Unopposed estrogen and estrogen plus progestin menopausal hormone therapy and lung cancer risk in the NIH-AARP Diet and Health Study Cohort.

ABSTRACT:

Purpose

Previous studies have reported that lung cancer risk may be decreased, increased, or unaffected by prior use of menopausal hormone therapy (MHT).

Methods

To assess this issue further, we examined relationships among 118,008 women, ages 50-71 years who were recruited during 1995-1996 for the NIH-AARP Diet and Health Study and in whom 2,097 incident lung carcinomas were identified during follow-up through 2006. Multivariable Cox proportional hazards models estimated relative risks (RR) and 95% confidence intervals (CIs) associated with various measures of self-reported MHT use.

Results

We found no evidence that either estrogen therapy (ET)-only or estrogen plus progestin therapy (EPT) use was substantially related to subsequent lung cancer risk (respective RRs a
