Bhalla S, Pfail J, Ghodoussipour S. Is There a Role for Surgery in the Treatment of Metastatic Urothelial Carcinoma? J Clin Med 2024; 13:7498. [PMID: 39768421 PMCID: PMC11678103 DOI: 10.3390/jcm13247498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2024] [Revised: 11/13/2024] [Accepted: 12/05/2024] [Indexed: 01/11/2025] Open
Abstract
Purpose: Bladder cancer is one of the most common malignancies worldwide with over 614,000 new cases and 220,000 deaths annually. Five percent of newly diagnosed patients have metastatic disease. Metastatic urothelial carcinoma (mUC) is primarily treated with cisplatin-based chemotherapy, immunotherapy, targeted therapy, or combinations. Cure from disease is rarely achieved, with the overall survival being between 12 and 15 months, and the 5-year survival in the range of 5-15%. Historically, mUC has been deemed surgically incurable. There are limited data available to assess survival benefit with surgical extirpation of the primary site or metastases. In this review, we summarize findings from previous studies regarding the role of surgery in patients with clinically node-positive bladder cancer or metastatic urothelial carcinoma, focusing on cytoreductive radical cystectomy (RC) and distant metastasectomy. Materials and Methods: A literature search was conducted on The Medical Literature Analysis and Retrieval System Online (Medline), Excerpta Medica dataBASE (Embase), preprints, and ClinicalTrials.gov for studies that discussed the role of surgery in patients with clinically node-positive bladder cancer or mUC, focusing on cytoreductive radical cystectomy (RC) and distant metastasectomy. The keywords used included transitional cell carcinoma, urothelial carcinoma, bladder cancer, bladder carcinoma, bladder metastasis, bladder tumor, lymph node metastasis, metastasis, and muscle-invasive bladder cancer. Results: The final analysis included 21 studies, including 17 retrospective reviews, 2 prospective phase II trials, and 2 meta-analyses. Of the studies that assessed patients with urothelial carcinoma (UC) with nodal involvement, 15 of 17 showed improved survival with chemotherapy followed by radical cystectomy (RC). To our knowledge, few studies have solely assessed surgery in patients with distant metastases. Most studies include patients with both UC with local LN involvement and patients with distant sites of metastasis. Of these studies, 12 of 13 indicated improved survival with metastasectomy. Conclusions: While it remains to be seen whether metastasectomy will have a role in patients with mUC, patient selection is an important factor when assessing the survival benefits. Patient characteristics correlated with improved survival include good performance status, good response to chemotherapy, and single site of metastasis. Further studies of mUC patients are required to clearly assess the survival impact of cytoreductive surgery.

Metastatic Organotropism Differential Treatment Response in Urothelial Carcinoma: A Systematic Review and Network Meta-analysis of Randomized Controlled Trials. Eur Urol Oncol 2024; 7:663-676. [PMID: 37980251 DOI: 10.1016/j.euo.2023.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 09/25/2023] [Accepted: 11/03/2023] [Indexed: 11/20/2023]
Abstract
CONTEXT The optimal therapeutic agent with respect to metastatic sites is unclear in advanced urothelial carcinoma (UC). OBJECTIVE To investigate the metastatic organotropism differential treatment response in patients with advanced or metastatic UC. EVIDENCE ACQUISITION A systematic search and network meta-analysis (NMA) was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. The primary endpoints of interest were the objective response rate, overall survival (OS), and progression-free survival with respect to different metastatic sites. EVIDENCE SYNTHESIS Twenty-six trials comprising 9082 patients met our eligibility criteria, and a formal NMA was conducted. Durvalumab plus tremelimumab as first-line systemic therapy was significantly associated with better OS than chemotherapy in visceral metastasis (hazard ratio [HR] 0.81, 95% confidence interval [CI] 0.67-0.98). Pembrolizumab as second-line systemic therapy was significantly associated with better OS than chemotherapy in patients with visceral metastasis (HR 0.75, 95% CI 0.60-0.95). Atezolizumab as second-line systemic therapy was significantly associated with better OS than chemotherapy in patients with liver metastasis (in the population of >5% of tumor-infiltrating immune cells) and lymph node metastasis (HR 0.51, 95% CI 0.28-0.96, and HR 0.59, 95% CI 0.37-0.96, respectively). CONCLUSIONS Administration of immune-oncology treatments with respect to metastatic sites in patients with advanced or metastatic UC might have a positive impact on survival outcomes in both the first- and the second-line setting. Nevertheless, further investigations focusing on metastatic organotropism differential response with reliable oncological outcomes are needed to identify the optimal management strategy for these patients. PATIENT SUMMARY Although the supporting evidence for oncological benefits of therapeutic systemic agents with respect to metastatic sites is not yet strong enough to provide a recommendation in advanced or metastatic urothelial carcinoma, clinicians may take into account tumor organotropism only in discussion with the patient fully informed on the optimal treatment decision to be taken.

[PMID: 37185390 PMCID: PMC10136539 DOI: 10.3390/curroncol30040277] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 03/15/2023] [Accepted: 03/16/2023] [Indexed: 03/29/2023] Open
Abstract
To compare efficacy outcomes for all approved and investigational first-line (1L) treatment regimens for locally advanced or metastatic urothelial carcinoma (la/mUC) with standard of care (SOC), a network meta-analysis (NMA) was conducted. A systematic literature review (SLR) identified phase 2 and 3 randomized trials investigating 1L treatment regimens in la/mUC published January 2001–September 2021. Three networks were formed based on cisplatin (cis) eligibility: cis-eligible/mixed (cis-eligible patients and mixed populations of cis-eligible/ineligible patients), cis-ineligible (strict; exclusively cis-ineligible patients), and cis-ineligible (wide; including studies with investigator’s choice of carbo). Analyses examined comparative efficacy by hazard ratio (HR) for overall survival (OS), and progression-free survival (PFS), and odds ratio (OR) for overall response rate (ORR), with 1L regimens vs. SOC. SOC was gemcitabine + cis (GemCis) or carboplatin (GemCarbo), cis-eligible/mixed network, and GemCarbo cis-ineligible networks. Of 1906 SLR identified citations, 55 trials were selected for data extraction. The NMA comprised 11, 6, and 8 studies in the cis-eligible/mixed, cis-ineligible (strict), cis-ineligible (wide) networks, respectively. In a meta-analysis of SOC control arms, median (95% CI) overall survival (OS) in months varied by network: 13.19 (12.43, 13.95) cis-eligible/mixed, 11.96 (10.43, 13.48) cis-ineligible (wide), and 9.74 (6.71, 12.76) cis-ineligible (strict). Most differences in OS, PFS, and ORR with treatment regimens across treatment networks were not statistically significant compared with SOC. Outcomes with current 1L regimens remain poor, and few significant improvements over SOC have been made, despite inclusion of recent clinical trial data, highlighting an unmet need in the la/mUC patient population.

Urachal carcinoma: The journey so far and the road ahead. Pathol Res Pract 2023; 243:154379.

Abstract
Urachal carcinoma, a rare cancer arising from urachus, accounts for about 1% of bladder cancer. The diagnosis at stage I shows about 63% 5-year survival whereas only 8% of the patients at stage IV shows a 5-year survival. Above 90% of urachal carcinomas are adenocarcinomas and most of the urachal carcinoma cases are invasive, showing a high resemblance to adenocarcinoma of various origins, making it hard for a conclusive diagnosis. Even though inconclusive, immunohistochemistry can play a significant role in identifying urachal carcinoma. Most cases show the biomarkers CK20 and CDX2, whereas CK7 and β-catenin are expressed at a lesser frequency. Due to the few cases available, there is a lack of evidence regarding specific markers differentiating urachal carcinoma from colorectal or primary bladder adenocarcinomas. In addition to immunohistochemistry, genomic characterization is emerging to play a role in the classification and treatment of the disease. Urachal carcinoma has been reported to have a molecular level similarity with colorectal malignancies regarding certain gene expressions. The TP53 mutations inactivating the tumor suppressor can probably be explored as a possible target in treating urachal carcinoma. Additionally, certain targets identified in gastric and breast cancer along with anti-HER2 treatment strategies can be explored. Immuno-oncology utilizes immune checkpoint inhibitors for the treatment of MSI-H tumors whereas a combination of tyrosine kinase inhibitors along with immune checkpoint inhibitors are being studied to treat MSI stable tumors. The article is an in-depth overview of urachal carcinoma addressing the current landscape with an emphasis on the future scenario.

Adverse events of different chemotherapy regimens in the first-line treatment of patients with advanced or metastatic urothelial cancer: A systematic review and network meta-analysis of randomized controlled trials. Semin Oncol 2021; 48:181-192.

Abstract
INTRODUCTION The present systematic review and network meta-analysis (NMA) of randomized controlled trials (RCTs) aimed to compare the mortality rates related to adverse events (AEs) and discontinuation of treatment due to toxicity as well as all AEs of currently used chemotherapy regimens for first-line therapy of advanced or metastatic urothelial carcinoma of the bladder (UCB). MATERIAL AND METHODS The MEDLINE and EMBASE databases were searched for articles published between January 2000 and June 2020 according to the Preferred Reporting Items for Systematic Review and Meta-analysis extension statement for NMA. Eligible studies included RCTs comparing different first-line chemotherapy regimens for treating advanced or metastatic UCB and AEs as outcome measures. A NMA was performed to assess the mortality rates related to AEs and discontinuation of treatment due to toxicity as well as all AEs. RESULTS Fourteen trials comprising 2,615 patients met our eligibility criteria and formal NMAs were conducted. Results revealed that gemcitabine plus carboplatin had the lowest likelihood of mortality related to AEs (P score: 0.8079), while larotaxel plus cisplatin and paclitaxel, cisplatin plus gemcitabine had both a lower toxicity rate leading to discontinuation (P score: 0.7295 and P score: 0.7242, respectively). Compared with gemcitabine plus cisplatin (GC), most chemotherapy regimens were associated with a lower likelihood of thrombocytopenia, anemia, and cardiovascular toxicity. In contrast, most chemotherapy regimens compared with GC were associated with a higher likelihood of neutropenia, central (fatigue, neuropathy) and gastrointestinal AEs, infections, as well as renal and pulmonary toxicities. CONCLUSION Results of the present study demonstrated that hematological toxicity was the most prevalent AE associated with gemcitabine-containing regimens, while central AEs and febrile neutropenia were more commonly in taxane-containing regimens. GC had the lowest rate of gastrointestinal AEs, infection disorders, and pulmonary toxicities. Cisplatin-containing regimens were associated with a higher rate of renal and cardiovascular toxicity. These differential AEs may help in the detection of the personalized therapy in addition of efficacy data.

Abstract
The Urologic Oncology Journal was founded 25 years ago and we reviewed the literature since that time in the area of urothelial cancer to see the progress and pitfalls we have made over this time period. A comprehensive literature search was conducted by the authors involved who are all actively involved in research, clinical trials, and treatment for urothelial cancer and the results were summarized over the past 25 years. The field of urothelial cancer has evolved tremendously in the last 25 years with the incorporation of molecular subtyping, novel imaging, immunotherapy, and robotic surgery. However, treatments such as BCG and radical cystectomy have remained steadfast over the last 25 years. Although we have a better understanding of the biology of bladder cancer, we still have a long way from being able to cure patients with bladder cancer and eliminate morbidity from treatments. Nevertheless, considerable progress has been made since the founding of the Urologic Oncology Journal 25 years ago.

Abstract
Cancer cells are disordered by nature and thus featured by higher internal redox level than healthy cells. Redox imbalance could trigger programmed cell death if exceeded a certain threshold, rendering therapeutic strategies relying on redox control a possible cancer management solution. Yet, various programmed cell death events have been consecutively discovered, complicating our understandings on their associations with redox imbalance and clinical implications especially therapeutic design. Thus, it is imperative to understand differences and similarities among programmed cell death events regarding their associations with redox imbalance for improved control over these events in malignant cells as well as appropriate design on therapeutic approaches relying on redox control. This review addresses these issues and concludes by bringing affront cold atmospheric plasma as an emerging redox controller with translational potential in clinics.

Abstract
Urothelial carcinoma (UC) is a highly lethal malignancy in the metastatic state. Platinum-based chemotherapy regimens have been the backbone treatment for patients with advanced UC in the first-line setting. However, a large subset of patients are suboptimal candidates for these combinations owing to poor renal function and/or other comorbidities. Patients who are unable to tolerate or who progress after frontline platinum chemotherapy face a poor outcome. Recent insights into UC biology and immunology are being translated into new therapies for metastatic UC (mUC) including immune checkpoint inhibitors (ICIs), erdafitinib, a FGFR inhibitor, and antibody drug conjugates (ADC) such enfortumab vedotin.

Abstract
BACKGROUND Patients with advanced urothelial carcinoma (UC) have poor outcomes, with 5-year survival rates of <5% for those with metastatic, stage IV disease. We have reviewed current treatment paradigms and emerging treatment options for these patients. METHODS The websites of seven national or international organizations were searched for metastatic UC treatment guidelines. Systematic literature reviews were conducted to identify evidence from randomized controlled trials (RCTs) of chemotherapy for patients with previously untreated, unresectable, stage IV UC. Searches included congress databases and articles published between 1990 and 2018. In order to align with the latest treatment paradigms in first-line advanced UC, a focused literature search was conducted to identify evidence supporting immuno-oncology (IO) agents. RESULTS For advanced UC, guidelines universally recommend cisplatin-based chemotherapy as first-line treatment for eligible patients and carboplatin-based regimens for those unfit to receive cisplatin. Despite the evaluation of a number of different cytotoxic regimens over the years, including triplet combinations, survival outcomes have not improved markedly with chemotherapy. Median overall survival with standard of care chemotherapy is ~13 months. Based on the results of single-arm, phase II studies, recent treatment guidelines have included atezolizumab (anti-PD-L1) and pembrolizumab (anti-PD-1) as first-line options for cisplatin-ineligible patients whose tumors express high levels of PD-L1. However, emerging evidence from RCTs of IO agents, including both cisplatin-eligible and cisplatin-ineligible patients, suggest that survival times exceeding 20 months are possible. CONCLUSIONS After having reached a plateau with chemotherapy, the treatment landscape for advanced UC is evolving. Survival outcomes for patients with advanced UC are improving with treatment modalities involving IO agents.

Abstract
Background: Gemcitabine plus cisplatin (GC) and methotrexate, vinblastine, adriamycin, and cisplatin (MVAC) have been the first-line treatments for advanced or metastatic urothelial carcinoma (AMUC). However, their effects are unsatisfactory, and more drugs and regimens still need to be explored. Objective: We aimed to comprehensively compare all possible regimens with GC or MVAC in randomized controlled trials (RCTs) by network meta-analysis. Methods: We searched the PubMed, Embase, and Cochrane databases for RCTs that evaluated regimens compared to GC or MVAC on AMUC patients. The major outcomes were progression-free survival (PFS), overall survival (OS), and objective response rate (ORR). A network meta-analysis was used to assess the effectiveness and safety of the included treatment regimens, and the regimens were then clustered by the average linkage method. Results: A total of 19 trials that assessed 3,363 AMUC patients were included. For PFS, paclitaxel plus GC (PGC) was significantly superior to GC (log hazard ratio (HR): −0.16; 95% confidence interval (CI): −0.32, 0.00) with a moderate level of reliability. However, there was no significant difference between PGC and MVAC (log HR: −0.03; 95% CI: −0.27, 0.20). For OS, PGC was significantly superior to GC (log HR:−0.17; 95% CI: −0.33, −0.00) with a moderate reliability level but not significantly different from MVAC (log HR: −0.10; 95% CI: −0.35, 0.15). Analysis of ORR showed that PGC was superior to MVAC (log odds ratio (OR): 0.59; 95% CI: 0.02, 1.16) with a low reliability level and GC (log OR: 0.41; 95% CI: 0.12, 0.71) with a moderate reliability level. In the cluster results, PGC and sorafenib plus GC (GCS) exhibited relative advantages in efficiency, followed by MVAC and apatorsen plus GC (GCA); however, PGC, gemcitabine plus carboplatin (GP), and MVAC had more serious side effects. Conclusions: In our analysis, PGC was superior to MVAC and GC in only the ORR results and superior to GC in the OS and PFS results but was not significantly different from MVAC. More individualized therapies with targeted drugs need to be studied.

Abstract
PURPOSE OF REVIEW The aim of this review is to sum up the state of the art of urachal carcinoma (UC) in order to easily guide clinicians. RECENT FINDINGS UC is a rare and aggressive disease with consequent few data about diagnosis and treatment. Dates are mainly based on retrospective trial and case reports with limited prospective trial. Clinical presentation is not specific, often with urinary symptoms. Diagnosis is mainly based on CT scan and MRI, useful to evaluate local invasion and nodal status and to detect the presence of distant metastases. Therefore, biopsy is needed to obtain histological confirmation. Surgery is the gold standard for localized disease, while different chemotherapy schemes have been used in metastatic setting. Novel findings based on mutational analysis of the tumor include the use of biological treatment, such as cetuximab, and immunotherapy, such as atezolizumab, with satisfactory responses, suggesting that personalized treatment could be the most suitable option for UC.

Abstract
Background: Bladder cancer remains a cancer type in need of novel and alternative therapies. While multiple inhibitors of EGFR have been evaluated for efficacy in bladder cancer, the results have largely been disappointing with few patients responding to these therapies. Yet, there is a subset of patients that positively responds to EGFR inhibition with tumor shrinkage, indicating it is an effective treatment for a targeted set of bladder tumors. Objective: To derive a gene expression signature capable of predicting the response to EGFR inhibition in bladder cancer cell lines. Methods: he response to cetuximab for 68 colorectal cancer patients was used as training data to generate a gene expression signature. We applied this signature to bladder cancer cell lines and predictions were compared to the responses to seven EGFR inhibitors. Results: A novel 67-gene signature derived from colorectal cancer was able to significantly identify bladder cancer cell lines by their response to several EGFR inhibitors. Conclusions: The 67-gene signature can determine bladder cancer cell line sensitivity to EGFR inhibition. This work demonstrates a preclinical strategy to identify bladder cancer cell lines for EGFR-targeted therapy.

Abstract
Urothelial carcinoma is the sixth most common malignancy in the United States. Although most are diagnosed with non-muscle-invasive malignancy, many patients will develop recurrent disease within 5 years, with 10% to 20% developing advanced muscle-invasive or more distant incurable disease. For such patients, clinical outcomes have remained suboptimal, although recent therapeutic advances have brought new hope to the field. Here, we discuss the main systemic treatment options available for the treatment of patients with advanced disease. This review begins with traditional chemotherapy, which remains a first-line treatment option for many patients. The second section focuses on the evolving landscape of immunotherapy, specifically on approved checkpoint inhibitors and future challenges. Last, we address advances in targeted treatments, including angiogenesis and fibroblast growth factor receptor (FGFR) inhibitors as well as antibody-drug conjugates. As the number of available treatment options continues to expand, ongoing trials to investigate the best sequence and combination strategies to incorporate these drugs into clinical practice will help delineate the future.

Abstract
Immunotherapy has been used in localized urothelial carcinoma for decades, especially in the treatment of superficial disease, in which instillation of BCG is a commonly used treatment option. Clinical investigations based on new insights into the immunogenic potential of metastatic urothelial carcinoma have led to the accelerated FDA approval of the immune checkpoint inhibitors atezolizumab, nivolumab, durvalumab, avelumab, and pembrolizumab. Preliminary findings suggest additional benefits of combinations of immunotherapeutic agents as a future treatment approach in metastatic urothelial carcinoma. Treatment experience with immunotherapy suggests that these drugs are associated with a unique spectrum of immune-related adverse events and specific immune-related patterns of response, including cases of pseudoprogression, which could impede the optimal use of immune checkpoint inhibitors in the clinic. Appropriate management of immune-related adverse events and a greater awareness of immune-mediated response patterns will help to inform treatment decisions and improve patient outcomes; predictive biomarkers of response might facilitate selection of patients who are most likely to respond to and benefit from these exciting new treatments.

Abstract
CONTEXT Immunotherapies promote anticancer responses with varying levels of success based on the tumor type. OBJECTIVE In this narrative review article, we searched the literature regarding immunotherapies in genitourinary malignancies to define the state of the field, explore future applications of immune checkpoint inhibitors, cytokines, vaccines, and cellular therapies in urological oncology and evaluate possible strategies to improve the selection of patients who might benefit from such approaches. EVIDENCE ACQUISITION We reviewed related literature, with a focus on recent studies about immunotherapies, predictors of response, and ongoing clinical trials. EVIDENCE SYNTHESIS Immunotherapies based on immune checkpoint blockade are approved as first- and second-line therapies for urothelial carcinoma (UC) and second-line therapies for renal cell carcinoma with limited success in prostate cancer. Programmed death-ligand 1 is the most commonly used predictive biomarker outside of UC; however, a substantial proportion of patients with tumors negative for programmed death-ligand 1 expression benefit from checkpoint inhibition, limiting its sensitivity. A high mutational load and molecular subtypes of UC are emerging as additional potential predictors. Genomic sequencing and gene expression analysis associate alterations of genes implicated in DNA repair pathways, such as BRCA1 and BRCA2, with immune checkpoint therapies. In prostate cancer, the vaccine, sipuleucel-T, is the only Food and Drug Administration-approved immunotherapy. CONCLUSIONS Immunotherapies are emerging as exciting new treatment options with a tolerable toxicity profile in urological cancers. Checkpoint inhibitors are effective only in a subset of patients, demanding personalized approaches that consider various clinical and molecular parameters to predict patient response. Clinical trials investigating the optimal timing, sequence, and combination of immunotherapies with standard of care and novel agents will guide therapy choices and improve patient outcome. PATIENT SUMMARY Clinical data supports the safety and efficacy of immune checkpoint inhibitors alone or in combination with other therapies in urological cancers.

Abstract
Immune checkpoint inhibition will be the first treatment breakthrough in recurrent and metastatic urothelial carcinoma since the introduction of combination chemotherapy more than 30 years ago. Monoclonal antibodies that target cytotoxic T-lymphocyte antigen 4, programmed death receptor 1, and programmed death receptor ligand 1 are furthest along in clinical development. Specific antibodies targeting either programmed death receptor 1 or programmed death receptor ligand 1 have demonstrated significant single-agent activity with impressive safety and tolerability for heavily pretreated patients in early-phase clinical trials. In our review, we discuss the rationale for immunotherapy in urothelial cancer, completed and ongoing studies with immune checkpoint therapy, the development of molecular subtypes of urothelial carcinoma with the potential impact of immunotherapy in these new groupings, and future directions of exploration with these agents in both early- and late-stage disease.

Abstract
Locally advanced (T3b, T4 and N1-N3) and metastatic urothelial bladder cancer (BCa) is a lethal disease with poor survival outcomes. Combination chemotherapy remains the treatment of choice in patients with metastatic disease and an important part of treatment in addition to radical cystectomy (RC) in patients with locally advanced tumour. Approximately half of patients who underwent RC for muscle invasive BCa relapse after surgery with either local recurrence or distant metastasis. This review focuses on the management of muscle invasive, locally advanced and metastatic BCa with emphasis on the role of surgery; to summarize the current knowledge in order to enhance clinical decision-making and counselling process.

Could salvage surgery after chemotherapy have clinical impact on cancer survival of patients with metastatic urothelial carcinoma? Int J Clin Oncol 2011; 18:110-5.

Abstract
BACKGROUND The clinical impact of salvage surgery after chemotherapy on cancer survival of patients with metastatic urothelial carcinoma is controversial. We aimed to verify the clinical role of salvage surgery by analyzing the long-term outcome in patients with urothelial carcinoma treated by chemotherapy. METHODS Between 2003 and 2010 at a single institution, 31 of 47 patients (66%) with metastatic urothelial carcinoma showed objective responses (CR in 4, PR in 27) after multiple courses of cisplatin/gemcitabine/paclitaxel-based chemotherapy, and a cohort of patients with partial response (PR) were retrospectively enrolled. Twelve (10 male and 2 female, median age 64.0 years) of 27 patients with PR underwent salvage surgeries after the chemotherapy: metastatectomy of residual lesions (10 retroperitoneal lymph nodes, 2 lung), and 6 radical surgeries for primary lesions as well. Progression-free survival and overall patient survival rates were analyzed retrospectively and compared with those of patients without salvage surgery. RESULTS All 12 patients achieved surgical CR. Pathological findings of metastatic lesions showed viable cancer cells in 3 patients. In univariate analysis, sole salvage surgery affected overall survival in 27 patients with PR to the chemotherapy (P = 0.0037). Progression-free survival and overall survival rates in patients with salvage surgery were better than those in 15 PR patients without the surgery (39.8 vs. 0%, and 71.6 vs. 12.1% at 3 years, P = 0.01032 and 0.01048; log-rank test). CONCLUSIONS Salvage surgery for patients with residual tumor who achieve partial response to chemotherapy could have a possible impact on cancer survival.

Abstract
Urothelial carcinoma of the bladder exists as a spectrum of clinical states ranging from non-muscle-invasive to muscle-invasive to advanced/metastatic disease. Each clinical state is associated with a unique tumor biology, prognosis, and approach to treatment. The field of personalized medicine offers the promise to individualize therapeutic decisions in each clinical state with the goal of preventing or delaying progression to more advanced disease states while optimizing quality of life. This review will discuss bladder cancer as a paradigm for the development of personalized cancer medicine, focusing on recent efforts, current challenges, and future opportunities.

Abstract
BACKGROUND The prognosis for unresectable, locally advanced or metastatic transitional cell carcinoma of the bladder is poor with most patients succumbing to their disease within 2 to 3 years. Clinical management at this stage of the disease is palliative with systemic chemotherapy the main treatment of choice. A number of cytotoxic agents have shown activity in metastatic disease including cisplatin, methotrexate, doxorubicin and vinblastine. However, response rates still need improving and toxicities may sometimes be severe, and so the search for newer agents with improved benefit-to-risk ratios is constantly being pursued. One such agent that shows promise is gemcitabine. OBJECTIVES Evaluate the effectiveness and toxicity of gemcitabine for the management of unresectable, locally advanced or metastatic bladder cancer. SEARCH STRATEGY A search strategy was developed for MEDLINE to identify randomised trials of gemcitabine for the treatment of unresectable, locally advanced or metastatic bladder cancer. The searches were from 1966 to July 2010. Other databases searched included EMBASE, CINAHL, the Cochrane Database of Systematic Reviews, LILACS, and the Web of Science®. There were no language or location restrictions. SELECTION CRITERIA The titles and abstracts of the combined electronic and hand searching searches were manually screened by two authors to determine if they met the inclusion criteria of this review. Studies were selected if they were randomised, controlled trials or quasi-randomised clinical trials that included gemcitabine in at least one arm of a comparative study. DATA COLLECTION AND ANALYSIS Data extraction was carried out in duplicate by two authors. The information retrieved included the author's details, the study design, the characteristics of the recruited patients, details of the interventions and data relating to the primary and secondary outcomes measures. MAIN RESULTS Three randomised trials used gemcitabine plus cisplatin (GCis) as one of the arms in each trial. The first randomised trial compared GCis with MVAC (methotrexate, vinblastine, doxorubicin and cisplatin) and showed no significant difference in overall survival (hazard ratio1.09, 95% CI 0.88 to 1.34, P = 0.443) however the GCis regime had fewer incidences of neutropenic sepsis (1% versus 12%, P = 0.001) and mucositis (1% versus 22%, P = 0.001). A second randomised trial compared GCis to gemcitabine plus carboplatin (GCarbo) and reported an improved, but non-significant 1-year survival rate with GCis (64% versus 37%). A third randomised trial compared GCis with gemcitabine plus cisplatin plus paclitaxel (GCisPac) and again found no significant difference in overall survival (respective medians 49 weeks versus 61 weeks).One randomised trial evaluated GCarbo against methotrexate plus carboplatin plus vinblastine (MCarboV) in patients "unfit" for cisplatin-based chemotherapy. There were more overall responses (38% versus 20%) and less severe acute toxicities (14% versus 23%) with GCarbo.In one randomised study evaluating 3-weekly gemcitabine plus paclitaxel (GPac3) versus a 2-weekly regimen overall survival was not significantly different (respective medians 13 and 9 months) however toxicities were worse with GPac3 especially alopecia (76% versus 32%).A larger trial compared gemcitabine (1 g/m(2)) (grams per metre squared) plus paclitaxel (175 mg/m(2)) (milligrams per metre squared) as a 3-weekly schedule for 6 cycles with a 2-weekly maintenance schedule. There was no significant difference in response rates, progression-free survival, disease-specific survival, and overall survival. AUTHORS' CONCLUSIONS A review of the published evidence found that one trial reported gemcitabine plus cisplatin had a better safety profile than MVAC and may be considered the first choice for treatment of metastatic bladder cancer. However, the data are limited to one trial only. Patients unable to tolerate cisplatin may benefit from gemcitabine plus carboplatin.

Abstract
Since the advent of cisplatin-based chemotherapy, cytotoxic combination chemotherapy remains the mainstay of treatment for locally advanced and metastatic urothelial malignancies. The current paradigm of combining novel agents with cytotoxic chemotherapy without any understanding of the underlying biology of urothelial cancer has limited the impact of developing novel agents for this disease. Current research investigating the biology of bladder cancer, including the role of p53, EMT, EGFR-related pathways, and anti-angiogenic pathways, may potentially impact the future development of novel agents targeting urothelial malignancies. Additionally, the use of novel gene therapy to mediate enhanced interferon expression in the bladder using adenoviral vectors, and enhancing tumor recognition strategies using the immune system with vaccines and anti-CTLA4 antibodies, are of interest. It is hoped that through these efforts we may soon move beyond the traditional cytotoxic chemotherapy paradigm, developing combinations that are more active and less toxic for all patients with urothelial cancer.

Abstract
Cancer of the urinary bladder is the fifth most prevalent solid tumour in the US. Urothelial carcinoma is the most common form of bladder cancer, accounting for about 90% of cases. About 25% of patients with bladder cancer have advanced disease (muscle-invasive or metastatic disease) at presentation and are candidates for systemic chemotherapy. Urothelial carcinoma is a chemo-sensitive disease, with a high overall and complete response rate to combination chemotherapy. In the setting of muscle-invasive urothelial carcinoma, use of neoadjuvant chemotherapy is associated with overall survival benefit. The role of adjuvant chemotherapy in this setting is yet to be validated. In the setting of metastatic disease, use of cisplatin-based regimens improves survival. However, despite initial high response rates, the responses are typically not durable leading to recurrence and death in the vast majority of these patients. Currently, there is no standard second-line therapy for patients in whom first-line chemotherapy for metastatic disease has failed. Many newer chemotherapeutic agents have shown modest activity in urothelial carcinoma. Improved understanding of molecular biology and pathogenesis of urothelial carcinoma has opened avenues for the use of molecularly targeted therapies, several of which are being tested in clinical trials. Currently, several novel drugs seem particularly promising including inhibitors of the epidermal growth factor receptor pathway, such as cetuximab, and inhibitors of tumour angiogenesis, such as bevacizumab and sunitinib. Development of reliable molecular predictive markers is expected to improve treatment decisions, therapy development and outcomes in urothelial carcinoma. Funding of and participation in clinical trials are key to advancing the care of urothelial cancer patients. Current and emerging strategies in the medical management of urothelial carcinoma are reviewed.

Abstract
BACKGROUND Recent publications suggest that a subgroup of patients can benefit from surgical removal of transitional cell carcinoma (TCC) metastases in addition to systemic chemotherapy. We report the combined experience and outcome of patients undergoing resection of TCC metastases at 15 uro-oncologic centers in Germany. MATERIALS AND METHODS Forty-four patients with distant metastatic TCC of the bladder or upper urinary tract underwent resection of all detectable metastases in 15 different German uro-oncological centers between 1991 and 2008 in an attempt to be rendered free of disease. RESULTS The resected metastatic sites consisted of retroperitoneal lymph nodes (56.8%), distant lymph nodes (11.3%), lung (18.2%), bone (4.5%), adrenal gland (2.3%), brain (2.3%), small intestine (2.3%), and skin (2.3%). The treatment sequence included systemic chemotherapy in 35/44 (79.5%) patients before and/or after surgery. Median survival times from initial diagnosis of metastatic TCC and subsequent resection were as follows: overall survival, 35 and 27 months, respectively; cancer-specific survival, 38 and 34 months, respectively; and progression-free survival, 19 and 15 months, respectively. Overall 5-year survival from metastasectomy for the entire cohort was 28%. Seventeen patients were still alive without progression at a median follow-up time of 8 months. Seven patients without disease progression survived for more than 2 years and remain free from tumor progression at a median of 63 months. CONCLUSION The results in this selected cohort confirm that long-term cancer control and possibly cure can be achieved in a subgroup of patients following surgical removal of TCC metastases. However, prospective data to identify patients most likely to benefit from this aggressive therapeutic approach are lacking. Therefore, metastasectomy in patients with disseminated TCC remains investigational and should be offered only to those with limited disease as a combined-modality approach with systemic chemotherapy.

Abstract
M-VAC (cisplatin, methotrexate, adriamycin, vinblastine) combination chemotherapy has been for long time the standard of care in fit patient with advanced urothelial tumors. Gemcitabine/cisplatin with similar results and an improved toxicity profile has proved to be a new standard alternative. Whether or not we can improve survival with newer triplet regimens will depend upon the results of ongoing phase III trials. In addition to the new active drug combinations and targeted therapies, new approaches are emerging for treatment. Chemotherapy optimization using molecular markers predicting chemosensitivity are being applied. There is an obvious need to incorporate in clinical trials a systematic translational approach to explain both our successes and our failures.

PURPOSE OF REVIEW Metastatic or unresectable urothelial cancer of the urinary bladder has traditionally been treated with systemic chemotherapy, which is most often platinum-based. The long-term survival data and the associated toxicities from this form of therapy have spurred continuing interest in finding novel treatment options for this malignancy. RECENT FINDINGS Recently, trials of new chemotherapy combinations, many incorporating platinum analogs or deleting platinum entirely, have been reported. None has yet been shown to be superior to cisplatin-based regimens. In addition, recent advances in imaging and laboratory technologies have provided new avenues to understand urothelial cancer behavior and prognosis. These advances provide optimism for improvements in the diagnosis, staging, and ultimately, selection of therapy for patients with urothelial cancer. SUMMARY This review will summarize recent developments (circa 2004) in the diagnosis and management of advanced bladder cancer.

Abstract
In anaesthetic practice we deal with cancer patients who are scheduled for operations on tumours or other manifestations of malignant disease. Those patients are often debilitated and have significant weight loss accompanied with hypoproteinaemia, anaemia and coagulation disorders. Oncological patients usually present to the anaesthetist before tumour disease surgery, but they are also candidates for elective operations (e.g. hernia repair) and urgent/emergency surgery (e.g. trauma, fractures and ileus). Chemotherapeutic agents given to these patients are potentially noxious, can affect the conduct of anaesthesia and, furthermore, may aggravate the patient's condition. In this review the most commonly used cytostatic drug regimens and their common side-effects are listed. Some preclinical studies on anaesthetic and cytostatic drug metabolism and interactions are emphasized, as well as clinically relevant perioperative alterations that may affect anaesthetic management in cancer patients. An anaesthetist may have to modify a routine anaesthetic regimen in cancer patients especially if anticancer chemotherapeutics were given. Clinically silent toxic drug effects may become apparent during operation, trauma or in the early postoperative course in such patients. Altered reactions to commonly used anaesthetics in patients receiving chemotherapeutics and an impaired stress reaction may occur in such patients. Special attention must be drawn to protection against opportunistic infections.

Abstract
Bladder cancer is the second most common genitourinary tumour and is a significant cause of morbidity and mortality. Trials of neoadjuvant and adjuvant chemotherapy have failed to show a survival advantage, although these studies generally had suboptimum design and an insufficient number of patients. Despite the introduction of newer agents, the median survival for metastatic disease is about 1 year; however, improvements in quality of life have been achieved. Platinum drugs should be included in studies of combination chemotherapy regimens wherever possible. There have been various studies exploring the role of taxanes, gemcitabine, ifosfamide, and platinum in double and triple combinations in different schedules to maximise dose intensity and improve effectiveness but large phase III trials are needed. The current tumour, node, and metastasis staging system is insufficient to predict outcome in patients with bladder cancer irrespective of the treatment they received. Evaluation of molecular prognostic markers should be incorporated into phase II and III trials to define their roles in clinical outcome. Future studies should stratify patients according to the number of risk factors they have to avoid imbalance in treatment groups and patients should be carefully selected.
