Summary of "Lipophilic statin use and risk of breast cancer subtypes."

Background/Aims: Statins are widely used and of high interest as potential chemopreventive agents for cancer. Preclinical studies suggest that lipophilic statins have anti-cancer properties targeting hormone receptor (HR)-negative breast cancer. Few epidemiologic studies have investigated the relationship between lipophilic statin use and risk of breast cancer, stratified by HR status. We conducted a large case-control study within the Kaiser Permanente of Northern California (KPNC) to determine whether chronic use of lipophilic statins is associated with decreased risk of HR-negative breast cancer, or other breast cancer subtypes.
METHODS:
We identified 22,488 breast cancer cases diagnosed during 1997-2007, and 224,860 controls matched to cases based upon birth year and duration of KPNC pharmacy coverage. Use of lipophilic statins was ascertained using KPNC's comprehensive electronic pharmacy records.
RESULTS:
We found no association between lipophilic statin use (>/=2 years vs. never) and overall breast cancer risk (OR(adj)=1.02; 95%CI=0.97-1.08) in conditional logistic regression models adjusted for oral contraceptive and hormone therapy use. Women who used lipophilic statins did not have a decreased risk of HR-negative breast cancer (OR(adj)=0.98; 95%CI=0.84-1.14), nor altered risk of HR-positive disease (OR(adj)=1.03; 95%CI=0.97-1.10). Furthermore, lipophilic statin use was not associated with risk of any of the intrinsic subtypes, luminal A, luminal B, HER2+/ER- or triple negative.
CONCLUSIONS:
Our results do not support an association of lipophilic statin use with the risk of breast cancer in general or with risks of HR-negative or other breast cancer subtypes specifically. Impact: These findings do not confirm previous reports of a possible preventive association.

Autosomal dominant HEREDITARY CANCER SYNDROME in which a mutation most often in either BRCA1 or BRCA2 is associated with a significantly increased risk for breast and ovarian cancers.

A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.
