Clinical Trial Summary
This randomized phase III trial studies how well aspirin works in preventing the cancer from
coming back (recurrence) in patients with human epidermal growth factor receptor 2 (HER2)
negative breast cancer after chemotherapy, surgery, and/or radiation therapy. Aspirin is a
drug that reduces pain, fever, inflammation, and blood clotting. It is also being studied in
cancer prevention. Giving aspirin may reduce the rate of cancer recurrence in patients with
breast cancer.

Enrollment Eligibility
- Histologic documentation of women or men with node positive, HER2 negative, anatomic
stage II or III breast carcinoma and high risk node negative (defined as estrogen
receptor [ER] and progesterone receptor [PR] negative and tumor size > 2 cm) within
one year of diagnosis and free of recurrence; patients with pN1mic are eligible; if
neoadjuvant therapy was received, either initial clinical stage (determined by
physical and or radiologic examination) or post-operative pathologic stage can be used
for eligibility purposes, with the higher stage determining eligibility; histologic
documentation of node positivity is required; bilateral breast cancers are allowed, as
long as both cancers are HER2 negative and at least one of the cancers meets
eligibility
- Any ER/progesterone receptor (PgR) status allowed
- Prior adjuvant treatment with chemotherapy and/or endocrine therapy, as determined by
the treating physician, is allowed; the last dose of chemotherapy or radiation therapy
must be at least 30 days prior to study registration; concurrent hormonal therapy will
be allowed
- Regular nonsteroidal anti-inflammatory drug (NSAID)/aspirin use at any dose (including
baby aspirin) (defined as >= 5 days per week) is allowed if aspirin and/or NSAIDs are
stopped for 30 days prior to study entry and throughout the study period; participants
will be encouraged to use acetaminophen for minor pain and fever
- Patients must be enrolled within 1 year after diagnosis
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2
- Patients with a prior history of gastric/duodenal ulcers documented on endoscopy can
be enrolled as long as the ulcers did not cause bleeding requiring a blood
transfusion/major intervention; for patients who are Helicobacter pylori positive, a
course of Helicobacter pylori eradication treatment must have been completed
- No history of gastrointestinal bleeding (GI) bleeding requiring a blood transfusion,
endoscopic or operative intervention
- No history of any prior stroke (hemorrhagic or ischemic)
- No concurrent anticoagulation with warfarin or heparin/heparin analogues, clopidogrel,
oral direct thrombin inhibitors, or direct factor XA inhibitors
- No history of atrial fibrillation or myocardial infarction
- No history of grade 4 hypertension, defined as hypertension resulting in
life-threatening consequences (e.g., malignant hypertension, transient or permanent
neurologic deficit, hypertensive crisis)
- No chronic (duration > 30 days) daily use of oral steroids
- No known allergy to aspirin
- No prior malignancy of any type (including ductal breast carcinoma in situ [DCIS])
within the past 5 years except for current diagnosis of breast cancer, and any prior
diagnosis of basal or squamous cell carcinoma of the skin or carcinoma in situ of the
cervix; patients with a prior history of breast cancer greater than 5 years from study
screening may participate in this study
- Concurrent enrollment on a non-chemotherapy treatment trial will be allowed, as long
as that trial allows concurrent daily aspirin use
