RATIONALE: Vaccines made from the HER2/neu antigen may make the body build an immune response and kill tumor cells. Colony-stimulating factors such as GM-CSF increase the number of immune cells found in bone marrow or peripheral blood.
PURPOSE: Phase I trial to study the effectiveness of HER-2/neu vaccine plus GM-CSF in treating patients who have stage III or stage IV breast cancer, stage III or stage IV ovarian cancer, or stage III or stage IV non-small cell lung cancer.
OBJECTIVES: I. Determine the safety of serial intradermal vaccinations of HER-2/neu derived peptides with sargramostim (GM-CSF) as an adjuvant in patients with stage III or IV HER-2/neu expressing breast, ovarian, or nonsmall cell lung cancer. II. Determine whether immunity can be elicited with peptides derived from the intracellular domain of the HER-2/neu protein. III. Determine whether immunity can be elicited with peptides derived from the extracellular domain of the HER-2/neu protein. IV. Determine whether cytotoxic T cells specific for the HER-2/neu protein can be elicited in patients with HLA-A2 by immunization with peptides derived from the HER-2/neu protein.
OUTLINE: Patients receive one of three HER-2/neu peptide vaccine formulations that also contain sargramostim (GM-CSF) as the vaccine adjuvant. Each vaccine is studied in 20 patients. A maximum of 3 patients receive a vaccine each month for 6 months to monitor the potential toxicity associated with sequential immunizations. Patients receive a follow-up evaluation 1 month after the last vaccination. Those patients who have an immune response related to the vaccine will continue to have immunologic evaluations performed every 2 months while immune responses can still be detected.
PROJECTED ACCRUAL: 60 patients will be accrued.

A novel activating peptide was designed and synthesized from V. cholerae hemagglutinine protease (HAP) mediated cleavage site of mouse PAR1. The peptide "PFISED" interacts with PAR1 in a new site whic...
Iodine-125 labeled Australian frog tree host-defense peptides caerin 1.1 and 1.9 better inhibit human breast cancer cells growth than the unlabeled peptides. I-caerin 1.9 may better be used for the treatment of breast cancer.
We recently showed that host defense caerin peptides isolated from Australian frog tree were able to inhibit cervical cancer tumour cell growth in vitro. We wished to determine if radioactive isotope ...
Gene expression profiling of breast cancer has demonstrated the importance of stromal response in determining the prognosis of invasive breast cancer. The host response to breast cancer is of increasi...
Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).
Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.
A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.
Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Examples of antigens include microorganisms (such as bacteria, fungi, parasites, and viruses) and chemicals. Antibodies may be produc...
