Abstract
Aims and Background The main characteristic of urothelial bladder cancer is a clear predisposition to recurrence and disease progression. The aim of this study was to assess the possible relationship between cyclooxygenase-2 (COX-2) immunoreactivity in superficial urothelial bladder carcinoma and tumor grade, stage, number of recurrences and clinical disease progression. Methods In this prospective study 70 consecutive patients who underwent transurethral resection for superficial urothelial bladder cancer were included. Tumor slides were immuno-histochemically stained for COX-2, and COX-2 immunoreactivity in tumor and inflammatory stromal cells was categorized as negative or mildly, moderately or strongly positive. Patients were followed up for 2 years, and during this period the possible association of COX-2 immunoreactivity with tumor stage and grade, number of recurrences and progression of disease was evaluated. Results COX-2 immunoreactivity in tumor cells was found in 57 (81.4%) patients and did not correlate with tumor grade, stage of disease, number of recurrences, and progression of disease. COX-2 immunoreactivity in inflammatory cells was found in 16 of the 57 patients with COX-2 positive tumors, and was significantly related to the number of recurrences, time to appearance of the first recurrence, and disease progression. Conclusions COX-2 immunoreactivity in inflammatory stromal cells adjacent to the COX-2-positive tumor might be useful in clinical practice for selection of patients with a high risk of tumor recurrence and disease progression.

Abstract
Background: Response to neoadjuvant cisplatin treatment in bladder cancer has been linked to expression of Bcl-2 protein by cancer cells. The objective of this study was to test Bcl-2 as a predictive marker of neoadjuvant cisplatin chemotherapy response in a patient cohort from randomized cystectomy trials. Methods: Tumor samples were taken from 247 patients with T2-T4 bladder cancer enrolled in two randomized trials comparing cystectomy with or without neoadjuvant chemotherapy. Tissue microarrays from pre-intervention transurethral resection specimens were assessed for Bcl-2 protein status by immunohistochemistry. Extension of staining above 10% was regarded as positive. Downstaging and survival ratios in relation to Bcl-2 immunoreactivity and neoadjuvant chemotherapy utilization were calculated using the log rank test and multivariate Cox proportional hazards regression analyses. Results: Bcl-2 expression was positive in 38% and negative in 62% of the 236 evaluable patients. Bcl-2 negative patients receiving neoadjuvant chemotherapy had a significant increase in survival (p = 0.009), while Bcl-2 positive patients showed no difference (p = 0.4). However, the interaction variable between neoadjuvant chemotherapy and biomarker status was not significant (p = 0.38). When the prognostic value was assessed in the no-chemotherapy group, 5-year overall survival times were significantly better among Bcl-2 positive patients than among Bcl-2 negative patients (42 months vs 33 months, p = 0.04), but again Bcl-2 status did not remain independent when other factors were adjusted. Also, in a multivariate analysis with all patients, Bcl-2 was not significant. Conclusions: Bcl-2 status is not an independent predictor of neoadjuvant cisplatin chemotherapy response and is not prognostic in muscle-invasive bladder cancer.

Abstract
Objectives: To investigate the role of fluid intake from beverages before and after a diagnosis of bladder cancer in relation to the risk of developing bladder cancer recurrence. Study Design: Prospective cohort study. Methods: 716 patients with non-muscle invasive bladder cancer (NMIBC), who received transurethral resection of a primary bladder tumour (TURBT) and completed self-administrated questionnaires on usual fluid intake from beverages at time of diagnosis (over the year before diagnosis) and during follow-up (over the year after diagnosis), were included. Multivariable Cox regression was used to calculate hazard ratios and 95% confidence intervals of developing recurrent bladder cancer in relation to the intake of total fluid, total alcohol, and individual beverages. Results: During 2,025 person-years of follow-up, 238 (33%) of the included 716 NMIBC patients developed one or more recurrences of bladder cancer. Total fluid intake before diagnosis was not associated with a first recurrence of bladder cancer when comparing the highest and lowest intake group (HR = 0.98, 95% C.I. 0.70–1.38, p = 0.91). Comparable results were obtained for total fluid intake pre-diagnosis and the risk of developing multiple recurrences of bladder cancer (HR = 1.01, 95% C.I. 0.87–1.19, p = 0.85). A total of 379 of the 716 patients reported on usual fluid intake within 1 year of diagnosis. No significant associations between total fluid intake 1 year after diagnosis and a first recurrence of bladder cancer were found when comparing the highest and lowest intake group (HR = 0.91; 95% C.I. 0.60–1.37, p = 0.65) or with multiple recurrences of bladder cancer (HR = 1.06; 95% C.I. 0.89–1.26, p = 0.54). In addition, total alcohol intake and individual beverages were not associated with bladder cancer recurrence. Conclusions: The results indicate that an individual’s fluid intake from beverages is unlikely to have an important role in bladder cancer recurrence.

Proteomic Identification of the Galectin-1-Involved Molecular Pathways in Urinary Bladder Urothelial Carcinoma. Int J Mol Sci 2018; 19:ijms19041242. [PMID: 29671787 PMCID: PMC5979315 DOI: 10.3390/ijms19041242] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2018] [Revised: 04/10/2018] [Accepted: 04/16/2018] [Indexed: 01/04/2023] Open
Abstract
Among various heterogeneous types of bladder tumors, urothelial carcinoma is the most prevalent lesion. Some of the urinary bladder urothelial carcinomas (UBUCs) develop local recurrence and may cause distal invasion. Galectin-1 de-regulation significantly affects cell transformation, cell proliferation, angiogenesis, and cell invasiveness. In continuation of our previous investigation on the role of galectin-1 in UBUC tumorigenesis, in this study, proteomics strategies were implemented in order to find more galectin-1-associated signaling pathways. The results of this study showed that galectin-1 knockdown could induce 15 down-regulated proteins and two up-regulated proteins in T24 cells. These de-regulated proteins might participate in lipid/amino acid/energy metabolism, cytoskeleton, cell proliferation, cell-cell interaction, cell apoptosis, metastasis, and protein degradation. The aforementioned dys-regulated proteins were confirmed by western immunoblotting. Proteomics results were further translated to prognostic markers by analyses of biopsy samples. Results of cohort studies demonstrated that over-expressions of glutamine synthetase, alcohol dehydrogenase (NADP+), fatty acid binding protein 4, and toll interacting protein in clinical specimens were all significantly associated with galectin-1 up-regulation. Univariate analyses showed that de-regulations of glutamine synthetase and fatty acid binding protein 4 in clinical samples were respectively linked to disease-specific survival and metastasis-free survival.

Abstract
Human galectin-1 is a member of the galectin family, proteins with conserved carbohydrate-recognition domains that bind galactoside. Galectin-1 is highly expressed in various tumors and participates in various oncogenic processes. However, detailed descriptions of the function of galectin-1 in urinary bladder urothelial carcinoma have not been reported. Our previous cohort investigation showed that galectin-1 is associated with tumor invasiveness and is a possible independent prognostic marker of urinary bladder urothelial carcinoma. The present study aimed to clarify the relevance of galectin-1 expression level to tumor progression and invasion. In order to decipher a mechanism for the contribution of galectin-1 to the malignant behavior of urinary bladder urothelial carcinoma, two bladder cancer cell lines (T24 and J82) were established with knockdown of galectin-1 expression by shRNA. Bladder cancer cells with LGALS1 gene silencing showed reduced cell proliferation, lower invasive capability, and lower clonogenicity. Extensive signaling pathway studies indicated that galectin-1 participated in bladder cancer cell invasion by mediating the activity of MMP9 through the Ras-Rac1-MEKK4-JNK-AP1 signaling pathway. Our functional analyses of galectin-1 in urinary bladder urothelial carcinoma provided novel insights into the critical role of galectin-1 in tumor progression and invasion. These results revealed that silencing the galectin-1-mediated MAPK signaling pathway presented a novel strategy for bladder cancer therapy.

Abstract
Non-muscle-invasive bladder cancer (NMIBC) may progress to muscle-invasive disease, but no effective preventive treatments are available. In addition, no reliable prognostic biomarkers have been identified. We assessed the long-term effect of the oral retinoid fenretinide and the prognostic value of circulating VEGF levels. We updated through the Tumor Registry the vital status of 99 patients with resected Ta/T1 bladder tumors who were recruited in a randomized trial of 2 years of fenretinide or no treatment in 1993-1994. Serum VEGF levels measured at baseline and 12 months were available in a subgroup of 62 patients. After a median of 20.5 years, 54 subjects died, 35 of any cancer and 14 of bladder cancer. Neither overall survival (OS), nor cancer survival (CS) or bladder cancer survival (BCS) was affected by fenretinide (log-rank P ≥ 0.2). DNA aneuploidy in bladder washing was associated with shorter OS (P = 0.02), CS (P = 0.05), and BCS (P = 0.09). Subjects with baseline VEGF levels in the top quintile (≥350 pg/mL) had a significantly shorter OS (P = 0.01), CS (P = 0.02), and BCS (P = 0.008). The trend across quintiles of VEGF was significant for BCS (P = 0.007). Multivariate analyses showed that, in addition to smoking status, VEGF level in the top quintile was an independent prognostic factor for OS (HR = 2.7; 95% CI, 1.1-6.5), CS (HR = 3.3; 95% CI, 1.1-9.4) and BCS (HR = 8.9; 95% CI,1.3-61). Fenretinide did not affect the long-term outcome of patients with NMIBC. High serum VEGF level was a significant predictor of overall and cancer death and may help to identify high-risk subjects who may benefit from a preventive therapy.

Clarification of the molecular pathway of Taiwan local pomegranate fruit juice underlying the inhibition of urinary bladder urothelial carcinoma cell by proteomics strategy. Altern Ther Health Med 2016; 16:96. [PMID: 26955879 PMCID: PMC4784391 DOI: 10.1186/s12906-016-1071-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2015] [Accepted: 03/02/2016] [Indexed: 02/06/2023]
Abstract
Background Pomegranate fruit has been shown to exhibit the inhibitory activity against prostate cancer and lung cancer in vitro and in vivo, which might be a resource for chemoprevention and chemotherapy of cancer. Our previous documented findings indicated that treatment of urinary bladder urothelial carcinoma cell with the ethanol extract isolated from the juice of pomegranate fruit grown in Taiwan could inhibit tumor cell. In this study we intended to uncover the molecular pathway underlying anti-cancer efficacy of Taiwan pomegranate fruit juice against urinary bladder urothelial carcinoma. Methods We exploited two-dimensional gel electrophoresis coupled with tandem mass spectrometry to find the de-regulated proteins. Western immunoblotting was used to confirm the results collected from proteomics study. Results Comparative proteomics indicated that 20 proteins were differentially expressed in ethanol extract-treated T24 cells with 19 up-regulated and 1 down-regulated proteins. These de-regulated proteins were involved in apoptosis, cytoskeleton regulation, cell proliferation, proteasome activity and aerobic glycolysis. Further studies on signaling pathway demonstrated that ethanol extract treatment might inhibit urinary bladder urothelial carcinoma cell proliferation through restriction of PTEN/AKT/mTORC1 pathway via profilin 1 up-regulation. It also might evoke cell apoptosis through Diablo over-expression. Conclusions The results of this study provide a global picture to further investigate the anticancer molecular mechanism of pomegranate fruit.

Abstract
Bladder cancer occurs in the epithelial lining of the urinary bladder and is amongst the most common types of cancer in humans, killing thousands of people a year. This paper is based on the hypothesis that the use of clinical and histopathological data together with information about the concentration of various molecular markers in patients is useful for the prediction of outcomes and the design of treatments of nonmuscle invasive bladder carcinoma (NMIBC). A population of 45 patients with a new diagnosis of NMIBC was selected. Patients with benign prostatic hyperplasia (BPH), muscle invasive bladder carcinoma (MIBC), carcinoma in situ (CIS), and NMIBC recurrent tumors were not included due to their different clinical behavior. Clinical history was obtained by means of anamnesis and physical examination, and preoperative imaging and urine cytology were carried out for all patients. Then, patients underwent conventional transurethral resection (TURBT) and some proteomic analyses quantified the biomarkers (p53, neu, and EGFR). A postoperative follow-up was performed to detect relapse and progression. Clusterings were performed to find groups with clinical, molecular markers, histopathological prognostic factors, and statistics about recurrence, progression, and overall survival of patients with NMIBC. Four groups were found according to tumor sizes, risk of relapse or progression, and biological behavior. Outlier patients were also detected and categorized according to their clinical characters and biological behavior.

Abstract
The pathogenesis and transition of normal urothelium into bladder carcinoma are multifactorial processes. Chronic inflammation causes initiation and progression of the underlying pathophysiology of invasive and metastatic cancer. A dichotomy is observed in the role of immune cells in bladder cancer. While the immune response defends the host by suppressing neoplastic growth, several immune cells, including neutrophils, macrophages and T-lymphocytes, promote tumor development and progression. The levels of human neutrophil peptide-1, -2 and -3, produced by neutrophils, increase in bladder cancer and might promote tumor angiogenesis and growth. The effect of macrophages is primarily mediated by pro-inflammatory cytokines, IL-6 and TNF-α. In addition, the underlying immunological mechanisms of two treatments, BCG and cytokine gene-modified tumor vaccines, and future directions are critically discussed.

Abstract
Met is a tyrosine kinase receptor that is considered to be a proto-oncogene. The hepatocyte growth factor (HGF)-Met signaling system plays an important role in tumor growth, invasion, and metastasis in many types of malignancies. Furthermore, Met expression has been reported to be a useful predictive biomarker for disease progression and patient survival in these malignancies. Many studies have focused on the clinical significance and prognostic role of Met in urological cancers, including prostate cancer (PCa), renal cell carcinoma (RCC), and urothelial cancer. Several preclinical studies and clinical trials are in progress. In this review, the current understanding of the pathological role of Met in cancer cell lines, its clinical significance in cancer tissues, and its predictive value in patients with urological cancers are summarized. In particular, Met-related malignant behavior in castration-resistant PCa and the different pathological roles Met plays in papillary RCC and other histological types of RCC are the subjects of focus. In addition, the pathological significance of phosphorylated Met in these cancers is shown. In recent years, Met has been recognized as a potential therapeutic target in various types of cancer; therapeutic strategies used by Met-targeted agents in urological cancers are summarized in this review.

Abstract
PURPOSE Galectin-1 is highly expressed in various tumors and participates in various oncogenic processes. Our previous proteomics investigation demonstrated that galectin-1 is up-regulated in high compared to nonhigh grade lesions. Thus, in the current cohort study we clarified the correlation of galectin-1 over expression with various clinicopathological features and prognosis. MATERIALS AND METHODS We selected 185 cases of consecutively treated primary localized bladder urothelial carcinoma for study. Transurethral resection of bladder tumor was performed in all patients followed by radical cystectomy in those with T2 to T4 tumors. Pathological slides were examined to determine cytoplasmic galectin-1 immuno-expression and correlate galectin-1 dysregulation with various clinicopathological factors and disease specific survival. RESULTS Positive galectin-1 immuno-expression in tumors was significantly linked to pT status (p = 0.0295), histological grade (p = 0.037), vascular invasion (p = 0.0287) and nodal status (p = 0.0012). Galectin-1 over expression in tumors significantly predicted disease specific survival at the univariate (p = 0.0002) and multivariate levels (p = 0.03, HR 2.438, 95% CI 1.090-5.451). In situ hybridization indicated that the LGALS1 gene was amplified in 43 specimens in an independent cohort of 56 snap frozen tumor specimens. Association analysis showed that an increased LGALS1 mRNA level was linked to bladder urothelial carcinoma invasiveness (p = 0.016) and LGALS1 gene amplification was significantly associated the amount of GAL-1 protein in tumors (p <0.0001). On the univariate level gene amplification was also closely linked to disease specific survival (p = 0.0006). CONCLUSIONS These results reveal that galectin-1 over expression is a possible independent factor for bladder cancer prognosis.

Abstract
Background Pomegranate possesses many medicinal properties such as antioxidant, anti-inflammation and antitumor. It has been extensively used as a folk medicine by many cultures. Pomegranate fruit has been shown to have the inhibitory efficacy against prostate cancer and lung cancer in vitro and in vivo. It can be exploited in chemoprevention and chemotherapy of prostate cancer. In this study we examined the anti-cancer efficacy of pomegranate fruit grown in Taiwan against urinary bladder urothelial carcinoma (UBUC) and its mechanism of action. Methods Edible portion of Taiwanese pomegranate was extracted using ethanol and the anti-cancer effectiveness of ethanol extract was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Flow cytometry and western immunoblotting were exploited to uncover the molecular pathways underlying anti-UBUC activity of Taiwanese pomegranate ethanol extract. Results This study demonstrated that Taiwanese pomegranate fruit ethanol extract (PEE) could effectively restrict the proliferation of UBUC T24 and J82 cells. Cell cycle analyses indicated that the S phase arrest induced by PEE treatment might be caused by an increase in cyclin A protein level and a decrease in the expression of cyclin-dependent kinase 1. The results of western immunoblotting demonstrated that PEE treatment could not only evoke the activation of pro-caspase-3, -8,-9 but also increase Bax/Bcl-2 ratio in T24 cells. The above observations implicated that PEE administration might trigger the apoptosis in T24 cells through death receptor signaling and mitochondrial damage pathway. Besides we found that PEE exposure to T24 cells could provoke intensive activation of procaspase-12 and enhance the expressions of CHOP and Bip, endoplasmic reticulum (ER) stress marker, suggesting that ER stress might be the cardinal apoptotic mechanism of PEE-induced inhibition of bladder cancer cell. Conclusions The analytical results of this study help to provide insight into the molecular mechanism of induced bladder cancer cell apoptosis by pomegranate and to develop novel mechanism-based chemopreventive strategy for bladder cancer.

Abstract
The present studies determined whether clinically relevant phosphodiesterase 5 (PDE5) inhibitors interacted with clinically relevant chemotherapies to kill gastrointestinal/genitourinary cancer cells. In bladder cancer cells, regardless of H-RAS mutational status, at clinically achievable doses, PDE5 inhibitors interacted in a greater than additive fashion with doxorubicin/mitomycin C/gemcitabine/cisplatin/paclitaxel to cause cell death. In pancreatic tumor cells expressing mutant active K-RAS, PDE5 inhibitors interacted in a greater than additive fashion with doxorubicin/gemcitabine/paclitaxel to cause cell death. The most potent PDE5 inhibitor was sildenafil. Knock down of PDE5 expression recapitulated the combination effects of PDE5 inhibitor drugs with chemotherapy drugs. Expression of cellular FLICE-like inhibitory protein-short did not significantly inhibit chemotherapy lethality but did significantly reduce enhanced killing in combination with sildenafil. Overexpression of B-cell lymphoma-extra large suppressed individual and combination drug toxicities. Knock down of CD95 or Fas-associated death domain protein suppressed drug combination toxicity. Combination toxicity was also abolished by necrostatin or receptor interacting protein 1 knock down. Treatment with PDE5 inhibitors and chemotherapy drugs promoted autophagy, which was maximal at ∼24 hour posttreatment, and 3-methyl adenine or knock down of Beclin1 suppressed drug combination lethality by ∼50%. PDE5 inhibitors enhanced and prolonged the induction of DNA damage as judged by Comet assays and γhistone 2AX (γH2AX) and checkpoint kinase 2 (CHK2) phosphorylation. Knock down of ataxia telangiectasia mutated suppressed γH2AX and CHK2 phosphorylation and enhanced drug combination lethality. Collectively our data demonstrate that the combination of PDE5 inhibitors with standard of care chemotherapy agents for gastrointestinal/genitourinary cancers represents a novel modality.

Abstract
The purpose of this review is to demonstrate a successful use of preclinical models of bladder cancer to confirm the therapeutic potential of new promising drug candidates. The bladder has long been thought to be an ideal target for investigating therapies. When developing a new antineoplastic pharmaceutical agent, the bladder should be considered for use as an experimental model demonstrating initial proof of concept that if successful can be later assessed in further cancer indications. Non-muscle-invasive bladder carcinoma can be removed by transurethral resection but these cancers tend to recur in most patients. Conventional treatments decrease the recurrence rate but are associated with side effects and frequent failures. Thus, there is an obvious need for the development of highly effective targeted therapies with limited side effects. Accordingly, a double-promoter vector was developed, expressing diphtheria toxin A (DTA) under control of two different regulatory promoter sequences, H19 and IGF2. This vector was then used to transfect and to eradicate tumor cells in bladder cancer models, effectively destroying tumor cells without affecting normal cells. Our studies demonstrate the potential efficacy of the therapeutic vector and should be a solid base for future clinical studies. These models illuminate the path for future investigations of new drug candidates for bladder cancer.

Abstract
AIMS To detect human papilloma virus (HPV) infection, p21 oncogene, DNA content of urothelial cells in different bladder lesions with and without schistosomiasis and to correlate them with histopathological grade and stage. METHODS Eighty-five patients were enrolled: 25 chronic cystitis and 60 malignant bladder lesions; 15 schistosomal squamous cell carcinoma (SQCC), 45 urothelial carcinoma (transitional cell carcinoma TCC) schistosomal and non-scistosomal. Ten healthy individuals served as controls. Genotyping of HPV 6/11 and 16/18 were done using in situ hybridization and p21 protein expression by Immunohistochemical technique in formalin-fixed, paraffin-embedded tissues. DNA content of urothelial cells were stained with felugen stains and measured using Automated Image analysis System. RESULTS HPV DNA 6/11 and 16/18 expression was increased from cases of schistosomal cystitis with dysplasia to TCC with schistosomiasis compared to TCC and SQCC. The expression increased with statistical significance in invasive TCC and high-grade compared with superficial and low grade. Over-expression of p21 in invasive TCC group was compared with superficial TCC, high-grade TCC was compared low grade and TCC was compared with SQCC. Almost all cases of TCC associated with schistosomiasis exhibit aneuploid histogram compared to SQCC and all invasive TCC exhibited aneuploid histograms. CONCLUSIONS Both HPV infection and p21 gene abnormalities may contribute to bilharzial bladder carcinogenesis. DNA image cytometric features may predict stage progression in TCC. Expression of p21, DNA HPV 6/11 and 16/18 may be used as biological markers of bladder carcinoma.

Abstract
Interleukin (IL)-28A, also called IFN-λ2, is a member of the classIIcytokine family and has demonstrated anti-proliferative and anti-viral signals. The present study demonstrated migration inducement of IL-28A-treated bladder cancer cells - a novel function. RNA microarray analysis showed an enhanced expression of IL-28A and its receptor IL-28AR1 in muscle invasive urothelial carcinoma in a human bladder. Strong expression of IL-28A and IL-28AR1 was detected in bladder cancer tissues and cell lines (5637, T-24, and HT1376 cells), as determined by real-time PCR and immunoblot analysis. IL-28A treatment induced migration of bladder cancer cells, independent of the cell growth. IL-28AR1-specific small interfering RNA (si-IL-28AR1) inhibited the induction of migration in IL-28A-treated cells. IL-28A treatment stimulated the expression of matrix metalloproteinases-9 (MMP-9) via activation of transcription factor NF-κB. Gene knockdown for MMP-9 and the p65 subunit of NF-κB, using siRNA transfection, suppressed wound healing migration in IL-28A-treated bladder cancer cells. Also, treatment with IL-28A induced activation of mitogen-activated protein kinase (MAPK) in bladder cancer cells. MAPK function blockage by a MAPK-specific inhibitor showed that MAPK phosphorylation is required for IL-28A-induced MMP-9 expression through activation of NF-κB. The transient transfection of bladder cancer cells with ERK1/2 knock down (si-ERK1/2) and dominant negative p38 (DNp38) suppressed IL-28A-induced migration. IL-28A-induced induction of MMP-9 expression, MAPK activation, and DNA binding activity of NF-κB was abolished in the presence of IL-28A neutralizing antibody or by transfection of si-IL-28AR1. These results show that IL-28A/IL-28AR1 dyad-induced wound healing migration requires NF-κB-mediated MMP-9 expression by MAPK activation.

Abstract
Background Photodynamic therapy (PDT) is an attractive, emerging therapeutic procedure suitable for the treatment of non-muscle-invasive bladder cancer. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a death ligand that belongs to the TNF superfamily of cytokines. The ability of TRAIL to selectively induce apoptosis in cancer cells but not in normal cells promotes the development of TRAIL-based cancer therapy. However, many tumor cells are resistant to TRAIL-induced apoptosis. The purpose of the study was to overcome TRAIL-resistance in bladder cancer cells by photodynamic therapy (PDT). Material/Methods Three human bladder transitional cancer cell lines – T24, 647V and SW780 – were treated with TRAIL and/or chlorin-based PDT. The cytotoxicity was measured by MTT and LDH assays and apoptosis was detected using annexin V by flow cytometry. Results Our test confirmed that T24 and 647V bladder cancer cells are resistant to TRAIL, whereas SW780 cells are sensitive to TRAIL. Then we examined the cytotoxic and apoptotic effects of TRAIL in combination with chlorin e6-polyvinylpyrrolidone (Ce6-PVP)-mediated PDT on bladder cancer cells. We showed for the first time that pretreatment with a low dose of PDT significantly sensitizes bladder cancer cells to TRAIL-induced apoptosis. Chlorin-based PDT augments the effect of TRAIL on bladder cancer cells. Conclusions PDT with Ce6-PVP photosensitizer enhances the cytotoxic and apoptotic effects of TRAIL on bladder cancer cells. The obtained results suggest that combined treatment by TRAIL and PDT may provide the basis for a new therapeutic approach to induce cell death in bladder cancer.

Abstract
AIMS In our previous studies, comparative proteomics demonstrated that lactate dehydrogenase B subunit (LDH-B) is down-regulated in high grade compared to non-high grade urinary bladder urothelial carcinoma (UBUC). However, this finding has not been validated by clinical cohort investigation. Therefore, in the present study, 269 primary localised UBUC specimens were examined for LDH-B expression to clarify the relevance of LDH-B expression level to UBUC progression. METHODS Immunohistochemistry (IHC) was implemented to investigate LDH-B protein expression in 269 primary localised UBUC specimens and to evaluate the association with tumour progression and prognosis. RESULTS Our data demonstrated that dwindled LDH-B expression level was strongly associated with increment of primary tumour status (p < 0.0001), higher histological grade (p = 0.0024), and the presence of vascular (p = 0.0118) as well as perineurial (p = 0.0094) invasion, suggesting that LDH-B might be related to tumour progression. At the univariate level, low LDH-B expression is one of many parameters which significantly predicted both disease-specific survival (DSS) (p = 0.0001) and metastasis-free survival (MeFS) (p = 0.0024). In Cox multivariate regression model, higher pT status was the strongest independent prognosticator for both DSS (p = 0.0006) and MeFS (p = 0.0067) while low LDH-B expression remained prognostically significant for DSS (p = 0.0401). CONCLUSION The above results confirmed the prognostic roles of LDH-B in UBUC.

Abstract
Aurora-A is an oncogenic serine/threonine kinase, which plays important roles in tumorigenesis, development and chemoresistance of human cancers. The aim of the study was to detect the expression of Aurora-A gene in bladder cancer tissues and analyze its association with prognosis of bladder cancer patients. RT-PCR was performed to detect the expression of Aurora-A mRNA in 20 cases of bladder cancer and corresponding non-tumor tissue samples. Immunohistochemistry was performed to detect the localization of Aurora-A protein in 96 cases of bladder cancer tissue samples. Associations between Aurora-A protein expression and clinico-pathological factors or survival of bladder cancer patients were statistically analyzed. It was found that the expression levels of Aurora-A mRNA in bladder cancer tissues (1.08±0.24) were significantly higher than those in corresponding non-tumor tissues (0.22±0.07; P<0.01). Moreover, immunohistochemical staining results showed the localization of Aurora-A protein to be mainly located in the cytoplasm of bladder cancer cells. High levels of Aurora-A protein expression were correlated with pathological stage (P=0.007), lymph node metastasis (P=0.014) and venous invasion (P=0.008), but not with other factors including age, gender, tumor grade and recurrence of superficial cancer. Patients with high expression levels of Aurora-A protein showed lower disease-free and overall survival rates than those with low expression levels (P=0.0072 and 0.0009, respectively). Univariate and multivariate analysis of prognostic factors in bladder cancer patients indicated that Aurora-A expression was an independent unfavorable prognostic factor (hazard ratio: 0.673; 95% confidence interval: 0.388-0.912; P<0.001). Our study suggests that overexpression of Aurora-A gene may play an important role in the progression of bladder cancer and that Aurora-A expression is an independent factor for predicting the prognosis of bladder cancer in patients.

Abstract
Significant morbidity and expense result from frequent recurrences of nonmuscle-invasive bladder cancer (NMIBC) after standard treatment, and carcinoma in situ (Tis) is a poor prognostic factor. Predicated on observational and preclinical data strongly supporting cyclooxygenase-2 (COX-2) in the pathogenesis, and the activity of COX-2 inhibitors, in bladder cancer, we conducted a randomized, double-blind, placebo-controlled trial to determine whether celecoxib could reduce the time-to-recurrence (TTR) in NMIBC patients at high risk for recurrence. A total of 146 patients were randomized to celecoxib (200 mg) or placebo orally twice daily for at least 12 months. The average treatment duration was 1.25 years. Primary intent-to-treat analysis revealed celecoxib did not statistically significantly prolong TTR compared with placebo (P = 0.17, log rank) with a median follow-up of 2.49 years. The recurrence-free rate at 12 months with celecoxib was 88% (95% CI: 0.81-0.96) versus 78% (95% CI: 0.69-0.89) with placebo. After controlling for covariates with Cox regression analysis, recurrence rates did not differ between the two study arms (HR = 0.69; 95% CI: 0.37-1.29). However, celecoxib had a marginally significant effect on reducing metachronous recurrences (vs. placebo) with HR of 0.56 (95% CI: 0.3-1.06; P = 0.075). Celecoxib was well tolerated, with similar adverse events and quality-of-life in both arms. Our clinical trial results do not show a clinical benefit for celecoxib in preventing NMIBC recurrence but further investigation of COX-2 inhibitors in this setting is warranted.

Abstract
Aggressive bladder cancer is a major cause of morbidity and mortality. Despite the fact that metastatic disease results in death in the majority of bladder cancer cases, the molecular events regulating the invasive phenotype of aggressive bladder cancer are not well understood. In this study, immunohistochemical examination showed that the leukotriene B(4) receptor BLT2 is overexpressed in advanced malignant bladder cancers (human transitional cell carcinomas) in proportion to advancing stages, with high prognostic significance (p<0.001). Blockade of BLT2 with the specific antagonist LY255283 or siRNA knockdown significantly suppressed the invasiveness of highly aggressive 253J-BV bladder cancer cells. Moreover, our results demonstrated that BLT2 mediates invasiveness through a signaling pathway dependent on NAD(P)H oxidase (Nox) 1- and Nox4-induced generation of reactive oxygen species (ROS) and subsequent NF-kappaB stimulation. Metastasis of 253J-BV cells in mice was also dramatically suppressed by inhibition of BLT2 or its signaling. These findings suggest that a BLT2-Nox-ROS-NF-kappaB cascade plays a critical role in bladder cancer invasion and metastasis.

Abstract
IMPORTANCE OF THE FIELD Platinum-based chemotherapy is considered the standard-of-care first-line therapy for metastatic bladder cancer. Despite the initial high response rate, the vast majority of patients eventually progress and succumb to their disease, urging the need for development of novel therapies. AREAS COVERED IN THIS REVIEW This article discusses the main signaling pathways implicated in the pathogenesis of bladder carcinomas, reviews recently completed and ongoing clinical trials, and anticipates the future direction of molecularly targeted agents. WHAT THE READER WILL GAIN This manuscript presents the current status of conventional chemotherapy in advanced bladder cancer, and provides a comprehensive review of molecular targeted agents currently in clinical development for this disease. TAKE HOME MESSAGE Improved understanding of the biology of urothelial carcinogenesis has paved the way for the development of novel molecularly targeted therapies, several of which are currently tested in clinical trials. In this regard, VEGF and EGFR pathways are emerging as important therapeutic targets for metastatic bladder cancer, either alone or in combination with conventional chemotherapeutics. Other therapies, including aurora kinase inhibitors, endothelin receptor antagonists, RAS/MAPK pathway inhibitors and novel immunologic strategies, may also prove helpful in the treatment of this disease.

Abstract
BACKGROUND Updated National Academy of Clinical Biochemistry Laboratory Medicine Practice Guidelines for the use of tumor markers in the clinic have been developed. METHODS Published reports relevant to use of tumor markers for 4 cancer sites--liver, bladder, cervical, and gastric--were critically reviewed. RESULTS Alpha-fetoprotein (AFP) may be used in conjunction with abdominal ultrasound for early detection of hepatocellular carcinoma (HCC) in patients with chronic hepatitis or cirrhosis associated with hepatitis B or C virus infection. AFP concentrations >200 microg/L in cirrhotic patients with typical hypervascular lesions >2 cm in size are consistent with HCC. After a diagnosis of HCC, posttreatment monitoring with AFP is recommended as an adjunct to imaging, especially in the absence of measurable disease. Although several urine markers have been proposed for bladder cancer, none at present can replace routine cystoscopy and cytology in the management of patients with this malignancy. Some may, however, be used as complementary adjuncts to direct more effective use of clinical procedures. Although carcinoembryonic antigen and CA 19-9 have been proposed for use gastric cancer and squamous cell carcinoma antigen for use in cervical cancer, none of these markers can currently be recommended for routine clinical use. CONCLUSIONS Implementation of these recommendations should encourage optimal use of tumor markers for patients with liver, bladder, cervical, or gastric cancers.

Abstract
AIMS In our previous studies, comparative proteomics and immunohistochemistry (IHC) demonstrated that annexin-I (ANXA1) is up-regulated in high grade urinary bladder urothelial carcinoma (UBUC) as compared to non-high grade carcinomas. However, the small sample size prohibited further correlation of ANXA1 expression to tumour progression. Therefore, in the present study, 81 primary localised UBUC specimens of various grades and primary tumour (pT) status were examined for ANXA1 expression to further confirm the proteomics data and to clarify the relevance of ANXA1 expression level to the prognosis of UBUC. METHODS IHC was implemented to investigate ANXA1 protein expression in 81 primary localised UBUC specimens. The association of ANXA1 expression with tumour progression and prognosis was analysed. RESULTS Our data demonstrated that the ANXA1 expression level was strongly associated with an escalated pT status (p < 0.001) and a higher histological grade (p < 0.001), suggesting that ANXA1 might be related to tumour progression. Moreover, at the univariate level, ANXA1 overexpression, along with higher pT status and histological grade, significantly predicted disease-specific survival (DSS) and metastasis-free survival (MFS). More importantly, multivariate analyses revealed that the association of ANXA1 overexpression and prognosis remained significant for both DSS and MFS. CONCLUSION The above results reinforced the comparative proteomics results and confirmed the prognostic role of ANXA1 in UBUC.

Abstract
Protein-protein interactions (PPIs) have been widely studied to understand the biological processes or molecular functions associated with different disease systems like cancer. While focused studies on individual cancers have generated valuable information, global and comparative analysis of datasets from different cancer types has not been done. In this work, we carried out bioinformatic analysis of PPIs corresponding to differentially expressed genes from microarrays of various tumor tissues (belonging to bladder, colon, kidney and thyroid cancers) and compared their associated biological processes and molecular functions (based on Gene Ontology terms). We identified a set of processes or functions that are common to all these cancers, as well as those that are specific to only one or partial cancer types. Similarly, protein interaction networks in nucleic acid metabolism were compared to identify the common/specific clusters of proteins across different cancer types. Our results provide a basis for further experimental investigations to study protein interaction networks associated with cancer. The methodology developed in this work can also be applied to study similar disease systems.

Abstract
The optimal treatment of lamina propria invasive bladder cancers remains controversial. Assigning strict treatment guidelines is hampered by the heterogeneous clinical behavior of lamina propria invasive bladder cancers. Although many T1 lesions respond very well to transurethral resection and adjuvant intravesical therapy, others demonstrate a high rate of recurrence and progression. While bladder preservation is desired by most patients, experience has documented that survival is compromised in a substantial percentage of patients if T1 disease is allowed to progress. Radical cystectomy for T1 disease is associated with an excellent survival; however, the optimal timing of radical cystectomy remains one of the more difficult clinical dilemmas in the management of patients with bladder cancer. This article reviews the various features associated with an increased risk of disease progression to provide a framework for optimizing the timing of radical cystectomy.

Abstract
CONTEXT This review focuses on the prediction of recurrence and progression in non-muscle invasive bladder cancer (NMIBC) and the treatments advocated for this disease. OBJECTIVE To review the current status of epidemiology, recurrence, and progression of NMIBC and the state-of-the art treatment for this disease. EVIDENCE ACQUISITION A literature search in English was performed using PubMed and the guidelines of the European Association of Urology and the American Urological Association. Relevant papers on epidemiology, recurrence, progression, and management of NMIBC were selected. Special attention was given to fluorescent cystoscopy, the new World Health Organisation 2004 classification system for grade, and the role of substaging of T1 NMIBC. EVIDENCE SYNTHESIS In NMIBC, approximately 70% of patients present as pTa, 20% as pT1, and 10% with carcinoma in situ (CIS) lesions. Bladder cancer (BCa) is the fifth most frequent type of cancer in western society and the most expensive cancer per patient. Recurrence (in < or = 80% of patients) is the main problem for pTa NMIBC patients, whereas progression (in < or = 45% of patients) is the main threat in pT1 and CIS NMIBC. In a recent European Organisation for Research and Treatment of Cancer analysis, multiplicity, tumour size, and prior recurrence rate are the most important variables for recurrence. Tumour grade, stage, and CIS are the most important variables for progression. Treatment ranges from transurethral resection (TUR) followed by a single chemotherapy instillation in low-risk NMIBC to, sometimes, re-TUR and adjuvant intravesical therapy in intermediate- and high-risk patients to early cystectomy for treatment-refractory high-risk NMIBC. CONCLUSIONS NMIBC is a heterogeneous disease with varying therapies, follow-up strategies, and oncologic outcomes for an individual patient.

Abstract
Non-muscle invasive bladder cancers (NMI-BCs) represent 75% of bladder cancers upon presentation. After removal of the primary tumour by transurethral resection, multiple recurrences continue to develop in 70% of patients. Consequently, prolonged and costly surveillance by cystoscopy is required. Mutations in the FGFR3 oncogene are common in NMI-BCs and are associated with a lower chance of progression to muscle-invasive disease. Here we analysed the consistency of FGFR3 mutations in primary and recurrent tumours. This knowledge is of crucial importance if FGFR3 mutation analysis on urinary cells is to be used as an alternative for cystoscopical surveillance. To this end, we monitored the disease process and FGFR3 mutation status of primary and recurrent tumours in 118 patients with NMI-BC. During median follow-up of 8.8 years, these patients underwent 2133 cystoscopies and 80 patients developed 414 recurrences. FGFR3 mutations were equally prevalent in primary and recurrent tumours (63%). Patients can have different types of FGFR3 mutations in different tumours. Recurrence risk was not significantly different for patients with a mutant or wild-type primary tumour. Recurrence rates varied widely between patients but were constant for a patient and were unrelated to FGFR3 status. In the mutant patient group, in contrast to the wild-type group, recurrences continued to develop after 10 years. In 81% of the recurrences of patients with a mutant primary tumour, a mutation was found. Moreover, recurrences in this patient group were of lower stage and grade than those of patients with a wild-type primary tumour (p < 0.001). These results suggest that surveillance by FGFR3 mutation analysis on voided urine in combination with a reduced cystoscopy frequency of patients presenting with an FGFR3 mutant tumour is worth investigating.

Abstract
Urine cytology is the most widely used noninvasive test to detect urothelial tumors. However, it is limited by its low sensitivity. On the other hand, cystoscopy is the gold standard procedure to follow patients with a history of bladder cancer but this test is invasive and costly. Therefore, there is a real need to develop new tests that can be used in bladder cancer surveillance. Several soluble and cell-based markers have been developed and most of them improve the sensitivity of cytology but the specificity is invariably decreased. Of the cell-based tests, two obtained Food and Drug Administration approval. ImmunoCyt/uCyt is a fluorescent test that uses three monoclonal antibodies and UroVysion is an in situ hybridization test, which uses four different probes to different chromosomes. Both tests have a high sensitivity to detect cancer cells and can help to predict urothelial cancer recurrence. ImmunoCyt/uCyt is somewhat better at detecting low-grade tumors but UroVysion is not affected by prior BCG treatment. However, both tests use fluorescent dyes, are time-consuming and require trained personnel. Because of their high negative predictive value, both tests may help the urologist to postpone a number of cystoscopies, especially in patients with low-risk urothelial cancer.

Abstract
Background The molecular mechanisms of the development and progression of bladder cancer are poorly understood. The objective of this study was to analyze the expression of Bmi-1 protein and its clinical significance in human bladder cancer. Methods We examined the expression of Bmi-1 mRNA and Bmi-1 protein by RT-PCR and Western blot, respectively in 14 paired bladder cancers and the adjacent normal tissues. The expression of Bmi-1 protein in 137 specimens of bladder cancer and 30 specimens of adjacent normal bladder tissue was determined by immunohistochemistry. Statistical analyses were applied to test the relationship between expression of Bmi-1, and clinicopathologic features and prognosis. Results Expression of Bmi-1 mRNA and protein was higher in bladder cancers than in the adjacent normal tissues in 14 paired samples (P < 0.01). By immunohistochemical examination, five of 30 adjacent normal bladder specimens (16.7%) versus 75 of 137 bladder cancers (54.3%) showed Bmi-1 protein expression (P < 0.05). Bmi-1 protein expression was intense in 20.6%, 54.3%, and 78.8% of tumors of histopathological stages G1, G2, and G3, respectively (P < 0.05). Expression of Bmi-1 protein was greater in invasive bladder cancers than in superficial bladder cancers (81.5% versus 32.5%, P < 0.05). In invasive bladder cancers, the expression of Bmi-1 protein in progression-free cancers was similar to that of cancers that have progressed (80.0% versus 82.4%, P > 0.5). In superficial bladder cancers, the expression of Bmi-1 protein in recurrent cases was higher than in recurrence-free cases (62.5% versus 13.7%, P < 0.05). Bmi-1 expression was positively correlated with tumor classification and TNM stage (P < 0.05), but not with tumor number (P > 0.05). Five-year survival in the group with higher Bmi-1 expression was 50.8%, while it was 78.5% in the group with lower Bmi-1 expression (P < 0.05). Patients with higher Bmi-1 expression had shorter survival time, whereas patients with lower Bmi-1 expression had longer survival time (P < 0.05). Conclusion Expression of Bmi-1 was greater in bladder cancers than in the adjacent normal tissues. The examination of Bmi-1 protein expression is potentially valuable in prognostic evaluation of bladder cancer.

Abstract
It has been suggested that progression of bladder transitional cell cancer (BTCC) may be regulated at the molecular level by a typical pattern of expression of genes involved in apoptosis. Recently Livin, belonging to the inhibitors of apoptosis (IAP) family, has been found to be expressed in most solid tumors, where its expression is suggested to have clinical significance. In order to explore the significance of Livin expression in the development of BTCC, immunohistochemistry and RT-QPCR were used to detect the expression of Livin mRNA in tumor tissues and adjacent normal tissues of 30 cases of BTCC. The results showed that the positive rate of Livin expression in adjacent normal tissues and tumor tissues was 0 and 60% (18/30) respectively. The-Delta Delta CT value of Livin in BTCC tissues was 8.0454 (7.4264-8.6644) times of that in adjacent normal tissues. The expression of Livin mRNA had no correlation with tumor pathological grades and clinical stages. It was suggested that there was weak expression of Livin mRNA in adjacent normal tissues, but strong in tumor tissues.

Abstract
Urothelial carcinoma is the second most common genitourinary malignancy. Although the majority of patients present with superficial bladder tumors, there are several clinical problems, such as progression to invasive tumors, poor prognosis of invasive tumors, and chemosensitivity. Alterations in p53 represent one of the most common genetic events in patients with invasive urothelial carcinoma and are suggested to be linked to tumor progression, prognosis, and chemosensitivity. p53 possesses various functions, including induction of cell-cycle arrest, apoptosis, DNA repair, and antioxidants; it acts as a killer and a healer. In this article, we review the roles of p53 pathways in bladder carcinogenesis and findings from recent studies of ours and other groups, and we discuss the clinical significance of the abrogation of p53 pathways in the treatment of urothelial carcinoma.

Abstract
We have applied protein expression profiling technologies in combination with immunohistochemistry, using fresh tissue and urine samples, to assess bladder cancer heterogeneity and prognosis as well as to generate protein markers for tumor progression and early diagnosis of the disease. Here, we review some selected lines of investigation and approaches undertaken by our laboratory, drawing on more than 15 years of experience in bladder cancer proteomics, to highlight a number of issues that may be useful for researchers entering the field. In particular, we address the identification of markers for bladder cancer progression and exemplify the potential of gel-based proteomic profiling of urine samples for the early detection of urothelial carcinomas. In addition, we provide a brief description of a novel and highly promising source of biomarkers, the tumor interstitial fluid (TIF) that perfuses the tumor microenvironment.

Abstract
BACKGROUND N1,N12-diacetylspermine, a diacetylpolyamine which was recently identified in urine, appeared to be a useful tumor marker for a number of cancers. No valid data on urine diacetylspermine concentration in patients with urinary bladder cancer exist. AIM Evaluation of urine N1,N12-diacetylspermine concentrations in individuals with urinary bladder cancer. METHODS Urine samples were used from 36 patients with urothelial tumors of the urinary bladder and from 30 patients with benign urological diseases. Urine was collected before cystoscopy. Enzyme-linked immunoabsorbent assays (ELISA) were performed for diacetylspermine from urine. RESULTS Urine diacetylspermine did not differentiate in individuals with urinary bladder cancer from controls (medians 171.5 vs 143.8, p = 0.64). Its efficacy for urinary bladder cancer detection was not shown. CONCLUSIONS Urine N1,N12-diacetylspermine is probably not a useful marker for urinary bladder cancer.

Abstract
PURPOSE TIMP-3 (tissue inhibitor of metalloproteinases-3) is 1 of 4 members of a family of proteins that were originally classified according to their ability to inhibit matrix metalloproteinases. We analyzed TIMP-3 methylation in 175 urine sediment DNA samples from patients with bladder cancer with well characterized clinicopathological parameters, including patient outcome. MATERIALS AND METHODS We examined urine sediment DNA for aberrant methylation of 9 genes, including TIMP-3, by quantitative fluorogenic real-time polymerase chain reaction. RESULTS Using an optimal cutoff value by TaqMan(R) quantitation we found that the risk of death was statistically significantly higher in patients with higher TIMP-3 and ARF methylation (HR 1.99, 95% CI 1.12 to 3.27, p = 0.01 and HR 1.66, 95% CI 1.00 to 2.76, p = 0.05, respectively) than in patients without/lower TIMP3 and ARF methylation in urine. A significant correlation was also seen between the risk of death and stage 3 tumor (HR 2.73, 95% CI 1.58 to 4.72, p = 0.003) and metastasis (HR 3.32, 95% CI 1.98 to 5.57, p = 0.0001). Multivariate analysis subsequently revealed that TIMP-3 methylation was an independent prognostic factor for bladder cancer survival with stage and metastasis (p = 0.001 and 0.02, respectively). CONCLUSIONS These results suggest that TIMP-3 promoter methylation could be a clinically applicable marker for bladder cancer progression.

Abstract
More than 90% of bladder tumors are diagnosed as bladder transitional cell carcinoma and the majority of these lesions (70%) are diagnosed as superficial papillary lesions (stage pTa, T1). Recurrences are common to superficial tumors and few lesions will progress to a higher grade and/or stage and muscle invasion. Thus, diagnosing cancer at an early stage, predicting whether a tumor will recur and/or progress and identification of novel targets for cancer intervention, become the main focus of bladder cancer research. The purpose of this article is to briefly review what has been accomplished to date by using proteomic technology in order to develop a new strategy to resolve the problems of early detection, recurrence or therapeutic intervention.

Abstract
PURPOSE OF REVIEW Patients with muscle-invasive bladder cancer will practically all develop progression, often associated with severe side effects including pain, dysuria or macrohematuria. Recent reports demonstrate multimodality bladder-sparing approaches as primary treatment for muscle-invasive bladder cancer. RECENT FINDINGS Bladder-conserving strategies include thorough transurethral resection of the bladder tumor, external beam radiation therapy and chemotherapy. It has been shown that survival rates are similar to those of radical cystectomy series; additionally, a substantial number of patients survive with an intact bladder. The high costs, close cooperation between clinical specialists and a highly compliant patient need to be taken into consideration, however. SUMMARY Nowadays, the good long-term results after radical cystectomy with the creation of an orthotopic neobladder make the substantial advantage of a bladder-preserving strategy questionable when the patient's quality of life is addressed. Multimodality bladder-conserving strategies are a therapeutic option for selected patients; however, radical cystectomy remains the gold standard of treatment.

Abstract
Traditional criterions are not sufficient to predict accurately the recurrence of transitional cell carcinoma of the urinary bladder. Therefore, we aimed to evaluate the AgNORs via total AgNOR area/nucleus area (TAA/NA) for each cell as a prognostic parameter, in TCC of urinary bladder. Tumor tissues of 20 consecutive cases of male bladder cancer patients were divided into two groups as middle differentiated (LG) and high grade (HG). The extra-tumoral tissue (ETT) samples of 10 males served as control group. A second control group (HC) consisted of five healthy and normal bladder tissue samples. The 3 microm of sections from each paraffin embedded tumoral, extra-tumoral and normal tissue samples served as patient and control groups. After deparaffinization and rehydratation steps, silver (AgNO(3)) staining of nucleolar organizer regions-associated proteins (AgNORs) was performed. Instead of Giemsa stain, we used Hematoxylin for contra staining. The images of the 100 analyzable nuclei from each tissue sample, transferred by means of a video camera and video capture card from microscope and recorded onto a computer. Software was prepared in Delphi language for analysis. Mean (E+02) TAA/NA values of HC, ETT, LG and HG groups were 6.97+2.80, 5.70+1.82, 7.80+3.22 and 9.24+3.88, respectively. Statistical comparisons have shown significant differences between all groups. In conclusion, mean TAA/NA per cell has a potential to be a prognostic parameter. Therefore, further evaluation of big patient series will be useful.
