Brief Summary: RATIONALE: Vaccines made from a peptide may make the body build an immune response to kill cancer cells.
PURPOSE: This phase I trial is studying two different vaccines to treat patients who have gastric, prostate, or ovarian cancer.
Detailed Description: OBJECTIVES:
* Determine the toxicity of EGFRvIII peptide vaccine with sargramostim (GM-CSF) or keyhole limpet hemocyanin (KLH) as adjuvant in patients with EGFRvIII-expressing cancer. * Determine the preexisting antibody and T-cell responses to EGFRvIII in these patients. * Determine the antibody and T-cell responses to EGFRvIII peptide after immunization with this vaccine with GM-CSF or KLH as adjuvant.
OUTLINE: Patients are assigned to one of two treatment arms.
* Arm I: Patients receive a vaccine containing EGFRvIII peptide admixed with sargramostim (GM-CSF) intradermally monthly. * Arm II: Patients receive a vaccine containing EGFRvIII peptide admixed with keyhole limpet hemocyanin subcutaneously monthly.
Treatment in both arms continues for 6 months in the absence of disease progression or unacceptable toxicity.
Patients are followed every 3 months for 1 year.
PROJECTED ACCRUAL: A total of 24 patients (12 per treatment arm) will be accrued for this study.
