Brief Summary

The purpose of this study is to evaluate the effect of two anti-inflammatory drugs, fish oil capsules and the COX-2 inhibitor celecoxib, on pregnancy associated breast cancer (PABC). Short-term intervention with anti-inflammatory medications will demonstrate a reduction in the inflammation and immune suppressive phenotype of PABC, and decreased metastatic potential in PABC. This unique window in breast cancer management serves as a valuable opportunity to obtain preliminary data on biomarkers and the alterations that occur when the system is troubled by a drug or other intervention which will be instrumental in designing future therapeutic or preventative strategies for larger clinical study.

Conditions

Stage IIIA Breast Cancer; Stage IIIB Breast Cancer; Stage IA Breast Cancer; Stage IB Breast Cancer; Stage II Breast Cancer; Stage IIIC Breast Cancer; Stage IV Breast Cancer

Keywords

Breast cancer; Omega-3 Fatty Acid; Celecoxib; Celebrex; Surgery

Outcome Measures

Primary Outcomes (1)

• Change in mean Ki-67 index in patients receiving either omega-3 fatty acid or celecoxib for 1 or more weeks as compared to controls

  Tumor cells are stained using the Ki-67 monoclonal antibody. Ki-67 is measured as a percentage of positive tumor cells. The investigator will conduct three paired t-tests comparing the percent Ki-67 at baseline to the percent Ki-67 after treatment. There will be one t-test for each arm.

  Baseline and 1 week

Study Arms (3)

Arm I

NO INTERVENTION

Patients undergo observation.

Arm II (fish oil)

EXPERIMENTAL

Patients receive omega-3 fatty acid by mouth everyday until the morning of surgery.

Dietary Supplement: Omega-3 fatty acid

Arm III (celecoxib)

EXPERIMENTAL

Patients receive celecoxib by mouth twice a day until the morning of surgery.

Drug: Celecoxib

Interventions

Omega-3 fatty acid DIETARY_SUPPLEMENT

Given PO

Also known as: fish oil, n-3 fatty acid, omega-3 polyunsaturated fatty acid

Arm II (fish oil)

Celecoxib DRUG

Given PO

Also known as: Celebrex

Arm III (celecoxib)

Eligibility Criteria

• Age: 18 Years - 50 Years
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Age greater or equal to 18 and less than or equal to 50.
• Histological or cytological confirmation of breast cancer; for patients with fine needle aspiration (FNA), a core biopsy must be intended
• For patients diagnosed with needle core or excisional biopsy, formalin-fixed paraffin embedded tumor blocks or unstained slides must be available or patient must be willing to undergo repeat core biopsy for research purposes as part of study procedures (biopsy for fresh/ fresh frozen tissue is otherwise optional)
• Any clinical stage allowed provided definitive local resection intended and neoadjuvant treatment not intended
• Patient must be planned to proceed to definitive surgery for their breast cancer at least 1 week or more after diagnosis
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
• Patient must have laboratory parameters as follows:
• Liver function tests (Total bilirubin, aspartate aminotransferase, alanine aminotrasferase, alkaline phasphataseAST) =\< 2 x ULN
• Platelet count greater than or equal to institutional lower limit of normal (LLN)
• Patient cannot have greater than grade 1 anemia as determined by hematocrit (Hct)
• Written informed consent obtained prior to any initiation of study procedures
• Willingness to abstain from either fish oil or celebrex for study period if randomized to control arm
• Women who are lactating at time of diagnosis are eligible provided they complete weaning prior to starting study drug

You may not qualify if:

• Known autoimmune condition, chronic steroid use, underlying immune disease (other than breast cancer), use of immunomodulatory prescription drugs for any medical condition
• Known allergy or intolerance to fish oil, fish, non-steroidal anti-inflammatory drugs (NSAIDS), acetylsalicylic acid (ASA) or cyclooxygenase-2 (COX 2) inhibitors
• Known bleeding diathesis or history of peptic ulcer disease; gastroesophageal reflux allowed if controlled
• Currently taking greater than one 1000mg fish oil capsule daily or celecoxib at baseline, unless willing to stop consumption 1 week prior to starting study
• History of stroke, transient ischemic attack (TIA) or coronary artery disease
• The presence of other comorbid conditions known to impact immune function, (such as: type I diabetes, uncontrolled adult onset diabetes, severe chronic obstructive pulmonary disease (COPD), uncontrolled infection or known human immunodeficiency virus \[HIV\] infection)
• Underlying psychiatric condition which would, in the opinion of the investigator, preclude compliance with study requirements
• Women who are pregnant at time of breast cancer diagnosis and intend to continue the pregnancy; if pregnancy is terminated per patient's cancer decision making, they would be eligible for participation afterwards
• History of other malignancy besides current diagnosis of breast cancer, unless definitively treated more than 5 years ago
• Any history of Hodgkin's disease requiring mantle field irradiation
• Any previous diagnosis of breast cancer
