The patients must be suffering from advanced/metastatic urotherial cancer after standard treatment. 2) Patients must be at a score level of 0-1 of performance status (PS)(EOCG) 3) Patients must have IgG reactive to at least two of candidate peptides. 4) Patients must be expected to survive more than 3 months. 5) Patients must satisfy the followings: WBC > 2,500/mm3 Lymphocyte > 1,000/mm3 Hb > 8.0g/dl Platelet > 80,000/mm3 Serum Creatinine < 2.5 x upper limit of normal Total Bilirubin < 2 x upper limit of normal 6) Patients must be more 20 year-old. 7) Written informed consent must be obtained from patients. 8) Patients must be positive for HLA-A2, HLA-A24, HLA-A26. or HLA-A3 super type.

Exclusion criteria

Exclusion criteria: The following patients must be excluded: 1) Patients with severe symptoms (active and severe infectious disease, circulatory disease, respiratory disease, kidney disease, immunodeficiency, disturbance of coagulation). 2) Patients with the past history of severe allergic reactions. 3) Patients do not accept contraception during the 1st vaccination to 70 days after the last vaccination. 4) Patients who are judged inappropriate for the clinical trial by doctors.

Design outcomes

Primary

Measure	Time frame
Evaluation of immunological responses (anti-peptide IgG) before and after peptide vaccination.	—

Secondary

Measure	Time frame
1. Evaluation of long-term prognosis (progression free survival and total survival). 2. Adverse effects of peptide vaccination / The safety of the protocol is evaluated based on the NCI-CTC.	—
