Trial of Paclitaxel Plus Gemcitabine and Cisplatin in Bladder Cancer

Inclusion Criteria: * All patients must have histologic demonstration of metastatic or locally unresectable transitional cell carcinoma of the urothelium. Minor components (\<50% overall) of variants such as glandular or squamous differentiation, or evolution to more aggressive phenotypes, such as sarcomatoid, or small cell changes are acceptable. However, when these atypical histologies are dominant, other treatment approaches may be more appropriate, and such patients are not eligible. * All patients must have measurable or evaluable disease. In general, liver and lung lesions should be at least 1 cm, and patients with node-only disease should have lesions of ≥ 1.5 cm in the largest dimension. Patients with disease confined to bone may be eligible if a measurable lytic defect is present. Patients with a 3-dimensional mass or pelvic sidewall fixation on bladder examination under anesthesia are considered to have measurable disease. * All patients must have adequate physiologic reserves as evidenced by: * Life expectancy of at least 12 weeks. * Eastern Cooperative Oncology Group (ECOG) performance status of ≤2. * No clinical history of heart disease and a normal EKG or an ejection fraction measured by echocardiogram or MUGA scan of at least 45%. * Transaminase less than twice the upper limit of normal. Bilirubin \<1.5 mg%. * Serum creatinine ≤2.0 mg/dL. Patients presenting with obstructive uropathy may be eligible if they show excellent response to nephrostomy drainage. * Absolute neutrophil count ≥1500; platelet count ≥100,000. * Patients must not have had any previous systemic chemotherapy for bladder cancer, including neoadjuvant or adjuvant treatment given remotely. Gemcitabine/cisplatin is the standard of care for metastatic urothelial cancer. Patients who have received treatment would be either resistant or refractory to additional doses. In addition, they would have residual adverse effects from treatment and would be particularly susceptible to further neuropathic adverse events. Any prior intravesicular therapy is allowed. * Women of childbearing potential must have a negative pregnancy test prior to starting therapy. Men and women of childbearing potential must be willing to consent using effective contraceptive while on treatment and for a reasonable period thereafter. * Patients must not have an active, or likely to become active, second malignancy. * Patients must be at least 6 weeks out from pelvic irradiation, and must not have had more than 10% of the bone marrow irradiated. Exclusion Criteria: * Patients with uncontrolled CNS metastasis are not eligible. * Patients with a history of peripheral neuropathy greater than grade 1 are not eligible. * Pregnant women are excluded.
