Abstract
Background Platinum-based chemotherapy is the standard treatment for advanced urothelial cancer (UC) and is generally used in the first-line setting. However, the optimal salvage treatment for previously treated UC patients is unclear. We conducted a systematic review of published clinical trials of single agent versus combined chemotherapy as salvage treatment in previously treated UC patients. Methods Trials published between 1994 and 2015 were identified by an electronic search of public databases (MEDLINE, EMBASE, Cochrane library). All relevant studies were independently identified by two authors for inclusion. Demographic data, treatment regimens, objective response rate (ORR), disease control rate (DCR), median progression-free and overall survival (PFS, OS), and grade 3/4 toxicities were extracted and analyzed using Comprehensive Meta Analysis software (Version 2.0). Results Fifty cohorts with 1,685 patients were included for analysis: 814 patients were treated with single agent chemotherapy and 871 with combined chemotherapy. Pooled OS was significantly higher at 1 year for combined chemotherapy than for single agent (relative risk [RR] 1.52; 95% CI: 1.01–2.37; P=0.03) but not for 2-year OS (RR 1.31; 95% CI: 0.92–1.85; P=0.064). Additionally, combined chemotherapy significantly improved ORR (RR 2.25; 95% CI: 1.60–3.18; P<0.001) and DCR (RR 1.12; 95% CI: 1.01–1.25, P=0.033) compared to single agent for advanced UC patients. As for grade 3 and 4 toxicities, more frequencies of leukopenia and thrombocytopenia were observed in the combined chemotherapy than in single agent group, while equivalent frequencies of anemia, nausea, vomiting, and diarrhea were found between the two groups. Conclusion In comparison with single agent alone, combined chemotherapy as salvage treatment for advanced UC patients significantly improved ORR, DCR, and 1-year OS, but not 2-year OS. Our findings support the need to compare combined chemotherapy with single agent alone in the salvage setting in large prospective trials due to its potential survival benefit in advanced UC patients.

Abstract
Patients with relapsed or refractory urothelial carcinoma (UC) face a poor prognosis and a dearth of available treatment options that improve their survival. End-organ function and performance status play a vital role in the choice of second-line therapies. Evidence supporting the use of cytotoxic chemotherapy, as single agents or in combination, arises from small phase 2 studies with modest responses. With the evolution of genomic testing in UC, several pathways amenable to available targeted therapies have emerged. Encouraging patient participation in clinical trials is critical to improve patient outcomes and to advance the current modest treatment armamentarium.

Abstract
AIMS To assess the efficacy and toxicity of methotrexate-paclitaxel-epirubicin-carboplatin combination as second-line chemotherapy in patients with metastatic transitional cell carcinoma (TCC) of the bladder pretreated with cisplatin-gemcitabine. METHODS In this prospective phase II study, patients with metastatic TCC of the bladder pretreated with first-line cisplatin-gemcitabine received on progression paclitaxel 175 mg/m(2) i.v. and carboplatin (area under curve of 5) on day 1, and methotrexate 40 mg/m(2) and epirubicin 40 mg/m(2) on day 15. The whole course was repeated every 28 days. The end-points included clinical tumor response, treatment toxicity, quality of life and survival. RESULTS A total of 40, predominantly male, patients were enrolled (median age 62 years [range 46-69]). Efficacy and survival were assessed in 38 patients only, as two patients refused treatment after the first cycle. Grade 3 neutropenia was the commonest acute severe toxicity (12/40 patients; 30%). The overall response rate was 39% (15/38 patients). The median follow up was 14 months (range 3-45). The median progression-free and overall survival were 12 and 12.5 months, respectively. The 1-year progression-free and overall survival were 24 and 35%, respectively. CONCLUSION Methotrexate-paclitaxel-epirubicin-carboplatin combination as second-line chemotherapy in patients with metastatic TCC of the bladder results in a modest response rate with acceptable toxicity.

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
Accounting for 14,000 deaths in the USA last year, research informs us that advanced bladder cancer is a lethal disease with a median survival that has remained a little over 1 year for the past two decades. For the majority of patients with metastatic disease, chemotherapy with cisplatin-based combinations is the standard first-line treatment. Although initial response rates are high, disease progression is common, creating a growing number of patients in need of effective second-line chemotherapy. For this population, no standard of care currently exists. Salvage chemotherapy is associated with low response rates and studies exploring potential clinical benefit over supportive care alone are limited to nonrandomized Phase II trials. Vinflunine, a novel anti-mitotic drug from the Vinca alkaloid class, is the first and only agent that has been compared with supportive care in the second-line setting. In Europe, vinflunine is approved as a treatment option for patients with advanced urothelial cancer who have failed a prior platinum-containing regimen. To date, in the USA, there is no FDA-approved second-line chemotherapy for patients with metastatic bladder cancer and treatment continues to emphasize patient enrollment into a clinical trial.

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
Vinflunine (VFL) is a third-generation bifluorinated semi-synthetic vinca alkaloid obtained by superacidic chemistry from its parent compound, vinorelbine. As with the other vinca alkaloids, the main antineoplastic effects of VFL arise from its interaction with tubulin, the major component of microtubules in mitotic spindles. In contrast to other vinca alkaloids, VFL shows some distinctive properties in terms of tubulin binding, possibly explaining its superior antitumor activity in vitro and in vivo compared with vinorelbine as well as its excellent safety profile. In transitional cell carcinoma (TCC), two single-agent phase II trials were performed testing VFL in platinum-pretreated patients, showing moderate response rates and promising disease control rates. Therefore, the first phase III trial in modern times for second-line TCC of the urothelium was designed in order to further investigate the activity of VFL. First results were presented at the 2008 ASCO conference. VFL appears to be a possible treatment option for patients with TCC progressing after first-line platinum-containing chemotherapy.

Abstract
OBJECTIVE Weekly administration of paclitaxel plus carboplatin is hypothesized to be an effective second-line treatment for advanced transitional cell cancer after failure of platinum-based regimen. In this phase 2 trial, we tested this hypothesis. PATIENTS AND METHODS Patients with advanced transitional cell cancer who showed evidence of progressive or recurrent disease after methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) therapy were eligible for this study. Weekly paclitaxel (80mg/m(2)) and carboplatin (AUC 2) were administered on days 1, 8, 15, 22, 29, and 36; the cycle was repeated every 7 wk until disease progression or intolerable toxicity (maximum 18 doses). RESULTS Thirty-five patients entered this study. Among the 31 patients who were assessable, 10 had an objective response (overall response rate: 32.3%, 95% confidence interval, 15.8-48.7%). The median progression-free survival (PFS) and median survival times were 3.7 and 7.9 mo, respectively. Among the 22 patients who received prior MVAC therapy for metastatic disease, 36% had an objective response; their median PFS and median survival times were 4.3 and 7.9 mo, respectively; neither survival time significantly differed from the survival time of those who received prior MVAC as adjuvant setting. Toxicities were mild except one toxic death due to neutropenic sepsis. CONCLUSIONS Weekly paclitaxel plus carboplatin was a manageable, active second-line treatment for advanced transitional cell cancer after failure of platinum-based therapy.

Abstract
BACKGROUND Based on evidence of activity in epithelial tumors in preclinical and Phase I studies, its novel mechanism of action, and its tolerability we undertook a study of bortezomib [PS-341], a reversible proteasome inhibitor, for patients with advanced or metastatic urothelial cancer. PATIENTS AND METHODS Patients with advanced or metastatic unresectable urothelial carcinoma were enrolled onto this multicenter, phase II trial. Patients with measurable disease were treated with bortezomib 1.3 mg/m2/day (twice weekly for 2 weeks out of 3) by intravenous infusion on days 1, 4, 8, and 11 every 21 days. A two stage phase II design was used. RESULTS Twenty-one patients were enrolled and twenty were eligible and received treatment. Eighty-five percent of patients had previous chemotherapy regimens. No objective responses were observed, median time-to-progression was 8.1 weeks (95% confidence interval [CI] 6.4 to 9), and median overall survival is estimated to be 15 weeks (95% CI 3.6 - NA). A total of 15 patients experienced a grade 3-4 adverse event. The most common were alkaline phosphatase (20% patients), lymphopenia (20% patients), myalgia (15% patients), dyspnea (15% patients) and thrombosis/embolism (15% patients). CONCLUSION Single-agent bortezomib is an ineffective treatment for progressive-cisplatin-refractory urothelial carcinoma and should not be considered for future clinical trials in this population of patients.

Abstract
Purpose To assess the antitumor activity and toxicity of pemetrexed as second-line chemotherapy in patients with locally advanced or metastatic transitional cell carcinoma (TCC) of the urothelium. Patients and Methods Eligible patients had a performance status of 0 or 1, adequate organ function, previous treatment with one prior chemotherapy regimen for locally advanced or metastatic TCC of the urothelium or relapsed within 1 year of adjuvant or neoadjuvant treatment. Patients received pemetrexed 500 mg/m2 intravenously on day 1 every 21 days, with vitamin B12, folic acid, and dexamethasone prophylaxis. Results Forty-seven patients were enrolled and included in the intent-to-treat efficacy analysis. Responses: 3 (6.4%) complete responses and 10 (21.3%) partial responses produced an overall response rate of 27.7%. Ten patients (21.3%) had stable disease and 22 patients (46.8%) progressed. The median time to progressive disease was 2.9 months (95% CI, 1.7 months to 4.6 months) and median overall survival was 9.6 months (95% CI, 5.1 months to 14.6 months). Median duration of response was 5.0 months (95% CI, 3.9 months to 13.8 months). Of the 47 patients assessable for safety, grade 3 or 4 hematologic events were thrombocytopenia (8.5%; 0.0%), neutropenia (4.3%; 4.3%) and anemia (2.1%; 2.1%), respectively. Nonlaboratory toxicities included grade 4 stomatitis/pharyngitis, sepsis syndrome (one patient each), and grade 3 fatigue (three patients) and diarrhea (two patients). Conclusion Single-agent pemetrexed is safe and active as second-line treatment of patients with advanced TCC of the urothelium. Additional evaluation in the first- or second-line setting in TCC of the urothelium is warranted.

Abstract
In this study, the feasibility and activity of combined chemotherapy of the farnesyl transferase inhibitor SCH66336 and gemcitabine was evaluated. This therapy was used as second-line treatment in patients with advanced urothelial tract cancer and the influence of SCH66336 exposure on the pharmacokinetics of gemcitabine was also determined. Patients who had received one previous chemotherapy regime for advanced urothelial cancer were treated with a combination of SCH66336 (150 mg in the morning and 100 mg in the evening) and Gemcitabine (1000 mg/m2 on day 1, 8 and 15 per 28-day cycle). Dosages of gemcitabine and its metabolite dFdU were performed on day one of cycle 1 before exposure to SCH66336 and day one of cycle 2. A total of 152 cycles were administered in 33 patients (median 3, range: 1-15). No patients had severe hematological toxicity, defined as Grade 4 thrombocytopenia or febrile neutropenia. Nine partial responses and one complete response were achieved in 31 assessable patients and corresponded to an overall response rate of 32.3% [95% CI:17%-51%]. There was no influence of exposure to SCH66336 on the level of gemcitabine or dFdU in 11 assessable patients. In conclusion, a combination of SCH66336 and gemcitabine is feasible in terms of toxicity and active as second-line treatment in patients with advanced urothelial tract cancer. SCH66336 had no effect on the pharmacokinetics of gemcitabine. Randomised trials should be undertaken to clarify the role of SCH66336 in combination with gemcitabine in cancer treatment.

Abstract
Cisplatin based combination chemotherapy remains the mainstay for treatment of advanced urothelial cancer. The combination of 5-fluorouracil and interferon has been found to be effective second line treatment of advanced urothelial cancer. Hence, we tested the combination of cisplatin, 5-fluorouracil and interferon as first line therapy in advanced urothelial cancer. Eligible patients had to have no prior chemotherapy or interferon. Treatment consisted of cisplatin 80 mg/m(2) on day one, followed by 5-fluorouracil 750 mg/m(2) as a daily infusion for 5 days and interferon alpha 2 B 5 MU/m(2) subcutaneously daily on day 1-5 of 5-fluorouracil infusion. Cycles repeated every 21 days. Eighteen patients, of which sixteen were males were enrolled. Median age was 60 years. All patients had transitional-cell carcinoma. The median number of cycles given was 4. Thirteen patients were evaluable for response. Two patients achieved CR and 3 PR for an overall response rate of 28% (95% confidence interval 7% to 49%). Median response duration was 8.3 months. Median survival was 5.5 months. Four patients died secondary to chemotherapy toxicities. Those were GI perforation in one, bronchopneumonia in one, acute renal failure in one and one patient died at home 3 weeks following the third cycle. The above regimen demonstrates excessive toxicity and moderate activity. It cannot be recommended in its present format. Novel anti-cancer agents need to explored.

Abstract
BACKGROUND An every-2-week regimen of gemcitabine and paclitaxel was adapted for patients with advanced transitional cell carcinoma (TCC) who had received prior cisplatin-based chemotherapy. METHODS Forty-one patients with advanced or metastatic TCC who had received prior cisplatin-based systemic chemotherapy were treated with an outpatient regimen of gemcitabine 2500-3000 mg/m(2) and paclitaxel 150 mg/m(2) every 2 weeks. RESULTS Forty of 41 patients had measurable disease. Response was observed in 24 patients (60%; 95% confidence interval [CI], 45-75%). Eleven (28%) achieved complete response, and 13 (33%) obtained partial response. Twenty of 25 patients (80%; 95% CI, 64-96%) who had been previously treated in the neoadjuvant or adjuvant setting responded versus 4 of 15 (27%; 95% CI, 5-49%) in patients who received prior methotrexate, vinblastine, doxorubicin, cisplatin (M-VAC) for metastatic disease. The median duration of survival for patients given gemcitabine and paclitaxel after failing neoadjuvant or adjuvant M-VAC was 12 months (range, 2-43+), as compared with only 8 months (range, 2-28) for patients who had been treated after failure of prior therapy for metastatic disease. For all patients, the median duration of response was 6.4 months (range, 2-43.3+ months), and the median survival was 14.4 months (range, 2-43+). Thirteen patients (32%) developed World Health Organization Grade 3-4 neutropenia, with febrile neutropenia in 3 (7%) patients. Granulocyte colony-stimulating factor was given to 10 (24%) patients. There was no Grade 3-4 anemia or thrombocytopenia. CONCLUSIONS The combination of gemcitabine and taxol in previously treated patients with recurrent TCC is highly effective and produces objective durable responses. This every-2-week schedule is a well tolerated outpatient regimen with minimal toxicity.

Abstract
Cisplatin-based combination chemotherapy such as methotrexate, vinblastine, adriamycin and cisplatin produces durable improvements in survival in only a minority of patients. Therefore, other therapeutic options and strategies are clearly needed. Strategies include increasing the dose of chemotherapy, modifying the sequencing of chemotherapy, and new therapeutic agents. This paper reviews recent work on high-dose chemotherapy, currently available chemotherapeutic agents and combinations, with an emphasis on gemcitabine and the taxanes. New strategies such as monoclonal antibody therapy and molecular targeted small molecule therapy are becoming a reality in the treatment of many diseases. The rationale for using epidermal growth factor receptor targeted therapies is also reviewed.
