Randomized Controlled Trial Clinical Trial
Primary chemoprevention of familial adenomatous polyposis with sulindac.
Familial adenomatous polyposis is caused by a germ-line mutation in the adenomatous polyposis coli gene and is characterized by the development of hundreds of colorectal adenomas and, eventually, colorectal cancer. Nonsteroidal antiinflammatory drugs can cause regression of adenomas, but whether they can prevent adenomas is unknown. ⋯ Standard doses of sulindac did not prevent the development of adenomas in subjects with familial adenomatous polyposis.

Sequence variants in the gene encoding estrogen receptor alpha (ER-alpha) may modify the effects of hormone-replacement therapy on levels of high-density lipoprotein (HDL) cholesterol and other outcomes related to estrogen treatment in postmenopausal women. ⋯ Postmenopausal women with coronary disease who have the ER-alpha IVS1-401 C/C genotype, or several other closely related genotypes, have an augmented response of HDL cholesterol to hormone-replacement therapy.
