DISEASE CHARACTERISTICS:

• Histologically confirmed locally advanced or metastatic colorectal cancer
• Metastatic disease must be radiologically proven
• HLA-A2-1 positive
• Locally advanced disease must have had prior resection or incomplete resection with poor prognosis

• Locally advanced disease includes:

  • Stage III or IV colon cancer (T4 or any T, N2-3, M0)
  • Stage III or IV rectal cancer (T4 or T3, N1-3)
  • Resectable or unresectable T4 disease after radiotherapy, chemotherapy, and/or surgery
  • Absence of measurable disease but more than a 50% chance of recurrence
• Completely resected or locally advanced disease may have had conventional therapy completed within 1-12 months (surgery alone, with or without adjuvant chemotherapy and/or radiotherapy) prior to study entry

• Metastatic disease patients must have bidimensionally measurable disease

  • Bone lesions with well-demarcated borders allowed
  • Lesions seen only on bone scan, pleural effusions, ascites, and changes in carcinoembryonic antigen are not considered measurable disease
