Ms2185 - An analysis of the effect of statins on the risk of non-Hodgkin's lymphoma in the Women's Health Initiative cohort

Desai P, et al. Cancer Med. 2018 Apr 2. doi: 10.1002/cam4.1368. [Epub ahead of print]
Background: Statins are the most widely prescribed class of cholesterol lowering drugs and by acting as a competitive inhibitor of the rate limiting enzyme in the mevalonate pathway (hydroxyl methyl glutaryl coenzyme A (HMG CoA) leads to lower levels of down-stream products which may have implications for cancer chemoprevention.   

Methods: We used data from the WHI's observational study (OS) and clinical trial (CT) to analyze the relationship between statin use, type, potency, and lipophilicity with risk of Non Hodgkin's Lymphoma (NHL), overall and NHL subtypes.   The study population included 161,563 women from which there were 712 cases of NHL diagnosed after 10.8 years of follow-up.  We used multivariable adjusted HR and 95% CI to evaluate the relationship between statin use at baseline, as well as in a time dependent manner.  Separate analyses were performed for individual NHL subtypes including Diffuse large B-Cell lymphoma (DLBCL), follicular lymphoma and small lymphocytic lymphoma. 

Results:  In our time dependent models, statin use was associated with a borderline lower risk of NHL (HR 0.81, 95% C.I. 0.66-1.00). Considering histologic subtypes, statin use was associated with a lower risk of CLBCL (HR 0.62, 95% C.I. 0.42-0.91), but not other sub-types. Interestingly, this lower risk was driven by lipid soluble statins (HR 0.62, 95% C.I. 0.40-0.96), which included atorvastatin, simvastatin, lovastatin and fluvastatin.

Conclusions: These results may have impact on primary prevention in patients at high risk of NHL or secondary prevention in patients who have a high risk for relapse (higher stage of disease and high risk biology), particularly for DLBCL.

Ms1750 - An analysis of the association between statin use and risk of endometrial and ovarian cancers in the Women's Health Initiative

Desai P, et al. Gynecol Oncol. 2018 Mar;148(3):540-546. doi: 10.1016/j.ygyno.2018.01.006. Epub 2018 Feb 13.
Background: Endometrial and ovarian cancers commonly carry mutations in pathways affected by the inhibition of the mevalonate pathway suggesting that these cancers may be potential targets of preventive strategies utilizing statins. 

Methods: We used data from the WHI's observational study (OS) and clinical trial (CT) to analyze the relationship between statin use, type, potency, and lipophilicity with risk of endometrial and ovarian cancer. The study population included 161,808 women from which there 1377 cases of endometrial cancer and 763 cases of ovarian cancer after 10.8 years of follow-up.  We used multivariable adjusted HR and 95% CI to evaluate the relationship between statin use at baseline, as well as in a time dependent manner.   .

Results: Using multivariable adjusted models; we found a lower risk of endometrial cancer among users of baseline statins users (HR 0.74, 95% C.I. 0.59-0.94) but not when time dependent statin use was taken into consideration (HR 0.91, 95% C.I. 0.76-1.08). Statin use was associated with a higher risk of ovarian cancer (HR 1.30, 95% CI 1.04-1.62) which was mostly driven by pravastatin use (HR 1.89, 95% CI 1.24-2.88).

Conclusions: There was a reduction in risk of endometrial cancer among statin users at baseline but not in time-dependent models. Pravastatin use was associated with an increased risk of ovarian cancer.  Analyses of larger numbers of cases are needed to further evaluate these findings.
