carcinoma. Mapping of a minimal region of deletion at 9q22.3 and observation of a decreased PTC expression in superficial papillary bladder tumors led us to hypothesize that it could also be involved in this cancer. To further investigate this hypothesis, we submitted Ptc(+/-) heterozygous mutant mice and their wild-type littermates to chemical carcinogenesis by adding N-butyl-N-(4-hydroxybutyl) nitrosamine to their drinking water. Preneoplastic and neoplastic changes were observed significantly earlier in the Ptc(+/-) than in the wild-type mice. Our data support the hypothesis of Ptc acting as a tumor suppressor gene in bladder cancer.

Abstract
Occupational exposure is definitely a major cause of cancer. In the field of urology, the urinary bladder is the most important target. A classical cause of bladder cancer is exposure to carcinogenic aromatic amines, especially benzidine and beta-naphthylamine. Such exposures were related to work places in the chemical industry, implying production and processing of classical aromatic amines, and in the rubber industry. Occupational bladder cancer has also been observed in dyers, painters and hairdressers. Even some occupations with much lower exposures to carcinogenic aromatic amines, like coke oven workers or workers in the rubber industry after the ban on beta-naphthylamine, are at risk. In these occupations, exposure to complex mixtures of substances containing combustion products (e.g. polycyclic aromatic hydrocarbons) or nitrosamines is common. Renal cell cancer has been observed as an occupational disease in cases of very high exposure to trichloroethylene having led to narcotic or prenarcotic symptoms. Occupationally related cancers of the prostate or the testes appear currently not relevant.

Abstract
Three cases of cyclophosphamide (CPM)-induced transitional cell carcinoma (TCC) of the bladder are reported. A 36-year-old female (case 1) and a 63-year-old male (case 2) received CPM at total doses of 104 g and 100 g, respectively, for the therapy of Wegener's granulomatosis. A 50-year-old female (case 3) received CPM at a dose of 57 g for the therapy of recurrent breast cancer. They visited our institute with the chief complaint of macrohematuria. In all cases, cystoscopy revealed bladder tumor with hemorrhagic cystitis. They underwent transurethral resection of bladder tumor. Histological examination revealed grade 2 TCC in cases 1 and 2 and grade 3 TCC in case 3. All patients underwent intravesical instillation of Mitomycin C with or without hyperthermia. Including our 3 cases, 17 cases of CPM-induced bladder tumor have been reported in the Japanese literature.

Abstract
OBJECTIVE The mechanism of arsenic detoxification in humans remains unclear. Data are especially lacking for low-level arsenic exposure. We hypothesize that arsenic methylation ability, defined as the ratios of monomethylarsonic acid (MMA(V))/inorganic arsenic (primary arsenic methylation index, PMI) and dimethylarsinic acid (DMA(V))/ MMA(V) (secondary arsenic methylation index, SMI), may modify the association between cumulative arsenic exposure (CAE, mg/L-year) and the risk of bladder cancer. In this study we investigated the relationship among arsenic methylation ability, CAE, and the risk of bladder cancer in a hospital-based case-control study in southwestern Taiwan. METHODS From January 1996 to December 1999 we identified 49 patients with newly diagnosed cases of bladder cancer at the National Cheng-Kung University (NCKU) Medical Center; controls consisted of 224 fracture and cataract patients selected from the same medical center. The levels of four urinary arsenic species: arsenite (As(III)), arsenate (As(V)), MMA(V), and DMA(V)) were determined in all subjects by using the high-performance liquid chromatography hydride-generation atomic absorption spectrometry (HPLC-HGAAS). CAE was estimated by using published data collected in a survey from 1974 to 1976. RESULTS Compared to a CAE < or = 2 mg/L-year, CAE > 12 mg/L-year was associated with an increased risk of bladder cancer (multivariate odds ratio (OR) 4.23, 95% confidence interval (CI) 1.12-16.01), in the setting of a low SMI (< or = 4.8). Compared to women, smoking men (OR 6.23, 95% CI 1.88-20.62) and non-smoking men (OR 3.25, 95% CI 0.95-11.06) had higher risks of bladder cancer. Given the same level of PMI, smoking men (OR 9.80, 95% CI 2.40-40.10) and non-smoking men (OR 4.45, 95% CI 1.00-19.84) had a higher risk of bladder cancer when compared to women. With the same level of SMI, both smoking men (OR 6.28, 95% CI 1.76-22.39) and non-smoking men (OR 3.31, 95% CI 0.84-12.97) had a higher risk of bladder cancer when compared to women. CONCLUSIONS Subjects with low SMI have a substantially increased risk of bladder cancer, especially when combined with high CAE levels.

Abstract
Correlation of development of tumor pathology and macro- and microhematuria was investigated in the experiments using 50 male rats with N-butyl-N-(4-hydroxybutyl)-nitrosoamine-induced tumors of the urinary bladder. Our highly-sensitive agent Azopiram was employed to monitor hematuria. Microhematuria, which subsequently developed into macrohematuria as tumor matured and turned malignant, was identified as early as at such incipient neoplastic changes as focal hyperplasia of the urothelium and micropapillomatosis. The test can be used outside clinic as a measure of self-control in recurrent cancer of the urinary bladder.

Abstract
Occupational exposure to arylamines in industrial settings was the first known cause of bladder cancer in humans. In the United States and many developed countries, these industrial dyes have been under strict government control for decades and are believed to contribute minimally to today's population burden of bladder cancer in the West. The two other recognized, and potentially substantial sources of human exposure to arylamines are cigarette smoking and use of hair dyes. This paper reviews the latest epidemiologic findings on the relationships between smoking, hair dye use and bladder cancer risk. Results support the notion that arylamines contained in cigarette smoke and permanent hair dyes are human carcinogens. Furthermore, women may experience higher bladder cancer risk than men from comparable arylamine exposure, possibly due in part to women's higher propensity for arylamine activation relative to men.

Abstract
The proliferation and migration of cells is a fundamental process for the metastasis of malignant tumour cells. In several in vitro studies, pertussis toxin (PTX) inhibited cell proliferation and cell motility in the human transitional cell carcinoma cell line J82. The present study investigated the effect of the intravesical application of PTX on the development of superficial bladder cancer in rats. We used the model of N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN, 0.05% via drinking water x10 weeks) to induce superficial bladder carcinomas in 40 female rats. After 16 weeks the rats were treated in two groups with 0.4 ml PTX (1 microg/ml) or 0.4 ml phosphate buffered saline (PBS) by intravesical application (once a week for 10 weeks). In the 25th week urine cytology was determined and all rats were killed at week 26 followed by histological evaluation. In the control group, the urine cytology was positive for G2/G3 cells in ten of 17 rats. In the PTX group G2/G3 cells were determined in five of 20 rats ( P two tailed <0.05). Histopathologically 12 rats (71%) of the control group and 11 rats (55%) of the PTX group developed T1-T2 transitional-cell carcinomas. No local or systemic side effects were disclosed. PTX treatment reduces the development of G3 transitional cell carcinomas in rats and may represent a new approach for local therapy in superficial bladder cancer.

Abstract
A 65-year-old female had been taking analgesics containing phenacetin, because of severe headaches since 1958. The total dose of phenacetin that she had taken was calculated to be 8.0 kg. She visited the department of urology in our hospital in August, 1999 complaining of gross hematuria. A solid mass was detected in her left renal pelvis on the abdominal computed tomographic (CT) scan. Under the diagnosis of a left renal pelvic tumor, nephrouretectomy was performed in September, 1999. Histopathological diagnosis was grade 2 transitional cell carcinoma. Interstitial nephritis was also observed. Our case is the twenty-second report of an urinary tract tumor associated with phenacetin abuse in Japan.

Abstract
Cyclophosphamide is considered to be a bladder carcinogen and there are many reports of secondary bladder cancer, while only a few cases of upper urothelial cancer have been described. A 59-year-old man, who had received cyclophosphamide therapy for malignant lymphoma, was suffering from gross hematuria and consulted our institute. Computerized tomography (CT), intravenous pyelography (IVP) and retrograde pyelography (RP) revealed a left renal pelvic tumor. Urinary cytology showed class V and radical left nephroureterectomy was performed. Histopathological diagnosis of the left renal pelvic tumor was transitional cell carcinoma, invading the renal parenchyma. He is free from recurrence eight months after surgery. To our knowledge, this is the third case of cyclophosphamide-induced upper urothelial carcinoma reported in Japan, and the twelfth reported in the English literature.
