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.

Abstract
PURPOSE To compare long-term survival in patients with locally advanced and metastatic transitional cell carcinoma (TCC) of the urothelium treated with gemcitabine plus cisplatin (GC) or methotrexate/vinblastine/doxorubicin/cisplatin (MVAC). PATIENTS AND METHODS Efficacy data from a large randomized phase III study of GC versus MVAC were updated. Time-to-event analyses were performed on the observed distributions of overall survival time and progression-free survival. RESULTS Four hundred and five patients were randomized, 203 to the GC arm and 202 to the MVAC arm. At the time of this analysis, 347 patients have died (GC 176, MVAC 171). Overall survival was similar in both arms (HR 1.09; 95% confidence interval [CI] 0.88-1.34, P = 0.66) with a median survival of 14.0 months (95% CI 12.3-15.5 months) in the GC, and 15.2 months (95% CI 13.2-17.3 months) in the MVAC arm. The median progression-free survival was 7.7 months with GC (95% CI 6.8-8.8) and 8.3 months with MVAC (95% CI 7.3-9.7) with a HR of 1.09 (95% CI 0.89-1.34). Significant prognostic factors favoring overall survival included performance status (>70), TNM staging (M0 vs. M1), low/normal alkaline phosphatase expression, number of sites of disease <3, and the absence of visceral metastasis. By adjusting for these prognostic factors, the HR was 0.99 for overall survival and 1.01 for progression-free survival. CONCLUSIONS Long-term overall and progression-free survival following treatment with GC or MVAC are similar. These results strengthen the role of GC as a standard of care in patients with locally advanced and metastatic transitional-cell carcinoma (TCC).

Abstract
Urothelial cancer is a common malignancy. The management of patients with recurrent disease after cystectomy or initially metastatic or unresectable disease represents a therapeutic challenge. Systemic chemotherapy prolongs survival but long-term survival remains infrequent. During recent years there has been improvement due to the use of novel chemotherapeutic agents, mainly gemcitabine and the taxanes. The long-considered-standard MVAC has been challenged by combinations showing more favourable toxicity profiles and equal (gemcitabine-cisplatin) or even improved (dose-dense, G-CSF-supported MVAC) efficacy. Specific interest has also been generated in specific groups of patients (elderly patients, patients with renal function impairment or comorbidities), who are not fit for the standard cisplatin-based chemotherapy but can derive significant benefit from carboplatin- or taxane-based treatment. Retrospective analyses have enabled the identification of groups of patients with different prognoses, who possibly require different therapeutic approaches. Modern chemotherapy offers a chance of long-term survival in patients without visceral metastases, possibly in combination with definitive local treatment. Finally, the progress of targeted therapies in other neoplasms seems to be reflected in advanced bladder cancer by recent studies indicating that biological agents can be combined with modern chemotherapy. The true role of such therapies is currently being evaluated.

Abstract
BACKGROUND Bladder cancer is the fifth most common cancer among men and the seventh among women. At diagnosis, at least 25% of bladder cancer tumors are locally or systemically advanced. Systemic chemotherapy is the only current modality for advanced or metastatic transitional cell carcinoma of the bladder. Recently, a phase III randomized study has demonstrated that the regimen with gemcitabine (GMC) and cisplatin (CDDP) had a survival advantage similar to the standard M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin), with a better safety profile. AIM It was the aim of this study to evaluate the tumor response rate, the median time to progression, the median survival and toxicity in a 21-day schedule with GMC and CDDP in patients with advanced/metastatic bladder cancer. PATIENTS AND METHODS From September 1998 to December 2000, 27 patients with advanced/metastatic transitional cell carcinoma were enrolled. All patients received 1,200 mg/m(2) GMC administered as a 30-min intravenous infusion on days 1 and 8, and 75 mg/m(2) CDDP as a 1-hour infusion on day 2. Cycles were repeated every 21 days. The patients had a median age of 59.8 years (range 39-75) and an Eastern Cooperative Oncology Group performance status of 0-2. RESULTS Twenty-five patients were valuable for toxic effects, length of survival and tumor response. The statistical analysis was performed in May 2004. Mean and median follow-up were 20.23 and 13.2 months (range 2-68), respectively. The overall remission rate (complete response + partial response) was 48% (95% CI 28.4-67.6%). The median time to progression was 9 months (range 2-56). The median duration of survival for all patients was 13.2 months (range 2-68+), with 1-year and 23-month survival rates of 60 and 20%, respectively. There was no grade 4 toxicity or treatment-related death. Grade 3 anemia was observed in 4 patients (16%) and grade 3 thrombocytopenia occurred in 6 patients (24%). No grade 3-4 nausea/vomiting or neutropenia was observed. CONCLUSION GMC and CDDP is an active schedule with a good safety profile in a 21-day regimen. It may be a valid alternative to the standard 28-day regimen due to its high tumor response and survival with a low incidence of toxicity, especially in pretreated and metastatic patients.

Abstract
This paper reviews the current status of systemic chemotherapy in the management of advanced and metastatic urothelial cancer. The activity of a number of single agents and combination drug regimens is discussed, and the small number of randomised-controlled studies available is also considered. Prognostic factors for response and survival, particularly long-term survival after systemic chemotherapy, are also reviewed. Special consideration is given to the role of systemic chemotherapy as a precursor to surgery (or radiotherapy) in locally advanced disease that is initially considered incurable. Therapeutic options for patients unable to tolerate cisplatin owing to renal impairment or other comorbidities are explored. Future directions are explored, including the role of molecular phenotyping in providing prognostic information, indicators of the likely success of conventional therapeutic measures and the development of specific targeted therapies.

Abstract
PURPOSE To compare long-term survival in patients with locally advanced or metastatic transitional cell carcinoma (TCC) of the urothelium treated with gemcitabine/cisplatin (GC) or methotrexate/vinblastine/doxorubicin/cisplatin (MVAC). PATIENTS AND METHODS Efficacy data from a large randomized phase III study of GC versus MVAC were updated. Time-to-event analyses were performed on the observed distributions of overall and progression-free survival. RESULTS A total of 405 patients were randomly assigned: 203 to the GC arm and 202 to the MVAC arm. At the time of analysis, 347 patients had died (GC arm, 176 patients; MVAC arm, 171 patients). Overall survival was similar in both arms (hazard ratio [HR], 1.09; 95% CI, 0.88 to 1.34; P = .66) with a median survival of 14.0 months for GC and 15.2 months for MVAC. The 5-year overall survival rates were 13.0% and 15.3%, respectively (P = .53). The median progression-free survival was 7.7 months for GC and 8.3 months for MVAC, with an HR of 1.09. The 5-year progression-free survival rates were 9.8% and 11.3%, respectively (P = .63). Significant prognostic factors favoring overall survival included performance score (> 70), TNM staging (M0 v M1), low/normal alkaline phosphatase level, number of disease sites (<or= three), and the absence of visceral metastases. By adjusting for these prognostic factors, the HR was 0.99 for overall survival and 1.01 for progression-free survival. The 5-year overall survival rates for patients with and without visceral metastases were 6.8% and 20.9%, respectively. CONCLUSION Long-term overall and progression-free survival after treatment with GC or MVAC are similar. These results strengthen the role of GC as a standard of care in patients with locally advanced or metastatic TCC.

Abstract
OBJECTIVES This study aimed to evaluate the efficacy and toxicity of gemcitabine in combination with cisplatin as neoadjuvant therapy in patients with cervical carcinoma stage IB2. PATIENTS AND METHODS Chemotherapy-naive patients with histologic diagnosis of squamous cell cervical carcinoma staged as IB2 were treated with 2 cycles of cisplatin (70 mg/m(2) on day 1) and gemcitabine (1000 mg/m(2) on days 1 and 8), given every 21 days. After chemotherapy, patients underwent radical hysterectomy and pelvic lymphadenectomy. Patients judged to have a non-resectable disease were treated with standard pelvic radiation. RESULTS Between September 2000 to March 2004, 28 patients were enrolled in the study, of which 27 were evaluable for efficacy and toxicity. The mean age was 39 years (30-55). The overall clinical response rate was 88.9% (24/27), with complete response (CR) in 9/27 patients (33.3%) and partial response in 15/27 patients (55.5%). Three patients (11.1%) did not respond and nobody progressed. A pathological CR was noted in 2 of 24 patients who underwent radical surgery. The 3 non-responding patients were subsequently treated with radiation and achieved CR. Grades 3 or 4 neutropenia, anemia, or thrombocytopenia was observed in 18.5%, 7.4%, and 3.7% patients respectively. Non-hematological toxicity was mild except grade 3 nausea/vomiting in 18.5% patients. At median follow-up time of 36.7 months (range 7-51 months), the 3-year survival was 88.9%. CONCLUSION Neoadjuvant treatment with gemcitabine/cisplatin combination for patients with cervical cancer (stage IB2) appears encouraging, with manageable and acceptable toxicity profile.

Abstract
The purpose of the study was to investigate the toxicity and efficacy of the combination of gemcitabine and docetaxel in untreated advanced urothelial carcinoma. Patients with previously untreated, locally advanced/recurrent or metastatic urothelial carcinoma stage-IV disease were eligible. Patients with Performance status: PS ECOG >3 or age >75 years or creatinine clearance <50 ml min(-1) were excluded. Study treatment consisted of docetaxel 75 mg m(-2) (day 8) and gemcitabine 1000 mg m(-2) (days 1+8), every 21 days for a total of six to nine cycles. A total of 31 patients with urothelial bladder cancer, 25 men and six women, aged 42-74 (median 64) years were enrolled. The majority of patients had a good PS (51.6%; PS 0). In all, 15 (48.3%) patients had locally advanced or recurrent disease only and 16 (54.8%) presented with distant metastatic spread, with multiple site involvement in 22.5%. Toxicity was primarily haematologic, and the most frequent grade 3-4 toxicities were anaemia 11 (6.7%) thrombocytopenia eight (4.9%), and neutropenia 45 (27.6%), with 10 (6.1%) episodes of febrile neutropenia. No toxic deaths occurred. A number of patients had some cardiovascular morbidity (38.7%). Nonhaematological toxicities except alopecia (29 patients) were mild. Overall response rate was 51.6%, including four complete responses (12.9%) and 12 partial responses (38.7%), while a further five patients had disease stabilisation (s.d. 16.1%). The median time to progression was 8 months (95% CI 5.1-9.2 months) and the median overall survival was 15 months (95% CI 11.2-18.5 months), with 1-year survival rate of 60%. In conclusion, this schedule of gemcitabine and docetaxel is very active and well tolerated as a first-line treatment for advanced/relapsing or metastatic urothelial carcinoma. Although its relative efficacy and tolerance as compared to classic MVAC should be assessed in a phase III setting, the favourable toxicity profile of this regimen may offer an interesting alternative, particularly in patients with compromised renal function or cardiovascular disease.

Abstract
The purpose of the study was to evaluate response and survival in patients with metastatic urothelial cancer treated with combination gemcitabine and paclitaxel administered on a biweekly schedule at doses of 3000 mg/m2 and 150 mg/m2, respectively. Patients with adequate organ function and performance status were accrued through 7 institutions, stratified by prior therapy status, and treated as noted. Response was evaluated by 1979 bi-dimensional World Health Organization (WHO) criteria. Of 55 eligible patients, 17 had a partial and 5 had a complete response rate for an overall response rate of 40% (27-54%). One complete response and one partial response were observed in the 6 previously treated patients. Overall median survival was 11.8 months (11.9 months in the chemonaive cohort). Grade 3 or 4 myelosuppression occurred in 56%, but only 4 serious infections were observed. We conclude that because of a lower than expected complete response rate, even when corrected for prognostic groupings, this regimen is not recommended for routine use in patients with metastatic urothelial cancer. Insufficient patients with poor renal function or prior therapy were accrued to reach conclusions regarding its utility in these subgroups.

Abstract
Many localised, superficial bladder cancers can be effectively controlled. However, disease which has spread to nodes outside the pelvis or to distant organs is generally incurable and systemic therapies, rather than surgery, are appropriate. Combination chemotherapy based around established cytotoxic drugs such as cisplatin has proven benefit in palliating symptoms and prolonging survival in responsive patients with advanced disease. Combination chemotherapies which include newer cytotoxic drugs such as gemcitabine provide the potential for equivalent efficacy with less toxicity than established regimens. Between the extremes of superficial and advanced disease, muscle-invasive bladder cancers have traditionally been treated, with curative intent, by radical surgery or radiotherapy. However, newly published data suggest, for the first time, genuine survival benefits from peri-operative chemotherapy. This article reviews the evidence for cisplatin-based chemotherapy in advanced disease, assesses the potential benefits of newer cytotoxic drugs, discusses the latest evidence pertaining to peri-operative chemotherapy in muscle-invasive disease, and looks forward to potential new biological agents in the systemic therapy of bladder cancer.

Abstract
PURPOSE Although the use of radical transurethral resection followed by concurrent radiochemotherapy leads to a similar survival rate to that achieved after cystectomy, the number of long-term survivors is low in both cases. An improvement may be obtained by adding a new drug, such as gemcitabine, which is active in bladder cancer and acts as a radiosensitizer. However, because gemcitabine may be very toxic when associated with radiotherapy, we designed this dose-finding study in an attempt to find the dose that can be safely added to radiotherapy and concurrent cisplatin in patients treated with transurethral resection for infiltrating bladder cancer. PATIENTS AND METHODS After undergoing macroscopically complete transurethral resections for transitional carcinoma of the bladder, patients staged pT2 or higher and without distant metastases concurrently received 54 Gy of fractionated radiotherapy over 6 weeks with cisplatin (100 mg/m(2) q.3 w), starting on Day 1 of radiotherapy. Concomitant gemcitabine was administered on Days 1, 8, and 15 q.3 w for 2 cycles at a dose of 200 mg/m(2), escalated to 500 mg/m(2), with a 100 mg/m(2) increase at each dose level. The maximum tolerated dose was defined as the dose of gemcitabine associated with dose-limiting toxic effects (febrile neutropenia, Grade 4 thrombocytopenia, Grade 3 or 4 enteric toxicity, or Grade 4 nonhematologic toxicity) in 33% of the patients treated at that dose level. Six to 8 weeks after completing the therapy, the patients underwent cystoscopic reevaluation with multiple biopsies of the initial tumor site. RESULTS Of our consecutive series of 16 patients, 5 received a gemcitabine dose of 200 mg/m(2)/week, 3 a dose of 300 mg/m(2)/week, 3 a dose of 400 mg/m(2)/week, and 5 a dose of 500 mg/m(2)/week for 6 weeks. No dose-limiting toxicity was observed at doses of up to 400 mg/m(2)/week. At the dose 500 mg/m(2)/week, 1 patient experienced an intestinal perforation that recovered after surgery, and another suddenly died after developing Grade 3 untreated diarrhea in the last treatment week. All of the 15 evaluable patients were microscopically disease free at the cystoscopic reevaluation; furthermore, the posttreatment computed tomography scans did not reveal any distant metastases. CONCLUSIONS After transurethral resection for the conservative treatment of infiltrating bladder cancer, gemcitabine doses of up to 400 mg/m(2)/week seem to be safe in combination with cisplatin and radiotherapy in organ-sparing management. On the basis of the promising results of this Phase I study, we are currently conducting a Phase II trial to verify the possible improvement in local control resulting from the addition of gemcitabine.

Abstract
A large multinational phase III trial performed during the late 1990s compared two systemic chemotherapy regimens gemcitabine plus cisplatin and methotrexate, vinblastine, doxorubicin, cisplatin (M-VAC) in more than 400 patients with advanced or metastatic urothelial cancer. This trial has been discussed to landmark the beginning of a new era following M-VAC polychemotherapy which has dominated treatment of advanced urothelial cancer throughout the previous decade. Despite the fact that gemcitabine/cisplatin combination therapy did not surpass M-VAC therapy in regard to patient survival as initially intended, this combination demonstrated a more favourable toxicity profile with improved tolerability and superior cost effectiveness, rendering this combination an attractive alternative to M-VAC. This review on the largest to date phase III trial for advanced or metastatic urothelial cancer will focus on issues of quality of life including indicators such as performance status and changes in body weight. Furthermore, data on medical resources utilization as accounted during systemic polychemotherapy and related toxic events will be reconsidered, particularly under the impression of decreasing health care resources worldwide.

Abstract
The median survival of patients with metastatic cancer of the urothelium who receive best supportive care only in 4-6 months. With the introduction of combination chemotherapy regimens including cisplatin and methotrexate for the management of metastatic urothelial cancer, median overall survival has doubled. Nevertheless, death due to cancer ultimately occurs in more than 80% of these patients, thus more effective therapy is required. The new available treatment modalities range from new combinations of conventional chemotherapeutic agents to combinations incorporating novel drugs like gemcitabine and the taxanes. These new combinations incorporate the new active agents in two, three or multiple drug combinations, administered either in one regimen or sequentially in various combinations and schedules intended to improve the outcome of bladder cancer patients. Ongoing phase III studies will help to define the role of these new combinations in the treatment of advanced bladder cancer. The improved understanding of the molecular biology of urothelial malignancies is helping to define the role of new prognostic indices that can direct the most appropriate choice of treatment for advanced disease. In addition, advances in the molecular biology of urothelial malignancies may allow identification of specific genetic lesions and biochemical pathways upon which future therapeutic approaches can be focused. The integration of newer biologic agents, probably to supplement rather than to supplant chemotherapeutic drugs, should be a primary direction of research with the objective to interfere with multiple aspects of bladder cancer progression.

Abstract
In the 1990s, the European Organization for Research and Treatment of Cancer Genito-Urinary (EORTC GU) Group focused on dose-intensity concepts of the methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) regimen for patents with bladder cancer. In a randomized trial in patients with advanced urothelial cell cancer, standard MVAC was compared with 2-weekly intensified MVAC plus granulocyte-colony stimulating factor (G-CSF) support. Although the dose-intensified therapy resulted in a higher overall and complete response rates, it did not result in a better median survival. In parallel, the Spanish Oncology Genitourinary Group (SOGUG), in collaboration with the EORTC GU Group, conducted Phase I and II trials to investigate the feasibility and efficacy of the incorporation of two new active agents, gemcitabine and paclitaxel, into two-drug or three-drug cisplatin-based or carboplatin-based regimens. The EORTC GU Group currently is conducting randomized studies of combined paclitaxel, cisplatin, and gemcitabine compared with combined gemcitabine plus cisplatin in patients with good performance status and good renal function and studies of combined gemcitabine plus carboplatin compared with combined carboplatin, methotrexate, and vinblastine in patients who are unsuited for cisplatin. In the 1990s, the EORTC coordinated a large Intergroup study of neoadjuvant cisplatin, methotrexate, and vinblastine chemotherapy versus no chemotherapy before definitive treatment. That study included 976 patients and was based on a design to detect at least a 10% absolute improvement in survival. The final results showed a 5.5% survival difference at 3 years in the chemotherapy arm. The EORTC GU Group currently is coordinating an Intergroup study that was designed to detect an improvement of 7% in absolute survival in the adjuvant setting. Cancer 2003;97(8 Suppl):2120-6.

Abstract
Of 405 patients with stage IV transitional cell carcinoma from an international multicenter phase III trial, 70 were randomized in Germany to receive either gemcitabine/cisplatin or standard MVAC systemic chemotherapy for locally advanced or metastatic urothelial cancer. Overall survival as the primary endpoint of the study was similar in both arms (median survival GC 15.4 months vs MVAC 16.1 months), as were tumor-specific survival and time to progressive disease. In the intent-to-treat analysis, the 5-year overall survival rate was 10% for patients randomized to GC and 18% randomized to MVAC. Tumor overall response rates (GC 54%, MVAC 53%) were similar. The toxic death rate was 0% in the GC arm and 3% (one patient) in the MVAC arm. Significantly more GC than MVAC patients experienced grade 3/4 anemia (GC 52%, MVAC 20%) with significantly more red blood cell transfusions in the GC arm.Significantly more GC than MVAC patients had grade 3/4 thrombocytopenia (GC 54%, MVAC 17%) without grade 3/4 hemorrhage or hematuria in either arm. More MVAC patients experienced grade 3/4 neutropenia (GC 56%, MVAC 61%, p=1.000), neutropenic or leukopenic fever (GC 0%, MVAC 10%, p=0.237), mucositis (GC 0%, MVAC 7%, p=0.495), and alopecia (GC 6%, MVAC 36%, p=0.004). GC represents a reasonable alternative for the palliative treatment of patients with locally advanced and metastatic transitional cell carcinoma. Sustained long-term survival was only found for patients with locally advanced cancer, lymphatic metastases, or solitary distant metastasis but not for visceral metastatic disease.

Abstract
Pancreatic cancer has one of the worst prognosis of any malignant disease. Systemic therapy is often administered because the disease is usually detected at advanced stages. Gemcitabine (Gemzar trade mark, Eli Lilly & Co.) has proven activity in the treatment of pancreatic cancer. Gemcitabine 1000 mg/m(2) was given on days 1, 8 and 15, every 4 weeks. A total of 100 chemonaive patients with locally advanced or metastatic pancreatic cancer were enrolled; 32 and 68% had stage III and IV disease, respectively. The average number of administered cycles was 3.5 (range: 1 - 12). The overall response rate was 13%, with 13 partial responders. The median time to progression was 13.5 weeks (range: 3 - 56; 95% CI = 12 - 14). The median survival was 32 weeks (range: 4 - 104; 95% CI = 27 - 36). Clinical benefit response was acheived for 26 patients (26%). Grade 3/4 haematological toxicities occurred infrequently (anaemia: 5%; neutropenia: 8% and thrombocytopenia: 3% of patients). Grade 3/4 non-haematological toxicities were not observed. There were no treatment-related deaths. Gemcitabine treatment of patients with locally advanced or metastatic pancreatic cancer is effective and well-tolerated.

Abstract
Patients with localised but muscle-invasive transitional-cell carcinoma (TCC) of the bladder are at high risk of relapse and death from metastatic disease after local treatment by cystectomy, radiation, or both. Despite improvements in treatment, patients with metastatic TCC have a median survival of about a year. TCC is quite sensitive to chemotherapy, and patients are able to tolerate newer regimens such as gemcitabine plus cisplatin better than older regimens such as methotrexate, vinblastine, doxorubicin, and cisplatin. However, the role of chemotherapy in the management of locally advanced muscle-invasive TCC remains uncertain. Most trials of neoadjuvant or adjuvant chemotherapy have shown no significant improvement in survival, but many of these studies had suboptimum design, evaluated chemotherapy that was less effective than regimens in current use, and had sample sizes that were too small for important changes in survival to be detected or ruled out. Recent trials show trends in the direction of improved survival when optimum chemotherapy is used. Large trials that recruit more than 1000 patients are required to assess the effectiveness of adjunctive chemotherapy, and a large intergroup trial is in progress. Other trials should address the role of molecular markers in selecting patients for chemotherapy. Whenever possible, chemotherapy for locally advanced muscle-invasive TCC should be given in the context of a well-designed clinical trial.

Abstract
BACKGROUND The objective of this study was to evaluate the efficacy and toxicity of gemcitabine plus epirubicin in previously untreated patients with advanced urothelial carcinoma who were not eligible for cisplatin-based regimens. METHODS Patients with advanced urothelial carcinoma and at least one of the following characteristics were eligible: impaired renal function (creatinine clearance < 60 mL per minute), an Eastern Cooperative Oncology Group performance status (PS) >or= 2, and age >or= 75 years. The treatment included epirubicin 70 mg/m(2) as an intravenous bolus on Day 1 and gemcitabine 1000 mg/m(2) over 30 minutes on Days 1 and 8 of a 21-day cycle. RESULTS Thirty-eight patients entered the study, and a total of 152 cycles were administered, with a median of 4 cycles per patient (range, 1-6 cycles per patient). The following Grade 3-4 hematologic toxicities were reported (percent of cycles): neutropenia, 22.4%; anemia, 11.2%; and thrombocytopenia, 6.5%. No cardiac, renal, or hepatic toxicities were observed. Dose intensities of epirubicin and gemcitabine were 19.6 mg/m(2) per week (84%) and 532.2 mg/m(2) per week (80%), respectively. There were 2 complete responses (5.3%), 13 partial responses (34.2%), 11 patients with stable disease (28.9%), and 12 patients with progressive disease (31.6%), for an overall response rate of 39.5% (95% confidence interval, 25.1-55.1). The median progression free survival (PFS) and overall survival (OS) rates were 4.8 months and 8.0 months, respectively. The 1-year survival rate was 38%, and the median PFS and OS were 6.4 months and 16.4 months, respectively, in patients with PS 0-1. Thirty patients were symptomatic: Seventeen patients (56.7%) achieved a complete response, and 5 patients (16.7%) achieved a partial symptomatic response. CONCLUSIONS At the doses given in this study, gemcitabine and epirubicin had a good tolerability profile with interesting activity in patients with advanced urothelial carcinoma who were not fit for cisplatin-based regimens.

Abstract
To evaluate the clinical value of the concurrent use of methotrexate administered immediately before paclitaxel, we investigated the efficacy and toxicity of this two-drug combination administered as palliative second line therapy in patients with advanced urothelial cancer. The design of the schedule and sequence used was based on our previous preclinical data from a comparative study on sequential combinations of paclitaxel and methotrexate in a human bladder cancer cell line. As a confirmation study, we further extended our analysis of in vitro synergism. Twenty patients with advanced transitional cell carcinoma of the urinary tract previously treated with platinum-based therapy, with adequate renal function and a performance status > or = 60 were considered eligible. They received therapy with methotrexate 30 mg/m2 administered as an intravenous bolus, followed immediately by paclitaxel 175 mg/m2 given as a 3-hr infusion, both on day 1 every 21 days. Therapy was given on a compassionate-use basis until either disease progression was documented or the patient became intolerant to therapy. In vitro data were further analyzed using the median-effect principle and the combination index method. Twenty patients with metastatic (16 patients) or locally advanced disease (four patients) received a median of three cycles of therapy. Of the 19 patients assessable for response, there were six partial responses and seven disease stabilizations with no complete responses. Median duration of response was 3 months (range, 2-7) and median survival was 5 months. Three patients developed grade 3-4 neutropenia, one patient had grade 3 anemia, four patients had grade 2-3 sensory neuropathy, and three patients had myalgias. Eighteen patients developed alopecia. Gastrointestinal toxicity was mild. One patient died after the first cycle due to pulmonary thrombo-embolism and could not be evaluated for response. The synergistic in vitro effect of the concurrent combination was confirmed in analyses performed under mutually exclusive and mutually nonexclusive criteria. In conclusion, the combination of methotrexate and paclitaxel at this dose and sequence is feasible and active as a palliative therapy in patients with advanced urothelial cancer previously treated with platinum-based therapies. This schedule merits further investigation in a phase-II trial.

Abstract
The median survival of patients with metastatic bladder cancer treated with methotrexate, vinblastine, adriamycin, and cisplatin chemotherapy is approximately 1 year and long-term survival occurs in a small proportion of patients. Recent efforts to improve the outcome of patients with metastatic transitional cell carcinoma have focused on the identification of new drugs with single agent activity and on their incorporation into platinum-based combination regimens. Paclitaxel, docetaxel, ifosfamide and gemcitabine are among the most active new agents. A large number of phase I/II trials have evaluated these agents in two- and three-drug combination regimens. The response proportion observed with these combinations varies considerably and median survival times range from 8 to 20 months. Because it is known that pretreatment prognostic features have an impact on individual patient outcome, the variation in reported survival in patients treated with chemotherapy may be a consequence of pretreatment patient characteristics. The role of surgery in metastatic bladder cancer is still controversial. After a significant response to chemotherapy, resection of residual resistant disease may be performed with intent to cure in highly selected patients. As obtainment of complete remission is a prerequisite for long-term survival, new therapeutic strategies, such as molecular targeted small molecule therapy and monoclonal antibodies, and new molecular markers predictive of response have the potential to be incorporated into the current treatment strategies, increasing the rate of cure.

Abstract
BACKGROUND New chemotherapeutic agents, including paclitaxel and gemcitabine, are active in advanced bladder carcinoma, and combination regimens with these agents have shown promising results. Unlike conventional chemotherapy regimens, such as methotrexate, vinblastine, doxorubicin, and cisplatin, there are no data available on key predictive factors for response and survival with these novel agents. Since this information is needed for selection of patients for these new combinations and for stratification purposes in ongoing randomized trials, the authors aimed to study the predictive factors for response and survival to the current regimen containing cisplatin, paclitaxel, and gemcitabine. METHODS The authors studied 56 patients with advanced urothelial tumors treated on a Phase I/II trial of paclitaxel, cisplatin, and gemcitabine (TCG) to identify pretreatment characteristics that were prognostic for survival using this novel combination. The pretreatment characteristics analyzed were age, gender, Eastern Cooperative Oncology Group performance status, histopathology (pure transitional versus other), visceral (liver, lung, or bone) metastasis, number of sites of disease, lactate dehydrogenase, and hemoglobin. RESULTS The factors that were associated with a worse survival in univariate analysis were performance status > 0, presence of visceral metastasis, and more than one site of malignant disease. In a multivariate model, performance status (P = 0.044) and visceral disease (P = 0.008) showed independent statistical significance for decreased survival. Patients were then grouped based on these two independent prognostic factors. Median survival times in the groups of patients with zero, one, or two of these risk factors were 32.8 months, 17 months, and 9.6 months, respectively (P = 0.0005). CONCLUSIONS A pretreatment performance status > 0 and the presence of visceral metastasis have a profound impact on survival when using the TCG regimen. These two variables will be used to stratify patients in the upcoming Phase III randomized trial comparing this TGC regimen with a gemcitabine/cisplatin regimen in advanced urothelial tumors.

Abstract
PURPOSE To assess long-term survival and prognostic indicators of survival in patients with advanced urothelial cancer treated with gemcitabine and cisplatin. MATERIALS AND METHODS Survival data from three previously published phase II trials of gemcitabine/cisplatin were updated. Baseline hemoglobin, performance status, and presence of visceral metastases, which are known prognostic factors with other regimens, were examined. Survival curves were constructed by the Kaplan-Meier method and significance assessed using the log-rank statistic. Cox's Proportional Hazards Model was used to construct univariate and multivariate survival models. RESULTS AND CONCLUSIONS Overall median survival of 121 included patients was 13.2 (11.0 to 14.9) months and estimated 4 year survival was 13 +/- 6%. In a univariate analysis, the presence of visceral metastases and a hemoglobin < 12.5 mg/dl had significant adverse prognostic implications (P < 0.001 and P = 0.02, respectively). Performance status was not a significant predictor of survival, perhaps due to the fact that only 14% of patients had a performance status of 2. In a multivariate analysis, only the absence of visceral metastases retained its prognostic importance with an estimated 24% 4-year survival in such patients. These results lend further evidence for the clinical benefit of this regimen in advanced transitional cell cancer.

Abstract
PURPOSE We investigated the feasibility, safety, and antitumor activity of weekly gemcitabine given in combination with low doses of cisplatin and ifosfamide in previously treated patients with advanced transitional-cell carcinoma (TCC) of the urothelium. PATIENTS AND METHODS Patients with measurable, metastatic or unresectable TCC who had received one or two prior chemotherapy regimens were eligible. On a 28-day course, doses of cisplatin 30 mg/m(2), gemcitabine 800 mg/m(2), and ifosfamide 1 g/m(2) were given on day 1 and then repeated on day 8 and day 15 unless there was dose-limiting hematologic toxicity. RESULTS Fifty-one patients were registered; 10 patients participated in a pilot study, after which 41 patients were registered onto the phase II protocol. Forty-eight patients (94.1%) had dose-limiting hematologic toxicity on day 8 or day 15. Nonhematologic toxicity of grade 3 or greater consisted mainly of nausea and vomiting (seven patients, 13.7%) and infection (seven patients, 13.7%). Responses could be assessed in 49 of 51 eligible patients; two complete responses (4.1%) and 18 partial responses (36.7%) were observed for an overall response rate of 40.8% (exact 95% confidence interval, 27% to 56%). CONCLUSION This regimen of cisplatin, gemcitabine, and ifosfamide is not feasible for weekly administration because of hematologic toxicity. Nevertheless, there was promising activity with only two doses per 28-day cycle. On the basis of these results, we have initiated a phase II trial of this combination given as a single dose every 14 days in patients with untreated, metastatic urothelial carcinoma.

Abstract
The combination of methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) has dominated the landscape of chemotherapy for advanced bladder cancer for over 15 years. Randomized studies have shown its superiority over cisplatin alone or in combination with cyclophosphamide and doxorubicin. However, it exhibits a significant toxicity profile and achieves only a slight impact on overall survival. Gemcitabine is among the new cytotoxic drugs in development for treatment of advanced urothelial cancer. The combination of gemcitabine and cisplatin represents a new standard alternative of treatment in the disease based on similar efficacy to and lower toxicity than the classic MVAC regimen. Future drug development will focus on the clinical usefulness of three-drug regimens (including gemcitabine, paclitaxel or docetaxel, and a platinum salt), and nonplatinum-based combinations, as well as showing the impact of adjuvant postcystectomy chemotherapy on survival.

Abstract
PURPOSE To investigate the feasibility and pharmacokinetics of the combination cisplatin, gemcitabine, and SU5416. PATIENTS AND METHODS Patients received cisplatin 80 mg/m(2) on day 1, gemcitabine 1,250 mg/m(2) on days 1 and 8, repeated every 3 weeks, and SU5416 (85 and 145 mg/m(2)) intravenously twice weekly. Pharmacokinetics of all three agents, side effects, and antitumor response were investigated in patients with solid tumors amenable to therapy with cisplatin/gemcitabine. RESULTS In the first cohort of three patients entered at the 85 mg/m(2) dose, no dose-limiting toxicities were observed. In the next cohort (145 mg/m(2)), three patients developed a thromboembolic event. After entry was restricted to patients with low thromboembolic risk, three additional patients enrolled at 145 mg/m(2) developed a thromboembolic event. The dose was then reduced to 85 mg/m(2) in all patients still on the study, and three additional patients were entered on this dose level. In 19 treated patients, eight patients developed nine thromboembolic events (three transient ischemic attacks, two cerebrovascular accidents, and four deep venous thromboses). The most common toxicities observed were those previously reported for SU5416 alone (headache and phlebitis) and for this chemotherapy regimen (nausea, thrombocytopenia, and leucopenia). No significant pharmacologic interaction among the three drugs was observed. Response rates were similar to those expected in the patient population selected for this study. Analysis of variables of the coagulation cascade and of vessel wall activation was performed in three patients and showed significant increases in thrombin generation and endothelial cell perturbation in a treatment cycle-dependent manner. CONCLUSION The incidence of thromboembolic events, possibly related to the particular regimen tested in this study, discourages further investigation of this regimen.

Abstract
Pemetrexed (Alimta, LY231514) is a novel, multitargeted antifolate that is broadly active in a wide variety of solid tumors, including genitourinary malignancies. This agent has also shown clinically relevant activity in combination with other agents, including gemcitabine (Gemzar; Eli Lilly and Company, Indianapolis, IN). Further investigation is warranted in advanced disease and adjuvant settings.

Abstract
PURPOSE To evaluate the efficacy and toxicity of a combination of weekly docetaxel, gemcitabine and cisplatin in advanced transitional cell carcinoma (TCC) of the bladder. PATIENTS AND METHODS Thirty-five chemotherapy-naïve (adjuvant and neoadjuvant chemotherapy was allowed) patients with advanced TCC received intravenous docetaxel 35 mg/m2, gemcitabine 800 mg/m2 and cisplatin 35 mg/m2, on days 1 and 8 every 3 weeks. Prophylactic granulocyte-colony stimulating factor was given from days 3 to 6 and days 10 to 15, anti-emetics were used routinely. RESULTS Most (27) patients (77.1%) had a performance status of 0 to 1 and eight (22.9%) had received prior adjuvant or neoadjuvant cisplatin-based chemotherapy. In the intention-to-treat analysis, the objective response rate was 65.6% [23/35 patients, 95% confidence interval (CI) 47.8% to 80.9%]. Ten patients (28.5%) achieved a complete response (95% CI 14.6% to 46.3%) and 13 (37.1%) a partial response (95% CI 21.5% to 55.0%). Median survival time was 15.5 months, median duration of response was 10.2 months and median time to progression was 8.9 months. Ten patients (28.5%) developed grade 3/4 neutropenia, including five (14.3%) who experienced febrile neutropenia, which was successfully treated. Grade 3/4 anaemia and thrombocytopenia occurred in 20% and 25.7% of patients, respectively; four patients required platelet transfusions. There were no treatment-related deaths. CONCLUSIONS Weekly docetaxel, gemcitabine plus cisplatin is a highly effective treatment for chemotherapy-naïve advanced TCC, and causes only moderate toxicity. This regimen should be considered as a suitable option that deserves further prospective evaluation through randomised phase III trials.

Abstract
Gemcitabine was identified as an active agent in the treatment of urothelial cancer early in its clinical development. A gemcitabine/cisplatin regimen has been shown to lead to comparable survival in a phase III comparison to methotrexate/vinblastine/doxorubicin/cisplatin in the metastatic setting with less toxicity. Nonetheless, cisplatin-related toxicity is not inconsequential. Renal insufficiency limits wide applicability and long-term survival remains poor. A number of additional doublet combinations have thus been investigated. Substitution of carboplatin for cisplatin is feasible but leads to an apparent lower complete response rate. Likewise, combinations of gemcitabine and a taxane are feasible, but with somewhat discouraging response rates. A combination of doxorubicin and gemcitabine has been reported to lead to a 36% complete response rate, but this has not been confirmed. Combinations with targeted therapeutic agents such as the epidermal growth factor receptor inhibitors and trastuzumab have great potential, but the clinical studies have not yet been completed.

Abstract
The methotrexate/vinblastine/doxorubicin/cisplatin (MVAC) regimen has been the standard treatment in patients with locally advanced and metastatic urothelial cancer for the past 15 years. The minimal or moderate survival benefit-depending on prognostic features-and the severe toxicity associated with the MVAC regimen have made the search for new drugs and drug combinations of utmost importance to increase efficacy and/or decrease toxicity. In this respect, the taxanes and gemcitabine are promising new drugs. Paclitaxel and docetaxel as single agents have yielded overall response rates of 7% to 56%, depending on whether the patients have received prior chemotherapy for metastatic disease. The combination of paclitaxel and cisplatin has been explored in three studies with a total of 104 evaluable patients, a pooled overall response (OR) rate of 61%, and a complete response (CR) rate of 20%. There are two studies of docetaxel and cisplatin with a total of 91 evaluable patients, an OR rate of 54%, and a CR rate of 16%. The OR rate for paclitaxel and carboplatin in six studies was 43%, with a CR rate of 13%; however, the reported median survival was only 8.5 to 9.5 months. The OR rate for single-agent gemcitabine based on five studies was 26%, with a CR rate of 9%, which was apparently independent of whether the patients had received prior chemotherapy. The OR rate for gemcitabine and cisplatin in four phase II studies ranged from 41% to 57%, with a CR rate of 15% to 22% and a median survival of 12.5 to 14.3 months. Based on the encouraging results for the combination of gemcitabine and cisplatin (GC), a randomized phase III trial comparing GC and MVAC was begun in late 1996. This study of 405 randomized patients showed that the two regimens were associated with similar response rates, time to progression, and overall survival, whereas GC was associated with less toxicity than MVAC. On the basis of this superior risk-benefit ratio, the GC regimen should be favored as a new standard treatment in patients with locally advanced and metastatic urothelial cancer. Other promising combinations include gemcitabine and paclitaxel, with or without cisplatin, and the combination of ifosfamide, paclitaxel, and cisplatin. The triple combination of gemcitabine, paclitaxel, and cisplatin has yielded an OR rate of 78%, a CR rate of 28%, and a median survival of 24 months. An international phase III trial comparing this triple combination with GC in patients with locally advanced and metastatic urothelial cancer has now been initiated.

Abstract
Chemotherapy has been the cornerstone of treatment of advanced urothelial cancer. For a decade, the combination regimen of methotrexate/vinblastine/doxorubicin/cisplatin has been considered the standard for these patients. The need for improved efficacy and reduced toxicity of a predominantly palliative therapy has propelled efforts for new drug development. Of the newly identified agents with documented activity, both gemcitabine and paclitaxel have been evaluated with a platinum and have been incorporated into multiagent chemotherapy combinations. Phase II data from two gemcitabine-based triplets are currently available. Combination gemcitabine/paclitaxel/cisplatin and gemcitabine/paclitaxel/carboplatin have high levels of activity with overall and complete response rates of 76% and 26%, respectively, for the former and 68% and 32%, respectively, for the latter combination. The role of gemcitabine-based multiagent combinations compared with standard therapy awaits evaluation in prospectively randomized trials.

Abstract
A multicentre phase II trial was undertaken to evaluate the activity and toxicity of docetaxel plus cisplatin as first-line chemotherapy in patients with urothelial cancer. Thirty-eight patients with locally advanced or metastatic transitional-cell carcinoma of the bladder, renal pelvis or ureter received the combination of docetaxel 75 mg m(-2) and cisplatin 75 mg m(-2) on day 1 and repeated every 21 days, to a maximum of six cycles. The median delivered dose-intensity was 98% (range 79-102%) of the planned dose for both drugs. There were seven complete responses and 15 partial responses, for and overall response rate of 58% (95% CI, 41-74%). Responses were even seen in three patients with hepatic metastases. The median time to progression was 6.9 months, and the median overall survival was 10.4 months. Two patients who achieved CR status remain free of disease at 4 and 3 years respectively. Grade 3-4 granulocytopenia occurred in 27 patients, resulting in five episodes of febrile neutropenia. There was one toxic death in a patient with grade 4 granulocytopenia who developed acute abdomen. Grade 3-4 thrombocytopenia was rare (one patient). Other grade 3-4 toxicities observed were anaemia (three patients), vomiting (five patients), diarrhoea (four patients), peripheral neuropathy (two patients) and non-neutropenic infections (seven patients). Docetaxel plus cisplatin is an effective and well-tolerated regimen for the treatment of advanced urothelial cancer, and warrants further investigation.

Abstract
For the purpose of a subsequent phase II/III European Organization for Research and Treatment of Cancer (EORTC) trial, a gemcitabine/carboplatin feasibility study in "unfit" patients with advanced urothelial cell cancer was conducted. Gemcitabine was given at 1000 mg/m(2) days 1 and 8 with carboplatin (area under the curve (AUC) 4.5 or 5) day 1 every 21 days. 16 patients were treated, median age 68 years (47-75) years, performance status (PS) 0/1/2 in 3/10/3 patients. Creatinine clearance was >1 ml/s in 3 patients, 0.5-1 ml/s in 9 and <0.5 ml/s in 4 patients. Half of the patients had visceral disease. Median number of cycles given was 4 (range 2-6), for a total of 69 cycles. The first 8 patients received 33 cycles using a carboplatin AUC of 5. World Health Organization (WHO) grade 3-4 toxicity was: haemoglobin 5 patients, platelets 6 patients, neutrophils 5 patients and febrile neutropenia 2 patients. In view of this haematological toxicity in subsequent patients, the carboplatin AUC was decreased to 4.5. At this dose level, 8 patients received 36 cycles. WHO grade 3-4 toxicity was: anaemia 1 patient, platelets 4 patients, neutrophils 4 patients with no febrile neutropenia. Thus, this dose level was regarded to be feasible. For the 16 evaluable patients, overall response rate was 44%, (1 complete response (CR), 6 partial response (PR)). In conclusion, the combination of gemcitabine with carboplatin at an AUC of 4.5 appears to be an active and well tolerated regimen with acceptable toxicity in this unfit patient population. Based on these data, a randomised trial in the framework of the EORTC-Genitourinary (GU) group of gemcitabine/carboplatin versus carboplatin/methotrexate/vinblastine (MCAVI) is ongoing.

Abstract
PURPOSE To determine the efficacy and toxicity of the drug combination of carboplatin, paclitaxel, and gemcitabine in patients with advanced urothelial carcinoma. PATIENTS AND METHODS Patients eligible included those with advanced urothelial malignancy of any histology, no previous chemotherapy for metastatic disease, Southwest Oncology Group performance status of 2 or less, serum creatinine levels of 2 mg/dL or less, and adequate bone marrow and hepatic function. Treatment consisted of paclitaxel 200 mg/m2, carboplatin (target area under the curve = 5) on day 1, and gemcitabine 800 mg/m2 on days 1 and 8, repeated every 21 days. RESULTS Forty-nine patients (44 men and five women) were enrolled; the patients' median age was 63 years, and their median creatinine clearance was 78 mL/min (range, 26 to 165 mL/min). Forty-three patients had transitional cell carcinoma, and six had squamous cell carcinoma or mixed histology. Ten patients had metastases to lymph nodes only, six had locally advanced disease, four had locally recurrent disease, 24 patients had visceral metastases, and five had soft tissue metastases. Twenty-one patients had disease in one site, 16 in two sites, and 12 in three sites. A total of 272 cycles were administered (median, six cycles; range, 1 to 15 cycles). Major toxicities were grade 3 and 4 neutropenia in 17 and 19 patients, respectively; grade 3 and 4 thrombocytopenia in 15 and six patients, respectively; grade 3 and 4 anemia in 10 and two patients, respectively; grade 3 neuropathy in four patients; and diarrhea in two patients. The incidence of febrile neutropenia was 1.4%; no patients died of drug toxicity. Forty-seven of the 49 patients were assessable for response. Fifteen (32%) patients experienced a complete response, and 17 (36%) patients experienced a partial response (32 of 47 patients, 68%; 95% confidence interval, 56.27 to 82.86). Responses were seen in all sites, including 15 (68%) of 22 patients with visceral metastases. The median survival was 14.7 months, with a 1-year survival of 59%. CONCLUSION Combination paclitaxel, carboplatin, and gemcitabine is active; an encouraging number of patients with advanced urothelial carcinoma treated with this regimen experienced complete remission.

Abstract
BACKGROUND Cisplatin-based chemoradiation for locally advanced cervical carcinoma is now the standard of care for most patients with cervical carcinoma. However, induction chemotherapy followed by surgery, particularly with newer agents or combinations remains to be explored. This study was undertaken to evaluate the antitumor activity and toxicity of gemcitabine in combination with cisplatin for untreated locally advanced cervical carcinoma. PATIENTS AND METHODS Open-label, single center, phase II, non-randomized study of neoadjuvant gemcitabine plus cisplatin. Forty-one patients with histologic diagnosis of cervical carcinoma, with no previous treatment and staged as IB2 to IIIB, were treated with three 21-day courses of cisplatin 100 mg/m2 day I and gemcitabine 1000 mg/m2 days 1 and 8, followed by locoregional treatment with either surgery or concomitant chemoradiation. Response and toxicity were evaluated before each course and at the end of chemotherapy. RESULTS All patients were evaluated for toxicity and 40 for response. The overall objective response rate was 95% (95% confidence interval (CI): 88%-100%) being complete in 3 patients (7.5%) and partial in 35 (87.5%). A complete pathological response was found in 6 (26%) of the 23 patients that underwent surgery. Granulocytopenia grades 3-4 occurred in 13.8% and 3.4% of the courses, respectively, whereas non-hematological toxicity was mild. CONCLUSIONS Induction chemotherapy with the combination of gemcitabine and cisplatin is highly active for untreated cervical cancer patients and has an acceptable toxicity profile.

Abstract
PURPOSE Gemcitabine plus cisplatin (GC) and methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) were compared in patients with locally advanced or metastatic transitional-cell carcinoma (TCC) of the urothelium. PATIENTS AND METHODS Patients with stage IV TCC and no prior systemic chemotherapy were randomized to GC (gemcitabine 1,000 mg/m2 days 1, 8 and 15; cisplatin 70 mg/m2 day 2) or standard MVAC every 28 days for a maximum of six cycles. RESULTS Four hundred five patients were randomized (GC, n = 203; MVAC, n = 202). The groups were well-balanced with respect to prognostic factors. Overall survival was similar on both arms (hazards ratio [HR], 1.04; 95% confidence interval [CI], 0.82 to 1.32; P = .75), as were time to progressive disease (HR, 1.05; 95% CI, 0.85 to 1.30), time to treatment failure (HR, 0.89; 95% CI 0.72 to 1.10), and response rate (GC, 49%; MVAC, 46%). More GC patients completed six cycles of therapy, with fewer dose adjustments. The toxic death rate was 1% on the GC arm and 3% on the MVAC arm. More GC than MVAC patients had grade 3/4 anemia (27% v 18%, respectively), and thrombocytopenia (57% v 21%, respectively). On both arms, the RBC transfusion rate was 13 of 100 cycles and grade 3/4 hemorrhage or hematuria was 2%; the platelet transfusion rate was four patients per 100 cycles and two patients per 100 cycles on GC and MVAC, respectively. More MVAC patients, compared with GC patients, had grade 3/4 neutropenia (82% v 71%, respectively), neutropenic fever (14% v 2%, respectively), neutropenic sepsis (12% v 1%, respectively), and grade 3/4 mucositis (22% v 1%, respectively) and alopecia (55% v 11%, respectively). Quality of life was maintained during treatment on both arms; however, more patients on GC fared better regarding weight, performance status, and fatigue. CONCLUSION GC provides a similar survival advantage to MVAC with a better safety profile and tolerability. This better-risk benefit ratio should change the standard of care for patients with locally advanced and metastatic TCC from MVAC to GC.

Abstract
Transitional cell carcinoma (TCC) of the urothelium is a highly chemosensitive tumour. Combination chemotherapy can provide both palliation and a modest survival advantage in patients with advanced disease. At present, the combination of cisplatin, methotrexate, doxorubicin and vinblastine (M-VAC) is the most widely used for advanced TCC with an overall response rate of 40-72% in phase II, and 35-45% in phase III studies, and a median survival of approximately 12 months. These modest results and the unsuccessful attempts to increase efficacy with dose intensive M-VAC schedules have prompted the identification of new active agents in TCC, such as the taxanes and gemcitabine. The overall response rates for two-drug regimens of cisplatin-paclitaxel, carboplatin-paclitaxel and cisplatin-gemcitabine range from 63 to 72%, 14 to 65% and 42 to 66%, respectively. The overall response rates for platinum-paclitaxel-gemcitabine three-drug regimens range from 58 to 80%. The potential clinical benefit of these new three-drug combinations in the treatment of TCC needs to be tested in future phase III studies.

Abstract
Although transitional cell carcinoma of the urothelium is chemosensitive, long-term disease-free survival is low. Accordingly, interest has focused on combining classically active agents like cisplatin with promising new drugs. Gemcitabine has evoked interest not only because of its intrinsic activity against this cancer, but also because of its effect of inhibiting repair of DNA that has been damaged by drugs like cisplatin. Four phase II studies have assessed the effect of a gemcitabine-cisplatin combination on advanced or metastatic bladder cancer. All the studies employed a gemcitabine dose of 1000 mg/m(2) given on days 1, 8 and 15, whereas the cisplatin dose and schedule varied, with total doses ranging from 70 to 105 mg/m(2). Overall response rates in these studies ranged from 42 to 66%, with complete responses from 15 to 28%. Toxicities, which were primarily haematological, were generally manageable. This promising two-drug combination has been compared with the standard MVAC regimen (methotrexate, vinblastine, doxorubicin, and cisplatin) in a randomised phase III trial and the results are eagerly anticipated.

Abstract
Gemcitabine is a promising new drug in patients with locally advanced and/or metastatic transitional cell carcinoma of the urothelium. The drug has been tested as a single-agent in one phase I study and four phase II studies. Gemcitabine was administered on days 1, 8 and 15 every 28 days with a dose in the phase II studies ranging from 1000 to 1250 mg/m(2). Response rates for single-agent gemcitabine in as well previously untreated as cisplatin-based pretreated patients ranged from 23 to 29% with CR rates between 4 and 13%. Toxicities were mild to modest and generally without grade 4 toxicities. The combination of gemcitabine and cisplatin has been tested in three phase II studies. Gemcitabine was administered in a dose of 1000 mg/m(2) on days 1, 8 and 15 every 28 days whereas the cisplatin dose and schedule varied. In one study, cisplatin was given in a dose of 35 mg/m(2) on days 1, 8, and 15 together with gemcitabine; in the two other studies in a dose of 70-75 mg/m(2) on day 1 or 2 in each treatment course. The response rates ranged from 42 to 66% with CR rates of 18, 21 and 28%. Median survival was reported in two of the studies, 12.5 and 13.2 months, respectively. Toxicities were generally manageable although the weekly schedule of cisplatin resulted in a high degree of grade 3-4 neutropenia and thrombocytopenia. Thus, the schedule has been optimized by use of monthly cisplatin in a dose of 70 to 75 mg/m(2). The two-drug combination of gemcitabine and cisplatin has also been compared with MVAC in a randomized phase III trial. Gemcitabine was administered in a dose of 1000 mg/m(2) on days 1, 8 and 15 and cisplatin in a dose of 70 mg/m(2) on day 2 every 28 days. The study was initiated late in 1996 and the planned recruitment of 400 patients was reached at the end of October 1998. The results are now eagerly awaited. Preliminary results for gemcitabine tested in two- and three-drug combinations with new agents such as paclitaxel have indicated response rates of up to 79% and these combinations should be further explored.
