PRIMARY OBJECTIVE:
I. To test for the equivalency of the two aspirin schedules.
SECONDARY OBJECTIVES:
I. To evaluate the effects of aspirin treatments on:
Ia. The ratio of cell proliferation (Ki-67)/apoptosis (TUNEL) in rectal biopsies.
Ib. The ratio of cell proliferation (Ki-67)/necroptosis (MLKL) in rectal biopsies.
Ic. Fecal occult blood test (measures of adverse events) as measured by stool samples.
Id. Methylation biomarkers in genes (i.e. CDKN2A [cell cycle regulation], MGMT [deoxyribonucleic acid (DNA) repair], DAPK1 [apoptosis], CDH1 [cell invasion], WNT16 [Wnt pathway] and RASSF1 [RAS signaling]) involved in colorectal carcinogenesis, as measured in rectal biopsies.
Ie. Abundance of Escherichia (E.) coli and Fusobacterium in rectal swabs. II. To evaluate if the effects of aspirin arms may be modified by dietary intake of calcium as measured by the Food Frequency Questionnaire (FFQ).
OUTLINE: Patients are randomized to 1 of 3 arms.
ARM I: Patients receive aspirin orally (PO) daily for 12 weeks in the absence of unacceptable toxicity.
ARM II: Patients receive aspirin PO daily at weeks 1-3 and 7-9 and placebo PO daily at weeks 4-6 and 10-12 in the absence of unacceptable toxicity.
ARM III: Patients receive placebo PO daily for 12 weeks in the absence of unacceptable toxicity.
After completion of study, patients are followed up at 1 month.

- Ratio of cell proliferation to apoptosis biomarkers (Ki67 index and BAX index) [ Time Frame: Up to 3 months ]
- Ratio of cell proliferation (Ki-67)/apoptosis (TdT-mediated dUTP nick end labeling [TUNEL]) assessed in rectal biopsies [ Time Frame: Up to 12 weeks ]All of these variables will be described using appropriate statistics such as means (for continuous) and proportions (for discrete outcomes). Typically, basic scientists like to present the data to each other as bar graphs with standard deviation/standard error bars. Such and other, more appropriate graphic presentations, as confidence intervals for the true mean or true proportion will be provided, as well as scatter plots presenting two variables relationship in the Cartesian axes context. Tests of difference for continuous data (t-test, Wilcoxon test) and of association for discrete data (Chi-square, Fisher) will be provided.

- The effects of aspirin on the developing human fetus at the recommended therapeutic dose are unknown; for this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately
- Ability to understand and the willingness to sign a written informed consent document
Exclusion Criteria:

- Aspirin, other nonsteroidal anti-inflammatory drugs (NSAIDs), or COX-2 inhibitors
- Anticoagulants, anti-platelet agents, or corticosteroids
- Gingko
- Ethanol consumption > 1 standard drinks/day for women, or > 2 standard drinks/day for men
- Methotrexate (MTX)
- Study participants will be instructed to use Tylenol or some other non-excluded agent to treat common ailments (i.e. headache/minor aches and pains)
-
History of
- Any invasive malignancy within the past 2 years, with the exception of non-melanoma skin cancer
- Chronic renal diseases or liver cirrhosis
- Diseases such as anemia, peptic ulcer, gastrointestinal bleeding, active colitis and inflammatory bowel disease

- History of allergic reactions or intolerance attributed to aspirin or compounds of similar chemical or biologic composition
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness that would limit compliance with study requirements
- Women who are pregnant or breastfeeding; pregnant women are excluded from this study because aspirin has the potential for abortifacient effects; because there is an unknown but potential risk for adverse events (AEs) in nursing infants secondary to treatment of the mother with aspirin, breastfeeding should be discontinued if the mother is treated with aspirin
