Brief summary: Background:

* Many cancers produce two proteins, carcinoembryonic antigen (CEA) and mucin-1 (MUC-1).
* The PANVAC-V (PANVAC vaccinia) priming vaccine and PANVAC-F (PANVAC fowlpox) boosting vaccine contain human genes that cause production of CEA and MUC-1, which can be used as a target for the immune system to attack the cancer. The vaccines also contain genes that cause production of other proteins that enhance immune activity.
* Sargramostim is a protein that boosts the immune system.

Objectives:

* To evaluate the safety and effectiveness of PANVAC-V and PANVAC-F in patients with advanced cancer.
* To document the immune response to the vaccines and any anti-tumor responses that may occur.

Eligibility: Patients 18 years of age and older with advanced cancer whose tumors produce CEA or MUC-1 protein

Design:

* This trial has three cohorts: the first cohort includes 10 patients with advanced colorectal cancer and 10 to 15 patients with any advanced non-colorectal cancer that produces either EA or mitochondrial Ca2+ uniporter 1 (MCU-1); the second cohort includes 12 patients with advanced breast cancer and the third cohort includes 14 patients with advanced ovarian cancer.
* All patients receive PANVAC-V on study day 1, followed by PANVAC-F on days 15, 29 and 43 then every 28 days for up to 12 vaccines followed by every 3 months until disease progression or toxicity. The vaccines are given by injection under the skin. Sargramostim is injected at the vaccination site on the day of each vaccination and for the next 3 days following vaccination.
* Patients whose scans show that their disease has progressed, but who are otherwise clinically stable may revert back to monthly injections.
* Patients undergo apheresis to collect white blood cells (lymphocytes) on day 1 and day 71 of the study to measure the immune response to the treatment. Blood is collected through a needle placed in one arm and directed through a cell separator machine where the lymphocytes are extracted. The rest of the blood components are returned to the patient through the same needle.
* Patients are monitored with frequent blood tests and periodic imaging tests (scans) to monitor for safety and the response to treatment.

Detailed description: Background:

* Carcinoembryonic antigen (CEA) and mucin-1 (MUC-1) are overexpressed in multiple adenocarcinomas.
* Pox viral vectors can induce a strong immune response to CEA and MUC-1.
* The use of agonist epitopes within the tumor associated antigen (TAA) can induce a better immune response than native peptides and have been associated with clinical responses
* Heterologous prime and boost regimens are superior in terms of generalizing immune responses; and this may translate into improved clinical responses
* The use of granulocyte-macrophage colony-stimulating factor (GM-CSF) does not add significant toxicity and in pre-clinical models is essential for induction for optimal immune responses.
* It is possible by using vectors directed against TAA that there may be additive or synergistic immune responses and this may be important in overcoming antigenic escape variance
* Evidence of clinical benefit has been noted in some patients treated with this vaccine

Objectives:

* For colorectal cancer and non-colorectal cancer Cohort: To evaluate the safety and tolerability of the vaccine.
* For the Ovarian Cancer and Breast Cancer Cohorts: To evaluate clinical response to the vaccine.

Eligibility:

* In the first cohort (colorectal and non-colorectal cancer), histologically confirmed adenocarcinoma that is CEA or MUC-1 positive described as metastatic disease (measurable or evaluable) or metastatic disease documented by biopsy but not evaluable by imaging (e.g. small volume peritoneal disease)
* For the ovarian and breast cancer cohorts, patients must have evaluable disease
* Normal organ function, Eastern Cooperative Oncology Group (ECOG) 0-1

Design:

* This is a non-randomized three cohort, pilot trial of pox viral vaccines that contain the transgenes for CEA and MUC-1 (both with modified human leukocyte antigen A2 (HLA-A2) agonist epitopes) as well as 3 human T-cell costimulatory molecules, B7-1, ICAM-1 (CD54), and LFA-3 (CD58) \[PANVAC(TM)-V (vaccinia) and PANVAC(TM)-F (fowlpox)\] in patients with metastatic carcinoma that express CEA or MUC-1 antigen.
* The first cohort will enroll 10 patients with metastatic colorectal adenocarcinoma and 10-15 patients with any metastatic non-colorectal carcinoma that expresses either CEA or MUC-1. .
* The second cohort will enroll 12 patients with metastatic breast carcinoma and 14 patients with metastatic ovarian carcinoma.
* All patients will receive the same vaccines on the same schedule. PANVAC(TM)-V (vaccinia) subcutaneously (s.c.) scheduled on day 1, followed by PANVAC(TM)-F (fowlpox) s.c. scheduled on days 15, 29, and 43 then every 28 days for up to 12 vaccines followed by every 3 months until disease progression or toxicity.
* Sargramostim (100 micro g) will be given at the site of the vaccination (PANVAC-V and PANVAC-F) on each vaccination day and for three consecutive days thereafter.
* Patients who have radiographic evidence of progressive disease, but who are otherwise clinically stable may revert back to monthly vaccinations.

Eligibility criteria: * INCLUSION CRITERIA:

A. Histologically confirmed carcinoma that for patients in the first cohort (colorectal and non-colorectal cancer) is carcinoembryonic antigen (CEA) or mucin-1 (MUC-1) positive. Tumor that has been shown to express CEA or MUC-1 (greater than or equal to 20 % of cells) by immunohistochemical techniques or patients that have had an elevated serum CEA (greater than 5 microgram/L) at any point during their disease course. For patients in the ovarian and breast cancer cohorts, as greater than 95% of these express MUC-1 or CEA, we will not require staining prior to coming onto trial.

B. Patients must have completed at least one fluorouracil (5-FU) containing chemotherapy regimen (e.g. 5-FU/leucovorin (LV) with or without either irinotecan or oxaliplatin) for the colorectal cancer arm, or either failed or not be a candidate for therapy of proven efficacy for non-colorectal, breast, or ovarian cancer.

C. 18 years of age or greater.

D. All patients enrolled on the colorectal/non-colorectal cohort with colorectal adenocarcinoma cohort must be human leukocyte antigen A2 (HLA-A2) positive.

E. At least 10 patients enrolled on the colorectal/non-colorectal cohort with non-colorectal adenocarcinoma cohort must be HLA-A2 positive.

F. Patients in the breast cohort and the ovarian cohorts are not required to be HLA-A2 positive.

G. For the colorectal and non-colorectal cancer cohort, patients will be required to have: metastatic disease (measurable or evaluable), metastatic disease documented by biopsy but not evaluable by imaging (e.g. small volume peritoneal disease), and patients with surgically resected metastatic disease at high risk of relapse. For the ovarian cohort and the breast cancer cohort, patients will be required to have evaluable disease.

H. Able to understand and give informed consent.

L. Total bilirubin within the institution limits of normal OR patients with Gilbert's syndrome, a total bilirubin less than or equal to 3.0

M. Recovered completely from any reversible toxicity associated with recent therapy. Typically this is 3-4 weeks for patients who most recently received cytotoxic therapy except for the nitrosoureas and mitomycin C for which 6 weeks is needed for recovery.

EXCLUSION CRITERIA:

A. Patients should have no evidence of being immunocompromised as listed below.

* Human immunodeficiency virus positivity due to the potential for decreased tolerance and risk for severe side effects
* Active autoimmune diseases requiring treatment or a history of autoimmune disease that might be stimulated by vaccine treatment. This requirement is due to the potential risks of exacerbating autoimmunity. Patients with endocrine disease that is controlled by replacement therapy including thyroid disease and adrenal disease and vitiligo may be enrolled.
