Brief Summary
This randomized phase II trial is studying how well aspirin works in preventing colorectal cancer in patients at increased risk of colorectal cancer. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of aspirin may prevent colorectal cancer.

Outcome Measures
Primary Outcomes (2)
Change of a Spectral Biomarker for Colonic Carcinogenesis (Called Spectral Slope or SPEC) From Baseline to 3 Months.
Spectral marker assessment was performed via LEBS analysis (low-coherence enhanced backscattering spectroscopy) on the uninvolved mucosal biopsies of subjects taken at baseline and after 3 months of treatment with either aspirin or placebo. SPEC characterizes the size distribution of macromolecular complexes and other intracellular structures, with a decrease of the spectral slope implying a shift of the size distribution of intracellular structures toward smaller sizes. Spectral markers SPEC and FRAC provide a measure of the fundamental characteristics of the tissue nanoscale architecture.
3 months from baseline colonoscopy to end of intervention.
Change of a Spectral Biomarker for Colonic Carcinogenesis (Called Fractal Dimension or FRAC) From Baseline to 3 Months.
Spectral marker assessment was performed via LEBS analysis (low-coherence enhanced backscattering spectroscopy) on the uninvolved mucosal biopsies of subjects taken at baseline and after 3 months of treatment with either aspirin or placebo. FRAC characterizes the spatial autocorrelation function of mass density distribution in tissue. SPEC and FRAC provide a measure of the fundamental characteristics of the tissue nanoscale architecture
3 months from baseline colonoscopy to end of intervention.
Secondary Outcomes (3)
Colonic Epithelial Apoptosis as Measured by Immunohistochemical Detection of Cleaved Caspase 3
3 months from baseline colonoscopy to end of intervention.
Changes in Colonic Cell Proliferation as Measured by Immunohistochemical Detection of Ki67
3 months from baseline colonoscopy to end of intervention.
Rectal Prostaglandin Levels as Measured by ELISA
3 months from baseline colonoscopy to end of intervention.
Other Outcomes (1)
