Abstract
BACKGROUND Bladder cancer is one of the most common malignant tumors of the urinary system, and its incidence is increasing worldwide. However, the underlying mechanisms that trigger migration, invasion and chemotherapy resistance are unclear. RESULTS Bioinformatics analysis of bladder cancer cohort indicated that LINC00839 is deregulated in bladder cancer. LINC00839 was validated and highly expressed in bladder cancer patients and cell lines. In addition, LINC00839 induced the migration, invasion and Gemcitabine resistance of bladder cancer cells. We identified that the transcription factor EGR1 directly repressed LINC00839 and thereby suppressed the migration and invasion of bladder cancer cells. Furthermore, LINC00839 interacted with miR-142, which subsequently regulated the expression of SOX5, a well-studied oncogene and targeted by miR-142. In addition, EGR1 served as a suppressive transcription factor of SOX5. Therefore, EGR1 directly or indirectly regulates SOX5 via LINC00839/miR-142 axis. LINC00839 induced Gemcitabine resistance by promoting autophagy. CONCLUSIONS EGR1, LINC00839/miR-142 and SOX5 form a coherent feed-forward loop that modulates the migration, invasion and Gemcitabine resistance of bladder cancer.

Abstract
Cisplatin-based chemotherapy is the standard treatment for bladder urothelial carcinoma (UC). Most patients experience chemoresistance, the primary cause of treatment failure, which leads to disease relapse. The underlying mechanism of chemoresistance involves reduced apoptosis. In this study, we investigated the antitumor effect of the deubiquitylating enzyme inhibitor PR-619 in cisplatin-resistant bladder UC. Deubiquitinase (ubiquitin-specific protease 14 (USP14) and USP21) immunohistochemical staining demonstrated that deubiquitination is related to chemoresistance in patients with metastatic UC and may be a target for overcoming chemoresistance. Cytotoxicity and apoptosis were assessed using fluorescence-activated flow cytometry and a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium assay, and PR-619 was found to enhance the cytotoxic and apoptotic effects of cisplatin in cisplatin-resistant T24/R cells. Mitigated cisplatin chemoresistance was associated with the concurrent suppression of c-Myc expression in T24/R cells. Moreover, the expression of c-Myc was upregulated in human bladder UC specimens from patients with chemoresistance. Experiments in a xenograft nude mouse model confirmed that PR-619 enhanced the antitumor effects of cisplatin. These results are promising for the development of therapeutic strategies to prevent UC chemoresistance through the combined use of chemotherapeutic agents/deubiquitination inhibitors (PR-619) by targeting the c-Myc pathway.

Abstract
Aim: To compare the overall survival of patients with metastatic urothelial carcinoma (mUC) who failed platinum-based chemotherapy and received durvalumab or chemotherapy. Patients & methods: In an indirect comparison of patients with mUC who failed platinum-based chemotherapy, those who received durvalumab in a single-arm study were matched to patients from the Flatiron oncology electronic medical record database who received chemotherapy (n = 158 for each cohort). Matching was based on propensity scores. Kaplan-Meier methods and Cox regression models were utilized. Results: Median overall survival was 11.2 months (95% CI: 7.2-16.9) for durvalumab versus 8.2 months (95% CI: 6.7-9.8) for chemotherapy (hazard ratio: 0.63; 95% CI: 0.48-0.84). Conclusion: As a second-line therapy for mUC, durvalumab was associated with longer overall survival than chemotherapy.

Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) are approved for first-line (cisplatin unfit, PD-L1+) and platinum-refractory urothelial carcinoma (UC). Still, most patients experience progressive disease (PD) as the best response. Although higher response rates to subsequent systemic treatment (SST) have been described, post-PD outcome data are scarce. OBJECTIVE To examine the outcome of UC patients who received SST and no SST after progressing to ICIs. DESIGN, SETTING, AND PARTICIPANTS A retrospective analysis of UC patients progressing to frontline or later-line anti-PD-1/PD-L1 therapy in 10 European institutions was conducted between March 2013 and September 2017. INTERVENTION Post-PD management as per standard practice. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Overall survival (OS) was analyzed with a Kaplan-Meier model. Cox regression was used for multivariate analysis (MV). Impact of SST on OS was examined with a time-varying covariate model. RESULTS AND LIMITATIONS A total of 270 UC patients with PD to ICIs (69 frontline, 201 later line) were analyzed. Of the patients, 57% of frontline-ICI-PD and 34% of later-line-ICI-PD patients received SST, and SST had an impact on OS in MV (frontline: hazard ratio [HR] 0.22, 95% confidence interval [CI] 0.10-0.51, p < 0.001; later line: HR 0.22, 95% CI 0.13-0.36, p < 0.001). In the frontline-ICI-PD group, median OS with and without SST was 6.8 mo (95% CI 5.0-8.6) and 1.9 mo (95% CI 0.9-3.0), respectively. High disease burden (three or more metastatic sites: HR 2.49, p = 0.03; simultaneous liver/bone metastases: HR 3.93, p = 0.03) predicted worse survival. In later-line-ICI-PD group, response to ICIs (HR 0.37, p = 0.03), longer exposure to ICIs (HR 0.89, p = 0.002), and bone metastasis (HR 2.42, p < 0.001) predicted survival. The retrospective nature of this study and a lack of certain parameters limit the interpretation of our analysis. CONCLUSIONS Patients progressing to frontline ICIs are at risk of early death, excluding them from experiencing potential benefit from chemotherapy PATIENT SUMMARY: Our analysis suggests that outcomes after failing immunotherapy are poor, particularly in UC patients who received no prior chemotherapy.

Trifluoperazine, an Antipsychotic Drug, Effectively Reduces Drug Resistance in Cisplatin-Resistant Urothelial Carcinoma Cells via Suppressing Bcl-xL: An In Vitro and In Vivo Study. Int J Mol Sci 2019; 20:ijms20133218.

Abstract
Cisplatin-based chemotherapy is the primary treatment for metastatic bladder urothelial carcinoma (UC). Most patients inevitably encounter drug resistance and resultant disease relapse. Reduced apoptosis plays a critical role in chemoresistance. Trifluoperazine (TFP), an antipsychotic agent, has demonstrated antitumor effects on various cancers. This study investigated the efficacy of TFP in inhibiting cisplatin-resistant bladder UC and explored the underlying mechanism. Our results revealed that cisplatin-resistant UC cells (T24/R) upregulated the antiapoptotic factor, B-cell lymphoma-extra large (Bcl-xL). Knockdown of Bcl-xL by siRNA resensitized cisplatin-resistant cells to the cisplatin cytotoxic effect. TFP (10–45 μM) alone elicited dose-dependent cytotoxicity, apoptosis, and G0/G1 arrest on T24/R cells. Co-treatment of TFP potentiated cisplatin-induced cytotoxicity in T24/R cells. The phenomenon that TFP alleviated cisplatin resistance to T24/R was accompanied with concurrent suppression of Bcl-xL. In vivo models confirmed that TFP alone effectively suppressed the T24/R xenograft in nude mice. TFP co-treatment enhanced the antitumor effect of cisplatin on the T24/R xenograft. Our results demonstrated that TFP effectively inhibited cisplatin-resistant UCs and circumvented cisplatin resistance with concurrent Bcl-xL downregulation. These findings provide a promising insight to develop a therapeutic strategy for chemoresistant UCs.

Aldo-keto reductase 1C1 induced by interleukin-1β mediates the invasive potential and drug resistance of metastatic bladder cancer cells. Sci Rep 2016; 6:34625.

Abstract
In treating bladder cancer, determining the molecular mechanisms of tumor invasion, metastasis, and drug resistance are urgent to improving long-term patient survival. One of the metabolic enzymes, aldo-keto reductase 1C1 (AKR1C1), plays an essential role in cancer invasion/metastasis and chemoresistance. In orthotopic xenograft models of a human bladder cancer cell line, UM-UC-3, metastatic sublines were established from tumors in the liver, lung, and bone. These cells possessed elevated levels of EMT-associated markers, such as Snail, Slug, or CD44, and exhibited enhanced invasion. By microarray analysis, AKR1C1 was found to be up-regulated in metastatic lesions, which was verified in metastatic human bladder cancer specimens. Decreased invasion caused by AKR1C1 knockdown suggests a novel role of AKR1C1 in cancer invasion, which is probably due to the regulation of Rac1, Src, or Akt. An inflammatory cytokine, interleukin-1β, was found to increase AKR1C1 in bladder cancer cell lines. One particular non-steroidal anti-inflammatory drug, flufenamic acid, antagonized AKR1C1 and decreased the cisplatin-resistance and invasion potential of metastatic sublines. These data uncover the crucial role of AKR1C1 in regulating both metastasis and drug resistance; as a result, AKR1C1 should be a potent molecular target in invasive bladder cancer treatment.

Abstract
Cisplatin-based chemotherapy is the primary treatment for metastatic bladder urothelial carcinoma. However, the response rate is only 40–65%. This study investigated the anti-tumor effect and underlying mechanisms of the combination of cisplatin and the NEDD8-activating enzyme inhibitor MLN4924 in human bladder urothelial carcinoma. The combination of cisplatin and MLN4924 exerted synergistic cytotoxicity on two high-grade bladder urothelial carcinoma cell lines, NTUB1 and T24 (combination index <1). MLN4924 also potentiated the cisplatin-induced apoptosis and activation of caspase-3 and -7, phospho-histone H2A.X and PARP. c-Jun N-terminal kinase (JNK) activation and a down-regulation of B-cell lymphoma-extra large (Bcl-xL) were also observed during cisplatin and MLN4924 treatment. Inhibition of JNK activation partially restored cell viability and Bcl-xL expression. Bcl-xL overexpression also rescued cell viability. MLN4924 significantly potentiated cisplatin-induced tumor suppression in urothelial carcinoma xenograft mice. In summary, MLN4924 synergistically enhanced the anti-tumor effect of cisplatin via an increase in DNA damage, JNK activation and down-regulation of Bcl-xL in urothelial carcinoma cells. These findings provide a new therapeutic strategy for the treatment of bladder cancer.

Abstract
Gemcitabine and cisplatin (GC) has been widely used for advanced and metastatic urothelial carcinoma (UC). However, resistance to this remedy has been noticed. We have demonstrated that increase of TG-interacting factor (TGIF) in specimens is associated with worse prognosis of upper tract UC (UTUC) patients. The roles of TGIF in the gemcitabine resistance of UC were explored. Specimens of 23 locally advanced/advanced stage UTUC patients who received GC systemic chemotherapy after radical nephroureterectomy were collected to evaluate the alterations of TGIF in the resistance to the remedy by using immunohistochemistry. In vitro characterizations of mechanisms mediating TGIF in gemcitabine resistance were conducted by analyzing NTUB1 cells and their gemcitabine-resistant subline, NGR cells. Our results show that increased TGIF is significantly associated with chemo-resistance, poor progression-free survival, and higher cancer-related deaths of UTUC patients. Higher increases of TGIF, p-AKT(Ser473) and invasive ability were demonstrated in NGR cells. Overexpression of TGIF in NTUB1 cells upregulated p-AKT(Ser473) activation, enhanced migration ability, and attenuated cellular sensitivity to gemcitabine. Knockdown of TGIF in NGR cells downregulated p-AKT(Ser473) activation, declined migration ability, and enhanced cellular sensitivity to gemcitabine. In addition, histone deacetylases inhibitor trichostatin A (TSA) inhibited TGIF, p-AKT(Ser473) expression and migration ability. Synergistic effects of gemcitabine and TSA on NGR cells were also demonstrated. Collectively, TGIF contributes to the gemcitabine resistance of UC via AKT activation. Combined treatment with gemcitabine and TSA might be a promising therapeutic remedy to improve the gemcitabine resistance of UC.

Analogs of somatostatin, bombesin/gastrin-releasing peptide (GRP), luteinizing hormone-releasing hormone (LH-RH) and growth hormone-releasing hormone (GH-RH) can interfere with receptors on tumor cells or intracellular pathways that are important in cell proliferation and in this way inhibit tumor growth. The first part of this review explains how these peptide hormones and their analogs affect tumors. The second part of this review describes how various hormone analogs can be used for the treatment of gastric, colorectal, pancreatic, liver and urinary bladder cancers. These tumors are major health problems worldwide and their treatment remains a great challenge. Receptors for somatostatin, bombesin/GRP, LH-RH and GH-RH are present in a large percentage of these cancers. We have developed a series of cytotoxic peptides based on doxorubicin or its derivative 2-pyrrolino-doxorubicin coupled to an analog of LH-RH, somatostatin or bombesin. This new class of targeted analogs might provide a more effective therapy for various cancers that express receptors for these carrier peptides, while producing significantly reduced peripheral toxicity. Under experimental conditions, these peptide hormone analogs strongly inhibited the growth of these tumors. Cytotoxic analogs were particularly effective on tumors that express the specific peptide receptors and acted more powerfully than the carrier peptide or the cytotoxic compound alone. Clinical trials on these peptide analogs are in progress.

Adaptor protein CRK induces epithelial-mesenchymal transition and metastasis of bladder cancer cells through HGF/c-Met feedback loop. Cancer Sci 2015; 106:709-717. [PMID: 25816892 PMCID: PMC4471787 DOI: 10.1111/cas.12662] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2014] [Revised: 03/18/2015] [Accepted: 03/22/2015] [Indexed: 12/15/2022] Open
Abstract
We have previously reported that an adaptor protein CRK, including CRK-I and CRK-II, plays essential roles in the malignant potential of various aggressive human cancers, suggesting the validity of targeting CRK in molecular targeted therapy of a wide range of cancers. Nevertheless, the role of CRK in human bladder cancer with marked invasion, characterized by distant metastasis and poor prognosis, remains obscure. In the present study, immunohistochemistry indicated a striking enhancement of CRK-I/-II, but not CRK-like, in human bladder cancer tissues compared to normal urothelium. We established CRK-knockdown bladder cancer cells using 5637 and UM-UC-3, which showed a significant decline in cell migration, invasion, and proliferation. It is noteworthy that an elimination of CRK conferred suppressed phosphorylation of c-Met and the downstream scaffold protein Gab1 in a hepatocyte growth factor-dependent and -independent manner. In epithelial–mesenchymal transition-related molecules, E-cadherin was upregulated by CRK elimination, whereas N-cadherin, vimentin, and Zeb1 were downregulated. A similar effect was observed following treatment with c-Met inhibitor SU11274. Depletion of CRK significantly decreased cell proliferation of 5637 and UM-UC-3, consistent with reduced activity of ERK. An orthotopic xenograft model with bioluminescent imaging revealed that CRK knockdown significantly attenuated not only tumor volume but also the number of circulating tumor cells, resulted in a complete abrogation of metastasis. Taken together, this evidence uncovered essential roles of CRK in invasive bladder cancer through the hepatocyte growth factor/c-Met/CRK feedback loop for epithelial–mesenchymal transition induction. Thus, CRK might be a potent molecular target in bladder cancer, particularly for preventing metastasis, leading to the resolution of clinically longstanding critical issues.

Controversies in the treatment of invasive urothelial carcinoma: a case report and review of the literature. BMC Urol 2015; 15:15. [PMID: 25887442 PMCID: PMC4361131 DOI: 10.1186/s12894-015-0008-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2014] [Accepted: 02/16/2015] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND More than 429,000 patients worldwide are diagnosed with bladder cancer each year and muscle-invasive bladder cancer has an especially poor outcome. The median age at diagnosis is over 70 years, and many patients also have a substantial number of age-associated impairments that need to be considered when planning therapeutic interventions. CASE PRESENTATION Here, we report the case of a 63-year-old man with a cT3b urothelial carcinoma which was surgically removed. No neoadjuvant or adjuvant chemotherapy was administered. After 18 months a lung metastasis was confirmed and resected but no chemotherapy was given after surgery. Twelve months later, the patient relapsed and was treated with a combination of gemcitabine and cisplatin and after a decline in renal function the treatment was changed to a combination of carboplatin and gemcitabine which resulted in a partial response which lasted 8 months. Following this vinflunine was administered as a second line treatment. Here we review the evidence available in the literature regarding the suitability of different treatment options for managing muscle-invasive bladder cancer at each step of the case presentation. CONCLUSION Bladder cancer treatment requires a multidisciplinary approach. Although, depending on the clinical characteristics of the patient, there are some controversial points in the management of this pathology we hope that the scientific data and the clinical trials reviewed in this case report, can help to guide physicians to make more rational decisions regarding the management of these patients.

Abstract
We evaluated primary tumors from two cohorts, Spain (N = 111) and Greece (N = 102), for patients who were treated with platinum-based chemotherapy. Patients were tested for HER2 status (IHC score of 3+ or FISH ratio of ≥ 2.2) by immunohistochemistry (IHC), fluorescence in situ hybridization (FISH), DNA copy number, mRNA expression, and mutation status in patients with metastatic urothelial carcinoma (UC), and its impact on survival. ERBB2 mutation was determined by hotspot sequencing. mRNA expression was assessed using NanoString counting. Association of overall survival (OS) and HER2 status was assessed by a Cox regression model. NIH-3T3 cells containing HER2 V777L were assessed for growth, invasion, and HER2 kinase activation. In all, 22% of Spanish and 4% of Greek cohorts had 3+ HER2 staining by IHC. FISH amplification was identified in 20% of Spanish and 4% of Greek cohorts. Kappa coefficient between FISH and IHC was 0.47. HER2 status was not associated with OS in univariate (Spanish P = 0.34; Greek P = 0.11) or multivariate (Spanish P = 0.49; Greek P = 0.12) analysis. HER2-positive tumors expressed higher levels of HER2 mRNA than HER2-negative tumors (P < 0.001). HER2 mutations (V777L and L755S) were identified in two (2%) patients. In vitro analysis of V777L results in transformation of NIH-3T3 cells, leading to increased growth, invasion on soft agar, and HER2 kinase constitutive activation. In summary, HER2 overexpression or amplification in the primary tumor did not predict OS in patients with metastatic UC. HER2 positivity rates can differ between different populations. Further trials in genomically screened patients are needed to assess HER2-targeted therapies in UC.

Abstract
It has been shown that chemotherapy has limited antitumor activity against advanced urothelial bladder cancer (UBC). Consequently, there is an urgent need to develop effective therapeutic methods for patients with advanced UBC. In the present study, the inhibitory effects of lentinan alone, gemcitabine alone, or lentinan combined with gemcitabine on the proliferation of the UBC cell line, T24, were investigated. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay, annexin V fluorescein isothiocyanate/propidium iodide staining, and flow cytometry were used to determine the proliferation and apoptosis of T24 cells in each treatment group. Survival-related protein expression was analyzed by western blotting. Increased concentrations of lentinan, or lentinan combined with gemcitabine, positively correlated with decreased T24 cell proliferation. Lentinan combined with gemcitabine chemotherapy significantly inhibited UBC cell proliferation. Gemcitabine has the ability to induce T24 cell apoptosis, and this effect is enhanced when it is combined with lentinan.

Abstract
OBJECTIVE To determine whether neoadjuvant chemotherapy (NAC) is a predictor of postoperative complications, length of stay (LOS), or operating time after radical cystectomy (RC) for bladder cancer. PATIENTS AND METHODS A retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was performed to identify patients receiving NAC before RC from 2005 to 2011. Bivariable and multivariable analyses were used to determine whether NAC was associated with 30-day perioperative outcomes, e.g. complications, LOS, and operating time. RESULTS Of the 878 patients who underwent RC for bladder cancer in our study, 78 (8.9%) received NAC. Excluding those patients who were ineligible for NAC due to renal insufficiency, 78/642 (12.1%) received NAC. In all, 457 of the 878 patients (52.1%) undergoing RC had at least one complication ≤30 days of RC, including 43 of 78 patients (55.1%) who received NAC and 414 of 800 patients (51.8%) who did not (P = 0.58). On multivariable logistic regression, NAC was not a predictor of complications (P = 0.87), re-operation (P = 0.16), wound infection (P = 0.32), or wound dehiscence (P = 0.32). Using multiple linear regression, NAC was not a predictor of increased operating time (P = 0.24), and patients undergoing NAC had a decreased LOS (P = 0.02). CONCLUSIONS Our study is the first large multi-institutional analysis specifically comparing complications after RC with and without NAC. Using a nationally validated, prospectively maintained database specifically designed to measure perioperative outcomes, we found no increase in perioperative complications or surgical morbidity with NAC. Considering these findings and the well-established overall survival benefit over surgery alone, efforts are needed to improve the uptake of NAC.

Temsirolimus improves cytotoxic efficacy of cisplatin and gemcitabine against urinary bladder cancer cell lines. Urol Oncol 2013; 32:41.e11-22. [PMID: 24035472 DOI: 10.1016/j.urolonc.2013.04.012] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2013] [Revised: 04/25/2013] [Accepted: 04/26/2013] [Indexed: 12/26/2022]
Abstract
OBJECTIVES To analyze the cytotoxic action of temsirolimus using 3 established human bladder cancer cell lines and to assess whether temsirolimus potentiates the anticancer activity of gemcitabine and cisplatin. METHODS Temsirolimus (500, 1,000, 2,000, and 4,000 nM), in isolation, and combined with gemcitabine (100 nM) and cisplatin (2.5 µg/ml), was given to 5637, T24, and HT1376 bladder cancer cell lines. Cell proliferation, autophagy, early apoptosis, and cell cycle distribution were analyzed after a 72-hour period. The expression of mammalian target of rapamycin baseline, Akt, and their phosphorylated forms, before and after treatment with temsirolimus, was evaluated by immunoblotting. RESULTS Temsirolimus slightly decreased the bladder cancer cell proliferation in all 3 cell lines. No significant differences in the expression of mammalian target of rapamycin, Akt, and their phosphorylated forms because of temsirolimus exposure were found in the 3 cell lines. As part of a combined regime along with gemcitabine, and especially with cisplatin, there was a more pronounced antiproliferative effect. This pattern of response was similar to the other parameters analyzed (increased autophagy and apoptosis). Also, in the combined regime, an enhanced cell cycle arrest in the G0/G1 phase was observed. The non-muscle invasive 5637 bladder cancer cell line was most sensitive to both combinations. CONCLUSIONS Temsirolimus makes a moderate contribution in terms of cell proliferation, apoptosis, and autophagy. However, it does potentiate the activity of gemcitabine and particularly cisplatin. Therefore, cisplatin- or gemcitabine-based chemotherapy regimen used in combination with temsirolimus to treat bladder cancer represents a novel and valuable treatment option, which should be tested for future studies in urinary bladder xenograft models.

Abstract
Cisplatin (CDDP)-based chemotherapy is a commonly treatment for advanced urothelial carcinoma. However, episodes of cisplatin resistance have been referenced. Recently it has been reported that everolimus (RAD001) could have an important role to play in bladder-cancer treatment and that mTOR inhibitors may restore chemosensitivity in resistant tumours. The aim of this study was to assess RAD001 in vitro ability to enhance CDDP cytotoxicity in three human bladder-cancer cell lines. Over the course of 72h, the cells were exposed to different concentrations of CDDP and RAD001, isolated or combined. Treatment with CDDP statistically (P<0.05) decreased cell proliferation in cell lines in a dose-dependent manner. The anti-proliferative activity of CDDP used in combination with RAD001 was statistically significant (P<0.05) in the cell lines at all concentrations tested. RAD001 had a therapeutic effect when used in combination with CDDP and could therefore be a useful anti-cancer drug combination for patients with bladder cancer.

Abstract
Many bladder cancers progress to invasion with poor prognosis; new therapeutic methods are needed. We developed a cytotoxic LH-RH analog, AN-152 (AEZS-108) containing doxorubicin (DOX), for targeted therapy of cancers expressing LHRH receptors. We investigated the expression of LH-RH receptors in clinical bladder cancers and in HT-1376, J82, RT-4 and HT-1197 human bladder cancer lines. The effect of analog, AN-152, on growth of these tumor lines xenografted into nude mice was analyzed. Using molecular and functional assays, we also evaluated the differences between the effects of AN-152, and DOX alone. We demonstrated the expression of LH-RH receptors on 18 clinical bladder cancers by immunohistochemistry and on four human urinary bladder cancer lines HT-1376, J82, RT-4 and HT-1197 by Western blotting and binding assays. AN-152 powerfully inhibited growth of these bladder cancers in nude mice. AN-152 exerted greater effects than DOX and was less toxic. DOX activated strong multidrug resistance mechanisms in RT-4 and HT-1197 cancers, while AN-152 had no or less such effect. PCR assays and in vitro studies revealed differences in the action of AN-152 and DOX on the expression of genes involved in apoptosis. These results suggest that targeted cytotoxic LH-RH analog, AN-152 (AEZS- 108), should be examined for treatment of patients with LH-RH receptor positive invasive bladder cancers.

Abstract
A variety of cancer stem-like cells (CSCs) have been shown to be responsible for cancer tumorigenicity, relapse and metastasis. Despite several reports demonstrating the presence of CSCs in human bladder cancer, their identities are still under debate, and few studies have examined their roles in cisplatin resistance and related tumor progression. In this study, a subpopulation of CSCs was enriched following cisplatin selection from the bladder cell line T24. The cisplatin-resistant T24 cells displayed a greater self-renewal capacity as demonstrated by higher levels of sphere formation and stem cell marker expression, contained a larger proportion of side population cells and exhibited higher tumorigenicity. They also possessed epithelial-mesenchymal transition characteristics. Furthermore, a strong correlation between the levels of Bmi1 and Nanog expression and the degree of malignancy of urothelial cell carcinomas tissues was observed. We provide the first direct evidence that CSC-like cells exist in the population of cisplatin-resistant bladder cancer cells and may play a role in the progression and drug resistance of bladder cancer.

Abstract
Muscle-invasive bladder cancer is an aggressive disease with at least 50% of patients dying from metastases within 2 years of diagnosis. The 5-year survival rate for metastatic bladder cancer is <15%. Although modern combination chemotherapy regimens have improved median survival from 6 to 14 months compared with best supportive care, there is still a great opportunity for improvement. New therapies and strategies for better patient and treatment selection are now being investigated for advanced bladder cancer. These include agents that target several pathways involved in the pathogenesis of the disease--such as growth factor receptors, angiogenic pathways, p53, cell cycle checkpoints and apoptosis--as well as novel chemotherapeutic agents. Results from recent and ongoing trials suggest that some of these agents could soon emerge as useful players to overcome the limitations of our present therapies.

Abstract
Urothelial cancer of the bladder is the 4th most common malignancy in American men and the 9th most common in women. Although it is a chemosensitive disease, advanced bladder cancer seems to have reached a plateau with regard to median survival of patients. Standard first-line therapy remains gemcitabine plus cisplatin (gc) or methotrexate, vinblastine, doxorubicin, and cisplatin (mvac). In patients deemed unfit to receive cisplatin, gemcitabine plus carboplatin or gemcitabine plus paclitaxel can be considered. To date, no standard therapy has been established for patients who recur or are refractory to first-line therapy. Second-line vinflunine, by way of superiority over best supportive care, has shown promise in a phase iii trial. Cisplatin-based therapy (mvac or gc) can also be offered to patients previously treated with cisplatin, especially if they responded previously and are considered platinum-sensitive. Novel targeted therapies are sorely needed to further improve the delivery and efficacy of chemotherapy.

Abstract
After decades of research using a candidate gene approach, only NAT2 and GSTM1 have consistently been demonstrated to be germline genetic susceptibility markers for urinary bladder cancer (UBC). The recent shift to an agnostic genome-wide association approach led to the identification of several UBC susceptibility loci, and provided valuable leads for new mechanistic insights into UBC carcinogenesis. The markers do not have sufficient discriminatory ability yet to be applied for risk assessment in the population and the question is whether they ever will. Prognostic and predictive studies in UBC are still in their infancy compared with etiologic studies. In the future, focus on a genome-wide association approach possibly using whole-genome sequence data, consortia formation and meta-analyses, and blood and tumor tissue collection, preferably in the context of randomized controlled trials will stimulate well designed and sufficiently powered studies, and thereby enhance the elucidation of genetic prognostic and predictive markers.

Abstract
BACKGROUND Genitourinary (GU) cancers are a major healthcare issue in modern oncology. In the last decade many efforts have been made to develop new treatment options but with the possible exception of renal cell carcinoma, very few steps ahead have been taken. At the same time, a wide variety of molecular markers, potentially helpful in identifying patient subpopulation most likely to benefit from a specific treatment have been identified. Our goal is to clarify if biomarkers could be used at present to personalize treatment for GU cancers. MATERIALS AND METHODS Literature was search using PubMed and EMBASE using different terms and combinations regarding possible prognostic and predictive markers in renal, prostate and urothelial cancers. RESULTS 3546 articles were retrieved. After excluding duplications, preclinical studies and factors without possible predictive value 654 publications remain. N-telopeptide, HER2/neu, EGFR, and p53 in prostate cancer, sVEGF-A for RCC and EMMPRIN and Survivin in urothelial cancer were among those identified. After a careful examination of published data, none of them reached a sufficient evidence to be suggested for use outside of clinical trials. CONCLUSIONS To date any reliable biomarkers has been validated for tailored treatments approaches in GU cancer. Future studies focusing on this issue are urgently needed.

Abstract
Objective Second-line treatment options in advanced urothelial cancer are limited. We investigated the efficacy of a methotrexate/vinblastine/doxorubicin/cisplatin (MVAC) combination after failure of gemcitabine/platinum chemotherapy. Patients and methods Twenty-five patients with advanced urothelial cancer, who received second-line MVAC after first-line gemcitabine/cisplatin (n = 9) or gemcitabine/carboplatin (n = 16), were included in this retrospective analysis. Results Twenty-two patients (88%) relapsed within 6 months after first-line treatment. Following MVAC, there were 5 (20%) objective responses. Median follow-up was 20.2 months. Median progression-free survival (PFS) was 3.8 months (95% CI: 2.3–5.2), and median overall survival (OS) was 9 months (95% CI: 6.6–11.4). Eastern Cooperative Oncology Group performance status 0.1 versus 2 was associated with longer PFS (5 months versus 3.3 months, P = 0.049). Response or stabilization of disease during second-line chemotherapy predicted for a significantly longer PFS and OS (7.4 versus 3.5, P = 0.005; 15.5 versus 7, P = 0.046). Conclusions Second-line MVAC chemotherapy may result in prolonged survival in some patients with refractory disease. Further research in this field is necessary.

Abstract
Advanced bladder cancer is a disease with a high recurrence rate and metastatic capacity exhibiting a poor outcome. The pathologic stage and nodal involvement are independent prognostic factors for survival after cystectomy, and in locally advanced or metastatic disease, the performance status and the presence of visceral metastases have been correlated with treatment outcome. The regimen methotrexate-vinblastine-adriamycin-cisplatin (MVAC) has been the treatment of choice for decades and later the combination of cisplatin with gemcitabine became also the new standard of care, by demonstrating a more favorable toxicity profile. Also, carboplatin-gemcitabine and taxanes have been useful alternatives for patients unfit for cisplatin-based treatment. Additionally, the evaluation of certain chemotherapeutic agents has produced promising results in the second-line setting. Lastly, the past decade has provided information on the molecular mechanism of bladder cancer offering a personalized approach and optimizing the management of the disease.

Abstract
Molecular markers are not established in management of bladder cancer. There is, however, a limit to the ability of clinical and pathological parameters to predict patients at high risk for urothelial carcinoma of the bladder (UCB) recurrence or mortality. The assessment of molecular biomarkers in surgical UCB specimens offers additional information on the biology of the disease, and might improve the prediction of oncologic end points. There is also a potential for molecular biomarkers to predict the response to adjuvant or neoadjuvant therapies. Furthermore, markers may guide targeted therapy. Prospective trials are needed to validate the clinical benefit of assessing expression patterns of molecular biomarkers.

Abstract
Bladder cancer is the fourth most common type of cancer in men (ninth in women) in the United States. Cisplatin is an effective agent against the most common subtype, urothelial carcinoma. However, the development of chemotherapy resistance is a severe clinical problem for the successful treatment of this and other cancers. A better understanding of the cellular and molecular events in response to cisplatin treatment and the development of resistance are critical to improve the therapeutic options for patients. Here, we report that expression of the CCAAT/enhancer binding protein delta (CEBPD, C/EBPdelta, NF-IL6beta) is induced by cisplatin in the human bladder urothelial carcinoma NTUB1 cell line and is specifically elevated in a cisplatin resistant subline. Expression of CEBPD reduced cisplatin-induced reactive oxygen species (ROS) and apoptosis in NTUB1 cells by inducing the expression of Cu/Zn-superoxide dismutase (SOD1) via direct promoter transactivation. Several reports have implicated CEBPD as a tumor suppressor gene. This study reveals a novel role for CEBPD in conferring drug resistance, suggesting that it can also be pro-oncogenic. Furthermore, our data suggest that SOD inhibitors, which are already used as anti-angiogenic agents, may be suitable for combinatorial chemotherapy to prevent or treat cisplatin resistance in bladder and possibly other cancers.

Abstract
PURPOSE The present study sought to identify pretreatment prognostic factors for overall survival (OS) in patients with metastatic transitional cell carcinoma of the urothelial tract (TCCU) who experienced treatment failure with the first-line, platinum-based regimen included in the phase III vinflunine trial. PATIENTS AND METHODS In total, 370 patients with platinum-refractory TCCU were included in this analysis. Potential prognostic factors were recorded prospectively. Univariate analysis was used to identify clinical and laboratory factors that significantly impact survival. Multivariate analysis was used to identify independent prognostic factors, and bootstrap analysis was performed for internal validation, forming a prognostic model. External validation was performed on the phase II vinflunine study CA183001. RESULTS Multivariate analysis and the internal validation identified Eastern Cooperative Oncology Group performance status (PS) more than 0, hemoglobin level less than 10 g/dL, and the presence of liver metastasis as the main adverse prognostic factors for OS. External validation confirmed these prognostic factors. Four subgroups were formed based on the presence of zero, one, two, or three prognostic factors; the median OS times for these groups were 14.2, 7.3, 3.8, and 1.7 months (P < .001), respectively. CONCLUSION We identified and both internally and externally validated three adverse risk factors (PS, hemoglobin level, and liver metastasis) that predict for OS and developed a scoring system that classifies patients with platinum-refractory disease on second-line chemotherapy into four risk groups with different outcome. Similar to the first-line setting, the presence of visceral metastases and poor PS predict a worse prognosis. These factors, together with low hemoglobin, can be used for prognostication and future patient stratification in clinical trials.

Abstract
Chemotherapy continues to be the treatment of choice for advanced/metastatic bladder cancer. Although response rates as high as 70% have been achieved, there continue to be high progression rates and poor long-term survival. Surgical consolidation offers improved outcomes compared with chemotherapy alone, especially in patients who achieve complete clinical response to chemotherapy. The role of radiation and/or surveillance following major response to chemotherapy in patients with advanced disease remains unclear. Gross regional nodal involvement identified at the time of surgery does not preclude radical cystectomy with lymphadenectomy. Retroperitoneal lymph node dissection may be beneficial to select patients with nonregional retroperitoneal nodal metastasis who achieve good clinical response to chemotherapy. Visceral or lung metastasectomy may be offered to patients with solitary metastasis who achieve a good and durable response to chemotherapy. Nonresponders should be either offered a clinical trial (if available), second-line chemotherapy or best supportive care.

Abstract
PURPOSE Novel imaging modalities are needed to detect occult metastatic disease in bladder carcinoma. Patients with regional lymphatic spread could be targeted for neoadjuvant chemotherapy, and patients with distant metastatic disease could be spared the unnecessary morbidity of radical cystectomy. Herein, we report a prospective study of positron emission tomography/computed tomography (PET/CT) with [(18)F]fluorodeoxyglucose (FDG) in patients undergoing radical cystectomy for cT2-3N0M0 urothelial carcinoma of the bladder. METHODS Forty-three chemotherapy-naïve patients underwent FDG-PET/CT before planned cystectomy. All had negative conventional CT and bone scintigraphy before enrollment. Positive FDG-PET/CT was confirmed by percutaneous biopsy or open surgical exploration, whereas negative FDG-PET/CT was confirmed by complete lymphadenectomy. Recurrence-free survival (RFS), disease-specific survival (DSS), and overall survival (OS) were described using the Kaplan-Meier method and compared using log-rank test. RESULTS Median follow-up was 14.9 months (range, 0.4 to 46.1 months). One patient who did not undergo lymphadenectomy was excluded from the pathology data analysis (n = 42), whereas another patient who failed to return for follow-up was excluded from survival analysis (n = 42). FDG-PET/CT demonstrated a positive predictive value of 78% (seven of nine), a negative predictive value of 91% (30 of 33), sensitivity of 70% (seven of 10), and specificity of 94% (30 of 32). RFS, DSS, and OS were all significantly poorer in the patients with positive FDG-PET/CT than in those with negative FDG-PET/CT. CONCLUSION FDG-PET/CT detected occult metastatic disease in seven of 42 patients with negative conventional preoperative evaluations. PET findings were strongly correlated with survival. As such, FDG-PET/CT may help in making treatment decisions before radical cystectomy.
