The Effect of Aspirin on Mammogram Density (TEAM)


OBJECTIVES:

Primary

- Compare the effect of acetylsalicylic acid (aspirin) vs placebo on mammographic density
in healthy postmenopausal women with a moderate or high level of breast density.

Secondary

- Determine whether there is a differential response in mammogram density to aspirin
treatments in individual homozygous wild-type, heterozygous, and homozygous variant for
several UGT gene polymorphisms.

- Determine the effect of aspirin therapy on potential adverse events, including
gastrointestinal symptoms and signs, bleeding events, blood pressure, and other major
comorbidities and hospitalizations, as well as generalized symptoms, in these
participants.

- Determine the effects of aspirin therapy on putative biomarkers of breast and ovarian
cancer that are currently being validated as part of ongoing Fred Hutchinson Cancer
Research Center Ovarian SPORE activities.

- Determine the effects of aspirin therapy on levels of serum estradiol, estrone and sex
hormone binding globulin (SHBG) as measured by radioimmunoassay at baseline and 6
month timepoints

OUTLINE: This is a randomized, placebo-controlled, double-blind study. Participants are
randomized to 1 of 2 treatment arms.

- Arm I: Participants receive oral acetylsalicylic acid (aspirin) daily for 6 months.

- Arm II: Participants receive oral placebo daily for 6 months. In both arms,
participants undergo a repeat mammogram at 6 months.

Blood and urine samples are collected at baseline and at 6 months. Single-nucleotide
polymorphisms in the UGT genes and variable number of tandem repeat-type polymorphisms are
genotyped.

PROJECTED ACCRUAL: A total of 144 participants will be accrued for this study.
